Abstract
The invention discloses a method for overturning a C-shaped block of a large-size ship. When the weight of the C-shaped block exceeds the safety range of an upper trolley or a lower trolley of a gantry crane of an erection field for conducting independent craning but does not exceed the integral hoisting capacity of the gantry crane, by means of the method, the C-shaped overweight block can be overturned safely, thereby the fitting-out rate of the block is raised, the integrity of the block is improved, hoisting work generated during the erection period is reduced, the erection cycle and the whole construction cycle of the ship are obviously shortened, production efficiency is greatly improved, and quite considerable economic benefits and social benefits are achieved.
Description
Technical field
The present invention relates to the turn-over method of a kind of large ship C type complete cross section, particularly to the hanging method of a kind of large ship cargo hold C type complete cross section, belong to shipbuilding technology field.
Background technology
Along with fitting-out integrity and the size of complete cross section, the weight of boats and ships complete cross section step up, the building technology of boats and ships complete cross section constantly strides forward towards the direction maximized, and has become as the development trend of shipbuilding industry.But, the maximization of complete cross section receives the impact from shipbuilding key element, in the restriction of the loop wheel machine elevating capacity being mainly reflected on dock (or building berth).Considering the safety coefficient of lifting, actual safe elevating capacity will be less.
Summary of the invention
On the basis of tradition processing, adopting General welding and the process equipment of shipyard, by existing parts being made the simple transformation in place, it is achieved that the semiautomatic welding welding of T profile parts, substantially increasing production efficiency.
The invention provides the turn-over method of a kind of large ship C type complete cross section, its weight being applied to work as C type complete cross section has been over closing up the safety range that on the straddle truck in place, dolly or lower dolly individually lift by crane, but during less than the integral hoisting ability of straddle truck.
The present invention is achieved by following steps:
1) apply a kind of tool part landing and standing up, this tool part is positioned when body section makes, is welded in Ship Structure；
2) C type complete cross section always organizes lift-launch with ship hull plate for basal plane, in the middle part of inner bottom plating, main deck, the correct position of main-deck stringer arrange C type complete cross section close up greatly hanger；
3) hanger being arranged in inner bottom plating place hangs lower dolly, is arranged in the hanger in the middle part of main deck and hangs up dolly, and C type complete cross section, to start hoisting and overturning, makes C type complete cross section rotate around landing turning tool part in the process, lands and should arrange necessary chock under turning tool；
4) paying close attention to the stressing conditions of dolly on straddle truck, bear the weight of a part of complete cross section owing to landing turning tool, the stress of upper dolly should control within safety range；
5) after upper dolly stressing conditions is stable, lower dolly breaks off relations, and the hanger being arranged in main-deck stringer place is hung lower dolly, and operation is stood up in the lifting continuing C type complete cross section, until C type complete cross section reaches the state closed up.
The complete cross section quantity of current boats and ships will directly affect overall the closing up the cycle of boats and ships with closing up to hang to count, and after complete cross section maximization, the lift-launch of boats and ships be closed up the shortening in cycle and serve obvious facilitation.Complete cross section divide process in, occur more than the complete cross section of safe elevating capacity unavoidably, how to balance complete cross section weight and quantity, become shipbuilding enterprise have to faced by difficult choice.The turn-over method of a kind of large ship C type complete cross section provided by the invention contributes to enterprise after complete cross section size, weight being increased, and remains able to realize the method that lifting is stood up.It possesses advantages below:
1) adopt and land turning tool part, so as to bear the weight standing up a part of complete cross section in process at C type complete cross section, decrease straddle truck load in complete cross section hoisting and overturning process, make lifting operation remain in the scope of security clearance and carry out；
2) turning tool that lands can be recycled, and is conducive to the raising of shipyard materials'use efficiency；
3) owing to the size of complete cross section and weight are bigger, more outfititem can in the installation of complete cross section stage, and the integrity of complete cross section accommodation outfitting is ensured to greatest extent；
4) the workload reach making to close up greatly, total group of stage and can complete more to close up welding job, closes up greatly the cycle provide strong support for shortening.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described, the total segment length of C type 24.5 meters of the present embodiment, wide 8.1 meters, high about 25.6 meters, complete cross section weight about 695 tons, this complete cross section carries out turnover hoisting in dock, and the elevating capacity of two suspension hooks of dolly respectively 350 tons and 350 tons on straddle truck, the elevating capacity of the single suspension hook of lower dolly is 450 tons.The operation of standing up of this C type complete cross section carries out as follows:
1) in the cargo hold turn of the bilge sectional making process of composition C type complete cross section 1, by a kind of tool part 2 welding equipment of standing up of landing on the outside plate of the segmentation turn of the bilge, together carrying out total group with turn of the bilge segmentation；
2) C type complete cross section carries out total group with outside plate for basal plane in depressed place, total group terminate after, carry out lifting and strengthen the installation of supporting construction 3, remove associated construction equipment, and remove scaffold；
3) by steel wire rope, the hook of upper and lower for straddle truck dolly and complete cross section hanger are coupled together, wherein: the hanger 4 being arranged in inner bottom plating place hangs lower dolly, is arranged in the hanger 5 in the middle part of main deck and hangs up dolly；
4) tightening up along with the upper and lower car rope of straddle truck, C type complete cross section is to start hoisting and overturning；
5) chock 6 should be set under turning tool landing, make C type complete cross section rotate around landing turning tool part 2 in lifting process；
6) paying close attention to the stressing conditions of dolly on straddle truck, the stress of upper dolly should control within safety range；
7) after upper dolly stressing conditions is stable, lower dolly breaks off relations, and the hanger 7 being arranged in main-deck stringer place is hung lower dolly, and lower dolly continues to tighten up steel wire rope, until C type complete cross section reaches the state closed up.
In addition to the implementation, the present invention can also have other embodiments, all employings to be equal to replacement or the technical scheme of equivalent transformation formation, all falls within the protection domain of application claims.
