Abstract
The invention discloses a method and a special device for automatically picking and suspending lifting rings. The method comprises a lifting ring suspending procedure and a lifting ring picking procedure; when the lifting rings are required to be suspended, a large hook hooks a lifting lug, the special device for automatically picking and suspending the lifting rings is down passed to the position of an elevator at the wellhead, so that corresponding round holes in the lower ends of the two lifting rings mounted on rails of a framework through pulleys are flush with the elevator, the two lifting rings are located on two sides of the elevator, a hydraulic cylinder retracts, the lifting rings move inwards in parallel along the rails of the pulleys and are suspended to the elevator, and the lifting ring suspending procedure is completed; and when the lifting rings are required to be picked, the hydraulic cylinder is stretched out, the two lifting rings move outwards in parallel along the rails of the pulleys and are picked from the elevator, and the lifting ring picking procedure is completed. The device enables the lifting rings to perform relative motion, a mechanical arm is omitted, and the operation is simple; and when the lifting ring are suspended, the hydraulic cylinder has a mechanical lock function, the link that a pin is penetrated through the elevator is omitted, and simplicity and safety are realized.
Description
Technical field
The present invention relates to the suspension ring in the do mechanization operation of petroleum industry, specifically a kind of method of automatic picking off and hanging suspension ring and special purpose device thereof.
Background technology
In mechanization workover treatment, the link of automatic picking off and hanging suspension ring, is by mechanical arm, suspension ring to be seted out at present, specific operation process is like this: in the time that needs are hung suspension ring, mechanical arm reaches well head top position, and both arms are positioned at suspension ring outside, both arms shrink inwards, and suspension ring are hung into elevator.In the time that needs are plucked suspension ring, mechanical arm reaches well head top position, and both arms are positioned at suspension ring inner side, and both arms expand outwardly, and suspension ring are extracted in elevator.This mode of operation, needs extra mechanical arm to coordinate, mechanical arm complex structure, and cost is high, and the requirement of manipulator motion track accuracy is high, easily occurs maloperation.
In view of this, for the problems referred to above, propose a kind of reasonable in designly and effectively improve the special purpose device of the automatic picking off and hanging suspension ring of above-mentioned disappearance, give the method for brand-new automatic picking off and hanging suspension ring simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of method and special purpose device thereof of automatic picking off and hanging suspension ring, can realize the link of suspension ring automatic picking off and hanging in mechanization workover treatment by the present invention, thoroughly solve the problem that prior art exists.
In order to reach above-mentioned purpose, the present invention has adopted following technical scheme, a kind of method of automatic picking off and hanging suspension ring, its step comprises hangs suspension ring operation and plucks suspension ring operation, need to hang suspension ring time, hook hooks hanger transfers the special purpose device of these automatic picking off and hanging suspension ring to wellhead lifting-clamping position, the corresponding circular hole that is arranged on two suspension ring lower ends on the track of skeleton by pulley is flushed with elevator, and two suspension ring are positioned at elevator both sides, hydraulic cylinder shrinks, suspension ring inwardly move along the parallel track of pulley, hang into elevator, complete and hang suspension ring operation; Need to pluck suspension ring time, hydraulic cylinder stretches out, and two suspension ring outwards move along the parallel track of pulley, in elevator, extracts, and completes and plucks suspension ring operation.
In order to reach above-mentioned another object, the present invention has adopted following technical scheme, the special purpose device of automatic picking off and hanging suspension ring, it is characterized in that, comprise skeleton, center, described skeleton upper end is provided with hanger, and skeleton below is connected with two suspension ring that left and right relatively moves automatically, and two suspension ring bottoms are corresponding coaxial-type extension circular hole.
Described suspension ring are connected on the track on skeleton by the pulley formula of horizontally slipping, and described track is arranged on two rectangular openings that skeleton offers.
Between described two suspension ring, be connected with and can make two suspension ring further each other and stretch self-checking device far away.
Described self-checking device is the hydraulic cylinder of level connection joint between two suspension ring.
Compared to prior art, the present invention has following beneficial effect:
1, install and self can make suspension ring do relative motion, save mechanical arm, simple to operate.
2, while hanging into suspension ring, hydraulic cylinder has mechanical lock function, and the link of saving elevator and wearing pin is simple and safe.
Brief description of the drawings
Fig. 1 is the structural representation of the special purpose device of a kind of automatic picking off and hanging suspension ring of the present invention.
In figure: 1, hanger; 2, skeleton; 3, pulley; 4, suspension ring; 5, hydraulic cylinder.
Detailed description of the invention
Relevant detailed description of the present invention and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing only provides the use of reference with explanation, is not used for the present invention to be limited.
Shown in Fig. 1, a kind of special purpose device of automatic picking off and hanging suspension ring, comprises hanger 1, skeleton 2, pulley 3, suspension ring 4, hydraulic cylinder 5 five major parts.Circular hole on hanger is connected with the hook of workover rig, and lower end is together with frame welding.Above skeleton, have two rectangular openings, two suspension ring are suspended on skeleton by rectangular opening, and there is pulley suspension ring and skeleton junction.Between two suspension ring, there is two-way hydraulic cylinder 5.Under the effect of hydraulic cylinder, two suspension ring can do relative motion by pulley on skeleton.
Specific implementation process is such, and need to hang suspension ring time, hook transfers this device to wellhead lifting-clamping position, the circular hole of suspension ring lower end is flushed with elevator, and two suspension ring are positioned at elevator both sides, hydraulic cylinder contraction, suspension ring inwardly move along the parallel track of pulley, hang into elevator.Need to pluck suspension ring time, hydraulic cylinder stretches out, and suspension ring outwards move along the parallel track of pulley, in elevator, extracts.
The foregoing is only preferred embodiment of the present invention, non-in order to limit the scope of the claims of the present invention, other use the equivalence of patent spirit of the present invention to change, and all should all belong to the scope of the claims of the present invention.
