Problems solved by technology

However, after the side door is fixed by the locking piece, the force exerted by coal on the side door makes it difficult to open the locking piece. The usual way is to open the locking piece by knocking, which is time-consuming and laborious, and often causes the locking piece to be broken. and the deformation of the side door of the carriage, the safety of the operator cannot be guaranteed

Abstract

A device for assisting in opening a railway wagon side door comprises a shell, and a clamping body and a mounting plate arranged at the front end and the rear end of the shell, and an electric push rod mechanism is arranged in the shell; the clamping body is provided with a base and a rear support block positioned at the rear end of the base, the front of the base is provided with a groove, so that a front support block is formed on the base, a through hole allowing a push rod of the electric push rod mechanism to extend out of is formed in the rear support block, and a filling block which is detachably connected onto the front support block is arranged in the groove. According to the invention, a certain gap is formed between a locking part of a side door and a fixing part of the side door of the railway coal wagon through exerting thrust, so that the locking part can be opened, the side door of the railway wagon can be quickly opened, the use is flexible and convenient, efficiency is high, the labor intensity of workers is reduced, a further guarantee of safe production is realized, and the deformation of a locking mechanism and the wagon side door caused by beating is prevented.

Description

technical field [0001] The invention relates to an auxiliary device for opening a side compartment door of a railway freight car. Background technique [0002] Railway wagon is an important means of transportation. It has the advantages of large capacity, high speed, low cost, and low energy consumption. It has always been the main mode of coal transportation. Among the freight volume of main railway lines, it accounts for 50% of the total railway cargo transportation. %above. [0003] Gondola wagon is a freight car with end and side walls but no roof. During the process of transporting coal, the coal covers the entire compartment. To ensure the safety of the cargo during transport, the side compartment doors must be fixed with locking pieces. However, after the side door is fixed by the locking piece, the force exerted by coal on the side door makes it difficult to open the locking piece. The usual way is to open the locking piece by knocking, which is time-consuming and l...
