Description
Technical field
The utility model relates to a kind of when maintenance oil/gas drilling hydraulic blow out preventer, the portable preventer fluid cylinder of the hydraulic pressure flashboard axis handler that preventer fluid cylinder flashboard axis is loaded and unloaded.
Background technology
In maintenance hydraulic blow out preventer and chance accident (aging like the liquid cylinder piston seal, when drilling crew used preventer, the flashboard axis hook ruptured), removing and change flashboard axis is a great problem.Because other preventer sealing property of pressure level is high, the sealing position is very tight, and the well control mechanic does not have any mechanical and can use, the original method of work dismounting fluid cylinder flashboard axis that can only beat with sledge hammer.
And, use the well of 70MPa, 105MPa preventer more, more extensive along with the variation of casing programme.Intractable often when overhaul and processing accident was met repeatedly the 70MPa ram preventer like the well control workshop and can't be dismantled flashboard axis and send former factory and office reason.Flashboard axis hook fracture emergency service was also met by drilling team; Can only take turns to beat with sledge hammer the workman of drilling team, harm be a lot of like this, and the one, seal is easily because of uneven being sheared of exerting oneself; The 2nd, flashboard axis hits impaired in the process of beaing easily; The 3rd, prolong a lot of repair times, cause very big harm for well control safety, form major safety risks.
Summary of the invention
The purpose of the utility model is to overcome the problems referred to above that exist when having ram preventer dismounting flashboard axis now; The portable preventer fluid cylinder of a kind of hydraulic pressure flashboard axis handler is provided; The utility model replaces heavy manually-operated in the time of can and speedily carrying out rescue work in maintenance; Without power supply and source of the gas, but with a hand pump remote-controlled operation, and can not cause the damage of seal and flashboard axis.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following:
The portable preventer fluid cylinder of a kind of hydraulic pressure flashboard axis handler; It is characterized in that: comprise jacking cylinder, guide post, oil cylinder backstay, positioning seat, oil cylinder top, oil cylinder fixed block and guide pad; Said guide post passes guide pad and is fixed on the preventer through the positioning seat on the guide post; Jacking cylinder is fixed on the oil cylinder fixed block, and the oil cylinder top is connected on the piston rod of jacking cylinder, and guide pad and oil cylinder fixed block are socketed in respectively on the oil cylinder backstay.
Said oil cylinder backstay passes guide pad and oil cylinder fixed block respectively, and guide pad and oil cylinder fixed block are slidingly arranged on the oil cylinder backstay.
The screw mandrel of said guide post is provided with the nut spacing to guide pad.
Said oil cylinder top is threaded on the piston rod of jacking cylinder.
Said jacking cylinder is fixed by bolts on the oil cylinder fixed block.
Adopt the advantage of the utility model to be:
One, the utility model can replace heavy manually-operated in maintenance with speedily carry out rescue work the time, without power supply and source of the gas, but with a hand pump remote-controlled operation, has easy to carryly, use simply, and time-saving characteristics, and can not cause the damage of seal and flashboard axis.
Two, in the utility model, guide pad can be done the front and back position adjustment along guide post, does the adjustment of position, the left and right sides along the jacking cylinder backstay, and the oil cylinder fixed block can be done the adjustment of position, the left and right sides along the oil cylinder backstay, and the preventer that can adapt to different size, specification uses.
Description of drawings
Fig. 1 is the utility model structural representation
Be labeled as among the figure: 1, nut, 2, jacking cylinder, 3, guide post, 4, the oil cylinder backstay, 5, positioning seat, 6, the oil cylinder top, 7, the oil cylinder fixed block, 8, guide pad.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.As shown in the figure, guide post 3 can be fixed on the preventer through positioning seat 5, and guide post 3 penetrates guide pad 8, and nut 1 tightens on the screw mandrel of guide post until withstanding guide pad 8; 4 M10 of oil cylinder 2 usefulness are bolted on the jacking cylinder fixed block 7, and top 6 usefulness of jacking cylinder are threaded on the oil cylinder piston bar; Oil cylinder backstay 4 penetrates in guide pad 8 and the oil cylinder fixed block 7; According to the fluid cylinder size adjusting guide pad 8 of preventer and the position of oil cylinder fixed block 7, make oil cylinder top 6 withstand preventer fluid cylinder flashboard axis, the manual pump pipeline is connected with oil cylinder, through hydraulic way flashboard axis is carried out dismounting under evenly stressed state.
After adopting the utility model, positioning seat can be fixed on the preventer, and jacking cylinder can connect manual pump, through hydraulic oil the jacking cylinder piston rod is ejected, and the oil cylinder top that is connected on the piston rod ejects or head into the preventer fluid cylinder with the ram block axle.Guide pad can be done the front and back position adjustment along guide post, does the adjustment of position, the left and right sides along the oil cylinder backstay, and the oil cylinder fixed block can be done the adjustment of position, the left and right sides along the oil cylinder backstay, and the preventer that can adapt to different size, specification uses.
In order flashboard axis is conveniently, reliable to load and unload; The employing jacking cylinder ejects flashboard axis or packs under evenly stressed state; Jacking cylinder should be fixed on preventer fluid cylinder center, should fix and positioner according to the structural design jacking cylinder of ram preventer for this reason.
When changing flashboard axis, must dismantle the attachment bolt of fluid cylinder head and side door earlier, take off the fluid cylinder head, take off the piston clamp nut again, could flashboard axis be ejected fluid cylinder with jacking apparatus.Different because of ejecting flashboard axis with the flashboard axis direction of packing into, therefore should on preventer, select different anchor points to position.When ejecting flashboard axis, guide post connects screw with the fluid cylinder head and is connected and fixed; When packing flashboard axis into, can guide post be fixed on side door screwing through hole place.The guide pad of positioner, the equal adjustable position of oil cylinder fixed block are adjusted according to the fluid cylinder of different size, and the ram preventer that can adapt to different model uses.
