A lifting device for assembling ship bottom plate and cladding strip

Abstract

The invention discloses a lifting device used for the assembling of a boat bottom plate and a doubling plate bar. The lifting device comprises an air cushion, wherein the surface of the air cushion isprovided with a first bottom plate; a hollow boss is welded to the surface of the first bottom plate; a vacuum groove is independently arranged on four edges and the middle of a contact area of the surface of the hollow boss and the doubling plate bar; the side surface of the hollow boss is provided with a hole for connecting with one end of a flexible pipe, and the other end of the flexible pipeis connected with a vacuum pump; and the bottom of the air cushion is provided with an air inlet and an air outlet, wherein the air inlet is connected with one end of an air inlet pipe, and the otherend of the air inlet pipe is connected with an air pump. The lifting device used for the assembling of the boat bottom plate and the doubling plate bar has good universality, has a simple structure,is convenient in use and can reduce an assembling gap between the boat bottom plate and the doubling plate bar, meanwhile, the stability of the doubling plate bar in a lifting process can be guaranteed, and a situation of accidently falling is avoided.

Description

technical field [0001] The invention relates to the technical field of lifting devices, in particular to a lifting device used for assembling ship bottom plates and cladding strips. Background technique [0002] In recent years, my country's foreign trade has grown rapidly, and China has become an important manufacturing base in the world, in which a large number of goods need to be shipped by sea. The lengthening of the ship, changing the navigation area, or the corrosion and thinning of the structure during operation may lead to insufficient longitudinal strength of the ship. Adding cladding strips at the bottom of the ship is a common method to increase the longitudinal strength of the ship. The specific method is to place cladding strips of a certain width under the bottom of the ship to connect them to the bottom of the ship. The advantage of adopting this method is that it will not damage the original structure of the ship, nor will it cause inconvenience to the crew....

AI Technical Summary

Problems solved by technology

The main problem of this construction method is: after all the cladding strips are tightened by the hand chain hoist, there will be a gap of about 500mm; moreover, each cladding strip needs to be pre-welded with lug plates, and the work efficiency is low
