Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and in particular, to a dust suppression robot for tunnel blasting operations. Background Technology

[0002] During tunnel blasting operations, blasting operations instantly generate a large amount of dust and smoke, which not only seriously pollutes the working environment and harms the health of on-site construction personnel, but also obstructs vision and interferes with on-site condition observation and operation control. Therefore, rapid dust suppression after blasting is particularly crucial.

[0003] Currently, most traditional dust suppression equipment for cavern blasting has a single structure and function, making it difficult to move and flexibly transport to different blasting areas. Furthermore, existing dust suppression nozzles are mostly fixed in position, unable to be flexibly adjusted in spray direction, thus limiting the dust suppression coverage area. In addition, most equipment lacks integrated monitoring functions, preventing personnel from observing the device's operating status and on-site dust conditions in real time, requiring manual close-range inspection, which further increases the safety risks of personnel exposure to high-dust environments. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a dust suppression robot for tunnel blasting construction.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A dust suppression robot for tunnel blasting operations includes: a frame with a moving walking mechanism at the bottom and a detachable trailing plate at the tail, the trailing plate having rolling wheels at its bottom and supporting a water supply tank; a water pump assembly mounted on the frame, having an inlet pipe and an outlet pipe, the inlet pipe being connected to the water supply tank; a nozzle assembly mounted on the frame and capable of rotating and swinging relative to the frame, connected to the outlet pipe to obtain a water source; a cover connected to the frame, covering the water pump assembly and the nozzle assembly, with spray avoidance holes corresponding to the nozzle assembly, and a viewing hole in the cover; and a monitoring component mounted on the cover or the frame, aligned with the viewing hole.

[0006] Furthermore, the monitoring component includes: a transparent cover, mounted on the housing and covering the closed viewing hole; a mounting rod, connected to the edge of the transparent cover; a mounting plate, connected to the mounting rod; and a monitoring sensor, provided with a mounting base, the mounting base being mounted on the mounting plate.

[0007] Furthermore, the mounting plate can be adjusted to a fixed position along the axial direction of the mounting rod, and the mounting base can be adjusted to a fixed position along a first preset direction, wherein the first preset direction is perpendicular to the axial direction of the mounting rod.

[0008] Furthermore, the mounting base is provided with a connecting hole, the mounting plate is provided with a strip hole, the connecting hole is aligned with the strip hole and a second fastener is installed thereon, and the upper end of one of the strip holes extends to the upper edge of the mounting plate.

[0009] Furthermore, the transparent cover is installed on the inner wall of the housing, and the inner wall of the housing has a shielding cap above the transparent cover. The inner wall of the housing has a bottom shielding component detachably installed below the shielding cap. The inner sides of the shielding cap and the bottom shielding component are fitted with the outer peripheral edge of the mounting plate to form a dustproof and covered cavity to accommodate the monitoring sensor.

[0010] Furthermore, the rear of the frame is provided with a trailer block, the front end of the trailer plate is provided with a docking part, and the trailer block and the docking part are provided with corresponding holes and a positioning pin is inserted.

[0011] Furthermore, the mobile walking mechanism is a tracked mechanism.

[0012] Furthermore, the nozzle assembly includes: an adjustment drive mechanism having a rotatable rotating shaft; a nozzle mounting bracket connected to the rotating shaft so as to be driven to rotate by the rotating shaft; and a connecting pipe detachably mounted on the nozzle mounting bracket and able to be fixed after adjusting its position relative to the nozzle mounting bracket along its own axial direction. One end of the connecting pipe is connected to the water outlet head through a flexible hose, and the other end is detachably connected to a water outlet nozzle.

[0013] Furthermore, the frame is provided with a vertical rod, on which a vertical plate is fixedly installed. The adjustment drive mechanism is installed on the side of the vertical plate facing away from the nozzle mounting bracket. The rotating shaft passes through the vertical plate and is connected to the nozzle mounting bracket. A baffle plate is fixedly installed on the vertical rod, located below the vertical plate, with the upper end of the baffle plate in contact with the vertical plate.

[0014] Furthermore, the frame is provided with a limiting guide tube for the water inlet pipe connected to the water inlet head to pass through.

[0015] The present invention has the following beneficial effects: By incorporating a mobile walking mechanism at the bottom of the frame, the device possesses flexible mobility, enabling rapid transport to different blasting operation areas for convenient and flexible deployment. Simultaneously, the detachable trailing plate at the rear of the frame and its bottom rollers form a stable support and auxiliary walking structure. The trailing plate is specifically designed to carry the water supply tank, achieving a high degree of integration between the water system and the walking system, thus increasing the equipment's operating radius in complex cavern environments. The nozzle assembly is mounted on the frame and has the ability to rotate and swing relative to each other, avoiding a single spray direction. During operation, the nozzle assembly can adjust the spray angle and attitude by swinging, coordinating with the water pump assembly to form a dynamic spray fan, effectively expanding the dust suppression coverage area. This allows for rapid, multi-angle, and all-around suppression of dust dispersed after blasting, improving dust suppression efficiency. A cover is installed above the water pump assembly and nozzle assembly, not only protecting the internal mechanical components from dust and mechanical damage, extending the equipment's service life, but also ensuring smooth nozzle swing and spraying operations through water spray avoidance holes at the corresponding nozzle assembly locations. The monitoring components can capture real-time dust conditions and equipment operation status around the device through the viewing port. Personnel can obtain on-site information remotely without needing to approach the high-dust blasting site for manual inspection, effectively reducing the safety risks of personnel exposure to harmful environments and improving the safety of construction management.

[0023] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a dust suppression robot for tunnel blasting construction, comprising a frame 100, a water pump assembly 200, a nozzle assembly 300, and a cover 400.

[0024] The frame 100 has a moving walking mechanism 110 at the bottom and a detachable slide 120 at the rear. The slide 120 is equipped with rollers 121 at the bottom and is used to support the water supply tank.

[0025] The water pump assembly 200 is mounted on the frame 100 and is equipped with an inlet pipe head 210 and an outlet pipe head 220. The inlet pipe head 210 is used to connect to the water supply tank.

[0026] The nozzle assembly 300 is mounted on the frame 100 and can rotate and swing relative to the frame 100, and is connected to the water outlet head 220 to obtain a water source.

[0027] The cover 400 is connected to the frame 100. The cover 400 covers the water pump assembly 200 and the nozzle assembly 300. The nozzle assembly 300 is provided with a water spray avoidance hole 410, and the cover 400 is provided with a viewing hole 420.

[0028] The monitoring component 500 is mounted on the housing 400 and aligned with the viewing hole 420. Alternatively, in some other embodiments, the monitoring component 500 may be mounted on the rack 100.

[0029] A preferred embodiment of the dust suppression robot for tunnel blasting construction provided by this invention features a mobile walking mechanism 110 at the bottom of the frame 100, enabling the device to move flexibly and be quickly transported to different blasting operation areas for convenient and flexible deployment. Simultaneously, a detachable trailing plate 120 at the rear of the frame 100 and its bottom rolling wheels 121 form a stable support and auxiliary walking structure. The trailing plate 120 is specifically designed to carry a water supply tank, achieving a high degree of integration between the water system and the walking system, thus increasing the operating radius of the equipment in complex tunnel environments. The nozzle assembly 300 is mounted on the frame 100 and has the ability to rotate and swing relative to the surface, avoiding a single spray direction. During operation, the nozzle assembly 300 can adjust the spray angle and posture by swinging, coordinating with the water supply from the water pump assembly 200 to form a dynamic spray fan, effectively expanding the dust suppression coverage area. This allows for rapid, multi-angle, and all-around suppression of dust dispersed after blasting, improving dust suppression efficiency. A casing 400 is installed above the water pump assembly 200 and the nozzle assembly 300. This not only protects the internal mechanical components from dust and mechanical damage, extending the equipment's lifespan, but also ensures smooth nozzle movement and spraying operations by providing spray avoidance holes 410 at the corresponding nozzle assembly 300 locations. The monitoring component 500 can capture real-time dust conditions and equipment operation status around the device through the viewing hole 420. Personnel can obtain on-site information remotely without needing to approach the high-dust blasting site for manual inspection, effectively reducing the safety risks of personnel exposure to harmful environments and improving the safety of construction management.

[0030] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments of the present invention, the monitoring component 500 includes a transparent cover 510, a mounting rod 520, a mounting plate 530, and a monitoring sensor 540. The transparent cover 510 is mounted on the housing 400 and covers and seals the viewing hole 420; the mounting rod 520 is connected to the edge of the transparent cover 510; the mounting plate 530 is connected to the mounting rod 520; the monitoring sensor 540 has a mounting base 541, which is mounted on the mounting plate 530. The transparent cover 510, mounted on the housing 400 and sealing the viewing hole 420, prevents dust and explosion debris from entering the interior through the viewing hole 420, thus protecting the components behind it. The mounting rod 520 is connected to the edge of the transparent cover 510, providing a reliable mounting base for the mounting plate 530. It also allows the mounting plate 530 and the transparent cover 510 to form a spacing that allows the monitoring sensor 540 to be placed. The overall assembly structure is neat and can ensure that the monitoring sensor 540 can stably collect on-site images and working condition information through the viewing hole 420, thereby realizing real-time monitoring of the dust suppression site.

[0031] Reference Figure 3, Figure 4 and Figure 5 In some embodiments of the present invention, the mounting plate 530 can be adjusted and fixed along the axial direction of the mounting rod 520, and the mounting base 541 can be adjusted and fixed along a first preset direction, which is perpendicular to the axial direction of the mounting rod 520. The mounting plate 530 can slide along the axial direction of the mounting rod 520 to achieve flexible adjustment of the front and rear positions of the monitoring sensor 540; the mounting base 541 can move and be fixed along a first preset direction perpendicular to the axial direction of the mounting rod 520 to achieve adjustment of the vertical position of the monitoring sensor 540; relying on the bidirectional adjustable structure, the monitoring position of the monitoring sensor 540 can be adjusted according to the field of view requirements, the size of the monitoring sensor 540, and the position of the sensing part, thereby improving the monitoring flexibility and adaptability and better meeting the actual usage requirements of dust removal and working condition monitoring in underground caverns. The monitoring sensor 540 can be a camera, radar, or a device combining a camera and radar.

[0032] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments of the present invention, the mounting base 541 is provided with a connecting hole 542, and the mounting plate 530 is provided with a strip-shaped hole 531. The connecting hole 542 is aligned with the strip-shaped hole 531 and a second fastener is installed thereon. The second fastener can be a bolt or a nut. The strip-shaped hole 531 extends along a first preset direction, allowing the mounting base 541 to slide along the length of the strip-shaped hole 531 and then be fixed by the second fastener, thus achieving stepless fine adjustment of the monitoring sensor 540. During adjustment, only the second fastener needs to be loosened to slide and adjust the position, and tightening it will complete the fixation. The operation is convenient and the monitoring sensor 540 can be quickly adjusted to the optimal monitoring position. The upper end of the strip-shaped hole 531 extends to the upper edge of the mounting plate 530. The strip hole 531 is made into an open structure, allowing the wire harness of the monitoring sensor 540 to pass through the strip hole for wire management. The existing structure of the strip hole 531 is used for wire management, simplifying the structure. Since the strip hole is an open structure, the wire harness can be directly inserted into the opening of the strip hole 531 when installing it, without having to pass one end of the wire harness through the strip hole 531. This makes the operation simple during installation or removal.

[0033] In some embodiments of the present invention, the mounting plate 530 is provided with a clearance hole for the mounting rod 520 to pass through, and a fastening sleeve 550 is fixedly installed on the mounting plate 530 corresponding to the mounting rod 520. The fastening sleeve 550 is used to fixally connect with the mounting rod 520. By providing a clearance hole on the mounting plate 530 for the mounting rod 520 to pass through, the smoothness of the mounting plate 530 during axial sliding adjustment along the mounting rod 520 can be ensured, and interference from the mounting rod 520 on the movement of the mounting plate 530 can be avoided. At the same time, by providing a fastening sleeve 550 on the mounting plate 530, the connection and fixing structure between the mounting plate 530 and the mounting rod 520 is integrated into the body of the mounting plate 530, eliminating the need for additional complex fixing components. This simplifies the overall structure and allows the mounting plate 530 to be quickly and fixedly connected to the mounting rod 520 after the position is adjusted, improving the convenience of position adjustment and fixing while ensuring the compactness of the structure.

[0034] In a specific embodiment of the present invention, the fastening sleeve 550 is provided with a through hole for the mounting rod 520 to pass through, the clearance hole is aligned with the through hole, a notch is provided around the through hole, and mounting holes are provided on both sides of the notch. When the bolt passes through the mounting hole and the nut is tightened, the notch can be driven to shrink, thereby reducing the inner diameter of the through hole, so as to clamp and fix the mounting rod 520. The mounting plate 530 can be reliably fixed at any position in the axial direction of the mounting rod 520. When adjusting, the position can be slid and adjusted by loosening the fastener, which is simple to operate.

[0035] In a specific embodiment of the present invention, the transparent cover 510 includes a mounting frame 511 and a transparent plate 512. The mounting frame 511 is connected to the housing 400, and the transparent plate 512 is mounted on the mounting frame 511. When the transparent plate 512 becomes dirty, worn, or damaged, only the transparent plate 512 needs to be replaced, without replacing the entire transparent cover 510. A light-transmitting hole 513 is formed in the center of the mounting frame 511, which is aligned with the viewing hole 420. One end of the light-transmitting hole is provided with an inwardly protruding retaining ring 514. The transparent plate 512 is inserted into the light-transmitting hole and abuts against the retaining ring. When installing the transparent plate 512, the transparent plate 512 can be inserted into the light-transmitting hole and abut against the retaining ring. The retaining ring can limit and support the transparent plate 512. The size of the transparent plate 512 is adapted to the light-transmitting hole to prevent the transparent plate 512 from shifting during installation. The mounting frame 511 is mounted on the inner wall of the housing, and the mounting frame 511 and the housing are provided with corresponding holes for connection and fixation by fasteners. The retaining ring is located at the inner end of the light-transmitting hole. One side of the transparent plate 512 is attached to the inner side of the cover, and the other side abuts against the retaining ring, thereby fixing its position.

[0036] Reference Figure 11 and Figure 12In some other embodiments of the present invention, a transparent cover 510 is installed on the inner wall of the housing 400, and a shielding cap 600 is provided on the inner wall of the housing 400 above the transparent cover 510. A bottom shielding member 700 is detachably installed on the inner wall of the housing 400 below the shielding cap 600. The inner sides of the shielding cap 600 and the bottom shielding member 700 are fitted with the outer peripheral edge of the mounting plate 530 to form a dustproof and protective cavity to accommodate the monitoring sensor 540.

[0037] The bottom shield 700 features a detachable design. When maintenance or repair of the internal monitoring sensor 540 or adjustment structure is required, only the bottom shield 700 needs to be removed, eliminating the need to disassemble the entire housing 400, thus improving the ease of maintenance for internal components. By aligning the inner side of the shield cap 600 with the bottom shield 700 and the outer periphery of the mounting plate 530, a closed dustproof chamber is formed, completely enclosing the monitoring sensor 540 within this chamber. This effectively protects the monitoring sensor 540 from dust, reducing the intrusion of dust into the sensor and minimizing its impact on monitoring. This ensures the monitoring sensor 540 remains in a clean working environment, extending its lifespan and reducing the frequency of cleaning and maintenance. Furthermore, the upper edge of the transparent cover 510 is aligned with the shield cap 600; specifically, the upper edge of the mounting frame 511 is aligned with the shield cap 600. During installation, the cover cap 600 can assist in positioning the transparent cover 510, making it easier to align the holes and install the fasteners.

[0038] Reference Figure 1 and Figure 2 In some embodiments of the present invention, the frame 100 is provided with a trailer block 130 at the rear, and the trailer plate 120 is provided with a docking part 122 at the front end. The trailer block 130 and the docking part 122 are provided with corresponding holes and a positioning pin is inserted. The connection method is simple in structure and quick to assemble and disassemble, and the trailer plate 120 can be flexibly assembled or disassembled according to the usage requirements.

[0039] In a specific embodiment of the present invention, the mobile walking mechanism 110 is a tracked mechanism. By configuring the mobile walking mechanism 110 as a tracked mechanism, the track structure has a large ground contact area and strong grip, which can adapt to complex working conditions such as uneven road surfaces and numerous debris inside tunnels, thereby improving the stability and passability of the frame 100.

[0040] Reference Figure 8 , Figure 9 and Figure 10 In some embodiments of the present invention, the nozzle assembly 300 includes an adjustment drive mechanism 310, a nozzle mounting bracket 320, and a connecting pipe 330.

[0041] The adjustment drive mechanism 310 has a rotatable rotating shaft 311. The nozzle mounting bracket 320 is connected to the rotating shaft 311 and can be rotated by it. The connecting pipe 330 is detachably mounted on the nozzle mounting bracket 320 and can be adjusted and fixed relative to the nozzle mounting bracket 320 along its own axial direction. One end of the connecting pipe 330 is connected to the water outlet pipe 220 via a flexible hose, and the other end is detachably connected to the water outlet nozzle 331. By setting up the adjustment drive mechanism 310, the rotating shaft 311 drives the nozzle mounting bracket 320 to rotate, thereby driving the water outlet nozzle 331 to change its spray angle. This allows the nozzle to adjust its spray posture according to the complex dust distribution inside the cave, achieving all-around coverage spraying, significantly improving dust suppression efficiency, and effectively improving the working environment. The connecting pipe 330 is detachably installed on the nozzle mounting bracket 320 and can be adjusted and fixed relative to the nozzle mounting bracket 320 along its own axial direction. This allows the water outlet nozzle 331 to be adjusted in position as needed, enabling position adjustments during installation and improving the flexibility of on-site disassembly and adjustment. The use of a flexible hose to connect the water outlet pipe 220 and the connecting pipe 330, combined with the aforementioned rotational and axial adjustment structures, frees the entire water system from the constraints of rigid connections. When the adjustment drive mechanism 310 rotates the nozzle or the position of the connecting pipe 330 is manually adjusted, the flexible hose provides the necessary deformation allowance, ensuring the reliability of the water system connection and the smoothness of its operation.

[0042] Reference Figure 8 , Figure 9 and Figure 10 In some embodiments of the present invention, a vertical rod 140 is provided on the frame 100, and a vertical plate 150 is fixedly installed on the vertical rod 140. An adjustment drive mechanism 310 is installed on the side of the vertical plate 150 facing away from the nozzle mounting bracket 320. The nozzle mounting bracket 320 and the adjustment drive mechanism 310 are respectively located on both sides of the vertical plate 150. A rotating shaft 311 passes through the vertical plate 150 and is connected to the nozzle mounting bracket 320. A baffle plate 160 is fixedly installed on the vertical rod 140, located below the vertical plate 150, with its upper end in contact with the vertical plate 150. By placing the adjustment drive mechanism 310 on the back of the vertical plate 150, the driving part and the spraying part are physically isolated, resulting in a more reasonable and compact layout. The baffle plate 160 further blocks the area below the vertical plate 150, effectively preventing water mist from entering the interior of the adjustment drive mechanism 310, protecting driving components such as the motor and gearbox from corrosion, and extending the service life of the equipment.

[0043] Reference Figure 8 , Figure 9 and Figure 10In a further embodiment of the present invention, the nozzle mounting bracket 320 includes a connecting plate 321 and a fastening plate 322. The connecting plate 321 is connected to the end of the rotating shaft 311 by fasteners, and the fastening plate 322 is connected to the connecting plate 321 by fasteners. The fastening plate 322 has a through hole 323 for the connecting pipe 330 to pass through. The connecting pipe 330 can be adjusted in position along the through hole 323 and then connected and fixed to the fastening plate 322. The through hole 323 on the fastening plate 322 allows the connecting pipe 330 to be adjusted axially. After adjustment, it is fixed by connecting and fixing to the fastening plate 322, realizing the fine adjustment and locking of the spray position of the water nozzle 331. Specifically, the through hole 323 has a notch on its periphery, and the fastening plate 322 is equipped with a bolt that passes through the notch. The side walls on both sides of the notch have through holes. The bolt passes through the through holes and the nut is tightened to clamp and fix the connecting pipe 330, which facilitates the disassembly, assembly and locking of the connecting pipe 330 and improves the efficiency of on-site debugging and maintenance. A seated bearing 151 is installed on the side of the vertical plate 150 facing the nozzle mounting bracket 320. The seated bearing 151 is sleeved on the rotating shaft 311, which can effectively reduce rotational friction resistance and reduce drive load. Specifically, the adjusting drive mechanism 310, nozzle mounting bracket 320, and connecting pipe 330 are provided in two sets. The water outlet head 220 is connected to a water distribution pipe fitting 260, which has two water distribution outlets 261. The two water distribution outlets 261 are respectively connected to the two connecting pipes 330. The water flow from the water outlet head 220 is distributed to the two water distribution outlets 261 through the water distribution pipe fitting 260, realizing the simultaneous operation of dual nozzles. This can cover a wider cavern cross-section, improve the efficiency and coverage of dust suppression operations, and avoid the coverage blind spots caused by single-sided spraying.

[0044] Reference Figure 6 , Figure 7 and Figure 8In some embodiments of the present invention, the water pump assembly 200 includes a connecting seat 250 and a motor 230. The connecting seat 250 is fixedly mounted on the frame 100, and the motor 230 and the pump body 240 are fixedly mounted on the connecting seat 250. The connecting seat 250 serves as an intermediate connector, firmly fixing the motor 230 and the pump body 240 to the frame 100, achieving integrated installation of the motor 230 and the pump body 240. The connecting seat 250 has multiple mounting base plates 251 on its side, and the frame 100 has multiple raised mounting seats 180 corresponding to the mounting base plates 251. Both the raised mounting seats 180 and the corresponding mounting base plates 251 have holes for connection and fixation via fasteners. By raising the water pump assembly 200 as a whole using the raised mounting seats 180, more space is reserved below, facilitating wiring and the arrangement of other components, and reducing structural interference. A soft pad is sandwiched between the bottom of the raised mounting base 180 and the frame 100. The elastic deformation capacity of the soft pad effectively absorbs the vibration energy generated by the water pump assembly 200 during operation. This reduces the overall vibration amplitude and noise of the equipment, improves the stability of equipment operation, and also prevents fatigue damage to the frame structure caused by long-term vibration.

[0045] In a specific embodiment of the present invention, a limiting guide tube 170 is provided on the frame 100 to allow the water inlet pipe connected to the water inlet head 210 to pass through. This provides excellent limiting and guiding for the water inlet pipe, preventing it from swinging, tangling, or wearing out during operation. One end of the water inlet pipe is connected to the water supply tank, and the other end is connected to the water inlet head 210.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
