[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment: This embodiment provides a wind turbine tower section forming mold, see Figure 1 - Fig.14 Specifically, it includes an outer template 1 and an inner template 2, the inner template 2 is coaxially arranged on the inner side of the outer template 1, a molding cavity is formed between the outer template 1 and the inner template 2, the outer template 1 is composed of a plurality of first arc plates 101 arranged around, a first vertically arranged rotating shaft 102 is fixed on the side of the first arc plate 101 away from the center of the outer template 1, the first arc plate 101 rotates around the first rotating shaft 102, and the rotation track of the first arc plate 101 will not invade the space range of the molding cavity, the inner template 2 is composed of a plurality of second arc plates 201 and a support plate 202 arranged around, the support plate 202 is clamped between two adjacent second arc plates 201, and the second arc plates A second vertically arranged shaft 203 is fixedly installed on one side of 201 close to the center of the inner template 2. The second arc plate 201 rotates around the second shaft 203. The rotation trajectory of the second arc plate 201 will not invade the space range of the molding cavity. A plurality of hydraulic push rods 204 are arranged around the inner side of the inner template 2. The support plate 202 is fixedly connected to the telescopic end of the hydraulic push rod 204. A bottom plate 3 is arranged at the bottom of the outer template 1 and the inner template 2, and the bottom plate 3 is composed of a plurality of surrounding fan-shaped plates 301. The fan-shaped plate 301 is provided with a first socket 302 corresponding to the first shaft 102 and a second socket 303 corresponding to the support plate 202.

[0021] During the use of the forming mold, a plurality of first curved plates 101 are arranged around and assembled to form an outer template 1 with a stable structure, and a plurality of second curved plates 201 and a support plate 202 are arranged around and assembled to form an inner template 2 with a stable structure. Since the forming cavity is located outside the inner template 2, when concrete is poured into the forming cavity, a force is applied from the outside to the second curved plates 201 and the support plates 202 to move toward the center of the inner template 2. Since the support plate 202 is kept stable and cannot move under the support of the hydraulic push rod 204, the second curved plate 201 is pressed against the second curved plate 201 by means of the fitting position of the support plate 202 and the second curved plate 201. 1, so that the second curved plate 201 is also unable to move, thereby ensuring the structural stability of the inner template 2 after being closed and formed. Under the restriction of the outer template 1 and the inner template 2, the bottom plate 3 is blocked from the bottom, so that the molding cavity becomes a ring structure with only an opening at the top. At this time, the molding mold is in a mold-closing state. The staff can place a steel frame into the molding cavity through the opening above the molding cavity, and pour concrete into the molding cavity through the opening. After the concrete solidifies, a cylindrical wind turbine tower section is formed in the molding cavity, hereinafter referred to as the section. Then the staff can open the mold and take out the material.

[0022] When opening the mold, the staff applies a pulling force from the side of the first curved plate 101 away from the first rotating shaft 102. Under the action of the pulling force, the first curved plate 101 rotates around the first rotating shaft 102 to the side away from the center of the outer template 1, so that the first curved plate 101 is separated from the outer surface of the section barrel in the molding cavity, and the two end surfaces of the two adjacent first curved plates 101 that are in contact with each other are located on the same plane as the central axis of the outer template 1, and the first rotating shaft 102 is not located in the fan-shaped range with the center of the outer template 1 as the starting point and the end surfaces on both sides of the first curved plate 101 as the limit. The first rotating shaft 102 is obliquely set on the outside of the first curved plate 101, which ensures that when the first curved plate 101 rotates around the first rotating shaft 102, the rotation trajectory of the first curved plate 101 will not invade the molding cavity, thereby ensuring the smoothness of the separation of the first curved plate 101 from the outer surface of the section barrel in the molding cavity.

[0023] Subsequently, the staff controlled the hydraulic push rod 204 to retract the telescopic end of the hydraulic push rod 204, driving the support plate 202 to move toward the center of the circle of the inner template 2. Since the angle between the two end faces of the support plate 202 and the second curved plates 201 on both sides is set to 10° (the angle is greater than or equal to 0° and less than 30°), and the opening of the angle is toward the center of the circle of the inner template 2, the top view cross-section of the structure in which the support plate 202 is clamped between the two second curved plates 201 presents an approximate trapezoid, and its width on the side close to the molding cavity is greater than its width on the side close to the center of the circle of the inner template 2, so that the hydraulic push rod 204 can smoothly drive the support plate 202 to move toward the center of the circle of the inner template 2, so that the support plate 202 is moved from the two second curved plates 201, after losing the support restriction of the support plate 202, the staff can apply a pulling force from the side of the second curved plate 201 away from the second rotating shaft 203. Under the action of the pulling force, the second curved plate 201 rotates around the second rotating shaft 203 toward the center of the inner template 2, so that the second curved plate 201 is separated from the inner surface of the section barrel in the molding cavity. The second rotating shaft 203 is not arranged in the fan-shaped area formed by the center of the inner template 2 and the outer end wall of the second curved plate 201. The second rotating shaft 203 is obliquely arranged on the outside of the second curved plate 201, which makes the second curved plate 201 The rotation trajectory will not invade the range of the molding cavity when the second curved plate 201 rotates around the second rotating shaft 203, thereby ensuring the smoothness of the separation of the second curved plate 201 from the inner surface of the section barrel in the molding cavity.

[0024] During the process of opening the mold and taking materials, the first curved plate 101 is separated from the section barrel by rotating around the first rotating shaft 102, and the second curved plate 201 is separated from the section barrel by rotating around the second rotating shaft 203. This allows it to be demoulded and separated by applying force on one side to peel it off, which can improve the demoulding convenience to a certain extent and help avoid damage to the section barrel surface during demoulding and taking materials. During the process of opening the mold, demoulding and taking materials, the various components of the molding mold move in an orderly manner and will not be scattered. Subsequently, the mold can be reset and closed by rotating to start a new round of casting production, so that the molding mold can continuously and efficiently cast the section barrel after assembly is completed, which is beneficial to improving production efficiency.

[0025] In the specific implementation process, Figure 5 and Fig. 9As shown, the lower ends of the first rotating shaft 102 and the second rotating shaft 203 are both configured as spline structures, a first spline cylinder 304 corresponding to the first plug hole 302 and a second spline cylinder 305 corresponding to the second plug hole 303 are rotatably installed in the fan-shaped plate 301, the inner size of the first spline cylinder 304 is adapted to the outer size of the lower end of the first rotating shaft 102, the inner size of the second spline cylinder 305 is adapted to the outer size of the lower end of the second rotating shaft 203, and a first servo motor 306 is fixedly installed on the outer side of the fan-shaped plate 301. 06, a first worm gear 307 is coaxially fixed to the outer side of the first spline cylinder 304, and a first worm 308 is meshed on the outer side of the first worm gear 307, a second worm gear 309 is coaxially fixed to the outer side of the second spline cylinder 305, and a second worm 310 is meshed on the outer side of the second worm gear 309, the first worm 308 is coaxially fixed to the driving shaft of the first servo motor 306, the first worm 308 and the second worm 310 are arranged in parallel, and a reversing transmission box 311 is connected between the first worm 308 and the second worm 310.

[0026] During the use of the molding die, when it is necessary to control the rotation of the first curved plate 101 and the second curved plate 201, the staff can power on the first servo motor 306, and use the first servo motor 306 to drive the first spline cylinder 304 and the second spline cylinder 305 to rotate, thereby driving the first rotating shaft 102 plugged in the first spline cylinder 304, and the second rotating shaft 203 plugged in the second spline cylinder 305 to rotate, so as to realize the rotation control of the first curved plate 101 and the second curved plate 201. By controlling the rotation direction of the driving shaft of the first servo motor 306, the rotation direction of the first curved plate 101 and the second curved plate 201 can be controlled, which can be achieved to a certain extent. In order to improve the control flexibility of the molding die during actual use, when the first servo motor 306 is powered on and started to drive the first spline cylinder 304 and the second spline cylinder 305 to rotate, the driving shaft of the first servo motor 306 rotates, driving the first worm 308 fixedly connected thereto to rotate synchronously, and the meshing transmission between the first worm 308 and the first worm wheel 307 provides power for the rotation of the first spline cylinder 304. Simultaneously, with the transmission connection of the reversing transmission box 311, the second worm 310 rotates synchronously with the first worm 308, and then with the meshing transmission between the second worm 310 and the second worm wheel 309, power is provided for the rotation of the second spline cylinder 305.

[0027] Since the lower ends of the first rotating shaft 102 and the second rotating shaft 203 are respectively configured as spline structures adapted to the internal dimensions of the first spline cylinder 304 and the second spline cylinder 305, the first spline cylinder 304 can drive the first rotating shaft 102 to rotate stably during the driven rotation process, and the second spline cylinder 305 can drive the second rotating shaft 203 to rotate stably during the driven rotation process, which is beneficial to ensuring the stability of the rotational power acting on the first curved plate 101 and the second curved plate 201. During the mold opening and closing process, the first servo motor 306 is used to drive instead of manually opening or closing the first curved plate 101 and the second curved plate Plate 201 can effectively reduce the labor burden of the staff, and when transmitting power, by means of the one-way self-locking property of the meshing transmission between the first worm 308 and the first worm wheel 307, and the one-way self-locking property of the meshing transmission between the second worm 310 and the second worm wheel 309, when the first servo motor 306 is not powered on, the first rotating shaft 102 inserted in the first spline cylinder 304, and the second rotating shaft 203 inserted in the second spline cylinder 305 cannot be driven to rotate by other external forces, so that the first arc plate 101 and the second arc plate 201 are automatically positioned and stabilized after rotation adjustment.

[0028] Under the reversing drive of the reversing transmission box 311, the first worm 308 and the second worm 310 rotate in opposite directions, so that the first spline cylinder 304 and the second spline cylinder 305 are driven to rotate in opposite directions. In the mold opening process, when the first curved plate 101 rotates around the first rotating shaft 102 in the direction away from the center of the outer template 1, the second curved plate 201 will be driven to rotate around the second rotating shaft 203 toward the center of the inner template 2. In the mold closing process, when the first curved plate 101 rotates around the first rotating shaft 102 toward the center of the outer template 1, the second curved plate 201 will be driven to rotate around the second rotating shaft 203 toward the center of the inner template 2. 1 will be driven to rotate around the second rotating shaft 203 in the direction away from the center of the inner template 2, so that the rotation of the first curved plate 101 and the second curved plate 201 are synchronously controlled without interfering with each other. During the mold opening process, the first curved plate 101 on the outside and the second curved plate 201 on the inside are synchronously rotated and uncovered, and at the same time, the demoulding separation force is applied to the inner and outer end walls of the section barrel after molding, which is conducive to ensuring that the force on the inside and outside of the section barrel is uniform during demoulding, avoiding the cracking of the section barrel due to uneven force inside and outside of the demoulding, and to a certain extent ensuring the quality of the section barrel after demoulding by the molding mold.

[0029] In the specific implementation process, Figure 1 - Figure 4 , Fig.12 and Fig.14As shown, a plurality of first brackets 4 arranged around the outside of the outer template 1 are vertically fixed on the top of the base plate 3, a first ring frame 401 coaxially arranged with the outer template 1 is fixedly installed on the top of the plurality of first brackets 4, and a first docking hole 402 corresponding to the first rotating shaft 102 is opened on the first ring frame 401, a plurality of second brackets 403 arranged around the inside of the inner template 2 are vertically fixed on the top of the base plate 3, a second ring frame 404 coaxially arranged with the inner template 2 is fixedly installed on the top of the plurality of second brackets 403, and a second docking hole 405 corresponding to the second rotating shaft 203 is opened on the second ring frame 404, a connecting plate 406 is fixedly connected between two adjacent second brackets 403, and the hydraulic push rod 204 is fixedly installed on the connecting plate 406.

[0030] During use of the molding die, with the support of a plurality of first brackets 4 arranged vertically around, the first ring frame 401 can be stably located above the outer template 1, and then with the restriction of the upper end of the first rotating shaft 102 by the first docking hole 402 in the first ring frame 401, the stability of the outer template 1 formed by the plurality of first curved plates 101 can be ensured, and the stability of the first curved plate 101 when rotating can be ensured. Similarly, with the support of a plurality of second brackets 403 arranged vertically around, the second ring frame 404 can be stably located above the inner template 2, and then with the restriction of the upper second rotating shaft 203 by the second docking hole 405 in the second ring frame 404, the stability of the inner template 2 formed by the plurality of second curved plates 201 in cooperation with the support plate 202 can be ensured, and the stability of the second curved plate 201 when rotating can be ensured. Moreover, by connecting two adjacent second brackets 403 through the connecting plate 406, not only the stability of the second bracket 403 supporting the second ring frame 404 can be further improved, but also a suitable installation position can be provided for the hydraulic push rod 204.

[0031] In the specific implementation process, Figure 1 , Figure 4 , Fig.10 and Fig.14As shown, a vertically arranged guide roller 5 is rotatably installed in each first bracket 4, a winding roller 501 is fixedly installed on the outside of one of the guide rollers 5, a second servo motor 502 is fixedly installed on the top of the first bracket 4 on which the winding roller 501 is installed, and a driving shaft of the second servo motor 502 is transmission-connected to the winding roller 501, and a pull rope 503 is fixedly connected to the side of each first curved plate 101 away from the first rotating shaft 102, and the pull rope 503 surrounds the outside of many guide rollers 5 and is fixedly connected to the winding roller 501. During the use of the molding mold, when controlling the first curved plate 101 to rotate around the first rotating shaft 1 When 02 rotates in the direction away from the center of the outer template 1, it can not only be driven and controlled by the first servo motor 306, but also a pulling force can be applied synchronously by the pull rope 503. When it is necessary to pull the first curved plate 101 outward to open the mold for mold opening operation, the staff connects the other end of the pull rope 503 connected to the first curved plate 101 to the winding roller 501, and then controls the second servo motor 502 to power on and start, driving the winding roller 501 to rotate to reel in the pull rope 503. The pulling force generated by the reeling acts on the first curved plate 101, which can assist in better separation of the first curved plate 101 from the surface of the section cylinder when opening the mold.

[0032] When controlling the first curved plate 101 to rotate and open the mold, the first servo motor 306 and the second servo motor 502 need to be started synchronously to keep the first rotating shaft 102 rotating to drive the first curved plate 101 to open, and the pull rope 503 pulling to assist the first curved plate 101 to open in coordination. The staff can control the first curved plates 101 to rotate and open one by one according to actual needs, or can also control all the first curved plates 101 to rotate and open synchronously. When the first curved plates 101 are driven to rotate and open one by one, the first curved plates The single pull rope 503 corresponding to 101 is firmly connected to the winding roller 501. When it is necessary to control all the first curved plates 101 to rotate and open at the same time, all the pull ropes 503 are orderly wound around the outside of the plurality of guide rollers 5 in the same direction. After being guided by the guide rollers 5, they are firmly connected to the winding roller 501. After being connected, the plurality of pull ropes 503 are in a taut state. Under the traction of the pull ropes 503, the plurality of first curved plates 101 can be assisted to be pulled open together, which is conducive to ensuring the operational flexibility of the molding mold during actual use.

[0033] In the specific implementation process, Figure 1 and Fig.11As shown, an assembly platform 6 is provided at the bottom of the base plate 3, and the assembly platform 6 includes a central platform 601 arranged in the middle position, and a plurality of extension beams 602 extending outward are fixed around the outer side of the central platform 601, and a plurality of evenly distributed spiral support legs 603 are fixedly installed at the bottom of the central platform 601 and the extension beam 602. During the use of the molding mold, the assembly platform 6 is used for support at the bottom, and the horizontality of the top of the assembly platform 6 can be adjusted with the help of the numerous evenly distributed spiral support legs 603 at the bottom of the central platform 601 and the extension beam 602. The spiral support legs 603 can be composed of a screw barrel and a screw rod that are screwed together. By relatively rotating the screw barrel and the screw rod, the actual length of the spiral support legs 603 is driven to change, and support is provided at the bottom of the central platform 601 and the extension beam 602, so that the assembly platform 6 can provide horizontal support for the upper outer formwork 1, inner formwork 2 and base plate 3 on uneven ground, which is beneficial to ensure the stability of the section tube casting and molding.

[0034] In the specific implementation process, Figure 1 - Fig.14 As shown, the first ring frame 401 and the second ring frame 404 are both composed of a plurality of arc-shaped beams distributed in a surrounding manner, and the two adjacent sector plates 301, the first bracket 4, the second bracket 403 and the sector plate 301, the two adjacent arc-shaped beams, the second bracket 403 and the connecting plate 406, and the central platform 601 and the extension beam 602 are all fastened and connected by bolts. During the use of the molding mold, the above-mentioned structural arrangement allows the molding mold to be flexibly disassembled and assembled. By disassembling and assembling the bolts at the connecting structure, the molding mold can be decomposed into a plurality of relatively independent small structures during transportation, which is convenient for transportation and storage. When needed, it can be modularly assembled and quickly assembled, which is conducive to improving the convenience of the molding mold in actual use.

[0035] Specifically, the working principle and operation method of the present invention are as follows: The forming mold can be assembled and formed by plugging and bolting at the connection position. By adjusting the support height of each spiral support leg 603, it is ensured that the forming mold can be used for casting and producing the section tube in a horizontal environment. When the mold is closed, the numerous surrounding first arc plates 101 are closed to form a closed outer template 1, and the numerous surrounding second arc plates 201 and support plates 202 constitute a closed inner template 2. The outer template 1, the inner template 2 and the bottom plate 3 cooperate to form a forming cavity for casting the section tube. The staff puts a steel frame into the forming cavity and pours concrete. After solidification, a section tube is formed. When the mold is opened, the hydraulic push rod 204 is powered on and started to control the support plate 202 to move toward the center of the inner template 2, so that the support plate 202 withdraws from between the two second arc plates 201. Subsequently, the first servo motor 306 and the second servo motor 502 are simultaneously When the power is turned on and the first servo motor 306 is started, the first worm 308 and the second worm 310 rotate synchronously relative to each other with the help of the reversing transmission of the reversing transmission box 311, and then the first spline cylinder 304 and the second spline cylinder 305 rotate synchronously relative to each other with the help of the meshing transmission of the first worm 308 and the first worm wheel 307, and the meshing transmission of the second worm 310 and the second worm wheel 309, so as to control the first rotating shaft 102 to drive the first arc plate 101 to rotate and open, and control the second rotating shaft 203 to drive the second arc plate 201 to rotate and open. During the rotation and opening process of the first arc plate 101, the second servo motor 502 drives the winding roller 501 to rotate and rewind the pull rope 503. Under the guidance of the guide roller 5, the pull rope 503 applies an outward auxiliary pulling force to the first arc plate 101, so as to achieve a smoother mold opening and separation operation.

[0036] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
