Problems solved by technology

The existing technology is to use a crane to lift the hatch cover. This solution requires the crane to cooperate with the lifting of the hatch cover. There are 7 hatch covers in the whole ship, and the hatch covers are lifted frequently. Moreover, the crane resources at the wharf are very tight. The installation of the cover has a great impact on the entire system. Therefore, it is necessary to invent a method that can reduce the number of times the crane is used to hoist the hatch cover, meet the requirements of the hatch cover oil cylinder hoisting, and also meet the requirements of the hatch cover outfitting operation.

Embodiment Construction

[0027] refer to Figure 1 to Figure 6 , the present invention is a hatch cover jacking moving method, which comprises the following steps:

[0028] S1: Design jacking tooling 1, moving tooling 2, and sliding trolley 3. Before the hatch cover 4 is on board, hoist the lower ear plate of the hatch cover hinge and the dummy shaft-like rod into the oil tank cabin. Specifically, the mobile tooling 2 includes a guide rail 21 and a support pier 22 , the guide rail 21 is spot welded and fixed on the hatch coaming 5 , and the support pier 22 is installed at the bottom of the hatch cover 4 . The jacking tool 1 includes a jacking oil top 11 and a jacking platform 12, the jacking platform 12 is installed at the lifting lug position of the hatch cover, and the jacking oil top 11 is installed on the hatch coaming and the jacking platform 12. Between pallets 12. Among them, the lifting tooling 1 and the moving tooling 2 are welded with GFL-71 welding rods, and all welding legs are ≥7mm; aft...

Abstract

The invention discloses a hatch cover jacking and moving method. By designing a simple jacking tool, a moving tool, and a sliding trolley, and through the mutual cooperation of the three, the sliding trolley is dragged by a code to move along the guide rail of the moving tool to move the cabin. The cover is easy to install and operate on site, and it reduces the hoisting of the hatch cover, relieves the resources of the wharf crane, and can well meet the hoisting of the oil cylinder. This invention is used in the field of hatch cover installation and movement.

Description

technical field [0001] The invention relates to the field of hatch cover installation and movement, in particular to a hatch cover jacking and moving method. Background technique [0002] At present, the hatch cover of the 1400TEU container ship built by our factory is hinged, and the jacking cylinder of the hatch cover is arranged under the hatch cover. The weight of a single jacking cylinder is about 1 ton, and the weight of the hatch cover is about 82 tons. After the hatch cover is hoisted onto the ship, the outfitting on the hatch coaming should be installed first, but the jacking cylinder cannot be placed in the cabin in advance, so the hatch cover needs to be hoisted and removed first, and then the jacking cylinder should be hoisted in. In the cabin, finally lift the hatch cover back to its original position. The existing technology is to use a crane to lift the hatch cover. This solution requires the crane to cooperate with the lifting of the hatch cover. There are 7...
