The movable two-arm hanging wall anchor rod and anchor cable construction drill carriage
Technical field
The utility model relates to heading equipment under the coal mine, is applicable to large, medium and small moulded coal ore deposit, is to connect to adopt, connect pick, the required top-assisting anchor rod and anchor cable construction machinery in the comprehensive pick various tunnels of construction.
Background technology
At present, the main mode of all kinds of coal mine roadway drivings is adopted, is connected pick and combines pick for connecting, its support pattern is anchor pole, anchor cable, joist, anchor net combination supporting, adopt the monomer rig for top anchor shaft anchor cable construction great majority, the employing crawler-type lifting top and slope bolt and anchor construction drill is also arranged, as China Patent No. be: 200720102731.2 disclosed crawler-type lifting top and slope bolt and anchor construction drills, two drilling apparatus are arranged, an advance support, crawler type walking mechanism, advance support; Walking mechanism is by fluid motor-driven, rigging up platform on the frame of walking mechanism; The front portion of the below track unit of drilling machine platform is equipped with one and is pushed away the coal shovel plate; The advance support that a hydraulic oil cylinder type is housed foremost of platform, a side of advance support is equipped with a hydraulic drill rig that is used for the construction of anchor bar anchor cable; The top-assisting anchor rod and anchor cable construction hydraulic drill rig adopts two columns, and the slideway of move left and right part is contained on two columns, and hydraulic drill rig left or right rotation 30 degree; The hydraulic drill rig that is used for the construction of assisting anchor rod and anchor cable is loaded on drilling machine platform middle part one side, or the side of taking back, or the side that takes over, hydraulic drill rig revolves to the left or to the right and turn 90 degrees, the slideway of arranging before and after on drilling machine platform, being provided with, the column of hydraulic drill rig is seated on the slideway, and is moved forward and backward by the oil cylinder promotion rig integral body that is contained on the drilling machine platform.
There are following problem in this construction machinery and method for the top anchor shaft anchor cable construction adopts the monomer rig:
1, the tunnelling section is little: excavated section is generally at 15M
2About, when head-room surpasses 2 meters, must just can carry out top-assisting anchor rod and anchor cable construction by scaffolding.
2, on-mechanical equalization, the company of employing adopts, connects the mine top anchor shaft anchor cable construction of tunneling process and realized mechanization substantially, adopting the mine top anchor shaft anchor cable construction of combining tunneling process still is monomer rig manual work, and all driving technologies of assisting anchor rod and anchor cable construction all adopt the jackhammer construction, the thrust of perforating derives from people's arm and arm, and worker's labour intensity is big.Because assisting anchor rod and anchor cable construction mainly relies on manpower, the construction quality of assisting anchor rod and anchor cable can not fundamentally be guaranteed.
3, speed of application is slow, and building and remove scaffold when the construction section surpasses 2 meters needs a large amount of time.
4, efficient is low: because perforating quantity is many, the constructor is also many, causes operating efficiency low.
5, safety factor is low: the constructor is staggered operation in the high-altitude, and the job safety environment is poor.
There are following problem in this construction machinery and method for top-assisting anchor rod and anchor cable construction adopts crawler-type lifting top and slope bolt and anchor construction drill:
1, must two complete uses of crawler-type lifting top and slope bolt and anchor rig, what promptly use is each one that the hydraulic drill rig that is used for the construction of assisting anchor rod and anchor cable is loaded on the left and right side of drilling machine platform, the direction of rotation of two hydraulic drill rigs is different.Construct in the both sides that are emitted on the tunnel before and after two crawler-type lifting top and slope bolt and anchor construction drills successively when tunnelling.
2, advance and retreat the machine time long, the back work amount is big.Because during tunneling construction, the two bench drill machines of need drive or withdraw from driving face successively into, add dragging of cable, the time is long, and the back work amount is big.
3, to the complex geological condition bad adaptability.Meet complex geological conditions such as tomography, high gas district, high water aquifer, this drill carriage can not be finished the construction of the pre-gaging hole of gas, drawing-off gas hole, geology detecting hole, vibrations borehole.
4, the construction of anchor bar anchor cable does not reach zero lag, and is unfavorable to the control of lane group.
5, the workload of top-assisting anchor rod and anchor cable construction does not match, and the workload of crown drill is big, and the workload that group bores is little, influences support time, causes personnel's work holdup.
6, constructor's staggered operation in the high-altitude, the job safety environment is poor.
7, personnel selection is many, and two bench drill cars need 8 of manninves.
Summary of the invention
The purpose of this utility model solves the existing top-assisting anchor rod and anchor cable construction machinery of above-mentioned coal mine underground tunneling roadway exactly and has deficiency and problem, a kind of constructor's of reducing labour intensity is provided and reduces the constructor, driving speed and operating efficiency have been improved, create the safety work environment, particularly have superelevation tunnel and the work plane function that coal group carries out top pressing type temporary lining of meeting head on, adopt the full hydraulic system transmission, the movable two-arm hanging wall anchor rod and anchor cable construction drill carriage that explosion-proof performance and security performance are good.
The technical solution of the utility model is to achieve these goals:
