Definitions

  • couplers are used for locating and locking each of the four bottom corner fittings of a container either to the corner fittings of another container or to structure below it.
  • These couplers come in various designs all compatible in size with the elongate apertures to be found in the horizontal faces of the corner fittings of a typical shipping container.
  • a common coupler is one called a semi-automatic twistlock or 'SAT'. This has an elongate head and tail joined by a shaft which rotate within an elongate collar. The rotation is needed to, for example, lock both head and tail inside the corner fittings of upper and lower containers to hold them together.
  • the elongate head of the SAT described is known to be of a ridged conical shape such that when a corner fitting of a container with known bottom sockets is lowered onto the head with its head rotated out of its open position the head is driven by the action of the sides of the socket acting on the ridges causing the head to rotate to align longitudinally with the elongate socket and easily enter the socket where upon it then rotates back automatically driven by its internal springs to its locked position inside the fitting.
  • the internal torsion springs of the SATs in general can be inadequate to drive the head past blemishes such as damage, dirt and corrosion that is inevitable under the heavy use of containers and their SATs, and ensure full locking inside the fittings.
  • Some SATs have a head and tail rotation which is clockwise when viewed from underneath to unlock the head from a corner fitting above.
  • Other designs operate in the opposite direction so a means to be able to work with one or other of the SATs is desirable.
  • a rig for connecting or disconnecting container couplers to or from the four lower corner fittings of a shipping container, the rig comprising two pairs of corner units held in the required transverse special relationship by a structure extending between the two corner units of each pair to form two operating modules, and a base member having sockets and/or other connectors to secure the operating modules to the base member to enable the corner units of the modules to simultaneously engage all the four lower corner fittings of a container lowered onto the rig, each corner unit including an indexing means for engaging and manipulating an associated coupling to connect or disconnect the coupling to or from its associated container corner fitting.
  • the sockets and/or other connectors may be positioned to enable the operating modules to be secured to the base member in a plurality of longitudinally spatial relationships so that containers of different lengths or using different types of couplers can have their lower corner unit engaged simultaneously.
  • Such a rig greatly speeds up connecting or disconnecting container couplers to or from the lower corner fittings of a shipping container and avoids the necessity for personal to get close to or underneath containers during such operations thus greatly improving the safety of personnel.
  • the rig also allows handling of different lengths of container and containers with different types of coupler greatly improving its efficiency.
  • the rig of the present invention has overcome this problem by providing a corner unit which can manipulate the coupler to ensure its connection or disconnection without requiring manual intervention.
  • Figure 1 shows a shipping container being lowered onto a rig in accordance with the present invention
  • Figure 2 shows two rigs joined together in a side by side configuration for easier handling and processing two containers simultaneously;

  • FIG. 1 of the drawings shows a crane spreader 10 lowering a container 11 towards a rig 12 in accordance with the present invention which comprises a base member 13 and one or more pairs of end modules 14 each module having two corner units 15 joined by a transversely extending structure 25.
  • the corner units 15 are used for fitting or removing couplers 16 to or from the bottom corner fittings 17 of container 11 as will be described below.
  • the base member 13 of rig 12 is in the form of a rectangular frame having side members 18, end members 19 and cross members 19a. These members are provided with sockets 20 or other fixing means along the top of the frame members to allow several pairs of end modules 14, 14', 14" to be attached to the base member at different longitudinally spaced positions to allow containers of different lengths to be handled. In the example shown end modules 14 are positioned to handle 40ft containers, modules 14' will handle 45ft containers and modules 14" will handle 20ft containers.
  • the rig is also provided with end guide posts 21 and side guide posts 22. These guide posts may pivot down to allow more convenient storage of the base member of the rig or may be removable by, for example, being inserted into pockets 23 in the side members 18.
  • guide posts may be replaced by or augmented by guide plates 44 (see figure 7A) mounted on the corner units 15. It is envisaged that the side and end guides could be fitted to the base members as shown or if the end modules are made taller and stronger be fitted to the ends and sides of the end modules themselves.
  • Each end module 14 has two corner units 15 joined by a transversely extending structure 25.
  • This structure 25 may house actuating means for the corner units 15 (which is described below).
  • Other equipment such as boxes, battery packs, solar panels etc. can too be housed in the structure 25 or alternatively or additionally be housed in or on the base member 13.
  • the structure 25 or base 13 may also house a proof load to enable the rig to test the strength of the corner fittings and couplers as described and claim in the Applicants co-pending application No. PCT/2019/000067.
  • Each module may have one or two pairs of couplers which connect with pairs of the sockets 20 in the base member.
  • the container being lowered is supported on the top plates of the corner units.
  • the container is not supported on the top plate 310 (see figure 6) of the corner units of the end modules but on support members carried by the base member which hold the container at the required during connection /disconnection.
  • These support members may be rigid components carried by the base member or can be resilient cushioning components 27 mounted on side members 18 some of which are shown in figures 1 and 3.
  • cushioning components 27 reduce the impact of a heavy container 11 landing on the corners units 15 of modules 14 when SATs are being handled or, in the case of the FATs, where the corner posts do not support the container, the cushioning components 27 support the weight of the container above the FAT corner unit to allow the FAT corner unit to perform its operation.
  • the support members act upwards onto the floor bearers 75 of base structure 11a of the container which as defined by ISO 1496 standards are positioned and intended to be able support the container if required.
  • Figure 3A shows part of a 40ft container 11 being lowered onto rig 12 for the connection to the container of SATs 28 supported in corner units 15 of the end modules 14 and the cushioning components 27 reducing the impact of heavy container 11 landing on the corners units of modules 14.
  • the end modules have flip up corner adaptors 29 which can be pivoted (see arrow Y) about pivot pin 304 from an inactive position 29' to an active position over the top of top plate 310 at each corner unit to provide a standard socket for the spreader twistlocks to connect to the end modules and lift as denoted by arrow W.
  • Two end modules can be seen in figure 3C showing how with the adaptors 29' still folded the modules can also be stacked. If the modules are to be connected together then the adaptors 29 are raised and SATs 16 can be fitted between the sockets 31 in the bottom plates 306 of the modules and the adaptors 29.
  • the adaptors 29 need not be pivoted but could be loose or chained items lifted or moved into place on the top plate 310 and incorporate a connector such as a rotating tail 104 or similar to be locked to the top plate.
  • the weight of the modules is balanced centrally under the raised flip up corner adaptors 29 so that the modules hangs squarely below the spreader 10 with their centres of gravity passing through or close to a horizontal centre line joining the lifting centre denoted line 303 of the two corner units of each module.
  • the lifting forces pass through the adaptor 29, through the pivot pin 304 and thence to the end module 14. If the end modules 14 are attached to the base 13, then that too is lifted.
  • side members 18 or additional longitudinal rails could be fitted with known retractable roller conveyors so that should a module be required to be moved from say the 40ft position to the 45ft position, it can be raised up by the roller conveyor acting on the underside of the module sufficient for the connectors between module and base member to clear and then be conveyed
  • Figure 2 shows two rigs 12 located next to each other seated on top of two transverse adaptor beams 30 one at each end. Note that one container being handled on one base member is a common use of the rig but this example shows the modularity of the rig and how two such rigs can be operated simultaneously.
  • the adaptor beams 30 lock to sockets 20 also provided along the underside of the base members 13 of the two rigs. The adaptor beams keep the rigs orientated in the correct position so that the two 40ft long containers 11 can be lowered towards the base members simultaneously.
  • the base members have end guide posts 21 and side guide posts 22 as referred to above.
  • the end guide posts 21 are hinged by large diameter tubes through the base member 13 (or could be similarly hinged on the end modules 14) and can be locked in the erect position or folded down when not in use.
  • the side guide posts 22 slide within pockets 23 in the base (or as envisaged in the sides of the modules 14) to allow adjustment for different width containers to fit between them. They can be fitted to both sides of each base member or as shown in figure 2 on one side only. All guides can be removed for compact shipping.
  • the containers show couplers 16 in their bottom fittings for removal (or fitting in the converse). The guide posts guide the containers so as to align the couplers with the corner units for removal.
  • the two rig arrangement shown in figure 2 can be lifted side by side especially when connected together with the adaptor beams 30 and using, for example, a container lifting beam arrangement as described and claim in the Applicant's application No.
  • Figure 5 shows how rigs 12 can be stacked with the end modules 14 still attached.
  • the end modules 14 can have their flip up corner adaptors 29 raised for connecting the stacked rigs together and to transmit stacking forces through to ground.
  • the stacked rigs can be transported on, for example, a trailer as shown with the guide posts 21, 22 and projecting components such as cushions 27 removed, folded, deflated etc. to enable the stacked rigs to be shipped, stored, transported on existing container infrastructure.
  • modules not necessarily those with end modules, can be devised for use with the rig such as battery packs, solar panels, generators, connector storage boxes, detection devices, for coupling with the base member sockets 20 or other fastenings and conforming to the need to seat low enough to not foul the underside of containers or rigs stacked over them on end modules or cushioning components 27.
  • Figure 6A shows details to one side of a typical end module 14 with a SAT 103 shown with its head 106 and tail 104 both in the locked position illustrating how it would look if it had just been connected to and lifted by fitting 17' shown in dotted lines.
  • the four sockets 31 (only one shown) in the bottom plate 306 allow connection of the end module to the base member 13 or to another end module when stacking for storage.
  • the flip over corner adaptor 29 is shown in its stowed position 29'.
  • Each corner unit has its own internal mechanisms (examples of which are given below) for manipulating couplers such as SATs 103, 310 and FATs 42, 90 in order to connect or disconnect such couplers to and from shipping containers lowered onto the rig.
  • Batteries 32 are shown in this example and provide the power to an actuating means in the form of, for example, a linear electric actuator 33 which in this example drives a mechanism in the form of a lever 307 in either direction, pivoted about pin 308, through a resilient component 36 to a pin 309.

  • the free end of the lever is connected to a driving means comprising here a chain 35 so that as the lever is displaced it drives the chain in the direction of arrows V causing the sprocket 311 to rotate and with it the indexer 34.
  • Figure 6A also shows an operating toggle wire 350 of the SAT 103, which, in the known manner is used to move moves the SAT between its various rotational positions.
  • This wire is supported on a guide 351 on the top of the corner unit.
  • the guide 351 holds the toggle wire 350 clear of the known toggle wire catches 352 and 353 positioned above, below and to the side of the toggle wire to ensure that the efficient operation of the SAT during use of the rig.
  • a clip or magnetic catch or inclined side guides 82 can be used additionally to guide the wire on guide 351 if required.
  • the chain 35 is connected to the righthand corner unit 15 of the end module 14 as illustrated and to the left hand corner unit (out of view) activating a sprocket and indexer and SAT as described simultaneously. Coordinating the two corner units has the benefit of preventing rotation of both tails 104 in the event that one tail is not fully inserted in the indexer.
  • the resilient component 36 should the FATs or SATs being handled by the indexers 34 encounter any obstruction during their connection or disconnection, allows the indexers to continue to urge the displacement of the FATs or SATs without any damage occurring to the drive mechanism or the actuator.
  • the component 36 comprises a box containing a sliding block 315 connected to the drive rod 316 of the actuator 33 that slides fore and aft against pre-loaded compression springs 317.
  • the box 36 is connected with lever 307 via a rod 316a which is connected with pin 39.
  • the springs 317 keeping the block 315 centrally within the box 36 unless the actuation of the actuator 33 reaches an obstruction when a one spring compresses more and the other less.
  • FIG 6B there is seen an example of a flat headed SAT 103 with flat topped head 106 being offered up to the socket 54 in the bottom of the corner fitting.
  • the lines 108 indicate the width of the socket and it can be seen that the socket is too narrow for the head 106 to enter resulting in the bottom face of the fitting abutting the flat topped head 106.
  • the known conical head 111 easily enters the socket 54 and as it progresses into the socket, the head 111 is rotated as known until it enters the socket.
  • the corner unit it is necessary for the corner unit to rotate the head 106 to align with elongate profile of the socket 54 and allow them to mate.
  • the linear actuator 33 is then activated to drive the lever 307' to position 307 thus rotating the head 106 into alignment with a socket 54 so that a container with fitting 17' can be lowered fully over the head.
  • the actuator is then activated to drive in the opposite direction and the head 106 is rotated to lock inside the fitting 17'.
  • SATs 103 and 110 When SATs 103 and 110 are being lowered hanging from the container positioned as couplers 16 in figure 1, they are typically set with the tail 104 aligned with the elongate sockets similar to socket 54 as seen in figure 600A. From this halfway rotated position of the tail, to remove rotate the head 106 to release it from the fitting 17, it is only necessary to rotate the tail (and thus head) by a lesser angle than when fitting a SAT. So, looking at figure 6 the actuator can be re-positioned for SAT removal by driving the actuator and thus the lever to a midpoint between position 307 and 307'.
  • the tail inserts straight into the indexer 34 and once there the actuator is activated to pull the lever to position 307 and with it rotate the indexer and the tail of the SAT and thus unlock the head 106 from the fitting 17 enabling the socket 54 of the fitting to rise clear disengaged with the head.
  • the actuator is powered by one of a number of known power sources such as batteries, mains power, hydraulics, pneumatics or energised springs retained by triggered catches.
  • the rotation of the sprocket 311 is less than 140 degrees and therefore the sprocket could be replaced by levers similar to lever 307 and its pivot 308 be sited on a transverse line joining axis P of the corner unit the levers being pinned to each other by a driving means comprising a transverse rod pushed and pulled by the actuator 64 so that the levers act in unison.

  • Compression springs 41 pinned to the base 40 hold the corner unit in a substantially vertical position but enable it to be displaced (sideways, lengthways and vertically) by the action of a FAT 42 finding its way into a socket 43 of the corner unit or as the container corner fitting 17 (partly cut away to reveal workings) encounters guide plates 44 as the container is lowered.
  • a vibrator 112 comprising an electric motor with offset load is mounted on the corner unit which when vibrating induces medium frequency impacts between the moving surfaces of the FAT 42 and the fitting 17 thus enabling the indexer to displace the FAT more easily and overcome snags, friction, dirt and small distortions in the surfaces of the fitting 17.
  • Only one of the guide plates 44 is shown in figure 7, the guide plate at right angles to that shown has been removed in this figure for clarity.
  • An actuating means in the form of a linear actuator 64 is mounted pivotally between the structure of the end module 14 and the front of the box 47.

  • the FATs typically have horizontal probes or noses 68 and 81 which extend the heads 57 inside the fittings 17 and can overlap the apertures 54 so that when lying close to the apertures 54 further displacement action of the corner units 15 to free the FATs from the fittings 17 is necessary.
  • the steel surfaces can be rough and damaged so raising of the head within the fitting is advantageous to help clear these obstructions. So during operation it is necessary to move the FAT vertically upwards and horizontally to a free central position, seen in figure 10, so the head 57 with its noses 68 and 81 and the collar 63 clear the geometry of the interior of the fitting including the aperture 54 to a position where only rubbing slidable contact is made with the interior throughout its rotation when activated. Where a shoulder key 28 is provided the upwards lift must be sufficient to clear this key from the socket aperture 54.

  • the actuator is mounted to provide a horizontal and vertical components of force to match the reactive requirements of the pins 49 as they slide along slots 50, 51 without jamming.
  • the shape and location of the slots is determined by the matching of the geometry of each design of FAT to that of the fitting 17 so as to guide the FAT along a locus which ensures its release or fitting from or to fitting 17.
  • the head 57 when operating on one type of known FAT, the head 57 is moved relative to the container, then the head 57 is rotated to align with the socket aperture 54 which typically is when sides of the collar 63 abut sides of socket 54, then a counter clockwise tilt
  • a vibrator 112 seen in figure 7B may be provided which can be energised to cause the FAT to free itself from small snags and shapes often found within cast steel and fittings of the type used in the fittings 17 and FATs 42.
  • the coordinated movements of the motor 66 and actuator 64 which carry out the above movements of the coupling are achieved with a programmable computerised controller further enhanced by sensors to verify any errors encountered during the movement due to snagging and the like, backed up by the action of vibrator 112.
  • the controller programme defines the displacements, speed of deployment, and force at different times and phases of the operation.
  • Fitting FATs 42 to containers 11 with fittings 17 is achieved by reversing the procedure described above for removing a FAT.
  • a FAT is placed in the socket 43 and a container 11 is then lowered onto the supports 62 being guided by guides 9.

  • the driver and box may be combined and this combined box/driver component is then changed to handle different couplers.
  • Figure 13A shows a FAT 42 in the socket 43 of a driver 45 with the axis E of fitting aperture 54 aligned with the axis D of the head 57 and the collar of the FAT so that the FAT can be rotated and unlocked from the aperture 54 and then removed as described earlier.
  • Figure 13B shows how an adaptor 100 which consists of a plate 101 with an aperture 102 similar to socket aperture 54 can be positioned on top of the corner unit so that if a SAT 103 is offered up to the corner unit 15 rotation of the tail 104 of the SAT can be carried out by the same corner unit mechanism as used for FATs.
  • the adaptor plate 101 can be pivotally mounted at 105 on the corner unit for swinging movement between an inactive position shown in Figure 13A and an active position shown in Figure 13B.
  • FIG. 14A shows container 11 with its corner fitting 17 with its socket aperture 54 being lowered towards the head 91 of a FAT 90.
  • the FAT 90 has tail 94 inserted into socket 164 of indexer 144.
  • the socket 164 is of elongate shape similar to aperture 54 in fitting 17 described above so that hook end 95 of FAT 90 engages inside the socket 164 and the intermediate plate 103 of FAT 90 is supported close to indexer 144.
  • a leaf spring 165 mounted within bracket 171 is set there to urge the tail 94 of the FAT upwards and unimpededly support it so that the intermediate plate 103 is above the indexer 144 by some 4 to 10mm.
  • This spring 165 helps the FAT 90 to free itself from the aperture 54 and in the case of the FAT claimed in DE102012201797 it is necessary to raise the FAT 90 up to clear its aperture plugging shape before it is able to be rotated. It is envisaged that other springs or biased guides can be provided to support and offer up the FAT 90 to the aperture 54 yet allow deflection as insertion forces between fitting 17 and indexer 144 come naturally into play.
  • the position of the indexer 144 with socket 164 is such that head 91 of the FAT 90 is aligned with the socket aperture 54 in the fitting 17 so that as the container 10 is lowered the head enters the aperture 54.
  • a torsion spring 158 wrapped around the shaft 130 and which in this position biases the bracket 171 with indexer and handle 123 to rotate counter clockwise, prevented in doing so by the handle 123 bearing on catch 84 being part of catch assembly 73 mounted and operated as described earlier.
  • the spring 158 is fixed to the bracket 171 at one end and a gear box comprising gear 163 and 162 driven by handle 161 fixed by conventional means not shown here to the structure 70 of corner unit 15 at the other.
  • FIG 14B there is seen the base 160 of container 11 coming to rest on the top 159 of structural member 70 and the fitting 15 making relatively light contact with the intermediate plate 103 of FAT 90 contact being maintained by a spring 165.
  • Top 86 of plunger 72 is at this point in the sequence pressed downwards by the base 160 of the container which causes it to press down on catch assembly 73 to position 73' thus lowering the catch 84 and releasing the handle 123 in turn allowing the shaft 130, bracket 171, indexer 144 and FAT 90 to rotate typically about 70 degrees counter clockwise thereby locking the head 91 of FAT90 inside fitting 17.
  • FIG 14C the container 11 is seen lifted away from the corner unit 15 taking with it the FAT 90 and allowing the plunger 72 to rise up and likewise catch assembly 73.
  • the hook 95 of FAT 90 slides out of the socket 164 by known means entailing a horizontal transverse displacement of the hook 95 as it rises out of the socket.
  • FIG 14D the back 157 of the FAT 90 is seen opposite the hook 95.
  • the container 11 has engaged in its fitting 17 the FAT 90 and is seen being lowered towards the corner unit 15.
  • the socket 164 is seen aligned with the tail 94 of the FAT and the socket 54 of the fitting 17.
  • a block 155 with stop 156 is fixed to the structure 70 below the rotating indexer 144.
  • the handle 123 abuts the catch 84 and in this position is being urged to rotate clockwise by spring 158.
  • Spring 158 has had its bias reversed by dint of gear 163 being driven in reverse by gear 162 with handle 161 moving from position 161' to position 161" (see figure 14E).
  • the gear ratio of gear 162 to gear 163 is devised to be preferably 4:1 so that from a 1 ⁇ 4 turn of the handle 161 in either direction from a neutral position between 16 and 161" a rotational deflection of the torsion spring 158 of 360 degrees can be achieved.
  • Friction and jamming of the FAT in the aperture 54 might tend to lift the FAT 90 up with the container 11 so to hold the FAT down within the corner unit 15, hook 95 is held within the socket 164 by the location of stop 156 sufficient to prevent the hook sliding out from within the socket yet enabling the FAT 90 to tilt and move to free itself from contact with aperture 54 urged on by the direction and support of spring 165.

  • Several frames 70, 70' could be located side by side for faster processing large numbers of containers and fitted as required with different models of corner units 206 should different types of SATS or FATs need to be processed without involving conversion of the mechanisms within them.
