Embodiment
A preferred embodiment of the present utility model is: referring to Fig. 1, Fig. 2 and Fig. 3, this pipeline log arrangement comprises the mechanism 7 that has the records of distance by the log, pressing mechanism 5, traction coupling assembling 14 and frame 13.The described mechanism 7 that has the records of distance by the log is made up of a pair of wheel 9, driving tooth axle 10, subdivision gear 15, subdivision tooth axle 11 and the scrambler 6 of having the records of distance by the log.Driving tooth axle 10, subdivision gear 15, driven tooth axle 11 are the identical cross helical gear of sense of rotation.Driving tooth axle 10 both sides respectively are equipped with the wheel 9 of having the records of distance by the log.Subdivision gear 15 is enclosed within on the driven tooth axle 11, is coupled as one with torsion spring 16 after the plurality of teeth that staggers, and with 10 engagements of driving tooth axle, driven tooth axle 11 also is connected by holding screw 12 and scrambler 6 simultaneously.Described pressing mechanism 5 comprises support 18, adjusting lever 19, stage clip 21, adjusts wheel 20.Whole pressing mechanism 5 links to each other with frame 13 by screw 22.Described traction coupling assembling 14 comprises coupling shaft 1, rolling bearing 2, adapter sleeve 3 and contiguous block 4.Coupling shaft 1 is used for linking to each other with other devices, and bears the tractive force that adds.Coupling shaft 1 cooperates with the inside and outside circle of bearing 2 respectively with adapter sleeve 3, thereby can produce relative rotation.Contiguous block 4 is in order to connect adapter sleeve 3 and frame 10.
The principle of work of this log arrangement is as follows:
When log arrangement is in the pipeline, referring to Fig. 1, the adjustment wheel 20 in the pressing mechanism 5 is pressed on the tube wall at top, and stage clip 21 is subjected to force compresses, the pressure that produces is transferred on the wheel 9 of having the records of distance by the log by frame 13, driving tooth axle 10, and the wheel 9 of having the records of distance by the log tightly is pressed on the tube wall of bottom.When log arrangement is subjected to outside tractive force and when advancing, has the records of distance by the log wheel 9 under the friction force effect, make pure rolling along pipeline, and drive driving tooth axle 10 and just changeing.Driving tooth axle 10 and follower gear 11 engagements are just changeing thereby drive subdivision tooth axles 15 by torsion spring 16, and finally drive scrambler 6 and be rotated in the forward counting.When log arrangement is subjected to reverse tractive force and when retreating, the wheel 9 of having the records of distance by the log drives 10 counter-rotatings of driving tooth axles.10 direct and subdivision tooth axle 15 engagements of driving tooth axle drive scrambler 6 countings in reverse.When finishing, the count value of scrambler 6 be multiply by an equivalents that is directly proportional with wheel 9 diameters of having the records of distance by the log, promptly obtain having the records of distance by the log and take turns 9 distance values of passing by when having the records of distance by the log.
When internal diameter of the pipeline changes, the pressure that is applied on the stage clip 21 by adjustment wheel 20 and adjusting lever 19 can change, the length of stage clip 21 also changes thereupon, drive adjusting lever 19 and slide up and down along the chute in the support 18, thereby the size of adjustment log arrangement is to adapt to the variation of internal diameter of the pipeline.
The tractive force that is subjected to when the coupling shaft 1 of traction in the coupling assembling 14 comprises a tangential component, or is subjected to an external torque and does the time spent, because coupling shaft 1 can rotate freely with adapter sleeve 3, the moment of torsion that adds just can not be passed on the frame 13.So just can prevent that log arrangement from because of being subjected to additional torque whole phenomenon of rotating around conduit axis taking place, and guarantees to have the records of distance by the log and takes turns 9 all the time along straight ahead, thereby improved the precision of having the records of distance by the log.In addition, if log arrangement rotates because of other reasonses such as vibrations, under the effect of gravity, log arrangement also can rotate around the center by adapter sleeve 3, to be returned to vertical position.
