Problems solved by technology
[0006] The advantage of the present invention is that it overcomes the cumulative influence of the errors in the production, installation and welding of components in the past on the installation of the stern door hinge, and the risk that the dummy shaft cannot be disassembled due to the interference of the dummy shaft inserted into the hinge ear plate due to post-welding cooling. In order to solve the deficiencies, a method for controlling the installation accuracy of stern door hinges is provided. This method is suitable for the installation of two or more sets of hinges for small, medium and large stern doors, hatch covers, and springboards with regular shapes. The installation method is simple and the accuracy is higher. easy to guarantee

Embodiment Construction
[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0042] like Figure 1-Figure 11 A method for controlling the installation accuracy of the stern door hinge is shown, including the following steps:
[0043] A. Preparations before installation: ① Before lowering the tire frame, use the method of projection of the vertical line to describe the inspection center line of the stern door; ② Eliminate the welding stress during the production of the stern door body after the tire frame; Work correction;
[0044]B. According to the theoretical data of the drawing, draw the ground sample reference line on the horizontal ground: the reference line includes the theoretical center line of the stern door and the theoretical longitudinal center line of the hinge. , the horizontal theoretical center line of the left and right hinges, the horizontal theoretical center line of the hinge and the theoretical center line o...

The invention discloses a method for controlling the installation accuracy of a stern door hinge, including A. preparatory work before installation, B. drawing a ground sample reference line on the horizontal ground according to the theoretical data of the drawing, and C. hoisting the stern door to a designated position: using a crane to lift the stern door Hang it to the pier on one side of the ground sample datum line; D. Select the horizontal measurement point of the stern door; E. Check the accuracy of the theoretical center line and describe the positioning line of the transverse center line of the hinge; F. Describe the horizontal installation line of the hinge; G. Process and install the dummy shaft and short casing; H, adjust the longitudinal position of the dummy shaft; I, adjust the transverse center position of the hinge seat plate; J, install the hinge seat fixing gasket; K, measure and prepare the adjusting gasket; L, point Welding the adjusting gasket; M, drilling, tapping and fixing the hinge seat; N, installing the hinge seat; O, welding the adjusting gasket; P, removing the dummy shaft, and installing the hinge pin. The invention is applicable to the installation of two or more sets of hinges for stern doors, hatch covers and springboards, and has a simple installation method and high precision.
Description
technical field [0001] The invention belongs to the technical field of ships, in particular to a method for controlling the installation precision of a stern door hinge. Background technique [0002] Large ships are usually equipped with 1-2 high-speed boats as working boats to make up for the lack of large hulls that cannot perform tasks in shallow water areas. The traditional small boat retractable and retractable device is generally retracted and retracted by a crane, which is not only slow, but also not safe enough, so the stern slide technology came into being. The stern slide technology first appeared abroad. At present, only a small number of domestic companies have this technology, which is mainly used in military ships and official ships with high functional requirements. [0003] Military ships and official ships are generally long in structure and heavy in weight. Hinges are designed between the stern door, the springboard and the hull. The weight of the hinges i...
