Abstract

The utility model relates to a shipbuilding tooling utilizing a floating dock, which is characterized in that the tooling comprises the floating dock (1), various complete cross sections (2) of a new ship and a three-dimensional regulator (3), ballast water (6) is filled in a ballast tank of the floating dock (1), the complete cross sections (2) of the new ship are arranged on dock blocks (4) of the floating dock (1), and the three-dimensional regulator (3) is assembled on a pontoon deck (5) of the floating dock (1) and is padded at the bottoms of the complete cross sections (2) of the new ship. The shipbuilding tooling can resolve the problems of determining the ship reference line in the floating dock during shipbuilding and quickly adjusting and positioning complete cross sections of the new ship.

Description

Utilize the frock of floating drydock shipbuilding

(1) technical field

The utility model relates to a kind of frock of utilizing shiprepair to carry out shipbuilding with the floating drydock.Belong to the ship building technical field.

(2) background technology

Building berth, dry dock are ship closure and following drainage facility, are widely used in new shipbuilding; Floating drydock and dry dock are widely used in ship repair.These are critical facilitys of shipyard, and investment is big, and the cycle is long.

Along with the new ship demand in the world sharply enlarges, and new construction facilities can't increase in a short time fast, is to alleviate imbalance between supply and demand, and each shipyard will be used for being used for shipbuilding after the dry dock transformation of shiprepair one after another, but the floating drydock is adopted in shiprepair mostly.If the floating drydock also can be used for shipbuilding, then can realize shiprepair and shipbuilding resource sharing to a greater extent, be issued to the purpose that enlarges the shipbuilding production capacity in a short time to greatest extent in the situation that does not need very big fund input, thereby satisfy the demand of the world new ship.And when new ship demand reduced, the floating drydock still can be used for shiprepair, reduced idle facility.But the floating drydock is used for shipbuilding and has a following difficult problem:

Need definite datum line conduct when 1, closing up and close up benchmark, and the floating drydock can't provide the datum line as the land owing to new ship.Because:

1) floating drydock swims on the water surface, and its position and state change along with the variation of stormy waves, morning and evening tides and current.

2) when new ship segmentation (or complete cross section) when putting into the floating drydock, thereby the strained condition at floating drydock can change and produces distortion.

2, new ship segmentation (or complete cross section) is in floating drydock domestic demand quick adjusting location, to satisfy the requirement of shipbuilding period.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can solve above-mentioned in the floating drydock the determining and the frock of utilizing the floating drydock shipbuilding of the quick adjusting orientation problem of new ship complete cross section of boats and ships datum line during shipbuilding.

The purpose of this utility model is to be achieved through the following technical solutions: a kind of frock of utilizing the floating drydock shipbuilding, comprise: each complete cross section and the three-dimensional adjustment machine of floating drydock, new ship, in the ballast tank at floating drydock, add ballast water, on the docking block at floating drydock, place each complete cross section of new ship, the three-dimensional adjustment machine of device on the pontoon deck at floating drydock, three-dimensional adjustment machine pad places the bottom of each complete cross section of described new ship.

The utility model has the advantages that:

1, this frock does not need the extensive new facility that increases, and only existing facility need be transformed.Can save input, instant effect greatly.

2, when not needing to adopt this method to build boats and ships, involved facilities and equipment can be used for shiprepair and building berth (or dry dock) shipbuilding, can not cause the idle of equipment, facility and place.Cut the waste.

3, realize shiprepair facility and construction facilities resource sharing, improved the alerting ability of factory operation greatly.

(5) specific embodiment

Referring to Fig. 4, the layout scheme drawing (drawing in side sectional elevation) of boats and ships in the floating drydock that Fig. 4 relates to for the utility model.As seen from Figure 4, the utility model utilizes the frock of floating drydock shipbuilding, comprise: each complete cross section 2 and the three-dimensional adjustment machine 3 of floating drydock 1, new ship, in the ballast tank at floating drydock 1, add ballast water 6, on the docking block 4 at floating drydock 1, place each complete cross section 2 of new ship, the three-dimensional adjustment machine 3 of device on the pontoon deck 5 at floating drydock 1, three-dimensional adjustment machine 3 pads place the bottom of each complete cross section 2 of described new ship.Utilize the method for floating drydock shipbuilding as follows:

Step 1, in the ballast tank at floating drydock, add a certain amount of ballast water in advance.

Step 2, keeping under the ballast water yield unmodified situation, surveying the amount of deflection control line of standardized straight line on the wing wall in about the floating drydock as the floating drydock.On the pontoon deck at floating drydock, survey and mark the control line of new center line of boat as new center line of boat.

Step 3, new ship segmentation is closed up into a plurality of complete cross sections on total group place, as Fig. 1.And on each complete cross section, survey and draw line of centers, the height and position line of each complete cross section well.Then with hydraulic trolley with each? complete cross section moves to along the river, as Fig. 2.With crane barge first complete cross section is lifted up into the floating drydock again.

Step 4, will pump with the ballast water in the cooresponding ballast tank of first complete cross section, the weight of the ballast water that pumps equates substantially with the weight of first complete cross section.Utilize the described floating drydock of total station survey about in amount of deflection control line on the wing wall, and according to the ballast water in the measurement situation fine setting ballast tank, about making in the out-of-flat of amount of deflection control line on the wing wall less than 10mm.

Step 5, reach height and position all around with what three-dimensional adjustment machine was adjusted first complete cross section, as Fig. 4.

Step 6, second complete cross section is lifted up into the floating drydock,, repeated for the 4th step then as Fig. 5.

Step 7, adjust the position of second complete cross section with three-dimensional adjustment machine, line of centers that surveying on first complete cross section drawn and height and position line are as the benchmark that closes up of second complete cross section.

Step 8, repeat above operation and close up the 3rd complete cross section, with the line of centers of first and second complete cross sections after the balance and height and position line the benchmark that closes up as the 3rd complete cross section.By that analogy, close up up to all complete cross sections and to finish, as Fig. 3.
