Abstract
The utility model discloses a pipe column hoisting device, and relates to a hoisting device of an oil pipe column. The pipe column hoisting device comprises a sling seat. A sling ring is arranged on the sling seat. Clamp teeth which are movably connected with the sling seat are arranged on the lower portion of the sling seat. Clamp points are arranged on the clamp teeth, and wedges are arranged on the lower portions of the clamp points. According to the pipe column hoisting device, an oil pipe coupling can be conveniently connected on the clamp teeth in a sleeved mode, and the pipe column can be hoisted by utilizing of the sling ring. The pipe column hoisting device is simple in structure, and strong in practicality.
Description
Technical field
The utility model relates to a kind of running and pulling device of oil pipe column.
Background technology
Oil well repairing operation mainly is for the normal production that guarantees oil well or according to need of production, oil well is overhauled, safeguards and adjusts, it is the important production link that guarantees oilfield stable production, high yield, its groundwork has inspection pump, sand control, changes filter, changes envelope etc., one of them very hard work be exactly lower oil tube, sucker rod and downhole tool.China's oil well is continued to use traditional operating type always for many years, realized the lower tubular column operation with the crescent moon elevator, complex procedures, automaticity is low, labour intensity is large, need that personnel are many, inefficiency, operation are dangerous large, domestic each oil field has a large amount of workover rigs, such as tractor hoist, derrick, hydraulic tongs, elevator etc., the workover treatment mode is badly in need of reform, but can not all abandon, external vehicle carried well repairing machine better performances, but condition of work requires high, expensive, increased cost of production, be unsuitable for China's national situation.
Summary of the invention
The utility model is intended to propose a kind of by clamping oil pipe body, plays the tubing string running and pulling device of lower tubular column.
Described a kind of tubing string running and pulling device described in the utility model comprises flap seat, and flap seat is provided with suspension ring, and the flap seat bottom is provided with the card tooth that is flexibly connected with it, and Ka Yashang is provided with stuck point, and the stuck point bottom is wedge shape.
Preferably, described flap seat is connected with card tooth wedge shape.
Preferably, also be provided with elevator between described flap seat and the card tooth.
A kind of tubing string running and pulling device described in the utility model can be socketed in Ka Yashang with tubing coupling easily, and is then utilizing suspension ring that tubing string is removed, simple in structure, practical.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Among the figure: the 1-flap seat; The 2-elevator; 3-card tooth.
The specific embodiment
Embodiment 1.
A kind of oil pipe running and pulling device described in the utility model comprises flap seat 1, and flap seat 1 is provided with suspension ring, flap seat 1 bottom is provided with elevator 2, and elevator 2 bottoms are provided with the card tooth 3 that is flexibly connected with it, and card tooth 3 bottoms are provided with, card tooth 3 tops are provided with the stuck point card, and the stuck point bottom is wedge shape.
When playing lower tubular column, when inclined-plane below the card tooth 3 is run at the tubing coupling position, box cupling push card tooth 3 is along the inclined-plane upward sliding, card tooth 3 is up can to make box cupling pass through smoothly when sliding into peak, because the diameter of tubing section less than the diameter of box cupling, therefore blocks tooth 3 owing to do not had to stop, at the lower horizontal reset of Action of Gravity Field, with the box cupling position chucking of oil pipe, the suspension ring of lifting seat 1 can remove tubing string on this moment firmly.
