Abstract
The utility model discloses a hydraulic pipe-drawing device, relating to construction machinery, composed of clamping devices and hydraulic oil cylinders. The clamping devices are formed by the fixing connection of lever cross beams and bearing bases, and each bearing base is hinged with a semi-circular clamping tile. The clamping devices are hinged with each other, the outer end side of each clamping device is connected with the hydraulic oil cylinder, and the cylinder body of the oil cylinder is fixed on a working table. The utility model realizes the clamping operation and the lifting operation simultaneously, the structure is simple and the operation is convenient. The hydraulic pipe-drawing device is particularly suitable for the pile-foundation construction of high-tonnage pipe-drawing force.
Description
The utility model relates to a kind of building machinery, and the stake pipe static(al) that is specially adapted to the building foundation filling pile construction is pulled out.
At present, in the building foundation filling pile construction, its pipe pull out way normally: with a pair of movable and fixed pulley group that is positioned at the pile driving frame column back side of hoist engine traction, be two scale wire rope on the follow-up pulley group, lead down from the column front side through the column top pulleys, lie on the pipe.Start hoist engine, after assembly pulley increases multiplying power, realize tube drawing from the column top by the scale steel wire.Also have from the column top directly by movable and fixed pulley group pile pulling pipe.The size of pulling out villous themeda power is by the tractive force of hoist engine and the multiplying power decision of moving fixed pulley group.This way structure is loaded down with trivial details, and because the working condition lower stress is unreasonable, very high to the strength and stiffness requirement of pile driving frame (especially staking out part), cause physical dimension to dote on greatly the cost height; Stability and safety are all relatively poor.Especially to the pile driving frame of high tonnage tube drawing power (more than 100 ton forces), almost can't realize tube drawing with said method.
The purpose of this utility model is to provide a kind of hydraulic pipe drawing device, can simplify the structure of pile driving frame, can make pile driving frame reach the performance requirement of high tonnage tube drawing power again.
In order to achieve the above object, this is suitable for novel a kind of hydraulic pipe drawing device is to be hinged in twos between the clamper, all is associated with hydraulic jack on every clamper.Hydraulic jack promotes clamper separately, each clamper is closed up and upward act synchronously.
After adopting this structure, hinged in twos clamper is under action of gravity, and stake pipe naturally reclines.The make progress jacking and directly act on clamper of primer fluid compressing cylinder, piston rod.The stake pipe is tightly embraced in clamper performance leverage; Meanwhile, along with the progressively jacking of piston rod, the stake pipe finishes until the piston rod stroke just along with the clamper that hugs pulls out synchronously; Subsequently, piston rod backhaul and to drive clamper descending, clamper unclamps the stake pipe automatically simultaneously, and falls to resetting with piston rod; And so forth, all transfer to, thereby realized that clamping, jacking carry out synchronously until column jecket, simple in structure, easy to operate, greatly simplified the pile driving frame structure, be particularly useful for the pile foundation construction of high tonnage tube drawing power.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is a specific embodiments structural representation of a kind of hydraulic pipe drawing device of the utility model.
Hydraulic pipe drawing device shown in Figure 1 is formed by bearing pin 5 and the clamper 1 that is hinged by two, at the outer distolateral hydraulic jack 9 that all is connected with of every clamper 1.Clamper 1 is by lever crossbeam 3 and supporting base 2 affixed forming, and clamper 1 is hinged by lever crossbeam 3, can make clamper 1 obtain rigidity and manufacturability preferably like this; Simultaneously in order to increase the contact area of clamper 1 and stake pipe 4, and reduce the damage of 1 pair of stake pipe 4 of clamper, on the supporting base 2 of clamper 1, be connected with half garden clevis watts 6, change the folder watts 6 of all size, can adapt to the stake pipe 4 of different size by bearing pin 7; And can also be packed with folder watt lining in it on the cambered surface of garden,, prolong the folder watt life-span with anti-pinch watt rapid wear.Owing to adorned folder watts 6 on the clamper 1, when stake pipe 4 tilted, folder watts 6 can be made compliance around bearing pin 7 and rotate, in order to operate as normal.Hydraulic jack 9 is by cylinder body 10, piston rod 11, advances the general Hydraulic Elements that back pressure power oil pipe 12 is formed, and its piston rod 11 and 3 outer distolateral linking to each other of lever crossbeam, its cylinder body 10 is installed on the workbench 8, and is connected with and leads to the advancing of hydraulic power station, time hydraulic oil pipe 12.During work, stake pipe 4 inserts between the folder watts 6, under the deadweight effect, folder watts 6 villous themeda 4 that reclines naturally is started oil cylinder 9, piston rod 11 upwards jackings, clamper 1 is exerted pressure to folder watts 6 around swivel pin 5 rotations, makes folder watts 6 produce chucking powers and tightly embraces stake pipe 4, along with the progressively jacking of piston rod 11, pull out on stake pipe 4 and clamper 1 are also synchronous, finish until piston rod 11 strokes; Cold bar 11 backhauls of living, clamper 1 are around hinging pin shaft 5 backspins, and the chucking power of folder watts 6 disappears automatically and unclamps stake pipe 4, and clamper 1 falls to resetting with piston rod 11, and stake pipe 4 does not descend, and so repeatedly, all extracts ground until stake pipe 4.
