Definitions

  • the invention relates to a cable crane in which a running gear supported on a carrying cable and movable on rollers is connected to a pulling cable and a return cable and the two cables can be driven by a drive station, the pulling cable being guided in the running gear and carrying a load-lifting tackle at its end, that can be lowered and pulled up when the undercarriage is at a standstill using the pull rope.
  • the cable crane is a transport device that is known in many embodiments. In a simple embodiment, it is composed of a drive station, a support cable on which a running gear is moved on rollers, and a pulling cable, one end of which is connected to the running gear and the other end of which is wound on a winch drum, which in the drive station is arranged.
  • a cable crane of this type it is necessary to arrange the drive station on the mountain side and, moreover, the support cable must be guided to its valley end with a considerable gradient. With this arrangement it is possible, on the one hand, to pull loads up to the drive station and, on the other hand, to lower them towards the valley end.
  • the traction cable is guided with at least one loop on a power transmission roller and then through a pair of feed rollers, the feed rollers being connected to the power transmission roller by a drive device such that the peripheral speed of the feed rollers is greater than that Circumferential speed of the power transmission roller is.
  • the cable crane shown in FIG. 1 has a drive station 2 set up at the valley end of a suspension cable.
  • the supporting cable 1 ends on a, mostly collapsible mast 3 and is held with anchors 4 both on the valley side and on the mountain side.
  • a suspension 5 is used to reduce the sag of the suspension cable 1.
  • a chassis 6 is supported on rollers 7, which is connected to the end of a traction cable 8.
  • the traction cable 8 is guided over the mountain-side end of the support cable 1 via guide rollers 10 and ends on a motor-driven cable winch in the drive station 2.
  • the end of a return cable 9 is also fastened to the chassis 6, which is also attached to a motor-driven cable winch in the drive station 2 ends.
  • a load 11 is attached to the chassis 6 and is towed against the drive station 2 in the direction of the arrow. Usually, however, it is desirable to let the suspension cable 1 run so high that the load can be moved as freely as possible. This contributes above all to the fact that the load towing gear can be pulled up to the chassis 6, as will be explained with reference to FIG. 2.
  • Fig. 2 the chassis 6 is partially shown with one of its castors 7 in a spatial representation.
  • the driving roller 7 is supported on the supporting cable 1.
  • a support 12 (shown somewhat distant from its fastening strips 13 in FIG. 2) is fastened to the chassis 6, between whose side plates 15 a shaft 14 is rotatably mounted.
  • a guide bushing 17 is held by means of support arms 16, through which the traction cable 8 is guided.
  • a reel 18, a power transmission roller 20 and a brake disc 21 are fastened on the rotatable shaft 14.
  • One end of the return rope 9 is wound on the reel 18, while the other end is wound on the winch in the drive station 2.
  • the pull rope 8 is guided with at least one loop 22 on the force transmission roller 20.
  • This is designed as a disc with a concave circumferential groove and can be used as a force transmission member if the frictional engagement is sufficiently secured by the wraps 22.
  • a sprocket 23 is attached to the roller 20, which is part of an enveloping drive 24, which is composed of the sprocket 23, a chain sprocket 25 and a chain 26 as an enveloping link.
  • the chain sprocket 25 is operatively connected to a roller 28, between which and a further roller 27 the traction cable 8 is guided.
  • the roller 28 is rotatably supported in a lower housing 29, while the upper roller 27 is mounted in a housing 30 which is guided in vertical guides (not shown) and pressed against the lower roller 28 by spring force (not shown), thereby simultaneously the Switzerlands'eil 8 is pinched.
  • the traction cable 8 is then guided over a deflection roller 31, then extends through a switching head 32 and ends at the load attachment harness 33, over which some load attachment hooks 34 are arranged.
  • the brake disc 21 is wound by a brake cable 35 in several turns and is fastened at one end to an angle lever 36, the brake cable 35 additionally having a tension spring 37.
  • the other end of the brake cable 35 is attached to one of the side shields 15.
  • the brake lever 36 is actuated from the switch head 32.
  • the lever 38 pivotably mounted on this is connected to the other arm of the angle lever 36 by means of a rope 39.
  • the power transmission roller 20 fastened on the shaft 14 has the task of making it possible to lower the traction cable 8 at every stop of the running gear 6. If the undercarriage 6 stops, the undercarriage is clamped to the supporting cable 1 by means of clamping jaws (not shown) by means of a hydraulic accumulator (not shown). Now the return cable 9 is unwound from the reel 18 by the drive station 2 (FIG. 1). With the clamping of the undercarriage 6 on the support cable 1, the brake cable 35 is also released. By unwinding the return rope 9, the force transmission roller 20 is rotated and the roller pair 27, 28 via the enveloping drive 24. Since the translation of the enveloping drive 24 is selected such that the roller pair 27, 28 unites Exercises train on the traction cable 8, the traction cable 8 is pulled by the rotation of the power transmission roller 20 and thereby the load hitch 33 is lowered.
  • the lowering of the pull cable 8 is therefore no longer dependent on a weight or on the arrangement of the pull cable 8, but is non-positively carried out by the force transmission roller 20. It is essential here that the frictional connection is ensured by the enveloping drive 24, which ensures that the rollers 27, 28 advance slightly.
  • the pull rope 8 is retrieved from the drive station 2. Since the pull rope is under the pull of the load, the reel 18 is also rotated via the force transmission roller 20 and the return rope is thereby wound up again.
  • the rollers 27, 28, which are positively coupled via a spur gear pair (not shown), are equipped with a freewheel so that they do not hinder the return of the traction cable 8.
  • the brake cable 35 is pulled by actuating the lever 38 and the brake is thus effective.
  • the clamping jaws on the supporting cable 1 are released and the undercarriage 6 can travel to another location, where the lowering of the pulling cable 8, the attachment of the load and the lifting of the load take place in the same way as described.
  • the advancing feed rollers 27, 28 are driven by a chain drive, but a toothed belt drive or a gear transmission could be used instead of the chain drive. It is only essential that the feed rollers 27, 28 advance somewhat relative to the force transmission roller 20 and form a frictional connection on the traction cable 8, by means of which the traction cable 8 is always held non-positively on the force transmission roller 20 when it is lowered.
