Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail, but the utility model is simultaneously It is not limited to these embodiments.
As shown in Figures 1 to 4, a kind of pipeline rotation detection robot diameter changing mechanism, including it is arranged symmetrically in rotation detection Support diameter changing device is set on a left side for 14 two sides of device and support diameter changing device is set on the right side, and left and right support diameter changing device of setting is mounted on centre The both ends of axis 19 are attached by jackshaft 19, so that it is guaranteed that the two remains synchronization action during variable diameter.Left, The right side set support diameter changing device include gear fixing body 1, intermediate gear 2, transmission gear 3, gear wheel 4, outer diameter regulating member and It is fixedly mounted with disk 10.There are three transmission gears 3, while being engaged with intermediate gear 2 and gear wheel 4, thus by power the two it Between transmitted.
As shown in figure 1, figure 3 and figure 4, intermediate gear 2, transmission gear 3, gear wheel 4 are arranged in the interior of gear fixing body 1 Portion, intermediate gear 2 are mounted on jackshaft 19, and transmission gear 3 is mounted on the column of 1 inside of gear fixing body, gear installation The inner face of body 1 is connected with disk 10 is fixedly mounted with.
As shown in Figure 1, Figure 3,4 exterior portion of gear wheel is ring gear, is set with the one of thrust bearing 13 on external cylindrical surface A lasso, another lasso of the bearing is arranged in the annular convex platform on 1 medial surface of gear fixing body, to make gear wheel 4 Axial position fixed.Annulus is set in the outer circle of 4 inboard portion of gear wheel, be uniformly distributed on annulus there are three connection Block, it is by link block that gear wheel 4 and connecting rod 5 is hinged.
As Figure 1 and Figure 4, outer diameter regulating member is three groups, with 120 ° of the even angle distribution in space, every group of outer diameter tune Section component includes connecting rod 5, sliding block 9, wheel mount 7, wheel 6 and buffering support rod 8;Connecting rod 5 with certain radian with Prevent the outer profile in rotation process with gear wheel 4 from interfering, its one end and the link block on 4 excircle of gear wheel is mutually cut with scissors Connect, the lateral surface of the other end and sliding block 9 carry out it is hinged;There is elongated boss to be used to and be fixedly mounted on disk 10 on the medial surface of sliding block 9 Radial groove match, end is filled with wheel mount 7, passes through hinge between the lateral surface and wheel mount 7 of sliding block 9 The mode of connecing is also connected with cushioning supportive bar 8;Cushioning supportive bar 8 has elastic element, plays the role of certain buffering absorbing, and make Diameter changing mechanism has certain obstacle climbing ability;The end of wheel mount 7 is welded with a U-shaped component, in the centre of the component It is fixed equipped with wheel 6, and by pin shaft.
As shown in Figure 1 and Figure 2, the main body for being fixedly mounted with disk 10 is disc-shaped structure, has on disk body excircle and is separated by 120 ° Three radial protrusions.Being fixedly mounted with disk 10, radially ecto-entad is followed successively by circumferentially uniformly distributed three through the radial groove of entire protrusion To constrain the mobile route and three sections of circumferentially arcuate notches of sliding block 9.The centre bore for being fixedly mounted with disk 10 is used to install jackshaft 19, Be used to be set with a lasso of thrust bearing 11 between the centre bore and arc-shaped slot for annular convex platform, the bearing it is another A lasso is assemblied in the central stepped of gear wheel 4.
As shown in Figure 1, Figure 2, Figure 4 shows, the main body of gear fixing body 1 is shell type structure, and excircle has uniformly done at three and cut It removes, to prevent from interfering in relative movement with connecting rod 5;There are three spaces each other to be separated by 120 ° on its inner side end Column is machined with positioning shaft shoulder on each column, for positioning to the bearing 12 being mounted in transmission gear 3.Gear The inside curved end of fixing body 1 is attached with disk 10 is fixedly mounted with by screw;Stretch out in the shaft part of 1 outer end face of gear fixing body Other component for diameter changing mechanism to be rotated detection robot with pipeline is attached.
As shown in figure 3, rotation detection device 14 is mounted in by bearing holder (housing, cover) when diameter changing mechanism and detection device are assembled In installation base body 18, the axial position of installation base body 18 is determined by mounting blocks 15.The outer end face of mounting blocks 15 passes through screw It is connected with adapter 17, adapter 17 is connected further through bolt with disk 10 is fixedly mounted with, and then sets support diameter changing device and rotation for left and right Turn detection device 14 to link together.Adapter 17 is the ladder-like disk-shaped structure with centre bore, to prevent from sending out between components Raw interference, has three sections of circumferentially arcuate notches for corresponding with the notch being fixedly mounted on disk 10, also thereon so as at the end of variable diameter Variable diameter lock screw 16 is installed.
When carrying out variable diameter operation in the case where predicting pipe diameter, the position of one of wheel 6 is manually adjusted first, 7 opening angle of wheel mount being attached thereto changes.Due between wheel mount 7 and cushioning supportive bar 8, sliding block 9 Triangular structure is formd, then cushioning supportive bar 8 is compressed or elongated, thus with movable slider 9 along the diameter being fixedly mounted on disk 10 It is slided to sliding slot.Because sliding block 9 and connecting rod 5 are hinged, therefore connecting rod 5 is driven to swing, then gear wheel 4 is driven to rotate.Due to Gear wheel 4 is connected with three groups of outer diameter regulating members, therefore the position of the another two wheel 6 of the side also synchronizes and changes.With This simultaneously, power is transferred to intermediate gear 2 by transmission gear 3 by gear wheel 4, and intermediate gear 2 drives jackshaft 19 to rotate. Then, power is transferred to the intermediate gear 2 in other side support diameter changing device by jackshaft 19, to drive transmission gear 3, big Gear 4 rotates, and connecting rod 5 follows swing, and three sliding blocks 9 is driven to move up and down simultaneously, so that the radial direction of three wheels 6 of the side Synchronous variation occurs for position, until six wheels 6 of the left and right sides are formed by the diameter of theoretical circular diameter Yu detected pipeline It is identical.Finally, being fastened on gear wheel 4 after variable diameter lock screw 16 is passed through adapter 17 and the arc-shaped slot being fixedly mounted on disk 10 On inner face, so that the position of gear wheel 4 be locked.It can be seen that left and right set support diameter changing device movement holding together Step, as long as the position of any one wheel changes, the also synchronous variation of other wheels.
The utility model in addition to for other than rotation detection device, can also be needed with other variable diameter, for joint coating on pipeline with And the rotating device of the operations such as pipeline spraying is used cooperatively.
In the description of the present invention, it should be understood that term " center ", "left", "right", "inner", "outside", The orientation or positional relationship of the instructions such as "upper", "lower" is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of retouching The simplified description stating the utility model and carrying out, rather than the device or element of indication or suggestion meaning must have specific side Position is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
