Embodiment Construction

[0019] The accompanying drawings show an embodiment of the present invention, and the present invention will be further described below in conjunction with the accompanying drawings.

[0020] It can be seen from the accompanying drawings that the present invention is a method and device for sealing a roof cover of a locomotive. The present invention adopts a wide-side sealed locomotive roof sealing method, allowing the entire sealing strip to be compressed and sealed as a whole, and the locomotive roof and the locomotive roof, and the locomotive roof and the locomotive end wall are realized through a wider sealing strip. And the seal between the locomotive end wall and the locomotive roof.

[0021] The device provided according to the method of the present invention is a wide-side locomotive roof sealing structure. 4 Combination structure, wherein, the auxiliary sealing strip 3 is provided between the locomotive roof 1 and the locomotive roof 2, the locomotive roof 1 and the ...

Abstract

The invetnion relates to an engine top cover sealing method and device, adopting a wideside-sealing engine top cover sealing method, making the whole seal tape integrally compressed to seal, and implementing sealing between top covers, between top cover and end wall, and between side wall and top cover by wider sealing tape, where the sealing auxiliaries are mainly composed of sealing tape, side wall, top cover installation beam and top covers, sealing auxiliary sealing tape is arranged between top covers, between top cover and end wall and betweeen side wall and top cover, and they are sealed by the sealing auxiliary sealing tape, and the sealing structure is a sealing tape-integral compressed wideside sealing struture; and the contact area of the sealing tape with the coupled side wall, top cover installation beam and top covers is equal to the top surface area of the whole sealing tape; and the sealing limits the sealing tape compression ratio by the difference between the height of componnet installation guide rail composing sealing auxiliary and that of the sealing tape.

Description

technical field [0001] The invention relates to a sealing method and device for locomotive parts, in particular to a sealing method and device for a locomotive top cover, which are mainly used in various electric locomotives. Background technique [0002] The sealing of the locomotive is very important for the locomotive. If the seal is not good, it will have a great impact on the components of the locomotive, and even cause an electrical short circuit, which may cause an accident. The existing locomotive roof sealing device mainly includes the sealing between the locomotive roof and the roof, the roof and the end wall, and the side wall and the roof (see accompanying drawings 1 to 3), and the existing sealing devices are all It is sealed by forcing a metal edge to press the sealing strip by a thread mechanism, and the sealing strip is in a local compression state with a small contact area. Since the sealing strip is in a partially compressed state, and the compression amou...
