Definitions

  • the invention relates to a crane cable car with a load suspension that can be raised and lowered by means of the pull rope after clamping the suspension cable, and with a control that switches at any stopping point from driving to crane operation, in which the suspension cable is clamped and the load suspension is unlocked , whereby the re-locking load suspension switches from crane operation to driving operation by releasing the suspension cable clamp.
  • Such crane cable cars are known in various designs. Since the traction cable is used on the one hand to move the cable car and on the other hand to lift and lower the load when the carrying cable is clamped, a change of the operating mode is necessary if possible without any special external influence.
  • a structurally simple solution is achieved by a wireless remote control, as is known from AT-PSen 179 555 and 183 447; however, their main disadvantage is the risk of possible malfunctions that involve an unacceptable security risk.
  • the AT-PS 194 439 shows a purely mechanical solution, the control part of which is structurally complex, especially in the crane cable car relatively large forces have to be generated which initiate the clamping of the suspension cable and enable the change of operating mode.
  • Hydraulic devices are therefore already used (AT-PSen 177 159, 297 795, 328 505), which can generate the relatively large forces without any problems, but the charging of a pressure container takes place via an oil pump driven by moving crane cable car.
  • these crane cable cars still have the disadvantage that two stops must be at a distance which enables the pressure vessel to be charged. Stops that are less than twenty-five meters apart pose considerable problems that can only be solved with special tricks.
  • the invention has now set itself the task of creating a crane cable car of the type mentioned, the main advantage of which is that the crane cable car can be used again in crane operation immediately after leaving the stop area resulting from fluctuations.
  • a rope element is assigned a detection element that registers a stop
  • the control has an electronic circuit which, when the stop is registered as driving operation, triggers an electrical switching element of the operating mode changing device with a time delay and a new one after the crane operation has been completed Control only allowed after a time and distance delay.
  • Stopping here means not only absolute standstill, but also fluctuation-related movements that do not exceed a certain path length, for example between two and four meters, at most five meters.
  • the length of the route after which the crane operation can be used again is significantly less.
  • two changes of direction of rotation of the rope pulley which result from the fluctuations of the pull rope in almost every stopping situation, can be used if at most ten turns of the rope pulley take place between them.
  • three to five such revolutions are sufficient to compensate for the fluctuations.
  • a route of up to five meters can be selected between the changes in direction of rotation, which is still regarded as a stop.
  • a driving distance of one and a half to two and a half meters is generally sufficient.
  • the time-delayed activation of the switching element is intended to calm the stopped crane cable car as well as a load attached to it.
  • An adjustable, first delay time between three and thirty seconds is preferably provided here.
  • the settling time depends on several factors, such as route length, possible column spacing, etc., i.e. the greater the length of the pull rope, the longer calming times are required.
  • the path- and time-dependent blocking of the controllability after locking the load hook in the load suspension is necessary in order to put the detection element out of operation both during a first time span and a first travel distance, despite the unchanged stop registration, since otherwise the immediate switch back to crane operation would take place .
  • a second delay time of ten seconds and a delay path of a circumferential length of the rope roller are preferably used here.
  • the coupling of time and distance makes it possible for the crane cable car to linger at the stopping point for as long as necessary with the crane hooks retracted.
  • contactless registration with optical means can be achieved, for example, in that a pulley carrying light-dark markings is rotatably connected to the rope roller, and a detection element is provided which records the intensity of the light-dark alternating rhythm.
  • the detection element can also respond to a change in rotating magnetic fields or to a change in eddies currents that are generated by a rotating magnetic field. It can be advantageous if the disk has a driver pin which engages in an arcuate, intermittent groove of the shaft of the rope roller, the disk being rotatably mounted on the shaft.
  • a spring-loaded disc brake is preferably assigned to the disc.
  • electromagnets can be used as electrical switching elements, which can serve as a solenoid for a trigger slide of a control mechanism, if the operating mode changing device is constructed exclusively mechanically, a control hydraulics or as part of a solenoid valve of a control hydraulics.
  • electrical switching elements for example a control motor with a control cam, etc., can also be rotated.
  • FIG. 1 shows a schematic oblique view of a crane cable car
  • FIGS. 2 to 4 axial sections through three different design options for the detection element
  • FIG. 5 shows a circuit diagram in connection with a control hydraulics
  • FIGS. 6 to 8 show schematic vertical sections through a crane cable car with control mechanism in the load suspension
  • FIG. 9 is a plan view of the load suspension in the position according to FIG. 6.
  • a crane cable car 1 according to the invention can be moved on a support cable 2 by means of a pull cable 6, which is guided over a winch.
  • One of the two running mechanisms 3 is provided with a rope roller 4 to which a detection element 5 is assigned. From this movement or movement change and standstill is registered, and the register Th signals are processed in an electronic circuit 9 in a manner explained in more detail below.
  • FIG. 2 to 4 show different versions of the detection element 5 assigned to the rope roller 4.
  • a disk 11 with light-dark markings is fastened on the shaft 17 of the rope roller 4.
  • This is assigned a photodetector 50, which transmits the detected brightness change values to the electronic circuit 9 by means of a corresponding evaluation part 51.
  • an idle detection of the rope reel rotation is achieved by means of a disk 12 rotating pulley, which is equipped with permanent magnets 52, and inductive sensors 53 assigned to them, which transmit the segments to the electronic circuit 9 via an evaluation board 55.
  • the detection element 5 shown in FIG. 4 operates according to the eddy current principle, in which an eddy current generator 54 is used and the changes in the induced eddy currents or signals derived therefrom are in turn fed to the electronic circuit 9 via the evaluation board 55.
  • FIG. 5 shows a circuit diagram in which the electrical switching element 10 actuates a magnetic switch of the control hydraulics 40.
  • the primary switching energy is generated by a hydraulic pump 42 driven by the carriage 18, which pumps the oil flow into the pressure accumulator 43.
  • the memory 43 acts on the check valve S-A with the pressure that is set on the pressure relief valve 44. After a few meters, the pressure is in the store 43 and the excess pressure escapes into the tank.
  • the electronics which detect the stopping of the crane cable car 1 are actuated after the time delay which can preferably be set as a function of the length of the pull cable 6 tion during which the fluctuations of the crane cable car calm down to a level predetermined by the electronics, the magnetic switch 10.
  • This actuates a trigger slide 41, which presses a control lever driver 45 against a switching spring 47, and is de-energized there again.
  • a control lever 46 engages on the control lever driver 45 by means of the compression spring 48.
  • the switching spring 47 now presses the control lever driver 45 and thus also the control lever 46 backwards.
  • the accumulator pressure present at the check valve SA is overcome by means of the large lever ratio and the check valve SA is opened by the control piston 40.
  • Pressure oil now flows from the reservoir 43 into the working cylinder, the clamping cylinder for the clamping of the clamping device 8 being supplied by an overflow only after the pivoting-in process has been completed.
  • the check valve SA is closed and the working cylinders can be emptied by opening the check valve AR.
  • the activation has taken place, the pull cable lock is active again and the relieved clamping is completely released after releasing the pull cable 6.
  • the electronic circuit 9 controls the travel and time delay until the next possibility of switching over to crane operation.
  • a control mechanism 20 influenced by the switching element 10 is shown, which is largely accommodated in the load suspension 7.
  • the electrical switching element 10 in this embodiment a lifting magnet, is actuated, which actuates a pivot arm 22 via an articulated trigger slide 21, which is actuated by one in bearings 24 (only one shown). protrudes rotatably and axially displaceable guide tube 23 through which the pull cable 6 is guided down to the load hook 39.
  • a control disk 25 is connected in a rotationally fixed manner to the guide tube 23 and has control arc-shaped slits 33, 34, 35 in which guide pins 26 slide.
  • the guide pins 26 are up from slide guides (FIG.
  • Each carriage 75 has a locking lug 73 which is suitable for engaging over a locking shoulder 72 on a control sleeve 36.
  • the control sleeve 36 is spring-loaded on an inner tube 71, in which the guide tube 23 is displaceable, and its upper end lies against the underside of the control disk 25.
  • a guide sleeve 37 is attached to the inner tube 71, which has diametrical longitudinal slots 38 and receives a compression spring 76. This is supported at the top on the inner tube 71 and at the bottom on a plate 77 which is guided in the longitudinal slots 38 with projections projecting outwards.
  • spring-loaded locking levers 70 are rotatably mounted in the closed position, which cooperate with the downwardly projecting end sections of the carriage 75 when they are in their lowermost position.
  • the slide 75 sliding on slide guides 28, 29 is assigned Bowden cables 78, 79, one of which causes the clamping device 8 to be pivoted in and the other to be pre-clamped.
  • the control mechanism shown in FIGS. 6 to 9 works as follows: When an arbitrarily select stopping point is reached, this is registered in the manner described by the detection element 5 and transmitted to the electronic circuit 9, which is supplied by a current source 19, for example a battery, which, after an adjustable delay between 3 and 30 seconds, the switching element 10 thus controls the solenoid. From the driving position shown in FIG. 6 with the clamping device 8 open and swung out and the load hook 39 locked by the locking lever 70, the control disk 25 is rotated via the switching element 10, the trigger slide 21 and the guide tube 23.
  • the guide pins 26 slide outwards in the control slots 33, 34, 35, unlock the spring-loaded slides 75 by pushing the slide guides 28, 29, 30 outwards. Since the control slots 33, 34, 35 are bent differently, a trigger sequence arises.
  • the slide guide 28 is pivoted out first, so that the slide 75 pivots in the clamping device 8 via the Bowden cable 78, followed by the pivoting out of the slide guide 29, the slide of which actuates the Bowden cable 79 and pre-clamps the clamping device 8 on the supporting cable 2.
  • the remaining two control slots 35 are of the same type, so that the slides 75 are released last on the slide guides 30, which open the locking levers 70 with their lower ends when they move downward, so that the load hook 39 is released.
  • the guide pins 26 engage again in the control slots 33, 34, 35, and the control disk 25 moves down together with the guide tube 23, the spring 76 pushing the plate 77 into the lowest position, with the tension cable 6 releasing, into the locking lever 70 Secure the load hook.
  • control hydraulics 40 it would also be conceivable to replace the magnetic switch 10, trigger slide 41 and the two check valves with a 3/2-way valve to which two individual magnetic switches are assigned.
