Abstract

The utility model provides a coal road tunnelling temporary support device, belongs to the coal mine tunnel supporting technology field, has solved the existing colliery underworkings tunnelling problem that exists of temporary support device head -on, and it contains three parallel arrangement's spy roof beam, is provided with two gallowss respectively three the same one end of visiting roof beams, the width of gallows is greater than the width of visiting the roof beam, is provided with a jackscrew respectively in the left and right sides of gallows and will visits the roof beam location, can change the angle of visiting the roof beam through the adjustment jackscrew to the level of adaptation coal road turns to, the height of gallows suits with visiting the depth of beam, and the bottom plate of gallows passes through the bolt and visit the roof beam to be connected, prevents that the coal road from facing upward to one side or bowing and visit the roof beam slippage when tunneling to one side, and in order to change the angle of visiting the roof beam, the hole that the bolt of setting on the gallows bottom plate passed is the arc hole, and the arc hole of two gallowss on every spy roof beam sets up relatively, be provided with two metal protection nets three parts that set up beyond the gallows of visiting the roof beam, the utility model is used for coal road tunnelling temporary support.

Description

A kind of coal roadway tunneling temporary support device
Technical field
The utility model belongs to colliery tunnel support technical field, is specifically related to a kind of coal roadway tunneling temporary support device.
Background technology
At present, domestic existing coal mine down-hole tunnel boring head temporary support device, as: underground coal mine temporary support for drivage face equipment (publication number CN203531931U), a kind of front beam for dig heading face temporary support device (publication number CN204646278U), longeron alternating expression temporary support for drivage face support (publication number CN203756209U), automatic paving, networking temporary support device for drivage (publication number CN204140110U) etc. adopt support, hook, forestope to be interconnected technical scheme, visit temporary support device before belonging to suspension type or frame canopy formula.Although use above-mentioned existing apparatus can realize boring head immediate support in coal roadway tunneling meets head on temporary lining process, but rise and fall at coal roadway tunneling inclination angle, level is when turning to, the problem such as still there is assembling and disassembling complex procedures, back timber and top net can not synchronously set up.
Summary of the invention
The purpose of this utility model is the problems referred to above existed to solve existing coal mine down-hole tunnel boring head temporary support device, and provide a kind of coal roadway tunneling temporary support device, its technical scheme is as follows:
A kind of coal roadway tunneling temporary support device, it comprises three spy beams be arranged in parallel, and the identical one end visiting beam at three is respectively arranged with two suspension brackets, each suspension bracket is provided with the connectors such as otic placode, is used for spy beam to be connected with permanent suspension device; The width of described suspension bracket is greater than the width visiting beam, is respectively arranged with a jackscrew will visits beam location in the left and right sides of suspension bracket, can change the angle visiting beam, turn to the level adapting to coal road by adjustment jackscrew; The height of described suspension bracket adapts with spy depth of beam, the base plate of suspension bracket is connected with spy beam by bolt, beam slippage is visited when preventing coal road from facing upward oblique or advancing to the dip, in order to the angle visiting beam can be changed, the hole that the bolt that suspension bracket base plate is arranged passes is arcuate socket, and the arcuate socket of two suspension brackets that every root is visited on beam is oppositely arranged; The part arranged beyond suspension bracket visiting beam at three is provided with two panels Chain Link Fence, in order to easy accessibility, the surrounding of every sheet Chain Link Fence is provided with frame, two panels Chain Link Fence load is the upper surfaces of three spy beams visit corbels by three, the relative side of two panels Chain Link Fence is connected with the upper surface visiting beam being positioned at centre respectively by two or more right angles hook, the spy beam being positioned at centre is provided with and links up with corresponding dog hole with right angle.
The beneficial effects of the utility model are: down-hole dismounting is flexible, reduce labor intensity, the functions such as spacing anti-skidding, adjustable angle, the back timber of boring head temporary lining and the synchronous erection of top net can be realized, stop empty top operation, prevent the inbreak of driving face roof strata and early stage absciss layer from damaging staff, increase work efficiency.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the exploded view of Fig. 1;
Fig. 3 is an enlarged drawing visiting two suspension brackets on beam.
detailed description of the invention:
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of coal roadway tunneling temporary support device, it comprises three spy beams 1 be arranged in parallel, and the identical one end visiting beam 1 at three is respectively arranged with two suspension brackets 2, each suspension bracket 2 is provided with the connectors such as otic placode 2-1, is used for spy beam 1 to be connected with permanent suspension device; The width of described suspension bracket 2 is greater than the width visiting beam 1, is respectively arranged with a jackscrew 2-2 is located by spy beam 1 in the left and right sides of suspension bracket 2, can change the angle visiting beam 1, turn to the level adapting to coal road by adjustment jackscrew 2-2; The height of described suspension bracket 2 adapts with the height visiting beam 1, the base plate of suspension bracket 2 is connected with spy beam 1 by bolt 2-3, beam 1 slippage is visited when preventing coal road from facing upward oblique or advancing to the dip, in order to the angle visiting beam 1 can be changed, the hole that the bolt 2-3 that suspension bracket 2 base plate is arranged passes is arcuate socket 2-4, and the arcuate socket 2-4 of two suspension brackets 2 that every root is visited on beam 1 is oppositely arranged; The part arranged beyond suspension bracket 2 visiting beam 1 at three is provided with two panels Chain Link Fence 3, in order to easy accessibility, the surrounding of every sheet Chain Link Fence 3 is provided with frame 3-1, two panels Chain Link Fence 3 is carried on a shoulder pole the upper surface visiting beam 1 at three and is held up by three spy beams 1, the relative side of two panels Chain Link Fence 3 is connected with the upper surface visiting beam 1 being positioned at centre respectively by two or more right angle hook 3-2, the spy beam 1 being positioned at centre is provided with and links up with dog hole 3-3 corresponding to 3-2 with right angle.
