Description

Locking device of side wall and side top plate

Technical Field

The utility model relates to a rail transit technical field, concretely relates to locking device of side wall and side roof.

Background

With the acceleration of the urbanization process of China, urban population increases year by year, and the pressure of urban public transportation is increasing day by day. In recent years, underground railways and rail transit equipment have been developed greatly, subways have become important transportation tools for people in various big cities during traveling, and great economic and social benefits are achieved. With the increase of subway vehicle orders, vehicle design tasks are also obviously increased, so that higher requirements are put forward on the design quality and the design speed of the vehicle. Whether the design quality of the interior of the vehicle is over-concerned with the safety of passengers and the external appearance of the vehicle, and the fit clearance of the interior parts of the vehicle is a key factor influencing the design quality of the interior of the vehicle, so that the research on how to effectively adjust the assembly clearance between the interior parts has great significance.

As shown in fig. 1, the side roof panel 1 is generally hinged to a vehicle body, and is used for laying electric structures such as cables. The lock is fixed on the side top plate 1, the lap plate 4 extending towards the side top plate 1 is arranged on the inner side surface of the side wall 3, and when the vehicle normally runs, the lock tongue 21 of the lock is lapped on the lap plate 4, so that the side top plate 1 is locked at the closing position. When needing to overhaul, unblank and rotate spring bolt 21 to break away from lapping plate 4, break off with the fingers and thumb with the force with the side roof 1, can open side roof 1 and carry out the maintenance of electric structure.

Because all there is the error in the vehicle manufacturing and the home-made of assembly, when the vehicle assembly, there is the clearance between spring bolt and the overlap joint board, and the vehicle goes in-process side roof and can take place to rock, and the potential safety hazard is big. At present, the clearance adjustment is generally eliminated by welding or bonding cushion blocks with certain heights. However, the filling manner of the cushion block has two disadvantages: 1. as the cushion block generally requires wear resistance, the cushion block is generally in a solid structure, which can increase the weight of the whole vehicle and influence the running speed of the vehicle. 2. The height dimension of the cushion block is fixed, the gap between the side top plate and the side wall of different carriages cannot be flexibly adjusted, if deviation is generated in the assembly process of manufacturing or technology, the cushion block can be manufactured or assembled again, namely, the cushion block has no universality, and therefore great workload is increased for design and manufacturing personnel, and the design period is influenced.

SUMMERY OF THE UTILITY MODEL
