Railway vehicle window and assembly and disassembly method thereof

Abstract

The invention relates to a railway vehicle window and an assembly and disassembly method thereof. Processes of drilling, tapping and the like for a vehicle are not required, hollow glasses and window frames are preassembled to be an integrated structure and are fastened to be a whole through bolts and a fixing frame, a direct type installation from vehicle body inner side and a disassembling and a replacement from inner and outer sides can be achieved, and the rapid, simple and direct installation, disassembling and replacement can be achieved. The railway vehicle window comprises the hollow glasses and the window frames, the hollow glasses and the window frames are preassembled to be the integrated structure, and sealing gums are filled between the hollow glasses and the vehicle body. The fixing frame is installed on the inner side of the vehicle body in a fastening mode, and the fixing frame is connected with the window frames through the bolts. During a specific installation, the window frames and the fixing frame are fastened to be a vehicle window whole beforehand and are wholly installed on the vehicle body from the interior of the vehicle, and then the fixing frame is installed on the inner side of the vehicle body in a fastening mode. During disassembly, the sealing gums can be removed from the outer side of the vehicle body, the bolts of the fixing frame can be disassembled from the inner side of the vehicle body, at the moment, longitudinal front and rear fastening structures of the window frames and the hollow glasses are removed, and the window frames and the hollow glasses are merely required to be outwards pushed out. During replacement, a new whole of window frames and hollow glasses is installed into the vehicle body from the outer side of the vehicle body, and the window frames are connected with the fixing frame through fixing bolts on the inner side of the vehicle body.

Description

technical field [0001] The invention aims at optimizing and improving the window structure of rail vehicles to realize the operation method of fast installation, disassembly and replacement, and belongs to the field of mechanical manufacturing. Background technique [0002] The rapid development of domestic rail transit has correspondingly put forward higher technical standards for the design and use of car body related accessories. Windows are installed on the side of the rail vehicle body to allow passengers to look out. [0003] There are basically two kinds of window installation and dismounting methods adopted by existing rail vehicles, namely, the loading and unloading methods on the outside of the car and on the inside of the car. When installing the car window, it is necessary to gradually drill and tap the existing car, remove aluminum chips, and repeatedly adjust the flatness of the car window and the outer surface of the car body. Not only the labor load of on-s...

AI Technical Summary

Problems solved by technology

[0004] When disassembling, repairing and replacing windows, it is usually necessary to remove the inner wall panel from the inside of the car body, which is very cumbersome and time-consuming

If the outside of the car is replaced, it is also necessary to remove the sealant between the window and the steel structure of the car body, as well as the structural glue between the glass and the aluminum frame of the window. The operation process is also quite time-consuming and laborious, and it is not easy to control the car. The flatness and smoothness of the external surface of the window and the car body are easy to cause problems such as deformation of the window frame
