Description

Technical Field

[0001] The utility model mainly relates to the technical field of laser line marking instruments, in particular to a laser line marking instrument for excavation construction. Background Art

[0002] Laser line marking instruments have a wide range of uses, including but not limited to decoration, building construction, and excavation construction. Currently, laser line marking instruments have become a very mature marking tool that can effectively assist construction work. Especially in the field of excavation construction, cutting and forming is one of the main conditions for measuring the quality of comprehensive tunnel construction. In the early stage, in order to control the tunnel forming, the method of drawing contour lines with paint has been used. This method has many problems in actual application. First, due to the uneven coal (rock) wall, it is difficult for paint to adhere. Second, due to the dust generated during the cutting process, the contour lines that are barely drawn are easily covered by dust and cannot play their due role. Third, due to the angle of the driver's line of sight on the non-operating side, once the cutting head of the comprehensive tunneling machine touches the contour line, there is no reference object to choose from, resulting in excessive fatness on the right side. With the assistance of a laser line marking instrument, work efficiency can be significantly improved.

[0003] The application of laser line marking in excavation construction differs from that in building construction or renovation. While the use of laser line marking instruments in building construction and renovation is relatively comfortable, requiring only a flat surface for placement, excavation marking is more challenging. Finding a flat, stable location within an excavation tunnel can be challenging, making it difficult to stably position the laser line marking. Consequently, existing laser line marking products are not well suited for excavation construction. Utility Model Content
