In one embodiment of the present of invention, the working principle of the invention:
This pile-drawing machine can pile pulling stake diameter range≤1000mm, suitable for the pile body of various shape and material, construction cost is low,
Simple process, convenient for operation, speed of application is fast, simple and practical.The present invention is a kind of hydraulic jaw type clamping mechanical pile pulling device, packet
Include: hydraulic tongs clamping device, including hydraulically operated fixture are realized and the stake in clamping device are implemented to hold tightly or be unclamped;Changeable clamp,
It is installed on hydraulic clamp, matched clamp can be replaced according to piles with different diameter and pile-type, make to generate between stake and pile pulling device and rub
It wipes power and is greater than the soil body to the frictional force of stake.Shaking device generates vibration using motor, carries out drawing to the stake for being embedded in underground, makes
Stake generates loosening;Hydraulic lift.The open or close tong arm that the present invention can be convenient, so that clamping device be made to be tightly attached to stake
Surface will be squeezed between the stake on ground and the soil body using shaking device and be loosened, and reduce frictional force, it is ensured that pile body is complete during pile pulling
It is good, while above mentioning using site machinery (truck crane or excavator) and extracting stake;The device is not limited by geographic, and can be incited somebody to action
The extraction of the pile bodies such as plane, the circle stake in slope surface, square pile is squeezed into, does not destroy pile body, the present invention can utmostly protect original stake
Body, the stake of extraction can secondary use, saved investment.
The pile pulling process that the present invention takes is as follows:
1, corresponding fixture is selected (to pull out round 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 rectangular fixture, and rectangular and circular clamp side length and diameter are consistent with institute's pile pulling specification, because of live stake type
And specification is almost the same, therefore floating holder only need substantially one to two set, will not frequently replace), by fixture by bolt with it is hydraulic
The connection of jaw type clamping device is integral.
2, it is connect by pile-drawing machine top two sides lifting lug 8 with crane using wirerope or logical pile-drawing machine top center
Attachment device connect (tie point of top center can horizontal rotation angle) with excavator swing arm.
3, clamping clip is opened by synchronous electric hydraulic lifting jack 2, opening degree extremely can be from pile body side or top by stake
Being inserted in 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.
4, jarring machine 7 at the top of pile-drawing machine is started, shaking force is transmitted to clamping machine by the supporting leg that is rigidly connected by jarring machine 7
Structure, then it is transmitted to pile body, increase stake and soil body gap using vibration, frictional force reduces, then passes through crane or excavator for stake
Stake is proposed the soil body by lift cramping arrangement.
5, the stake of extraction is still clamped to be placed in crane or digging machine and piles up position, utilize 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.
It 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 folder
Tight device opening degree is big, and pile body can accurately be clamped by being not necessarily to precisely operate during clip pile, for being not easy accurately to see in water etc.
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
Shaking force is transmitted to clamping device by rigid leg 6, then passes to pile body by portion's jarring machine 7, is made between stake and the soil body using vibration
Gap increases, and frictional force reduces, then stake is lifted out the soil body by crane or excavator;The required mating lifting means scope of application
Extensively, it can be connect with the existing mechanical equipments such as crane or excavator in scene, as lifting means, connection type is flexible, hangs
Vehicle is connected using wirerope and the suspension of equipment two sides lifting lug 8, and excavator is using swing arm and top center roller pin axis connection, connection
Mode is simple and fast, securely and reliably.The present apparatus is the formula of pulling out of hanging, and clamping device is open-close type hydraulic clamping device, by clamping device
Opened using hydraulic system, directly clamping one lower portion of pile crown, clamping device and pile body contact area are big, will not damage pile body with
And generate slippage during pile pulling.Make stake and the soil body point under acting on using the shaking force that jarring machine 7 at the top of clamping device is arranged in
From recycling crane or excavator do promotion traction, extract stake smoothly.
Above is only presently preferred embodiments of the present invention, and of course, the scope of rights of the present invention cannot be limited by this,
Therefore according to equivalence changes made by scope of the present invention patent, still belong to protection scope of the present invention.
