Problems solved by technology
[0004] The interception device in the above scheme (1) can only be used once, which not only wastes materials, but also destroys the continuity of mine production, and it takes time and effort to deal with accidents. (2) It needs to use electronic equipment, which is easy to fail in the harsh inclined shaft environment, and the equipment cost is relatively high, so it is not suitable for the modification and installation of all mine cars

Embodiment Construction
[0022] see figure 1 , figure 2 , the present invention has a car body 2, a slide rail 3 is installed on the wheel 1, and a spring 5 and a slider 6 are installed inside the slide rail 3. When the mine car is in normal operation, the slider 6 slides along the The rail direction slides back and forth, when the speed of the mine car reaches a certain value, the slider 6 is thrown out under the action of centrifugal force, inserted into the hole at the front end of the sliding shaft 7, and the sliding shaft 7 is pulled to move forward, driving the steel wire rope 12 to make the claw hold tightly track to prevent the minecart from continuing to slide. In order to prevent the sliding shaft 7 from moving backward after the mine car decelerates, there is a raised small triangular block on the sliding shaft 7, and there is a concave small triangular groove on the inner side of the hole matched with the sliding shaft 7, so that the sliding shaft 7 can only move along the axis directio...

The present invention relates to an automatic anti-running-away tramcar with clamping rails comprising a tramcar body, an overspeed sensing mechanism arranged on a wheel and a rail-clamping device arranged in the middle of two pairs of wheels, and characterized in that: a. the overspeed sensing mechanism comprises slide rails arranged on the wheels of the tramcar, springs and slide blocks arranged in the slide rails; b. the rail-clamping device comprises a support base arranged in the middle of two pairs of wheels, a pair of clamping claws hinged on the support base by a bolt assembly and a torsion spring arranged between the clamping claws, a wire rope fixed on the right clamping claw (11) passes through the left clamping claw (10) and then is connected with a slide shaft, and the slide shaft cooperates with the support base and can slide forward along the axial direction. The automatic anti-running-away tramcar overcomes problems of complex structure, large arrangement space, unreliable operation and the like in existing tramcar anti-running-away devices and is especially suitable for mine transportation.
Description
technical field [0001] The invention relates to mine safety equipment, which is a rail-holding type automatic anti-running mine car used for carrying people and ore. Background technique [0002] Inclined shaft rail-carried / mine-carrying mine car is usually a main car tow three (or four) ore barrels, and the mine car is lifted to the ground by a winch and a wire rope hanging on the coupler of the main mine car; In the process, if the rope is broken or unhooked, the control will be lost immediately, causing a major sports car accident. The problem of anti-car running in inclined shafts has always been a thorny problem that needs to be solved urgently in mine production. [0003] At present, the solutions to this problem include: (1) in the mine, the running speed of the mine car is detected by a sensor, and the car is blocked by a car barrier or a car net; (2) electronic detection equipment is installed on the mine car, and brake pawls or The rail holding mechanism brakes ...
