[0002] When carrying out construction work at the tunnel face, a construction work trolley needs to be placed there. Operators use the trolley as a support structure for the tunnel. Therefore, the construction work trolley device for the tunnel face is an important piece of tunnel construction equipment.

This increases the procedure for installing dust control devices, thus affecting tunnel excavation efficiency. This invention, through the technical feature of forming an isolation air curtain in the working area at the tunnel face, effectively explores and studies the technical problem of using mobile work vehicles as construction trolleys and requiring the use of exhaust pipes to discharge dust generated at the tunnel face to the outer side of the tunnel.

The operator stands on the plates to carry out the construction work, so that the fan part and the flocculant delivery pump are in working condition. The dust gas generated on the tunnel face is driven by the force of the fan part, causing the rope part to vibrate. The dust gas generated on the tunnel face enters the box part I through the rope part. The flocculant is sprayed into the gas-liquid mixing pipe part through the spray head. The dust gas generated on the tunnel face is transported to the gas-liquid mixing pipe part through the input pipe part. In the mixing pipe section, the flocculant is mixed with the dust gas generated at the working face to obtain a gas-liquid-solid three-phase mixture. The gas-liquid-solid three-phase mixture rotates at high speed in the centrifuge section. The dust particles bound by the flocculant flow downward along the inner wall of the centrifuge section and are discharged from the centrifuge section through the discharge hole. The gas that has discharged the dust particles is transported to box section II and box section III through the output pipe section. The gas that has discharged the dust particles is sprayed onto the lower end face of the frame section through the leakage window I, leakage window II, leakage window III and leakage window IV.

Remove them from the receiving hole and receiving groove, and rotate ear plate I, ear plate II, and rotating cylinder on the rod, so that the inner flat plate, middle arc plate, and outer flat plate are in an inclined state. After completing the inclination angle of the inner flat plate, middle arc plate, and outer flat plate, put the bolt of the connecting screw nut into the receiving hole and receiving groove, so that the nut of the connecting screw nut rotates on the bolt of the connecting screw nut, so that the flange of the connecting screw nut and the nut of the connecting screw nut act on the rotating cylinder respectively. On the peripheral side surface, the exhaust fan is placed on the outer side of the working face. When the ventilation windows I, II, III, and IV spray the dust-removing gas towards the lower end face of the frame, the dust-removing gas is sprayed towards the inner flat plate, the middle arc plate, the outer flat plate, and the ventilation net, putting the exhaust fan into working condition and spraying the dust-removing gas towards the working face. When the ventilation windows I, II, III, and IV have completed the process of removing the dust-removing gas... After the body is sprayed onto the lower end face of the frame, the exhaust fan is put into a non-working state. The outer clamping nut and the inner clamping nut located between the frame and the rod are rotated in opposite directions at the end of the rod, so that the outer clamping nut and the inner clamping nut between the frame and the rod are separated from the lug body of the frame. The outer clamping nut between the frame and the rod is separated from the end of the rod, and the end of the rod is removed from the lug body of the frame, thereby separating the support rod from the moving vehicle.

[0091] In verifying this invention, the inventors abandoned the existing technical features that all used mobile work platforms as construction trolleys and required exhaust pipes to discharge dust generated at the tunnel face to the outside of the tunnel. Instead, they first proposed a technical feature of forming an isolation air curtain in the working area at the tunnel face. This resulted in the first unexpected technical effect: purifying the air in the tunnel; the second unexpected technical effect: redistributing the purified air within the tunnel; and the third unexpected technical effect: isolating dusty air and ensuring the tunnel's safety. The environmental cleanliness achieved a fourth unexpected technical effect: a dust air purification and emission system consisting of dust collection box 2, dust collector 3, intermediate ventilation box 4, and end ventilation box 5 was implemented, and a continuous isolation air curtain was achieved in the tunnel, resulting in a fifth unexpected technical effect: a redistribution system consisting of support rod 6, air guide plate 7, ventilation net 8, and exhaust fan 91 was implemented, and a front and rear airflow pressure difference was achieved in the tunnel, resulting in a sixth unexpected technical effect: internal and external airflow were formed in the working area at the working face, preventing the dust gas generated at the working face from spreading outward.

This solves the technical problem of using a mobile work vehicle frame as a construction work trolley and needing to use an exhaust pipe to discharge the dust generated at the tunnel face to the outside of the tunnel, thus improving the tunnel excavation efficiency.

[0101] 2. Due to the design of the intermediate vent box 4 and the end vent box 5, the gas discharged from the dust body is purified and released again within the box.

[0102] 3. Due to the design of dust collection box 2, the dust and gas generated at the working face can be collected and recovered.

[0103] 4. Due to the design of support rod 6, air guide plate 7, ventilation net 8 and exhaust fan 91, the gas that discharges dust is redistributed.

[0104] 5. Due to the design of the connecting screw nut 9, the position between the air guide plate 7 and the ventilation screen 8 can be adjusted and installed.

[0105] 6. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of this numerical range has achieved very good technical effect.

[0106] 7. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.
