Description

Technical Field

[0001] This utility model relates to the field of posture detection technology for underground equipment in coal mines, specifically, to a laser pointing instrument for underground coal mines. Background Technology

[0002] Laser pointers for underground coal mines are high-precision measurement and positioning devices specifically designed for the underground environment of coal mines. They play a crucial role in mining operations, support operations, improving work efficiency, safety, and project quality, as well as assisting in navigation and data recording. By providing precise positioning and guidance, laser pointers significantly improve the efficiency and safety of underground coal mine operations, meeting the high requirements of coal mining and construction.

[0003] In related technologies, fixing the laser pointer is a cumbersome process, requiring the installation of one anchor bolt each time to fix the laser pointer to the bolt. The effective range of the laser pointer is over 200 meters, and beyond that, the laser needs to be moved promptly. Anchor bolt installation is time-consuming and labor-intensive, and there is a lack of construction precision, requiring constant adjustment of the anchor bolt's bending to regulate the laser's direction and angle. Moreover, anchor bolts can only be used once, wasting support materials and wasting time and labor. Utility Model Content

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following description, with reference to the accompanying drawings, describes a laser pointer 100 for use in underground coal mines according to an embodiment of the present invention.

[0025] like Figure 1 As shown, the underground laser pointer 100 for coal mines according to an embodiment of the present invention includes a mounting plate 2, multiple connectors 3, and a laser pointer 1.

[0026] Mounting plate 2 extends horizontally. Specifically, as shown... Figure 1 As shown, mounting plate 2 is a horizontal plate.

[0027] The upper ends of multiple connectors 3 are all adapted to connect to the steel mesh of the roadway, so that the connectors 3 can be installed on the steel mesh. A mounting plate 2 passes through the multiple connectors 3 and is movable vertically on the mounting plate 2 to adjust its position and angle. The multiple connectors 3 are spaced apart circumferentially along the mounting plate 2. Specifically, as shown... Figure 1 As shown, multiple connectors 3 extend in the vertical direction, and the upper ends of multiple connectors 3 can be connected to the steel mesh in the roadway. The mounting plate 2 is horizontally installed on multiple connectors 3, and the mounting plate 2 can be moved on multiple connectors 3 to adjust the height and installation angle of the mounting plate 2.

[0028] The laser pointer 1 is located below and connected to the mounting plate 2. Specifically, as shown... Figure 1 As shown, the laser pointer 1 is fixedly installed below the mounting plate 2, thereby providing a mounting base for the laser pointer 1.

[0029] The underground laser pointer 100 of this utility model is provided with multiple connectors 3 and a laser pointer 1. The connectors 3 are connected to a steel mesh. Compared with related technologies, there is no need to drive anchor bolts into the roadway, saving time and effort. When the position of the laser pointer 1 needs to be changed, the connectors 3 can be removed from the steel mesh, reducing the processing and manufacturing cost of the underground laser pointer 100. In addition, the mounting plate 2 is movably connected to the connectors 3, and the position and angle of the mounting plate 2 can be adjusted, thereby adjusting the direction and angle of the laser pointer 1. This reduces the construction time during the laser relocation process, ensures rapid roadway excavation, and eliminates the problem of deviation during roadway excavation.

[0030] In some embodiments, the connector 3 includes a bent section 31 and a connecting section 32 connected sequentially in the vertical direction. The bent section 31 is disposed above the connecting section 32 and is suspended from the steel mesh. The mounting plate 2 passes through the connecting section 32 and is movable relative to the connecting section 32 in the vertical direction. Specifically, as shown... Figure 1 As shown, the bent section 31 is a hook, and the connecting section 32 is a vertical rod extending in the vertical direction. The bent section 31 is suspended on the steel mesh so that the connector 3 is suspended on the steel mesh. The mounting plate 2 is inserted on the connecting section 32 and can move in the vertical direction on the connecting section 32, so that the connector 3 is set more reasonably.

[0031] In some embodiments, the mounting plate 2 has a plurality of through holes extending through the mounting plate 2 in the vertical direction, and a plurality of connectors 3 are correspondingly inserted into the plurality of through holes. The connectors 3 are rotatable relative to the through holes in the vertical direction. Specifically, as shown in the figure Figure 1 As shown, multiple through holes penetrate the mounting plate 2 in the vertical direction and are equally spaced around the circumference of the mounting plate 2. The number of multiple through holes is equal to the number of multiple connectors 3, so that a connector 3 is inserted into each through hole and the connector 3 can rotate within the through hole, making the mounting plate 2 more reasonably set.

[0032] In some embodiments, the connecting segment 32 is provided with a first thread, and the through hole is provided with a second thread. The first thread and the second thread engage so that the connecting segment 32 can be installed in the through hole. Specifically, as shown in the figure... Figure 1 As shown, the first thread is an external thread and is located on the outer periphery of the connecting section 32, and the second thread is an internal thread and is located on the inner periphery of the through hole. The connecting section 32 passes through the through hole and is installed in the through hole by the threaded engagement of the first thread and the second thread. The relative position and relative angle of the mounting plate 2 and the connecting piece 3 can be adjusted by rotating the connecting section 32.

[0033] In some embodiments, the plurality of connectors 3 include a first connector 33, a second connector 34, a third connector 35, and a fourth connector 36. The first connector 33, the second connector 34, the third connector 35, and the fourth connector 36 are all equally spaced along the circumference of the mounting plate 2 and are disposed on the mounting plate 2. The upper ends of the first connector 33, the second connector 34, the third connector 35, and the fourth connector 36 are all connected to the steel mesh. Specifically, as shown... Figure 1 As shown, there are four connectors 3: a first connector 33, a second connector 34, a third connector 35, and a fourth connector 36. There are also four through holes. The first connector 33, the second connector 34, the third connector 35, and the fourth connector 36 pass through the through holes and are connected to the steel mesh. Thus, by having the first connector 33, the second connector 34, the third connector 35, and the fourth connector 36 evenly spaced along the circumference of the mounting plate 2, the mounting plate 2 can be provided with multiple points of support. This makes the mounting plate 2 more stable on the steel mesh and ensures the accurate position of the mounting plate 2, avoiding positional deviations caused by single-point support. In addition, multiple-point support can ensure that the load on the mounting plate 2 is evenly distributed, avoiding deformation or damage caused by excessive force at a single point.

[0034] In some embodiments, the mounting plate 2 includes a first plate 21, a second plate 22, a third plate 23, a fourth plate 24, and a fifth plate 25. The first plate 21, second plate 22, third plate 23, and fourth plate 24 are all disposed on the fifth plate 25 and spaced apart circumferentially around the fifth plate 25. A first connector 33, a second connector 34, a third connector 35, and a fourth connector 36 are correspondingly inserted through the first plate 21, second plate 22, third plate 23, and fourth plate 24. Specifically, as shown... Figure 1 As shown, the first plate 21, the second plate 22, the third plate 23, the fourth plate 24 and the fifth plate 25 form a cross plate, and each of the first plate 21, the second plate 22, the third plate 23 and the fourth plate 24 is provided with a through hole, so that the first connector 33, the second connector 34, the third connector 35 and the fourth connector 36 are correspondingly inserted into the first plate 21, the second plate 22, the third plate 23 and the fourth plate 24, thereby making the mounting plate 2 set more reasonably.

[0035] In some embodiments, the laser pointer 100 for underground coal mines further includes a mounting member 4, the upper end of which is disposed on a mounting plate 2, and the laser pointer 1 is mounted on the mounting member 4 and is movable relative to the mounting member 4 in the vertical direction. Specifically, as shown in the figure... Figure 1 As shown, the mounting component 4 is a vertical rod extending in the vertical direction, and the upper end of the mounting component 4 is fixed on the mounting plate 2. The laser pointer 1 is mounted on the mounting component 4, thereby providing a mounting base for the laser pointer 1 through the mounting component 4.

[0036] In some embodiments, the laser pointer 100 for underground coal mines further includes a mounting base 5, which is mounted on a mounting member 4 and movable vertically relative to the mounting member 4. The laser pointer 1 is mounted on the mounting member 4. Specifically, as shown... Figure 1 As shown, the mounting base 5 is mounted on the mounting component 4, and the laser pointer 1 is fixedly mounted on the mounting base 5, thereby providing a mounting foundation for the laser pointer 1.

[0037] In some embodiments, the laser pointer 100 for underground coal mines further includes a first nut 6 and a second nut 7, both of which are threaded onto the mounting member 4 and are threaded into it. A mounting base 5 is located between the first nut 6 and the second nut 7, so that the mounting base 5 is mounted on the mounting member 4 via the first nut 6 and the second nut 7. Specifically, as... Figure 1 As shown, the mounting component 4 is a threaded rod, the first nut 6 and the second nut 7 are inserted through the mounting component 4 and are spaced apart from each other in the vertical direction, and the mounting base 5 is clamped between the first nut 6 and the second nut 7, thereby providing a mounting foundation for the mounting base 5 through the first nut 6 and the second nut 7.

[0038] In some embodiments, the connector 3 further includes a handle located at the lower end of the connector 3. Thus, the connector 3 can be rotated via the handle, changing the relative position of the connector 3 and the mounting member 4, thereby adjusting the height and angle of the mounting plate 2, and consequently adjusting the height and angle of the laser pointer 1 to change the pointing direction of the laser pointer 1.
