Three, summary of the invention
In order to solve the deficiency of prior art, the purpose of the utility model provides a kind of square chest shield machine that just can tunnel without explosive, can guarantee safety in production after the application and increases work efficiency, and can reduce production costs again.
The technical scheme that realizes the purpose employing of the utility model is: this square chest shield machine mainly is made up of square chest, pressure distributor, hydraulic cylinder, support claw, support arm, traveller, headstock and hydraulic boring unit; The combined type square chest inboard that is had operation path by polylith shaped steel fixed connection front and back opening together is provided with pressure distributor, and the top and bottom in the square chest are connected with upper and lower support arm, and upper and lower arm room is fixed with forward and backward traveller; Be rotatably connected to cylinder seat and connecting rod on the preceding traveller, be fixed with on the cylinder seat and pass the lifting hydraulic cylinder that connecting rod can make connecting rod go up and down; The front end of connecting rod is connected with headstock and hydraulic cylinder that headstock is rotated up and down respectively, and the other end of its hydraulic cylinder is movably connected in the front end of headstock, is fixed with hydraulic boring unit below the headstock; The medial surface of square chest is fixed with the oscillating motor that lower branch arm is swung, and the piston rod of its hydraulic cylinder is connected with lower branch arm; The inner face top of square chest is connected with the last support claw that advances by the piston in hydraulic cylinder bar; The rear portion, bottom surface of square chest is connected with the PF cylinder pressure; The tailpiece of the piston rod of PF cylinder pressure is connected with supporting cylinder, and the piston rod end at the two ends of supporting cylinder is fixed with down support claw.
The end of the piston rod of described lifting hydraulic cylinder is fixed with support roller, and the support roller pop-up has an end to be fixed on the cylinder seat, and the other end is fixed on the chain on the connecting rod.
After the work plane assembling is transported in each parts split of square chest; The staff is energized in square chest; With the pressure distributor work that hydraulic motor joins, following support claw, go up support claw and lean on hydraulic cylinder to advance square chest to be fixed on the crag, to make the rotation of hydraulic boring unit drill bit advance boring then; After the different parts of development end gets out a plurality of holes, rock is split down with the hydraulic pressure splitting machine.Support claw in the withdrawal, startup PF cylinder pressure is pushed ahead square chest integral body and is worked on.
The beneficial effect of the utility model is: under the promotion of hydraulic pressure; Connecting rod can slide up and down; Headstock can rotate up and down around connecting rod end; Oscillating motor promotes lower branch arm swings traveller, three kinds respectively motion can make hydraulic boring unit realize that three-dimensional motion is holed to the different parts of rock to split down rock.Do not blow up with dynamite during work, save the smoke evacuation time, accelerated driving speed; Development end periphery rock is not loosening, does not come off, and realizes safety in production; Reduced cost of production without explosive, directly ore recovery ratio has been improved at the exploitated ore position, and not having has explosion sound not disturb residents.This kind shield machine is simple in structure, and convenient in application can be widely used in occasions such as ore extraction, tunnel piercing.
Four, description of drawings
Fig. 1 is the structure connection layout of the utility model square chest shield machine.
Fig. 2 is for the tail end of square chest shield machine is fixed, the vertical view of propulsive units.
Five, the specific embodiment
In the accompanying drawings, the utility model square chest shield machine mainly is made up of square chest, pressure distributor, hydraulic cylinder, support claw, support arm, traveller, connecting rod, headstock and hydraulic boring unit; Square chest 2 is fixedly connected by polylith shaped steel forms the hexahedron that the front-back opening has operation path together; The advantage of its combined type square chest is to be convenient to transportation, and producers are safe and reliable in square chest.Square chest 2 inboards are provided with the pressure distributor 4 that is connected with hydraulic motor, and distributor 4 is supplied with each hydraulic cylinder hydraulic oil through oil supply line and made its work; Top and bottom in the square chest 2 are connected with upper and lower support arm 5,1, and 5,1 of upper and lower support arm is fixed with forward and backward traveller 6,3; Be rotatably connected to cylinder seat 14 and connecting rod 10 on the preceding traveller 6, be fixed with on the cylinder seat 14 and pass the lifting hydraulic cylinder 9 that connecting rod 10 can make connecting rod 10 go up and down; The front end of connecting rod 10 is connected with headstock 12 and the hydraulic cylinder 11 that headstock 12 is rotated up and down respectively; The other end of its hydraulic cylinder 11 is movably connected in the front end of headstock 12; Be fixed with hydraulic boring unit 13 below the headstock 12, this auger can realize that rotation advances boring; Piston rods in the hydraulic cylinder 11 are flexible make hydraulic boring unit 13 downwards, the certain angle that is inclined upwardly realizes multi-faceted boring.The medial surface of square chest 2 is fixed with the oscillating motor 15 that upper and lower support arm 5,1 is swung, and the piston rod of its hydraulic cylinder 15 is connected with lower branch arm 1, and oscillating motor 15 promotes lower branch arm 1 drive traveller through piston rod and swings.The inner face top of square chest 2 is connected with the last support claw 19 that advances by the piston in hydraulic cylinder bar, and this support claw 19 stretches out the side that square chest pushes up rock outward and plays the fixedly effect of square chest.The rear portion, bottom surface of square chest 2 is connected with PF cylinder pressure 16; The tailpiece of the piston rod of PF cylinder pressure 16 is connected with supporting cylinder 18; The piston rod end at the two ends of supporting cylinder 18 is fixed with down support claw 17, and following support claw 17 is used the side of pushing up rock with last support claw 19 and plays the fixedly effect of square chest; Support claw 19 in the withdrawal, start PF cylinder pressure 16 square chest integral body is pushed ahead, and the fixing branch support claw continues lower whorl work again.The end of the piston rod of described lifting hydraulic cylinder 9 is fixed with support roller 7, and support roller 7 pop-ups have an end to be fixed on the cylinder seat 14, and the other end is fixed on the chain 8 on the connecting rod 10.During lifting hydraulic cylinder 9 work, under the effect of chain 8, drive connecting rod 10 and go up and down, make hydraulic boring unit 13 realize moving up and down.The effect of described back traveller 3 is, when the needs back production, cylinder seat 14, connecting rod 10 and the parts that are attached thereto installed on the traveller 3 of back realize back production.
