In the support arm circular hole of baffle upper and lower ends, then in guide rail bracket guide rail, and using limited block to limit roller
With baffle guide rail bracket radial direction moving range.Spring is mounted between baffle and guide rail bracket, to ensure that baffle and oil pipe can begin
Terminating is touched, and spring is in compressive state always during the work time.Baffle inner wall has hemispherical projections, to ensure baffle and oil pipe
After contact, there is certain interval between baffle and oil pipe；Inclined circular hole is provided on baffle, for installing fluid jet nozzle.It leads
There are hydraulic line channels in rail gantry, so that hydraulic line passes through.After diameter changing mechanism installs shell, baffle can be straight according to oil pipe
Diameter moves radially, and realizes the opening and closing of movement, to realize reducing function.
Compared with the prior art, the utility model has the following advantages：
1, 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.
2, entire cleaning process carries out while playing pipe, will not increase additional cleaning, work efficiency is high.
3, the cleaning process of oil pipe carries out in the device, and cleaning waste liquid is discharged by drain pipe, facilitates at the concentration of waste liquid
Reason, avoids pollution of the waste liquid to well site environment.

Specific implementation mode
The utility model is described further 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 drain
Pipe 1, shell 2, movement 3, fluid jet nozzle 4, water-supply-pipe 5, pressing plate 6, end cap 7.1 structure of drain pipe is three-port structure, upper port weldering
It is connected on shell 2, lower port is connect by ring flange with wellhead assembly, and 1 central port of drain pipe passes through method for waste liquid to be discharged
Blue disk is connected with waste solution channel.
Movement 3 is made of three diameter changing mechanisms 30, and diameter changing mechanism 30 presses circumferential arrangement, and mutual angle is 120 °,
In shell 2.Diameter changing mechanism 30 is that dovetail groove is connect with 2 connection type of shell, and the protrusion of diameter changing mechanism 30 can just pacify
The groove for putting into shell 2, with being combined into clearance fit.After diameter changing mechanism 30 installs 2 groove of shell, corresponding pressing plate 6 is installed, when
After three groups of diameter changing mechanisms 30 and pressing plate 6 are respectively mounted shell 2, end cap 7 is finally installed, to limit the axial freedom of diameter changing mechanism 30
Degree.
As shown in Fig. 4, Fig. 5, Fig. 6, diameter changing mechanism 30 is by baffle 301, guide rail bracket 302, spring 303, limited block 304 and rolling
Column 305 forms.The upper and lower ends of baffle 301 are respectively there are one support arm, the bore inner diameter on support arm and 305 outer diameter size of roller
Equal, roller 305 is installed is combined into clearance fit into matching for support arm.For 302 upper and lower ends of guide rail bracket respectively there are one guide rail, guide rail is wide
Degree is more slightly larger than 305 outer diameter of roller.301 support arm of baffle, roller 305 and 302 guide rail of guide rail bracket form 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, to limit
Moving range of the baffle along 301 guide rail, 302 frame radial direction.302 middle part of guide rail bracket is equipped with cylindrical pit, 301 middle part welding of baffle
