Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a mine dredging and lifting device with a locking function. Background Art

[0002] A chute is a tunnel that uses its own weight to slide ore from top to bottom. As the main transportation channel for mine ore, the chute plays a very important role in the mining process. Once the chute is blocked for some reason, it will seriously affect the normal production of the mine and even cause production to stop. When using explosives to dredge a blocked chute, telescopic parts are generally used to support the explosives (such as the public document of a telescopic support device for dredging a chute with announcement number CN220955707U). However, when the telescopic support device is extended to lift the explosives, the staff needs to pull the pull rope on the outside of the blocked area, and after the telescopic support device pushes the explosives to the predetermined area, the pull rope needs to be actively fixed, which increases the operating steps and is more troublesome. Utility Model Content

[0003] The purpose of the utility model is to provide a mine dredging and lifting device with a locking function to solve the problem that when the telescopic support device proposed in the above-mentioned background technology is extended to lift the explosives, the staff needs to pull the pull rope outside the blocked area, and after the telescopic support device pushes the explosives to the predetermined area, the pull rope needs to be actively fixed, which is quite troublesome.

[0004] To achieve the above object, the utility model provides the following technical solution: a mine dredging and lifting device with a locking function, comprising: a telescopic member, a winding wheel is provided on the fixed end of the telescopic member, and a flexible connecting member is provided between the winding wheel and the lifting end of the telescopic member;

[0005] A driving member for driving the winding wheel to rotate is provided on the fixed end of the telescopic member;

[0006] A locking piece is provided on the fixed end of the telescopic piece;

[0007] The locking member includes a mounting member, a card plate hinged on the mounting member, and an elastic member arranged between the mounting member and the card plate. The mounting member is arranged on the fixed end of the telescopic member, and the elastic member is used to pull the card plate closer to the winding wheel to prevent the winding wheel from rotating in the opposite direction after rotation.

[0008] Preferably, a ratchet is provided on the shaft of the winding wheel, and one end of the clamping plate away from the mounting member is inserted between the teeth of the ratchet.

[0009] Preferably, a socket is provided on the shaft of the winding wheel, the output shaft of the driving member is inserted into the socket, and the cross section of the output shaft of the driving member matches the cross section of the socket.

[0010] Preferably, the cross-section of the socket is non-circular.

[0011] Preferably, the driving member is a driving motor.

[0012] Preferably, the lifting device further comprises a clamping device, and the telescopic member and the driving member are both arranged on the clamping device.

[0013] Preferably, an elastic pad is provided in the contact area between the clamping device and the telescopic member.

[0014] Preferably, the flexible connector is a steel wire rope.

[0015] Preferably, the telescopic member is a two-stage or multi-stage telescopic member.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. Pull the card plate closer to the winding wheel through the elastic member, so that the end of the card plate is inserted between the adjacent teeth of the ratchet wheel, which is used to limit the rotation of the ratchet wheel, so that the winding wheel of the rotating winding flexible connector will not rotate in the opposite direction, so that the flexible connector does not need to be fixed separately after pulling the telescopic member to extend, thereby reducing the operating steps in the process of dredging the mine shaft and improving the dredging efficiency;

[0018] 2. When the clamping device releases the telescopic part, the driving part will be separated from the ratchet, so that the driving part can be recovered and reused, reducing the cost of dredging the mine shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A mine dredging and lifting device with a locking function comprises a telescopic member 1, a bracket is installed on the fixed end of the telescopic member 1, a winding wheel 2 is rotatably installed on the bracket, a flexible connecting member 3 (wire rope) is provided on the winding wheel 2, and one end of the flexible connecting member 3 away from the winding wheel 2 is connected to the lifting end of the telescopic member 1.

[0028] It should be noted that the telescopic member 1 is a telescopic rod, which is a two-stage telescopic rod or a multi-stage telescopic rod. The telescopic rod is made of a PVC tube. The following takes a two-stage telescopic rod as an example (such as Figure 5 As shown in the figure, the upper PVC tube is slidably inserted into the inner cavity of the lower PVC tube, and the end of the flexible connector 3 away from the winding wheel 2 extends into the inner cavity of the lower PVC tube and is connected to the bottom end of the upper PVC tube, so that when the flexible connector 3 is wound by the winding wheel 2, the flexible connector 3 pulls the upper PVC tube to move upward.

[0029] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 A driving member 5 is provided on the fixed end of the telescopic member 1. The driving member 5 refers to a driving motor, which is used to drive the winding wheel 2 to rotate.

[0030] See also Figure 4 , a locking member is provided on the fixed end of the telescopic member 1;

[0031] Among them, the locking member includes a mounting member 7 (such as a plate-shaped member), a card plate 8 hinged on the mounting member 7, and an elastic member 9 (spring) arranged between the mounting member 7 and the card plate 8. The mounting member 7 is installed on the fixed end of the telescopic member 1; a ratchet 6 is fixedly sleeved on the axis of the winding wheel 2, and the end of the card plate 8 away from the mounting member 7 is inserted between the teeth of the ratchet 6. The elastic member 9 is used to pull the card plate 8 closer to the winding wheel 2 so that the end of the card plate 8 is stuck between the adjacent teeth of the ratchet 6 to limit the reverse rotation of the ratchet 6 and the winding wheel 2 (reverse rotation refers to the direction in which the winding wheel 2 rotates in the opposite direction of the winding flexible connecting member 3).

[0032] It should be noted that, in the process of clearing the ore chute, the explosive is fixedly installed on the jacking end of the telescopic member 1, and then the telescopic member 1 is moved to the ore chute that needs to be cleared, and then the driving member 5 works to rotate the winding wheel 2, and the flexible connecting member 3 is wound around the outer wall of the winding wheel 2, so as to pull the jacking end of the telescopic member 1 upward and push the explosive to the bottom of the ore blocking the ore chute; when the winding wheel 2 rotates, the ratchet 6 will also rotate synchronously. In this process, the elastic member 9 pulls the clamping plate 8 to move, so that one end of it is inserted between the teeth of the ratchet 6, which is used to limit the reverse rotation of the ratchet 6, so that the winding wheel 2 will not release the wound flexible connecting member 3; and in the process of the driving member 5 driving the ratchet 6 and the winding wheel 2 to rotate, the teeth of the ratchet 6 will push the clamping plate 8 to move it away from between the teeth of the ratchet 6, so that the ratchet 6 can rotate normally and will not affect the normal winding of the flexible connecting member 3 by the winding wheel 2.

[0033] Example 2

[0034] As a further optimized solution of Example 1, please refer to Figure 1 , Figure 2 and Figure 3 The lifting device also includes a clamping device 4, which refers to an electric clamp, which is clamped on the fixed end of the telescopic member 1; the telescopic member 1 is clamped by the electric clamp and moved with it.

[0035] In this embodiment, as a further optimized solution, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the driving motor is arranged on the clamping device 4; a socket 10 is opened on the shaft of the winding wheel 2, the socket 10 is located on the axis of the winding wheel 2, the output shaft of the driving motor is inserted into the inner cavity of the socket 10, and the cross section of the output shaft of the driving motor matches the cross section of the socket 10; after the clamping device 4 moves the telescopic member 1 to the predetermined area for placement, the clamping device 4 releases the telescopic member 1 and moves with the driving member 5, so that the output shaft of the driving member 5 is moved out of the socket 10, and the driving member 5 is separated from the winding wheel 2, so that the driving member 5 is removed from the jacking device, and the driving member 5 can be recycled before blasting and dredging, saving costs.

[0036] In this embodiment, as a further optimized solution, please refer to Figure 4 The cross section of the socket 10 is non-circular; the output shaft of the driving member 5 will not idle in the socket 10, ensuring that the driving member 5 can rotate with the winding wheel 2 when working.

[0037] In this embodiment, as a further optimized solution, please refer to Figure 1 An elastic pad (made of rubber) is provided in the contact area between the clamping device 4 and the telescopic member 1, so that the clamping device 4 and the telescopic member 1 are in closer contact, ensuring that the clamping device 4 clamps the telescopic member 1 stably.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
