Automatic correction device for lateral inclination of machine body of coal mining machine

Abstract

The invention discloses an automatic correction device for lateral inclination of a machine body of a coal mining machine. The automatic correction device comprises an inclination angle detecting unit, a lateral inclination inhibition mechanism and a control box, wherein the inclination angle detecting unit is used for performing real-time detection on the inclination angle of the gravity center of the machine body of the coal mining machine to be corrected; the lateral inclination inhibition mechanism can synchronously and forwards move along with the machine body of the coal mining machine to be corrected; the control box is arranged in a cab of the coal mining machine to be corrected; a data processor and a first wireless communication module are arranged on a first electronic circuit board of the control box; a machine body declination warning unit is arranged on the outer side wall of a box body; the lateral inclination inhibition mechanism comprises a vertical support frame, a walking mechanism, an upper jacking hydraulic cylinder and a lower jacking hydraulic cylinder; the walking mechanism is arranged at the bottom of the vertical support frame; the upper jacking hydraulic cylinder is arranged at the upper part of the inner side of the vertical support frame; the lower jacking hydraulic cylinder is arranged at the lower part of the inner side of the vertical support frame; and a downwards pulling hydraulic cylinder is arranged right under each of the upper jacking hydraulic cylinder and the lower jacking hydraulic cylinder. The automatic correction device has the advantages that the structure is simple; the design is reasonable; the installation, the distribution, the use and the operation are simple and convenient; the use effect is good; and the machine body of the coal mining machine generating declination can be automatically corrected in time according to the inclination angle of the machine body of the coal mining machine.

Description

technical field [0001] The invention belongs to the technical field of application of coal shearers, and in particular relates to an automatic correction device for the side tilt of a coal shearer fuselage. Background technique [0002] A coal shearer is a coal mining machine that breaks coal with a rotating working mechanism and reloads the broken coal into a conveyor or other transportation equipment. It is one of the key and indispensable equipment in coal mining machines. , plays a vital role in the entire coal mining process. The mechanism and function of the shearer itself are relatively complex. It is a large and complex system integrating machinery, electricity and hydraulic pressure, and the working environment is harsh. It is affected by the geological environment of the coal mining area and the geographical environment of the coal mining roadway where it is located. Larger, once the shearer breaks down in the actual working process, the entire coal mining work wi...

Problems solved by technology

In the actual use process, the smooth shoes of the shearer are prone to wear and tear, and the wear of the smooth shoes will cause the shearer to tilt to the coal wall side. Due to the deflection of the center of gravity, the guide slide shoes will be lifted, which will not only wear and lift the teeth The part of the rack also affects the meshing of the rack wheel. In severe cases, the shearer will fall off the track. At this time, the bearing of the rack wheel is also easily damaged.

At present, there has not been an automatic correcting device for the side tilt of the shearer body that is simple in structure, reasonable in design, easy to use, and good in use, and can automatically correct the deflected coal mining machine according to the inclination angle of the body of the shearer. The fuselage of the aircraft can be corrected in time, thereby effectively reducing or even avoiding accidents after the center of gravity of the fuselage tilts due to severe wear of the smooth boots
