Railway vehicle and pull-out unlocking type equipment box cover secondary protection device thereof

Abstract

The invention discloses a railway vehicle and a pull-out unlocking type equipment box cover secondary protection device thereof. The pull-out unlocking type equipment box cover secondary protection device comprises a mounting seat, a mounting cylinder, a protection plate and an elastic component, wherein the mounting seat is used for being connected with a frame of the periphery of an equipment box cover; one end of the mounting cylinder is fixedly connected with the mounting seat and the other end of the mounting cylinder is provided with an end cover which is provided with an opening; the protection plate comprises a plate body part which compacts the equipment box cover and a spindle part which is connected with the plate body part; the spindle part extends into the mounting cylinder via the opening, and the part, extending into the mounting cylinder, of the spindle part is provided with an elastic component propping part; one end of the elastic component is propped against the elastic component, and the other end of the elastic component is propped against the end cover. Due to the adoption of the arrangement, the pull-out unlocking type equipment box cover secondary protection device of the railway vehicle can perform secondary protection on the equipment box cover of the railway vehicle, and can effectively prevent the equipment box cover from falling off.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle and a secondary protection device for a pull-out and unlockable equipment box cover thereof. Background technique [0002] In the prior art, the equipment box of the rail vehicle is suspended at the lower part of the vehicle body. Due to various complicated working conditions when the rail vehicle is running, the equipment box suspended under the vehicle is subjected to different degrees of shock and vibration. If these shocks and vibrations destroy the original lock on the equipment box cover The device and the cover of the equipment box will most likely fall off, endangering the operation safety of the rail transit vehicle, resulting in danger. [0003] Therefore, how to prevent the case cover of the equipment box from coming off has become an important technical problem to be solved by those skilled in the art. Contents of the invention [0004] The in...
