[0017] In this embodiment, the air inlet 7 is connected with one end of the filter box 1 through a flange, the air inlet end of the fan 4 is communicated with the other end of the filter box 1, the fan 4 is fixed on the installation flat plate 2 through a support, the air outlet end of the fan 4 is communicated with the air outlet 6 through the flexible air pipe 5, and the filtered air is discharged from the air outlet 6.
[0018] In this embodiment, a guide plate structure is arranged in the air inlet 7, and the air inflow resistance can be reduced by 20%. In this embodiment, the filter core 11 is made of a folded film-coated polyester fiber material and is arranged in a wave-shaped folded shape. The wave-shaped folded filter core 11 can increase the filtering area to three times that of a traditional filter core 11, effectively filter particles with a size of 0.3 μm, and intercept more than 99% of dust particles.
[0019] In this embodiment, the air outlet 6 is provided with a sound-absorbing diffusion device, which can uniformly diffuse the discharged air flow to the tunnel space.

[0021] In addition, in this embodiment, the track 3 adopts a double-track independent driving structure, which can provide a bearing capacity of up to 15 tons and adapt to a maximum 30° slope and complex road conditions such as mud and gravel.
[0022] The air inlet 7 has an opening diameter of 1.0 m.
[0023] The flexible air pipe 5 is made of a high-temperature-resistant and tear-resistant silica gel corrugated hose with a wall thickness of 5 mm, and has good flexibility and sealing performance.
[0024] The fan 4 is a power mechanism, which adopts a high-power axial fan 4 as the core. The fan 4 shell is made of high-strength alloy steel and is subjected to precise dynamic balance treatment.

[0025] Working principle
[0026] (1) Air power flow principle
[0027] When the fan 4 rotates at high speed, the axial blades form a negative pressure field at the air inlet end, so that the dust-containing air in the tunnel enters the filter box 1 through the air inlet 7 and the air inlet variable diameter 8 under the action of the pressure difference. Dust-containing air is pushed by the power of the fan 4 to pass through the filter core 11 inside the filter box 1 at a flow rate of 15-20 m / s, and the filtered clean air is discharged through the air outlet 6 to form a complete air flow path; (II) High-efficiency filtration principle The filter core 11 inside the filter box 1 adopts a combination of deep filtration and surface filtration. When dust-containing air passes through the filter core 11, dust particles are captured by the filter material due to effects such as inertial impact, interception, diffusion, and electrostatic adsorption; The nanoscale pore structure on the surface of the filter core 11 can effectively block fine dust penetration, ensuring that the discharged air meets the "Occupational Exposure Limits for Harmful Factors in the Workplace" standard; (III) Intelligent walking principle The dual-track independent drive system of the track 3 controls the speed difference of the two tracks 3 on both sides through a hydraulic proportional valve to realize agile operations such as turning in place; The on-board control system monitors parameters such as walking speed in real time, automatically adjusts the driving force according to the ground conditions, and ensures stable operation of the trolley under complex working conditions.
[0028] Specific working process
[0029] Equipment deployment: Transport the tunnel dust removal trolley to the tunnel construction site by transport vehicle, use the on-board hydraulic legs for horizontal calibration and stable support, connect the 380V industrial power supply and start the equipment self-checking program to ensure the normal function of each system; Positioning movement: The operator controls the track 3 operation through the electric control handle to move the trolley to the dust removal area; When encountering obstacles, the auxiliary camera and laser radar environment perception system can be enabled to achieve millimeter-level accurate positioning and obstacle avoidance; Dust removal operation: Start the fan 4, dust-containing air is quickly sucked from the air inlet 7, and enters the filter box 1 inside through the air inlet reducer 8; Under the continuous action of the fan 4, the filtered clean air is discharged from the air outlet 6 to form a purification area with a coverage radius of up to 5 meters; During the operation, the filter core 11 blockage sensor monitors the filtration resistance in real time. When the resistance exceeds the set threshold, the dust cleaning device is automatically started to remove dust on the surface of the filter core 11 by compressed air blowing; Region switching: After completing the dust removal in the current area, turn off the fan 4, move the trolley to the next operation point by operating the track 3, and repeat the above dust removal process; During the entire operation process, the equipment operation data (such as air volume, filtration efficiency, energy consumption, etc.) are uploaded to the remote monitoring platform in real time, which is convenient for management personnel to carry out operation and maintenance scheduling; Job end: after completing all dust removal tasks, turn off the power of the equipment, clean the filter core 11 inside the filter box 1 and the dust in the dust hopper 10, check the wear of the track 3 and the tightness of the connection of each part, fold the trolley to the transportation state, and wait for the next operation instruction.
