Description
Technical Field
The invention relates to the technical field of measuring tools of ship structures, in particular to a measuring scale for a ship structure.
Background
At present, the measuring scale is widely used for precision measurement of ship assembly (including welding) of a ship structure, wherein the ship structure comprises a veneer part and a component splicing plate. A common measuring tape is a tape measure.
Before welding operation, a 150mm (millimeter)/100 mm positioning reference line needs to be scribed on a whole steel plate, and taking scribing on a single steel plate as an example, the scribing process of the positioning reference line is as follows:
1. and taking points which are parallel/vertical to the edge of the steel plate and are 150mm/100mm away from the edge on two sides of the whole steel plate, and drawing a connecting line for connecting the two points to generate a positioning datum line.
Referring to fig. 1, where points A, B, C, D are points 150mm from the edges of the steel plate, respectively, positioning reference lines AB and CD should be parallel to the two sets of steel plate edges, respectively, and point O is the intersection of the positioning reference lines AB and CD.
In the process, a square and the like are needed to be matched with the tape measure for marking, the process is complicated, and errors are easy to generate.
2. Taking a point E on the point AB, wherein the length OF OE is 9 meters, taking a point F on the point CD, wherein the length OF OF is 12 meters, measuring the length OF EF, checking whether the length OF EF is equal to 15 meters, namely whether the lengths OF OE, OF and EF meet the Pythagorean theorem, and if so, indicating that the point AB and the point CD are mutually vertical and meeting the precision requirement OF positioning datum line scribing; if the pythagorean theorem is not met, re-scribing is needed until the two groups of positioning reference lines are mutually perpendicular (namely, the check shows that the pythagorean theorem is met) and one positioning reference line is parallel to the edge of the steel plate.
Wherein, the lengths OF OE, OF and EF can take other values as long as OE: OF: EF satisfies 3: 4: 5, the product is obtained.
3. And according to the assembly drawing, sequentially drawing all structure assembly lines parallel to the positioning datum line from the positioning datum line according to the spacing distance. Wherein the structural assembly line has hundreds of pieces.
Referring to fig. 2, A1B1 is a parallel assembly structure line closest to the positioning reference line AB, the assembly structure line A1B1 is drawn according to the spacing distance on the assembly drawing with AB as a reference, the assembly structure line A2B2 is drawn according to the spacing distance on the assembly drawing with A1B1 as a reference, and so on until the assembly structure line AmBm farthest from AB is drawn. Wherein A1B1 and AmBm may not be located on the same side of AB, and m is an integer greater than 1.
Similarly, assembly structure lines C1D1 to CnDn are drawn in the other direction in turn, n being an integer greater than 1.
When large-batch short interval distance (within 150 mm) is marked, a square ruler and the like are used for marking in cooperation with a measuring tape, and the marking efficiency is low.
4. And drawing a positioning reference line opposite to the positioning reference line determined in the step 2.
Namely, drawing a positioning datum line JK by taking an assembly structure line AmBm as a reference according to the spacing distance on an assembly drawing; and marking out a positioning datum line HG by taking the assembly structure line CnDn as a datum according to the spacing distance on the assembly drawing.
5. After scribing is completed, verification according to an assembly drawing is required.
In addition, in the case of measuring on a solid member, it is inconvenient to measure using a tape measure.
After the structural members are welded, whether the distance between the edge of the structural member welded on the positioning datum line and the edge of the steel plate is 150mm/100mm or not needs to be verified, namely whether the positioning datum line meets the precision requirement or not, and whether the short spacing distance (within 150 mm) between the structural members meets the precision requirement or not needs to be verified. The tape measure is inconvenient to verify in such situations.
In addition, the scale marks of the measuring tape are easy to wear and are worn quickly.
