Definitions

  • the present invention relates to an attachment means for attaching a load to a suspension element with at least one traction unit which serves to transmit force between the load and the suspension element and by means of which a length of the attachment element can be changed.
  • a load suspension device in particular a chain hanger, with at least one stop means with a first shortening device, and with a support means for a load. Furthermore, a hoist with a second shortening device is provided, which can be detachably connected to the stop means and parallel thereto.
  • the object of the invention is to improve the state of the art.
  • a sling for attaching a load to a suspension element is proposed.
  • the sling can be, for example, a chain hanger, wherein the sling can be arranged, for example, on a suspension element designed as a crane.
  • Such slings are used, for example, in civil engineering to move loads such as components, for example carriers, ceiling or wall elements, for building construction to the intended position.
  • the loads can also be boilers or reactors for chemical processes, heating boilers, road elements, bridge elements, rotor blades for wind turbines, pipes for pipelines or containers.
  • the sling thus has a load-bearing capacity of several tons. Even load capacities of up to 100 tons would be conceivable.
  • the stop means has at least one traction unit which is used to transmit power between the load and the suspension means.
  • the traction unit can thus take up the full load and transfer the force from the attached load to the suspension element.
  • a length of the stop means can also be changed by means of the pulling unit.
  • the traction unit can shorten the length of the sling when the traction unit is operated.
  • the traction unit changes, in particular shortened, its own length, so that the length of the stop means changes, in particular shortened.
  • the sling can essentially be lengthened again by at least partially throttling a power or a function of the pulling unit so that the pulling unit and thus the sling are elongated by the load.
  • the load for example the component
  • the load can also be aligned. If the load is, for example, a wall element for a building, care must be taken when installing the wall element that it is placed horizontally on a foundation. By changing the length of the lifting gear, the wall element can be aligned horizontally.
  • the sling has at least one securing arrangement which is designed to bridge the traction unit in order to ensure the transmission of force between the load and the suspension element even if this cannot be achieved with the aid of the traction unit due to the mass of the load or a technical defect in the traction unit more can be guaranteed.
  • the pulling unit can be driven hydraulically or electrically due to the high loads occurring in the range of several tons. In some situations it will be necessary to switch off or uncouple the supply to the traction unit. With the help of the fuse arrangement, which the Bridged traction unit, the power transmission from the load to the suspension means can still be guaranteed, even if the traction unit is out of operation or if the load would overload the traction unit.
  • the securing arrangement can thus secure the sling. In most cases, the pulling unit can only apply a pulling force during its operation, which shortens the sling. With the help of the securing arrangement, the load can be held, whereby the tension unit is relieved or can be relieved.
  • the securing arrangement has a length such that it takes over the power transmission between the load and the suspension element before a maximum operating length of the traction unit is reached.
  • the securing arrangement absorbs the force developed by the attached load before the maximum length of the pulling unit is reached.
  • the pulling unit is thereby protected from damage.
  • the maximum operating length is the length at which the pulling unit has the maximum length and is still functional, i.e. can still apply a force.
  • the pulling unit comprises a hydraulic cylinder, a pneumatic cylinder, a chain winch, a cable winch and / or an electric linear motor.
  • the chain winch and / or cable winch can be operated with an electric motor, for example.
  • the length of the stop means can be changed in a simple manner.
  • the hydraulic cylinder has a piston which is arranged in a working cylinder and is movable in its axial direction and which can be retracted and extended so that the length of the hydraulic cylinder changes. In this way, the length of the sling can be changed.
  • the hydraulic cylinder can be designed such that it can only apply force in one direction, namely in the pulling direction, so that the hydraulic cylinder itself can only shorten the length of the stop means.
  • the length of the hydraulic cylinder can, however can be extended again when the force applied by the hydraulic cylinder is reduced so that the load pulls the hydraulic cylinder in length.
  • the hydraulic cylinder is connected to a hydraulic pump in a known manner.
  • the securing arrangement comprises at least two securing elements which are arranged on both sides of the pulling unit.
  • the two securing elements are preferably arranged symmetrically with respect to the pulling unit. With two securing elements, the securing arrangement can take a higher load.
  • the securing elements in particular exclusively, can be subjected to a tensile force. Additionally or alternatively, the securing elements cannot be subjected to a compressive force. If the securing arrangement cannot be subjected to a compressive force, the securing arrangement does not hinder the pulling unit if it shortens the length of the slinging means.
  • the securing elements are designed as a chain, a rope, a band, a belt and / or a bracket. As a result, the securing elements can be designed in a simple manner.
  • the securing element can also be a rod.
  • the securing elements are arranged parallel to the pulling unit. As a result, either the securing arrangement or the traction unit can take up the load, the securing elements taking up the load in the secured state.
  • the securing elements bridge the pulling unit. This also allows the load to be absorbed either by the securing arrangement or the securing elements or by the pulling unit. If the securing arrangement is the traction unit secures, the load is taken up by the securing arrangement. When the securing arrangement secures the traction unit, the securing arrangement directs a force around the traction unit.
  • the stop means has a first connection unit and a second connection unit, wherein the at least one pulling unit is arranged between the first and second connection unit of the stop means and is connected to them.
  • the first and / or second connection unit can be a balancing rocker on which the traction unit is arranged.
  • the fuse arrangement is connected to the first and the second connection unit.
  • the securing arrangement and the pulling unit are connected to the two connection units, so that the load can be absorbed by the securing arrangement and / or by the pulling unit.
  • the securing elements are designed as a guide rod, with at least one of the two connecting units being guided on the guide rod. Additionally or alternatively, at most one of the two connecting units is fixed at one end of the guide rod. As a result, at least one end of the guide rod can always move with respect to the associated connection unit. Furthermore, the guide rod is designed such that the two connecting units are held on and / or on the guide rod. The connecting units are thereby guided on the guide rod and can change their distance from one another, so that the length of the sling can also be changed. However, by means of the guide rod, an orientation between the two connection units always remains fixed. The connection units are thereby guided like a slide on the guide rod. The guide rod can have a stopper at one end so that the connection units cannot slip off the guide rod when the Securing arrangement secures the train unit. A securing arrangement of this type is similar to a carriage guide.
  • the stop means has a first connection element, which is connected to the first connection unit, and / or a second connection element, which is connected to the second connection unit.
  • the first and / or the second connecting element can for example be designed as a chain, a belt, a band, a rod and / or a rope.
  • the first and / or second connecting element is used to lengthen the stop means or to adapt it in length.
  • a load suspension device for receiving a load with a suspension element and at least one attachment means by means of which the load can be attached to the suspension element.
  • the support means can be, for example, a crane, for example a truck crane, with the aid of which, for example, a component can be transported as a load for a building.
  • the loads can also be boilers or reactors for chemical processes, heating boilers, road elements, bridge elements, rotor blades for wind turbines, pipes for pipelines or containers.
  • the length of the sling can also be changed so that the load, for example the component for a building, can be transported to an exact position.
  • the at least one stop means is designed according to at least one feature of the preceding and / or following description.
  • the load suspension device advantageously has at least two stop means.
  • the load-bearing device can, however, also have three or four attachment means. This allows the alignment of the load to be changed if, for example, a sling is changed in length, whereas the other sling remains the same in length. As a result, the load can not only be precisely positioned, but also precisely aligned.
  • the load suspension device has an operating means by means of which at least one pulling unit of the sling can be operated.
  • the operating means can for example comprise a hydraulic pump, by means of which a pulling unit designed as a hydraulic cylinder can be operated.
  • the equipment and the pulling unit are of course connected to one another by means of pressure hoses.
  • the operating means can also be attached to the support means, so that a distance between the operating means and the pulling unit is as short as possible.
  • Figure 1 shows a sling 1 for hanging a load 2 on a suspension element 3.
  • sling means 1 are used, for example, in the construction of a building in order to move loads 2, such as ceiling or wall elements, to the intended position for the building.
  • the slings 1 can also be used to, for example, boilers or reactors for chemical processes, boilers, road elements, To move bridge elements, rotor blades for wind turbines, pipes for pipelines, containers or large motors as loads to the intended position.
  • the suspension element 3 can, for example, be a crane that transports the load 2 to the desired position. With the aid of the stop means 1, a connection between the suspension means 3 and the load 2 is established.
  • the sling means 1 has a load-receiving means 6, which here is designed as a hook.
  • the load suspension means 6 can also be connected to the stop means 1, in particular releasably.
  • an eyelet 7 is shown in this exemplary embodiment, by means of which the attachment means 1 can be hung on the suspension element 3, for example.
  • the sling 1 is detachably connected to the load 2 and / or to the suspension element 3 so that the load 2 can be uncoupled at the intended location on the structure.
  • the stop means 1 can also be decoupled from the suspension means 3.
  • the load 2 is secured on the attachment means 1 and the attachment means 1 on the suspension element 3 with the aid of a snap hook or snap lock.
  • the stop means 1 has a pulling unit 4 which is used to transmit power between the load 2 and the suspension means 3.
  • the pulling unit 4 thus transmits the force developed by the load 2 to the support means 3.
  • a length La of the stop means 1 can also be changed.
  • the length La of the sling 1 can be shortened with the aid of the pulling unit 4, in that the pulling unit 4 itself can change its own length Lz.
  • the pulling unit 4 can contract itself so that it shortens its length Lz itself.
  • the length La can also be lengthened again because the load 2 forms a tensile force due to gravity on the slinging means 1 and thus on the pulling unit 4.
  • the pulling unit 4 can thus be automatically extended again by reducing a pulling force formed by the pulling unit 4.
  • the change in the length La of the lifting means 1 is advantageous in order to be able to place the load 2 on the structure with a high degree of accuracy.
  • the pulling unit 4 can be a hydraulic cylinder which has a cylinder 8 and a piston rod 9 movably arranged therein.
  • the hydraulic cylinder is operated in a known manner not shown here by a hydraulic pump, the hydraulic cylinder being connected to the hydraulic pump by means of a line not shown here.
  • the hydraulic cylinder is operated in such a way that the piston rod 9 is pulled or pushed into the cylinder 8, so that the stop means 1 is shortened and the load 2 is raised.
  • the hydraulic cylinder is operated with less power so that the force of gravity of the load 2 pulls the piston rod 9 out of the cylinder 8 again.
  • other actuators are also conceivable as the pulling unit 4, such as pneumatic cylinders or electric drives, which are designed to be able to apply a pulling force that is sufficiently high in accordance with the load 2 in order to shorten the stop means 1.
  • the pulling unit 4 is thus designed to apply a relatively high pulling force itself in order to be able to shorten the stop means 1 in order to be able to lift the load 2 again.
  • their design cannot be designed to absorb the weight of the load 2 when the pulling unit 4 is out of operation, that is, when the pulling unit 4 itself is not applying any pulling force.
  • the Figure 1 this means, for example, that the piston rod 9 is pulled down completely by the load 2 and the cylinder 8 or a housing of the cylinder 8 has to absorb the weight of the load 2.
  • loads 2 of a few tons this can lead to damage and even complete Destruction of the pulling unit 4, so that even the load 2 can fall.
  • the pulling unit 4 can be put out of operation, for example, if a supply unit, such as the hydraulic pump, is shut down unexpectedly, for example due to a power failure.
  • the pulling unit 4 can be designed in such a way that it can take up the load 2 even when it is out of operation.
  • a check valve can prevent the piston rod 9 from being pulled out of the cylinder 8. The check valve thus prevents the pulling unit 4 from being lengthened. However, this can also be unsafe.
  • the stop means 1 has a securing arrangement 5.
  • the securing arrangement 5 is designed to bypass the traction unit 4 in order to ensure the transmission of force between the load 2 and the suspension element 3 even if this no longer occurs with the aid of the traction unit 4 due to the mass of the load 2 or a technical defect in the traction unit 4 can be guaranteed.
  • the securing arrangement 5 takes up the load 2 and transfers the force developed by the load 2 to the suspension element 3.
  • the pulling unit 4 can be relieved.
  • the securing arrangement 5 prevents the traction unit 4 from being loaded while it is itself out of operation, so that damage to it and the load 2 from falling is prevented.
  • the securing arrangement 5 advantageously has a higher tensile load capacity than the pulling unit 4.
  • the securing arrangement 5 advantageously has a length Ls which is designed in such a way that it enables the force transmission between the load 2 and the support means 3 takes over before a maximum length of the pulling unit 4 is reached. If the length Ls of the securing arrangement 5 is just as great as the maximum length of the traction unit 4, the securing arrangement 5 secures the traction unit 4 precisely when the traction unit 4 has reached its maximum length. If the length Ls of the securing arrangement 5 is shorter than the maximum length of the traction unit 4, the securing arrangement 5 secures the traction unit 4 before the maximum length of the traction unit 4 is reached. In this case, the pulling unit 4 cannot be fully extended, so that the pulling unit 4 is protected from damage. In order to secure the sling 1 or the traction unit 4, the securing arrangement 5 has a tensile strength that is sufficient to withstand the load from the suspended load 2.
  • the securing arrangement 5 is also arranged parallel to the pulling unit 4, so that the tensile force caused by the load 2 and acting on the slinging means 1 either acts on the pulling unit 4 (which is the case when the pulling unit 4 changes the length of the slinging means 1 La ) or acts on the fuse arrangement 5.
