Description

Technical Field

[0001] This invention relates to the field of underground coal mine measurement technology, and in particular to a coal mine underground measurement centering and windproof device. Background Technology

[0002] When used for underground coal mine surveying, the centering and windproof device ensures accurate instrument positioning and reduces deviations through precise centering. Simultaneously, its windproof structure resists interference from underground airflow, preventing instrument swaying, ensuring stable and reliable measurement data, and improving measurement accuracy and efficiency. This provides a reliable measurement benchmark for underground tunnel excavation and engineering construction, reducing measurement errors caused by environmental factors.

[0003] Existing underground coal mine centering and windproof devices cannot perform rapid measurement operations. They require repeated manual adjustments of the centering components and windproof structure, which is time-consuming and labor-intensive. Moreover, the devices are mostly fixed in structure, and need to be disassembled and reassembled to adapt to different measuring instruments, making the operation cumbersome. At the same time, the humid and dusty underground environment can easily cause the components to jam, further prolonging the adjustment time, affecting the measurement efficiency, and increasing the workload of personnel and the duration of underground operations.

[0004] Therefore, this application provides a coal mine underground measurement centering and windproof device to meet the requirements. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a coal mine underground measurement centering and windproof device.

[0008] Furthermore, a second guide groove is provided at the bottom of the fixed base near the guide shaft, and the sliding rod is slidably disposed inside the second guide groove.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the second guide groove at the bottom of the fixed seat cooperates with the sliding rod, and the sliding rod slides along the groove to allow the canvas to be unfolded or retracted, realizing flexible switching of windproof function.

[0010] Furthermore, a support plate is provided at the bottom of the rotating ring, a rotating shaft is provided at the bottom of the support plate, a positioning seat is rotatably provided at the bottom of the rotating shaft, and an observation camera is provided at the top of the rotating ring.

The first rotating rod on the fixed block at its end can rotate and, in cooperation with the guide block, realize multi-angle adjustment, providing stable support and fixation for the equipment from the bottom and the perimeter, adapting to the complex ground environment in coal mines.

[0014] Furthermore, a first guide groove is provided on the first rotating rod, a positioning block is provided at the other end of the first rotating rod, and a guide block is provided on the top of the base plate. The first rotating rod is slidably connected to the guide block through the first guide groove.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the first guide groove on the first rotating rod is slidably connected to the top guide block of the base plate, allowing it to rotate and slide flexibly. During rotation, the positioning block at the other end cooperates with the fixing block to firmly support the equipment, adapt to different terrains, and enhance the stability of the device in underground coal mines.

[0016] Furthermore, the top of the lifting plate is connected to the support platform, and the outer side of the base plate away from the support assembly is provided with a dustproof outer plate.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1-5 As shown, the present invention provides a technical solution: a coal mine underground measurement and alignment windproof device, including a base plate 1 and a support platform 4 placed on top of the base plate 1, and further including:

[0032] The measuring component 5 includes a rotating ring 54 mounted on the top of the support platform 4. A fixed seat 55 is mounted on the outer side of the rotating ring 54. A second rotating rod 56 is mounted on one side of each fixed seat 55, and a measuring piece 57 is mounted on the outer side of each second rotating rod 56. A guide shaft 58 is mounted on the other side of the fixed seat 55 away from the second rotating rod 56. A canvas 59 is mounted at the bottom of the guide shaft 58, and a sliding rod 510 is mounted at the bottom of the canvas 59. When the measuring component 5 is in operation, the rotating ring 54 can rotate on the top of the support platform 4, causing the outer fixed seats 55 to adjust their orientation. The second rotating rod 56 supports the measuring pieces 57 for alignment in underground coal mine measurements. The guide shaft 58 guides the canvas 59 to unfold or retract. The sliding rod 510 slides along the second guide groove 511 of the fixed seat 55. The canvas 59 can block airflow and improve measurement accuracy. All components work together to ensure stable and accurate underground measurement operations.

[0033] Furthermore, such as Figures 1-5 As shown: The bottom of the fixed base 55 near the guide shaft 58 has a second guide groove 511. The sliding rod 510 is slidably disposed inside the second guide groove 511. The second guide groove 511 at the bottom of the fixed base 55 cooperates with the sliding rod 510. The sliding rod 510 slides along the groove, so that the canvas 59 can be unfolded or folded up, realizing flexible switching of windproof function.

[0034] The above schemes also have the problem of manipulating observations, such as... Figure 5 As shown: In this scheme, a support plate 53 is provided at the bottom of the rotating ring 54, a rotating shaft 52 is provided at the bottom of the support plate 53, a positioning seat 51 is rotatably provided at the bottom of the rotating shaft 52, and an observation camera 512 is provided at the top of the rotating ring 54. The rotating ring 54 can rotate flexibly by relying on the cooperation of the bottom support plate 53, the rotating shaft 52 and the positioning seat 51. The observation camera 512 at the top rotates with the rotating ring 54 and can collect images of the underground measurement area of ​​the coal mine from multiple angles, which is convenient for operators to remotely observe and accurately measure.

[0035] The above solutions still have the problem of adjusting the height of the fixed equipment, such as... Figure 4As shown: In this scheme, a support assembly 3 is provided inside the base plate 1. The support assembly 3 includes a telescopic column 31 set on the top of the base plate 1, a baffle plate 32 set on the top of the telescopic column 31, a damping spring 33 sleeved on the baffle plate 32, a lifting plate 34 set on the top of the damping spring 33, a telescopic plate 35 set on the outside of the lifting plate 34, and a fixing block 36 set on the other side of the telescopic plate 35. A first rotating rod 37 is rotatably set on the fixing block 36. The telescopic column 31 is set on the top of the base plate 1 and can be telescopically adjusted in height, driving the baffle plate 32 to rise and fall. The damping spring 33 is sleeved on the baffle plate 32 to buffer external vibration and impact and improve stability. The lifting plate 34 is connected to the top of the telescopic column 31 and moves up and down under the drive of the telescopic column 31 and the action of the damping spring 33. The telescopic plate 35 moves and extends with the lifting plate 34. The first rotating rod 37 on the fixing block 36 at its end can rotate. By cooperating with the guide block 38, multi-angle adjustment can be realized, providing stable support and fixation for the equipment from the bottom and the periphery, adapting to the complex ground environment of the coal mine.

[0036] Working principle: such as Figures 1-5 As shown, the rotating ring 54 of the measuring component 5, relying on the bottom support plate 53, the rotating shaft 52, and the positioning seat 51, rotates flexibly on the top of the support platform 4, driving the outer fixed seat 55 to adjust its orientation, so that the measuring piece 57 supported by the second rotating rod 56 can be aligned for underground coal mine measurements. At the same time, the second guide groove 511 at the bottom of the fixed seat 55 cooperates with the sliding rod 510. By sliding the sliding rod 510 along the groove, the canvas 59 is guided to unfold or retract, or rotate around the guide shaft 58, realizing flexible switching of windproof function and improving measurement accuracy. The top observation camera 512 rotates with the rotating ring 54 and can collect images from multiple angles to assist in remote observation. In the support component 3, the telescopic column 31 is set on the top of the base plate 1. The height adjustment of the telescopic adjustment causes the baffle plate 32 to rise and fall. The damping spring 33 fitted on the baffle plate 32 buffers the vibration. The lifting plate 34 is connected to the top of the telescopic column 31 and moves under its drive and the action of the damping spring 33, causing the telescopic plate 35 to extend and retract. The first rotating rod 37 on the fixed block 36 achieves multi-angle adjustment by cooperating with the guide block 38. The first guide groove 310 on the first rotating rod 37 is slidably connected to the guide block 38, and cooperates with the positioning block 39 at the other end to stabilize the support equipment. In addition, the top of the lifting plate 34 is connected to the support platform 4 to realize its lifting and lowering. The dustproof outer plate 2 on the outside of the bottom plate 1 blocks dust. All components work together to achieve stable support, accurate measurement and reliable protection of the device in the complex environment downhole.
