Vehicle body sliding top cover

Abstract

The invention relates to the technical field of rail transit vehicle bodies and particularly relates to a vehicle body sliding top cover. The vehicle body sliding top cover comprises a top cover body and an exterior skirt plate, wherein a sliding groove is formed in the exterior skirt plate, screw holes are distributed in the sliding groove, the two sides of the top cover body are matched with the sliding groove, holes corresponding to the sliding groove in position are formed in the two sides of the top cover body, and the top cover body is installed on the exterior skirt plate; the top cover comprises an upper-layer plate and a lower-layer plate, reinforcing ribs are lined between the upper-layer plate and the lower-layer plate, reinforcing ribs are also arranged below the lower-layer plate, and the upper-layer plate and the lower-layer plate are made of FRP; an inspection opening is formed in the top cover, a matched inspection cover plate is arranged on the inspection opening, and the inspection cover plate is hinged to the top cover through a hinge; the inspection cover plate is provided with a bayonet, and the bayonet is connected with the top cover through a fastener. The vehicle body sliding top cover top cover is convenient to install and low in failure rate, the top cover can slide on the apron board through the sliding grooves, and short-time overhaul and maintenance can be achieved when equipment overhaul is conducted on the tops of bullet trains, subways and other train bodies.

Description

technical field [0001] The invention relates to the technical field of rail transit car bodies, in particular to a car body sliding top cover. Background technique [0002] When the electrical equipment installed in the head space of existing rail transit vehicles such as bullet trains and subways needs to be overhauled, it is often necessary to use hoisting equipment to assist in hoisting the traditional fixed roof, which is often time-consuming and laborious, and is prone to bumping and deformation etc., which affect the appearance and service life of the top cover, the narrow space of the car body and the shortage of operators are the difficulties that limit the maintenance efficiency, and the safety is also low. Therefore, a new type of top cover structure is urgently needed to save maintenance time , Reduce manpower input and improve safety. Contents of the invention [0003] The object of the present invention is to provide a sliding top cover for a vehicle body in ...
