Description
Technical field
The utility model relates to a kind of oil and builds blowout hookup, particularly a kind of oilfield construction blowout prevention storage and transportation apparatus.
Background technology
Blowout hookup is the requisite wellhead assembly of swabbing operation, and the quality of its sealing performance directly has influence on safety and environmental protection, green construction.At present, because blowout hookup sealing effectiveness is bad, cause environment pollution in pumping process, pollute reparation cost very high, run counter to civilized construction standard, damage the corporate image, therefore the meeting that situation is serious causes stopping work.Although the blowout hookup of onsite application has multiple, all there is such-and-such problem, can not meet construction requirement, therefore, research affects the factor of blowout hookup sealing effectiveness, effectively solves the blowout prevention in pumping process, anti-pollution problem is very necessary.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oilfield construction blowout prevention storage and transportation apparatus.
Its technical scheme is: comprise double jets righting mechanism, hydraulic mechanism, cartridge, wire rope be fixed on the pullover inside of safety, described wire rope is provided with double jets righting mechanism, described double jets righting mechanism comprises front righting wheel and rear righting wheel, wire rope enters hydraulic mechanism inside by front righting wheel, wire rope connects clamping sleeve, cartridge, packing element fixture block, the end of wire rope is fixed by rear righting wheel, described front righting wheel is fixed on the pullover inside of safety, safety is pullover by resetting-mechanism connecting fluid press mechanism, described resetting-mechanism comprises return spring holder joint, return spring holder, back-moving spring overcoat, back-moving spring, return spring holder joint is fixed on return spring holder, described return spring holder connects back-moving spring overcoat, the inside of back-moving spring overcoat is provided with back-moving spring.
Above-mentioned safety is pullover to be connected by shear pin.
Above-mentioned packing element fixture block is that arc ellipse gets stuck structure.
Above-mentioned cartridge is provided with two, and two cartridge are connected by packing element fixed block.
The beneficial effects of the utility model are: adopt double jets righting mechanism to efficiently solve because overhead traveling crane center and well head are not easy the wire rope eccentric wear cartridge problem that centering causes, wire rope changes over rolling friction when going out well head by original bias friction, so namely, improve sealing reliability, extend again blowout hookup packing element application life, also greatly reduce the wearing and tearing of wire rope.Adopt the measures such as high elasticity abrasion-proof packing element, two-stage sealing.In packing element, add wear-resistant filler, increase elasticity and intensity, improve packing element application life.Twin-stage packing element seals, and seal section is lengthened, and sealing effectiveness can be better, and because release mechanism adopts shear pin, avoid due to when the wearing and tearing of wire rope mark are unclear or driller handles error, the accident that wire rope is broken in lower contact encountered by pumping instrument.If this occurs, now shear pin is cut off, and pumping instrument can propose well head safely with blowout hookup, and equipment and personal safety accident can not occur.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of resetting-mechanism;
In upper figure: wire rope 1, safety are pullover 2, front righting wheel 3, rear righting wheel 4, clamping sleeve 5, cartridge 6, packing element fixture block 7, resetting-mechanism 8, hydraulic mechanism 9, packing element fixed block 10, return spring holder joint 8.1, return spring holder 8.2, back-moving spring overcoat 8.3, back-moving spring 8.4.
Detailed description of the invention
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises double jets righting mechanism, hydraulic mechanism, cartridge 6, the inside being fixed on safety pullover 2 of wire rope 1, described wire rope 1 is provided with double jets righting mechanism, described double jets righting mechanism comprises front righting wheel 3 and rear righting wheel 4, it is inner that wire rope 1 enters hydraulic mechanism 9 by front righting wheel 3, wire rope 1 connects clamping sleeve 5, cartridge 6, packing element fixture block 7, the end of wire rope 1 is fixed by rear righting wheel 4, described front righting wheel 3 is fixed on the inside of safety pullover 2, safety pullover 2 is by resetting-mechanism 8 connecting fluid press mechanism 9, described resetting-mechanism 8 comprises return spring holder joint 8.1, return spring holder 8.2, back-moving spring overcoat 8.3, back-moving spring 8.4, return spring holder joint 8.1 is fixed on return spring holder 8.2, described return spring holder 8.2 connects back-moving spring overcoat 8.3, the inside of back-moving spring overcoat 8.3 is provided with back-moving spring 8.4.
Wherein, safety pullover 2 is connected by shear pin; Described packing element fixture block 7 to get stuck structure for arc ellipse; Described cartridge 6 is provided with two, and two cartridge 6 are connected by packing element fixed block 10.
This oilfield construction blowout prevention storage and transportation apparatus adopts double jets righting mechanism by the righting placed in the middle by force of two groups of righting rollers, guarantees that in pumping process, wire rope opposing seal packing element is placed in the middle.Wire rope enters hydraulic cylinder inside by front righting wheel, through clamping sleeve, cartridge, packing element fixture block, after righting wheel, lower band pumping instrument enters the oil pipe be connected with production tree.When transferring wire rope, Pneumatic valve conducting, airdraulic actuator is forced to be in reset mode, power source pressure release, due to the elastic force of spring, hydraulic cylinder is descending, gas-liquid conversion equipment oil cylinder got back to by hydraulic oil, cartridge keeps passive state, avoids and wire rope friction, thus improves the application life of cartridge.When on carry wire rope to fast fluid time, some liquid just brings out with wire rope or sprays in the air from the gap between cartridge and wire rope, is scattered on well site, pollutes.Low pressure is converted to high hydraulic pressure by gas-liquid pressure conversion equipment, and hydraulic oil press-in hydraulic cylinder, promotes hydraulic cylinder up, crush seal packing element, cartridge holds wire rope tightly, like this, both the profit on wire rope can have been wiped off, again can sealing wellhead, prevent profit from spraying.
