Embodiment Construction

[0029] The installation method of the large-scale movable ramp of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention cannot be limited by this.

[0030] In the large-scale activity ramp installation method of the present invention, in figure 1 The structural accuracy measurement is carried out under the state. Then retest the accuracy of the active ramp 1 to master the ramp accuracy data. Lap joint tooling 2 is installed, and the movable ramp 1 is hoisted into the opening of the hull structure. The movable ramp hinge 5 is installed and restrained and fixed. Lift the movable ramp 1 and the lap joint tool 2 together in situ, put them on the round pipe 3, carry out the operation in the blind area of ​​the movable ramp, and install the adjusting gasket.

[0031] Specific steps such as Figure 5 as shown, Figure 5 It is a schematic diagram of ...

Abstract

The invention relates to a mounting method for a large movable ramp. The method comprises the following steps that the movable ramp and a hull structure are measured; a lap joint tool is welded to the movable ramp, and the ramp is in lap joint with an opening of the structure; a centre drawer hinge bracket connected with a hull is assembled; the position of the movable ramp is determined, after other accessories are mounted and positioned, the gap between the ramp and a supporting base is measured, and an adjusting gasket is machined; and the movable ramp is hoisted, a lap joint plate is in lap joint with a round pipe, repair welding is conducted on a blind spot in hinge welding, the ramp is started, and the adjusting gasket is welded. Through the method, the ramp can be mounted with high precision, and the special tool is used so that the lap joint requirement can be met and movable adjustment can be achieved during adjustment. Labor intensity is relieved, and meanwhile mounting quality is improved.

Description

technical field [0001] The invention relates to ship construction, in particular to a method for installing a large-scale movable ramp in the construction of a container ro-ro ship or a ro-ro ship. Background technique [0002] At present, the installation of large-scale movable ramps in the construction of large container ro-ro ships or large ro-ro ships mainly uses the following methods: [0003] 1. After the hull is completed, the movable ramp is hoisted into the structure, and the surrounding is welded and fixed with brackets. [0004] 2. Adjust the position of the ramp and the position of the structural opening, and trim and match. [0005] 3. The hinge is installed separately, which is convenient for welding, but the welding deformation is difficult to control. It is difficult to penetrate the hinge pin in the later stage, and it needs to be pressed in forcibly, and there will be a lot of stress inside. [0006] 4. After the hinge is installed, it is necessary to use...
