Definitions

  • the invention relates to a cable pulling device with a single, driven traction sheave and with a continuous rope, the load strand of which wraps around the traction sheave and at the end of the wrapping of two
  • Circumferential direction one behind the other on a tiltable roller carrier pressure rollers is pressed into the wedge-shaped cable groove of the traction sheave and its lostrum runs behind the pressure rollers next to the load strand through a guide device from the cable groove.
  • a cable pulling device of this type is known (CH-PS-636 325), in which the roller carrier with the pressure rollers is mounted on a rocker arm, which in turn carries control rollers, between which the load strand of the rope passes under deflection and strives for its tension, to pivot the rocker arm and press the pressure rollers against the rope running in the rope groove of the traction sheave.
  • the object of the invention is to provide a cable pulling device of the type explained in the introduction, into which the cable can be easily inserted and in which it is guided very gently and without strong bends, in particular without counter-bends during the entry and exit, and on the same Place the traction sheave can run in and out in parallel tangential planes.
  • the traction sheave has a tread on its outer circumference in addition to the cable groove and that the guide device is provided with an inlet guide arranged tangentially to the cable groove for the load strand and with a side ramp for the lost strand, via which the Lost rope of the rope is directed onto the tread of the traction sheave.
  • This configuration has the advantage that neither the load strand nor the lost strand undergoes a counter-bend in the cable pulling device or is bent more than on the traction sheave itself.
  • the lost strand which is at least stressed by its own weight, can open over the edge of the traction sheave the tread continuously, vertically downwards, so that the space requirement is very low.
  • the rope groove advantageously has a cross section which is asymmetrical with respect to the traction sheave plane, and the flank of the rope groove adjacent to the tread has a greater inclination than the flank facing away from the tread.
  • the edge between the tread and the adjacent rope groove flank can also be rounded.
  • the guide device advantageously has a tongue in the pulling direction of the traction sheave in front of the lateral ramp, the tongue tip of which extends to the bottom of the cable groove and which forms a radial ramp rising in the circumferential direction of the traction sheave.
  • the tip of the tongue lifts the tip of the rope when the rope is pushed in and guides it out of the groove until it is guided over the side ramp onto the running surface of the traction sheave.
  • the tongue has the task of removing dirt or other foreign matter from the bottom of the rope groove, thereby keeping the rope groove clear throughout the entire depth.
  • the guide device In order to guide the Lostrum after it runs out of the rope groove into an outlet plane parallel to the incoming load strand, the guide device has a curved first guide surface for the back of the Lostrum above the running surface of the traction sheave, which begins in the area of the tongue and ends at a drain pipe .
  • the inlet guide for the load strand is expediently designed as an inlet channel to which a second guide surface for the load strand connects, which lies opposite the cable groove of the traction sheave and to which the circumferential cover of the cable groove common in traction sheave drives of the present type is connected.
  • the pressure rollers in the cable drive according to the invention have a narrower radial projection, which can be inserted into the cable groove, on their circumferential surface, and the roller carrier is mounted with the pressure rollers on a spring-loaded lever, which can execute a large swiveling path and with a sufficient length relatively low spring load on the pressure rollers a sufficiently high contact pressure on the rope in the Can exercise rope groove.
  • the pressure rollers have a radially recessed shoulder on at least one side of their radial projection, with which the pressure rollers can be supported on the outer circumference, in particular on the running surface of the traction sheave.
  • This shoulder which does not hinder the immersion of the radial projection of the pressure rollers when they press the rope into the wedge groove of the traction sheave during operation, has proven to be particularly useful when inserting the rope into the cable pulling device.
  • the spring-loaded lever has a stop on which it is supported under spring loading before the rope is inserted such that the distance of the radial projection of the one pressure roller from the bottom of the rope groove of the traction sheave is approximately the same as the thickness of the rope tip, while the second pressure roller with it Shoulder rests on the outer circumference of the traction sheave. Since the rope tip is usually somewhat thinner than the nominal cross-section of the rope, the first pressure roller climbs slightly onto the rope when the rope tip is pushed in, the spring-loaded lever being slightly raised.
  • the first pressure roller When the rope is advanced further, the first pressure roller then exerts a slight clamping pressure on the rope in the rope groove, which is sufficient to push the rope under the second pressure roller by rotating the traction sheave, which thereby raises the lever against the action of its pressure spring, whereby the predetermined contact pressure is reached.
  • the pressure rollers exert a considerable contact pressure on the rope under the action of the spring-loaded lever, the contact pressure of the first roller when threading is so low thanks to the arrangement according to the invention that the rope tip is slightly automatic, i.e. without venting the pressure device, can be inserted first under the first and then under the second pressure roller.
  • An easy and automatic insertion of the rope is important for rope pulling devices of the present type, since these rope pulling devices are often used for lifting and lowering work platforms on different construction sites in frequently changing locations, so that the rope often has to be pulled out and re-threaded under difficult conditions .
  • the rope in the operation of the side pulling device according to the invention is subject to only slight wear, since it is only bent with the large radius of curvature of the traction sheave and runs straight into the cable groove and can roll on the running surface of the traction sheave before it pulls the cable pulling device leaves again.
  • the cable pull device as a lifting device for working platforms with a high driving height and high weight of the then very long raffle, no high frictional forces occur in the guide device, since the raffle automatically climbs onto and over the running surface of the traction sheave via the more inclined flank flank the tread runs off without sliding on solid housing parts of the cable pull device.
  • 10 denotes a cable pulling device which works with a continuous cable 11, which is preferably a wire cable, on the load strand 12 of which the load to be lifted or lowered is suspended, while the lost strand 13 of the cable 11 is load-free.
  • the housing 14 of the cable pulling device 10 can be suspended at a fixed point, in which case the load hanging on the load strand 12 is then pulled or relaxed with the load strand.
  • the load strand 12 can also be fixed at a fixed point, while the housing 14 of the cable pulling device is firmly connected to a working platform hanging on the cable, which represents the load and with which the cable pulling device moves up and down on the cable.
  • pulling devices of the type according to the invention are preferably used, the lostrum 13 running out of the cable pulling device generally hanging down freely, but can also be weighted down at the lower end.
  • a traction sheave 15 with ball bearings 16 is rotatably mounted in the housing 14, around which the cable 11 rotates.
  • the traction sheave 15 has an internal toothing 17, in which a pinion 18 engages, which is driven in rotation by a traction sheave drive, not shown here.
  • the traction sheave 15 has an asymmetrical, wedge-shaped cable groove 19, which is shown larger in FIG. 7.
  • the traction sheave 15 is provided on its outer circumference 20 with a tread 21 which is approximately perpendicular to the traction sheave plane 22 and the purpose of which will be explained further below.
  • flank 23 of the cable groove 19 adjacent to the tread 21 has a greater inclination to the traction sheave plane 22 than the flank 24 facing away from the tread 21.
  • This flank 24 facing away can run parallel to the traction sheave plane 22.
  • Their angle of inclination a to the traction sheave plane 22 is smaller than the angle of inclination of the opposite flank 23.
  • the edge 25 between the tread 21 and the cable groove flank 23 adjacent to it is provided with a greater rounding and the cable groove base 26 is rounded.
  • the outer circumference of the traction sheave 15 has a circumferential shoulder 27 into which a circumferential seal 28 accommodated in the housing 14 engages, with which the traction sheave 15 is sealed against the gear oil in which the drive gear of the traction sheave 15 runs .
  • the cable 11 is pressed at the end of its looping path by a first pressure roller 29 and a second pressure roller 30 into the cable groove 19 of the traction sheave 15.
  • the pressure rollers 29 and 30 are freely rotatably mounted directly one behind the other on a roller carrier 31, which in turn is tiltably mounted on a spring-loaded lever 32.
  • the lever 32 is pivotally mounted at its one end 32a on the left in FIG. 1 in the housing 14 and articulated at its other end 32b on the right in FIG. 1 to a pull rod 33 which penetrates a stop plate 34 fastened to the housing 14 and on it lower, free end 34a carries an abutment plate 35.
  • the pull rod 33 is surrounded by a strong compression spring 36, which is supported on the one hand on the abutment plate 35 and on the other hand on the underside of the stop plate 34 and the pretensioning thereof can be adjusted by adjusting the abutment plate 35.
  • each pressure roller 29 in the central region of its circumferential surface 37 has a narrow radial projection 38, the width and lateral boundary surfaces of which are adapted to the shape of the cable groove 19, so that this radial projection can enter the cable groove.
  • each pressure roller 29 or 30 has radially recessed shoulders 39 laterally next to the radial projection 38, with which the pressure rollers 29 and 30 can be supported on the outer circumference 20 of the traction sheave 15 or on the tread 21 when their radial projection 38 is completely in the cable groove 19 of the traction sheave 15 is immersed.
  • the lever 32 which consists of two parts 32 'and 32 "which enclose the roller carrier 31 between them, is supported with its right end 32b on the stop plate 34 when there is no rope in the cable pulling device. In this position, the Pressure rollers 29 and 30 with their radial projections 38 into the cable groove 19, but have so much play with their shoulders 39 to the tread 21 of the traction sheave 15 that the roller carrier 31 can carry out slight tilting movements about its tilt axis 40.
  • the roller carrier 31 has the position shown in FIG 1 assumes the position shown, in which the second pressure roller 30 is supported with its shoulder 39 on the running surface 21 of the traction sheave 15, the circumferential surface 37 of the radial projection 38 of the first pressure roller 29 has a distance a from the cable groove base 26 of the cable groove 19, which is just as large is like the thickness d of the rope tip 41 of the rope 11.
  • the tip of the wire rope used with the rope pulling device according to the invention is somewhat thinner than the control diameter of the rope.
  • the cable 11 When the cable 11 is pushed in in the direction of the arrow 42, the cable runs around the traction sheave 15, which in this case rotates in the direction of the arrow 43.
  • the rope tip 41 then comes under the first pressure roller 29 and lifts it up a little while it runs onto the rope which has been pushed further and which becomes thicker up to its normal cross section.
  • the roller carrier 31 pivots on the one hand about the axis of rotation of the second pressure roller 30 and on the other hand about the tilt axis 40 in FIG. 1 in a clockwise direction, the tilt axis 40 pivoting the lever 32 counterclockwise about its pivot axis 44 and counter to the action of the spring 36 by one small amount stands out from the stop 34.
  • the cable tip 41 passes under the peripheral surface 37 of the radial projection 38 of the second pressure roller 30.
  • the peripheral surface 37 of this second pressure roller 30 is now at a distance from the bottom of the cable groove that is less than the thickness d of the rope tip 41, but nevertheless the second pressure roller 30 willingly climbs onto the rope tip 41 and then onto the subsequent rope with a regular cross-section, since the first pressure roller 29, which is now already loaded by the spring 36 via the lever 32, one Applies contact pressure to the rope and presses it so firmly into the rope groove 19 that the rope tip 41 is pushed under the second pressure roller 30 with considerable circumferential force.
