Description
Technical field
The present invention relates to hoisting, relate in particular to ultra-large type cylindrical shell sectional hoisting in a kind of deep water pipe laying crane ship manufacture process.
Background technology
The construction of boats and ships normally segmentation is carried out.In deep water pipe laying crane ship manufacture process, hoist base segmentation wherein, that is: cylindrical shell segmentation, because needs are connected with hoist base ring, therefore, very high to its construction precision requirement, be the most critical part that deep water pipe laying crane ship is built.And in manufacture process, especially, in hoisting process, need the strict subsection deformation of controlling, to guarantee the out of roundness of segmentation.
At present, the construction of standing up of cylindrical shell segmentation is one of mode of construction conventionally adopting, and when cylindrical shell segmental hoisting, normally adopts two gauntrys crane to lift.This kind of lifting mode is because two gauntrys crane of needs lift operation simultaneously, and two acting in agreement property of gantry crane cooperation require very high; And cylindrical shell sectional turn-over is more dangerous, can only adopt positive tire to build, but lack strong support while building due to positive tire, not only construction precision can not be guaranteed, and has virtually reduced the safety factor of building.
Another kind of cylindrical shell sectional construction mode is: cylindrical shell segmentation is divided into the anti-tire of two parts and builds, when to cylindrical shell, segmentation lifts, first adopt gauntry crane respectively two parts of cylindrical shell segmentation to be carried out to single standing up, then, carry out again total group, platform, after total group, carry, gauntry crane is used 3 times altogether in front and back again; And during the segmentation of lifting cylindrical shell, need to be equipped with special-purpose hanging device, and special hoisting equipment, not only volume is large, Heavy Weight, and transportation by lighter is inconvenient, and manufacturing cost is very expensive, and economy is poor.This kind of mode due to needs to cylindrical shell segmentation repeatedly stand up, and, need a large amount of frocks and reinforcement material.And after cylindrical shell sectional turn-over, due to cylindrical shell segmentation top heavy now, when platform is always organized, also need, with directly supportting, outside plate is carried out to supporting and location, to prevent that it from toppling over, therefore, more time-consuming effort again; In addition, because cylindrical shell is segmented into the segmentation of 4000T hoist base, gross tonnage is 820 tons of left and right, and during lifting, steel wire angle is larger, is unfavorable for the safety of lifting; And cylindrical shell segmentation top need to be connected with base ring, out of roundness is required very high, be divided into two parts and build repeatedly to stand up and easily cause subsection deformation to be unfavorable for controlling segmentation precision suitable for reading.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of ultra-large type cylindrical shell sectional hoisting, to cylindrical shell, segmentation adopts the mode of anti-tire monolithic construction for it, not only can reduce the access times of gauntry crane, simplified operational sequence, and, improved the Occupation coefficient of loop wheel machine and the one-time-reach-place rate of segmental hoisting operation; Meanwhile, reduced the operate miss of lifting operation, for lifting operation provides safety assurance.
The object of the invention is to be realized by following technical scheme:
A ultra-large type cylindrical shell sectional hoisting, is characterized in that: adopt following steps:
The first step: by a gauntry crane respectively with the upper sport car that is positioned at two ends together with lower sport car sliding block joint, upper sport car links together by two suspension hooks and two rows of hanging, lower sport car links together by a suspension hook and the row of hanging;
Second step: by steel rope by lower sport car be located at the several suspension centres above leg under cylindrical shell segmentation and link together, by steel rope by upper sport car be located at cylindrical shell segmentation opposite on several suspension centres of wall-enclosing board connect together, then, the lifting of control gauntry crane, after all steel ropes keep vertically, control gauntry crane and promote at a slow speed the main hook of sport car and the auxiliary hook of lower sport car, cylindrical shell segmentation is hung to ground;
The 3rd step: the auxiliary hook of the lower sport car that stops, the main hook of sport car in lifting, and rotating cylinder segmentation, until cylindrical shell segmentation is vertical aloft;
The 4th step: after the auxiliary hook of the lower sport car that comes loose, cylindrical shell segmentation is dropped to ground proximity, and remove the auxiliary hook of lower sport car;
The 5th step: the main hook of above sport car is axle system, by cylindrical shell segment level Rotate 180 °, then, then hangs the steel rope of lower sport car auxiliary hook code and links together with standing up;
The 6th step: cylindrical shell segmentation is promoted, and hang ground;
The 7th step: stop the auxiliary hook of lower sport car, reduce gradually the main hook of upper sport car, cylindrical shell segmentation is balanced;
The 8th step: the main hook of sport car and the auxiliary hook of lower sport car in reduction, cylindrical shell segmentation is lain on total group platform, standing up and carrying just of cylindrical shell segmentation all completes.
In described the 8th step, when cylindrical shell sectional turn-over, must constantly note the squareness of steel rope, it is remained in normal range.
In described second step, the distance that cylindrical shell segmentation hangs ground is more than 1 meter.
In described the 6th step, the distance that cylindrical shell segmentation hangs ground is more than 1 meter.
Beneficial effect of the present invention:
1. segmentation adopts the mode of anti-tire monolithic construction to cylindrical shell to cylindrical shell, simplify the operational sequence of lifting operation, reduce the access times 2 times of gauntry crane;
2. guarantee the precision of cylindrical shell segmentation, meanwhile, improved the Occupation coefficient of crane;
3. adopt the row of hanging to carry out lifting operation, the row of hanging not only volume is little, lightweight, balanced capacity good; And in handling process, can not cause segmental structure impaired because of unbalance stress, improve the safety of lifting operation;
4. make hull in carrying out lifting operation process, the utilization of instrument and the arrangement of manpower have obtained good optimization, have improved the one-time-reach-place rate of segmental hoisting operation; Meanwhile, reduced the operate miss of lifting operation, for lifting operation provides safety assurance.
