Description

Technical Field

[0001] This utility model relates to the field of protection equipment technology, and in particular to a protection device for solving the problem of twisting of steel strands and tower platform legs in mixed towers. Background Technology

[0002] Wind power hybrid tower structures are increasingly widely used due to their comprehensive advantages. Their tower bodies are usually made of prestressed concrete structures, with multiple bundles of high-strength steel strands running through them to provide prestress. At the same time, the tower tube is equipped with multiple layers of steel platforms, and the supporting structure of these platforms, namely the torsion legs, extends into the internal space of the tower tube.

[0003] In actual operation, the tower will sway under wind load, and there may be slight deviations in construction and installation. This may cause continuous contact, friction or even collision between the steel strand bundle and the platform torsion leg. This can easily cause the anti-corrosion coating of the steel strand to be worn, thus exposing and damaging the steel wire itself, seriously threatening its long-term durability and the structural safety of the entire tower. In order to solve the above problems, this utility model provides a protective device for the steel strand of mixed towers and the torsion leg of the tower platform. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective device to solve the problem of twisting of the steel strands and tower platform legs in mixed towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A protective device for preventing twisting of steel strands in mixed towers and tower platforms includes a mounting base. A support frame is fixedly connected to the upper surface of the mounting base. A mounting frame is fixedly connected to the front of the support frame. A bidirectional threaded screw is rotatably connected to the inside of the mounting frame via a bearing. Lifting seats are threaded onto both ends of the surface of the bidirectional threaded screw. A U-shaped frame is fixedly connected to the front of each of the two lifting seats. A fixed annular anti-wear sleeve is fixedly connected to one side of the inside of the U-shaped frame, and a fixing component is provided on the other side of the inside of the U-shaped frame.

[0006] As a further improvement of this utility model, the fixing component includes a threaded hole opened on the other side inside the U-shaped frame. An adjusting bolt is threadedly connected inside the threaded hole. One end of the adjusting bolt is rotatably connected to a movable annular anti-wear sleeve through a bearing. A limit block is fixedly connected to one side of the movable annular anti-wear sleeve. The limit block is slidably connected to the upper end of the U-shaped frame.

[0007] As a further improvement of this utility model, a knob is fixedly connected to the other end of the adjusting bolt.

[0008] As a further improvement of this utility model, both the fixed annular anti-wear sleeve and the movable annular anti-wear sleeve are provided with anti-wear pads on their inner walls, and the anti-wear pads are made of rubber.

[0009] As a further improvement of this utility model, a mounting groove is provided at the lower end of the front side of the mounting frame, and a handle is provided inside the mounting groove. The handle is connected to a bidirectional threaded screw.

[0010] As a further improvement of this utility model, several through holes are provided on both sides of the mounting base, and mounting bolts are inserted into the interior of each of the through holes.

[0011] The beneficial effects of this utility model are: By setting up a fixed component, during use, turning the handle drives the bidirectional threaded screw to rotate, which can move the two lifting seats towards or away from each other, thereby adjusting the U-shaped frame to a suitable position. This facilitates the fixing of steel strands of different positions and specifications. At the same time, rotating the knob drives the adjusting bolt to screw in, which can push the movable annular anti-wear sleeve close to the fixed annular anti-wear sleeve, precisely clamping and fixing the steel strand. This flexible adjustment method allows the device to adapt to various actual working conditions, improving the device's versatility and practicality, and providing a reliable solution for the protection of steel strands in different scenarios.

[0012] By setting up annular anti-wear sleeves, both the fixed and movable annular anti-wear sleeves have rubber anti-wear pads on their inner walls during use. When the two sleeves together hold the steel strand tightly in place, the steel strand is encased in the protective space formed by the anti-wear pads. The rubber anti-wear pads have good flexibility and wear resistance, which can effectively buffer the friction between the steel strand and the device, prevent the steel strand from directly contacting the tower platform's torsional legs, thereby reducing the wear caused by friction on the steel strand, extending the service life of the steel strand, and ensuring the stability and safety of the hybrid tower structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-4 A protective device for preventing the twisting of steel strands in a mixed tower platform includes a mounting base 1. A support frame 2 is fixedly connected to the upper surface of the mounting base 1. A mounting frame 3 is fixedly connected to the front of the support frame 2. A bidirectional threaded screw 4 is rotatably connected to the inside of the mounting frame 3 via a bearing. Lifting seats 5 are threaded onto both ends of the surface of the bidirectional threaded screw 4. A U-shaped frame 6 is fixedly connected to the front of each of the two lifting seats 5. A fixed annular anti-wear sleeve 7 is fixedly connected to one side of the inside of the U-shaped frame 6. A fixing component is provided on the other side of the inside of the U-shaped frame 6.

[0020] In this utility model, the fixing component includes a threaded hole on the other side of the U-shaped frame 6. An adjusting bolt 8 is threadedly connected inside the threaded hole. The adjusting bolt 8 moves linearly through thread engagement, thereby providing power support for adjusting the position of the movable annular anti-wear sleeve 9. One end of the adjusting bolt 8 is rotatably connected to the movable annular anti-wear sleeve 9 through a bearing. The bearing connection ensures that the adjusting bolt 8 does not drive the movable annular anti-wear sleeve 9 to rotate synchronously when it rotates, but only pushes it to move linearly. A limit block 10 is fixedly connected to one side of the movable annular anti-wear sleeve 9. The limit block 10 is slidably connected to the upper end of the U-shaped frame 6. A knob 11 is fixedly connected to the other end of the adjusting bolt 8. The knob 11 provides an easy force application point for the operator to manually rotate the adjusting bolt 8 to adjust the position of the movable annular anti-wear sleeve 9.

[0021] Both the fixed annular anti-wear sleeve 7 and the movable annular anti-wear sleeve 9 are provided with anti-wear pads 12 on their inner walls. The anti-wear pads 12 are made of rubber, which has good flexibility and wear resistance, and can achieve flexible contact with the steel strand to reduce friction damage. The lower end of the front of the mounting frame 3 is provided with a mounting groove, and a handle 13 is provided inside the mounting groove. The handle 13 is connected to the bidirectional threaded screw 4. The handle 13 adopts a structure design that is easy to grip, so that the operator can manually drive the bidirectional threaded screw 4 to rotate.

[0022] The mounting base 1 has several through holes on both sides, which are symmetrically distributed. The appropriate through hole can be selected for fixing according to the actual needs of the installation position. The mounting bolts 14 are inserted into the through holes. The mounting bolts 14 are fitted with the through holes with clearance. The mounting base 1 is firmly fixed to the torsion leg of the tower platform by the tightening action of the bolts, ensuring the overall installation stability of the device.

[0023] In use, the mounting base 1 is fixed to the appropriate position of the torsion leg of the tower platform by mounting bolts 14. When it is necessary to protect the steel strand, the operator drives the bidirectional threaded screw 4 to rotate by turning the handle 13. The bidirectional threaded screw 4 drives the two lifting seats 5 on its surface to move towards or away from each other. The lifting seats 5 then drive the U-shaped frame 6 on them to move synchronously, thereby adjusting the two U-shaped frames 6 to a suitable position for fixing the steel strand. Subsequently, the operator rotates the knob 11, which drives the adjusting bolt 8 to screw into the threaded hole of the U-shaped frame 6 to adjust the position. Bolt 8 pushes the movable annular anti-wear sleeve 9 closer to the fixed annular anti-wear sleeve 7 until the fixed annular anti-wear sleeve 7 and the movable annular anti-wear sleeve 9 together clamp and fix the steel strand. During this process, the limiting block 10 plays a role in preventing the movable annular anti-wear sleeve 9 from rotating. Finally, the steel strand is wrapped in the protective space formed by the anti-wear pad 12 on the inner wall of the fixed annular anti-wear sleeve 7 and the movable annular anti-wear sleeve 9. The support frame 2 and the mounting frame 3 provide stable support for the entire clamping structure, thereby achieving effective protection of the steel strand and preventing it from rubbing and wearing against the torsional legs of the tower platform.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
