Description
Technical field
The present invention relates to underground coal mine supporting field more particularly to a kind of balanced type Telescopic movable supporting arches up and down.
Background technology
Heading end roof accident threatens always the life safety of personnel in the pit, and frequent occurrence.Roof accident refers to
During underground coal mining, because of the accidents such as casualties, equipment damage, production suspension caused by top plate accident inbreak.In reality
Before row fully mechanized mining, roof accident occupies very high ratio, up to 75% in coal mining accident.With hydraulic support use and it is right
The research of roof accident and prevention technique deeply and gradual perfection, the ratio shared by roof accident is declined, but still is
One of major casualty of coal production, as most dangerous one of place, roof accident happens occasionally heading end.With adopting deep increasing
Add, the prevention of heading end roof accident becomes more important.The pillar that majority stope working surface of coal mines uses at present still compares
Fall behind, prop drawing is substantially manual work, is easy for burying the hidden danger of roof fall accident in this way.
Invention content
It is an object of the invention to：A kind of balanced type Telescopic movable supporting arch up and down is proposed, effectively to ensure

The driving device for driving vertical steelframe vertically to stretch is both provided with to side wall；It is provided with drive arc on the arc crown frame
The flexible driving device of crown frame；Offer multiple through-holes on the side wall that steelframe is contacted with wall, two vertical steelframes it is interior
Side is vertically and fixedly provided with lateral connection frame, and the bottom of lateral connection frame is provided with universal wheel, between the lateral connection frame of both sides
It is fixed with driving device, driving device is transversely arranged perpendicular to vertical steel frame, and the both ends of the driving device are individually fixed in
On the lateral connection frame of both sides.
Preferably, the driving device is hydraulic pump or telescopic cylinder.
Preferably, the vertical steelframe bottom is provided with wheel, and guiding arch movement side is laid with preferably on the ground of tunnel
To track.
The beneficial effects of the present invention are：
(1) steelframe is scalable, and the driving device drive arc crown frame on arc crown frame is close to wall, cooperation two when extending
Driving device between a vertical steelframe, when driving device drive arc crown frame transverse extension, can make two vertical steelframes be close to lane
Road side wall, when shortening, can reduce steelframe overall width and be conveniently adjusted and move holder；Driving device driving on vertical steelframe is perpendicular
Holder adjustment is detachably decomposed or carries out when being close to wall contracting to steelframe elongation；Can make in this way top plate and two help all to obtain it is fabulous
Supporting.
(2) arch detachably recycles afterwards, reduces support cost.
(3) simple in structure, install convenient, the stress that the steelframe quantity of installation can be helped according to roof rock stress and two is true
It is fixed.
Description of the drawings
Fig. 1 is a kind of balanced type Telescopic movable supporting arch front view up and down of the present invention.
Fig. 2 is a kind of balanced type Telescopic movable supporting arch side view up and down of the present invention.
In figure：1- steelframes, the vertical steelframes of 101-, 102- arc crown framves, 2- driving devices, 3- wheels.
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 Fig. 1 and 2, the present embodiment provides a kind of balanced type Telescopic movable supporting arch up and down, including it is scalable
The steelframe 1 of structure, the steelframe 1 include two vertical steelframes 101 being vertically arranged and are fixed with two 101 upper ends of vertical steelframe
The arc crown frame 102 of connection；Described two 101 opposing sidewalls of vertical steelframe, which are both provided with, drives vertical steelframe 101 along vertical side
To flexible driving device 2；The flexible driving device 2 of drive arc crown frame 102 is provided on the arc crown frame 102；Steelframe 1
Multiple through-holes 103 are offered on the side wall contacted with wall, the inside of two vertical steelframes 101, which is vertically and fixedly provided with, laterally to be connected
Frame 104 is connect, the bottom of lateral connection frame 104 is provided with universal wheel 105, drive is also fixed between the lateral connection frame 104 of both sides
Dynamic device 2, driving device 2 is transversely arranged perpendicular to vertical steelframe 101, and the both ends of the driving device 2 are individually fixed in two
On the lateral connection frame 104 of side, the vertical steelframe 101 and arc crown frame 102 are docked by two and half sections of steelframes, wherein
The end set of one and half sections of steelframes has flexible targeting cyrto-rod 4, and the end of another half section of steelframe on the other side, which offers, leads
To hole 5, the flexible targeting cyrto-rod 4 extends to the docking that two and half sections of steelframes are realized in pilot hole 5, to form the vertical steelframe
101 or arc crown frame 102, the both ends (telescopic end and fixing end) of the driving device 2 be individually fixed in described two half section of steel
On frame.Multiple through-holes 103 for drilling machine drilling are offered on the side wall that steelframe 1 is contacted with wall.The driving device 2
For hydraulic pump or telescopic cylinder or electric pushrod.101 bottom of vertical steelframe is provided with wheel 3, is preferably laid in tunnel
Convenient for the track that wheel 3 moves, track can play the role of curing arch mobile route simultaneously.It can will be encircleed by chain when installation
Frame is connected with development machine, when needing arch to move, was moved development machine and is driven steelframe overall movement that can be moved to arch newly
Dig the position in tunnel.
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 and development machine are connected by chain, after the completion of development machine is pushed ahead, then arch is drawn
To under the tunnel newly tunneled.
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 between the hydraulic pump on arc crown frame 102 and two vertical steelframes 101 again, increases its pressure,
Arc crown frame 102 is set to be extended under the driving of hydraulic pump, distance increases under the action of hydraulic pump between two vertical steelframes 101
Greatly；Until vertical steelframe 101 and 102 outside side wall of arc crown frame are 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.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
