Description

Technical Field

[0001] This utility model relates to the field of wind turbine transportation technology, specifically a high-stability wind turbine transportation-specific fixing screw. Background Technology

[0002] When transporting wind turbines, the turbine legs are typically secured to the transport frame using bolts. However, most existing bolts are one-way, making it difficult to guarantee they won't loosen under vibration, thus affecting the turbine's fixation. Therefore, designing a highly stable, dedicated wind turbine transport fixing screw is crucial. For example:

[0003] A cylindrical fixing screw, authorized by publication number CN216742372U, belongs to the field of hardware technology and specifically relates to a cylindrical fixing screw, including a limiting body, a screw body, a nut, a connecting rod, and a connecting head. The bottom of the limiting body and the top of the connecting head are respectively fixedly connected to the two ends of the connecting rod. The connecting head is a disc-shaped part with a notch, the notch being cut from top to bottom to form an arc-shaped surface protruding outward from the vertical axis of symmetry. The nut is fixedly installed at the bottom of the screw body. The top of the screw body has an installation port with an opening radius smaller than that of the connecting head, and the screw body has a cylindrical inner cavity that communicates with the installation port. The radius of the inner cavity is larger than that of the installation port. A groove with an arc-shaped cross-section is provided at the central axis position of the top plane of the limiting body, and the groove connects the two ends of the top plane of the limiting body. Through the above-mentioned design, the contact surface between the fixing screw and the cylindrical body is increased, thereby increasing friction during fixing and preventing the cylindrical body from easily sliding off.

[0004] Based on existing solutions and actual production and processing, the existing special fixing screws for wind turbine transportation have the following defects, such as:

[0005] While existing wind turbine transport fixing screws can increase the contact area between the fixing screw and the column, the connection stability is not high, posing a potential risk to the fixed connection of the wind turbine. Therefore, this utility model provides a high-stability wind turbine transport fixing screw to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a high-stability fixed screw for transporting wind turbines, in order to solve the problem mentioned in the background art that although the existing fixed screws for transporting wind turbines can increase the contact surface between the fixed screw and the column, the connection stability is not high, and there are hidden dangers in the fixed connection of the wind turbine.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-stability fan transport-specific fixing screw, comprising a threaded rod, wherein the upper outer end of the threaded rod is provided with a first threaded groove, and the lower outer end of the threaded rod is provided with a second threaded groove, and a drive plate is provided on the upper side of the threaded rod;

[0008] A protective edge is provided on the outside of the drive plate, and a limit structure is provided inside the drive plate. A connecting seat is provided on the lower outer side of the threaded rod, and a locking plate is provided on the upper end of the connecting seat. A positioning rod is connected to the inner side of the connecting seat, and a protective cover is provided on the outer side of the positioning rod.

[0012] Preferably, the protective cover has a "T" shaped structure and is arranged symmetrically about the center line of the connecting seat.

[0013] Preferably, the connecting seat has an annular structure, and the threaded rod passes through the interior of the connecting seat, and the diameter of the connecting seat is larger than the diameter of the threaded rod.

[0014] Preferably, the connecting seat is perpendicular to the fixing plate, and a trapezoidal reinforcing plate is installed at the lower end of the fixing plate, and the reinforcing plate is set at an equal angle with respect to the center of the fixing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the high-stability fan transport special fixing screw improves the stability of the fan transport special fixing screw by reversing the thread of the fan transport special fixing screw, and at the same time, the fan transport special fixing screw is limited by the installation, which strengthens the firmness of the connection of the fan transport special fixing screw.

[0017] 2. It is equipped with a connecting seat and a fixing plate. By aligning the hole inside the fixing plate with the lower end of the threaded rod and rotating it, the connecting seat is threadedly connected to the second thread groove. The first thread groove and the second thread groove are set in opposite directions, making it difficult for the threaded rod to loosen after connection, which helps to improve the stability of the fan transportation special fixing screw during connection.

[0018] 3. Equipped with protective covers and reinforcing plates, the positioning rod is pushed after being aligned with the positioning hole inside the threaded rod. The protective covers are then screwed onto the outside of the two sets of third threaded grooves on the left and right sides.

[0025] 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.

[0026] Please see Figure 1-5This utility model provides a technical solution: a high-stability fan transport-specific fixing screw, including a threaded rod 1, a first threaded groove 2, a second threaded groove 3, a drive plate 4, a limiting groove 5, a protective edge 6, a positioning hole 7, a positioning rod 8, a third threaded groove 9, a protective cover 10, a connecting hole 11, a connecting seat 12, a reinforcing plate 13, a clamping plate 14, a support plate frame 15, a mounting hole 16, a fan connecting foot 17, and a bolt hole 18.

[0027] Specific examples Figure 1 and Figure 2 As shown, first, place the support plate frame 15 horizontally. After placing the support plate frame 15, place the fan connector 17 parallel to the support plate frame 15, with the lower end of the fan connector 17 contacting the upper end of the support plate frame 15. The fan connector 17 has a bolt hole 18 inside, and the support plate frame 15 has a mounting hole 16 inside. Align the bolt hole 18 with the mounting hole 16 so that they are on the same longitudinal axis. After aligning the lower end of the threaded rod 1 with the upper end of the bolt hole 18, engage the Phillips screwdriver in the limiting groove 5 inside the drive plate 4. The drive plate 4 has a protective edge 6 on its outer side for protection. After rotating the Phillips screwdriver, the drive plate 4 follows the screwdriver... As the drive plate 4 rotates, a threaded rod 1 is vertically installed at the lower end. The threaded rod 1 aligns with the bolt hole 18 inside the fan mount 17 and moves downward. When the second threaded groove 3 at the lower outer end of the threaded rod 1 passes through the bolt hole 18 and the mounting hole 16 in sequence, the Phillips screwdriver is rotated in the opposite direction. At this time, the first threaded groove 2 at the upper outer end of the threaded rod 1 contacts the bolt hole 18 and the mounting hole 16 in sequence. During the movement of the threaded rod 1 following the drive plate 4, the threaded rod 1 generates sliding friction with the fan mount 17 and the support plate frame 15. The second threaded groove 3 and the first threaded groove 2 are threadedly connected to the fan mount 17 and the support plate frame 15, which facilitates the limiting and fixing function of the fan transportation special fixing screw.

[0028] Specific examples Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, when the bottom end of the drive plate 4 contacts the upper end of the fan connector 17, the lower end of the fan connector 17 contacts the upper end of the support plate frame 15, and the second threaded groove 3 provided on the lower outer side of the threaded rod 1 extends downward from the inside of the mounting hole 16. After aligning the hole inside the coupling plate 14 with the lower end of the threaded rod 1, it is rotated. The lower end of the coupling plate 14 is provided with a connecting seat 12 with a circular structure. After the coupling plate 14 is aligned with the lower end of the threaded rod 1 and rotated, the connecting seat 12 and the second threaded groove 3 provided on the lower outer end of the threaded rod 1 engage. The threaded connection continues until the top of the mounting plate 14 contacts the bottom of the support plate frame 15, so that the threaded rod 1 secures the fan connector 17 to the support plate frame 15. The upper outer end of the threaded rod 1 is connected to the support plate frame 15 and the fan connector 17 through the first threaded groove 2, and the lower outer end of the threaded rod 1 is connected to the connecting seat 12 and the mounting plate 14 through the second threaded groove 3. The first threaded groove 2 and the second threaded groove 3 are set in opposite directions, making it difficult for the threaded rod 1 to loosen after connection, which facilitates the stability of the fan transport special fixing screw during connection.

[0029] Specific examples Figure 1 , Figure 4 and Figure 5 As shown, a reinforcing plate 13 is provided at the lower end of the fixing plate 14. The reinforcing plate 13 has a trapezoidal structure. The upper end of the reinforcing plate 13 contacts the lower end of the fixing plate 14, and the inner end of the reinforcing plate 13 contacts the outer end of the connecting seat 12. The reinforcing plate 13 is set at an equal angle about the center of the fixing plate 14. Under the action of the reinforcing plate 13, the connection between the connecting seat 12 and the fixing plate 14 is reinforced. At the same time, the positioning rod 8 is placed horizontally and aligned with the positioning hole 7 opened inside the threaded rod 1 before proceeding. The positioning rod 8 is pushed through the connection between the connecting seat 12 and the threaded rod 1. The positioning rod 8 has a third threaded groove 9 at both ends. The protective cover 10 is screwed on the outside of the two sets of third threaded grooves 9, so that the connecting hole 11 inside the protective cover 10 covers the third threaded groove 9. The positioning rod 8 is protected by the protective cover 10, which facilitates the reinforcement and protection of the special fixing screw for wind turbine transportation. This is the usage method of the high-stability special fixing screw for wind turbine transportation.
