The connecting monitoring mechanism 3 is arranged on one side of the base 1, wherein the connecting monitoring mechanism 3 comprises a fixing pipe 31 fixedly installed on one side of the base 1, an adjusting monitoring component 32 is arranged on one side of the fixing pipe 31, and a fixing component 33 is also arranged on one side of the fixing pipe 31. The plurality of supports 2 are combined with each other to form a full-chamber support 2. When the connecting monitoring mechanism 3 is in use, the supports 2 at different positions can be positioned and fixed by adjusting the monitoring component 32, so as to adapt to supports 2 at different heights. When the support 2 is in use, the monitoring distance can be quickly adjusted by adjusting the monitoring component 32, so as to adapt to different monitoring requirements, thereby enhancing adaptability. When monitoring is performed, the fixing component 33 can be used to quickly and stably connect with the support 2 to be connected, so as to facilitate monitoring of the settlement of the support 2.

[0024] like Figure 2 and Figure 3As shown, the adjustment monitoring component 32 includes a moving rod 321 slidably mounted on one side of the fixed tube 31, the fixed component 33 is arranged on one side of the moving rod 321, a gas cylinder 325 is arranged on one side of the fixed tube 31, one side of the gas cylinder 325 is fixedly connected to the base 1, a movable block 322 is slidably mounted inside the fixed tube 31, a piston plate 326 is fixedly mounted on the bottom of the movable block 322, the output end of the gas cylinder 325 extends to the inside of the fixed tube 31, the piston plate 326 is located above the output end of the gas cylinder 325, a pressure sensor 323 is fixedly mounted on the top of the movable block 322, and a contact plate 324 is fixedly mounted on the output end of the pressure sensor 323, and the contact plate 324 is located on the moving block 322. The bottom of the rod 321 can be quickly connected and fixed to the surface of the bracket 2 through the fixing component 33 when in use. At this time, the movable rod 321 moves with the fixing component 33 and is positioned and fixed. When the monitoring distance needs to be adjusted, gas can be injected into the bottom of the piston plate 326 through the gas cylinder 325, and the movable block 322 and the pressure sensor 323 are pushed by the gas. After the movable block 322 and the pressure sensor 323 are pushed by the gas, real-time monitoring of different settlement distances can be achieved, so that the monitoring device can adapt to different monitoring needs. The adjustment monitoring component 32 also includes a first magnet 328 fixedly installed on one side of the movable rod 321 and the movable block 322. The fixed tube A slide groove 329 is fixedly installed on one side of 31, and two second magnets 3210 are slidably installed inside the slide groove 329. The two second magnets 3210 are respectively located on one side of the two first magnets 328. When the moving rod 321 and the movable block 322 move, the adjacent second magnets 3210 are synchronously driven to move inside the slide groove 329 through the first magnet 328 on one side. The change in the distance between the moving rod 321 and the pressure sensor 323 can be more intuitively understood through the two second magnets 3210 located on the outside, so as to facilitate the adjustment of the monitoring distance. A spring 327 is fixedly installed on the inner bottom wall of the fixed tube 31. The spring 327 is located at the piston plate 326. At the bottom, the top of the spring 327 contacts one side of the piston plate 326. The spring 327 at the bottom of the fixed tube 31 can be used to lift the movable block 322 when the movable block 322 is not in use and moves downward, so that the movable block 322 can be stably located above the output end of the air cylinder 325, thereby facilitating the use of the air cylinder 325. A rubber plate 3211 is fixedly installed at the bottom end of the moving rod 321. The rubber plate 3211 is located above the contact plate 324. When the moving rod 321 moves downward synchronously with the contact plate 324, the rubber plate 3211 at one end of the moving rod 321 can reduce the impact force on the contact plate 324, thereby reducing damage to the contact plate 324.

[0025] like Figure 2 and Figure 4As shown, the fixing assembly 33 includes a support rod 331 rotatably mounted on the surface of the moving rod 321, one end of the support rod 331 is fixedly mounted with a fixing plate 332, one side of the fixing plate 332 is slidably mounted with two clamping plates 333, a bidirectional screw 334 is installed between the two clamping plates 333, and the bidirectional screw 334 is threadedly connected to one side of the two clamping plates 333.

The fixing component 33 also includes a rubber sleeve 335 fixedly installed on the adjacent side of the two clamps 333. The two rubber sleeves 335 are both arranged in an arc shape. The surface of the rubber sleeve 335 is provided with a plurality of friction grooves 336. When the clamps 333 are clamped, the two rubber sleeves 335 can provide a more stable and reliable clamping effect. The arc shape of the rubber sleeve 335 can better adapt to the surface of the bracket 2. The plurality of friction grooves 336 on the surface of the rubber sleeve 335 can enhance the clamping stability, so that the fixing component 33 is safer and more reliable during monitoring and operation.

[0026] When the utility model is in use, the surface of the bracket 2 can be quickly connected and fixed by the fixing component 33. At this time, the moving rod 321 moves with the fixing component 33 and is positioned and fixed. When the monitoring distance needs to be adjusted, gas can be injected into the bottom of the piston plate 326 through the gas cylinder 325, and the movable block 322 and the pressure sensor 323 are pushed by the gas. After the movable block 322 and the pressure sensor 323 are pushed by the gas, real-time monitoring of different sedimentation distances can be achieved, so that the monitoring device can adapt to different monitoring needs. When the moving rod 321 and the movable block 322 move, the adjacent second magnet 3210 will be synchronously driven to move inside the slide groove 329 through the first magnet 328 on one side. The distance change between the moving rod 321 and the pressure sensor 323 can be more intuitively understood through the two second magnets 3210 located on the outside, thereby facilitating the adjustment of the monitoring distance. The bottom of the fixed tube 31 can be used to adjust the distance between the moving rod 321 and the pressure sensor 323. The spring 327 lifts the movable block 322 when the movable block 322 is not in use and moves downward, so that the movable block 322 can be stably located above the output end of the air cylinder 325, thereby facilitating the use of the air cylinder 325. When it is necessary to fix the movable rod 321 to one side of the bracket 2, the bidirectional screw 334 can be rotated to allow the bidirectional screw 334 and the two clamping plates 333 to perform threaded movement, and the two clamping plates 333 can be synchronously driven to approach each other to stably clamp and fix one side of the bracket 2, so that the movable rod 321 can be fixed to one side of the bracket 2 for monitoring. When the clamping plates 333 are clamped, two rubber sleeves 335 can be used to provide a more stable and reliable clamping effect. The arc shape of the rubber sleeve 335 can better adapt to the surface of the bracket 2, and multiple friction grooves 336 on the surface of the rubber sleeve 335 can enhance the clamping stability, making the fixing component 33 safer and more reliable during monitoring and operation.
