[0061] Compared with the related art, the tunnel-specific hydraulic drilling and milling machine provided by the present invention has the following beneficial effects:

[0062] Compared with the existing tunnel boring machines, this equipment has a simple overall structure and good maneuverability. It only requires one operator and can be equipped with a cutting milling head 820 and a rock drill bit 830 for rock tunnel excavation that are easy to install and disassemble, which greatly improves the progress of rock excavation and reduces the demand for energy and labor costs during the operation of the equipment.

[0063] Second embodiment:

[0064] See also Figure 7 and Figure 8Based on the tunnel-specific hydraulic drilling and milling machine provided in the first embodiment of the present application, the second embodiment of the present application proposes another tunnel-specific hydraulic drilling and milling machine. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. Specifically, the tunnel-specific hydraulic drilling and milling machine provided in the second embodiment of the present application is different in that the tunnel-specific hydraulic drilling and milling machine also includes:

[0065] A cooling box 900 is fixedly installed on the top of the main frame assembly 100, a partition 901 is installed on the inner wall of the cooling box 900, a filter plate 902 is installed on the top of the partition 901, and a fan 903 is installed on the partition 901, an aeration pipe 904 is installed on the output end of the fan 903, a fixed pipe 910 is installed on one side of the cooling box 900, a connecting hose 911 is installed on the input end of the fixed pipe 910, an adjusting member 920 is installed on the outer surface of the swing arm 710, a linkage plate 921 is fixedly installed on the output end of the adjusting member 920, a limiting disk 930 is fixedly installed on the top of the swing arm 710, an exhaust pipe 940 is installed on the top of the linkage plate 921, and an isolation filter 941 is fixedly installed on the inner wall of the exhaust pipe 940.

[0066] By arranging an adjustment member 920 on the outer surface of the swing arm 710, the adjustment member 920 can conveniently drive the linkage plate 921 to move up and down for adjustment, thereby conveniently driving the exhaust pipe 940 to move up and down for adjustment. When the exhaust pipe 940 moves downward, it is engaged with the surface of the limit plate 930, and the exhaust pipe 940 can normally exhaust air. When exhausting air, the dust and particles generated during the equipment advancement operation are attracted, and the attracted particles are blocked on the surface of the isolation filter 941. After the air enters the interior of the cooling box 900, it is first purified by the filter plate 902, and then purified by aeration to the water source. The purified gas is then discharged, thereby reducing the amount of dust in the working environment from the source. On the one hand, a good working field is obtained, and on the other hand, it is convenient to purify the breathing air and obtain good breathing air.

[0067] A water injection pipe is provided on the front of the cooling box 900 for adding water, and a sewage pipe is installed at the bottom of the cooling box 900 for replacing and cleaning the water inside the cooling box 900.

[0068] The filter plate 902 adopts the dust filter mesh plate structure of the prior art, and is used to filter the dust in the inhaled air.

[0069] The inner surface of the isolation filter 941 is paved with gauze to increase the dust-blocking effect of the isolation filter 941 when exhausting air.

[0070] The interior of the cooling box 900 is filled with filtered water source, the output end of the aeration pipe 904 is located inside the filtered water source, the filter plate 902 is installed on the input end of the fan 903, and the output end of the fixed pipe 910 is connected to the interior of the cooling box 900.

[0071] The air extraction pipe 940 is provided with two air inlets, and the surface of the limiting plate 930 is engaged with the inner surface of one of the air inlets.

[0072] When in use, the fan 903 is started first. The fan 903 sucks the dust and mist generated by the front end of the tunnel boring machine through the fixed pipe 910, the connecting hose 911 and the exhaust pipe 940. The dust particles after suction are collected above the limit plate 930. The gas is input into the water source through the aeration pipe 904, so that the gas is aerated and purified. After the gas is aerated and purified, it is directly discharged into the air, reducing the dust generated in the working environment.

[0073] When it is necessary to clean the dust collected above the limit plate 930, start the adjustment member 920, which drives the linkage plate 921 to move upward, and the linkage plate 921 drives the exhaust pipe 940 to move upward, and the air inlet at the bottom of the exhaust pipe 940 is separated from the surface of the limit plate 930, so that the particles stored in the exhaust pipe 940 are automatically discharged outward under the action of gravity, and the swing arm 710 that can be adjusted up and down can conveniently drive the particles stored above to automatically shake off downward, so as to facilitate automatic maintenance and management of the equipment.

[0074] Beneficial effects:

[0075] By arranging an adjustment member 920 on the outer surface of the swing arm 710, the adjustment member 920 can conveniently drive the linkage plate 921 to move up and down for adjustment, thereby conveniently driving the exhaust pipe 940 to move up and down for adjustment. When the exhaust pipe 940 moves downward, it is engaged with the surface of the limit plate 930, and the exhaust pipe 940 can normally exhaust air. When exhausting air, the dust and particles generated during the equipment advancement operation are attracted, and the attracted particles are blocked on the surface of the isolation filter 941. After the air enters the interior of the cooling box 900, it is first purified by the filter plate 902, and then purified by aeration to the water source. The purified gas is then discharged, thereby reducing the amount of dust in the working environment from the source. On the one hand, a good working field is obtained, and on the other hand, it is convenient to purify the breathing air and obtain good breathing air.

[0076] Furthermore, an air intake pipe 950 is installed at the output end of the cooling box 900. The air intake pipe 950 is a hose structure, and the output end of the air intake pipe 950 is fixedly installed on the surface of the operating room assembly 300. The input end of the air intake pipe 950 is interconnected with the interior of the cooling box 900, and the output end of the air intake pipe 950 is interconnected with the interior of the operating room assembly 300.

[0077] An exhaust port is provided on the cooling box 900, and the interior of the exhaust port corresponds to the interior of the air inlet pipe 950. The exhaust port is located below the partition 901 and is used to discharge the purified gas. After the gas is discharged, it is input into the interior of the operating room assembly 300 through the air inlet pipe 950 to provide supplementary internal pressure for the interior of the operating room, so that the internal pressure increases relatively. A ventilation hole is provided on the window plate of the operating room assembly 300, and the ventilation hole is used to discharge the gas after the internal pressure increases, so as to keep the interior of the operating room assembly 300 in a relatively constant pressure state. The internal pressure of the operating room assembly 300 is greater than the outdoor pressure, and the gas is continuously discharged to the outside, so that during the operation of the equipment as a whole, on the one hand, it can prevent the operator from inhaling dust during the operation and causing harm to the body. On the other hand, the internal and external pressure difference prevents dust from entering the interior of the operating room assembly 300, thereby ensuring the stability of the internal adjustment equipment, preventing dust from entering and affecting the active structure of the operating equipment, maintaining the stability of the equipment operation inside the operating room assembly 300, and providing a stable working environment for the operator.
