Description

Technical Field

[0001] This invention relates to the field of pole processing technology, and in particular to an energy-saving pole centrifugal device. Background Technology

[0002] In power transmission projects, concrete poles serve as core components supporting transmission lines, and their molding quality directly determines the safety and stability of power transmission. Currently, the molding of concrete poles mainly relies on centrifugal molding technology. Centrifugal equipment drives the mold to rotate at high speed, utilizing centrifugal force to compact the concrete and form a hollow pole structure that meets requirements. However, in the centrifugal molding process of existing pole molding equipment, the sand, cement paste, and water in the concrete are prone to stratification under centrifugal force. The outer layer of aggregate is dense, while the inner layer of laitance is excessively thick and structurally loose. This results in significant differences in strength and density between the inner and outer layers of the pole, easily leading to defects such as honeycomb, holes, and hollow areas on the inner wall. This reduces the pole's bending and crack resistance, shortening its service life. Summary of the Invention

[0007] As a preferred embodiment of the present invention, the hollow column is provided with a sealing strip for sealing the gaps in the hollow column on the inner wall near the spiral agitator plate, and the surface of the sealing strip near the spiral agitator plate is provided with a lubrication structure.

[0008] As a preferred embodiment of the present invention, the spiral guide rib is configured with a rounded chamfered trapezoidal cross section for reducing shear damage to the aggregate. The spiral guide rib has multiple exhaust holes for exhausting on its surface inside the centrifuge tube, and a water-resistant and breathable membrane is provided in the exhaust holes.

[0009] As a preferred embodiment of the present invention, a water replenishment mechanism is provided at the top of the support frame. The water replenishment mechanism includes a pump body fixedly installed at the top of the support frame. A plurality of second rotating plates are fixedly installed on the outer surface of the centrifuge cylinder. A first rotating plate is rotatably installed on the outer surface of the second rotating plates. A water inlet component is connected to the input end of the pump body through a rotary joint.

A water outlet component is connected to the free end of the connecting pipe. The water outlet component is connected to the inner top end of the centrifuge cylinder through the first and second rotating plates at the top of the centrifuge cylinder.

[0010] As a preferred embodiment of the present invention, the water inlet component is provided with a filter component, and the interior of the filter component is filled with a bottom chamber for settling concrete impurities.

[0011] As a preferred embodiment of the present invention, the water inlet component is provided with an agitation assembly, the agitation assembly including a rotating rod rotatably installed inside the water inlet component pipe, a scraper fixedly installed at the free end of the rotating rod, a disc provided on the water inlet component, and the scraper scraping inside the disc, an agitation wire fixedly installed on the surface of the rotating rod near the filter plate, a fourth motor fixedly installed at the top of the filter component, and a belt drivingly connecting the output shaft of the fourth motor and the rotating rod.

[0012] As a preferred embodiment of the present invention, the support frame is provided with two symmetrically installed viscoelastic dampers near the top of the centrifuge cylinder, and pressure plates for stabilizing the centrifuge pole are fixedly installed on the surfaces of the viscoelastic dampers that are close to each other.

[0013] As a preferred embodiment of the present invention, the two ends of the support frame are provided with load-bearing boxes for stabilizing the centrifuge cylinder, and the interior of the load-bearing boxes is filled with load-bearing blocks.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention applies composite disturbance to the concrete from both the inside and outside of the centrifuge drum through a sliding spiral guide rib and a contracting spiral agitator plate. During the low-speed material distribution stage, this disturbance mechanism effectively breaks down the initial setting interface between coarse and fine aggregates and establishes an exhaust channel. This not only prevents the concrete aggregates from being sheared and damaged, but also fully agitates the concrete, promptly removes internal air bubbles, breaks down the stratification interface between sand, cement paste, and water during centrifugation, and prevents axial movement of the concrete. This ensures uniform strength and density inside and outside the pole, reduces defects such as laitance, honeycomb, and voids on the inner wall, and significantly improves the forming quality and structural stability of the pole.

[0015] 2. The present invention uses a second spring to push the insertion rod to fit into the centrifuge tube. With the support frame's load-bearing boxes at both ends and symmetrically arranged viscoelastic dampers and pressure plates, it effectively limits the offset, swaying and vibration of the centrifuge tube when it rotates at high speed, reducing equipment wear and noise. At the same time, the first spring connects the first motor and the spiral guide ribs to achieve adaptive adjustment of the guide structure, further improving the equipment's operational stability and energy efficiency.

[0016] 3. This invention forms a closed loop through the water inlet component, filter component, pump body and water outlet component, which can recover excess water discharged during the centrifugation process. The bottom chamber of the filter component settles concrete impurities, and the scraper and stirring wire of the stirring component prevent the filter plate from clogging and impurities from accumulating. The purified water is recycled for replenishing concrete in the centrifuge cylinder, which avoids water waste and environmental pollution, and reduces water replenishment costs in the production process.

[0017] 4. The invention can effectively seal gaps through the sealing strip on the inner wall of the hollow column, preventing concrete slurry from entering the hollow column and damaging components such as the rotating shaft and rotating connectors. The lubrication structure on the surface of the sealing strip reduces the sliding friction between the spiral agitator and the hollow column, reduces component wear, reduces the equipment failure rate, and extends the service life of the overall equipment.

[0018] 5. This invention, through the sliding design of the spiral guide ribs and the rotating structure of the spiral stirring plate, can adapt to the centrifugal forming requirements of poles with different speeds and specifications, without the need for frequent equipment adjustments. It not only solves the problems of uneven forming quality and cumbersome operation of traditional equipment, but also effectively improves the production efficiency of poles.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Please see Figure 1-10This invention provides an energy-saving pole centrifuge device, including a support frame 1, a centrifugal mechanism 3 at the top of the support frame 1, a centrifugal cylinder 35 rotatably mounted at the top of the support frame 1, a third motor 31 fixedly mounted at the top of the support frame 1, a gear 32 fixedly mounted on the output shaft of the third motor 31, a limit assembly 34 on the outer side of the centrifugal cylinder 35, a gear ring 33 fixedly mounted on the outer side of the limit assembly 34, and the gear 32 meshing with the gear ring 33, a flow guiding mechanism 2 near the top of the centrifugal cylinder 35 on the support frame 1, the flow guiding mechanism 2 including a spiral flow guiding rib 24 slidably mounted on the inner wall of the centrifugal cylinder 35, and the spiral flow guiding rib 24 embedded in the inner wall of the centrifugal cylinder 35, a first motor 21 fixedly mounted on the surface of the support frame 1, a top plate 23 fixedly mounted on the bottom end of the spiral flow guiding rib 24, and a first spring 22 fixedly mounted between the output shaft of the first motor 21 and the top plate 23.

[0023] The process begins with the third motor 31 being started. After the power is connected, the output shaft of the third motor 31 rotates at a constant speed. Since the gear 32 and the gear ring 33 mesh with each other, the rotation of the gear 32 synchronously drives the gear ring 33 to rotate. The gear ring 33 is fixedly connected to the limiting component 34, thereby driving the limiting component 34 and the centrifugal cylinder 35, which cooperates with the limiting component 34, to rotate smoothly together on the preset track at the top of the support frame 1. During the rotation of the centrifugal cylinder 35, centrifugal force is generated, and the concrete inside gradually moves towards the cylinder wall under the action of centrifugal force, beginning initial compaction and formally entering the centrifugal forming process of the electric pole. Simultaneously, when the centrifugal cylinder 35 rotates, it drives the spiral guide ribs 24 embedded in the mounting groove on the inner wall to rotate synchronously. At this time, the first motor 21 is started, and the output shaft of the first motor 21 performs reciprocating extension and retraction motion. Through the first springs 22 fixed at both ends, it drives the top plate 23 to move up and down. The top plate 23 is fixedly connected to the bottom end of the spiral guide ribs 24, thereby pulling the spiral guide ribs 24 to slide back and forth in the mounting groove on the inner wall of the centrifugal cylinder 35. At this time, under the elastic compensation of the first spring 22, the spiral guide rib 24 automatically adjusts the clamping force as the concrete density increases, and its reciprocating sliding motion gradually slows down. Utilizing its spiral angle, it plays a compacting role on the outer wall of the formed pole, similar to "polishing," ensuring the longitudinal uniformity of aggregate distribution and ultimately achieving consistency in the strength of the inner and outer parts of the pole. This avoids damage to the concrete aggregate or wear of the spiral guide rib 24 caused by rigid contact. Through the synergistic effect of rotation and reciprocating sliding, the spiral guide rib 24 axially pushes and combs the concrete in the centrifuge cylinder 35, effectively preventing the concrete from axially shifting along the length of the pole and ensuring uniform distribution of concrete within the centrifuge cylinder 35. When the centrifuge cylinder 35 accelerates to the second preset high speed, the second motor 28 stops working, and the spiral stirring plate 26 retracts to the surface of the hollow column 25 under the action of the rotating connector 29 to avoid interfering with the final compaction of the concrete.

[0024] In some embodiments, the limiting component 34 includes an annular frame 342 fixedly installed at the bottom end of the toothed ring 33. A fixing rod 344 is fixedly installed on the surface of the annular frame 342 near the centrifuge cylinder 35. An insert rod 343 is slidably installed inside the fixing rod 344 and is inserted into the limiting hole on the outer side wall of the centrifuge cylinder 35. A second spring 341 is fixedly installed between the insert rod 343 and the inner wall of the fixing rod 344.

[0025] During the high-speed rotation of the centrifuge cylinder 35, the second spring 341 remains compressed, continuously applying an elastic thrust towards the centrifuge cylinder 35 to the insertion rod 343. This pushes the end of the insertion rod 343 tightly into the limiting hole on the outside of the centrifuge cylinder 35, forming a circumferential limit on the centrifuge cylinder 35 and restricting its radial displacement. When the centrifuge cylinder 35 experiences slight radial displacement or wobbling due to load changes or speed fluctuations during rotation, the insertion rod 343 will adaptably slide along the sliding channel of the fixed rod 344 under the elastic action of the second spring 341, always maintaining a tight fit with the limiting hole of the centrifuge cylinder 35, continuously playing a limiting role, and preventing excessive displacement of the centrifuge cylinder 35 from affecting the pole forming quality. This achieves stable limiting of the centrifuge cylinder 35 throughout the entire process.

[0026] In some embodiments, a hollow column 25 is fixedly installed inside the centrifuge cylinder 35, and a spiral agitator 26 slides through the outer surface of the hollow column 25. The spiral agitator 26 is used to agitate the concrete inside the centrifuge cylinder 35. A rotating shaft 211 is rotatably installed inside the hollow column 25. A rotating connector 29 is provided between the rotating shaft 211 and the spiral agitator 26. A support rod 27 is fixedly installed at the top of the support frame 1. A second motor 28 is fixedly installed at one end of the support rod 27. The output shaft of the second motor 28 is fixedly connected to the rotating shaft 211.

[0027] When the third motor 31 is started to drive the centrifuge drum 35 to rotate at a first preset low speed, the concrete adheres to the drum wall under the initial centrifugal force. At this time, the second motor 28 is started, and the output shaft of the second motor 28 drives the rotating shaft 211 to rotate at a constant speed inside the hollow column 25. When the rotating shaft 211 rotates, it transmits power through the rotating connector 29, causing the spiral stirring plate 26 to slide and rotate on the outer surface of the hollow column 25. At the same time, the first motor 21 drives the spiral guide rib 24 to slide axially back and forth on the inner wall of the centrifuge drum. During the process of the centrifuge drum 35 rotating and generating centrifugal force, causing the concrete to gradually compact to the outer layer, the spiral stirring... Plate 26 shears and mixes from the inner layer of concrete, breaking the separation interface between the slurry and aggregate. At the same time, the spiral guide bar 24 uses its rounded and chamfered trapezoidal cross section to push axially from the outer layer. This composite disturbance logic of "inner and outer double radial + axial" can force the air bubbles inside the concrete to gather towards the center and be discharged through the vent holes on the surface of the spiral guide bar 24, effectively preventing early segregation caused by the difference in aggregate particle size. After the centrifuge cylinder 35 has completely stopped rotating, clean the concrete adhering to the surface of the spiral agitator plate 26, check the operating status of the rotating connector 29 and the rotating shaft 211, and complete the reset.

[0028] In some embodiments, a sealing strip 210 for sealing the gaps in the hollow column 25 is provided on the inner wall near the spiral agitator 26, and a lubrication structure is provided on the surface of the sealing strip 210 near the spiral agitator 26.

[0029] When the second motor 28 starts, the rotating shaft 211 drives the spiral agitator 26 to slide and rotate on the outer surface of the hollow column 25. At this time, the sealing strip 210 begins to function, closely conforming to the sliding trajectory of the spiral agitator 26 and sealing all gaps between the hollow column 25 and the spiral agitator 26. This prevents the high-speed rotating concrete slurry from entering the hollow column 25 through the gaps during centrifugation and avoids the slurry adhering to the surfaces of the rotating shaft 211 and the rotating connector 29. Simultaneously, the lubrication structure on the surface of the sealing strip 210 reduces the sliding friction between the spiral agitator 26 and the sealing strip 210 during the sliding process, lowering frictional resistance and ensuring that the spiral agitator 26 can slide smoothly and rotate stably without jamming or getting stuck. This does not affect the normal working efficiency of the agitation mechanism and also avoids component wear caused by excessive friction.

[0030] In some embodiments, the spiral guide rib 24 is configured with a rounded chamfered trapezoidal cross section to reduce shear damage to the aggregate. The spiral guide rib 24 has a plurality of exhaust holes for exhausting on its surface inside the centrifuge cylinder 35, and a water-resistant and breathable membrane is provided in the exhaust holes.

[0031] After the equipment is started, the centrifuge drum 35 drives the spiral guide rib 24 to rotate synchronously. At the same time, the first motor 21 drives the spiral guide rib 24 to slide back and forth on the inner wall of the centrifuge drum 35. The spiral guide rib 24 begins to guide and comb the concrete axially. Since the spiral guide rib 24 adopts a rounded and chamfered trapezoidal cross section, the contact stress between it and the concrete aggregate is greatly reduced. During the guiding process, it can effectively avoid shear damage to the concrete aggregate, prevent the aggregate from breaking and affecting the strength of the pole, and reduce the resistance of the guide rib to the concrete, making the guiding process smoother and improving the guiding efficiency. Under centrifugal force, a large number of air bubbles are generated inside the concrete. These air bubbles move inward as the concrete compacts. When the air bubbles come into contact with the surface of the spiral guide bar 24, they are discharged in time through the vent holes, reducing the porosity inside the concrete and preventing defects such as honeycomb, holes, and hollow areas from appearing on the inner wall of the pole. The water-resistant and breathable membrane inside the vent holes allows air bubbles to pass through smoothly, while effectively preventing concrete slurry from leaking through the vent holes, avoiding slurry loss that could lead to an imbalance in the concrete mix ratio, and ensuring the uniformity and density of the concrete.

[0032] In some embodiments, a water replenishment mechanism 4 is provided at the top of the support frame 1. The water replenishment mechanism 4 includes a pump body 41 fixedly installed at the top of the support frame 1. A plurality of second rotating plates 49 are fixedly installed on the outer surface of the centrifuge cylinder 35. A first rotating plate 48 is rotatably installed on the outer surface of the second rotating plates 49. A water inlet component 44 is connected to the input end of the pump body 41 through a rotary joint. The water inlet component 44 is connected to the inner bottom end of the centrifuge cylinder 35 through the first rotating plate 48 and the second rotating plate 49 at the bottom end of the centrifuge cylinder 35. A filter plate 47 is provided at one end of the water inlet component 44 near the centrifuge cylinder 35. A connecting pipe 45 is connected to the output end of the pump body 41. A water outlet component 46 is connected to the free end of the connecting pipe 45. The water outlet component 46 is connected to the inner top end of the centrifuge cylinder 35 through the first rotating plate 48 and the second rotating plate 49 at the top of the centrifuge cylinder 35.

[0033] When the centrifugal mechanism 3 is started, the centrifugal cylinder 35 rotates at high speed. Under the action of centrifugal force, the concrete begins to compact, and excess water is released. This water collects at the bottom of the centrifugal cylinder 35. At this time, the pump body 41 is started and begins to work. The pump body 41 extracts the excess water at the bottom of the centrifugal cylinder 35 through the water inlet component 44. The water first passes through the filter plate 47, which performs preliminary filtration of large concrete particles in the water to prevent impurities from entering the pump body 41 and the pipeline. The filtered water is then drawn into the pump body 41 and, through the pressurization of the pump body 41, is transported to the water outlet component 46 through the connecting pipe 45. The water outlet component 46 sends the water into the top of the centrifugal cylinder 35 through the first rotating plate 48 and the second rotating plate 49 at the top of the centrifugal cylinder 35, realizing the recycling of water and timely replenishing the water lost during the concrete centrifugation process, ensuring the stability of the concrete mix ratio. Throughout the water replenishment process, the centrifuge cylinder 35 remains in a high-speed rotation state. The first rotating plate 48 and the second rotating plate 49 rotate in coordination. The first rotating plate 48 is fixed at the end of the water inlet component 44 and the water outlet component 46, while the second rotating plate 49 is fixed on the outside of the centrifuge cylinder 35. The two rotate relative to each other, ensuring that the water inlet and outlet channels remain unobstructed and do not interfere with the rotation of the centrifuge cylinder 35 or the concrete forming process. Furthermore, through circulating water replenishment, the moisture lost by the pole under specific conditions such as high temperature or long-term centrifugation can be effectively replenished, preventing the pole surface from developing shrinkage cracks due to excessive water loss and ensuring the overall structural strength of the pole.

[0034] The water inlet component 44 is fixedly provided with a stationary ring at its end, and the centrifuge cylinder 35 is fixedly provided with a rotating ring coaxial with the second rotating plate 49 at its end. The stationary ring and the rotating ring fit together to form an end face mechanical seal, so that when the centrifuge cylinder 35 rotates at high speed, the stationary water inlet component 44 can maintain a sealed connection with the bottom of the centrifuge cylinder.

[0035] In some embodiments, the water inlet component 44 is provided with a filter component 42, the interior of which is filled with a bottom chamber for settling concrete impurities.

[0036] In this system, pump body 41 extracts excess water from the bottom of centrifuge cylinder 35. After initial filtration by filter plate 47, the water enters inlet component 44 and then flows into filter component 42. The water flows slowly within filter component 42, and fine concrete impurities in the water gradually settle to the bottom chamber of filter component 42 under gravity, achieving secondary filtration of the circulating water, removing fine impurities and ensuring the purity of the circulating water. The filtered pure water continues to flow within inlet component 44, is drawn in and pressurized by pump body 41, and transported to outlet component 46, ultimately flowing back into centrifuge cylinder 35 to replenish the water lost from the concrete.

[0037] In some embodiments, an agitation assembly 43 is provided on the water inlet component 44. The agitation assembly 43 includes a rotating rod 433 rotatably installed inside the pipe of the water inlet component 44. A scraper 434 is fixedly installed at the free end of the rotating rod 433. A disc 435 is provided on the water inlet component 44, and the scraper 434 scrapes inside the disc 435. An agitation wire 436 is fixedly installed on the surface of the rotating rod 433 near the filter plate 47. A fourth motor 431 is fixedly installed at the top of the filter component 42. A belt 432 is driven between the output shaft of the fourth motor 431 and the rotating rod 433.

[0038] The fourth motor 431 is activated, and its output shaft rotates, driving the rotating rod 433 to rotate at a constant speed inside the water inlet component 44 via the belt 432. As the rotating rod 433 rotates, the agitating wires 436 on its surface rotate synchronously, agitating the water inside the water inlet component 44. This prevents impurities in the water from accumulating on the surface of the filter plate 47, thus preventing clogging and ensuring smooth water intake and efficient circulation of the water replenishment mechanism 4. Simultaneously, the scraper 434 at the free end of the rotating rod 433 rotates with it, scraping back and forth inside the disc 435 to clean impurities adhering to the inner wall of the disc 435. This prevents impurities from accumulating inside the disc 435 and clogging the water flow channel, ensuring smooth filtration and water replenishment processes.

[0039] In some embodiments, the support frame 1 is provided with two symmetrically installed viscoelastic dampers 6 near the top of the centrifuge cylinder 35, and pressure plates 5 for stabilizing the electric pole centrifuge are fixedly installed on the surfaces of the viscoelastic dampers 6 that are close to each other.

[0040] After the equipment is started, the centrifugal mechanism 3 begins operation, and the centrifuge cylinder 35 rotates at high speed. During this rotation, vibrations are generated and transmitted to the support frame 1 and the surrounding environment. At this time, the symmetrically installed viscoelastic dampers 6 begin to function, utilizing their viscoelastic properties to absorb the vibration energy generated by the rotation of the centrifuge cylinder 35, attenuating the vibration amplitude, reducing the overall vibration intensity and noise of the equipment, and minimizing interference with the surrounding environment. Simultaneously, under the action of vibration, the viscoelastic dampers 6 apply stable lateral pressure to the centrifuge cylinder 35 through the pressure plate 5. The pressure plate 5 is tightly fitted to the outside of the centrifuge cylinder 35, restricting the lateral swaying of the centrifuge cylinder 35 and preventing lateral displacement during high-speed rotation. This ensures that the centrifuge cylinder 35 remains in a stable rotational state, guaranteeing that the centrifugal force is evenly applied to the concrete and preventing secondary segregation of the concrete caused by vibration.

[0041] In some embodiments, the support frame 1 is provided with load-bearing boxes at both ends for stabilizing the centrifuge cylinder 35, and the interior of the load-bearing boxes is filled with load-bearing blocks.

[0042] The load-bearing blocks inside the load-bearing boxes at both ends of the support frame 1 act as counterweights. By increasing the overall weight of the support frame 1 and optimizing the center of gravity distribution, they offset some of the centrifugal force and the impact force generated by vibration, preventing the support frame 1 from tilting or swaying and ensuring that the support frame 1 remains stable. This provides a stable bearing foundation for components such as the centrifuge cylinder 35, the flow guiding mechanism 2, and the water replenishment mechanism 4. Throughout the centrifugal forming process, the load-bearing boxes and load-bearing blocks play a stabilizing role, working together with the limiting component 34 and the viscoelastic damper 6 to ensure the stable rotation of the centrifuge cylinder 35 and guarantee the quality of the pole forming.

[0043] Working principle: Concrete raw materials are injected into the centrifuge cylinder 35 according to the preset ratio to ensure that the filling amount of raw materials meets the requirements of the pole forming specifications. First, the third motor 31 is started. After the power is turned on, the output shaft of the third motor 31 rotates at a constant speed. Since the gear 32 and the gear ring 33 mesh with each other, the gear 32 drives the gear ring 33 to rotate synchronously when it rotates. The gear ring 33 is fixedly connected to the limiting component 34, which in turn drives the limiting component 34 and the centrifuge cylinder 35 that cooperates with the limiting component 34 to rotate smoothly together on the preset track at the top of the support frame 1. During the rotation of the centrifuge cylinder 35, centrifugal force is generated. Under the action of centrifugal force, the concrete inside gradually moves towards the cylinder wall and begins to be initially compacted, thus formally entering the centrifugal forming process of the pole. When the first motor 21 is started, the output shaft of the first motor 21 reciprocates and extends, driving the top plate 23 to move up and down through the first spring 22 fixed at both ends. The top plate 23 is fixedly connected to the bottom end of the spiral guide rib 24, thereby pulling the spiral guide rib 24 to slide back and forth in the mounting groove on the inner wall of the centrifuge cylinder 35. At the same time, the first spring 22 always maintains elastic deformation during the movement, and can adaptively adjust the clamping force between the spiral guide rib 24 and the concrete according to the changes in centrifugal speed and concrete density, so as to avoid damage to the concrete aggregate or wear of the spiral guide rib 24 caused by rigid contact.

[0044] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
