Abstract
The invention discloses an E-shaped pushing and grinding rack device for dismounting a coal mine hydraulic bracket. The E-shaped pushing and grinding rack device comprises an E-shaped pushing framework, wherein the E-shaped pushing framework consists of a beam and three longitudinal beams; the three longitudinal beams are respectively positioned at the two ends and the middle of the inner side end surface of a beam; the longitudinal beams at the two ends are each provided with a framework clamping-and-inclining-resistant mechanism; two cross head connecting holes are formed in the inner side end surface of the beam; two auxiliary connecting heads are arranged on the outer side end surface of the beam; the two cross head connecting holes are respectively positioned every two of the three longitudinal beams; and the inner end of a grinding rack is connected with the cross head connecting holes, and the rear end of the grinding rack is connected with an insertion pin. The E-shaped pushing and grinding rack device realizes the function of shielding bracket linear self-movement and the hydraulic bracket grinding rack, avoids the original operation ways such as alternative shed erecting and shed returning, monomer column and n-shaped beam carrying and the like, guarantees safe and efficient withdrawing of a fully mechanized coal mining face, is time-saving and labor-saving, and is more remarkable in effect during large-inclination-angle withdrawing.
Description
technical field:
The present invention relates to a kind of coal mine fully-mechanized mining working hydraulic support withdrawn in operation and remove the passing of E type and the work of mill frame, particularly relate to a kind of coal mine hydraulic supporting dismounting E type and pass and mill rack device.
background technology:
Withdraw in operation at coal mine fully-mechanized mining working, it is a common important content that coal mine hydraulic supporting is removed, it directly has influence on fully-mechanized mining working and withdraws efficiency and safety factor, and particularly when conventional hydraulic support removing, double shield is passed needs winch to coordinate tractive, if when top board is comparatively broken, very easily make shield support in passage kill, pass cause difficulty to shield support, hydraulic support withdrawing mill frame speed is slower in addition, serious restriction withdraws progress, and jeopardizes personal safety.
summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, be easy to manipulation, the high and coal mine hydraulic supporting that labour intensity is low of operating efficiency removes E type and passes and mill rack device.
Technical scheme of the present invention is:
A kind of coal mine hydraulic supporting is removed E type and is passed and mill rack device, containing E type passing frame, described E type passing frame is made up of a crossbeam and three longerons, three described longerons lay respectively at two ends and the centre of described cross rail inner end face, the described longeron at two ends is arranged respectively an anti-framework Jia Xie mechanism, described anti-framework Jia Xie mechanism is by pressure cylinder, connector, chain link and latch are connected in sequence, the described longeron at described pressure cylinder and two ends is hinged, described cross rail inner end face is arranged two cross head connecting holes, its end face outside is provided with two auxiliary connectors, two described cross head connecting holes lay respectively at three described longerons between any two, the inner of mill frame is connected with described cross head connecting hole, its rear end is connected with described latch.
The two ends of described cross rail outer end face are respectively arranged with reinforcing baffle plate, and the two sides of the inner surface of the longeron at two ends and the longeron of centre are provided with wear-resisting clamping plate respectively.
Be provided with telescopic hydraulic cylinder and chain link between described mill frame and cross connecting hole, described mill frame is two, lays respectively between the longeron at two ends and the longeron of centre; Described pressure cylinder is hydraulic cylinder or pneumatic cylinder, or is jack.
The invention has the beneficial effects as follows:
1, present invention achieves shield support straight line and grind holder function from moving with hydraulic support, when having stopped conventional hydraulic support removing, frame canopy need be replaced and return canopy and original operating type such as carrying monomer column and π type beam etc., ensure that fully-mechanized mining working is safe and efficient to withdraw, laborsavingly save time, when high inclination-angle withdraws, effect will be more remarkable.
2, present invention, avoiding a dead lift work that one withdraws " 2200 monomer columns, 600 π type beams " in the duration, reduce worker's labour intensity, improve operating environment, improve dismounting efficiency, reach 18/day, dismountable support, shorten 3 ~ 5 days/duration, decrease 64 people/duration, economic benefit is obvious.
3, the present invention is connected with shield support by the cross head of E type passing frame, and two shield supports are cooperatively interacted, and becomes from moving by passing, realization " intersect, take a step " from shifting function; Another installation two jack, make it be connected with shield support base by chain, cause E type passing frame to press from both sides oblique phenomenon when avoiding shield support to move forward.
4, the present invention is connected with telescopic jack and chain by E type passing frame front end cross head, makes it coordinate winch auxiliary dilatory, realizes removing hydraulic support mill holder function.
5, the present invention is reasonable in design, operating efficiency is high and labour intensity is low, and it is applied widely, and safety benefit is remarkable, has very strong promotional value.
