Abstract
The utility model discloses a slip type elevator, which is mainly used for clamping and lifting pipe columns such as an oil pipe, a drill collar and a casing, in particular for clamping and lifting a flush joint casing and an integral joint oil pipe. The utility model is provided with an elevator body, and is characterized in that the elevator body is in an open type structure, and the middle of the elevator body is provided with tapered bores, and the slip for clamping the pipe column is arranged in the tapered bore. The utility model has the beneficial effect that the utility model has novel structure, convenient use, safe and reliable clamping and lifting, being in particular suitable for clamping and lifting of the flush joint casing and the integral joint oil pipe. The utility model can be used for clamping and lifting various pipe columns by replacing a tooth plate or a slip body.
Description
Technical field:
The utility model relates in oil brill, the workover treatment, is used to promote oil pipe, drill collar, drilling rod, sleeve pipe, does not especially have the slip-type elevator that holds and promote of FJL Casing, IJTBG.
Background technology:
Existing tapering elevator, platform rank elevator can only hold 18 ° of frustum rank peace step tubing strings, to no FJL Casing, IJTBG, are difficult to use, and can't hold and promote.
Summary of the invention:
The purpose of this utility model provide a kind of novel structure, easy to use, hold and promote safe and reliable, be particularly useful for not having FJL Casing, the slip-type elevator that holds and promote of IJTBG.
Technical solution of the present utility model is: a kind of slip-type elevator, the elevator body is arranged, and it is characterized in that: the elevator body is the opposite opened structure, the design of elevator body center has conical bore, and the slips that holds tubing string is installed in the conical bore.
Slips described in the utility model is multiple-piece, and the structure that can move along the conical bore easy on and off.Be equipped with on the slips body and be used to hold the tubing string dental lamina, dental lamina is 360 ° of full structures of surrounding.Be equipped with on the slips body in order to the pressing plate of fixing dental lamina with in order to guarantee the consistent locating ring of each sheet slips body action.The elevator body is made up of left elevator body of splitting and right elevator body.Elevator body one end is connected by bearing pin, and the other end is a lock bolt, and the elevator body can rotate around bearing pin.The slips body links to each other with the elevator body by bolt, stage clip.The slips body back side also is taper seat, and is consistent with the elevator taper seat.
The beneficial effects of the utility model are: novel structure, easy to use, hold and promote safe and reliable, be particularly useful for not having FJL Casing, the slip-type elevator that holds and promote of IJTBG.Change dental lamina or slips body and can adapt to holding and promoting of multiple tubing string.
