Description
Technical field
The utility model relates to driving face advance support equipment under a kind of coal mine.
Background technology
Driving is the main method of underworkings developing under the coal mine.Top board and both sides rock just come out behind the tunnel initating, as not carrying out timely, effective support, back and rock stratum, both sides just lose support, produce tensile stress, and the tensile strength of rock are much smaller than the compressive strength of rock, under action of pulling stress, back and rock stratum, both sides unstability, and sinking and bending cause top, side formation damage, inbreak, the new tunnel of developing is damaged, roadway construction personnel and developing device security are constituted a serious threat.Driving face is forbidden the operation of sky top to using advance support between the permanent support under the relevant departments regulations coal mine for this reason.
In recent years, along with colliery comprehensive mechanization equipment constantly promotes, the application of large-scale high-performance heading equipment constantly increases underworkings digging area, and driving speed is constantly accelerated, and this has just proposed requirements at the higher level to the driving face advance support.Traditional driving face advance support equipment and method and use at present the large-scale high-performance heading equipment cover that mismatches influence integrated engineering progress and safety in production.How quick and easy, effectively driving face is carried out advance support, build the condition that provides for permanent supporting, be urgent problem behind the large-scale high-performance heading equipment of down-hole large-scale application.
Summary of the invention
Excavated section increases behind the large-scale high-performance heading equipment of colliery down-hole application, driving speed is accelerated in order to solve, support material increase become heavy, a dead lift and set up inconvenience, advance support is built and the unmatched problem of driving speed, the utility model provides a kind of advance support equipment of new structure, quick, safe, the efficient advance support needs of driving face under the satisfied coal mine under the new situation.
The utility model driving face advance support equipment comprises and protects ejection device and left and right sides protection unit two parts.Protecting ejection device mainly is made up of the sliding card of quick-clamping assembly, front-axle beam, the fixing card of front-axle beam, interior slide bar, outer slide bar, the jack that stretches, wall supporting jack stay pipe, wall supporting jack, face guard etc. by shift sleeve structure, one side of face guard is connected with articulated manner with front-axle beam, links to each other with the wall supporting jack by the wall supporting jack stay pipe that shift sleeve structure is arranged in the middle of it.The left and right sides protection unit mainly protects interior slide bar, side by the sliding card of quick-clamping assembly, curb girder, side and protects outer slide bar, the fixing card of curb girder, side and protect the jack that stretches etc. and form.
The technical scheme in the invention for solving the technical problem is: the permanent canopy supporting and protection structure of the i iron that utilizes the down-hole to put up, to protect ejection device with the sliding card of six groups of quick-clampings assembly hangs on the permanent ceiling of the i iron portion crossbeam, unclamp the fixing card of front-axle beam of front-axle beam both sides, flexible jack in utilizing in the slide bar promotes front-axle beam and stretches out forward, support the new i iron of placing in the regional top of new developing, work the top effect of protecting.Simultaneously, have the wall supporting jack stay pipe of shift sleeve structure to utilize its shift sleeve structure to skid off forward with front-axle beam with same speed, operation wall supporting jack opens to and the front-axle beam upright position the hinged face guard of one side and front-axle beam, work plane is met head on to block, prevent the wall caving of meeting head on.
Equally, respectively the left and right side protection unit is fixed on the supporting leg of the permanent canopy of the i iron of having put up side with the sliding card of six groups of quick-clampings assembly, fore side protects flexible jack, makes curb girder extend out to the front-axle beam same position forward, be aided with baffle plate, carry out the protection of new development work left and right side.So just build the advance support canopy of two canopy distances forward, be formed with the working space of three protection, so that the constructor clears up rock in the tunnel, spoil, silt coal etc., after cleaning is finished, left and right sides face supporting leg i iron is installed, and the new i iron of placing in itself and top is connected, constitute the permanent canopy supporting and protection structure of new i iron.
After treating that the permanent support canopy builds up, front-axle beam, face guard, curb girder are regained, and development machine is pushed ahead.After treating that development machine tunnels two canopies distance more forward, the distance of two canopy distances released front-axle beam forward by the flexible jack of operation, with the fixing card of front-axle beam, block the permanent beam of front end, unclamp the sliding card of caudal end quick-clamping assembly, flexible jack is shunk, outer slide bar etc. is moved forward two canopy distances, realize that the whole ejection device that protects moves forward automatically.Fore side protects the distance that two canopy distances released curb girder forward by flexible jack, with the fixing card of curb girder, block the permanent beam of front end, unclamp the sliding card of caudal end quick-clamping assembly, making side protect flexible jack shrinks, side is protected outer slide bar etc. move forward two canopy distances, realize the whole reach automatically of left and right sides protection unit.So circulation is worked continuously.
The beneficial effects of the utility model are: driving face advance support problem when having solved the large-scale efficient development machine of colliery down-hole application, alleviated labor strength, and improved operating efficiency and safety, and simple in structure, easy to operate.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, outer slide bar (5) is fixed in the transverse beam of the permanent canopy of i iron (9) with six groups of quick-clampings sliding card assemblies (1), the flexible jack (6) of the fixing card of front-axle beam (3), operation that unclamps front-axle beam (2) both sides stretches out it forward, thereby slide bar (4) and front-axle beam (2) stretch out forward in promoting, support the new i iron of placing (10) in the regional top of new developing, be aided with backing plate, form top braces, prevent roof fall.
When front-axle beam (2) stretches out, there is the wall supporting jack stay pipe (7) of shift sleeve structure to utilize its shift sleeve structure to skid off forward with front-axle beam (2) with same speed, operation wall supporting jack (8) is opened with front-axle beam (2) the hinged face guard (11) of one side and front-axle beam (2) and is in vertical position, formation meets head on to protect, and prevents the wall caving of meeting head on.
