Description

Technical Field

[0001] This utility model relates to the field of cement poles, and specifically to a centrifugal rotating device for cement poles. Background Technology

[0002] The cement poles require a centrifugal molding process during processing. This process involves hoisting the pole mold onto a centrifuge and supporting it with multiple support rollers in two rows. One row of support rollers is driven by a motor to rotate at high speed, causing the concrete inside the mold to be compacted under centrifugal force.

[0003] However, in actual production, especially when the thick end of the pole mold rotates at high speed, a large amount of concrete inside splashes outwards. This splashing not only causes serious pollution to the working environment and increases cleaning and maintenance costs, but also leads to a significant waste of cement materials. More seriously, the splashed concrete slurry may affect the normal operation of the equipment and even endanger the safety of operators. Currently, conventional centrifugal equipment lacks effective protective measures and cannot solve the concrete splashing problem while ensuring production efficiency. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

A protective cover to prevent cement from splashing out of the pole mold is fixed on the lower part of the movable crossbeam. A guide and collection assembly is provided on the inner side of the protective cover.

[0007] Alternatively, the carriage includes a movable guide rail arranged along the axis of the movable guide rail support roller, and the lower part of the movable guide rail is fixedly connected by a support frame.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0018] like Figure 1 As shown, this application proposes a centrifugal rotating device for cement poles, including two rows of support rollers that are rotatably supported by multiple support shafts. The upper part of the two rows of support rollers supports a pole mold, and a slide is provided on both sides of the ends of the two support rollers. The slide supports a movable crossbeam, and a protective cover is fixed to the lower part of the movable crossbeam to prevent cement from splashing out of the pole mold. A guide and collection assembly is provided on the inner side of the protective cover.

[0019] The support rollers can be made of metal with a wear-resistant coating to extend their service life. The spacing of the support rollers can be adjusted according to the size of the pole mold, typically 0.5-1.5 meters. The carriage can use a steel frame structure and can be moved manually. The moving crossbeam can be made of I-beams or box girder structures, and its length should cover the working area of ​​the pole mold. The protective cover can be made of steel plate or plastic sheet, with a thickness of 2-5 mm, and an arc or zigzag shape to better fit the pole mold. The guide collection assembly can include multiple parallel guide strips, spaced 50-100 mm apart, and can be made of stainless steel or wear-resistant plastic.

[0020] This technical solution effectively solves the problem of concrete splashing during the centrifugal molding of cement poles by installing a movable protective device at the end of the supporting rollers. When the pole mold rotates at high speed, the moving beam drives the protective cover to cover the mold, preventing cement slurry from splashing. The guide and collection component inside the protective cover directs the splashed cement to a specific location for collection, maintaining a clean working environment and avoiding material waste. Compared with existing technologies, this device has a simple and reliable structure, and its position can be flexibly adjusted according to pole molds of different sizes, significantly improving the cleanliness of the production process and material utilization.

[0021] Furthermore, this application also proposes that the carriage includes a movable guide rail arranged along the direction of the movable guide rail support roller support axis, and the lower part of the movable guide rail is fixedly connected by a support frame.

[0022] The movable guide rail can be made of I-beams or channel steel, and its length direction is parallel to the support shaft of the support rollers. Specifically, this technical solution enables the carriage to move stably along the axis of the support rollers by setting up an axial movable guide rail structure. The fixed connection between the movable guide rail and the support frame ensures the rigidity of the overall structure and avoids deformation of the guide rail caused by vibration during centrifugation. Thus, this structure not only ensures the moving stability of the protective cover but also can withstand the dynamic loads during centrifugation. Compared with existing technologies, this solution solves the technical problem of unstable carriage movement and improves the positioning accuracy and reliability of the protective cover.

[0023] Furthermore, this application also proposes that multiple movable wheels supported on movable guide rails are provided on both sides of the movable crossbeam.

[0024] Specifically, the casters are made of wear-resistant materials, and their diameter is designed to match the dimensions of the moving guide rail. The number of casters is configured according to the length of the crossbeam and load requirements, typically with 2-4 casters on each side. The contact surface between the casters and the moving guide rail can be machined into a groove structure, forming a fitting fit with the guide rail, thereby enhancing operational stability. The casters are fixed to both sides of the moving crossbeam by adjustable mounting brackets, facilitating fine-tuning and maintenance replacement.

[0025] To address this issue, the technical solution incorporates a moving wheel structure, enabling the moving crossbeam to move smoothly along the guide rail, effectively resolving the jamming problem of the protective cover during crossbeam movement. The multi-wheel support design distributes the crossbeam load, preventing guide rail deformation caused by localized stress concentration and extending the equipment's service life. Specifically, during the centrifugal molding process of cement poles, this structure ensures the protective cover moves smoothly with the mold, promptly blocking splashed concrete slurry, while simultaneously reducing equipment operating energy consumption and maintenance frequency.

[0026] Furthermore, this application also proposes that the two sides of the protective cover be fixedly connected to the upper movable crossbeam via connecting frames.

[0027] Specifically, the connecting frame is fixed with angle steel arranged in a figure-eight shape. In practice, when concrete slurry splashes and impacts the inside of the protective cover, the connecting frame transmits the impact force to the support frame of the moving crossbeam. Through the cooperation of the moving wheels and guide rails, dynamic stress dispersion is achieved, thereby significantly improving the durability of the protective structure.

[0028] Furthermore, this application also proposes that the guiding collection assembly includes a plurality of adjacent guiding protrusions disposed inside the protective cover, with a guiding groove formed between adjacent guiding protrusions, and the bottom sides of the protective cover bent inward to form a collection groove.

[0029] The guide ridges can be made of rubber or plastic, with a triangular or trapezoidal cross-sectional shape, and the spacing between adjacent guide ridges is 5-10 cm. The depth of the guide groove is preferably 3-5 cm, and the width matches the spacing between the guide ridges. The bending angle of the collection groove is 90-120 degrees, and the groove depth is 8-12 cm.

[0030] This technical solution effectively collects cement slurry splashed during centrifugation by incorporating guide ribs and a collection trough inside the protective cover. The guide ribs direct the splashed material into the collection trough, preventing the cement slurry from scattering. The guide trough formed by adjacent guide ribs increases the collection area and improves collection efficiency. The collection trough formed by the bend at the bottom of the protective cover temporarily stores the collected cement slurry, facilitating subsequent cleaning. Thus, it solves the problem of cement slurry polluting the environment and also achieves material recycling. Compared with existing technologies, this solution has a simple structure, is easy to maintain, and has a significant collection effect.

[0031] Furthermore, this application also proposes that the two ends of the collection tank are provided with detachable inserts.

[0032] Specifically, the insert plates are installed at the ends of the collection tank via sliding or snap-fit ​​methods. This technical solution solves the problem of slurry leakage from both ends of the collection tank during centrifugation by installing detachable insert plates at both ends. When the guide ribs inside the protective cover guide the splashed slurry into the collection tank, the insert plates effectively prevent the slurry from flowing out axially. When cleaning is required, simply removing the insert plates removes the accumulated slurry from the tank, maintaining a clean working environment and enabling the recycling of cement materials. Compared with existing technologies, this structure is simple, reliable, and easy to maintain, significantly improving the practicality and economy of the protective components.

[0033] Furthermore, this application proposes that a movable guide rail be installed at the thicker end of the pole mold. The specific installation position of the movable guide rail is limited to the end region with the larger diameter of the pole mold, corresponding to the area where slurry splashing is most severe during the centrifugal molding of concrete. The movable guide rail can be fixed to the support frame by welding or bolting, and its length must cover the effective working area of ​​the thicker end of the pole mold. The cross-sectional shape of the guide rail can be I-shaped, channel-shaped, or rectangular, and the material is preferably wear-resistant alloy steel to withstand long-term sliding friction.

[0034] Specifically, by positioning the moving guide rail at the thicker end, the movement trajectory of the protective cover precisely covers the main area where mud splash occurs. As the moving beam moves along the guide rail, the protective cover completely shields the joint between the thicker end and the support rollers. Guide ribs in the guide collection assembly guide the splashed mud to the collection trough, while the insert plate at the end of the collection trough facilitates periodic cleaning of sediment. This arrangement matches the protective cover's coverage area with the distribution characteristics of mud splash, significantly improving collection efficiency. When it is necessary to hoist the pole mold, the moving beam can be moved along the moving guide rail to move the protective cover away from the pole mold, facilitating the operation of the pole mold.

[0035] Therefore, this technical solution solves the problem of incomplete collection of mud splash from the coarse end by optimizing the guide rail layout. Compared with existing technologies, its advantages are: the working trajectory of the protective cover matches the main spatial distribution of mud splash, avoiding blind spots in protection; the collection tank is located closer to the mud splash source, reducing material spillage during transportation; and the overall structure does not require additional power units, improving the protective effect simply by optimizing the mechanical layout.
