Definitions

  • the invention relates to a cable hoist of a crane, in particular a container crane, with two trolleys which can be adjusted at a distance from one another and which, for pendulum damping, are connected to the load and have stay cables which diverge in the direction of travel plane.
  • the invention has for its object to provide a rope hoist for the purpose described, in which a sufficient inclination of sway damping cables is maintained even when lowering or lifting the load through narrow shafts. This object is achieved in a cable hoist of the type mentioned in the features of the characterizing part of claim 1.
  • the invention has the advantage that the lifting cables carrying the load always run vertically and therefore no fluctuations in the lifting forces occur. Another important advantage is that the inclination of the stay cables used exclusively for the pendulum damping can be changed almost arbitrarily according to the requirements of the crane operation. In order to achieve the maximum inclined position of the stay cables, they preferably engage the load or its receiving means in the vertical load center plane.
  • a further preferred embodiment of the invention consists in that the essentially vertical hoisting ropes engage on idlers which are arranged in pairs on both sides of the load or the load suspension means and with their axes symmetrical to the vertical load plane.
  • the lifting rope attachment points can be arranged as far as possible on the outside of the load suspension device or the crossbeam, which in addition to good pendulum damping also opens up the possibility of the load tipping in all directions (so-called list and trim movements) ).
  • a container hangs on a crossbeam 2 serving as a load-carrying means, which, on its longitudinal extension at both ends of which is assigned paired supporting rollers 3c and 4c, which deflect lifting cables 13 and 14, and supporting rollers 5c and 6c for guiding stay cables 15 and 16.
  • the support rollers 5c and 6c are arranged coaxially in the load center plane indicated by chain lines 7 and extended beyond the load 1, while the support rollers 3C and 4c are arranged near the corners of the cross member 2 symmetrically to the load center plane.
  • the hoisting ropes 13 and 14 are wound on the drum 3 of a winch which is arranged in a stationary manner on the crane frame (not shown) and, starting from here, also via fixed rope pulleys 3a and 4a, which are assigned to one end of the crane frame and extend as a boom, parallel to the crane boom to a guided main cat 8, which can be moved along the trolley track arranged on the crane boom.
  • the main trolley 8 has at its end assigned to the ropes 13 and 14 a pair of axially parallel rope pulleys 3b and 3d, which is assigned to the lifting rope 13 and the supporting roller 3c, and accordingly lies above the supporting roller 3c during operation, while the lifting rope 14 is one
  • a pair of axially parallel rope pulleys 4b and 4d is assigned, which belongs to the support roller 4c.
  • the rope 13 coming from the rope reel 3a is subsequently deflected downwards via the rope reel 3b and fed to the support roller 3c, from which it takes its way over the rope reel 3d and from there again in the horizontal direction along the crane lane a fixed point 3e, which is assigned to the other end of the crane boom.
  • the cable 14 takes its way from the cable pulley 4a via the pulleys 4b, 4c and 4d to the fixed point 4e arranged next to the fixed point 3e.
  • the stay cables 15 and 16 which serve to dampen the pendulum, are received by a cable drum 5 coaxial with the drum 3. From here, they run in a corresponding cable guide, as applies to the lifting ropes 13 and 14, over rollers 5a, 5b, 5c, 5d or rollers 6a, 6b, 6c, 6d, each to a fixed point 5e or 6e.
  • the rollers 5b and 5d as well as the rollers 6b and 6d are each arranged coaxially in pairs.
  • the rollers 5b and 5d are mounted on an auxiliary trolley 9 which is arranged next to the main trolley 8 with respect to their direction of travel, while the rollers 6b and 6d of a further auxiliary trolley 10 which are arranged on the other side of the main trolley 8 are arranged.
  • Lifting ropes 13 'and 14' and stay cables 15 'and 16' are correspondingly and symmetrically assigned to the other end of the traverse 2, to which, in addition to the corresponding cable drums 3 'and 5', the corresponding cable and support rollers also belong.
  • the rope guide is not fully extended in the figure for the sake of clarity. In the case of the movement of the main trolley 8 and the auxiliary trolleys 9 and 10 in any manner, the load 1 is not moved in the vertical direction without actuating the drums 3, 5, 3 'and 5' of the hoist, as is known per se.
  • the cable drum 5 is simultaneously designed as a storage drum and provided with a so-called standstill motor 21, as shown in FIG. 3, which compensates for the difference in length between the stay cables and the lifting cables as a tensioning device.
  • the motor 21 exerts such a moment on the drum 5 via a gear 22 that slack rope formation is avoided in the ropes 15 and 16, respectively.
  • This tightening device also includes a freewheel locking device 23 and a braking device 24, each of which is adapted to requirements in terms of its dimensions and setting.
  • the cable storage device can also be arranged at the other free and fixed end of the stay cables 15 or 16, ie at points 5e or 6e. In this case, the drums 3 and 5 could be combined into a single rope drum for the lifting and stay cables.
  • FIG. 4 Another embodiment of a cable storage device is shown in FIG. 4.
  • the stay cable 15 is guided over two rollers 5f and 5g, each of which is mounted axially parallel to one another at one end of a hydraulic cylinder unit 25.
  • the storage effect can be increased by using additional rollers, which then form a pulley arrangement.
  • the piston rod 26 of the hydraulic cylinder 25 By extending the piston rod 26 of the hydraulic cylinder 25 by pressurizing the piston 27 from the bottom, the distance between the rollers becomes 5f and 5g enlarged to each other and thus also the saved rope length.
  • the pressure oil is introduced from a tank 28 through a line 29 from a motor-driven pump 30 via a check valve 31 into the hydraulic cylinder.
  • a pressure relief valve 33 which is connected into a discharge line 32 branched off between the pump 30 and the check valve 31, is set in such a way that the pressure built up in the hydraulic cylinder is sufficient to prevent slack rope formation.
  • a directly connected between the line 29 and the drain line 32 further pressure relief valve 34 is set to a higher pressure, which means that a greater force must be applied when pulling off the cable 15 than when pulling the cable in by extending the piston rod 26.
  • the rope 15 is again attached to the fixed point 5e.
  • the stay cables can be equipped with a hydraulic pendulum damping device which has two hydraulic cylinders 5h and 6h, the cylinder 5h engaging with its piston on the axis of the cable pulley 5a and correspondingly the piston of the cylinder 6h on the axis of the cable pulley 6a, as shown in Fig. 1.
  • Cables 5h 'and 6h' are of course assigned to the pulleys 5a 'and 6a' in a corresponding manner.
  • the associated hydraulic device with the two hydraulic cylinders 5h and 6h consists of a motor-driven pump 35, a gas pressure accumulator 36 connected in parallel, two check valves 37 and 38 as well as a pressure valve 40 and 41 connecting the respective hydraulic cylinder directly to an oil reservoir 39.
  • Fig. 5 shows an embodiment of the main trolley 8 and the auxiliary trolleys 9 and 10.
  • the main trolley is supported by four wheels 45 on two trolley rails 46ab, which are arranged on a bridge beam 47 of the crane boom.
  • the cable pulleys 3b, 3d, 4b and 4d of the cable hoist are located at one end and the corresponding pulleys in a symmetrical arrangement at the other end.
  • hydraulic cylinders 49 and 49 'located under cylinders 48 and 48' are articulated in a corresponding manner on auxiliary trolley 9 and main trolley 8.
  • the hydraulic cylinders connected in pairs are used for adjusting the distance between the main trolley 8 and the relevant auxiliary trolley 9 or 10.
  • the auxiliary trolley 9 provided with the rope pulleys 5b, 5d, 5b 'and 5d' for the deflection of the stay cables is supported by two wheels 50 on the Trolley rails 46 and two wheels 51 on two trolley rails 52 arranged on the main trolley 8.
  • the auxiliary trolley 10 is provided on its outside with running wheels 53 and further running wheels 54, which are again supported on the main trolley 8 by rails 55.
  • the auxiliary trolleys 9 and 10 each have two cantilever-like arms 56 and 57 which hold the main trolley in the area of their rails 52 and 55 each overlap, as can best be seen from FIG. 6. From Fig. 6 it can also be seen that the two head ends of the main cat carrying the rope pulleys are connected to each other by a bracket 58 which is guided around under the bridge girder 47. Corresponding brackets 59 and 60 each have auxiliary cats 9 and 10.
  • FIG. 7 differs from that of FIG. 6 essentially in that the main trolley 61 carries the cable hoist, which consists of a coaxial drum 62.
  • the drum 62 is arranged in such a way that all the ropes run onto or from it in the extended load center plane 7.
  • the hoisting ropes 63 are outward deflected over the support rollers 64 arranged on the crossmember and are each fastened to the underside of the main trolley 61 in such a way that symmetry results with respect to the vertical load center plane 7.
  • One stay cable 65 is deflected via a support roller 66 arranged in the load center plane 7 and fed to a cable roller 67 which is arranged on an arm 68 of the auxiliary trolley 69 pointing downward.
  • the Schr ä gseil 65 connected via a further guide roller 70 to a holding means serving as tensioning hydraulic cylinder 71 and is connected to the end of its piston rod.
  • the hydraulic cylinder 71 is hinged at its other end to the auxiliary trolley 69.
  • the second auxiliary trolley 69 A has a hydraulic cylinder 71 A, which is guided with the second stay cable 65 A, which is guided around by the drum 62 via a support roller 66 coaxial with the support roller 66 A in the opposite direction of rotation.
  • the main cat is again connected to the two auxiliary cats via distance-adjusting hydraulic cylinders 72.
  • each of the two auxiliary cats is again supported on the main cat 61.
  • the hydraulic cylinders 71 or a separate drum of the cable hoist can serve as cable storage devices for the stay cables, which can be arranged symmetrically to the drum 62 with respect to the load medium level 7.
  • auxiliary trolleys with the main trolley via hydraulic cylinder units or via other suitable gear devices for adjusting the distance
  • connection of the auxiliary trolleys with the main trolley via hydraulic cylinder units or via other suitable gear devices for adjusting the distance has the advantage that only the main trolley needs to be provided with a travel drive.
  • self-propulsion is possible for all three cats, for which purpose it is useful to achieve one Synchronous speed-controllable electric motors are used.
  • Synchronous speed-controllable electric motors are used.
  • These can be superimposed on electrical speed controls to adjust relative speeds between the cats to adapt to specific requirements of driving.
  • the following automatic controls of the driving mode are expedient: When the auxiliary trolley approaching the end of the trolley track, both auxiliary trolleys stop while the main trolley continues to its possible end position. As a result, the track length is used while maintaining a large spread angle of the stay cables.
  • the lifting trolleys must be fully or a certain amount close to the main trolley during lifting operation at a certain lifting height so that the load can be guided through a narrow shaft.
  • the auxiliary trolley then moves at the same speed and is finished when the set lifting height is reached.
  • a number of other programming options for driving and lifting operations that relieve the crane operator are possible.
