Embodiment Construction
[0024] Such as figure 1 , 2 , 3, 4, 5, and 6 show a high-pressure hydraulic seam cutting machine for cutting coal seams, consisting of a frame 1, a continuous steel pipe straightening machine and a pusher 2, a continuous steel pipe multilayer winding reversing mechanism 3, and a continuous steel pipe 4 , Winding drum 5, continuous steel pipe pressing mechanism 6, jet slit drill bit 7, hydraulic valve group 8, drum driving mechanism 9, high-pressure water distribution jacket 10 and other components.
[0025] The four corners of the frame 1 are installed with a slotting machine supporting cylinder 1-1 controlled by a hydraulic valve group 8. The expansion and contraction of the oil cylinder can control the height and elevation angle of the slotting machine. The center of the frame 1 is equipped with a drum rotation shaft 1-2, the winding drum 5 is placed horizontally and can rotate around the drum rotating shaft 1-2 located in the center of the frame. When the winding drum 5 r...

The invention discloses a high-pressure hydraulic cutting machine for cutting coal seams, which relates to a rock drilling machine and solves the problems of the prior art that the driving component can be damaged easily, the drilling position is too low, and the continuous tube length is limited. The high-pressure hydraulic cutting machine is characterized in that the four angles of a rack are provided with hydraulic cutting machine supporting cylinders, a roller rotating shaft is arranged at the center of the rack, and a winding roller is horizontally arranged; a continuous steel tube pushing and straightening machine consist of a connecting tank body, a straightener and a pusher, and a continuous steel tube penetrates into the through holes of the pusher and the straightener; a high-pressure water distribution sleeve consists of a water distribution sleeve disc, a water distribution inner sleeve and a water distribution outer sleeve; the water distribution sleeve disc is provided with a continuous tube multilayer winding reverse mechanism; a roller driving mechanism consists of a hydraulic motor, a gear set and a roller gear ring, the roller gear ring is connected with the winding roller, the hydraulic motor and the gear set are arranged on the water distribution sleeve disc, and the gear set drives the roller gear ring to drive the winding roller to rotate; and continuous steel tube hold-down mechanisms are distributed around the winding roller. The high-pressure hydraulic cutting machine in the invention is used for improving the breathability of hypotonic mineral storage layers, especially the coal seams.
Description
technical field [0001] The invention relates to rock-drilling machinery, in particular to a high-pressure hydraulic seam cutting device which uses high-pressure water jets to cut coal seams and improve the air permeability of the coal seams. Background technique [0002] Methane is a flammable, explosive gas produced during the formation of coal. It is the main component of coal mine gas and the most harmful harmful gas in the process of coal mining. In order to prevent gas accumulation and explosion during coal mining, mines currently use ventilation and discharge methods to reduce the gas content in coal mine roadways. However, with the improvement of the degree of mechanization and the increase of coal output, simply adopting the ventilation method cannot effectively reduce the gas in the coal mine roadway. The gas in the coal seam must be drilled and pre-drained before mining in order to reduce the gas content in the coal seam and reduce the amount of gas gushing out d...
