Problems solved by technology

However, due to the large size of large ships, the height of the installation deck of the ROV-A bracket from the ceiling deck of the ship where the hanging code is set is usually greater than 10 meters. In the process of height adjustment, a lot of high-altitude operations are required, which is not only difficult, but also dangerous; in addition, a lot of work such as scaffolding needs to be built in the early preparation stage of hoisting, and it needs to be dismantled after the adjustment Post-processing work such as scaffolding, cutting and hanging codes, grinding and repairing not only requires a large workload, but also requires high proficiency of technical workers, and also has a long construction period, low construction efficiency, and high construction costs.

Embodiment 1

[0033] The precise adjustment and positioning method of the ROV-A support in this embodiment includes the following steps:

[0034] (1) if figure 1 As shown, the ROV-A bracket 6 is hoisted to the installation position inside the cabin 1 by a crane and initially positioned. Before the crane is removed, the gate-shaped card code 7 that prevents the ROV-A bracket 6 from toppling is used to base the ROV-A bracket 6. The seat 62 is fixed, and there is a gap between the door-shaped card code 7 and the base 62, and the door-shaped card code 7 does not limit the horizontal movement of the ROV-A support 6 along the bow and stern direction of the ship;

[0035] (2) if figure 2 As shown, two clamping plates 8 are set on the side of the base 62 close to the bow, and two clamping plates 8 are set on the side of the base 62 close to the stern, and the clamping plates 8 are fixed on the ship deck of the ship. 2, and there is a gap between the clamp plate 8 and the base 62 for placing the ...

Embodiment 2

[0048] The difference between this embodiment and Embodiment 1 is: in the process of fixing the base 62 on the side near the stern in the step (7), at the same time, the base 62 near the side is fixed by using the door-shaped card code 7 , in the process of slowly jacking up the base 62 near the bow side in the step (8), at the same time, the door-shaped card code 7 near the side direction is repaired, so as to achieve the height adjustment of the base 62 need.

[0049] Such as Figure 8 As shown, in the process of fixing the base 62 near the bow side in the step (9), at the same time, the door-shaped card code 7 is used to fix the base 62 near the side, and in the step (10) In the process of slowly jacking up the pedestal 62 near the stern side, at the same time, the door-shaped card code 7 near the side direction is repaired to meet the needs of the height adjustment of the pedestal 62.

[0050] Since the ROV-A support 6 and the ROV equipment 5 are very expensive, in order...

Abstract

The invention relates to a positioning and adjusting method, in particular to a precise ROV-A support adjusting and positioning method. According to the method, the ROV-A support adjusting and positioning process is conducted on a mounting deck of an ROV-A support, and no high-altitude work is needed, so that the working difficulty is lowered greatly, and safety is high. Furthermore, the precise ROV-A support adjusting and positioning method is used in match with a portal card code, a jack, a clamping plate and a thin jack, precise adjusting and positioning of the expensive equipment ROV-A support can be finished with matching of a crane and a calabash, the processes of building a scaffold, welding and cutting off a hoisting code, grinding, repairing and the like are avoided, the workload of the adjusting process is lowered, construction efficiency is improved beneficially, the construction cycle is shortened, and the high construction cost is lowered.

Description

technical field [0001] The invention relates to a positioning adjustment method, in particular to a precise adjustment and positioning method for an ROV-A bracket. Background technique [0002] In the field of ship technology, the cooperation and support of ROV equipment (unmanned remote control submersible) is required in the process of using multi-functional operation support ships for saturation diving operations, auxiliary installation of underwater flexible hoses, and hoisting of large underwater equipment. ROVs are usually placed Inside the cabin, its entry and exit are hoisted by the ROV-A bracket. The positioning accuracy of the ROV-A bracket is high during use. Usually, after the ROV-A bracket is hoisted into the corresponding installation position of the cabin by a crane, the positioning accuracy and height must be adjusted with hoisting tools to meet the final use. Require. [0003] In the prior art, in the process of adjusting the positioning accuracy and heigh...
