Description
Technical field
The present invention relates to the downhole coal mine temporary supporting device of driving working face, especially for the new temporary supporting device that discloses empty top zone after the driving face explosion.
Technical background
At present, there are many coal mine roadway drivings to adopt blasting procedure.Driving face adopts hanging-ring type π shaped steel forestope to cooperate the lumps of wood to make temporary lining technique.This temporary lining technique falls behind, and the operation holding time is long, technique is loaded down with trivial details, and personnel still will enter the empty top zone operation, have caused the temporary lining safety factor low, and worker's labour intensity is large; Supporting intensity is low, is unfavorable for safety in production, jeopardizes the inherently safe of constructor under the temporary lining, seriously restricts the raising of driving speed.
Summary of the invention
In order to overcome the deficiency of existing temporary lining technique, the invention provides the leading falsework of a kind of all-hydraulic automatic moving type.This falsework not only can satisfy the requirement of empty top zone supporting intensity, and can certainly move and advance, and is mobile convenient, and supporting is convenient.
Technical scheme is, the leading falsework of a kind of all-hydraulic automatic moving type, it comprises base, be hinged with respectively the column oil cylinder on the four corners position of base, the column oil cylinder comprises two front pillar oil cylinders and two rear pillar oil cylinders, be hinged with on front pillar oil cylinder and the rear pillar oil cylinder and connect head piece, the front end that connects head piece is hinged with front spy arm, front spy arm and connect and be hinged with telescopic oil cylinder between the head piece, be hinged with the diagonal brace oil cylinder between the rear portion of front pillar oil cylinder and base, the front portion of base is equipped with from moving oil cylinder, and the operating valve group is installed on the back platform of base, controls the action of each oil cylinder by the operating valve group.
For the support that crumbles of the spoil after preventing from blowing out, be provided with baffle plate in the front of front pillar oil cylinder.
The operating principle of the leading falsework of this all-hydraulic automatic moving type is, provides power by hydraulic power unit, promotes valve group valve rod, makes hydraulic oil enter each oil cylinder by shunting, afflux, reversal valve.Enter the column oil cylinder support bracket that can raise and hold top board; Enter the diagonal brace oil cylinder and adjust inclination angle, support bracket front and back, to adapt to the inclination angle, tunnel; Entering telescopic oil cylinder makes and visits arm before the support and stretch out and withstand the empty top of work plane; Enter from moving oil cylinder, the pulling support is forward from moving.
The using method of the leading falsework of this all-hydraulic automatic moving type is, will certainly move oil cylinder before blowing out and stretch out, and is fixed in the bottom supporting of tunnel, operates simultaneously the column oil cylinder and allows and connect head piece and leave top board, will certainly move the oil cylinder pulling support of retracting and move to and meet head on; The operation telescopic oil cylinder bounce back front spy arm, and operates the column oil cylinder and allow and connect head piece and hold top board; The rear operation telescopic oil cylinder of blowing out is visited before with front spy arm, places steel band and supporting mesh at front spy arm simultaneously, until front spy knee-joint top, thereby the empty top temporary lining after will blowing out goes out the perforating charging work of cash and next circulation under temporary lining.
Good effect of the present invention is, it is short to blow out the rear temporary lining time, support can be visited and realize zero empty topization to meeting head on, all process steps all is to carry out under effective support, supporting intensity is large, safe and reliable, reaches " pick three anchors " or " the many anchors of a pick " pattern, and " pick one anchor " that break traditions falls behind support process, promote the reasonable parallel operations of inter process, improve drilling depth efficient.
Description of drawings
Further specify the embodiment of the invention below in conjunction with accompanying drawing.
Fig. 1 is the front view of the embodiment of the invention.
Marginal data, 1-operating valve group is visited arm before the 2-, 3-rear pillar oil cylinder, the 4-telescopic oil cylinder, 5-diagonal brace oil cylinder, 6-connects head piece, and 7-is from moving oil cylinder, 8-base, 9-baffle plate, 10-front pillar oil cylinder.
The specific embodiment
As shown in Figure 1, the leading falsework of a kind of all-hydraulic automatic moving type, it comprises base 8, be hinged with respectively the column oil cylinder on the four corners position of base, the column oil cylinder comprises two front pillar oil cylinders 10 and two rear pillar oil cylinders 3, be hinged with on front pillar oil cylinder 10 and the rear pillar oil cylinder 3 and connect head piece 6, the front end that connects head piece 6 is hinged with front spy arm 2, front spy arm 2 and connect and be hinged with telescopic oil cylinder 4 between the head piece 6, be hinged with diagonal brace oil cylinder 5 between the rear portion of front pillar oil cylinder 10 and base 8, the front portion of base 8 is equipped with from moving oil cylinder 7, and operating valve group 1 is installed on the back platform of base 8, by the action of operating valve group 1 each oil cylinder of control.For the support that crumbles of the spoil after preventing from blowing out, be provided with baffle plate 9 in the front of front pillar oil cylinder 10.
Using method of the present invention is, to certainly move oil cylinder 7 before blowing out and stretch out, stretched head is fixed in the supporting of tunnel bottom, operates simultaneously front pillar oil cylinder 10 and two rear pillar oil cylinders 3 and allows and connect head piece 6 and descend, make to connect head piece 6 and leave top board, will certainly move the oil cylinder 7 pulling supports of retracting and move to and meet head on; Operation telescopic oil cylinder 4 is front spy arm 2 retractions, and operation front pillar oil cylinder 10 and two rear pillar oil cylinders 3 rise, and allows connect head piece 6 and hold top board; Blow out rear operation telescopic oil cylinder 4 with front spy arm 2 front spies, place steel band and supporting mesh at front spy arm 2 simultaneously, until front spy arm 2 connects the top, thereby the empty top temporary lining after will blowing out goes out the perforating charging work of cash and next circulation under temporary lining.
