Description
Technical field
The equipment when present invention is boll-weevil hanger under oil field operation, specifically boll-weevil hanger erection device.
Background technology
Entering down hanger during oil field oil water well operations and be suspended on the big four of wellhead assembly by OIH pipe, hanger also to play the effect of Seal Oil sleeve pipe, makes the highly pressurised liquid of more than hanger can not leak in sleeve pipe, therefore, hanger has sealing ring.Hanger under enter in process will through preventer, due to derrick tilt to cause hanger can not honest under enter, often there is the problem that the sealing ring on bad hanger hung by the flashboard in preventer.In order to solve hanger under enter sealing ring in process and hung bad problem, it is promote, from deflection one direction the opposing party, the oil pipe being connected to hanger with manpower at the scene, but Manual-pushing is not only wasted time and energy, uncertain hanger can be made placed in the middle, and operator to bow observation near well head, burst accident can not be hidden, there is potential safety hazard.
Summary of the invention
It is an object of the invention to design a kind of boll-weevil hanger erection device so that it is enter under hanger and will not hang bad sealing ring and easy, safety through preventer, time saving and energy saving.
The object of the present invention is achieved like this: includes promoting oil pipe, sealing ring, hanger, preventer, connecting bolt, sealing ring is arranged on hanger, promote oil pipe bottom to be connected with hanger, OIH pipe is connected under hanger, also include roller, wheel carrier, support, base, support bar, adjusting screw rod, supporting seat, base is fixed on preventer by connecting bolt, base has rail groove, the right flank of base has screw, the female thread of this screw is supporting with the external screw thread of adjusting screw rod, adjusting screw rod is from the right flank screw of base through rear injection groove, supporting seat is sleeved on the left end of adjusting screw rod, supporting seat is in rail groove, the lower end of support bar and supporting seat hinge connection, the bottom hinge connection of the upper end of support bar and support, the lower end of support and base hinge connection, wheel carrier is arranged on the top of support, wheel carrier is installed roller, roller is near the outside promoting oil pipe.
Roller surface is provided with arc-shaped slot, and the radius of arc-shaped slot is identical with the radius promoting oil pipe.
The right flank screw screw thread of adjusting screw rod external screw thread and base is rectangular thread, and pitch is 4-6mm.
The invention has the beneficial effects as follows: rotate adjusting screw rod, lifting oil pipe can be promoted to be at the bosom position of preventer, will not with the rams contact in preventer when entering under hanger by preventer, sealing ring on hanger will not be hung bad, ensure to construct successfully, operation is avoided to do over again, rotate adjusting screw rod just energy righting hanger, easy, quick, time saving and energy saving, near well head, need not will not there is security incident in operator, therefore, the present invention has significant economic benefit and social benefit.
Accompanying drawing explanation
Accompanying drawing 1 is the installation diagram of the embodiment of the present invention.
Accompanying drawing 2 is the top view of part 2 in accompanying drawing 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are illustrated.
As seen from the figure, embodiments of the invention include promoting oil pipe 1, roller 2, wheel carrier 3, support 4, sealing ring 5, hanger 6, preventer 7, connecting bolt 8, base 9, support bar 10, adjusting screw rod 11, supporting seat 13, sealing ring 5 is arranged on hanger 6, promote oil pipe 1 bottom to be connected with hanger 6, OIH pipe traverse preventer 7 is connected under hanger 6, base 9 is fixed on preventer 7 by connecting bolt 8, base 9 has rail groove 11, the right flank of base 9 has screw, the female thread of this screw is supporting with the external screw thread of adjusting screw rod 12, adjusting screw rod 12 is from the right flank screw of base 9 through rear injection groove 11, supporting seat 13 is sleeved on the left end of adjusting screw rod 12, supporting seat 13 is in rail groove 11, supporting seat 13 can only be walked in rail groove 11 and can not be rotated, the lower end of support bar 10 and supporting seat 13 hinge connection, the bottom hinge connection of the upper end of support bar 10 and support 4, the lower end of support 4 and base 9 hinge connection, wheel carrier 3 is arranged on the top of support 4, wheel carrier 3 is installed roller 2, roller 2 can rotate on wheel carrier 3, roller 2 is near the outside promoting oil pipe 1.Roller 2 surface is provided with arc-shaped slot 14, and the radius of arc-shaped slot 14 is identical with the radius promoting oil pipe 1, in order to be fully contacted with promoting oil pipe 1, and do not wear and tear lifting oil pipe 1.
The external screw thread of adjusting screw rod 12 and the right flank screw screw thread of base 9 are rectangular thread, and pitch is 4-6mm, and rectangular thread transmission moment is big, and the big walking of pitch is fast, and passage is fast.
The side of hanger 6 skewed is in when being arranged on preventer 7 by base 9, rotate adjusting screw rod 12, adjusting screw rod 12 is walked, supporting seat 13 can not rotate in rail groove, but can walk together with adjusting screw rod 12, makes support bar 10 lower end together walk, make the roller 2 on support promote and promote oil pipe 1 to center position, then transferring lifting oil pipe 1, make hanger 6 pass through preventer 7, the sealing ring 5 on hanger 6 will not be hung bad by the flashboard in preventer 7.Promote when oil pipe 1 is transferred and roller 2 is rolling friction, can along unobstructed descending.
