Abstract

The invention provides a moon pool rail manufacturing method. The moon pool rail manufacturing method includes the following steps that according to the size design requirements, various parts of a moon pool rail are produced, wherein the parts include first angle steel, a round pipe, main struts, auxiliary struts and diagonal struts; several position points are marked on the round tube, and corresponding marking lines are drawn; more than 3 main struts with one arc-shaped ends are manufactured, the two end points of the arc edges of the main struts are welded to the round pipe along the marking lines on the round pipe, and the main struts are welded to the round pipe at an equal distance; the first angle steel is welded to the round pipe along the marking lines on the round pipe; more than six auxiliary struts are manufactured, the auxiliary struts are welded to the two sides of the main struts along the marking lines on the round pipe correspondingly; and the diagonal struts are installed. The first angle steel designed by the moon pool rail manufacturing method is matched with a sliding-moving device on a diving bell, and the problem of retracting and putting of the diving bellis successfully solved; and the moon pool rail is further provided with the main struts, the auxiliary struts and the diagonal struts for supporting the first angle steel to enable the moon pool railto be more stable.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a method for making a moon pool track. Background technique [0002] Saturation diving technology is the cutting-edge technology of deep-sea operations. It is currently widely used in military and civilian fields such as rescue of wrecked submarines, submarine construction operations, underwater resource exploration, and marine scientific investigations. In order to carry out deep-sea operations, it is necessary to send personnel into the deep sea through the moon pool through the diving bell. In order to ensure the safety and convenience of lowering and recovery, a square opening called a moon pool is usually set up on the deck of the ship, which runs through the bottom plate from the main deck. In order to ensure that it can pass through the moon pool smoothly when retracting, it is necessary to set a track in the moon pool so that it can move up and down along the t...
