Description

Technical Field

[0001] The utility model relates to the technical field of steel truss manufacturing, in particular to a measuring device for in-field manufacturing of road-rail dual-purpose steel truss. Background Art

[0002] Steel trusses are a commonly used bridge structural material, made of welded or riveted steel plates, and play a supporting and bearing role in bridge engineering. Steel trusses have the advantages of high structural strength, large load-bearing capacity, and high design freedom. They can adapt to different spans and load requirements and are widely used in various bridge projects. Due to their corrosion resistance and easy maintenance, steel trusses are widely used in bridge engineering. When manufacturing dual-use steel trusses for road and rail in the field, laser rangefinders are often used to quickly and accurately measure the length, height and other dimensions of steel trusses.

[0003] The screen of a traditional laser rangefinder is in direct contact with the outside world and lacks protective devices. The working environment of the laser rangefinder is relatively complex and the screen is relatively easy to be damaged, which in turn increases the cost of use. Utility Model Content
