Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of center finder, in particular to an adjustable center finder. BACKGROUND

[0002] In the process of installing electromechanical equipment, it is necessary to install multiple fixed parts on the center of the same rotating shaft system. In actual construction, the center point of the reference part is usually determined, and then a mark line is set on the center point. Other parts are adjusted and positioned with this mark line to meet the concentricity requirement and early pass.

[0003] Early pass sets up devices such as piano wire, weight and earphone to cooperate with each other to adjust the center of the circular member installed above the reference part. This method not only needs manual adjustment of the position of the weight multiple times, but also needs to cooperate with the adjustment of the center position of the circular member, which has certain error. At the same time, a long time is needed to determine the center, which affects the progress of the project.

[0004] Although the existing infrared range finder is used to determine the center of the reference part, and then the position of the circular member is adjusted, such as patent application red number: CN202121858786.2, a new center finder is disclosed. In this patent application, the position of the reference part in the electromechanical installation is determined by setting an infrared measurement method. Then, the center line of the cross bar frame, that is, the infrared line, is determined on the position of the cross bar frame, and the position of the circular member is adjusted accordingly.

[0005] However, when the existing electromechanical equipment is installed, it is usually installed by hoisting. After using this method, the center finder on the reference part needs to adjust the position of the circular member before the circular member and the reference part are installed. After the adjustment is completed, the center finder needs to be removed before the installation. During the process of approaching the installation of the circular member and the reference part, the hoisting equipment will shake to a certain extent due to the weight of the circular member, which will cause deviation during the installation process between the circular member and the reference part. Therefore, we propose an adjustable center finder. SUMMARY
