Rail vehicle head openable and closed front cover

Abstract

The invention relates to a rail car head front cover capable of being opened and closed. The front cover comprises a left front cover and a right front cover which are arranged symmetrically, an opening and closing mechanism used for driving the left front cover and the right front cover, a locking device, and a mounting seat. The mounting seat is fixed on a car head bottom frame, the opening and closing mechanism and the locking device are fixed on the mounting seat, and the left front cover and the right front cover are turned to the outer side of the front end of a car body after being opened. The front cover is simple in structure and is turned to the outer side of the car body, the entire appearance effect is fine, the left front cover and the right front cover are free of occupying the limited space in the car head after being opened, and interferences with other structures in the car head are eliminated during opening and losing; meanwhile, head space occupied by the opening and closing mechanism is reduced effectively, and the front cover is particularly adaptable to a rail car with a short and flat head surface and small head inner space.

Description

technical field [0001] The invention relates to a front cover of a rail vehicle head, in particular to an openable and closable front cover of a rail vehicle head, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] When the rail vehicle is connected or rescued, it is necessary to connect the coupler. In order to meet the requirements of the vehicle connection, the front end of the rail vehicle head adopts a split-type automatic opening and closing front cover structure. The front cover is driven by the opening and closing mechanism. When the vehicle is running normally, the front cover is closed, and when needed, the front cover is opened left and right to leave the necessary space for the coupler to hang, and the coupler is automatically unlocked and extended and connected to realize reconnection or pairing between trains Rescue the broken down train. [0003] For example, the Chinese patent No. 200820207216.5 discloses a front ...

AI Technical Summary

Problems solved by technology

[0004] At present, after the front cover of the train is opened, the structural form embedded in the car body as described in the above-mentioned patent is adopted. Due to the narrow and irregular internal space of the car head, this structural form not only occupies the limited space of the head of the rail vehicle. In addition, it is necessary to ensure that the front cover does not interfere with other structures inside the front of the car when it is opened and closed, which makes the structure of the front cover opening and closing mechanism complex and the cost is relatively high.
