Abstract

The invention discloses a protection device for a mining dump truck rear-axle test bed. The protection device is characterized by comprising a left protection cover assembly and a right protection cover assembly which are arranged symmetrically, wherein each protection cover assembly consists of a protection cover framework and a protection net arranged on the framework; a lower beam of the framework is connected with a base in a slidable manner through a sliding component sleeved on the base; the base is fixedly connected with a test bed base; and a limiting structure is arranged between theframework and the base in a matched manner. By arranging the left protection cover assembly and the right protection cover assembly which are connected with the base in a slidable manner through the sliding component, the protection device can translate in a slidable manner and turn relative to the base so as to effectively exert the function of protecting the safety of the test bed and avoid accidents.

Description

technical field [0001] The invention relates to a protective device, in particular to a protective device for a rear axle test bench of a mining dump truck. Background technique [0002] A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting, also known as a dump truck. According to different driving modes, it is also divided into 6×4, 8×4 and semi-trailer dump trucks. According to different uses, it is also divided into ① mine dump truck, used to transport coal mines and sand and gravel; ② sanitation and green dump truck, used to transport garbage, etc. According to the direction of the compartment turning, there are also front-lift and side-turning dump trucks. Mining dump truck is a mining transport vehicle, which belongs to one of the mining equipment and is mainly used for the transportation of ore and other bulk materials in the mine. [0003] The drive axle of the mine dump truck is the key assembly of the mine dump truck. I...
