Description

Technical Field

[0001] The invention relates to the technical field of endless rope winches, in particular to a tensioning device for a traction shuttle car of an endless rope winch. Background Art

[0002] The endless rope winch traction shuttle car is an auxiliary transportation suitable for long distance, large tonnage, variable slope and large inclination conditions. In coal mines, metal mines and other industries, it is widely used for direct transportation of materials, equipment and hydraulic supports without relocation. The endless rope winch traction shuttle car is mainly composed of the endless rope winch, traction shuttle car, tensioning device and track system, among which the tensioning device is used to adjust the tension of the wire rope to ensure stable operation of the system.

[0003] The existing tensioning devices are mainly weight-type tensioning and hydraulic tensioning. The weight-type tensioning system uses the gravity of the weight itself to generate tensioning force on the traction rope of the traction rail car for tensioning. It is easy to be over-tensioned, resulting in accelerated wear of the wire rope. The main function of the hydraulic tensioning device is to ensure that the traction rope has a scientific and reasonable tension during operation when the traction rail car is in operation, to avoid the traction rope from loosening and slipping, and to prevent the traction rope from being always in an over-tensioned state when the equipment is running.

DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] Example: Figure 1and Figure 2 As shown, a tensioning device for an endless rope winch traction shuttle car comprises a frame 1, a rope storage drum 2 is arranged on one side of the top surface of the frame 1, and a tensioning mechanism is installed on the other side of the top surface of the frame 1;

[0031] Two support seats 3 are fixedly installed on the left side of the top surface of the frame 1 by bolts, and the rope storage drum 2 is rotatably installed on the two support seats 3 through a bearing seat. When the frame 1 moves on the track, the rope storage drum 2 rotates to store the wire rope.

[0032] The tensioning mechanism includes a T-shaped plate 4 fixedly mounted on the top surface of the frame 1, and the two horizontal arms of the T-shaped plate 4 are both provided with horizontal slide grooves 5, and the horizontal slide grooves 5 are internally slidably connected with a horizontal slider 6, and the vertical arm of the T-shaped plate 4 is provided with a vertical slide groove 7, and the vertical slide groove 7 is internally slidably connected with a vertical slider 8, and the front surfaces of the horizontal slider 6 and the vertical slider 8 are both fixedly connected with a mounting plate 9, and a tensioning wheel group 10 is installed on the front surface of the mounting plate 9, and the tensioning wheel group 10 includes a guide wheel 101 and a rope pressing wheel 102, and the guide wheel 101 and the rope pressing wheel 102 are both rotatably connected to the front surface of the mounting plate 9 through a rotating shaft;

[0033] A horizontal limit slide bar 11 and a vertical limit slide bar 36 are fixedly connected between the inner walls of the opposite sides of the horizontal slide groove 5 and the vertical slide groove 7, respectively, and the horizontal limit slide bar 11 is slidably connected to the horizontal slider 6, and the vertical limit slide bar 36 is slidably connected to the vertical slider 8. A tension spring is fixedly connected between the inner wall of the vertical slide groove 7 and the vertical slider 8, and the tension spring is sleeved on the vertical limit slide bar 36.

[0034] like Figure 6 As shown, the horizontal limit slide bar 11 can play a role in limiting and guiding the movement of the horizontal slider 6, and the vertical limit slide bar 36 can play a role in limiting and guiding the vertical slider 8.

[0035] A connecting rod 12 is horizontally fixedly connected to the upper back of the T-shaped plate 4, and the other end of the connecting rod 12 is fixedly connected to a limiting disc 13. An oblique support plate 14 is hingedly connected to the back of the horizontal slider 6, and a horizontal displacement rod 15 is hingedly connected to the other end of the oblique support plate 14, and the horizontal displacement rod 15 is slidably connected to the limiting disc 13;

[0036] like Figure 4 As shown, when the endless rope winch is running to pull the shuttle car, the wire rope becomes loose. Since the pressure of the wire rope on the tensioning wheel group 10 disappears, the tensioning spring will stretch, further driving the vertical slider 8 to move downward along the vertical limit slide bar 36. At the same time, the horizontal displacement rod 15 moves toward the T-plate 4, further driving the other end of the inclined support plate 14 to move outward, and the horizontal slider 6 moves outward along the horizontal limit slide bar 11, thereby realizing the rapid tensioning of the wire rope after it is relaxed.

[0037] When the endless rope winch is running and the shuttle car is towing, the wire rope is over-tightened, that is, the pressure of the wire rope on the tensioning wheel group 10 is too large, the tensioning spring will be compressed, and the vertical slider 8 will move upward along the vertical limit slide bar 36 under the pressure of the wire rope. At the same time, the horizontal displacement rod 15 moves away from the T-plate 4, further driving the other end of the inclined support plate 14 to move inward, and the horizontal slider 6 moves inward along the horizontal limit slide bar 11, avoiding over-tensioning due to excessive tension.

[0038] An adjusting mechanism matched with the tensioning mechanism is also installed on the other side of the top surface of the frame 1, and the adjusting mechanism includes a straight plate 16, and a first rotating rod 17 is rotatably connected to the upper part of the side of the straight plate 16, and the end of the first rotating rod 17 is rotatably connected to the side of the limiting disc 13, and an adjusting disc 18 is coaxially fixedly connected to the outer wall of the first rotating rod 17, and a plurality of slideways 19 are provided on the side of the adjusting disc 18 with the first rotating rod 17 as the reference axis. A counterweight slider 20 is slidably connected inside the slideway 19, and a return spring is fixedly connected between the counterweight slider 20 and the inner wall of the slideway 19, and an oblique connecting plate 21 is hinged on the side of the counterweight slider 20, and a movable disc 22 is also slidably sleeved on the outer wall of the first rotating rod 17, and the other end of the oblique connecting plate 21 is hinged on the side of the movable disc 22, and an annular sliding groove is provided on the other side of the movable disc 22. Since the end of the horizontal displacement rod 15 is slidably connected to the annular sliding groove, the horizontal displacement rod 15 will not limit the rotation of the movable disc 22;

[0039] A first limiting slide bar 23 is fixedly connected to the outer wall of the first rotating rod 17 . The first limiting slide bar 23 is slidably connected to the movable disc 22 , and the first limiting slide bar 23 is used to limit the relative rotation between the movable disc 22 and the first rotating rod 17 .

[0040] A second limiting slide bar 27 is fixedly connected to the outer wall of the first rotating rod 17, and a third limiting slide bar 28 is fixedly connected to the outer wall of the second rotating rod 25. The second limiting slide bar 27 and the third limiting slide bar 28 are both slidably connected to the transmission disk 37, and the second limiting slide bar 27 and the third limiting slide bar 28 are used to limit the relative rotation between the transmission disk 37 and the first rotating rod 17 and the second rotating rod 25.

[0041] like Figure 4 and Figure 5 As shown, the movement of the horizontal displacement rod 15 is controlled by the adjustment mechanism. The specific process is that the first rotating rod 17 rotates to drive the adjustment disc 18 to rotate. Since the counterweight slider 20 is in the slideway 19 on the adjustment disc 18, during the rotation of the adjustment disc 18, the counterweight slider 20 will move outward under the action of centrifugal force, and the inclination angle of the inclined plate 21 will change. The movable disc 22 is further driven by the inclined plate 21 to slide on the first rotating rod 17 toward the T-plate 4, and the horizontal displacement rod 15 will move synchronously therewith.

[0042] The other side of the top surface of the frame 1 is fixedly connected to a triangular plate 24, and the upper part of the side surface of the triangular plate 24 is rotatably connected to a second rotating rod 25. Two circular plates 26 are fixedly connected to the outer walls of the first rotating rod 17 and the outer walls of the second rotating rod 25. Two mutually symmetrical transmission plates 37 are also slidably sleeved on the outer walls of the first rotating rod 17 and the outer walls of the second rotating rod 25. The inner sides of the transmission plates 37 are chamfered, and the transmission plates 37 are located between the two circular plates 26. The outer walls of the first rotating rod 17 and the second rotating rod 25 located between the circular plates 26 and the transmission plates 37 are sleeved with return springs.

[0043] A limit slide groove 29 is provided on the side of the straight plate 16, and a limit slider 30 is slidably connected inside the limit slide groove 29. One side of the limit slider 30 is rotatably connected to an intermediate transmission plate 31 through a rotating shaft. Both sides of the intermediate transmission plate 31 are provided with chamfers with the same chamfer angle as the transmission plate 37, and the chamfered inclined surface of the intermediate transmission plate 31 contacts the chamfered inclined surface of the transmission plate 37. A reverse movement mechanism 32 is installed between the other side of the limit slider 30 and the side of the vertical slider 8. It needs to be explained that the transmission between the transmission plate 37 and the intermediate transmission plate 31 is transmitted by the friction force of the contact surface. For this purpose, materials with a high friction coefficient can be selected to manufacture the transmission plate 37 and the intermediate transmission plate 31, and the return spring provides the contact surface pressure between the transmission plate 37 and the intermediate transmission plate 31.

[0044] A guide rod 33 is fixedly connected between opposite sides of the limiting sliding groove 29 , and the guide rod 33 is slidably connected to the limiting sliding block 30 .

[0045] The reverse moving mechanism 32 includes a support plate 321, two L-shaped plates 322 and a spur gear 323. The support plate 321 is fixedly connected to the top surface of the frame 1, and the upper part of the side of the support plate 321 is rotatably connected to the spur gear 323. The two L-shaped plates 322 are respectively fixedly connected to the sides of the vertical slider 8 and the limit slider 30. The outer side of the L-shaped plate 322 is fixedly connected to a rack, and the rack of the L-shaped plate 322 is meshed with the spur gear 323.

[0046] One end of the rotating shaft of the rope storage drum 2 is coaxially fixedly connected to a driving belt pulley 34, and one end of the second rotating rod 25 extending to the outside of the triangular plate 24 is coaxially fixedly connected to a driven belt pulley 35, and the driving belt pulley 34 and the driven belt pulley 35 are transmitted through a transmission belt. The rope storage drum 2 drives the second rotating rod 25 to rotate through the driving belt pulley 34, the driven belt pulley 35 and the transmission belt.

[0047] like Figure 3As shown, when the endless rope winch is running to pull the shuttle car, the wire rope becomes loose. Since the pressure of the wire rope on the tensioning wheel group 10 disappears, the tensioning spring will stretch, further driving the vertical slider 8 to move downward along the vertical limit slider 36, and the vertical slider 8 drives one of the L-shaped plates 322 to move downward. Under the action of the rack and the spur gear 323, the other L-shaped plate 322 drives the limit slider 30 to move upward along the guide rod 33, and the intermediate transmission plate 31 moves upward accordingly. At this time, the transmission ratio between the transmission plate 37 on the second rotating rod 25 and the intermediate transmission plate 31 is increased, and the intermediate transmission plate 31 and the first rotating rod 1 7, the transmission plate 37 on the upper rotating rod 37 will also be raised, so the transmission ratio between the second rotating rod 25 and the first rotating rod 17 is improved, which further leads to the increase of the centrifugal force of the counterweight slider 20. The counterweight slider 20 will move outward under the action of the centrifugal force, and the inclination angle of the inclined connecting plate 21 will change. The movable disc 22 will be further driven by the inclined connecting plate 21 to slide on the first rotating rod 17 toward the T-shaped plate 4, and the horizontal displacement rod 15 will move synchronously therewith, further driving the other end of the inclined support plate 14 to move outward, and the horizontal slider 6 will move outward along the horizontal limit slider 11, thereby realizing the rapid tightening of the wire rope after relaxation.

[0048] like Figure 3 As shown, when the endless rope winch is running and the shuttle car is towing, the wire rope is over-tightened, that is, the wire rope exerts too much pressure on the tensioning wheel group 10, the tensioning spring will be compressed, and the vertical slider 8 will move upward along the vertical limit slide bar 36 under the pressure of the wire rope, and the vertical slider 8 will drive one of the L-shaped plates 322 to move upward. Under the action of the rack and the spur gear 323, the other L-shaped plate 322 drives the limit slider 30 to move downward along the guide rod 33, and the intermediate transmission plate 31 moves downward accordingly. At this time, the transmission ratio between the transmission plate 37 on the second rotating rod 25 and the intermediate transmission plate 31 will be reduced, and the intermediate transmission plate 31 will be closer to the first rotating rod 25. The transmission disk 37 on the first rotating rod 17 will also be lowered, so the transmission ratio between the second rotating rod 25 and the first rotating rod 17 is reduced, which further leads to a decrease in the centrifugal force of the counterweight slider 20. The counterweight slider 20 will move inward under the action of the centrifugal force, and the inclination angle of the inclined connecting plate 21 will change. The movable disc 22 will be further driven by the inclined connecting plate 21 to slide on the first rotating rod 17 away from the T-shaped plate 4. The horizontal displacement rod 15 will move synchronously therewith, further driving the other end of the inclined support plate 14 to move inward, and the horizontal slider 6 will move inward along the horizontal limit slide bar 11, thereby avoiding over-tensioning.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
