Description

Technical Field

[0001] This invention relates to the field of crane arc welding technology, specifically to automated crane welding equipment based on arc welding. Background Technology

[0002] A crane is a multi-action lifting machine that uses a hook or other lifting device to suspend heavy objects and vertically lift and horizontally move them within a certain range. It is also called a hoist and belongs to material handling machinery. The metal structure of a crane (such as the main beam, boom, tower, and outriggers) is the core that bears the heavy objects. Welding is the main way to connect these structural components into a whole. Welding quality defects (such as cracks, incomplete penetration, and porosity) may lead to insufficient structural strength and cause safety accidents such as fracture and collapse. Therefore, welding is regarded as a "lifeline" level process in crane manufacturing and must meet strict requirements for strength, toughness, fatigue performance, and dimensional accuracy. Arc welding is suitable for repair, small batch or complex bevel welding and is mostly used for auxiliary welds or on-site repairs of cranes.

[0003] Because cranes are generally quite tall, the large amount of fumes generated during automated welding can easily affect the observation of the welding position. Therefore, we propose an automated welding equipment for cranes based on arc welding. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an automated welding equipment for cranes based on electric arc welding, including a circular chassis. An electric roller is rotatably connected to the bottom of the circular chassis via a rotating bolt. A vertical electric slide rail is fixedly connected to the top of the circular chassis. A frame-shaped sleeve plate is fitted and slidably connected to the outer side of the vertical electric slide rail. External connecting rods are fixedly connected to all four sides of the frame-shaped sleeve plate. An annular electric slide rail is fixedly connected to the end of the external connecting rods away from the frame-shaped sleeve plate. A top-mounted annular plate is rotatably connected to the top of the annular electric slide rail. An electric robotic arm is fixedly connected to the top of the top-mounted annular plate. An arc welder is fixedly connected to one end of the electric robotic arm. A fumigation device is fixedly connected to the top of the top-mounted annular plate. A cleaning device is fixedly connected to the outer side of the annular electric slide rail. An auxiliary support device is fixedly connected to the bottom of the annular electric slide rail.

[0005] The fumigation device includes an annular shell. A high-pressure air pump is connected to the inner side of the annular shell. The high-pressure air pump sprays purified gas onto the vertical electric slide rail to blow away dust from the track groove, preventing welding slag and dust from adhering to the track groove after long-term use and affecting its use. Dust filter holes are opened on the outer side of the annular shell. By opening multiple dust filter holes on the outer side of the annular shell, the tiny welding slag and dust in the flue gas are filtered to prevent the tiny welding slag and dust in the flue gas from being sucked into the annular shell and accumulating for a long time, causing blockage and affecting the ventilation effect.

[0006] The electric rollers are provided in multiple ways and are distributed at the bottom of the circular chassis. The cleaning devices are provided in multiple ways and are distributed on the outside of the annular electric slide rail. The bottom of the auxiliary support device is fixedly connected to the top of the circular chassis.

[0007] The top of the annular shell is provided with a top opening annular hole, and a U-shaped slide rod is slidably connected to the inner wall of the top opening annular hole. An annular cover plate is fixedly connected to the top of the U-shaped slide rod. The annular filter element can be directly removed through the annular cover plate and the U-shaped slide rod for easy cleaning and replacement. This prevents the annular filter element from becoming less effective and unusable after prolonged contact with flue gas. An annular filter element is fixedly connected to the bottom of the annular cover plate. By setting the annular filter element inside the U-shaped slide rod, the flue gas with particulate matter removed is further purified. This prevents the flue gas from being poorly purified and from rapidly spreading to the surroundings under the propulsion of the high-pressure air pump, which would affect the welding process.

[0008] The bottom of the annular shell is fixedly connected to the top of the top ring plate, and the inner side of the U-shaped slide rod is fixedly connected to the outer side of the annular filter element. Multiple U-shaped slide rods are provided, and multiple U-shaped slide rods are distributed at the bottom of the annular cover plate.

[0009] Furthermore, the cleaning device includes a bottom corner plate, the top of which is fixedly connected to a rotary spring. A rotatable, resetting strip-shaped sleeve is provided between the bottom corner plate and the top circular plate to facilitate the rotation adjustment of the electric robotic arm without affecting it. This prevents the top ring plate from contacting the strip-shaped sleeve and hindering further rotation when adjusting the circumferential position of the electric robotic arm. The top of the rotary spring is fixedly connected to the strip-shaped sleeve. The bottom of the arc-shaped scraper is fixedly positioned to the top of the strip-shaped sleeve to stabilize the shape of the arc-shaped scraper, preventing it from being affected by external forces when sliding against the outer surface of the annular shell, thus ensuring close contact and improving the cleaning effect. The top of the strip-shaped sleeve is fixedly connected to the arc-shaped scraper, which scrapes the rotating outer surface of the annular shell. To prevent the filter holes from becoming clogged with welding slag and dust after prolonged filtration, thus affecting ventilation, a top circular plate is rotatably connected to the top of the strip-shaped sleeve rod via a bearing. A fixed through rod is fixedly connected to the bottom of the top circular plate. The fixed through rod, placed between the bottom corner plate and the top circular plate, limits the elastic connection of the strip-shaped sleeve rod, preventing it from tilting or shifting due to the rotation spring when pushed by the electric robotic arm, thus affecting its use. One side of the bottom corner plate is fixedly connected to the outer side of the annular electric slide rail. Multiple bottom corner plates are provided and distributed on the outer side of the annular electric slide rail. The bottom of the fixed through rod passes through the strip-shaped sleeve rod and is rotatably connected to it. The bottom of the fixed through rod is fixedly connected to the top of the bottom corner plate.

[0010] Furthermore, the auxiliary support device includes a first concave plate, with a first inner rod fixedly connected to the inner side of the first concave plate. A medium-sized sleeve plate is sleeved on the outer side of the first inner rod and rotatably connected via a bearing. A first return spring is fixedly connected to both sides of the medium-sized sleeve plate near the first concave plate, and a second return spring is fixedly connected to both sides of the medium-sized sleeve plate away from the first concave plate. A second concave plate is fixedly connected to the end of the second return spring away from the medium-sized sleeve plate. A second inner rod is fixedly connected to the inner side of the second concave plate, and a third inner rod is fixedly connected to the inner side of the second concave plate. A convex sleeve plate is fitted on the outer side and rotatably connected via bearings. By setting the convex sleeve plate and intermediate sleeve plate within the first and second concave plates, the convex sleeve plate and intermediate sleeve plate can only rotate to a vertical position at most. This prevents the convex sleeve plate and intermediate sleeve plate from folding outwards when fully extended, affecting usability. The foldable convex sleeve plate and intermediate sleeve plate between the annular electric slide rail and the circular base ensure that the bottom of the annular electric slide rail is always a certain distance from one end of the circular base. This prevents a large amount of accumulated impurities from adhering to the top surface of the circular base when the annular electric slide rail moves to contact the top surface of the circular base. The use of the annular electric slide rail is affected by the fact that both sides of the convex sleeve plate are fixedly connected with a return spring three. By setting return spring one, return spring two, and return spring three on both sides of the medium sleeve plate and the convex sleeve plate respectively, the medium sleeve plate and the convex sleeve plate are always in an unfolded trend to provide bottom support for the bottom of the annular electric slide rail. This prevents the heavy weight of the annular electric slide rail from affecting the driving effect of the vertical electric slide rail over a long period of time when too many parts are set on it. The two sides of the convex sleeve plate away from the medium sleeve plate are rotatably connected to fixed corner blocks through rotating bolts. Multiple first inner rods are provided, and multiple first inner rods are provided. The rods are distributed on the inner side of the first concave plate. The end of the return spring away from the intermediate sleeve plate is fixedly connected to the inner side of the first concave plate. The intermediate sleeve plate is sleeved on the second inner rod and is rotatably connected to the second inner rod through a bearing. The end of the return spring away from the convex sleeve plate is fixedly connected to the inner side of the second concave plate. Multiple fixed corner blocks are provided, and the multiple fixed corner blocks are respectively distributed at the bottom of the annular electric slide rail and the top of the circular chassis. The fixed corner block near the top is fixedly connected to the bottom of the annular electric slide rail, and the fixed corner block near the bottom is fixedly connected to the top of the circular chassis.

[0011] This invention provides an automated welding device for cranes based on electric arc welding. It has the following beneficial effects:

[0012] 1. This automated welding equipment for cranes based on electric arc welding filters out minute welding slag and dust from the flue gas by opening multiple dust-filtering holes on the outside of the annular shell. This prevents the minute welding slag and dust from being sucked into the annular shell and accumulating for a long time, causing blockage and affecting the ventilation effect. The arc-shaped scraper cleans the outer surface of the rotating annular shell by scraping, preventing the dust-filtering holes from becoming blocked by welding slag and dust after long-term filtration, thus affecting the ventilation effect. By setting return springs one, two, and three on both sides of the medium-sized sleeve plate and the convex sleeve plate respectively, the medium-sized sleeve plate and the convex sleeve plate are always in an extended trend to support the bottom of the annular electric slide rail. This prevents the weight of too many parts on the annular electric slide rail from affecting the driving effect of the vertical electric slide rail over a long period of time.

[0013] 2. This automated welding equipment for cranes based on electric arc welding is equipped with a fume extraction device. Multiple dust-filtering holes are opened on the outside of the annular shell to filter out minute welding slag and dust particles in the flue gas. This prevents these particles from being sucked into the annular shell and accumulating for extended periods, causing blockages and affecting ventilation. An annular filter element is installed inside the U-shaped slide rod to further purify the particulate-free flue gas, preventing poor purification and rapid diffusion of the flue gas under the pressure of the high-pressure air pump, which could affect the welding process. The high-pressure air pump sprays the purified gas onto the vertical electric slide rail to blow away dust from the track groove, preventing welding slag and dust from accumulating in the track groove after prolonged use and affecting its usability. The annular filter element can be directly removed through the annular cover plate and U-shaped slide rod for easy cleaning and replacement, preventing the filter element from reacting with the flue gas for extended periods, leading to increasingly poor purification and unusable operation.

[0014] 3. This automated welding equipment for cranes based on arc welding is equipped with a cleaning device. An arc-shaped scraper cleans the outer surface of the rotating annular shell, preventing the dust filter holes from becoming clogged with welding slag and dust after prolonged filtration, thus affecting ventilation. By fixing the bottom of the arc-shaped scraper to the top of the strip-shaped sleeve, the shape of the arc-shaped scraper is stabilized, preventing the scraper from being unable to maintain close contact with the outer surface of the annular shell due to external forces when sliding in contact with it, thus affecting the cleaning effect. A rotatable and resetting strip-shaped sleeve is set between the bottom corner plate and the top circular plate, which facilitates the rotation adjustment of the electric robotic arm without affecting it. This prevents the top annular plate from hitting the strip-shaped sleeve when adjusting the position of the electric robotic arm in the circumferential direction, making it difficult to continue rotating. A fixed through rod is set between the bottom corner plate and the top circular plate to limit the elastic connection of the strip-shaped sleeve, preventing the elastic connection of the sleeve from tilting or shifting due to the rotation spring when pushed by the electric robotic arm, thus affecting its use.

[0015] 4. This automated welding equipment for cranes based on electric arc welding is equipped with an auxiliary support device. By installing return springs one, two, and three on both sides of the medium-sized sleeve plate and the convex sleeve plate respectively, the medium-sized sleeve plate and the convex sleeve plate are always in an extended trend to provide bottom support for the bottom of the annular electric slide rail. This prevents the heavy weight of the annular electric slide rail from affecting the driving effect of the vertical electric slide rail over a long period of time when too many parts are installed on it. By setting the convex sleeve plate and the medium sleeve plate in the first concave plate and the second concave plate, the convex sleeve plate and the medium sleeve plate can only rotate to a vertical position at most. This prevents the convex sleeve plate and the medium sleeve plate from folding outward when folding after being fully extended, thus affecting the use. By setting foldable convex sleeve plates and medium sleeve plates between the annular electric slide rail and the circular chassis, the bottom of the annular electric slide rail is always kept away from one end of the circular chassis. This prevents a large amount of impurities accumulated on the circular chassis from adhering to the annular electric slide rail when the annular electric slide rail moves to contact the top surface of the circular chassis, thus affecting the use.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-4 This invention provides an automated welding equipment for cranes based on electric arc welding, including a circular chassis 1. The bottom of the circular chassis 1 is rotatably connected to an electric roller 2 via a rotating bolt. The top of the circular chassis 1 is fixedly connected to a vertical electric slide rail 3. A frame-shaped sleeve plate 4 is sleeved and slidably connected to the outside of the vertical electric slide rail 3. External connecting rods 5 are fixedly connected to all four sides of the frame-shaped sleeve plate 4. An annular electric slide rail 6 is fixedly connected to the end of the external connecting rods 5 away from the frame-shaped sleeve plate 4. A top ring plate 7 is rotatably connected to the top of the annular electric slide rail 6. An electric robotic arm 8 is fixedly connected to the top of the top ring plate 7. An electric arc welder 9 is fixedly connected to one end of the electric robotic arm 8. A fumigation device 10 is fixedly connected to the top of the top ring plate 7. A cleaning device 11 is fixedly connected to the outside of the annular electric slide rail 6. An auxiliary support device 12 is fixedly connected to the bottom of the annular electric slide rail 6.

[0027] The smoking device 10 includes an annular shell 1001, with a high-pressure air pump 1002 connected to the inner side of the annular shell 1001, and a dust filter hole 1003 opened on the outer side of the annular shell 1001.

[0028] Multiple electric rollers 2 are provided and distributed at the bottom of the circular chassis 1. Multiple cleaning devices 11 are provided and distributed on the outside of the annular electric slide rail 6. The bottom of the auxiliary support device 12 is fixedly connected to the top of the circular chassis 1.

[0029] The top of the annular shell 1001 is provided with a top opening annular hole 1004, and a U-shaped slide rod 1005 is slidably connected to the inner wall of the top opening annular hole 1004. An annular cover plate 1006 is fixedly connected to the top of the U-shaped slide rod 1005, and an annular filter element 1007 is fixedly connected to the bottom of the annular cover plate 1006.

[0030] The bottom of the annular shell 1001 is fixedly connected to the top of the top ring plate 7. The inner side of the U-shaped slide rod 1005 is fixedly connected to the outer side of the annular filter element 1007. Multiple U-shaped slide rods 1005 are provided, and multiple U-shaped slide rods 1005 are distributed at the bottom of the annular cover plate 1006. In use, after the equipment is moved to the processing area by the electric roller 2, the vertical electric slide rail 3 drives the frame-shaped sleeve plate 4 to move the outer connecting round rod 5 upward. When the outer connecting round rod 5 moves upward, it drives the annular electric slide rail 6 to move upward. When the annular electric slide rail 6 moves upward, it drives the top ring plate 7 and the outer cleaning device 11 to move upward together. When the top ring plate 7 moves upward, it drives the top electric mechanical arm 8 and the fumigation device 10 together. When the electric robotic arm 8 moves upward to the position where welding is required, the electric robotic arm 8 operates the telephone welder to perform automated welding on the crane. When the circular electric slide rail 6 moves upward, it stretches the bottom auxiliary support device 12. At the same time, the auxiliary support device 12 at the bottom of the circular electric slide rail 6 provides bottom support for the circular electric slide rail 6. The circular electric slide rail 6 drives the top ring plate 7 to rotate. The rotation of the top ring plate 7 drives the top electric robotic arm 8 and the fumigation device 10 to rotate together. When the fumigation device 10 rotates, its outer surface is in constant sliding contact with one side of the cleaning device 11. At this time, the cleaning device 11 performs scraping cleaning on the outer surface of the fumigation device 10.

[0031] High-pressure air pump 1002 draws air from the inside of the annular shell 1001, causing the gas around the outside of the annular shell 1001 to enter the inside of the annular shell 1001 through the dust filter holes 1003. Multiple dust filter holes 1003 are opened on the outside of the annular shell 1001 to filter out the tiny welding slag and dust in the flue gas. The flue gas entering the annular shell 1001 comes into contact with the annular filter element 1007 and is purified by the annular filter element 1007 before being discharged from the high-pressure air pump 1002. The annular filter element 1007 is set in the U-shaped slide bar 1005 to further purify the flue gas with particulate matter removed. The high-pressure air pump 1002 sprays the purified gas onto the vertical electric slide rail 3 to blow dust from the track groove. After long-term use, the annular filter element 1007 can be directly removed through the annular cover plate 1006 and the U-shaped slide bar 1005 for easy cleaning and replacement.

[0032] Please see Figures 1-8 This invention provides an automated welding equipment for cranes based on electric arc welding: a cleaning device 11 includes a bottom corner plate 1101, a rotary spring 1102 fixedly connected to the top of the bottom corner plate 1101, a strip-shaped sleeve rod 1103 fixedly connected to the top of the rotary spring 1102, an arc-shaped scraper 1104 fixedly connected to the top of the strip-shaped sleeve rod 1103, a top circular plate 1105 rotatably connected to the top of the strip-shaped sleeve rod 1103 via a bearing, a fixing rod 1106 fixedly connected to the bottom of the top circular plate 1105, one side of the bottom corner plate 1101 fixedly connected to the outside of the annular electric slide rail 6, multiple bottom corner plates 1101 are provided, and multiple bottom corner plates 1101 are distributed on the outside of the annular electric slide rail 6, the bottom of the fixing rod 1106 passes through the strip-shaped sleeve rod 1103 and is rotatably connected to the strip-shaped sleeve rod 1103, and the bottom of the fixing rod 1106 is fixedly connected to the top of the bottom corner plate 1101;

[0033] The auxiliary support device 12 includes a first concave plate 1201. A first inner rod 1202 is fixedly connected to the inner side of the first concave plate 1201. A medium-sized sleeve plate 1203 is sleeved on the outer side of the first inner rod 1202 and rotatably connected to it via bearings. A first return spring 1204 is fixedly connected to both sides of the medium-sized sleeve plate 1203 near the first concave plate 1201. A second return spring 1205 is fixedly connected to both sides of the medium-sized sleeve plate 1203 away from the first concave plate 1201. A second concave plate 1206 is fixedly connected to the end of the second return spring 1205 away from the medium-sized sleeve plate 1203. A second inner rod 1207 is fixedly connected to the inner side of the second concave plate 1206. A third inner rod 1208 is fixedly connected to the inner side of the second concave plate 1206. A convex sleeve plate 1209 is fitted on the outer side of rod 1208 and rotatably connected to it via bearings. Two return springs 1210 are fixedly connected to both sides of the convex sleeve plate 1209. Fixed corner blocks 1211 are rotatably connected to both sides of the convex sleeve plate 1209 away from the intermediate sleeve plate 1203 via rotating bolts. Multiple first inner rods 1202 are provided, and these first inner rods 1202 are distributed inside the first concave plate 1201. One end of the return spring 1204 away from the intermediate sleeve plate 1203 is fixedly connected to the inner side of the first concave plate 1201. The intermediate sleeve plate 1203 is fitted onto the second inner rod 1207 and rotatably connected to it via bearings. One end of the return spring 1210 away from the convex sleeve plate 1209 is fixedly connected to the first inner rod 1207. The inner side of the two concave plates 1206 is fixedly connected, and multiple fixed corner blocks 1211 are provided. The multiple fixed corner blocks 1211 are respectively distributed at the bottom of the annular electric slide rail 6 and the top of the circular chassis 1. The fixed corner blocks 1211 near the top are fixedly connected to the bottom of the annular electric slide rail 6, and the fixed corner blocks 1211 near the bottom are fixedly connected to the top of the circular chassis 1. In use, when the annular electric slide rail 6 drives the top ring plate 7 to rotate, it drives the top annular shell 1001 and the electric mechanical arm 8 to rotate together. When the annular shell 1001 rotates, its outer surface slides into contact with the arc-shaped scraper 1104 on the strip sleeve 1103. The arc-shaped scraper 1104 scrapes and cleans the outer surface of the rotating annular shell 1001. The bottom of 104 is fixedly set to the top of the strip-shaped sleeve 1103 to stabilize the shape of the arc-shaped scraper 1104. When the electric robotic arm 8 rotates with the top ring plate 7 and contacts the strip-shaped sleeve 1103, it pushes the strip-shaped concave rod to rotate around the fixed through rod 1106 and drives the rotary spring 1102 to rotate and tighten. When the electric robotic arm 8 passes the strip-shaped sleeve 1103, the strip-shaped sleeve 1103 loses its thrust. At this time, the rotary spring 1102 drives the strip-shaped sleeve 1103 to rotate back to the initial position tangent to the outer surface of the annular shell 1001 through the rotational force. By setting the rotatable and resetable strip-shaped sleeve 1103 between the bottom corner plate 1101 and the top circular plate 1105, the rotation adjustment of the electric robotic arm 8 is not affected.A fixed through rod 1106 is provided between the bottom corner plate 1101 and the top circular plate 1105 to limit the elastically connected strip sleeve 1103. When the annular electric slide rail 6 moves upward with the frame-shaped sleeve plate 4, it drives the bottom fixed corner block 1211 to move. When the fixed corner block 1211 moves upward, it drives the convex sleeve plate 1209 on one side to move upward. When the convex sleeve plate 1209 moves upward with the fixed corner block 1211, it rotates around the third inner rod 1208 and drives the second concave plate 1206 to move upward together through the third inner rod 1208. When the second concave plate 1206 moves upward, it drives the intermediate sleeve plate 1203 to move upward through the second inner rod 1207. A return spring 1 is provided on both sides of the intermediate sleeve plate 1203 and the convex sleeve plate 1209. 204. The second and third return springs 1205 and 1210 ensure that the intermediate sleeve 1203 and the convex sleeve 1209 are always extended, providing bottom support for the bottom of the annular electric slide rail 6. By setting the convex sleeve 1209 and the intermediate sleeve 1203 within the first concave plate 1201 and the second concave plate 1206, the convex sleeve 1209 and the intermediate sleeve 1203 can only rotate to a vertical position at most. When the annular electric slide rail 6 moves downward, it pushes the convex sleeve 1209 and the intermediate sleeve 1203 closer together for folding. By setting the foldable convex sleeve 1209 and the intermediate sleeve 1203 between the annular electric slide rail 6 and the circular base 1, the bottom of the annular electric slide rail 6 is always kept at a distance from one end of the circular base 1.

[0034] In operation, the electric roller 2 moves the equipment to the processing area, and the vertical electric slide rail 3 drives the frame plate 4 to move the outer connecting rod 5 upward. As the outer connecting rod 5 moves upward, it drives the annular electric slide rail 6 upward. The upward movement of the annular electric slide rail 6 causes the top ring plate 7 and the outer cleaning device 11 to move upward together. The upward movement of the top ring plate 7 causes the top electric robotic arm 8 and the fumigation device 10 to move upward together. When the electric robotic arm 8 moves to the position requiring welding, the electric robotic arm 8 operates the telephone welding device to move the crane... When performing automated welding operations, the ring-shaped electric slide rail 6 moves upward and stretches the bottom auxiliary support device 12. At the same time, the auxiliary support device 12 at the bottom of the ring-shaped electric slide rail 6 provides bottom support for the ring-shaped electric slide rail 6. The ring-shaped electric slide rail 6 drives the top ring plate 7 to rotate. The rotation of the top ring plate 7 drives the top electric robotic arm 8 and the fumigation device 10 to rotate together. When the fumigation device 10 rotates, its outer surface is in constant sliding contact with one side of the cleaning device 11. At this time, the cleaning device 11 performs scraping cleaning on the outer surface of the fumigation device 10.

[0035] High-pressure air pump 1002 draws air from the inside of the annular shell 1001, causing the gas surrounding the outside of the annular shell 1001 to enter the interior through the dust filter holes 1003. Multiple dust filter holes 1003 on the outside of the annular shell 1001 filter out fine welding slag and dust from the flue gas. The flue gas entering the annular shell 1001 comes into contact with the annular filter element 1007, is purified by the annular filter element 1007, and then exits from the high-pressure air pump 1002. The flue gas with particulate matter removed is further purified by installing the annular filter element 1007 inside the U-shaped slide bar 1005. The purified gas is then sprayed by the high-pressure air pump 1002 onto the vertical electric slide rail 3 to blow dust from the track groove. After prolonged use, the annular filter element 1007 can be directly removed via the annular cover plate 1006 and U-shaped slide bar 1005 for easy cleaning and replacement. When the annular electric slide rail 6 drives the top annular plate 7 to rotate, it causes the top annular shell 1001 and the electric mechanical arm 8 to rotate together. When the annular shell 1001 rotates, its outer surface slides into contact with the arc-shaped scraper 1104 on the strip-shaped sleeve 1103. The arc-shaped scraper 1104 scrapes and cleans the outer surface of the rotating annular shell 1001. The bottom of the arc-shaped scraper 1104 is fixed to the top of the strip-shaped sleeve 1103 to stabilize the shape of the arc-shaped scraper 1104. As the top annular plate 7 rotates, the electric mechanical arm 8 rotates to contact the strip-shaped sleeve 1103. Upon contact, the push rod rotates around the fixed through rod 1106, causing the rotary spring 1102 to rotate and tighten. When the electric robotic arm 8 passes over the strip rod 1103, the strip rod 1103 loses its thrust. At this time, the rotary spring 1102 drives the strip rod 1103 to rotate back to the initial position tangent to the outer surface of the annular shell 1001 through the rotational force. The rotatable and reset strip rod 1103 is set between the bottom corner plate 1101 and the top circular plate 1105 to facilitate the rotation adjustment of the electric robotic arm 8 without affecting it. The fixed through rod 1106 is set between the bottom corner plate 1101 and the top circular plate 1105 to limit the elastically connected strip rod 1103. The annular electric slide rail 6 moves with the frame sleeve When plate 4 moves upward, it causes the bottom fixed corner block 1211 to move. When fixed corner block 1211 moves upward, it causes the convex sleeve plate 1209 on one side to move upward. As the fixed corner block 1211 moves upward, the convex sleeve plate 1209 rotates around the third inner rod 1208 and drives the second concave plate 1206 to move upward together through the third inner rod 1208. When the second concave plate 1206 moves upward, it drives the medium sleeve plate 1203 to move upward through the second inner rod 1207. By setting return springs 1204, 1205 and 1210 on both sides of the medium sleeve plate 1203 and the convex sleeve plate 1209 respectively, the medium sleeve plate 1203 and the convex sleeve plate 1209 are always in an unfolded trend to provide bottom support for the bottom of the annular electric slide rail 6.By providing a convex sleeve 1209 and a medium sleeve 1203 within the first concave plate 1201 and the second concave plate 1206, the convex sleeve 1209 and the medium sleeve 1203 can only rotate to a vertical position at most. When the annular electric slide rail 6 moves downward, it pushes the convex sleeve 1209 and the medium sleeve 1203 closer together for folding. By providing foldable convex sleeve 1209 and medium sleeve 1203 between the annular electric slide rail 6 and the circular base 1, the bottom of the annular electric slide rail 6 is always kept at a distance from one end of the circular base 1.
