Abstract
The invention relates to an underwater installation process of a removable deck of a million-ton roll-on-roll-off ship. The underwater installation process is particularly suitable for the removable deck of the million-ton ship, and therefore the removable deck can be guaranteed to be installed inside the million-ton ship successfully, and construction time of a ship occupying a shipway. According to the underwater installation process of the removable deck of the million-ton roll-on-roll-off ship, after the ship launches, the removable deck of double layers and a removable slope way of double layers are transported into a cabin through a floating crane and a flat car, and are hung between a main deck and an upper deck, integrally installation is carried out through a hand-drive block, and fixation is carried out through hoisting pads and steel wire ropes, the removable deck is dragged through the steel wire rope hung on the upper deck, the removable deck is guaranteed to move vertically by utilizing a guide rail inside a boardside cabin, can be packed up when not used, and can be released when used, and the working stability of the removable deck is guaranteed through a foldable drawing rod.
Description
Technical field
The present invention relates to a kind of mechano decking mounting process being exclusively used in roll-on-roll-off ship, particularly relate to a kind of for ten thousand tons of roll-on-roll-off ship mechano deckings mounting process under water.
Background technology
Roll-on-roll-off ship is the delivery truck of various automobile, fill up container or goods and trailer etc., and its cargo space is higher.This ton roll-on-roll-off ship shipowner, in order to maximizing the benefits, requires middle hold floor height to increase again, and between main deck and upper deck, arranges two-layer mechano decking.When goods is high capacity waggon, mechano decking is closed at below upper deck, do not hinder lorry to pass in and out; When goods be small-sized rolling cargo or roadlice time, mechano decking can be put down, increase cargo carrying area.
Former requirement of this mechano decking is installed in our factory, and after waiting launching, shipowner requires that our factory installs, and therefore, mechano decking only has to be installed under water.During owing to installing under water, boats and ships to be unlike on building berth steadily, can wave, and hull structure complete all along with current, so, mechano decking to enter cabin, installation difficulty all larger.
Summary of the invention
The object of the invention is to work out one and be used in particular for ten thousand tons of roll-on-roll-off ship mechano deckings mounting process under water, thus ensure that mechano decking can be installed in ten thousand tons of roll-on-roll-off ships under water smoothly, reduce the construction time that boats and ships take building berth.
In order to realize foregoing invention object, the invention discloses a kind of ten thousand tons of roll-on-roll-off ship mechano deckings mounting process under water, referring to and the mechano decking of bilayer and mov-ing ramp are installed on the method between main deck and upper deck at launching rear-mounted, comprise the following steps:
(1) mechano decking corollary equipment is installed, respectively by guide rail, and upper and lower support reinforcing, steel rope suspension centre is strengthened being installed on hull, and described guide rails assembling is in ship side cabin, and described steel rope suspension centre is strengthened being fixed on upper deck;
(2) from stem mechano decking, mechano decking is sent into middle hold from tail-gate, be higher than in step (1) lower support be fixed in hull bottom when described mechano decking enters cabin and strengthen;
(3) larboard mechano decking is installed,

As improvement of the present invention, also have additional support between described tail-gate and duck tail, described mechano decking, by crane barge, hangs after on flat truck and sends into middle hold from tail-gate.The tail-gate hauled due to steel rope cannot bear the weight of flat truck and mechano decking, therefore between tail-gate and duck tail, after extension supporting, makes the flat truck loading mechano decking can enter cabin smoothly.
Improve as of the present invention another, the squareness≤3mm of step (1) middle guide, the distance tolerance between two guide rails of every block mechano decking is no more than ± 5mm.Moreover, the gap further disclosed between described mechano decking is 30mm.
Thus not only ensure that the particularity that mechano decking is installed and stability, and can avoid colliding when starting.
As further improvement of the present invention, also comprise in advance according to mechano decking installation site in described step (1), in hull, line indicates its precise mounting position.Because the installation of mechano decking is carried out after launching, so boats and ships easy run-off the straight on the water surface, thus affect the accurate installation of mechano decking, utilize the method for ruling in advance and indicating, the installation site of mechano decking can be found fast accurately, improve the speed that mechano decking is installed under water further.
As further improving, described in described step (1), guide rail is welded in ship side cabin.Due in installation process, the position of guide rail needs fine setting further, so adopt the mode of spot welding, can retain its adjustable, facilitate follow-up installation on the basis ensureing guide rail stability.
As further improving, plank in bulk is sealed up after removing by the bont in described step (4-4) and (7-4).Because plank in bulk easily causes potential safety hazard after bont is removed, so sealed up, so as to avoid an accident.
Finally, the present invention further discloses in described step (9), adopts manual basic electrode E5015 or CO
2gas shield welding, to all guide plates, support, eye plate, back-up block welding, is opened deep penetration welding groove to the eye plate of hanging steel rope rigging with the employing of support eye plate and is welded, ensure the weld defects such as every layer of face of weld flawless, pore, undercut, overlap.
In sum, after adopting technical scheme disclosed by the invention, by hanging on the rope traction mechano decking of upper deck, utilize the guide rail in outboard tank, ensure that mechano decking moves up and down, the used time can not pack up, used time discharges, and ensures its working stability by support, folding pull bar.
