Description

Technical Field

[0001] This utility model relates to the field of mineral construction technology, specifically a safety well cage protection door. Background Technology

[0002] A mine cage safety door is a specialized safety device designed for use in underground mines such as coal mines and shafts to prevent miners from accidentally entering dangerous areas. This device is usually installed at the mine entrance or a specific work location underground. Its main function is to prevent miners from entering dangerous areas, thereby ensuring their safety. Using mine cage safety doors can greatly reduce the risk of injury to miners during the mining process, improve the level of mine safety management, and effectively prevent mass casualty accidents caused by miners accidentally entering dangerous areas.

[0003] In use, existing mine cage safety doors typically employ a roller shutter design with steel bars and chains. The steel bars have rings on both sides that fit onto the vertical steel bars on either side of the cage door for fixation. When personnel enter or exit the cage, they manually lift the roller shutter and hang it on hooks at the top inside the cage. When mine cars or materials are loaded or unloaded from the cage, they frequently collide with or scrape against the vertical steel bars on either side of the cage door, causing the bars to bend or the bottom welds to detach. Lifting the roller shutter is difficult and hinders its normal use. Furthermore, maintenance of the safety door disrupts production.

[0004] Therefore, it is necessary to provide a new type of safety cage protection door to solve the above-mentioned technical problems. Utility Model Content

A pull rope 9 is provided at the top of the fixed plate 8. One end of the pull rope 9 is fixedly connected to a support plate 10. The support plate 10 can be pulled up by the pull rope 9. A box 11 is fixedly connected to the bottom of the support plate 10. A drive mechanism 12 is provided inside the box 11. The drive mechanism 12 is a motor screw structure in the prior art, which will not be described in detail here. A guide wheel 13 is provided on the outside of the box 11. The guide wheel 13 can guide the protective plate 5 to avoid the problem of shaking when the protective plate 5 and the support plate 10 are raised and lowered.

[0024] Multiple sets of hooks 14 are provided on one side of the cage 1. A hanging ring 15 is provided on the outer side of the hook 14.

The wire rope 2 is tough and elastic, preventing damage from collisions and scrapes. One end of the wire rope 2 can be fixed by the U-shaped buckle 7. Rotating the connecting bracket 16 moves the threaded rod 17 upward, causing the pull ring 18 to tighten the lifting ring 6, thus controlling the tension of the wire rope 2. The drive motor 19 and the winding seat 20 then wind up the pull rope 9. As a result, the support plate 10 is moved, and the protective rod 4 can be pulled up by the hook 28. The drive block 21 is moved by the drive mechanism 12, so that the connecting rod 22 pushes the connecting block 23 to slide on the outside of the support rod 24, which drives the fixing block 25 to move, so that the mounting rod 26 pushes the guide wheel 13 to contact the inner wall of the cage 1. The guide wheel 13 can guide the protective plate 5, avoid the problem of shaking when the protective plate 5 and the support plate 10 are raised and lowered, and improve the stability of the protective plate 5 when it is raised and lowered.
