Description

Technical Field

[0001] The utility model relates to the technical field of marking tools, and more specifically to a base three-dimensional marking instrument. Background Art

[0002] As the number of stages of a multi-stage centrifugal pump increases, the size of the motor it carries will also increase. In order to facilitate the installation of the unit, users usually require an integral base. The higher the number of stages, the larger the motor it carries, resulting in the overall base of the large-stage pump unit being overlong and overwide, with a length of more than 4 meters and a width of more than 1.5 meters. There is a height difference between the pump and the motor, and the positions of the four groups of 20 threads or holes of different heights on the overall base can only be determined by manual marking. A height gauge and a steel ruler are generally used on site to determine the position of each hole. The larger the base and the heavier it is, the more difficult it is to mark. Sometimes the base needs to be placed vertically, which not only poses a safety hazard, but also inaccurate marking, resulting in deviations in the drilling position, making it difficult to install the unit, and even requiring secondary drilling after repair welding.

[0003] Therefore, it is necessary to improve the prior art. Utility Model Content
