Definitions

  • the invention relates to a device for rotatably supporting a cable drum with pivot bearings for receiving a shaft of the cable drum and with a lifting device for vertically lifting and lowering the pivot bearing, the cable drum being freely rotatably received by the pivot bearings in a raised position and in a lowered position Position of the pivot bearing, the shaft of the cable drum can be inserted into or removed from the pivot bearing.
  • Devices of this type (DE 88 07 859 U1) are used for processing the cable wound on the cable drum, by unwinding from the cable drum or for winding around another cable drum, on construction sites, during cable laying work or in the storage and shipping area.
  • the shaft of the cable drum in the pivot bearings can tilt due to the separate, independent lifting of the cable drum by the two lifting devices; it can also not be ruled out that the shaft of the cable drum will spring out of the pivot bearings together with the cable drum when the cable is unwound, in particular by motor winding, roll around in an uncontrolled manner and thereby cause damage; furthermore, one or both hydraulic lifting devices can fail, so that the cable drum is lowered to the ground and causes rolling damage on the ground; Finally, the rotating cable drum is freely accessible at all times, which means that injuries to the operating personnel cannot be ruled out.
  • the lifting device comprises a threaded spindle with two opposite threaded sections, on each of which a nut is prevented from rotating, which move axially in opposite directions when the spindle rotates, that the threaded spindle can be driven in rotation by a drive device, that rollers are mounted on the nuts, which engage on mutually mirror-symmetrical inclined surfaces in such a way that the inclined surfaces are raised or lowered when the nuts move in opposite directions, and that the pivot bearings are connected to the inclined surfaces via a linkage so that they are connected with the Inclined surfaces can be raised or lowered.
  • the device according to the invention enables the rotatably mounted cable drum to be safely raised, and it is ensured that the cable drum cannot be lowered unexpectedly.
  • the device is surrounded by a protective grille and are arranged on its cable withdrawal side essentially horizontally extending rods as cable overturn protection, so that the operating personnel can neither come into contact with the cable drum rotating during the unwinding process nor with the unwound cable and any risk of injury is thus excluded.
  • a device 1 for rotatably supporting a cable drum 2 comprises a frame 3, on which a linkage 4 is arranged so that it can be raised or lowered.
  • the linkage 4 comprises two carriages 5, which are guided vertically to the side of the cable drum 2, on each of which pairs of rotary bearings 6 are fastened at different heights, which serve to receive a cable drum shaft 7.
  • Fixed to the frame 3 is a threaded spindle 8, which comprises two opposing threaded sections 9, 10.
  • the threaded spindle 8 can be set in rotation by a suitable drive device 11, for example a hand crank 12 in FIG.
  • Rollers 15, 16 are each rotatably mounted on the nuts 13, 14, which engage on mutually mirror-symmetrical inclined surfaces 17, 18 of a projection 19 arranged on the linkage 4.
  • the two threaded sections 9, 10 of the threaded spindle 8 are rotatably connected to one another by a releasable coupling 20. In this way, the rollers 15 and 16 can be adjusted relative to the two inclined surfaces 17, 18 by individually turning the two threaded sections 9, 10 of the threaded spindle 8 when the coupling 20 is released.
  • Figure 3 shows a section along the line III-III in Fig. 2. It shows the guidance of the nuts 13, 14 with the rotatably mounted rollers 15, 16 on the frame 3, while these rollers on the inclined surfaces 17, 18 of the Attack projection 19.
  • the entire device is surrounded at least on the two sides, which run parallel to the end faces of the cable drum 2, and on the upper side by a protective grille 21 forming a housing.
  • a protective grille 21 On the cable withdrawal side of the housing, essentially horizontally extending rods 22 are arranged at different heights. In the event of a cable break, these rods serve as cable overturn protection. The cable end rotating due to the rotation of the cable drum 2 is braked by these rods 22.
  • the device operates as follows: First, depending on its size, a cable drum 2 is inserted into two pivot bearings 6 of suitable height. Then the threaded spindle 8 by the drive device 11, in Case of Figure 2 by rotating the hand crank 12, set in rotation. The two nuts 13, 14 move towards one another and the rollers 15, 16 rotatably mounted on the nuts roll on the two inclined surfaces 17, 18 of the projection 19 arranged on the linkage 4. As a result, the entire linkage 4 and with it the two carriages 5, on which the rotary bearings 6 are arranged, are raised together with the cable drum 2 or lowered when the threaded spindle 8 rotates in the opposite direction. The cable drum 2 is supported in a known manner by the shaft 7, which engages in the pivot bearing 6. Cable drums 2 of different sizes can be accommodated by rotary bearings 6, which are arranged in pairs on the carriage 5 at different heights.
  • the device 1 In addition to the uniform and easy lifting of cable drums 2, the device 1 also offers the possibility of particularly safe operation.
  • the cable drum 2 cannot lower itself due to a defect, ie without actuating the drive device 11, and thereby damage the operating personnel, since the device 1 due to the interaction of the threaded spindle 8 and its threaded sections 9, 10 with the nuts 13 arranged thereon , 14 acts against the displacement of these nuts 13, 14 by parallel and anti-parallel to the threaded spindle axis from the inclined surfaces 17, 18 on the nuts 13, 14 self-locking.
  • the operating personnel cannot come into contact with the rotating cable drum 2, since the device 1 is surrounded by a protective grille 21. And even in the event of a cable break, this can happen due to the rotational movement the cable end 2 hitting the cable end do no damage, since it gets caught in the rods 22 that run on the trigger side of the protective grille.
  • the coupling 20 can be released, the two threaded sections 9, 10 being rotated independently of one another and thereby the nuts with the rollers 15, 16 arranged on them on the inclined surfaces 17, 18 can be brought close together so that the rollers come to rest on the inclined surfaces 17, 18.
  • the fixed connection of the two threaded sections 9, 10 then produced by the coupling 20 ensures proper unrolling of the two rollers 15, 16 on the inclined surfaces 17, 18 and lifting of the shaft 7 in a always horizontal position.
  • the linkage 4 is divided into two linkage parts 24 and 25, which are positioned opposite the two end faces of the cable drum 2, in otherwise the same mode of operation as in FIGS. 1 and 2.
  • This offers the advantage that the coupling 20 can be dispensed with and the threaded spindle 8 can be made in one piece.
  • the adjustment of the two rollers 15, 16 to the inclined surfaces 17, 18 takes place by laterally displacing the two linkage parts 24, 25.
  • the device can also be driven by an electric motor 26 instead of a hand crank 12.
  • FIG. 4 also shows a smaller cable drum 2, the shaft 7 of which is received by the two lower pivot bearings 5.
  • quills 31 can be provided, which directly on both sides of the cable drum 2 into the bore provided for receiving the shaft 7 on the end faces of the cable drum 2 intervene.
  • the sleeves 31 are rotatably attached to parallelogram links 32.
  • the parallelogram handlebars 32 are actuated by an actuating rod 33 in such a way that they perform an arc-shaped movement along the arrow in FIG. 5 towards the cable drum 2 until the quills 31 grip the cable drum 2.
  • the parallelogram link 32 which carry the quill 31, are attached to the up and down linkage 4. Such parallelogram links 32 can consequently be used both in the device shown in FIGS. 1 and 2 and in the device shown in FIG. 4.
