Embodiment Construction

[0050] The present invention will be described in detail below with reference to the accompanying drawings.

[0051] Refer to attached figure 1 - attached Figure 22 ,

[0052] A method for installing and detecting a lifting fin guide rail, comprising the following steps:

[0053] First, check the data of the surrounding well 50. The surrounding well 50 is spliced ​​by different segments. Check whether the accuracy and length of these segments are within the range of error requirements. 51 is marked and fixed on the inner wall of the well 50 by spot welding. Between the support plates 51, steel pipes or angle steels are used to ensure the relative distance between the support plates, and the distance between the support plates and the ship’s reference line is measured. Whether the difference between the actual value and the design value is between -2mm and 0mm, within the error range, the support plate 51 is welded and fixed on the inner wall of the enclosure 50;

Abstract

The invention relates to a method for installing and detecting a lifting flipper guide rail. The method for installing and detecting the lifting flipper guide rail comprises the following steps that the data of a trunk are checked, whether the precision and the length after the trunk is mounted in sections are within the error requirement range or not is checked, the guide rail is welded to a guide rail connecting plate together, the guide rail is hung into the trunk, the guide rail is arranged on a supporting plate, an adjusting bolt is arranged on a bracket temporarily welded on the inner wall of the trunk, the position of the guide rail is adjusted through the adjusting bolt, the sizes of L, L1, L2, H, H1 and H2 are measured, and compared with design values, if the size exceeds 2mm, theguide rail is adjusted up and down until the error range is within 2mm; a tool is disassembled, the guide rail is fixed by the adjusting bolt, spot welding is carried out on the guide rail connectingplate and the supporting plate, and then the guide rail connecting plate and the supporting plate are welded; and the tool is used for recheck to ensure the normal installation of the guide rail. Byusing the method for installing and detecting the lifting flipper guide rail to measure a bow and a stern of a measuring tool, the installation precision and quality of the guide rail are improved, and the production efficiency in the shipbuilding process is improved.

Description

technical field [0001] The invention relates to the field of ship equipment installation, in particular to an installation and detection method of a lift fin guide rail. Background technique [0002] At present, in the construction process of fishery survey ships, the installation and commissioning of elevating fins is an important task, among which, the installation of elevating fin guide rails is the core work inside. During the installation process of the lifting fin guide rail, it is necessary to check whether the installation dimensional accuracy meets the specified requirements before welding and fixing, and some tooling will be used to assist the construction. Using the original installation and inspection methods of lift fin guide rails, many processes are measured by drawing steel wires and ordinary rulers, which is difficult, time-consuming, and low-precision. Contents of the invention [0003] In order to solve the problem of low precision, time-consuming and l...
