[0002] In mining excavation projects, rail transportation is a more common mode of transportation, and the cross-section of rail transportation is generally smaller than that of trackless transportation. During underground mining, due to the high noise of underground equipment operation and many bends, the miners working on the vein and segmentation working faces often cannot detect the approaching mine cars in time, which can easily cause safety accidents.

[0003] At present, mine car stoppers are generally set at the starting section of the track, with an electric control cabinet next to it to control the operation of mine cars when loading and unloading materials and ores. When loading and unloading materials in other places, cover wood is used to block the mine cars, and no car stoppers are set up, which can easily cause safety hazards. Utility Model Content

DETAILED DESCRIPTION

[0015] The utility model is described in detail below with reference to the accompanying drawings:

[0016] like Figure 1 and 2 As shown, a rail car stopper includes a block 2 arranged on the upper surface of a track 1, the track 1 is an existing conventional I-beam, the block 2 is a stainless steel structure, the block 2 is arranged along the length direction of the track 1, the front part of the block 2 forms a buffer surface 3, the buffer surface 3 and the upper surface of the track 1 form an angle, in this embodiment, the buffer surface 3 and the upper surface of the track 1 form an angle of 10-30 degrees, when the mine car is moved onto the buffer surface 3, one end of the mine car moves upward, and the kinetic energy is converted into gravitational potential energy to play a role in deceleration, and buffering and deceleration can be performed under the action of the buffer surface 3, and a buffer baffle 4 with an arc structure is provided in the block 2, and the buffer baffle 4 is an arc structure, which can increase the contact area with the mine car wheel and reduce the impact on the buffer baffle 4 The pressure on the wheels of the mine car stops the movement of the mine car through the buffer baffle 4, which plays a role in blocking the car. The buffer baffle 4 can move along the length direction of the block 2 under the action of external force. Specifically, a slide groove 5 is provided in the middle part of the block 2 along the length direction of the block 2, and a slider 6 is provided at the bottom end of the buffer baffle 2. The slider 6 is located in the slide groove and can move in the slide groove 5 along the length direction of the slide groove 5. A fixed plate 7 is provided on the block 2, and the fixed plate 7 is located at the rear end of the slide groove 5. A spring 8 is connected to the fixed plate 7, and the end of the spring 8 away from the fixed plate 7 is connected to the buffer baffle 4. The spring 8 can further buffer the mine car, slow down the mine car, and stop the mine car, thereby preventing the mine car from being damaged by the impact or the car blocker.

[0017] A clamping piece 9 for mounting the block 2 on the track 1 is provided at the bottom of the block 2. Specifically, the clamping piece 9 includes a first connecting plate 901 and a second connecting plate 902 respectively arranged on both sides of the length direction of the block 2. A plurality of first screw holes 903 are provided on the first connecting plate 901 along the length direction of the first connecting plate 901, and a plurality of second screw holes 904 are provided on the second connecting plate 902 along the length direction of the second connecting plate 902. A first fixing bolt 905 is provided in the first screw hole 903, and a second fixing bolt 906 is provided in the second screw hole 904.
