Description

Technical Field

[0001] This utility model belongs to the field of wind turbine tower prefabrication technology, and in particular relates to wind turbine tower embedded part clamps. Background Technology

[0002] A wind turbine tower is the support structure for wind power generation. It plays a supporting role in wind turbine generator sets and also absorbs vibrations from the generator set. Wind turbine towers commonly use either all-steel towers or precast concrete towers. Precast concrete towers are mostly assembled in sections or pieces. Sectional assembly means that each section of the concrete tower is assembled from multiple precast concrete components. Each concrete component is lightweight and small in size, making it easy to transport. During the prefabrication process, wind turbine tower sections often require the pre-embedding of multiple components, including hanging nails, positioning holes, pre-embedded anchor plates, pre-embedded steel pipes, flipping components, ladder support components, grounding components, construction platform support components, safety anchor point components, permanent platform support components, guide device components, tower door components, switch and socket installation components, camera installation components, cable tray installation components, external ladder installation components, elevator beam support components, cable twisting bracket support components, and installation ladder support components. The number of pre-embedded components in a single section can reach 37.

[0003] When using vertical casting technology for tower segment prefabrication, the space for opening the side formwork is limited. In addition, with the placement of the steel reinforcement frame, the installation space is narrow, and multiple embedded parts need to be installed, which is time-consuming and labor-intensive. Therefore, a wind turbine tower segment embedded part clamp is needed. Multiple embedded parts can be installed on the positioning base first, and then the clamp can be used to clamp and fix the multiple embedded parts to facilitate the movement of the embedded parts during subsequent processing. Moreover, the adjustable structure of the clamp can adapt to the needs of clamping and moving embedded parts of different sizes, thereby improving the applicability of the clamp structure. Utility Model Content

[0004] The purpose of this utility model is to provide a clamp for embedded parts of wind turbine tower sections. It has the advantages of first installing multiple embedded parts onto a positioning base, and then clamping and fixing the multiple embedded parts with a clamp, so as to facilitate the position movement of the embedded parts during subsequent processing. Furthermore, the adjustable structure of the clamp can adapt to the needs of clamping and moving embedded parts of different sizes, thereby improving the applicability of the clamp structure and solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A wind turbine tower embedded component clamp includes two arc-shaped steel plates: an inner steel pipe is fixedly installed on the top of the upper arc-shaped steel plate, and an outer threaded arc-shaped plate is fixedly connected to the top of the lower arc-shaped steel plate. The top of the outer threaded arc-shaped plate extends through to the top of the upper arc-shaped steel plate. An internal threaded sleeve is rotatably connected to the surface of the inner steel pipe. A rectangular panel is fixedly connected to the surface of the arc-shaped steel plate.

[0012] The wind turbine tower embedded part clamp described above is further provided in this utility model: a nut block is welded to the end of the threaded rod.

[0013] The beneficial effects of this utility model are:

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. Example

[0029] Figure 1-4This invention illustrates a wind turbine tower embedded component clamp according to an embodiment of the present invention, comprising two arc-shaped steel plates 1: an inner steel pipe 2 is fixedly installed on the top of the upper arc-shaped steel plate 1, and an outer threaded arc-shaped plate 3 is fixedly connected to the top of the lower arc-shaped steel plate 1.

A steel lifting ring 5 is welded to the top of the inner steel pipe 2. The steel lifting ring 5 facilitates the application of force to the inner steel pipe 2, thereby facilitating the subsequent movement of the clamp structure and improving the operability of moving the clamp structure. The surface of the arc-shaped steel plate 1... A rectangular panel 6 is fixedly connected. A gear 7 and a connecting rod 8 are rotatably connected to the surface of the rectangular panel 6. A clamping rod 9 is rotatably connected between the connecting rod 8 and the gear 7 via a rotating shaft. A wedge-shaped clamping block 10 is integrally formed on the surface of the clamping rod 9. A rack 12 is provided on the outer side of the rectangular panel 6. An internally threaded tube 13 is welded to one end of the rack 12. A threaded rod 14 is threadedly connected to the inner wall of the internally threaded tube 13. The end of the threaded rod 14 extends to the outer side of the arc-shaped steel plate 1. A rectangular slider 16 is integrally formed on the surface of the internally threaded tube 13. A slider groove 17 is opened on the surface of the rectangular panel 6. The rectangular slider 16 is slidably connected to the inner wall of the slider groove 17. A tower plate embedded part is provided between the two arc-shaped steel plates 1.

[0030] In a preferred embodiment of a wind turbine tower embedded part clamp, two arc-shaped steel plates 1 are a first arc-shaped steel plate and a second arc-shaped panel, respectively. An inner steel pipe is fixedly installed on the top of the first arc-shaped steel plate, and an outer threaded arc-shaped plate is fixedly connected to the top of the second arc-shaped panel; a rectangular panel 6 is fixedly connected to the surface of either the first arc-shaped steel plate or the second arc-shaped panel.

Rectangular panels 6 with corresponding positions are fixedly connected to the surfaces of the first curved steel plate and the second curved panel, respectively.

Example

[0032] Figure 1-4 This invention illustrates a wind turbine tower section embedded part clamp according to an embodiment of the present invention, which includes two arc-shaped steel plates 1: as shown Figure 1 As shown, located Figure 1An inner steel pipe 2 is fixedly installed on the top of the upper curved steel plate 1, located at... Figure 1 An outer threaded arc plate 3 is fixedly connected to the top of the lower arc-shaped steel plate 1. The top of the outer threaded arc plate 3 extends through to the top of the upper arc-shaped steel plate 1. The arc-shaped steel plate 1 has corresponding openings for the outer threaded arc plate. The curvature of the outer threaded arc plate 3 is preferably 200 degrees to 300 degrees. An inner threaded sleeve 4 is rotatably connected to the surface of the inner steel pipe 2. For example, the inner threaded sleeve is connected to the inner steel pipe via a bearing. The cross-section of the inner threaded sleeve is as follows: Figure 1 The concave structure shown in this utility model requires attention. Figure 1 The internal threaded sleeve shown is relatively short. The length of the internal threaded sleeve should be adapted to the needs of adjusting the distance between the two arc-shaped steel plates, such as 10 cm to 20 cm. The external threaded arc plate 3 of this utility model passes through the opening of the arc-shaped steel plate 1 and can be adjusted in position as the internal threaded sleeve 4 rotates.

[0033] A rectangular panel 6 is fixedly connected to the surface of the curved steel plate 1. A gear 7 and a connecting rod 8 are rotatably connected to the surface of the rectangular panel 6.

By setting the protective pad 11, the surface of the wedge-shaped clamping block 10 is protected, avoiding the situation where the surface of the embedded part is squeezed and damaged when the wedge-shaped clamping block 10 directly contacts the embedded part, thus improving the protection of the embedded part. A rack 12 is provided on the outer side of the rectangular panel 6. One end of the rack 12 is welded with an internally threaded tube 13. The inner wall of the internally threaded tube 13 is threaded with a threaded rod 14. The end of the threaded rod 14 extends to the outer side of the arc-shaped steel plate 1. Preferably, the threaded rod is connected to the arc-shaped steel plate through a bearing. A nut block 15 is welded to the end of the threaded rod 14. The nut block 15 facilitates the application of force to the threaded rod 14 and avoids the slippage that occurs when directly rotating the threaded rod 14, thus improving the convenience of operation. A rectangular slider 16 is integrally formed on the surface of the internally threaded tube 13, and a slider groove 17 is opened on the surface of the rectangular panel 6.

[0034] This utility model also provides a method for using a wind turbine tower embedded part clamp. The user sets up a precise positioning platform for the embedded parts on the ground. The positioning platform has raised rubber positioning bases at the corresponding embedded part positions. First, multiple embedded parts are installed onto the positioning bases. Then, the internal threaded sleeve 4 is rotated to tighten the inner steel pipe 2 and the outer threaded arc plate 3, thereby bringing the two arc-shaped steel plates 1 together. Next, the threaded rod 14 is rotated to move the internal threaded tube 13. During this process, the movement of the internal threaded tube 13 is limited by the cooperation of the rectangular slider 16 and the slider groove 17, ensuring the internal threaded tube 13 is properly positioned. The stability of the threaded tube 13 during movement allows the internal threaded tube 13 to drive the gear 7 to rotate via the rack 12. At this time, under the limiting action of the connecting rod 8, the gear 7 drives the wedge-shaped clamping block 10 to clamp the embedded part via the clamping rod 9. The position of the corresponding threaded rod is adjusted for each embedded part with different structure and position, so as to clamp and fix multiple embedded parts with the fixture, so as to facilitate the position movement of the embedded parts during subsequent processing. Moreover, the adjustable fixture structure can adapt to the needs of clamping and moving embedded parts of different sizes, thereby improving the applicability of the fixture structure.

[0035] In summary, this wind turbine tower embedded part clamp tightens the inner steel pipe 2 and the outer threaded arc plate 3 by rotating the inner threaded sleeve 4, thereby bringing the two arc-shaped steel plates 1 together. Then, rotating the threaded rod 14 drives the inner threaded tube 13 to move, so that the inner threaded tube 13 drives the gear 7 to rotate through the rack 12. At this time, under the limiting action of the connecting rod 8, the gear 7 drives the clamping rod 9 to clamp the embedded part. This achieves the purpose of clamping and fixing multiple embedded parts through the clamp, so as to facilitate the position movement of the embedded parts during subsequent processing. Moreover, the adjustable structure of the clamp can adapt to the needs of clamping and moving embedded parts of different sizes, thereby improving the applicability of the clamp structure.
