[0002] At present, in the underground measurement and 3D laser scanning operations of metal mines, the measurement control points are basically calibrated at the roof of the underground tunnel. In order to ensure the accuracy of underground measurement and 3D laser scanning in mines, it is generally necessary to set up measurement prisms and arrange 3D laser scanning targets under the measurement control points of the underground tunnel roof. However, the wind force and wind speed in the underground mine tunnel seriously affect the stability of the centering hammer ball under the hanging point, which in turn affects the work efficiency of the centering and leveling installation of measurement prisms and the arrangement of 3D laser scanning targets under the measurement control points of the underground tunnel roof.

[0003] Therefore, it is necessary to design a combined suspension device for underground measuring prisms and scanning targets in metal mines to solve the above problems, avoid setting up measuring prisms, and achieve the purpose of directly and expressly suspending measuring prisms and scanning targets under the measurement control points of the underground tunnel roof, thereby completing the use of measuring prisms and scanning targets in mines.

[0009] As a further solution of the present invention: wherein, the fixing bracket includes two side panels, and grooves corresponding to the side panels are respectively provided on both sides of the splint. During installation, the two side panels of the fixing bracket are divided and located in the grooves of the splint.

[0010] As a further solution of the present invention: wherein, docking fastening plates are symmetrically installed on both sides of the splint. After the splints are brought close together, the docking fastening plates fit together, and the two splints are fixed by inserting fastening screws into the mounting holes on the docking fastening plates.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This device facilitates the fixation and suspension of measuring prisms and scanning targets in underground mines, and can effectively avoid the influence of the centering and leveling installation of measuring prisms and the layout of three-dimensional laser scanning targets under the measurement control points of the underground tunnel roof.

[0016] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be considered as illustrative in nature and not restrictive.

[0017] See also Figures 1 to 3: A combined suspension device for measuring prisms and scanning targets in underground metal mines, the device includes a fixed bracket 2, the fixed bracket 2 is made of a stainless steel plate with a thickness of 2 mm, a rope suspension ring 1 is installed on the top of the fixed bracket 2, a scanning target 9 is installed on the bottom of the fixed bracket 2, and clamps 3 are fixedly installed on the front and back sides of the fixed bracket 2. The two clamps 3 are brought close to each other to clamp the measuring prism 5 on the fixed bracket 2, and docking fastening plates 7 are installed on the left and right sides of the clamps 3. After the two clamps 3 are brought close to each other, the docking fastening plates 7 are fitted together, and the two clamps 3 are fixed by inserting the fastening screws 4 into the mounting holes on the docking fastening plates 7.

[0018] Furthermore, tightening knobs 8 are mounted on the front and upper sides of the clamping plate 3. The clamping plate 3 defines a cavity for mounting the measuring prism 5. The tightening knob 8 on the upper side of the clamping plate 3 extends downward through the cavity and contacts the measuring prism 5. The tightening knob 8 on the upper side of the clamping plate 3 is used to adjust the tightness between the clamping plate 3 and the measuring prism 5. The tightening knob 8 on the front side of the clamping plate 3 extends through the clamping plate 3 and contacts the fixed bracket 2. The tightening knob 8 on the front side of the clamping plate 3 is used to adjust the tightness between the clamping plate 3 and the fixed bracket 2. This achieves a stable mounting effect for the measuring prism 5, making the device adaptable to the suspension and fixation of measuring prisms 5 and scanning targets 9 of different specifications. Using a rope 6 to suspend the measuring prism 5 and scanning target 9 below a measurement control point on the roof of an underground mine tunnel effectively facilitates the use of the measuring prism 5 and scanning target 9 in the mine.

[0019] The fixing bracket 2 includes two side panels, and grooves corresponding to the side panels are provided on both sides of the clamping plate 3. When installed, the two side panels of the fixing bracket 2 are respectively located in the grooves of the clamping plate 3. This improves the installation stability between the fixing bracket 2 and the clamping plate 3.

[0020] Working principle: When in use, the two clamps 3 installed on the outside of the fixed bracket 2 are brought together to clamp the measuring prism 5 on the fixed bracket 2. The docking fastening plates 7 are installed on the left and right sides of the clamp 3. After the docking fastening plates 7 are brought close to each other and fit together, the measuring prism 5 can be fixed to the fixed bracket 2 by fastening the screws 4 through the mounting holes. The tightening knob 8 on the front of the clamp 3 is adjusted to control the tightness of the clamp 3 and the fixed bracket 2. The tightening knob 8 on the upper side of the clamp 3 is adjusted to control the tightness of the clamp 3 and the measuring prism 5, so that the device can adapt to the suspension and fixation of measuring prisms 5 and scanning targets 9 of different specifications. The measuring prism 5 and the scanning target 9 are suspended under the measurement control point of the roof of the underground mine tunnel with a rope 6, and the use of the measuring prism 5 and the scanning target 9 in the mine is started.
