Support device allowing precise adjustment of laser indicating instrument and measurement method

Abstract

The invention provides a support device allowing precise adjustment of a laser indicating instrument and a measurement method. An L-shaped right-angled bracket platform is fixed on a cavity wall, two parallel bolt hole sliding chutes are machined in a horizontal support plate of the L-shaped right-angled bracket platform, a transverse adjustment base is adjustably mounted on the bolt hole sliding chutes through first bolts, fixed clamping plates are mounted on the transverse adjustment base, a longitudinal adjustment support is rotationally mounted on the fixed clamping plates through reinforcing bolts, the laser indicating instrument is mounted in a cylindrical sleeve of the longitudinal adjustment support, and the laser indicating instrument is matched with angle fine-adjustment mechanisms mounted at two ends of the cylindrical sleeve for angle adjustment; a protective cover is adjustably mounted on threaded hole sliding chutes of the horizontal support plate through second bolts. Bilateral quick movement can be realized, transverse precise positioning is facilitated, the angle can be adjusted at will in the vertical direction, a sloped inclined shaft is guided conveniently, and the effect of blast construction on the laser indicating instrument can be effectively avoided.

Description

technical field [0001] The invention relates to a bracket for installing a laser pointing instrument and a measuring method, in particular to a mounting bracket and a method thereof which have a safety protection function in underground cavern excavation and can precisely adjust the pointing of a laser pointing instrument. Background technique [0002] Laser pointing devices are widely used in underground engineering, especially in the excavation of underground mines, large-scale tunnel excavation, urban subway construction, water diversion tunnel construction, and large-scale underground plant excavation. Guide the benchmark and guide the excavation. Especially when encountering long-distance linear tunnels (flat tunnels, inclined shafts or vertical shafts) with small radius sections, the laser pointing device can significantly improve the efficiency of setting out and guiding instead of the total station. However, since the laser pointing device is fixedly installed near ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of unstable installation of the laser pointing instrument, low efficiency of pointing accuracy detection, inconvenient adjustment, and often vulnerable to damage or even damage during the construction process, the present invention designs a new type of laser pointing instrument mounting bracket device and its precise adjustment measurement The method can realize rapid left and right movement, facilitate horizontal and accurate positioning, and can also adjust the angle arbitrarily in the vertical direction, which is convenient for guiding inclined shafts with slopes, and a safety protection device is designed to effectively avoid damage to the laser pointer caused by blasting construction.
