Description

Technical Field

[0001] The present invention relates to the technical field of manhole cover production, and in particular to a manhole cover production and processing device and an operating method thereof. Background Art

[0002] Manhole covers, also known as road manhole covers, are typically used to cover well openings on roads or sidewalks to prevent people or objects from falling in. Manhole covers come in different sizes and sizes depending on the environment and needs. Round manhole covers are more common, while square covers are also used on residential sidewalks and in parks.

[0003] For example, a surface polishing device for producing ductile iron manhole covers with publication number CN114952552A is provided, which comprises a mounting plate, a cavity, a first threaded rod, a first motor, a first threaded cylinder, a guide plate, a guide port, a movable box, a manhole cover body, a mounting frame, a support frame, a second threaded rod, a second threaded cylinder, a support plate, a support port, a movable 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, the side wall of the manhole cover can be automatically polished, without requiring the operator to disassemble and assemble the manhole cover multiple times, thereby reducing the time spent on disassembling and assembling the manhole cover and improving the working efficiency of the manhole cover polishing. However, in actual use, when polishing the top and bottom of the manhole cover, the polishing process is not very convenient. When grinding and polishing the outer wall, two steps are required. The top and side walls of the manhole cover cannot be ground at the same time. When grinding the outer wall of a square manhole cover, the polishing device cannot grind the outer wall of the square manhole cover after rotation due to the limitation of the square. It is not suitable for grinding manhole covers of different shapes. When grinding a square manhole cover, since the rotation range keeps changing, if a spring is directly used for adaptive grinding, when the square manhole cover is rotated to tilt, the grinding device will increase the contact force with the manhole cover under the action of the spring reaction force, which can easily cause excessive grinding force, making it easy to produce scratches during grinding, which will affect the adhesion of paint in the later spraying process. There are certain usage defects.

[0004] Therefore, we propose a manhole cover production and processing equipment and an operating method thereof to solve the problems raised above. Summary of the Invention

[0029] By adopting the above technical solution, the up and down movement of the support rod can drive the movable frame to move left and right.

[0030] An operating method of a manhole cover production and processing equipment, the specific operating method is as follows:

[0031] Step 1:

[0032] When the manhole cover is polished, the manhole cover is fixed by the fixing assembly, 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 is driven to slide on the fixed frame, so that the polishing disc can be driven to move downward and fit the manhole cover. During the downward movement of the movable plate, the movable frame moves, and the movable frame can slide on the fixed rod and stretch the telescopic spring. The movement of the movable frame causes the polishing roller to move, and then the movable frame moves in the opposite direction, so that the polishing roller first fits the outer wall of the manhole cover, and then the movable frame continues to move to make the roller fit the outer wall of the manhole cover, so that the movable rod slides on the movable frame to cause the stretching spring to deform, so that the polishing roller always contacts the outer wall of the manhole cover, and then the driving motor is started to drive the polishing disc to rotate, and the rotating motor is started to drive the polishing roller to rotate, so that the rotating shaft rotates, and then the first pulley and the second pulley can be used. The connection drives the rotating rod to rotate, and then the meshing of the rotating gear and the inner gear ring causes the mounting plate to rotate, so that the spherical rod slides in the annular groove, so that the grinding roller can rotate in a circular motion to grind the outer wall of the manhole cover, and the roller always abuts against the side wall of the manhole cover. The top of the manhole cover can be polished while the grinding disc rotates. When grinding a square manhole cover, the roller always fits against the side wall of the manhole cover, and the abutment between the roller and the manhole cover during the circumferential rotation of the grinding roller can push the movable frame to move. The abutment force between the grinding roller and the manhole cover does not change, so that when grinding the manhole cover, excessive grinding force is avoided during the grinding process of the outer wall of the square manhole cover, causing over-grinding. The top and outer wall of the manhole cover can be polished at the same time, thereby improving the grinding work efficiency and being able to grind manhole covers of different shapes and sizes, thereby improving practicality.

[0033] Step 2:

[0034] To fix the manhole cover, place it on the placement plate, then start the electric push rod to drive the cross to move down. The movement of the cross can drive the connecting rod to rotate. After the connecting rod rotates, the movable 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 two sets of rubber plates can fix the manhole cover and ensure that the manhole cover is in the center of the workbench, which is convenient for fixing the manhole cover and can prevent the manhole cover from deflecting, thereby improving practicality.

[0035] Step 3:

[0036] When the manhole cover is fixed, 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 down. During the downward movement of the mounting plate, the support rod is driven down, and the top of the guide groove on the movable plate is located 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 down. Then, as the support rod gradually moves down, the movable frame can be pushed to move through the cooperation of the guide groove and the column block. Then, as the column block disengages 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 resets and moves 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 as the mounting plate is moved upward, and the movable frame can be reset as the mounting plate is moved upward. 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.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows: the manhole cover production and processing equipment and the operating 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 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;

[0038] 1. When grinding the manhole cover, the manhole cover is fixed by the fixing assembly, 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 is driven to slide on the fixed frame, so that the grinding disc can be driven to move downward and fit the manhole cover. During the downward movement of the movable plate, the movable frame moves, and the movable frame can slide on the fixed rod and stretch the telescopic spring. The movement of the movable frame causes the grinding roller to move, and then the movable frame moves in the opposite direction, so that the grinding roller first fits the outer wall of the manhole cover, and then the movable frame continues to move to make the roller fit the outer wall of the manhole cover, so that the movable rod slides on the movable frame to deform the stretching spring, so that the grinding roller always contacts the outer wall of the manhole cover, and 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, and then the first pulley and the second pulley can be used to The connection of the wheel drives the rotating rod to rotate, and then the mounting plate is rotated by meshing the rotating gear with the inner gear ring, so that the spherical rod slides in the annular groove, so that the grinding roller can rotate in a circular motion to grind the outer wall of the manhole cover, and the roller always abuts against the side wall of the manhole cover. The top of the manhole cover can be polished while the grinding disc rotates. When grinding a square manhole cover, the roller always fits against the side wall of the manhole cover. The abutment between the roller and the manhole cover during the circumferential rotation of the grinding roller can push the movable frame to move, and the abutment force between the grinding roller and the manhole cover will not change, so that when grinding the manhole cover, excessive grinding force is avoided during the grinding of the outer wall of the square manhole cover, resulting in over-grinding. The top and outer wall of the manhole cover can be polished at the same time, thereby improving the grinding work efficiency and being able to grind manhole covers of different shapes and sizes, thereby improving practicality.

[0039] 2. To fix the manhole cover, place it on the placement plate, then start the electric push rod to drive the cross to move down. The movement of the cross can drive the connecting rod to rotate. After the connecting rod rotates, the movable 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 two sets of rubber plates can fix the manhole cover and ensure that the manhole cover is in the center of the workbench, which is convenient for fixing the manhole cover and can prevent the manhole cover from deflecting, thereby improving practicality.

[0040] 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 located 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 leaves 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. , so that after the column block leaves the guide groove, the movable frame resets and moves so that the grinding roller fits against the outer wall of the manhole cover, and at this time the movable plate will not affect the circumferential rotation of the support rod and the movable frame, and 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 up. 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 as the mounting plate is moved up, and the movable frame can be reset as the mounting plate is moved up. At this time, the manhole cover is removed, and the downward movement of the mounting plate can make the grinding roller move, which is convenient for the grinding roller to fit against the outer wall of the manhole cover, and convenient for resetting the grinding roller after grinding, thereby improving practicality.

[0068] The guide assembly 4 includes a J-shaped frame 401 fixedly mounted on one side of the bottom of the right movable frame 304, and the outer side of the J-shaped frame 401 is slidably connected to the limiting frame 402, and the limiting frame 402 is fixedly connected to the workbench 1. At the same time, the J-shaped frame 401 is slidably connected to the fixed frame 102, and the inner side of the J-shaped frame 401 is slidably connected to the limiting rod 403, and one end of the limiting rod 403 is fixedly connected to the fixed frame 102;

[0069] A movable plate 404 is fixedly installed on one end of the J-shaped frame 401 away from the movable frame 304, and a positioning rod 405 is fixedly installed on the side of the movable plate 404 close to the fixed frame 102, and the positioning rod 405 is slidably connected to the fixed frame 102. At the same time, a guide groove 406 is provided on the front side of the movable plate 404, and a support rod 407 is fixedly installed on the side of the movable frame 217 close to the movable plate 404, and a column block 408 is fixedly installed on one side of the support rod 407, and the column block 408 is slidably connected to the guide groove 406.

[0070] Example 3: Figures 1-4 、 Figure 6 and Figure 8-Figure 9As shown, when the manhole cover is fixed, the right movable frame 304 can drive the J-shaped frame 401 to move when it moves. After the J-shaped frame 401 moves, it can drive the movable plate 404 to move. After the manhole cover is fixed, the movable plate 404 stops moving, and then the mounting plate 201 is moved downward. During the downward movement of the mounting plate 201, the support rod 407 is driven downward. The top of the guide groove 406 on the movable plate 404 is located in a trumpet 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 movable frame 217 can be pushed to move through the cooperation of the guide groove 406 and the column block 408. Then, as the column block 408 disengages from the guide groove 406, the movable frame 217 is reset and moved, and the displacement of the column block 408 in the guide groove 406 is much greater than the maximum displacement of the movable frame 304 After the grinding is completed, the column block 408 is aligned with the bottom end of the guide groove 406, and then the mounting plate 201 is moved up. A slope is provided on one side of the bottom opening of the guide groove 406. Even if the column block 408 is not aligned with the guide groove 406, the column block 408 can enter the guide groove 406 as the mounting plate 201 is moved up, and the movable frame 217 can be reset as the mounting plate 201 is moved up. At this time, the manhole cover is removed, and the downward movement of the mounting plate 201 can move the grinding roller 221, which facilitates the grinding roller 221 to fit the outer wall of the manhole cover and facilitates the reset of the grinding roller 221 after grinding, thereby improving practicality.

[0071] Working principle: When using the manhole cover production and processing equipment, first, according to Figures 1-9As shown, when the manhole cover is being polished, the manhole cover is fixed by the fixing assembly 3, and 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 and fit into the manhole cover. During the downward movement of the movable plate 104, the movable frame 217 is moved, and the movable frame 217 can slide on the fixed rod 216 and stretch the telescopic spring 218. The movement of the movable frame 217 causes the grinding roller 221 to move, and then the movable frame 217 is moved in the opposite direction, so that the grinding roller 221 first fits into the outer wall of the manhole cover, and then the movable frame 217 continues to move so that the roller 225 fits into the outer wall of the manhole cover, so that the movable rod 222 slides on the movable frame 217, causing the stretching spring 223 to deform, so that the grinding roller 221 always abuts against the outer wall of the manhole cover, and 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, and then the rotating rod 208 can be driven to rotate by the connection between the first pulley 207 and the second pulley 209. Then, the mounting plate 201 is rotated by the engagement of the rotating gear 210 with the inner gear ring 211, so that the spherical rod 202 slides in the annular groove 203, so that the grinding roller 221 can rotate in a circular manner to grind the outer wall of the manhole cover, and the roller 225 always abuts against the side wall of the manhole cover. The grinding disc 212 can grind the top of the manhole cover while rotating. When grinding a square manhole cover, the roller 225 always fits against the side wall of the manhole cover. During the circumferential rotation of the grinding roller 221, the abutment between the roller 225 and the manhole cover can push the movable frame 217 to move, and the abutment force between the grinding roller 221 and the manhole cover does not change.

[0072] When fixing the manhole cover, the manhole cover is placed on the placement plate 302, and then the electric push rod 306 is started 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, the movable frame 304 can be pulled to slide on the support block 303, so that the two sets of rubber plates 305 can move away from each other at the same time. The two sets of rubber plates 305 can fix the manhole cover and ensure that the manhole cover is in the center of the workbench 1, which is convenient for fixing the manhole cover and can avoid the manhole cover from deflecting, thereby improving practicality. When the manhole cover is fixed, the right side movable frame 304 can drive the J-shaped frame 401 to move when it moves, and the J-shaped frame 401 can drive the movable plate 404 to move after it moves. After the manhole cover is fixed, the movable plate 404 stops moving, and then the mounting plate 201 moves down. During the downward movement of the mounting plate 201, the support rod 407 is driven downward. The top of the guide groove 406 on the movable plate 404 is located in a trumpet shape. Even if the column block 408 is not aligned with the guide groove 406, the column block 408 can also enter the guide groove 406 after the support rod 407 moves down. Then, as the support rod 407 gradually moves down , the cooperation between the guide groove 406 and the column block 408 can push the movable frame 217 to move, and then as the column block 408 leaves the guide groove 406, the movable frame 217 is reset and moved, and the movement displacement of the column block 408 in the guide groove 406 is much greater than the longest movement distance of the movable frame 304, so that after the column block 408 leaves the guide groove 406, the movable frame 217 is reset and moved so that the grinding roller 221 is in contact with the outer wall of the manhole cover, and at this time the movable plate 404 will not affect the circumferential rotation of the support rod 407 and the movable frame 217, and after the grinding is completed, the column block 408 and the guide groove are The bottom end of 406 is aligned, and then the mounting plate 201 is moved upward. A slope is set on one side of the bottom opening of the guide groove 406. Even if the column block 408 is not aligned with the guide groove 406, the column block 408 can enter the guide groove 406 as the mounting plate 201 is moved upward. The movable frame 217 can be reset as the mounting plate 201 is moved upward. At this time, the manhole cover is removed, and the downward movement of the mounting plate 201 can move the grinding roller 221, which is convenient for the grinding roller 221 to fit with the outer wall of the manhole cover, and convenient for resetting the grinding roller 221 after grinding, thereby improving practicality.
