Description

Technical Field

[0001] The present invention relates to the technical field of manhole cover production, and specifically to a manhole cover production and processing device and its operation method. Background Technique

[0002] A manhole cover, also known as a road manhole cover, is usually used to cover the wellhead on a road or sidewalk to prevent people or objects from falling in. According to different usage environments and requirements, the specifications and models of manhole covers also vary. Among them, circular manhole covers are more common in actual use, and square manhole covers are also used on sidewalks in communities, parks, etc.

[0003] For example, a surface polishing treatment device for the production of ductile iron manhole covers with the publication number CN114952552A. By setting an installation plate, a cavity, a first threaded rod, a first motor, a first threaded barrel, a guide plate, a guide port, a moving box, a manhole cover body, an installation frame, a support frame, a second threaded rod, a second threaded barrel, a support plate, a support port, a moving plate, a first electric push rod, a first polishing device, a third motor, a bent plate, a second electric push rod, and a second polishing device, after polishing the upper surface of the manhole cover, it can automatically polish the side wall of the manhole cover, eliminating the need for operators to disassemble and assemble the manhole cover multiple times, reducing the time consumed for disassembling and assembling the manhole cover, and improving the working efficiency of manhole cover polishing. However, in actual use, when polishing the top and outer side walls of the manhole cover, two steps are still required to complete, and the top and side walls of the manhole cover cannot be polished simultaneously. Moreover, when polishing the outer side wall of a square manhole cover, due to the limitation of the square shape after rotation, the polishing device cannot polish the outer side wall of the square manhole cover, and it is not applicable to polishing manhole covers of different shapes. Also, when polishing a square manhole cover, due to the continuously changing rotation range, if a spring is directly used to adapt to the polishing, when the square manhole cover rotates to an inclined position, the contact force between the polishing device and the manhole cover under the reaction force of the spring becomes larger, which is likely to cause excessive polishing force, resulting in scratches during polishing, and affecting the adhesion of paint in the later spraying process, having certain usage defects.

[0004] Therefore, we propose a manhole cover production and processing device and its operation method to solve the problems raised above. Summary of the Invention

[0022] By adopting the above technical solution, the up-and-down movement of the supporting rod can drive the left-and-right movement of the movable frame.

[0023] An operation method of a manhole cover production and processing device is as follows: Step 1: When grinding and processing the manhole cover, the manhole cover is fixed by the fixing component, and then the electric telescopic rod is started to drive the movable plate to move downward. During the downward movement of the movable plate, the guide rod slides on the fixed frame, so that the grinding disc can be driven to move downward and fit with the manhole cover. During the downward movement of the movable plate, the movable frame moves. The movable frame can slide on the fixed rod and stretch the telescopic spring. The movement of the movable frame makes the grinding roller move. Then the movable frame moves in the reverse direction, so that the grinding roller first fits with the outer side wall of the manhole cover. Then the movable frame continues to move so that the roller fits with the outer side wall of the manhole cover. The movable rod slides on the movable frame to cause the stretching spring to deform, so that the grinding roller always abuts against the outer side wall of the manhole cover. Then the driving motor is started to drive the grinding disc to rotate, and the rotating motor is started to drive the grinding roller to rotate, so that the rotating shaft rotates. Then the rotating rod can be driven to rotate through the connection of the first belt pulley and the second belt pulley. Then the installation plate rotates through the meshing of the rotating gear and the internal gear ring, so that the spherical rod slides in the annular groove, so that the grinding roller can rotate circumferentially to grind the outer side wall of the manhole cover, and the roller always abuts against the side wall of the manhole cover. While the grinding disc rotates, the top of the manhole cover can be ground. When grinding a square manhole cover, the roller always fits with the side wall of the manhole cover. During the circumferential rotation of the grinding roller, the abutment between the roller and the manhole cover can push the movable frame to move. The abutting force between the grinding roller and the manhole cover does not change, so that when grinding and processing the manhole cover, it is avoided that the grinding force is too large during the grinding of the outer side wall of the square manhole cover, resulting in over-grinding. The top and the outer side wall of the manhole cover can be ground at the same time, improving the grinding work efficiency, and manhole covers of different shapes and sizes can be ground, improving the practicability; Step 2: To fix the manhole cover, place the manhole cover on the placement plate, then start the electric push rod to drive the cross to move down, and the movement of the cross can drive the connecting rod to rotate. After the connecting rod rotates, the moving frame can be pulled to slide on the support block, so that the two sets of rubber plates can move away from each other at the same time. The manhole cover can be fixed by the two sets of rubber plates, and it can be ensured that the manhole cover is in the center of the workbench, which is convenient for fixing the manhole cover and can avoid the manhole cover from being offset, thereby improving practicality; Step 3: When fixing the manhole cover, the right movable frame can drive the J-shaped frame to move when it moves, and the J-shaped frame can drive the movable plate to move after it moves. After the manhole cover is fixed, the movable plate stops moving, and then the mounting plate is moved downward. During the downward movement of the mounting plate, the support rod is driven downward. The top of the guide groove on the movable plate is in a trumpet shape. Even if the column block is not aligned with the guide groove, the column block can enter the guide groove after the support rod moves downward. Then, as the support rod gradually moves downward, the movable frame can be pushed to move through the cooperation of the guide groove and the column block. Then, as the column block is separated from the guide groove, the movable frame is reset and moved, and the displacement of the column block in the guide groove is much greater than the longest moving distance of the movable frame. After the column block leaves the guide groove, the movable frame is reset and moved so that the grinding roller fits the outer wall of the manhole cover, and the movable plate will not affect the circumferential rotation of the support rod and the movable frame at this time. After the grinding is completed, the column block is aligned with the bottom end of the guide groove, and then the mounting plate is moved upward. A slope is provided on one side of the bottom opening of the guide groove. Even if the column block is not aligned with the guide groove, the column block can enter the guide groove with the upward movement of the mounting plate, and the movable frame can be reset with the upward movement of the mounting plate. At this time, the manhole cover is removed, and the downward movement of the mounting plate can move the grinding roller, which is convenient for the grinding roller to fit the outer wall of the manhole cover and convenient for resetting the grinding roller after grinding, thereby improving practicality. Compared with the prior art, the beneficial effects of the present invention are as follows: the manhole cover production and processing equipment and the operation method thereof can avoid excessive grinding caused by excessive grinding force during the grinding process of the outer wall of the square manhole cover, and can grind the top and the outer wall of the manhole cover at the same time, thereby improving the grinding work efficiency, and can grind manhole covers of different shapes and sizes, thereby improving practicality; 1. When grinding and processing the manhole cover, the manhole cover is fixed by the fixing component. Then, the electric telescopic rod is started to drive the movable plate to move downward. During the downward movement of the movable plate, the guide rod is driven to slide on the fixed frame, so that the grinding disc can be driven to move downward and fit with the manhole cover. During the downward movement of the movable plate, the movable frame moves. The movable frame can slide on the fixed rod and stretch the telescopic spring. The movement of the movable frame makes the grinding roller move. Then, the movable frame moves in the reverse direction, so that the grinding roller first fits with the outer side wall of the manhole cover. Then, the movable frame continues to move so that the roller fits with the outer side wall of the manhole cover, and the movable rod slides on the movable frame to deform the tension spring, so that the grinding roller always abuts against the outer side wall of the manhole cover. Then, the driving motor is started to drive the grinding disc to rotate, and the rotating motor is started to drive the grinding roller to rotate, so that the rotating shaft rotates. Then, the rotating rod can be driven to rotate through the connection of the first belt pulley and the second belt pulley. Then, the mounting plate rotates through the meshing of the rotating gear and the internal gear ring, so that the spherical rod slides in the annular groove, and the grinding roller can rotate circumferentially to grind the outer side wall of the manhole cover. And the roller always abuts against the side wall of the manhole cover. While the grinding disc rotates, it can grind the top of the manhole cover. When grinding a square manhole cover, the roller always fits with the side wall of the manhole cover. During the circumferential rotation of the grinding roller, the movement of the movable frame can be promoted through the abutment of the roller and the manhole cover. The abutting force between the grinding roller and the manhole cover will not change, so that when grinding and processing the manhole cover, it can be avoided that the grinding force is too large during the grinding of the outer side wall of the square manhole cover, resulting in over-grinding. The top and the outer side wall of the manhole cover can be ground at the same time, improving the working efficiency of grinding, and manhole covers of different shapes and sizes can be ground, improving the practicability; 2. When fixing the manhole cover, the manhole cover is placed on the placing plate. Then, the electric push rod is started to drive the cross to move downward. Through the movement of the cross, the connecting rod can be driven to rotate. After the connecting rod rotates, the movable frame can be pulled to slide on the support block, so that the two rubber plates can move away from each other at the same time. The manhole cover can be fixed by the two rubber plates, and it can be ensured that the manhole cover is at the center of the workbench, which is convenient for fixing the manhole cover and can avoid the offset of the manhole cover, improving the practicability; 3. When fixing the manhole cover, the right moving frame can drive the J-shaped frame to move when it moves. After the J-shaped frame moves, it can drive the moving plate to move. After the manhole cover is fixed, the moving plate stops moving. Then, the mounting plate moves downward. During the downward movement of the mounting plate, the support rod moves downward. The top of the guiding groove on the moving plate is in a flared shape. Even if the column block is not aligned with the guiding groove, the column block can enter the guiding groove after the support rod moves downward. Then, as the support rod gradually moves downward, the cooperation between the guiding groove and the column block can push the movable frame to move. Then, as the column block disengages from the guiding groove, the movable frame moves back. And the moving displacement of the column block in the guiding groove is much larger than the longest moving distance of the moving frame, so that after the column block leaves the guiding groove, the movable frame moves back to make the grinding roller fit with the outer sidewall of the manhole cover. And at this time, the moving plate will not affect the circumferential rotation of the support rod and the movable frame. After the grinding is completed, the column block is aligned with the bottom end of the guiding groove. Then, the mounting plate moves upward. One side of the bottom opening of the guiding groove is provided with a slope. Even if the column block is not aligned with the guiding groove, as the mounting plate moves upward, the column block can also enter the guiding groove. As the mounting plate moves upward, the movable frame can be reset. At this time, the manhole cover is removed. Furthermore, the downward movement of the mounting plate can make the grinding roller move, which is convenient for the grinding roller to fit with the outer sidewall of the manhole cover and convenient for resetting the grinding roller after grinding, improving the practicability.

A positioning rod 405 is fixedly installed on the side of the moving plate 404 close to the fixing frame 102. The positioning rod 405 is slidably connected with the fixing frame 102. A guiding groove 406 is formed on the front of the moving plate 404. A supporting rod 407 is fixedly installed on the side of the movable frame 217 close to the moving plate 404. A column block 408 is fixedly installed on one side of the supporting rod 407. The column block 408 is slidably connected with the guiding groove 406.

[0032] Embodiment 3: As Figures 1 - 4 、 Figure 6 and Figures 8 - 9As shown, when fixing the manhole cover, the right moving frame 304 can drive the J-shaped frame 401 to move when moving. After the J-shaped frame 401 moves, it can drive the moving plate 404 to move. After the manhole cover is fixed, the moving plate 404 stops moving. Then, the mounting plate 201 moves downward. During the downward movement of the mounting plate 201, the support rod 407 is driven to move downward. The top of the guide groove 406 on the moving plate 404 is in a flared shape. Even if the column block 408 is not aligned with the guide groove 406, the column block 408 can enter the guide groove 406 after the support rod 407 moves downward. Then, as the support rod 407 gradually moves downward, the cooperation between the guide groove 406 and the column block 408 can push the movable frame 217 to move. Then, as the column block 408 disengages from the guide groove 406, the movable frame 217 moves back to its original position. And the moving displacement of the column block 408 in the guide groove 406 is much larger than the longest moving distance of the moving frame 304, so that after the column block 408 leaves the guide groove 406, the movable frame 217 moves back to its original position, making the grinding roller 221 fit against the outer wall of the manhole cover. And at this time, the moving plate 404 does not affect the circumferential rotation of the support rod 407 and the movable frame 217. After grinding, the column block 408 is aligned with the bottom end of the guide groove 406. Then, the mounting plate 201 moves upward. The bottom opening side of the guide groove 406 is provided with a slope. Even if the column block 408 is not aligned with the guide groove 406, as the mounting plate 201 moves upward, the column block 408 can also enter the guide groove 406. As the mounting plate 201 moves upward, the movable frame 217 can be reset. At this time, the manhole cover is removed. Furthermore, the downward movement of the mounting plate 201 can make the grinding roller 221 move, facilitating the grinding roller 221 to fit against the outer wall of the manhole cover and facilitating the reset of the grinding roller 221 after grinding, improving the practicability.

[0033] Working principle: When using this manhole cover production and processing equipment, first, according to Figures 1 - 9As shown, when polishing the manhole cover, the manhole cover is fixed by the fixing component 3. Then, the electric telescopic rod 103 is started to drive the movable plate 104 to move downward. During the downward movement of the movable plate 104, the guide rod 105 is driven to slide on the fixing frame 102, so that the polishing disc 212 can be driven to move downward and fit with the manhole cover. During the downward movement of the movable plate 104, the movable frame 217 moves. The movable frame 217 can slide on the fixed rod 216 and stretch the telescopic spring 218. The movement of the movable frame 217 makes the polishing roller 221 move. Then, the movable frame 217 moves in the reverse direction, so that the polishing roller 221 first fits with the outer side wall of the manhole cover. Then, the movable frame 217 continues to move so that the roller 225 fits with the outer side wall of the manhole cover, making the movable rod 222 slide on the movable frame 217 and causing the tension spring 223 to deform, so that the polishing roller 221 always abuts against the outer side wall of the manhole cover. Then, the drive motor 205 is started to drive the polishing disc 212 to rotate, and the rotating motor 220 is started to drive the polishing roller 221 to rotate, making the rotating shaft 206 rotate. Then, the connecting rod 208 can be driven to rotate through the connection between the first belt pulley 207 and the second belt pulley 209. Then, the mounting plate 201 is rotated through the meshing of the rotating gear 210 and the internal gear ring 211, making the spherical rod 202 slide in the annular groove 203, so that the polishing roller 221 can rotate circumferentially to polish the outer side wall of the manhole cover, and the roller 225 always abuts against the side wall of the manhole cover. While the polishing disc 212 rotates, it can polish the top of the manhole cover. When polishing a square manhole cover, the roller 225 always fits with the side wall of the manhole cover. During the circumferential rotation of the polishing roller 221, the movement of the movable frame 217 can be promoted through the abutment between the roller 225 and the manhole cover, and the abutting force between the polishing roller 221 and the manhole cover will not change; When fixing the manhole cover, place the manhole cover on the placing plate 302, and then start the electric push rod 306 to drive the cross 307 to move downward. The movement of the cross 307 can drive the connecting rod 310 to rotate. After the connecting rod 310 rotates, it can pull the moving frame 304 to slide on the support block 303, so that the two rubber plates 305 can move away from each other at the same time. The two rubber plates 305 can fix the manhole cover, and can ensure that the manhole cover is at the center of the workbench 1, which is convenient for fixing the manhole cover and can prevent the manhole cover from shifting, improving the practicability. When fixing the manhole cover, when the right moving frame 304 moves, it can drive the J-shaped frame 401 to move. After the J-shaped frame 401 moves, it can drive the moving plate 404 to move. After the manhole cover is fixed, the moving plate 404 stops moving. Then, the mounting plate 201 moves downward. During the downward movement of the mounting plate 201, the support rod 407 moves downward. The top of the guide groove 406 on the moving plate 404 is trumpet-shaped. Even if the column block 408 is not aligned with the guide groove 406, the column block 408 can enter the guide groove 406 after the support rod 407 moves downward. Then, as the support rod 407 gradually moves downward, the cooperation between the guide groove 406 and the column block 408 can push the movable frame 217 to move. Then, as the column block 408 disengages from the guide groove 406, the movable frame 217 moves back to its original position. And the moving displacement of the column block 408 in the guide groove 406 is much larger than the longest moving distance of the moving frame 304, so that after the column block 408 leaves the guide groove 406, the movable frame 217 moves back to its original position, making the grinding roller 221 fit against the outer wall of the manhole cover. And at this time, the moving plate 404 will not affect the circumferential rotation of the support rod 407 and the movable frame 217. After grinding, the column block 408 is aligned with the bottom end of the guide groove 406. Then, the mounting plate 201 moves upward. The bottom opening side of the guide groove 406 is provided with a slope. Even if the column block 408 is not aligned with the guide groove 406, as the mounting plate 201 moves upward, the column block 408 can also enter the guide groove 406. As the mounting plate 201 moves upward, the movable frame 217 can be reset. At this time, the manhole cover is removed. Furthermore, the downward movement of the mounting plate 201 can make the grinding roller 221 move, which is convenient for the grinding roller 221 to fit against the outer wall of the manhole cover and convenient for resetting the grinding roller 221 after grinding, improving the practicability.

10. An operating method of a manhole cover production and processing device, using a manhole cover production and processing device as described in claim 9, characterized in that, The specific operation method is as follows: Step 1: When grinding the manhole cover, the manhole cover is fixed by the fixing component (3). Then, the electric telescopic rod (103) is started to drive the movable plate (104) to move downward. During the downward movement of the movable plate (104), the guide rod (105) is driven to slide on the fixed frame (102), so that the grinding disc (212) can be driven to move downward to fit with the manhole cover. During the downward movement of the movable plate (104), the movable frame (217) moves. The movable frame (217) can slide on the fixed rod (216) and stretch the telescopic spring (218). The movement of the movable frame (217) makes the grinding roller (221) move. Then, the movable frame (217) moves in the reverse direction, so that the grinding roller (221) first fits with the outer side wall of the manhole cover. Then, the movable frame (217) continues to move so that the roller (225) fits with the outer side wall of the manhole cover. The movable rod (222) slides on the movable frame (217) to make the tension spring (223) deformed, so that the grinding roller (221) always abuts against the outer side wall of the manhole cover. Then, the driving motor (205) is started to drive the grinding disc (212) to rotate, and the rotating motor (220) is started to drive the grinding roller (221) to rotate, so that the rotating shaft (206) rotates. Then, the rotating rod (208) can be driven to rotate through the connection of the first belt pulley (207) and the second belt pulley (209). Then, through the meshing of the rotating gear (210) and the internal gear ring (211), the mounting plate (201) rotates, so that the spherical rod (202) slides in the annular groove (203), so that the grinding roller (221) can rotate circumferentially; Step 2: When fixing the manhole cover, place the manhole cover on the placement plate (302), and then start the electric push rod (306) to drive the cross (307) to move downward. The movement of the cross (307) can drive the connecting rod (310) to rotate. After the connecting rod (310) rotates, it can pull the moving frame (304) to slide on the support block (303), so that the two rubber plates (305) can move away from each other at the same time. The two rubber plates (305) can fix the manhole cover and ensure that the manhole cover is at the center of the workbench (1). Step 3: When fixing the manhole cover, the movement of the right moving frame (304) can drive the J-shaped frame (401) to move. After the J-shaped frame (401) moves, it can drive the moving plate (404) to move. After the manhole cover is fixed, the moving plate (404) stops moving. Then, the mounting plate (201) moves downward. During the downward movement of the mounting plate (201), the support rod (407) moves downward. Then, as the support rod (407) gradually moves downward, the cooperation between the guide groove (406) and the column block (408) can push the movable frame (217) to move. Then, as the column block (408) disengages from the guide groove (406), the movable frame (217) moves back. And the moving displacement of the column block (408) in the guide groove (406) is much larger than the longest moving distance of the moving frame (304), so that after the column block (408) leaves the guide groove (406), the movable frame (217) moves back to make the grinding roller (221) fit against the outer wall of the manhole cover. At this time, the moving plate (404) will not affect the circular rotation of the support rod (407) and the movable frame (217). After grinding, align the column block (408) with the bottom end of the guide groove (406). Then, move the mounting plate (201) upward. As the mounting plate (201) moves upward, the movable frame (217) can be reset. At this time, remove the manhole cover.
