Lower spring 19 is set with mandrel 3.
The flexible controllable type set tube cleaning tool of the scraper is connected with tubing string；Flushing fluid passes through section under pump function during work
Stream set 14 promotes upper mandrels 4 and lower mandrel 3 overall descending, during this, due to the convex platform 12 and lower convex platform on upper mandrel 4
13 contact connection with upper blade 5 and lower coating blade 6, and convex platform 12 and lower convex platform 13 distinguish tapered, upper blade 5 and lower coating blade 6
Bottom be respectively it is corresponding domatic with convex platform 12 and lower convex platform 13；During upper mandrel 4 is descending by convex platform 12 with
Upper blade 5 and lower coating blade 6 are progressively radially ejected housing 1 and contacted with the casing wall of scraping to be cleaned by boss 13, now in pipe
Instrument integral-rotation in the presence of post, you can scraping cleaning is carried out to sleeve pipe.
The scraper stretches controllable type set tube cleaning tool in cleaning process is carried out to sleeve pipe, passes through determining on rotary sleeve 16
The cooperation of position bar 24 and the positioning tooth 21 of different depth on upper limit set 17, can control the stretching of upper blade 5 and the radial direction of lower coating blade 6
Degree, so as to be cleaned to the sleeve pipe of different tube diameters, it is specially：
Upper mandrel 4 and lower mandrel 3 it is overall it is descending during, Caused by Sloping Surfaces boss 20 on lower limit set 15 with it is upper on rotary sleeve 16
Domatic boss 23 contacts, under the effect of the pressure, by peak glide downwards between Caused by Sloping Surfaces boss 20 and upper domatic boss 23,
During this, rotary sleeve 16 drives lower mandrel 3 to rotate, after pump pressure stops, in the presence of upper spring 11 and lower spring 19, on
Mandrel 4 and the lower integral reset of mandrel 3, thus make the locating rod 24 on rotary sleeve 16 be inserted into V-type locating slot 22 one of them
In positioning tooth 21.Because pump pressure is different, the Caused by Sloping Surfaces boss 20 on lower limit set 15 and the upper domatic boss 23 on rotary sleeve 16
Contact is different, and so as to different by the stroke of peak glide downwards between the two, i.e., upper mandrel 4 and the entirety of lower mandrel 3 turn
Dynamic angle is different, when upper mandrel 4 and lower 3 integral reset of mandrel, causes the locating rod 24 on rotary sleeve 16 to be inserted into difference
V-type locating slot 22 in, thus can control the height that extends radially outwardly of scraper, realize the sleeve pipe progress to different tube diameters size
Cleaning.
When pump pressure continues to increase, by peak glide downwards to minimum point between Caused by Sloping Surfaces boss 20 and upper domatic boss 23
When, after pump pressure stops, in the presence of upper spring 11 and lower spring 19, upper mandrel 4 and the lower integral reset of mandrel 3, this process
In, the termination of locating rod 24 contacts with the shiny surface cell wall of the opposite side of V-type locating slot 22, thus makes rotary sleeve 16 in reseting procedure
Continue to rotate, so that Caused by Sloping Surfaces boss 20 returns back to origination data position with upper domatic boss 23, after suppressing again, you can follow
Ring works.
The cooperation for the positioning tooth that the flexible controllable type set tube cleaning tool of scraper is not waited by locating rod and depth, can control
6 radially-protruding height of scraper 5 and lower coating blade, so as to be cleaned to the sleeve pipe of different tube diameters, solves existing scavenger
Tool in-convenience in use, it is impossible to adapt to mineshaft diameter change the problem of requiring, there is positive dissemination.
