Non-guide foot of coal cutter

Abstract

The invention provides a non-guide foot of coal cutter. The non-guide foot comprises a non-guide foot body, wherein two side surfaces, which are contacted with two sides of a scraper conveyor cogged rail, of the non-guide foot are a plate type structure, wear-resistant plate mounting slots are formed in two ends of the non-guide foot body, wear-resistant devices are arranged in the wear-resistant plate mounting slots and are positioned by baffles which are arranged in the ends of the non-guide foot body, each wear-resistant device consists of wear-resistant plates and springs, grooves are formed in the wear-resistant plate, one ends of the spring are arranged in the grooves of the wear-resistant plate, grooves corresponding to those on the wear-resistant plates are formed at the wear-resistant plate mounting slots on the non-guide foot body, and the other ends of the springs are arranged in the grooves in the wear-resistant plate mounting slots on the non-guide foot body. According to the non-guide foot, the walking part of the coal cutter can be prolonged, the coal cutting production efficiency can be further increased, the equipment loss and fault rate can be reduced, the change is convenient and the production cost can be lowered.

Description

technical field [0001] The invention relates to a part of a coal mining machine, in particular to a non-guiding sliding shoe of a coal mining machine. Background technique [0002] At present, the traction system of the shearer adopts a two-wheel drive system. The side of the shearer close to the coal wall has two support shoes, and the other side has two guide shoes. Due to the irregular geological structure of the coal field, the thickness and inclination of the coal seam often fluctuate in a mining area. During the working process of the coal shearer, the force on the traveling part is extremely complicated, and various failures often occur in the traveling mechanism, such as broken teeth of the traveling wheel. , Abnormal wear of guide shoes, etc., both affect production and reduce the service life of equipment, causing great losses to production enterprises, increasing coal mining costs in disguise, and affecting the normal development of the national economy. At prese...

Problems solved by technology

Due to the irregular geological structure of the coal field, the thickness and inclination of the coal seam often fluctuate in a mining area. During the working process of the coal shearer, the force on the traveling part is extremely complicated, and various failures often occur in the traveling mechanism, such as broken teeth of the traveling wheel. , Abnormal wear of guide shoes, etc., which not only affect production but also reduce the service life of equipment, causing great losses to production enterprises, increasing coal mining costs in disguise, and affecting the normal development of the national economy

At present, a wear-resistant layer is welded on the inner side of the guide shoe. When the guide shoe fails to work normally, the guide shoe is removed, re-surfacing or scrapped directly. It takes a long time for replacement and maintenance, which seriously reduces the coal mining efficiency
