Description

Technical Field

[0001] This utility model belongs to the technical field of circle drawing tools, and in particular relates to a concentric circle tool for replacing the mounting base of a hydraulic cylinder. Background Technology

[0002] In the modification of the hydraulic cylinder mounting base of the tailrace emergency gate, it is crucial to ensure that the new base can be accurately installed in the original concentric circle position, but there is a lack of tools available for drawing concentric circles directly.

[0003] The current process of drawing concentric circles generally requires the use of a measuring tape and marking tools. First, the diameter and position of the original base need to be measured. Then, a straight line is drawn around it using a measuring tape as a reference line. Next, marking tools (such as chalk, pencil, etc.) are used to mark the line with the required radius. Finally, connecting these marked points will draw the concentric circles of the original installation position of the tailrace emergency gate hydraulic cylinder mounting base.

[0004] However, since manual drawing may contain errors, it requires multiple measurements and adjustments to ensure accuracy, which is inefficient.

[0005] Therefore, in order to solve the above problems, it is particularly urgent and important to design a concentric circle tool for replacing the hydraulic cylinder mounting base. Utility Model Content

This tool has a simple structure and is easy to use. It includes an auxiliary plate and an adjustment plate. The auxiliary plate helps the pin to fit snugly against the outer edge of the inner circle, while the adjustment plate helps to draw the outer circle on the basis of the original base. The outer circle is used to position the new base, ensuring accurate positioning. This solves the problem of reinstallation and positioning during the maintenance of hydraulic cylinder mounting bases for tailrace emergency gates, improving the accuracy and efficiency of hydraulic cylinder mounting base replacement.
