One-way hook overspeed braking mine car with toothed brake rail

Abstract

The invention discloses a unidirectional coupling overspeed brake-type minecart with a toothed brake rail. A brake anti-run-away component is mounted on a machine frame in the direction of the forward motion of the minecart; the toothed brake rail is arranged parallel to the minecart rail and is fixedly mounted between two minecart rails; uniform tooth structures are arranged in the front-rear direction of the upper plane of the toothed brake rail; the brake anti-run-away component comprises an overspeed run-away information collecting and transmitting device, a brake device and a reset device which are arranged corresponding to the toothed brake rail in position; the overspeed run-away information collecting and transmitting device comprises a gear ring, a transmission gear, a transmission shaft, a transmission sleeve and a transmission sleeve axial moving mechanism; the brake device comprises a brake arm and a brake compression spring mechanism; the brake arm is mounted on the minecart axle in a sleeving manner; a brake shaft is arranged at the end of the brake arm; the brake compression spring is positioned and propped against the brake arm and the machine frame; and the reset device comprises a vertical connecting bar and a reset lever. The unidirectional coupling overspeed brake-type minecart disclosed by the invention is simple in structure, and convenient to mount, disassemble and maintain, and rapid mechanical brake in case of run-away accidents can be performed.

Description

technical field [0001] The invention relates to a mine car with a braking function, in particular to a one-way hook overspeed braking type mine car with toothed brake rails suitable for coal mine inclined shaft transportation, and belongs to the technical field of coal mine machinery equipment. Background technique [0002] Inclined mine car brake rail transportation is a transportation method widely used in coal mines and other mines. Phenomena such as broken or out of stock will cause the problem of mine car or mine car train train, cause safe production casualty accident to take place. [0003] At present, the commonly used anti-sports car devices have the following two forms. One is to detect the running speed of the mine car through sensors in the mine. The weight of the device is heavy, and it is inconvenient to install, carry and maintain on site, and it is difficult to popularize it. The interception device can only be used once, which not only wastes materials, but...

Problems solved by technology

[0003] At present, the commonly used anti-sports car devices have the following two forms. One is to detect the running speed of the mine car through sensors in the mine. The weight of the device is heavy, and it is inconvenient to install, transport and maintain on site, and it is difficult to popularize it; the interception device 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

[0004] The other is to install electronic detection equipment on the mine car, and use brake claws to brake the mine car. The disadvantage of this method is that the equipment debugging and maintenance procedures are complicated and complicated, and the electronic products used in the equipment are dust-proof, anti-corrosion, etc. The corrosion performance is poor, and the performance of electronic products is unstable after long-term use, and sometimes it will fail, fail or malfunction at critical moments; cost, and still less than 100% interception effect
