Abstract
The utility model relates to a special elevator for petroleum drilling. The special elevator for petroleum drilling comprises an elevator casing, oil cylinders with springs are arranged on the upper portion of the elevator casing, two symmetrical connection rod pistons are arranged on the middle portion of the elevator casing, and end caps are connected at one ends of the connection rod pistons. The special elevator for petroleum drilling has the advantage that by integrating a main body of the elevator with the oil cylinders and clamps, fast and flexible clamping and loosing of an oil tube is realized, and the special elevator is safe and reliable.
Description
Technical field
The utility model relates to a kind of special-purpose elevator for oil drilling.
Background technology
In the well site of oil field drilling automation, the elevator of lifting oil pipe is a critical component, to be buckled in below tool joint, sleeve pipe or the tubing coupling, in order to hang, to promote and be lowered to the instrument of drilling rod, sleeve pipe or oil pipe, it is one of the highest instrument of frequency of utilization, should seek quickness speed flexibly to it, require again safe and reliable.But how guaranteeing both to have satisfied elevator to the chucking of oil pipe and unclamp (field requirement), can guarantee its safety again, is that can automation hydraulic pressure elevator be practically applicable to on-the-spot crux.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of special-purpose elevator for oil drilling, but fast and flexible with oil pipe chucking with unclamp, safe and reliable.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of special-purpose elevator for oil drilling comprises the elevator housing, and described elevator housing top is provided with the oil cylinder with spring, and elevator housing middle part is arranged with two connecting rod pistons, and connecting rod piston one end is connected with end cap.
Compared with prior art, the beneficial effects of the utility model are:
Elevator body and each oil cylinder and jig are combined into one, realize fast and flexible with the oil pipe chucking with unclamp, safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-elevator housing 2-oil cylinder 3-connecting rod piston 4-end cap.
The specific embodiment
Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1, a kind of special-purpose elevator for oil drilling comprises elevator housing 1, and described elevator housing 1 top is provided with the oil cylinder 2 with spring, and elevator housing 1 middle part is arranged with two connecting rod pistons 3, and connecting rod piston 3 one ends are connected with end cap 4.
By means of adopting hydraulic power source, elevator body and each oil cylinder and jig are combined into one, connect two master cylinder bonnets with bolt, process the master cylinder steel cylinder in elevator body, adopt two slip-ring seal circles on the oil cylinder, for avoiding the steel to steel contact, adopt the isolation of helical pitch ring between piston rod and steel cylinder, on the piston sealing ring installation site guarantee with hydraulic system in one way valve and the oil cylinder medi-spring piston of accurately opening and rebound in good time, pass through spring, piston and one way valve opening enclosed have consisted of a sequentially-operating, and total consists of oil cylinder 2.Both satisfy the elevator action request, played again the safety effect to elevator.Not only play oil cylinder 2 fixations but also replace cylinder cover on the two ends end cap 4.Appearance is small and exquisite, saves material, has guaranteed again intensity.
The utility model mainly is comprised of 2 oil cylinders 2 with spring, 2 oil cylinders with piston 3,2 end caps 4, owing to adopt hydraulic-driven, has realized fast multifunctional characteristics.Compare with the mechanical elevator of tradition, control is supporting easily with automatically, has improved labor productivity.
The utility model is combined into one elevator body and each oil cylinder and jig, realize fast and flexible with the oil pipe chucking with unclamp, safe and reliable.
