Description

Technical Field

[0001] The utility model relates to the technical field of mine equipment, in particular to an underground anti-collision vehicle stopper. Background Art

[0002] The mining industry refers to the extraction of naturally occurring minerals, whether solid (such as coal and minerals), liquid (such as crude oil), or gas (such as natural gas). This includes underground or above-ground mining, the operation of mines, and all auxiliary work typically performed at or near the mine site to process raw materials. Mine tunnels and working faces have numerous transport tracks, and vehicles traveling on these tracks need to be controlled. A vehicle stopper is a device that blocks vehicles from rolling, limits their travel, and stops them within a limited distance to prevent them from moving out of service.

[0003] However, the existing car blockers are usually detachable connection structures, and the block column is installed on the base for use, but needs to be disassembled and stored separately when not in use. In this case, the method is relatively complicated and the storage purpose cannot be achieved quickly. Utility Model Content

[0006] Preferably, an internal thread groove is provided inside the positioning sleeve, and the lower end of the blocking column has a threaded end, and the threaded end is threadedly inserted into the internal thread groove.

[0007] Preferably, a rubber sleeve is fixedly connected to the circumferential surface of the blocking column, and the length of the rubber sleeve is smaller than the length of the blocking column.

[0008] Preferably, both ends of the bottom plate have a vertical bending portion, and two screw holes are provided on the bending portion, and second bolts are threadedly inserted into the inner parts of the screw holes.

[0009] Preferably, a strip-shaped opening is provided on the bent portion of the bottom plate, and the strip-shaped opening is located between the two screw holes.

[0010] Preferably, the positioning ring is located above the baffle, and the first bolt is vertically arranged in the positioning ring.

[0011] The utility model provides an underground anti-collision vehicle stopper, which has the following beneficial effects:

[0012] 1. In the utility model, when the blocking column needs to be used, the blocking column is rotated to a vertical direction, and then the first bolt is screwed into the socket through the positioning ring to lock the position of the blocking plate and the blocking column, thereby achieving the purpose of limiting and blocking the mine car; when not in use, the blocking column can be rotated to a horizontal direction, which will not restrict the movement of the mine car and can achieve faster and more convenient storage.

[0013] 2. In the present invention, the retaining column is connected to the internal thread groove of the positioning sleeve through the threaded end, which ensures that the retaining column can be disassembled and can be replaced in time when damaged, thereby improving the use efficiency. The rubber sleeve on the retaining column achieves the purpose of buffering, which helps to reduce the impact force and noise generated when the vehicle collides. BRIEF DESCRIPTION OF THE DRAWINGS
