By arranging the bottom frame 3, the buffer pad 17, the column 22 and the spring 23 under the bottom plate 5, multiple shock absorption can be performed to improve the shock absorption effect, thereby providing a certain buffering and protective effect on the monitoring device body 1.

[0031] Embodiment 2: Based on Embodiment 1, a guide hole 12 is opened on the surface of the bottom plate 5, and the guide hole 12 is provided in four groups, and the four groups of guide holes 12 are respectively located at the four ends of the surface of the bottom plate 5, and the column 22 is fixed in the inner cavity 18, and the column 22 is provided in four groups, and the four groups of columns 22 are respectively located at the four ends of the inner cavity 18, and the column 22 and the guide hole 12 are slidably connected, the bottom plate 5 is located in the inner cavity 18, and the outer wall of the bottom plate 5 and the inner wall of the inner cavity 18 are slidably connected, and the spring 23 is located between the bottom frame 3 and the bottom plate 5, and one end of the spring 23 is fixedly connected to the bottom wall of the inner cavity 18, and the spring 23 is The other end is fixedly connected to the bottom plate 5, and a plurality of buffer pads 17 are provided, and the plurality of buffer pads 17 are evenly distributed in the inner cavity 18.

[0036] During use, when installing the monitoring device body 1, first move the monitoring device body 1 to the lifting seat 9, insert the four sets of guide rods 24 into the guide holes 35 of the side ears 30 accordingly, and the end faces of the guide rods 24 are chamfered to improve the smoothness of the connection. When the monitoring device body 1 is placed on the lifting plate, the limit hole 25 opened will correspond to the through hole 34. At this time, by holding the rotating cap 33 and rotating it, the limit rod 31 is driven to be screwed into the limit hole 25 and the through hole 34 to achieve the limitation of the monitoring device body 1. The anti-slip texture 32 opened on the surface of the rotating cap 33 can increase the friction during rotation and improve the stability during operation.

The rotating rod 44 is located below the pushing handle 7.

[0039] When in use, it is worth noting that the first chain 15 and the second chain 16 are both quick-release chains. When the operator is located at a certain side pushing assembly 500 and needs to adjust the height of the monitoring device body 1, the chain at a farther position is first disassembled before adjustment can be made. Secondly, when the device is moving, at least one of the first chain 15 and the second chain 16 is ensured to be in an installed state to ensure that the height of the monitoring device body 1 remains unchanged. The operation of the first adjustment assembly 300 is described below. The specific operation is as follows: the operator holds the turning handle 45 and rotates it, which drives the turning rod 44 and the worm 39 to rotate, and then under the meshing action of the worm 39 and the worm wheel 11, the worm wheel 11 will rotate synchronously, thereby rotating the first rotating column 14, and then driving the first sprocket 13 to rotate. Through the transmission action of the first chain 15, the upper sprocket 28 and the main column 27 are driven to rotate, thereby under the action of the screw connection, the threaded column 37 and the lifting seat 9 are moved;

[0040] The operation of the second adjustment component 400 is described below. The specific operation is as follows: the operator holds the turning handle 45 and turns it, which drives the turning rod 44 and the worm 39 to rotate, and then under the meshing action of the worm 39 and the worm wheel 11, the worm wheel 11 will rotate synchronously, thereby causing the second rotating column 20 to rotate, and then driving the second sprocket 19 to rotate, and through the transmission action of the second chain 16, the lower sprocket 29 and the main column 27 will be driven to rotate, thereby under the action of the screw connection, the threaded column 37 and the lifting seat 9 are moved, wherein, while the lifting seat 9 moves, the provided sliding rod 26 will be embedded in the sliding groove 10 and continuously slidably connected, providing guidance and support for the movement of the lifting seat 9, thereby adjusting the position of the monitoring device body 1, and the setting of the worm 39 and the worm wheel 11 can form a self-locking, to prevent the moving seat from moving without force;

The support plate 38 is in the shape of a "7". There are a plurality of support plates 38, and the plurality of support plates 38 are evenly distributed linearly on the surface of the frame plate 8.

[0042] When in use, due to the limited space inside the mine, two sets of pushing components 500 are set on the bottom plate 5. There is no need to turn the direction of the device. The pushing components 500 on both sides can realize the displacement of the entire device in different directions. The operator holds the handle and applies force, and cooperates with the four sets of universal wheels 4 set under the bottom frame 3 to realize the movement of the entire device. The several support plates 38 set can provide support on both sides of the frame plate 8, thereby improving the stability of the frame plate 8.

[0043] Working principle: In actual use, the monitoring device body 1 can be quickly and conveniently installed on the lifting seat 9 to improve the installation efficiency. The height of the monitoring device body 1 can be adjusted by using the set lifting component 200, the first adjustment component 300 and the second adjustment component 400 in conjunction with the transmission component 100 to increase the monitoring range. The pushing component 500 allows the entire device to be moved to improve the comprehensiveness of the monitoring. By arranging a bottom frame 3, a buffer pad 17, a column 22 and a spring 23 under the bottom plate 5, multiple shock absorption is performed to improve the shock absorption effect, thereby providing a certain buffering and protective effect for the monitoring device body 1, thereby avoiding the following problems: In the prior art, when monitoring the gas concentration inside the coal mine tunnel, the gas monitoring equipment is usually fixed in one place, which is inconvenient to adjust, and only the gas concentration at that place is monitored. This cannot fully reflect the gas concentration distribution inside the coal mine tunnel. On the other hand, due to the complex working conditions in the mine and the large vibration during operation, the monitoring device lacks a shock absorption mechanism, which is easily damaged.
