Description

Technical Field

[0001] The utility model belongs to the technical field of mining hoisting equipment, in particular to a limiting device for a hook plate wheel of a ore loading bucket. Background Art

[0002] As the scale of mines and the depth of mining continue to increase, most of the main shaft hoists in underground mines have adopted the bucket hoisting method. There is a self-protection device on the bucket, that is, the hooks on both sides of the bucket. When the bucket enters the unloading curved track, the hook plate wheel is pushed to disengage the bucket hook plate from the lug, and the bottom of the bucket is opened to complete the unloading of ore; when the bucket leaves the curved track, the bucket hook plate is hooked on the lug again to ensure that the bucket operates normally during acceleration, deceleration and full speed operation.

[0003] Because there is no limiting device on the hook wheel on the bucket hook plate during the swinging process, after the bottom of the bucket is opened, the front end of the hook plate cannot be accurately hung on the frame position, resulting in a malfunction. Utility Model Content

[0004] The utility model aims at the problem that the hook plate wheel on the bucket hook plate in the prior art is not limited and causes malfunction, and proposes the following technical solutions:

[0005] The limiting device of the hook plate wheel of the loading skip comprises: a hook plate and a limiting assembly, a rotating shaft is rotatably inserted in the middle of the hook plate, the rotating shaft is fixedly connected to the loading skip, a hook plate wheel is arranged on the top of the rotating shaft, the limiting assembly comprises a limiting push frame and a driving member, the driving member pushes the limiting push frame to move in direction A, and the limiting push frame is on the surface of the hook plate wheel.

[0006] As a preferred embodiment of the above technical solution, the limit assembly also includes a compensation part, which includes a moving block, one end of the moving block is fixedly connected to the driving part, and the other end of the moving block is movably connected with the compensation block, both ends of the compensation block are fixedly connected to the moving block through a return spring, and one end of the compensation block is fixedly connected to the limit push frame.

[0007] As a preferred embodiment of the above technical solution, the cross-section of the limit push frame is circular, and the inner surface of the limit push frame is in contact with the surface of the hook wheel.

[0008] As a preferred embodiment of the above technical solution, the cross-section of the compensation block is rectangular, and the insertion point of the moving block matches the compensation block.

[0009] The beneficial effects of the utility model are:

[0010] 1. The limit push frame is sleeved on the surface of the hook plate wheel to limit its path. The limit push frame can control the swing of the hook plate wheel to avoid malfunctions, thereby solving the safety hazard of the bottom of the bucket opening when the skip is loaded with ore;

[0011] 2. The compensation component set can meet the displacement of the hook plate wheel when the hook plate rotates, and because the compensation block only moves in the moving block, the A of the hook plate wheel can be limited upward, thereby ensuring the stable state of the hook plate wheel.

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings of the specification.

[0016] Example

[0017] Figure 1-Figure 2 In the figure, the limiting device of the hook plate wheel 30 of the loading bucket comprises: a hook plate 10 and a limiting assembly, a rotating shaft 20 is rotatably inserted in the middle of the hook plate 10, the rotating shaft 20 is fixedly connected to the loading bucket, a hook plate wheel 30 is arranged on the top of the rotating shaft 20, and the limiting assembly comprises a limiting push frame 41 and a driving member 42. In this technical solution, the driving member 42 is a cylinder, the driving member 42 is fixedly connected to the bucket, the driving member 42 pushes the limiting push frame 41 to move in the A direction, and the limiting push frame 41 is on the surface of the hook plate wheel 30.

[0018] The cross section of the position limiting push frame 41 is circular, and the inner surface of the position limiting push frame 41 is in contact with the surface of the hook wheel 30 .

[0019] When the bottom of the bucket is opened, the driving member 42 starts to push the limit push frame 41 to move, and the limit push frame 41 moves the hook plate wheel 30 in direction A, and the hook plate 10 rotates in direction B around the rotating shaft 20, and the hook plate 10 becomes separated from the hook ear position, and the circular limit push frame 41 limits the upward path of the hook plate wheel 30A to prevent the hook plate wheel 30 from swinging.

[0020] The limit push frame 41 is sleeved on the surface of the hook plate wheel 30 to limit its path. The limit push frame 41 can control the swing of the hook plate wheel 30 to avoid malfunction, thereby solving the safety hazard of the bottom of the bucket opening when the bucket is loaded with ore.

[0021] Figure 1-Figure 2In the figure, the limiting assembly also includes a compensation member 43, and the compensation member 43 includes a moving block 431. One end of the moving block 431 is fixedly connected to the driving member 42, and the other end of the moving block 431 is movably connected with a compensation block 432. The compensation block 432 only reciprocates in the C direction within the moving block 431. Both ends of the compensation block 432 are fixedly connected to the moving block 431 through a return spring 433, and one end of the compensation block 432 is fixedly connected to the limiting push frame 41.

[0022] The cross section of the compensation block 432 is rectangular, and the insertion portion of the moving block 431 matches the compensation block 432 .

[0023] When the limit push rack 41 moves in direction A, the limit push rack 41 will move in direction C along with the rotation of the hook plate 10, and the compensation block 432 will move in the moving block 431 along with the movement of the limit push rack 41, and the return spring 433 at one end will be compressed and deformed, while the return spring 433 at the other end will be stretched and deformed, thereby satisfying the movement of the limit push rack 41.

[0024] The compensation component provided can satisfy the displacement of the hook plate wheel 30 generated when the hook plate 10 rotates by the limit push frame 41, and because the compensation block 432 only moves within the moving block 431, the A of the hook plate wheel 30 can be limited upward, thereby ensuring the stable state of the hook plate wheel 30.

[0025] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
