Description

Technical Field

[0001] This invention relates to the field of cement pole production technology, specifically to a cement casting molding equipment for cement poles. Background Technology

[0002] In the production of cement utility poles, casting is typically used. Existing equipment often uses fixed molds, requiring manual dismantling of each side mold. This is labor-intensive, inefficient, and can easily damage the pole's surface, affecting the product's appearance. Furthermore, casting often relies on single-point mixing devices, limiting the flexibility of switching casting positions and potentially leading to concrete segregation or insufficient compaction.

[0003] In addition, the molds are often fixed by simple binding or bolt tightening during the casting process, which is not stable enough and takes a long time to disassemble and assemble. Vibration compaction methods are also often lacking, which may lead to defects such as honeycomb and pitting inside the finished utility poles, reducing the structural strength and durability. Summary of the Invention

[0004] The purpose of this invention is to provide a cement casting and molding equipment for cement utility poles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cement casting and molding device for cement utility poles, comprising a bearing plate, multiple utility pole molds, multiple demolding connecting plates, an arc-shaped moving component, a rotating bearing plate, and multiple mixing tanks. The bearing plate is a regular polygonal plate; the multiple utility pole molds are arranged in a circular array, forming a columnar mold, and sealing gaskets are provided at the joints of the multiple utility pole molds; the multiple demolding connecting plates are fixedly connected to the utility pole molds on their respective sides; the moving end of the arc-shaped moving component is fixedly connected to the demolding connecting plate, and its bottom end is fixedly mounted on the bearing plate; the rotating bearing plate is positioned above the utility pole molds; the multiple mixing tanks are arranged in a circular array around the central axis of the rotating bearing plate, and the rotating bearing plate drives the multiple mixing tanks to rotate around the central axis, allowing the multiple mixing tanks to perform spiral casting.

[0006] According to the cement casting equipment for cement poles provided by the above technical solution, the bearing plate is a regular polygonal plate, providing stable support for the entire equipment. Multiple pole molds are arranged in a circular array on the bearing plate. The inner sidewalls of each pole mold are aligned to form a complete columnar mold cavity. Sealing gaskets are sandwiched at the joints of adjacent pole molds. The sealing gaskets are forced to deform by the clamping force of the demolding connecting plate, ensuring that the mold cavity is tight and leak-proof during casting. The outer side of each pole mold is fixedly connected to the corresponding demolding connecting plate through a connector. The bottom end of the arc-shaped moving component is fixed to the bearing plate, and its moving end is fixedly connected to the demolding connecting plate. Through the extension and retraction of the arc-shaped moving component along a preset arc trajectory, multiple demolding connecting plates can synchronously drive the connected pole molds to reciprocate radially, realizing the rapid closing and opening of the molds, significantly shortening the demolding cycle and protecting the integrity of the pole surface. A rotating support plate is positioned directly above the utility pole mold and can rotate relative to it around its vertical central axis. Multiple mixing drums are arranged in a circular array around the central axis of the rotating support plate and rotate synchronously with it. The mixing drums are responsible for the continuous mixing and temporary storage of the cement slurry, and each has a discharge pipe equipped with a manual valve at its lower part. During casting, the rotating support plate drives the multiple mixing drums to rotate around the central axis. The discharge port sequentially passes through the annular area at the top of the columnar mold along a circular trajectory. The slurry is injected into the mold cavity at the continuously moving discharge point, thus forming a spiral distribution path inside the mold cavity. This spiral casting method allows the slurry to spread layer by layer along the circumference of the mold cavity, effectively reducing voids and air bubbles, and improving the density and uniformity of the utility pole blank. Simultaneously, combined with multi-drum circulating feeding, continuous casting without stopping the machine is achieved, significantly improving molding efficiency and product quality.

[0007] In the above technical solution, preferably, the support plate consists of a fixed platform located on the outer ring and a rotating demolding platform located on the inner ring, with multiple utility pole molds located on the rotating demolding platform on the inner ring, and the arc-shaped moving component located on the fixed platform on the outer ring.

[0008] In this technical solution, the support plate consists of an outer ring fixed platform and an inner ring rotating demolding platform. The fixed platform provides the main support foundation for the equipment. The inner ring rotating demolding platform is rotatably embedded in the fixed platform. Multiple utility pole molds are evenly placed on the inner ring rotating demolding platform, so that the mold as a whole can rotate together with the rotating demolding platform. The arc-shaped moving component is fixedly installed on the outer ring fixed platform.

[0009] In the above technical solution, preferably, an installation frame is provided below the fixed platform, and a first drive motor is installed below the installation frame. The drive end of the first drive motor drives the rotary demolding table to rotate.

[0010] In this technical solution, a first drive motor is fixedly installed below the mounting frame via a connector. The drive end of the first drive motor is connected to the central transmission of the rotary demolding table, thereby driving the rotary demolding table to rotate around its own axis. During demolding, the rotary demolding table drives the utility pole mold and the formed utility pole to rotate together, causing circumferential sliding and loosening between the blank and the mold wall. Combined with the radial disengagement action of the arc-shaped moving component, this significantly reduces demolding resistance, further protects the integrity of the utility pole surface, and improves demolding efficiency.

[0011] In the above technical solution, preferably, a number of support legs are provided below the fixed platform, and rubber support pads are installed at the bottom of the support legs.

[0012] In this technical solution, the rubber support pad can not only buffer the impact and vibration during equipment operation to ensure stable operation, but also prevent rigid friction between the support legs and the ground, reduce noise and extend service life.

[0013] In the above technical solution, preferably, multiple pairs of fixing hoops are fitted around the periphery of multiple pole molds, each pair of fixing hoops is locked by a threaded rod and a locking nut, and each pair of fixing hoops clamps the pole mold by an arc-shaped clamping groove on its clamping surface.

[0014] In this technical solution, after the utility pole molds are closed to form a columnar mold cavity, in order to further enhance the overall closing rigidity and sealing of the mold, multiple pairs of fixing hoops are fitted around the periphery of the multiple utility pole molds. Each pair of fixing hoops is locked by a threaded rod and a locking nut. Each pair of fixing hoops has an arc-shaped clamping groove on its clamping surface that matches the shape of the outer wall of the mold. The arc-shaped clamping groove firmly clamps the utility pole mold, so that the sealing gasket at the joint of adjacent molds is fully compressed, avoiding the leakage of grout caused by the loosening of the mold cavity during pouring.

[0015] In the above technical solution, preferably, the arc-shaped moving component includes a base plate, a support plate, multiple swing arms and a hydraulic telescopic cylinder. The base plate is fixed on the bearing plate, the support plate is fixed on the base plate, one end of each of the multiple swing arms is hinged to the support plate, and the other end is hinged to the demolding connection plate. The multiple swing arms are longitudinally distributed and parallel to each other.

[0016] In this technical solution, the base plate is fixed on a fixed platform of the fixed bearing plate, and the support plate is vertically fixed on the base plate. One end of each of the multiple swing arms is hinged to a different height on the support plate, and the other end is hinged to a demolding connecting plate. The multiple swing arms are longitudinally distributed and parallel to each other. The cylinder body of the hydraulic telescopic cylinder is hinged to the support plate or the base plate, and the end of its piston rod is connected to one of the swing arms or the demolding connecting plate. When the hydraulic telescopic cylinder extends or retracts, the swing arms swing synchronously, causing the demolding connecting plate to drive the connected utility pole mold to move smoothly radially back and forth along a preset arc trajectory, realizing accurate mold closing and rapid disassembly, and ensuring the consistency and reliability of the action.

[0017] In the above technical solution, preferably, a vibration motor is installed on each of the multiple demolding connecting plates.

[0018] In this technical solution, during the pouring process, vibratory motors are installed on multiple demolding connection plates to increase the density of the concrete. When the grout is injected into the mold cavity, the vibratory motors generate high-frequency micro-amplitude vibrations, which are transmitted to the utility pole mold through the demolding connection plates. This causes the grout in the mold cavity to flow and fully fill all corners, while forcing air bubbles to rise and be expelled, effectively reducing internal voids. In synergy with the spiral pouring path, this significantly improves the density and uniformity of the utility pole blank.

[0019] In the above technical solution, preferably, a motor mounting bracket is provided above the rotating bearing plate, and a second drive motor is installed on the motor mounting bracket, which drives the rotating bearing plate to rotate.

[0020] In this technical solution, the output end of the second drive motor is connected to the center of the rotating support plate, driving the rotating support plate to rotate around its central axis. The second drive motor can be a speed-regulating motor, so as to flexibly adjust the rotation speed according to different casting processes and achieve stable and controllable spiral fabric distribution.

[0021] In the above technical solution, preferably, a plurality of bow-shaped support rods are installed on the mixing tank, a support frame is installed on the bow-shaped support rods, a third drive motor is installed on the support frame, the drive end of the third drive motor is connected to a stirring rod, the stirring rod extends into the mixing tank, and a stirring paddle is installed on the stirring rod located inside the mixing tank.

[0022] In this technical solution, a stirring rod extends downwards into the mixing tank, and a stirring paddle is installed on the stirring rod inside the mixing tank. A third drive motor drives the stirring paddle through the stirring rod to continuously stir the cement slurry in the tank, preventing sedimentation, segregation, or premature solidification, and ensuring the uniformity and flowability of the output. A discharge pipe with a manual valve is installed at the bottom of the mixing tank, allowing manual control of the discharge flow and volume during pouring. Combined with the rotation of the rotating support plate, multiple mixing tanks are used to stir sequentially, continuously feeding material into the mold cavity along a circumferential trajectory, ultimately forming a layered spiral pouring effect.

[0023] Compared with the prior art, the beneficial effects of the present invention are: by cooperating with the arc-shaped moving component and the mold disassembly connecting plate, and using the swing arm mechanism and hydraulic telescopic cylinder drive, the mold can be opened and closed automatically and synchronously, which facilitates mechanized mold disassembly, greatly reduces the intensity of manual operation, and avoids damage to the surface of the molded utility pole.

[0024] The fixed support plate is divided into an outer ring fixed platform and an inner ring rotating demolding platform. The rotating demolding platform can rotate freely under the drive of the first drive motor, which can adjust the mold position and adapt to demolding or pouring operations in different directions, thus enhancing the flexibility of the equipment.

[0025] Multiple pairs of fixing hoops are locked by threaded rods and locking nuts, and are equipped with arc-shaped clamping grooves to fit the outer circumference of the utility pole mold, ensuring the mold is stable and reliable during casting. At the same time, clamping and loosening are quick and easy, facilitating mold assembly and disassembly.

[0026] The demolding connection plate is equipped with a vibration motor, which can directly transmit vibration to the mold during the pouring process, effectively eliminating air bubbles inside the concrete and improving the density and strength of the finished product of the utility pole.

[0027] Multiple mixing tanks are arranged in a circular array on a rotating support plate, each equipped with an independent mixing device. Driven by a second motor, the support plate rotates, and the discharge port sequentially passes through the annular area at the top of the columnar mold along a circumferential trajectory. The slurry is injected into the mold cavity at the continuously moving drop point, thus forming a spiral distribution path within the mold cavity. This spiral pouring method allows the slurry to spread layer by layer along the circumference of the mold cavity, effectively reducing voids and air bubbles, and improving the density and uniformity of the utility pole blank.

[0028] With a compact overall structure and a high degree of automation, it integrates functions such as rapid mold clamping, vibration compaction, rotary casting, and convenient demolding, significantly reducing labor costs and improving the molding quality and production efficiency of utility poles.

Sealing gaskets are sandwiched at the joints of adjacent pole molds 2. The sealing gaskets are forced to deform by the clamping force of the demolding connecting plate 3, ensuring that the mold cavity is tight and leak-proof during casting. The outer side of each pole mold 2 is fixedly connected to the corresponding demolding connecting plate 3 through a connector; the bottom end of the arc-shaped moving component 4 is fixed on the bearing plate 1, and its moving end is fixedly connected to the demolding connecting plate 3. Through the extension and retraction of the arc-shaped moving component 4 along a preset arc trajectory, multiple demolding connecting plates 3 can synchronously drive the connected pole molds 2 to reciprocate radially, realizing the rapid closing and opening of the molds, significantly shortening the demolding cycle and protecting the integrity of the pole surface. A rotating support plate 5 is positioned directly above the utility pole mold 2 and can rotate relative to the support plate 1 around its vertical central axis. Multiple mixing tanks 6 are arranged in a circular array around the central axis of the rotating support plate 5 and rotate synchronously with it. The mixing tanks 6 are responsible for the continuous mixing and temporary storage of the cement slurry, and have a discharge pipe with a manual valve installed at their lower part. During the pouring operation, the rotating support plate 5 drives the multiple mixing tanks 6 to rotate around the central axis. The discharge port passes sequentially through the annular area at the top of the columnar mold along a circular trajectory. The slurry is injected into the mold cavity at the continuously moving drop point, thus forming a spiral distribution path inside the mold cavity. This spiral pouring method allows the slurry to spread layer by layer along the circumference of the mold cavity, effectively reducing voids and air bubbles, and improving the density and uniformity of the utility pole blank. Simultaneously, combined with multi-tank circulating feeding, continuous pouring without stopping the machine is achieved, significantly improving molding efficiency and product quality.

Multiple utility pole molds 2 are located on the rotating demolding platform 1-2 on the inner ring, and the arc-shaped moving component 4 is located on the fixed platform 1-1 on the outer ring.

[0035] In this embodiment, the support plate 1 consists of an outer ring fixed platform 1-1 and an inner ring rotating demolding platform 1-2. The fixed platform 1-1 provides the main support foundation for the equipment. The inner ring rotating demolding platform 1-2 is rotatably embedded in the fixed platform 1-1. Multiple utility pole molds 2 are evenly placed on the inner ring rotating demolding platform 1-2, so that the mold as a whole can rotate together with the rotating demolding platform 1-2. The arc-shaped moving component 4 is fixedly installed on the outer ring fixed platform 1-1.

[0036] In the above embodiments, preferably, as follows: Figures 1 to 2As shown, a mounting frame 7 is provided below the fixed platform 1-1, and a first drive motor 8 is installed below the mounting frame 7. The drive end of the first drive motor 8 drives the rotating demolding platform 1-2 to rotate.

[0037] In this embodiment, a first drive motor 8 is fixedly installed below the mounting frame 7 via a connector. The drive end of the first drive motor 8 is connected to the central transmission of the rotary demolding table 1-2, thereby driving the rotary demolding table 1-2 to rotate around its own axis. During demolding, the rotary demolding table 1-2 drives the utility pole mold 2, along with the formed utility pole, to rotate together, causing circumferential sliding and loosening between the blank and the mold wall. Combined with the radial disengagement action of the arc-shaped moving component 4, this significantly reduces demolding resistance, further protects the integrity of the utility pole surface, and improves demolding efficiency.

[0038] In the above embodiments, preferably, as follows: Figures 1 to 2 As shown, several support legs 9 are provided below the fixed platform 1-1, and rubber support pads 10 are installed at the bottom of the support legs 9.

[0040] In the above embodiments, preferably, as follows: Figure 1 , Figure 5 and Figure 6 As shown, multiple pairs of fixing hoops 11 are fitted around the periphery of multiple utility pole molds 2. Each pair of fixing hoops 11 is locked by a threaded rod 12 and a locking nut 13. Each pair of fixing hoops 11 clamps the utility pole mold 2 by an arc-shaped clamping groove 14 on its clamping surface.

[0041] In this embodiment, after the utility pole mold 2 is closed to form a columnar mold cavity, in order to further enhance the overall closing rigidity and sealing of the mold, multiple pairs of fixing hoops 11 are fitted around the periphery of the multiple utility pole molds 2. Each pair of fixing hoops 11 is locked by a threaded rod 12 and a locking nut 13. Each pair of fixing hoops 11 has an arc-shaped clamping groove 14 that matches the shape of the outer wall of the mold on its clamping surface.

[0043] In this embodiment, the base plate 4-1 is fixed on the fixed platform 1-1 of the fixed bearing plate 1, and the support plate 4-2 is vertically fixed on the base plate 4-1. One end of each of the multiple swing arms 4-3 is hinged to a different height on the support plate 4-2, and the other end is hinged to the demolding connecting plate 3.

The cylinder body of the hydraulic telescopic cylinder 4-4 is hinged to the support plate 4-2 or the base plate 4-1, and the end of its piston rod is connected to one of the swing arms or the demolding connecting plate 3. When the hydraulic telescopic cylinder 4-4 extends or retracts, the swing arm 4-3 swings synchronously, causing the demolding connecting plate 3 to drive the connected utility pole mold 2 to move radially back and forth smoothly along a preset arc trajectory, so as to realize the accurate closing and quick disassembly of the mold and ensure the consistency and reliability of the action.

[0044] In the above embodiments, preferably, as follows: Figure 3 As shown, a vibration motor 15 is installed on each of the multiple demolding connection plates 3.

[0045] In this embodiment, during the pouring process, in order to increase the density of the concrete, multiple demolding connection plates 3 are equipped with vibration motors 15. When the slurry is injected into the mold cavity, the vibration motors 15 generate high-frequency micro-amplitude vibrations, which are transmitted to the utility pole mold 2 through the demolding connection plates 3, causing the slurry in the mold cavity to flow and fully fill all corners, while forcing air bubbles to rise and be discharged, effectively reducing internal voids. In synergy with the spiral pouring path, this significantly improves the density and uniformity of the utility pole blank.

[0046] In the above embodiments, preferably, as follows: Figure 1 As shown, a motor mounting bracket 16 is provided above the rotating support plate 5, and a second drive motor 17 is installed on the motor mounting bracket 16.

The second drive motor 17 can be a speed-regulating motor, so as to flexibly adjust the rotation speed according to different casting processes and achieve stable and controllable spiral fabric distribution.

[0048] In the above embodiments, preferably, as follows: Figure 1 and Figure 7As shown, multiple bow-shaped support rods 18 are installed on the mixing tank 6, and a support frame 19 is installed on the bow-shaped support rods 18. A third drive motor 20 is installed on the support frame 19. The drive end of the third drive motor 20 is connected to a stirring rod 21. The stirring rod 21 extends into the mixing tank 6, and a stirring paddle 22 is installed on the stirring rod 21 located inside the mixing tank 6.

[0049] In this embodiment, the stirring rod 21 extends downward into the mixing tank 6, and a stirring paddle 22 is installed on the stirring rod 21 located inside the mixing tank 6. The third drive motor 20 drives the stirring paddle 22 through the stirring rod 21 to continuously stir the cement slurry in the tank, preventing the slurry from settling or solidifying prematurely, and ensuring the uniformity and fluidity of the output. A feed pipe with a manual valve is installed at the bottom of the mixing tank 6, which allows manual control of the discharge flow and flow rate during pouring. In conjunction with the rotation of the rotating support plate 5, multiple mixing tanks 6 are stirred sequentially, and material is continuously fed into the mold cavity along a circumferential trajectory, ultimately forming a layered spiral pouring effect.

[0050] Working Principle: In use, multiple utility pole molds 2 are assembled onto the rotating demolding platform 1-2 on the inner ring of the support plate 1 to form a columnar mold cavity. The outer periphery of the mold 2 is clamped by the arc-shaped clamping grooves 14 on multiple pairs of fixing hoops 11, and the threaded rod 12 and locking nut 13 are tightened to complete the locking. The first drive motor 8 is started to drive the rotating demolding platform 1-2 to rotate to the required working position. Before pouring, the third drive motor 20 on each mixing tank 6 drives the mixing rod 21 and mixing paddle 22 to rotate, continuously mixing the concrete. The second drive motor 17 is started to rotate the support plate 5, causing multiple mixing tanks 6 to rotate around the central axis, and the multiple mixing tanks 6 perform spiral pouring. During the pouring process, the vibration motor 15 installed on the demolding connection plate 3 is started. The vibration is transmitted to the utility pole mold 2 through the demolding connection plate 3, so that the concrete is fully filled and compacted in the mold cavity, eliminating air bubbles. After the concrete has hardened to the demolding strength, loosen all the fixing hoops 11, start the hydraulic telescopic cylinder 4-4 in the arc-shaped moving component 4, push the swing arm 4-3 to swing around the hinge point on the support plate 4-2, and the swing arm 4-3 pulls each pole mold 2 outward synchronously through the demolding connecting plate 3 hinged at the other end, so as to achieve rapid automatic demolding; at this time, the rotating demolding table 1-2 can rotate to facilitate the removal of the formed pole or the next round of operation.
