Preventer bearing 108 is installed, preventer bearing 108 fixing preventer when transporting on carrying platform 102.Carrying platform 102 1 sides are provided with annular preventer bearing 108, when the well head bore is unified, ram preventer directly can be installed to carrying platform 102.Only dismantle annular preventer during transportation, be installed on the preventer bearing 108 on side, to prevent the equipment superelevation.
The end of carrying platform 102 is equipped with folding the first pedal 201, the first pedals 201 in deployed condition, the enlarged areas of carrying platform 102.Carrying platform 102 both sides adopt folding deployable flooring structure, and the first pedal 201.During the transportation of well head stabilizer, the first pedal 201 is folding, makes carrying platform 102 not super wide; During use, the first pedal 201 launches, and guarantees broader working space.
The end of working platform 106 is equipped with folding the second pedal 602, the second pedals 602 in deployed condition, the enlarged areas of working platform.Set level during work and can hold 11 "-the 20M ram preventer.
Each liftable supporting leg comprises: pull bar 301, supporting leg micro-adjusting mechanism 302, hanger 303.Supporting leg micro-adjusting mechanism 302 is installed on the bottom of pillar 103, and supporting leg micro-adjusting mechanism 302 is hydraulic mechanism.Supporting leg micro-adjusting mechanism 302 is piths of carrying platform 102 horizontal adjustment of well head stabilizer.Adopt supporting leg micro-adjusting mechanism 302 to make the well head stabilizer can adapt to higher well head.The length of pull bar 301 is adjustable, and pull bar 301 is connected between pillar 103 and carrying platform 102.Pull bar 301 supports or tension liftable supporting leg, improves structural stability.Hanger 303 is installed on the top of pillar 103.Hanger 303 is used for lifting by crane pillar 103 when regulating height.
Shown in Fig. 6, the utility model embodiment is along the sectional drawing of E-E in Fig. 3, and supporting leg span governor motion 105 comprises hydraulic cylinder, Driven by Hydraulic Cylinder supporting leg span governor motion 105 turnover spatial accommodations 501.Hydraulic cylinder comprises hydraulic pressure inner tube 502 and hydraulic pressure outer tube 503.Hydraulic pressure inner tube 502, under the promotion of hydraulic pressure outer tube 503, drives 105 motions of supporting leg span governor motion.The setting of hydraulic cylinder, can make the well head stabilizer with launching fast or shrinking, and saved a large amount of manpowers.
Shown in Fig. 7, the pillar of liftable supporting leg is cylinder.The structure that pillar adopts multistage to connect.Like this, when the height of a certain well head surpasses the height of pillar, can be lengthened pillar, so just can be so that well head stabilizer of the present utility model meets the needs of different well head height.
Below introduce in detail the course of work of the present utility model.
Well head stabilizer in the utility model embodiment, first select suitable quick change flange according to concrete well head bore before upper well, the quick change flange is installed on carrying platform 102, ram preventer can also be installed on the quick change flange in advance according to specific circumstances.
During work, the well head stabilizer is hung oneself from haulage vehicle, according to the height of well head, roughly determine the bearing height of the pillar 103 of liftable supporting leg, the well head stabilizer is hung to pithead position, sit on the flange of well head.Regulate supporting leg span governor motion 105, make the liftable supporting leg of well head stabilizer reach rational span, to reach best support strength.Then by the height of supporting leg micro-adjusting mechanism 302 fine setting pillars 103, the state that carrying platform is up to the standard, fixing wellhead flange bolt simultaneously.
The pull bar 301 of liftable supporting leg is installed, is fixed four liftable supporting legs, make carrying platform 102 more firm.
The first pedal 201 of bulwark ladder 107, expansion carrying platform 102 is installed, the guardrail on carrying platform 102 is installed.
Height is as required installed and is regulated working platform 106, regulates the height of working platform 106 by working platform supporting leg 601.Platform 106 second pedals 201 of organizing work, installation work platform 106 guardrails.Shown in Fig. 2, top view when the utility model embodiment is used, now the well head stabilizer is duty, each parts have all assembled.
Shown in Fig. 3 and Fig. 4, the eclipsed form telescopic outrigger, launch span large, compact after shrinking, and can use common truck transport fully; The stretching, extension of supporting leg adopts hydraulic-driven, can rapid deployment.When not using, the volume of the well head stabilizer after contraction has very greatly and reduces, convenient transportation.
Shown in Fig. 5, be the sectional drawing of the utility model well head stabilizer, we can more be well understood to the structure of the utility model well head stabilizer.
Above-described is preferred embodiment of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not breaking away under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
