Embodiment 1

[0046] Present embodiment adopts floating slipway 1 to launch ship 2, see illustration 1, 2, and this floating slipway parameter is 95 meters long, 28 meters wide, and maximum draft is 6 meters, and ship parameter is total length 71 meters, molded width 19 meters, molded depth 4.2 meters, 800 tons of dead weight.

[0047] The method of launching a ship using a floating berth is:

[0048] (1) Fixed launching ship: two steel wire ropes 6 with a diameter of 38 mm, one end is connected to the two eye plates 5 welded on the bow of the launching ship by a shackle, and the other end is connected to the 100-ton safety tension eye plate welded on the floating berth deck superior.

[0049] ⑵Arrangement of airbags 3 and supporting piers 4: Insert twelve uninflated marine high-strength airbags at the bottom of the launching ship. The diameter of the airbags is 1.5 meters and the length is 15 meters; On the central axis of the launching ship; there can be multiple supporting piers placed...

Embodiment 2

[0054] Present embodiment adopts launching and launching ships on 7 decks of carrying barge, see image 3 , 4 , that is, on a carrying barge with a load of 7,800 tons, a barge is launched. The parameters of the carrying barge are 69 meters in total length, 20 meters in width, 5.5 meters in depth, and 1,200 tons in weight; the parameters of the launching ship are: length 91 meters, width 24 meters and a molded depth of 5.5 meters.

[0055] The method is:

[0056] (1) Fixed launching ship: two steel wire ropes with a diameter of 42 mm, one end is connected to the two eye plates welded on the bow of the launching ship by using a shackle, and the other end is connected to the 120-ton safety tension eye plate welded on the stern plate of the carrying ship .

[0057] ⑵ Arrangement of airbags: Insert fourteen uninflated high-strength marine airbags at the bottom of the launching ship. The airbags have a diameter of 1.5 meters and a length of 18 meters; Axis; there may be multiple...

Abstract

The invention relates to a ship launching method on a floating slipway or a carried barge deck. Ship launching on the floating slipway or the carried barge deck is longitudinal launching, and a mode that the tail firstly enters the water forwards is adopted; and the launching declivity of the floating slipway of a carried barge, the sliding force of a launching sip and the quantity and pressure intensity of airbags need to be calculated in advance before launching. The method comprises the steps of (1) fixing the launching ship; (2) arranging airbags; (3) inflating the airbags to jack the launching ship and removing a support pier; (4) adjusting the weight and a pitch angle of the floating slipway or the carried barge; and (5) cutting off a fixed wire rope at the head of the launching ship by adopting an oxygen-acetylene gas cutting method, and enabling the launching ship and the rolling airbags to enter water together under the action of the sliding force of the launching ship, and finally retracting the airbags, thus completing launching. Ship construction on the water without a dock can be achieved, occupation of the land and the coastline can be effectively reduced, environment protection is facilitated and the ship launching method has good social and economic benefits.

Description

technical field [0001] The invention belongs to the field of ships and relates to the launching of ships, in particular to a method for launching and launching ships on a floating berth or a deck of a carrying barge. Background technique [0002] Ship launching generally adopts the way of slideway launching, airbag launching or floating dock launching, while the existing slideway launching and airbag launching all need to be realized on the berth or ramp built on land. Land slipways or ramps are generally concrete structures, which need to occupy land and have an impact on the environment; moreover, floating docks are expensive to build and maintain. [0003] We know that barge transportation usually requires special barges, also known as mother and daughter ships. The barge is used for river-sea combined transport. The operation process is to load the barge (also known as the sub-ship) with cargo, and then load the barge on the barge (also known as the mother ship). After...
