Description

Technical Field

[0001] The utility model relates to the technical field of car arresters, in particular to a car arrester for an inclined tunnel in a mine. Background Art

[0002] Mine ramp car blockers are very important for the safety of mine ramps. They can effectively limit the sliding speed of vehicles, ensure the safety and stability of coal mine production operations, and reduce the risk of accidents. At the same time, regular inspections and maintenance are also required to ensure the stability and safety of the ramp car blockers and reduce the incidence of safety accidents. Mine ramp car blockers are mainly installed under the mine car track, and the base of the mine ramp car blocker and the mine car track are fixed by fixings to complete the installation of the mine ramp car blocker. The fixings in the prior art are mainly as follows: Figure 7 As shown, the base of the mine inclined tunnel car stopper and the track are fixed by using a pressure plate 200, and the fasteners usually use bolts 100. When the mine car is running, the track is always in a vibrating state, and when the mine car touches the mine inclined tunnel car stopper, it will cause greater vibration. Although there is a shock absorbing mechanism, there will still be vibration, which makes the bolts easy to loosen. Therefore, each subsequent maintenance requires a lot of time and effort to check the tightness of the bolts, and the tightening effect of the pressure plate 200 is poor when the bolts 100 are used to tighten the pressure plate.

[0034] Example 2: Please refer to Figure 1 , 2 5. On the basis of Example 1, the following structure is also provided: a first baffle 14 is fixed to the end of one rectangular plate 10 extending outside the base 1, and the first baffle 14 is used to slide and limit the rectangular plate 10 at one end, and the other rectangular plate 10 is arranged in an L shape, and a positioning groove 15 and a slide groove 17 are provided on the lateral end of the L-shaped rectangular plate 10. The L-shaped rectangular plate 10 has a positioning groove 15 and a slide groove 17 on its lateral end, and the L-shaped design provides additional structural stability and connectivity. A second baffle 16 is embedded in the positioning groove 15, and the second baffle 16 is located in the positioning groove 15, and is used to prevent or limit the movement range of the positioning rod 18 to ensure the stability and safety of the system.

[0035] A positioning hole 19 is provided on the second baffle 16, and a positioning rod 18 is inserted into the positioning hole 19, and the positioning rod 18 is slidably matched with the slide groove 17. The slide groove 17 accommodates the sliding of the positioning rod 18 and the pull rod 20, so that these components can move within a certain range while maintaining the stability of their relative positions. A pull rod 20 is fixed to the other end of the positioning rod 18, and the pull rod 20 passes through the rectangular plate 10 and slides with the slide groove 17 to transmit force or movement to control the movement of the positioning rod 18, and the pull rod 20 passes through the rectangular plate 10 and slides with the slide groove 17. An elastic member 21 is sleeved on the pull rod 20, and one end of the elastic member 21 is fixedly connected to the positioning rod 18, and the other end of the elastic member 21 is in conflict with the top of the slide groove 17. When in use, when the positioning groove 15 on the other rectangular plate 10 is moved out of the base 1, the pull rod 20 is first pulled to move the positioning rod 18 into the slide groove 17, and then the second baffle 16 is inserted into the positioning groove 15. When the middle part of the second baffle 16 moves to the pull rod 20, the pull rod 20 is released, and the positioning rod 18 is driven to move under the rebound force of the elastic member 21, so that the positioning rod 18 is inserted into the positioning hole 19, that is, the second baffle 16 is fixed. At this time, the first baffle 14 and the second baffle 16 are respectively fixed on both sides of the base 1, and the wedge-shaped extrusion plate 13 will not move. The movable plate 8 does not move, that is, the fixing member 5 is firmly fixed. The elastic member 21 can use a spring or other device. Under normal conditions, the elastic member 21 enables the positioning rod 18 to be inserted into the positioning hole 19, thereby fixing the second baffle 16. Since the first baffle 14 and the second baffle 16 are respectively located on both sides of the base 1, the wedge-shaped extrusion plate 13 does not move. Even if the base 1 vibrates, the positioning rod 18 does not fall out of the positioning hole 19, thereby ensuring that the fixing member 5 can firmly fix the mine car track 2 and the car blocker body 3 together.
