The two guide rail drill carriages in a kind of colliery
Technical field
The present invention relates to the drill carriage that a kind of colliery pump drainage gas is used, the two guide rail drill carriages in specifically a kind of colliery.
Background technology
In order to eliminate the permeable and gas accident hidden danger in colliery, ensure the safety of Coal Production, prevent that because of major accident permeable and that gas is outstanding, country is decided to be rigid measure with the colliery outstanding work of anti-permeable anti-gas.Gas drainage under suction and the remote water of visiting are the essential measures of administering coal mine gas and water leak accident.The drill carriage that uses is owing to complex structure, poor stability, fault rate height at present, bore angle is adjusted underaction, drilling efficiency is low, and can't adjust the distance of borer rail and getting working face under the situation of mobile body not, can not satisfy the demand of down-hole drilling operation.
Summary of the invention
Technical problem to be solved by this invention provides the high colliery of a kind of novel structure, drilling efficiency with two guide rail drill carriages, can adjust the distance of borer rail and getting working face under the situation of mobile body not.
The present invention is the deficiency that solves the problems of the technologies described above, the technical scheme that is adopted is: the two guide rail drill carriages in a kind of colliery, comprise running gear and frame, link in running gear and frame is provided with rotary disk, frame can 360 ° of rotations by rotary disk, on frame, be arranged with two borer rails, borer rail is hung on travelling carriage, travelling carriage is arranged on the support arm, one end of support arm is connected with hoist cylinder, the other end is connected with lifting support, link at support arm and lifting support also is provided with the angle adjustment oil cylinder, and lifting support is connected with frame respectively with movable branching rod by the active pull rod that is arranged on the end, and borer rail is followed travelling carriage front and back on support arm and slided, can carry out 45 adjustment up and down, also be arranged with top plate stanchions at the two ends of frame.
Also be provided with the telescopic oil cylinder that is connected with travelling carriage on the described support arm.
Described frame, its two ends are respectively equipped with bottom plate stanchions.
Described borer rail is provided with the rig seat and advances oil cylinder in its rail groove.
Described rig seat is provided with rig, and rig is provided with drilling rod.
The invention has the beneficial effects as follows: the drill carriage novel structure, the flexible drive telescopic arm by hoist cylinder makes its rising or reduction, to adjust the height of borer rail.The flexible angle that can adjust lifting support and support arm of angle adjustment oil cylinder, thereby the angle of adjustment borer rail.Frame can rotate freely on running gear by rotary disk, thereby adjusts the direction of creeping into.Can adjust the position and the angle of boring flexibly by above setting.In the telescopic arm both sides borer rail is set respectively, two drilling rods are holed simultaneously, can increase work efficiency greatly.As back support, front end makes its structure more stable by the unique way that hoist cylinder supports, and greatly reduces maintenance rate by the different movable branching rod of length and active pull rod in employing.Borer rail stretches out with the travelling carriage on the telescopic arm or regains, and adjusts the distance of borer rail and getting working face as required flexibly, avoids frequently adjusting the body position, has saved the working time greatly.

The specific embodiment
As shown in the figure, a kind of colliery comprises running gear 1, frame 2, borer rail 5, rig 15 and drilling rod 16 with two guide rail drill carriages.Running gear 1 can use cterpillar drive.Be provided with rotary disk 3 on running gear 1, frame 2 is arranged on the rotary disk 3, can carry out 360 ° of rotations.Rig 15 is arranged on the rig seat 4 in the rail groove of borer rail 5, and be connected with a end of propelling oil cylinder 14 in the borer rail 5, move forward and backward along borer rail 5 by the flexible drive rig 15 that advances oil cylinder 14, creep into, continue to creep into after returning the continued access drilling rod then so that drive drilling rod 16.Be provided with drilling rod 16 on rig 15, drilling rod 16 centers are provided with through hole, can ventilate or water flowing, are used for the row's powder or the cooling drill bit of boring procedure.Be arranged with two borer rails 5 on frame 2, borer rail 5 is hung on travelling carriage 11, and two cover rigs can be installed, and boring is increased work efficiency greatly simultaneously.Travelling carriage 11 is arranged on the support arm 12, and an end of support arm 12 is connected with hoist cylinder 7, and the other end is connected with lifting support 6.Link at support arm 12 and lifting support 6 also is provided with angle adjustment oil cylinder 10, thereby can adjust the angle that support arm 12 and the angle of lifting support 6 are adjusted borer rail 5 by angle adjustment oil cylinder 10, makes it can carry out 45 adjustment up and down.Lifting support 6 is connected with frame 2 respectively with movable branching rod 8 by the active pull rod 9 that is arranged on the end, and the length of movable branching rod 8 is 1/2~2/3 of active pull rod 9 length.The two ends of movable branching rod 8 and active pull rod 9 are rotationally connected with lifting support 6 and frame 2 respectively, so that can adjust support angle flexibly when lifting support 6 is adjusted height.Hoist cylinder 7 is arranged on the frame 2, can adjust the height that support arm 12 lifts by hoist cylinder 7.On support arm 12, also be provided with the telescopic oil cylinder 13 that is connected with travelling carriage 11, the telescopic oil cylinder 13 flexible borer rails 5 that can drive are followed travelling carriage 11 front and back slip on support arm 12, thereby adjust the length that borer rail 5 stretches out, to adapt to the getting working face of different distance.Described frame two ends are arranged with top plate stanchions 17 and bottom plate stanchions 18.Top plate stanchions 17 is a support column, is provided with hydraulic cylinder at its top, and the hydraulic cylinder bottom is supported by baffle plate.Bottom plate stanchions 18 can be selected hydraulic cylinder for use, and hydraulic cylinder is fixed on the frame 2, and its flexible end is provided with downwards, can support ground when elongation.Top plate stanchions 17 and bottom plate stanchions 18 are respectively applied for top board and the base plate that supports coal mine roadway, and the balance of drill carriage is stable during with the maintenance bore operation.Described top plate stanchions 17 can respectively be provided with one at the two ends of frame 2.Described bottom plate stanchions 18 can respectively be provided with two at the two ends of frame 2, promptly four foundation plate pillars 18 are separately positioned on four angles of frame 2.
