[ detailed description ] embodiments
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a mining system of demolising hydraulic support in pit, as shown in figure 1, include:
the first fixed pulley 2 and the third fixed pulley 4 are fixed on the upper part of any one hydraulic support at two sides of the pre-dismantling support 1, the first fixed pulley 2 and the third fixed pulley 4 are positioned on the same support beside the pre-dismantling support 1, and the pre-dismantling support 1 is positioned at an underground hole cutting position.
A second fixed pulley 3 fixed at the middle part of the pre-dismantling bracket 1,
the fourth fixed pulley 5 is fixed at the bottom of the pre-dismantling support 1; the first fixed pulley 2, the second fixed pulley 3, the third fixed pulley 4 and the fourth fixed pulley 5 are all 10-ton pulleys.
The winch 6 is positioned at the junction of the underground cutting hole and the air inlet lane 8; and a hook head lock of the winch rope 7 is communicated with the winch rope 7 to penetrate through the first fixed pulley 2, the third fixed pulley 4, the second fixed pulley 3 and the fourth fixed pulley 5 and is hooked at the upper part of the pre-dismantling support 1, and the hook head lock is positioned at the middle position of the first fixed pulley 2 and the third fixed pulley 4. The winch rope 7 sequentially passes through the first fixed pulley 2, the second fixed pulley 3, the third fixed pulley 4 and the fourth fixed pulley 5.
The utility model discloses hydraulic support demolishs the method that adopts whole demolishs, and the winch 6 cooperation direction wheelset of promptly drags the support whole body outward, at first carries out perpendicularly to promoting hydraulic support, then turns to towards 6 directions of winch gradually, makes the parallel ground of winch 6 at last to the accent is to 90 degrees. The utility model discloses taken 4 fixed pulleys, each pulley all used quick-operation joint with the leg joint, did not use the split ring, with 7 atress dispersions of winch rope on each pulley, this has not only reduced the single pulley and has been broken by the drawing, the part collapses personal safety, wire rope and damages, has not only ensured the safety of person, equipment, also can withdraw fast under the broken withdrawal condition of roof.
The utility model discloses an install second fixed pulley 3 and fourth fixed pulley 5 and demolish support 1 in advance, under the pulling of winch 6, demolish support 1 in advance and constantly remove, and these two fixed pulleys are equivalent to two movable pulleys, and then play the effect of province to mutually support with first fixed pulley 2 and third fixed pulley 4 and can reach laborsaving, can change the purpose of power direction again.
Example 1
As shown in fig. 2 and 3, a first fixed pulley 2 is arranged at a point A, a second fixed pulley 3 is arranged at a point B, namely two pulleys are fixed on a forepoling bar of a bracket 12 beside a pre-dismantling bracket 1, a third fixed pulley 4 is arranged at a point C, namely fixed on a jack fixing rod of the pre-dismantling bracket 1, and a fourth fixed pulley 5 is fixed at a four-link position of the pre-dismantling bracket 1, namely a point D. As shown in figure 1, a winch 6 is positioned at an air inlet lane 8, a hydraulic support presses the air inlet lane 8 to an air return lane 9 to be arranged, after the hydraulic support is withdrawn, rock mountain of the lane falls and is filled through the lane to become a withdrawn area 10, the position of the hydraulic support to be dismantled is an area 11 to be withdrawn, two pulleys A and C are fixed on a front canopy of the same support beside a pre-dismantling support 1, a pulley B is fixed on a fixed rod of a jack of the pre-dismantling support 1, a pulley D is fixed on a four-link of the pre-dismantling support 1, and a hook head of a winch rope 7 is hooked at a front canopy E of the same support beside the pre-dismantling support 1. And starting the winch 6, stopping traction when the pre-dismantling support 1 reaches the position F, dismantling the pulley block, directly hanging the hook head rope on the pre-dismantling support 1, pulling out the pre-dismantling support 1 along the dismantling roadway until the pre-dismantling support 1 is transported to the rail roadway, loaded and recycled.
Because the support withdraws more difficultly under the stress action of roof and country rock, the support dead weight is greater than 20 tons in addition to the country rock effort, and general design winch 6 is 20 tons, in 3301, 1305 combine to adopt the working face to tear open, 120 too hydraulic support altogether, through the utility model discloses it only needs about 13 days to demolish whole working face, and if adopt prior art's the case, needs about 30 days.
The utility model provides a back to back the damage of support wire rope and serious, 6 big problems of load of winch have both practiced thrift the material for the speed of the back of support again.
