The drilling equipment system module mainly comprises a lower base sliding system, a slideway beam and a drilling platform surface. The long shaft of the lower sliding base system is designed to be 45 tons, and is generally a frame structure of 17m multiplied by 9m multiplied by 0.7m, and two transverse supporting shafts are arranged and mainly comprise main upright posts and supporting section steel. The lower base system is difficult to construct, mainly embodying the construction precision and the folding precision of two long shafts, wherein the folding precision is the most important. In the prior art, the long shaft vertical piece lifted by the crawler crane cannot be separated from the slideway, more resources in the slideway area are occupied, the construction cost is increased, the body is turned over by using the auxiliary lifting of the truck crane and more manpower for auxiliary pulling, and the long shaft piece can shake in the lifting process of the crawler crane, so that the long shaft can be deformed. In the walking process of the crawler crane, the preliminary preparation work such as road surface leveling, steel plate laying and the like is complex. When the group is to the operation, the group is to the adjustment of falling position, needs the manpower to carry out the guide chain cooperation, and more manpower is carried out the cooperation and is hoisted the activity duration long, and the construction is more complicated, and construction cycle generally is about 25 days, and the safety risk is great. Therefore, there is a need in the art for a method and apparatus that can shorten the assembly time of the slide, save the resources of the field, save the labor, and reduce the cost of the project.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a method for hoisting a long shaft vertical piece of an offshore oil drilling machine.
In order to achieve the purpose, the invention is realized by the following technical scheme:
a method for hoisting a long shaft vertical sheet of an offshore oil drilling rig comprises the following steps:
a. hanging a main hook of the portal crane on an auxiliary lifting lug of a long shaft vertical sheet of the marine petroleum drilling machine, and hanging two auxiliary hooks of the portal crane on a turning-over lifting lug of the long shaft vertical sheet of the marine petroleum drilling machine;
b. synchronously lifting the vertical slice of the long shaft of the offshore oil drilling machine by the main hook and the two auxiliary hooks, turning over the vertical slice of the long shaft of the offshore oil drilling machine by the two auxiliary hooks, and lifting the vertical slice of the long shaft of the offshore oil drilling machine by the main hook for positioning;
c. after the drop position adjustment meets the precision requirement, fixedly connecting the winch with the long shaft to anchor the winch in the direction vertical to the long shaft;
d. the lower end of a long shaft base of the long shaft vertical piece of the offshore oil drilling machine is welded on a temporary clamping plate fixed on a horizontal plane, after temporary fixation is achieved, a lifting rope of the portal crane is removed, and the work of the vertical piece is completed.
The main hook adopts a high-strength sling or a steel wire rope.
The auxiliary hook adopts a high-strength hanging strip.
The vertical pieces of the long shafts of the offshore oil drilling machine are provided with two long shafts, the number of the windlasses is four, every two windlasses form a group, and each group is fixedly connected with the upper end of each long shaft.
Compared with the prior art, the invention has the beneficial effects that: the three hook heads of the portal crane are used for erecting the sheets, the three hooks are synchronously and integrally lifted, the two small hooks are synchronously turned over, the large hook assists in lifting, the single-group adjustment of the falling position is realized, fewer construction operators are required in the lifting process, the folding period is short, and the safety risk is reduced; in addition, the sling is used for replacing a traditional steel wire rope in the falling position adjustment, the falling position adjustment efficiency is high, and the accuracy is high.
Drawings

FIG. 2 is a schematic diagram of a long shaft stand of an offshore oil rig in a landing position.
Detailed Description
The invention is further illustrated by the following examples.
The gantry crane comprises three hook heads, a main hook and two auxiliary hooks, the distance between the two auxiliary hooks is generally 12 meters, the distance between two main upright posts of a long shaft of the drilling machine module is 15-17 meters, so that the two auxiliary hooks are hung on the upright piece turning lifting lugs, and the main hook is hung on the two auxiliary lifting lugs. The main hook adopts high strength suspender or wire rope, adopts high strength suspender in this embodiment. The auxiliary hook adopts a high-strength hanging strip. Because the hanging strip has elasticity, when the auxiliary hook single hook is adjusted up and down, the assembly and the falling process can be adjusted along the axial direction of the long shaft conveniently.
The method for hoisting the long shaft vertical piece of the offshore oil drilling rig as shown in the figures 1-2 comprises the following steps:
a. hanging a main hook of the portal crane on an auxiliary lifting lug of a long shaft vertical sheet of the marine petroleum drilling machine, and hanging two auxiliary hooks of the portal crane on a turning-over lifting lug of the long shaft vertical sheet of the marine petroleum drilling machine;
