Embodiment
With reference to Fig. 1-4, reducing leakage magnetic detection device in a kind of petroleum pipe line, by existing flux leakage detector, is connected with delivery device, opposite side connection guiding mechanism 10 in a side of flux leakage detector 9.This delivery device is to promote mainly oil cylinder 6 coaxial being fixed with of oil cylinder seat 3, be intervally distributed with 4 locked cylinders 1 at oil cylinder seat 3 peripheral radials, be fixed with arc sole 2 in the end of each locked cylinder 1, on arc sole 2 outer arcuate faces, be provided with friction disc 11 or card tooth 11.Fix 4 elastic telescopic bracing frames 5 at the cylinder barrel neighboring spaced radial of promoting mainly oil cylinder 6.Be fixed with universal wheel 4 in the outer end of each elastic telescopic bracing frame 5, be fixed with driving-disc 8 at the piston rod front end of promoting mainly oil cylinder 6, driving-disc 8 is connected with flux leakage detector 9.Cylindrical shell 10.12 in the middle of guiding mechanism 10 comprises, the circumferential multiple parallelogram diameter changing mechanisms that distribute in axially upper edge of cylindrical shell 10.12; Each parallelogram diameter changing mechanism comprises the forward and backward bearing 10.9 that is separately fixed at cylindrical shell 10.12 two ends, and on forward and backward bearing 10.9, torsion spring 10.8 is installed in the hinged front and rear connecting rods 10.7,10.1 of difference and hinged place; The end of front and rear connecting rods 10.7,10.1 is hinged with cross bar 10.2 respectively, and roller 10.6 is installed by wheel shaft 10.5 in hinged place.On cross bar 10.2, be also provided with the contact 10.4 of protrusion, the correspondence position in the outside of cylindrical shell 10.12 is provided with touching switch 10.11, and touching switch 10.11 is connected with the pressure out-of-limit alarming device 10.10 in cylindrical shell 10.12.
The use procedure of this device is: oil cylinder seat 3 is connected with external hydraulic oil pipeline and control gear, after flux leakage detector 9, guiding mechanism 10 and delivery device three parts are coaxially connected, on elastic telescopic bracing frame 5, after four universal wheels 4 and guiding mechanism 10 actings in conjunction, whole device is limited on the axis of detected pipeline 7; Start locked cylinder 1, arc sole 2 and pipe friction locking, promote mainly oil cylinder 6 in startup, promotes flux leakage detector 9 and guiding mechanism 10 and move ahead, simultaneously flux leakage detector 9 startup work.Reach after extension limit when promoting mainly oil cylinder 6, starting locked cylinder 1 at this shrinks, arc sole 2 is removed and tube wall effect, startup is promoted mainly oil cylinder 6 and is shunk, the now rubbing action with tube wall at guiding mechanism 10, drive oil cylinder seat 3 to move ahead together with locked cylinder 1, reach after shrinkage limit when promoting mainly oil cylinder 6, again carry out last round of operation.So alternately, advance in the front and back of finishing device in pipeline.Reducing process is as follows: in the time that guiding mechanism enters pipeline, before the torsion of torsion spring 10.8 makes, back link 10.7, 10.1 cross bar 10.2 supportings are got up, roller 10.6 with inner-walls of duct against, while running into obstacle, the angle that roller 10.6 advances changes, cause front rod 10.7, back link 10.1 poses change, torsion spring 10.6 rotates simultaneously, parallelogram diameter changing mechanism deforms and adapts with the inwall of pipeline, because torsion spring 10.8 rotates the torsion producing, roller 10.6 is resisted against on inner-walls of duct all the time, thereby make roller 10.6 be crossed pipeline obstacle place, after cross at pipeline obstacle place, torsion spring 10.8 turns round, and whole device returns to form.In the time need to measuring the pipeline of other diameter, torsion spring 10.8 regulates front rod 10.7, back link 10.1 poses automatically, can realize significantly reducing; In like manner elastic telescopic bracing frame 5 is owing to having the flexible kinetic energy (such as realizing by spring in inside) of automatic contraction, and it can recline with tube wall from main regulation length by obstacle time equally all the time, thereby by pipeline obstacle place.
Prevent the damage of equipment, the height of contact 10.4, and adjust as required with the relative position of touching switch 10.11, 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, and flux leakage detector 9 is rigid in causing device damage; After contact 10.4 contacts with touching switch 10.11, pass to pressure out-of-limit alarming device 10.10 by signal, pipe detector stops both can temporarily halt.
