As preferably, described slips cross section is trapezoidal, is provided with guide vane and caging bolt groove, and slip sleeve is cylindrical, and upper end is provided with screw thread and coordinates with slip spider.
Compared with prior art, the beneficial effects of the utility model are: rational in infrastructure, tubing string and rotatable can be pressurizeed, be promoted in easy to operate and optional position.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the utility model Fig. 1 left view.
Fig. 3 is A partial enlarged view in the utility model Fig. 1.
In figure: 1. suspension ring connecting rod, 2. suspension ring baffle plate, 3. locking device, 4. coaster body, 5. slotted nut, the 6. heavy collar, 7. anti-pressure rod, 8. upper press cover of wire rope, 9. upper centring thrust bearing, 10. boom hoist cable, 11. rotary sleeves, 12. slip spiders, 13. slip sleeve, 14. slips, 15. spacing spiral shells, 16. suspension ring connecting rod back of the body caps, 17. the center downward regulating thrust bearing, 18. anti-pressurization wire rope, 19. suspension ring, 20. hydraulic fluid port a, 21. hydraulic fluid port b, 22. wire rope baffle plates.
The specific embodiment
, in order more clearly to understand the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further illustrated.
as Fig. 1, Fig. 2, a kind of rotary traveling slip coaster shown in Figure 3, comprise the coaster body, the slips rotating part, coaster body 4 is cylindrical for rectangular structure bottom, top, boom hoist cable 10 is walked around the steel wire rope groove of coaster body 4 two sides, is furnished with wire rope baffle plate 22, anti-pressure rod 7 is arranged in the side screwed hole of coaster body 4, tail end is installed the heavy collar 6 of wire rope, slotted nut 5 is at the heavy collar 6 sides of wire rope, the heavy collar 6 of wire rope connects anti-pressurization wire rope 18, middle processing shoulder hole inside is that center downward regulating thrust bearing 17 is installed in slips rotating part lower end, cylindrical lower end has lockhole.
described slips rotating part comprises upper press cover 8, upper centring thrust bearing 9. rotary sleeves 11, slip spider 12, slip sleeve 13, slips 14, caging bolt 15, upper press cover 8 is bolted coaster body 4, aligning thrust bearing 9 is installed in upper press cover 8 upper ends, rotary sleeve 11 casing walls have oil duct, rotary sleeve 11 upper ends are passed upper centring thrust bearing 9 and are installed on upper press cover 8 inside, slip spider 12 upper ends are passed rotary sleeve 11 and with rotary sleeve 11, are coordinated and form annular chamber, lower end is processed with the slips rail groove of 10-20 °, coordinate with the slips guide vane, caging bolt 15 passes slips 14 and is screwed into slip sleeve 13.
Oil-feed and the fuel-displaced slip spider 12 of controlling by hydraulic fluid port a20 and hydraulic fluid port b21 rise and descend, and during hydraulic fluid port a20 oil-feed, slip spider 12 moves down, and utilizes the inclined plane of slip spider 12 to make 14 centripetal guiding movements of slips, the chucking tubing string; Hydraulic fluid port b21 oil-feed, slip spider 12 moves up, and slips 14 is put card.Its advantage is that the inner rotatable slips that need not discharge of coaster also can complete upper, the shackle of tubing string, and caging bolt 15 restriction slips 14, not there will be stuck.
When tubing string deadweight acted on the upper top power of tubing string greater than borehole pressure, suspension ring 19 hung up elevator and can complete the disposable lifting of tubing string or transfer by boom hoist cable 10; When tubing string deadweight acts on upper top power on tubing string less than borehole pressure, act on simultaneously the rotation slips by anti-pressurization wire rope 18 and boom hoist cable 10, tubing string passes rotation slips coaster central passage, hydraulic fluid port a20 oil-feed, slip spider 12 moves downward, promote slips 14 and hold tubing string tightly, complete tubing string and promote or transfer; Its advantage, because slip spider 12 has the inclined plane groove, can form reverse self-locking to tubing string; When down-hole pressure was larger, self-locking was tighter, and while not there will be slips 14 to hold tubing string tightly, tubing string is not ejected because down-hole pressure is large, but holding card tubing string optional position promotes, transfers.
The above is only preferred embodiments of the present utility model,, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
