Description
Technical field
This utility model is related to colliery tunnel support technology, particularly to a kind of jacking coal and rock suspension device.
Background technology
At present, known jacking coal construction technology uses shed shoring, the employing bolt-mesh-anchor support technique of only a few.
But, shed shoring has the problems such as construction intensity is big, safety coefficient is low, Master Cost is high；Meanwhile, shed shoring belongs to passive
Supporting, supporting effect is poor.When the construction of jacking coal is using bolt-mesh-anchor support, and the leaky roof, wall caving of easy generation, lead to roadway forming
Difference, supporting intensity difficult to reach requires.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of jacking coal and rock suspension device, and this device can carry
High bolting with wire mesh intensity is it is ensured that the integrity of roadway forming, and can ensure supporting effect of roadway, prevents anchor pole from losing anchor.
For achieving the above object, this utility model provides following technical scheme：A kind of jacking coal and rock suspension device, bag
Include anchor net, described anchor net is laid along coal mine roadway, is provided with supporting iron sheet between described anchor net and coal and rock, and the table of supporting iron sheet
Face and the top plate contact being arranged in coal and rock, described supporting iron sheet is provided with the eyelet of rectangle, anchor top line of the net tunnel section
Radially installed anchor pole, one end of anchor cable, anchor pole, the other end of anchor cable pass through the eyelet of supporting iron sheet and extend in coal petrography body.
Preferably, supporting iron sheet includes two parts, wherein the section semicircular in shape of Part I, the section of Part II
Rectangular, and two partly on be all provided with perforation.
Preferably, described tunnel both sides bottommost be provided with two anchor poles diagonally downward, and with horizontal plane angle be 15.
Using technique scheme, when jacking coal in tunnel is constructed, greatly improve bolt-mesh-anchor support range, fill
The favourable advantage of bolt-mesh-anchor support is waved in distribution, and construction intensity is low, low cost, safe, genus active support, and supporting effect is good.
When installing anchor shaft anchor cable, vibrate the coal body piece causing and fall on supporting iron sheet, supporting iron sheet is supported to coal body, makes supporting
Iron sheet, coal body form entirety with the top board being arranged in coal and rock, prevent top board coal body from continuing piece leakage, thus having reached jacking coal
During construction bolt-mesh-anchor support, top is not leaked, and improves bolting with wire mesh intensity, the intact purpose of roadway forming.

Specific embodiment
Below in conjunction with the accompanying drawings, by the description to embodiment, this utility model is described further：
As shown in Fig. 1 is to 4, a kind of this utility model jacking coal and rock suspension device, including anchor net 1, anchor net 1 is along colliery lane
Road is laid, and is provided with supporting iron sheet 2 between anchor net 1 and coal and rock, and the surface of supporting iron sheet 2 and the top board being arranged in coal and rock
Contact, supporting iron sheet 2 is provided with the eyelet 3 of rectangle, along one end of the radially installed anchor pole 4 in tunnel section, anchor cable 5 on anchor net 1,
Anchor pole 4, the other end of anchor cable 5 pass through the eyelet 3 of supporting iron sheet 2 and extend in coal petrography body, positioned at described tunnel both sides bottom
Portion is provided with two anchor pole 4 diagonally downward, and is 15 ° with horizontal plane angle, is easy to balance this utility model.
This utility model supporting iron sheet 2 includes two parts, wherein the section semicircular in shape of Part I, Part II
Rectangular in cross-section, and two partly on be all provided with perforation 3.
The installation method of this utility model jacking coal and rock suspension device comprises the following steps：
1), excavate coal mine roadway；
2), anchor net 1 is installed on coal mine roadway, and upper bolt 4 and anchor cable 5, anchor cable 5 are symmetrically installed on anchor net 1
It is arranged on coal mine roadway top, gib is carried out to coal mine roadway；
3), process supporting iron sheet 2；
4), supporting iron sheet 2 is installed between coal and rock and anchor net 1, and makes anchor pole 4 and anchor cable 5 pass through supporting iron sheet 2
Eyelet 3, install supporting iron sheet 2 when, subsequent cycle should be easy to along tunnelling directional spreding in the long side of supporting iron sheet 2
Construction；
5), using iron wire, supporting iron sheet 2 is fixed on anchor net 1；
6), the termination of anchor pole 4 and anchor cable 5 is driven into inside coal and rock, carries out permanent support.
This utility model supporting iron sheet 2 can be formed using waste and old oil drum cutting, and oil drum cap may be partitioned into semicircle shape iron sheet shield
Plate 2, oil drum ladle body cleavable rectangular in form iron sheet backplate 2, using waste and scrap, great amount of cost can be saved, material source enriches,
Processing and fabricating is simple, convenient using process.
This utility model, in construction and installation, after excavating excavated section of road, is tapped, is carried out gib.
The construction location of the square reserved in coal and rock, supporting iron sheet 2 is positioned between anchor net 1 and coal and rock, is allowed to square
The eyelet 3 of bit alignment ferrum supporting iron sheet 2, the minor face of supporting iron sheet 2 is towards direction of meeting head on, and uses 12#Iron wire is solid by supporting iron sheet 2
It is scheduled on anchor net 1.During usual construction anchor pole 4, vibration can be produced, make coal body slabbing loose nearby, cause leaky roof.By adding
Supporting iron sheet 2, using its globality, tenacity, no hole, free from flaw, plays provisional protection effect to loose coal body.Vibration
The coal body piece causing is fallen on supporting iron sheet 2, and supporting iron sheet 2 is supported to media, makes supporting iron sheet 2, be scattered coal body and top
Plate shape is integral, prevents top board coal body from continuing piece leakage, thus when having reached jacking coal construction bolt-mesh-anchor support, top is not leaked, tunnel
Shape intact purpose.
This utility model, when jacking coal in tunnel is constructed, greatly improves bolt-mesh-anchor support range, gives full play to
The favourable advantage of bolt-mesh-anchor support, construction intensity is low, low cost, safe, genus active support, and supporting effect is good.
Above-described is only preferred implementation of the present utility model it is noted that ordinary skill for this area
For personnel, on the premise of creating design without departing from this utility model, some deformation can also be made and improve, these all belong to
In protection domain of the present utility model.
