Abstract

The invention relates to a mis-rotation prevention device for a rail wagon braking system. The mis-rotation prevention device comprises a horse-shoe collar, two seat plates and a spring and is characterized in that the horse-shoe collar is a closed elliptical ring body, an upper mounting hole and a lower mounting hole are respectively formed in the symmetrical centers of the upper part and the lower part of the horse-shoe collar, the spring is connected into the upper mounting hole, a connecting hole is formed in one end of each seat plate, and the connecting holes in the two seat plates are respectively connected to two sides of the lower mounting hole through hinges. The mis-rotation prevention device has the advantages of simple structure, convenience for installation and high structure reliability; and due to utilization of a mechanical motion principle, the self-rotating phenomenon of a switch shaft in the travelling process of a vehicle is prevented, the switch shaft cannot rotate until working personnel rotate the switch shaft, and therefore the reliability of the braking system is improved.

Description

technical field [0001] The invention relates to an anti-mis-rotation device for a railway freight car braking system, which belongs to the field of safety devices for the railway freight car braking system. Background technique [0002] The transportation tasks undertaken by railway wagons are very heavy. With the continuous improvement of train traction weight and running speed, the requirements for braking technology are getting higher and higher. The role of the distribution valve in the braking system is the same as the human heart. Once it breaks down, the function of the air brake of the entire vehicle will completely fail, and there is no guarantee for driving safety. A switch handle is installed on the dispensing valve, a rotatable switch shaft is installed under the undercarriage of the vehicle, and a connecting rod is installed between the shaft and the switch handle of the distributing valve. The staff standing on both sides of the vehicle can control the switch ...
