A disc spring brake mine car

Abstract

The invention discloses a disc spring brake type mine car, wherein the brake anti-running device includes a pull rod connected with the front and rear sections of the mine car, the pull rod passes through the mounting hole on the connecting frame and can slide, and the other end of the pull rod is connected with the pin shaft. The connecting rod is hinged, the other end of the connecting rod is hinged with the rocker through a pin shaft, the rocker is connected with the rocker shaft through a key, and the rocker shaft is installed on the frame through a bearing; the two ends of the rocker shaft are respectively connected with a gear pair, The inner side of the gear at the lower end of the gear pair has multi-line internal threads and cooperates with the external threads of the brake shaft, and the thread pairs on both sides rotate in opposite directions; the brake assembly that is consolidated with the brake shaft and the upper support sleeve of the brake assembly It constitutes a sliding connection; one end of the disc spring set in the brake assembly is in contact with itself, and the other end is in contact with the middle partition in the support sleeve; the two ends of the gear at the middle and lower end of the gear pair are connected with the support sleeve through bearings. The invention has a simple structure, can quickly mechanically brake a sports car in an accident, and is convenient for installation, disassembly and maintenance.

Description

technical field [0001] The invention relates to a mine car, in particular to a disc spring brake type mine car. Background technique [0002] Inclined mine car rail transportation is a mode of transportation widely used in mines such as coal mines. Phenomena such as pinning and causing the problem of mine car or mine car train train, cause safety production casualty accident to often take place. [0003] The commonly used anti-sports car device has following several forms at present, and a kind of is to detect the running speed of mine car by sensor in mine, in case finding stall situation utilizes car net or car bar to block mine car. The disadvantages of this method are: the weight of the intercepting device is heavy, it is inconvenient to install, carry and maintain on site, and it is difficult to popularize and use; the intercepting device can only be used once, which not only wastes materials, but also destroys the continuity of mine production. strenuous.

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: the weight of the intercepting device is heavy, and it is inconvenient to install, carry and maintain on site, and it is difficult to popularize it; the intercepting device can only be used once, which not only wastes materials, but also destroys the continuity of mine production. strenuous

The disadvantages of this method are: equipment debugging and maintenance procedures are complex and complicated, the electronic products used in the equipment have poor dust resistance and corrosion resistance, and the performance of electronic products is unstable after long-term use, and sometimes they will fail at critical moments. Failure or misoperation; What's more, an inclined shaft needs multiple interceptions to achieve a better effect, which not only increases the cost of the mine, but also fails to achieve 100% interception effect
