Abstract

The utility model relates to a multifunctional hydraulic power slip which is used for adding or subtracting drilling tools and conducting a drilling operation in the oil or geology drilling operation. The multifunctional hydraulic power slip comprises a seat body, tooth plate bodies, tooth plates, a connecting disc, two-level hydraulic cylinders, a hydraulic swing cylinder, a tooth clutch, a wearing ring, a mud scrapping device, a hydraulic pipeline, a hydraulic control valve and the like. The seat body comprises two halves, the upper portion of an inner hole is square, and the lower portion of the inner hole is cone-shaped. Four two-level hydraulic cylinders and the hydraulic swing cylinder are evenly distributed on the seat body. The connecting disc enables four piston rods of the four two-level hydraulic cylinders to be connected together. Four sets of the tooth plate bodies with outer conical surfaces and inner circular arc surfaces are respectively connected with a piston rod of each two-level hydraulic cylinder through a connecting block and a connecting rod. By means of the multifunctional hydraulic power slip, a big square slip is replaced to transmit torsion, the multifunctional hydraulic power slip is suitable for drilling operations of multi-specifications by changing the tooth plates, and therefore, multifunction of the slip is achieved, the problem that the slip of the existing slip needs to be hoisted away in the drilling operation is resolved, labor intensity is reduced, working efficiency is improved, and safety is enhanced.

Summary of the invention
The purpose of this utility model is: a kind of multifunction hydraulic power slip is provided, and this multifunction hydraulic power slip is comprised of pedestal, two-stage hydraulic jack, swing hydraulic pressure oil cylinder, terminal pad, dental lamina body, dental lamina, connecting rod, contiguous block, gear clutch, wear ring, mud-scraping apparatus, pedestal hinge, dental lamina body container cavity, fluid pressure line and hydraulic control valve.The pedestal central upper is square hole, and the bottom is taper hole; The two-stage hydraulic jack drives the dental lamina body and carries out lifting; The swing hydraulic pressure oil cylinder drives the dental lamina body and is fixed angle swinging; Gear clutch transmits the power of hydraulic pressure oscillating oil cylinder; Pedestal is provided with dental lamina body container cavity.
The present invention's beneficial effect compared with prior art is:
1, finish plus-minus drilling tool operation after, need not slips hung and can carry out drillng operation, reduced workload, improved operating efficiency;
2, reduce the potential safety hazard of frequent lifting slips;
3, replace large quadrel, saved cost;
4, automaticity is high, has reduced labour intensity.
Description of drawings
Fig. 1 is that the utility model is along two two-stage hydraulic jack central cross-sectional view;
Fig. 2 is the utility model top view.
Among the figure: 1, pedestal; 2, two-stage hydraulic jack; 3, swing hydraulic pressure oil cylinder; 4, terminal pad; 5, dental lamina body; 6, dental lamina; 7, connecting rod; 8, contiguous block; 9, second level piston rod; 10, gear clutch; 11, first order piston rod; 12, wear ring; 13, mud-scraping apparatus; 14, pedestal hinge; 15, dental lamina body container cavity.
The specific embodiment:
As shown in Figure 1 and Figure 2, this multifunction hydraulic power slip is comprised of pedestal 1, two-stage hydraulic jack 2, swing hydraulic pressure oil cylinder 3, terminal pad 4, dental lamina body 5, dental lamina 6, connecting rod 7, contiguous block 8, gear clutch 10, wear ring 12, mud-scraping apparatus 13, pedestal hinge 14, fluid pressure line and control valve etc.Pedestal 1 is comprised of two halves, connects with the pedestal hinge 14 of both sides; The top, hole at pedestal 1 center is square hole, and the bottom is conical bore, and the taper hole below is installed with wear ring 12 and mud-scraping apparatus 13; Be uniform-distribution with four two-stage hydraulic jacks 2 along conical bore on the pedestal 1; Be provided with dental lamina body container cavity 15 on each two-stage hydraulic jack next door on the pedestal 1; The piston of each two-stage hydraulic jack 2 and cylinder cap place are provided with gear clutch 10; The second level piston rod 9 of each two-stage hydraulic jack 2 links to each other with terminal pad, and links to each other with dental lamina body 5 with connecting rod 7 by contiguous block 8; The top of each two-stage hydraulic jack 2 is installed with swing hydraulic pressure oil cylinder 3, and its pendulum angle is fixed, and just in time is the angle between dental lamina body 5 operating positions and the dental lamina body container cavity 15; Dental lamina body 5 has the male cone (strobilus masculinus) that matches with pedestal 1 internal taper hole, and interior anchor ring is arranged, and is processed with the groove that dental lamina 6 is installed on the anchor ring, and dental lamina that can be by changing different-diameter is with the job requirements of the drilling tool that adapts to different size; Each hydraulic jack links to each other with hydraulic power supply by pipeline, control valve.
Below be the specific works process of this multifunction hydraulic power slip:
1, Installation and Debugging: check whether attachment bolt is loosening, and whether each fluid pressure line connects correctly, and whether each oil site is normal, after all are errorless slips winched in the preformed hole of rotating disk the locking positioning piece everywhere; The pressure of adjusting hydraulic circuit and flow are to desired value; Operating hydraulically operated control valve, allow slips carry out no-load running, rise, whether flexibly, steadily rotation, decline, rising, rotation, decline do action be more than 3 times, note observing each action, whether each fluid pressure line has oil leakage phenomenon, can carry out loaded work piece after all are normal.
2, add, subtract the drilling tool operation: hang drilling tool with suspension hook first; Handle the two-stage hydraulic oil cylinder control valve, hydraulic oil is entered from four two-stage hydraulic jack 2 bottoms simultaneously, the first order piston rod 11 of two-stage hydraulic jack 2 moves upward simultaneously with four dental lamina bodies 5; First order oil cylinder stroke at the end, second level oil cylinder is started working, second level piston rod 9 moves upward, at this moment, 10 engagements of two gear clutch, four dental lamina bodies 5 are held up to the height that leaves dental lamina body container cavity 15 fully by second level piston rod 9; Operating hydraulically operated oscillating oil cylinder control valve, four swing hydraulic pressure oil cylinders 3 begin to swing, drive the rotation of dental lamina body to the operating position by gear clutch 10, handle again the two-stage hydraulic oil cylinder control valve, hydraulic oil is entered from the top of four two-stage hydraulic jacks 2 simultaneously, second level piston rod 9 and first order piston rod 11 move downwards, driving simultaneously four dental lamina bodies 5 moves downwards, in the process of operation downwards, the inner conical surface wedging of dental lamina body 5 its male cone (strobilus masculinus) and pedestal 1 under Action of Gravity Field, four dental lamina bodies 5 draw in to the center, dental lamina 6 inner arc surfaces on it form a face of cylinder, under the effect of frictional force drilling tool is clamped, can add this moment, subtract the drilling tool operation.When reducing the drilling tool operation, mud-scraping apparatus 13 can scrape the mud that adheres on the drilling tool, skids preventing.Handle the repeatedly rise and fall of piston rod that control valve makes the two-stage hydraulic jack, that can realize drilling tool repeats to add, subtract operation.
3, drillng operation: when carrying out drillng operation, handle the two-stage hydraulic oil cylinder control valve, until second level piston rod 9 rises fully, this moment, dental lamina body 5 bottoms exceeded pedestal 1 upper end, gear clutch 10 engagements; Operating hydraulically operated oscillating oil cylinder control valve makes dental lamina body 5 turn to dental lamina body container cavity 15 places; Handle the two-stage hydraulic oil cylinder control valve, make the two-stage piston rod all be in extreme lower position, this moment, the dental lamina body fell in the dental lamina body container cavity fully; Square bushing on the square hole at pedestal 1 center is in-built can carry out drillng operation.
