Description

Technical Field

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

[0002] As environmental awareness grows, the use of environmentally friendly materials is becoming increasingly widespread in engineering practice. Conventional concrete poles rely on Portland cement, which requires high-temperature calcination and consumes large amounts of coal or electricity. This puts traditional poles at risk of obsolescence, necessitating an urgent transition to a low-carbon building materials industry. Currently, low-carbon, environmentally friendly materials are being used in the manufacture of prestressed poles. This reduces carbon emissions and resource consumption during production while improving the poles' mechanical properties and durability. During pole production, after centrifugal forming, the poles require maintenance before use.

[0003] For example, the invention application with publication number CN118906200A in the field of steam curing technology discloses a cement pole steam curing device, which includes a box with a lifting door and a curing frame fixedly arranged in the box, the lifting door is arranged on the front side of the box, and the curing frame is provided with a steam nozzle whose end passes through the rear wall of the box; it also includes a pair of electric guide rails installed at the bottom of the front side of the box, and both of the electric guide rails are provided with linear motor I and linear motor II.

[0004] Combining the above cases and actual conditions, we found the following problems: When maintaining electric poles, whether it is a collective maintenance kiln or a single maintenance box, the internal steam nozzles and the poles are usually fixed. Due to the long length of the poles, in order to maintain uniformity during maintenance, it is necessary to set up multiple groups of steam nozzles along the poles. Moreover, since the nozzles are fixed, it is easy to cause local excessive temperature during long-term maintenance, affecting the maintenance effect. Summary of the Invention

[0005] The purpose of the present invention is to provide maintenance equipment and methods for prestressed pole production based on low-carbon materials, so as to solve the problem in the prior art that steam nozzles and poles are usually fixed, multiple groups of steam nozzles need to be set up, and local temperatures are easily excessively high, affecting the maintenance effect.

[0006] To achieve the above-mentioned object, the present invention provides a maintenance device for the production of prestressed electric poles based on low-carbon materials, comprising a maintenance box, a movable component for driving the electric pole to rotate is provided in the maintenance box, and a steam component for releasing steam is provided in the maintenance part;

[0007] This setting provides movable components and steam components. During maintenance, the poles can be rotated and the steam components can be moved, thereby improving the maintenance effect and making the maintenance more uniform.

[0008] The movable assembly includes two left-right symmetrical abutment structures for fixing the pole, two left-right symmetrical rotation structures for driving the abutment structures to rotate, and a translation structure for driving the abutment structures to move left and right;

[0009] The rotating structure includes a first motor, a rotating drum coaxially fixed to the output shaft of the first motor, and a transmission rod slidably connected to the rotating drum, wherein the outer wall of the transmission rod is symmetrically provided with outwardly protruding flanges, the inner end of the transmission rod is coaxially fixed with a fixing rod, and the inner end of the fixing rod is symmetrically provided with a fixing drum;

[0010] In this arrangement, the first motor drives the drum to rotate, and under the action of the flange, the transmission rod and the fixed rod are driven to rotate, thereby driving the pole to rotate back and forth, so that the pole is more evenly steam cured;

[0011] The abutment structure includes two vertically symmetrical movable rods and anti-slip pads fixedly connected to the outer ends of the movable rods. The inner ends of the movable rods are slidably connected to 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. The right fixed rod is provided with a limiting structure for controlling the extension of the right abutment structure.

[0012] In this arrangement, when the abutment structure enters the interior of the pole, as the diameter of the pole gradually decreases from left to right, the left anti-slip pad will cling to the inner wall of the pole under the action of the first spring, thereby fixing the pole through friction. After the limiting structure is released, the right anti-slip pad will also cling to the inner wall of the pole under the action of the first spring, allowing the pole to rotate synchronously with the rotating structure.

[0013] The steam assembly includes two transmission structures symmetrically arranged on both sides of the left rotating structure, and steam nozzles are staggered on the two transmission structures.

[0014] In this setting, the transmission structure drives the steam nozzle to slide back and forth left and right, thereby changing the steam ejection point, avoiding the local excessive temperature during maintenance due to a fixed ejection point.

[0015] In the technical solution of the present invention, the maintenance box includes a box body and a box cover, a maintenance part for placing the electric pole is provided in the middle of the box body, a first mounting part and a second mounting part are provided on the left and right sides of the maintenance part, the first mounting part and the maintenance part are separated by a fixed bracket, the first mounting part and the corresponding side second mounting part are separated by a partition plate, the box cover is arranged above the maintenance part and the first mounting part, and the second mounting part is in a sealed state.

[0016] This setting ensures that after the box cover is closed, the maintenance part and the first installation part are in a sealed state, and the second installation part is also 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 that is convenient for placing the electric pole. The top surface of the bracket is provided with a plurality of balls regularly arranged along the top surface. The balls are embedded in the top surface of the bracket and can rotate freely. A blocking rod is fixed symmetrically in the front and back in the middle of the outer side wall of the bracket.

[0018] In this setting, the ball bearings reduce the friction between the pole and the bracket when it rotates, preventing the pole from being damaged when it is not fully formed. The barrier rod can prevent the pole from shaking left and right, which would cause the abutment structure to be unable to be completely fixed to the pole.

[0019] In the technical solution of the present invention, the first motor is fixed on the outer 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 sliding of the limiting structure is provided on the fixed rod on the right side, and a socket is provided on the outer side of the fixed cylinder wall on the right side.

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

[0021] In the technical solution of the present invention, the limiting structure includes a movable ring mounted on the fixed rod on the right side, an insertion rod symmetrically fixed on the front ring wall of the movable ring, 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 movable rod on the right side, the connecting rod passes through the slide groove, the middle part of the connecting rod is in the shape of a circular plate, the slide groove is adapted to the shape of the connecting rod, and a second spring is provided between the outer side of the middle part of the slide groove and the connecting rod.

[0022] In this setting, the abutment structure on the right side is blocked when it moves to the right blocking rod, and the anti-slip pad on the right side continues to move toward the middle. The blocking rod blocks the movable ring and drives the insertion rod to withdraw from the slot and the socket, thereby releasing the movable rod, so that the anti-slip pad is tightly fixed to the inner wall of the pole. By setting a second spring, the insertion rod can be pushed to reset when maintenance is completed, which is convenient for next use.

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

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

[0025] In this arrangement, 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 toward the middle. Due to the presence of the clamping ring, the abutting structures on both sides will be driven to move relatively toward the middle.

[0026] In the technical solution of the present invention, the transmission structure includes a second rotating rod whose left end is rotatably connected to the second mounting part on the left side near the left inner wall, a driven tooth coaxially fixed to the right end of the second rotating rod, and a third rotating rod parallel to the outside of the second rotating rod. The second rotating rod and the third rotating rod on the corresponding side are transmitted through a crawler track. A driving tooth is coaxially fixed to the left end of the rotating drum, and the driving tooth and the driven tooth engage with the steam nozzle.

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

[0028] In this setting, when the drum rotates, the active teeth will synchronously drive the second rotating rods on both sides to rotate through the driven teeth on both sides, and then drive the third rotating rods on both sides to rotate through the crawler tracks. At this time, the steam nozzle will slide back and forth along the first limit groove to spray steam toward the pole.

[0029] On the other hand, 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:

[0030] S1. Hoist the pole after static shaping into the maintenance department, place the end with larger diameter on the left bracket and the end with smaller diameter 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 toward the middle, and the left abutment structure extends from the middle of the left side of the pole until the anti-slip pad is completely in close contact with the inner wall of the pole;

[0032] S3. When the right abutment structure moves to the right blocking rod, the right anti-slip pad has completely entered the middle of the right side of the pole. After continuing to move toward the middle, the blocking rod will block the movable ring and drive the plug rod out of the slot and the socket, thereby releasing the movable rod, so that the first spring pushes the anti-slip pad to completely adhere to the inner wall of the pole, turning off the second motor;

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

[0034] S5. As the drum rotates, 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 belt. At this time, the steam nozzle will reciprocate along the first limiting 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 is pressed back into the fixed tube because 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 continues to move to the right, the movable rod continues to be pressed back into the fixed tube until the slot is exposed. 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-slip pad is completely in close contact with the inner wall of the pole; when the abutment structure on the right moves to the right stop rod, the anti-slip pad on the right has completely entered the middle part of the right side of the pole. After continuing to move toward the middle, the stop 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-slip pad to completely in close contact with the inner wall of the pole so that the pole is fixed. 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 rotate back and forth, so that the pole can be evenly in contact with the steam, thereby improving the maintenance effect.

[0038] 2. In the present invention, by setting up a steam component, while the drum rotates, the active teeth will synchronously drive the second rotating rods on both sides to rotate through the driven teeth on both sides, and then drive the third rotating rods on both sides to rotate through the crawler tracks. At this time, the steam nozzle will slide back and forth along the first limiting groove to spray steam toward the pole, so that the steam spraying point is not fixed, avoiding the situation of local excessive temperature during maintenance. At the same time, since the steam nozzle can be movable, the device greatly reduces the use of the steam nozzle, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0056] Unless expressly stated otherwise, throughout the specification, the term “comprise” or variations thereof such as “include” or “comprising” will be understood to include the stated elements or components but not to exclude other elements or components.

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

[0058] The maintenance equipment and method for the production of prestressed electric poles based on low-carbon materials include a maintenance box 1, a movable component 2 for driving the electric pole to rotate is provided in the maintenance box 1, and a steam component 3 for releasing steam is provided in the maintenance part 13. By providing the movable component 2 to drive the electric pole to rotate, the electric pole is more evenly contacted with the steam during maintenance. By providing the steam component 3, the steam ejection point is not fixed during the maintenance of the electric pole, and the steam can be ejected more evenly, thereby avoiding local excessive temperature and affecting the maintenance effect.

[0059] The movable assembly 2 includes an abutment structure 22, two symmetrically arranged rotating structures 21 for driving the abutment structure 22 to rotate, and a translation structure 24 for driving the abutment structure 22 to move left and right. The two symmetrically arranged abutment structures 22 are used to fix the pole so that the pole rotates synchronously with the rotating structures 21 during maintenance. The translation structure 24 is provided to adjust the position of the abutment structure 22 to prevent the abutment structure 22 from affecting the placement and removal of the pole.

[0060] The rotating structure 21 includes a first motor 211, a rotating drum 212 coaxially fixed to the output shaft of the first motor 211, and a transmission rod 214 slidably connected to the rotating drum 212. The outer wall of the transmission rod 214 is symmetrically provided with outwardly protruding flanges 215 in front and back. The inner end of the transmission rod 214 is coaxially fixed with a fixing rod 25, and the inner end of the fixing rod 25 is symmetrically provided with fixing cylinders 251 in upper and lower directions. During maintenance, the first motor 211 drives the rotating drum 212 to rotate, and the flange 215 drives the transmission rod 214 and the fixing rod 25 to rotate, thereby driving the pole to reciprocate.

[0061] The abutment structure 22 includes two vertically symmetrical movable rods 221 and an anti-slip pad 222 fixedly connected to the outer end of the movable rod 221. The inner end of the movable rod 221 is slidably connected to the corresponding fixed cylinder 251. A first spring 223 is provided 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 extension of the right abutment structure 22 is provided on the right fixed rod 25. When the abutment structure 22 enters the interior of the pole, since the diameter of the pole gradually decreases from left to right, the anti-slip pad 222 will cling to the inner wall of the pole under the action of the first spring 223, thereby fixing the pole by friction.

[0062] The steam component 3 includes two transmission structures 31 symmetrically arranged on both sides of the left rotating structure 21. The two transmission structures 31 are staggered with steam nozzles 32. During maintenance, the transmission structure 31 will drive the steam nozzle 32 to slide back and forth, thereby changing the steam ejection point, avoiding the local temperature being too high during maintenance due to the fixed ejection point.

[0063] In addition, if Figures 1-4 As shown, the maintenance box 1 includes a box body 11 and a box cover 12. A maintenance portion 13 for placing an electric pole is provided in the middle of the box body 11. A first mounting portion 14 and a second mounting portion 15 are provided on both sides of the maintenance portion 13. The first mounting portion 14 and the maintenance portion 13 are separated by a fixed bracket 16, and the first mounting portion 14 and the second mounting portion 15 on the corresponding side are separated by a partition plate. The first mounting portion 14 is provided for the abutment structure 22 to slide left and right. The box cover 12 is provided above the maintenance portion 13 and the first mounting portion 14 to ensure that when in use, the maintenance portion 13 and the first mounting portion 14 are in a sealed state, and the second mounting portion 15 is always in a sealed state.

[0064] Furthermore, the top surface of the bracket 16 is an arc-shaped concave surface for placing the electric pole. The top surface of the bracket 16 is provided with a plurality of balls 17 regularly arranged along the top surface. 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, thereby avoiding damage to the electric pole when it is not fully formed. A baffle 18 is fixed symmetrically in the front and back of the middle of the outer wall of the bracket 16. The baffle 18 can prevent the electric pole from shaking left and right, which causes the abutment structure 22 to be unable to be completely fixed to the electric pole.

[0065] In addition, if Figure 5-Figure 9 As shown, the first motor 211 is fixed on the outer inner wall of the corresponding 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, and a sliding cavity 213 is provided in the rotating cylinder 212 for the transmission rod 214 to slide. The rotating cylinder 212 is driven to rotate by the first motor 211, and then the transmission rod 214 is driven to rotate. At the same time, since the transmission rod 214 is slidably connected to the rotating cylinder 212, the translation structure 24 will not be blocked by the rotating cylinder 212 when driving the abutment structure 22. A sliding groove 253 for limiting the sliding of the structure 26 is provided on the right fixed rod 25, and a socket 252 is provided on the wall of the right fixed cylinder 251 facing outward.

[0066] Furthermore, the limiting structure 26 includes a movable ring 261 sleeved on the right fixed rod 25, an insertion rod 262 symmetrically fixed on the front ring wall of the movable ring 261, 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 slide 253. The middle part of the connecting rod 263 is in the shape of a circular plate. The slide 253 is adapted to the shape of the connecting rod 263. When fixing the pole, the abutting structure 22 on the right side will be blocked when it moves to the right blocking rod 18. The anti-slip pad 222 on the right side has fully entered the middle of the right side of the pole. After continuing to move toward the middle, the blocking rod 18 will block the movable ring 261 and drive the insertion rod 262 to withdraw from the slot 23 and the socket 252, thereby releasing the movable rod 221. It should be noted that when not in use, the abutment structure 22 on the right side can enter from the opening at the right end of the pole without being blocked by the pole. A second spring 264 is provided between the outer side of the middle part of the slide groove 253 and the connecting rod 263. By setting the second spring 264, the insertion rod 262 can be pushed to reset when maintenance is completed, which is convenient for next use.

[0067] In addition, if Figure 10 As shown, the translation structure 24 includes a second motor 241 fixed to 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 side fixed rods 25. The connecting mechanism 244 includes a base rod 2441 and a snap ring 2442 fixed to the base rod 2441. The snap ring 2442 is embedded in the rod wall of the corresponding fixed rod 25. The snap ring 2442 does not affect the rotation of the fixed rod 25 but can drive the fixed rod 25 to move left and right.

[0068] A second limiting groove 141 is provided in the middle of the bottom surface of the first mounting portion 14 for the connecting mechanism 244 to slide left and right. The second limiting groove 141 limits the connecting mechanism 244 to prevent the connecting mechanism 244 from rotating in the vertical plane. A threaded portion 243 is provided on the wall of the first rotating rod 242 corresponding to the second limiting groove 141, and the thread directions of the left and right threaded portions 243 are opposite, ensuring that the left and right connecting mechanisms 244 move in opposite directions. During maintenance, the second motor 241 drives the first rotating rod 242 to rotate, so that the threaded portion 243 drives the base rod 2441 and the snap ring 2442 to move synchronously toward the middle. Due to the existence of the snap ring 2442, the abutment structures 22 on both sides will be driven to move relatively toward the middle.

[0069] Furthermore, if Figure 11-12 When the second rotating rod 311 rotates, the third rotating rod 314 is driven by the third rotating rod 314 and the third rotating rod 314 is driven by the third rotating rod 314.

[0070] Specifically, the front and rear side walls of the maintenance portion 13 are symmetrically provided with first limiting grooves 131, the outer end of the base of the steam nozzle 32 is embedded in the corresponding first limiting groove 131 and the steam nozzle 32 is slidably connected to the corresponding first limiting groove 131, and the steam nozzle 32 is limited by setting the first limiting groove 131 to prevent the steam nozzle 32 from rotating with the third rotating rod 314. The steam nozzle 32 is provided with a metal bellows 33, a retractable metal bellows 33, which can prevent the steam nozzle 32 from being blocked by the pipe when sliding left and right. One end of the metal bellows 33 is connected to the corresponding steam nozzle 32. The nozzle 32 is connected, and the other end is connected to a steam pipe 34. The steam pipe 34 passes through the front wall of the second mounting portion 15 on the right side and is connected to an external steam generating device. When the rotating drum 212 rotates, the active 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 313. At this time, the steam nozzle 32 will slide back and forth along the first limiting groove 131 to spray steam toward the pole. It should be noted that the steam generating device is a commonly used existing technology in this field and will not be described here.

[0071] The present invention also provides a maintenance method for prestressed pole production based on low-carbon materials, which uses the above-mentioned maintenance equipment for prestressed pole production based on low-carbon materials, including 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;

[0073] S2. 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 abutment structure 22 moves to the right blocking rod 18, the right anti-slip pad 222 has completely entered the middle of the right side of the pole. After continuing to move toward the middle, the blocking rod 18 will block the movable ring 261 and drive the insertion rod 262 to withdraw from the slot 23 and the insertion hole 252, thereby releasing the movable rod 221, so that the first spring 223 pushes the anti-slip pad 222 to completely adhere to the inner wall of the pole, turning off the second motor 241.

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

[0076] S5. As the drum 212 rotates, the driving gear 27 synchronously drives the second rotating rods 311 on both sides to rotate through the driven gears 312 on both sides, and then drives 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 abutting structures 22 on both sides to move outward. The abutting structure 22 on the left 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 the movable rod 221. As the right abutting structure 22 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.

Hoist the pole after static shaping into the maintenance department, place the end with larger diameter on the left bracket and the end with smaller diameter on the right bracket, and close the box cover after placement; 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 toward the middle, and the left abutment structure extends from the middle of the left side of the pole until the anti-slip pad is completely in close contact with the inner wall of the pole; S3. When the right abutment structure moves to the right blocking rod, the right anti-slip pad has completely entered the middle of the right side of the pole. After continuing to move toward the middle, the blocking rod will block the movable ring and drive the plug rod out of the slot and the socket, thereby releasing the movable rod, so that the first spring pushes the anti-slip pad to completely adhere to the inner wall of the pole, turning off the second motor; S4. After the pole is fixed, the external steam generating device and the first motor are started simultaneously to drive the rotating drum to rotate, and the driving rod and the fixing rod are driven to rotate under the action of the flange, thereby driving the pole to reciprocate; S5. As the drum rotates, 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 belt. At this time, the steam nozzle will reciprocate along the first limiting groove to spray steam toward the pole; 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 is pressed back into the fixed tube because 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.
