Abstract

The present invention discloses a method for checking the simulated allowance cutting of the reverse member. This method uses a device for checking the simulated allowance cutting of the reverse member to measure the simulated allowance cutting of the main board and the member at different angles, and based on the measurement data, re-cut the non-compliant parts or give an early warning for the subsequent segmented hoisting of other components to avoid the problem of board replacement.

Description

Technical Field

[0001] The present invention belongs to the technical field of shipbuilding, and particularly relates to a method and device for inspecting the simulated allowance cutting of reverse members. Background Art

[0002] Before the lifting of sub-assemblies / blocks, simulated overall assembly / lifting measurements are carried out, and the simulated allowances are cut before the lifting of sub-assemblies / blocks, so as to reduce the cutting during the lifting of sub-assemblies / blocks and shorten the lifting time.

[0003] In the past, when simulating allowance marking, there were dedicated personnel responsible for marking the main plates. The main plates include outer plates, decks, platform plates, inner bottom plates, inner longitudinal bulkheads, etc. Then, the cutting personnel were responsible for cutting according to the lines, and the cutting quality was basically controllable. Due to factors such as a large number of members, short lengths, and the fact that some reverse top members of the main plates do not have the conditions for marking, there were no dedicated personnel for marking, and the cutting personnel cut by referring to the cutting edges of the main plates themselves, and the quality could not be guaranteed.

[0004] To check whether the simulated allowance cutting of the members meets the specification requirements, it is necessary to quickly complete the 100mk lines on the members with allowance cutting within an extremely short time before the block lifting, sometimes only 1-2H, and determine whether the simulated allowance cutting of the members meets the specification requirements through measurement. It is very difficult to achieve under the existing technical conditions. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies existing in the above-mentioned prior art, and provide a method and device for inspecting the simulated allowance cutting of reverse members. The method and device of the present invention fix the marking rod on the main plate through the provided card slot, and realize marking the 100mk line and cutting line on the member through the angle turntable and telescopic rod, and determine whether the simulated allowance cutting of the member meets the specification requirements through measurement, realizing the measurement of the simulated allowance cutting of the member at different angles between the member and the main plate, improving the measurement accuracy, and shortening the construction period.

[0006] In order to achieve the above-mentioned invention purpose, the technical solution provided by the present invention is as follows:

[0007] A method for inspecting the simulated allowance cutting of reverse members, the method specifically includes the following steps:

[0008] The first step is to prepare a device for inspecting the simulated allowance cutting of reverse members.

The guide rail drives the angle turntable to rotate. The marking rod is installed on the telescopic rod, and a first marker pen and a second marker pen are arranged on the side of the marking rod;

[0009] In the second step, select a point on the root main board of the component after the simulated allowance cutting is completed, and fix the card slot on the root main board;

[0011] In the fourth step, the telescopic rod moves telescopically on the guide rail, and the telescopic rod drives the scribing rod to move so that the first marker pen and the second marker pen on the scribing rod respectively scribe a 100mk line and a cutting line on the end face of the component;

[0012] In the fifth step, after scribing is completed, measure whether the distance between the actual cutting line of the component and the 100mk line scribed on the end face of the component meets 100mm, so as to check whether the simulated allowance cutting of the component meets the specification requirements.

The first marker pen and the second marker pen are respectively placed in the fixing columns, and the first marker pen and the second marker pen are respectively fixed in the fixing columns by bolts and spring piece clamps; the distance between the first marker pen and the second marker pen is 100mm.

[0017] The above-mentioned first marker pen is used to scribe a 100mk line, and the second marker pen is used to scribe a cutting line.

[0018] In the above-mentioned fifth step, specifically check whether the distance between the actual cutting line of the component and the 100mk line drawn on the end face of the component meets 100mm. That is: when the distance between the actual cutting line of the component and the 100mk line exceeds 100mm, then cut along the drawn cutting line until it is exactly sufficient; when the distance between the actual cutting line of the component and the drawn 100mk line is less than 100mm, then give an early warning for the subsequent segmented hoisting of other components to prevent the component gap from exceeding the standard and causing plate replacement.
