Abstract
The invention relates to a dual-roller coal mining machine, in particular to an eight-meter large-mining-height coal mining machine. The eight-meter large-mining-height coal mining machine comprises a machine frame, a height adjustment arm, rollers, a rocker arm, a supporting arm, and a height adjustment oil cylinder, wherein one end of the rocker arm is hinged with the height adjustment arm; the rollers are fixed at the other end of the rocker arm; one end of the supporting arm is fixed on the rocker arm; the other end of the supporting arm is hinged with a piston rod of the height adjustment oil cylinder; and the cylinder body of the height adjustment oil cylinder is fixed or hinged with the height adjustment arm. By the eight-meter large-mining-height coal mining machine, a problem that the conventional dual-roller coal mining machine cannot realize full-seam mining for core seams higher than 6 meters is solved successfully. According to the eight-meter large-mining-height coal mining machine, the height adjustment oil cylinder, the rocker arm and the supporting arm are added on the basis of the original dual-roller coal mining machine structure, so that eight-meter mining height is realized by a small-roller, small-size and low-power coal mining machine; and moreover, the eight-meter large-mining-height coal mining machine is high in adaptability, advanced in performance and high in coal mining efficiency.
Description
Technical field
The present invention relates to double-ended shearer, be specially a kind of eight meters large mining-height coal mining machines.
Background technology
Existing double-ended shearer comprises by left socle and right support and is connected to form the frame 6 that inside has the frame chamber, electric control gear 8 and hydraulic means 9 are installed in the frame chamber of frame 6, two ends, frame bottom are equipped with the tractive unit 10 that contains roller, the two ends symmetry of frame is hinged with heightens arm 4, the other end of heightening arm 4 is fixed wtih cylinder 1, also comprise elevating ram 5, the cylinder body of elevating ram 5 is hinged on the frame 6, the piston rod of elevating ram 5 with heighten arm 4 middle parts and be connected, the hinged place of the cylinder body of elevating ram 5 and frame 6 heighten the hinged place of arm 4 and frame 6 below.During coal-winning machine work, the roller of tractive unit is positioned on the track of scratch board conveyor on the frame, the lifting of hydraulic means control elevating ram wherein one is heightened arm, by the height that arm is heightened cylinder roof of heightening of lifting, another cylinder is not heightened, and then tractive unit drive coal-winning machine moves to the direction of heightening cylinder, electric control gear simultaneously index drum rotates, the cylinder of heightening is just along the seam roof coal cutting, and another cylinder is along the seat earth coal cutting, and coal-winning machine is realized coal cutting.The diameter of cylinder of double-ended shearer is generally between 1 ~ 3 meter, the diameter of two cylinders and the maximum mining height that is this coal-winning machine, the maximum mining height of therefore existing coal-winning machine only has 6 meters, and thickness can not be realized once adopting entirely greater than 6 meters coal seam, and want to develop mining height greater than 6 meters coal-winning machine according to conventional thinking, just must increase diameter and the power of motor or the brachium that arm is heightened in increase of cylinder, certainly will cause like this machine volume huge, installed power is very large, frame for movement is unreasonable, and the brachium increase of heightening arm has increased potential safety hazard, and then gives the high seam in colliery efficient, safety, mechanical mining brings a lot of inconveniences.
Summary of the invention
The present invention provides a kind of eight meters large mining-height coal mining machines in order to solve the problem of existing double-ended shearer coal mining insufficient height.
The present invention adopts following technical scheme to realize: a kind of eight meters large mining-height coal mining machines, comprise frame, heighten arm, cylinder, also comprise rocking arm, support arm, adjust high cylinder; an end of rocking arm is hinged with the end of heightening arm; the other end of rocking arm is fixed wtih cylinder; an end of support arm is fixed on the rocking arm, and the other end of support arm and the piston rod of adjust high cylinder are hinged, and the cylinder body of adjust high cylinder is fixed or is hinged on and heightens on the arm.When heightening arm and given rise to maximum height, with heightened by lifting that arm is fixed or hinged adjust high cylinder lifts rocking arm by support arm, thereby cylinder is heightened the height (the highest can heighten eight meters) of roof, the cylinder of heightening is just along the seam roof coal cutting, another cylinder is along the seat earth coal cutting, and the interlude in coal seam then is caving by self gravitation.Eight meters large mining-height coal mining machines are by the height that stretches to adjust coal mining of two-stage oil cylinder, the highest coal mining highly can reach eight meters, and the diameter of cylinder does not increase, and the brachium of heightening arm does not increase yet, coal-winning machine is realized eight meters mining heights coal minings with less installed power, and safe and efficient.
Eight meters above-mentioned large mining-height coal mining machines, the diameter of cylinder is 2 meters, can guarantee that coal-winning machine is behind the coal that slices off roof and base plate, the coal of coal seam interlude can be caving by self gravitation, if diameter of cylinder is too little, the coal seam of interlude probably can not be caving, then need artificial treatment, mine for machinery and bring inconvenience, if the coal seam of the excessive then interlude of diameter of cylinder easily is caving, large but the installed power of coal-winning machine just becomes.
Eight meters above-mentioned large mining-height coal mining machines; frame is equipped with the gear device for coal on the top; the gear device for coal comprises spillplate and at least one oil cylinder wide with frame; one end of spillplate is hinged on the upper side in frame top; the side plate face of the piston rod of oil cylinder and spillplate (non-gear coal lateral plates) is hinged; the cylinder body of oil cylinder is hinged on the opposite side on the frame top; the gear device for coal can prevent that the coal cinder that drops from pounding the damage coal-winning machine; and the gradient of the spillplate in the gear device for coal regulates voluntarily according to the thickness in coal seam, can be effectively protected so that coal-winning machine is operated in the coal seam of different-thickness.
The present invention is directed to conventional double-ended shearer and can't realize the problem of full-seam mining in coal seam more than 6 meters, adjust high cylinder, rocking arm and support arm have been increased at original double-ended shearer architecture basics, so that doffer, small size, low power coal-winning machine have been realized eight meters mining heights, and strong adaptability of the present invention, advanced in performance, coal mining efficient is high, the problem of the existing twin-roll coal mining insufficient height of successful solution.
