Brief description of the drawings
Fig. 1 is structural representation of the invention；
Wherein：1 is support platform, and 2 is rotary digging static pressure platform, and 3 is static pressure implanted device, and 4 is drilling rod, and 5 is derrick, and 6 is hydraulic means, and 7,8 is support frame, and 9 is expansion link, and 10 is hoist cylinder.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with drawings and Examples, the present invention will be described in further detail.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
As shown in figure 1, the present invention is an integrated system, the support platform being mainly made up of an engineering truck and rotary digging static pressure platform, appointed place can arbitrarily be moved to by engineering truck.A support frame 7 and a hydraulic means are provided with support platform to be used to support derrick, and two support frames are provided with derrick, and the support frame 7 on one of support frame and support platform is flexibly connected using bearing pin；Hydraulic means hydraulic stem is flexibly connected with another support frame on derrick by bearing pin.Derrick can be rotated so that parallel derrick is vertically arranged under the promotion of hydraulic means hydraulic stem around the bearing pin of support frame 7.
The top of derrick is provided with constriction device, constriction device includes expansion link and hoist cylinder, and piston rod one end of hoist cylinder is fixed on derrick, and hoist cylinder is fixed on expansion link, hoist cylinder is driven to lift by oil cylinder pushing or contraction piston rod, so as to drive expansion link to stretch.A fixed pulley is respectively provided with telescoping tube and bridge motor, two fixed pulleys are linked together by wirerope, such words bridge motor will be retracted device drive and move up and down.
Static pressure implanted device is arranged on rotary digging static pressure platform, and major part is to slide case, and sliding case has the function of the function and horizontal-clamping for moving up and down.To realize this function, needing to be provided for support and derrick that case is slided in support first；One lateral frame is set, and a derrick for longitudinal direction is set on lateral frame, lateral frame needs to be fixedly connected with derrick.The track that can be slided up and down is set in the inner side of derrick, and the same both sides in slip case set chute so that sliding case can freely slide up and down in derrick along track.In order to ensure the safety of slip case, the size in derrick needs cooperation consistent with the size for sliding case, and after the chute for sliding case is snapped in the track of derrick, both are indissociable.
In order to realize this purpose for moving up and down, the bottom for sliding case is provided with four longitudinal oil cylinders, four longitudinal oil cylinders are evenly distributed on by four angles for sliding bottom face so that whole to slide case uniform force.Piston rod one end of longitudinal oil cylinder needs to be fixedly connected with lateral frame, like this, is done work by oil cylinder and promotes piston rod with regard to slip case can be promoted to move up；Similarly, shrinking piston rod can also cause that sliding case moves down.Certainly, four longitudinal oil cylinders need the synchronous acting of control system control, it is to avoid four longitudinal nonsynchronous words of oil cylinder cause slip case stuck.
In order to realize this purpose of level locking, set in case four horizontal oil cylinders sliding, horizontal oil cylinder is symmetrical set two-by-two.A static pressure fixture is fixedly connected in the front end of horizontal cylinder piston rod, static pressure fixture can be changed according to the difference of static pressure part, static pressure part is generally tabular or tubular.When its piston rod of horizontal oil cylinder pushing is so as to promote static pressure fixture so as to can be achieved with locking of the static pressure fixture to static pressure part, the static pressure part after locking is just connected as an entirety with case is slided certainly.
The center of case is being slided, through hole is being vertically arranged with, through hole is being for through drilling rod, casing and static pressure part.When whole device needs to carry out static pressure implantation, the synchronous piston rod that stretches out is controlled to exert a force to static pressure part static pressure fixture by control system by horizontal oil cylinder first, static pressure part after holding is integral with slip box-shaped, control system controls longitudinal oil cylinder pushing piston rod again, so that slide case moved up along derrick track, so that band dynamic and static pressure part is moved up；When specified location is moved to, longitudinal oil cylinder is stopped doing power, and horizontal oil cylinder then shrinks its piston rod, unclamps the clamping to static pressure fixture, and static pressure part will drop downwards after fixture release according to the gravity of itself, and this impulsive force can tamp ground；Then longitudinal oil cylinder shrinks piston rod and returns to original position again, repeats the implantation operation that whole process can just complete to static pressure part.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, all any modification, equivalent and improvement made within the spirit and principles in the present invention etc. should be included within the scope of the present invention.
