In the support arm circular hole of baffle plate upper and lower ends, then in guide rail bracket guide rail, and using limited block to limit roller
With baffle plate guide rail bracket radial direction moving range.Spring is arranged between baffle plate and guide rail bracket, to ensure that baffle plate and oil pipe can begin
Terminating is touched, and spring is in compressive state all the time in the course of the work.Baffle inner wall has hemispherical projections, to ensure baffle plate and oil pipe
After contact, there is certain interval between baffle plate and oil pipe；Inclined circular hole is provided with baffle plate, for installing fluid jet nozzle.Lead
Hydraulic line passage is left in rail gantry, so that hydraulic line passes through.After diameter changing mechanism installs housing, baffle plate can be straight according to oil pipe
Footpath moves radially, and realizes the opening and closing of movement, so as to realize reducing function.
Compared with the prior art, the present invention has advantages below：
1st, using adaptive reducing core arrangement, it can be always ensured that the gap of fluid jet nozzle and oil pipe is in optimum state,
Cleaning performance is good.
2nd, whole cleaning process is carried out while pipe is played, and will not increase extra cleaning, and operating efficiency is high.
3rd, the cleaning process of oil pipe is carried out in device, and cleaning waste liquid is discharged by discharging tube, is facilitated at the concentration of waste liquid
Reason, avoids pollution of the waste liquid to well site environment.

Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of oil pipe well head on-line cleaning device of adaptive reducing of the present invention includes discharge opeing
Pipe 1, housing 2, movement 3, fluid jet nozzle 4, water-supply-pipe 5, pressing plate 6, end cap 7.The structure of discharging tube 1 is three-port structure, and upper port is welded
It is connected on housing 2, lower port is connected by ring flange with wellhead assembly, and the central port of discharging tube 1 is used to discharge waste liquid, passes through method
Blue disk is connected with waste solution channel.
Movement 3 is made up of three diameter changing mechanisms 30, and diameter changing mechanism 30 circumferentially arranges, and mutual angle is 120 °,
In housing 2.Diameter changing mechanism 30 is that dovetail groove is connected with the connected mode of housing 2, and the projection of diameter changing mechanism 30 can just pacify
The groove of housing 2 is put into, is coordinated with gap is combined into.After diameter changing mechanism 30 installs the groove of housing 2, pressing plate 6 corresponding to installation, when
After three groups of diameter changing mechanisms 30 and pressing plate 6 are respectively mounted housing 2, end cap 7 is finally installed, to limit the freedom of the axial direction of diameter changing mechanism 30
Degree.
As shown in Fig. 4, Fig. 5, Fig. 6, diameter changing mechanism 30 is by baffle plate 301, guide rail bracket 302, spring 303, limited block 304 and rolling
Post 305 forms.The upper and lower ends of baffle plate 301 respectively have a support arm, the bore inner diameter on support arm and the external diameter size of roller 305
Equal, roller 305 is installed to be coordinated into support arm with gap is combined into.The upper and lower ends of guide rail bracket 302 respectively have a guide rail, and guide rail is wide
Degree is more slightly larger than the external diameter of roller 305.The support arm of baffle plate 301, roller 305 and the guide rail of guide rail bracket 302 composition rolling bearing.Roller 305
After guide rail bracket 302 is installed, displacement range of the roller 305 in guide rail bracket 302 is limited using limited block 304, so as to limit
Moving range of the baffle plate along the frame radial direction of 301 guide rail 302.The middle part of guide rail bracket 302 is provided with cylindrical pit, and the middle part of baffle plate 301 is welded
There are cylindrical protrusions, spring 303 is between the middle part pit of guide rail bracket 302 and baffle plate 301 are central raised, and spring 303 is in work
All the time compressive state is in during work, to ensure that baffle plate 301 and oil pipe 8 can contact all the time.The inwall of baffle plate 301 has hemispherical convex
Rise, after ensureing baffle plate 301 and the contact of oil pipe 8, have certain interval between baffle plate 301 and oil pipe 8.It is provided with baffle plate 301
Inclined circular hole, for installing fluid jet nozzle 4.Guide rail bracket 302 is provided with the passage of water-supply-pipe 5, facilitates passing through for water-supply-pipe 5.
The assembling sequence of the device is generally：Diameter changing mechanism 30 is assembled first, then installs diameter changing mechanism 30 into shell
Inside body 2, then discharging tube 1 is welded on housing 2, pressing plate 4, fixed end cap 5 are finally installed.
During using the device, device is arranged on above preventer.The device does not possess well blowout preventing function, need to match somebody with somebody with preventer
Close and use.In the course of work, when oil connection begins to pass the device, because the external diameter of oil pipe 8 increases, oil pipe is to baffle plate 301
A thrust can be acted on, the power can be analyzed to thrust vertically and thrust radially, and axial thrust is supported by baffle plate 301
Interaction force between arm, roller 305 and guide rail bracket 302 balances, radial thrust by baffle plate 301 and guide rail bracket 302 it
Between spring 303 elastic force balance.
Change the quantity of diameter changing mechanism 30 in device, so as to change the structure of movement 3；It is clear that the device is applied to sucker rod
Wash, should all regard as in technical scheme.
