Description

Technical Field

[0001] This invention relates to the technical field of tunnel excavation, specifically to an integrated blasting and excavation trolley for hydropower and water conservancy projects. Background Technology

[0002] As hydropower and water conservancy tunnel projects develop towards deeper burial, longer distances, and larger cross-sections, blasting excavation and continuous muck removal have become the mainstream operating modes. While high-speed tunneling brings high efficiency, it also instantly releases a large amount of high-temperature smoke and dust and harmful particles, which accumulate rapidly in narrow, enclosed spaces, seriously restricting subsequent processes and personnel safety.

[0003] Existing technologies generally employ a single fan for dust extraction or a localized water curtain for dust suppression. However, these technologies have drawbacks. The fans are fixed in their placement, and the suction port is far from the blast source, allowing high concentrations of smoke and dust to spread. Water curtains only suppress some dust and can easily obstruct the passage of slag removal vehicles. Temporary ventilation ducts are frequently moved, have poor sealing, and have a high system leakage rate, often resulting in "extraction and leakage at the same time." The smoke extraction efficiency is less than 40%, and a long waiting period is required after the blast before construction can resume.

[0004] Therefore, there is an urgent need for an integrated technical solution that can achieve "instant sealing, efficient concentration, and precise smoke extraction" during the tunnel blasting and slag removal stages, so as to completely solve the technical problems of rapid smoke diffusion, low smoke extraction efficiency, and long operation downtime. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide an integrated blasting and excavation trolley for hydropower and water conservancy projects, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated blasting and excavation trolley for hydropower and water conservancy projects, comprising a trolley frame, a robotic arm located at one end of the top of the trolley frame, a closed smoke exhaust device at the other end, a movable smoke exhaust device located at the execution end of the robotic arm, and a drilling and excavation component. The closed smoke exhaust device includes a vertical rod located at the top of the trolley frame, two arc-shaped positioning frames symmetrically arranged on both sides of the vertical rod and hinged to the vertical rod, and an extended sealing component located on the outer edge of the arc-shaped positioning frames. The mobile smoke exhaust device includes a smoke sealing plate located on the inner edge of the arc-shaped positioning frame, a smoke exhaust pipe component located on the side of the smoke sealing plate away from the robotic arm, and a driving component located at the bottom of the trolley frame for driving the arc-shaped positioning frame to rotate; the mobile smoke exhaust device includes two lifting control components symmetrically located at the execution end of the robotic arm, and two air supply components symmetrically located on the trolley frame, the air inlet end of the air supply component being connected to the execution end of the lifting control component, and the exhaust end of the air supply component extending into the smoke exhaust pipe component.

[0007] According to one embodiment of the present invention, the extended sealing component includes a smoke-sealing cloth and an electromagnetic plate disposed on the outer edge of the arc-shaped positioning frame, a plurality of guide sleeves equidistantly arranged along the outer wall of the arc-shaped positioning frame, a guide post having one end slidably connected to the guide sleeve and the other end penetrating the electromagnetic plate, and a magnetic block sleeved on the outer wall of the guide post and located on the side of the electromagnetic plate away from the guide sleeve; the end of the guide post is connected to the outer edge of the smoke-sealing cloth.

In this preferred embodiment, smoke sealing can be achieved by both the rigid plate and the flexible strips. The flexible strips can avoid obstacles while sealing smoke, facilitating the unfolding or folding of the arc-shaped positioning frame. At the same time, the flexible strips can also seal smoke while the material conveyor belt is discharging slag.

[0009] According to one embodiment of the present invention, the smoke exhaust pipe component includes a plurality of exhaust pipes connected at one end to the rigid plate, and an air inlet pipe connected at one end to the rigid plate; the exhaust pipes are located at the top of the rigid plate, and the air inlet pipe is located at the bottom of the rigid plate. In this preferred embodiment, the smoke exhaust pipe component facilitates connection with the air supply system and negative pressure system outside the tunnel, facilitating air intake and smoke exhaust.

[0010] According to one embodiment of the present invention, the driving component includes an L-shaped rod with one end connected to the outer wall of the arc-shaped positioning frame and the other end penetrating the trolley frame and extending to the lower part of the trolley frame; an arc-shaped gear plate disposed at the bottom of the L-shaped rod; a stepper motor fixed to the bottom of the trolley frame by a support frame; and a driving gear disposed at the actuating end of the stepper motor and meshing with the arc-shaped gear plate. In this preferred embodiment, the driving component enables the stable opening or closing of the arc-shaped positioning frame.

[0011] According to one embodiment of the present invention, a water mist component is further provided on the side of the smoke-sealing plate near the robotic arm. The water mist component includes an arc-shaped spray pipe disposed on the outer wall of the rigid plate and a linear spray pipe horizontally disposed on the outer wall of the rigid plate and located at the bottom of the rigid plate. Both the arc-shaped spray pipe and the linear spray pipe are connected to an electrically controlled valve, which is connected to a water source pipe. In this preferred embodiment, the water mist component can achieve water mist dust suppression during blasting and slag removal.

[0012] According to one embodiment of the present invention, the drilling and excavation component includes a base platform hinged at the bottom to the actuator of the robotic arm, a rotating plate disposed on the top of the base platform, a movable frame slidably connected at the bottom to the top of the rotating plate, a drill bit disposed at one end of the movable frame, and an excavation bucket disposed at the other end; it also includes two material conveyor belts symmetrically disposed on the top of the trolley frame. In this preferred embodiment, the drilling and excavation component enables drilling within the tunnel, facilitating the installation of blasting explosives and the excavation and removal of slag after blasting.

[0013] According to one embodiment of the present invention, the lifting control component includes a horizontal plate disposed on the outer wall of the base platform, two winches symmetrically disposed on the horizontal plate, a self-locking motor disposed on the horizontal plate for driving the winches to rotate, an arc-shaped limiting plate disposed at the bottom of the horizontal plate, and a lifting ring located below the arc-shaped limiting plate and connected to the winches by a rope. In this preferred embodiment, the lifting control component enables stable lifting of the air inlet end of the air supply component.

[0014] According to one embodiment of the present invention, the gas conveying component includes a fan disposed on the top of the trolley frame, a first pipe disposed at the air inlet end of the fan, and a second pipe disposed at the air outlet end of the fan; the outer wall of the first pipe is connected to the inner ring of the lifting ring, and the end of the second pipe extends into the air inlet pipe. In this preferred embodiment, the gas conveying component facilitates the direct delivery of high-concentration smoke to the smoke exhaust pipe component.

[0015] According to one embodiment of the present invention, a smoke detection component is further provided on the outer wall of the base platform, the smoke detection component including a smoke concentration detector provided on the outer wall of the base platform. In this preferred embodiment, the smoke detection component facilitates the detection of smoke concentration.

[0016] In summary, the present invention has the following main beneficial effects: During hydropower and water conservancy construction, a large amount of high-temperature and high-density smoke and dust is generated instantaneously during the tunnel blasting and muck removal stages. Traditional equipment suffers from severe diffusion, low visibility, and work stoppages due to inadequate sealing, single smoke exhaust path, and difficulty in fixed-point extraction. The technical solution in this invention effectively solves the technical problem of timely and efficient smoke and dust removal during tunnel blasting and muck removal by coupling a dual system of "closed smoke exhaust device plus mobile smoke exhaust device". The arc-shaped positioning frame unfolds outward under the drive of a stepper motor and gear pair, and the rigid plate and flexible strip form the first ring barrier; the extended sealing component makes the smoke sealing cloth fit the tunnel wall in real time with the guide column, eliminating gaps and achieving complete sealing, creating the prerequisite for subsequent centralized smoke exhaust. Within the enclosed area, multiple exhaust pipes at the top are connected to a negative pressure system, utilizing the natural upward movement of smoke for high-level extraction; fresh airflow is simultaneously introduced through the bottom air intake pipe, forming a directional flow field of "upward extraction and downward pressure," which improves smoke extraction efficiency many times over compared to single-point extraction. The lifting control component at the end of the robotic arm can quickly send the telescopic and folding first pipe to the area with the highest concentration based on the data from the smoke concentration detector; the fan directly injects the high-concentration smoke into the exhaust pipe of the closed area through the second pipe to achieve mobile point suction and efficient smoke removal; The curved and linear spray nozzles automatically open at the moment of blasting, causing water mist particles to collide and settle with the smoke and dust, reducing dust concentration and suppressing sparks, thus protecting personnel and equipment safety. The flexible belt can remain closed during slag removal while allowing the material conveyor belt to operate continuously.

[0017] This technical solution achieves efficient smoke and dust removal during tunnel blasting and muck removal through mechanical enclosure, combined with double-layer smoke exhaust and mobile point suction, plus water mist dust suppression. Attached Figure Description

Multiple guide sleeves 233 are equidistantly arranged along the outer wall of the arc-shaped positioning frame 22. A guide post 234 has one end slidably connected to the guide sleeve 233 and the other end penetrating the electromagnetic plate 232. A magnetic block 235 is sleeved on the outer wall of the guide post 234 and located on the side of the electromagnetic plate 232 away from the guide sleeve 233. The end of the guide post 234 is connected to the outer edge of the smoke-sealing cloth 231. The smoke-sealing plate 24 includes a rigid plate 241 located on the inner edge of the arc-shaped positioning frame 22, and multiple guides linearly arranged at the bottom of the rigid plate 241. The flexible strip 242, the exhaust pipe component 25 includes multiple exhaust pipes 251 with one end connected to the rigid plate 241, and an intake pipe 252 with one end connected to the rigid plate 241; the exhaust pipes 251 are located at the top of the rigid plate 241, and the intake pipes 252 are located at the bottom of the rigid plate 241; the drive component 26 includes an L-shaped rod 261 with one end connected to the outer wall of the arc-shaped positioning frame 22 and the other end penetrating through the trolley frame 10 and extending to the lower part of the trolley frame 10; an arc-shaped gear plate 262 is provided at the bottom of the L-shaped rod 261 and is fixed to the trolley frame 10 by a support frame. The bottom includes a stepper motor 263 and a drive gear 264 located at the actuating end of the stepper motor 263 and meshing with the arc-shaped gear plate 262. It also includes a water mist component 27 located on the side of the smoke sealing plate 24 near the robotic arm 11. The water mist component 27 includes an arc-shaped spray pipe 271 located on the outer wall of the rigid plate 241 and a linear spray pipe 272 horizontally located on the outer wall of the rigid plate 241 and at the bottom of the rigid plate 241. Both the arc-shaped spray pipe 271 and the linear spray pipe 272 are connected to an electric control valve 273, which is connected to a water source pipe 274.

[0025] It should be noted that in this embodiment, when smoke and dust are generated in the tunnel due to blasting or excavation, the driving component 26 drives the arc-shaped positioning frame 22 to rotate and unfold, the extended sealing component 23 seals the gap between the inner wall of the tunnel and the arc-shaped positioning frame 22, and the rigid plate 241 and the flexible strip 242 seal the inner edge of the arc-shaped positioning frame 22 to block the smoke, thereby achieving complete smoke sealing, effectively preventing the smoke from spreading in the tunnel, and the concentrated smoke is more convenient to be discharged efficiently. After the sealing is completed, the negative pressure system connected to the exhaust pipe 251 outside the tunnel sucks up the smoke, and the air supply system connected to the air inlet pipe 252 provides airflow. The exhaust pipe 251 is set at a high position, and the physical phenomenon of the natural rise of smoke is used to achieve rapid smoke and dust discharge. Furthermore, when the extended sealing component 23 is working, during the extended sealing process, the electromagnetic plate 232 is energized to generate a repulsive force with the same polarity as the magnetic block 235. The repulsive force pushes the guide post 234 to move and extend, and the guide post 234 drives the smoke sealing cloth 231 to unfold. When the smoke sealing cloth 231 is recycled, the electromagnetic plate 232 is energized and generates an attractive force with the magnetic block 235 of opposite polarity. The attractive force drives the guide post 234 to move and retract, and the guide post 234 drives the smoke sealing cloth 231 to be recycled. Furthermore, when the drive component 26 is working, the stepper motor 263 drives the drive gear 264 to rotate, and the drive gear 264 drives the arc-shaped positioning frame 22 to rotate around the vertical rod 21 through the arc-shaped gear plate 262 and the L-shaped rod 261. Furthermore, during blasting, the arc-shaped spray pipe 271 and the linear spray pipe 272 can simultaneously spray water mist to suppress dust. When the material conveyor belt 126 outputs slag through the flexible strip belt 242, the linear spray pipe 272 can suppress dust. Water pipe 274 can be connected to a water supply system installed on the trolley frame 10. After the electric control valve 273 and the water supply system are turned on, water can flow into the arc-shaped spray pipe 271 and the linear spray pipe 272.

[0026] Please refer to the appendix for details. Figure 2 , 3As shown in Figure 8, in another preferred embodiment of the present invention, the mobile smoke exhaust device 30 includes two lifting control components 31 symmetrically arranged on the execution end of the robotic arm 11, and two air supply components 32 symmetrically arranged on the trolley frame 10. The air inlet end of the air supply component 32 is connected to the execution end of the lifting control component 31, and the exhaust end of the air supply component 32 extends into the smoke exhaust pipe component 25. The lifting control component 31 includes a horizontal plate 311 disposed on the outer wall of the base platform 121, two winches 312 symmetrically arranged on the horizontal plate 311, a self-locking motor 313 disposed on the horizontal plate 311 and used to drive the winches 312 to rotate, and a self-locking motor 313 disposed on the horizontal plate 311. The bottom arc-shaped limiting plate 314 and the lifting ring 315 located below the arc-shaped limiting plate 314 and connected to the winch 312 by ropes; the air supply component 32 includes a fan 321 located on the top of the trolley frame 10, a first pipe 322 located at the air inlet end of the fan 321, and a second pipe 323 located at the exhaust end of the fan 321; the outer wall of the first pipe 322 is connected to the inner ring of the lifting ring 315, and the end of the second pipe 323 extends into the air inlet pipe 252; it also includes a smoke detection component 33 located on the outer wall of the base platform 121, and the smoke detection component 33 includes a smoke concentration detector 331 located on the outer wall of the base platform 121.

[0027] It should be noted that in this embodiment, when smoke is discharged, the mobile smoke exhaust device 30 can perform fixed-point smoke exhaust. The lifting control component 31 drives the end of the first pipe 322 to move to the end of the robotic arm 11. At this time, the controller receives the smoke concentration information measured by the smoke concentration detector 331, and after analyzing the smoke concentration information, triggers the robotic arm 11 to move the end of the first pipe 322 to the area where the smoke concentration is higher than the set value. The fan 321 is turned on, and the high-concentration smoke can be directly discharged into the exhaust pipe 251 through the first pipe 322, the fan 321 and the second pipe 323. The first pipe, 322, is a telescopic folding pipe; Furthermore, when the lifting control component 31 is working, the self-locking motor 313 drives the winch 312 to rotate, and the winch 312 drives the lifting ring 315 to move through the rope until the outer wall of the lifting ring 315 abuts against the arc-shaped limit plate 314, at which point the self-locking motor 313 self-locks, so as to complete the lifting and positioning work of the end of the first pipe 322.

[0028] The working principle of this invention is as follows: The trolley frame 10 moves along a set route inside the tunnel via the bottom track. The robotic arm 11 and the drilling and excavation component 12 work together to drill or excavate the inner wall of the tunnel. After drilling, it is convenient to install explosives. The excavated slag can be transported via the material conveyor belt 126. The robotic arm 11 can be composed of a drive turntable, a telescopic arm, a first hydraulic cylinder, and a second hydraulic cylinder. The motor at the bottom of the trolley frame 10 can drive the drive turntable to rotate. The telescopic arm can be extended and retracted by hydraulic drive. The extension and retraction of the actuator end of the first hydraulic cylinder can change the tilt angle of the telescopic arm. The extension and retraction of the actuator end of the second hydraulic cylinder can change the tilt angle of the base platform 121. When the drilling and excavation component 12 is working, the rotating plate 122 can be driven by a motor located at the bottom of the base platform 121. The third hydraulic cylinder on one side of the rotating plate 122 can drive the moving frame 123 to move. The drill bit 124 at one end of the moving frame 123 can be driven by a motor built into the moving frame 123 to realize drilling. The excavation bucket 125 at the other end of the moving frame 123 can be driven by a fourth hydraulic cylinder on the moving frame 123 to realize excavation. When smoke and dust are generated in the tunnel due to blasting or excavation, the drive component 26 drives the arc-shaped positioning frame 22 to rotate and unfold. The extension sealing component 23 seals the gap between the inner wall of the tunnel and the arc-shaped positioning frame 22. The rigid plate 241 and the flexible strip 242 seal the inner edge of the arc-shaped positioning frame 22 to block the smoke, thereby achieving complete smoke sealing, effectively preventing the smoke from spreading in the tunnel, and making it easier to efficiently discharge the concentrated smoke. After the sealing is completed, the negative pressure system connected to the exhaust pipe 251 outside the tunnel sucks up the smoke, and the air supply system connected to the air inlet pipe 252 provides airflow. The exhaust pipe 251 is set at a high position, and the physical phenomenon of the natural rise of smoke is used to achieve rapid smoke and dust discharge. When the extended sealing component 23 is working, during the extended sealing process, the electromagnetic plate 232 is energized to generate a repulsive force with the same polarity as the magnetic block 235. The repulsive force pushes the guide post 234 to move and extend, and the guide post 234 drives the smoke sealing cloth 231 to unfold. When the smoke sealing cloth 231 is recycled, the electromagnetic plate 232 is energized and generates an attractive force with the magnetic block 235 of opposite polarity. The attractive force drives the guide post 234 to move and retract, and the guide post 234 drives the smoke sealing cloth 231 to be recycled. When the drive component 26 is working, the stepper motor 263 drives the drive gear 264 to rotate. The drive gear 264 drives the arc positioning frame 22 to rotate around the vertical rod 21 through the arc-shaped gear plate 262 and the L-shaped rod 261. During blasting, the arc-shaped spray pipe 271 and the linear spray pipe 272 can spray water mist to suppress dust at the same time. When the material conveyor belt 126 outputs slag through the flexible strip belt 242, the linear spray pipe 272 can suppress dust. Water pipe 274 can be connected to a water supply system installed on the trolley frame 10. After the electric control valve 273 and the water supply system are opened, water can flow into the arc spray pipe 271 and the linear spray pipe 272. When smoke and dust are discharged, the mobile smoke exhaust device 30 can perform fixed-point smoke exhaust. The lifting control component 31 drives the end of the first pipe 322 to move to the end of the robotic arm 11. At this time, the controller receives the smoke concentration information measured by the smoke concentration detector 331, and after analyzing the smoke concentration information, triggers the robotic arm 11 to move the end of the first pipe 322 to the area where the smoke concentration is higher than the set value. The fan 321 is turned on, and the high-concentration smoke can be directly discharged into the exhaust pipe 251 through the first pipe 322, the fan 321 and the second pipe 323. The first pipe, 322, is a telescopic folding pipe; When the lifting control component 31 is working, the self-locking motor 313 drives the winch 312 to rotate. The winch 312 drives the lifting ring 315 to move through the rope until the outer wall of the lifting ring 315 abuts against the arc-shaped limit plate 314. Then the self-locking motor 313 self-locks to complete the lifting and positioning work of the end of the first pipe 322.
