Problems solved by technology

[0003] 1. There is no automatic opening and closing device for the rear door, and it is necessary to manually open the rear door to unload the material. In this case, the labor intensity is high and the work efficiency is low.
[0004] 2. The rear door is equipped with an opening and closing device, but the mechanism is exposed. During the reversing process, the actuator of the opening and closing mechanism is likely to be damaged, which makes the opening and closing mechanism invalid and the work is unreliable.

Abstract

The invention relates to an automatic opening and locking mechanism for the carriage backdoor of a trackless rubber-tyred car. The automatic opening and locking mechanism comprises a specially designed hydraulic control system and the specially designed hidden carriage backdoor, and is mainly used for automatically opening and locking the backdoor of an undermine ejector dumping machine. The automatic opening and locking mechanism has the characteristics that the operation intensity of personnel is reduced, the misoperation is reduced, the working efficiency is improved, execute components are hidden on the inner side of a carriage, so that the execute components are protected effectively, and the automatic opening and locking mechanism is compact in structure,, and is firm and durable.

Description

technical field [0001] The invention relates to an automatic opening and closing locking mechanism, in particular to an automatic opening and closing and locking system for a hidden compartment rear door of a mining explosion-proof trackless rubber-tyred vehicle, belonging to the technical field of coal mine transport vehicles. Background technique [0002] At present, it is necessary to use explosion-proof trackless rubber-tyred vehicles to transport materials in the coal mine roadway. Since the coal mine is located in an underground narrow roadway, the driver has two disadvantages when using the push-back unloading vehicle: [0003] 1. There is no automatic opening and closing device for the rear door, and it is necessary to manually open the rear door to discharge materials. In this case, the labor intensity is high and the work efficiency is low. [0004] 2. The rear door is equipped with an opening and closing device, but the mechanism is exposed, and the actuator of th...
