Integral hoisting system for movable shelter

Abstract

The invention discloses an integral hoisting system for a movable shelter and relates to the field of ship building tooling. The integral hoisting system comprises a movable shelter assembly, suspensory riggings, a hoisting assembly, a crane and drawing devices, wherein the movable shelter assembly comprises a roof, supports, shelter lifting lugs and auxiliary pulling lugs; the tops of the two supports are fixedly connected to the two sides of the roof respectively; the shelter lifting lugs are fixedly connected to the top of the roof; the auxiliary pulling lugs are fixedly connected with thebottoms of the two sides of the two supports; lifting hooks are arranged at the top of the crane, and are connected with the shelter lifting lugs; the drawing devices are arranged on the two sides ofeach support; the auxiliary pull lugs are connected with the drawing devices located on the same side through the hoisting assembly. According to the movable shelter system capable of moving between adock and a shipway, integral moving between the shipway and the dock can be realized without temporary construction of a shelter, production efficiency is improved, the hull fabrication cycle is shortened, and the system can still operate on preset tracks after movement.

Description

technical field [0001] The invention relates to the field of ship construction tooling, in particular to an integral hoisting system for a mobile shelter. Background technique [0002] Some important ships have strict welding environment requirements during the whole manufacturing process. When the hull sections are manufactured on the berth, mobile shelters can be used to create a better similar indoor environment, but when the sections are assembled in the dock, they cannot Use mobile shelters to create a better indoor environment. In order to create a welding construction environment similar to indoors, when construction welding is carried out in the dock, a temporary shelter is usually built at a certain construction point within a certain period of time. However, due to the long assembly time of the sections and the large size of the hull, the construction and dismantling of the temporary shelter needs to be repeated, which seriously affects the production efficiency a...

Problems solved by technology

Even if it can be moved, it will take a lot of manpower and material resources to move from one berth track to another berth track by using a trolley under the condition that the height of the floor is not much different.

However, there is a large difference between the ground and the height of the berth track and the dock track of the general shipyard are often 10m ~ 15m, which is impossible to use the trolley to move the shelter as a whole.

If the conventional mobile shelter is hoisted by the crane in the shipyard as a whole, the mobile shelter will be deformed after hoisting and the shelter will not be able to run on the preset track

In addition, if the columns of the conventional shelter are horizontally fixed and then hoisted and moved, but often the dock is covered with a whole ship or hull segments, the horizontally fixed shelter cannot be placed in the dock

Therefore, the current conventional mobile shelters often cannot be used in the dock
