Description
Affiliated technical field
The utility model relates to engineering machinery, is specifically related to the structure of hydraulic pressure extractor.
Background technology
The key of extractor is how its stressed principle of pile pulling and the i.e. stake of lockset connect with the force part.Extractor in the past has two kinds: a kind of BZF20 of being type hydraulic pressure extractor, and its adopts is the oil cylinder main body down, jack-up upwards, its defective has: 1, volume ratio is bigger, moves difficulty; 2, its lockset is a steel ring greater than the stake footpath, link to each other by wire rope or the same lever arm of force of a hard steel pole, because lockset is to produce auto-lock function in loading process, when pulling up stake, will be out of shape partially contact stake two wall pressures with steel ring, so can only be used for pulling out bad stake; 3, owing to be that self-locking by steel ring and stake produces stressed contact during pile pulling, when the stake of pulling out different size and form, to use different locksets; Also have a kind of YD of being type hydraulic pile driver, it be a kind of self-propelled based on piling, pile pulling is the equipment of assisting, its defective has: when 1, it will pull out stake, be to adopt the wedge shape auto-lock function, stake must be vertical substantially, and upper orifice can not be out of shape, otherwise lockset advances not go; If 2 stakes of pulling out bad stake or other form must be changed lockset; 3 owing to be in the locking of the top of stake during pile pulling, adds lockset itself, so the volume ratio of equipment is taller and bigger.
In engineering practice, a lot of occasions all need this equipment of pile pulling, and particularly road overlays and transforms, and the track is widened to transform to wait and all former guardrail stake will be pulled up, again pickling is zinc-plated utilizes again, this stake that just requires to pull up can not be out of shape, and is exactly because traffic accident with ining addition, cause guardrail stake (column) quilt to be driven a vehicle to hit bend after, will in time extract row repairs again, the steel sheet pile of squeezing in the building, cylindrical steel tube post, timber etc. all will pull up it and utilize, and can not be out of shape.This just requires pile pulling convenient, fast, need not often to change lockset.
Summary of the invention
The purpose of this utility model is: a kind of hydraulic pressure extractor is provided, and this extractor volume is little, pull out force is big, self-locking is simple, conveniently moving, pile pulling are convenient, fast, need not to change lockset.
Technical solution of the present utility model is: this extractor mainly is made of underframe, column frame, hydraulic jack, lockset plate, underframe is formed by fixedly connecting by cradling piece, connect base plate between cradling piece, form column frame on the fixedly connected underframe of several root posts, the column upper end is connected with top board, the piston rod pin-and-hole that the piston rod of two-way cylinder is inverted through being connected on the piston rod downwards is connected with base plate by steady pin, the fixedly connected clip of cylinder body outer rim, the lockset plate of key way with lock is fixedlyed connected with clip through strengthening otic placode.

The specific embodiment
As shown in Figure 1, this extractor is mainly by underframe 4, column frame 3, hydraulic jack, lockset plate 8 constitutes, underframe 4 is half shaped as frame by three channel-section steels and is formed by fixedly connecting, be advisable and lean forward preventing for the two stressed channel-section steel length that prevent to lean forward will surpass institute's pile pulling outside dimension than length, bottom lifting surface area when having base plate 13 to link to each other between the two stressed channel-section steels with the increase pile pulling, sink when preventing the extractor pile pulling, form column frame 3 on three fixedly connected underframe 4 of square steel column, wherein two centers, front will surpass the center of institute's pile pulling, the column upper end is connected with top board 1, be connected triangle stiffener 14 with the bottom at its top for strengthening the front two root post bending resistances ability of drawing, the fixedly connected clip 9 of the outer rim of the cylinder body 7 of two-way cylinder, the lockset plate 8 of key way 17 with lock is fixedlyed connected with clip 9 through strengthening otic placode 15, be connected with piston rod pin-and-hole 16 on the oil cylinder piston bar 11, the two-way cylinder of band tank filler sleeve 6 is downward its piston rod of inversion shape and is connected with base plate by steady pin.
When preventing that cylinder body from leaning forward to whole friction, two rollers 12 of installation below top board 1 of producing of framework; In order to prevent that oil cylinder from producing lateral force and causing the oil cylinder distortion, adorn two rollers 10 at the two ends of lockset plate 8 and move up and down along the column rear side; For the moving conveniently moving in field, on underframe, to adorn two and move wheel 5, moving hand-rail 2 connects on the top board 1, holds the handrail post-tensioning and tilts promptly removable.
During pile pulling, extractor is in place, make cylinder body be close to the stake that need extract, chain twined for two weeks in stake, tension back chain button is put into the "T"-shaped self-locking of lockset plate chain groove and is fixed, the hydraulic shock motive power outputting apparatus that connects outward links to each other with extractor, and self-locking pile body in the stressed back of cylinder body rising chain together rises, after the oil cylinder stroke one-time-reach-place if can not pull out stake, then oil cylinder oil return, cylinder body descends, and chain glides, and repeats to pull out until stake to be pulled up again.
The utlity model has following advantage: 1,, reduced the machine stress position, dwindled the machinery integral height because hydraulic jack is inverted; 2, use chain stressed even, can not cause the pile body distortion to guarantee around the loading process king-pile; 3, very big lateral force is arranged when pile pulling, oil cylinder is tilted to the column direction, and oil cylinder can not bear the effect of lateral force, for preventing that friction from occurring in the top board bottom two guide rollers are housed, also there are two guide rollers at lockset plate two ends, the lateral force of oil cylinder is passed to two front columns of framework, make sliding friction become rolling friction, resistance reduced when oil cylinder was risen; 4, be the place conveniently moving, two Φ 200mm rubber wheels are housed at the rear portion, hold the handrail post-tensioning and tilt promptly removablely, during static keeping flat, the wheel bottom is equal with base of frame, stressed when not participating in pile pulling; 5, this extractor no matter be good stake or by driving hit curved, knock down can by high-strength anchor chain bundle around after 2 weeks anchor chain is suspended to the fixing lockset plate of cylinder body on, firmly lock by the stressed stake-anchor chain-lockset plate that makes of hydraulic pressure, oily then top application power rises, and stake is pulled up.
