[0038] A concrete tower drum mold of the present invention will be described in more detail below in conjunction with the accompanying drawings, wherein preferred embodiments of the present invention are shown. It should be understood that those skilled in the art may modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation of the present invention.

[0039] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and are not in exact proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0040] like Figure 1-3 As shown, an embodiment of the present invention provides a concrete tower mold, including an inner mold 1, an outer mold 2, an end mold 3 and a bottom mold 4.

[0041] Specifically, the inner mold 1 and the outer mold 2 are both mounted on the bottom mold 4; the outer mold 2 is configured to form a cavity 5 with a variable wall thickness between the inner mold 1 by selecting and combining different segments; the end mold 3 connects the inner mold 1 and the end of the outer mold 2. This embodiment can flexibly form a cavity 5 with different wall thicknesses by selecting and combining different segments of the outer mold 2, thereby meeting the production requirements of concrete towers of different specifications and improving the versatility and economy of the mold.

[0042] In one embodiment, the outer mold 2 includes a plurality of first segments 21 and a plurality of second segments 22 .

[0043] Specifically, a plurality of the first segments 21 are connected in sequence to form a main frame; a plurality of the second segments 22 are connected to both sides of the main frame respectively; a plurality of first connection holes are provided on the side of the second segment 22 away from the main frame and on both sides of the inner mold 1, and a second connection hole matching with the first connection hole is provided on the end mold 3; the outer mold 2, the inner mold 1 and the end mold 3 are assembled by connecting members passing through the first connection holes and the second connection holes. The connecting members may be bolts. The first connection holes and the second connection holes may be arranged in multiple rows, and the second segments 22 for different thicknesses of cavities 5 need to be offset, so that after the concrete tower molds of cavities 5 with different wall thicknesses are installed in place, the first connection holes and the second connection holes on the second segment 22 are in the same straight line with the end mold 3, thereby facilitating installation.

[0044] By using a plurality of first segments 21 to form a main frame and a second segment 22, this embodiment realizes a modular design of the mold, and facilitates rapid adjustment of the mold structure according to different wall thickness requirements. By designing a multi-row arrangement of the first connection holes and the second connection holes and the misalignment of the second segments 22, it is ensured that molds of cavities 5 with different wall thicknesses can be accurately aligned during assembly, thereby improving the accuracy of assembly and the stability of the mold.

[0045] In this embodiment, there is an installation space between the main frame and the end mold 3. Specifically, the second segment 22 is located in the installation space, and the width dimension of the second segment 22 is equal to the width dimension of the installation space, and the length dimension of the second segment 22 is equal to the length dimension of the second segment 22.

[0046] In this embodiment, when the thickness of the cavity 5 increases (for example, the increase process is a step-like change), the arc length of the outer mold 2 as a whole also increases, while the length of the first segment 21 remains unchanged and the size is set according to the actual situation. The size of the second segment 22 can be set according to the size required in addition to the size of the main frame composed of the first segment 21.

[0047] For example, Figure 4 As shown, the number of first slices 21 is 4, and the four first slices 21 are connected in sequence to form a main frame. The number of second slices 22 is 2, which are detachably connected to both sides of the main frame. The detachable connection can be a bolt connection. When the cavity 5 of a predetermined size needs to be expanded, the main frame moves in the direction away from the inner mold 1, and the two sides of the main frame away from the inner mold 1 now have a first interval with the end mold 3. Therefore, it is necessary to use a second slice 22 with the same width as the first interval to fill the first interval, so that the two sides of the second slice 22 are detachably connected to the end mold 3 and the first slice 21 respectively (for example, bolts can be used to facilitate the later disassembly and replacement of the second slice 22). Combined with Figure 4 and Figure 5As shown, Figure 5 The width of the second slice 22 is compared to Figure 4 When the size of the second segment 22 increases, as the required thickness of the cavity 5 increases, the corresponding size of the width of the second segment 22 is selected, so that the cavity 5 of the required thickness can be formed between the outer mold 2 as a whole, the inner mold 1 and the end mold 3. Therefore, the thickness of the cavity 5 can be adjusted by adjusting the position and perimeter of the outer mold 2.

[0048] Preferably, the inner mold 1 and the outer mold 2 are both arc-shaped sheet structures; the inner mold 1 and the outer mold 2 are both distributed along the upper surface of the bottom mold 4 to form an arc-shaped structure. The arc-shaped sheet structure allows the inner mold 1 and the outer mold 2 to disperse the pressure more evenly when subjected to force, thereby enhancing the overall structural strength and durability of the mold. The arc-shaped structure can better fit the design shape of the concrete tower, ensuring the uniform distribution and pressure transmission of concrete during the molding process, thereby improving the geometric accuracy and surface quality of the finished product.

[0049] In a specific embodiment, the inner mold 1 and the outer mold 2 are both provided with a plurality of first mounting holes on one side close to the bottom mold 4; the bottom mold 4 is provided with a plurality of second mounting holes 41 that match the first mounting holes; the inner mold 1 and the outer mold 2 are installed on the bottom mold 4 by threading the first mounting holes and the second mounting holes 41 with a mounting member. By providing a plurality of mounting holes on one side of the inner mold 1 and the outer mold 2 close to the bottom mold 4 and matching with the mounting holes on the bottom mold 4, the overall stability of the mold is enhanced, ensuring that the cavity 5 maintains a precise shape when pouring concrete. The use of threaded connection allows the inner mold 1 and the outer mold 2 to be installed quickly and firmly, improves the assembly efficiency of the mold, and reduces the production preparation time.

[0050] In one embodiment, if Figure 6 As shown, the bottom mold 4 includes a plurality of connecting panels 42 , a boss assembly 43 and a fixing plate 44 .

[0051] Specifically, the boss assembly 43 is arranged between the plurality of connection panels 42 and forms an arc structure with the connection panels 42; the fixing plates 44 are located at both ends of the arc structure and connected to the connection panels 42; the connection panels 42 are provided with the second mounting holes 41. By using the arc structure formed by the connection panels 42, the boss assembly 43 and the fixing plates 44, the overall stability of the bottom mold 4 is enhanced, ensuring the firmness and reliability of the mold during the concrete pouring process.

[0052] In this embodiment, the boss assembly 43 includes a fixed boss 431 and a movable boss 432 which are arranged in parallel.

[0053] Specifically, the plurality of connection panels 42 include a first connection panel 421 and a second connection panel 422 arranged in parallel (wherein the plurality of connection panels 42 may be integrally formed, or the plurality of connection panels 42 may form a panel structure, wherein the panel structure includes a first connection panel 421 and a second connection panel 422 arranged in parallel); one side of the fixed boss 431 is connected to the first connection panel 421; and the side of the movable boss 432 away from the fixed boss 431 is connected to the second connection panel 422. The setting of the movable boss 432 allows the boss assembly 43 to be adjusted within a certain range to meet the production requirements of concrete towers with different diameters or wall thicknesses, thereby improving the adaptability and flexibility of the mold. Through the connection between the movable boss 432 and the second connection panel 422, the position of the boss assembly 43 can be quickly adjusted to match different mold settings, reducing the adjustment time and labor intensity in production.

[0054] Preferably, the movable boss 432 is detachably connected to the second connection panel 422, for example, by drilling holes on the side walls opposite to the movable boss 432 and the second connection panel 422, and then threading them with bolts, etc. The fixed connection between the fixed boss 431 and the first connection panel 421 provides a stable support foundation, while the adjustability of the movable boss 432 increases the flexibility of the overall structure and optimizes the structural design of the mold.

[0055] Those skilled in the art may appreciate that the detachable connection in this embodiment may also adopt other embodiments besides the bolts described in this embodiment.

[0056] In a specific example, the inner mold 1 is mounted on the first connection panel 421, and the bottom is in contact with the side of the fixed boss 431 facing the first connection panel 421; the outer mold 2 is mounted on the second connection panel 422. If the thickness of the cavity 5 needs to be reduced, the outer mold 2 moves toward the inner mold 1, and the movable boss 432 between the fixed boss 431 and the second connection panel 422 can be removed. By adding the movable boss 432 between the fixed boss 431 and the second connection panel 422, the thickness of the cavity 5 can be flexibly adjusted to meet different production requirements, thereby improving the adaptability and flexibility of the mold. In addition, by adding the movable boss 432, the installation contact surface of the outer mold 2 can be increased, thereby helping to disperse the force, reduce local stress concentration, and improve the durability and service life of the mold. By quickly adjusting the position of the movable boss 432, the thickness of the cavity 5 can be quickly assisted to change, reducing the time for mold adjustment, thereby improving production efficiency.

[0057] In one embodiment, if Figure 7-Figure 8As shown, the top of the inner mold 1 is connected to the top of the outer mold 2 via a tie rod assembly 6 ; the tie rod assembly 6 includes a first mounting seat, a second mounting seat and a traction screw 63 .

[0058] Specifically, the first mounting seat is mounted on the top of the inner mold 1; the second mounting seat is mounted on the top of the outer mold 2; the traction screw 63 is rotatably mounted on the second mounting seat through the mounting shaft; the end of the traction screw 63 away from the mounting shaft is movably mounted inside the first mounting seat, and the end of the traction screw 63 close to the first mounting seat is threadedly connected with a fixing nut 64; the first mounting seat is located between the fixing nut 64 and the second mounting seat. By setting the tie rod assembly 6, the distance between the inner mold 1 and the outer mold 2 can be accurately controlled, thereby accurately controlling the size of the cavity 5 and ensuring the quality and accuracy of the concrete tower.

[0059] Preferably, the traction screw 63 can be a telescopic screw, which is convenient for changing the size of the cavity 5 according to different wall thicknesses and reducing the frequency of mold replacement.

[0060] In this embodiment, both the first mounting seat and the second mounting seat include a mounting plate 61 and a device plate 62 .

[0061] Specifically, the mounting plate 61 is mounted on the mounting plate 62; one end of the traction screw 63 is rotatably mounted on the mounting plate 61 in the second mounting seat, and the other end is movably mounted in the mounting plate 61 of the first mounting seat; the tops of the outer mold 2 and the inner mold 1 are both provided with a plurality of mounting holes; the mounting plate 62 is provided with a plurality of arc grooves 620 that match the mounting holes, and the plurality of arc grooves 620 located in the same mounting plate 62 are located on the same circumference, and the mounting plate 62 can be fine-tuned along the center of the circumference; the mounting plate 62 is mounted on the top of the outer mold 2 or the inner mold 1 through the mounting parts passing through the arc grooves 620 and the mounting holes. Accurate alignment and fine-tuning are achieved through the coordination of the arc grooves 620 on the mounting plate 62 and the mounting holes on the top of the outer mold 2 or the inner mold 1, ensuring accurate coordination and installation between mold components. The design of the first mounting seat and the second mounting seat provides a stable fixing point, so that the traction screw 63 can be firmly installed, thereby enhancing the stability of the entire mold structure. The device plate 62 can be finely adjusted in angle, so that the device can adapt to installation requirements at different angles, thereby improving the installation flexibility of the device.

[0062] In one embodiment, a supporting device 7 is connected to a side of the inner mold 1 away from the outer mold 2 to improve overall stability.

[0063] In this embodiment, there are multiple end molds 3. Specifically, the multiple end molds 3 are respectively located at two ends of the outer mold 2, and one end of the outer mold 2 and one end of the inner mold 1 are connected to the same end mold 3.

[0064] Preferably, the end mold 3 can be set according to the thickest size actually required.

[0065] In this embodiment, the distance between the outer mold 2 and the inner mold 1 is adjusted, and the arc length (ie, circumference) of the entire outer mold 2 is adjusted by selecting second segments 22 of different widths, thereby achieving a cavity 5 with different wall thicknesses.

[0066] In summary, the concrete tower mold proposed by the present invention has the following advantages:
