An integrated device that facilitates the walking and support of coal mining machines

Abstract

The invention discloses an integrated device facilitating travelling and supporting of a coal cutter. The integrated device comprises an integrated base, sliding grooves are symmetrically formed in the surfaces of the two ends of the integrated base, one ends of the sliding grooves are slidably connected with sliding connecting columns, and a coal cutter mounting seat is fixedly mounted at the topends of the sliding connecting columns. The integrated device is scientific and reasonable in structure and safe and convenient to use, dustproof protection can be conducted through a dustproof beltconnected to one ends of the sliding connecting columns, the situation that coal slag and dust enter the sliding grooves and a mounting cavity during operating of the coal cutter is avoided, the dustproof belt can be collected through a flat spiral spring connected to the outer side of a dustproof belt collecting roller and a limiting plate, by plugging a connecting round rod at one end of a fixedconnecting rod into a fixing hole, a limiting protruding block mounted at one end of the connecting round rod in an embedded mode enters a limiting groove in the fixing hole, the position of the connecting round rod is limited and fixed, by pressing a loosening button, the fixed connecting rod can be taken out of the fixing hole quickly, and the fixed state can be quickly released.

Description

technical field [0001] The invention relates to the technical field of welding devices, in particular to an integrated device that facilitates the walking and supporting of a coal mining machine. Background technique [0002] The shearer is one of the main equipment of the complete mechanized mining equipment. The shearer is evolved from the shearer. The shearer is a large and complex system integrating machinery, electricity and hydraulic pressure. The working environment is harsh. If A failure will lead to the interruption of the entire coal mining work, resulting in huge economic losses. The coal mining machine is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve high output. For the purpose of high efficiency and low consumption, the shearer needs to be moved and fixed many times during the coal mining process. However, when the existing shea...

Problems solved by technology

[0003] The present invention provides a technical solution, which can effectively solve the problem that the external coal and dust etc. are easy to fall inside the mechanism mentioned in the above background technology, causing the transmission gear assembly inside the mechanism to be damaged, affecting the use, and the existing coal shearer is walking When used with the support mechanism, the shearer cannot be well fixed and supported, resulting in a certain degree of displacement of the shearer during the coal mining process, which affects the efficiency of coal mining
