The end of one of them half section of steelframe, the outer diameter of guide cylinder is identical as the internal diameter of pilot hole, or is slightly less than the interior of pilot hole
Diameter, guiding role when realizing that driving device driving is flexible by the cooperation of pilot hole and guide cylinder, enables two and half sections of steelframes
Enough relative telescopics along its length.
In aforementioned supporting arch, the vertical steelframe bottom is provided with wheel, and guiding arch is laid with preferably on the ground of tunnel
The track of frame moving direction.
The beneficial effects of the present invention are：
(1) steelframe is scalable, and it is removable when wall contracting that the driving device on vertical steelframe drives vertical steelframe elongation to be close to
It unloads decomposition or carries out holder adjustment；Top plate and two can be made to help to be obtained for good supporting in this way.
(2) arch detachably recycles afterwards, reduces support cost.
(3) simple in structure, install convenient, the stress that the arch quantity of installation can be helped according to roof rock stress and two is true
It is fixed；
(4) device manipulation is convenient, and driving device built-in structure ensures that device is protected by steelframe main body, is hardly damaged,
It is not easily accessible sundries.

Specific implementation mode
Below in conjunction with attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that institute
The embodiment of description is only a part of the embodiment of the present invention, instead of all the embodiments.
With reference to attached drawing 1-4, the present embodiment provides a kind of internally-arranged type Telescopic movable supporting arch, including retractable structure
Steelframe 1, the steelframe 1 include that two vertical steelframes 101 being vertically arranged and both ends connect with two 101 upper ends of vertical steelframe respectively
The arc top steelframe 102 of the arc connect, two vertical steelframes 101 are telescopic structure, and two vertical steelframes 101 are built-in with drive
The driving device 2 that vertical steelframe 101 vertically stretches is moved, multiple through-holes are offered on the side wall that steelframe 1 is contacted with wall
103；The driving device 2 is electric pushrod, and each vertical steelframe 101 is docked by two and half sections of steelframes, 2 edge of driving device
It is vertically fixed on the end of one of them half section of steelframe, the end of another half section of steelframe on the other side, which vertically offers, leads
To hole 104, the driving device 2 extends in pilot hole 104, and the other end of driving device 2 is fixed on the bottom of pilot hole 104
(modes such as welding can be used in fixed form), to realize the docking of two and half sections of steelframes, to form the vertical steelframe
101；The outside of the driving device 2 is also arranged with guide cylinder 105, the bottom of guide cylinder 105 also be secured to it is described one of them
The outer diameter of the end of half section of steelframe, guide cylinder 105 is identical as the internal diameter of pilot hole 104, or is slightly less than the internal diameter of pilot hole 104,
Guiding role when realizing that the driving of driving device 2 is flexible by the cooperation of pilot hole 104 and guide cylinder 105, makes two and half sections of steel
Frame being capable of relative telescopic along its length；101 bottom of vertical steelframe is provided with wheel 3, is preferably laid on the ground of tunnel
Guide the track of arch moving direction.
When that need to use multiple arches, two adjacent arches can be connected with removably.
The step of carrying out supporting using arch is as follows：
The first step：Each component of arch is transported to heading end by the transporting equipment of underground, it, will after laying track
Steelframe assembles, and is seated on track.
Second step：Arch is moved under the tunnel newly tunneled by development machine.
Third walks：The position of wheel 3 is fixed, if driving device 2 uses hydraulic pump, the first liquid on vertical steelframe 101
Liquid is added in press pump, increases the support pressure of hydraulic pump, keeps vertical steelframe 101 elongated laterally under the driving of hydraulic pump；
Liquid is added in the hydraulic pump on arc top steelframe 102 again, increases its pressure, makes to stretch under the driving of 102 hydraulic pump of arc top steelframe
It is long；Until 101 outside side wall of vertical steelframe is adjacent to wall, if using electric pushrod, it is not necessary that liquid is added, it is only necessary to control
Electric pushrod extends until 101 outside side wall of vertical steelframe is adjacent to wall.
4th step：By through-hole 103 on steelframe and gap, to tunnel around drilling, then squeeze into anchor pole and reinforced.
5th step：For mobile arch to the new position of next driving, the wall to squeezing into anchor pole adds anchor net or whitewashing etc.
Second consolidation.
