Problems solved by technology

In actual operation, the above-mentioned method of determining the three-dimensional coordinate points on the linear outer plate by using the horizontal hose, hammer, level ruler, etc. is difficult to operate, and the error of determining the three-dimensional coordinate points many times is relatively high, which affects the accuracy of opening and marking lines. Accuracy; in addition, drawing a large number of three-dimensional coordinate points on the linear outer plate is labor-intensive and takes a long time, which prolongs the ship's segment cycle

Embodiment Construction

[0024] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0025] For the convenience of those skilled in the art to understand and better understand this scheme, the following definitions are made to the side thruster, side thruster tube and deflector:

[0026] The side thruster, that is, the bow thruster, is a special thruster installed on the bow of the ship, which is used to improve the maneuverability of the ship and accurately maintain the ship's position. It is used on offshore engineering ships and ferries.

[0027] Thruster tube, the round tube through which the water flows in the bow thruster.

[0028] The deflector, the side thrust tube and the outer plate connecting plate, are used to guide the water flow through the side thrust tube and reduce the water flow resistance at the joint be...

Abstract

The invention discloses a hull side thruster guide plate scribing instrument and a drilling and scribing method thereof and relates to a drilling and scribing device. The hull side thruster guide plate scribing instrument comprises a laser dotter and a support mechanism, wherein the support mechanism comprises a supporting group frame, a central shaft rod, a rotating bracket and a laser dotter support. One end of the central shaft rod is fixed on the supporting group frame, and the other end of the central shaft rod is provided with a rotating support. One end of the laser dotter support is fixed on the rotating support, a tray is arranged at the other end of the laser dotter support, the laser dotter is installed on the tray, and the laser dotter support is perpendicular to the central shaft rod and can rotate around the central shaft rod through the rotating support. The scribing accuracy during outer plate drilling can be improved, the operation difficulty during outer plate drilling and scribing is reduced, shortening of the scribing time is facilitated, and a segmented period is shortened.

Description

technical field [0001] The invention relates to a hole-drilling and marking device, in particular to a hull side thruster deflector marking instrument for determining a theoretical line for opening a hole on a hull side thruster deflector and a method for marking a hole. Background technique [0002] At present, the marking line on the deflector plate of the hull side thruster is generally determined by using a horizontal hose, hammer, level gauge, etc. to determine the three-dimensional coordinate points on the linear outer plate, and draw the opening line after smoothing with splines. In actual operation, the above-mentioned method of determining the three-dimensional coordinate points on the linear outer plate by using the horizontal hose, hammer, level ruler, etc. is difficult to operate, and the error of determining the three-dimensional coordinate points many times is relatively high, which affects the accuracy of opening and marking lines. Accuracy; in addition, drawi...
