Embodiment Construction

[0017] figure 1 , figure 2 As shown in , the hook plate 1 can be integrated with the axle bearing housing 2 through bolting, welding, riveting, casting, etc. to play a role. There is a connecting seat on the upper part of the hook plate 1, and there are screw holes corresponding to the assembly holes at the bottom of the axle bearing box 2 on the connecting seat. When bolted connection is used, the hook plate 1 is installed on each Bottom of axle bearing housing 2. In order to ensure that the hook plate 1 is well bolted to the axle bearing box 2 and that the bolt 3 is not subject to a large shear force after installation, the contact parts of the axle bearing box 2 and the hook plate 1 are processed to ensure that the two installation planes The parallelism between them makes the contact surfaces fit closer together. Bolt 3 adopts GB / T32.1-1988M16X55 bolt with holes in the head. After bolt 3 is tightened, iron wire 7 is used to connect and prevent loosening in an "8" shape...

Abstract

The invention discloses an anti-rollover device of a railway vehicle. The anti-rollover device is a hook plate which is arranged at the bottom of an axle bearing housing of the railway vehicle, wherein a hook is arranged at one end of the hook plate; two hook plates can form a pair and are arranged at the bottoms of the axle bearing housings of a left railway vehicle and a right railway vehicle respectively; openings of the hooks on the hook plates face inwards and are opposite to the outer side surface of a steel rail; and the two hook plates are arranged symmetrically. The hook plates are connected to the lower parts of the axle bearing housings by bolting, welding, riveting, or casting and located above the railway steel rail. When the railway vehicle derails, two wheels of the railway vehicle are disengaged from the steel rail so that the overall railway vehicle deflects towards one side, in such a situation, the anti-rollover device disclosed by the invention can hook the outer side surface of the steel rail so that a railway vehicle body is remained in a state of being perpendicular to the steel rail to ensure that a rollover accident is prevented effectively by means of a reacting force of the steel rail against the wheels, and loss caused by the accident is reduced; no matter how the railway vehicle deflects horizontally after derailing, the anti-rollover device can play a role in locating and preventing rollover; and the anti-rollover device further protects the steel rail well and is safe and reliable.

Description

technical field [0001] The invention relates to an anti-overturning device on a railway rail vehicle, which prevents the whole vehicle from overturning and rollover accidents after the railway vehicle goes off-line and falls off the track. Background technique [0002] At present, my country's railway vehicles are all committed to preventing the occurrence of serpentine instability and derailment accidents, but there are no effective preventive measures for preventing vehicle overturning and rollover after derailment. Contents of the invention [0003] The invention provides an anti-overturning device for a railway vehicle capable of preventing the vehicle from overturning and rollover under the condition that the vehicle goes off-line and falls off the track. [0004] The technical solution of the present invention is that the device is a hook plate arranged at the bottom of the axle bearing box of the railway vehicle, and one end of the hook plate has a hook. [0005] T...
