Description

This invention relates to measuring equipment and lifting mechanisms, and more particularly to lifting mechanisms and equipment for measuring the flatness of raised floors. Raised floors are a flooring system widely used in semiconductor factories, offices, computer rooms, and other similar facilities. They essentially consist of a support frame and multiple height-adjustable floor slabs. These slabs are raised from the ground to create space for electrical wiring, cables, pipes, and other equipment, and can also improve ventilation and heat dissipation. To ensure the entire floor surface is flat, it is necessary to inspect the flatness of the raised floor to avoid errors and structural problems after installation. Methods for measuring the flatness of a raised floor typically involve visually inspecting the level of the horizontal line, requiring comparison of two or more points during operation. Another method involves using a ruler (straight ruler) or measuring rod, placing it on the raised floor to inspect its flatness. This involves placing the ruler at different points on the floor and checking whether it touches the ground; any uneven areas indicate a problem with flatness. However, these methods often consume manpower and rely on the experience and judgment of the on-site process manager, thus reducing overall process efficiency.
