[0002] Inclined shaft hoisting is a common mining method, typically using a winding hoist to pull mine cars. During the hoisting process, the mine cars are lifted from the inclined shaft to the surface level roadway via an inclined ramp, stopping at a designated stopping point. The stopping time and location are usually determined by the hoist operator through a camera. However, with the continuous development of technology and the popularization of unmanned operation, it is necessary to install detection switches at the stopping points so that the hoist can automatically stop when it reaches the designated stopping point during automatic operation.

[0003] Existing equipment detects positioning status by installing detection switches on both sides of the track or by using pull rope switches. However, sensors installed on both sides of the track are easily damaged or malfunction by falling ore, and using pull rope switches will affect the passage of personnel in the roadway, affecting both personnel and equipment. Furthermore, the replacement and protection of parts are inadequate, and the equipment is inconvenient to use. Therefore, a positioning detection switch device for a mine inclined shaft winding hoist is needed to solve the above problems. Utility Model Content

The feature is that a base plate 1 is fitted to the upper end of the inner wall of the inclined shaft 3, and a fixing bolt 8 is inserted through the inner edge of the base plate 1. The base plate 1 and the extension rod 2 are bolted to the upper end of the inner wall of the inclined shaft 3 by the fixing bolt 8, and the fixing bolt 8 are distributed in a ring on the base plate 1. This facilitates the stable bolt installation of the base plate 1 and the extension rod 2. A rotating seat 10 is vertically fixedly connected to the middle position of the lower end of the base plate 1, and a connecting plate 13 is installed on the inner wall of the rotating seat 10. An induction magnet 16 is fixedly connected to the rear side of the connecting plate 13. A movable rod baffle 11 is vertically fixedly connected to one edge of the lower end of the base plate 1, and both the movable rod baffle 11 and the connecting plate 13 are attached to the base plate 1. The system includes an adhesive block 18, with a splicing magnet 17 fixedly connected to one side of the adhesive block 18. A mounting slot 12 is fixedly connected to the lower end of the connecting plate 13, and positioning slots 23 are provided on the front and rear sides of the inner wall of the mounting slot 12. A positioning plug 22 is inserted into the inner wall of the positioning slot 23. A locking knob 21 is inserted through the sides of the mounting slot 12 and the positioning plug 22. An extension rod 2 is fixedly connected to the lower end of the positioning plug 22. The extension rod 2 and the sensing magnet 16 are connected to the sensor 15 via a rotating base 10 in a reset and flip-up configuration.

[0021] Working principle: When using this type of positioning and detection switch device for a mine inclined shaft winding hoist, the device is first fixed to the upper end of the inner wall of the inclined shaft 3 using fixing bolts 8. The sensor 15 is then electrically connected to the hoist control system via connecting wire 14. When the hoist sends a lifting signal, the hoist begins to lift, and the mine car 5 is lifted from the inclined shaft to the surface level roadway via the inclined ramp. Once on the surface level roadway, the mine car continues forward. When the mine car 5 hits the extension rod 2, the extension rod 2 moves forward along with the mine car via the rotating seat 10. When the induction magnet 16 on the extension rod 2 moves... When the moving rod moves in front of the sensor 15, the sensor 15 activates and transmits a signal to the hoist control system, causing the hoist to stop. When the hoist sends a signal, the mine car leaves the parking point, and the movable rod moves with the mine car. It is magnetically connected and fixed to the movable rod baffle 11 by the splicing magnet 17 to prevent shaking. During operation, the extension rod 2 can be elastically protected against impact by the protective wrapping block 24, while the sensor mounting slot 20 can wrap and protect the sensor 15. It can be quickly screwed on and disassembled for quick replacement. This is the usage process of the positioning detection switch device for a mine inclined shaft winding hoist.
