Problems solved by technology

[0002] Under the current environment of rapid development of domestic railway transportation, railway transportation safety is an important factor that must be considered by the railway management department. When the locomotive is running, various factors cause locomotive derailment accidents to occur from time to time. During the derailment process, there are wheels crawling The movement of the rail, that is, the wheel rim climbs up the top surface of the track, causing the locomotive to laterally deviate too much and roll over, causing heavy loss of life and property

Embodiment Construction

[0015] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0016] refer to figure 1 As shown, a railway locomotive anti-derailment equipment, said anti-derailment equipment includes a group of mutually symmetrical I-shaped support seats 11 arranged under the track bolster 8, and a bottom connected to the wheel axle box 4 by bolts. Two groups of symmetrical L-shaped brackets 6, and the roller bearings 9 fixed on the tail end of the L-shaped brackets by bolts and the rubber rollers 10 wrapping the roller bearings. The tail end of the L-shaped bracket stretches into the space in the middle of the support seat, and the distance 13 between the top of the roller and the top of the support seat is less than the height of the locomotive wheel rim 12 protrusions.

[0017] There is a certain distance between the roller 10 and the top of the support seat 11, which will not be triggered when the locomotive is running...

Abstract

Provided is a derailment prevention apparatus for a locomotive. The derailment prevention apparatus comprises: a supporting base (11) disposed under a railway bolster (8); a mounting support (6) disposed on a wheel shaft box (4); and a derailment prevention device disposed at a distal end of the mounting support (6). The derailment prevention apparatus for a locomotive realizes a position-limiting effect on relative movements of a wheel (7) and a locomotive track (7) in a vertical direction, thereby preventing derailment effectively.

Description

technical field [0001] The invention relates to a vehicle protection device, in particular to an anti-derailing device for locomotives and vehicles applied to new high-priced railway lines. Background technique [0002] Under the current environment of rapid development of domestic railway transportation, railway transportation safety is an important factor that must be considered by the railway management department. When the locomotive is running, various factors cause locomotive derailment accidents to occur from time to time. During the derailment process, there are wheels crawling The movement of the rail, that is, the wheel rim climbs up the top surface of the track, resulting in excessive lateral deviation of the locomotive and rollover, resulting in heavy loss of life and property. Contents of the invention [0003] The object of the present invention is to: provide a kind of anti-derailment equipment of railway rolling stock, realize by following technical scheme:...
