Description
Technical field
The utility model is the equipment for dismantling oilfield oil well wellhead assembly, is a kind of oil-water well well head attaching nut disassembly
Device.
Background technique
The oil-water well wellhead assembly in oil field is connected on four-way by bolt group, when oil-water well operation, needs to dismantle bolt group
On attaching nut, separate wellhead assembly with four-way.The oil-water well wellhead assembly in oil field is in field, cannot use existing
The machine tool of nut is dismantled, therefore, the attaching nut in demounting bolt group can only be with traditional spanner by manually carrying out at present
Disassembly, the large labor intensity of operating worker, working efficiency are low.Since the oil-water well wellhead assembly in oil field is in field, there is wind
It drenches with rain, gets rusty between nut and bolt serious, mutual disassembly's nut is more difficult.
Summary of the invention
The purpose of this utility model is to design a kind of oil-water well well head attaching nut's provision for disengagement, overcomes above-mentioned ask
Topic can be carried out mechanization disassembly well head attaching nut, reduce the labor intensity of operating worker, improve working efficiency.
Purpose of the utility model is realized as follows: include support sleeve connecting plate, support tube, left support set, hoop,
Tube, right support set, sleeve, nut, wellhead assembly, four-way, wellhead assembly are connected on four-way by nut, wellhead assembly it is upper
There is hoop in portion, there is internal screw thread in hoop, and the lower part of support tube and the internal screw thread of hoop connect, and sleeve is mounted on tube
Lower part, sleeve can entangle nut and drive its rotation, and left support set, right support set are linked into an integrated entity by support sleeve connecting plate, left branch
Support set is sleeved on support tube, and left support set can rotate about the axis thereof on support tube, and tube passes through right support set, right support set
The sleeve of lower part entangles nut.
The beneficial effects of the utility model are: tube is manufactured by well oil pipe, it can use and be used for connected pipes spiral shell on operation well
The hydraulic tongs of line encase tube, and the hydraulic coupling on working rig disassembles nut when driving tube rotation, the utility model
Existing equipment on operation well is utilized, mechanization disassembly is carried out to nut, can be reduced the labor intensity of operating worker, improve work
Make efficiency, there is significant economic benefit and social benefit.
Detailed description of the invention
Fig. 1 is the installation diagram of the utility model.
Specific embodiment
1 pair of the embodiments of the present invention is illustrated with reference to the accompanying drawing.
As shown in Figure 1, the embodiments of the present invention include support sleeve connecting plate 1, support tube 2, left support set 3, clip
First 4, tube 5, right support cover 6, sleeve 7, nut 8, wellhead assembly 9, four-way 10, and wellhead assembly 9 is connected to four-way 10 by nut 8
On, hoop 4 is arranged at the top of wellhead assembly 9, there is internal screw thread, generally 2 in hoop 47/8TBG tubing round thread, support tube 2
Screw thread identical with 4 internal screw thread of hoop is arranged at lower part, and the lower part of support tube 2 is connect with the internal screw thread of hoop 4, and sleeve 7 is installed
In the lower part of tube 5, sleeve 7 can entangle nut 8 and drive its rotation, and nut 8 is outer-hexagonal shape, and sleeve 7 is just interior hexagon, left
Support sleeve 3, right support set 6 are linked into an integrated entity by support sleeve connecting plate 1, and left support set 3 is sleeved on support tube 2, left support set 3
It can be rotated about the axis thereof on support tube 2, tube 5 passes through right support set 6, and the sleeve 7 that right support covers 6 lower parts entangles nut 8.
Four-way 10 is referred to as big four at the scene.Left support set 3 can slide axially on support tube 2, to adjust difference
Well head height.Tube 5 is 27/8TBG oil pipe can match with the hydraulic screw-on machine at scene.The length of tube 5 is by live hydraulic screwing
The height of deduction determines, can length can not be short.
Wellhead assembly 9, four-way 10 are to be linked together by ring flange with multiple nuts, these nuts are distributed in concentric
Circumference on, the axis of support tube 2 after dismantling a nut with hydraulic screw-on machine (hydraulic tongs), then rotates the right side on this center of circle
Support sleeve 6, the sleeve 7 of 5 lower part of tube, which can be gone at another nut, dismantles it.
