Description
Technical field
The utility model relates to a kind of drive unit of rig, particularly relates to a kind of all-hydraulic drilling follow tube drive device that is applicable to the major diameter drill while drilling and casing of boring slip casting preformed pile (CRG stake) stake type construction.
Background technology
Major diameter drill while drilling and casing is a kind of building pile foundation novel pore-forming equipment of constructing that is applied to.It will be pressed into the stratum with the prefabricated tubular pile vibration by the drilling follow pipe unit by in the auger stem drilling and forming hole, plays the effect of aperture retaining wall.After pore-forming finishes, according to stake hole designing requirement preformed pile is stayed in the hole directly placing of concrete or preformed pile is extracted aperture placing of concrete again, even be directly to use the preformed pile pile, and need not placing of concrete.The function of major diameter drill while drilling and casing driving prefabricated tubular pile realizes by all-hydraulic drilling follow tube drive device just.
Very similar with the drilling follow tube drive device is the vibrator that is applied on the vibrating hammer, and the principle that they produce exciting force is consistent, all is the exciting force that produces vertical direction by the rotation of eccentricity excitation piece.But the vibrator on the vibrating hammer can only be used for independent vibration construction, and can't construct simultaneously with auger stem.Especially, the greatest problem of vibrator is the realization of frequency modulation accent square.The vibrating hammer vibrator generally is that the phase difference of two-layer eccentricity excitation piece was realized frequency modulation accent square about employing gear drive rigidity changed synchronously both at home and abroad.Adopt this mode to realize frequency modulation accent square, have two big defectives: first vibrator mechanical mechanism is too complicated, the high and maintenance inconvenience of cost of production; It two is because high-speed gear running must cause high temperature, and makes that because of the eccentric block action of centrifugal force bending of gear main shaft, the overlap coefficient of gear reduce, and then causes that gear-driven impact shock, noise increase and the bearing capacity decline of gear.Therefore, driving members such as gear are easy to damage, and whole vibrator mechanical system reliability is not high.
The utility model content
Technical problem to be solved in the utility model provides a kind of rig that makes when using auger stem to creep into, and can follow the all-hydraulic drilling follow tube drive device of major diameter drill while drilling and casing that drilling rod is pressed into the stratum together by the vibratory drive prefabricated tubular pile.
In order to solve the problems of the technologies described above, the all-hydraulic drilling follow tube drive device of the major diameter drill while drilling and casing that the utility model provides, on casing, connect to be provided with and be convenient to the conduit that auger stem passes through, on described casing, be provided with safe guide holder and the damping spring being convenient to connect at the native lower box part of storage, on described casing with described conduit for axially being symmetrically installed with two eccentricity excitation pieces and eccentric block installation shaft and axle bed, vibrating motor is installed on the described casing and by shaft coupling and is connected with described eccentric block installation shaft, and corresponding first pile cover that is used for installing and locating preformed pile with described conduit is installed below described casing, pile holder and folder stake oil cylinder thereof.
As a kind of improvement of the present utility model, in described first pile cover, second pile cover is installed.
Adopt the all-hydraulic drilling follow tube drive device of major diameter drill while drilling and casing of technique scheme, two eccentric block installation shaft respectively are equipped with two eccentricity excitation pieces, vibrating motor drives two eccentric block installation shaft by shaft coupling and rotates in opposite directions, and then make four eccentricity excitation pieces rotate in opposite directions in twos, the horizontal exciting force direction of its generation is cancelled each other on the contrary, vertical exciting force is stack mutually then, therefore makes whole drilling follow tube drive device up-down vibration produce driving force.When under different geological conditionss, constructing, flow by regulation of hydraulic system hydraulic vibration motor, just can reach drilling follow pipe unit frequency modulation and transfer the purpose of square, and the gear frequency modulation that need not vibrator complexity on the vibrating hammer is transferred moment device, makes that whole frame for movement is simple, fault rate is low, maintaining is convenient, long service life, low cost of manufacture.The rotary drilling of vibration of the present utility model and auger stem is carried out simultaneously, auger stem can pass the drilling follow pipe unit by conduit and be rotated drilling construction in the prefabricated tubular pile the inside, thereby has realized the drilling follow pipe function of major diameter drill while drilling and casing.In drilling follow pipe unit when construction vibration, can fix prefabricated tubular pile and lead by two pile holders of two folder stake hydraulic oil cylinder driving of bottom, with carrying out smoothly of guaranteeing that pile tube is pressed into.Simultaneously, the drilling follow pipe unit can make up by the different mounting or dismounting of first pile cover and second pile cover, prefabricated tubular pile that can two kinds of different apertures of vibratory drive.The utility model is connected with the native case of storage by four damping springs, plays the damping, buffering effect.Safe guide holder can play good guide effect to the up-down vibration of whole device; and when damping spring lost efficacy because of a variety of causes such as fatigues; whole device is unlikely to because the connection of four safe guide holders is arranged to fall from the high-altitude and causes construction accident, plays good safeguard protection effect.
In sum, the utility model is that a kind of rig that makes is when using auger stem to creep into, prefabricated tubular pile that can two kinds of different apertures of vibratory drive follows that drilling rod is pressed into the stratum together and fault rate is low, simple in structure, maintaining is convenient, long service life, the all-hydraulic drilling follow tube drive device of the major diameter drill while drilling and casing of low cost of manufacture.
