Description
Technical field
The utility model relates to digging laneway support in a kind of underground coal mine and coal rock layer, particularly a kind of light-duty down-hole driving support.
Background technology
During coal mine underground tunneling roadway, after development machine falls to coalingging rock stratum, for ensureing construction safety, need to help to carry out temporary lining to back and two, because limiting by lane space, what generally adopt at present helps temporary lining technology to have three kinds to top board and two, and one is adopt π steel or round steel pipe as front spy temporary lining, two is adopt on development machine to add metal casing, and three is adopting the metallic support can taking a step to move forward to couple together as temporary lining.But above three kinds of modes all Shortcomings, the shortcoming of the first support pattern cannot realize quick supporting, supporting mechanism is passive stressed, top board cannot be given initiatively to support, and holding capacity is little, the second supporting is because occupying the space of driving during development machine supporting, continuous driving can not be realized, the third mode step type metallic support, support causes repeatedly disturbance because taking a step repeatedly to rise to unload when moving forward to top board, be unfavorable for Roof Control, in addition the second development machine adds metal casing not accomplish to adjust in time according to span length change with the third metallic support, cause cannot realizing carrying out supporting to roadway full-fracture-surfacanchoring-rod at any time.Wherein second and third kind of support pattern all can not be accomplished to realize continuous driving, must then carry out installing anchor pole after each circulation temporary lining is complete and make permanent support, and two kinds of support patterns all cannot carry out active support to roadway's sides, the move mode of above two kinds of supportings is step type or pull-type.
Summary of the invention
The purpose of this utility model is to provide a kind of light-duty down-hole driving support, the shortcoming of above-mentioned three kinds of support patterns can be overcome, move mode is become aerial mobile, can realize helping to carry out active support to back and two fast, disturbance is not repeatedly formed to top board, realize tunneling continuously fast of tunnel.
For achieving the above object, the scheme that the utility model is taked is: a kind of light-duty down-hole driving support, comprise back timber and hydraulic vertical prop, it is characterized in that: described back timber slidably connects left extensible canopy and right extensible canopy, described left extensible canopy, right extensible canopy horizontally slip along back timber respectively by the left telescopic oil cylinder be fixedly connected with back timber, the flexible of right telescopic oil cylinder, and the bottom of left extensible canopy, right extensible canopy is all fixedly connected with described hydraulic vertical prop; Left face guard and right face guard is also hinged with respectively in the bottom surface of left extensible canopy and right extensible canopy, described left face guard, right face guard rotate along pin joint respectively by left face guard oil cylinder, the flexible of right face guard oil cylinder, and the cylinder body of described left face guard oil cylinder, right face guard oil cylinder is articulated with the bottom surface of left extensible canopy, right extensible canopy respectively.
As preferably, be also fixedly installed forestope at the leading flank of described back timber, to accomplish advance support better, the angle of forestope and horizontal plane is adjustable.
As preferably, also comprise the connection frame chain being articulated with described back timber trailing flank, on the one hand, adjacent support can prevent support tilt after using connection frame chain to connect, and on the other hand, the length of connection frame chain can be utilized to judge the spacing of adjacent stent, ensure that support is evenly arranged.
As preferably, described hydraulic vertical prop is single telescopic, and its stroke is 700mm-900mm, can meet tunnel changes of section larger time instructions for use.
As preferably, described left telescopic oil cylinder and right telescopic oil cylinder are common double effect differential cylinder, can reduce its retraction time, improve drivage efficiency.
The utility model beneficial effect: extensible canopy, a face guard and hydraulic leg all adopt scalable design, ensureing under the prerequisite to tunnel active support, achieve the aerial mobile fast of driving frame, and disturbance repeatedly can not be formed to top board, can be formed and cover full face supporting, solve the problem then must carrying out permanent support in tunnel after temporary lining simultaneously.

Detailed description of the invention
A light-duty down-hole driving support, comprises back timber 6, hydraulic vertical prop 1 as shown in Figure 1, left extensible canopy 4, right extensible canopy 8, left telescopic oil cylinder 5, right telescopic oil cylinder 7, left face guard 2, right face guard 10, left face guard oil cylinder 3, right face guard oil cylinder 9, back timber 6 is formed by Plate Welding, the centre position of bottom surface is provided with four locating holes, left extensible canopy 4 and right extensible canopy 8 are all slidably connected with back timber 6, left telescopic oil cylinder 5 and right telescopic oil cylinder 7 are common double effect differential cylinder, its cylinder body is fixed on back timber 6, piston external part is fixedly connected with right extensible canopy 8 with left extensible canopy 4 respectively, piston stretches out direction respectively towards the two ends of back timber 6, hydraulic vertical prop 1 is all fixedly connected with in the bottom of left extensible canopy 4 and right extensible canopy 8, hydraulic vertical prop 1 is single telescopic structure, stroke is 700mm-900mm, its external part and extensible canopy hinged, left face guard 2 and right face guard 10 are articulated with the end of left extensible canopy 4 and right extensible canopy 8 bottom surface respectively, the cylinder body of left face guard oil cylinder 3 and right face guard oil cylinder 9 is articulated with the bottom surface of left extensible canopy 4 and right extensible canopy 8 respectively, and being positioned at the inner side of left face guard 2, right face guard 10 and left extensible canopy 4, right extensible canopy 8 pin joint, the piston external part of left face guard oil cylinder 3 and right face guard oil cylinder 9 is hinged with left face guard 2, right face guard 10 respectively.
When driving support described in the utility model uses as first frame, the leading flank of back timber 6 is provided with forestope 12, forestope 12 is adjustable with horizontal plane angle, and the trailing flank of back timber 6 arranges connection frame chain 11, and connection frame chain 11 adopts loop chain form, is fixedly connected with back timber 6; When described support is not as first frame, then do not need forestope 12, connection frame chain 11 only need be set, support adjacent for front and back be connected successively, prevents from toppling over, determine the spacing between support by the length of connection frame chain 11 simultaneously.
