Description
Technical field
The utility model belongs to petroleum drilling and mining equipment technology field, is the key device in the oil drilling well-control equipment preventer.
Background technology
Preventer is to be installed in the drilling process to prevent one of visual plant that gas blowout accident takes place on the drilling channel, preventer divides flashboard preventer and ring-like preventer two big classes, ram preventer is equipped with flashboard in enclosure interior, about flashboard generally is designed to two, realize merging or separating by hydraulic control, to play the effect of closing or opening well head.Because the needs of drilling technology and maintenance from security standpoint, need regularly open the side door of installing preventer housing both sides and change flashboard, and the switch of side door are to rotate by the articulated mounting that connects housing and side door to realize.Traditional articulated mounting is made up of hinge seat that connects housing and side door respectively and pin, in order to realize closing and breakdown action of flashboard body, traditional product has towards the oilhole of side door internal control flashboard movement in the bearing pin indoor design, the outside of axle is equipped with sealing ring etc., the deficiency of this structure mainly shows three aspects, the one, when axle when being with sealing ring to pack hinge seat into, careless slightlyly promptly can cut bad sealing ring, cause leakage of oil; The 2nd, when opening or closing side door, bearing pin can and then rotate, and downward-sloping under the weight effect of whole side door and oil cylinder, and fragile sealing ring causes hydraulic oil to be revealed; The 3rd, relatively difficulty is safeguarded in the replacing of this form of structure sealing ring.
Summary of the invention
The utility model purpose provides three sections separate type articulated mountings of a kind of ram preventer, and load-bearing and hydraulic pressure are separated, and changes problems such as simple and convenient with the sealing life and the seal that solve hydraulic circuit.
Specifically, three sections separate type articulated mountings of a kind of ram preventer, it is mainly by side door hinge I, side door hinge II, hydraulicefficiency hinge, spring, the hydraulicefficiency hinge joint, the load-bearing hinge, taper roll bearing, hydraulic pressure self-turning mechanism and sealing ring are formed, side door hinge I and side door hinge II are by being bolted on the side door, the load-bearing hinge is by being bolted on the housing, joint pin is respectively side door hinge I then, side door hinge II and load-bearing hinge link together, in the load-bearing hinge taper roll bearing is housed, joint pin is by screw thread and side door hinge I, side door hinge II connects, anterior termination is inserted the interior taper roll bearing of load-bearing hinge and is rotated as the center, and the load-bearing hinge is contained in the weight of carrying whole side door and whole hydraulic cylinder on the preventer housing; Hydraulicefficiency hinge is contained between side door hinge I and the side door hinge II and is bolted on the preventer housing by two, and hydraulicefficiency hinge joint and spring are housed in the hydraulicefficiency hinge, is equipped with respectively radially and end-face seal ring on the hydraulicefficiency hinge joint.
The utility model adopts three sections separate types, is about to the mode that load-bearing separates with hydraulic pressure, prolongs the application life of seal and changes easy to maintenance.

The specific embodiment
As shown in Figure 1: the utility model mainly is made up of side door hinge I1, hydraulicefficiency hinge 3, spring 4, hydraulicefficiency hinge joint 5, load-bearing hinge 6, side door hinge II2, bearing 7, rotating dog 8 and a plurality of hermetically-sealed constructions etc.Side door hinge I1 and side door hinge II2 are by being bolted on the side door, load-bearing hinge 6 is by being bolted on the housing, joint pin 8 links together side door hinge I1, side door hinge II2 and load-bearing hinge 6 respectively then, taper roll bearing 7 is housed in the load-bearing hinge, joint pin 8 is connected with side door hinge I, II by screw thread, the taper roll bearing in the load-bearing hinge is inserted in anterior termination, is rotated as the center.Load-bearing hinge 6 is contained in the weight of carrying whole side door and whole hydraulic cylinder on the preventer housing.Hydraulicefficiency hinge 3 is contained between side door hinge I1 and the side door hinge II2 and by two and is bolted on the preventer housing, hydraulicefficiency hinge joint 5 and spring 4 are housed in the hydraulicefficiency hinge 3, be equipped with respectively radially and end-face seal ring on the hydraulicefficiency hinge joint 5, in the course of the work, spring 4 can compress the hydraulicefficiency hinge joint, making it end face is close on the side door hinge, play the effect of sealing oil circuit, when seal damages leakage of oil or maintaining, two bolts of only need dismantling, take out the hydraulicefficiency hinge joint, the sealing ring that replacing is installed above gets final product.
This new device oil channel structures and flow process are respectively shown in accompanying drawing 1,2, when closing preventer, 1. 2. 3. 4. the hydraulic oil that comes out from control system enter into the hydraulic jack that is connected with side door by oil duct successively through main casing, close the chamber to fluid cylinder and carry out closing motion, the chamber of fluid cylinder unlatching simultaneously hydraulic oil goes out oil return and 8. 7. 6. 5. returns control system to main casing through oil circuit.When opening preventer, 8. 7. 6. 5. the hydraulic oil that comes out from control system entered the unlatching chamber execution breakdown action of the hydraulic jack that is connected with side door successively by oil duct through main casing; Close chamber hydraulic oil oil return simultaneously and 1. 2. 3. 4. return control system to main casing through oil circuit.
Under the foregoing description, the utility model structure can also be made following change according to actual needs, and these changes still belong to the utility model protection domain.Side door hinge I1, side door hinge II2 link to each other with side door, and hydraulicefficiency hinge 3, load-bearing hinge 6 link to each other with the preventer housing.Also can be that side door hinge I1, side door hinge II2 link to each other with spray apparatus shell housing, hydraulicefficiency hinge 3, load-bearing hinge 6 link to each other with side door, the bolt that passes through that also can be independent is connected with housing or side door respectively, can be whole also with housing or side door, profile promptly can be round, also can be cuboid, polyhedron etc.
The hinge rotating dog both can be round, also can be the circumference combination, both can be connected with two side door hinges, load-bearing hinge with bearing 7 by screw thread, also can be connected with other by bolt, and joint pin 8 also can change self-turning mechanism into.
The utility model both can be used on the ram-type blowout preventer, also can be used on the equipment of other revolution switch.
