Description

The airborne temporary support device of development machine
Technical field:
The utility model relates to the airborne temporary support device of a kind of development machine, be a kind of device on the coal mine roadway development machine, carry out the equipment of temporary lining behind the roadway opening at empty top zone.
Background technology:
At present during the China's coal-mine roadway opening, after development machine tunnels out drift section, before permanent support is carried out in the tunnel, carry out temporary lining to the tunnel of new exposure.Current temporary lining work relies on heavy muscle power manual operations, be suspended on along roadway direction at empty top zone frame 2-3 bar steel pipe or square steel (being commonly called as forestope) and visit on the top board to empty top zone, top board is played the temporary lining effect, prevent that the top board roof fall from causing personal injury accidents.This supporting has following shortcoming: 1. forestope does not have setting load to the supporting of empty top zone, and security reliability is poor; 2. forestope is that point contacts with top board, can not the empty top zone top board effectively be protected; 3. complicated operating process, it moves armrest work industry, and the supporting activity duration is long, has reduced the excavation operation time; 4. during front-probe support, the staff exists potential safety hazard without any entering the empty top zone operation under the safeguard protection.
Summary of the invention:
The purpose of this utility model provides the airborne temporary support device of a kind of development machine, solve the existing shortcoming of using when present coal mine roadway is opened up of interim forestope, empty top zone is carried out safety, reliable, quick supporting, and account for the development machine headroom as much as possible less.
The purpose of this utility model realizes as follows: in the development machine left and right sides base is set, set gradually crossbearer, roll over stand, folding arm frame and bracing frame on every wing base, between the supported on both sides frame caving shield is set, crossbearer rear portion and base rear portion are hinged, crossbearer, roll over stand, folding arm frame and bracing frame are hinged successively, between the adjacent hinge member hydraulic jack are set.
In crossbearer, roll over stand, folding arm frame and bracing frame between the adjacent hinge member, the direct-connected mode of all or part of employing hydraulic jack, promptly the two ends of hydraulic jack are hinged on respectively on the adjacent hinge member, realize the action of opening and closing each other.
In crossbearer, roll over stand, folding arm frame and bracing frame between the adjacent hinge member, the indirect connected mode of all or part of employing hydraulic jack, it is articulated linkage respectively on the adjacent hinge member, the other end of two connecting rods and the piston rod end of hydraulic jack are hinged, the other end of hydraulic jack is hinged on one of them articulated elements, by the power of connecting rod transmission fluid compressing cylinder, realize the opening and closing action.
Having only caving shield is to be installed in the development machine back when rounding state, and remaining part is arranged in development machine cutting part both sides.Utilize the forward and backward bearing pin of cutting part, left and right base is fixedly mounted on the development machine, drive each the parts action of crossbearer, roll over stand, folding arm frame and bracing frame, make caving shield carry out supporting or withdrawal development machine top empty top zone by each hydraulic jack.
The beneficial effect that the utlity model has is: the mechanism that 1. utilizes oil pressure cylinder to drive applies certain setting load to back, makes top board be in the safety support state; 2. adopt whole caving shield design, caving shield is that face contacts with back, and the supporting area is big, can carry out supporting to empty top zone effectively; 3. utilize development machine that hydraulic power source is provided, by the control valve that is provided with, after driving finishes, empty top zone is carried out effective support, speed is fast, and operation is simple and reliable; 4. the supporting machine is installed in tunneling machine cutting portion, advances with development machine, has shortened support time, has improved Homes Using TV, improves the roadway opening drilling depth; 5. simple to operate, finish supporting by driving driver operation hydraulic valve handle, alleviated labor strength greatly, improved safety greatly, reduced site operation personnel's quantity, improved work efficiency.
Description of drawings:
Accompanying drawing is the structural representation of the airborne temporary support device of the utility model development machine.
The specific embodiment:
With reference to accompanying drawing, the base 2 that is installed in development machine 1 left and right sides is arranged, set gradually crossbearer 3, roll over stand 4, folding arm frame 5 and bracing frame 6 on every wing base 2, caving shield 7 is set between the supported on both sides frame 6, crossbearer 3 rear portions and base 2 rear portions are hinged, crossbearer 3, roll over stand 4, folding arm frame 5 and bracing frame 6 are hinged successively, between the adjacent articulated elements hydraulic jack are set.Utilize the forward and backward bearing pin of development machine 1 cutting part, left and right base 2 is fixedly mounted on the development machine 1, hydraulic jack is installed in inside at base 2, and by one group of connecting rod, be hinged together with top crossbearer 3, when oil cylinder stretched out, the mechanism that has launched on top in crossbearer 3 loads of driven in synchronism left and right sides, promoted caving shield 7 and removed to contact back.The long hydraulic jack on left and right sides crossbearer 3 tops is by linkage, the driving that gathering is provided, launches for roll over stand 4 and folding arm frame 5 and above mechanism thereof.The hydraulic jack that is provided with between roll over stand 4 and the folding arm frame 5 is used for when digging and draw in, makes mechanism avoid the restriction of head-room, can successfully make caving shield 7 upsets be opened to last the place ahead of development machine 1; When this hydraulic jack all stretches out, make roll over stand 4 and folding arm frame 5 form firm pillar again.The hydraulic jack of topmost is connecting linkage, can drive caving shield 7 and have very big amplitude when action, and form reliable gusseted when supporting, guarantees that setting load meets the requirements.Development machine 1 is when excavation operation, and this suspension device is in out-of-work state.Development machine 1 is retracted into the supporting district in shutdown, begins to handle multiple directional control valve, earlier choosing on the caving shield 7, folding arm frame 5 is bent, and roll over stand 4 is opened, and the action that these are a series of is turned to caving shield 7 before development machine 1 cutting head; Handle roll over stand 4 again, folding arm frame 5 stretches, caving shield 7 protracts again, stops.The miner is placed on steel band, anchor net above the caving shield 7, handles roll over stand 4,5 pull-ups in the other direction of folding arm frame again, and caving shield 7 keeps being basically parallel to back simultaneously, tentatively near top board, stops.After the miner aligns the steel band position, handle left and right sides crossbearer 3 and rise, contact fully and continue with top board up to caving shield 7 and exert pressure, form setting load.After waiting for that the miner all finishes the anchoring operation of back, decline left and right sides crossbearer 3,5 bendings of folding arm frame, roll over stand 4 counter-rotatings, caving shield 7 returns, suspension device is drawn in fully.
