In view of this, for the problems referred to above, propose a kind of reasonable in design and effectively improve the mechanization well workover suspension ring switching device of above-mentioned disappearance, draw brand-new suspension ring dislodging method simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of mechanization well workover suspension ring switching device and mechanization dislodging suspension ring method thereof, constructor can be replaced to complete suspension ring dislodging work at well head.
In order to reach above-mentioned purpose, present invention employs following technical scheme, mechanization well workover suspension ring switching device, comprise the switch arm that suspension ring can be made to strut and back, the drive unit that power is provided for switch arm, described switch arm at least arranges two groups, often organizing switch arm is two at least hinged joint structures, and switch arm lower end is on the drive means hinged, described switch arm of often organizing arranges switch arm wheel in the hinged place of two joint structures, and described switch arm is run in switch arm track by switch arm wheel.
Described switch arm track is V-shape, and is fixed on base plate below.
The straight-arm that described drive unit is switch arm hydraulic cylinder and stretches inside and outside hydraulic cylinder, described switch arm lower end is hinged on straight-arm.
Described switch arm be positioned at suspension ring just under, switch arm rises to insert between suspension ring and suspension ring is strutted to elevator both sides, and decline suspension ring are backed in the hanger of elevator both sides by gravity.
In order to reach another object above-mentioned, present invention employs following technical scheme, mechanization well workover suspension ring switching device carries out mechanization dislodging suspension ring method, the steps include:
Pluck suspension ring method, first, switch arm hydraulic cylinder works, straight-arm bounces back, and drive switch arm in switch arm track forward, open to both sides in V-shape, two suspension ring levels in two hangers are strutted, suspension ring are until strut outside elevator both sides, switch arm hydraulic cylinder quits work, and promotes suspension ring and departs from elevator, finally, switch arm inverse operation runs back raw bits, completes and plucks suspension ring operation;
Hang suspension ring method, first, switch arm hydraulic cylinder works, straight-arm bounces back, and drives switch arm in switch arm track forward, opens to both sides in V-shape, two suspension ring levels are strutted, and suspension ring are until strut outside elevator both sides, and switch arm hydraulic cylinder quits work, decline suspension ring are to the hanger center of elevator both sides, finally, switch arm returns raw bits, and two suspension ring are regained to center under gravity, hanging position, suspension ring lower end enters elevator hanger, completes and hangs suspension ring operation.
Compared to prior art, the present invention has following beneficial effect:
Dislodging suspension ring when the present invention is applicable to mechanization workover treatment, improve well head automaticity, reduce labor strength, and improving working security, is the key technology that mechanization well workover realizes well head Unmanned operation.Realize the operation of mechanized shaftmouth dislodging suspension ring by this technology, be applicable to traditional workover treatment; Effectively alleviate labor strength; Applied widely, improve working security.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of mechanization well workover of the present invention suspension ring switching device.
In figure: 1, switch arm hydraulic cylinder; 2, switch arm track; 3, switch arm; 4, switch arm wheel; 5, base plate; 6, straight-arm.
Detailed description of the invention
Detailed description for the present invention and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the present invention.
According to Fig. 1, a kind of mechanization well workover suspension ring switching device, this suspension ring switching technique mainly comprises switch arm hydraulic cylinder 1, switch arm track 2, switch arm 3, switch arm wheel 4, base plate 5, straight-arm 6.Described switch arm 3 links together with straight-arm 6.Described switch arm 3 is also provided with switch arm wheel 4.Described switch arm wheel 4 can move in switch arm track 2.Described switch track 2 is arranged on base plate 5.Described switch arm hydraulic cylinder 1 is connected with straight-arm 6, retract switch arm hydraulic cylinder 1, and switch arm 3 can be made to strut along switch arm track 2, open switch arm 3, namely open suspension ring, stretch out switch arm hydraulic cylinder 1, switch arm 3 can be made to regain along switch arm track 2, and closing switch arm 3, namely closes suspension ring.
It is as follows that mechanization well workover suspension ring switching device carries out mechanization dislodging suspension ring procedure:
When plucking suspension ring, transfer hook, elevator is made to be seated at well head, hanging position, suspension ring lower end vertical position is in hanger open centre position, two ends, now gauge tap arm hydraulic cylinder 1 is regained, straight-arm 6 is driven to travel forward, switch arm wheel 4 travels forward along switch arm track 2, switch arm 3 is opened, switch arm 3 contacts suspension ring, suspension ring are opened, after suspension ring horizontal level departs from two ends hanger, on carry hook, after suspension ring vertical position departs from switch arm 3, gauge tap arm hydraulic cylinder 1 stretches out, straight-arm 6 is driven to move backward, switch arm wheel 4 moves backward along switch arm track 2, switch arm 3 is closed, complete and pluck suspension ring process.
When hanging suspension ring, transfer hook, make suspension ring lower end vertical position lower than switch arm 3 vertical position, but suspension ring lower end does not contact with below elevator, now gauge tap arm hydraulic cylinder 1 is regained, straight-arm 6 is driven to travel forward, switch arm wheel 4 travels forward along switch arm track 2, switch arm 3 is opened, switch arm 3 contacts suspension ring, suspension ring are opened, after suspension ring horizontal level departs from two ends hanger, transfer hook, hanging position, suspension ring lower end vertical position is made to be positioned at the center of below elevator hanger suspension mouth, now, gauge tap arm hydraulic cylinder 1 stretches out, straight-arm 6 is driven to move backward, switch arm wheel 4 moves backward along switch arm track 2, switch arm 3 is closed, two suspension ring are regained to center under gravity, hanging position, suspension ring lower end enters elevator hanger, complete and hang suspension ring process.
The foregoing is only preferred embodiment of the present invention, be not used 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.
