Description

Technical Field

[0001] This invention relates to the field of concrete product manufacturing technology, specifically to an energy-saving, low-energy-consumption, high-temperature curing device and its maintenance method for improving the crack resistance of cement poles. Background Technology

[0002] The high-temperature curing device for cement poles is a core process equipment in the concrete pole production system, determining production efficiency and the mechanical properties of the finished product. The industry mainstream uses an atmospheric pressure steam curing tank as the main structure. By introducing saturated steam into a sealed tank cavity, the latent heat released by steam condensation provides a stable high-temperature and high-humidity curing environment for the molded poles, accelerating the cement hydration reaction process. This compresses the strength gain period required for natural curing of concrete, which typically takes several weeks, to just over ten hours, making it a crucial link supporting the large-scale mass production of poles. Currently, domestic pole manufacturers generally adopt a batch-intermittent operation mode: after the molded poles produced in the centrifugal molding process accumulate to a whole batch (usually 4 sets or more), they are hoisted and stacked one by one into the support station within the steam curing tank using a bridge crane. After all workpieces are loaded, the insulated tank cover is closed, and four standard curing stages are sequentially executed: static stop, heating, constant temperature, and cooling. After the curing cycle is completed, the tank cover is fully opened again, and the finished molded poles are hoisted out one by one. The next batch of materials is then loaded, and production is organized in this cycle. This operation mode has significant energy efficiency shortcomings: the pool cover is completely open during the loading and unloading stage, and it usually takes 20 to 30 minutes to complete the hoisting operation of 4 sets of poles at a time. During this period, the high-temperature saturated steam and hot air remaining in the pool cavity are rapidly convected and overflowed through the large-area opening, while the outside room-temperature cold air continuously invades and is heated by the heat stored in the pool body, resulting in continuous heat dissipation. This includes both the latent heat loss released by the phase change of saturated steam and the sensible heat loss of the air and pool structure in the pool. In addition, after the cold workpieces are concentrated and batched into the pool, the temperature in the pool drops sharply in a short period of time. The temperature change rate fluctuates greatly in the early stage of the heating stage, which can easily cause thermal shock damage to the concrete matrix that has not yet reached its initial strength, destroying the continuity of the internal hydration structure. Ultimately, this manifests as insufficient crack resistance and large quality dispersion of the finished poles. Therefore, this invention provides an energy-saving, low-energy-consumption, high-temperature curing device and its maintenance method to improve the crack resistance of cement poles. Summary of the Invention

[0003] The purpose of this invention is to provide an energy-saving, low-energy-consumption, high-temperature curing device and its maintenance method for improving the crack resistance of cement poles, so as to solve the problems mentioned in the background art.

[0004] The technical solution of this invention is: an energy-saving, low-energy-consumption, high-temperature curing device for improving the crack resistance of cement poles, comprising an inclined base, two symmetrical inclined limiting slide rails fixedly installed on the top of the inclined base, an outer casing fixedly installed on the top of the inclined base, a plurality of C-shaped mounting brackets fixedly installed at equal intervals on the top of the outer casing, two symmetrical electric telescopic rods fixedly installed on the inner top of each C-shaped mounting bracket, a mounting top plate fixedly installed between the bottom telescopic ends of each pair of adjacent electric telescopic rods, and a chamber partition fixedly installed at the bottom of each mounting top plate. The device operates based on the principle of inclined multi-cavity step-by-step curing. Within the enclosed space formed by the inclined base and the outer casing, several equally spaced chamber partitions are arranged along the inclined surface to sequentially divide the workpiece into six functional chambers: a feeding chamber, a static stopping chamber, a heating chamber, a constant temperature chamber, a cooling chamber, and a discharging chamber. The entire device uses the gravity of the mold rod itself as the conveying driving force. Through the orderly lifting and closing of each chamber partition, the workpiece is moved step-by-step along the inclined track, and the core curing area maintains a relatively closed operating state throughout the process.

[0005] Preferably, a horizontal mounting plate is fixedly installed on the side wall of each chamber partition plate, a vertical mounting plate is fixedly installed at the bottom of each horizontal mounting plate, two symmetrical buffer slide rods are slidably arranged on the side wall of each vertical mounting plate, an arc-shaped buffer plate is fixedly installed between the upper sides of each pair of adjacent buffer slide rods, a bidirectional arc-shaped plate is fixedly installed between the lower sides of each pair of adjacent buffer slide rods, a buffer spring is wound around the body of each buffer slide rod, and several buffer springs are respectively connected between the corresponding arc-shaped buffer plate and the corresponding vertical mounting plate.

[0006] Preferably, each of the mounting horizontal plates has a limiting slide rail at its bottom, and each of the arc-shaped buffer plates has a limiting slider welded to its top, which is slidably disposed in the corresponding limiting slide rail. The centrifugally formed molded electric rod is hoisted to the loading cavity at the top of the inclined surface by an external bridge crane. During positioning, the outer circumference of the mold is embedded in the guide groove of the inclined limiting slide rail, completing the initial positioning. Each cavity is equipped with an electric telescopic rod and a mounting top plate at its top, and the cavity partition plate is rigidly connected to the mounting top plate. After the workpiece is positioned in the loading cavity, the electric telescopic rod drives the mounting top plate and the corresponding cavity partition plate to lift upwards, guiding... The material loading chamber and the static stopping chamber are connected by a channel. The mold rod rolls down the inclined limiting slide rail under its own weight and enters the static stopping chamber. The arc-shaped buffer plate on the inner side of the chamber contacts the outer wall of the mold. The rolling kinetic energy is absorbed by the compression deformation of the rear buffer spring, so that the workpiece can be smoothly decelerated and accurately stopped. Then, the initial solidification and static setting process at room temperature is completed in the static stopping chamber. After the static stopping process is completed, the partition plate corresponding to the static stopping chamber is raised synchronously to open the channel. The mold rod rolls into the heating chamber again by its own weight. In this way, the workpiece completes the heating, constant temperature and cooling curing stages in sequence and finally enters the unloading chamber.

[0007] Preferably, several strip-shaped mounting plates are welded at equal intervals between the two side walls of the inner cavity of the outer casing. Each strip-shaped mounting plate has two symmetrical limiting protrusions fixedly installed on its side wall. During the core curing stages such as heating, constant temperature, and cooling, the internal rods of the mold will undergo slight volume deformation due to the cement hydration reaction, resulting in a slight deformation of the steel mold. This may cause the mold wheel rim to jam against the oblique limiting slide rail side wall, leading to a fault where the workpiece cannot roll normally after the partition plate is raised. To address this fault, the back of the arc-shaped buffer plate in this device is fixed... A buffer slide bar is connected, and a bidirectional arc plate is installed at the end of the slide bar. During the lifting of the chamber partition plate, the bidirectional arc plate moves upward synchronously with the partition plate. Under the pushing action of the limiting protrusion, the bidirectional arc plate drives the buffer slide bar and the arc buffer plate to move slightly towards the direction of the mold rod, pushing the workpiece to lift slightly upward along the inclined plane, directly breaking the jamming state between the wheel rim and the slide rail. When the workpiece falls back, it gains initial kinetic energy under the action of gravity, and can smoothly pass through the original jamming position and roll downward. No manual intervention is required throughout the process, ensuring the reliability of gravity conveying.

[0008] Preferably, the inclined base has a main steam delivery pipe in its inner cavity, and each main steam delivery pipe is connected to several steam delivery branch pipes at equal intervals. Each steam delivery branch pipe is fixedly installed with a steam inlet valve. The top of the outer casing is connected to several exhaust pipes at equal intervals, and each exhaust pipe is fixedly installed with an exhaust valve.

[0009] Preferably, the inclined base has several strip-shaped drainage pipes evenly spaced downwards on its inclined surface. A main drainage pipe, communicating with these strip-shaped drainage pipes, is located inside the inclined base. The outlet of the main drainage pipe is connected to a condensate recovery pipe, and a drain valve is fixedly installed on the condensate recovery pipe. The high-temperature saturated steam required for curing is supplied by an external steam generator and delivered to the corresponding chambers via the main steam delivery pipe, branch steam delivery pipes, and steam inlet valves. During the heating phase, the steam inlet valve remains fully open while the exhaust valve is slightly open to rapidly increase the chamber temperature. During the constant temperature phase, the opening of the steam inlet valve is reduced to maintain a stable chamber temperature. During the cooling phase, the steam inlet valve is closed. The valve is gradually opened to achieve uniform cooling. After the steam comes into contact with the low-temperature mold and cavity wall, it condenses and releases heat. The resulting condensate drips down the cavity wall and mold surface, flows into the inclined surface of the base, and then flows by gravity into the corresponding strip drainage pipe. It then flows into the main drainage pipe and is finally discharged out of the device through the condensate recovery pipe and the drain valve, achieving automatic steam blocking and drainage. During the brief process of the partition plate on the side of the static stop cavity being raised and connected, a small amount of high-temperature steam in the heating cavity will overflow into the static stop cavity. This part of the waste heat can increase the ambient temperature of the static stop cavity, accelerate the initial setting process of concrete, shorten the static stop process time, and achieve spontaneous cascade utilization of waste heat.

[0010] Preferably, a side plate is fixedly installed on the horizontal end of the inclined base, and a plurality of transverse sliding rods are slidably arranged at equal intervals on the side plate. A horizontal limiting plate is fixedly installed between the plurality of transverse sliding rods. A horizontal limiting spring is wound around each transverse sliding rod, and the plurality of horizontal limiting springs are connected between the horizontal limiting plate and the side plate. A horizontal limiting plate and a horizontal limiting spring are provided at the end of the unloading cavity to form an elastic barrier for the rolling in molded electric rod, so as to achieve a smooth stop and wait for external lifting equipment to transfer the material out.

[0011] An energy-saving and low-energy-consumption curing method for improving the crack resistance of cement poles is disclosed. This method utilizes the aforementioned energy-saving and low-energy-consumption high-temperature curing device for improving the crack resistance of cement poles. Specifically, it includes the following steps: The centrifugally formed molded pole is hoisted by an external bridge crane to the loading chamber at the top of the inclined plane. During positioning, the outer circumference of the mold is embedded in the guide groove of the inclined limiting slide rail, completing the initial positioning. Each chamber is equipped with an electric telescopic rod and a mounting plate at its top, and the chamber partition plate is rigidly connected to the mounting plate. After the workpiece is positioned in the loading chamber, the electric telescopic rod drives the mounting plate and the corresponding chamber partition plate to rise, opening the passage between the loading chamber and the static stopping chamber. The molded pole, under its own weight... Under the action of the inclined limiting slide rail, the workpiece rolls downward and enters the static stopping cavity. The arc-shaped buffer plate on the inner side of the cavity contacts the outer wall of the mold. The rolling kinetic energy is absorbed by the compression deformation of the rear buffer spring, so as to achieve smooth deceleration and precise stopping of the workpiece. Then, the initial solidification and static setting process at room temperature is completed in the static stopping cavity. After the static stopping process is completed, the partition plate corresponding to the static stopping cavity is raised synchronously to open the conduction channel. The mold rod rolls into the heating cavity again by its own weight. In this way, the workpiece completes the heating, constant temperature and cooling curing stages in sequence and finally enters the unloading cavity. The end of the unloading cavity is equipped with a horizontal limiting plate and a horizontal limiting spring to form an elastic barrier for the rolling mold rod, so as to achieve smooth stopping and wait for external lifting equipment to transfer the material out.

[0012] This invention provides an energy-saving, low-energy-consumption, high-temperature curing device and its maintenance method for improving the crack resistance of cement poles. Compared with the prior art, it has the following improvements and advantages: 1. This device adopts a single-workpiece sequential entry mode. The entry of a single cold material only causes a slight drop in the temperature inside the cavity, with minimal fluctuation in the temperature change rate. This avoids severe thermal shock to the concrete during the initial setting period, ensuring the integrity of the internal hydration structure and improving the crack resistance and bearing capacity of the finished product. 2. The core high-temperature chamber in this device is centrally located to form a natural thermal buffer. There is no large-scale opening of the entire tank during the entire process. The workpiece is transferred by only slightly opening and closing the partition plates. Combined with gravity conveying and the cascade reuse of overflow steam waste heat, heat loss and overall energy consumption are significantly reduced.

[0013] 3. When the chamber partition plate in this device is raised, the linkage push structure is triggered simultaneously, which drives the arc-shaped buffer plate to lift the mold rod slightly upward, breaking the jamming between the mold wheel and the slide rail. The workpiece can then smoothly roll downward by gaining initial kinetic energy by its own weight. Attached Figure Description

[0016] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0017] This invention provides an energy-saving, low-energy-consumption, high-temperature curing device and its maintenance method for improving the crack resistance of cement poles. The technical solution of this invention is as follows: like Figures 1-10 As shown, an energy-saving, low-energy-consumption, high-temperature curing device for improving the crack resistance of cement poles includes an inclined base 1. Two symmetrical inclined limiting slide rails 2 are fixedly installed on the top of the inclined base 1. An outer casing 3 is fixedly installed on the top of the inclined base 1. Several C-shaped mounting brackets 4 are fixedly installed at equal intervals on the top of the outer casing 3. Two symmetrical electric telescopic rods 5 are fixedly installed on the top inner side of each C-shaped mounting bracket 4. A mounting top plate 6 is fixedly installed between the bottom telescopic ends of every two adjacent electric telescopic rods 5. A chamber partition plate 7 is fixedly installed at the bottom of each mounting top plate 6, and each chamber... All partition plates 7 are slidably connected to the top of the outer casing 3. This device operates based on the principle of inclined multi-cavity step-by-step curing. Within the enclosed space formed by the inclined base 1 and the outer casing 3, several equally spaced chamber partition plates 7 are arranged along the inclined surface to sequentially divide the material into six functional chambers: feeding chamber 31, static stopping chamber 32, heating chamber 33, constant temperature chamber 34, cooling chamber 35, and unloading chamber 36. The entire device uses the gravity of the mold rod 37 as the driving force for conveying. Through the orderly lifting and closing of each chamber partition plate 7, the workpiece is moved step-by-step along the inclined track, and the core curing area maintains a relatively closed operating state throughout the process.

[0018] Furthermore, a horizontal mounting plate 8 is fixedly installed on the side wall of each chamber partition plate 7, and a vertical mounting plate 9 is fixedly installed at the bottom of each horizontal mounting plate 8. Two symmetrical buffer slide rods 10 are slidably arranged on the side wall of each vertical mounting plate 9. An arc-shaped buffer plate 11 is fixedly installed between the upper sides of each pair of adjacent buffer slide rods 10, and a bidirectional arc-shaped plate 30 is fixedly installed between the lower sides of each pair of adjacent buffer slide rods 10. A buffer spring 12 is wound around the rod body of each buffer slide rod 10, and several buffer springs 12 are respectively connected to the corresponding arc-shaped buffer plate 11 and the corresponding vertical mounting plate 9. Each of the mounting horizontal plates 8 has a limiting slide rail 13 at its bottom, and each of the arc-shaped buffer plates 11 has a limiting slider 14 welded to its top, which is slidably disposed in the corresponding limiting slide rail 13. The centrifugally formed molded electric rod 37 is hoisted to the loading chamber 31 at the top of the inclined surface by an external bridge crane. During positioning, the outer circumference of the mold is embedded in the guide groove of the inclined limiting slide rail 2 to complete the initial positioning. Each chamber is equipped with an electric telescopic rod 5 and a mounting top plate 6 at its top, and the chamber partition plate 7 is rigidly connected to the mounting top plate 6. After the loading chamber 31 completes the workpiece positioning, the electric telescopic rod 5 drives the mounting top plate 6 and the corresponding chamber partition plate. 7. The upward lifting opens the channel between the feeding chamber 31 and the static stopping chamber 32; the mold-carrying electric rod 37 rolls downward along the inclined limiting slide rail 2 under its own gravity, and after entering the static stopping chamber 32, the arc-shaped buffer plate 11 on the inner side of the chamber contacts the outer wall of the mold, and absorbs the rolling kinetic energy through the compression deformation of the rear buffer spring 12, so as to achieve smooth deceleration and precise stopping of the workpiece, and then complete the initial solidification and static setting process at room temperature in the static stopping chamber 32; after the static stopping process is completed, the partition plate corresponding to the static stopping chamber 32 is raised synchronously to open the channel, and the mold-carrying electric rod 37 rolls again into the heating chamber 33 by its own weight; and so on, the workpiece sequentially completes the heating, constant temperature and cooling processes. After stage maintenance, it finally enters the unloading chamber 36; a side plate 26 is fixedly installed on the horizontal end of the inclined base 1, and a number of transverse sliding rods 27 are slidably arranged at equal intervals on the side plate 26. A horizontal limiting plate 28 is fixedly installed between the number of transverse sliding rods 27. A horizontal limiting spring 29 is wound around each transverse sliding rod 27, and the number of horizontal limiting springs 29 are connected between the horizontal limiting plate 28 and the side plate 26. The horizontal limiting plate 28 and the horizontal limiting spring 29 are set at the end of the unloading chamber 36 to form an elastic barrier for the rolling in molded electric rod 37, so as to achieve a smooth stop and wait for the external lifting equipment to transfer the material out.

[0019] Furthermore, several strip-shaped mounting plates 15 are welded at equal intervals between the two side walls of the inner cavity of the outer casing 3. Each strip-shaped mounting plate 15 has two symmetrical limiting protrusions 16 fixedly installed on its side wall. During the core curing stages such as heating, constant temperature, and cooling, the internal electric rod of the mold will undergo slight volume deformation due to the cement hydration reaction, resulting in a slight deformation of the steel mold. This may cause the mold wheel ring to jam against the side wall of the inclined limiting slide rail 2, resulting in a fault where the workpiece cannot roll normally after the partition plate is raised. To address this fault, the back of the arc-shaped buffer plate 11 in this device is fixedly connected to a buffer. The slide bar 10 has a bidirectional arc plate 30 at its end. During the lifting of the chamber partition plate 7, the bidirectional arc plate 30 moves upward synchronously with the partition plate. Under the pushing action of the limiting protrusion 16, the bidirectional arc plate 30 drives the buffer slide bar 10 and the arc buffer plate 11 to move slightly towards the mold rod 37, pushing the workpiece to lift slightly upward along the inclined surface, directly breaking the jamming state between the wheel rim and the slide rail. When the workpiece falls back, it gains initial kinetic energy under the action of gravity and can smoothly pass through the original jamming position and roll downward. No manual intervention is required throughout the process, ensuring the reliability of self-weight conveying.

[0020] Furthermore, the inclined base 1 has a steam delivery main pipe 17 inside its cavity, with several steam delivery branch pipes 18 connected at equal intervals to each main pipe 17. Each steam delivery branch pipe 18 is fixedly equipped with a steam inlet valve 19. The top of the outer casing 3 has several exhaust pipes 20 connected at equal intervals, with an exhaust valve 21 fixedly installed on each exhaust pipe 20. Several strip-shaped drainage pipes 22 are evenly spaced downwards on the inclined surface of the inclined base 1. A main drainage pipe 23, communicating with the strip-shaped drainage pipes 22, is located inside the inclined base 1. The outlet of the main drainage pipe 23 is connected to a condensate recovery pipe 24, with a drain valve 25 fixedly installed on the condensate recovery pipe 24. The high-temperature saturated steam required for curing is supplied by an external steam generator and sent to the corresponding cavity via the main steam delivery main pipe 17, each branch steam delivery pipe 18, and the steam inlet valve 19. During the heating phase, the steam inlet valve 19 is kept at a large opening and the exhaust valve 21 is slightly open to rapidly increase the temperature inside the cavity. During the constant temperature phase, the opening of the steam inlet valve 19 is reduced to maintain a stable temperature inside the cavity. During the cooling phase, the steam inlet valve 19 is closed and the exhaust valve 21 is gradually opened to achieve uniform cooling. After the steam comes into contact with the low-temperature mold and the cavity wall, it condenses and releases heat. The condensate formed drips down along the cavity wall and the surface of the mold, flows into the inclined surface of the inclined base 1, and then flows by gravity into the corresponding strip drainage pipe 22. It then flows into the main drainage pipe 23 and is finally discharged out of the device through the condensate recovery pipe 24 and the drain valve 25 to achieve automatic steam blocking and drainage. During the brief process of the partition plate on the side of the static stop cavity 32 being raised and connected, a small amount of high-temperature steam in the heating cavity 33 will overflow into the static stop cavity 32. This part of the waste heat can increase the ambient temperature of the static stop cavity 32, accelerate the initial setting process of concrete, shorten the static stop process time, and realize the spontaneous cascade utilization of waste heat.

[0021] Working principle: This device operates based on the principle of inclined multi-cavity step-by-step curing. Within the enclosed space formed by the inclined base 1 and the outer casing 3, six functional chambers are sequentially divided from top to bottom along the inclined surface by several equally spaced chamber partition plates 7: feeding chamber 31, static stopping chamber 32, heating chamber 33, constant temperature chamber 34, cooling chamber 35, and unloading chamber 36. The entire device uses the gravity of the mold rod 37 as the driving force for conveying. Through the orderly lifting and closing of each chamber partition plate 7, the workpiece is moved step-by-step along the inclined track, and the core curing area maintains a relatively closed operating state throughout the process. The centrifugally formed molded electric rod 37 is hoisted by an external bridge crane to the loading chamber 31 at the top of the inclined plane. During positioning, the outer circumference of the mold wheel is embedded in the guide groove of the inclined limiting slide rail 2, completing the initial positioning. Each chamber is equipped with an electric telescopic rod 5 and a mounting plate 6, and the chamber partition plate 7 is rigidly connected to the mounting plate 6. After the workpiece is positioned in the loading chamber 31, the electric telescopic rod 5 drives the mounting plate 6 and the corresponding chamber partition plate 7 to rise, opening the passage between the loading chamber 31 and the stationary chamber 32. 7. Under its own gravity, the workpiece rolls downward along the inclined limiting slide rail 2 and enters the static stopping cavity 32. The arc-shaped buffer plate 11 inside the cavity contacts the outer wall of the mold, absorbing the rolling kinetic energy through the compression deformation of the rear buffer spring 12, achieving smooth deceleration and precise stopping of the workpiece. Subsequently, it completes the initial solidification and static setting process at room temperature within the static stopping cavity 32. After the static stopping process, the partition plate corresponding to the static stopping cavity 32 synchronously lifts to open the conduction channel, and the mold-carrying electric rod 37 rolls again into the heating cavity 33 under its own weight. This process is repeated, and the workpiece sequentially completes the heating process... After curing at constant temperature and cooling stages, the material finally enters the unloading chamber 36. A horizontal limiting plate 28 and a horizontal limiting spring 29 are installed at the end of the unloading chamber 36 to provide elastic resistance to the rolling-in molded electric rod 37, ensuring a smooth stop and awaiting transfer by external lifting equipment. The high-temperature saturated steam required for curing is supplied by an external steam generator and delivered to the corresponding chambers via the main steam conveying pipe 17, branch steam conveying pipes 18, and steam inlet valves 19. During the heating stage, the steam inlet valve 19 remains fully open while the exhaust valve 21 is slightly open, rapidly lifting the chamber. Internal temperature; during the constant temperature stage, reduce the opening of the steam inlet valve 19 to maintain a stable internal temperature; during the cooling stage, close the steam inlet valve 19 and gradually open the exhaust valve 21 to achieve uniform cooling; after the steam contacts the low-temperature mold and the cavity wall, it condenses and releases heat, and the condensate formed drips down along the cavity wall and the mold surface, flows into the inclined surface of the inclined base 1, and then flows along the slope into the corresponding strip drainage pipe 22, and then gathers into the main drainage pipe 23, and finally is continuously discharged out of the device through the condensate recovery pipe 24 and the drain valve 25 to achieve automatic steam blocking and drainage; During the brief period when the partition plate on the side of the static stop chamber 32 is raised and connected, a small amount of high-temperature steam in the heating chamber 33 will overflow into the static stop chamber 32. This waste heat can raise the ambient temperature of the static stop chamber 32, accelerate the initial setting process of concrete, shorten the static stop process time, and realize the spontaneous cascade utilization of waste heat. The core high-temperature chambers such as the heating chamber 33, the constant temperature chamber 34, and the cooling chamber 35 in this device are concentrated in the middle of the device, and the two ends are formed by low-temperature chambers to form a natural thermal buffer, which greatly reduces the rate of heat loss from the core area. At the same time, there is no large-scale opening of the entire pool during the entire process, and it is only achieved by opening and closing the partition plate in a small range. The workpiece flow significantly reduces convective heat loss and latent heat loss, resulting in a substantial reduction in overall energy consumption. This device employs a single-workpiece sequential feeding mode, where the entry of a single cold workpiece causes only a slight drop in cavity temperature with minimal temperature fluctuations. This avoids the severe thermal shock caused by batches of cold material entering the tank, effectively protecting the integrity of the hydration structure of the concrete matrix during the initial setting period and improving the crack resistance and quality stability of the finished poles. This device can be directly connected to existing centrifugal molding processes and subsequent demolding processes, eliminating the need for replacement or modification of existing lifting equipment and grippers. This results in low production line modification costs and strong adaptability. During the core curing stages such as heating, constant temperature, and cooling, the internal electric rods of the mold will undergo slight volume deformation due to the cement hydration reaction, resulting in slight deformation of the steel mold. This may cause the mold wheel rim to jam against the side wall of the inclined limiting slide rail 2, leading to a fault where the workpiece cannot roll normally after the partition plate is raised. To address this fault, the back of the arc-shaped buffer plate 11 in this device is fixed to the buffer slide rod 10, and a bidirectional arc plate 30 is set at the end of the slide rod. During the lifting of the chamber partition plate 7, the bidirectional arc plate 30 moves upward synchronously with the partition plate. Under the pushing action of the limiting protrusion 16, the bidirectional arc plate 30 drives the buffer slide rod 10 and the arc-shaped buffer plate 11 to move slightly towards the mold electric rod 37, pushing the workpiece to lift slightly upward along the inclined surface, directly breaking the jamming state between the wheel rim and the slide rail. When the workpiece falls back, it gains initial kinetic energy under the action of gravity and can smoothly roll downward through the original jamming position. No manual intervention is required throughout the process, ensuring the reliability of self-weight conveying.

8. An energy-saving and low-energy-consumption maintenance method for improving the crack resistance of cement poles, characterized in that: This method of use employs an energy-saving, low-energy-consumption, high-temperature curing device for improving the crack resistance of cement poles as described in claim 7, specifically including the following steps: The centrifugally formed molded pole (37) is hoisted by an external bridge crane to the loading chamber (31) at the top of the inclined surface. During positioning, the outer circumference of the mold is embedded in the guide groove of the inclined limiting slide rail (2) to complete the initial positioning; each chamber is equipped with an electric telescopic rod (5) and a mounting plate (6) at the top, and the chamber partition plate (7) is rigidly connected to the mounting plate (6); after the workpiece is positioned in the loading chamber (31), the electric telescopic rod (5) drives the mounting plate (6) and the corresponding chamber partition plate (7) to rise upward, opening the channel between the loading chamber (31) and the stationary chamber (32); the molded pole (37) moves along the inclined limiting slide rail (31) under its own gravity. 2) After rolling downwards and entering the static stop cavity (32), the arc-shaped buffer plate (11) on the inner side of the cavity contacts the outer wall of the mold. The rolling kinetic energy is absorbed by the compression deformation of the rear buffer spring (12), so as to achieve smooth deceleration and precise stopping of the workpiece. Then, the initial solidification and static setting process at room temperature is completed in the static stop cavity (32). After the static stop process is completed, the partition plate corresponding to the static stop cavity (32) is raised synchronously to open the conduction channel. The mold rod (37) rolls into the heating cavity (33) again by its own weight. In this way, the workpiece completes the heating, constant temperature and cooling stages of curing in sequence, and finally enters the unloading cavity (36). The unloading cavity (36) is equipped with a horizontal limit plate (28) and a horizontal limit spring (29) at the end to form an elastic barrier for the rolling mold rod (37) to achieve smooth stopping and wait for the external lifting equipment to transfer the material.
