Description
Technical field
The present invention relates to the petroleum machinery maintenance of equipment, the overturn overturn system of preventer of particularly a kind of maintenance and being used to when cleaning.
Background technology
Ram preventer and drilling spool need carry out the upset of 0～90 degree when maintenance or cleaning, the method of using is to utilize lifting appliance in conjunction with manually overturning at present, ram preventer that small-sized weight is lighter and drilling spool overturn and are easier to, but large-scale ram preventer and drilling spool weight are very big, reached at the ten or twenty ton that has, upset is got up not only time-consuming but also require great effort, the cost of equipment such as preventer and drilling spool is very high, some is a foundry goods, careless slightly colliding with of causing can be caused scrapping of entire equipment, security reliability is difficult to guarantee, also be not specifically designed at present the equipment of when maintenance or cleaning, overturn ram preventer and drilling spool, can't guarantee the safety of constructing.
Summary of the invention
The blowout preventer turning system that the purpose of this invention is to provide a kind of jumboes such as ram preventer and drilling spool that can overturn time saving and energy saving, safely and reliably.
Technical solution of the present invention is: it comprises base, load-bearing roll over stand, hydraulic overturn oil cylinder, Hydraulic Station assembly and electric control gear, the load-bearing roll over stand is laterally hinged with on base, push-and-pull load-bearing roll over stand upset that the cylinder body of hydraulic overturn oil cylinder is hinged on the base, the end of its piston rod and load-bearing roll over stand are hinged, the hydraulic overturn oil cylinder is connected with the Hydraulic Station assembly by the hydraulic oil pipeline, and the Hydraulic Station assembly links to each other with electric control gear.
Technique effect of the present invention is: use it can be time saving and energy saving, jumboes such as ram preventer or drilling spool safely and reliably overturn when maintenance or cleaning, both can enhance productivity, and also can guarantee safety in production, it has filled up the blank in a domestic and international preventer maintenance field.
It can intelligence automatic plant equipment such as the overweight large-scale preventer of upset, its reversal rate is very fast, upset once is no more than one minute, has both saved flip-flop transition, and is safe and reliable again; It adopts follow-up sleeve formula two-stage hydraulic oil cylinder push-pull mechanism, and floor space is little, and is easy for installation, saves a large amount of manpower and materials; It has the maltilevel security protection mechanism, and defencive function is complete, uses reliable.
But the present invention's load capacity is no more than 20 tons preventer and drilling spool, and it is carried out the upset of 90 degree, so that check, remove contamination and the pressure testing maintenance.The hydraulic pressure push-pull mechanism is a kind of follower that changes with flip angle, is used to realize the upset to various preventers.The Hydraulic Station assembly is fixed on the base, is used to provide needed high voltage power source.The structure of hydraulic jack is also different with common oil cylinder, adopts the telescopic twin-stage cylinder structure of double acting, both can save the oil cylinder entire length, has improved bending resistance and tensile strength again.Hydraulic control system is finished the functions such as upset of preventer by the push pull maneuver of devices such as electro-hydraulic reversing valve control hydraulic cylinder.Electric control gear has motor overload and phase failure protection function.Accumulator is except can be for system replenishes the hydraulic power source, and also playing has a power failure suddenly in the switching process keeps the required minimum pressure of system, guarantee the safe and reliable function of switching process.Native system uses, operation is very convenient, divides manually and two kinds of control modes of remote control.Under manual control mode, can control the angle and the position of blowout preventer turning arbitrarily, easy and simple to handle.Under remote control mode, upset and the loading and unloading of finishing preventer will be safer, convenient, and the visual field also can be openr.
Description of drawings
Fig. 1 is embodiment of the invention master TV structure figure;
Fig. 2 is embodiment of the invention plan structure figure.
The specific embodiment
As shown in Figure 1 and Figure 2, it comprises base 1, load-bearing roll over stand 2, hydraulic overturn oil cylinder 3, Hydraulic Station assembly 4 and electric control gear 5, load-bearing roll over stand 2 is laterally hinged with on base 1, push-and-pull load-bearing roll over stand 2 upsets that the cylinder body 31 of hydraulic overturn oil cylinder 3 is hinged on the base 1, the end of its piston rod 32 and load-bearing roll over stand 2 are hinged, hydraulic overturn oil cylinder 3 is connected with Hydraulic Station assembly 4 by the hydraulic oil pipeline, and Hydraulic Station assembly 4 links to each other with electric control gear 5.
Load-bearing roll over stand 2 is the L shaped bodies of cross section that linked to each other and constituted by orthogonal first bearing plate 21 and second bearing plate, 22 1 sides.Be connected with reinforcing rib 23, the first bearing plates 21 and second bearing plate 22 between first bearing plate 21 and second bearing plate 22 and be respectively the cavity shape structure that hollow has reinforcing rib, this lightweight construction, the intensity height makes load-bearing roll over stand 2 firm in structure, and supporting power is big.Link to each other with second bearing plate 22 rear and front end on limits of first bearing plate 21 is respectively equipped with two base hinged seats 24 that load-bearing roll over stand 2 and base 1 are hinged mutually on first bearing plate 21 of load-bearing roll over stand 2.
About hydraulic overturn oil cylinder 3 comprises two cylinder bodies be hinged on the base 1, the end of piston rod 32 and the high strength sleeve formula two-stage hydraulic oil cylinder that load-bearing roll over stand 2 is hinged.Strong magnet and the strong magnetic inductor 7 that links to each other with electric control gear 5 are installed on the hydraulic overturn oil cylinder 3.
During upset according to the upset requirement, promptly change horizontal positioned into or transfer vertical placement to by horizontal positioned by vertical placement, start overturn system, control load-bearing roll over stand 2 is in plumbness or level (in fact becoming 5 degree angles with horizontal plane) state, then preventer to be flipped (5～15 tons) is winched on the switching mechanism load-bearing roll over stand 2 with crane, starting flip button (left-handed or dextrorotation) overturns, because hydraulic overturn oil cylinder 3 is the special constructions that adopt the high-strength twin-stage sleeve of bending resistance and tension, therefore when becoming secondary by one-level or becoming the one-level push-and-pull by secondary, position sensor 6 should in time send figure signal and give electric control gear 5, electric control gear 5 can change oil circuit rapidly according to mapping mode control electro-hydraulic reversing valve, make reversal rate guarantee that this overweight load can be in time with the flip angle real-time change, safety, upset puts in place reposefully.Cause situation about descending to take place for overcoming to have a power failure suddenly in the moving or switching process of oil cylinder string that load deadweight may cause because of gravitation stall, hydraulic system has disposed bidirectional hydraulic lock and two accumulators 8, even assurance appearance power failure also can make the reliable upset of preventer put in place or reliably stop rapidly overturning, and keeps its state motionless.When blowout preventer turning put in place, position sensor 6 can send the signal that puts in place rapidly and give electric control gear 5, and rotary manipulation is stopped immediately automatically, prevented operating mistake and had an accident.
