Description

Technical Field

[0001] This utility model relates to the field of wind power hybrid tower construction, and in particular to a prestressed fixed end pad for wind power hybrid towers. Background Technology

[0002] In the field of wind power hybrid tower construction, prestressing technology is widely used to enhance the stability of the tower structure. As a key component of the prestressing system, the connection effect between the fixed end plate and the anchor directly affects the load-bearing capacity and safe service life of the entire hybrid tower. It is necessary to ensure accurate positioning and firm fixation during the connection process.

[0003] The existing technology has the following defects: some fixed structures rely only on a single bolt connection and lack auxiliary snap-fit ​​reinforcement structures. Under long-term wind power load, the connection between the anchor and the pad is prone to loosening, which reduces the overall fixing stability. In addition, the existing connection method between the fixed end pad and the anchor often has the problem of insufficient positioning convenience. The anchor is prone to horizontal displacement, which makes it difficult to accurately connect the subsequent fixing process. Therefore, a prestressed fixed end pad for wind power hybrid towers is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a prestressed fixed end pad for wind power hybrid towers, which aims to improve the problem of the simple connection structure between the pad and the anchor in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prestressed fixed end pad for a wind power hybrid tower, comprising a pad, an anchor contacting the top of the pad, a bolt threadedly connected to the inner wall of the anchor, a sleeve fixedly connected to the inner wall of the pad, an inclined block slidably connected to the inner wall of the pad, and a locking block fixedly connected to the top of the inclined block.

[0006] As a further description of the above technical solution: The top of the pad is fixedly connected to a positioning block, and the bottom of the anchor is provided with a rectangular groove.

[0007] As a further description of the above technical solution: The bolt is threaded onto the inner wall of the sleeve.

[0008] As a further description of the above technical solution: An inclined surface is provided on the upper right side of the inclined block, and the bottom end of the bolt is in contact with the inclined surface.

[0009] As a further description of the above technical solution: The locking block is slidably connected to the inner wall of the pad, and the locking block is engaged with the inner wall of the anchor.

[0010] As a further description of the above technical solution: The positioning block is inserted into the inner wall of the rectangular groove.

[0011] This utility model has the following beneficial effects: 1. In this utility model, by tightening the bolts to compress the inclined blocks, the four sets of inclined blocks are brought together and locked into the anchor slot. At the same time, the locking blocks are used to enhance the fixation. The bolts achieve the main fixation, and the locking structure strengthens the connection stability and improves the overall fixation effect.

[0012] 2. In this utility model, manually aligning the rectangular groove with the positioning block and moving it down to insert it can quickly complete the horizontal positioning of the anchor, avoid its horizontal deviation, lay a precise foundation for subsequent bolt fixing, improve the convenience and accuracy of the initial positioning of the connection, and reduce the tedious steps of subsequent manual adjustment of the position.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-3This utility model provides an embodiment of a prestressed fixed end pad for a wind power hybrid tower, comprising a pad 1, which serves as the basic load-bearing component of the entire fixed end and provides an installation support surface for the anchor 2. The top of the pad 1 contacts the anchor 2, and the contact between the anchor 2 and the top of the pad 1 enables the transfer and anchoring of prestress. The inner wall of the anchor 2 is threaded with a bolt 6, and the anchor 2 is provided with a thread that matches the bolt 6. The inner wall of the pad 1 is fixedly connected with a sleeve 3, and the inner wall of the pad 1 is slidably connected with an inclined block 4. The pad 1 has a slot corresponding to the inclined block 4, allowing the inclined block 4 to move left and right. The top of the inclined block 4 is fixedly connected with a locking block 5.

[0017] Reference Figures 1-3 The top of the pad 1 is fixedly connected to a positioning block 7, and the bottom of the anchor 2 is provided with a rectangular groove 8. The positioning block 7 is inserted into the inner wall of the rectangular groove 8, which can accurately limit the horizontal displacement of the anchor 2 at the top of the pad 1 and ensure the accuracy of the installation position of the anchor 2. The positioning block 7 is inserted into the inner wall of the rectangular groove 8.

[0018] Reference Figures 2-4 Bolt 6 is threaded onto the inner wall of sleeve 3. Sleeve 3 has a thread that matches bolt 6. An inclined surface is provided on the upper right side of inclined block 4. The bottom end of bolt 6 contacts the inclined surface. When bolt 6 presses against the inclined surface, it causes inclined block 4 to move to the left. Clamp 5 is slidably connected to the inner wall of pad 1. The pad 1 has a slot corresponding to clamp 5, allowing clamp 5 to move left and right. Clamp 5 is clamped onto the inner wall of anchor 2. Anchor 2 has a slot corresponding to clamp 5.

[0019] Working principle: When it is necessary to connect and fix the anchor 2 and the pad 1, manually align the rectangular groove 8 on the anchor 2 with the positioning block 7, then manually move the anchor 2 downward so that the positioning block 7 is inserted into the groove of the rectangular groove 8, thus completing the horizontal limit of the anchor 2. Then manually tighten the bolt 6. When the bolt 6 contacts and presses the inclined surface of the inclined block 4, the four sets of inclined blocks 4 move closer to each other and the inclined blocks 4 will be locked into the groove of the anchor 2. When the anchor 2 and the pad 1 are fixed by the bolt 6, the connection and fixation between the pad 1 and the anchor 2 are further enhanced by the locking block 5.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
