Abstract
The utility model discloses a hydraulic vibrating pile hammer. The hydraulic vibratory pile hammer comprises a pull rope, a vibration absorber, a vibration exciter, a clamp, a pile body, a gear box and a hydraulic station, wherein the pile body is connected with the gear box through the clamp; the gear box is connected with the vibration exciter; the vibration exciter is connected with the hydraulic station through a hydraulic rubber pipe; an eccentric device is arranged inside the vibration exciter; the vibration exciter is connected with the vibration absorber through an elastic device; and the pull rope is connected with the vibration absorber. Through the hydraulic vibrating pile hammer, a periodical vibration exciting force generated by the vibration exciter vibrates the pile body, so that soil around the pile body is liquefied; therefore, the friction between the soil and the pile body is greatly reduced and the pile body can sink into the soil under the action of self weight; and the hydraulic vibrating pile hammer is simple in structure and good in using effect.
Description
Technical field
The utility model relates to the building machinery field, is specifically related to a kind of hydraulic vibrohammer that in clay, carries out preformed pile or pile sinking.
Background technology
Vibrohammer belongs to the pile foundation construction machinery that uses in the construction work, is used for the construction of cast-in-place concrete pile.With pile frame supporting after, can sink cast-in-place concrete pile, concrete pedestal pile (big head of garlic stake), lime pile, sand pile, broken stone pile; After mixing pile chuck, can sink pulling concrete preformed pile and all kinds of piling bar.It is the ideal equipment of foundation constructions such as highway, bridge, airport, building.Vibrohammer also can be used as mechanical piling such as vibrator sunk pile machine, board-plugging device with hammer in addition.
In clay, preformed pile and pipe are carried out pile vibrosinking can practice thrift construction cost greatly.From operation, only need usually to impact 10 of pile sinking hammer, but at some in particular cases, vibrohammer possibly lose efficacy, and stake is sunk.
The utility model content
The utility model has overcome the deficiency of prior art, and a kind of simple in structure, effective hydraulic vibrohammer of driving piles is provided.
For solving above-mentioned technical problem, the utility model adopts following technical scheme:
A kind of hydraulic vibrohammer; Comprise stay cord, shock absorber, vibrator, clamp, pile body, gear-box and Hydraulic Station, said pile body is connected with gear-box through clamp, and said gear-box is connected with vibrator; Said vibrator is connected with Hydraulic Station through hydralic hose; Be provided with eccentric in the said vibrator, said vibrator is connected with shock absorber through elastic device, and said stay cord is connected with shock absorber.
In order to realize the utility model better, improvement technical scheme further is:
As preferably, above-mentioned elastic device is a spring.
The utility model can also for:
As preferably, above-mentioned eccentric is two eccentric massblocks.
Compared with prior art, one of beneficial effect of the utility model is:
In the utility model technical scheme, the periodicity exciting force that vibrator produces makes pile body produce vibration, thereby makes the soil liquefaction of pile body periphery, and soil reduces the frictional force of pile body greatly like this, and pile body just can sink to soil under the action of gravity of self;
This apparatus structure is simple, and result of use is good.
Description of drawings
Fig. 1 is the composition structural representation of the utility model;
Fig. 2 is the structural representation of the utility model eccentric.
Wherein, the pairing name of the Reference numeral in the accompanying drawing is called:
The 1-stay cord, 2-shock absorber, 3-spring, 4-vibrator, 5-clamp, 6-pile body, 7-hydralic hose, 8-Hydraulic Station, 9-eccentric massblock, 10-gear-box.
The specific embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the embodiment of the utility model is not limited thereto.
Like Fig. 1, shown in Figure 2, a kind of hydraulic vibrohammer comprises stay cord 1, shock absorber 2, vibrator 4, clamp 5, pile body 6, gear-box 10 and Hydraulic Station 8; Said pile body 6 is connected with gear-box 10 through clamp 5; Said gear-box 10 is connected with vibrator 4, and said vibrator 4 is connected with Hydraulic Station 8 through hydralic hose 7, is provided with eccentric in the said vibrator 4; Said vibrator 4 is connected with shock absorber 2 through elastic device, and said stay cord 1 is connected with shock absorber 2.
Above-mentioned elastic device is a spring 3.
Above-mentioned eccentric is two eccentric massblocks 9.
When carrying out the pile sinking operation, the periodicity exciting force that vibrator 4 produces makes pile body 6 produce vibration, thereby makes the soil liquefaction of pile body 6 peripheries, and soil reduces the frictional force of pile body 6 greatly like this, and pile body 6 just can sink to soil under the action of gravity of self.The hydraulic-driven power that vibrator 4 provides through Hydraulic Station 8 makes two eccentric massblock 9 generation exciting forces of rotation in opposite directions; The centrifugal force of two eccentric massblock 9 rotation generations is cancelled out each other in the horizontal direction; In the vertical direction mutual superposition; Thereby formed periodic exciting force in vertical direction, as shown in Figure 2.
The hydraulic vibrohammer of the utility model must not leave the space between the head of clamper and stake when the folder stake, and after should treating that pressure meter shows that pressure reaches rated value, can command crane to rise and pull out.During pile pulling, when pile body buries the people and partly is pulled up 1.0～1.5m, should stop vibration, fasten and hang stake and use wire rope, the stake of extricating oneself from a predicament and brace oneself up to action recurs.When the stake point when having only 1～2m, should stop vibration, by the direct pile pulling of crane underground.After treating that stake is extracted fully, before hanging a wire rope and not hanging tight, must not unclamp clamper.Before the pile sinking, should be with the front end location of stake, the verticality of adjustment guide rail and stake should not make gradient surpass 2 °.During pile sinking, the wire rope that hangs stake should loosen immediately following the stake subsidence velocity.Before 3m was gone in stake, stake machine capable of using revolution or guide rod moved forward and backward, and proofread and correct the verticality of stake; When stake people soil surpasses 3m, must not proofread and correct again.In the pile driving process, when the ammeter index sharply rises, should reduce pile sinking speed, make the motor non-overloading; But when the heavy people of stake is too slow, can on vibrohammer, add a certain amount of counterweight.In the operation, when meeting the hydraulic hose breakage, hydraulic cabinet is malfunctioning or has a power failure (comprising fuse opening), answer hard stop, reversing switch is placed on " centre " position, and should takes safety measures, must not let stake from clamper, come off.In the operation, should keep the vibrohammer vibration absorber position that respectively rubs to have good lubricated.After the operation, should vibrohammer be put to lower along guide rod, and adopt wooden unit to pad, the vibrohammer of band stake pipe can insert the stake pipe underground half the.After the operation, except that the master switch that should cut off on the operation panel, still should cut off the switch on the switchboard, and should adopt waterproof cloth that operation panel is hidden.
In sum, just can realize the utility model preferably.
