Description

Technical Field

[0001] This utility model relates to the field of cable equipment technology, specifically to a wind turbine generator power cable lifting device. Background Technology

[0002] As core equipment in the clean energy sector, wind turbine generators are typically installed in complex environments such as high altitudes and offshore. The installation, maintenance, and replacement of their power cables require specialized lifting equipment. As a critical carrier for power transmission, the cables are heavy and have complex installation paths, placing extremely high demands on the safety, stability, and adaptability of the lifting equipment. In the operation and maintenance of wind turbine generators, the efficiency of cable lifting directly affects the downtime of the unit, thus impacting power generation efficiency. Furthermore, the working environment often involves risks such as falls from heights and interference from sea winds, imposing stringent requirements on the automation level of the equipment.

[0003] However, existing wind turbine power cable lifting equipment generally adopts a manual coiling and lifting operation mode, which has certain drawbacks in practical applications: On the one hand, manual coiling requires operators to directly contact the cable and apply tension to complete the lifting, which is extremely labor-intensive and has low lifting efficiency, making it difficult to meet the timeliness requirements of operation and maintenance of large-scale wind farms; On the other hand, wind turbines are often deployed in dangerous environments such as high-altitude towers and offshore platforms. When people work at close range, they are easily affected by factors such as wind and equipment swaying, which pose safety hazards such as falling from heights and cable slippage, seriously threatening the personal safety of operators. In addition, uneven control of the lifting force during manual lifting can easily lead to cable imbalance, twisting, and wear, affecting the cable's service life. At the same time, the lack of precision in manual operation makes it difficult to achieve smooth lifting and positioning of the cable, which may cause collision damage to related components of the unit, further increasing operation and maintenance costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wind turbine generator power cable lifting device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A wind turbine generator power cable lifting device includes: a connecting seat, a connecting column on the top of the connecting seat, a support frame plate fixedly installed at the other end of the connecting column, a servo motor fixedly installed on the front side of the support frame plate by bolts, a roller 1 installed on the shaft of the servo motor on the rear side wall of the support frame plate, roller 2 symmetrically installed on the upper and lower sides of the rear side wall of the support frame plate, a circular bent plate 1 and a circular bent plate 2 fixedly installed on the front and rear sides of the support frame plate by bolts respectively, roller 3 symmetrically installed on the rear side of the circular bent plate 1, a synchronous belt installed between roller 1 and roller 3 on the upper and lower sides, the synchronous belt being laid between roller 2 on the upper and lower sides, a gear 1 installed on the shaft of roller 1 on the front side of the circular bent plate 1, a gear 2 fixedly installed on the upper and lower left side of the front side of the circular bent plate 1 by a shaft, a large gear meshing between gear 1 and gear 2, and lifting rollers fixedly installed on the upper and lower sides of the large gear by bolts; The servo motor is used to start the rotation of roller three via a synchronous belt. Roller three drives the large gear to rotate via gear one, and the large gear in turn drives the upper and lower lifting rollers to rotate. The lifting roller is used for cable connection. When the large gear rotates, it rotates and rewinds the cable, thereby lifting it. The connecting seat is used for connection and fixation to the side of the wind turbine.

[0006] Preferably, the surface of the lifting roller is provided with a cable groove; the installation position of the second roller is adjustable, and the second roller is used to tension the synchronous belt.

[0007] Preferably, multiple sets of connectors are provided between the first circular bent plate and the second circular bent plate to enhance structural stability.

[0008] Compared with the prior art, this utility model provides a wind turbine generator power cable lifting device, which has the following beneficial effects: After the servo motor starts, it drives the three rollers to rotate via the synchronous belt, which is efficient in power transmission and has low loss. The coaxial design of the three rollers and the first gear allows the rotational power to be directly transmitted to the first gear. Then, through the meshing transmission between the first gear and the large gear, the large gear is driven to rotate smoothly, which in turn drives the lifting rollers on the upper and lower sides to rotate synchronously, realizing the automated winding and lifting of the cable without direct manual intervention, reducing the labor intensity of operators, and avoiding personal safety risks in dangerous environments. The combination of gear drive and synchronous belt drive ensures the stability and accuracy of power transmission. The meshing of the large gear with gear one and gear two makes the rotation speed of the lifting roller uniform and controllable, and the cable winding process is smooth, effectively avoiding problems such as cable twisting and wear, and ensuring the integrity of the cable.

Detailed Implementation

[0011] 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.

[0012] Reference Figures 1-4 As shown in the figure, a wind turbine power cable lifting device of this embodiment includes a connecting seat 201. The connecting seat 201 serves as a connection carrier between the device and the wind turbine. Its structural design is adapted to the installation interface on the side of the wind turbine. A stable connection is achieved by fixing with bolts to ensure that the device will not be displaced during operation.

[0013] The top of the connecting seat 201 is provided with a connecting column 202. The connecting column 202 and the connecting seat 201 adopt an integrated molding design with high structural strength. The other end of the connecting column 202 is fixedly provided with a support frame plate 203, which provides a solid load-bearing foundation for the assembly of various functional components.

[0014] A servo motor 204 is fixed to the front side of the support frame plate 203 by bolts. The bolt connection method facilitates the disassembly and maintenance of the servo motor 204. The power output end of the servo motor 204 passes through the rear side wall of the support frame plate 203, and a roller 2041 is provided on the rotating shaft to realize the direct transmission of power.

[0015] Rollers 2042 are symmetrically arranged on the upper and lower sides of the rear side wall of the support frame plate 203. The rollers 2042 are connected to the support frame plate 203 through adjustable brackets. Their installation positions can be flexibly adjusted according to the tension of the synchronous belt to tension the synchronous belt and ensure the stability of power transmission.

[0016] The front and rear sides of the support frame plate 203 are respectively fixed with circular curved plate 101 and circular curved plate 202 by bolts. Multiple sets of connectors 206 are also provided between circular curved plate 101 and circular curved plate 202. The connectors 206 are fixed with high-strength bolts, which effectively enhances the structural stability between the two and forms a closed protective frame.

[0017] The circular curved plate 101 is symmetrically equipped with rollers 2043 on the upper and lower sides. A synchronous belt is provided between the rollers 2041 and the rollers 2043 on the upper and lower sides. The synchronous belt is laid between the rollers 2042 on the upper and lower sides, forming a complete synchronous transmission mechanism to ensure the synchronicity of power transmission.

[0018] Gear 2044 is mounted on the shaft of roller 2041 on the front side of the circular curved plate 101. Gear 2044 rotates coaxially with roller 2041. Gear 205 is fixedly mounted on the left side of the front side of the circular curved plate 101 via a shaft. Gear 205 is compatible with gear 2044. A large gear 3 meshes between gear 2044 and gear 205, forming a stable gear transmission system.

[0019] Lifting rollers 301 are fixed to the upper and lower sides of the large gear 3 by bolts. The bolt connection ensures that the lifting rollers 301 rotate synchronously with the large gear 3. The surface of the lifting rollers 301 is provided with cable slots. The size of the cable slots is adapted to the outer diameter of the power cable and is used to limit and fix the cable.

[0020] The servo motor 204 is used to drive the roller 2043 to rotate via the synchronous belt after starting. The roller 2043 drives the large gear 3 to rotate via the gear 2044. The large gear 3 then drives the lifting rollers 301 on the upper and lower sides to rotate. The lifting rollers 301 are used for cable connection. When the large gear 3 rotates, it rotates and winds the cable, thereby realizing cable lifting.

[0021] In some examples, a tension adjustment knob is provided on the side of the support frame plate 203. The tension adjustment knob is connected to the adjustable bracket of the roller 2042, which makes it convenient for the operator to adjust the tension of the synchronous belt in real time during the operation of the equipment, thus improving the ease of operation.

[0022] The working principle of this utility model is as follows: When using the wind turbine power cable lifting equipment, first determine the installation position of the connector 201 based on the installation location of the wind turbine and the cable lifting requirements. Secure the connector 201 to the pre-set installation interface on the side of the wind turbine using bolts, ensuring the connector 201 is firmly installed without any looseness. Then, fix the support frame plate 203 to the connector 201 using the connecting column 202, keeping the support frame plate 203 horizontal and stable, providing a reference for subsequent component assembly.

[0023] The equipment is then assembled and debugged: the servo motor 204 is fixed to the front of the support frame plate 203 with bolts, ensuring that the shaft of the servo motor 204 passes through the rear wall of the support frame plate 203 and is fixedly connected to roller 2041; rollers 2042 are installed at symmetrical positions on the upper and lower sides of the rear wall of the support frame plate 203, and the installation height of rollers 2042 is adjusted so that the synchronous belt can be stably placed between rollers 2041, 2042 and 3043; the circular curved plate 101 and the circular curved plate 202 are fixed to the support frame plate 203 with bolts. Multiple sets of connectors 206 are installed on the front and rear sides of 03 to enhance the connection stability between the two; roller 3 2043 is installed on the rear side of the circular curved plate 101 to correspond with roller 1 2041. After the timing belt is fitted, the position of roller 2 2042 is readjusted to ensure that the timing belt is taut; gear 1 2044, gear 2 205 and large gear 3 are installed on the front side of the circular curved plate 101 to ensure that the gears mesh accurately and without jamming; finally, the lifting roller 301 is fixed to the upper and lower sides of the large gear 3 with bolts, and the cable slot of the lifting roller 301 is checked to see if it is intact.

[0024] After the equipment is assembled, one end of the power cable is inserted into the cable slot of the lifting roller 301, ensuring a tight fit between the cable and the slot to prevent slippage. The servo motor 204 is started, and its shaft drives roller 2041 to rotate. Roller 2041 drives rollers 2043 on both sides to rotate synchronously via a timing belt. The timing belt, tensioned by roller 2042, ensures efficient and slip-free power transmission. The rotation of roller 2041 drives the coaxial gear 2044 to rotate. Gear 2044 meshes with the large gear 3, driving the large gear 3 to rotate smoothly around its axis. Meanwhile, gear 205 provides auxiliary support and guidance to the large gear 3, ensuring uniform force distribution during rotation. The rotation of the large gear 3 directly drives the upper and lower lifting rollers 301 to rotate synchronously. The lifting rollers 301 gradually wind up the cable through the cable slots on their surface, realizing the automated lifting operation of the cable. The operator can remotely control the speed of the servo motor 204 to adjust the cable lifting speed and ensure that the lifting process is stable and controllable.

[0025] If insufficient tension of the synchronous belt is found during operation, the position of roller 2042 can be adjusted by the tension adjustment knob on the side of the support frame 203 to maintain appropriate tension of the synchronous belt.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
