Abstract
A chuck type hanging elevator is applied to oil pipe lifting and lowering in oil fields. Is characterized in that: the two sides of the elevator are symmetrically provided with lifting lugs, the lifting lugs on the two sides of the elevator are respectively hung at the lower end of the lifting ring, the lower plane of the elevator is provided with screw holes, the chuck type hanging elevator is fixed on the lower plane of the elevator through screws, and the central hole of the chuck type hanging elevator is opposite to the central hole of the elevator. The effect is as follows: the lifting device is always suspended on a lifting ring of a lifting system, and can clamp oil pipes and columns, so that the lifting operation of the oil pipes and the columns with different sizes can be realized. The turnover mechanism matched with the wellhead can avoid actions of repeatedly picking and hanging the elevator, and can stop drill dropping accidents and reduce labor intensity of workers, thereby realizing the operation of lifting and lowering the oil pipe by the single elevator. The operation is convenient and fast, the number of well mouth operators is reduced, the labor intensity of workers can be reduced, and the operation of lifting and lowering the oil pipe by a single elevator is realized.
Description
Technical field
The utility model relates to lower oil tube operation technique field, oil field, and particularly a kind of special tool of lower oil tube operation is that a kind of chuck mode hangs elevator.
Background technology
At present, the employed suspension elevator of oil field lower oil tube operation mostly is valve elevator and crescent moon elevator.These two kinds of elevators need special operating personnel repeatedly to pluck, hang in use, and workload is heavy, and dead oil, wax deposition very easily cause the switch of elevator not smooth, cause falling the generation of brill accident.Along with the raising of well head operating automation degree, these two kinds of elevators no longer have been fit to current development trend.
The utility model content
The purpose of this utility model is: provide a kind of chuck mode to hang elevator.All the time be suspended on the suspension ring of workover rig Hoisting System, cooperate the switching mechanism of well head, finish the clamping to oil pipe.
The technical solution adopted in the utility model is: chuck mode hangs elevator, comprise that chuck body, chuck mode hang elevator and suspension ring, the bilateral symmetry of elevator has hanger, the both sides hanger of elevator is suspended on respectively the lower end of suspension ring, it is characterized in that: the lower plane at elevator has screw hole, chuck mode hangs elevator and is fixed by screws on the lower plane of elevator, and the centre bore that chuck mode hangs elevator is relative with the centre bore of elevator.
The operating principle that the summary chuck mode hangs elevator.Consult Fig. 1.Chuck mode hangs in the elevator 2 bevel gear wheel, and the flat thread structure at the bevel gear wheel back side and the bottom of movable jaw are intermeshing; The side that chuck mode hangs elevator 2 is equipped with hydraulic motor, and hydraulic motor is connected with bevel pinion, and bevel pinion and big vertebra gear are intermeshing; The lower plane that chuck mode hangs elevator 2 has with equally distributed three movable jaws in 120 degree angles, and movable jaw can slide in the fixedly sliding rail of chuck body 1; The hydraulic motor that chuck mode hangs elevator 2 is connected with the hydraulic line of workover rig, and hydraulic motor rotates and drives three movable jaws that chuck mode hangs elevator 2, chucking oil pipe 4.The Chinese patent that the structure of chuck mode suspension elevator 2 has been applied for is not described in detail.
The beneficial effects of the utility model: the utility model chuck mode hangs elevator, hangs on all the time on the suspension ring of Hoisting System, can carry out clamping to tubing string, realizes the rountrip of different size oil pipe, roofbolt.Cooperate the switching mechanism of well head, not only can avoid repeatedly plucking, hanging the action of elevator, and can stop brill accident, reduction workman's labour intensity, thereby realize the operation of single elevator lower oil tube.Operate convenient, fast, not only reduce well head operating personnel's quantity, and can reduce workman's labour intensity, realize the operation of single elevator lower oil tube.
Description of drawings
Figure l is that the utility model chuck mode hangs the Elevator structure schematic diagram.
Among the figure, the 1-elevator, the 2-chuck mode hangs elevator, 3-suspension ring, 4-oil pipe.
The specific embodiment
Embodiment 1: hang elevator as example take a chuck mode, the utility model is described in further detail.
Consult Fig. 1.The utility model comprises that chuck body 1, chuck mode hang elevator 2 and suspension ring 3, and the bilateral symmetry of elevator 1 has hanger, and the both sides hanger of elevator 1 is suspended on respectively the lower end of suspension ring 3.Lower plane at elevator 1 has screw hole, and chuck mode hangs elevator 2 and is fixed by screws on the lower plane of elevator 1, and the centre bore that chuck mode hangs elevator 2 is relative with the centre bore of elevator 1.
Claims (1)
