Anti-off structure of subway vehicle obstacle detection device

Abstract

The invention relates to an anti-off structure of a subway vehicle obstacle detection device. An obstacle detection device comprises a connecting box and two spring plates arranged in the connecting box; a through hole is formed in the back of the connecting box; a thread sleeve is arranged in the through hole; a bolt fixes the obstacle detection device to a framework connecting piece after penetrating through the two spring plates and the thread sleeve in sequence; a rubber pad is arranged in a gap between the back of the connecting box and the framework connecting piece; a connecting cross rod penetrating through the interiors of the spring plates is also fixed in the connecting box; and the two ends of the connecting cross rod are fixed on the framework connecting piece through anti-offropes. According to the anti-off structure of the subway vehicle obstacle detection device, a stress effect is not generated during the normal mounting of equipment; and after a detection device mounting point is invalid, the anti-off structure generates an effect to prevent safety accidents. The anti-off structure of the subway vehicle obstacle detection device has the advantages of high reliability, simple operation, convenient mounting and low cost. Moreover, the hanging distance is short, the swinging amplitude is small when the anti-off structure is valid, the operation limitation is met, and no secondary damage can be caused.

Description

technical field [0001] The invention relates to the technical field of detachment prevention of subway vehicle underframe equipment, in particular to a detachment prevention structure of a subway vehicle obstacle detection device. Background technique [0002] At present, domestic subway trains all use manned operation mode. The driver operates the train and is responsible for observing the direction of the train to ensure that no obstacles fall off the track. However, with the development of subway vehicle technology, some cities in China gradually use unmanned driving. To improve operating efficiency, obstacle detection devices are gradually and widely used in vehicles to eliminate obstacles that appear on the track during normal driving of the vehicle, and perform emergency braking through sensors; at present, the more reliable way is to steer the vehicle at the front of the vehicle An obstacle detection system based on the principle of mechanical trigger is installed at ...

AI Technical Summary

Problems solved by technology

[0004] This structure is a cantilever structure, which is only fixed on the bogie frame by bolts. The equipment is heavy and bulky. After long-term vibration or obstacle removal and impact, the bolts may become loose and the installation structure may become fatigued, resulting in The entire obstacle detection device falls off, and the device is installed at the front end of the wheel set of the bogie. Once it falls off, it will fall on the front end of the wheel set in the running direction, which may cause damage to the underframe equipment, or cause major safety accidents such as vehicle derailment.
