[0017] In the following, in order to facilitate the person skilled in the art to understand the technical scheme of the utility model, the further description is made with reference to the drawings. It should be understood that these descriptions are only exemplary, and are not intended to limit the scope of the utility model.

[0018] In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the embodiments of the utility model. However, it is apparent that one or more embodiments can be implemented without these specific details. In addition, in the following description, the description of the known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] Please refer to Figs. 1-3This utility model relates to a magnetic wheel stopper for track mining cars, comprising a triangular base 1, with magnets 2 installed at the bottom of both sides of the triangular base 1 for adsorption onto the track surface. Baffles 3 are laid on both sides of the inclined surface of the triangular base 1, and wheel grooves 4 are carved opposite each other in the middle of the baffles 3. A wheel stop bar 5 is installed on the surface of the baffle 3 near the edge of the wheel groove 4. In practice, a buffer elastic element 12 is installed between the wheel stop bar 5 and the baffle 3 to buffer the impact of the mining car wheel with the wheel stop bar. The surface of the wheel stop bar 5 is stepped. Fan-shaped baffles 6 are installed on both sides of the triangular base 1, with the center point of the fan-shaped baffles 6 rotatably connected to the side of the triangular base 1 by bolts 7. When the arc end of the fan-shaped baffle 6 reaches its lowest point, it is lower than the bottom edge of the triangular base 1. In practice, a lever 11 for rotating the fan-shaped baffle 6 is vertically installed on its surface. A handle groove 8 is provided at the center of the top of the triangular base 1. A handle 9 is installed in the handle groove 8 with a self-tapping screw for easy movement.

[0020] In some embodiments, a cover plate 10 is provided below the magnet 2, and one side of the cover plate 10 is hinged to the bottom surface of the triangular base 1. The cover plate 10 can cover the magnet when the vehicle stopper is not in use.

[0021] In addition, to further buffer the vehicle's sliding allowance, a buffer arc surface 13 is provided on the bottom surface of the wheel stop bar 5, and the end of the buffer arc surface 13 is flush with the bottom surface of the triangular base 1.

[0022] In summary, the magnetic wheel stopper for mine cars designed in this utility model can simultaneously stop both wheels of the vehicle, avoiding the technical problems of difficulty in stopping vehicles on the inner side of the track and difficulty in operation. The triangular base has a magnet at its bottom for stable vehicle stopping, preventing the stopper from being pushed off the track when the vehicle moves. The wheel groove is slotted according to the wheel spacing of the mine car; when stopping the vehicle, the wheel engages in the groove, allowing the wheel cross-section to contact the stop bar more quickly, achieving rapid braking. The stop bar has a stepped surface, effectively buffering the vehicle's sliding allowance. The fan-shaped baffles on both sides effectively prevent the stopper from wobbling to the sides of the track due to accidental vehicle movement or external contact, thus preventing it from slipping off the track.
