The operation principle of the spud leg erection device that the present invention provides is as follows:
Before one action assembles, elastomeric element 4 need to be compressed, make elastomeric element 4 can produce edge
The axis direction of sleeve 1 is towards the compression stress of sleeve 1 head end, and specific implementation is for screwing the first locking screw
Female 3, promote pull bar 2 to stretch out to the tail end of sleeve 1, pull bar 2 band dynamic pressure plate 5 and backing plate 12 compress jointly
Elastomeric element 4, and then make elastomeric element 4 can produce compression stress, and by controlling the extension elongation of pull bar 2
The size of this compression stress can be controlled, it is ensured that the offset loading force that this compression stress produces when deflection more than spud leg b
Can, compress complete, connecting plate 13 and the wedge bracket a of this spud leg erection device are welded together, and ensures
Guide wheel 6d and spud leg b laminating after welding, this spud leg b can be always maintained at vertical state.
When one action is complete, when secondary work starts, spud leg b is probably due to working condition, environmental load
Deflecting in the opposite direction etc. factor impact, guide wheel 6d no longer fits with spud leg b simultaneously, it is therefore desirable to unclamp
First locking nut 3, and adjust regulation screw 10, make guide wheel 6d and spud leg b again fit, continue meanwhile
Continuous turning regulates screw 10 and makes elastomeric element 4 compress, and then produces certain compression stress.
The spud leg erection device that the embodiment of the present invention provides, it is possible to the spud leg of righting oblique spud leg erection device side,
Spud leg erection device can be arranged multiple along the even circumferential of spud leg, and multiple spud leg erection devices can phase interworking
Close, thus keep spud leg to be near vertical state, within making spud leg deflection be in controlled range, the most anti-
Only wedge bracket damages spud leg, and ensures the normal elevating movement of lifting of ocean platform system.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all the present invention's
Within spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
