Description

Technical Field

[0001] This utility model belongs to the field of tunnels, specifically relating to a tunnel ground pressure anomaly detection device. Background Technology

[0002] Roadways are an indispensable part of mining and exploration engineering. They are various passages drilled between the surface and the ore body, mainly used for transporting ore, drainage, ventilation, and providing necessary preparatory works for metallurgical equipment to extract ore. In addition, roadways are also used for the passage of pedestrians and equipment.

[0003] Existing roadway ground pressure anomaly detection devices have a fixed height, which makes them unsuitable for flexible installation in roadways of different heights. This limits the flexibility and practicality of the device and makes it difficult to fully meet the complex and ever-changing needs of roadway ground pressure detection. Therefore, a new roadway ground pressure anomaly detection device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a tunnel ground pressure anomaly detection device to solve the problems mentioned in the background art.

This allows the roadway detection device to adapt to roadways of various heights, fully meeting the complex and ever-changing roadway detection needs. The synchronously moving support plate can provide stable support for the adjusting rod, ensuring that the adjusting rod remains stable during detection and effectively guaranteeing the accuracy of the detection data. When transportation is required, the hydraulic cylinder can be controlled to move the support plate closer to the measuring rod, which can effectively reduce the overall size of the adjusting device and facilitate the transportation of the device to the installation location for installation.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-4This utility model provides a tunnel ground pressure anomaly detection device, including a measuring rod 1. An adjustment device 7 is provided on the surface of the measuring rod 1, and the adjustment device 7 includes an adjustment groove 701. A hydraulic cylinder 702 is fixedly connected inside the measuring rod 1. An adjustment slip ring 703 is fixedly connected to the output end of the hydraulic cylinder 702. Four lifting grooves 704 are formed on the surface of the measuring rod 1. Lifting rods 705 are slidably connected to the inner walls of the four lifting grooves 704 respectively. First limiting rotating rods 706 are fixedly connected to the other ends of the four adjustment slip rings 703 respectively. Connecting plates 707 are fixedly connected to the surfaces of the four first limiting rotating rods 706 respectively. Support plates 708 are rotatably connected inside the four first limiting rotating rods 706 respectively. Second limiting rotating rods 709 are rotatably connected inside the four support plates 708 respectively. Anti-slip bases 710 are fixedly connected to the tops of the four second limiting rotating rods 709 respectively. Each anti-slip base 710 has a guide rod 711 slidably connected inside. Each of the four guide rods 711 has a fixed insert rod 712 inserted inside. The tops of the four fixed insert rods 712 are fixedly connected to a force-applying link 713. By setting up a hydraulic cylinder 702 and a support plate 708, the hydraulic cylinder 702 can be operated according to the actual height of the roadway, precisely driving the adjusting rod 3 and the pressure detection plate 4 to rise and fall flexibly. This allows the roadway detection device to adapt to roadways of various heights, fully meeting the complex and ever-changing roadway detection needs. The synchronously moving support plate 708 provides stable support for the adjusting rod 3, ensuring the adjusting rod 3 remains stable during detection and effectively guaranteeing the accuracy of the detection data. When transportation is required, the hydraulic cylinder 702 is operated to move the support plate 708 closer to the measuring rod 1, effectively reducing the overall size of the adjusting device 7 and facilitating its transport to the installation location for installation.

[0024] The measuring rod 1 has a mounting base 2 at its bottom and an adjusting rod 3 inside.

[0025] The top of the adjusting rod 3 is equipped with a pressure detection plate 4, and the surface of the measuring rod 1 is equipped with a controller 5. One end of the controller 5 is equipped with an alarm 6.

[0026] The adjusting groove 701 is located inside the measuring rod 1, and the adjusting rod 3 slides on the inner wall of the adjusting groove 701.

[0027] The adjusting slip ring 703 slides on the inner wall of the adjusting slide groove 701, and one end of each of the four lifting slide rods 705 is fixedly connected to the surface of the adjusting slip ring 703.

[0028] Four guide rods 711 are inserted inside the mounting base 2, and a fixed rod 712 is inserted inside the mounting base 2. By setting an adjusting slip ring 703 and an adjusting groove 701, when the adjusting slip ring 703 moves in the adjusting groove 701, it can provide a limiting and guiding function for the connected adjusting rod 3, ensuring that the adjusting rod 3 remains stable during movement and avoiding deviation or shaking, thereby ensuring the stability of the adjusting device 7.

[0029] The working principle and usage process of this utility model are as follows: Based on the specific tunnel height, the hydraulic cylinder 702 is activated, synchronously driving the adjusting rod 3, adjusting slip ring 703, lifting slide rod 705, and first limit rotating rod 706 to perform lifting and lowering movements. During this process, the support plate 708 rotates on the surfaces of the first limit rotating rod 706 and the second limit rotating rod 709, and simultaneously slides along the surface of the guide slide rod 711. When the pressure detection plate 4 rises to contact the top of the tunnel, the hydraulic cylinder 702 is closed. At this time, the support plate 708 synchronously stops lifting and lowering. The pressure is detected by the controller 5 and the pressure detection plate 4. If an abnormality is detected in the bearing pressure at the top of the tunnel, the controller will activate the alarm 6 to sound an alarm. During the detection, the support plate 708 provides stable support for the adjusting rod 3, ensuring the stability of the adjusting rod 3 and thus guaranteeing the accuracy of the detection data. When disassembly and transportation are required, the fixed insert rod 712 is pulled out by applying force to the linkage 713, and the guide slide rod 711 is pulled out from the mounting base 2, realizing the separation of the mounting base 2 and the guide slide rod 711. Subsequently, the hydraulic cylinder 702 is activated to drive the support plate 708 to rise and move closer to the surface of the measuring rod 1, thereby reducing the overall volume and facilitating transportation.
