Water lifting platform

Abstract

The invention discloses a water lifting platform, which comprises a base and a framework arranged on the base, and is characterized in that: an airbag conveying device is arranged in the framework, and comprises an airbag arranged at the bottom of the framework and a lifting platform connected with the upper end of the airbag; the airbag is a multi-layer airbag or a folding airbag; the lower part of the airbag is provided with an airbag inlet / drain valve, and the upper part of the airbag is provided with an airbag intake / exhaust valve; the lifting platform is provided with a platform inlet / drain valve and a platform intake / exhaust valve; the framework comprises upright posts and beams, and is provided with an inlet / outlet; the upper end of the framework is provided with a truss or hoisting equipment; and each upright post is provided with a supporting piece seat and a supporting piece. In the whole working process, the energy consumption is low, the efficiency is improved, risks are reduced, and the construction is more convenient and quick.

Description

technical field [0001] The invention relates to mechanical equipment for underwater construction, in particular to an underwater lifting platform for launching large components into the water. Background technique [0002] At present, in construction projects such as ports, bridges, tunnels, and power plants, or in the shipbuilding industry, it is often necessary to launch large components such as caissons, immersed tubes, casings, cofferdams, box culverts, and ship sections. The current common method is to transport these components to semi-submersible ships or floating docks, or to directly manufacture them on semi-submersible ships, and then to submerge the semi-submersible ships or floating docks to send the components into the water. These components are huge in shape, ranging from hundreds of tons in the lightest weight to thousands or even tens of thousands of tons. The semi-submersible ships or floating docks and supporting tugboats and other marine equipment are ver...

AI Technical Summary

Problems solved by technology

These components are huge in size, ranging from hundreds of tons in weight to thousands or even tens of thousands of tons. The semi-submersible ships or floating docks and supporting tugboats and other marine equipment are very large, and the cost of launching components is expensive.

Taking a caisson with a height of 20 meters, an area of ​​240 square meters, and a weight of 2,000 tons as an example, the comprehensive cost of launching it with a semi-submersible ship or floating dock is more than 250,000 yuan, and the launching operation is very complicated. Hours, time-consuming and risky, construction cannot be carried out in case of slightly larger wind and waves
