Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower-related products, specifically a transport support structure for a wind power generation concrete tower. Background Technology

[0002] As an important component of wind turbine generator sets, the wind turbine tower is a structure that supports the wind turbine blades, rotor, and generator. Concrete wind turbine towers are assembled from a large number of precast concrete components to form a cylindrical structure of the required specifications for the wind power project, which is then anchored to the foundation to support the entire wind turbine unit.

[0003] Currently, during the transportation of wind turbine towers, workers often bind and lock them to further limit and fix them. However, this method is not very stable and is prone to shaking. In severe cases, it may even detach from the support base. Moreover, the operation is cumbersome, time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a transport support structure for concrete towers used in wind power generation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transport support structure for a wind power generation concrete tower, comprising a support base, two bearing seats fixedly connected to the top of the support base, upright plates fixedly connected to the top of each of the two bearing seats, a cover plate installed between the top ends of the two upright plates, a fixing block fixedly connected to the cover plate, a screw hole provided on the fixing block, a threaded rod threaded into the screw hole, a movable plate rotatably connected to the bottom end of the threaded rod, two pressure plates fixedly connected to the bottom of the movable plate, a connecting plate fixedly connected to the top end of the threaded rod, a handwheel fixedly connected to the connecting plate, a limiting rod slidably inserted into one end of the connecting plate, and multiple limiting grooves corresponding to the limiting rod provided on the cover plate.

[0006] Preferably, one end of the cover plate is hinged to one of the upright plates via multiple hinges, and a positioning plate is fixedly connected to the bottom of the other end of the cover plate. A locking bolt is inserted into the positioning plate, and a threaded groove corresponding to the locking bolt is provided on the outer wall of the upright plate.

[0007] Preferably, an anti-detachment block is fixedly connected to the limiting rod, and a spring is sleeved on the limiting rod, with both ends of the spring fixedly connected to the anti-detachment block and the connecting plate, respectively.

[0008] Preferably, a stabilizing rod is fixedly connected to the top of both ends of the movable plate, and the stabilizing rod is slidably inserted into the cover plate.

[0009] Preferably, both the bearing seat and the pressure plate are provided with arc-shaped grooves, and a rubber plate is fixedly connected in the arc-shaped groove of the pressure plate.

[0010] Preferably, the multiple limiting grooves on the cover plate are equidistant.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The transport support structure for this wind power concrete tower consists of two components, located at both ends of the tower. The tower ends are supported by bearing seats on the top of the support base. A cover plate is then fixed, and a limiting rod is pulled upwards from the limiting groove on the cover plate. The connecting disc is rotated, assisted by a handwheel. At this time, the threaded rod rotates within the threaded hole on the fixing block, simultaneously pushing the moving plate downwards. The pressure plate at the bottom of the moving plate then presses down to fix the tower. After fixing, the limiting rod is inserted into the corresponding limiting groove to fix the position of the moving plate. This invention, through the setting of the pressing and fixing components, further locks both ends of the wind power tower, making it less likely for the wind power tower to deviate from its track and improving the stability of the wind power tower during transportation.

[0019] Please see Figure 1-2 This utility model provides an embodiment of a transport support structure for a wind power generation concrete tower, including a support base 1. Two bearing seats 2 are fixedly connected to the top of the support base 1. Each bearing seat 2 has a vertical plate 3 fixedly connected to its top. A cover plate 4 is installed between the tops of the two vertical plates 3. A fixing block 5 is fixedly connected to the cover plate 4. The fixing block 5 has a screw hole, and a threaded rod 6 is threaded into the screw hole. A movable plate 7 is rotatably connected to the bottom of the threaded rod 6. Two pressure plates 8 are fixedly connected to the bottom of the movable plate 7. A connecting disc 9 is fixedly connected to the top of the threaded rod 6. A handwheel 10 is fixedly connected to the connecting disc 9. One end of the support is slidably inserted with a limiting rod 11. The cover plate 4 is provided with multiple limiting grooves corresponding to the limiting rod 11. Specifically, the bearing seat 2 on the top of the support seat 1 supports the end of the tower. Then the cover plate 4 is fixed. By pulling the limiting rod 11 upward, it is pulled out from the limiting groove on the cover plate 4. The connecting plate 9 is rotated, and the handwheel 10 is used to assist in the rotation. At this time, the threaded rod 6 will rotate in the screw hole on the fixing block 5. At the same time, the threaded rod 6 will push the moving plate 7 to move down. At this time, the pressure plate 8 on the bottom of the moving plate 7 presses down to fix the tower. After the fixation is completed, the limiting rod 11 is inserted into the corresponding limiting groove to fix the position of the moving plate 7.

[0020] In this embodiment, one end of the cover plate 4 is hinged to one of the upright plates 3 via multiple hinges 12. A positioning plate 13 is fixedly connected to the bottom of the other end of the cover plate 4. A locking bolt 14 is inserted into the positioning plate 13. A threaded groove corresponding to the locking bolt 14 is provided on the outer wall of the upright plate 3. The hinges 12 facilitate the opening and closing of the cover plate 4 to accommodate different tower placement positions. The locking bolt 14 is used to fix the positioning plate 13 and secure the cover plate 4. An anti-detachment block 15 is fixedly connected to the limiting rod 11, and a spring 16 is sleeved on the limiting rod 11. The two ends of the spring 16 are respectively connected to the anti-detachment block 15 and the connecting rod 16. The receiving plate 9 is fixedly connected, and the spring 16 ensures that the limiting rod 11 is securely engaged inside the limiting groove. The top of both ends of the moving plate 7 are fixedly connected to the stabilizing rod 17, which slides onto the cover plate 4 to limit the two ends of the moving plate 7 and prevent it from rotating with the threaded rod 6. Both the bearing seat 2 and the pressure plate 8 are provided with arc-shaped grooves. A rubber plate 18 is fixedly connected in the arc-shaped groove on the pressure plate 8. The arc-shaped groove fits the outer wall of the tower better, and the rubber plate 18 increases friction while improving the buffering force. The multiple limiting grooves on the cover plate 4 are equidistantly arranged.

[0021] Working principle: First, the bearing seat 2 on the top of the support seat 1 supports the end of the tower. Then, the cover plate 4 is fixed. The limiting rod 11 is pulled out from the limiting groove on the cover plate 4 by pulling it upward. The connecting plate 9 is rotated, and the handwheel 10 is used to assist in the rotation. At this time, the threaded rod 6 will rotate in the screw hole on the fixing block 5. At the same time, the threaded rod 6 will push the moving plate 7 to move down. At this time, the pressure plate 8 on the bottom of the moving plate 7 presses down to fix the tower. After the fixation is completed, the limiting rod 11 is inserted into the corresponding limiting groove to fix the position of the moving plate 7.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
