Detailed Description

Firstly, the design initiatives of the invention are explained, in the structural characteristics of ships, a plurality of areas are closed or semi-closed, in the construction process of the ships, constructors need to enter the areas to work, at the moment, the constructors need to wind a large circle, construction tools are difficult to take in, and generally, the space has no illumination or ventilation, the construction environment is severe, the construction difficulty is large, so the safety risk is high, under the condition, temporary process holes are formed in the areas where equipment is searched or outfitting is less, so that the personnel can pass, the construction ventilation, the illumination and the like are facilitated, after the areas work, the process holes are plugged, the process holes are usually formed in the ship assembly or carrying stage, the process holes are formed at the moment, the process holes are usually formed by manual flame cutting, the cutting seams are uneven and are not attractive; the cut steel plate is placed in a nearby vacant position and is easy to lose; during later plugging, the cutting seam is uneven, the groove opening difficulty is high, and the groove gap is easy to be overlarge; in addition, multiple persons are required to cooperate during plugging, and plugging difficulty is high, so that the invention designs an operation method for opening the temporary process hole of the ship.

The invention is described in detail below with reference to the accompanying drawings, and as shown in fig. 1-2, a method for drilling a temporary process hole of a ship comprises the following steps:

the method comprises the following steps: drawing a hole opening track on a ship hull wall plate 1 needing hole opening; the hole opening track comprises a starting point 41 and a stopping point 42, the starting point 41 and the stopping point 42 divide the hole opening track into two sections, one section is a cutting track section 3, the other section is a cutting reserved section 4, and a cutting seam is formed after the cutting track section 3 is cut.

Step two: cutting the technical orifice plate 2 according to the drawn track; the technical hole plate 2 is cut by adopting a flame cutter, the cutting is started from a cutting starting point 41, the cutting is finished to a stopping point 42, a cutting reserved section 4 is not cut, the process hole is opened synchronously with the numerical cutting jacking, when the holes are opened by conventional numerical cutting, a small section of initial circular arc is arranged in each hole, and finally a small section of head-tail circular arc is arranged to ensure that the hole edge is completely cut, and the circular arc is canceled by the process hole and is directly started from a cutting seam.

Step three: forming a groove on the cutting track according to the requirements of a drawing; the groove is arranged on the cutting seam, the position and the size of the groove are arranged according to the drawing requirements, the groove is arranged at the moment, the difficulty is low, the efficiency is high, the quality of the groove is good, and if the cutting is carried out in the later stage of the slipway, the workload is large and the quality is difficult to guarantee.

Step four: manufacturing a hinge tool 5; the hinge tool 5 comprises two hinge eye plates 6, and the two hinge eye plates 6 are fixedly installed through the matching of bolts 7 and nuts 8.

Step five: welding the hinge tool 5; the hinge tool 5 is welded on a straight edge position far away from the cutting track section 3, so that the later normal opening and closing are ensured, during installation, the hinge tool 5 is arranged on a non-component surface, the subsequent normal use is facilitated, the two hinge tools 5 are welded on the technical hole plate 2 and the ship body wall plate 1, and the two hinge eye plates 6 of the hinge tool 5 are respectively welded on the technical hole plate 2 and the ship body wall plate 1.

Step six: cutting the reserved position of the fabrication hole to complete the opening of the fabrication hole; and cutting off the cutting reserved section 4, wherein a flame cutter is adopted in the process, and after cutting off, the technical orifice plate 2 is opened under the connection of the hinge orifice plate.

After the technical orifice plate 2 is used, the technical orifice needs to be blocked, in the process, the technical orifice plate 2 is closed and fixed through the Kama spot welding, then the groove is completely opened, and the subsequent processes of inspection reporting before welding, welding and inspection reporting after welding are completed.

And after the post-welding inspection reporting process is finished, cutting the clamping horse and the hinge tool 5, well recovering, polishing the welding leg and painting the welding seam.

Thus, the opening, the use and the plugging of the whole process hole are completed.
