[0002] As a clean energy source, with the gradual development of onshore wind farms in recent years, the height of wind towers has been increasing day by day. New steel-concrete composite towers with greater stiffness have gradually become the mainstream. Among them, the concrete tower barrel sections are mostly prefabricated in factories and assembled on site, and are often fabricated in pieces for easy transportation.

[0003] The current mold for manufacturing a wind turbine tower usually consists of a base, an outer mold, an inner mold, and two sets of side plates. That is, the inner mold is fixed to the base by bolts, and the outer mold is hoisted outside the inner mold. Together with the two side plates, a closed casting space with an open top is formed, and then concrete can be poured into this space to manufacture the required concrete tower barrel section. Subsequently, the outer mold, the inner mold, and the two side plates are lifted by a crane and moved away from the finished concrete tower barrel section to complete demolding.

[0004] The mold closing and opening actions need to rely on a crane, which not only affects the efficiency and effect of mold closing and opening, but also easily causes the collision and deformation of the mold, and there is also a safety risk of the mold falling and injuring people. Therefore, a mold for manufacturing a wind turbine tower is proposed to solve the above problems. Summary of the Utility Model

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0026] The following gives specific embodiments.

[0027] Please refer to Figures 1-5 , the present invention provides a manufacturing mold for a wind turbine tower, including a base 1; an inner mold 2 and an outer mold 3 are arranged on the top of the base 1, a positioning rod 4 is rotatably connected to the top of the outer mold 3, a rack 6 is fixedly connected to the top end of the positioning rod 4, and a limiting block 5 is fixedly connected to the top of the outer mold 3;

[0028] A transmission mechanism 7 is provided on the base 1. The transmission mechanism 7 includes a transmission frame 71 slidably connected to the top of the base 1. A positioning plate 72 is slidably connected inside the transmission frame 71. One end of the positioning plate 72 extends out of the transmission frame 71 and is fixedly connected to one side member of the outer mold 3. A positioning groove is formed on the inner side wall of the inner mold 2. The inner bottom wall of the positioning groove is rotatably connected to a transmission block 73 through a rotating shaft. One end of the transmission block 73 extends out of the positioning groove and is fixedly connected to a side plate 74. The top of the side plate 74 is rotatably connected to a gear 75 through a transmission rod. The gear 75 is meshed with a rack 6. During operation, through the setting of the transmission mechanism 7, the method of pulling the outer mold 3 can be used to replace hoisting. During this process, the two side plates 74 are unfolded synchronously, simplifying the demolding steps and improving the production efficiency. That is, the inner mold 2 is pre-installed and fixed on the base 1, and the outer mold 3 is connected and positioned on the base 1 through the positioning plate 72 and the transmission frame 71. This setting enables the outer mold 3 to be disassembled and replaced. Subsequently, the transmission frame 71 is pushed to move by an external driving device, so that the outer mold 3 approaches the inner mold 2. During this process, the gear 75 contacts the rack 6, and the rack 6 drives the gear 75 to rotate. The gear 75 drives the side plate 74 to rotate through the transmission rod, so that the two side plates 74 are attached to both sides of the outer mold 3 and the inner mold 2, and the outer mold 3, the inner mold 2 and the two side plates 74 form a precast injection mold. Then, concrete can be injected into the injection mold until the precast part is formed. The driving device drives the transmission frame 71 to move, so that the transmission frame 71 drives the outer mold 3 to move away from the inner mold 2 for demolding. At the same time, the rack 6 drives the gear 75 to reverse, and the gear 75 drives the side plate 74 to flip through the transmission rod, so that the side plate 74 flips to the inside of the inner mold 2. Demolding can be completed without removing the side plate 74. Repeat the above steps to manufacture the precast concrete tower barrel section.

[0029] Further, as Figure 2 and Figure 3 shown, a first magnetic block 8 is fixedly connected to one side surface of the rack 6 close to the limit block 5, and a second magnetic block is fixedly connected to one side surface of the limit block 5 close to the rack 6. During operation, through the setting of the first magnetic block 8 and the second magnetic block, the opposite side surfaces of the first magnetic block 8 and the second magnetic block are set to the same level. Under the repulsive force of the same level between the magnetic blocks, when the rack 6 is separated from the contact with the gear 75, it can automatically spread and flip, without manually flipping the rack 6, further simplifying the operation steps.

[0030] Further, as Figure 1 and Figure 4 shown, an auxiliary groove is formed at the bottom of the side plate 74. An auxiliary roller 9 is rotatably connected to the inner side wall of the auxiliary groove through a rotating shaft. During operation, through the setting of the auxiliary groove and the auxiliary roller 9, the rotation of the side plate 74 can be assisted, and the pressure of the gear 75 driving the gear 75 can be reduced.

[0031] Further, as Figure 2 and Figure 5As shown in the figure, a guiding groove is formed at the bottom of the driving frame 71, and a guiding wheel 10 is rotatably connected to the inner side wall of the guiding groove through a rotating shaft. During operation, through the arrangement of the guiding groove and the guiding wheel 10, the driving frame 71 can be assisted to drive the outer mold 3 to move, reducing the wear of the driving frame 71.

[0032] Furthermore, as Figure 2 and Figure 3 shown in the figure, a connecting block 11 is rotatably connected to the top of the inner mold 2 through a rotating shaft. A connecting hole is formed in the top of the outer mold 3, and a fixing block 12 is slidably connected in the connecting hole. The top end of the fixing block 12 is elastically connected to the inner bottom wall of the connecting hole through a spring 13. The top end of the fixing block 12 extends out of the connecting hole and is inserted into a through hole formed at the bottom of the connecting block 11. During operation, through the arrangement of the connecting block 11, the fixing block 12 and the spring 13, the outer mold 3 and the inner mold 2 can be easily pulled mutually, reducing the possibility of their collapse. That is, after the outer mold 3 is close to the inner mold 2, the connecting block 11 is rotated so that one end of the connecting block 11 moves onto the outer mold 3, and the top end of the fixing block 12 is inserted into the through hole, so that the outer mold 3 and the inner mold 2 are mutually restricted through the connecting block 11.

[0033] Furthermore, as Figure 4 shown in the figure, a mounting hole 14 is formed in the inner bottom wall of the inner mold 2, and the inner mold 2 is fixedly connected to the base 1 through bolts. During operation, through the arrangement of the mounting hole 14, the inner mold 2 can be detachably replaced.

[0034] Furthermore, as Figure 1 and Figure 4 shown in the figure, a sealing gasket is arranged on the outer wall of the side plate 74, and a mounting plate 15 is fixedly connected to the inner side wall of the inner mold 2. A vibration motor is mounted on the mounting plate 15. During operation, through the arrangement of the mounting plate 15 and the vibration motor thereon, the concrete poured between the outer mold 3 and the inside is more evenly mixed, thereby improving the quality of the precast member.

[0035] Working principle: The inner mold 2 is pre-installed and fixed on the base 1, and the outer mold 3 is connected and positioned on the base 1 through the positioning plate 72 and the transmission frame 71. This setting enables the disassembly and replacement of the outer mold 3. Subsequently, the transmission frame 71 is pushed by an external driving device to move, so that the outer mold 3 approaches the inner mold 2. During this process, the gear 75 contacts the rack 6, and the rack 6 drives the gear 75 to rotate. The gear 75 drives the side plate 74 to rotate through the transmission rod, so that the two side plates 74 are attached to both sides of the outer mold 3 and the inner mold 2, and the outer mold 3, the inner mold 2 and the two side plates 74 form a precast injection groove. Then, concrete can be injected into the injection groove until the precast is formed. The driving device drives the transmission frame 71 to move, so that the transmission frame 71 drives the outer mold 3 to move away from the inner mold 2 for demolding. At the same time, the rack 6 drives the gear 75 to reverse, and the gear 75 drives the side plate 74 to flip through the transmission rod, so that the side plate 74 flips to the inner side of the inner mold 2. Demolding can be completed without removing the side plate 74. Repeat the above steps to manufacture precast concrete tower barrel segments.

[0036] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
