Abstract
Description
Technical Field
[0001] This utility model relates to the field of subway canopy production technology, specifically a linear point laser ranging device. Background Technology
[0002] During the production of subway roofs, it is necessary to measure their straightness. The overall length of the roof is more than 20 meters. Currently, the common method is to stretch a horizontal fishing line 20mm away from the roof and then measure the distance between the fishing line and the roof at multiple points. If the distance is 20mm at all points, the straightness of the roof is considered qualified. If the distance is greater or less than 20mm, the straightness has a deviation. However, this method is cumbersome and increases the workload of the staff. It is also not convenient for intuitive measurement. Therefore, we propose a laser ranging device for straight-line points.
