Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cement pole manufacturing, in particular to an energy-saving type prefabricated cement pole manufacturing equipment and method. BACKGROUND

[0002] In the field of infrastructure construction, as a key supporting component for power transmission and communication network construction, the manufacturing quality of cement poles is directly related to the stability and safety of power grid operation. Especially under the background of urbanization promotion and continuous growth of power demand, there are high standards and rigorous requirements for the production efficiency and product quality of cement poles.

[0003] At present, the manufacturing of prefabricated cement poles usually adopts the process means of centrifugal forming combined with steam curing. The mold filled with cement slurry is usually placed on a rotating system, and the mold chuck is driven to rotate by a driving support wheel, so that the cement slurry adheres to the inner wall of the mold to form a predetermined shape under the action of centrifugal force. Subsequently, the cement slurry is formed and dried by a steam curing device.

[0004] However, in actual operation, the distribution of the cement slurry initially filled into the mold is difficult to keep uniform, which causes the "line contact" between the traditional cylindrical support wheel and the flat chuck to appear component misalignment and pressure concentration during the rotation of the chuck and the mold driven by the support wheel. That is, if the uneven distribution of the cement slurry causes "uneven wear", the local contact stress will increase significantly, which will cause "peeling" on the surface of the support wheel and "chamfer wear" on the edge of the chuck. Such damage not only shortens the service life of the support wheel and the chuck, but also affects the forming precision of the cement pole and increases the probability of failure stop during production. At the same time, during the installation of the equipment and the placement of the mold, the influence of external factors is large. If the tightness of the bolts is inconsistent during equipment assembly, or the impact force generated when placing heavy molds, the connection between the chuck and the support wheel will often become loose. Once loose, the end of the mold will lose balance during rotation, causing "horn deformation" at both ends of the cement pole formed by centrifugal force. The above deformation will make the cement pole unable to meet the flange butt joint requirements of subsequent installation, greatly increasing the product rejection rate and rework rate, not only causing waste of raw materials such as cement and steel, but also prolonging the production cycle, increasing the production cost of enterprises, restricting the improvement of production efficiency, and being not conducive to the realization of energy saving and emission reduction. Moreover, ensuring the stability of the equipment operation state and the consistency of the product quality is a key link for the large-scale production of the prefabricated cement telegraph pole. Timely detecting the installation and connection problems between the supporting wheel and the chuck can effectively avoid the occurrence of subsequent production failures. However, in terms of the prior art, there is a lack of means for assisting in detecting the installation and connection state of the supporting wheel and the chuck, and potential problems such as loose connection and abnormal contact cannot be found in time before or during production. Usually, the problems such as peeling of the supporting wheel, wear of the chuck or deformation of the telegraph pole cannot be detected until the problems occur, which has caused certain economic losses and production delay, and it is difficult to realize the prospective control of the production process.

[0005] In summary, the current prefabricated cement telegraph pole manufacturing equipment has many problems to be solved in terms of operation stability, product quality control and installation state detection, and it is urgent to develop an energy-saving prefabricated cement telegraph pole manufacturing equipment which can ensure the stable operation between the mold chuck and the driving supporting wheel, prevent the occurrence of eccentric wear, and assist in detecting the installation and connection problems between the supporting wheel and the chuck, so as to improve the production efficiency and product quality, reduce the production cost, and meet the demand for high-quality cement telegraph poles in infrastructure construction.

[0006] Therefore, the present application proposes an energy-saving prefabricated cement telegraph pole manufacturing equipment and method to solve the above problems. SUMMARY

[0007] Therefore, the present application proposes an energy-saving prefabricated cement telegraph pole manufacturing equipment and method to solve the above problems.

[0008] To achieve the above-mentioned purpose, the present application provides the following technical scheme: an energy-saving prefabricated cement telegraph pole manufacturing equipment, comprising: a foundation, further comprising: a safety protection group, a manufacturing group, a misplacement eccentric wear prevention group and a stability maintenance group; The safety protection group and the manufacturing group are fixedly connected to the upper surface of the foundation, the manufacturing group is covered by the safety protection group, and the misplacement eccentric wear prevention group and the stability maintenance group are arranged on the manufacturing group; The safety protection group is used for safety protection for relevant personnel when the manufacturing group is working; The manufacturing group is used for manufacturing the cement telegraph pole through centrifugal rotation; The misplacement eccentric wear prevention group is used for limiting the position of the components during centrifugal rotation of the equipment, and ensuring uniform distribution of the cement in the centrifugal state; The stability maintenance group is used for adding stable points to the limiting of the misplacement eccentric wear prevention group, and ensuring the perfection of the work of the misplacement eccentric wear prevention group.

[0009] Preferably, the safety protection group comprises side plate walls fixedly connected to the upper surface of the foundation, and the side plate walls are symmetrically distributed; The top of the side plate wall inner cavity is provided with an opening and closing shaft, and a folding plate is fixedly connected to the opening and closing shaft.

[0010] As preferred, the manufacturing group comprises a support frame fixedly connected to the foundation, a driving shaft rod transversely inserted into the support frame, and a supporting wheel A fixedly connected to the driving shaft rod.

[0011] As preferred, a mold is supported between the two supporting wheels A, and reinforcing ribs are fixedly connected to the mold at equal intervals. A chuck A is fixedly connected to the reinforcing rib, and a bottom plate is inserted into the two ends of the mold.

[0012] As preferred, the anti-misplacement and eccentric wear group comprises a supporting wheel B fixedly connected to the driving shaft rod, an adhering piece sleeved on the driving shaft rod, a fastener threadedly connected to the adhering piece, a disc fixedly connected to the driving shaft rod, and a screw hole adapted to the fastener formed in the disc, wherein the supporting wheel B is located between the disc and the adhering piece.

[0013] As preferred, a ring strip ring is fixedly connected to the outer ring surface of the supporting wheel B, the cross section of the ring strip ring is trapezoidal, and wave grooves are formed in the outer periphery of the ring strip ring at equal intervals. A chuck B is fixedly connected to the mold, and a ring groove is formed in the outer periphery of the chuck B.

[0014] As preferred, the stability maintenance group comprises cylindrical grooves formed in the supporting wheel B at equal intervals, springs fixedly connected to the cylindrical grooves, centrifugal blocks fixedly connected to the top ends of the springs, hole grooves formed in the outer periphery of the chuck B at equal intervals, and the hole grooves symmetrically distributed on both sides of the ring groove; the centrifugal blocks are designed in a conical shape and are adapted to the hole grooves.

[0015] Further technical solutions: an energy-saving prefabricated cement pole manufacturing method comprises the following steps: Step one: framework manufacturing stage Steel pretreatment: PC steel is straightened by a straightening machine and then cut into a fixed size; meanwhile, reinforcing steel bars are prepared for subsequent bundling and reinforcement; Outer layer steel frame bundling: every 20 cut PC steel bars form a group, which is conveyed to a bundling machine by a caterpillar belt; the reinforcing steel bars are spot-welded on the ring-shaped steel frame to enhance plasticity, and the standard outer layer steel frame is formed by pulling out from the other end by a traction machine, and workers manually reinforce the bundling at both ends; Inner layer steel frame manufacturing: steel bars are cut and moved to an operating position, a ring-shaped fixer is inserted into the steel bars to ensure consistent spacing between the steel bars; the steel bars are inserted into a traction machine at the passing end, and a traction table is moved to support the steel bars below the fixing disc to form an inner layer steel frame; Double-layer steel frame assembly: workers pull the inner layer steel frame to the outer layer steel frame platform, two workers cooperate to move the outer layer steel frame to the track, start the electric traction machine, and make the inner layer steel frame pass through the outer layer steel frame; form a closed opening at one end with a fixed ring, connect a fixed disc at the other end, pass in a steel rod to make the whole hollow, and finally completely tie and fix with fine steel wire, complete the prefabricated steel frame; Step two: mold preparation and assembly stage Mold pretreatment: the concrete pouring mold is made of steel material, the inside is sprayed with high-temperature ceramic particles, the mold shell is heated and sprayed with oil first; Steel frame and mold assembly: put the prefabricated steel frame into the pouring shell, i.e. the mold, through mechanical hooks, confirm that there is no error, and then perform fastening operation to ensure complete closure; Mold anti-misalignment and wear assembly: fix chuck B on the mold, and open ring groove and hole groove on the outer periphery of the chuck B circular ring; align the carrier wheel B on the drive shaft with the chuck B, make the ring strip ring of the outer ring surface of the carrier wheel B enter the ring groove of the chuck B, and at the same time, fix the carrier wheel B between the circular pieces of the drive shaft through the attached pieces and fasteners, complete the anti-misalignment and wear structure assembly; add lubricating oil in advance in the wave groove of the ring strip ring to reduce the dry friction between the carrier wheel B and the chuck B.

[0016] Step three: concrete preparation and pouring stage Concrete preparation: the truck pours the concrete stone through the ground delivery port, the stone is filtered out of large stones by the screen, and is sent to the top of the concrete processing tank by the conveyor belt; the processing tank automatically releases cement ash and water, adjusts according to the set proportion, and mixes and stirs until completely uniform; Concrete pouring: the automatic transport table sends the concrete grouting pipe into the deepest part of the pouring shell mold, the grouting pipe swings to pour concrete, while slowly withdrawing at a fixed uniform speed to ensure sufficient pouring and internal grouting volume; before pouring, check the hidden troubles such as fastener loosening and component displacement through the clamping state of the ring strip ring and the ring groove, the pre-alignment gap between the centrifugal block on the carrier wheel B and the hole groove of the chuck B, and ensure the installation accuracy of the mold; Step four: shaping and solidification stage Safety protection starts: start the safety protection group, the folding plate rotates around the opening and closing shaft as the axis, the safety protection mode starts, and the material splashing in the shaping process is avoided; Centrifugal rotation shaping: start the drive shaft rod to drive the carrier wheel A and the carrier wheel B to rotate synchronously, the carrier wheel A drives the mold through static friction with the chuck A, and the carrier wheel B drives the mold through the cooperation of the ring strip ring and the ring groove; the "automatic centering contact" of the ring strip ring and the ring groove replaces the traditional "line contact", disperses the misalignment contact pressure, avoids the peeling of the carrier wheel and the wear of the chuck, and ensures the stable rotation of the mold; During the rotation of the mold, the centrifugal block in the cylindrical groove of the support roller B moves outward under the action of centrifugal force and is embedded in the hole groove of the chuck B, forming a "multi-point fixing system" with the ring ring to offset the radial offset force of the mold and prevent the "flared mouth deformation" caused by the imbalance of force at the mold end; at the same time, the lubricating oil on the trapezoidal surface of the ring ring and the wave groove maintains a stable oil film, reducing dry friction damage between the support roller and the chuck. After the high-speed rotation ends, excess water is drained from the concrete, allowing it to adhere to the inner wall of the mold and form a hollow shape, while simultaneously completing the initial setting and hardening. After the rotation stops, workers use tools to remove the bottom plate of the mold, allowing any remaining water inside to drain out naturally. Accelerated curing and drying: The hoisting machine places the pouring mold into the drying chamber, and then it is dried to ensure that the concrete is completely cured and formed.

[0017] Step 5: Demolding and Post-processing Stage Demolding process: After drying, the machine removes all the screws from the outer mold, and the operator remotely controls the crane to remove the outer mold shell; the finished utility pole is then picked up with a high-pressure suction cup and placed on the conveyor belt; Finished product cleaning and labeling: Workers carefully tap the rings securing the steel rods at the base of the utility poles with hammers to remove any attached cement blocks; key information is then printed on the utility poles using a special stamp. Factory inspection: Before leaving the factory, staff use flashlights to inspect the surface of the utility pole, checking for cracks, gaps and other defects. They also confirm that there is no "flared mouth deformation" at the end to ensure that the finished product meets the flange connection requirements and finally completes the qualified product to leave the factory.

[0018] Compared with the prior art, the present invention provides an energy-saving precast concrete pole manufacturing equipment and method, which has the following beneficial effects: 1. This invention, through the design of an anti-misalignment and anti-wear assembly, can bring the following benefits when working in conjunction with the manufacturing assembly: Extending the service life of core components and reducing equipment maintenance costs: Based on the existing "line contact" state between roller A and chuck A, the anti-misalignment and wear assembly transforms the "line contact" between roller B and chuck B into "self-aligning contact" through the cooperation of the ring bar and the ring groove, fundamentally improving the contact state between the roller and chuck. Under the traditional "line contact" condition, uneven distribution of cement slurry easily leads to misalignment and wear, causing local contact stress to double, which in turn causes "stripping" on the roller surface and "chamfering wear" on the chuck edge. Such damage significantly shortens the replacement cycle of rollers and chucks, increasing the manpower and material costs of equipment maintenance. "Self-aligning contact" can disperse the misalignment contact pressure through the adaptive cooperation of the ring bar and the ring groove, avoiding stress concentration, effectively reducing failures such as roller stripping and chuck wear, significantly extending the service life of rollers and chucks, reducing the replacement frequency of core components, and thus reducing equipment maintenance costs and downtime for repairs. Stability of the mold rotation is directly related to the efficiency of the cement pole forming and the smoothness of the production process. The traditional "line contact" is prone to wear and tear, which can lead to a decrease in the precision of the supporting wheel and chuck. The mold may shake or jam during rotation, which not only affects the uniform distribution of the cement slurry but also often causes equipment failure and production interruption. The "automatic centering contact" design can adjust the stability of the components through the cooperation of the ring strip ring and the ring groove. Even if the initial distribution of the cement slurry is uneven, the supporting wheel and chuck can still maintain a stable contact state, avoiding abnormal mold rotation caused by wear and tear. This ensures the continuous and stable operation of the centrifugal forming process, avoids equipment downtime and maintenance, and improves the overall production efficiency.

[0019] 2. In addition to avoiding the misalignment of the supporting wheel B and the chuck B, the ring strip ring and the ring groove in the present application can also bring the following benefits: Pre-installation detection to avoid hidden loosening problems: The ring strip ring provides an intuitive and convenient carrier for the installation state detection of the chuck and the supporting wheel. Especially during the pre-alignment of the centrifugal block and the hole slot before work, the staff can use the cooperation of the ring strip ring and the two to clearly observe whether there is a component loosening problem. After the installation of the traditional equipment, the bolts are not tight, and the chuck or supporting wheel is loose due to external forces. These hidden problems are often discovered indirectly through mold rotation abnormalities or product defects after the equipment is running, which has caused equipment wear or production waste. Through the auxiliary detection of the ring strip ring, these hidden problems can be actively detected before installation or work, such as observing whether the ring strip ring on the supporting wheel B and the ring groove on the chuck B are evenly matched, and whether there is a shift gap when the centrifugal block and the hole slot are pre-aligned. This can quickly determine whether the fastener is loose and whether the component has been displaced due to external forces. This can expose and solve hidden problems in advance and avoid the expansion of hidden problems with the operation of the equipment. Reduce product rework rate, and ensure flange butt joint quality: "horn deformation" is the core problem that leads to the failure of cement pole to meet the flange butt joint requirements, and the ring strip ring can fundamentally reduce the occurrence of such deformation defects through state detection before installation. In the traditional mode, "horn deformation" caused by installation problems can only be found after the cement pole is formed, at which time the product has become a defective product and needs to be reworked or scrapped, not only consuming raw materials and production time, but also increasing the cost of the enterprise. The ring strip ring auxiliary detection can control the quality in advance, solve the problems of chuck, support wheel loosening and coaxiality error in advance, ensure the uniform stress of the end during mold rotation, and avoid "horn deformation" at the contact part of the pole mold two ends and the chuck; the above design not only directly reduces the product defective rate and rework rate caused by installation problems, effectively improves the completion time of a single product, thereby reducing the power consumption of a single product, but also effectively ensures the dimensional accuracy of the cement pole end, so that it can accurately match the subsequent flange butt joint requirements, reduce the secondary processing or product waste caused by butt joint inconsistency, and improve the first-time yield of production; Simplify the detection process and improve the installation and maintenance efficiency: Compared with the traditional method of judging the installation accuracy by using professional detection equipment or complex measurement methods, the ring strip ring combined with the detection method of pre-alignment of the centrifugal block and the hole slot can complete the state judgment through visual observation and simple gap checking without additional complex tools; this detection method is convenient and intuitive to understand, which greatly simplifies the detection process after installation, reduces the high dependence on the professional skills of workers, and shortens the installation and debugging cycle; at the same time, after regular maintenance or replacement of parts, the installation state can also be quickly detected by the same method, reducing the detection time and labor input during maintenance, improving the overall installation and maintenance efficiency, ensuring that the equipment can be put into production faster, and reducing the production gap occupied by detection and debugging.

[0020] 3. The ring strip ring of the present application can bring the following benefits through the design of the ladder face and the wave groove: Enhance the lubricating oil capacity and reduce the maintenance frequency: The design of the ladder face (the cross-sectional face is trapezoidal) and the surface wave groove on the outer periphery of the ring strip ring greatly improves the capacity and storage capacity of the lubricating oil compared with the traditional smooth arc surface or circular arc surface. The smooth arc surface has no recess structure on the surface, and the lubricating oil is easily lost due to centrifugal force or vibration during equipment operation, so it needs to be frequently supplemented to maintain the lubrication effect; the structure of the ladder face can form a natural "oil storage space", and the wave groove further increases the surface oil storage area and oil film adhesion force, which can stably retain more lubricating oil in the contact surface; sufficient lubricating oil reserve can prolong the lubrication period, reduce the frequency of lubricating oil supplement of the contact surface of the chuck and the support wheel, reduce the labor and time cost of daily maintenance of the equipment, and avoid the wear of the contact parts caused by insufficient lubrication; Reduce the risk of dry friction and protect the core components from damage: Dry friction (without lubrication) can cause "metal-to-metal contact" between the chuck and the carrier wheel, which is an important cause of carrier wheel peeling and chuck corner wear when the parts are misaligned. The combination of the ladder surface on the outer periphery of the ring strip ring and the wave groove can effectively store lubricating oil and form a stable oil film at the contact point between the chuck and the carrier wheel, thereby reducing the occurrence of dry friction. Even if the equipment is running for a long time or the lubricating oil is replenished at a longer interval, the ladder surface and the wave groove can still provide lubrication protection for the contact surface, avoiding problems such as local high temperature and metal wear caused by insufficient lubrication, further extending the service life of the carrier wheel and the chuck, and reducing the frequency of replacing core components. Increase auxiliary friction contact surface and improve rotation stability: Based on the existing technology of the contact between the chuck and the carrier wheel ring surface, the design of the ladder surface on the outer periphery of the ring strip ring additionally increases the auxiliary friction contact surface. The traditional smooth arc surface can only achieve contact transmission through a single ring surface, and if the contact surface is slightly worn or not evenly lubricated, it can easily lead to a decrease in transmission stability and cause the mold to rotate and shake. The ladder surface structure can form multiple contact areas, which expands the effective contact area between the chuck and the carrier wheel and improves the friction and transmission reliability between them. During the operation of the equipment, the coordinated action of the multiple contact surfaces can effectively offset the radial offset force when the mold rotates, reducing problems such as rotation jamming and shaking caused by unstable contact, and ensuring that the mold always rotates smoothly, providing a stable centrifugal environment for the uniform molding of cement slurry. Auxiliary automatic centering rotation and enhanced operation adaptability: The design of the ladder surface on the outer periphery of the ring strip ring can further assist the efficient operation of automatic centering rotation based on the protection of lubrication and the reduction of dry friction. The realization of the automatic centering function depends on the flexible adaptation and stable transmission of the contact surface. When the smooth arc surface is not lubricated or slightly worn, it can easily affect the centering accuracy due to unstable friction. The ladder surface design, on the one hand, reduces the fluctuation of the friction resistance of the contact surface through sufficient lubrication, and on the other hand, the multiple auxiliary contact surfaces can provide more uniform support force and guidance for the centering process. When the mold is slightly offset due to uneven distribution of cement slurry or external interference, the ladder surface can quickly guide the chuck and carrier wheel to restore the coaxial state through the coordinated adjustment of multiple contact points, ensuring the response speed and adaptation accuracy of the automatic centering function, and avoiding the problem of part wear or mold rotation abnormalities caused by delayed centering.

[0021] 4、The design of the stability maintenance group can bring the following benefits: The auxiliary ring strip ring self-centering positioning improves the self-centering accuracy and response speed: the cooperation design of the conical centrifugal block and the hole groove in the stability maintenance group can realize dynamic auxiliary positioning in the device working process by means of centrifugal force, greatly optimizing the self-centering effect of the ring strip ring and the ring groove. When the mold rotates to generate centrifugal force, the conical centrifugal block will move outward along the hole groove, and the conical structure can form accurate fitting guidance with the inner wall of the hole groove, which can provide directional restriction force for the ring strip ring through its displacement trend, avoiding the problems of deviation lag or over-adjustment of the ring strip ring in the self-centering process; compared with the self-centering mode which only relies on the structure of the ring strip ring, the above-mentioned "centrifugal block auxiliary restriction guidance" design can make the ring strip ring adapt to the relative position change of the supporting wheel and the chuck more quickly, improve the accuracy and response speed of self-centering, and ensure that the supporting wheel and the chuck are always in a stable cooperation state; Increase the relative fixed point, and strengthen the connection stability of the supporting wheel and the chuck: the cooperation of the conical centrifugal block and the hole groove in the traditional device mainly depends on a single contact area, which is easy to cause relative position deviation due to external force or vibration, and the stability maintenance group additionally increases the relative fixed point between the supporting wheel and the chuck through the cooperation of the conical centrifugal block and the hole groove. Under the action of centrifugal force, the conical centrifugal block is tightly embedded in the hole groove and forms a rigid support, which together with the contact area of the ring strip ring forms a "multi-point fixed system": the ring strip ring is responsible for the basic surface contact cooperation, and the centrifugal block and the hole groove provide additional point locking, which greatly improves the structural stability of the connection between the supporting wheel and the chuck; the above-mentioned multi-fixed point design can effectively resist the radial impact force, vibration interference generated in the mold rotating process, and external force influence when placing the mold, avoiding the loosening or displacement of the supporting wheel and the chuck, and laying a foundation for subsequent stable transmission; Improve the working perfection, and ensure the stability of the production process and the product quality: the design of the stability maintenance group fills the gap of the traditional device in the "dynamic stability control", through the dual functions of "increasing stability point + auxiliary ring strip ring anti-misalignment", the running guarantee system of the device is more perfect, which not only improves the reliability of the device running, but also provides stronger support for the forming quality of the cement electric pole, further improving the working performance of the energy-saving type prefabricated cement electric pole manufacturing equipment.

[0042] It should be noted that: Under the traditional “line contact”, uneven distribution of the cement slurry can easily cause misalignment eccentric wear, which can double the local contact stress, cause the “peeling” of the carrier wheel surface and the “chamfer wear” of the chuck edge; the anti-misalignment eccentric wear group 4 can effectively disperse the misalignment contact pressure through the self-adaptive cooperation of the ring strip ring 404 and the ring groove 407, avoid stress concentration, and effectively reduce the peeling of the carrier wheel and the wear of the chuck.

[0043] Compared to traditional methods that require specialized testing equipment or complex measurement techniques to determine installation accuracy, the detection method that combines the ring 404 with the pre-aligned centrifugal block 503 and the slot 504 eliminates the need for additional complex tools. The status can be determined simply by visual observation and a basic check of the fit gap.

[0044] The trapezoidal structure of the ring 404 can form a natural "oil storage space", while the wave groove 405 further increases the surface oil storage area and oil film adhesion, which can stably retain more lubricating oil on the contact surface. In addition, based on the contact between the chuck and the roller ring in the existing technology, the design of the trapezoidal surface of the outer periphery of the ring 404 adds an auxiliary friction contact surface.

[0045] A further embodiment: A method for manufacturing energy-saving precast concrete utility poles includes the following steps: Step 1: Skeleton Construction Stage Steel pretreatment: PC steel is used, which is straightened using a straightening machine and then cut to a fixed size; at the same time, reinforcing bars are prepared for subsequent binding and reinforcement. Outer steel frame binding: Cut PC steel bars are grouped into sets of 20 and conveyed to the binding machine via a crawler; the steel bars are tied and spot-welded to the ring steel frame to enhance plasticity, and then pulled out from the other end by a traction machine to form a standard outer steel frame. Workers then manually reinforce and bind both ends. Inner steel frame fabrication: Cut steel bars and move them to the operating position. Insert the steel bars using the ring retainer to ensure that the spacing between the steel bars is consistent. Insert the protruding end of the steel bar into the traction machine. Move the traction table to the bottom of the fixed plate to support the steel bar, forming the inner steel frame. Double-layer steel frame assembly: Workers pull the inner steel frame to the outer steel frame platform. Two workers work together to move the outer steel frame onto the track. The electric traction machine is started so that the inner steel frame passes through the outer steel frame. A fixed ring is used to form a closed opening at one end, and a fixed plate is connected to the other end. Steel bars are inserted to make the whole structure hollow. Finally, it is thoroughly tied and fixed with thin steel wire to complete the prefabricated steel frame. Step Two: Mold Preparation and Assembly Stage (304 Stainless Steel) Mold 304 pretreatment: The concrete pouring mold 304 is made of steel and the inside is sprayed with high-temperature ceramic particles. First, the outer shell of the mold 304 is heated and sprayed with oil. Steel frame and mold 304 assembly: The prefabricated steel frame is placed into the casting shell, i.e. mold 304, using a mechanical hook. After confirming that everything is correct, the fastening operation is performed to ensure complete closure. Anti-dislocation and abrasion assembly of mold 304: Fix chuck B 406 on mold 304, and open ring groove 407 and hole groove 504 on the outer periphery of chuck B 406; align the carrier wheel B 401 on the drive shaft rod 302 with the chuck B 406, so that the ring strip ring 404 on the outer ring surface of the carrier wheel B 401 is clamped into the ring groove 407 of the chuck B 406, and at the same time the carrier wheel B 401 is fixed between the circular pieces of the drive shaft rod 302 through the attached piece 402 and the fastener 403, completing the anti-dislocation and abrasion structure assembly; add lubricating oil in advance in the wave groove 405 of the ring strip ring 404 to reduce the dry friction between the carrier wheel B 401 and the chuck B 406.

[0046] Step three: concrete preparation and pouring stage Concrete preparation: the truck pours the concrete stones into the ground delivery port, the stones are filtered through the screen to discharge large stones, and the stones are transported to the top of the concrete processing tank by the conveyor belt; the cement ash and water in the processing tank are automatically released and adjusted according to the set proportion, and are mixed and stirred until completely uniform; Concrete pouring: the automatic transport table sends the concrete grouting pipe into the deepest part of the pouring shell mold 304, the grouting pipe swings to pour concrete, and at the same time it slowly exits at a fixed uniform speed to ensure that the pouring is sufficient and the internal grouting amount is guaranteed; before pouring, hidden dangers such as loosening of the fastener 403 and displacement of the parts are checked through the clamping state of the ring strip ring 404 and the ring groove 407, the pre-alignment gap between the centrifugal block 503 on the carrier wheel B 401 and the hole groove 504 of the chuck B 406, to ensure the installation accuracy of the mold 304; Step four: shaping and curing stage Safety protection start: start safety protection group 2, the hinge plate 203 is rotated about the opening and closing shaft 202, the safety protection mode is started, and the material splashing in the shaping process is avoided; Centrifugal rotation shaping: start the drive shaft rod 302 to drive the carrier wheel A 303 and the carrier wheel B 401 to rotate synchronously, the carrier wheel A 303 drives the mold 304 to rotate through the static friction with the chuck A 306, and the carrier wheel B 401 drives the mold 304 to rotate through the cooperation of the ring strip ring 404 and the ring groove 407; the "automatic centering contact" of the ring strip ring 404 and the ring groove 407 replaces the traditional "line contact", disperses the dislocation contact pressure, avoids the carrier wheel peeling and the chuck abrasion, and ensures the stable rotation of the mold 304; During the rotation of the mold 304, the centrifugal block 503 in the cylindrical groove 501 of the carrier wheel B 401 moves outward under the action of centrifugal force and is embedded in the hole groove 504 of the chuck B 406, forming a "multi-point fixing system" with the ring strip ring 404, offsetting the radial offset force of the mold 304, and preventing the "horn mouth deformation" caused by the force imbalance of the end of the mold 304; at the same time, the lubricating oil in the wave groove 405 maintains a stable oil film between the ring strip ring 404 and the chuck B 406, reducing the dry friction damage between the carrier wheel and the chuck; After high-speed finishing, the excess water in the concrete is discharged to make the concrete adhere to the inner wall of the mold 304 to form a hollow shape and complete the preliminary condensation and solidification; after the rotation stops, the workers remove the bottom plate 307 of the mold 304 with tools to allow the residual water inside to flow out naturally; Accelerated curing and drying: The hoisting machine places the pouring mold 304 in the drying chamber, and then the pouring mold 304 is dried to ensure that the concrete is completely cured and formed.

[0047] Step five: demolding and post-processing stage Demolding operation: After drying, the machine removes all screws of the shell mold 304, and the operator remotely controls the crane to remove the mold 304 shell; the high-pressure suction cup is used to suck the finished product pole, which is lifted and placed on the transport belt; Finished product cleaning and marking: The worker carefully knocks the circular ring of the fixed steel rod at the bottom of the pole with a hammer to clean the attached cement blocks; a special stamp is used to print key information on the pole; Factory inspection: Before leaving the factory, the worker checks the surface of the pole with a flashlight to check for cracks, gaps, and other defects, and confirms that the end part has no “horn deformation”, ensuring that the finished product meets the flange butt joint requirements, and finally completes the qualified product leaving the factory.

[0048] The working principle of all the above contents in the embodiments is as follows: Initial state: The two folding plates 203 are in contact with each other and are in a safe protection mode, as shown in the accompanying Figure 1 ; The mold 304 is not placed on the supporting wheels A 303 and B 401 by the hoisting device; the ring strip ring 404 is not clamped in the ring groove 407 of the chuck B 406 fixedly connected to the mold 304; and the spring 502 is in a normal relaxed state.

[0049] In use, the safety protection group 2 is started, and the opening and closing shaft 202 moves with the folding plate 203 under the drive of the drive motor, and the moving folding plate 203 rotates around the opening and closing shaft 202 as the rotation axis. The two folding plates 203 facing each other in rotation will open the safety protection group 2 in the original closed protection state, which can be referred to in the accompanying Figure 2 , at this time the hoisting of the mold 304 can be performed; Further, during hoisting, the external hoisting machine hoists the mold 304 with the chuck A 306 and the chuck B 406 and places it on the manufacturing group 3. Specifically, the mold 304 is supported by adjacent supporting wheels, which can be referred to in the accompanying Figure 3Further, during the placement of the mold 304, the chuck A 306 on the mold 304 needs to be aligned with the supporting wheel A 303 on the driving shaft rod 302, and the chuck B 406 on the mold 304 needs to be aligned with the supporting wheel B 401 on the driving shaft rod 302. Specifically, the ring strip ring 404 on the supporting wheel B 401 needs to be clamped in the ring groove 407 opened on the chuck B 406; Further, before the cement slurry is added, the pre-alignment operation of the centrifugal block 503 and the hole groove 504 in the stability maintenance group 5 needs to be performed; specifically, the position of the mold 304 is adjusted by the hoisting machine, and manual assistance is needed; at this time, the placement process of the mold 304 is completed, and the addition of the cement slurry can be performed; Further, during the addition of the cement slurry, the concrete pouring pipe is inserted into the inner cavity of the mold 304 from the hole opened on the bottom plate 307, so as to add the concrete material; after the addition is completed, the pouring pipe is withdrawn; then the opening and closing shaft 202 is controlled to rotate with the folding plate 203, and the safety protection state is adjusted; Further, during the work, the driving shaft rod 302 rotates with the supporting wheel A 303 and the supporting wheel B 401, and the mold 304 supported thereby rotates; with the rotation of the mold 304, the concrete material originally in the inner cavity moves to the inner wall of the mold 304 under the action of the centrifugal force and finally adheres to the inner wall of the mold 304; during the above process, the ring strip ring 404 on the supporting wheel B 401 cooperates with the ring groove 407 opened on the chuck B 406, so as to limit the dislocation of the mold 304 fixedly connected with the chuck B 406; during the process, the lubricating oil in the wave groove 405 can avoid the damage of the components caused by the dry friction; during the process, on the basis of the “line contact” state of the existing supporting wheel A 303 and the chuck A 306, the anti-dislocation and eccentric wear group 4 changes the “line contact” of the supporting wheel B 401 and the chuck B 406 into “automatic centering contact” through the cooperation of the ring strip ring 404 and the ring groove 407, which fundamentally improves the contact state of the supporting wheel and the chuck. Under the traditional “line contact”, uneven distribution of cement slurry can easily cause dislocation and eccentric wear, which can double the local contact stress, and further cause the “peeling” of the surface of the supporting wheel and the “chamfer wear” of the edge of the chuck. Such damage can greatly shorten the replacement cycle of the supporting wheel and the chuck, increase the labor and material costs of equipment maintenance; the anti-dislocation and eccentric wear group 4 can effectively disperse the dislocation contact pressure through the self-adaptive cooperation of the ring strip ring 404 and the ring groove 407, avoid stress concentration, effectively reduce the faults such as peeling of the supporting wheel and wear of the chuck, significantly prolong the service life of the supporting wheel and the chuck, reduce the replacement frequency of the core components, avoid the power consumption caused by equipment downtime maintenance and restart, save energy, reduce equipment maintenance cost and downtime repair time, improve the rotation stability of the mold 304, and ensure the continuity of the production process; Further, the existence of the ring strip circle 404 and the ring groove 407 can provide an intuitive and convenient carrier for detecting the installation state of the chuck and the carrier wheel. Especially in the operation link of pre-alignment of the centrifugal block 503 and the hole groove 504 before work, the workers can effectively observe whether the device components are loose by means of the cooperation state of the ring strip circle 404 and the ring groove 407 and the centrifugal block 503 and the hole groove 504. Unlike the phenomenon of uneven bolt tightness during installation of the traditional equipment in the prior art, the loose of the chuck or the carrier wheel caused by external force when placing the mold 304, etc., which often needs to be indirectly discovered through abnormal rotation of the mold 304 or product defects after the equipment is running, at this time, the equipment loss or production waste has been caused; through the auxiliary detection of the ring strip circle 404, the hidden troubles can be actively investigated before installation or work, for example, whether the ring strip circle 404 on the carrier wheel B401 and the ring groove 407 on the chuck B406 are uniformly attached, whether there is a shift gap when the centrifugal block 503 and the hole groove 504 are pre-aligned, so as to quickly judge whether the fastener 403 is loose, whether the components are displaced due to external force, expose and solve the hidden problems in advance, and avoid the expansion of hidden troubles with the equipment running; Further, compared with the traditional smooth arc surface or circular arc surface, the design of the ladder surface of the ring strip circle 404 and the opening of the wave groove 405 greatly improve the accommodation and storage capacity of the lubricating oil; sufficient lubricating oil reserve can prolong the lubrication period, reduce the lubricating oil supplement frequency of the contact surface of the chuck and the carrier wheel by the workers, reduce the labor and time cost of daily maintenance of the equipment, and avoid the wear and tear of the contact components caused by untimely lubrication; at the same time, the traditional smooth arc surface can only realize contact transmission through a single ring surface, if the contact surface is slightly worn or unevenly lubricated, it is easy to cause the transmission stability to decrease, and the mold 304 to shake; the structure of the ladder surface of the ring strip circle 404 can form multiple contact areas, which expands the effective contact area of the chuck and the carrier wheel and improves the friction and transmission reliability between them; in the working process of the equipment, the cooperative action of the multiple contact surfaces can effectively offset the radial offset force when the mold 304 rotates, reduce the problems of rotation jamming and shaking caused by unstable contact, and ensure that the mold 304 always rotates smoothly, providing a stable centrifugal environment for uniform molding of the cement slurry; Further, in the process of rotating the mold 304 by the chuck through the carrier wheel A303 and the carrier wheel B401, the centrifugal block 503 in the cylindrical groove 501 opened on the carrier wheel B401 will move to the outer ring surface of the carrier wheel B401 under the action of the centrifugal force, that is, the moving centrifugal block 503 will enter the hole groove 504 opened on the chuck B406, at this time, the spring 502 is stretched; In the above process, the cooperation between the conical centrifugal block 503 and the hole groove 504 in the stability maintenance group 5 can realize dynamic auxiliary positioning in the working process of the device by means of centrifugal force, greatly optimizing the self-centering effect of the ring strip ring 404 and the ring groove 407. When the mold 304 rotates to generate centrifugal force, the conical centrifugal block 503 will move outward along the hole groove 504, and its conical structure can form precise fitting guidance with the inner wall of the hole groove 504, providing directional restriction force for the ring strip ring 404 through its displacement trend, avoiding the problems of deviation lag or over-adjustment of the ring strip ring 404 in the self-centering process; compared with the self-centering mode relying only on the structure of the ring strip ring 404 itself, the above-mentioned "centrifugal block 503 auxiliary restriction guidance" design can make the ring strip ring 404 adapt to the relative position change of the supporting wheel B401 and the chuck B406 faster, improve the accuracy and response speed of self-centering, and ensure that the supporting wheel and the chuck are always in a stable cooperation state. Further, the stability maintenance group 5 additionally increases the relative fixing points between the supporting wheel and the chuck through the cooperation of the conical centrifugal block 503 and the hole groove 504; under the action of centrifugal force, the conical centrifugal block 503 is tightly embedded in the hole groove 504 and forms a rigid support, and the contact area of the ring strip ring 404 and the hole groove 504 together constitute a "multi-point fixing system", that is, the ring strip ring 404 is responsible for the basic surface contact cooperation, and the centrifugal block 503 and the hole groove 504 provide additional point locking, and the cooperation of the two greatly improves the structural stability of the connection between the supporting wheel and the chuck.
