Embodiment Construction

[0033] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.

[0034] according to Figure 1-Figure 5 As shown, the process of launching a large ship using an air bag includes the following steps:

[0035] Preparatory steps:

[0036] 1) Calculation of the ship's bow and stern draft, calculation of the initial speed of the hull touching the water, and the launch equipment is fully prepared;

[0037] 2) Install the ship stabilizing device, and calculate the traction force when the ship stabilizing device withdraws the pier;

[0038] 3) Check the airbag slideway. The slope of the airbag passing through the gate of the dock should be treated gently. The water depth of the stern fall area should be calculated. If the depth is not enough, the silt should be dredged;

[0039] 4) Arr...

Abstract

The invention discloses a technology for launching a large shipping vessel through an air bag. The technology comprises the following steps: calculating the drafts of a ship fore and a ship aft; installing a ship stabilizing device; checking an air bag slideway; distributing the air bag; installing a control cable; inflating and removing piers; clearing away all barriers in the slideway; waiting for tide level; unhooking and launching; berthing the ship. The technology has the main advantages of solving the launching difficulties of air bag launching in narrow river channel (inner harbor) due to insufficient buffer distance and draft. When the air bag launches, only two heavy objects and four high-strength cables need to be provided, so that the construction cost can be lowered; on the premise of ensuring the launching safety of the ship, the minimum energy consumption can be realized. According to the invention, a new launching method is provided for national air bag launching construction, and has obvious economic benefits, creative technological values and excellent popularization and application prospects.

Description

technical field [0001] The invention relates to a ship launching process, specifically a process for launching a large ship using an air bag, and is especially suitable for launching a ship limited by water space and water depth (no swells or undercurrents) or for ships with a launching tonnage of less than 10,000 tons. Ship launching operations with controlled trajectory. Background technique [0002] In the process of large-scale ship construction, the launch of ship airbags is an important node in shipbuilding engineering. At present, the docks of most shipyards at home and abroad are close to sea areas and large rivers. The buffer distance of launching is greater than 500 meters, and the water depth is greater than 10 meters. Ships launching in wide sea areas (rivers) do not need to control the trajectory after launching, and the launching depth is fully satisfied. The stern fall requirement, the difficulty of launching is low. However, for shipyards along narrow river...
