[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] like Figures 1 to 14 As shown, the prefabricated steam curing hood structure for wind turbine tower segments of this invention includes a curing hood 1 and a transfer device 2. Steam is injected into the curing hood 1 to cure the segments 3 inside the hood 1. The specific structure of the curing hood 1 can be found in existing technology, so it will not be described in detail here.

[0019] The transfer device 2 is used to place the pipe segments 3, enabling the stacking of pipe segments 3. Multiple pipe segments 3 can be stacked at once, thus achieving the curing of multiple pipe segments 3 at one time. The pipe segments 3 can be pre-placed outside the curing cover 1, and then the loaded pipe segments 3 are towed into the curing cover 1 by a tractor.

[0020] When the transfer device 2 is in use, because the bearing components 4 are arranged in multiple layers and are connected to each other by bolts to maintain a stacked arrangement, when placing the tube segments 3, the bottommost bearing component 5 can be pushed out from the second movable groove 6 first to support the tube segment 3. Then, after the bottom is full, the bearing components 5 are pushed out one by one to place the tube segments 3 sequentially. When removing the cured tube segments 3, the process can start from the top, removing the tube segments 3 first, and then using the movable component 7 to drive the bearing components 5 into the second movable groove 6 for concealment, and then gradually removing the tube segments 3 layer by layer. This allows for the stacking of tube segments 3, enabling the curing of more tube segments 3 at once.

[0021] Meanwhile, it adopts a linkage structure, which can change the position of the bearing 5 in this layer through the movable part 7, so as to expose or hide it without affecting the segments 3 of other layers.

[0022] The curing cover 1 has a hollowed-out center to form a curing area 8. The transfer device 2 is pushed into this area to inject steam. The cover is then closed to maintain the temperature of the steam inside. The transfer device 2 can be moved using guide rails and a tractor.

[0023] The transfer device 2 is located inside the curing hood 1. The transfer device 2 is used to transport the tube segments 3 that require steam curing. The transfer device 2 includes a support plate 9 and a support assembly 4, with the support assembly 4 mounted on the support plate 9. Multiple rollers 10 are provided at the bottom of the support plate 9. The support components 4 are symmetrically arranged on the support plate 9, and several support components 4 are arranged. The number of stacked components can be set according to actual needs.

[0024] The support components 4 form a support area 11 for placing the tube segments 3 between the support components 4, and the support components 4 are symmetrically arranged and stacked.

[0025] The load-bearing assembly 4 comprises a load-bearing beam 12, a movable component 7, and several load-bearing components 5. The load-bearing beam 12 is stacked, and the movable component 7 is correspondingly positioned to the load-bearing beam 12. The load-bearing components 5 are hinged between the load-bearing beam 12 and the movable component 7. One end of the load-bearing beam 12 is provided with a first baffle 13, and the other end is provided with a second baffle 14, which are positioned opposite each other. One end of the movable component 7 is limited by cooperating with the first baffle 13 through a first movable rod 15, and the other end is limited by cooperating with the second baffle 14 through a second movable rod 16.

[0026] A plurality of first movable grooves 17 are provided in the middle of the movable component 7, and a plurality of second movable grooves 6 are provided in the middle of the bearing beam 12. The bearing component 5 is set in the first movable groove 17 through the first hinge rod 18 and in the second movable groove 6 through the second hinge rod 19. The bearing component 5 is provided with a third movable groove 20 that cooperates with the first hinge rod 18.

[0027] When in use, when the movable part 7 is pushed, the movable part 7 drives the bearing part 5 to rotate around the second hinge rod 19, while the first hinge rod 18 changes position in the third movable groove 20, and the part of the bearing part 5 that extends into the bearing area 11 is rotated into the second movable groove 6 and hidden.

[0028] like Figure 10As shown, a first slot 21 and a first limiting rod 22 are provided on the first baffle 13. The first movable rod 15 is inserted into the first slot 21, and a first gap 23 is formed between the first baffle 13 and the supporting beam 12. The first gap 23 is used to place the first tension spring 24. The first baffle 13 is used to limit the position of the first spring 25, and the first slot 21 is used to keep the first movable rod 15 moving within it, so that the movable part 7 can move away from or towards the supporting beam 12.

[0029] The first tension spring 24 is disposed within the first gap 23. One end of the first tension spring 24 is disposed on the first limiting rod 22, and the other end is disposed on the first movable rod 15. The first tension spring 24 can pull the movable member 7 back when it moves away from the bearing beam 12, thereby causing the movable member 7 to push the bearing member 5 to rotate around the second hinge rod 19. This allows the bearing end 26 exposed in the bearing area 11 to be rotated into the second movable groove 6 and hidden, so as not to obstruct the lower end of the tube segment 3. This ensures that the lower end of the tube segment 3 will not be blocked by the upper end of the bearing member 5 and cannot be lifted out when the tube segment 3 is hoisted, thus ensuring the stacking of the tube segments 3.

[0030] like Figure 6 As shown, a nut 27 and a first spring 25 are provided on the first movable rod 15. One end of the first spring 25 contacts the nut 27, and the other end contacts the first baffle 13. The first spring 25 is located at the opposite end of the first gap 23. The first spring 25 cooperates with the second spring 28 to push the movable part 7, so that it can drive the bearing part 5 to rotate around the second hinge rod 19.

[0031] like Figure 8 As shown, a second gap 29 is formed between the second baffle 14 and the supporting beam 12. A second limiting rod 30 is provided on the second baffle 14. The second limiting rod 30 is located at the opposite end of the second gap 29, that is, the second gap 29 is located on one side of the second baffle 14, while the second limiting rod 30 is located on the other side of the second baffle 14.

[0032] Furthermore, a second spring 28 is fitted onto the second movable rod 16, and the second spring 28 is disposed within the second gap 29.

[0033] The second baffle 14 is provided with a second strip groove 31, and the second movable rod 16 is inserted into the second strip groove 31. A second tension spring 32 is provided between the second movable rod 16 and the second limiting rod 30. The first tension spring 24 cooperates with the second tension spring 32 to pull the movable part 7 closer to the bearing beam 12, thereby cooperating with the first spring 25 and the second spring 28 to realize the rotation of the bearing part 5, and keep the bearing end 26 on the bearing part 5 able to rotate into the second movable groove 6.

[0034] like Figure 11 , 12As shown in Figure 13, the movable part 7 is provided with an extension arm 33 at one end near the second movable rod 16. The extension arm 33 is provided with a limiting protrusion 34. One end of the bearing beam 12 is provided with a limiting groove 35 that cooperates with the limiting protrusion 34. The limiting groove 35 is located in the second gap 29.

[0035] The movable component 7 consists of a bearing end 26, a hinge section 36, and a guide section 37. The bearing end 26 has a bearing surface 38 that mates with the tube segment 3. A first hinge rod 18 and a second hinge rod 19 are disposed on the hinge section 36, and a third movable groove 20 is disposed on the hinge section 36 and the guide section 37, with the guide section 37 being inclined. The thickness of the movable component 7 is greater than the height of the second movable groove 6, and the thickness of the limiting protrusion 34 is exactly matched with the height of the second movable groove 6, allowing the limiting protrusion 34 to enter the second movable groove 6.

[0036] like Figure 14 As shown, the carrier 5 is currently supporting the tube segment 3. Simultaneously, the first spring 25 and the second spring 28 are compressed, while the first tension spring 24 and the second tension spring 32 are in their natural state. The limiting protrusion 34 is restrained within the limiting groove 35 by the elastic force of the first spring 25 and the second spring 28, thus limiting the position of the movable part 7. When it is necessary to rotate the carrier 5 to hide it within the second movable groove 6, the movable part 7 can be pushed in the direction of F1 first, causing the limiting protrusion 34 to move out of the limiting groove 35 and into the second gap 29. At this time, the first spring 25 and the second spring 28 are further compressed a certain distance. Then, the movable part 7 is pulled by the staff to move it in the direction of F2, and stretches the first tension spring 24 and the second tension spring 32. At the same time, the first spring 25 and the second spring 28 push the movable part 7 in the direction of F3 under their own elastic force. At this time, the bearing part 5 can rotate around the second hinge rod 19, while the first hinge rod 18 moves in the third movable groove 20 and changes position, while driving the bearing part 5 to rotate around the second hinge rod 19, so that the bearing end 26 on the bearing part 5 rotates into the second movable groove 6.

[0037] Finally, the tension on the movable part 7 is released. At this point, under the tension of the first tension spring 24 and the second tension spring 32, the movable part 7, in conjunction with the elastic force of the first spring 25 and the second spring 28, moves towards direction F4. The movable part 7 then approaches the supporting beam 12 and drives the supporting part 5 to rotate, causing the limiting protrusion 34 to enter the second movable groove 6. After the movable part 7 drives the supporting part 5 into the second movable groove 6, the movable part 7 is now close to the supporting beam 12, and the first tension spring 24 and the second tension spring 32 are in their natural state, as are the first spring 25 and the second spring 28, and are not subject to external force.

[0038] When it is necessary to rotate the bearing member 5, first pull the movable member 7 to move it away from the bearing beam 12. Then move the movable member 7 towards the second baffle 14 to compress the first spring 25 and the second spring 28. With the pulling force of the first tension spring 24 and the second tension spring 32, the limiting protrusion 34 on the movable member 7 enters the second gap 29. Then, under the push of the elastic force of the first spring 25 and the second spring 28, the limiting protrusion 34 enters the limiting groove 35, completing the rotation of the rotating member and allowing the bearing end 26 to reach the bearing area 11.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
