Description
Technical field
The invention belongs to constructional engineering machinery field, relate to a kind of piling machinery, be specifically related to a kind of piling oil cylinder of static pile press.
Background technique
Pile driver conventional in construction is divided into hammering type and static pressure type substantially, hammering type pile driver impacts pile crown by pile monkey, make stake under the effect of impact force in injection soil, noise be large because existing, the shortcoming such as waste air, befouling environment, be progressively eliminated use.Now, the comparatively normal pile driver used is Static pressure pile driver, it adopts machinery or hydraulic way to produce static pressure, stake is made to be pushed down into stratum to desired depth in continuously compressive pressure effect, be generally used for Soft Soil Layer piling, compared with hammering type stake machine, have noise low, vibrate little, pollution-free, efficiency advantages of higher.The construction technology process utilizing Static pressure pile driver to implement static pressure pile-sinking is roughly divided into: measurement and positioning-pile-forming machine perching-hang stake, pitching pile-pile body centering straightening-static pressure pile-sinking-pile extension-static pressure pile-sinking-pile follower again-termination piling-cutting pile crown.
The Static pressure pile driver used at present is generally hydraulic type Static pressure pile driver.The part compositions such as hydraulic type Static pressure pile driver mainly comprises pile frame, hangs a hoist, pile clamping box, piling oil cylinder, electrical equipment, main hydraulic oil container and secondary hydraulic oil container.Pile frame is the supporting portion of complete machine, and main platform, guide table, column and lower running chassis are housed.Hang a hoist and be loaded on column top, in place for hanging stake.During piling operation, pile clamping box clamping pile crown, then push pile chuck by a pair piling oil cylinder, stake is sunk.Electrical equipment is used for Host actuating pump running, machine-walking.Wherein, pile frame, pile clamping box and piling oil cylinder form the piling main body of Static pressure pile driver.
The piling oil cylinder of traditional static pile press is two oilholes, i.e. rod chamber oilhole, rodless cavity oilhole.During specific works, promote pile clamping box backhaul in rod chamber oil-feed, when rodless cavity carries out oil extraction, the oilhole oil extraction of existing piling oil cylinder can produce larger back pressure, causes pile clamping box lifting speed slow, thus makes the time of piling long.And the pipeline of fuel tank and interface are standard or General Construction, be convenient to later period maintenance like this; Meanwhile, need the size considering pipeline during design oil circuit, pipeline is thicker, is more not easy bending, takes up room larger.Meanwhile, existing hydraulic jack does not arrange effective assembly and boom hoisting, is not easy to install and transhipment, and the sealability of oil cylinder is bad, and these all have much room for improvement.

Further, the side of described support ring (3) is provided with cross section is that the annular seal ring of convex contacts with the inwall of cylinder barrel (1).
Further, the end face of described cover plate (5) is provided with suspension hook (6), piston rod (2) end of described cylinder barrel (1) is provided with mounting flange (8).
Further, two hydraulic fluid port B(10 of the side of described cover plate (5)) radially layout pitch 30 °-50 °.
Beneficial effect of the present invention: 1, effectively can reduce back pressure when piling oil cylinder rodless cavity carries out oil extraction, promotes the rate of climb of pile clamping box, saves the return interval of piling, improve the useful effect efficiency of pile pressing machine, effectively shorten construction period.
2, the oil drainage hole of many rodless cavities, return oil pressure is reduced, and oil return is more unobstructed.
3, simple and reliable for structure, be provided with effective assembly and boom hoisting, be convenient to install and transhipment, and the sealability of oil cylinder improved by the annular seal ring applying convex.

Embodiment
In order to make those skilled in the art understand technological scheme of the present invention better, describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
As shown in Figure 1-2, annexation of the present invention is: it comprises the support ring 3 of cylinder barrel 1 and the setting of cylinder barrel 1 inwall, and the piston rod 2 that the inside center being in cylinder barrel 1 is connected with support ring 4; The annular guide sleeve 7 that the front end of piston rod 2 is arranged by cylinder body 1 inside forms rod chamber with the sealing of cylinder body 1, and the end of piston rod 2 forms rodless cavity by cover plate 5 and the end seal of cylinder barrel 1; In the side of cover plate 5, be circumferentially provided with two hydraulic fluid port B10, the side, front end of described cylinder barrel 1 is provided with a hydraulic fluid port A9.
Preferably, the side of described support ring 3 is provided with cross section is that the annular seal ring of convex contacts with the inwall of cylinder barrel 1.
Preferably, the end face of described cover plate 5 is provided with suspension hook 6, piston rod 2 end of described cylinder barrel 1 is provided with mounting flange 8.So, be more conducive to the transhipment of oil cylinder and fix.
Preferably, two hydraulic fluid port B10 of the side of described cover plate 5 radially layout pitch 30 °-50 °.So, be more conducive to the oil return of hydraulic oil, reduce the generation of back pressure, save the idle running time.
Fig. 3 is the oil circuit connection diagram of the static pile press applying piling oil cylinder of the present invention.When promoting multi-way valve 15 piling, the hydraulic fluid port B oil-feed of piling oil cylinder 11, hydraulic fluid port A oil extraction, hydraulic fluid port A hydraulic oil is low pressure this moment, and hydraulic control fuel outlet valve 13 is in closed condition, and now piling oil cylinder 11 down promotes pile clamping box 12 piling;
When promoting multi-way valve 15 and promoting pile clamping box rising, hydraulic fluid port A oil-feed, now hydraulic fluid port A is high pressure liquid force feed, and hydraulic control fuel outlet valve 13 is opened, and two hydraulic fluid port B oil returns simultaneously, rodless cavity back pressure reduces, and oil return is unobstructed, thus shortens the time of piling oil cylinder backhaul.From construction, namely piling oil cylinder improving clamping vanning backhaul is idle stroke for flogging a dead horse, and so the shorter efficiency of construction of empty stroke time is higher.Therefore, the setting of two hydraulic fluid port B, effectively can solve the problem of idle stroke and return oil pressure, provide working efficiency.
The present invention effectively can reduce back pressure when piling oil cylinder rodless cavity carries out oil extraction, promotes the rate of climb of pile clamping box, saves the return interval of piling, improve the useful effect efficiency of pile pressing machine, effectively shorten construction period.The oil drainage hole of many rodless cavities, return oil pressure is reduced, and oil return is more unobstructed.Simple and reliable for structure, be provided with effective assembly and boom hoisting, be convenient to install and transhipment, and the sealability of oil cylinder improved by the annular seal ring applying convex.
Apply specific case herein to set forth principle of the present invention and mode of execution, the explanation of above example just understands method of the present invention and core concept thereof for helping.The above is only the preferred embodiment of the present invention, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the premise without departing from the principles of the invention, some improvement, retouching or change can also be made, also above-mentioned technical characteristics can be combined by rights; These improve retouching, change or combination, or the design of invention and technological scheme are directly applied to other occasion without improving, and all should be considered as protection scope of the present invention.
