Description
Technical field
The utility model belongs to marine oil installations technical field, relates to a kind of marine drilling platform blowout preventer unit and hangs the instrument of moving.
Background technology
Blowout preventer unit is the key equipment in well-control equipment, and blowout preventer unit comprises the parts such as annular preventer, ram preventer, four-way and valve, ensures carrying out smoothly and personal safety of drilling operation.Self-lifting type marine drilling platform uses blowout preventer unit waterborne, needs blowout preventer unit to hang from the storage area entirety divided to move to pithead position and install when installation, or after dismounting, entirety shifts out well head, and disassemble and assemble work amount is large.
Existing movement mode adopts chain or steel rope, by the lifting otic placode on lifting device, blowout preventer unit is lifted by crane and movement, due to marine drilling platform blowout preventer unit weight greatly, highly high, this lifting mode can not ensure the stationarity of lifting and movement, and lifting device rigidity of structure relative deficiency when movement large-tonnage blowout preventer unit, there is potential safety hazard, have impact on work efficiency.
Utility model content
The purpose of this utility model is to provide a kind of marine drilling platform blowout preventer unit and hangs the instrument of moving, solve in prior art and adopt chain or steel rope, by the lifting otic placode on lifting device, blowout preventer unit is lifted by crane and movement, stationarity is poor, there is potential safety hazard, have impact on the problem of work efficiency.
The technical scheme that the utility model adopts is, a kind of marine drilling platform blowout preventer unit hangs the instrument of moving, and comprises two centrosymmetric semicircular ring, and the joint of these two semicircular ring is fixedly connected with by many cover bolt assemblies; Be symmetrically arranged with middle cone in the middle part of two semicircular ring inwalls, or inwall bottom symmetrical is provided with bottom stage; Two semicircular ring outside faces are provided with a holder ear separately.
Marine drilling platform blowout preventer unit of the present utility model hangs the instrument of moving, and is further characterized in that:
Two semicircular ring outside faces are provided with two paving platform mounting brackets separately, and two semicircular ring tops are respectively equipped with the lifting tapped bore of lifting.
Holder ear is welded by gusset, stay bearing plate and holder handle, and holder handle interlude is semicolumn.
The beneficial effects of the utility model are, solve in existing lifting device to lift not steadily, impact problem that is large, rigidity of structure relative deficiency, decrease disassemble and assemble work amount simultaneously, maintain easily, increase work efficiency, specifically comprise:
1) tie bolt is near holder ear, bolt strained little, can hang and move large-tonnage blowout preventer unit;
2) rigidity of structure is high, and by arc surface and the hanging apparatus rigid contact of holder handle interlude, do not adopt chain or steel rope, when operation, live load is less, achieves steadily and relative fast speed hangs and moves;
3) this hangs after the instrument of moving is arranged on annular preventer and just need not dismantle, and lifting and movement conveniently, decrease disassemble and assemble work amount, improve work efficiency;
4) paving platform mounting bracket is provided with, for installing paving platform and fence, the convenient detection to blowout preventer unit and handling labor.
Accompanying drawing explanation
Fig. 1 is the axonometric drawing that the utility model hangs the instrument of moving;
Fig. 2 is the semicircular ring axonometric drawing that the utility model hangs in the instrument of moving;
Fig. 3 is the birds-eye view that the utility model hangs the instrument of moving.
In figure, 1. semicircular ring, 2. bolt, 3. packing ring, 4. nut, 5. hold in the palm ear, 6. spreads platform mounting bracket, 7. middle cone, 8. bottom stage, 9. lifts tapped bore.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, structure of the present utility model is, comprise two centrosymmetric semicircular ring 1, the joint (flange mounting edge) of these two semicircular ring 1 is fixed together by many cover bolt assemblies, often overlaps bolt assembly and comprises bolt 2, packing ring 3 and nut 4 thereof;
Be symmetrically arranged with middle cone 7 in the middle part of two semicircular ring 1 inwalls, or inwall bottom symmetrical is provided with bottom stage 8, have the conical surface to meet surface or do not have the support of the annular preventer of the conical surface to coordinate;
A holder ear 5 and two paving platform mounting brackets 6 are provided with separately at two semicircular ring 1 outside faces; Holder ear 5 is welded by gusset, stay bearing plate and holder handle, and holder handle interlude is semicolumn, and the arc surface of semicolumn is as the contact site with board migration device;
The lifting tapped bore 9 of lifting is had at two semicircular ring 1 tops;
Above-mentioned all parts, by adjust size, can realize hanging of different size blowout preventer unit and move.
Principle of work of the present utility model is,
Because the manufacturer of annular preventer is different, its contour structures and size be corresponding difference also, according to the contour structures of annular preventer, middle cone 7 can be selected to support the weight of whole blowout preventer unit, also bottom stage 8 can be selected as bearing surface, hold the weight of whole blowout preventer unit; Two semicircular ring 1 respectively have one to hold in the palm ear 5 and two paving platform mounting brackets 6, and paving platform mounting bracket 6 is used for installing paving platform and fence, the convenient detection to blowout preventer unit and handling labor, and lifting tapped bore 9 is arranged at top, is used for installing hanger, conveniently hangs hanging of the instrument of moving and move;
The arc surface of the semicolumn in holder ear 5 is as the contact site with board migration device, and this position held by the pallet of blowout preventer board migration device, hangs accordingly move blowout preventer unit; Angle requirement between holder ear 5 longitudinal plane of symmetry and semicircular ring face of joint: when ensureing that tie bolt is not interfered with the pallet of board migration device, as far as possible near holder ear central axis, can reduce the stressed of bolt; Held the holder handle of ear 5 by the pallet of blowout preventer board migration device, realize the lifting to whole blowout preventer unit and movement.
The utility model has the advantages that, with transportation equipment rigid contact, ensure that the stationarity of hanging and moving, the rigidity of structure is high, and disassemble and assemble work amount is little, strong adaptability, and is provided with paving platform mounting bracket, easy to maintenance.
