Description

Technical Field

[0001] This invention relates to the field of cement pole manufacturing technology, specifically to a centrifugal molding device and molding method for manufacturing high-strength cement poles. Background Technology

[0002] Cement poles are hollow columnar components made primarily of steel bars and concrete through a centrifugal molding process. During production, a mold containing a steel reinforcement skeleton is placed on a centrifuge and rotated while concrete material is fed into the mold. Under the action of centrifugal force, the material adheres tightly to the inner wall of the mold to form a dense tube.

[0003] To improve wall thickness uniformity, existing technologies have developed centrifugal fabric feeding devices with real-time detection functions. For example, patent CN122401637A discloses a device that uses a detection component at the end of the feeding rod to contact the material surface and uses a pressure sensor to sense the reaction force to determine whether the fabric thickness at the current position meets the standard, and replenishes the material if it is insufficient.

[0004] However, the above-mentioned existing technologies still have inconveniences in practical applications. Before the detection component works, it is necessary to read the mold model through the short-range communication module and then retrieve the corresponding preset wall thickness parameters. This relies on manual selection and confirmation. When frequently changing molds of different specifications, the operation is cumbersome and there is a risk of batch scrapping due to selecting the wrong model. In addition, the detection head is prone to stains due to long-term contact with wet slurry, which affects the accuracy of subsequent detection. Summary of the Invention

The automatic positioning mechanism is located inside the transmission rod and includes a push rod. And an automatic reversing mechanism, which can change the function of the push rod, wherein the automatic reversing mechanism is set inside the automatic positioning mechanism.

[0007] As a further description of the above technical solution: the automatic positioning mechanism includes an electric push rod, which is fixedly connected to the conveying rod. A slip ring is fixedly connected to the extended end of the electric push rod, and the slip ring is slidably disposed within the conveying rod. An insert rod is abutted at the end of the slip ring away from the electric push rod. A slider is sleeved on the outer side of the insert rod, and the slider is horizontally slidably disposed within the conveying rod. A rotating rod is rotatably disposed at the end of the slider away from the insert rod. A torsion spring is fixedly connected between the outer wall of the central shaft on the rotating rod and the slider. A rotating rod is fixedly disposed at the end of the rotating rod away from the slider. A retaining ring is connected to the conveying rod, which is rotatably mounted inside the conveying rod. A top rod abuts against the outer wall of the retaining ring and the rotating rod. A rotating column is rotatably mounted inside the retaining ring and the rotating rod. A fixed sleeve is fixedly connected inside the conveying rod. A lifting block is slidably mounted inside the fixed sleeve. A spring is fixedly connected between the lifting block and the fixed sleeve. A ball bearing is rotatably mounted at one end of the lifting block that extends outside the fixed sleeve. A squeezing rod is fixedly connected to the bottom end of the lifting block. The squeezing rod is inserted into the fixed sleeve and the conveying rod. The bottom end of the squeezing rod is slidably mounted on the outer wall of the slider.

[0008] As a further description of the above technical solution: the automatic reversing mechanism includes a second magnetic block, which is fixedly connected to the outer wall of the ball bearing and rotatably disposed within the lifting block. A rotating plate is inserted at the bottom end of the lifting block, and one end of the rotating plate extending outside the lifting block is rotatably disposed within a fixed sleeve. A third magnetic block is fixedly connected to the outer wall of the rotating column near the slider. A first magnetic plate is disposed at the end of the rotating plate near the second magnetic block, and a second magnetic plate is disposed at the end of the rotating plate near the rotating rod.

[0009] As a further description of the above technical solution: several centrifugal wheels are arranged along the length direction of the transmission rod.

[0010] As a further description of the above technical solution: two top rods are provided symmetrically.

[0011] As a further description of the above technical solution: the end of the top rod extending outside the conveying rod is provided with a scraping end and a measuring end, the scraping end and the measuring end are arranged adjacent to each other, and the measuring end is provided with a sensor.

[0012] As a further description of the above technical solution: the insertion rod and the magnetic block generate a repulsive force.

[0013] As a further description of the above technical solution: an attractive force is generated between the magnetic block three and the magnetic plate two, and an attractive force is generated between the magnetic plate one and the magnetic block two.

[0014] Furthermore, the present invention adopts the following technical solution: a molding method for a centrifugal molding device for manufacturing high-strength cement poles, comprising the following steps: S1. First, set the extension amount of the electric push rod according to the required thickness of the cement, and then insert the conveying rod into the mold. S2. Cement is introduced into the mold cavity through the center hole of the conveyor rod. At this time, the motor is started and the mold rotates, causing the scraping end to move towards the inside of the mold and rotate relative to the inner wall of the mold, which can make the cement be spread more evenly when it is introduced. S3. When the ejector rod moves to the innermost part of the mold, stop the movement of the conveyor rod and the introduction of cement. After a period of centrifugal operation, the conveyor rod drives the ejector rod to be pulled outward.

[0015] This invention provides an improved centrifugal molding apparatus and method for manufacturing high-strength cement poles, which has the following improvements and advantages compared with the prior art: Firstly, through components such as balls, lifting blocks, and sliders in the automatic positioning mechanism, the extension degree of the ejector pin can be adaptively adjusted according to the inner diameter of the mold. There is no need to manually read or preset the mold model. Only the fixed extension amount of the electric push rod needs to be set to be compatible with molds of different diameters. This greatly simplifies the operation process, avoids the risk of batch scrapping due to incorrect selection, and significantly improves production flexibility and reliability. Secondly, by utilizing the magnetic linkage design of the automatic reversing mechanism, the ejector rod automatically switches to face the inner wall when it is inserted into the mold, achieving uniform material distribution. During the extraction process, the reverse rotation of the ball drives the rotating plate, magnetic block, and rotating column to move, causing the measuring end to automatically turn to the inner wall to complete the wall thickness detection. This mechanical automatic reversing structure does not require additional sensors or electronic control components, and has a rapid response. It not only ensures the uniformity of cement laying but also achieves real-time thickness monitoring. Furthermore, the scraping and detection functions are integrated into the same ejector rod, resulting in a compact structure and low cost. Thirdly, when the top rod is pulled out of the mold, the measuring end is reset by the rotation of the rotating rod. The cement slurry remaining on its surface is automatically thrown off under the action of centrifugal force and its own rotation. There is no need for regular manual cleaning, which effectively avoids the interference of wet slurry adhesion on the subsequent detection accuracy. At the same time, it also reduces the frequency of maintenance, extends the service life of the device, and ensures the consistency of long-term operation. In summary, this invention addresses the shortcomings of existing centrifugal molding devices in terms of mold adaptation, material uniformity, and thickness detection. Through the ingenious combination of an automatic positioning mechanism and an automatic reversing mechanism, it achieves adaptive adjustment of the mold diameter, automatic switching between scraping and detection functions, and self-cleaning of residues. The overall solution significantly improves the automation level of cement pole manufacturing, reduces the risk of manual intervention and misoperation, and ensures product quality stability. It has high engineering practical value and promising prospects for promotion. Attached Figure Description

[0018] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific illustrations. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Please see Figure 1 - Figure 8 This invention provides a technical solution: a centrifugal molding device for manufacturing high-strength cement poles, comprising a mold 1, a conveying rod 6 inserted inside the mold 1, a centrifugal wheel 2 abutting against the outer wall of the mold 1, a transmission rod 3 fixedly connected to the center of the centrifugal wheel 2, a motor 5 provided on one side of the transmission rod 3, and a transmission belt 4 connecting the output shaft of the motor 5 and the outer wall of the transmission rod 3, and further comprising: The automatic positioning mechanism 7 can automatically adapt to molds 1 of different diameters. The automatic positioning mechanism 7 is set inside the transmission rod 3 and includes an ejector rod 74. And an automatic reversing mechanism 8, which can change the function of the push rod 74, is located inside the automatic positioning mechanism 7.

[0020] Several centrifugal wheels 2 are arranged along the length of the transmission rod 3.

[0021] Specifically, through components such as the ball bearing 78, lifting block 77, and slider 710 in the automatic positioning mechanism 7, the extension degree of the push rod 74 can be adaptively adjusted according to the inner diameter of the mold 1. There is no need to manually read or preset the mold 1 model. Only the fixed extension amount of the electric push rod 71 needs to be set to be compatible with molds 1 of different diameters. This greatly simplifies the operation process, avoids the risk of batch scrapping due to incorrect selection, and significantly improves production flexibility and reliability.

[0022] With the help of the magnetic linkage design of the automatic reversing mechanism 8, the ejector rod 74 automatically switches to the scraping end 715 facing the inner wall when it is inserted into the mold 1, so as to achieve uniform material distribution. During the extraction process, the ball bearing 78 rotates in the opposite direction, which drives the rotating plate 82, the magnetic block 83 and the rotating column 713 to move, so that the measuring end 716 automatically turns to the inner wall to complete the wall thickness detection. This mechanical automatic reversing structure does not require additional sensors or electronic control components, and responds quickly. It not only ensures the uniformity of cement laying, but also realizes real-time thickness monitoring. Moreover, the scraping and detection functions are integrated into the same ejector rod 74, which is compact and low in cost.

[0023] When the push rod 74 is pulled out of the mold 1, the measuring end 716 is reset by the rotation of the rotating rod 75. The cement slurry remaining on its surface is automatically thrown off by centrifugal force and its own rotation. There is no need for regular manual cleaning, which effectively avoids the interference of wet slurry adhesion on the accuracy of subsequent detection. It also reduces the frequency of maintenance, extends the service life of the device, and ensures the consistency of long-term operation.

[0024] In another embodiment of the present invention, the automatic positioning mechanism 7 includes an electric push rod 71, which is fixedly connected to the conveying rod 6. A slip ring 72 is fixedly connected to the extended end of the electric push rod 71. The slip ring 72 is slidably disposed within the conveying rod 6. An insert rod 712 is abutted at the end of the slip ring 72 away from the electric push rod 71. A slider 710 is sleeved on the outer side of the insert rod 712. The slider 710 is horizontally slidably disposed within the conveying rod 6. A rotating rod 75 is rotatably disposed at the end of the slider 710 away from the insert rod 712. A torsion spring 714 is fixedly connected between the outer wall of the central shaft on the rotating rod 75 and the slider 710. A rotating rod 75 is fixedly connected to the end of the rotating rod 75 away from the slider 710. A retaining ring 76 is rotatably disposed inside the conveying rod 6. A top rod 74 abuts against the outer wall of the retaining ring 76 and extends to the outside of the conveying rod 6. A rotating column 713 is rotatably disposed inside the retaining ring 76 and the rotating rod 75. A fixed sleeve 73 is fixedly connected inside the conveying rod 6. A lifting block 77 is slidably disposed inside the fixed sleeve 73. A spring 79 is fixedly connected between the lifting block 77 and the fixed sleeve 73. A ball bearing 78 is rotatably disposed at one end of the lifting block 77 that extends outside the fixed sleeve 73. A squeezing rod 711 is fixedly connected to the bottom end of the lifting block 77. The squeezing rod 711 is inserted into the fixed sleeve 73 and the conveying rod 6. The bottom end of the squeezing rod 711 is slidably disposed on the outer wall of the slider 710.

[0025] Two top rods 74 are symmetrically arranged.

[0026] The top rod 74 extends to the end of the conveying rod 6 and is provided with a scraping end 715 and a measuring end 716. The scraping end 715 and the measuring end 716 are arranged adjacent to each other, and a sensor is provided on the measuring end 716.

[0027] A repulsive force is generated between the insertion rod 712 and the magnetic block 717.

[0028] Specifically, through components such as the ball bearing 78, lifting block 77, and slider 710 in the automatic positioning mechanism 7, the extension degree of the push rod 74 can be adaptively adjusted according to the inner diameter of the mold 1. There is no need to manually read or preset the mold 1 model. Only the fixed extension amount of the electric push rod 71 needs to be set to be compatible with molds 1 of different diameters. This greatly simplifies the operation process, avoids the risk of batch scrapping due to incorrect selection, and significantly improves production flexibility and reliability.

[0029] In another embodiment of the present invention, the automatic reversing mechanism 8 includes a second magnetic block 81, which is fixedly connected to the outer wall of the ball bearing 78 and rotatably disposed within the lifting block 77. A rotating plate 82 is inserted into the bottom end of the lifting block 77, and one end of the rotating plate 82 extending outside the lifting block 77 is rotatably disposed within the fixed sleeve 73. A third magnetic block 83 is fixedly connected to the outer wall of the rotating column 713 near the slider 710. A first magnetic plate 84 is disposed at the end of the rotating plate 82 near the second magnetic block 81, and a second magnetic plate 85 is disposed at the end of the rotating plate 82 near the rotating rod 75.

[0030] There is an attraction between magnetic block 3 83 and magnetic plate 2 85, and an attraction between magnetic plate 1 84 and magnetic block 2 81.

[0031] Specifically, with the help of the magnetic linkage design of the automatic reversing mechanism 8, the ejector rod 74 automatically switches to the scraping end 715 facing the inner wall when it is inserted into the mold 1, so as to achieve uniform material distribution. During the extraction process, the ball bearing 78 rotates in the opposite direction, which drives the rotating plate 82, the magnetic block 83 and the rotating column 713 to move, so that the measuring end 716 automatically turns to the inner wall to complete the wall thickness detection. This mechanical automatic reversing structure does not require additional sensors or electronic control components, and responds quickly. It not only ensures the uniformity of cement laying, but also realizes real-time thickness monitoring. Moreover, the scraping and detection functions are integrated into the same ejector rod 74, which is compact and low in cost.

[0032] When the push rod 74 is pulled out of the mold 1, the measuring end 716 is reset by the rotation of the rotating rod 75. The cement slurry remaining on its surface is automatically thrown off by centrifugal force and its own rotation. There is no need for regular manual cleaning, which effectively avoids the interference of wet slurry adhesion on the accuracy of subsequent detection. It also reduces the frequency of maintenance, extends the service life of the device, and ensures the consistency of long-term operation.

[0033] Working principle: When using this device, first set the extension amount of the electric push rod 71 according to the required thickness of the cement. Then, insert the conveying rod 6 into the mold 1. When the conveying rod 6 just enters the inner cavity of the mold 1, the inner wall of the mold 1 will press the ball bearing 78 and the lifting block 77 downward. Then, the lifting block 77 will squeeze the extrusion rod 711, and the slider 710 will slide away from the slip ring 72. At this time, the electric push rod 71 is activated. After the extended end of the electric push rod 71 moves a fixed distance, the extended end of the electric push rod 71 will drive the slip ring 72 to squeeze the insertion rod 712. After 712 moves toward the side of magnetic block 717, due to the repulsive force, magnetic block 717 drives the rotating rod 75 to rotate clockwise, causing the scraping end 715 to move toward the inner wall of mold 1. When the conveying rod 6 is gradually inserted into the inner cavity of mold 1, cement is introduced into the inner cavity of mold 1 from the center hole of the conveying rod 6. At this time, the motor 5 is started. Through the transmission of motor 5, transmission belt 4, transmission rod 3, centrifugal wheel 2 and mold 1, mold 1 is rotated, so that the scraping end 715 moves toward the inside of mold 1 while rotating relative to the inner wall of mold 1, which can make the cement be laid more evenly when it is introduced. When the push rod 74 moves to the innermost part of the mold 1, the movement of the conveying rod 6 and the introduction of cement are stopped. After a period of centrifugal operation, the conveying rod 6 drives the push rod 74 to be pulled outward. At this time, the ball bearing 78 is subjected to the sliding friction of the inner wall of the mold 1, causing the upper ball bearing 78 to rotate counterclockwise, thereby causing the second magnetic block 81 to move away from the first magnetic plate 84 at the upper end of the rotating plate 82. The second magnetic block 81 will drive the first magnetic plate 84 and the rotating plate 82 to rotate. The rotating plate 82 will drive the second magnetic plate 85 to rotate. Due to the attraction, the second magnetic plate 85 will drive the third magnetic block 83 and the rotating column 713 to rotate, so that the measuring end 716 faces the inner wall of the mold 1. The sensor on the measuring end 716 moves to the corresponding position and can detect whether the cement thickness meets the standard. If it does not meet the standard, the computer controls the conveying rod 6 to introduce cement into the corresponding position again and perform subsequent detection again, repeating in sequence. It should be noted that when the rotating column 713 rotates, and the measuring end 716 is squeezed by the inner wall of the cement, the rotating rod 75 can rotate slightly because there is a gap between the magnetic block 717 and the insertion rod 712. Due to the design of the push rod 74 and the ball bearing 78, when the conveying rod 6 is inserted into the inner cavity of the mold 1 and cement is introduced, the ball bearing 78 and the lifting block 77 are pressed downwards, which allows the slider 710 to drive the insert rod 712 further away from the slip ring 72. The smaller the inner diameter of the mold 1, the less the electric push rod 71's extended end squeezes the insert rod 712, and the smaller the rotation angle of the rotating rod 75. By pre-setting the fixed extension distance of the electric push rod 71, it is possible to quickly inject and test without knowing the model of the mold 1. When testing, the ball bearing 78 rotates in the opposite direction, causing the measuring end 716 and the scraping end 715 to switch positions, so that the function of the push rod 74 automatically changes from laying to testing. When the push rod 74 rotates back to its original position, the residue on the push rod 74 will be automatically thrown off without manual cleaning.

[0034] A method for manufacturing high-strength cement poles using a centrifugal molding apparatus includes the following steps: S1. First, set the extension amount of the electric push rod 71 according to the required thickness of the cement, and then insert the conveying rod 6 into the mold 1. S2. Cement is introduced into the inner cavity of mold 1 through the center hole of conveying rod 6. At this time, motor 5 is started and mold 1 rotates, so that scraping end 715 moves towards the inside of mold 1 while rotating relative to the inner wall of mold 1, which can make the cement be laid more evenly when it is introduced. S3. When the ejector rod 74 moves to the innermost part of the mold 1, stop the movement of the conveyor rod 6 and the introduction of cement. After a period of centrifugal operation, the conveyor rod 6 drives the ejector rod 74 to be pulled outward.
