In one embodiment of the present of invention, operation principle of the invention：
This pile-drawing machine can pile pulling stake footpath scope≤1000mm, it is adaptable to which the pile body of variously-shaped and material, construction cost is low,
Process is simple, is easy to operation, and speed of application is fast, simple and practical.The present invention is a kind of hydraulic jaw type clamping mechanical pile pulling device, bag
Include：Hydraulic tongs clamping device, including hydraulically operated fixture, realize that the stake in clamping device is implemented to hold tightly or unclamped；Changeable clamp,
It is installed on hydraulic clamp, matched clamp can be changed according to piles with different footpath and pile-type, makes to be produced between stake and pile pulling device and rub
Wipe power and be more than frictional force of the soil body to stake.Shaking device, is produced using motor and shaken, and the stake to being embedded in underground carries out drawing, makes
Stake produces loosening；Hydraulic lift.The present invention can easily open or close tong arm, so that clamping device is close to stake
Surface, will be squeezed between the stake on ground and the soil body using shaking device and loosened, and reduce frictional force, it is ensured that pile body is complete during pile pulling
It is good, while above carrying and extracting stake using site machinery (truck crane or excavator)；The device is not limited by geographic, can be by
Squeeze into plane, it is domatic in the pile body such as round stake, square pile extract, do not destroy pile body, the present invention can at utmost protect original stake
Body, the stake of extraction secondary can be utilized, and save investment.
The pile pulling flow that the present invention takes is as follows：
1st, corresponding fixture is selected (to pull out circular stake using circular shaped motion fixture, the side of pulling out according to pile-type and stake specification before pile pulling
Stake and Section-steel Piles use square fixture, and the square and circular clamp length of side and diameter are consistent with institute pile pulling specification, because of live stake species
And specification is basically identical, therefore floating holder only needs one to two sets substantially, will not frequently change), fixture is passed through into bolt and hydraulic pressure
The connection of jaw type clamping device is integral.
2nd, it is connected with crane by pile-drawing machine top both sides hanger 8 using wirerope, or logical pile-drawing machine top center
Attachment means are connected (tie point of top center can horizontal rotation angle) with excavator swing arm.
3rd, clamping clip is opened by synchronous electric hydraulic lifting jack 2, opening degree extremely can be from pile body side or top by stake
It is inserted in and is advisable.Pile-drawing machine is moved to stake top (or stake side) using crane or excavator swing arm, it is very heavy using synchronous electric hydaulic
Pile-drawing machine clamping clip is closed on top 2, and pile holder is tight, starts pile pulling.
4th, pile-drawing machine top jarring machine 7 is started, shaking force is delivered to clamping machine by jarring machine 7 by the supporting leg that is rigidly connected
Structure, then be delivered to pile body, makes stake increase with soil body gap using vibrations, and frictional force reduces, then by crane or excavator by stake
Lift cramping arrangement, the soil body is proposed by stake.
5th, the stake of extraction is still clamped to be positioned over crane or digging machine and piles up position, using synchronous electric hydraulic lifting jack 2
Clamp is unclamped, the placement of stake is completed, pile pulling is completed, continues the extraction work of next pile.
Can be flexible from pile body side or stake top face clip pile, clip pile mode using hydraulic jaw type clamping device；Hydraulic jaw type is pressed from both sides
Tight device opening degree is big, and pile body can be accurately clamped without precisely operation during clip pile, for being difficult accurate sight water is medium
The clamping for examining the stake of positioning is particularly convenient；The folding of clamp is controlled using electric hydraulic lifting jack 2, folding speed is fast.Using top
Portion's jarring machine 7, clamping device is delivered to by rigid leg 6 by shaking force, then passes to pile body, is made between stake and the soil body using vibrations
Gap increases, and frictional force reduces, then stake is lifted out into the soil body by crane or excavator；The required supporting lifting means scope of application
Extensively, the plant equipment such as crane or excavator can be had with scene to be connected, as lifting means, connected mode flexibly, is hung
Car is connected using steel wire rope with the suspension of equipment both sides hanger 8, and excavator is connected using swing arm with top center rotating shaft bearing pin, connection
Mode simple and fast, it is safe and reliable.To hang the formula of pulling out, clamping device is open-close type hydraulic clamping device to the present apparatus, by clamping device
Opened using hydraulic system, directly clamp the lower portion of pile crown one, clamping device and pile body contact area greatly, will not damage pile body with
And produce slippage during pile pulling.Make stake with the soil body point using being arranged under the shaking force of clamping device top jarring machine 7 is acted on
From, recycle crane or excavator to do lifting traction, stake is smoothly extracted.
Only presently preferred embodiments of the present invention above, can not limit the interest field of the present invention with this certainly,
Therefore the equivalence changes made according to scope of the present invention patent, still belong to protection scope of the present invention.
