[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] Reference Figures 1 to 4 , this embodiment 1 includes a supporting mechanism 1, a clamping mechanism 2 and a gas detector 3, the clamping mechanism 2 is installed on the supporting mechanism 1, and the clamping mechanism 2 clamps the gas detector 3.

[0025] Specifically, the support assembly 11 includes a base 111, the top of the base 111 is fixedly connected to a support frame 112, the drive assembly 12 includes a ball screw 121 fixedly connected to the support frame 112 through a bearing, one end of the ball screw 121 extends to the outside of the support frame 112, that is, passes through the support frame 112, the part of the ball screw 121 that passes through the support frame 112 rotates coaxially with a driven gear 122, the support frame 112 is located below the ball screw 121 and is slidably connected to a guide rod 123, the guide rod 123 passes through a slider 124 and is slidably connected to the slider 124, and the slider 124 is threadedly connected to the ball screw 121.

[0026] In addition, the driving assembly 12 further includes a motor 125 fixedly connected to the outside of the support frame 112 , and a driving gear 126 coaxially rotates at the output end of the motor 125 , and the driving gear 126 is meshed with the driven gear 122 .

[0027] The lifting assembly 21 includes a hydraulic cylinder 211 fixedly connected to the bottom of the slider 124, and the output end of the hydraulic cylinder 211 is fixedly connected to a connecting plate 212. A group of limiting grooves 213 are symmetrically opened at both ends of the connecting plate 212, and a group of clamping assemblies 22 are respectively limited, embedded and slid in a group of limiting grooves 213 of the connecting plate 212.

[0028] As can be seen from the above, when in use, the device is moved to the ventilation port, the base 111 is fixed to the ground by a steel chisel, and then the gas detector 3 is clamped between the two clamping assemblies 22. By controlling the motor 125, the output end of the motor 125 drives the driving gear 126 to rotate, the driving gear 126 drives the driven gear 122 to rotate, and the driven gear 122 drives the ball screw 121 to rotate. The rotation of the ball screw 121 allows the slider 124 to move laterally stably under the guidance of the guide rod 123, thereby causing the gas detector 3 to move laterally. By controlling the hydraulic cylinder 211, the output end of the hydraulic cylinder 211 drives the connecting plate 212 to move upward or downward, and the connecting plate 212 drives the gas detector 3 between the two clamping assemblies 22 to move upward or downward, thereby allowing the gas detector 3 to be distributed in different positions, achieving comprehensive monitoring of different areas and more accurately understanding the ventilation conditions of the entire mine.

[0031] As can be seen from the above, by pulling the two clamping rods 221, the two clamping rods 221 move away from each other, the clamping rod 221 drives the sliding rod 222 to move and makes the spring 224 compressed, and the gas detector 3 is placed on the two support plates 223. Then the clamping rod 221 is released, and the spring 224 recovers its deformation and pushes the sliding rod 222 to make the two clamping rods 221 move toward each other, thereby clamping the gas detector 3, which is convenient for installation and disassembly of the gas detector 3.
