Description

Technical Field

[0001] The utility model relates to the technical field of coal mines, in particular to an endless rope winch. Background Art

[0002] The endless rope winch is a common rail continuous transportation equipment pulled by wire rope in the underground tunnel of coal mine. When the endless rope winch is in use, the motor is used to drive the take-up wheel to rotate, and then the wire rope is wound around the take-up wheel, and then the wire rope is used to drive the shuttle car to move. Although the motor has a self-locking function when driving the take-up wheel to rotate, in actual use, the wire rope will inevitably pull the take-up wheel sometimes. Although this force will not drive the take-up wheel to rotate, there will be a tendency to drive the take-up wheel to rotate, which will act on the motor that limits the rotation of the take-up wheel, which is not conducive to the stability of the motor when locking the take-up wheel. In the long run, it will destroy the self-locking function of the motor and undoubtedly reduce the operating efficiency of the endless rope winch. Utility Model Content

[0003] The utility model aims to solve the defect that the endless rope winch in the prior art has no additional locking mechanism on the take-up wheel when the endless rope winch is in use, and proposes an endless rope winch.

[0005] An infinite rope winch is designed, including a base, a take-up wheel is rotatably provided on the base, a motor and a wire rope are fixed on the take-up wheel, the motor is fixed on the base, a locking mechanism is provided on the take-up wheel, the locking mechanism includes a plurality of holes, the plurality of holes are evenly symmetrically and coaxially arranged on the take-up wheel, a movable frame is symmetrically provided on both sides of the take-up wheel, a plurality of insertion columns are fixed on the movable frame, the plurality of insertion columns are respectively inserted in the plurality of holes, an adjustment mechanism is commonly fixed on the two movable frames, and the adjustment mechanism is fixed on the base.

[0006] Preferably, the adjustment mechanism comprises a plurality of fixed columns, the plurality of fixed columns are all fixed on the base, a top plate is commonly fixed on the plurality of fixed columns, an adjustment component is fixed on the top plate, and the adjustment component is fixed on the two movable frames.

[0007] Preferably, the adjustment component includes a dual-axis motor, which is fixed to the top plate, and threaded rods are fixed on the two output shafts of the dual-axis motor, and first fixed plates are rotatably provided on the two threaded rods, and the two first fixed plates are fixed to the top plate, and sleeves are threadedly mounted on the two threaded rods, and fixed rods are fixed on the two sleeves, and the two fixed rods are respectively fixed on the two movable frames, and the two movable frames are provided with limit assemblies, and each limit assembly is fixed on the two fixed columns.

[0008] Preferably, the limiting assembly comprises a second fixing plate, the second fixing plate is fixed on the two fixing columns, a limiting rod is slidably penetrated on the second fixing plate, and the limiting rod is fixed on the moving frame.

[0009] Preferably, the limiting rod is made of a self-lubricating rod.

[0010] The infinite rope winch proposed by the utility model has the beneficial effect that when the infinite rope winch is in use, when the take-up wheel stops rotating, the dual-axis motor is used to simultaneously drive the two threaded rods, so that the two sleeves rotate on the two threaded rods, thereby driving the two moving frames to move toward the take-up wheel, so that the multiple insertion columns on the two moving frames are respectively inserted into the multiple holes, and then the position of the take-up wheel is locked, which can reduce the working pressure of the take-up wheel on the motor, protect the motor, and thus ensure the operating efficiency of the infinite rope winch.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Example 1: Reference Figure 1-4The endless rope winch comprises a base 1, on which a take-up wheel 2 is rotatably provided, on which a motor 3 and a steel wire rope 4 are fixed, and the motor 3 is fixed on the base 1. A locking mechanism is provided on the take-up wheel 2. When the take-up wheel 2 does not need to rotate, the locking mechanism is used to lock the take-up wheel 2, so that the take-up wheel 2 no longer rotates, and at the same time, the working pressure on the motor 3 is reduced. At the same time, the setting of the locking mechanism will not be affected when the take-up wheel 2 needs to rotate;

[0018] The locking mechanism includes a plurality of holes 5, which are evenly symmetrically and coaxially arranged on the take-up wheel 2. A movable frame 13 is symmetrically arranged on both sides of the take-up wheel 2. A plurality of insertion columns 14 are fixed on the movable frame 13. The plurality of insertion columns 14 are respectively inserted into the plurality of holes 5. An adjustment mechanism is commonly fixed on the two movable frames 13. The adjustment mechanism is fixed on the base 1. The distance between the two movable frames 13 and the take-up wheel 2 can be adjusted by using the adjustment mechanism, so that the plurality of insertion columns 14 can be respectively inserted into the plurality of holes 5, or the plurality of insertion columns 14 can be respectively pulled out from the plurality of holes 5.

[0019] During use, when the take-up wheel 2 stops rotating, the adjustment mechanism is used to adjust the positions of the two mobile frames 13, so that the two mobile frames 13 are close to the take-up wheel 2 until the multiple insertion columns 14 on the two mobile frames 13 are respectively inserted into the multiple holes 5, thereby locking the position of the take-up wheel 2. This can reduce the working pressure of the take-up wheel 2 on the motor 3, protect the motor 3, and ensure the operating efficiency of the endless rope winch.

[0020] Example 2: Based on Example 1, Figure 1-4 As another preferred embodiment of the utility model, the difference from embodiment 1 is that the adjustment mechanism includes a plurality of fixed columns 6, the plurality of fixed columns 6 are fixed on the base 1, a top plate 7 is fixed on the plurality of fixed columns 6, an adjustment component is fixed on the top plate 7, the adjustment component is fixed on the two mobile racks 13, and the adjustment component simultaneously adjusts the positions of the two mobile racks 13 so that the two mobile racks 13 move synchronously.

[0021] The adjusting component includes a double-axis motor 8, which is fixed on the top plate 7. Threaded rods 9 are fixed on the two output shafts of the double-axis motor 8. First fixing plates 12 are rotatably provided on the two threaded rods 9. The two first fixing plates 12 are fixed on the top plate 7. The two threaded rods 9 are limited by the two first fixing plates 12 without affecting the rotation of the two threaded rods 9. Sleeves 10 are threadedly sleeved on the two threaded rods 9. Fixed rods 11 are fixed on the two sleeves 10. The two fixed rods 11 are respectively fixed on two moving frames 13. Limiting components are provided on the two moving frames 13. Each limiting component is fixed on two fixed columns 6. With the assistance of the two limiting components, the two sleeves 10 will not rotate when moving on the two threaded rods 9, thereby ensuring that the two moving frames 13 can only move in a straight line when the position is adjusted.

[0022] The limiting assembly includes a second fixing plate 16 , which is fixed on two fixing columns 6 , and a limiting rod 15 is slidably penetrated on the second fixing plate 16 , and the limiting rod 15 is fixed on the moving frame 13 , and the limiting rod 15 is made of a self-lubricating rod.

[0023] When in use, start the motor 8, which drives the two threaded rods 9 to rotate at the same time. The two limit rods 15 and the second fixed plate 16 cooperate with each other to limit the moving paths of the two mobile frames 13. When the two threaded rods 9 drive the sleeve 10 to move, the two mobile frames 13 can only move along a straight line toward the take-up wheel 2, so that the multiple insertion columns 14 can be accurately inserted into the multiple holes 5 respectively, thereby achieving the purpose of locking the take-up wheel 2.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
