Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
The design core of the present invention is to employ advanced circumferential movement analogy method.The present invention being capable of simulated pressure appearance
The circumferential movement of device flange crawl trolley, compared to pressure container flange analogue body, with compact structure, light-weight, adult is low, takes
Band is convenient, is applicable in the advantages that heap-type is more.After crawl trolley is fixed in rack 1, cylinder 9 is stretched out entire roller transmission system top
Onto crawl trolley, crawl trolley driving wheel 10 drives driving roller 3, then drives driven roller 7 by toothed belt transmission, finally
It takes crawl trolley terminal encoder wheel 11 to again to rotate, realizes circumferential analog functuion.
As shown in Figure 1 to Figure 3, the present invention is a kind of pressure container flange crawl trolley circumferential movement simulating bench, including
It is rack 1, idler wheel installing plate 2, driving roller 3, driving roller bearing block 4, synchronous pulley 5, synchronous belt 6, driven roller 7, driven
Roller shaft bearing 8 and cylinder 9；When being debugged to crawl trolley, driving roller 3 is contacted with crawl trolley driving wheel 10, driven
Idler wheel 7 is contacted with crawl trolley terminal encoder wheel 11.
The generally hollow frame structure of rack 1 is the installation foundation part of the present invention.The cylinder body of cylinder 9 is fixedly mounted
In rack 1, the piston of cylinder 9 is connected with idler wheel installing plate 2；Cylinder 9 stretches out, and can drive idler wheel installation version 2 and pacify thereon
The idler wheel ejection of dress.
Two driving roller bearing blocks 4 are fixedly connected with idler wheel installing plate 2, and driving roller 3 passes through a pair of bearings and active
Roller shaft bearing 4 is connected, and can be rotated on driving roller bearing block 4；Two driven roller bearing blocks 8 are solid with idler wheel installing plate 2
Fixed connection, driven roller 7 are connected with driven roller bearing block 8 by a pair of bearings, can be rotated on driven roller bearing block 8.
The position of driving roller 3 and driven roller 7 is narrowly focused towards crawl trolley driving wheel 10 and crawl trolley terminal encoder wheel 11；When
When cylinder 9 stretches out, driving roller 3 is withstood on crawl trolley driving wheel 10, and crawl trolley driving wheel 10 can be passed by friction pulley
It is dynamic that power is transmitted to driving roller 3；When the cylinder of crawl trolley terminal encoder wheel 11 stretches out, crawl trolley terminal encoder
Wheel 11 is withstood on driven roller 7, and driven roller 7 can be transmitted to crawl trolley terminal encoder wheel 11 by frictional wheel drive.
Two synchronous pulleys 5, are fixedly and coaxially connected respectively with driving roller 3 and driven roller 7, two synchronous pulleys 5 with
Synchronous belt 6 forms synchronous belt pair, and driving roller 3 can be moved driven roller 7 by synchronous belt subband and be rotated, and direction is identical.By
Identical with 7 diameter of driven roller in driving roller 3, two 5 numbers of teeth of synchronous pulley are identical, therefore driving roller 3 and driven roller 7
Outer circle linear velocity it is also consistent.
During work, first crawl trolley is fixed in rack 1, after fixed, crawl trolley driving wheel 10 is with actively rolling
Wheel 3, crawl trolley terminal encoder wheel 11 are just aligned with driven roller 7 in short transverse and laterally.Cylinder 9 stretches out, and drives
Entire idler wheel transmission ejection, driving roller 3 are withstood on crawl trolley driving wheel 10, the cylinder of crawl trolley terminal encoder wheel 11
It stretches out on the upper driven roller 7 in top.When crawl trolley is circumferentially debugged, crawl trolley driving wheel 10 is passed power by frictional wheel drive
Power is transmitted to driven roller 7, then crawl trolley is transmitted to by frictional wheel drive to driving roller 3, then by toothed belt transmission
Terminal encoder wheel 11 realizes circumferential analog functuion.
The embodiment of the present invention is explained in detail above, the above embodiment is only most highly preferred embodiment of the invention,
