[0002] During the installation of centrifugal compressors, the installation of locating pins is a necessary process before the compressor no-load test. Currently, there is a lack of special tools to assist in the installation of centrifugal compressor locating pins. The traditional construction method is to directly attach the magnetic drill to the compressor leg, or to make a small magnetic drill support frame at the construction site.

[0003] When the magnetic drill is directly attached to the compressor leg for drilling, the adjustment space is very small when the magnetic drill is adjusted for drilling position due to the limited area of ​​the compressor leg. The magnetic drill support frame made at the construction site is prone to vibration during the drilling process, and the magnetic drill support frame will shake under the influence of the upward force. At the same time, when the placement of the magnetic drill support frame conflicts with the lubricating oil pipeline on the compressor base, it is difficult to find a suitable placement position. The above problems not only result in low construction efficiency and low drilling accuracy, but also have a certain impact on the operating safety of construction personnel. Utility Model Content
