Abstract
The utility model relates to a locomotive roof cover installation structure which comprises a bolt and a nut and is characterized in that an installation rail is fixed at the top end of a locomotive body side structure, an opening is arranged at the top surface of the installation rail, an installation hole matched with the opening at the top surface of the installation rail is arranged at the corresponding position of a roof cover, the bottom of the bolt is arranged in the installation rail, and the top of the bolt penetrates through the installation hole of the roof cover and is fastened at the outer end of the roof cover by the nut. The locomotive roof installation structure solves the problem that the bolt and the nut are difficult to be aligned in position when the roof cover is installed, and has the advantages of being fast and convenient.
Description
Technical field
The utility model relates to a kind of mounting structure of locomotive header.
Background technology
The mounting structure commonly used of locomotive header is, welded nut positioning seat on car body side structure, and configuration activities nut in it with the alignment of a hole nut seat on the top cover, is screwed into bolt and firm when top cover is installed again from top cover top.For the sealing effectiveness of top cover, usually each top cover around be distributed with more than 20 mounting hole, need repeatedly adjust the position when top cover is installed so that all bolts are aimed at nut, relatively waste time and energy.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of locomotive header mounting structure is provided, and bolts and nuts are aimed at the problem that is difficult for when solving the top cover installation, realize the Fast Installation of top cover.
The technical solution of the utility model is, a kind of locomotive header mounting structure, comprise screw bolt and nut, it is characterized in that, car body side structure top is fixed with the mounting rail that end face is provided with opening, and the relevant position on top cover is provided with the mounting hole that cooperates with mounting rail end face opening, and the bolt bottom places in the mounting rail, and the bolt top is passed the top cover mounting hole and is fastened on the top cover outer end by nut.
Described bolt is the T font, utilizes the matching relationship between T font bolt and the mounting rail lozenges, and T font part is spacing in mounting rail.
Be provided with packing ring between described nut and the top cover.
Welded and installed rail on car body side structure and crossbeam is offered waist shape mounting hole simultaneously around top cover.Prepackage T type bolt, packing ring and nut on top cover, only need rotate T type bolt and its head is fallen in the mounting rail during top cover lifting, because of the head of T type bolt is roughly an oblong, its width is littler than the groove width of mounting rail, so T type bolt is easy to fall into mounting rail, T type bolt is revolved again and turn 90 degrees, utilize cooperating between T type bolt and the mounting rail lozenges, fastening nut can install top cover.
As known from the above, the utility model has solved the problem of the difficult aligning in bolts and nuts position when top cover is installed as a kind of locomotive header mounting structure, has advantage fast and easily.
