Abstract
The utility model discloses one kind to be used for half-edge coal seam tunnelling supporting metal integral support, including top beam, row's bavin, metal mesh, basketry piece, coal seam, I-steel leg and connecting plate, the basketry piece is set to the lower end surface of the roof, the metal mesh is set to the lower end surface of the basketry piece, row's bavin is set to the lower end surface of the metal mesh, the top beam is set to the lower end surface of row's bavin, is fixedly connected between the lower end of the top beam and the I-steel leg by the connecting plate.Compared with prior art, in order to solve, the formal supporting of high side during coal roadway tunneling of this mine is easy left and right displacement deformation spacing increase to the utility model and bracket hired thug stick up foot and high side coal seam is caused to leak the supporting problem emitted.After the utility model, supporting metallic support in high side coal seam forms entirety, reduces coal seam and collapses the risk risked, improves safety guarantee.
Description
Technical field
The utility model relates to a kind of mining industry equipment, more particularly to one kind to be used for half-edge coal seam tunnelling supporting metal
Integral support.
Background technique
The basal conditions of country's digging laneway roadway support at present, domestic coal mine mainly have 2 kinds at present, and a kind is simple gold
Belong to bracket support form, top plate and two are helped to carry out formal supporting using mining i beam processing metallic support.1 kind is anchor rete cord
Supporting carries out formal supporting to top plate and lane side using anchor pole+anchor cable+metal mesh.This 2 kinds of support patterns are respectively present following ask
Topic, current simple wire bracket, by pressure influence, are easy to stick up foot and cause metallic support to collapse to emit, while high side is come during supporting
It presses after-poppet to be easy left and right displacement, bracket spacing is caused to increase, leakage occur and emit；Bolt-mesh-anchor support, in working face extraction, because
Anchor Cable Anchorage deformation is serious, and anchor cable withdraws difficulty, and security threat is big, and if do not withdrawn anchor cable, coal mining machine cut is be easy to cause to anchor cable
Accident.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems and provides a kind of for the pick of half-edge coal seam tunnel
Into supporting metal integral support.
The utility model achieves the above object through the following technical schemes:
The utility model includes that top beam, row's bavin, metal mesh, basketry piece, coal seam, I-steel leg and connecting plate, the basketry piece are set
It is placed in the lower end surface in the coal seam, the metal mesh is set to the lower end surface of the basketry piece, and row's bavin is set to the metal
The lower end surface of net, the top beam are set to the lower end surface of row's bavin, lead between the lower end of the top beam and the I-steel leg
The connecting plate is crossed to be fixedly connected.
Further, row's bavin is that evenly distributed wooden cylindrical body is constituted.The wooden cylindrical body is 1.2m long, diameter
20mm。
Further, the I-steel leg is more, is fixedly connected with reinforcing I-shaped between adjacent two I-steel legs
Steel.
Further, the basketry piece is the multi-disc bamboo sheathing that bamboo chip is woven into.The width of the basketry piece is 0.6m, a height of 0.8m.
The utility model has the beneficial effects that:
The utility model is a kind of for half-edge coal seam tunnelling supporting metal integral support, with prior art phase
Than the utility model is easy left and right displacement deformation spacing increase to solve the formal supporting of high side during coal roadway tunneling of this mine
Sticking up foot with bracket hired thug causes high side coal seam to leak the supporting problem emitted.After the utility model, high side coal seam supporting gold
Belong to bracket and form entirety, reduces coal seam and collapse the risk risked, improve safety guarantee.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is part A partial enlarged view in Fig. 1；
Fig. 3 is the side structure schematic diagram of the utility model.
In figure: 1- top beam, 2- row bavin, 3- metal mesh, 4- basketry piece, the coal seam 5-, 6- I-steel leg, 7- connecting plate, 8- are reinforced
I-steel, 9- anchor pole.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
The utility model includes top beam 1, row's bavin 2, metal mesh 3, basketry piece 4, coal seam 5, I-steel leg 6 and connects as shown in Figure 1:
Fishplate bar 7, the basketry piece are set to the lower end surface of the roof, and the metal mesh is set to the lower end surface of the basketry piece, institute
The row's of stating bavin is set to the lower end surface of the metal mesh, and the top beam is set to the lower end surface of row's bavin, the lower end of the top beam
It is fixedly connected between the I-steel leg by the connecting plate.
Further, row's bavin is that evenly distributed wooden cylindrical body is constituted.The wooden cylindrical body is 1.2m long, diameter
20mm。
Further, the I-steel leg is more, is fixedly connected with reinforcing I-shaped between adjacent two I-steel legs
Steel 8.
Further, the basketry piece is the multi-disc bamboo sheathing that bamboo chip is woven into.The width of the basketry piece is 0.6m, a height of 0.8m.
Anchor pole 9 is the anchor pole that the prior art needs to be arranged when establishing.
The mine of the utility model application belongs to coal and gas outburst mine, and seam inclination is average at 48 ° or so, coal roadway tunneling
When tunnel be section, formal supporting using metal integral support cooperation anchor rete cord carry out supporting, i.e., coal seam high side side use
Metal integral support supporting, roof and low-cut side use bolt-mesh-anchor support.The processing of metal integral support and support pattern are as follows:
One piece of connecting plate is respectively welded in original simple wire set cap and bracket hired thug lap-joint, and connecting plate both sides are respectively constructed a spiral shell
Keyhole, it is another to process a support rod using the round steel cooperation steel plate of φ 16mm, set cap and bracket hired thug are connected by bolt
