Description
Technical Field
The invention relates to the field of ship building tools, in particular to an integral hoisting system of a movable weather shed.
Background
Some important ships all have strict welding environment requirement in whole manufacturing process, can use when the hull segmentation is made on the slipway to build better similar indoor environment with removing the weather shed, but when the segmentation was assembled in the dock, can't use and remove the weather shed and build better indoor environment. In order to create an indoor-like welding construction environment, when construction welding is performed in a dock, a temporary shelter is generally built at a construction point for a certain period of time. However, the total assembly time of the segments is long, the size of the ship body is large, and the temporary shielding part needs to be built and dismantled repeatedly, so that the production efficiency is seriously influenced, and the manufacturing period of the ship body is prolonged. If the movable weather shed can also be used in the dock, a shielding part does not need to be temporarily built, the production efficiency is improved, and the manufacturing period of the ship body is shortened.
The existing movable wind and rain shed can only move on a specific group of tracks on a slipway and does not have the function of moving. Even if the platform can be moved, the platform can be moved to another slipway from one slipway track integrally by using a trolley and spending a large amount of manpower and material resources under the condition that the height of the terrace is not large. However, when the terrace is very different, the height difference between the track of the berth and the track of the dock of a common shipyard is often 10m to 15m, which means that the small vehicle cannot be used for moving the whole wind and rain shed. If the conventional movable wind and rain shed is integrally hoisted by using a crane in a shipyard, the movable wind and rain shed can be greatly deformed after being hoisted, so that the wind and rain shed cannot run on a preset track. In addition, if the upright columns of the conventional wind and rain shed are transversely fixed and then hoisted and moved, but a whole ship or a ship body is often paved in the dock, and the wind and rain shed after transverse fixing cannot be placed in the dock. Therefore, the conventional movable weather shed cannot be used in the dock.
