Portable laser convergence gauge device

Abstract

The invention discloses a portable laser convergence gauge device, comprising a laser distance measuring meter, a grab handle, a female connector, a male embedded seat, a nut, a movable cover nut and a movable gasket. The portable laser convergence gauge device is characterized in that a connecting rod of the female connector is inserted into a groove of the grab handle and penetrates through a screw of the grab handle, the nut is screwed, and the female connector and the grab handle are connected together; the female connector and the male embedded seat are in butt joint by a rapid insertion female connector and a rapid insertion male connector, the connecting rod at the grab handle sequentially penetrates through the movable gasket and the movable cover nut, and the laser distance measuring meter is in threaded connection with the grab handle by the connecting rod at the grab handle. The portable laser convergence gauge device has the advantages that the connection is convenient, the structure is simple, the manufacturing cost is low and the positioning is rapid, and can be widely used for measuring the tiny change of the distance between two points along any direction of the surrounding rock periphery of a tunnel, a roadway, a chamber and other engineering.

Description

technical field [0001] The invention belongs to the technical field of rock mass convergence deformation measurement, and more specifically relates to a portable laser convergence meter device, which is suitable for measuring the small change in the distance between two points in any direction around tunnels, roadways, caverns and other engineering surrounding rocks. Background technique [0002] In the frequent measurement of rock mass convergence deformation, the existing technology needs to continuously thread the measuring head when fixing the convergence meter device, and the positioning is performed by tightening the nuts at various places during the measurement process, so the measurement is not only It is time-consuming and labor-intensive, and it also affects the accuracy of the measurement results; in addition, the probe is easily corroded, and it must be cleaned with detergent every time it is measured. During the measurement process of an engineering project, it ...

Problems solved by technology

[0002] In frequent rock mass convergence deformation measurement, the existing technology needs to continuously thread the measuring head when fixing the convergence meter device, and when measuring The process is positioned by tightening the nuts everywhere, so the measurement is not only time-consuming and laborious, but also affects the accuracy of the measurement results; in addition, the probe is easily corroded, and it must be cleaned with detergent every time it is measured, and the probe is corroded. After falling off, it is necessary to drill a hole with an impact drill to re-embed the probe. Sometimes in the measurement process of an engineering project, it is necessary to bury the probe multiple times in the same section, wasting a lot of manpower and financial resources.
