The protection device comprises a forepoling, a hose and hanging mechanisms, each hanging mechanism is fixedly connected with the forepoling, the hose sequentially penetrates through each hanging mechanism, and the hanging mechanisms are fixedly connected with the forepoling. Each hanging mechanism comprises a mounting groove, a first side plate, a second side plate, a sliding block, a first lead screw, a second lead screw, a first limiting ring and a second limiting ring, the mounting groove is fixedly connected with the forepoling, the sliding block is in sliding connection with the first side plate, the second lead screw is fixedly connected with the sliding block, and the first limiting ring and the second limiting ring are in threaded connection with the second lead screw. And the outer surface walls of the second lead screws are sleeved with the first lead screws. According to the arrangement of the structure, the hose can be hung, meanwhile, adjustment can be conducted according to different sizes of the hose, and the hoses of different sizes can be hung.
Description
technical field [0001] The invention relates to the technical field of construction auxiliary equipment, in particular to a protection device for a gantry undercutting protection device for a drilling site extraction hose. Background technique [0002] At present, for gas extraction in the air tunnel drilling site of fully mechanized mining face, it is necessary to draw out multiple 4-inch hoses and connect them to the upper gas extraction main pipe. Moving the front support often causes the top beam to squeeze the extraction pipe, which affects the gas extraction effect and brings great hidden dangers to the safe production of the working face. [0003] In the prior art, through the middle position of the two rows of steel strips on the roadway roof at the exit of the high-level drilling field, the air pick is used to cut the groove. The cutting size is: width 500mm × depth 300mm, and the length is the actual width of the roadway. After construction, connect the 4-inch ext...
