The utility model has following working process in use:
1. locking process:
In this operation engineering, the load of platform is born by jacking system (all lifting units).
Locking operation is operated by three groups of staff simultaneously, and every group of operating personal (being generally two people) is responsible for the latching device on a spud leg of operation (three strings).In any moment, in same pile leg, only allow the latching device of a string to operate.
Every sleeve locking apparatus operation order is right side or reverse order behind first left side.
Before latching device operation, must be applied on the contact surfaces such as tooth bar voussoir, spud leg tooth bar, slide block, guide rail with enough greases.
As follows to operate single string latching device process:
(1) retraction jack: adjust vertical oil cylinder and make pulley end touch tooth bar voussoir overhead gage, drive upper and lower jack to make it in complete retracted mode.
(2) to tooth: adjust the position of tooth bar voussoir vertical direction by vertical oil cylinder, adjust tooth bar Xie piece horizontal direction position by cross cylinder, use visual method control tooth bar Xie piece to engage with spud leg tooth bar; In this process, need repeatedly to operate vertical oil cylinder and cross cylinder, until engaged.
After left side tooth bar voussoir and spud leg tooth bar align, with same process operation right side string fluid cylinder, repeat this step.
After tooth is completed, vertical fluid cylinder need be retracted.
(3) eliminate gap: adjust successively the upper and lower jack of left string side, make skewback and tooth bar voussoir, tooth bar voussoir and spud leg tooth bar good contact.Retract vertical fluid cylinder after eliminating completely in back lash, vertical fluid cylinder and tooth bar voussoir are thrown off completely.Operate the jack up and down of right string side, realize the good contact of skewback, tooth bar voussoir, spud leg tooth bar.
(4) locking: operate left string upper lateral part motor and drive jack to make top skewback, tooth bar voussoir, spud leg tooth bar good contact, until motor lock-rotor " loses to lift and stops ".Check lower motor driven jack, guarantee bottom skewback, tooth bar skewback, spud leg tooth bar good contact, operation lower motor driven jack is until stall " losing act stops ".As shown in Fig. 5-1.
The right string side jack of same operation.
When preparing the operating modes such as towage, while being mainly latching device lower end bearing load, operation order is contrary with (4) operation order.
(5) after all latching device locking of platform work, jacking system (lifting unit) is moved downward to the transfer of implementation platform load from jacking system (all lifting units) to fastening system.
2. disconnecting process (when platform rises state)
Detailed process is as follows:
(1) drive respectively the bottom jack of all strings of this spud leg, make skewback and tooth bar skewback throw off certain interval (vertical 10mm left and right).
(2) platform load is transferred to jacking system (all lifting units) from latching device.
(3) adjusting vertical oil cylinder makes pulley end touch tooth bar voussoir overhead gage.
(3) drive string top, left and right jack, string top skewback and tooth bar skewback are thrown off completely.
(4) drive string bottom, left and right jack, string bottom skewback and tooth bar skewback are thrown off completely.
(5) control left side cross cylinder, coordinate vertical oil cylinder, make tooth bar skewback retract (being that tooth bar skewback and spud leg tooth bar are at utmost thrown off) completely, if shown in 5-2.Then carry out east side operation.
(6) in the time that top jack, bottom jack, cross cylinder are not retracted under this operation, operate the high pressure knob on mobile control terminal, the high pressure conditions of activation solution pressing system, then repeat the instruction of retracting.
Note: after top jack, bottom jack, cross cylinder start to move freely, the high pressure conditions of necessary shutdown system, changes normal condition into, otherwise will damage system.
Disconnecting process (when spud leg rises state)
Detailed process is as follows:
(1) drive respectively the top jack of all strings of this spud leg, it is retracted completely.
(2) platform load is transferred to jacking system (all lifting units) from latching device.
(3) drive string bottom, left and right jack, string bottom skewback and tooth bar skewback are thrown off completely.
(4) adjusting vertical oil cylinder makes pulley end touch tooth bar voussoir overhead gage.
(5) control left side cross cylinder, coordinate vertical oil cylinder, make tooth bar skewback retract (being that tooth bar skewback and spud leg tooth bar are at utmost thrown off) completely, if shown in 5-3.Then carry out east side operation.
(6) in the time that top jack, bottom jack, cross cylinder are not retracted under this operation, operate the high pressure knob on mobile control terminal, the high pressure conditions of activation solution pressing system, then repeat the instruction of retracting.
Note: after top jack, bottom jack, cross cylinder start to move freely, the high pressure conditions of necessary shutdown system, changes normal condition into, otherwise will damage system.
3. the installation process of latching device
The sequence of erection of latching device and jacking system
The latching device pedestal of jack-up platform and jacking system pedestal are on same box base, because jacking system and pedestal are generally positioned on main deck, so under normal circumstances, the pedestal of latching device is together built with hull, and latching device and jacking system are installed and carried out according to following order:
Hull construction (latching device pedestal and hull are together built)
Latching device mechanism part is installed, and makes it in disengaged condition (now spud leg is not also installed)
Spud leg is installed
Jacking system is installed, jacking system base bottom and latching device pedestal are welded
Box beam and round steel (K type or X-type structural strengthening structure) are installed
Latching device General Requirements is installed: because the parts such as HM Hydraulic Motor are to install in the later stage, adjust jack leading screw and need to prepare special tool; As need be adopted additive method to adjust the flexible of jack screw mandrel without special tool.Lifting screw need be equipped with lifting earrings, if because scantling of structure restriction can not provide, and the special lifting device while needing to consider to install.After latching device finishes safely, operation tooth bar skewback by it in complete disengaged condition.Latching device should sequentially be installed the single string of single spud leg, avoids installing many string latching devices simultaneously.
Concrete installation steps
After latching device pedestal has been built, mounting guide rail.
Before jack is installed, cleaning leading screw, housing attachment face, and leading screw is reached to range, be coated with grease (being as the criterion with the explanation of jack working service)
The protruding sphere of jack leading screw is coated with grease, clears up the recessed contact surface of very heavy leading screw attaching parts, and jacking header is arranged on to leading screw head.Mounting screw counterbore place need fill RTV silica gel to prevent corrosion.
After cleaning jack pedestal attachment face, lifting jack, and be fixed on moon pool pedestal by bolt (screw).
After jack installs, slip skewback is installed.
Horizontal push cylinder is arranged on pedestal.
Tooth bar skewback is installed, it is connected with horizontal push cylinder.Because latching device hydraulic power line now does not connect, availablely tie up at pedestal provisional tooth bar skewback as rope etc., adjust upper and lower jack leading screw and stretch out, make horizontal push cylinder in level
By welding manner, vertical oil cylinder mounting bracket is fixed on pedestal, vertical oil cylinder assembly parts (pulley assembly has been arranged on piston rod head) are installed.
Although the utility model discloses as above with preferred embodiment; but not of the present utility model in order to limit; those skilled in the art can also do other variations in the utility model spirit; and be applied in the NM field of the utility model; certainly, these variations of doing according to the utility model spirit all should be included in the utility model scope required for protection.
