Description

Technical Field

[0001] The present invention belongs to the technical field of pole maintenance, and specifically relates to a maintenance device and method for the production of prestressed poles based on low-carbon materials. Background Art

[0002] With the enhancement of people's environmental protection awareness, the application of environmentally friendly materials is becoming more and more extensive in engineering practice. Ordinary concrete poles rely on portland cement, and their production requires high-temperature calcination, consuming a large amount of coal or electricity. Traditional poles are at risk of being phased out, and it is urgent to promote the low-carbon transformation of the building materials industry. At present, low-carbon and environmentally friendly materials have begun to be used in the manufacture of prestressed poles, which can reduce carbon emissions and resource consumption during the production process while improving the mechanical properties and durability of the poles. In the production of poles, after centrifugal molding, the poles need to be maintained before they can be used.

[0003] For example, the invention application with the publication number CN118906200A in the field of steam curing technology discloses a steam curing device for cement poles, which includes a box body with a lifting door and a curing rack fixedly arranged in the box body. The lifting door is arranged on the front side of the box body, and a steam spray pipe with its end penetrating through the rear side wall of the box body is arranged on the curing rack; it also includes a pair of electric guide rails installed at the bottom of the front side of the box body, and linear motors I and II are arranged on both of the two electric guide rails.

[0004] Combined with the above case and the actual situation, we found the following problems: When maintaining poles, whether it is a collective curing kiln or a single curing box, the steam nozzles and poles inside are usually fixed. Due to the long length of the poles, in order to ensure uniform curing, multiple groups of steam nozzles need to be arranged along the poles. Moreover, because the nozzles are fixed, local overheating is likely to occur during long-term curing, affecting the curing effect. Summary of the Invention

[0005] The purpose of the present invention is to provide a maintenance device and method for the production of prestressed poles based on low-carbon materials, so as to solve the problems in the prior art that the steam nozzles and poles are usually fixed, multiple groups of steam nozzles need to be arranged, and local overheating is likely to occur, affecting the curing effect.

[0006] To achieve the above purpose, the present invention provides a maintenance device for the production of prestressed poles based on low-carbon materials, including a curing box. An activity component for driving the pole to rotate is arranged in the curing box, and a steam component for releasing steam is arranged in the curing part.

[0007] In this setting, by arranging the activity component and the steam component, during curing, the pole can be rotated and the steam component can also be moved, thereby improving the curing effect and making the curing more uniform.

[0008] The movable component includes two abutting structures symmetrically arranged left and right for fixing the electric pole, two rotating structures symmetrically arranged left and right for driving the abutting structures to rotate, and a translation structure for driving the abutting structures to move left and right;

[0009] The rotating structure includes a first motor, a rotating cylinder coaxially fixed to the output shaft of the first motor, and a transmission rod slidably connected to the rotating cylinder. The outer wall of the transmission rod is symmetrically provided with outwardly protruding flanges on the left and right. The inner end of the transmission rod is coaxially fixed with a fixed rod, and the inner end of the fixed rod is symmetrically provided with fixed cylinders up and down;

[0010] In this setting, the first motor drives the rotating cylinder to rotate, and under the action of the flanges, the transmission rod and the fixed rod are driven to rotate, thereby driving the electric pole to rotate reciprocally, making the electric pole more evenly cured by steam curing;

[0011] The abutting structure includes two movable rods symmetrically arranged up and down and anti-slip pads fixedly connected to the outer ends of the movable rods. The inner ends of the movable rods are slidably connected in the corresponding fixed cylinders. A first spring is provided between the inner ends of the movable rods and the bottom surfaces of the corresponding fixed cylinders. A limiting structure for controlling the outward extension of the right abutting structure is provided on the right fixed rod;

[0012] In this setting, when the abutting structure enters the electric pole, since the diameter of the electric pole gradually decreases from left to right, the left anti-slip pad will closely adhere to the inner wall of the electric pole under the action of the first spring and then fix the electric pole through friction. After the limiting structure of the right anti-slip pad is released, it will also closely adhere to the inner wall of the electric pole under the action of the first spring, enabling the electric pole to rotate synchronously with the rotating structure;

[0013] The steam component includes two transmission structures symmetrically arranged before and after on both sides of the left rotating structure. Steam nozzles are arranged in a staggered manner before and after on the two transmission structures;

[0014] In this setting, the transmission structure drives the steam nozzles to slide left and right reciprocally, thereby changing the steam ejection point and avoiding local overheating during curing due to a fixed ejection point.

[0015] In the technical solution of the present invention, the curing box includes a box body and a box cover. A curing part for placing the electric pole is provided in the middle of the box body. First installation parts and second installation parts are provided on both the left and right sides of the curing part. The first installation part and the curing part are separated by a fixedly arranged bracket. The first installation part and the corresponding second installation part on the same side are separated by a partition board. The box cover is arranged above the curing part and the first installation part, and the second installation part is in a sealed state.

[0016] In this setting, it is ensured that after the box cover is closed, the curing part and the first installation part are in a sealed state, and at the same time, the second installation part is in a sealed state, preventing high-temperature steam from entering the second installation part.

[0017] In the technical solution of the present invention, the top surface of the bracket is an arc-shaped concave surface for facilitating the placement of the electric pole. A number of balls are arranged regularly on the top surface of the bracket. The balls are embedded in the top surface of the bracket and can rotate freely. The middle part of the outer side wall of the bracket is symmetrically fixed with stop bars in the front and back.

[0018] In this setting, the balls reduce the friction between the electric pole and the bracket when the electric pole rotates, avoiding damage to the electric pole during rotation when it is not fully formed. The stop bars can prevent the electric pole from swaying left and right, resulting in the failure of the abutting structure to be fully fixed to the electric pole.

[0019] In the technical solution of the present invention, the first motor is fixed on the outer side inner wall corresponding to the second mounting portion. The rotating cylinder passes through the corresponding partition plate and is slidably connected to the transmission rod on the same side. A sliding cavity for the transmission rod to slide is provided in the rotating cylinder. A sliding groove for the limiting structure to slide is provided on the right fixed rod. A jack is provided on the outer side of the wall of the right fixed cylinder.

[0020] In this setting, the first motor drives the rotating cylinder to rotate, thereby driving the transmission rod to rotate. At the same time, since the transmission rod is slidably connected to the rotating cylinder, the translation structure will not be blocked by the rotating cylinder when driving the abutting structure.

[0021] In the technical solution of the present invention, the limiting structure includes a movable ring sleeved on the right fixed rod, insertion rods symmetrically fixed on the front side wall of the movable ring up and down, and a connecting rod radially arranged and fixedly connected to the inner wall of the movable ring. A slot adapted to the insertion rod is provided on the right movable rod. The connecting rod passes through the sliding groove. The middle part of the connecting rod is in a circular plate shape. The sliding groove is adapted to the shape of the connecting rod. A second spring is provided between the outer side of the middle part of the sliding groove and the connecting rod.

[0022] In this setting, the right abutting structure is blocked when it moves to the right stop bar. The right anti-slip pad continues to move towards the middle. The stop bar blocks the movable ring and drives the insertion rod to withdraw from the slot and the jack, thereby releasing the movable rod, so that the anti-slip pad is tightly fixed to the inner wall of the electric pole. By setting the second spring, the insertion rod can be pushed back to its original position when the curing ends, facilitating the next use.

[0023] In the technical solution of the present invention, the translation structure includes a second motor fixed on the outer side inner wall of the left second mounting portion, a first rotating rod coaxially fixed to the output shaft of the second motor, and two connecting mechanisms connected to the corresponding fixed rods. The connecting mechanism includes a base rod and a clamping ring fixed on the base rod. The clamping ring is embedded in the wall of the corresponding fixed rod.

[0024] In the technical solution of the present invention, a second limiting groove for the left - right sliding of the connecting mechanism is provided in the middle of the bottom surface of the first mounting portion, and threaded portions are provided on the rod wall of the first rotating rod corresponding to the second limiting groove, and the threaded directions of the left - and right - hand threaded portions are opposite.

[0025] In this setting, the second motor drives the first rotating rod to rotate, so that the threaded portion drives the base rod and the clamping ring to move synchronously towards the middle. Due to the existence of the clamping ring, the abutting structures on both sides will be driven to move relatively towards the middle.

[0026] In the technical solution of the present invention, the transmission structure includes a second rotating rod rotatably connected to the inner wall of the left side of the second mounting portion on the left end, a driven gear coaxially fixed to the right end of the second rotating rod, and a third rotating rod arranged in parallel outside the second rotating rod. The second rotating rod and the corresponding third rotating rod on the same side are driven by a crawler. A driving gear is coaxially fixed to the left end of the rotating cylinder, and the driving gear meshes with the driven gear steam nozzle.

[0027] In the technical solution of the present invention, the middle part of the third rotating rod located between the curing parts is a threaded rod, the third rotating rod is threadedly connected to the base of the steam nozzle, first limiting grooves are symmetrically provided on the front and rear side walls of the curing part, the outer end of the base of the steam nozzle is embedded in the corresponding first limiting groove and the steam nozzle is slidably connected to the corresponding first limiting groove. The steam nozzle is provided with a telescopic metal bellows, one end of the metal bellows is communicated with the corresponding steam nozzle, and the other end is communicated with a steam pipe. The steam pipe passes through the front side wall of the second mounting portion on the right and is communicated with an external steam generating device.

[0028] In this setting, when the rotating cylinder rotates, the driving gear will drive the second rotating rods on both sides to rotate synchronously through the driven gears on both sides, and then drive the third rotating rods on both sides to rotate through the crawler. At this time, the steam nozzle will reciprocally slide along the first limiting groove to spray steam on the electric pole.

[0029] On the other hand, the present invention also provides a curing method for prestressed electric poles produced based on low - carbon materials, using the above - mentioned curing equipment for prestressed electric poles produced based on low - carbon materials, including the following steps:

[0030] S1. Lift the statically - shaped electric pole into the curing part, place the larger - diameter end on the left bracket and the smaller - diameter end on the right bracket, and close the box cover after placement;

[0031] S2. After closing the box cover, start the second motor to drive the first rotating rod to rotate, so that the threaded portion drives the base rod and the clamping ring to move synchronously towards the middle. The left abutting structure extends from the middle of the left side of the electric pole until the anti - slip pad is completely in close contact with the inner wall of the electric pole;

[0032] S3, when the abutment structure on the right side moves to the blocking rod on the right side, at this time, the anti-skid pad on the right side has completely entered the middle part of the right side of the pole, and after continuing to move toward the middle, the blocking rod will block the movable ring and drive the plug rod to withdraw from the slot and the socket, thereby releasing the movable rod, so that the first spring pushes the anti-skid pad to completely adhere to the inner wall of the pole, and the second motor is turned off;

[0033] S4. After the pole is fixed, the external steam generating device and the first motor are started simultaneously to drive the drum to rotate, and the transmission rod and the fixing rod are driven to rotate under the action of the flange, thereby driving the pole to reciprocate;

[0034] S5. While the drum is rotating, the active gear will synchronously drive the second rotating rods on both sides to rotate through the driven gears on both sides, and then drive the third rotating rods on both sides to rotate through the crawler belt. At this time, the steam nozzle will reciprocate along the first limit groove to spray steam toward the pole;

[0035] S6. After the maintenance is completed, the first motor is turned off and the second motor is started, so that the first rotating rod rotates in the opposite direction, driving the abutment structures on both sides to move outward. The abutment structure on the left is directly separated from the pole, and the abutment structure on the right side is pressed back into the fixed tube as the diameter of the pole gradually decreases to the left. When the insertion rod enters the insertion hole under the action of the second spring, the insertion rod will abut the movable rod. As the abutment structure on the right side continues to move right, the movable rod continues to be pressed back into the fixed tube until the slot is exposed, and the insertion rod is pushed into the slot by the second spring to complete the reset.

[0036] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0037] 1. In the present invention, by setting a movable component, during maintenance, the second motor is started to drive the first rotating rod to rotate and drive the abutment structures on both sides to move synchronously toward the middle, and the left abutment structure extends from the middle part of the left side of the pole until the anti-skid pad is completely in close contact with the inner wall of the pole; when the abutment structure on the right side moves to the right-side blocking rod, the anti-skid pad on the right side has completely entered the middle part of the right side of the pole, and after continuing to move toward the middle, the blocking rod will block the movable ring and drive the insertion rod to withdraw from the slot and the socket, and then release the movable rod, so that the first spring pushes the anti-skid pad to be completely in close contact with the inner wall of the pole so that the pole is fixed, and at this time the first motor is started again to drive the rotating drum to rotate, and under the action of the flange, the transmission rod and the fixed rod are driven to rotate, and then the pole is driven to reciprocate, so that the pole can be evenly in contact with the steam, thereby improving the maintenance effect.

[0038] 2. In the present invention, by providing a steam assembly, while the rotating drum is rotating, the driving gear will synchronously drive the second rotating rods on both sides to rotate through the driven gears on both sides, and then drive the third rotating rods on both sides to rotate through the crawler. At this time, the steam nozzle will reciprocally slide along the first limiting groove to spray steam onto the electric pole, making the steam spraying point unfixed, avoiding the situation of excessive local temperature during curing. At the same time, since the steam nozzle of this device can move, the usage amount of the steam nozzle is greatly reduced, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The following combines the accompanying drawings to describe the detailed implementation mode of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the detailed implementation mode

[0056] Unless otherwise clearly stated, throughout the specification, the term "including" or its variations such as "comprising" or "including" etc. will be understood to include the stated elements or components, without excluding other elements or other components

[0057] Refer to Figures 1 - 12 As shown, this embodiment provides a technical solution

[0058] A curing equipment and method for prestressed electric poles produced based on low-carbon materials, including a curing box 1. A moving component 2 for driving the electric pole to rotate is arranged in the curing box 1, and a steam component 3 for releasing steam is arranged in the curing part 13. By setting the moving component 2 to drive the electric pole to rotate, it makes the electric pole contact with steam more evenly during curing. By setting the steam component 3, when curing the electric pole, the steam ejection point is not fixed, and steam can be ejected more evenly, avoiding excessive local temperature and affecting the curing effect

[0059] The moving component 2 includes a contact structure 22, two symmetrically arranged rotating structures 21 on the left and right for driving the contact structure 22 to rotate, and a translational structure 24 for driving the contact structure 22 to move left and right. The electric pole is fixed by two symmetrically arranged contact structures 22 on the left and right, so that the electric pole rotates synchronously with the rotating structure 21 during curing. By setting the translational structure 24 to adjust the position of the contact structure 22, it avoids the contact structure 22 affecting the placement and removal of the electric pole

[0060] The rotating structure 21 includes a first motor 211, a rotating cylinder 212 coaxially fixed to the output shaft of the first motor 211, and a transmission rod 214 slidably connected to the rotating cylinder 212. Outer convex flanges 215 are symmetrically arranged on the front and rear outer walls of the transmission rod 214. A fixed rod 25 is coaxially fixed to the inner end of the transmission rod 214. Fixed cylinders 251 are symmetrically arranged on the upper and lower sides of the inner end of the fixed rod 25. During curing, the first motor 211 drives the rotating cylinder 212 to rotate, and drives the transmission rod 214 and the fixed rod 25 to rotate under the action of the flanges 215, thereby driving the electric pole to rotate reciprocally;

[0061] The abutting structure 22 includes two symmetrically arranged movable rods 221 up and down and anti-slip pads 222 fixedly connected to the outer ends of the movable rods 221. The inner ends of the movable rods 221 are slidably connected in the corresponding fixed cylinders 251. A first spring 223 is arranged between the inner end of the movable rod 221 and the bottom surface of the corresponding fixed cylinder 251. A limiting structure 26 for controlling the outward extension of the right abutting structure 22 is arranged on the right fixed rod 25. When the abutting structure 22 enters the electric pole, since the diameter of the electric pole gradually decreases from left to right, the anti-slip pad 222 will closely adhere to the inner wall of the electric pole under the action of the first spring 223, thereby fixing the electric pole through friction;

[0062] The steam assembly 3 includes two transmission structures 31 symmetrically arranged on the front and rear sides of the left rotating structure 21. Steam nozzles 32 are staggered front and rear on the two transmission structures 31. During curing, the transmission structure 31 drives the steam nozzles 32 to slide left and right reciprocally, thereby changing the steam ejection point and avoiding local overheating during curing due to the fixed ejection point.

[0063] In addition, as Figures 1 - 4 shown, the curing box 1 includes a box body 11 and a box cover 12. A curing part 13 for placing the electric pole is arranged in the middle of the box body 11. First installation parts 14 and second installation parts 15 are arranged on both the left and right sides of the curing part 13. The first installation part 14 and the curing part 13 are separated by a fixedly arranged bracket 16. The first installation part 14 and the corresponding second installation part 15 on the same side are separated by a partition board. The first installation part 14 allows the abutting structure 22 to slide left and right. The box cover 12 is arranged above the curing part 13 and the first installation part 14 to ensure that the curing part 13 and the first installation part 14 are in a sealed state during use, and the second installation part 15 is always in a sealed state.

[0064] Furthermore, the top surface of the bracket 16 is an arc-shaped concave surface for facilitating the placement of the electric pole. A number of balls 17 are regularly arranged on the top surface of the bracket 16. The balls 17 are embedded in the top surface of the bracket 16 and can rotate freely. The balls 17 reduce the friction between the electric pole and the bracket 16 when the electric pole rotates, avoiding damage when the electric pole is not fully formed. The middle parts of the front and rear outer walls of the bracket 16 are symmetrically fixed with stop rods 18. The stop rods 18 can prevent the electric pole from shaking left and right, resulting in the abutting structure 22 being unable to fully fix with the electric pole.

[0065] In addition, as Figures 5 - 9 shown, the first motor 211 is fixed on the outer inner wall corresponding to the second mounting portion 15. The rotating cylinder 212 passes through the corresponding partition plate and is slidably connected to the transmission rod 214 on the same side. A sliding cavity 213 for the transmission rod 214 to slide is provided inside the rotating cylinder 212. The rotating cylinder 212 is driven by the first motor 211 to rotate, thereby driving the transmission rod 214 to rotate. At the same time, since the transmission rod 214 is slidably connected to the rotating cylinder 212, the translation structure 24 drives the abutting structure 22 without being blocked by the rotating cylinder 212. A chute 253 for limiting the sliding of the limiting structure 26 is provided on the right fixed rod 25, and a jack 252 is provided on the outer side of the barrel wall of the right fixed cylinder 251.

[0066] Furthermore, the limiting structure 26 includes a movable ring 261 sleeved on the right fixed rod 25, insertion rods 262 symmetrically fixed on the front side wall of the movable ring 261 up and down, and a connecting rod 263 radially arranged and fixedly connected to the inner wall of the movable ring 261. A slot 23 adapted to the insertion rod 262 is provided on the right movable rod 221. The connecting rod 263 passes through the chute 253. The middle part of the connecting rod 263 is in a circular plate shape, and the chute 253 is adapted to the shape of the connecting rod 263. When fixing the electric pole, the abutting structure 22 on the right will be blocked when moving to the right stop rod 18. The anti-slip pad 222 on the right has completely entered the middle part on the right side of the electric pole. After continuing to move towards the middle, the stop rod 18 will block the movable ring 261 and drive the insertion rod 262 to withdraw from the slot 23 and the jack 252, thereby releasing the movable rod 221. It should be noted that the abutting structure 22 on the right when not in use can enter from the opening at the right end of the electric pole without being blocked by the electric pole. A second spring 264 is provided between the outer side of the middle part of the chute 253 and the connecting rod 263. By setting the second spring 264, the insertion rod 262 can be pushed to reset when the maintenance is completed, which is convenient for next use.

[0067] In addition, as Figure 10 shown, the translation structure 24 includes a second motor 241 fixed on the outer inner wall of the left second mounting portion 15, a first rotating rod 242 coaxially fixed to the output shaft of the second motor 241, and two connecting mechanisms 244 connected to the corresponding fixed rods 25. The connecting mechanism 244 includes a base rod 2441 and a snap ring 2442 fixed on the base rod 2441. The snap ring 2442 is embedded in the rod wall of the corresponding fixed rod 25. The snap ring 2442 can neither affect the rotation of the fixed rod 25 nor drive the fixed rod 25 to move left and right;

[0068] In the middle of the bottom surface of the first installation part 14, there is a second limiting groove 141 for the left - right sliding of the connecting mechanism 244. The second limiting groove 141 limits the connecting mechanism 244 to prevent the connecting mechanism 244 from rotating in the vertical plane. At the corresponding position of the rod wall of the first rotating rod 242 and the second limiting groove 141, there are threaded parts 243, and the threaded directions of the left - right two threaded parts 243 are opposite, ensuring that the moving directions of the left - right two connecting mechanisms 244 are opposite. During maintenance, the second motor 241 drives the first rotating rod 242 to rotate, so that the threaded part 243 drives the base rod 2441 and the clamping ring 2442 to move synchronously towards the middle. Due to the existence of the clamping ring 2442, the two abutting structures 22 on both sides will be driven to move relatively towards the middle.

[0069] Furthermore, as Figures 11 - 12 shown, the transmission structure 31 includes a second rotating rod 311 whose left end is rotatably connected to the inner wall on the left side of the left - hand second installation part 15, a driven gear 312 coaxially fixed to the right end of the second rotating rod 311, and a third rotating rod 314 arranged in parallel on the outside of the second rotating rod 311. The second rotating rod 311 and the corresponding - side third rotating rod 314 are driven by a crawler 313. When the second rotating rod 311 rotates, it will drive the third rotating rod 314 to rotate synchronously through the crawler 313. A driving gear 27 is coaxially fixed to the left end of the rotating cylinder 212. The driving gear 27 meshes with the driven gear 312 of the steam nozzle 32. By setting the steam nozzle 32, steam is sprayed onto the electric pole for maintenance. The part of the middle of the third rotating rod 314 between the maintenance parts 13 is a threaded rod. When the third rotating rod 314 rotates, it will drive the steam nozzle 32 to slide left - right reciprocally. The third rotating rod 314 is threadedly connected to the base of the steam nozzle 32;

[0070] Specifically, the front and rear side walls of the maintenance part 13 are symmetrically provided with first limiting grooves 131. The outer ends of the base of the steam nozzle 32 are embedded in the corresponding first limiting grooves 131 and the steam nozzle 32 is slidably connected to the corresponding first limiting grooves 131. By setting the first limiting grooves 131, the steam nozzle 32 is limited to prevent the steam nozzle 32 from rotating together with the third rotating rod 314. The steam nozzle 32 is provided with a metal bellows 33. The retractable metal bellows 33 can prevent the steam nozzle 32 from being blocked by the pipeline when sliding left - right. One end of the metal bellows 33 is communicated with the corresponding steam nozzle 32, and the other end is communicated with a steam pipe 34. The steam pipe 34 passes through the front side wall of the right - hand second installation part 15 and is communicated with an external steam generating device. While the rotating cylinder 212 rotates, the driving gear 27 will drive the second rotating rods 311 on both sides to rotate synchronously through the driven gears 312 on both sides, and then drive the third rotating rods 314 on both sides to rotate through the crawler 313. At this time, the steam nozzle 32 will reciprocally slide along the first limiting groove 131 to spray steam onto the electric pole. It should be noted that the steam generating device is a commonly used existing technology in this field and will not be elaborated here.

[0071] The present invention also provides a maintenance method for prestressed pole production based on low-carbon materials, using the above-mentioned maintenance equipment for prestressed pole production based on low-carbon materials, comprising the following steps:

[0072] S1, hoist the pole after static shaping into the maintenance part 13, place the end with larger diameter on the left bracket 16, and the end with smaller diameter on the right bracket 16, and close the box cover 12 after placement;

After closing the box cover 12, start the second motor 241 to drive the first rotating rod 242 to rotate, so that the threaded portion 243 drives the base rod 2441 and the clamping ring 2442 to move synchronously toward the middle, and the left abutment structure 22 extends from the middle of the left side of the pole until the anti-slip pad 222 is completely in close contact with the inner wall of the pole;

[0074] S3, when the right side abutment structure 22 moves to the right side blocking rod 18, at this time, the right side anti-skid pad 222 has completely entered the middle part of the right side of the pole, and after continuing to move toward the middle, the blocking rod 18 will block the movable ring 261 and drive the plug rod 262 to withdraw from the slot 23 and the plug hole 252, thereby releasing the movable rod 221, so that the first spring 223 pushes the anti-skid pad 222 to completely fit against the inner wall of the pole, and the second motor 241 is turned off;

[0075] S4. After the pole is fixed, the external steam generating device and the first motor 211 are started simultaneously to drive the drum 212 to rotate, and the transmission rod 214 and the fixing rod 25 are driven to rotate under the action of the flange 215, thereby driving the pole to reciprocate;

[0076] S5. When the drum 212 rotates, the driving teeth 27 will synchronously drive the second rotating rods 311 on both sides to rotate through the driven teeth 312 on both sides, and then drive the third rotating rods 314 on both sides to rotate through the crawler belts 313. At this time, the steam spray head 32 will reciprocate along the first limiting groove 131 to spray steam toward the pole;

[0077] S6. After the maintenance is completed, the first motor 211 is turned off and the second motor 241 is started, so that the first rotating rod 242 rotates in the opposite direction, driving the abutment structures 22 on both sides to move outward, and the abutment structure 22 on the left side is directly separated from the pole. As the diameter of the pole gradually decreases to the left, the movable rod 221 will be pressed back into the fixed tube 251. When the insertion rod 262 enters the insertion hole 252 under the action of the second spring 264, the insertion rod 262 will abut against the movable rod 221. As the abutment structure 22 on the right side continues to move right, the movable rod 221 continues to be pressed back into the fixed tube 251 until the slot 23 is exposed, and the insertion rod 262 is pushed into the slot 23 by the second spring 264 to complete the reset.
