Problems solved by technology

With the expansion of shipbuilding scale, gravity launching has gradually replaced the way of floating dock launching. Skateboard is an important supporting tool for gravity launch of large ships. There are unsafe factors, and the equipment investment is high, the construction process is complicated, but the utilization rate is very low, the manufacturing cost is high, and the manufacturing time is long

Embodiment Construction

[0015] as follows Figure 1 to Figure 5 A specific embodiment of a 90-meter pontoon airbag row of the present invention as shown to undertake the launching process:

[0016] Brief introduction of the 90-meter pontoon: 90 meters long, 14 meters wide, 2.8 meters deep, design draft 0.4 meters, square flat bottom structure, oblique bow and stern, 9 transverse bulkheads inside, forming 10 empty cabins, decks, The bottom plate and side plate are 10mm thick ship plate, and the total weight of the hull and accessories is 550 tons.

[0017] The technological process of launching the air bag row of the 90-meter pontoon is as follows:

[0018] A) Land translation preparation

[0019] Set 18 1.1-meter-high steel buttresses under the left and right sides of the transverse bulkhead 1, and wedge them tightly with inclined wood. Remove the tire frame symmetrically from the central transverse bulkhead (in the middle of the ship) to the bow and stern directions respectively, and remove the we...

Abstract

The invention relates to a process for shipping and launching a wharfboat which is carried by an airbag row. The launching process is a method adopting a water tractor tug for traction, a land post-tensioning device for protection, a land small-diameter airbag for floating support and displacement, and a water large-diameter airbag row for carrying. By adopting the process for launching the wharfboat, ships can be manufactured at a place close to a wharf or far away from the wharf, the construction time limit, the quality and the security can be ensured easily, and a light-tonnage hoisting apparatus can be used, and thus the ships can be moved to the wharf by a small-diameter airbag row and then carried into water by the large-diameter airbag row. The amount of corresponding airbags (landand water) according to the tonnages of the ships, the airbags can be reused, the investment is small, and compared with the prior shipbuilding and dock building cost that is hundreds of thousands yuan even several hundreds of thousands yuan, the cost by making use of the airbag for launching is only tens of thousands yuan, and thus the launching process does not use large hoisting apparatuses, is safe and reliable, is simple, convenient and practicable, and has low cost.

Description

technical field [0001] The invention relates to a launching process of a pontoon, in particular to a new process of launching a pontoon on a wharf with an upright bank wall by adopting airbags to assist buoyancy. Background technique [0002] Traditional shipbuilding generally adopts floating dock launching, which is only suitable for building small-tonnage ships, and the cost is high and uneconomical. With the expansion of shipbuilding scale, gravity launching has gradually replaced the way of floating dock launching. Skateboard is an important supporting tool for gravity launch of large ships. There are unsafe factors, and the equipment investment is high, the construction process is complicated, but the utilization rate is very low, the manufacturing cost is very high, and the manufacturing time is long. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a barge airbag row launching proc...
