Description

Technical Field

[0001] The present application relates to the field of linear shape detection technology, and in particular to a method for rapid linear shape detection of pressure-bearing wood of a C-type liquid tank. Background Art

[0002] In the industrial field, liquid tanks often adopt cylindrical structures. To ensure the safe operation of liquid tanks, arc-shaped pressure-bearing wood is usually installed at both ends of the liquid tank to enhance the structural strength. After the installation of these pressure-bearing wood, linear measurement is required to ensure that the matching line with the liquid tank saddle meets the design requirements, so as to ensure that the liquid tank has good stability and safety when under pressure. This on-site measurement work is crucial to the integrity and operational stability of the liquid tank structure, and provides important guarantees for engineering construction and liquid tank operation safety.

[0003] Currently, measurements are generally made using a tape measure and plumb bob. However, due to the large linear shape of the bearing wood, the actual measurement process results in large deviations in the measurement position and inaccurate data. Summary of the invention

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0028] The following is combined with Figure 1-3 This application is described in further detail.

[0029] The present application embodiment discloses a method for quickly detecting the linear shape of a C-type liquid tank pressure-bearing wood. Figure 1 , Figure 2 A C-type liquid tank pressure wood linear rapid detection method includes the following steps, namely:

[0030] S10: Determine the centerline projection 11 of the liquid tank, the transverse centerline projection 12 of the fixed wooden block, and the transverse centerline projection 13 of the sliding wooden block at a plane position. In some embodiments, the centerline projection 11 of the liquid tank, the transverse centerline projection 12 of the fixed wooden block, and the transverse centerline projection 13 of the sliding wooden block can be marked directly on the ground. The liquid tank 1 is placed on the ground through a supporting structure, and the central axis of the liquid tank 1 is flush with the ground, and a distance is left between the lowest end of the liquid tank 1 and the ground.

[0031] The midpoint of the transverse centerline of the fixed wooden block is the point closest to the ground, so that the distance between the midpoint of the transverse centerline of the fixed wooden block and the ground is the minimum distance; the midpoint of the transverse centerline of the sliding wooden block is the end closest to the ground, so that the distance between the midpoint of the transverse centerline of the sliding wooden block and the ground is the minimum distance, and the minimum distances of the two are the same, so that the liquid tank 1 is set in parallel.

[0032] S20: A plurality of first points 2 are equally divided on the transverse centerline projection 12 of the fixed wooden block, and the distance between two adjacent first points 2 is the same; a plurality of second points 3 are equally divided on the transverse centerline projection 13 of the sliding wooden block, and the distance between two adjacent second points 3 is the same.

[0033] In some embodiments, the intersection of the horizontal centerline projection 12 of the fixed wooden block and the centerline projection 11 of the liquid tank is taken as the first reference point 21, and the plurality of first points 2 extend from the first reference point 21 to both sides of the reference line. The intersection of the horizontal centerline projection 13 of the sliding wooden block and the centerline projection 11 of the liquid tank is taken as the second reference point 31, and the plurality of second points 3 extend from the second reference point 31 to both sides of the reference line.

[0036] The above-mentioned S30 may include the following steps:

[0037] S31: vertically project the first point 2 onto the pressure-bearing wood to form a first projection point 23, and vertically project the second point 3 onto the pressure-bearing wood to form a second projection point 33. The distance between the first point 2 and the first projection point 23 is measured as H. 1 , by measuring the distance between the second point 3 and the second projection point 33, H 2 .

[0038] The vertical direction setting for the first projection point 23 and the second projection point 33 can be achieved by using a laser projector, placing a laser level at the first point 2, using the laser point of the laser level as the absolute horizontal reference, and the laser point of the laser level is the first projection point 23. Placing the laser level at the second point 3, using the laser point of the laser level as the absolute horizontal reference, and the laser point of the laser level is the second projection point 33.
