Description
Technical field
The present invention relates to a kind of hydraulic static pile pressing machine, especially relate to a kind of down-the-hole impact type hydraulic static pile pressing machine.
Background technology
At present, the preformed pile foundation piling mainly contains following dual mode: the one, impact the preformed pile top with diesel hammer, and squeeze into pile in the ground to preformed pile; Another kind is to use hydraulic static pile pressing machine, and preformed pile is pressed into pile in the ground.The diesel hammer impact force is big, and penetration power is strong, and transition is flexible, but construction noise is big, and oil smoke is many, and is seriously polluted, the fragile stake of impact force, and especially for the bigger stake of bearing capacity, construction quality is difficult to control, receives constructor's influence bigger.The hydraulic static pile pressing machine construction is shockproof, and noise is less, and is energy-efficient, and pile quality is high; But machines cumbersome requires high to the construction plant; If there is closely knit hard formation in the stratum, particularly thick grit layer, because of penetrating resistance is big, the stake end is difficult to penetrate, and the scope of application is restricted.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the present invention provides a kind of down-the-hole impact type hydraulic static pile pressing machine applied widely.
Technical scheme of the present invention is: it comprises fuselage platform, elevating mechanism, vertical shift mechanism and transverse-moving mechanism, and the fuselage platform links to each other with vertical shift mechanism, transverse-moving mechanism through elevating mechanism, and the fuselage platform is provided with driver's cabin, crane, piling platform, moving counterweight iron, electric-control system and hydraulic control system; The piling platform is provided with the piling oil cylinder, and the tailpiece of the piston rod of piling oil cylinder is connected with pile clamping box, it is characterized in that; Also be provided with pylon on the said fuselage platform, the pylon top is supported through revolution and is connected with tower head, and tower head is provided with hoist engine; The wire rope of hoist engine links to each other with block stamp; Also be provided with between the same axis of block stamp and pile clamping box, pylon and tower head and be connected oil cylinder, the cylinder barrel and the pylon that connect oil cylinder are hinged; The piston rod and the tower head that connect oil cylinder are hinged, and the connection oil cylinder links to each other with hydraulic control system on being located at the fuselage platform through oil pipe.
When the present invention's down-the-hole impact type hydraulic static pile pressing machine was used for the preformed pile foundation piling, it was conical shoe that a bottom need be set in the preformed pile bottom.During work, at first preformed pile is winched to the stake position, hold preformed pile tightly through pile clamping box, through piling oil cylinder static pressure pile-sinking, it is descending to promote pile clamping box, is pressed into ground to preformed pile.When preformed pile is sink to the difficult degree of depth,, make the center of block stamp, over against the centre bore of preformed pile over against pile clamping box through the rotation tower head; Control freely transferring and promoting of block stamp through hoist engine, when block stamp falls, be similar to freely falling body, block stamp is aimed at shoe and is impacted in the centre bore of preformed pile; Produce huge impact power, overcome the ground resistance, the descending segment distance of shoe; Simultaneously, under the static pressure effect that when the piling oil cylinder promotes pile clamping box, produces, it is descending that preformed pile is followed shoe.
Be pressed into and impact combines through hydraulic static, can preformed pile be steadily sunk down into projected depth.At this moment, if need pile extension, then block stamp is mentioned, through the control connection oil cylinder through hoist engine; Make tower head drive block stamp and turn round an angle, abdicate the stake position, second preformed pile winched to the stake position, pile clamping box is held second preformed pile tightly; And aim at first preformed pile having sunk, and the beginning pile extension, block stamp is back to working position, even block stamp is over against the center of pile clamping box; Over against the centre bore of preformed pile, block stamp continue to impact, and is same, is pressed into and impact combines through hydraulic static; Second preformed pile is pressed into, so repeatedly, until reaching design elevation.
Advantage of the present invention is: impact force directly acts on shoe, and shock wave is not through the preformed pile transmission, and is harmless to preformed pile; Not loss when transmitting energy, it is big to impact the explosive force that produces, and can overcome the resistance of preformed pile stake end, and the bearing capacity of preformed pile is high; Carry out in the preformed pile centre bore because of impacting, noise is little, and is pollution-free.End resistance is mainly overcome by impact force, and pile driving pressure can correspondingly reduce, and the existing hydraulic static pile pressing machine of complete machine weight ratio is light; Use the present invention, the piling quality is high, can easily penetrate closely knit hard formation, and the scope of application is wider.
Description of drawings

Fig. 2 is pylon and local enlarged diagram of being connected of tower head.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
With reference to accompanying drawing; Present embodiment comprises fuselage platform 1, elevating mechanism 2, vertical shift mechanism 4 and transverse-moving mechanism 6; Fuselage platform 1 links to each other with vertical shift mechanism 4, transverse-moving mechanism 6 through elevating mechanism 2, and fuselage platform 1 is provided with driver's cabin 3, crane 16, piling platform 5, moving counterweight iron 17, electric-control system (not shown) and hydraulic control system (not shown), and piling platform 5 is provided with piling oil cylinder 19; The tailpiece of the piston rod of piling oil cylinder 19 is connected with pile clamping box 18; Piling oil cylinder 19 can drive pile clamping box 18 in 5 slips of piling platform, also is provided with pylon 7 on the said fuselage platform 11, and pylon 7 tops are supported 15 through revolution and are connected with tower head 13.Tower head 13 is provided with hoist engine 8, and the wire rope of hoist engine 8 links to each other with block stamp 10, block stamp 10 and pile clamping box 18 same axis; Also be provided with between pylon 7 and the tower head 13 and be connected oil cylinder 14; The cylinder barrel and the pylon 7 that connect oil cylinder 14 are hinged, and the piston rod and the tower head 13 that connect oil cylinder 14 are hinged, and connection oil cylinder 14 links to each other with hydraulic control system (not shown) on being located at fuselage platform 1 through oil pipe 20; Operation hydraulic control system respective valve piece, but control connection oil cylinder 14 promotes tower head 13 with respect to pylon 7 revolutions.
When this kind down-the-hole impact type hydraulic static pile pressing machine was used for the preformed pile foundation piling, it was conical shoe 11 that preformed pile 9 bottoms should be provided with a bottom.During work, at first preformed pile is winched to the stake position, hold preformed pile tightly through pile clamping box, through piling oil cylinder 19 static pressure pile-sinkings, it is descending to promote pile clamping box 18, is pressed into ground 12 to preformed pile 9.When preformed pile 9 is sink to the difficult degree of depth,, make the center of block stamp over against pile clamping box through the rotation tower head; Over against the centre bore of preformed pile, control freely transferring and promoting of block stamps 10 through hoist engine 8, when block stamp 10 falls; Be similar to freely falling body, block stamp 10 is aimed at shoe 11 and is impacted in the centre bore of preformed pile 9, produce huge impact power; Overcome ground 12 resistances, shoe 11 descending segment distances, simultaneously; Under the static pressure effect that when piling oil cylinder 19 promotes pile clamping box 18, produces, it is descending that preformed pile 9 is followed shoe 11.
