Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of work assistance platform technology, and more specifically, to a wind power hybrid tower inner cylinder installation work platform. Background Technology

[0002] The hybrid wind turbine tower is a hybrid tower that combines steel and concrete structures in wind turbine generator sets. The lower part uses precast concrete cylinders to provide stability, while the upper part connects to a steel tower to reduce the weight at the top. Its modular design facilitates transportation and on-site assembly, and can overcome the lifting height limitations of pure steel towers, enabling wind turbines to capture more wind energy in low wind speed areas. It is a new type of support structure solution that improves the economy and adaptability of wind power projects.

[0003] In the existing technology, when operators are installing the inner cylinder of a wind turbine tower, they often fix the installation platform to the inner wall of the cylinder for standing. However, although the existing installation platform has basic construction assistance functions, the diameter of the inner wall of the wind turbine tower becomes smaller as it goes higher. This requires operators to frequently change the installation platform during construction, which causes inconvenience to the operators. Therefore, improvements are needed. Utility Model Content

An insert rod is fixedly connected to the outer surface of each of the four hinge blocks. The outer end of the insert rod penetrates the surrounding plate and extends to the outer side of the surrounding plate. A cover plate is movably connected to the lower surface of the surrounding plate. A servo motor is fixedly installed on the lower surface of the cover plate. A circular shaft is fixedly sleeved at the other end of the output shaft of the servo motor. The top end of the outer surface of the circular shaft penetrates the cover plate and extends into the interior of the surrounding plate and is fixedly connected to a drive key. A cross plate is movably connected to the outer surface of both the circular shaft and the drive key. A connecting rod is hinged to the upper surface of the cross plate. The number of connecting rods is four. The other ends of the four connecting rods are respectively hinged to the lower surfaces of the four hinge blocks.

[0006] As a preferred technical solution of this disclosure, a connecting block is fixedly connected to the inner surface of the enclosure, and a bolt is movably sleeved on the lower surface of the cover plate. The top end of the bolt penetrates the cover plate and extends into the interior of the connecting block, and the outer surface of the bolt and the inner surface of the connecting block are threaded together.

[0007] As a preferred embodiment of this disclosure, the outer surfaces of the four hinge blocks are all fixedly connected to limit blocks, and the outer surfaces of the limit blocks are movably connected to the inner surfaces of the guide frame.

[0008] As a preferred technical solution of this disclosure, a protective shell is fixedly sleeved on the outer surface of the No. 1 servo motor, and the top of the protective shell is fixedly installed on the lower surface of the cover plate.

[0009] As a preferred embodiment of this disclosure, a fixing block is fixedly connected to the lower surface of the cover plate, and the number of fixing blocks is four, with the four fixing blocks having the same size.

[0010] As a preferred technical solution of this disclosure, a second servo motor is fixedly installed on the inner surface of each of the four fixed blocks, and a second round shaft is fixedly sleeved on the other end of the output shaft of the second servo motor.

[0011] As a preferred technical solution of this disclosure, a cam is fixedly sleeved on the outer surface of the second circular shaft, and a shaped plate is movably connected to the top of the outer surface of the cam. The upper surface of the shaped plate and the lower surface of the cover plate are movably connected.

[0012] As a preferred technical solution of this disclosure, a semicircular plate is movably connected to the upper surface of the first circular plate, and the number of the two semicircular plates is two, with the positions of the two semicircular plates being symmetrical about the front and back of the surrounding plate.

[0013] As a preferred technical solution of this disclosure, a fixing plate is fixedly connected to the upper surface of the first circular plate, and the outer surfaces of the front and rear sides of the fixing plate are movably connected to the semicircular plate. A second circular plate is fixedly connected to the upper surface of the fixing plate, and the lower surface of the second circular plate is movably connected to the upper surface of the semicircular plate.

[0014] As a preferred technical solution of this disclosure, a sleeve rod is fixedly connected to the upper surface of the irregular plate, and the top end of the sleeve rod passes through the cover plate, the first circular plate and the semi-circular plate in sequence and extends to the lower surface of the second circular plate.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: 1. This disclosure includes a hinge block, insert rods, drive key, cross plate, and connecting rod. When the operator starts the first servo motor, the first circular shaft, drive key, and cross plate will begin to rotate. The rotation of the cross plate will drive the connecting rod, causing the connecting rod to also rotate. At the same time, the other end of the connecting rod will drive the hinge block, causing the four hinge blocks to move in opposite directions. Finally, the four insert rods will be inserted into the inner wall of the wind turbine tower's inner cylinder. At this point, the entire enclosure will be fixed inside the wind turbine tower's inner cylinder, thus achieving the function of fixing the entire enclosure at different heights inside the wind turbine tower's inner cylinder.

[0016] 2. This disclosure incorporates a cam, a shaped plate, a connecting rod, a second circular plate, and a semi-circular plate. When the operator starts the second servo motor, the second circular shaft and the cam begin to rotate. The rotation of the cam drives the shaped plate, causing the shaped plate and the connecting rod to move up and down. When the shaped plate reaches its lowest point, the connecting rod moves below the semi-circular plate. At this point, the position of the semi-circular plate is no longer restricted by the connecting rod, allowing the operator to replace the semi-circular plate. Furthermore, by combining the second circular plate with semi-circular plates of different sizes, the overall standing area of ​​the second circular plate can be increased, thus facilitating the operator's work.

It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0020] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0025] like Figures 1-7 As shown, a wind power hybrid tower inner cylinder installation platform according to an embodiment of the present disclosure is provided, including a surrounding plate 1. A first circular plate 2 is fixedly connected to the upper surface of the surrounding plate 1. A guide frame 3 is fixedly connected to the lower surface of the first circular plate 2. A hinge block 4 is movably connected to the inner surface of the guide frame 3. There are four hinge blocks 4. Insert rods 5 are fixedly connected to the outer surfaces of the four hinge blocks 4. The outer ends of the insert rods 5 penetrate the surrounding plate 1 and extend to the outer side of the surrounding plate 1. A cover plate 6 is movably connected to the lower surface of the surrounding plate 1. A first servo motor 7 is fixedly installed on the lower surface of the cover plate 6. A first circular shaft 8 is fixedly sleeved at the other end of the output shaft of the first servo motor 7. The top end of the outer surface of the first circular shaft 8 penetrates the cover plate 6 and extends into the interior of the surrounding plate 1 and is fixedly connected to a drive key 9. A cross plate 10 is movably connected to the outer surfaces of the first circular shaft 8 and the drive key 9. Connecting rods 11 are hinged to the upper surface of the cross plate 10. There are four connecting rods 11. The other ends of the four connecting rods 11 are respectively hinged to the lower surfaces of the four hinge blocks 4.

[0026] The design of the first circular shaft 8 and the driving key 9 allows the first circular shaft 8 and the driving key 9 to be directly pulled out from the inside of the cross plate 10. At the same time, the rotation of the first circular shaft 8 and the driving key 9 will also drive the cross plate 10, thereby causing the cross plate 10 to rotate under the drive of the first circular shaft 8.

[0027] In some examples, a connecting block 13 is fixedly connected to the inner surface of the enclosure 1, and a bolt 14 is movably sleeved on the lower surface of the cover plate 6. The top end of the bolt 14 penetrates the cover plate 6 and extends into the interior of the connecting block 13. The outer surface of the bolt 14 and the inner surface of the connecting block 13 are threaded together.

[0028] The design of connecting block 13 and bolt 14 serves to fix the cover plate 6 as a whole under the whole enclosure plate 1.

[0029] In some examples, the outer surfaces of the four hinge blocks 4 are fixedly connected to limit blocks 12, and the outer surfaces of the limit blocks 12 are movably connected to the inner surfaces of the guide frame 3.

[0030] The design of the limiting block 12 serves to restrict the movement range of the hinge block 4.

[0031] In some examples, a protective shell 15 is fixedly fitted onto the outer surface of the first servo motor 7, and the top of the protective shell 15 is fixedly installed on the lower surface of the cover plate 6.

[0032] The protective shell 15 is designed to protect the No. 1 servo motor 7.

[0033] In some examples, the lower surface of the cover plate 6 is fixedly connected with four fixing blocks 16, all of which are the same size.

[0034] The length design of the fixing block 16 ensures that when the bottom end of the fixing block 16 touches the ground, the entire protective shell 15 will not touch the ground.

[0035] In some examples, a second servo motor 17 is fixedly mounted on the inner surface of each of the four fixed blocks 16, and a second round shaft 18 is fixedly sleeved at the other end of the output shaft of the second servo motor 17.

[0036] The second servo motor 17 has a self-locking function. When the second servo motor 17 stops, the second circular shaft 18 will not rotate under the action of external force.

[0037] In some examples, a cam 19 is fixedly sleeved on the outer surface of the second circular shaft 18, and a shaped plate 20 is movably connected to the top of the outer surface of the cam 19. The upper surface of the shaped plate 20 and the lower surface of the cover plate 6 are movably connected.

[0038] The shape of the irregular plate 20 will not affect the operator's ability to disassemble the bolt 14.

[0039] In some examples, the upper surface of circular plate 2 is movably connected to a semicircular plate 24, and there are two semicircular plates 24. The positions of the two semicircular plates 24 are symmetrical about the front and back of the surrounding plate 1.

[0040] The design of the semi-circular plate 24 can expand the overall standing area of ​​the enclosure 1, thereby providing convenience for the operators during construction.

[0041] In some examples, a fixing plate 22 is fixedly connected to the upper surface of the first circular plate 2, and the outer surfaces of the front and rear sides of the fixing plate 22 are movably connected to the semi-circular plate 24. A second circular plate 23 is fixedly connected to the upper surface of the fixing plate 22, and the lower surface of the second circular plate 23 is movably connected to the upper surface of the semi-circular plate 24.

[0042] The design of the fixed plate 22 makes it easy for operators to assemble the semi-circular plate 24.

[0043] In some examples, a sleeve rod 21 is fixedly connected to the upper surface of the irregular plate 20. The top end of the sleeve rod 21 passes through the cover plate 6, the first circular plate 2 and the semi-circular plate 24 in sequence and extends to the lower surface of the second circular plate 23.

[0044] The design of the connecting rod 21 serves to restrict the position of the semicircular plate 24.

[0045] The working principle and usage process of this disclosure are as follows: First, the operator starts the second servo motor 17. As the second servo motor 17 runs, the second circular shaft 18 and cam 19 begin to rotate. The rotation of cam 19 drives the irregular plate 20, causing the irregular plate 20 and the connecting rod 21 to move. When cam 19 rotates 90 degrees, the irregular plate 20 and the connecting rod 21 are at their lowest point. At this time, the connecting rod 21 slides down below the semicircular plate 24, which releases the restriction on the semicircular plate 24. The operator can then remove the original semicircular plate 24 and select a semicircular plate 24 of the appropriate size for construction needs for reassembly. After the new semicircular plate 24 is assembled, the operator starts the second servo motor 17 to reset the irregular plate 20 and the connecting rod 21 as a whole, thus completing the installation of the new semicircular plate 24.

[0046] Then, the operator hoists the entire enclosure 1 to the predetermined height. The operator then starts the first servo motor 7. As the first servo motor 7 runs, the first circular shaft 8, the drive key 9, and the cross plate 10 will begin to rotate. The rotation of the cross plate 10 will cause the four connecting rods 11 to rotate as well. The four hinge blocks 4 will then move in opposite directions under the drive of the four connecting rods 11. Finally, the insertion rod 5 will be inserted into the inner wall of the wind turbine tower's inner cylinder. This will fix the second circular plate 23 and the semi-circular plate 24 in the inner cylinder of the wind turbine tower, facilitating the operator's subsequent construction.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
