Problems solved by technology

[0009] 1. X-ray equipment is complicated and expensive;
[0010] 2. Many people are required to cooperate with the operation, which is inconvenient;
[0011] 3. X-rays have radiation biological effects on the human body and are harmful to human health; during X-ray filming operations, unrelated personnel are prohibited from approaching within a certain range around it, resulting in the inability to carry out other operations on nearby ships and affecting the overall production progress;
[0012] 4. This method consumes too long time from placing the reference object to finally determining the location of the r

Embodiment Construction

[0042] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0043] Such as Figure 1 to Figure 2 As shown, the present invention uses ultrasonic thickness measurement to locate the method for strengthening the reverse surface of the ship, comprising the following steps:

[0044] S1: On the smooth surface of the hull plate 2, a strip-shaped estimated strengthening section corresponding to the reinforcement 1 position on the opposite side of the hull plate is divided;

[0045] S2: Draw two spaced measurement lines perpendicular to the strip-shaped estimated strengthening interval, which are the first measurement line and the second measurement line;

[0046] S3: apply coupling agent for ultrasonic thickness measurement at the first measurement line and the second measurement line;

[0047] S4: Turn on the ultrasonic thickness gauge 3 and adjust to the steel material thickness measurement mode;

Abstract

The invention discloses a method for positioning a reverse reinforcing structure of a ship by adopting ultrasonic thickness measurement, which relates to the field of ship construction and comprises the following steps of: dividing strip-shaped estimated reinforcing intervals on a smooth surface of a ship body plate; measuring the thickness of the ship body plate by using an ultrasonic thickness gauge perpendicular to the strip-shaped pre-estimation reinforcing interval, recording a first point position and a second sudden change corresponding to the sudden change of the thickness measurement reading of the ultrasonic thickness gauge on the smooth surface of the ship body plate, and then changing the position and repeatedly measuring in the same direction to obtain a third point position and a fourth point position; a first straight line is drawn through the first point position and the third point position, a second straight line is drawn through the second point position and the fourth point position, and the area between the first straight line and the second straight line is the accurate alignment position of the hull plate back reinforcement on the hull plate smooth surface. Compared with the prior art, the method provided by the invention is more accurate and rapid in positioning, simpler in operation and lower in cost of related used equipment.
