Description

Technical Field

[0001] The utility model belongs to the technical field of laser installation, and in particular relates to a side wall bracket for a multi-beam visible laser. Background Art

[0002] Long tunnel excavations are often the defining project of the entire line, often requiring long construction periods and tight deadlines. Tunnel construction surveying requires swift action and accurate data to ensure timely control of tunnel excavation direction and real-time visibility of tunnel cross-section clearances. However, unfavorable measurement conditions such as limited space, low light levels, and poor weather conditions during tunnel construction present significant challenges for surveyors.

[0003] During tunnel blasting construction, the traditional method for locating blastholes on the face is to use a total station combined with manual dot marking. The total station is used to lay out several key peripheral hole positions, and on-site drillers and blasters arrange slot holes, collapse holes, and peripheral holes according to their previous experience. In production practice, each cycle of layout takes about 30 minutes, which is a long time. The randomness of the hole layout leads to discrete particle sizes of slag after on-site blasting, making it difficult to directly reuse them. The inaccurate spacing and position of the peripheral holes lead to obvious over-excavation and under-excavation in the blasting. At the same time, there are also safety risks such as falling from height and being hit by objects.

[0004] As the concept of safe, environmentally friendly, rapid, mechanized, and automated tunnel construction becomes increasingly popular in my country, coupled with rising labor costs, higher requirements are being placed on the mechanization and automation of tunnel construction. To address the challenges of poor accuracy and low efficiency in blasthole placement on the tunnel face, a multi-beam visible laser is used to project the tunnel contour and associated blasthole locations onto the tunnel excavation face. This enables rapid and high-precision measurement and positioning of the tunnel excavation contour and blastholes.

[0005] When using a multi-beam visible laser for tunnel excavation contour surveying, it is sometimes necessary to fix the multi-beam visible laser on the side wall. It is necessary to provide the multi-beam visible laser with a stable bracket that can be fine-tuned in horizontal and vertical angles. Utility Model Content
