Description
Technical field
The utility model relates to the gib fields of mine working, traffic and water conservancy tunnel, and especially one kind is in tunnel
Used in tunnelling shield support.
Background technique
Currently, gib form used by coal mine roadway driving face has a column supporting, hydraulic prop to match
The forms such as metal hinge top beam supporting and falsework of conjunction.Wherein, column supporting and hydraulic prop complexed metal hinged roof are put
Beam supporting requires personnel and enters the ability operation of the area Kong Ding, has sizable risk, and personnel labor intensity is big, time-consuming
It is long, it is complicated for operation；Falsework is mainly automatic moving type falsework, move mode mainly have it is sliding and plug-type, but existing
In the actual production of field, automatic moving type falsework is not widely used as fully mechanized mining supporter in coal mine also, there are many technical problems,
Such as the complicated close gap between fully-mechanized digging machine of supporting structure, back out-of-flatness and the safe drill operation under bracket shielding
Deng.Wherein comparing outstanding problem is, most of automatic moving type falseworks are generally in view of set cap is not that a rigidity is whole
Component can only be supported in the several points of lowest part when either top plate is not complete plane for back out-of-flatness, cause to push up
Frame load distribution is uneven, it is easy to cause bracket to destroy, cause part or large area roof fall accident.In order to solve set cap
With both backs support issues, a kind of existing support shield type staggeredly slides temporary shoring bracket, sets on its top beam
Have at least two pairs of jack, local top plate realized and is supported, but the set cap is formed with multiple groups crossbeam, crossbeam and crossbeam it
Between spacing it is larger, if top plate occur part fall cash or roof fall, there are some potential safety problemss for operation under the bracket by drilling personnel；
There are also another to tunnel flexible top beam falsework, and flexible top beam is made of stringer and flexible-belt two parts, and stringer is erected at
Above trapezoid support, flexible-belt is made of glass reinforced plastic, thick tape and plasticity, but flexible-belt and back support repeatedly and be easy to break
Bad, maintenance is complicated, and spacing is larger between crossbeam and crossbeam, stringer and stringer, is also unsatisfactory for the safety work under bracket and wants
It asks.Therefore, how to guarantee tunnelling shield support stability, improve drilling efficiency and at lane speed, guarantee bore operation people
Member's safety is problem to be solved in the utility model.
The information disclosed in the background technology section is intended only to deepen the reason to the general background technology of the utility model
Solution, and it is known to those skilled in the art existing to be not construed as recognizing or imply that the information is constituted in any form

Spacing is greater than the width of development machine 200.Bogey (the figure for carrying fixed shield support 1 is provided on development machine 200
In be not shown), bogey can be there are many form, such as magnetic-type, caliper brake, the table top with guide cone or pin,
As long as shield support 1 can be fixed on development machine 200, clamping device is the prior art, and this will not be repeated here.
When carrying out gib operation, shield support is moved to 100 supporting region of tunnel, clamping device by development machine 200
Shield support is discharged, two-way Ding Shen mechanism 2 extends downwardly lower piston roofbolt 9, and lower piston roofbolt 9 contacts 102 (of roadway floor
Face) after continue to stretch out, will shielding plate-girder 1 be raised to setting height, subsequent upper piston roofbolt 8 is extend out to be connect with back 101
Touching, shield support supporting are completed.
Certainly, the flexible sequence of two-way Ding Shen mechanism 2 can have other kinds of schemes to realize the stabilization of shielding plate-girder 1
Lifting, therefore no longer repeated herein.
Embodiment 2
It is as shown in figures 6 a and 6b second of embodiment of the utility model tunnelling shield support, the present embodiment
It is essentially identical with the structure of embodiment 1, the difference is that, upper hydraulic cylinder 6 and lower hydraulic cylinder 7 in two-way Ding Shen mechanism 2 are
It is staggered in plane, keeps hydraulic cylinder 6 parallel with the axis of lower hydraulic cylinder 7.Specifically, load crossbeam 10, position are set
Lower hydraulic cylinder 7 in the same side is fixed on 10 downside of load crossbeam, and upper hydraulic cylinder 6 is fixed on the upside of load crossbeam 10.It needs to protect
Resultant moment on card shielding plate-girder 1 is zero.
Embodiment 3
The present embodiment and the structure type of embodiment 1 are essentially identical, the difference is that, driving is provided on shield support
Its moving drive mechanism moved along 100 extending direction of tunnel.Make shield support in tunnel 100 by moving drive mechanism
It is moved out development machine 200, can independently be carried out.Moving drive mechanism can be specifically that guide rail is arranged on roadway floor,
Push cylinder is set on shield support, and the movable end of push cylinder is matched with guide rail, can be moved along guide rail, movable end setting
There is locking device, locked movable end and guide rail by locking device, realizes bracket on roadway floor by push cylinder
It is mobile.The concrete form of moving drive mechanism is not limited to this, any mechanism that shield support can be driven to move in tunnel
?.
The sequencing of above embodiments is not only for ease of description, represent the advantages or disadvantages of the embodiments.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
