Description

Technical Field

[0001] This utility model belongs to the field of coal mine rockburst prevention and control technology, and more specifically, it relates to a coal mine rockburst prevention and control monitoring and early warning device. Background Technology

[0002] Rockburst refers to the violent fluctuations in underground pressure that may occur during coal mining due to the release of stress in the coal seam and surrounding rock strata, which can lead to ground subsidence, damage to mine equipment, and even casualties. Coal mine rockburst prevention and monitoring early warning devices are equipment used to detect and prevent underground rockbursts in coal mines.

[0003] Currently, some coal mine rockburst prevention and monitoring early warning devices are installed in designated locations inside the mine. This makes it inconvenient to adjust the sensor position according to the warning location, resulting in frequent installation of frames by workers to support the sensors, which is inefficient.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a coal mine rockburst prevention and monitoring early warning device in order to achieve a more practical value. Utility Model Content

A first mounting groove extends through one side of the connecting seat and connects to the pair of first sliding grooves. A first driving component is installed in each pair of first sliding grooves. A second driving component is installed inside one of the pair of first mounting seats.

[0007] Furthermore, the first drive assembly includes a pair of threaded rods, which are rotatably mounted in a pair of first slides via bearing seats, and the pair of threaded rods pass through the upper and lower ends of a pair of first sliders and are threadedly connected to the pair of first sliders.

[0008] Furthermore, a pair of synchronous pulleys are mounted at the bottom end of the pair of threaded rods, and the pair of synchronous pulleys are connected by a transmission belt.

[0009] Furthermore, a first motor is mounted at the bottom end of one of the pair of first grooves, and the output end of the first motor is connected to the threaded rod via a coupling.

[0010] Furthermore, the second drive assembly includes a second mounting slot, which is formed inside one of the pair of first mounting seats. A worm gear is rotatably mounted in the second mounting slot via a bearing seat, and the worm gear is connected to the rotating shaft. A worm is rotatably mounted at the bottom end of the second mounting slot via a bearing seat, and the worm is meshed with the worm gear.

[0011] Furthermore, a second motor is installed on one side of the bottom end of the second mounting slot, and the output end of the second motor is connected to the worm gear drive via a coupling.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 3 As shown:

[0025] This utility model provides a coal mine rockburst prevention and monitoring early warning device, including a base 1 and a sensing mechanism 2. The sensing mechanism 2 includes a ground pressure sensor, a displacement sensor, a vibration sensor, etc., for real-time detection of the internal conditions of the mine. A pair of supports 3 are installed at the top of the base 1. Each pair of supports 3 has a first sliding groove 4 on its opposite side. A first slider 5 is slidably installed in each pair of first sliding grooves 4. The cross-section of the first sliding groove 4 and the first slider 5 is square, so that the first sliding groove 4 can limit the movement of the first slider 5. A first mounting seat 6 is installed on each pair of first sliders 5 on its opposite side. A pair of first mounting seats 6 each have a pair of rotating shafts 7 rotatably mounted on opposite sides via bearing seats. The sensing mechanism 2 is mounted between the pair of rotating shafts 7. The angle of the sensing mechanism 2 can be adjusted by rotating the pair of rotating shafts 7. A pair of brackets 3 each have a connecting seat 8 mounted on the bottom of opposite sides. A first mounting groove 9 is provided through one side of the connecting seat 8 and is connected to a pair of first sliding grooves 4. A first driving assembly is installed in the pair of first sliding grooves 4 to drive the first slider 5 to move. A second driving assembly is installed inside one of the pair of first mounting seats 6 to drive the sensing mechanism 2 to rotate.

[0026] The first drive assembly includes a pair of threaded rods 10, which are rotatably mounted in a pair of first slide grooves 4 via bearing seats, and the pair of threaded rods 10 pass through the upper and lower ends of a pair of first sliders 5 and are threadedly connected to the pair of first sliders 5.

[0027] Among them, a pair of synchronous pulleys 11 are installed at the bottom of a pair of threaded rods 10, and the pair of synchronous pulleys 11 are connected by a transmission belt. The synchronous pulleys 11 are set at a position parallel to the first mounting groove 9, so that the transmission belt can pass through the first mounting groove 9 to connect the two synchronous pulleys 11 together.

[0028] In this pair of first slides 4, a first motor 12 is installed at the bottom end of one of them, and the output end of the first motor 12 is connected to the threaded rod 10 via a coupling.

[0029] The first motor 12 drives a threaded rod 10 to rotate. Under the transmission action of a pair of synchronous pulleys 11, the pair of threaded rods 10 rotate synchronously. Then, under the limiting action of the first slide groove 4, the pair of first sliders 5 move up and down simultaneously.

[0030] The second drive assembly includes a second mounting groove 13, which is located inside one of a pair of first mounting seats 6. A worm gear 14 is rotatably mounted in the second mounting groove 13 via a bearing seat and is connected to a rotating shaft 7. A worm 15 is rotatably mounted at the bottom end of the second mounting groove 13 via a bearing seat and is meshed with the worm gear 14.

[0031] The second motor 16 is installed on one side of the bottom of the second mounting slot 13, and the output end of the second motor 16 is connected to the worm gear 15 via a coupling.

[0032] The second motor 16 drives the worm 15 to rotate. Since the worm 15 is meshed with the worm wheel 14, the worm wheel 14 rotates together and drives the rotating shaft 7 to rotate.

[0033] One of the pair of brackets 3 has a controller 17 installed on one side.

[0034] The controller 17 is electrically connected to the first motor 12, the second motor 16 and the sensing mechanism 2 respectively, so as to facilitate the control of the overall circuit of the device.

[0035] The working principle of this embodiment is as follows: When using the coal mine rockburst prevention and monitoring early warning device, the staff first moves the device to the monitoring location. Then, according to the location to be monitored, the first motor 12 and the second motor 16 are turned on respectively. The first motor 12 drives a threaded rod 10 to rotate. Under the transmission action of a pair of synchronous pulleys 11, the pair of threaded rods 10 rotate synchronously. Then, under the limiting action of the first slide groove 4, a pair of first sliders 5 move up and down at the same time to adjust the height of the sensing mechanism 2. The second motor 16 drives the worm gear 15 to rotate. Since the worm gear 15 is meshed with the worm wheel 14, the worm wheel 14 rotates together and drives the rotating shaft 7 to rotate, thereby adjusting the angle of the sensing mechanism 2. When it is necessary to monitor other areas, the staff can adjust the position and angle of the sensing mechanism 2 again after moving the device to the designated location of the next area.
