[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] In one embodiment, see Figure 1 The utility model provides a wind turbine foundation reinforcement steel cable limiting device, which includes a steel template 1, a limiting component, and a supporting component.

[0021] Among them, the steel formwork 1 includes an arc-shaped steel plate 101 and an angle steel frame 102 arranged on the arc surface of the steel plate 101; the limiting component includes a limiting plate 2 arranged on the arc surface of the steel plate 101, and a limiting groove 3 is provided on the limiting plate 2. The height of the limiting plate 2 is greater than the height of the angle steel frame 102, and the distance from the bottom end of the limiting groove 3 to the steel plate 101 is consistent with the height of the angle steel frame 102, so that the bottom end of the limiting groove 3 and the end face of the angle steel frame 102 away from the steel plate 101 are located on the same arc surface; the supporting component includes a detachable supporting arc plate 4 arranged on two adjacent limiting plates 2, the supporting arc plate 4 is clamped with the angle steel frame 102, and a supporting groove 5 consistent with the limiting groove 3 is provided on the supporting arc plate 4, and a support member 6 is provided on the supporting arc plate 4; the support groove 5 and the limiting groove 3 are located on the same arc surface; the support member 6 is located at the lower end of the support groove 5, and the upper end face of the support member 6 is flush with the lower end face of the support groove 5.

[0022] For further information, see Figure 2 , three groups of limit plates 2 are arranged in sequence from top to bottom, two groups of limit plates 2 are arranged adjacent to the bottom end of the steel plate 101, and another group of steel templates 1 is arranged adjacent to the top end of the steel plate 101. The distance between the two groups of limit plates 2 located at the bottom end of the steel plate 101 is smaller than the distance between the limit plate 2 located at the top end of the steel plate 101 and the limit plate 2 located in the middle.

[0023] Preferably, the limiting plate 2 is arc-shaped, and the limiting groove 3 is arranged on the arc surface of the limiting plate 2.

[0024] Preferably, the curvature of the limiting plate 2 is consistent with the curvature of the steel plate 101 .

[0025] In the above-mentioned setting, three groups of limit plates 2 are set, and two groups of limit plates 2 are located at the lower end of the steel plate 101. During the process of pouring concrete for the circular support wind turbine foundation by assembling multiple groups of steel formworks 1, since the concrete exerts a large force on the lower part of the steel formwork 1, the two groups of limit plates 2 located at the lower end of the steel formwork 1 cooperate with the steel cables to better provide support and protection.

[0026] For further information, see Figure 2 , vertical downward slots 7 are provided at both ends of the limit plate 2, and the slots 7 do not pass through the limit plate 2; both ends of the supporting arc plate 4 are provided with convex plates 8 corresponding to the slots 7, and a vertical groove 9 is also provided in the middle of the inner arc end surface of the supporting arc plate 4.

[0027] Preferably, a gap is left between the two ends of the limiting plate 2 and the angle steel frame 102 , and the gap can be filled by the portion between the convex plate 8 and the vertical groove 9 on the supporting arc plate 4 .

[0028] In the above setting, the vertical groove 9 on the supporting slide is inserted into the angle steel frame 102 tightly attached to the two adjacent steel formworks 1, and the convex plate 8 is inserted into the slot 7 from top to bottom, thereby clamping the supporting arc plate 4 with the steel formwork 1 and the limiting plate 2. At this time, the supporting groove 5 and the limiting groove 3 are located on the same arc surface.

[0029] For further information, see Figure 3 , the supporting groove 5 passes through the vertical groove 9.

[0030] Preferably, the corresponding positions of the supporting groove 5 and the vertical groove 9 are interconnected.

[0031] In the above setting, after the support groove 5 passes through the vertical groove 9, the two groups of angle steel frames 102 located in the vertical groove 9 are exposed in the support groove 5. When the reinforcing steel cable is located in the limiting groove 3 and the reinforcing steel formwork 1 in the support groove 5, the reinforcing steel cable abuts against the angle steel frame 102 and applies a force.

[0032] For further information, see Figure 3 The support member 6 includes a support plate 601 , the upper end surface of the support plate 601 is flush with the lower end surface of the support groove 5 , and a baffle 10 is provided at one end of the support plate 601 away from the supporting arc plate 4 .

[0033] Preferably, an “L”-shaped structure is formed between the support plate 601 and the baffle 10 , and the baffle 10 is located on the upper end surface of the support plate 601 .

[0034] In the above-mentioned setting, after the steel formwork 1 is installed, the reinforcing steel cable can be placed on the support plate 601 and limited by the baffle 10, so that the ring-shaped reinforcing steel cable can be placed on the support plate 601 as a whole, and adjacent to the support groove 5 and the limiting groove 3, thereby providing support and guidance for the reinforcing steel cable. During the tightening process of the reinforcing steel cable, the reinforcing steel cable moves along the support plate 601 into the support groove 5 and the limiting groove 3, thereby ensuring that the reinforcing steel cable is located on the same arc surface after tightening.

[0035] In this embodiment, after the steel formwork 1 is installed, multiple groups of steel formworks 1 are in a circular ring shape, and multiple groups of limiting plates 2 are also in a circular ring shape. The supporting arc plate 4 is clamped in the angle steel frame 102 of the two groups of steel formworks 1 through the vertical groove 9, and the lower supporting arc plate 4 is clamped in the clamping groove 7 through the convex plate 8, thereby connecting the supporting arc plate 4 with the two adjacent groups of limiting plates 2. Multiple groups of supporting arc plates 4 are connected to multiple limiting plates 2 into a ring shape, and the reinforcing steel cable is placed on the support plate 601 and limited by the baffle 10. Since the upper end face of the support plate 601 and the lower end faces of the limiting groove 3 and the support groove 5 are located on the same arc surface, during the process of tightening the reinforcing steel cable, the reinforcing steel cable enters the limiting groove 3 and the support groove 5 to provide support for the steel formwork 1.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
