Description

Technical Field

[0001] The utility model relates to the field of anode carbon block cleaning equipment, in particular to a robot for cleaning carbon bowls of anode carbon blocks and a cleaning tool thereof. Background Technique

[0002] After the anode carbon block is baked and taken out of the furnace, a lot of filled coke powder will adhere to the surface of the carbon block. It must be cleaned by a cleaning unit to clean the filled coke powder before the next process can be carried out. The shape of the carbon block is a rectangular cube, the bottom surface is a plane, and a convex platform is provided on the top surface, and a plurality of carbon bowls are arranged on the convex platform. During the cleaning process of the carbon block, a large amount of agglomerated coke powder needs to be cleaned in the carbon bowl, and the carbon bowls of most carbon blocks are filled with coke powder. At present, the cleaning work mainly relies on manual labor or simple auxiliary tools for cleaning, the cleaning process is complicated, and the working environment is harsh.

[0003] A Chinese utility model patent document with the authorization announcement number CN217802512U discloses a cleaning tool for pre-baked anode carbon blocks. It drives a carbon bowl cleaning component through a pneumatic motor. The main shaft of the carbon bowl cleaning component rotates to drive the cleaning cutter head to rotate, so as to clean the inside of the carbon bowl. At the same time, the air outlet end of the pneumatic motor blows air into the carbon bowl through a pipeline, so as to realize the function of blowing away the attachments after cleaning. Thus, the automatic cleaning work of the carbon bowl is realized.

[0004] However, in actual use, the scraping and purging inside the carbon bowl are carried out synchronously. After the scraping operation is completed, the cutter head retracts upward. At this time, the attachments at the bottom of the carbon bowl cannot be effectively purged, and further dust cleaning work is still required. At the same time, the four sides of the convex platform on the top of the carbon block have variable diameter structures such as chamfers, rounded corners or concave edges. Only a single flat milling cutter cannot effectively scrape, and the scraping will cause a large dimensional deviation of the upper surface size of the carbon block. Subsequently, manual scraping and cleaning of these variable diameter positions are still required. At the same time, the attachments blown out from the carbon bowl will stay on the upper end surface of the carbon block, and workers still need to clean the surface of the carbon block subsequently, wasting labor.

[0042] In order to make the technical objectives, technical solutions and beneficial effects of the present utility model clearer, the following further describes the technical solutions of the present utility model in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model, that is, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0043] A specific embodiment of the anode carbon block carbon bowl cleaning robot involved in the present utility model is as Figures 1 to 9 shown. The anode carbon block carbon bowl cleaning robot includes a manipulator 1 and a cleaning tool 2 connected to the manipulator 1. Among them, the cleaning tool 2 includes a connecting seat 4. A six - axis force sensor 3 is connected between the connecting seat 4 and the manipulator 1. Specifically, the connecting seat 4 is a three - way barrel - shaped structure as a whole. There is a mounting bracket 42 on the side wall of the connecting seat 4, and the six - axis force sensor 3 is mounted on the mounting bracket 42. The overall main body of the surface cleaning robot uses a BXP210L robot, and the six - axis force sensor 3 is a sensor structure supporting the robot assembly. Its working principle and structure are the same as those of the prior art and will not be described in detail. Those skilled in the art can arbitrarily select other models of the manipulator 1 and the six - axis force sensor 3 according to actual needs.

[0044] A cleaning cutter head 5 and a cleaning head 6 are rotatably assembled on a connecting seat 4, and an air nozzle 7 is also fixed on the connecting seat 4. The cleaning cutter head 5, the cleaning head 6 and the air nozzle 7 are arranged at intervals around the circumferential side of the connecting seat 4. A driving mechanism for driving the cleaning cutter head 5 and the cleaning head 6 to rotate respectively is also provided on the connecting seat 4, and an air blowing pipeline connected to the air nozzle 7 is also provided. Preferably, for convenient control, the circumferential side of the connecting seat 4 has more than three connecting parts, and the cleaning cutter head 5, the cleaning head 6 and the air nozzle 7 are respectively connected to each connecting part.

[0045] As a preferred embodiment, in this embodiment, the connecting seat 4 is an overall three-way cylindrical structure, as Figure 3 and Figure 4 shown, it has three connecting shafts 41. The axes of two of the three connecting shafts 41 are the same and extend in opposite directions, and the axis of the other connecting shaft 41 is arranged perpendicular to the above-mentioned axis. The axis of the six-axis force sensor 3 is arranged perpendicular to the plane where the axes of the three connecting shafts 41 are located. Each connecting shaft 41 constitutes one of the connecting parts.

[0046] And in order to drive each connecting head, in this embodiment, the driving mechanism includes hydraulic motors 43 respectively connected to each connecting part. The output shafts of the respective hydraulic motors 43 are respectively connected to the cleaning cutter head 5 and the cleaning head 6 in one-to-one correspondence. As shown in the figure, inner holes are opened at the ends of each shaft, and the hydraulic motors 43 are fixedly stopped in the inner holes. The output shafts of the hydraulic motors 43 are the same as the axes of the corresponding connecting shafts 41 and extend outwards. A bushing 44 is fixed at the front end of the connecting shaft 41. A coupling 45 is rotatably assembled inside the bushing 44. The coupling 45 and the bushing 44 are coaxially rotatably assembled through bearings. One of the above-mentioned working heads is used to insert into the other end of the coupling 45, so as to realize the relative rotational assembly of the cleaning cutter head 5 and the connecting shaft 41. During actual driving, after the connecting seat 4 rotates the corresponding working head to a set angle, the hydraulic motor 43 rotates to drive the corresponding cleaning cutter head 5 or the cleaning head 6 to rotate, so as to realize the cleaning work on the surfaces of the carbon block and the carbon bowl.

[0047] And in order to install each working head, a locking sleeve 46 is also fixedly connected to the front end of the bushing 44. A locking hole is opened on the side wall of the locking sleeve 46, and a set screw 47 is provided in the locking hole, so that after the working head is inserted into the coupling 45, the anti-detachment of the connecting head can be realized. At the same time, a floating spring 48 is also arranged inside the coupling 45 and is mounted between the working head and the output shaft of the hydraulic motor 43, so as to realize a certain floating of the working head in the working direction, and avoid the problems that the scraper is impacted due to direct rigid contact with the carbon block and the cleaning accuracy cannot be accurately controlled.

[0048] There are two cleaning cutter heads 5 as described above, which are respectively connected to two of the connecting shafts 41. The cleaning head 6 is connected to another connecting shaft 41. The air nozzle 7 is connected to the side wall of the connecting seat 4. The installation positions of the four working heads are arranged in a cross direction, achieving a compact installation structure and effectively avoiding mutual interference.

[0049] The connection of the air nozzle 7 is as Figure 2 shown. On the installation frame 42 corresponding to the side wall of the connecting seat 4, there extends an installation hoop. A purging frame 8 is connected to the installation hoop. The purging frame 8 includes two L-shaped rods. The vertical side of the L-shaped rod is perpendicular to the plane where the axes of the three connecting shafts 41 are located, and the horizontal side extends horizontally. The above-mentioned air nozzle 7 is fixed on the horizontal side of the purging frame 8 and extends downward. The upper end of the air nozzle 7 is used to connect the blow pipe, so that the high-pressure gas is ejected downward through the air nozzle 7, effectively blowing off the attachments on the surface of the carbon bowl and the carbon block.

[0050] The structures of the two cleaning cutter heads 5 are as Figure 5 and Figure 6 shown. The cleaning cutter head 5 includes a cutter disc rotatably assembled on the corresponding connecting shaft 41. On the end face of the cutter disc, a plurality of blades are arranged at intervals around its rotation axis. The cutting edges of the blades protrude outward along the axis direction of the cutter disc. A sweeping brush is also connected to the cutter disc, and the protruding length of the sweeping brush is not less than the protruding length of the cutting edge.

[0051] Define the two cleaning cutter heads 5 as the first cleaning cutter head and the second cleaning cutter head respectively. The first cleaning cutter head includes a first cutter disc 51. On the front end face of the first cutter disc 51, a first cutter seat 52 is fixed. On the front end face of the first cutter seat 52, a plurality of first blades 53 are fixed. The first blades 53 are evenly distributed at intervals around the rotation axis of the cutter disc. The front end and side of the first blade 53 have a bottom cutting edge and a side cutting edge. The bottom cutting edge is used for scraping the bottom wall of the carbon bowl, and the side cutting edge is used for scraping the side wall of the carbon bowl, so as to achieve the complete cleaning of the carbon bowl. A perforation is formed on the circumferential side of the first cutter disc 51. A brush disc 55 is fixed behind the cutter disc. A plurality of first sweeping brushes 54 are fixed on the brush disc 55. The first sweeping brushes 54 extend forward through the perforation, and the front end of the first sweeping brush 54 protrudes beyond the front end of the first blade 53. During actual work, the first cutter disc 51 rotates, driving the first blades 53 and the first sweeping brushes 54 to rotate, so that when scraping the inner wall and bottom wall of the carbon bowl, the cleaning operation can be carried out synchronously.

[0052] The second cleaning cutter head includes a second cutter disc 56. On the front end face of the second cutter disc 56, a second cutter seat 57 is fixed. A plurality of cutter grooves are formed on the second cutter seat 57. A second blade 58 is fixed in each cutter groove. The second blades 58 are evenly distributed at intervals around the rotation axis of the cutter seat. At the same time, a second sweeping brush 59 is arranged between two adjacent second blades 58. The second sweeping brush 59 is arranged obliquely outward, and its sweeping contour is larger than the outer contour of the second blade 58. The second blade 58 has a side cutting edge and a bottom cutting edge.

[0053] The circumferential scraping outer contour of the above-mentioned first cleaning cutter head is smaller than that of the second cleaning cutter head, so as to adapt to carbon bowl types of different calibers and meet the universality of carbon bowl cleaning.

[0054] The structure of the cleaning head 6 is as Figure 7 shown. There are multiple cleaning heads 6, and each cleaning head 6 includes a bracket 61 and a brush 62 filled on the bracket 61. The cross-sectional shapes of the brackets 61 are different from each other. One of the cleaning heads 6 is selected and non-rotatably assembled with the output shaft of the corresponding hydraulic motor 43 on the connecting seat 4.

[0055] In this embodiment, three types of cleaning heads 6 are designed to adapt to cleaning operations at different types of stepped positions. The structure of the spherical cleaning head 6 is as Figure 7 shown, which includes a ball head and a brush 62 arranged on the ball head. The structure of the columnar cleaning head 6 is as Figure 8 shown, which includes a mounting post and a brush 62 densely arranged on the side wall and end face of the mounting post. In order to simplify the structure, the structure of the spherical cleaning head 6 can also be designed as Figure 9 shown, which forms a cage structure by connecting several arc-shaped ribs in series, and the brush 62 is arranged on the arc-shaped ribs.

[0056] During actual use, the manipulator 1 is used to adjust the angle of the connecting seat 4, and the cleaning cutter head 5 of the appropriate size is rotated to a position coaxial with the carbon bowl. Then the hydraulic motor 43 works, and the cleaning cutter head 5 extends downward into the carbon bowl. While scraping, the attachments are cleaned to prevent accumulation inside. After cleaning, the attachments in each carbon bowl are effectively blown out through the air nozzle 7. Finally, the appropriate cleaning head 6 is adjusted to effectively scrape the stepped position of the convex block on the upper end face of the carbon block. After that, the attachments are blown out through the air nozzle 7 again, and effective cleaning of the upper end of the carbon block and the inside of the carbon bowl can be achieved.

[0057] Of course, in other embodiments, the structure and principle of the cleaning cutter head 5 are not limited. Its quantity can be arbitrarily designed according to the actual type of carbon block. The connecting seat 4 can also be designed to have two connecting shafts 41, which are respectively connected to a cleaning cutter head 5 and a cleaning head 6, and the other cleaning cutter heads 5 are selectively connected to the corresponding connecting shafts 41.

[0058] For the specific embodiment of the cleaning tool 2 involved in the present utility model, its structure is the same as that of the cleaning tool 2 in the embodiment of the anode carbon block carbon bowl cleaning robot described above, and will not be described in detail.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Any equivalent replacement of the present invention and any modification or partial replacement that does not depart from the spirit and scope of the present invention shall be covered by the scope of protection of the claims of the present invention.
