Abstract
The invention discloses a method for sectional turning the ship and special rolling bracket, comprising: (1) each side edge of one end of section has one arc rolling bracket while its axis is parallel to the sectional turning surface; (2) the invention uses the crane to hang the another end of section to turn the section for 180 degrees along the arc surface of rolling bracket to complete the sectional turning. The inventive special rolling bracket has a round arc surface and a connection plate arranged on the chord of round arc and connected to the section via connection hole. Compared to present technique, the invention can fully utilize the lifting ability of crane while the section weight can be two times of the section weight turned by two crane; since the section is large, the number of sections is fewer, the closing quality of ship is confirmed, and the period of building ship can be shorted; since the section is turned by the support of rolling bracket, it has better support condition, reliable safety, simple operation, and fast turning speed.
Description
[technical field]
The present invention relates to the ship building field, particularly a kind of in the hull construction process method and the special-purpose rolling rack of ship hull sectional turn-over.
[background technology]
In the hull construction process, take the anti-body construction method of segmentation because of hull and build, after making, the segmentation of part hull needs to stand up, and could lift the enterprising body of navigating of building berth and close up greatly.In the prior art, general middle-size and small-size shipyard all adopts crane associating body turning method now, carries out the sectional turn-over operation.That is: size and the weight according to segmentation adopts two crane (or wheel cranes of a crane, or a crane two automobiles hangs) the segmentation at both ends is sling, then with the loose cable of the crane of an end, and segmentation is only played by the crane of the other end, and then with 180 ° of segmentation rotations, again sling by former crane, till the state of being up to the standard, stand up end.Have the large-scale shipyard that large-scale bridge type hangs, generally use bridge-type to lift up into capable sectional turn-over.Promptly utilize bridge-type hang on dolly and following dolly hang the two ends of segmentation respectively, be similar to the action of standing up of aforementioned two cranes.More existing problems when above-mentioned these methods are carried out sectional turn-over, as: the size that has limited segmentation, because when segmentation is divided, must consider at first that fragment size can not be above standing up the desired crane capacity of technology, should make the weight of segmentation satisfy the load carrying ability that crane can carry, existing crane capacity can not be made full use of, and because segmentation is divided less, cause the work capacity of building berth segment folding big, the poor quality guarantees, make the building berth production cycle long, this is the bottleneck problem of shipbuilding, is domestic and international shipbuilding yard urgent problem.In addition, this method poor stability in the lifting process, causes the fold of segmentation or segmentation local structure easily.And during sectional turn-over required time long owing to need one lifting of two cranes,, influenced other work that need lift by crane so take two cranes in the whole process, economy is bad.
[summary of the invention]
The objective of the invention is in order to overcome the deficiencies in the prior art, and provide a kind of ship hull sectional turn-over new mode and the special-purpose frame that rolls, this method only to need a crane, and be equipped with the special-purpose auxiliary frame that rolls, can finish the operation of standing up of segmentation, not only safe but also can make full use of existing crane capacity.
The present invention discloses a kind of ship hull sectional turn-over method for addressing the above problem, and it is characterized in that comprising the steps:
(1) at two sides of segmentation one end, fix the frame that rolls of a cambered surface respectively, the axis that cambered surface is rolled frame is parallel with segmentation upset face;
(2) with the crane other end of segmentation of slinging, make segmentation along the cambered surface of rolling frame, do 180 ° of motions of upset, finish sectional turn-over.
The present invention is characterized in that for realizing that above-mentioned ship hull sectional turn-over method has designed a kind of special-purpose rolling rack the said frame that rolls has a circular arc driving surface, and a locational connecting bore and the segmentation bonded assembly connecting panel used that is arranged on the string of circular arc.
Method of the present invention advantage compared with the prior art is:
Therefore 1. can give full play to the crane capacity of crane, segmentation can be done greatly, usefulness is stood up and is rolled the twice that segmentation weight that frame stands up can be the segmentation weight of standing up with two cranes;
2. because of segmentation is big, the number of fragments of hull has been lacked, and guarantees that easily hull closes up quality, has shortened the cycle that building berth is built;
3. because segmentation is to overturn under the entrusting of rolling frame, strained condition is good, and is safe and reliable;
4. simple to operate, the speed of standing up is accelerated greatly.

[specific embodiment]
Ship hull sectional turn-over method of the present invention, at first will be at two sides of segmentation (2) one ends, fix (3) of one 180 ° arc surface respectively and roll frame, it is parallel that the axis that cambered surface is rolled frame and segmentation upset face need, and the string at circular arc place is vertical with the longitudinal axis of segmentation; Use crane (1) other end of segmentation of slinging then, as shown in Figure 1, at this moment roll the frame holder and segmentation and roll on the ground; When θ=90 °, crane to protract (hanging for bridge-type is exactly to the reverses direction travelling car), makes θ＞90 ° with suspension rod, and segmentation forms heeling condition, as shown in Figure 2.At this moment along with the loose cable of crane, segmentation is rolled to opposite side along with rolling frame under the effect of gravity, is in horizontality up to segmentation, and sectional turn-over finishes.
The present invention is used for the special-purpose rolling rack of ship hull sectional turn-over method, shown in Fig. 3,4, it rolls the frame circular arc is the circular arc platform, and the locational connecting panel (7) of circular arc string is bar shaped, the length of connecting panel is less than arc diameter, and the center of connecting panel also has a groove (4) vertical with arc axis.Connecting bore on the connecting panel (5) is positioned at the two ends of connecting panel.For making things convenient for handling can also be provided with one or two suspension ring hole (6) on the frame rolling.Shown in Fig. 5-7, segmentation wallboard (8) (or auxiliary connecting panel) is inserted in the groove roll on the frame during installation, pass connecting bore on connecting panel and the segmented side walls and fixing getting final product with screw.
For some shipbuilding yards, only need do the frame that rolls of several different radiis according to this factory's shipbuilding capacity, form and roll frame series and can use, not only economy but also make things convenient for for shipbuilding.The thickness that rolls frame is according to rolling the size of frame and difference is generally 300mm-400mm.
