Background
As shown in fig. 1, a cab apron component 3 of a railway vehicle is arranged at the bottom of the vehicle end of two adjacent carriages, the two carriages are connected by a folding shed component 1 along the whole circumferential direction, and a skirt edge component 2 is arranged at the lower part of the folding shed component 1 and above two sides of the cab apron component 3, so as to play a role in shielding. In order to further avoid excessive pollutants falling into the space below the cab apron assembly, the left side and the right side of the cab apron assembly 2 are required to be provided with the enclosing barriers, and the enclosing barriers are wrapped in the skirt edge assembly, so that the problem that the cab apron is extremely difficult to lift once the enclosing barriers are arranged is solved. The lower part of the cab apron assembly 1 is a coupler part for connecting two vehicles, the space below the coupler part and the cab apron assembly 1 needs to be regularly overhauled and cleaned, and for coupler maintenance personnel and windshield bottom space cleaning personnel, the cab apron assembly 1 must be lifted or detached before operation, and the cab apron assembly 1 has an upward opening direction because the bracket assembly 4 for supporting the cab apron assembly 2 is arranged below the cab apron assembly 2. Therefore, when one end of the cab apron component 1 is lifted upwards, the surrounding baffle of the cab apron component 1 can interfere with the skirt edge component 2, the time occupied by lifting the cab apron component 1 is far longer than the time used by the current work, and the total work time is occupied by the cab apron component for the most part. When the whole train is overhauled, the vehicle marshalling is decomposed into a single train, the cab apron components are required to be detached from the train, the same problem is also faced, the upward opening process of the cab apron components is difficult, the working efficiency of maintenance personnel, cleaning personnel and overhauling and disassembling personnel is greatly reduced, and once the operation is poor, the cab apron components are easy to damage.
