Abstract
Description
Technical Field
[0001] This invention relates to the field of cement pole production technology, specifically to a cement pole feeding device and feeding method. Background Technology
[0002] Cement poles are widely used infrastructure components in fields such as power and communications, and centrifugal molding is a key process in their production. In the centrifugal process, the cement pole mold rotates at high speed, causing the concrete to be evenly distributed on the inner wall of the mold under centrifugal force, forming the pole's structure. However, in actual production, problems such as uneven concrete distribution, localized material shortages, and insufficient density often occur, especially at the pole's ends and diameter transition sections, where defects such as voids and honeycombing are prone to appear, severely affecting the pole's mechanical properties and service life.
[0003] Traditional automatic feeding methods are divided into feeding before centrifugation and feeding during centrifugation. Feeding before centrifugation is generally done manually, which is time-consuming and labor-intensive and cannot control the amount of feeding well. Therefore, the current feeding method is generally to automatically feed during centrifugation. As the cement slurry inside the mold is subjected to centrifugal force, it will be squeezed onto the inner wall of the mold, making the outer ring of the formed cement pole tight and smooth. However, uneven feeding will occur on the inner wall of the formed cement pole, which requires feeding from the center.
[0004] Existing centrifugal feeding devices generally use a single tube for feeding, but conventional single-tube feeding devices have poor feeding uniformity, making it difficult to guarantee feeding quality. Furthermore, some existing feeding devices can only achieve simple feeding, and problems such as material accumulation, backflow, material splashing, and blockage are prone to occur during the feeding process. At the same time, they cannot achieve uniform and continuous feeding under centrifugal conditions, making it difficult to meet the production requirements of high-quality cement poles.

[0015] Beneficial effects Compared with the prior art, the present invention provides a cement pole replenishing device and its replenishing method, which has the following beneficial effects: 1. The cement pole feeding device and its feeding method utilize a double-auger reverse feeding design. The feeding auger outside the transmission pipe conveys the material in the feeding box forward, while the internal return auger rotates in the opposite direction to the feeding auger, allowing excess material in the feeding pipe to flow back to the feeding box. This prevents material accumulation and blockage, achieves material recycling, and ensures a stable feeding rate. In addition, the feeding auger and return auger mix the cement slurry from the feeding box during operation, preventing stratification and sedimentation caused by long-distance transport of the cement slurry.
[0016] 2. The cement pole feeding device and its feeding method, wherein the first guide blade set on the conical seat at the front end of the feeding pipe can evenly guide the material to the inclined discharge port during the rotation of the feeding pipe, and together with the baffle plate, the material is accurately sprayed onto the inner wall of the mold, avoiding material splashing and improving the uniformity of feeding. In addition, the second guide blade, together with the conical inlet at the front end of the transmission pipe, can improve the effect of quickly transporting excess cement slurry from the inside front end of the feeding pipe to the inside of the transmission pipe, while reducing the problem of end blockage during material conveying.
[0017] 3. The cement pole feeding device and its feeding method can move synchronously with the feeding pipe through the support component, providing stable support for the long feeding pipe and avoiding deformation of the feeding pipe; the feeding pipe and the transmission pipe are driven by independent motors, which can be adapted to the feeding needs of cement poles of different specifications.

[0020] 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.
[0021] Example 1 Please see Figures 1 to 10 The present invention provides a technical solution: a cement pole replenishing device, including a fixed slide rail 1, an electric slide block 2 installed on the fixed slide rail 1, and a replenishing box 3 set on the electric slide block 2. The front end of the replenishing box 3 is tapered, and a filling port 4 is provided on the replenishing box 3. A feeding pipe 6 is rotatably connected to the front end of the replenishing box 3. An end sealing stop 28 is provided at the tail end of the replenishing box 3. A transmission pipe 13 is rotatably connected to the center of the end sealing stop 28. A support assembly is provided on the fixed slide rail 1. A motor base 29 is provided on the electric slide block 2. A first reduction motor 5 and a second reduction motor 8 are installed on the motor base 29. The first reduction motor 5 is connected to the end of the transmission pipe 13. A drive wheel 9 is installed at the end of the second reduction motor 8. A transmission wheel 7 is installed on the outer wall of the feeding pipe 6. The drive wheel 9 is connected to the transmission wheel 7. The end of the transmission pipe 13 is inserted into the inside of the feeding pipe 6. A conical auger 14 and a feeding auger 15 are provided on the outside of the transmission pipe 13. The conical auger 14 is located inside the feeding box 3, and the feeding auger 15 is located on the outer wall of the feeding pipe 6. The front end of the feeding pipe 6 is provided with a discharge port 10. A baffle plate 11 is installed on the outer wall of the front end of the feeding pipe 6. The baffle plate 11 is located outside the discharge port 10. The discharge port 10 is inclined. An inner wall scraper 12 is installed on the outer wall of the feeding pipe 6. The inner wall scraper 12 is located on one side of the baffle plate 11. The diameter of the inner wall scraper 12 is larger than the diameter of the baffle plate 11. A centrifugal mechanism 27 is provided at the end of the fixed slide rail 1. A cement pole mold 26 is provided on the centrifugal mechanism 27. The cement pole mold 26 and the feeding pipe 6 are coaxially arranged. Limiting clamps are provided at both ends of the cement pole mold 26.
[0022] The support assembly includes a sliding seat 22, an electric push rod 23, and an arc-shaped support seat 24, which are disposed on the fixed slide rail 1. A groove 21 is provided on the surface of the fixed slide rail 1. The sliding seat 22 slides inside the groove 21. The electric push rod 23 is disposed inside the groove 21, and the output end of the electric push rod 23 is connected to one side of the sliding seat 22. The arc-shaped support seat 24 is installed on the top of the sliding seat 22. An abutting ball 25 is provided on the arc-shaped support seat 24, and the abutting ball 25 abuts against the outer wall of the feeding pipe 6.
[0023] Specifically, during the production of cement poles, the ring-shaped steel reinforcement cage is first placed into the cement pole mold 26. Then, cement concrete is filled into the lower mold of the cement pole mold 26. Next, the upper mold of the cement pole mold 26 is installed on the lower mold, and then it is placed into the centrifugal mechanism 27 for centrifugation. During centrifugation, the cement concrete inside the mold is subjected to centrifugal force and is thrown against the inner wall of the mold, making the outer ring of the formed cement pole tight and smooth. However, the inner wall of the formed cement pole may sometimes show uneven distribution of cement concrete. Therefore, a feeding device is needed to feed the material during the centrifugation process.
[0024] The feeding mechanism in this application is located on one side of the centrifugal mechanism 27, and the feeding pipe 6 is coaxial with the cement pole mold 26 located on the centrifugal mechanism 27. When the centrifugal mechanism 27 is in operation, the cement pole mold 26 rotates, and the aggregate inside the cement pole mold 26 is thrown against the inner wall of the cement pole mold 26 by centrifugal force. When the aggregate inside the cement pole mold 26 has not completely solidified, a feeding operation is required to ensure that the inner wall of the formed cement pole is smooth and evenly distributed.
[0025] During material replenishment, this application injects cement slurry (containing only cement) into the filling port 4 of the material replenishment box 3, and then activates the electric slide block 2 to slide on the fixed slide rail 1 (the electric slide block 2 and the fixed slide rail 1 are existing electric slide rail structures, which will not be described in detail here), so that the feeding pipe 6 installed at the front end of the material replenishment box 3 is inserted into the cement pole mold 26. In addition, in order to prevent the feeding pipe 6 from bending due to its own weight during the feeding process, this application sets a support component on the fixed slide rail 1, and supports the feeding pipe 6 by the abutting ball bearing 25 on the support component, without affecting the movement and rotation of the feeding pipe 6. When the feeding pipe 6 is inserted into the cement pole mold 26, the first reduction motor 5 and the second reduction motor 8 are started. The first reduction motor 5 drives the transmission pipe 13 to rotate, and the second reduction motor 8 drives the feeding pipe 6 to rotate through the drive wheel 9 and the transmission wheel 7. The feeding pipe 6 continues to move forward with the movement of the electric slide block 2. When the end of the feeding pipe 6 is inserted into the cement pole mold 26, the first reduction motor 5 drives the transmission pipe 13 to rotate, so that the conical auger 14 transports the cement slurry into the feeding pipe 6. Then, the feeding auger 15 pushes the cement slurry to the front end of the feeding pipe 6 and then discharges it through the discharge port 10. The feeding pipe 6 is driven by the second reduction motor 8, the drive wheel 9 and the transmission wheel 7, so that the feeding pipe 6 rotates, thereby causing the cement slurry discharged through the discharge port 10 to be quickly thrown onto the inner wall of the cement pole in the cement pole mold 26. In addition, the baffle plate 11 prevents the cement slurry from splashing when it is thrown out. Furthermore, the inner wall scraper 12, which is spirally arranged, is installed on the outer wall of the feeding pipe 6. When the feeding pipe 6 rotates and moves, it can scrape the cement slurry adhering to the inner wall of the cement pole, complete the material replenishment process, improve the smoothness of the inner wall of the cement pole after molding, and thus improve the molding quality of the cement pole.
[0026] Example 2 As one embodiment of the present invention, please refer to Figure 4 , Figure 5 and Figure 8 Based on Embodiment 1, this application further includes that the tail end of the transmission pipe 13 is tapered, the tail end of the tapered auger 14 is rotatably connected to the end sealing seat 28, a pressure relief groove 131 is provided on the outer wall of the transmission pipe 13, the tapered auger 14 is provided at the front tapered part of the feeding box 3, the edge of the feeding auger 15 abuts against the inner wall of the feeding pipe 6, and a tapered feed inlet 20 is provided at the front end of the transmission pipe 13. A return auger 16 is provided on the inner wall of the transmission pipe 13. The return auger 16 rotates in the opposite direction to the feeding auger 15. A pressure relief groove 131 is provided on the outer wall of the transmission pipe 13. A return port 132 is provided at the tail of the transmission pipe 13. The tail of the feeding pipe 6 is tapered.
[0027] Specifically, during the feeding process, the transmission pipe 13 rotates under the drive of the first reduction motor 5. During the rotation of the transmission pipe 13, the cement slurry is first squeezed from the feeding box 3 into the feeding pipe 6 through the conical auger 14. The pressure relief groove 131 on the transmission pipe 13 can help relieve pressure and prevent excessive slurry from damaging the blades of the auger during squeezing. Then, the cement slurry is stably conveyed forward by the feeding auger 15 on the outer wall of the transmission pipe 13, and the feeding is uniform. When the cement slurry is conveyed to the end of the transmission pipe 13, it is squeezed and centrifuged by the rotation of the feeding pipe 6, so that the cement slurry is stably discharged from the discharge port 10 on the outer wall of the feeding pipe 6. To ensure stable discharge from discharge port 10 and prevent emptying, the discharge volume of discharge port 10 is generally less than the feeding volume of conical auger 14. This causes cement slurry to easily accumulate at discharge port 10, resulting in blockage of discharge port 10 and excessive pressure at the end of feeding pipe 6. To solve this problem, this application uses a return auger 16 arranged in the opposite direction to the feeding auger 15 inside the transmission pipe 13, and sets a conical inlet 20 to enlarge the end diameter of the transmission pipe 13. This allows the cement slurry accumulated at discharge port 10 to be quickly transported back to the end of the transmission pipe 13 through the conical inlet 20 and the return auger 16. Then, it returns to the feed box 3 from the return port 132 opened at the end of the transmission pipe 13 to mix with the cement slurry in the feed box 3. This method can reduce the pressure at discharge port 10 and prevent cement slurry from accumulating and solidifying. Another advantage of this method is that when the returned cement slurry is mixed with the cement slurry in the replenishment box 3, it can prevent the cement slurry from separating in the replenishment box 3 and prevent the cement slurry from solidifying, thereby improving the mixing degree and fluidity of the cement slurry.
[0028] Example 3 As an embodiment of the present invention, based on embodiment 2, this application further includes a conical seat 17 disposed on the inner wall of the end of the feeding pipe 6. The conical seat 17 is disposed on one side of the discharge port 10. A first guide blade 18 and a second guide blade 19 are disposed on the conical seat 17. The first guide blade 18 is disposed at the edge of the conical seat 17, and the second guide blade 19 is disposed inside the first guide blade 18. Both the first guide blade 18 and the second guide blade 19 are S-shaped. The bending directions of the first guide blade 18 and the second guide blade 19 are opposite, and the first guide blade 18 and the second guide blade 19 are intersecting. A conical feed inlet 20 is located on one side of a conical seat 17, and a gap is provided between the conical feed inlet 20 and the conical seat 17. A second guide blade 19 is located between the conical feed inlet 20 and the conical seat 17.
[0029] Specifically, to ensure the stability of material discharge and return, this application provides a conical seat 17 on the inner wall of the end of the feeding pipe 6. The first guide blade 18 and the second guide blade 19 provided on the conical seat 17 can guide the cement slurry while the transmission pipe 13 rotates. The bending direction of the first guide blade 18 is consistent with the tilting direction of the discharge port 10, so that the first guide blade 18 can disperse the cement slurry to the edge, so that the first guide blade 18 can smoothly discharge the cement slurry from the discharge port 10. The bending direction of the second guide blade 19 is opposite to that of the first guide blade 18, so the second guide blade 19 can bring the cement slurry blades closer to the center. Since the conical feed port 20 of the transmission pipe 13 is provided at the center, the second guide blade 19 can accelerate the speed at which excess cement slurry is introduced into the conical feed port 20. Therefore, the conical seat 17, the first guide blade 18 and the second guide blade 19 provided in this application can improve the discharge stability and return stability of cement slurry, reduce the probability of blockage, and thus improve the stable operation capability of the feeding device.
