Embodiment Construction

[0040] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0041]The top dead center and bottom dead center of the crank 3 in the present invention means that the crankshaft 2 rotates 180 degrees. If the hydraulic cylinder 1 is arranged up and down, the top dead center of the crank 3 means that the crank 3 rotates to the uppermost position, and the bottom dead center of the crank 3 It means that the crank 3 is rotated to the lowest position. If the hydraulic cylinder 1 is arranged horizontally, the top dead center and bottom dead center of the crank 3 refer to the left and right positions where the crank 3 rotates to the horizontal position.

[0042] Such as figure 1 and figure 2 As shown, a hydraulic drive device preferably provided by the present i...

Abstract

The invention discloses a hydraulic driving device. The hydraulic device comprises a shell and a crankshaft, and additionally comprises at least two hydraulic oil cylinders, at least two detection devices and a controller, wherein each hydraulic oil cylinder is hinged with each crank of the crankshaft, each detection device is used for obtaining the reversing position signal of each hydraulic oil cylinder, and the controller is used for obtaining the signal of each detection device and controlling the hydraulic oil cylinders to work cooperatively. The invention additionally provides a mine dump truck and a hydraulic driving device control method. The hydraulic driving device, the mine dump truck and the hydraulic driving device control method have the advantages of good stability, strong load adaptability and wide speed adjustment range.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a mining dump truck, a hydraulic drive device and a control method. Background technique [0002] The off-highway mining dump truck is a heavy-duty dump truck used in open-pit mines to complete the tasks of rock and earth stripping and ore transportation. Its working characteristics are short distance and heavy load. Because of its super wide shape and excessive total mass, it is not allowed to drive on the road. Off-highway mining dump trucks can be divided into mechanical transmission and electric transmission in terms of driving methods. In recent years, electric drive non-highway mining dump trucks have been widely used in large-scale open-pit mining and transportation due to their simple chassis structure, light and flexible operation, high reliability, and good operating economy. Electric drive is divided into DC drive and AC drive. Due to the relatively high mainten...
