Abstract

The invention discloses a truck bottom opening and closing device and a truck. The truck bottom opening and closing device comprises a bottom plate frame structure and a bottom plate, a front-back telescopic device is arranged on one side of the bottom plate frame structure, and a telescopic section of the front-back telescopic device is arranged to be capable of driving the bottom plate to move front and back along the bottom plate frame structure; the bottom plate is provided with an automatic locking device, the automatic locking device comprises a lock cylinder fixed on one side of the bottom plate and a lock tongue matched with the lock cylinder, and the automatic locking device further comprises an elastic device for pressing the lock tongue into the lock cylinder. According to the truck bottom opening and closing device, the truck bottom can be automatically opened.

Description

technical field [0001] The invention relates to a truck bottom opening and closing device and a truck. Background technique [0002] Railway transportation has always been an important mode of bulk cargo transportation, and the bulk cargo is mainly coal, ore, grain crops and other types. At present, whether it is railway transportation or road transportation, most of the trucks do not have the ability to independently load and unload goods. With the concept of cost reduction, efficiency increase and lean saving, the loading and unloading of trucks has gradually become automated, and the automatic loading technology of vehicles depends on the configuration of the vehicle itself. [0003] Unloading of bulk cargo is usually done through bottom doors at the bottom of the wagon. At present, the bottom door of a truck usually directly welds the bottom door panel and other accessories to the reserved opening at the bottom of the truck through combination, which can only be operat...
