Description

Technical Field

[0001] This utility model relates to the field of mining measurement prisms and scanning targets, specifically a device for combining a metal mine measurement prism and a scanning target. Background Technology

[0002] Currently, in surface and underground surveying and 3D laser scanning operations in metal mines, to ensure the accuracy of measurement and 3D laser scanning, it is generally necessary to center, level, and erect measuring prisms and set up 3D laser scanning targets at the measurement control points. However, factors such as trackless equipment and personnel at the mine surface and underground work sites seriously interfere with the measurement operation, thereby affecting the efficiency of centering, leveling, erecting measuring prisms, and setting up 3D laser scanning targets at the measurement control points on the mine surface and underground roadway floor, and may even affect the accuracy of surface and underground measurement and scanning.

[0003] Therefore, it is necessary to design a device that combines a metal mine measuring prism with a scanning target to solve the above problems, minimize the time required to set up the measuring prism, and achieve the goal of directly and quickly setting up the measuring prism and deploying the three-dimensional laser scanning target at the measuring control points on the mine surface and underground roadway floor, thus completing the use of the measuring prism and scanning target on the mine surface and underground. Utility Model Content

[0004] The purpose of this invention is to provide a device for combining a metal mine measuring prism with a scanning target, so as to solve the problems mentioned in the background art.

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

[0006] A metal mine measuring prism and scanning target connection device includes a fixed bracket. The top of the fixed bracket is fixedly installed with a scanning target. The front and rear sides of the fixed bracket are symmetrically arranged with clamps. The connection between the two clamps is provided with symmetrically distributed docking fastening plates. The fastening is completed by fully docking the docking fastening plates on the same side of the clamps and then using fastening screws to pass through the docking fastening plates.

[0007] As a further improvement of this utility model, the clamp plate located at the front has a cavity for mounting the measuring prism.

[0008] As a further improvement of this utility model: the front clamp plate is provided with two fastening knobs at different positions, one on the front of the clamp plate and the other on the upper side of the clamp plate. The fastening knob on the front of the clamp plate can penetrate through the front clamp plate and contact the fixed bracket, while the fastening knob on the upper side of the clamp plate can pass through the cavity and contact the measuring prism.

[0009] As a further improvement of this utility model: the clamping plate has mounting grooves on both sides, and the fixed bracket is designed as a U-shaped frame, with the two side frames of the fixed bracket located in the mounting grooves during installation.

[0010] As a further improvement of this utility model, a support rod is fixedly installed below the fixed bracket.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This device facilitates the fixing and erection of measuring prisms and scanning targets on the mine surface and underground. It effectively avoids the interference of centering and leveling the measuring prisms and setting up the 3D laser scanning targets at control points on the mine surface and underground roadway floor. It allows for more convenient and safer disassembly, installation, and use of the measuring prisms and scanning targets, and also facilitates their fixing. This invention has a compact structure, simple principle, is easy to manufacture, low cost, easy operation, and good performance, making it particularly valuable for the promotion of underground mine surveying.

[0017] Please see Figure 1 This is a schematic diagram of the overall structure of a metal mine surveying prism and scanning target connection device. The device includes a fixed bracket 2, on which a scanning target 1 is fixedly mounted. Clamping plates 3 are symmetrically arranged on the front and rear sides of the fixed bracket 2. Symmetrically distributed mating fastening plates 7 are provided at the connection points of the two clamping plates 3. During installation, the mating fastening plates 7 on the same side of the clamping plates 3 are fully aligned, and then fastening screws 4 are passed through the mating fastening plates 7 to complete the fastening. The fixed bracket 2 can be placed between the two clamping plates 3 to achieve fixation.

[0018] like Figure 2As shown, a cavity for mounting the measuring prism 5 is provided on the front clamping plate 3. Two fastening knobs 8 are located at different positions on the front clamping plate 3: one on the front and the other on the upper side. The front fastening knob 8 passes through the front clamping plate 3 and contacts the fixing bracket 2, allowing adjustment of the tightness between the clamping plate 3 and the fixing bracket 2 during tightening. The upper fastening knob 8 passes through the cavity and contacts the measuring prism 5, allowing adjustment of the tightness of the measuring prism 5 within the cavity. In this embodiment, this device can be used to fix measuring prisms 5 of different specifications and scanning targets 1.

[0019] like Figure 3 As shown, mounting slots are provided on both sides of the clamping plate 3, and the fixed bracket 2 is designed with a U-shaped frame. By placing the two side frames of the fixed bracket 2 in the mounting slots, the stability of the fixed bracket 2 when installed between the clamping plates 3 can be achieved.

[0020] In addition, a support rod 6 is fixedly installed below the fixed bracket 2. The support rod 6 allows the device to be fixed on the measurement control point set on the mine surface or underground roadway to complete the centering, leveling and erection of the measuring prism 5 and the scanning target 1, so as to better complete the use of the measuring prism 5 and the scanning target 1 on the mine surface and underground.
