The embodiment of the invention discloses a frictional wear test device for a guide sliding shoe, which comprises a base, and a horizontal traction mechanism and a load loading mechanism are mounted on the base; the horizontal traction mechanism comprises a traction piece, a grinding pair and a sliding rail; the sliding rail is arranged in the moving direction of the traction piece, the grinding pair is arranged on the sliding rail, and the moving end of the traction piece is connected with the grinding pair; and the load loading mechanism is located on the outer side of the sliding rail and used for loading loads on the guide sliding shoes. When the guide sliding shoe is tested, the guide sliding shoe is connected with the load loading mechanism, the grinding pair is attached to the bottom of the guide sliding shoe, firstly, the load loading mechanism is used for loading a load with a preset load capacity on the guide sliding shoe, then the traction piece is used for driving the grinding pair to slide on the sliding rail in a reciprocating mode, and therefore the grinding pair moves relative to the guide sliding shoe. In this way, a worker can select a proper guide sliding shoe according to the abrasion resistance of the guide sliding shoe.
Description
technical field [0001] The invention relates to the technical field of mining machinery, in particular to a friction and wear test device for a guide shoe. Background technique [0002] Mining machinery is directly used for mineral mining and enrichment and other operations. Among them, the shearer is the most important type of mining machinery, and it is one of the important equipment to realize the mechanization and modernization of coal mine production. [0003] The shearer is composed of cutting part, power part and traction part. The cutting part includes the working mechanism and the reducer, the power part includes the motor and the electrical control box, the traction part includes the guide shoe and the road wheel, etc. The walking of the shearer on the conveyor is realized through the engagement with the pin row of the scraper conveyor. [0004] At present, coal shearers often have pitching coal mining conditions during the coal cutting operation. These two work...
