Description

Technical Field

[0001] This utility model relates to the field of coal mine rail transport equipment, and in particular to a mine car rope locking device. Background Technology

[0002] During mine car transportation, safety ropes need to be securely fastened to the mine car to prevent accidental slippage. The existing method of securing mine car safety ropes is the primitive method of wrapping wire around the rope. One end of the wire is wrapped around the mine car, and the other end is wrapped around the safety rope to achieve the purpose of securing the rope. This primitive method of securing the rope lacks elasticity and cannot generate a sustained locking force, making it extremely easy to loosen and slip during transportation. Furthermore, the wire rope can become stuck on other devices, leading to a derailment accident. Moreover, this primitive method cannot be standardized and poses a safety hazard. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1 and Figure 2 The diagram shows a mine car rope locking device, comprising: a front sealing plate 1, a rear sealing plate 2, a locking hook 3, a cam handle 4, a sliding block 5, and a locking spring 6. The front sealing plate 1 and the rear sealing plate 2 are symmetrically arranged, fixed together, and have a cavity in between. The front sealing plate 1 is provided with a limiting groove 11. Two sliding blocks 5 are fixed to the rear sealing plate 2 inside the cavity to form a vertical sliding groove. The locking hook 3 is limited within the sliding groove. The cam handle 4 is fixed to the rear sealing plate inside the cavity and located below the locking hook. The locking hook 3 is configured with an I-shaped structure. The vertical rod of the locking hook is limited within the sliding groove. Rope grooves 31 are provided on both sides of the bottom end of the top rod adjacent to the vertical rod. The locking hook 3 is fixed to a movable bolt 7. The movable bolt 7 is locked within the limiting groove 11 and fixed to a movable nut 8. The locking spring 6 is fixed at the fixed points of the movable bolt and the cam handle. The cam handle lifts the locking hook, and the locking hook moves upward along the sliding groove, with the rope groove extending out of the cavity.

[0022] The locking hook can be equipped with one or two rope grooves, which can be changed according to actual needs. Two rope grooves can fix two ropes at the same time, making it convenient and quick to use when fixing multiple ropes. The symmetrical design of the front and rear end plates enhances the aesthetics.

[0023] Two movable nuts are installed on the movable bolt. One movable nut is fixed to one side of the locking hook, and the other movable nut is fixed to the outside of the front sealing plate, increasing the stability of the locking hook. The sliding groove limits the left and right movement of the vertical rod of the locking hook, and limits the up and down movement of the top and bottom rods of the locking hook, increasing the stability of the locking hook's movement.

[0024] The cam handle 4 is fixed to the rear end plate by a stationary bolt and passes through the front end plate to the outside. A stationary nut is provided on the stationary bolt, and one end of the locking spring 6 is fixed to the stationary bolt outside the front end plate. The cam handle 4 includes a handle part and an arc-shaped part. The horizontal end of the arc-shaped part is connected to the handle part, and the arc-shaped part abuts against the bottom rod of the locking hook.

[0025] Under normal conditions, the arc-shaped part of the cam handle contacts the bottom rod of the locking hook, the locking spring is in its normal state, and the rope groove is located in the cavity of the front and rear sealing plates. When force is applied to the cam handle, the cam handle lifts the locking hook, and the rope groove extends out of the front and rear sealing plates. The rope that needs to be fixed passes through the rope groove. When the cam handle is released, the cam handle is pulled down under the action of the locking spring, resetting the locking hook. The locking action causes the rope to be locked in the cavity between the front and rear sealing plates. This locking method makes the rope stuck in the rope groove and pressed against the inner sides of the front and rear sealing plates on both sides of the locking hook, thus enhancing the locking performance.

[0026] Two clamping plates 9 are fixed on the rear sealing plate inside the cavity. The outer sides of the two clamping plates 9 are flush with the outer side of the rear sealing plate, and the inner sides are aligned with the outer side of the locking hook. The thickness of the two clamping plates 9 is greater than the thickness of the locking hook 3. The clamping plates can directly adjust the thickness of the cavity between the front sealing plate and the rear sealing plate, and increase the strength and stability of the connection between the front sealing plate and the rear sealing plate.

[0027] In use, the mine car rope locking device of this utility model is fixed on the mine car, so that the cam handle pushes up the locking hook, the rope passes through the rope groove, the cam handle is released, and the locking hook locks the rope between the front sealing plate and the rear sealing plate under the action of the locking spring.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
