The cover plate assembly 5 includes a cover plate 51 and cover plate legs 52. Hinged plates 53 are symmetrically installed on both sides of the cover plate 51. The hinged plates 53 are hinged to the cover plate legs 52 via hinge shafts 54. The cover plate legs 52 are installed on the bottom mold 1, as shown. Figure 5 and Figure 6 As shown, a long slot 7 is provided at the position of the hinge shaft 54 ​​hole of the cover plate support leg 52, and several attached gas vibrators are provided on both sides of the bottom surface of the bottom mold 1. Limiting devices are provided at the connection between the side mold and the bottom mold 1, and between the end mold 4 and the bottom mold 1 to limit the opening angle of the side mold and the end mold 4, so as to ensure the safety of the operation when the mold is opened.

[0031] Specifically, such as Figure 3 As shown, each set of inserts 6 includes one bottom side mold insert 62, one top side mold insert 63, and two end mold inserts 64; the width w and thickness d of the inserts 6 in the same set are the same. The width w of the set of inserts 6 with a larger outer diameter is greater than the width d of the set of inserts 6 with a smaller outer diameter. By adjusting the width w of the inserts 6, the thickness of the precast component produced by the mold is adjusted, thereby changing the outer diameter of the precast component, so that the same set of molds can be used for multiple tower segment specifications.

[0032] Specifically, such as Figure 7 and Figure 8 As shown, when the insert 6 is installed into the groove, the insert 6 is fastened to the groove by bolts. The outer arc sides of the bottom side mold 2, the top side mold 3 and the two side end molds 4 are respectively provided with several through holes for installing fastening bolts 13. The corresponding positions on the insert 6 are provided with threaded holes. The end mold 4 or the side mold is fastened to the corresponding insert 6 by fixing bolts. This is equivalent to fixing the insert 6 in the groove corresponding to the insert by bolts, thus achieving the fastening connection between the end mold 4 and the end mold insert 64, the top side mold 3 and the top side mold insert 63, and the bottom side mold 2 and the bottom side mold insert 62.

[0033] Specifically, the through holes on each end mold 4 or side mold are divided into two groups. One group of through holes is used to install a group of inserts 6 with a larger outer diameter, and the other group of through holes is used to install a group of inserts 6 with a smaller outer diameter.

[0034] Specifically, such as Figure 6 and Figure 8 As shown, in the two sets of inserts 6, when the set of inserts 6 with the larger outer diameter is installed into the groove of the end mold 4 or the side mold, the insert 6 forms a Z-shaped contact surface with the groove, and the hinge shaft 54 ​​is fixed above the long slot 7 of the cover plate support leg 52 by bolts; as Figure 5 and Figure 7As shown, when a set of inserts 6 with a smaller outer diameter is installed into the groove of the end mold 4 or the side mold, the inserts 6 and the groove form an L-shaped contact surface, and the hinge shaft 54 ​​is fixed to the lower part of the long slot 7 of the cover plate support leg 52 by bolts.

[0035] Specifically, the two cover plate assemblies 5 are symmetrically arranged, and an opening for injecting concrete is formed between the two cover plates 51.

[0036] Specifically, several cover plate 51 fasteners are provided on both sides and the lower end of cover plate 51 for fastening cover plate 51 to the side mold and the end mold 4 when cover plate 51 is closed.

[0037] Example 2

[0038] As a further improvement to Embodiment 1, the attached gas vibrators are arranged in a zigzag pattern on both sides of the bottom surface of the bottom mold 1. The air inlets of the attached vibrators on the same side face the same direction, while the air inlets of the attached vibrators on both sides face opposite directions. This arrangement of the attached gas vibrators ensures a more uniform distribution of the vibration force, effectively eliminates air bubbles in the concrete, and ensures the strength of the component. Furthermore, this arrangement of the air inlets facilitates the connection of the air distribution pipes.

[0039] Example 3

[0040] As a further improvement to Embodiment 2, several adjustable leveling supports 11 are provided on the bottom sides of the bottom mold 1.

[0041] Specifically, a walkway is installed on the outside of the bottom mold 1 for workers to open and close the cover plate 51, which facilitates the opening and closing of the mold.

[0042] Specifically, the bottom mold 1 and the side mold are provided with opening and closing bolts 12 and fastening bolts 13. The opening and closing bolts 12 are positive and negative thread bolts. The bottom mold 1 is provided with a negative thread nut corresponding to the positive and negative thread bolt, and the side mold is provided with a positive thread nut corresponding to the positive and negative thread bolt.

[0043] Example 4

[0044] As a further improvement of embodiment 3, a torsion spring 55 for assisting the opening and closing of the cover plate 51 is provided at the hinge joint between the cover plate 51 and the cover plate support leg 52. One torsion bar of the torsion spring 55 is installed on the cover plate support leg 52, and the other torsion bar of the torsion spring 55 is installed on the hinge plate 53.

[0045] The specific working state of the horizontal mold for wind power concrete tower provided by this utility model is as follows:

[0046] When closing the mold, the foundation is first leveled using the adjustable leveling support 11 to ensure the mold is in a horizontal production state. Then, the insert 6 is installed into the corresponding groove. A suitable set of through holes is selected according to the outer diameter of the insert 6, and the insert 6 is fixed with bolts. After the insert 6 is installed, the end mold and side mold are closed. The closing sequence is to close the end mold 4 first, then the side mold. After closing the mold, the release agent is evenly applied to the cavity of the mold. After application, the reinforcing cage is placed in, and the two side cover plates 51 are closed and tightened.

[0047] Concrete is injected into the mold through the opening formed between the two side cover plates 51. During the injection process, the attached vibrator is activated to ensure that the concrete can quickly and evenly fill the cavity, while simultaneously vibrating out air bubbles to guarantee the quality of the precast component. After filling, the component is allowed to solidify. Once the component reaches the required strength, the mold is opened. The opening sequence is as follows: first, open the two side cover plates 51; then, open the side molds; and finally, open the end molds. Limiting devices are installed at the connections between the side molds and the bottom mold 1, and between the end mold 4 and the bottom mold 1, to limit the maximum opening angle of the side molds and end mold 4, ensuring safe demolding of the precast component. Once the cover plates 51, side molds, and end molds 4 are fully opened, the component is lifted out of the mold, completing the mold making and demolding process.

[0048] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
