Description

Technical Field

[0001] The present invention belongs to the technical field of tunnel compressor units, and in particular relates to a compressor unit device for follow-up air supply in a tunnel excavation scenario. Background Art

[0002] The compressor unit plays the role of "power nerve" in tunnel excavation, operating throughout the entire process of excavation, support, ventilation, and monitoring. It forms a highly integrated collaborative network with the main engine, hydraulic system, and ventilation equipment. Properly configuring the compressor unit's parameters and linkage logic is key to ensuring tunnel construction efficiency, safety, and equipment life. It provides power for pneumatic equipment, driving pneumatic tools such as pneumatic drills, breakers, and pneumatic wrenches within the tunnel to assist in excavation, anchor installation, and equipment maintenance. Compressed air is delivered to the tools through pipelines, where it is converted into mechanical energy to complete the work. It participates in the tunnel ventilation and dust removal system, driving axial fans or pneumatic ventilation valves to regulate air circulation within the tunnel, expelling dust and harmful gases (such as methane) generated during construction while introducing fresh air. In a slurry shield, compressed air is used to maintain pressure balance within the air cushion chamber, working in conjunction with slurry pressure to support the excavation face and prevent collapse. The air pressure must be constantly matched to the water and soil pressure at the excavation face. During simultaneous grouting or secondary grouting, a pneumatic grouting pump uses compressed air to push a piston, injecting slurry into the gap between the segments and the surrounding rock to reinforce the ground. The compressed air pressure must be maintained at a constant 0.4-0.6 MPa to ensure a uniform grouting volume.

[0003] In the prior art, during tunnel excavation using pneumatic drilling and blasting, the compressor unit is located close to heavy vibration equipment, such as pneumatic drills / drilling rigs. The compressor unit provides power for the pneumatic drills / drilling rigs. In a tunnel excavation environment, space is limited, and the compressor is located near the high-frequency vibration source. The distance between the compressor unit and the heavy vibration equipment is small, or even close, and the distance between the compressor unit and the heavy equipment is less than the critical resonance distance. In hard rock formations, the vibration transmission efficiency is greater than 60%. When the distance between the equipment is less than 1.5 meters, the vibration coupling degree increases sharply. Taking the compressor and pneumatic drill as an example, the operating frequency of the compressor is 18-25Hz, and the operating frequency of the pneumatic drill is 20-25Hz. When the two devices are too close, their operating frequencies may overlap, causing the equipment to resonate. During structural resonance, the vibration amplitude and speed are several times higher than usual. When resonance occurs, the measurement accuracy of precision equipment decreases, mechanical components are damaged, and in severe cases, cracks may appear on the inner wall of the tunnel.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] See also Figures 1-9 , a compressor unit device for follow-up air supply in a tunnel excavation scenario, includes a protection box 1, a buffer component 3 and a walking component 5. The buffer component 3 is installed on the outer wall of the protection box 1. The buffer component 3 includes a buffer tank 31. An air guide component 4 is installed inside the buffer component 3. During vibration, the buffer tank 31 vibrates and drives the air guide component 4 to guide air outward. The air guide component 4 includes a fixed cylinder 41. The buffer tank 31 vibrates with the equipment, driving the fixed cylinder 41 to work, and guiding the gas inside the fixed cylinder 41 to the inside of the walking component 5. The walking component 5 is installed at the bottom of the protection box 1. A motion component 7 is installed at the bottom of the walking component 5. The motion component 7 includes an anti-skid plate 72 and an anti-skid protrusion 73. The anti-skid protrusion 73 has multiple anti-skid protrusions distributed and installed at the bottom of the anti-skid plate 72, and the anti-skid plate 72 is located below the walking component 5 and contacts the ground. The walking component 5 drives the anti-skid plate 72 to reciprocate, and drives the protection box 1 to move through the contact between the anti-skid plate 72 and the ground.

[0039] Specifically, when the compressor is too close to other equipment, such as a tunnel boring machine, the buffer pad 34 of the buffer assembly 3 can first contact the outer wall of the tunnel boring machine. The internal structure of the buffer assembly 3 can effectively prevent the two equipment from directly contacting each other, thereby reducing the transmission of vibration and achieving the function of initially reducing resonance.

[0040] It should be noted that vibration will also be transmitted through the surrounding environment. When the buffer component 3 vibrates, the characteristic that vibration will cause the device to move in all directions is used to inflate the device through the fixed cylinder 41. The gas discharged from the fixed cylinder 41 is transmitted outward through the connecting pipe 46, and finally the driving component 6 is driven by the gas. When the driving component 6 is working, it will drive the anti-skid plate 72 to move back and forth. Due to the use of a cam structure, the movement trajectory of the anti-skid plate 72 is constantly forward, thereby driving the protective box 1 to move forward, so that the protective box 1 and the tunneling machine gradually move away, thereby eliminating the possibility of resonance and effectively protecting the equipment.

[0041] It should be noted that, in general, variable frequency devices can be used to control the frequency of compressor units and other vibration equipment to effectively prevent resonance. Adding a variable frequency drive can ignore the distance between devices and allow devices to be close together without resonance. However, in tunnel excavation scenarios, work is carried out inside the tunnel, and a large amount of dust and water vapor fills the tunnel environment. The high dust concentration and high humidity in the tunnel will affect the variable frequency drive, thereby greatly reducing the service life of the variable frequency drive. In addition, the variable frequency drive is a precision device with an internal microprocessor (CPU), power semiconductor devices (such as IGBT, IPM, etc.), high-precision sensors, filter circuits, etc. These components are highly integrated. However, the equipment used in tunnel excavation will generate vibrations of varying degrees. The variable frequency drive is inside the equipment and will inevitably be affected by the vibrations. Once the variable frequency drive is damaged, it is difficult to repair and cannot be used for a long time in a tunnel excavation environment.

[0042] It should be noted that the present application adopts a purely mechanical structure to avoid resonance between devices and can be used in the harsh environment of the tunnel for a long time.

[0043] A cooling fan 11 is installed on the top of the protective box 1, a universal wheel 12 is installed on the bottom of the protective box 1, a vibration sensor 13 is installed on the top of the protective box 1, a compressor 2 is installed on the inner bottom wall of the protective box 1, a controller 21 is installed on the inner top wall of the protective box 1, and a connector 22 is installed on the inner wall of the protective box 1, and the connector 22 is connected to other equipment through a pipeline.

[0044] Specifically, the heat dissipation fan 11 dissipates heat from the interior of the protective box 1 , the compressor and the connector 22 facilitate connection of other devices to the compressor 2 , and the vibration sensor 13 can monitor the vibration frequency of the device.

[0045] The buffer assembly 3 includes a fixed shell 30 installed on the outer wall of the protective box 1, a buffer tank 31 is installed on the inner wall of the fixed shell 30, a buffer spring 32 is installed on the inner wall of the buffer tank 31, a buffer rod 33 is installed through the outer wall of the buffer tank 31, a buffer pad 34 is installed at one end of the buffer rod 33, and a sealing plate 35 is installed at the other end of the buffer rod 33.

[0046] Specifically, multiple buffer assemblies 3 can be installed and distributed around the protective box 1, thereby effectively separating other devices from the device itself, preventing direct contact and reducing the possibility of vibration transmission. When the vibration amplitude is large, the buffer pad 34 drives the buffer rod 33 to move, and the buffer rod 33 drives the sealing plate and buffer spring 32 to move, thereby achieving a buffering function and preventing damage to the device.

[0047] It should be noted that, in this device, the buffer tank 31 may be filled with damping fluid, and a damping device may be provided inside the fixed shell 30 to better achieve the buffering function.

[0048] The inner wall of the fixed shell 30 is equipped with multiple air guide components 4. The air guide components 4 include a U-shaped groove 40, a fixed cylinder 41 is installed on the top of the U-shaped groove 40, and two circular holes 42 are provided on the outer wall of the fixed cylinder 41, and one of the two circular holes 42 is used as an air inlet and the other as an exhaust hole, and a one-way valve is installed between the air inlet and the exhaust hole. A lifting rod is installed through the bottom of the fixed cylinder 41, and a return spring 43 is installed around the outer wall of the lifting rod. An extrusion rod 44 is installed on the top of the lifting rod, and an exhaust plate is installed at the bottom of the lifting rod. A connecting pipe 46 is installed through the outer wall of the U-shaped groove 40, and the connecting pipe 46 is connected to the exhaust hole of the fixed cylinder 41. A plurality of vibration rods 45 are installed on the outer wall of the buffer tank 31, and the bottom end of the vibration rod 45 is located at Inside the U-shaped groove 40, the walking assembly 5 includes a driving box 50 installed at the bottom of the protective box 1, and a fixed plate 51 is installed on the inner bottom wall of the driving box 50, and a slave cylinder 52 is installed on the outer wall of the fixed plate 51. An air intake pipe 53 is installed on the outer wall of the slave cylinder 52, and the air intake pipe 53 is connected to the connecting pipe 46. A movable plate 54 is installed at the telescopic end of the slave cylinder 52, and a gear groove 55 is provided on the top of the movable plate 54. A driving gear 56 is installed on the outer wall of the fixed plate 51, and the driving gear 56 is engaged with the gear groove 55. Two fixed grooves 57 are provided at the bottom of the driving box 50, an exhaust pipe 58 is installed on the outer wall of the slave cylinder 52, and an electric control valve is installed on the outer wall of the exhaust pipe 58. An alarm device 59 is installed on the inner wall of the driving box 50.

[0049] Specifically, when the vibration amplitude is large, the buffer tank 31 will also vibrate, and the buffer tank 31 will drive the vibration rod 45 to vibrate. Since the vibration direction is not fixed, the vibration amplitude of the vibration rod 45 will be large, thereby squeezing the extrusion rod 44, and the lifting rod will descend to drive the return spring 43 to contract. The exhaust plate squeezes the gas inside the fixed cylinder 41, so that the air is transported outward through the exhaust hole and the connecting pipe 46 to realize the exhaust function.

[0050] It should be noted that the exhausted air enters the slave cylinder 52 through the connecting pipe 46 and the air intake pipe 53, causing the pressure inside the slave cylinder 52 to increase, and then the telescopic end of the slave cylinder 52 extends, driving the movable plate 54 to move, and then the gear groove 55 engages with the driving gear 56, driving the driving gear 56 to rotate, and the rotation of the driving gear 56 drives the rotating shaft 60 to rotate, so that the driving assembly 6 starts to work.

[0051] It should be noted that, under normal conditions, the air intake pipe 53 exhausts gas into the slave cylinder 52, and then the gas is discharged from the exhaust pipe 58. At this time, the electric control valve is in the open state. When the vibration sensor 13 detects that the vibration frequency is much higher than the normal frequency, the electric control valve is closed, and the exhaust pipe 58 no longer exhausts gas, so that the slave cylinder 52 starts to work. When one end of the movable plate 54 contacts the alarm 59, the alarm 59 adopts a pressure trigger structure, and one end of the movable plate 54 contacts the alarm 59, so that the alarm 59 makes a sound to warn the surrounding staff, thereby facilitating the staff to shut down the machine for timely maintenance.

[0052] The outer wall of the other side of the fixed plate 51 is equipped with a driving assembly 6, which includes a rotating shaft 60 coaxially connected to the driving gear 56, a cam 61 is installed on the outer wall of the rotating shaft 60, and a connecting rod 62 is installed on the outer wall of the fixed plate 51. One end of the connecting rod 62 is movably connected to the cam 61 through a pin, and the other end of the connecting rod 62 is equipped with a driving block 65. The bottom of the driving block 65 is equipped with a moving assembly 7, and the outer walls of the fixed plate 51 are respectively equipped with a transverse limiting rail 64 and a longitudinal limiting rail 63, and the driving block 65 moves on the transverse limiting rail 64 and the longitudinal limiting rail 63. The moving assembly 7 includes a transverse plate 70 installed at the bottom of the driving block 65, and a plurality of connecting columns 71 are installed at the bottom of the transverse plate 70. The bottom of the connecting column 71 is equipped with an anti-skid plate 72, and the bottom of the anti-skid plate 72 is distributed with a plurality of anti-skid protrusions 73. The size of the anti-skid plate 72 is smaller than that of the fixing groove 57.

[0053] Specifically, the rotation of the rotating shaft 60 drives the cam 61 to rotate, the cam 61 drives the connecting rod 62 to move back and forth, and the movement of the connecting rod 62 drives the driving block 65 to move, forming a forward movement trajectory. When the driving block 65 moves downward, it drives the cross plate 70 downward, so that the anti-slip plate 72 and the anti-slip protrusion 73 contact the ground. As the cam 61 rotates, the anti-slip plate 72 continues to squeeze downward, so that the protective box 1 is lifted up, thereby driving the protective box 1 away from other equipment through the action of the cam 61 and the connecting rod 62, and no personnel supervision is required, reducing the workload of the staff.

[0054] Working principle: first, multiple buffer components 3 can be installed and distributed around the protective box 1, so as to effectively separate other devices from the device, prevent direct contact, and reduce the possibility of vibration transmission. When the vibration amplitude is large, the buffer pad 34 drives the buffer rod 33 to move, and the buffer rod 33 drives the sealing plate and the buffer spring 32 to move, thereby realizing the buffer function to prevent the device from being damaged. When the vibration amplitude is large, the buffer tank 31 will also vibrate, and the buffer tank 31 drives the vibration rod 45 to vibrate. Since the vibration direction is not fixed, the vibration amplitude of the vibration rod 45 will be large, thereby squeezing the extrusion rod 44, and the lifting rod descends to drive the reset spring 43 to contract, and the exhaust plate squeezes the gas inside the fixed cylinder 41, so that the air is transported outward through the exhaust hole and the connecting pipe 46, realizing the exhaust function, and the exhausted air passes through the connecting pipe 46 and the inlet The air pipe 53 enters the driven cylinder 52, causing the pressure inside the driven cylinder 52 to increase, and then the telescopic end of the driven cylinder 52 extends, driving the movable plate 54 to move, and then the gear groove 55 engages with the driving gear 56, driving the driving gear 56 to rotate, and the driving gear 56 rotates and drives the rotating shaft 60 to rotate, so that the driving assembly 6 starts to work, and the rotation of the rotating shaft 60 drives the cam 61 to rotate, and the cam 61 drives the connecting rod 62 to move back and forth, and the movement of the connecting rod 62 drives the driving block 65 to move, forming a forward movement trajectory. When the driving block 65 moves downward, it drives the cross plate 70 downward, so that the anti-skid plate 72 and the anti-skid protrusion 73 contact the ground. As the cam 61 rotates, the anti-skid plate 72 continues to squeeze downward, so that the protective box 1 is lifted up, thereby driving the protective box 1 away from other equipment through the action of the cam 61 and the connecting rod 62.
