Description

Technical Field

[0001] This utility model relates to the field of blasting construction technology, and in particular to a blast hole layout and positioning device. Background Technology

[0002] Currently, drill-and-blast construction remains the mainstream construction technique for mine roadway and tunnel engineering. To ensure the quality of the construction roadway and improve its safety and stability, the requirements for drill-and-blast construction are quite stringent. In the drill-and-blast construction process, the accurate positioning of the blast holes is the first hurdle determining the final construction quality. Traditionally, blast hole positioning is primarily done manually using measuring tapes, which is highly prone to errors, ultimately leading to over-excavation or under-excavation of the roadway. In addition, existing technologies also utilize total stations for positioning. Technicians operate the total station, placing laser points one by one on the designed blast hole positions on the roadway wall and marking them with paint or nails. Although the single-point positioning accuracy is extremely high (up to millimeter level), each blast hole requires individual aiming, measurement, and marking, a cumbersome process that demands high operator skills and offers limited overall efficiency improvement.

[0020] The following is in conjunction with the appendix Figure 1 To be continued Figure 4 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0021] A blast hole layout and positioning device includes a light-shielding plate 1, a projection box 3, a light source 5, and a power supply assembly for powering the device. The light-shielding plate 1 provides a light-shielding effect and has holes proportional to the blast hole positions. These holes are through-holes, allowing light to pass through. Several different models of light-shielding plates 1 are prepared according to different tunnels and blast hole construction requirements. The projection box 3 is a box structure with an opening on one side. A snap-fit ​​assembly is provided at the opening of the projection box 3, and the light-shielding plate 1 snaps into the assembly, thus blocking the opening of the projection box 3. The light source 5 is an infrared laser light source, located inside the projection box 3 and facing the opening. The light emitted by the light source 5 passes through the holes in the light-shielding plate 1 and is projected onto the working face. The power supply assembly includes a power supply 6 and a charging port 7 for charging the power supply 6. A switch 4 may also be installed on the projection box 3. The switch 4 is electrically connected to the power supply assembly and the light source 5 to control the on / off state of the light source 5.

[0022] The snap-fit ​​assembly is used for installing the light-shielding plate 1. In one specific embodiment, the snap-fit ​​assembly is a U-shaped slot located at the opening of the projection box 3. The light-shielding plate 1 can slide along the U-shaped slot and be inserted into it. The snap-fit ​​assembly can also be configured as a snap-on mechanism, allowing the light-shielding plate 1 to be installed and removed by opening and closing the snap-on mechanism. To facilitate the removal of the light-shielding plate 1, a handle can be provided on the light-shielding plate 1.

[0023] To achieve better light emission, a light-concentrating cover 2 is also installed inside the projection box 3, and the light source 5 is installed inside the light-concentrating cover 2. The light-concentrating cover 2 has an inclined surface that is conducive to light concentration.

[0024] To facilitate the installation of the device, the projection box 3 is equipped with a mounting component for mounting the device on a general-purpose mining measurement bracket. The mounting component is a nut 8, or other installation methods in the prior art.

[0025] When using this device, firstly, the light-shielding plate 1 is engraved according to the tunnel design, with the tunnel boundary and blast hole positions marked on it. Then, the light-shielding plate 1 is installed at the front end of the projection box 3, and the projection box 3 is fixed to a universal measuring tripod. The height and level of the tripod are roughly adjusted first. Switch 4 is turned on, the light source 5 illuminates, and the projection of the blast hole points onto the working face is observed. The tripod is moved back and forth as needed, and then the height and level are finely adjusted to ensure that the projection of the tunnel design boundary is exactly at the actual working face location, thus achieving the positioning of the designed blast holes.
