Description

Technical Field

[0001] This invention pertains to measuring devices, specifically relating to an auxiliary measuring device for mounting and positioning a cylinder adjustment ring bracket. Background Technology

[0002] In the field of nuclear power plant construction, core shell components are often large in size. At the same time, due to the safety requirements of nuclear power plants, the installation precision of these shell components is also required to be high.

[0003] In the CAP1000 stack type, the electrical support drawings for the CV shell adjusting ring provide the cable tray center coordinates for positioning. However, during actual installation, it was found that most of the coordinate points provided in the drawings were in suspended positions, making measurement and positioning difficult. Furthermore, due to angle issues with some supports, relying solely on the cable tray center coordinates for positioning could not accurately pinpoint the anchoring points of the electrical supports on the SPL steel structure. Given the stringent requirements of upstream technical documents regarding measurement procedures and accuracy, and to ensure the quality of the measurement work, the anchoring points on the SPL steel structure must be accurately determined on-site. Traditional measurement methods are no longer sufficient to meet design requirements, exhibiting low measurement efficiency and posing significant quality risks.

[0004] Therefore, a new auxiliary measuring device for installing the cylinder adjustment ring bracket is needed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing an auxiliary measuring device for the installation and positioning of a cylinder adjustment ring bracket.

[0006] This invention is achieved as follows: a cylindrical adjusting ring bracket installation and positioning auxiliary measuring device, wherein parallel angle steels are fixedly connected by screws, and a steel pipe is installed at the center of one of the angle steels.

[0007] As described above, in the auxiliary measuring device for installing a cylinder adjusting ring bracket, the two parallel angle steels are arranged back to back, that is, the angle steels are arranged in an "L" shape back to back.

[0008] As described above, in the auxiliary measuring device for installing a cylinder adjusting ring bracket, the angle steel connected to the steel pipe is the front angle steel, and the other angle steel is the rear angle steel.

[0009] As described above, in the auxiliary measuring device for installing a cylinder adjusting ring bracket, the two screws are identical. With the direction of the steel pipe as the top, the one located on the left is the left connecting screw, and the one located on the right is the right connecting screw.

[0010] As described above, in the auxiliary measuring device for installing a cylinder adjusting ring bracket, the screw and the angle steel are connected by threads, and the steel pipe and the angle steel are welded together.

[0011] As described above, the auxiliary measuring device for installing the cylinder adjusting ring bracket is provided, wherein the angle steel is a 40×40 equilateral angle steel.

[0012] As described above, an auxiliary measuring device for mounting a cylinder adjusting ring bracket is provided, wherein the screw is an 8mm screw.

[0013] As described above, an auxiliary measuring device for installing a cylinder adjusting ring bracket is provided, wherein the steel pipe is a 500mm square tube.

[0014] The significant effects of this new invention are: (1) reducing the intensity of construction work; (2) simple design and production with low cost; (3) highly targeted and easy to operate; and (4) reusable. Attached Figure Description

[0017] An auxiliary measuring device for installing a cylindrical adjusting ring bracket mainly consists of 40mm angle steel, an 8mm screw with a corresponding nut, and a 40mm*40mm*1.5mm square tube. Two 80mm long 40mm angle steels are used, and two 8mm diameter holes are drilled at 25mm on both sides of each angle steel. The center of the second 40mm angle steel is welded to the 500mm square tube.

[0018] The structure and usage of the device in this application are roughly as follows:

[0019] The measuring device consists of a 40° angle steel welded to a square tube at its center, with the two angle steels connected by screws for auxiliary measurement. This device is fixed to the SPL steel structure column, and the center point of the column is measured using a right-angle ruler. The Y-axis coordinate of this center point is then determined. The center point of the square tube coincides with the center point of the SPL steel structure. A measuring mirror is placed on the square tube and moved along its centerline to measure the x-coordinate. After measuring the (X, Y) axis coordinates, they are compared with the coordinates on the drawing. If they match, the obtained coordinates are the actual coordinates of the support structure.

[0020] The cost-benefit analysis of the device applied for is as follows:
