Abstract
The utility model discloses a double oil cylinder acting type square pile clamping device used for a hydraulic static pile press. The device comprises a pile clamping box, pile clamping jaws used for contacting four surfaces of a square pile and eight pile clamping oil cylinders, wherein the pile clamping oil cylinders are fixed on the pile clamping box, and each pile clamping jaw is connected with two pile clamping oil cylinders. The double oil cylinder acting type square pile clamping device used for a hydraulic static pile press has the advantages of simple and compact structure, low cost, simple assembly, wide application range and good clamping effect.
Description
Technical field
The utility model is mainly concerned with the piling machinery field, refers in particular to a kind of two oil cylinders action type side pile holder that is used for hydraulic static pile pressing machine and holds device.
Background technology
At present, hydraulic static pile pressing machine has obtained extensive utilization in the construction of prefabricated piles field, and the work of static pile press is by pile clamping box preformed pile to be clamped, and adopts hydraulic jack to drive pile clamping box and makes preformed pile sink to ground.Two kinds of the preformed pile side of mainly containing stake and pile tubes, hydraulic static piling often by change pile-clamp in its pile clamping box make its can the side of folder again can the clamp stake.Because there is deviation from circular from pile tube; and pile tube is a hollow section; the tubing string that has still is a thin-walled; for the Pile holding mechanism that makes the hydraulic pressure Static pressure pile driver is protected the pile tube that is pressed from both sides better; now very mostly adopted the mode of multiple spot folder stake; this mode is that the pile-clamp piece number in the pile clamping box is increased, and generally adopts 16 pile-clamps.As shown in Figure 2, pile clamping box is divided into upper and lower two-layer, 8 every layer folder stake oil cylinders 1, and totally 16 press from both sides stake oil cylinders 1, and each folder stake oil cylinder 1 links to each other with a pile-clamp 4, is used for driving pile-clamp 4 motions pile tube 6 is carried out clamping.As shown in Figure 3, when using above-mentioned clamping case to come the stake 7 of clamping side, the pile-clamp 4 of each side's stake 7 can only connect a folder stake oil cylinder 1, therefore have only 8 folder stake oil cylinders 1 can participate in work, and other 8 folder stake 1 free time of oil cylinder are not only caused waste, and pile locking force deficiency often.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provides a kind of simple and compact for structure, with low cost, assembling two oil cylinders action type side pile holder that is used for hydraulic static pile pressing machine simple, applied widely, good clamping effect to hold device.
For solving the problems of the technologies described above, the utility model by the following technical solutions.
A kind of two oil cylinders action type side pile holder that is used for hydraulic static pile pressing machine is held device, comprise pile clamping box, be used for and four contacted pile-clamps of face of side's stake and eight folder stake oil cylinders, described folder stake oil cylinder is fixed on the pile clamping box, it is characterized in that: described each pile-clamp links to each other with two folder stake oil cylinders.
As further improvement of the utility model:
Be provided with contiguous block between described each folder stake oil cylinder and the pile-clamp, an end of described contiguous block is fixed on the piston rod of folder stake oil cylinder, and the other end contacts cooperation with pile-clamp.
Described pile-clamp is provided with one and connects spring, and an end of described connection spring is fixed on the pile clamping box.
Compared with prior art, advantage of the present utility model just is:
The utility model is used for two oil cylinders action type side pile holder of hydraulic static pile pressing machine and holds device, have simple and compact for structure, with low cost, advantages such as assembling is simple, applied widely, good clamping effect, wherein can act on two folder stake oil cylinders simultaneously on every pile-clamp, improve the utilization rate of folder stake oil cylinder, and strengthened pile locking force.Adopting spring to form between pile-clamp and the pile clamping box flexibly connects, both solved the nonsynchronous problem of piling oil cylinder, and can adjust pile-clamp again automatically itself and stake surface, side are attached fully, and made stake stressed evenly, avoid causing bad stake or broken stake, simultaneously pile-clamp is resetted.

The specific embodiment
Below with reference to specific embodiment and Figure of description the utility model is described in further details.
As shown in Figure 1, the utility model is used for two oil cylinders action type side pile holder of hydraulic static pile pressing machine and holds device, comprise pile clamping box 8, be used for and 7 four contacted pile-clamps 4 of face of side's stake and eight folder stake oil cylinders 1, folder stake oil cylinder 1 is fixed on the pile clamping box 8, and each pile-clamp 4 links to each other with two folder stake oil cylinders 1.Be provided with contiguous block 2 between each folder stake oil cylinder 1 and the pile-clamp 4, an end of contiguous block 2 is fixed on the piston rod of folder stake oil cylinder 1 by attachment screw 3, and the other end contacts cooperation with pile-clamp 4.Pile-clamp 4 is provided with one and connects spring 5, and an end that connects spring 5 is fixed on the pile clamping box 8.Pile-clamp 4 is because the effect of connection spring 5 simultaneously is attached on the face that contacts with contiguous block 2, and another side then is a folder stake face.When on acting on a pile-clamp 4 two folder stake oil cylinders 1 were asynchronous, pile-clamp 4 also can the self adaptation oscillation adjustment.Equally, pile-clamp 4 also can be adjusted automatically according to the shape on 7 surface, side during the folder stake, and the folder stake face of pile-clamp 4 is fitted fully with stake 7 surfaces, side, and the side's of making stake 7 is stressed even.The side's of unclamping stake 7 o'clock, pile-clamp 4 resets under the tension that connects spring 5 certainly.
During use,, will promote piston rod and advance when pressure oil enters the rodless cavity that presss from both sides stake oil cylinder 1.Piston rod drive contiguous block 2 and pile-clamp 4 advance and realize the folder stake.On acting on a pile-clamp 4 two folder stake oil cylinders 1 connect spring 5 when asynchronous and are stretched, pile-clamp 4 around with is connected fixed point that spring 5 connects with the space scope of contiguous block 2 in rotate adjustment.The folder stake face of pile-clamp 4 is when side stake surface contact substantially, and pile-clamp 4 can be adjusted automatically up to a folder face and a square surface according to the shape on stake surface and fit fully under folder stake oil cylinder 1 and the effect that is connected spring 5.When pressure oil enters folder stake oil cylinder 1 rod chamber, promote piston rod and retreat, piston rod drives contiguous block 2 and pile-clamp 4 retreats the stake of realization pine, and pile-clamp 4 returns to initial position under the elastic force effect that connects spring 5 simultaneously.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
