Specific embodiment
The scraper stretch controllable type set tube cleaning tool, it is by housing 1, sleeve 2, lower mandrel 3, upper mandrel 4, upper blade 5 It is formed with lower coating blade 6, upper mandrel 4, thrust bearing A7 and thrust is equipped with by thrust bearing A7 and thrust bearing B8 in housing 1 Spring 11 is set on upper mandrel 4 between bearing B8;Thrust bearing A7 is fixedly connected with housing 1, thrust bearing A7 with it is upper Mandrel 4 is slidably connected, and thrust bearing B8 is slidably connected with housing 1;Thrust bearing B8 is fixedly connected with upper mandrel 4.
Multiple upper pilot holes are evenly equipped on upper 4 corresponding 1 circumference of housing of mandrel, upper blade 5 is housed in upper pilot hole, is above scraped Multiple lower pilot holes are evenly equipped on 1 circumference of housing of 5 one side of knife, lower coating blade 6, upper blade 5 and lower coating blade 6 are housed in lower pilot hole Convex platform 12 and lower convex platform 13 are provided on corresponding upper mandrel 4, convex platform 12 and lower convex platform 13 distinguish tapered, upper blade 5 Bottom with lower coating blade 6 is respectively and 13 corresponding slope surface of convex platform 12 and lower convex platform;Upper blade 5 and lower coating blade 6 by with it is upper The cooperation of boss 12 and lower convex platform 13 is slidably connected with upper mandrel 4;Upper 4 ends screw of mandrel is equipped with throat bushing 14, throat bushing 14 connect with thrust bearing B8.
Lower mandrel 3, lower mandrel 3 are equipped with by thrust bearing C9 and thrust bearing D10 in the housing 1 of upper 4 one side of mandrel It is threadedly coupled between upper mandrel 4;Thrust bearing C9 is fixedly connected with housing 1, and thrust bearing C9 is slidably connected with lower mandrel 3, Thrust bearing D10 is slidably connected with housing 1;Thrust bearing D10 is fixedly connected with lower mandrel 3.
15 are covered equipped with lower limit on lower mandrel 3 between thrust bearing C9 and thrust bearing D10, lower limit covers 15 centers and sets Stepped hole is equipped with, lower limit covers is provided with 3 Caused by Sloping Surfaces boss 20 on the end face of 15 one end.The lower core of thrust bearing D10 one sides Rotary sleeve 16 is fixed on axis 3, upper limit, which is housed, on the lower mandrel 3 of 16 one side of rotary sleeve covers 17;It is provided on upper limit set 17 Centre bore, upper limit covers is provided with 3 V-type locating slots 22, the cell wall of each 22 one side of V-type locating slot in the circumferential end surfaces of 17 one end It is upper stepped to be respectively provided with multiple positioning tooths 21;The cell wall of each 22 opposite side of V-type locating slot is shiny surface.
Rotary sleeve 16 is provided centrally with stepped hole, is provided on the end face of 16 one end of rotary sleeve corresponding with Caused by Sloping Surfaces boss 20 3 upper slope surface boss 23, be provided with and 22 corresponding locating rod 24 of V-type locating slot on the end face of 16 other end of rotary sleeve;It is fixed Position 24 end of bar is tapered.It is mutually movable by the cooperation of positioning tooth 21 and locating rod 24 between upper limit set 17 and rotary sleeve 16 Clamping.
The scraper stretch controllable type set tube cleaning tool lower limit set 15 and upper limit set 17 respectively with housing 1 fix connect It connects, lower limit set 15 and upper limit set 17 are slidably connected with lower mandrel 3, and rotary sleeve 16 is slidably connected with housing 1.
Be fixed with sleeve 2 in the housing 1 of lower 3 end of mandrel, one end of sleeve 2 is equipped with shuttle-type first 18, sleeve 2 it is another End is connected with thrust bearing C9;Lower mandrel 3 is slidably connected with sleeve 2;Under lower limit is covered between 15 and thrust bearing D10 Lower spring 19 is set on mandrel 3.
The scraper stretch controllable type set tube cleaning tool be connected with tubing string;Flushing fluid passes through section under pump function during work Stream set 14 promotes upper mandrels 4 and the whole downlink of lower mandrel 3, during this, due to the convex platform 12 and lower convex platform on upper mandrel 4 13 connect 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 and 13 corresponding slope surface of convex platform 12 and lower convex platform;During upper 4 downlink of mandrel by convex platform 12 under Upper blade 5 and lower coating blade 6 are progressively radially ejected housing 1 and are contacted with the casing wall of scraping to be cleaned by boss 13, at this time in pipe Instrument integral-rotation under the action of column, you can scraping cleaning is carried out to casing.
The scraper stretches controllable type set tube cleaning tool in cleaning process is carried out to casing, 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 6 radial direction of upper blade 5 and lower coating blade Degree, is cleaned so as to the casing to different tube diameters, is specially:
During upper mandrel 4 and the whole downlink of lower mandrel 3, on the Caused by Sloping Surfaces boss 20 and rotary sleeve 16 on lower limit set 15 Upper slope surface boss 23 contact, it is under the effect of the pressure, downward by peak between Caused by Sloping Surfaces boss 20 and upper slope surface boss 23 It slides, during this, rotary sleeve 16 drives lower mandrel 3 to rotate, after pump pressure stops, in the effect of upper spring 11 and lower spring 19 Under, thus upper mandrel 4 and lower 3 integral reset of mandrel make the locating rod 24 on rotary sleeve 16 be inserted into V-type locating slot 22 wherein one In a positioning tooth 21.Since pump pressure is different, the Caused by Sloping Surfaces boss 20 on lower limit set 15 and the upper slope surface on rotary sleeve 16 are convex 23 contact of platform is different, and so as to different by the stroke of peak glide downwards between the two, i.e., upper mandrel 4 and lower mandrel 3 are whole The angle that body rotates is different, when upper mandrel 4 and lower 3 integral reset of mandrel, the locating rod 24 on rotary sleeve 16 is caused to be inserted into In different V-type locating slots 22, the height that extends radially outwardly of scraper is thus can control, realizes the casing to different tube diameters size It is cleaned.
When pump pressure continues to increase, by peak glide downwards to minimum point between Caused by Sloping Surfaces boss 20 and upper slope surface boss 23 When, after pump pressure stops, under the action of upper spring 11 and lower spring 19, upper mandrel 4 and lower 3 integral reset of mandrel, this process In, 24 end of locating rod is contacted with the shiny surface cell wall of 22 opposite side of V-type locating slot, 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 slope surface boss 23, after suppressing again, you can follow Ring works.
Scraper stretches the cooperation of positioning tooth that controllable type set tube cleaning tool do not waited by locating rod and depth, can control 6 radially-protruding height of scraper 5 and lower coating blade, cleans so as to the casing to different tube diameters, solves existing scavenger Have inconvenient to use, it is impossible to adapt to the problem of mineshaft diameter variation requires, there is positive dissemination.
