Background technology
Along with the development of marine oil industry, various purposes dissimilar, different, the ocean platform being suitable for different work environment are built and are applied, self-elevating drilling platform, because of advantages such as its location are strong, job stabilization height, cost are low, becomes the main force of national fishing shelf petroleum exploration and development. And there is the characteristic feature that lift capability is self-elevating drilling platform, wherein, lifting device is the equipment realizing self-elevating drilling platform rising and decline, at present, mode installed by lifting device of the prior art: wheel casing vertically and hull structure close up, draw in lifting device level. Lifting device is placed on dock and closes up stage installation by this mode, and efficiency is lower, and the more dock that occupies hangs the time of machine and the production cycle of dock.
Summary of the invention
For solving the problems of the technologies described above, the present invention provides a kind of installation mode for self-elevating drilling platform lifting device, installs efficiency height, and can shorten dock production cycle.
The present invention is by the following technical solutions:
For an installation mode for self-elevating drilling platform lifting device, comprise the following steps:
(1) installing the step cover of front end roller bearing, make to fit completely between step cover and bearing and axle during installation, what make whisky jack on step cover is supported on lower section;
(2) braking devices of lifting device is removed;
(3) level lifting lifting device; stand up 90 degree and vertically it is placed on casual labour and loads onto; pinion(gear), front end roller bearing, paint are carried out protection; in order to avoid colliding frock to destroy paint; again link up with; utilize chain block adjustment level, make lifting device can vertically enter the bearing support of wheel casing smoothly
(4) when the front end roller bearing of lifting device touches bearing support, suitably loosen lifting rope, make lifting device advance wheel casing by self gravitation;
(5) when lifting device can not only move down with gravity, hydraulic pressure is thereunder installed and drags device;First hexagon nut, screw rod are connected with lifting device; Cover and bolt are installed before secondly installing; Screw block, transmission mechanism, square nut are then installed; Finally connect wobble pump, manifold, dial plate, flexible pipe;
(6) to screw block pressurization, until lifting device puts in place;
(7) step cover that hydraulic pressure drags device, front end roller bearing is removed;
(8) coaming plate outside pad, stopper bolt, bearing support cover plate, bearing support is installed;
(9) grease is injected from bearing support cover plate center grease filler, lubricating bearings.
The technique effect of the present invention: this installation mode can utilize the weight of lifting device itself, accelerates to advance wheel casing, it is to increase install efficiency; Again because lifting device installation phase has been advanceed on total group platform by it, so the duration of service of dock transfer gantry can be saved, and shorten the dock cycle.

Embodiment
If Fig. 1 is that lifting device of the prior art is installed mode and is: wheel casing 2 vertically and hull structure close up, draw in lifting device 1 level.
Such as Fig. 2 to Fig. 4, a kind of installation mode for self-elevating drilling platform lifting device: namely wheel casing is horizontal, lifting device vertically enters. Prepare as follows before installing: (1) familiar with understanding also grasps all design papers, the data such as technical publications of lifting system installation. (2) get support equipment to warehouse and must check its integrity, and check product nameplate, specification, model. (3) whether the outward appearance of monitoring device damages, scratch, paint flake, corrosion and foreign material pollution etc. (4) the complete support equipment of inspection must be had keep a public place clean accordingly, protection against the tide, the security measures such as anti-scratch. (5) wheel casing horizontal positioned, front panel direction is down. (6) remove all surface corrosions and dirt in wheel casing open holes, have the surface contacted to add painting butter at wheel casing with lifting device.
Concrete installation mode comprises the following steps:
(1) lifting device 1 of corresponding numbering is selected according to plan, first the step cover of front end roller bearing 5 is installed before lifting, ensure during installation to fit completely between step cover and bearing and axle, otherwise pad need to be placed, the thickness of pad is by the on-the-spot actual measurement in the opening place of step cover, in addition, what also need to ensure whisky jack on step cover is supported on lower section.
