Definitions

  • the invention relates to a conveying device on cable conveying systems for driving at least one endless cable which is guided over a traction sheave and partially wrapped around it, with endless outer cables guided around the conveying rope and the traction sheave, wrapping the traction sheave partially under tension and exerting an increased frictional connection between the conveying rope and the traction sheave.
  • the object of the invention is to provide a conveyor device which has a small construction volume and a low weight even with high tensile forces, only generates the pretension required for the prevailing tensile force by self-pressing, exposes the ropes to a few bending changes and also avoids the disadvantages of multiple wrapping.
  • the solution according to the invention is based on a generic conveyor device on cable conveyor systems for driving conveyor cables, and it consists in that the conveyor cable is guided around a non-driven deflection pulley mounted at an axial distance B from the traction sheave and the endless outer cables are parallel to the traction sheave on both sides and Deflection pulley mounted guide pulleys are guided, to which the traction sheave is variable in distance is stored at an axial distance A.
  • the deflection pulley which is supported at an axial distance B from the traction sheave, serves to deflect the conveyor cable.
  • the endless outer ropes are guided around the traction sheave, which is variable in the distance between the axes A to the deflection pulleys.
  • This configuration ensures that when the conveyor cable is loaded with a tensile force which acts on the deflection pulley and the traction sheave mounted with the center distance B, the center distance A seeks to increase and the pretensioning of the endless outer ropes thus increases with increasing tractive force, as a result of which the frictional connection between the conveyor cable and the traction sheave is increased by self-pressing to such an extent that it is adapted to the momentary tensile force and is necessary to prevent the conveyor cable from slipping on the traction sheave.
  • An advantageous embodiment consists in that the deflection rollers are mounted with different axes at axial distances A1, A2 to the drive pulley. This design makes it possible for the endless outer ropes to have different lengths.
  • a first preferred embodiment is that the axis of the deflection pulley lies in the area of the center distance A between the traction sheave and the deflection pulleys. and another preferred embodiment can be that the axes of the deflection rollers lie in the region of the center distance B between the traction sheave and the deflection sheave.
  • a second preferred embodiment can be that the axis of the deflection disc, the axis of the traction sheave and the axes of the deflection rollers lie in one plane.
  • the axes of the traction sheave, the deflection sheave and the deflection rollers are arranged next to one another in exactly one direction, which can be particularly advantageous for the forces which develop in the direction of the center distances.
  • the deflection pulley and the traction sheave are mounted by means of bearings in bearing housings which are connected to one another by means of a spacing connecting element.
  • the spacing connecting element serves to limit the shortest center distance B between the deflection pulley and traction sheave, as a result of which the pulling force exerted on the deflection pulley and aiming to shorten the center distance B, exerted by the load end of the conveyor cable, by means of the spacing connecting element delimiting the center distance B on the traction sheave, which is mounted at a variable distance in the center distance A from the deflection pulleys, in a way to increase the center distance A , the tension of the endless outer ropes increases.
  • An alternative embodiment can consist in that the spacing connecting element is formed from a fixed connection of the bearing housing of the deflection pulley with the bearing housing of the traction sheave or from a common bearing housing of deflection pulley and traction sheave.
  • the conveyor device is designed so that the deflection rollers are mounted by means of bearings in a spring-loaded holder which can be displaced by means of a straight guide relative to the bearing housing of the deflection pulley and / or the bearing housing of the traction sheave is.
  • the straight guide serving as a torque support prevents the axis of the traction sheave from laterally deviating with respect to the axis of the deflection rollers under load.
  • the straight guide can expediently be designed as a round guide.
  • the straight guide can also consist of another device, such as a guide pin, which prevents the axis of the traction sheave from tilting relative to the axis of the deflection rollers.
  • the spring tension creates a pretension of the endless outer ropes even without a tensile force acting on the conveyor rope.
  • the bracket can be connected to one or more attachment points to a load-bearing suspension to attach the conveyor.
  • An additional preferred embodiment of the conveyor device according to the invention is that the spring tension is directed to an increase in the center distance A between the traction sheave and the deflection rollers and is generated by compression springs or tension springs. As a result, the endless outer ropes are pretensioned even without a tensile force acting on the conveyor rope.
  • the conveying device is further configured such that the pretension of the compression springs or the tension springs can be adjusted by means of adjusting elements.
  • the pretensioning of the endless outer ropes can be adjusted.
  • Another advantage of this training is the fact that it facilitates or enables the assembly of the conveyor device and the replacement of the endless outer cables.
  • a practical training can be that the adjusting elements are set screws and the compression springs or tension springs are coil or disc springs.
  • the guide of the conveyor cable on the traction sheave is shaped as a radial groove with wedge-shaped flanks adjoining on both sides.
  • the conveyor cable is guided securely in the radius groove, and the wedge-shaped flanks can be designed so that the endless outer cables are protected in a manner that protects the cable come to rest non-positively on the conveyor cable.
  • a further expedient embodiment of the conveying device is that one or two adjustable eccentric disks arranged on the support of the deflection rollers can adjust one or both distances A1, A2 between the drive pulley and the two deflection rollers independently of one another.
  • This configuration allows different lengths of the endless outer ropes to be compensated for when the conveyor device is installed, so that both act on the conveyor rope with the same pretension.
  • the adjustment of the eccentric discs can expediently take place in that they can be adjusted by means of a clamping tool engaging in mounting bushings and can be locked by means of fastening elements.
  • the conveyor device according to the invention can be designed so that a hand crank or a motor drive can be connected to the shaft used to support the traction sheave.
  • a gear preferably a planetary reduction gear or, between the traction sheave and the drive a spur gear is switched on or that the gear can be driven by means of an oil motor.
  • An advantageous embodiment consists in the fact that the traction sheave, the motor drive or the transmission can be braked by means of a holding brake, since the conveyor cable can thereby be ascertained without further application of force or can be released from the conveying device in a controlled manner.
  • a less space-consuming construction of the conveying direction can be made possible by the fact that the gear is installed in the traction sheave. This can also be favorable for a high power delivery of the conveyor.
  • a conveyor device can serve as a lifting, pulling or conveying unit for lifting, lowering, recovery or similar conveyor systems for loads, such as e.g. for goods and passenger lifts, cranes, cable cars, cable winches, pulling devices for external and self-mining operations, for example for vehicle installation, for baskets that can be lowered on the outside of high-rise buildings, in forestry operations, for the fire service or in construction, and in general for all applications, where loads are lifted, pulled or conveyed.
  • loads such as e.g. for goods and passenger lifts, cranes, cable cars, cable winches, pulling devices for external and self-mining operations, for example for vehicle installation, for baskets that can be lowered on the outside of high-rise buildings, in forestry operations, for the fire service or in construction, and in general for all applications, where loads are lifted, pulled or conveyed.
  • the design of the conveyor device according to the invention ensures that the conveyor device has a small construction volume and a low weight even with high tensile forces and the required pretensioning of the endless outer ropes, which can be increased by a usual safety factor for the current load on the conveyor rope, in rope-friendly and safe way is generated by self-pressing.
  • Further advantages of the conveying device according to the invention can be seen in the fact that it can exert a constant lifting and pulling force, the conveying rope can be conveyed at a constant rope speed, the rope winding and the frictional engagement are kept constant and the loose end of the rope can be stored without load.
  • the load-free rope storage which avoids winding problems, has the further advantage that the length of the conveyor rope can be of unlimited length.
  • Fig. 1 the basic operation of the conveyor device according to the invention is shown.
  • the load 38 exerts a tensile force on the load end 36 of the conveyor cable 1, which is guided around the deflection pulley 2 and the traction sheave 3 and exits the conveyor device with its loose end 37.
  • the deflection pulley 2 and the traction sheave 3 are mounted with the center distance B from one another.
  • the deflection rollers 5, 6 are at an attachment point 39 attached to a fixed, load-bearing suspension point.
  • the endless outer ropes 4 are guided around the deflection rollers 5, 6 and the traction sheave 3, the conveyor cable 1 resting on the traction sheave 3 between the endless outer ropes 4 and the traction sheave 3.
  • the endless outer ropes 4 are pretensioned even without an active load 38.
  • the pulling force exerted by the load 38 on the conveyor cable 1 now causes the deflecting disc 2, which is variable in the distance to the deflecting rollers 5, 6, and the deflecting disc 2, which is mounted in the center distance B for this purpose, connected by means of the spacing and the shortest center distance B connecting element 7, in which distance-variable center distance A to the deflection rollers 5, 6 mounted traction sheave 3 together move away from the deflection rollers 5, 6.
  • the deflection pulley 2 and the traction sheave 3 are arranged next to one another in approximately the same direction, because then the force effects on the center distances A, B come into play best.
  • FIG. 2 shows the same as FIG. 1, and FIGS. 3 to 5 show, for comparison, other possible arrangements that work according to the same principle that effects self-pressing.
  • the basic arrangement shown in Fig. 3 differs from that in Fig. 2 in that the compression spring 21 does not act between the deflection rollers 5, 6 and the drive pulley 3, but between the deflection rollers 5, 6 and the deflection pulley 2. Because of the spacing Connecting element 7, the shortest Center distance B between the deflection pulley 2 and the traction sheave 3 is limited, but the pressure force exerted by the compression spring also has an increasing effect on the axis distance A between the deflection rollers 5, 6 and the traction sheave 3.
  • FIGS. 4 shows an arrangement in which, in contrast to FIGS. 2 and 3, the axis 10 of the deflection sheave 2 is not arranged in the region of the center distance A between the deflection sheaves 5, 6 and the drive sheave 3, but the deflection sheaves 5, 6 are arranged in the region of the center distance B between the deflection disk 2 and the drive disk 3.
  • the deflection rollers 5, 6 are again fastened to an attachment point 39 at a fixed, load-bearing point.
  • the spacing connecting element 7 delimits the shortest center distance B between the deflection sheave 2, which is mounted variable in distance to the deflection rollers 5, 6, and the traction sheave 3, which is also shiftable in the distance between the axes A, with respect to the deflection rollers 5, 6.
  • Compression spring 21 brings about the pre-tensioning of the endless outer ropes 4 without load 38.
  • the deflection pulley 2 moves towards the deflection pulleys 5, 6 and the traction sheave 3 away from them.
  • Fig. 5 shows a further basic arrangement, which differs from that in Fig. 4 in that instead of the compression spring 21 between the guide rollers 5, 6 and the drive pulley 3, a tension spring 22 is arranged between the guide plate 2 and the guide rollers 5, 6 .
  • Fig. 6 shows an embodiment of the pulling device according to the principle of Fig. 4 in a side view.
  • the deflection rollers 5, 6 can be adjusted separately from one another in their axial distances A1 and A2 from the conveyor disc 3 by means of eccentric disks 29, to compensate for different lengths of the endless outer ropes 4, for example when assembling the conveyor device or when replacing worn endless outer ropes 4, or to be able to retension them as they age.
  • the eccentric discs 29 are adjustable by means of a clamping tool engaging in the mounting bushes 30 and can be locked by means of the fastening elements 31.
  • the spacing connecting element 7 acts between the bearing housing 18 of the deflection pulley 2 and the bearing housing 19 of the traction sheave 3.
  • a common bearing housing defining a fixed center distance B between the deflection pulley 2 and traction sheave 3 can be formed.
  • a cutout 40 is arranged, which allows the movement of the shaft 27 of the deflection pulley 2 when the conveyor device is loaded or when the endless outer cables 4 are elongated due to aging.
  • the guide pin 9 prevents the bearing housing 19 of the traction sheave 3 from rotating relative to the holder 20.
  • the traction sheave 3 can be driven by means of the oil motor 34 serving as drive 32 and a gear 33 and the holding brake 35 can be braked.
  • Fig. 7 the conveyor device according to Fig. 6 is shown in front view, in contrast to Fig. 6, the deflection rollers 5, 6 in the same-axis storage, as is the case with identical lengths of the endless outer cables 4, are shown, so that the center distances A1 and A2 to the traction sheave 3 are both equal to A.
  • the torque support 8 designed as a round guide prevents the traction sheave 3 from evading laterally when the conveyor cable 1 is loaded.
  • the axis 10 of the deflection pulley 2, the axis 11 of the traction sheave 3 and the axes 12, 13 of the deflection rollers 5, 6 are not exactly next to one another here in one direction arranged, but the axis 11 of the traction sheave 3 is offset slightly to the side, which simplifies the cable guide in the conveyor device on the loose end 37 of the conveyor cable 1.
  • the force of the compression springs 21 can be adjusted by means of the adjusting elements 23. By means of the end stops 24, which are designed as bolts, of the adjusting elements 23, the force of the compression springs 21 can be easily adjusted to the value provided in the factory when the conveyor device is installed.
  • FIG. 8 shows in a partial cross section through the traction sheave 3 how the guidance of the conveyor cable 1 on the traction sheave is shaped as a radius groove 25 with wedge-shaped flanks 26 adjoining on both sides, which guide the endless outer cables 4.
