Abstract
The utility model provides an oil pipe elevator which comprises a left half portion and right half portion, wherein the left half portion and the right half portion are mutually connected in a rotatable mode. The left half portion and the right half portion comprise elevating rings, and handles, and semi-cylinder-shaped through grooves, wherein the elevating rings and the handles are respectively symmetrically arranged on the outer side walls of the left half portion and the right half portion, and the through grooves are symmetrically arranged on the inner side walls of the left half portion and the right half portion. The left half portion and the right half portion are fixed together through a clamping device which comprises a clamp buckle and a clamp groove, wherein the clamp buckle is arranged on the left half portion and the clamp groove is formed in the right half portion. The oil pipe elevator has the advantages of being simple in structure, simple in operation, and firm and stable in connecting.
Description
Technical field
The utility model relates to the petroleum drilling and mining field of tool, especially relates to a kind of pipe elevator.
Background technology
Pipe elevator is to hoist in the petroleum drilling and mining or the special tool of the tubing string that descends, and is a kind of instrument of the tubing such as drilling rod, oil pipe and sleeve pipe that are used for slinging.It is suspended on the suspension ring the inside of Hoisting System hook both sides, in order to well is tripped out or is lowered to the operation of drilling tool and oil pipe, sleeve pipe.Existing pipe elevator is generally a moon dentition formula elevator, opens and closes back and forth by elevator handle pulling lift sub crescent.Because the frequent switch of lift sub crescent, cause elevator handle pin loosening, the handle connecting bolt that is connected with lift sub crescent is rotated move back and buckle or come off, the lift sub crescent that causes being attached thereto comes off, and affects to keep the safety in production
