Embodiment 1
[0035] Embodiment 1: A method for modeling the deformation of pressure-bearing special equipment. First, a tool with multiple pressure detection components arranged in a lattice is required, such as figure 2 and image 3 As shown in the tool, the tool also includes a magnetic traveling wheel assembly 3 and a camera assembly 5 .
[0036] The magnetic travel wheel assembly 3 can ensure that the tool always travels along the outer surface of the pressure vessel, thereby ensuring that multiple pressure detection assemblies travel synchronously. Such as Figure 8 As shown in , shaft perforations 22 are set at three points around the tool and the magnetic travel wheel assembly 3 is fixedly installed. Each magnetic walking wheel assembly 3 includes a columnar magnetic roller 31, the axle center of which is installed on the roller frame 33 by the roller shaft 32, and the upper center of the roller frame 33 is vertically fixed with a support bar 34, and the support bar 34 runs throu...
Embodiment 2
[0041] Embodiment 2: On the basis of Embodiment 1, the camera components involved in the tool include cameras A1 and A2 located on the left and right sides, and camera B located at the front or rear. Cameras A1 and A2 are used to capture all pressure detection Components and their peripheral images. Camera B is used to capture and cut images within the range of pressure detection components. Cameras A1 and A2 are mainly used for image acquisition of the connecting parts of 3D modeling. Camera B is mainly used for 3D modeling. Data correction image acquisition.
[0042] Among them, the processing of image information collected by the camera component and the process of 3D modeling also include collecting RGB images of pressure vessels, using RGB images and depth image information to form point cloud data, and mapping pixels from two-dimensional space to three-dimensional space.
Embodiment 3
[0043] Embodiment 3: A tool for detecting deformation of the outer surface of pressure-bearing special equipment, which can be applied to the method described in Embodiment 1. The tool as figure 2 and image 3 Shown includes a housing 1 and a base 2, which are sealed and buckled together. From Figure 4 and Figure 7 It can be seen that the fixing method between the base 2 and the shell 1 is fixed by six screws, four of which are externally penetrating screws 11, and the other two are externally penetrating screws 12. Figure 9 and Figure 10 It can be seen that the housing is in a hexagonal shape, and the six screw connection positions are respectively located at six inner corner positions, and the six screw connection positions located inside the housing are correspondingly provided with six installation holes 10 . Four external penetrating screws 11 are connected from the side of the shell 1 to the side of the base 2, and the handle 7 is fixedly connected at the same ...
