Description

Technical Field

[0001] The present invention relates to the field of plasma cutting, and particularly to a processing device for highway inspection robots. Background Art

[0002] During the processing of highway inspection robots, it is necessary to cut and process the base steel plate of the inspection robot. The existing patent (Publication No.: CN221389310U) proposes a plasma cutting machine, which includes an operation box. A plurality of sliding grooves are opened on both sides of the upper surface of the operation box. A moving base is slidably connected above the sliding grooves on the upper surface of the operation box. A hydraulic lift is fixedly connected inside the moving base, and the hydraulic lift penetrates to the outer surface of the moving base. The top of the hydraulic lift is fixedly connected with a fixed box. However, in this device, "a plurality of T-shaped grooves are opened on the upper surface of the operation board to fix the processed parts". The T-shaped grooves may be contaminated by the metal vapor generated during the cutting process after long-term operation, and regular cleaning operations are required. The manual cleaning operator needs to operate an additional cleaning machine for cleaning operations. The cleaning machine is relatively large in size, thus affecting the overall cleaning convenience and cleaning efficiency. Summary of the Invention

At the bottom of the worm support columns, there are worm installation platforms. The worm installation platforms are rotatably connected to the driving worm. The driven worm gear meshes with the driving worm. On the side of the worm installation platform, there is a worm motor groove. The worm driving motor is inserted and fixed inside the worm motor groove. The transmission shaft of the worm driving motor is fixedly connected to the driving worm.

[0006] The linkage self-cleaning device includes a drive plate adjusting hydraulic cylinder, a lower drive plate, an adjusting link, and a lower link mounting post. The lower drive plate is provided at the bottom of the main support frame. There are drive plate positioning grooves at the four corners of the lower drive plate. The positions of the drive plate positioning grooves correspond to the positions of the main support legs, and the drive plate positioning grooves are adapted to the main support legs. The drive plate positioning grooves are connected to the main support legs and slide outside the main support legs. The two sides of the main support frame perpendicular to the plane where the side shielding plate is located are fixedly connected to the drive plate adjusting hydraulic cylinder. One side of the lower drive plate facing the drive plate adjusting hydraulic cylinder has a hydraulic cylinder connection ear, and the bottom of the hydraulic rod of the drive plate adjusting hydraulic cylinder is fixedly connected to the hydraulic cylinder connection ear.

The link post bearing collar is connected to the link post bearing slide and slides outside the link post bearing slide.

[0007] Beneficial effects: 1. Through the movable design of the main bearing plate and the self-cleaning groove of the bearing plate in the present invention, when the operator needs to clean the main bearing plate and the self-cleaning groove of the bearing plate, the drive plate adjusting hydraulic cylinder is used to control all the main bearing plates and the self-cleaning grooves of the bearing plates to approach each other until they are in close contact. Through the adapted design of the main bearing plate and the self-cleaning groove of the bearing plate, the main bearing plate and the self-cleaning groove of the bearing plate are fully contacted, so that when the type-I support roller and the type-II support roller rotate, comprehensive friction is generated between the main bearing plate and the self-cleaning groove of the bearing plate, so that the main bearing plate is comprehensively cleaned. At the same time, the bottom of the self-cleaning groove of the bearing plate is designed with uneven grooves, so that the cleaning effect of the supporting surface of the self-cleaning groove of the bearing plate on the main bearing plate is better. Thus, the cleaning process can be automatically completed without the need for manual operation tools for cleaning. The processing and cleaning process of the highway inspection robot is convenient, fast and efficient.

[0008] 2. The main bearing plate in the present invention adopts a disc structure. When one side of the main bearing plate is contaminated, the main bearing plate can be rotated by a certain angle, so that the uncontaminated side of the main bearing plate faces upward, enabling the main bearing plate to continue to carry out normal supporting work, thereby extending the cleaning cycle of the main bearing plate and reducing the cleaning frequency. Moreover, each type-I support roller and type-II support roller is provided with a separate worm drive motor for driving, so that the operator can separately control the cleaning time of each type-I support roller and type-II support roller according to the contamination conditions of each type-I support roller and type-II support roller, avoiding power waste caused by too long cleaning time of some type-I support rollers and type-II support rollers, and making the cleaning process more energy-saving.

[0009] 3. The outer surface of the anti-fouling protective cover of the present invention is provided with relatively dense protective air holes, and each protective air hole is inclined upward. While assisting the plasma cutting head to dissipate heat, it also forms an air film on the outer surface of the anti-fouling protective cover during the cutting process, preventing the gas generated during the cutting process from adhering to the surface of the anti-fouling protective cover. The inclined upward design can also prevent the gas blown out from the protective air holes from interfering with the high-speed gas ejected by the plasma cutting head itself and affecting the cutting effect, ensuring the cutting stability and enhancing the heat dissipation, and strengthening the anti-fouling property during the cutting process in the highway inspection robot processing.

[0010] 4. The present invention performs air extraction operation through the air extraction pipe to press the bottom traction block against the upper part of the steel plate to be processed. The bottom traction block has a relatively large contact area with the steel plate to be processed, thus preventing local excessive stress on the surface of the steel plate to be processed and scratching during the process of the bottom traction block pulling the steel plate to be processed. At the same time, the connecting shaft of the traction bearing block is rotatably connected to the connecting plate of the traction bearing block, enabling the bearing block of the traction mechanism to automatically adjust its own angle according to the movement state of the steel plate to be processed during the process of pulling the steel plate to be processed, avoiding excessive bending force on the local part of the steel plate to be processed and causing bending, thereby ensuring the safety of loading the steel plate to be processed.

[0011] 5. The fine-tuning drive electric cylinder of the present invention can drive the side traction block to move away from or close to the traction mechanism bearing block, and the longitudinal displacement drive motor can drive the cutting head bearing block to move arbitrarily along the cutting head bearing slide, enabling the auxiliary loading mechanism to accurately place the steel plate to be processed at any position on the array group of type I support rollers and type II support rollers. During this process, little manual intervention is required. In the highway inspection robot processing, the positioning process of the steel plate to be processed is more labor-saving and accurate.

On the side of the worm mounting platform 42, there is a worm motor groove 43. The worm drive motor 44 is inserted and fixed inside the worm motor groove 43. The transmission shaft of the worm drive motor 44 is fixedly connected to the driving worm 45.

[0030] Embodiment 3: The linkage self-cleaning device 302 of the present invention includes a drive plate adjusting hydraulic cylinder 16, a lower drive plate 18, an adjusting link 48, and a lower link mounting post 49. The lower drive plate 18 is provided at the bottom of the main support frame 1. The four corners of the lower drive plate 18 have drive plate positioning grooves 17. The positions of the drive plate positioning grooves 17 correspond to the positions of the main support legs 2. The drive plate positioning grooves 17 are adapted to the main support legs 2. The drive plate positioning grooves 17 are connected to the main support legs 2 and slide on the outside of the main support legs 2. The two sides of the main support frame 1 perpendicular to the plane where the side shielding plate 74 is located are fixedly connected with the drive plate adjusting hydraulic cylinder 16. One side of the lower drive plate 18 facing the drive plate adjusting hydraulic cylinder 16 has a hydraulic cylinder connecting ear 19. The bottom of the hydraulic rod of the drive plate adjusting hydraulic cylinder 16 is fixedly connected to the hydraulic cylinder connecting ear 19. The two sides of the lower drive plate 18 facing the side shielding plate 74 have link post bearing slides 51. A plurality of lower link mounting posts 49 are provided at the top of the link post bearing slides 51. Each lower link mounting post 49 is located between two adjacent support roller bearing blocks 36. The two sides of the lower link mounting post 49 have lower link mounting ears 50.

The link post bearing collar 52 is connected to the link post bearing slide 51 and slides on the outside of the link post bearing slide 51.

[0031] Further, for an operation method of a processing device for a highway inspection robot, when slag removal operations need to be performed on the type-I support roller 20 and the type-II support roller 23, the drive plate adjusting hydraulic cylinder 16 drives the lower drive plate 18 to move downward, causing the lower link mounting post 49 to move downward. At the same time, the lower link mounting post 49 is pulled by the link structure composed of the lower link mounting ear 50, the adjusting link 48, and the upper link mounting ear 47, so that the lower link mounting post 49 and the support roller bearing block 36 approach each other, thereby causing the type-I support roller 20 and the type-II support roller 23 to approach each other. Until the type-I support roller 20 and the type-II support roller 23 are in full contact, the main bearing plate 21 is inserted into the bearing plate self-cleaning groove 22. Then, the worm drive motor 44 is started. The worm drive motor 44 drives the type-I support roller 20 and the type-II support roller 23 to rotate simultaneously through the cooperation between the driving worm 45 and the driven worm gear 40. Relying on the friction between the main bearing plate 21 and the bearing plate self-cleaning groove 22, the debris on the surface of the main bearing plate 21 is automatically removed.

[0032] It should be noted that through the movable design of the main bearing plate 21 and the self-cleaning groove 22 of the bearing plate, when the operator needs to clean the main bearing plate 21 and the self-cleaning groove 22 of the bearing plate, the hydraulic cylinder 16 is controlled by the driving plate to make all the main bearing plates 21 and the self-cleaning grooves 22 of the bearing plate approach each other until they are in close contact. Through the adapted design of the main bearing plate 21 and the self-cleaning groove 22 of the bearing plate, the main bearing plate 21 and the self-cleaning groove 22 of the bearing plate are in full contact, so that when the type I support roller 20 and the type II support roller 23 rotate, the main bearing plate 21 and the self-cleaning groove 22 of the bearing plate generate comprehensive friction, so that the main bearing plate 21 is comprehensively cleaned. At the same time, the bottom of the self-cleaning groove 22 of the bearing plate is designed with uneven grooves, so that the cleaning effect of the supporting surface of the self-cleaning groove 22 of the bearing plate on the main bearing plate 21 is better. Thus, the cleaning process can be automatically completed without manual operation tools for cleaning. The processing and cleaning process of the highway inspection robot is convenient, fast and efficient.

[0033] It should also be noted that the main bearing plate 21 adopts a disc structure. When one side of the main bearing plate 21 is contaminated, the main bearing plate 21 can be rotated by a certain angle, so that the uncontaminated side of the main bearing plate 21 faces upward, enabling the main bearing plate 21 to continue normal supporting work, thereby extending the cleaning cycle of the main bearing plate 21 and reducing the cleaning frequency. Moreover, each type I support roller 20 and type II support roller 23 is driven by a separate worm drive motor 44, so that the operator can separately control the cleaning time of each type I support roller 20 and type II support roller 23 according to the contamination situation of each type I support roller 20 and type II support roller 23, avoiding power waste caused by too long cleaning time of some type I support rollers 20 and type II support rollers 23, and making the cleaning process more energy-saving.

An extension plate positioning groove 25 is provided on the side surface of the internal lead screw installation groove 24. An extension plate 28 is provided on the side surface of the lead screw connection block 27. The extension plate positioning groove 25 is adapted to the extension plate 28. The extension plate positioning groove 25 is connected to the extension plate 28, and the extension plate 28 slides inside the extension plate positioning groove 25. A cutting head connection block 29 is provided on the side surface of the extension plate 28. The cutting head electric telescopic rod 30 is inserted and fixed inside the cutting head connection block 29. The bottom of the telescopic tube of the cutting head electric telescopic rod 30 is fixedly connected to the cutting head claw 31. The middle of the cutting head claw 31 is fixedly connected to the plasma cutting head 32. A cutting nozzle 33 is provided at the bottom of the plasma cutting head 32. The anti-fouling protective cover 34 is sleeved outside the cutting nozzle 33 and fixed.The outer surface of the anti-fouling protection cover 34 has protection air holes 341. Multiple groups of protection air holes 341 are evenly arranged around the anti-fouling protection cover 34. The inside of the anti-fouling protection cover 34 has a total air supply annular hole 342. The total air supply annular hole 342 is located above the array group of protection air holes 341.

The side of the total air supply annular hole 342 has an air supply pipe installation platform 343. The total air supply pipe 344 is inserted into the inside of the air supply pipe installation platform 343 and fixed.

[0035] Further, after the steel plate 9 to be processed is placed, the plasma cutting head 32 is started for plasma cutting operation. The longitudinal displacement driving motor 70 is used to control the longitudinal displacement driving gear 71 to move at the bottom of the displacement rack 68, so as to control the overall movement of the cutting head bearing block 11 along the cutting head bearing slide 64. The transverse displacement driving motor 13 is used to control the rotation of the transverse displacement driving lead screw 26, so as to control the lead screw connecting block 27 to slide inside the inner lead screw installation groove 24 along the cutting head bearing block 11. The cooperation of the longitudinal displacement driving motor 70 and the transverse displacement driving motor 13 enables the plasma cutting head 32 to perform cutting at different positions and can complete complex cutting paths. At the same time, during the cutting process of the plasma cutting head 32, the total air supply pipe 344 injects gas into the total air supply annular hole 342, so that all the protection air holes 341 eject gas synchronously, increasing the heat dissipation effect inside the plasma cutting head 32 and forming an air film on the side of the anti-fouling protection cover 34 to avoid the gas generated during the cutting process from adhering to the surface of the anti-fouling protection cover 34.

[0036] It should be noted that the outer surface of the anti-fouling protection cover 34 is provided with relatively dense protection air holes 341, and each protection air hole 341 is inclined upward. While assisting in the heat dissipation of the plasma cutting head 32, it also forms an air film on the outer surface of the anti-fouling protection cover 34 during the cutting process to avoid the gas generated during the cutting process from adhering to the surface of the anti-fouling protection cover 34. The inclined upward design can also prevent the gas blown out by the protection air holes 341 from interfering with the high-speed gas ejected by the plasma cutting head 32 itself and affecting the cutting effect. The road inspection robot processing strengthens the heat dissipation while ensuring the cutting stability and enhances the anti-fouling property during the cutting process.

[0037] Example 5: The auxiliary loading mechanism 5 of the present invention includes a traction electric cylinder 54, a traction mechanism bearing rod 55, a traction mechanism bearing block 56, a side traction block 60, and a fine-tuning drive electric cylinder 62. On the side of the cutting head bearing block 11 away from the plasma cutting head 32, there is a traction cylinder mounting platform 53. The traction electric cylinder 54 is inserted and fixed inside the traction cylinder mounting platform 53. The bottom of the telescopic tube of the traction electric cylinder 54 is fixedly connected to the traction mechanism bearing rod 55. On both sides of the traction mechanism bearing rod 55, there are traction bearing block connecting shafts 75. At the bottom of the traction bearing block connecting shafts 75, there is a traction mechanism bearing block 56. On the top of the traction mechanism bearing block 56, there is a traction bearing block connecting plate 57. The traction bearing block connecting plate 57 is rotatably connected to the traction bearing block connecting shaft 75. Inside the traction mechanism bearing block 56, there are a fine-tuning electric cylinder installation groove 59 and a side traction block positioning groove 58. The fine-tuning electric cylinder installation groove 59 is in the center position, and the side traction block positioning grooves 58 are distributed on both sides of the fine-tuning electric cylinder installation groove 59. On the side of the traction mechanism bearing block 56, there is a side traction block 60. On the side of the side traction block 60 facing the traction mechanism bearing block 56, there is a side traction block positioning post 61. The side traction block positioning post 61 is adapted to the side traction block positioning groove 58. The side traction block positioning post 61 is connected to the side traction block positioning groove 58, and the side traction block positioning post 61 slides inside the side traction block positioning groove 58. The fine-tuning drive electric cylinder 62 is inserted and fixed inside the fine-tuning electric cylinder installation groove 59. The telescopic tube of the fine-tuning drive electric cylinder 62 is fixedly connected to the side traction block 60. At the bottom of the side traction block 60, there is a bottom traction block 63. At the bottom of the bottom traction block 63, there is an air extraction port 76. On the side of the bottom traction block 63, there is an air extraction pipe 77. The air extraction pipe 77 is communicated with the internal space of the air extraction port 76. The end of the air extraction pipe 77 is connected to an air extraction device.

[0038] Further, when performing the auxiliary loading operation of the steel plate 9 to be processed, the operator places the steel plate 9 to be processed on one side of the main support frame 1. The cutting head bearing block 11 moves above the steel plate 9 to be processed. At this time, the telescopic tube of the traction electric cylinder 54 extends, and the bottom traction block 63 contacts the steel plate 9 to be processed. At this time, the air extraction device connected to the air extraction pipe 77 is started, and a negative pressure is generated inside the air extraction port 76. The bottom traction block 63 is tightly attached to 07. At this time, the cutting head bearing block 11 moves towards the middle of the main support frame 1, and the steel plate 9 to be processed is pulled onto the array group of the first-type support rollers 20 and the second-type support rollers 23 to complete the loading operation. After that, according to the processing requirements, the cutting head bearing block 11 pulls the steel plate 9 to be processed to the processing position, and cooperates with the fine-tuning drive electric cylinder 62 to drive the side traction block 60 to approach or move away from the traction mechanism bearing block 56, so as to complete the position fine-tuning operation of the steel plate 9 to be processed, and thus complete the positioning operation of the steel plate 9 to be processed.

[0039] It should be noted that, by performing the air extraction operation through the air extraction pipe 77, the bottom traction block 63 is pressed against the upper part of the steel plate 9 to be processed. The contact area between the bottom traction block 63 and the steel plate 9 to be processed is relatively large, thereby avoiding excessive local stress on the steel plate 9 to be processed during the process of the bottom traction block 63 pulling the steel plate 9 to be processed and scratching the surface. At the same time, the traction bearing block connecting shaft 75 is rotatably connected to the traction bearing block connecting plate 57, so that during the process of pulling the steel plate 9 to be processed, the traction mechanism bearing block 56 can automatically adjust its own angle according to the movement state of the steel plate 9 to be processed, avoiding excessive bending force on the local part of the steel plate 9 to be processed during the process of pulling the steel plate 9 to be processed and causing bending, thereby ensuring the safety of loading the steel plate 9 to be processed.

[0040] The present invention utilizes a stable support structure and cutting head control to maintain the stability of the cutting process, and at the same time combines anti-fouling protection and self-cleaning design. The synergistic effect jointly achieves precise cutting and neat cut edges, effectively preventing phenomena such as uneven cutting edges, burrs, cutting edge build-up, and slag hanging. The outer surface of the anti-fouling protection cover is provided with dense and inclined upward protection air holes. After the main air supply pipe injects gas into the main air supply annular hole, the protection air holes eject gas, forming an air film on the outer surface of the anti-fouling protection cover to avoid the attachment of gas generated during the cutting process. At the same time, the inclined upward design can prevent the ejected gas from interfering with the high-speed gas ejected by the plasma cutting head itself, ensuring the stability of the cutting arc, thereby reducing problems such as uneven cutting edges and burrs caused by gas interference. The gas ejected from the protection air holes can assist in dissipating heat from the plasma cutting head, avoiding the cutting head from overheating due to long-term operation and affecting the cutting accuracy and stability, and reducing the risk of cutting edge build-up and slag hanging. During the cutting process, its air extraction function can, to a certain extent, assist in removing metal vapor and fine residues near the cutting area, reducing the accumulation of residues at the cutting edge, and reducing the possibility of cutting edge build-up and slag hanging.

[0041] It should also be noted that the fine-tuning drive electric cylinder 62 can drive the side traction block 60 to move away from or close to the traction mechanism bearing block 56, and the longitudinal displacement drive motor 70 can drive the cutting head bearing block 11 to move arbitrarily along the cutting head bearing slide 64, so that the auxiliary loading mechanism 5 can accurately place the steel plate 9 to be processed at any position on the array group of the first-type support rollers 20 and the second-type support rollers 23. During this process, no large amount of manual intervention is required, making the positioning process of the steel plate 9 to be processed more labor-saving and accurate.

[0042] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be pointed out that for those of ordinary skill in the art in the technical field, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
