Hydraulic lifting tail-board mechanism

Abstract

The invention discloses a hydraulic lifting tail-board mechanism which comprises a hydraulic drive unit and a lifting tail-board unit connected with the same. The hydraulic drive unit is connected with the lifting tail-board unit through a connecting rod unit. The hydraulic drive unit is disposed at the rear of a car cargo tank and drives the connecting rod unit to retract as being close to the car cargo tank and to extend as being far away from the car cargo tank. The connecting rod unit is disposed at the rear of the car cargo, is connected with the lifting tail-board unit and drives the lifting tail-board unit to move up when the connecting rod unit retracts and to move down when the connecting rod unit extends. Lifting of the lifting tail-board unit can be achieved by driving the connecting rod unit by the hydraulic drive unit, structure is simple, weight is light, and production cost is low; and manufacture process is simple, the hydraulic lifting tail-board mechanism can be additionally mounted on the original car in conventional way, mounting and demounting of cargoes can be achieved by operating a control unit by one person, and accordingly labor intensity is lowered and operation efficiency of a truck is improved.

Description

technical field [0001] The invention relates to a car body structure, in particular to a hydraulic lifting tail plate mechanism for transferring goods from the ground to the bottom plate of the car cargo box or transporting the goods in the car cargo box to the ground. Background technique [0002] Existing cars with flat cargo boxes usually require multiple operators to manually move the cargo from the cargo box to the ground or from the ground to the cargo box when loading and unloading the cargo. Great intensity. [0003] In the prior art, there are also mechanisms for automatically lifting and lowering goods on flat cargo boxes, most of which are complex in structure, significantly increase the carrying weight of the vehicle, and reduce the operating efficiency of the truck. Contents of the invention [0004] (1) Technical problems to be solved [0005] The technical problem to be solved by the invention is to reduce the labor intensity of loading and unloading goods...
