Abstract

The invention relates to the technical field of wagon manufacturing, in particular to a device for controlling a bottom door to be opened and closed. The device comprises a locking mechanism and a touch arm mechanism, wherein the locking mechanism is fixed to a chassis of a wagon body and comprises a locking hook; the touch arm mechanism is fixedly connected with a transmission shaft of a bottom door opening and closing mechanism of the wagon body and comprises a touch arm body, a first idler wheel, a second idler wheel and a locking lift; the first idler wheel and the locking lift are both arranged at the first end of the touch arm body; the second idler wheel is arranged at the second end of the touch arm body. Through cooperation of the locking mechanism and the touch arm mechanism, opening and closing of the bottom door can be achieved when the wagon runs in any direction, the bottom door opening and closing mechanism is prevented from losing efficacy when the wagon runs, and reliability of the vehicle bottom opening and closing mechanism in the running process is ensured.

Description

technical field [0001] The invention relates to the technical field of railway wagon manufacturing, in particular to a device for controlling the opening and closing of a bottom door. Background technique [0002] Most of the existing railway hopper cars use a touch-type bottom door opening and closing mechanism. Due to the limitation of the touch arm, the existing touch-type bottom door opening and closing mechanism can only realize the opening of the bottom door in a single running direction specified by the vehicle. If the vehicle is driven in the reverse direction, the opening and closing mechanism of the bottom door will interfere with the ground contact device, which will affect the normal operation of the vehicle. This type of touch-type bottom door opening and closing mechanism relies on the "over dead point" of the linkage mechanism to lock in the closed state. During the driving process of the vehicle, due to the vibration of the vehicle, there is a situation that ...
