Description

Technical Field

[0001] This utility model relates to the field of metal mine measurement and scanning technology, specifically an auxiliary disk for collecting control points for metal mine measurement. Background Technology

[0002] Currently, in metal mine surveying and 3D laser scanning operations, measurement control points are basically marked on the roof and sides of underground roadways. To ensure the accuracy of measurement and 3D laser scanning, handheld 3D laser scanners are needed to collect the 3D coordinates of the measurement control points. However, it is extremely inconvenient to set up scanning targets in underground roadways of metal mines, and a total station is also needed to assign 3D coordinates to the 3D laser scanning targets. This greatly affects the efficiency of 3D laser scanning in metal mines.

[0003] Therefore, it is necessary to design an auxiliary disk for handheld 3D laser scanning technology to collect measurement control points in metal mines to solve the above problems, avoid the need to set up 3D laser scanning targets, and realize the purpose of directly and quickly collecting the 3D coordinates of measurement control points by handheld 3D laser scanners, thus completing the use of handheld 3D laser scanners in metal mines. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary panel for collecting measurement control points in metal mines, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An auxiliary disk for collecting measurement control points in a metal mine includes a base. The upper part of the base has measurement control point holes, and the lower part of the base has fixing holes and fixing bolts. The base includes a triangular portion and a square portion located below the triangular portion. The measurement control points are located in the triangular portion of the base, and the fixing holes and fixing bolts are located in the square portion of the base.

[0007] The fixing bolt includes a chassis, with a screw inserted at the center of the chassis and a pull ring above it; the pull ring is semi-circular, and its two ends are rotatably connected to the two sides of the chassis.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The device aligns the handle of the handheld 3D laser scanner with the auxiliary disk, and uses fixing bolts to fix the handle of the handheld 3D laser scanner through the fixing holes on the lower part of the base. The measurement control point holes on the upper part of the base are aligned with the measurement control points of the metal mine, so that the handheld 3D laser scanner can directly, quickly and accurately collect the 3D coordinate data of the measurement control points of the metal mine.

[0014] Please see Figure 1 and Figure 2 This is a schematic diagram of the overall structure of the device. The device includes a base 1, with a measurement control point hole 3 on the upper part of the base 1, and a fixing hole 2 and a fixing bolt 4 on the lower part of the base 1. The base 1 includes a triangular portion and a square portion located below the triangular portion. The measurement control point hole 3 is located in the triangular portion of the base 1, and the fixing hole 2 and the fixing bolt 4 are located in the square portion of the base 1. The base 1 is 8cm wide and 15cm high.

[0015] The fixing bolt 4 includes a base plate 4a, with a screw 4b inserted at the center of the base plate 4a and a pull ring 4c above it. The pull ring 4c is semi-circular and its two ends are rotatably connected to the two sides of the base plate 4a.

[0016] In this embodiment, by setting measurement control point holes 3, a handheld 3D laser scanner is used to collect the 3D left side data of the measurement control points in the metal mine. The fixing holes 2 set below the base 1 can be used to connect the handle of the handheld 3D laser scanner to the auxiliary disk. The auxiliary disk is fixed by fixing bolts 4 through the fixing holes 2 to ensure its stability. This can adapt to the acquisition of 3D left side data of measurement control points of different types of metal frames, greatly improve the accuracy of acquiring measurement control points in the metal mine, and realize the rapid acquisition of 3D coordinate data of measurement control points in the metal mine by the handheld 3D laser scanner.

[0017] Working principle: In actual use, the handle of the handheld 3D laser scanner is aligned with the auxiliary disk, and the fixing bolt 4 is fixed to the handle of the handheld 3D laser scanner through the fixing hole 2 on the lower part of the base 1. The measurement control point hole 3 on the upper part of the base 1 is aligned with the metal mine measurement control point, so that the handheld 3D laser scanner can directly, quickly and accurately collect the 3D coordinate data of the metal mine measurement control point.
