The utility model is an automatic aligning pile clamping device for hydraulic static pile press machine, which has simple and compact structure and low cost, and can perform adaptive aligning.
Description
Technical field
The utility model is mainly concerned with the piling machinery field, but refers in particular to a kind of automatic aligning folder stake device that is used for hydraulic static pile pressing machine.
Background technology
At building field, the work of Static pressure pile driver is by Pile holding mechanism (pile clamping box) concrete precast pile to be clamped, adopting hydraulic jack to drive Pile holding mechanism makes preformed pile sink to ground, the ideal operation state of Pile holding mechanism is that the folder stake surface of pile-clamp contacts fully with the preformed pile surface, makes pile body stressed evenly.Yet reasons such as stake machine fuselage tilts owing to existing in real work, the foozle of the error in geometrical form of preformed pile, stake machine Pile holding mechanism and condition of work are abominable make that appearance point, line contact between pile-clamp and the preformed pile, preformed pile surface local contact stress is increased, the preformed pile discontinuity, cause brokenly phenomenons such as stake, broken pile, have a strong impact on piling quality, piling efficient and economic benefit.
In the prior art, the common jaw of Static pressure pile driver mainly contains three kinds with the connected mode of pressing from both sides the stake oil cylinder: first kind is that the end face and the jaw that will press from both sides stake oil cylinder piston bar is rigidly connected with bolt; Second kind is to be provided with the sphere that falls at the end face that presss from both sides stake oil cylinder piston bar, and pile-clamp has the sphere of protrusion with a folder stake oil cylinder piston bar junction, and is connected to form hinge by bolt between the two; The third is the folder stake machinery that drives jaw by two pairs of wedges.
Occur that a stake machine fuselage tilts or the own shape of preformed pile when having too situation such as mistake when when stake folder, above-mentioned first kind of structure can not be done any adjusting makes jaw contact fully with preformed pile.In above-mentioned second kind of structure, though can do the adjustment of all directions between folder stake oil cylinder piston bar and the pile-clamp, but because the jaw spherical surface is to be connected with bolt with oil cylinder piston bar sphere, each adjustment all can produce distortion to bolt, thereby it is tired that bolt is produced, damage easily, need often to change bolt.Above-mentioned the third structure also can be done suitable adjusting, but in real work since voussoir between frequent bonding friction, make and produce wearing and tearing between the voussoir contact surface, when causing in the piling process piling stroke to finish Pile holding mechanism need to unclamp preformed pile, voussoir can not normally break away from, and forms " stuck " phenomenon.
The utility model content
The technical problems to be solved in the utility model just is: at the technical problem of prior art existence, but the utility model provides a kind of automatic aligning that is used for hydraulic static pile pressing machine simple and compact for structure, easy for installation, with low cost, applied widely, that can carry out the self adaptation aligning to press from both sides a stake device.
For solving the problems of the technologies described above, the utility model by the following technical solutions.
But a kind of automatic aligning folder stake device that is used for hydraulic static pile pressing machine, it comprises pile-clamp and folder stake oil cylinder, it is characterized in that: be provided with the jaw ball cup between described pile-clamp and the folder stake oil cylinder, the middle part of described jaw ball cup links to each other with folder stake oil cylinder by first bolt, be provided with in the gap of leaving between described jaw ball cup and the folder stake oil cylinder and be connected pressing plate, described connection pressing plate links to each other with pile-clamp by second bolt.
As further improvement of the utility model:
Be provided with back-moving spring between described connection pressing plate and the jaw ball cup.
Described back-moving spring is installed on and connects in the installing hole of offering on pressing plate and the jaw ball cup.
Described folder stake oil cylinder is fixed on the pile clamping box.
Compared with prior art, advantage of the present utility model just is:
But the utility model is used for the automatic aligning folder stake device of hydraulic static pile pressing machine, simple and compact for structure, make simple, easy for installation, not only applicable to the clamp stake but also applicable to the stake of folder side, can effectively avoid brokenly the phenomenon of stake, bad stake during the folder stake, can bear big pressure, be applicable to all kinds of hydraulic static pile pressing machines.Pile-clamp of the present utility model be connected pressing plate and constitute whole and form ball pivot with the jaw ball cup, when pressing from both sides, if there is the error in geometrical form of machine error such as pile clamping box, pile-clamp, folder stake oil cylinder and stake, also can both carry out the self adaptation correction, be fitted fully in the folder stake face of every pile-clamp and stake surface by the free beat of every pile-clamp.Simultaneously, connect establish between pressing plate and the jaw ball cup back-moving spring make whole adjustment process be flexible, can recover automatically, avoided when regulating, occurring bad phenomenon such as mechanical wear, generation fatigue.

The specific embodiment
Below with reference to specific embodiment and Figure of description the utility model is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, but the automatic aligning folder stake device that is used for hydraulic static pile pressing machine of the present utility model, it comprises pile-clamp 2 and folder stake oil cylinder 6, folder stake oil cylinder 6 is fixed on the pile clamping box 1, be provided with jaw ball cup 3 between pile-clamp 2 and the folder stake oil cylinder 6, the middle part of jaw ball cup 3 links to each other by the piston rod of first bolt 8 with folder stake oil cylinder 6, be provided with in the gap of leaving between the circumference place of jaw ball cup 3 and the folder stake oil cylinder 6 and be connected pressing plate 5, connecting pressing plate 5 links to each other with pile-clamp 2 by second bolt 7, connect pressing plate 5 like this and can in interstice coverage, do the action of universal coupling formula around jaw ball cup 3 with pile-clamp 2, form flexible adaptive regulating mechanism, finish the self adaptation aligning.As preferred embodiment, connect in the present embodiment between pressing plate 5 and the jaw ball cup 3 and be provided with back-moving spring 4, back-moving spring 4 is installed on and connects in the installing hole of offering on pressing plate 5 and the jaw ball cup 3.
In use, enter the rodless cavity of folder stake oil cylinder 6 when pressure oil after, will promote piston rod and advance.The piston rod drive jaw ball cup 3 of folder stake oil cylinder 6 and pile-clamp 2 advance and realize the folder stake, when the center line of preformed pile 9 during not with pile clamping box 1 desired center line parallel, pile-clamp 2 can be regulated automatically with back-moving spring 4, thereby the folder stake face of pile-clamp 2 is contacted fully with the surface of preformed pile.When pressure oil enters the rod chamber of folder stake oil cylinder 6, will drive piston rod and retreat.The piston rod of folder stake oil cylinder 6 drives jaw ball cup 3 and pile-clamp 2 retreats the stake of realization pine, and pile-clamp 2 recovers initial position under the elastic force effect of back-moving spring 4 simultaneously, makes the folder stake face center line of pile-clamp 2 parallel with the center line of pile clamping box 1.
