Problems solved by technology

[0002] At present, the light vehicles used on railways are generally engaged in special work such as maintenance and cleaning. When a large lateral force is encountered, one side of the steel wheel may break away from the rail, and the vehicle rolls over. The existing vehicles of this type have no effective protection measures.

Embodiment Construction

[0011] Such as figure 1 As shown, the present invention includes a hook body 1, a plane sliding bearing 2, a movable pin 3, a fixed pin 4 and a base 5. The base 5 is fixed on the vehicle body or the steel wheel connection bracket, one end of the hook body 1 is connected to the base 5 through the fixed pin 4, the middle part of the hook body 1 is connected to one end of the base 5 through the movable pin 3, and the movable pin 3 is connected to the base 5. When the connecting hole is clearance fit, and when the present invention is in working condition, the free end of the hook body is positioned at the lower side of the lower side of the rail track. The hook body 1 can rotate around the fixed pin shaft 4 . The hook groove of the hook body is equipped with a plane sliding bearing 2. When the vehicle rolls over, the plane sliding bearing 2 is in contact with the side of the rail. The plane sliding bearing 2 prevents the rail and the hook body from being damaged due to friction ...

Abstract

The invention relates to a rollover preventing device for railway vehicles. Derailment of steel wheels of the railway vehicles is prevented. The rollover preventing device comprises a hook (1), a plane slide bearing (2), a movable pin (3), a fixed pin (4) and a base (5). The base (5) is fixed on a vehicle body or a connecting support of steel wheels. One end of the hook (1) is movably connected with the base (5) through the fixed pin (4). The middle of the hook (1) is connected with one end of the base (5) through the movable pin (3). The movable pin (3) is in clearance fit with a connecting hole of the base (5). A free end of the hook (1) is located on the lower side of the lower side of a rail. The plane slide bearing (2) is mounted in a hook groove of the hook. When rollover occurs, the plane slide bearing (2) is contacted with the side of the rail.

Description

technical field [0001] The invention belongs to a device used on a railway vehicle, in particular to an anti-rollover device for a railway vehicle. Background technique [0002] At present, light vehicles used in railways are generally engaged in special work such as maintenance and cleaning. When a large lateral force is encountered, one side of the steel wheel may break away from the rail, and the vehicle rolls over. The existing vehicles of this type have no effective protection measures. . Contents of the invention [0003] The invention provides an anti-rollover device for a railway vehicle, which prevents the steel wheel from detaching from the rail when the vehicle is subjected to a large lateral force, ensures that the vehicle does not rollover, and ensures the normal use of the vehicle. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is that an anti-rollover device for railway vehicles includes a ...
