Abstract

The invention provides a dumper. The dumper comprises a vehicle body and wheels mounted on the vehicle body. The dumper further comprises at least one driving unit, wherein the driving unit comprises at least one oil cylinder and a crank; the crank comprises a spindle neck and a connecting rod shaft neck; the crank is rotatably mounted on the vehicle body of the dumper through the spindle neck; the oil cylinder is mounted on the vehicle body in a swinging manner; the piston rod of the oil cylinder is connected with the connecting rod shaft neck; the oil cylinder can drive the crank to rotate; the crank is fixedly connected with the wheels; and the oil cylinder can drive the wheels to rotate through the crank. According to the technical scheme of the invention, the crank is driven by a hydraulic force, and rotary power is output. The dumper has the obvious advantages of large output torque, stable operation, no un-balance loading, full-stroke acting, simple structure and the like, is convenient to control, space-saving and easy to implement.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a dump truck. Background technique [0002] Mineral resources such as iron and coal are the basic materials and energy minerals necessary for the development of the world economy, and their mining and transportation are closely related to the efficient development and utilization of mineral resources. The traditional mechanical transmission mechanism adopts mechanisms such as clutch, transmission, transmission shaft, main reducer and differential. With the continuous expansion of mine scale, higher requirements are put forward for the tonnage, performance and quantity of mining dump trucks, and traditional mechanical transmission dump trucks can no longer meet the actual needs. Because the mining dump truck needs a large driving force, the transmission structure is very heavy and bulky. [0003] With the continuous expansion of the scale of large-scale open-pit m...
