Fig. 2 is the structural representation of guiding mechanism.
Detailed description of the invention
See figures.1.and.2, a kind of antirust coating in pipeline flush coater with guiding mechanism, its preferred embodiment is by sliding sleeve 1, fixed block 2, locating shaft 3, driving wheel 4, belt or chain 5, air motor 6, pneumatic controller 7, horizontal case 8, high pressure gas pipeline 9, the pipeline 10 of being constructed, guide wheel 11, cross bar 13, paint can 14, siphon pipe 15, check valve 16, nozzle 17, ring pipe 18, annular nozzle fixed mount 19, magnetic valve 20, guiding mechanism 21, back link 22, front rod 23, contact 24, wheel shaft 25, cylindrical shell 26, torsion spring 27, before (afterwards) bearing 28, touching switch 29, pressure out-of-limit alarming device 30 and battery, magnetic valve receiver of remote-control sytem, remote controller composition.
Wherein, the cylindrical shell 26 in the middle of guiding mechanism 21 comprises, the circumferential multiple parallelogram diameter changing mechanisms that distribute in axially upper edge of cylindrical shell 26; Each parallelogram diameter changing mechanism comprise be separately fixed at cylindrical shell 26 two ends before (afterwards) bearing 28, on front (afterwards) bearing 28, respectively torsion spring 27 is installed in hinged front and rear connecting rods 23,22 and hinged place; The end of front and rear connecting rods 23,22 is hinged with cross bar 13 respectively; Guide wheel 11 is installed at the two ends of cross bar 13, and cross bar 13 is provided with the contact 24 of protrusion, and the correspondence position in cylindrical shell 26 outsides is provided with the touching switch 29 that can coordinate with contact 24, and touching switch 29 is connected with the pressure out-of-limit alarming device 30 in cylindrical shell 26; Driving mechanism comprises the sliding sleeve 1 that is fixed on horizontal case 8, is fixed on air motor 6, the locating shaft 3 connecting firmly with air motor 6 on sliding sleeve 8, is connected to the driving wheel 4 of locating shaft 3 outer ends and is connected air motor 6 belt or the chain 5 between driving wheel 4 by fixed block 2; Air motor 6 is connected with the pneumatic controller 7 that is located at one side, and pneumatic controller 7 is connected between high pressure gas pipeline 9 and air motor 6 with two-way electromagnetic valve 20, one way solenoid valves, and another road is connected in annular nozzle.
The further perfect scheme of above-described embodiment: described nozzle and pipeline axial are 60-80
0interior angle.Described pneumatic controller 7 is equipped with battery, receiver of remote-control sytem and remote controller.Here matching used receiver of remote-control sytem, remote controller are existing mature technology, just no longer repeat here; Battery aims at receiver of remote-control sytem and magnetic valve provides power supply.
Described sliding sleeve 1 is that bearing and bearing holder (housing, cover) coordinate; At the neighboring of driving wheel parcel friction material layer.
Its operation principle is: the guide wheel 11 of guiding mechanism is joined with tube wall, limit flush coater stable operation in pipeline.Sliding sleeve 1 coordinates with horizontal case rotation, the motor that makes to connect firmly with sliding sleeve 1, driving wheel are under self gravitation effect, remain and pipeline inner bottom surface frictional fit, when driving driving wheel to rotate by air motor, drive whole device to move forward and backward, thus flush coater is transported to pipeline precalculated position.Then start annular nozzle branch road, the coating in paint can, under check valve effect, sprays under high-pressure air pipe siphonage.While gases at high pressure carry coating and act directly on inner-walls of duct, and flush coater is slowly retreated by gases at high pressure opposition simultaneously, completes the interior spraying operation of whole section of tube wall.In the time that guiding mechanism enters pipeline, the torsion of torsion spring 27 makes front and rear connecting rods 23,22 cross bar 13 supportings, guide wheel 11 with inner-walls of duct against, while running into obstacle, the angle that guide wheel 11 advances changes, cause front rod 23, back link 22 poses to change, torsion spring 27 rotates simultaneously, parallelogram diameter changing mechanism deforms and adapts with the inwall of pipeline, because torsion spring 27 rotates the torsion producing, guide wheel 11 is resisted against on inner-walls of duct all the time, thereby makes guide wheel 11 be crossed pipeline obstacle place; After cross at pipeline obstacle place, torsion spring 27 turns round, and whole device returns to form.。
For preventing the damage of equipment, the height of contact 24, and adjust as required with the relative position of touching switch 29, just can control the deformation extent of parallel-crank mechanism with this, the concavo-convex degree of the excessive or pit of the reducing degree because of inner-walls of duct of preventing, projection is too serious, installs rigid in causing device damage; After contact 24 contacts with touching switch 29, pass to pressure out-of-limit alarming device 30 by signal, whole device just can temporarily halt.
