Working end and the location hole are pin hole cooperation.
When the tensioning hydro-cylinder A to riser pipe clamping system is constrained, steadying plate 320 is needed by promotion oil cylinder 330
It could work after release, and in the work of riser pipe clamping system, steadying plate 320 cannot interfere riser pipe clamping system
Work, so needing to return to original position；But in order to avoid steadying plate 320 skids off, make the riser pipe in steadying plate 320 and work
Clamping system collides, and just steadying plate 320 is return back to behind original position limit steadying plate 320 using positional cylinder 340 here
Sliding guarantees that steadying plate 320 will not be in contact with marine riser clamping system.
It further include accumulator as the supplement to above-mentioned technology, the accumulator is connected to the oil for pushing oil cylinder 330
Lu Zhong, the accumulator are used to buffer riser pipe clamping system and swing the kinetic energy generated.
It is that compression energy or position can store that accumulator, which can be in due course the energy conversion in system, works as system
When needing, and compression energy or position can be changed into the energy such as hydraulic or air pressure and released, mend feed system again.When system wink
Between pressure increase when, the energy of this part can be absorbed in it, to guarantee that whole system pressure is normal.So when constraint marine riser
When clamping system, marine riser clamping system, which swings the kinetic energy generated, can be transmitted to steadying plate 320, due to pushing oil cylinder 330 to install additional
Accumulator, therefore the kinetic energy that steadying plate 320 is subject to is absorbed after promotion oil cylinder 330 by accumulator, to largely share
The kinetic energy of marine riser clamping system output ensure that and set so that the stress concentration point on device be made not will receive excessive load
Standby physical life is longer.
In addition, two restraint devices are one group, two restraint devices 500 are for constraint riser pipe respectively
