Description
Technical field
The utility model relates to a kind of air door body of wall, especially a kind of new mine product air door body of wall being selected to underground coal mine.
Background technology
Air door is the important ventilation equipment of underground coal mine, be arranged on do not allow distinguished and admirable or part distinguished and admirable by but need pedestrian or cross in the tunnel of car, stable and excessively car, pedestrian the safe ready of quality to mine ventilation system of its quality and performance plays an important role, and the stable of air door body of wall normally uses most important for air door.If down-hole complex geologic conditions is changeable, ore deposit pressure manifests obviously, mining influence in addition, tunnel compressive deformation causes the damage of air door body of wall, door frame distortions, facilities services cycle short, air door does not reach protrusion-dispelling requirement, and ventilation equipment is constructed, increasing difficult in maintenance, brings potential safety hazard to shaft production.Tradition underground coal mine is commonly used air door body of wall and is usually made up of brick, sand, cement, permanent air throttle thickness of wall body is between 500mm ~ 800mm, doorframe generally adopts iron structure, air door top added wood, in the tunnel that ore deposit pressure is larger, because the husky elastic properties of materials of wall body brick is very little, the phenomenons such as body of wall is very easily peeled, fall to be cut, ftracture, crush, distortion, affect air door and normally use.
Summary of the invention
The purpose of this utility model will overcome weak point of the prior art, provides that a kind of structure is simple, non-deformability is strengthened, the new mine product air door body of wall of long service life.
For achieving the above object, new mine product air door body of wall of the present utility model, comprise i iron lintel, doorframe, air door, upper beam, stent strut leg is symmetrical arranged in the wall of tunnel, the bottom of stent strut leg is provided with for spacing card cable, top is connected with the upper beam of arch, bottom is provided with bottom girder, the arcuate structure that described bottom girder becomes the anti-end to encircle, arc opening upward, bottom girder two ends and the stent strut leg of curved arch structure of the anti-end fix, and are welded together by pad, and the bottom girder of curved arch structure of the anti-end is formed by connecting by two joint support three road card cables; The air door be provided with in the arched frame surrounded by stent strut leg and upper beam described in reinforcement cage skeleton is located at the middle part of both sides stent strut leg 1 through doorframe, air door top is provided with i iron lintel, the top of i iron lintel is provided with air regulator, described reinforcement cage skeleton is interconnected by steel mesh reinforcement, and the outside of reinforcement cage skeleton is provided with concrete strengthening layer.
Described reinforcement cage skeleton is connected with stull.
Bottom curved arch structure bottom girder of the described anti-end and doorframe, formed angle is 50 ~ 120 °.
Beneficial effect: owing to have employed technique scheme, support bottom air door by air door anti-end arch skeleton, utilize reinforcement cage framework structure body of wall, earth reinforcing is mixed its outside employing, thus air door is reinforced, arch structure of the anti-end can be prevented and treated air door press the deformation of bottom caused with being subject to, thus ensure that the normal use of air door.Be specially adapted to tunnel and be arranged in the situation that coal seam easily deforms, or the ore deposit pressure at place, tunnel is obvious, air door body of wall needs reinforcement the place of process, is also applicable to the air door wall reinforcement of other non-coal mine down-holes.Its structure is simple, non-deformability is strengthened, long service life.Compared with prior art, tool has the following advantages:
1. adopted metal cage cage construction supports air door body of wall, makes air door resistance to compression, non-deformability reinforcement.After adopting the anti-end to encircle disjunctor reinforcing, ore deposit presses remarkable location ventilation equipment anti-pressure ability significantly to strengthen, and stability improves greatly, for the safety in production of mine is laid a good foundation;
2, use waste anchor rods to make reinforcement cage skeleton, waste steel bar net connecting framework, reduce construction cost, and good consolidation effect can be played;
3, originally permanent air throttle, the ventilation equipments such as air damper just need after building up 3 ~ 6 months to carry out repairing or rebuilding, after employing new technology, service life was more than 1 year, namely air door builds up in latter 1 year does not need to keep in repair again, rebuild, standard is constructed according to ventilation equipment on current ore deposit, a cost of materials rebuild by one group of forward and reverse air door and labour cost needs 1.5 ten thousand yuan, Underground presses remarkable place air door to rebuild 3 times by the every annual mean of original technique, pressure larger area, ore deposit has 10 groups of air doors, after adopting this technology, annual minimizing air door rebuilds number of times 30 times, annual accumulative can cost saving 450,000 yuan, therefore apply this technology and there is good economic benefit and social benefit.
