Problems solved by technology

[0003] In the prior art, the overturning protection devices for rail vehicles are mostly limited to the improvement and optimization of the rail infrastructure, and the cost is high and it is not easy to popularize
What is still available in the prior art is to limit the lateral displacement of the bogie by using a fixed stop device. This device has a high probability of causing the problem of overrunning the lower limit of various trains, resulting in friction between the device and the track infrastructure.
[0004] The patent "Rail Vehicle Anti-Tipping Device and Rail Vehicle Bogie (Patent No.: 201721732500.X)" uses a guide plate and a stop groove to guide the direction of movement of the electromagnet. Small and provides no lateral restraint

Abstract

The invention discloses a magnetic attraction type railway vehicle anti-overturning device. The device comprises a device mounting base, an electromagnet mounting base, an air cylinder and an electromagnet, the device mounting base is arranged in the middle of a railway vehicle bogie frame, one end of the air cylinder is connected with the device mounting base, and the other end of the air cylinder is connected with the electromagnet mounting base; one end of the electromagnet installation base is connected with the air cylinder and connected with the device installation base through a positioning sleeve, and the other end of the electromagnet installation base is connected with the electromagnet; and the air cylinder extends or contracts along with normal operation or overturning accidents of the railway vehicle, so the electromagnet installation base and the electromagnet are driven to move in the direction of the positioning sleeve. The device is small in size, low in cost, high in reliability, easy to maintain and capable of well improving the safety performance of the rail vehicle under the overturning accident.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a mechanical device for preventing rail vehicle overturning accidents. Background technique [0002] The speed of rail vehicles continues to break through, and the requirements for operational safety are also getting higher and higher. It is of great significance to protect rail vehicles from overturning accidents. [0003] In the prior art, most of the overturning protection devices for rail vehicles are limited to the improvement and optimization of the rail infrastructure, the cost is high and it is not easy to popularize. What is still available in the prior art is to limit the lateral displacement of the bogie by using a fixed stop device. This device has a high probability of causing the problem of overrunning the lower limit of various trains, resulting in friction between the device and the track infrastructure. . [0004] The patent "rail vehicle anti-ov...
