Under the utility model normal condition, two sleeves it is distant, the profile now outside support frame is smaller, adapts to big
Most less tubing stay tubes, when stay tube is carried out, the first fixture on a dismounting wherein sleeve is hinged with jury strut
Connection, rotating shaft is screwed using spanner or other instruments, and under the interception of the guiding disk, jury strut is in gradually with rotating shaft
Vertical trend, now tubing strut to a certain extent, whne tubing strut degree meet require when, stopping screws rotating shaft, will before
Dismounting is screwed with the aforementioned sleeves of jury strut dismounting, treats the distance of the sleeve and guiding disk, and another sleeve and guides disk
Apart from it is identical when, stopping screw the sleeve, the first fixture on the sleeve is articulated and connected with jury strut, completion stay tube,
It is specific rotating shaft is disassembled from chassis when in use, then directly install internal pressure-resistant experimental rig additional at tubing two ends, start
Experiment.
Guiding described in the utility model is supported by proximal end and is also fixed with length adjustment support by fastener, in larger diameter
Tubing stay tube when, guiding piece group can all the time with guiding disk contact, meet versatility of the present utility model.
Compared with prior art, the utility model simple structure, it is reasonable in design, it is easy to operate, can not only be fast and effectively
Tubing is strutted, the requirement of testing inspection is met, and versatility can be realized, reduce the error of internal pressure-resistant test data.
