Abstract
A kind of telescopic arc crown frame of separation, including arc crown frame ontology, arc crown frame ontology are docked by two and half arc steelframes, and driving device is transversely arranged, and the both ends of driving device are individually fixed on two and half arc steelframes.The arch frame structure of the present invention is simple, install convenient, is recycled after detachable, reduces support cost.
Description
Technical field
The present invention relates to underground coal mine supporting field more particularly to a kind of telescopic arches.
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 telescopic arc crown frame of separation is proposed, effectively to ensure driving face
The relative safety of personnel.
In order to solve the above technical problems, present invention employs following technical solutions：
A kind of telescopic arc crown frame of separation, including arc crown frame ontology, arc crown frame ontology is by two and half arc steelframes pair
It connects, driving device is transversely arranged, and the both ends of driving device are individually fixed on two and half arc steelframes.
In the aforementioned telescopic arc crown frame of separation, in described two half arc steelframes, the butt end of one of them half arc steelframe
Upper perpendicular end surface offers pilot hole, and perpendicular end surface is fixed with guide rod on the butt end of another half arc steelframe, and guide rod is stretched
To realize the connection of two and half arc steelframes in pilot hole, and by the guiding role of guide rod and pilot hole to ensure two and half
Arc steelframe does not generate offset in the horizontal.
In the aforementioned telescopic arc crown frame of separation, the driving device is hydraulic pump, telescopic cylinder or electric pushrod.
The beneficial effects of the present invention are：
(1) arc crown frame is scalable, and the driving device on arc crown frame drives two and half arc steelframe lateral separations, makes arc top
Arch is close to wall, makes top plate and two help to be obtained for good supporting, you can be bored by the bolthole opened up thereon
Hole and rockbolt installation, when not using or needing mobile, by two and half arc steelframes of driving device driving laterally close to making arc top
Arch is detached with wall, you can carries out the dismounting or transfer of arc crown frame；
(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；
Description of the drawings
Fig. 1 is front view when two and half arcs steelframe of the present invention docks.
Fig. 2 is front view when two and half arcs steelframe of the present invention drives separation by driving device.
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 telescopic arc crown frame of separation, including arc crown frame ontology 1, arcs
Crown frame ontology 1 is docked by two and half arc steelframes 11, and driving device 2 is hydraulic pump, telescopic cylinder or electric pushrod, driving
Device 2 is transversely arranged, and the both ends of driving device 2 are individually fixed on two and half arc steelframes 11, in two and half arc steelframes 11,
Perpendicular end surface offers pilot hole 12 on the butt end of one of them half arc steelframe 11, on the butt end of another half arc steelframe 11
Perpendicular end surface is fixed with guide rod 13, and guide rod 13 is extended to realize the connection of two and half arc steelframes 11 in pilot hole 12, and logical
The guiding role of guide rod 13 and pilot hole 12 is crossed to ensure that two and half arc steelframes 11 do not generate offset, arc crown frame in the horizontal
It is distributed on ontology 1 equipped with bolthole 14.
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 drive.
Third walks：The both ends docking of arc crown frame ontology 1 is fixed on by the good vertical steelframe of opposite sides supporting in tunnel
The vertical steelframe top of both sides starts driving device 2 and two and half arc steelframes 11 is driven to move (separation) round about, until half
Until the outer wall of the outer wall of arc steelframe 11 and vertical steelframe holds out against tunnel.
4th step：By the bolthole 14 on steelframe to tunnel drilling, then squeezes 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
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
