Description

Technical Field

[0001] The invention belongs to the technical field of concrete pole production, and in particular relates to a mold for producing and processing high-strength concrete poles. Background Art

[0002] Concrete poles are important supporting structures for power transmission, lighting and communication networks. Their development stems from the demand for alternatives to traditional wooden poles and steel poles. Early transmission lines generally used wooden poles, but they had defects such as easy decay, short lifespan and insufficient strength. Although steel poles are high in strength, they are expensive and prone to rust. In the early 20th century, with the maturity of reinforced concrete technology, centrifugal forming technology was introduced into pole manufacturing, giving birth to modern prestressed concrete poles. Its core technology lies in prestressing technology: by tensioning high-strength steel bars, the concrete is pre-stressed before bearing the load, significantly improving its bending and crack resistance. The production process adopts the centrifugal method - the concrete mixture is injected into a high-speed rotating steel mold. The centrifugal force makes the material dense and layered, forming a hollow ring section, which has the advantages of both lightweight and high strength.

[0003] The production molds of concrete poles are the core equipment in the manufacturing process, which directly affects product quality and production efficiency. The existing molds all adopt a patchwork design, which may lead to poor sealing at the joints and leakage during concrete pouring and centrifugation, affecting the density and strength of the poles, resulting in a decline in product quality and even waste. At the same time, the versatility of existing production molds is poor. Concrete poles of different specifications and models require different molds. The versatility and interchangeability of the molds are poor, which requires companies to equip a large number of different types of molds when producing different products, increasing production costs and management difficulties. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a mold for the production and processing of high-strength concrete poles.

[0005] The technical solution adopted to solve the above technical problems is: a mold for the production and processing of high-strength concrete poles, comprising a plurality of mold shell assemblies, wherein the plurality of mold shell assemblies are connected to each other, and the end of the mold shell assembly located on the outside away from the mutual connection is fixedly connected to a connecting cover by bolts, and sealing assemblies are respectively installed on the outside of the mutual connection of the plurality of mold shell assemblies and the connection between the mold shell assembly and the connecting cover; the inner side of the connecting cover is rotatably connected to the sealing cover, and a mold liner assembly is provided on the inner side of the mold shell assembly.

[0006] Furthermore, the mold shell assembly includes two symmetrically arranged half shells, the two half shells are connected to each other to form a cylindrical structure, and first connecting flanges are fixedly connected to both ends of the half shells.

[0007] Through the above technical solution, a modular splicing structure is realized. The mold consists of two symmetrical half shells, which are connected to each other to form a cylindrical structure. This design makes the mold very easy to disassemble and assemble. When the mold needs to be inspected, cleaned or parts need to be replaced, it is only necessary to separate the two half shells to quickly enter the mold for operation. This convenience greatly reduces the maintenance time and labor intensity of the mold. At the same time, the processing plant can splice multiple sections of mold shell components through the first connecting flange according to the length requirements of different poles, and can easily produce poles of different specifications. This flexibility enables the mold to adapt to the diverse needs of the market. Enterprises can quickly adjust the mold to produce different types of poles according to order requirements without having to redesign and manufacture the entire set of molds.

[0008] Furthermore, the connecting cover includes a second connecting flange, and a surface of the second connecting flange is provided with a plurality of second semi-hidden connecting holes.

[0009] Through the above technical solution, the connecting cover seals the side opening of the mold shell assembly, avoiding leakage of internal mortar during subsequent high-speed rotation of the mold, ensuring the molding effect of the concrete pole. At the same time, the connection setting of the second connecting flange can be disassembled and cleaned in a very short time, and then reinstalled and put into production, greatly improving production efficiency.

[0010] Furthermore, the sealing assembly includes two semicircular concave sleeves, and the inner sides of the semicircular concave sleeves are respectively slidably engaged with the second connecting flange and the first connecting flange.

[0011] Through the above technical solution, the sealing assembly further reinforces and seals the connection between the multi-section mold shell assembly and the connecting cover. At the same time, this tight fit can effectively prevent the concrete slurry from leaking from the flange connection, ensuring that the concrete inside the mold will not overflow during the pouring process, thereby improving the quality and surface finish of the pole. The semicircular concave sleeve forms a complete circular structure, and the sliding engagement between its inner side and the flange enhances the overall structural stability of the mold, helps to resist centrifugal force and concrete pressure, and reduces the risk of deformation of the mold during use, thereby extending the service life of the mold. Finally, the sliding engagement design makes the installation and disassembly of the semicircular concave sleeve relatively simple, which is convenient for inspecting, cleaning or replacing the sealing assembly, reducing the maintenance difficulty and cost of the mold and improving production efficiency. The sealing assembly can directly contact the roller on the high-speed centrifuge, which can effectively prevent the mold from shaking or offsetting during high-speed rotation. This stable contact method ensures that the mold remains balanced throughout the centrifugal process, reduces deformation or damage caused by vibration or irregular movement, and thus improves the service life of the mold.

[0012] Furthermore, the mold liner assembly includes a C-shaped shaping plate, and the C-shaped shaping plate is fixedly fitted to the inner side of the half shell.

[0013] Through the above technical solution, the C-type shaping can be independent of the half-shell, so that the processing plant can easily produce poles of different specifications. This replaceable mold liner component also meets the diverse needs of the market. Enterprises can quickly change the mold to produce different types of poles according to order requirements without having to redesign and manufacture the entire set of molds.

[0014] Furthermore, a plurality of first semi-hidden connecting holes are provided on the surface of the first connecting flange, wherein one of the first connecting flanges is provided with a first connecting ridge away from the surface of the half shell, and another of the first connecting flanges is provided with a first connecting groove away from the surface of the half shell, and the first connecting ridges located on different mold shell components are slidably engaged with the first connecting grooves.

[0015] Through the above technical solution, through the engagement operation of the ridges and grooves, the two mold shell components can be quickly and accurately aligned and positioned when connected, effectively improving the efficiency of mold assembly, reducing the time and errors of manual operation, and further strengthening the sealing effect between the multi-section mold shell components, greatly avoiding the leakage of concrete mortar, improving the sealing of the mold, and ensuring the quality of the pole. When the mold is subjected to external forces such as centrifugal force and concrete pressure, this engagement structure can evenly distribute stress, reduce local stress concentration, reduce the risk of mold deformation, and extend the service life of the mold.

[0016] Furthermore, the outer surface of the half shell is fixedly connected with a reinforcing rib, and the reinforcing rib is a criss-cross structure. The two sides of the reinforcing rib are respectively fixedly connected to the first connecting flanges at both ends. The inner surface of one end of the reinforcing rib is provided with a plurality of sealing grooves, and the inner surface of the other end of the reinforcing rib is provided with a plurality of sealing ridges. The plurality of sealing grooves and sealing ridges are arranged in an array, and the sealing ridges located at different half shells are slidingly engaged with the sealing grooves. The inner sides of both ends of the reinforcing rib are provided with a plurality of square grooves, and the plurality of square grooves are evenly arranged in an array along the surface of the reinforcing rib. The inner side of the square groove is slidingly fixedly connected with an insert plate. The two ends of the reinforcing rib are also provided with shell connecting holes, and the shell connecting hole is located on one side of the insert plate. The two sections of the half shells are fixedly connected by a bolt structure that passes through the shell connecting hole. Lock grooves are provided on the side of the first connecting flange at both ends of the reinforcing rib.

[0017] Through the above technical solution, the reinforcing ribs adopt a crisscross structure and are connected to the flange to form an integral force frame. This layout can evenly disperse stress, improve the bending and torsional strength of the half shells, and prevent the mold from deforming under centrifugal and concrete pressure. Several sealing grooves and sealing ridges are arranged in an array and are respectively provided on the inner surfaces of both ends of the reinforcing ribs. When the two half shells are docked, the sealing ridges slide and engage with the sealing grooves to form multiple sealing lines of defense, effectively preventing concrete slurry from leaking from the connection. The plug-in plate slides and is fixed in the square groove and can be quickly inserted or pulled out as needed, which facilitates the inspection, cleaning or replacement of the sealing components. When the concrete pole is formed, when the mold needs to be removed, since the three sides of the plug-in plate are located between the two half shells, when the plug-in plate is knocked, the three sides of the plug-in plate are located between the two half shells, forming a lever effect. By knocking one end of the plug-in plate, the half shell can be easily pried using the lever principle to loosen the connection between the two half shells, thereby facilitating the rapid removal of the mold.

[0018] Furthermore, the inner side of the semi-shell curved surface is fixedly fitted with the mold liner assembly, a second connecting groove is provided in the middle of the inner side of the semi-shell curved surface, the second connecting groove is engaged and fixed with the mold liner assembly, and square notches are provided at the four corners of the inner side of the semi-shell curved surface, the square notches are slidably connected with the mold liner assembly.

[0019] Through the above technical solution, the setting of the second connecting groove and the square notch facilitates the engagement and fixation of the inner liner assembly, prevents the position of the inner liner assembly from shifting during subsequent high-speed centrifugal operations, and ensures the stability of the connection between the inner liner assembly and the semi-shell.

[0020] Furthermore, a plurality of arc grooves are respectively provided on both sides of the semicircular concave sleeve, a fixed groove is provided on one side of several of the arc grooves, a notch is provided in the middle of the semicircular concave sleeve, the inner sides of the notch are respectively slidably engaged with the reinforcing ribs, the inner side of the semicircular concave sleeve is slidably connected with an arc-shaped U-plate, a locking strip is provided in the middle of the arc-shaped U-plate, the locking strip is slidably engaged with the locking slot, a plurality of pull handles are fixedly connected on both sides of the arc-shaped U-plate, the pull handle is slidably connected with the arc groove, the middle part of the pull handle is slidably connected with a plug-in table, one end of the plug-in table is slidably engaged with the fixed groove, the middle part of the plug-in table is rotatably connected with a cross knob, and the cross knob is threadably rotatably connected to the pull handle.

[0021] Through the above technical solution, when the two semicircular concave sleeves are merged between the two flanges, the processing personnel pulls the handle, and the handle moves along the arc groove toward one end of the fixed groove, so that one end of the arc-shaped U-plate rotates and extends out of the semicircular concave sleeve, and the other end of the arc-shaped U-plate penetrates into the semicircular concave sleeve. The two different semicircular concave sleeves engage with each other to form a whole. During this process, the locking strip in the middle of the arc-shaped U-plate slides and engages with the locking grooves at both ends of the reinforcement rib. Finally, the cross knob is rotated and the insert is pressed down. The bottom end of the insert engages with the fixed groove to fix the arc-shaped U-plate and form a stable locking mechanism. This design ensures that the semicircular concave sleeves will not move relative to each other after being merged, thereby improving the stability of the connection. Therefore, the design of the sealing component allows it to maintain good performance after multiple installation and disassembly, reducing maintenance costs.

[0022] Furthermore, a third connecting ridge is fixedly connected to the middle of the C-shaped forming plate, and the third connecting ridge is fixedly engaged with the second connecting groove. A number of positioning posts are fixedly connected to both sides of the C-shaped forming plate, and the positioning posts are slidably connected with the square notch. One side of the through end of the positioning post is rotatably connected with a T-shaped clip. A second spring is provided on the side of the T-shaped clip close to the rotating end. One side of the T-shaped clip is engaged with the square notch, and the end of the T-shaped clip away from the engagement is slidably connected with a slide bar. A sealing plate is rotatably connected to the middle of the slide bar, and the sealing plate is rotatably connected to the positioning post at one end away from the slide bar.

[0023] Through the above technical solution, the third connecting protrusion in the middle of the C-shaped forming plate is fixedly engaged with the second connecting groove in the middle of the inner side of the semi-shell curved surface, and the positioning columns on both sides of the C-shaped forming plate are slidably connected with the square notches at the four corners of the inner side of the semi-shell curved surface, which further increases the number of support points and connection points, making the connection between the C-shaped forming plate and the semi-shell more firm, improving the overall structural strength of the mold, and helping to resist centrifugal force and concrete pressure. When the positioning column and the square notch are slidably connected, the engagement of the T-shaped strip and the square notch and the elastic force of the second spring can quickly lock or release the C-shaped forming plate, which is convenient for installation and disassembly. The operator can complete the fixing or release of the C-shaped forming plate through simple operations, reducing the difficulty of operation.

[0024] Furthermore, the second connecting flange and the first connecting flange are fixedly connected by a bolt structure that passes through the second semi-hidden connecting hole and the shell connecting hole. Positioning bosses are provided on both sides of the surface of one end of the second connecting flange, and a limiting groove is provided on the inner side of the second connecting flange. A second connecting ridge is provided on the surface of one end of the second connecting flange away from the second semi-hidden connecting hole, and the second connecting ridge is slidably engaged with the first connecting groove.

[0025] Through the above technical solution, the second connecting flange and the first connecting flange are fixedly connected by a bolt structure that passes through the second semi-hidden connecting hole and the shell connecting hole. Through multiple bolt connections, multi-point fixation can be achieved, which further enhances the reliability of the connection and reduces the risk of loosening or damage of the connection due to local stress concentration. This bolt connection method provides a strong and reliable connection that can withstand large forces and torques, ensuring the stability of the connection. Through the engagement of the second connecting ridge and the first connecting groove, an effective sealing structure is formed. This engagement structure can effectively prevent concrete slurry from leaking from the flange connection, thereby improving the sealing performance of the mold.

[0026] Furthermore, a handle is fixedly connected to the surface of one side of the sealing cover, a rubber ring is provided on the circumferential surface of the sealing cover, and a clamping column is symmetrically passed through the circumferential surface of the sealing cover for sliding connection, the through ends of the two clamping columns are slidingly engaged with the limiting grooves, and the two ends of the clamping columns located inside are rotatably connected to a pull plate, and a T-shaped column is rotatably connected between the two pull plates, and a first spring is provided at one end of the T-shaped column, and the first spring is fixedly connected to the inside of the handle at one end away from the T-shaped column, and the T-shaped column is slidably passed through the surface of the handle at one end away from the first spring, and the through end of the T-shaped column is fixedly connected to the pressure plate.

[0027] Through the above technical solution, the sealing cover can be fixed on the inner side of the connecting flange by sliding engagement between the through end of the clamping column and the limiting groove. The setting of the rubber ring forms a reliable elastic sealing line of defense, which effectively prevents the concrete slurry from leaking from the connection and improves the sealing performance of the mold. When the centrifugal operation is completed, the pressure plate is pressed, and the clamping column is pulled back through the linkage structure of the T-column and the pull plate. At this time, the sealing cover can be pulled out by pulling the handle to facilitate the outflow of excess liquid.

[0028] The beneficial effects of the present invention are as follows:

A third connecting ridge 502 is fixedly connected to the middle of the C-shaped shaping plate 501, and the third connecting ridge 502 is fixedly engaged with the second connecting groove 111. A plurality of positioning columns 503 are fixedly connected to both sides of the C-shaped shaping plate 501. The positioning columns 503 are connected to the square notch 113 through a sliding connection, which further increases the number of support points and connection points, making the connection between the C-shaped shaping plate 501 and the semi-shell 101 more secure, thereby improving the structural strength of the mold as a whole and helping to resist centrifugal force and concrete. The pressure of the positioning column 503 is rotatably connected to a T-shaped clip 504 on one side of the through end, and a second spring 507 is provided on the side of the T-shaped clip 504 close to the rotating end. One side of the T-shaped clip 504 engages with the square notch 113, and the end of the T-shaped clip 504 away from the engagement is slidably connected to a slide bar 505, and the middle of the slide bar 505 is rotatably connected to a sealing plate 506, and the sealing plate 506 is rotatably connected to the positioning column 503 at one end away from the slide bar 505, which can quickly lock or release the C-shaped shaping plate 501, making it easy to install and disassemble. The operator can complete the fixing or release of the C-shaped shaping plate 501 through simple operations, reducing the difficulty of operation.

[0056] The working principle of this embodiment is as follows:

[0057] In actual operation, when it is necessary to produce and process concrete poles, first, according to the required length of the pole, an appropriate number of mold shell components 1 are selected for splicing. The operator slides the first connecting protrusion 104 of the mold shell component 1 into engagement with the first connecting groove 110 of the adjacent mold shell component 1 to ensure that each mold shell component 1 is accurately aligned. Subsequently, the two half-shells 101 and the adjacent mold shell components 1 are firmly fixed together by passing the bolt structure through the shell connection hole 107 to form a complete mold shell. During the splicing process, the sealing protrusion 114 on the reinforcing rib 103 slides into engagement with the sealing groove 112, further enhancing the sealing performance of the mold shell.

[0058] Next, the C-shaped shaping plate 501 of the mold liner assembly 5 is fixedly fitted to the inner side of the half shell 101, the third connecting protrusion 502 is fixedly engaged with the second connecting groove 111, and at the same time, the positioning column 503 is slidably connected with the square notch 113, and the T-shaped clip 504 is tightly engaged with the square notch 113 under the action of the second spring 507, ensuring that the mold liner assembly 5 is stably installed in the mold shell.

[0059] Then, install the sealing assembly 2. The operator slides the inner side of the semicircular concave sleeve 201 into engagement with the second connecting flange 301 and the first connecting flange 102 respectively. The locking bar 209 of the arc-shaped U-plate 202 slides into engagement with the locking groove 106. By turning the cross knob 208, the insert 207 slides into engagement with the fixing groove 206, thereby fixing the semicircular concave sleeve 201 and the arc-shaped U-plate 202 in place, forming a reliable sealing line of defense.

[0060] At the top of the mold, the operator fixes the second connecting flange 301 of the connecting cover 3 with the first connecting flange 102 of the mold shell assembly 1 through a bolt structure. At the same time, the second connecting protrusion 305 slides and engages with the first connecting groove 110, further enhancing the stability and sealing performance of the connection.

[0061] Finally, install the sealing cover 4. The operator fits the rubber ring 403 of the sealing cover 4 tightly with the inner side of the connecting flange, and presses the pressure plate 402 to make the linkage structure of the T-shaped column 406 and the pull plate 405 pull the clamping column 404 back. Then, the through end of the clamping column 404 of the sealing cover 4 is slidably engaged with the limiting groove 304. Under the action of the first spring 407, the clamping column 404 is firmly fixed in the limiting groove 304, thereby completing the installation of the sealing cover 4.

[0062] At this point, the mold is ready for the production and processing of concrete poles. By injecting concrete slurry into the mold and performing a centrifugal operation, a high-strength, uniform-quality concrete pole can be produced. After completing the centrifugal operation, the operator can press the pressing plate 402, and pull the clamping column 404 back through the linkage structure of the T-column 406 and the pull plate 405, and then pull out the sealing cover 4 to facilitate the outflow of excess liquid. Finally, by removing the bolt structure, the mold shell assembly 1 and the mold liner assembly 5 can be easily disassembled for the next production and processing.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
