Description

Technical Field

[0001] The present invention relates to the field of lidar recognition, and specifically to a lidar recognition device for intelligent excavators. Background Art

[0002] An excavator is a heavy construction machinery mainly used in earthwork projects and mining operations. It has powerful excavation capabilities and flexible operating performance, and can complete various earthwork projects and mining tasks. The main working components of an excavator include an engine, a hydraulic system, a robotic arm, and a bucket. In addition to earth and rock excavation, excavators are also commonly used to clean the silt and sediment in rivers, canals, ports, and other water bodies to maintain the depth and width of waterways and ensure the smoothness of shipping and drainage. The design of the excavator's digging bucket and robotic arm enables it to perform effective excavation and handling operations in different environments. When carrying out dredging, the excavator can adjust the digging depth and angle to adapt to different working conditions.

[0003] During dredging operations, excavators are often equipped with lidar recognition devices to quickly and accurately identify the terrain and target excavation objects from the water body, thereby improving the dredging efficiency and work safety.

[0004] Although the installation of a lidar recognition device can assist in planning the dredging path and determining the quantity and location of sediments to be removed when the excavator is performing dredging operations, when the excavator is moving, it is likely to cause large splashes, resulting in the splashing of pollutants such as water or mud scale onto the surface of the lidar, which affects the working effect of the recognition device and leads to a decrease in the service life of the lidar. Therefore, an intelligent excavator lidar recognition device is proposed to address the above problems. Summary of the Invention

[0005] To make up for the deficiencies of the prior art and solve the problem that when the excavator is moving, it is likely to cause large splashes, resulting in the splashing of pollutants such as water or mud scale onto the surface of the lidar, which affects the working effect of the recognition device and leads to a decrease in the service life of the lidar, the present invention proposes an intelligent excavator lidar recognition device.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: An intelligent excavator lidar recognition device described in the present invention includes an excavator main body; a control cabin is fixedly installed at the top of the excavator main body, and an identification seat is fixedly installed at the top of the control cabin. A power mechanism and a steering rod are installed inside the identification seat. The bottom end of the steering rod is connected to the output end of the power mechanism. A rotating base is fixedly installed above the steering rod. A shock-absorbing component for reducing the wear of the lidar scanning device when the excavator main body travels is arranged at the bottom end of the rotating base. A lidar scanning device is fixedly installed at the top end of the rotating base. A blocking component for protecting the lidar scanning device during dredging operations is arranged on the periphery of the lidar scanning device;

[0007] The blocking component includes a blocking cover arranged on the periphery of the lidar scanning device. A lifting component is arranged at the bottom end of the blocking cover. A positioning component is arranged on the inner wall of the blocking cover. Blocking covers are symmetrically and slidably installed at the top end of the blocking cover. An opening component is arranged on one side of each blocking cover; By setting the blocking component, when the excavator main body moves, the blocking cover and the blocking covers cooperate to block the splashed water and pollutants, avoiding the problem that when the excavator is traveling, it is easy to cause large water splashes, so that water bodies or dirt and other pollutants splash onto the surface of the lidar, thus affecting the working effect of the recognition device and reducing the service life of the lidar, improving the working effect of the device and extending the service life of the device.

[0008] Preferably, the lifting component includes a lifting sliding disk arranged at the bottom end of the blocking cover. A lead screw is threadedly installed inside the lifting sliding disk. The lead screw is connected to the steering rod through a bearing. Guide rods are symmetrically installed on both sides of the lead screw. The bottom ends of the guide rods are fixedly installed on the inner wall of the identification seat. A first gear is fixedly installed at the bottom end of the lead screw. A second gear is meshed and installed on one side of the first gear. A motor is installed at the bottom end of the second gear. The motor is connected to an external power supply through a wire; By setting the lifting component, when the excavator main body is parked, the intelligent module arranged in the control cabin can send a signal to control the motor to start, so that the motor drives the blocking cover to move towards the direction close to the identification seat through the second gear, the first gear, the lead screw and the lifting sliding disk, thereby stopping the isolation of the lidar scanning device and enabling the lidar scanning device to perform scanning and recognition operations.

[0009] Preferably, the opening component includes a sliding plate disposed on one side of the barrier cover. The bottom ends of the sliding plates are fixedly installed with telescopic rods. The bottom ends of the telescopic rods are fixedly installed with first rotating seats. One ends of the first rotating seats are rotatably installed with connecting rods. The ends of the connecting rods away from the first rotating seats are rotatably installed with second rotating seats. The second rotating seats are fixedly installed on both sides of the barrier cover. By providing the opening component, when the barrier cover descends and stops isolating the lidar scanning device, the barrier cover drives the second rotating seat to move, so that the second rotating seat drives the barrier cover to separate from each other through the connecting rod, the first rotating seat, the telescopic rod and the sliding plate, avoiding the problem that when the barrier cover descends, the barrier cover abuts against the top of the lidar scanning device, resulting in movement interference, and improving the stability and reliability of the device.

[0010] Preferably, first guiding blocks are fixedly installed on both sides of the first rotating seat. The first guiding blocks are slidably installed on the inner walls of the first guiding grooves. The first guiding grooves are fixedly installed on the top end of the recognition seat, which can limit the moving track of the first rotating seat and make the movement of the first rotating seat smoother and more stable.

[0011] Preferably, second guiding blocks are symmetrically fixedly installed at the bottom ends of the sliding plates. The second guiding blocks are slidably installed on the inner walls of the second guiding grooves. The second guiding grooves are fixedly installed on the top end of the barrier cover, which can limit the moving tracks of the barrier cover and the sliding plate and make the movement of the barrier cover and the sliding plate smoother and more stable.

[0012] Preferably, the shock absorption component includes a buffer plate disposed at the bottom end of the rotating base. The buffer plate is fixedly installed at the top end of the steering rod. The buffer plate and the rotating base are connected by springs. The springs are evenly installed at the top end of the buffer plate. When the excavator body travels on a muddy road section, the elastic potential energy can be accumulated by the provided springs, thereby absorbing the vibration of the lidar scanning device. It avoids the problem that when the excavator body is performing dredging operations, the uneven road surface is likely to cause the excavator body to jolt, thereby affecting the lidar scanning device and resulting in unnecessary wear of the lidar scanning device, reducing the service life of the lidar scanning device. It reduces the vibration of the lidar scanning device when the excavator body is moving, thereby reducing the wear of the lidar scanning device and extending the service life of the lidar scanning device.

[0013] Preferably, the springs are all wound around the outer wall of the thick guide rod, the thick guide rods are all fixedly installed at the top end of the buffer plate, the inner walls of the thick guide rods are all slidably installed with thin guide rods, and the top ends of the thin guide rods are all fixedly installed at the bottom end of the rotating base; among them, the radius of the cross-section of the thick guide rod is larger, which can play a guiding and protecting role for the spring during elastic deformation of the spring. The radius of the cross-section of the thin guide rod is smaller, which can give the rotating base space to move and guide the vibration direction of the rotating base by sliding on the inner wall of the thick guide rod.

[0014] Preferably, the positioning assembly includes a connecting block arranged on the inner wall of the barrier cover. The maximum distance between the bottom end of the connecting block and the top end of the rotating base is equal to the maximum distance between the bottom end of the second rotating seat and the top end of the recognition seat; by setting the positioning assembly, when the lidar scanning device starts scanning and recognizing, the connecting block abuts against the top end of the rotating base, thereby squeezing the spring until the connecting block drives the rotating base to move and abut against the thick guide rod, making the position of the rotating base fixed and no longer shaking due to the spring, improving the scanning and recognition efficiency of the lidar scanning device.

[0015] Preferably, a positioning block is fixedly installed at the bottom end of one end of the connecting block, and the bottom ends of the positioning blocks all abut against the inner wall of the positioning groove. The positioning groove is opened at the top end of the rotating base; when the connecting block abuts against the rotating base, it can drive the positioning block to abut against the inner wall of the positioning groove, which can further improve the positioning efficiency of the positioning assembly. When the lidar scanning device performs scanning and recognition operations, the steering rod can drive the lidar scanning device to rotate through the buffer plate, thick guide rod, thin guide rod and rotating base, improving the recognition effect of the lidar scanning device.

[0016] Preferably, both sides of the top end of the positioning groove are set to be inclined and extend outwards; through the inclined part at the top end of the positioning groove, it makes it smoother for the positioning block to move into the positioning groove, avoiding the problem of movement interference caused by the positioning block abutting against the bottom end of the rotating base.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, by setting the barrier assembly, when the excavator main body moves, the barrier cover and the barrier lid cooperate to block the splashed water and pollutants, avoiding the problem that when the excavator is driving, it is easy to cause large water splashes, so that water bodies or dirt and other pollutants splash on the surface of the lidar, thereby affecting the working effect of the recognition device and reducing the service life of the lidar. It improves the working effect of the device and extends the service life of the device;

[0019] 2. In the present invention, by providing a shock-absorbing component, when the excavator main body travels on a muddy road section, elastic potential energy can be accumulated by the provided spring, thereby absorbing the vibration of the lidar scanning device. This avoids the problem that when the excavator main body is performing dredging operations, the uneven road surface is likely to cause the excavator main body to jolt, thereby affecting the lidar scanning device, resulting in unnecessary wear of the lidar scanning device and a decrease in the service life of the lidar scanning device. It reduces the vibration of the lidar scanning device when the excavator main body is traveling, thereby reducing the wear of the lidar scanning device and extending the service life of the lidar scanning device.

By setting the barrier component, when the main body 1 of the excavator moves, the barrier cover 7 and the barrier lids 8 cooperate to block the splashed water and pollutants, avoiding the problem that when the excavator travels, large water splashes are easily caused, so that water bodies or dirt and other pollutants splash on the surface of the lidar, thus affecting the working effect of the recognition device and reducing the service life of the lidar, improving the working effect of the device and prolonging the service life of the device.

[0033] Please refer to Figure 4As shown in the figure, the lifting assembly includes a lifting slide plate 9 arranged at the bottom end of the barrier cover 7. A lead screw 10 is threadedly installed inside the lifting slide plate 9. The lead screw 10 is connected to the steering rod 4 through a bearing. Guide rods 11 are symmetrically installed on both sides of the lead screw 10. The bottom ends of the guide rods 11 are fixedly installed on the inner wall of the identification seat 3. A first gear 12 is fixedly installed at the bottom end of the lead screw 10. A second gear 13 is meshed and installed on one side of the first gear 12. A motor 14 is installed at the bottom end of the second gear 13. The motor 14 is connected to an external power source through a wire. In addition, an intelligent module is provided in the control cabin 2, which can automatically detect whether the excavator main body 1 moves and automatically send a signal to control the motor 14 to start when the excavator main body 1 is parked. By setting the lifting assembly, when the excavator main body 1 is parked, a signal can be sent through the intelligent module provided in the control cabin 2 to control the motor 14 to start, so that the motor 14 drives the barrier cover 7 to move towards the direction close to the identification seat 3 through the second gear 13, the first gear 12, the lead screw 10 and the lifting slide plate 9, thereby stopping the isolation of the lidar scanning device 6, enabling the lidar scanning device 6 to perform scanning and identification operations. The model of the motor 14 is LW100.

[0034] Please refer to Figures 2 to 7 As shown in the figure, the opening assembly includes a slide plate 15 arranged on one side of the barrier cover 8. Telescopic rods 16 are fixedly installed at the bottom ends of the slide plate 15. First rotating seats 17 are fixedly installed at the bottom ends of the telescopic rods 16. One ends of the first rotating seats 17 are rotatably installed with connecting rods 18. The other ends of the connecting rods 18 away from the first rotating seats 17 are rotatably installed with second rotating seats 19. The second rotating seats 19 are fixedly installed on both sides of the barrier cover 7. By setting the opening assembly, when the barrier cover 7 descends and stops isolating the lidar scanning device 6, the barrier cover 7 drives the second rotating seat 19 to move, so that the second rotating seat 19 drives the barrier covers 8 to separate from each other through the connecting rod 18, the first rotating seat 17, the telescopic rod 16 and the slide plate 15, avoiding the problem that when the barrier cover 7 descends, the barrier cover 8 abuts against the top end of the lidar scanning device 6, thus causing movement interference, and improving the stability and reliability of the device.

[0035] In summary, through the cooperation of the lifting assembly and the opening assembly, when the excavator main body 1 is parked, the motor 14 can be started, so that the motor 14 drives the barrier cover 7 to move towards the direction close to the identification seat 3 through the second gear 13, the first gear 12, the lead screw 10 and the lifting slide plate 9. At the same time, the barrier cover 7 drives the barrier covers 8 to separate from each other through the second rotating seat 19, the connecting rod 18, the first rotating seat 17, the telescopic rod 16 and the slide plate 15, thereby stopping the isolation protection of the lidar scanning device 6 by the barrier cover 7 and the barrier covers 8, enabling the lidar scanning device 6 to scan and identify the working environment, and through cooperation with the intelligent module provided in the control cabin 2, it can be automatically started and closed, improving the working efficiency of the device and reducing the manual operation steps.

[0036] Please refer to Figures 2 to 5 and Figure 7 As shown, on both sides of the first rotating seat 17, first guiding blocks 20 are fixedly installed. The first guiding blocks 20 are all slidably installed on the inner wall of the first guiding groove 21. The first guiding grooves 21 are all fixedly installed at the top end of the recognition seat 3, which can limit the moving track of the first rotating seat 17, making the movement of the first rotating seat 17 smoother and more stable.

[0037] Please refer to Figures 5 to 7 As shown, at the bottom end of the sliding plate 15, second guiding blocks 22 are symmetrically and fixedly installed. The second guiding blocks 22 are all slidably installed on the inner wall of the second guiding groove 23. The second guiding grooves 23 are all fixedly installed at the top end of the barrier cover 7, which can limit the moving tracks of the barrier cover 8 and the sliding plate 15, making the movements of the barrier cover 8 and the sliding plate 15 smoother and more stable.

[0038] In summary, by providing the first guiding blocks 20, the first guiding grooves 21, the second guiding blocks 22 and the second guiding grooves 23, when the lifting assembly and the opening assembly operate, the movements of the first rotating seat 17 and the sliding plate 15 can be guided and limited, and the movements of the first rotating seat 17 and the sliding plate 15 can be made smoother, thereby making the lifting assembly and the opening assembly more stable and reliable.

[0039] Embodiment 2

[0040] Please refer to Figure 5 and Figure 7 As shown, compared with Embodiment 1, as another implementation manner of the present invention, the shock absorption assembly includes a buffer plate 24 provided at the bottom end of the rotating base 5. The buffer plate 24 is fixedly installed at the top end of the steering rod 4. The buffer plate 24 and the rotating base 5 are connected by springs 25. The springs 25 are evenly installed at the top end of the buffer plate 24. When the excavator main body 1 travels on a muddy road section, the elastic potential energy can be accumulated through the provided springs 25, thereby absorbing the vibration of the lidar scanning device 6, avoiding the problem that when the excavator main body 1 performs dredging operations, the uneven road surface is likely to cause the excavator main body 1 to jolt, thereby affecting the lidar scanning device 6 and causing unnecessary wear of the lidar scanning device 6, resulting in a decrease in the service life of the lidar scanning device 6. The vibration received by the lidar scanning device 6 when the excavator main body 1 travels is reduced, thereby reducing the wear of the lidar scanning device 6 and prolonging the service life of the lidar scanning device 6.

[0041] Please refer to Figure 7As shown, the springs 25 are all wound around the outer wall of the thick guide rod 26. The thick guide rods 26 are all fixedly installed at the top of the buffer plate 24. The inner walls of the thick guide rods 26 are all slidably installed with thin guide rods 27. The tops of the thin guide rods 27 are all fixedly installed at the bottom of the rotating base 5. Among them, the radius of the cross-section of the thick guide rod 26 is relatively large, which can guide and protect the spring 25 when the spring 25 undergoes elastic deformation. The radius of the cross-section of the thin guide rod 27 is relatively small, which can give the rotating base 5 space to move and guide the vibration direction of the rotating base 5 by sliding on the inner wall of the thick guide rod 26.

[0042] Please refer to Figures 5 to 7 As shown, the positioning component includes a connecting block 28 arranged on the inner wall of the barrier cover 7. The maximum distance between the bottom end of the connecting block 28 and the top end of the rotating base 5 is equal to the maximum distance between the bottom end of the second rotating seat 19 and the top end of the identification seat 3. By setting the positioning component, when the lidar scanning device 6 starts scanning and identifying, the connecting block 28 abuts against the top end of the rotating base 5, thereby squeezing the spring 25 until the connecting block 28 drives the rotating base 5 to move and abut against the thick guide rod 26, making the position of the rotating base 5 fixed and no longer shaking due to the spring 25, improving the scanning and identifying efficiency of the lidar scanning device 6.

[0043] In summary, through the cooperation of the lifting component and the positioning component, when the lifting component drives the barrier cover 7 to move, the connecting block 28 can be driven to move through the barrier cover 7, and the rotating base 5 can be squeezed through the connecting block 28, making the positions of the rotating base 5 and the lidar scanning device 6 quickly fixed and no longer shaking due to the spring 25, improving the working efficiency of the device. In addition, when the connecting block 28 abuts against the rotating base 5, the lifting component intelligently slows down the output power, making the operation of the positioning component more stable.

[0044] Please refer to Figures 5 to 7 As shown, positioning blocks 29 are fixedly installed at the bottom ends of one ends of the connecting blocks 28. The bottom ends of the positioning blocks 29 all abut against the inner walls of the positioning grooves 30. The positioning grooves 30 are opened at the top end of the rotating base 5. When the connecting block 28 abuts against the rotating base 5, the positioning blocks 29 can be driven to abut against the inner walls of the positioning grooves 30, which can further improve the positioning efficiency of the positioning component. When the lidar scanning device 6 performs scanning and identifying operations, the steering rod 4 can drive the lidar scanning device 6 to rotate through the buffer plate 24, the thick guide rod 26, the thin guide rod 27 and the rotating base 5, improving the identifying effect of the lidar scanning device 6.

[0045] Please refer to Figures 5 to 7As shown, both sides of the top end of the positioning groove 30 are arranged to extend outward in an inclined shape, which can make the movement of the positioning block 29 into the positioning groove 30 smoother when the connecting block 28 drives the positioning block 29 to move to the inner wall of the positioning groove 30 through the inclined part at the top end of the positioning groove 30, avoiding the problem of movement interference caused by the contact between the positioning block 29 and the bottom end of the rotating base 5.

[0046] Working principle: When the main body 1 of the excavator is transferred, the rough road surface is likely to cause the main body 1 of the excavator to jolt, so that the main body 1 of the excavator drives the buffer disc 24 to jolt through the control cabin 2 and the steering rod 4. The buffer disc 24 squeezes the spring 25, causing the spring 25 to undergo elastic deformation and accumulate elastic potential energy, thereby reducing the vibration impact of the main body 1 of the excavator on the rotating base 5.

[0047] When the main body 1 of the excavator moves to the target area and environmental recognition is required, after the intelligent module installed in the control cabin 2 detects that the main body 1 of the excavator has parked, it sends a signal to control the motor 14 to start. The motor 14 drives the second gear 13 to rotate, the second gear 13 drives the first gear 12 to rotate, the first gear 12 drives the lead screw 10 to rotate, so that the lead screw 10 drives the lifting slide plate 9 to move downward along the guide rod 11. The lifting slide plate 9 drives the barrier cover 7 to move, and at the same time the barrier cover 7 drives the second rotating seat 19 to move. The second rotating seat 19 drives the connecting rod 18 to rotate, so that the connecting rod 18 drives the first rotating seat 17 to move along the first guide groove 21. The first rotating seat 17 drives the telescopic rod 16 to move, the telescopic rod 16 drives the sliding plate 15 to move, the sliding plate 15 drives the barrier cover 8 to move, and the barrier cover 8 drives the second guide block 22 to move along the second guide groove 23, stopping the blocking of the lidar scanning device 6 from the environment. At the same time, the barrier cover 7 drives the connecting block 28 to move downward, the connecting block 28 drives the positioning block 29 to move, so that the positioning block 29 moves to the inner wall of the positioning groove 30. The positioning block 29 drives the positioning groove 30 to move, and the positioning groove 30 drives the rotating base 5 to move, so that the bottom end of the rotating base 5 abuts against the guide thick rod 26. At this time, the spring 25 undergoes elastic deformation and accumulates elastic potential energy, stopping the shaking and buffering. At this time, the buffer disc 24 and the lidar scanning device 6 can be controlled through the control cabin 2 to cooperate to scan and identify the environment.
