[0038] The following is a more detailed description of a concrete tower mold according to the present invention, with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0039] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0040] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a concrete tower mold, including an inner mold 1, an outer mold 2, an end mold 3, and a bottom mold 4.

[0041] Specifically, both the inner mold 1 and the outer mold 2 are mounted on the bottom mold 4; the outer mold 2 is configured to form a cavity 5 with variable wall thickness between itself and the inner mold 1 by selecting and combining different segments; the end mold 3 connects the ends of the inner mold 1 and the outer mold 2. This embodiment, by selecting and combining different segments of the outer mold 2, can flexibly form cavities 5 with different wall thicknesses, thereby adapting to the production needs of concrete tower cylinders 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, the plurality of first segments 21 are connected in sequence to form a main frame; the plurality of second segments 22 are connected to the two sides of the main frame respectively; the side of the second segment 22 away from the main frame and the two sides of the inner mold 1 are provided with a plurality of first connecting holes, and the end mold 3 is provided with second connecting holes matched with the first connecting holes; the outer mold 2, the inner mold 1 and the end mold 3 are assembled by connecting pieces passing through the first connecting holes and the second connecting holes. The connecting piece can be a bolt. The first connecting hole and the second connecting hole can be arranged in multiple rows, and the second segment 22 used for different cavity 5 thicknesses needs to be staggered, so that the first connecting hole and the second connecting hole on the second segment 22 are on the same straight line with the end mold 3 after the concrete tower tube mold of the cavity 5 with different wall thicknesses is installed in place, thereby facilitating installation.

[0044] By using a plurality of first segments 21 to form a main frame and a second segment 22, the embodiment realizes the modular design of the mold, which is convenient for quickly adjusting the mold structure according to different wall thickness requirements. By designing the multi-row arrangement of the first connecting hole and the second connecting hole and the staggered arrangement of the second segment 22, it is ensured that the molds of different wall thickness cavities 5 can be accurately aligned during assembly, thereby improving the accuracy of assembly and the stability of the mold.

[0045] In the embodiment, the main frame and the end mold 3 have a mounting space. Specifically, the second segment 22 is located in the mounting space, and the width dimension of the second segment 22 is equal to the width dimension of the mounting space, and the length dimension of the second segment 22 is equal to the length dimension of the second segment 22.

[0046] In the embodiment, when the thickness of the cavity 5 increases (for example, the increase process changes in steps), the arc length of the outer mold 2 as a whole also increases, while the length dimension of the first segment 21 is fixed 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, as shown in Figure 4 The number of first segments 21 is 4, and the 4 first segments 21 are connected in sequence to form a main frame. The number of second segments 22 is 2, and the two sides of the main frame can be detachably connected. The detachable connection can be bolt connection. When it is necessary to expand the predetermined size of the cavity 5, the main frame moves away from the inner mold 1, and the two sides of the main frame after moving away from the inner mold 1 have a first interval with the end mold 3 at this time. Therefore, a second segment 22 with the same width dimension as the first interval needs to be filled into the first interval, so that the two sides of the second segment 22 are detachably connected with the end mold 3 and the first segment 21 respectively (for example, bolt connection can be used, which is convenient for later disassembly and replacement of the second segment 22). Combined with Figure 4 and Figure 5As shown, Figure 5 For the case that the width dimension of the second segment 22 is larger than Figure 4 For the case that the width dimension of the second segment 22 is larger than

[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 base mold 4 to form an arc-shaped structure. The arc-shaped sheet structure allows the inner mold 1 and the outer mold 2 to more evenly disperse pressure when stressed, thereby enhancing the overall structural strength and durability of the mold. The arc-shaped structure better conforms to the design shape of the concrete tower drum, ensuring uniform distribution and pressure transmission of the concrete during the molding process, thereby improving the geometric precision 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 near one side of the base mold 4; the base mold 4 is provided with a plurality of second mounting holes 41 that cooperate with the first mounting holes; the inner mold 1 and the outer mold 2 are installed on the base mold 4 by screwing the first mounting holes and the second mounting holes 41 with mounting members. By providing a plurality of mounting holes on the inner mold 1 and the outer mold 2 near the base mold 4 and cooperating with the mounting holes on the base mold 4, the overall stability of the mold is enhanced, ensuring that the cavity 5 maintains an accurate shape during concrete pouring. The use of threaded connections allows for quick and secure installation of the inner mold 1 and the outer mold 2, improving the assembly efficiency of the mold and reducing the production preparation time.

[0050] In an embodiment, as shown, Figure 6 The base mold 4 includes a plurality of connecting panels 42, a boss assembly 43, and a fixed plate 44.

[0051] Specifically, the boss assembly 43 is arranged between the plurality of connecting panels 42 and forms an arc-shaped structure with the connecting panels 42; the fixed plate 44 is located at both ends of the arc-shaped structure and is connected to the connecting panels 42; the connecting panels 42 are provided with the second mounting holes 41. By using the arc-shaped structure composed of the connecting panels 42, the boss assembly 43, and the fixed plate 44, the overall stability of the base mold 4 is enhanced, ensuring the firmness and reliability of the mold during concrete pouring.

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

[0053] Specifically, the plurality of connecting panels 42 include a first connecting panel 421 and a second connecting panel 422 arranged in parallel (wherein the plurality of connecting panels 42 can be integrally formed, or the plurality of connecting panels 42 form a panel structure including the first connecting panel 421 and the second connecting panel 422 arranged in parallel); one side of the fixed boss 431 is connected to the first connecting panel 421; and one side of the movable boss 432 away from the fixed boss 431 is connected to the second connecting panel 422. The arrangement of the movable boss 432 allows the boss assembly 43 to be adjusted within a certain range to adapt to the production requirements of concrete tower drums of different diameters or wall thicknesses, thereby improving the adaptability and flexibility of the mold. Through the connection of the movable boss 432 and the second connecting 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 connecting panel 422, for example, by punching holes on the opposite side walls of the movable boss 432 and the second connecting panel 422, and then using bolts or the like for threaded connection. The fixed connection of the fixed boss 431 and the first connecting panel 421 provides a stable support foundation, while the adjustability of the movable boss 432 increases the flexibility of the overall structure, optimizing the structural design of the mold.

[0055] As known to those skilled in the art, the detachable connection in the present embodiment can also use other embodiments in addition to the bolts described in the present embodiment.

[0056] In a specific example, the inner mold 1 is installed on the first connecting panel 421, and the bottom is attached to the side of the fixed boss 431 facing the first connecting panel 421; the outer mold 2 is installed on the second connecting panel 422, and if the thickness of the cavity 5 needs to be reduced, the outer mold 2 moves towards the inner mold 1, and the movable boss 432 between the fixed boss 431 and the second connecting panel 422 is removed. By adding the movable boss 432 between the fixed boss 431 and the second connecting panel 422, the thickness of the cavity 5 can be flexibly adjusted to adapt to different production requirements, 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, reducing local stress concentration, and improving 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 changed, reducing the mold adjustment time and thereby improving production efficiency.

[0057] In an embodiment, as Figures 7-8As shown, the top of the inner mold 1 is connected with the top of the outer mold 2 through a pull rod assembly 6; the pull rod assembly 6 comprises a first mounting seat, a second mounting seat and a traction screw 63.

Through the arrangement of the pull rod assembly 6, the distance between the inner mold 1 and the outer mold 2 can be accurately controlled, so as to accurately control the size of the cavity 5 and ensure the quality and precision of the concrete tower.

[0059] Preferably, the traction screw 63 can be a telescopic screw, which is convenient for size change according to cavities 5 with different wall thicknesses and reduces the frequency of replacing molds.

[0061] Specifically, the mounting plate 61 is mounted on the device 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 top of the outer mold 2 and the top of the inner mold 1 are both provided with a plurality of device holes; the device plate 62 is provided with a plurality of arc-shaped grooves 620 matched with the device holes, and a plurality of the arc-shaped grooves 620 in the same device plate 62 are located on the same circumference, and the device plate 62 can be angularly finely adjusted along the center of the circumference; the device plate 62 is mounted on the top of the outer mold 2 or the inner mold 1 through device pieces passing through the arc-shaped grooves 620 and the device holes. Through the cooperation of the arc-shaped grooves 620 on the device plate 62 and the device holes on the top of the outer mold 2 or the inner mold 1, accurate alignment and fine adjustment are realized, and accurate cooperation and installation between mold assemblies are ensured. The design of the first mounting seat and the second mounting seat provides stable fixing points, so that the traction screw 63 can be firmly mounted, and the stability of the entire mold structure is enhanced. The device plate 62 can be angularly finely adjusted, so that the device can adapt to installation requirements of different angles and improve the installation flexibility of the device.
