Abstract

A support device for the roof of a coal mine working face disclosed by the invention comprises a left fixed base and a right fixed base, the left fixed base is located in front of the right fixed base, the left fixed base and the right The inner side of the side fixed base is provided with a plurality of base threaded holes, the left fixed base and the right fixed base are movably installed with fixed claw bolts through the base threaded holes, and the upper outer surface of the fixed claw bolts is fixed with anti-skid bolts head. A support device used for the roof of a coal mine working face according to the present invention can adjust the support height and fixed angle of the support device, facilitate the use of support and fixation on different grounds and occasions, and firmly position the device to prevent There is a risk of displacement of the supporting device after long-term use, and the supporting area of ​​the supporting device can be adjusted, which is inconvenient for supporting and fixing coal mine working faces of different sizes.

Description

technical field [0001] The invention relates to the field of support devices, in particular to a support device used for the roof of a coal mine working face. Background technique [0002] The supporting device of the roof of the coal mine working face is used in the coal mine to support and reinforce the working face of the coal mine. It is widely used in coal mining and is the main support and fixed structure of the coal mine. With the continuous development of society, As the main energy material for power generation and heating, coal mines have gradually increased people's demand for coal mine mining, and at the same time, the demand for support devices for the roof of coal mine working faces has also gradually increased. The disadvantages of this method cannot meet the needs of the current stage of use; when the support device of the roof of the coal mine working face is used, the height and fixed angle of the support device cannot be adjusted, which is inconvenient for...
