Description
Technical field
The invention belongs to the suspension device of underground coal mine coal excavation apparatus, particularly a kind of bump tunnel step type energy-absorbing erosion control support.
Background technology
Deep mining is the inexorable trend of coal industry development, deep coal and rock composition architectural feature, deformation-failure character, fault offset feature are all obviously different with superficial part from engineering response feature, more easily bring out rock blast hazard, cause down-hole heavy damage and personnel casualty accidents, with adopting dark increase, stress in coal body increases, and the possibility that bump occurs is larger, and particularly the danger of return airway generation bump is also larger.Research statistics shows, the bump of more than 75% occurs in tunnel, particularly within the scope of work plane 0 ~ 100m advance support.
Present shallow mining develops to deep mining gradually, and roadway support form also remains on anchor pole, anchor cable, metallic support, metal collapsible timbering, shotcrete etc., these support pattern supporting intensities are low, labour intensity is large, cost is high, poor stability, seriously constrain colliery highly effective and safe production requirement.At present, existing advanced hydraulic support mainly has the following disadvantages: (1) part advance timbering moving manner easily causes and repeatedly supports top board, causes roof cracking, is unfavorable for roadway maintenance.(2) tunnel adopts bolt and cable anchor supporting, understands some and leaks outside, affect advance timbering back timber and contact effect with back in wall.(3) advance timbering has higher protective capacities to roof and floor, but support impact resistance is poor, and the protective capacities of side direction and stability deficiency.(4) be placed with various production corollary equipment in advance support section, the size of these equipment, position and advance timbering are not easily supporting, be not as flexible as individual prop.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, a kind of supporting capacity and strong shock resistance are provided, efficient, the safe and reliable bump tunnel step type energy-absorbing erosion control support that can certainly move.
The technical scheme that technical solution problem of the present invention adopts is: bump tunnel step type energy-absorbing erosion control support comprises base, back timber, hydraulic vertical prop one, hydraulic vertical prop two, extensible canopy one, extensible canopy two, be characterized in that the top of every pack support is by two parallel back timbers, below forms framework by two parallel bases, on between two parallel back timbers and base, lower symmetry connects with three jack one, four hydraulic vertical props two are arranged with above two parallel back timbers, the symmetrical hydraulic vertical prop one that three horizontal directions are housed on the lateral surface of two parallel bases and back timber, the external end head of base with the hydraulic vertical prop one on back timber is connected lower end and the upper end of extensible canopy one respectively, between two parallel back timbers and base, quadric chain is housed, quadric chain is by upper connecting rod, lower link and cant beam composition, upper connecting rod, lower link and cant beam are and are hinged, connect with extensible canopy two between top back timber between two pack supports, connect with jack two between base, energy-absorbing erosion control hydraulic vertical prop is provided with between the back timber often organized and base rear and front end.
The invention has the beneficial effects as follows: after bump tunnel step type energy-absorbing erosion control set cap installs hydraulic vertical prop, back timber can be contacted according to design attitude with the contact position of top board, enhance set cap stressed, overcome support to move in frame process to cause and repeatedly support top board, cause the problem of roof cracking, effectively dodge bolt and cable anchor supporting to leak outside part in wall, enhance set cap and contact effect with back.Bump tunnel step type energy-absorbing erosion control support has higher protective capacities to roof and floor, also has higher protective capacities to side direction, and the design of energy-absorbing erosion control hydraulic vertical prop uses and adds support impact resistance.Bump tunnel step type energy-absorbing erosion control support height can regulate with energy-absorbing erosion control hydraulic vertical prop, and lateral width available hydraulic column one and jack one regulate, and the rectangular shaped roadways being applicable to sizes uses, and can realize from moving.Bump tunnel can greatly reduce roadway deformation, labor strength and cost of production, improve operational security, accelerate advance support fltting speed, meet the requirement of high-yield and high-efficiency fully-mechanized mining working after using step type energy-absorbing erosion control support to carry out strengthening supporting.

Detailed description of the invention
Embodiment, with reference to accompanying drawing 1 ~ 3, bump tunnel step type energy-absorbing erosion control support forms framework by two parallel back timbers 1, below by two parallel bases 7 above every pack support device, symmetrically up and down between two parallel back timbers 1 and base 7 connects with three jack 1.Four hydraulic vertical props 23 are arranged with above two parallel back timbers 1, the symmetrical hydraulic vertical prop 1 that three horizontal directions are housed on the lateral surface of two parallel bases 7 and back timber 1, the lower end of the extensible canopy 1 of vertical connecting and upper end respectively on the external end head of the hydraulic vertical prop 1 on base 7 and back timber 1.Between parallel base 7 and back timber 1, quadric chain is housed, quadric chain is made up of upper connecting rod 8-1, lower link 8-2 and cant beam 8-3.Connect with the extensible canopy 2 10 of level between top back timber 1 between two groups of devices, connect with jack 26 between base 7.Energy-absorbing erosion control hydraulic prop 4 is provided with between the back timber 1 often organized and the rear and front end of base 7.With reference to accompanying drawing 4, for the annexation between whole device and country rock 11, hydraulic vertical prop 23 above back timber 1 is connected with upper country rock 11, extensible canopy 1 outside hydraulic vertical prop 1 is connected with both sides country rock 11, base 7 is connected with country rock 11, is provided with energy-absorbing erosion control hydraulic vertical prop 4 between base 7 and back timber 1.The rectangular shaped roadways of the applicable sizes of this device uses and can realize from moving.
The operating principle of bump tunnel step type energy-absorbing erosion control support is impacted owing to adopting jack 1 to connect the ground pressure adopting hydraulic vertical prop 1 and extensible canopy 1 can bear side, tunnel country rock 11 outside both sides between two parallel back timbers 1 and base 7.The back timber 1 energy-absorbing erosion control support 4 be provided with above between hydraulic vertical prop 23 and back timber 1, base 7 can resist the pressure of upper and lower country rock 11 completely, and the bump of whole device to tunnel plays omnibearing support action.
