Abstract

The invention relates to mining machinery, and particularly relates to a side support device for a coal mining machine, aiming to solve the problem that the existing support device can not effectively inhibit the back and forth vibration of the coal mining machine. In order to achieve the purpose, the side support device comprises a first hydraulic cylinder, a second hydraulic cylinder, a third hydraulic cylinder, a fourth hydraulic cylinder, a first support base and a second support base, wherein the first hydraulic cylinder and the second hydraulic cylinder are arranged on the first side of the coal mining machine, the third hydraulic cylinder and the fourth hydraulic cylinder are arranged on the second side of the coal mining machine, the first support base is connected with the outer side ends of the first hydraulic cylinder and the second hydraulic cylinder, and the second support base is connected with the outer side ends of the third hydraulic cylinder and the fourth hydraulic cylinder. When the side support device works, the first hydraulic cylinder, the second hydraulic cylinder and the first side of the coal mining machine can form a triangular structure, the third hydraulic cylinder, the fourth hydraulic cylinder and the second side of the coal mining machine can also form a triangular structure, and the first support base and the second support base are abutted against the side wall of a coal mine tunnel. The side support device with the structure can be used for effectively inhibiting the back and forth vibration and the left and right vibration of the coal mining machine due to cutting.

Description

technical field [0001] The invention relates to mining machinery, in particular to a side support device for a coal mining machine. Background technique [0002] Shearer is a large comprehensive machine used to replace manpower in coal mining operations. The use of coal mining machines to mine coal can reduce physical labor, improve safety, and achieve the goals of high output, high efficiency, and low energy consumption. The shearer will generate a lot of vibration during operation. This vibration will not only affect the stability of the shearer body, but also reduce the shearer parts - especially the cutting head / cutting tooth / roller. Service life, which in turn affects the production efficiency of coal mining operations. [0003] A technical solution to this problem already exists in the prior art. For example, CN201090216Y describes a horizontal side support stabilization device for a shearer, which includes two oil cylinders respectively arranged on both sides of th...
