Description

Technical Field

[0001] This utility model relates to the field of wind power transportation equipment technology, and in particular to a quick fixing device for wind turbine towers. Background Technology

[0002] A wind turbine tower is the support structure for wind power generation. The transportation equipment for wind turbine towers mostly consists of limiting devices and ropes. During the fixing process, the limiting devices need to be adjusted multiple times, and finally the ropes are used for binding. This results in complex operation and long installation time.

[0003] The prior art discloses a wind turbine tower transportation and fixing device with the publication number CN218199917U, which includes a base and a pair of clamps rotatably mounted on the base. The base includes a bottom plate, a pair of upright plates located above the bottom plate, and a fixing plate connecting the two upright plates. The rotation control shaft drives the pin shaft to rotate, thereby clamping the wind turbine tower. The operation is simple and the clamping method is firm.

[0004] However, when using it, it is still necessary to rotate the turntable with a needle to bring the two clamps closer together and clamp and fix the wind turbine tower, which is not convenient to use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of using a needle to rotate a turntable to bring two clamps closer together and clamp the wind turbine tower. Therefore, this invention proposes a rapid fixing device for wind turbine towers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a quick fixing device for wind turbine towers, including a base plate, on the top of which a pair of clamping plates for clamping the wind turbine towers are mounted via a rotating mounting assembly, and a pressure plate is fixedly connected to the lower end of the pair of clamping plates on the side close to each other, and the pressure plate is used to support the wind turbine towers.

[0008] A positioning component is provided on the outer side of the pair of clamping plates, and the positioning component is used to position the clamping plates.

[0009] Furthermore, the positioning assembly includes a hydraulic cylinder rotatably mounted on the base plate and an oil tank fixedly mounted on the base plate. The oil tank has valves installed at its inlet and outlet, and the other end of the valves is connected to the hydraulic cylinder through a pipe. The upper end of the hydraulic cylinder is rotatably connected to a clamping plate.

[0010] Furthermore, a triangular pressure block is integrally formed on the end faces of the pair of clamping plates close to each other, and the inclined surface of the triangular pressure block abuts against the wind turbine tower.

[0011] Furthermore, each of the pair of pressure plates has a downwardly curved arc plate fixedly connected to one end of each other.

[0012] Furthermore, the rotating mounting assembly includes a pair of bearing seats fixed to the top of the base plate, and a rotating shaft is rotatably mounted between the pair of bearing seats. A clamping plate is fixedly connected to the outer wall of the rotating shaft, and a reset assembly is installed at the front end of the rotating shaft through the bearing seats.

[0013] Furthermore, the reset assembly includes a turntable fixed to the front end of the rotating shaft and a torsion spring sleeved on the rotating shaft, with the front and rear ends of the torsion spring respectively fixedly connected to the turntable and the bearing seat.

[0014] The present invention proposes a quick fixing device for wind turbine towers, which has the following advantages: by setting a clamping plate that can rotate around a pivot and a pressure plate on the inner bottom of the clamping plate, the pressure plate can be pressed down and the clamping plate can be driven to clamp and fix the wind turbine tower as the wind turbine tower descends. The clamping plate can be automatically driven to rotate and clamp and fix the wind turbine tower without operation, making it more convenient and faster to use. At the same time, the pressure of the wind turbine tower itself on the pressure plate can be converted into a driving force to drive the clamping plate to rotate inward, and further converted into a clamping force on the wind turbine tower.

[0020] 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.

[0021] Reference Figure 1-4As an embodiment of this utility model, a quick fixing device for wind turbine tower is disclosed, including a base plate 1. A pair of clamping plates 4 for clamping wind turbine tower 3 are installed on the top of the base plate 1 through a rotating mounting assembly 2. A pressure plate 5 is fixedly connected to the lower end of the pair of clamping plates 4 on the side close to each other, and the pressure plate 5 is used to support the wind turbine tower 3.

[0022] A positioning component 6 is provided on the outer side of the pair of clamping plates 4, and the positioning component 6 is used to position the clamping plates 4.

[0023] During descent, the pressure plate 5 will press down and drive the clamping plate 4 to rotate and approach, thereby clamping and fixing the wind turbine tower 3 through the approaching clamping plate 4, and preventing the clamping plate 4 from rotating and supporting after clamping the wind turbine tower 3 through the positioning component 6.

[0024] It should be noted that the positioning component 6 includes a hydraulic cylinder 61 rotatably mounted on the base plate 1 and an oil tank 62 fixedly mounted on the base plate 1. The oil tank 62 has valves 63 installed at its inlet and outlet, and the other end of the valves 63 is connected to the hydraulic cylinder 61 through a pipe. The upper end of the hydraulic cylinder 61 is rotatably connected to the clamping plate 4.

[0025] Opening valve 63 allows the hydraulic oil in hydraulic cylinder 61 to freely enter and exit oil tank 62 through pipes and valve 63, thereby allowing hydraulic cylinder 61 to freely extend and retract as clamping plate 4 rotates;

[0026] Closing valve 63 prevents hydraulic oil in hydraulic cylinder 61 from entering or leaving oil tank 62, thus preventing hydraulic cylinder 61 from extending or retracting. Consequently, the length of hydraulic cylinder 61 remains unchanged, and the clamping plate 4 is supported and positioned by hydraulic cylinder 61 with unchanged length.

[0027] Specifically, a triangular pressure block 7 is integrally formed on the end faces of the pair of clamping plates 4 near each other, and the inclined surface of the triangular pressure block 7 abuts against the wind turbine tower 3.

[0028] The triangular pressure block 7 clamps the wind turbine tower 3 while preventing it from moving upward, thus preventing the wind turbine tower 3 from vibrating.

[0029] In some embodiments, a downwardly curved arc plate 8 is fixedly connected to one end of each pair of pressure plates 5 near each other;

[0030] When the wind turbine tower 3 descends, it first comes into contact with the arc plate 8. As the arc plate 8 continues to descend, the arc plate 8 slides relative to the wind turbine tower 3, thereby raising the arc plate 8 to prevent it from being stuck when the wind turbine tower 3 descends and presses down on the pressure plate 5.

[0031] Furthermore, the rotating mounting assembly 2 includes a pair of bearing seats 21 fixed to the top of the base plate 1, and a rotating shaft 22 is rotatably mounted between the pair of bearing seats 21. The outer wall of the rotating shaft 22 is fixedly connected to the clamping plate 4, and the front end of the rotating shaft 22 passes through the bearing seat 21 and is equipped with a reset assembly 23.

[0032] Furthermore, the reset assembly 23 includes a turntable 231 fixed to the front end of the rotating shaft 22 and a torsion spring 232 sleeved on the rotating shaft 22. The front and rear ends of the torsion spring 232 are respectively fixedly connected to the turntable 231 and the bearing seat 21.

[0033] When the wind turbine tower 3 is removed, the turntable 231 rotates under the action of the torsion spring 232 and drives the rotating shaft 22 to rotate, thereby causing the clamping plate 4 and the pressure plate 5 to rotate and reset. The clamping plate 4 rotates outward to allow the wind turbine tower 3 to descend next time, and the pressure plate 5 rotates upward to be pressed down by the wind turbine tower 3 next time.

[0034] Working method: When fixing, open valve 63, place the wind turbine tower 3 on the arc plate 8 on the top of the two pressure plates 5 and press down to make the two pressure plates 5 rotate. At the same time, the clamping plate 4 rotates upward and inward until it is blocked by the wind turbine tower 3. The wind turbine tower 3 is clamped by a pair of clamping plates 4 and lifted by the pressure plates 5. The wind turbine tower 3 is fixed in conjunction with the triangular pressure block 7.

[0035] Then close valve 63 to prevent hydraulic cylinder 61 from extending or retracting, and support and position clamping plate 4 through hydraulic cylinder 61 of constant length.

[0036] 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.
