Description

Technical Field

[0001] This utility model relates to the field of belt pulley support frame technology, and in particular to a support frame for a wind turbine belt pulley. Background Technology

[0002] A windmill is a type of powered machine that does not require fuel and uses wind as its energy source. In real life, the operation of a windmill by an electric motor consumes a lot of energy, and a relatively high-power electric motor is required in conjunction with a transmission mechanism to drive the windmill. The pulley and transmission belt transmission mechanism has a simple structure, low cost, is easy to manufacture and maintain, runs smoothly, has low noise, and can provide a quiet working environment. It is a commonly used transmission mechanism. However, after the pulley is processed, it needs to be installed on a support frame to test its rotational stability.

[0003] The existing support frame is U-shaped. Workers install a shaft at the center of the pulley, then place the shaft on the support frame. The pulley is manually rotated, and its balance is judged based on the rotation path. Before testing, workers need to lift the pulley and shaft and place the shaft on the support frame. However, the pulley and shaft are heavy, requiring a lot of physical effort to lift and easily causing back and arm injuries. If the pulley and shaft fall during handling, it will not only damage the equipment but also injure nearby workers, causing a safety accident. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a support frame for a wind turbine pulley, aiming to improve the existing technology where the pulley and shaft are too heavy, requiring a lot of physical strength to lift and easily causing waist and arm injuries. In addition, if the pulley and shaft fall during transportation, it will not only damage the equipment but also injure nearby workers, causing safety accidents.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a support frame for a wind turbine pulley, comprising a horizontal bar, with square tubes fixedly connected to both ends of the horizontal bar, and vertical bars fixedly connected to the top of both ends of the square tubes. A bearing rod is fixedly connected to the upper end of two adjacent vertical bars, and an installation rod is fixedly connected to the middle of two adjacent vertical bars. A lifting frame is rotatably connected to the outer wall of the installation rod via a connecting shaft. A positioning groove is provided at the upper end of the outer wall of the lifting frame, and a rotating shaft is provided on the outer wall of the positioning groove. A pulley is fixedly connected to the outer wall of the rotating shaft. A traction rope mechanism is provided on the outer wall of the lifting frame, and the traction rope mechanism is used to limit the rotating shaft.

[0006] Through the above technical solution: the crossbar can support two square tubes fixedly connected at both ends, forming a stable overall frame foundation between the crossbar and the square tubes. Vertical bars are fixedly connected to the top of both ends of the square tubes. These two vertical bars provide vertical support for the entire support frame, ensuring the vertical stability of the structure. A load-bearing rod is fixedly connected to the upper end between the two adjacent vertical bars. The load-bearing rod supports the pulley, ensuring that the pulley is always in a stable state. An installation rod is fixedly connected to the middle between the two adjacent vertical bars. The outer wall of the installation rod is rotatably connected to the lifting frame through a connecting shaft. The connecting shaft allows the lifting frame to rotate around the connecting shaft. A positioning groove is opened at the upper end of the outer wall of the lifting frame. The positioning groove can accurately fix the rotating shaft, provide stable lateral positioning, and prevent the rotating shaft from shifting left or right.

[0007] As a further description of the above technical solution:

[0008] The traction rope mechanism includes a first fixing pin, one end of which is fixedly connected to the outer wall of the lifting frame. A fixing block is fixedly connected to the bottom of the lifting frame. A second fixing pin is fixedly connected to the outer wall of the fixing block. A winch is rotatably connected to the outer wall of the lifting frame. A rope is fixedly connected to the outer wall of the first fixing pin, and the other end of the rope is wound around the outer wall of the winch.

[0009] Through the above technical solution: one end of the fixing pin is fixedly connected to the outer wall of the lifting frame, ensuring that the two form a stable whole, providing a solid foundation for subsequent traction operations. The bottom of the lifting frame is fixedly connected to a fixing block, and the outer wall of the fixing block is fixedly connected to the fixing pin. The outer wall of the lifting frame is connected to the rotation of the winch, allowing the winch to rotate flexibly around the connection point, providing a basis for the rope winding and unwinding operations. The outer wall of the fixing pin is fixedly connected to one end of the rope, and the other end of the rope is wound around the outer wall of the winch. When the winch is driven by external power to rotate forward and backward, the rope winding and unwinding operations can be realized in an orderly manner.

[0010] As a further description of the above technical solution:

[0011] Each of the two lifting frames is fixedly connected to a fixed pile on one of its adjacent sides, and the outer wall of the fixed pile is rotatably connected to a collar.

[0012] The above technical solution involves two lifting frames being securely connected to fixed piles on adjacent sides. The outer wall of the fixed pile is rotatably connected to a collar, which fits tightly against the outer wall of the fixed pile and can rotate flexibly around the axis of the pile.

[0013] As a further description of the above technical solution:

[0014] A connecting rope is fixedly connected to the outer wall of the collar, and a pedal is fixedly connected to the other end of the connecting rope.

[0015] The above technical solution involves fixing a connecting rope to the outer wall of the collar, with a pedal fixedly connected to the other end of the rope to apply downward pressure.

[0016] As a further description of the above technical solution:

[0017] One end of the fixing pin two is fixedly connected to the limiting block two, and multiple limiting rings are fixedly connected to the outer wall of the fixing pin two.

[0018] Through the above technical solution: one end of the fixed pin two is fixedly connected to the limiting block two, the limiting block two performs precise limiting to prevent excessive displacement, and the outer wall of the fixed pin two is fixedly connected to the limiting ring, which enhances the stability and reliability of the fixed pin two during the working process.

[0019] As a further description of the above technical solution:

[0020] A rocker arm is rotatably connected to the outer wall of the winch, and the rocker arm is eccentrically positioned.

[0021] Through the above technical solution: the outer wall of the winch is rotatably connected to the rocker arm, ensuring efficient and stable power transmission. The rocker arm adopts an eccentric setting, which allows a larger winch rotation effect to be obtained with a smaller force, greatly optimizing the convenience and labor-saving of operation.

[0022] As a further description of the above technical solution:

[0023] The top surface of the pedal is provided with anti-slip texture, and one end of the fixing post is fixedly connected to a limit block.

[0024] Through the above technical solution: the top surface of the pedal is provided with anti-slip texture, which effectively increases the friction between the sole of the shoe and the surface of the pedal and prevents operational errors. One end of the fixed post is firmly fixed to the limit block, which effectively avoids equipment damage caused by excessive displacement.

[0025] As a further description of the above technical solution:

[0026] The lifting frames are symmetrically arranged and are force-saving levers.

[0027] The above technical solution involves symmetrically distributing the lifting frames on both sides of the device, resulting in a more even distribution of force. This ensures balance and stability when lifting heavy objects, preventing tilting or tipping. The lifting frames act as force-saving levers, requiring only a relatively small force to easily lift heavier objects through the lever's amplification effect, significantly improving work efficiency and reducing labor intensity.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the rotating shaft is installed in the middle of the pulley and rolls to the end of the lifting frame near the positioning groove. The lifting frame is rotated to lower the end near the positioning groove, and the outer wall of the rotating shaft is engaged in the positioning groove. Then, the pedal is pressed down to raise the end of the lifting frame near the positioning groove. The rotating shaft slides down the outer wall of the lifting frame to the top surface of the bearing rod for testing. This makes it easy to move the pulley to the testing position, greatly reducing manual labor and avoiding safety accidents.

[0030] 2. In this utility model, one end of the rope is fixed to the outer wall of the fixing pin, and the other end passes through a limiting ring, wraps around the rotating shaft once, and then passes back through the middle of another limiting ring, and finally winds around the winch. When the winch is fixed, the rotating shaft is fixed. When the winch is loosened, the rotating shaft is slowly lowered, making the movement smoother. Attached Figure Description

[0042] Specifically, one end of the fixing pin 201 is fixedly connected to the outer wall of the lifting frame 7, ensuring that the two form a stable whole and providing a solid foundation for subsequent traction operations. The bottom of the lifting frame 7 is fixedly connected to the fixing block 205, and the fixing pin 202 is fixedly connected to the outside of the fixing block 205. The outer wall of the lifting frame 7 is rotatably connected to the winch 204, allowing the winch 204 to rotate flexibly around the connection point, providing a basis for the winding and unwinding of the rope 203. The outer wall of the fixing pin 201 is fixedly connected to one end of the rope 203, and the other end of the rope 203 is wrapped around the outer wall of the winch 204. When the winch 204 is driven by external power to rotate forward and backward, the winding and unwinding of the rope 203 can be realized in an orderly manner.

[0043] Please see the appendix Figure 1 - Appendix Figure 3 Two lifting frames 7 are fixedly connected to adjacent sides of fixed piles 12. The outer wall of the fixed pile 12 is rotatably connected to a collar 13. The outer wall of the collar 13 is fixedly connected to a connecting rope 14.

The outer wall of the fixed pin 202 is fixedly connected to multiple limit rings 19.

[0044] Specifically, each of the two lifting frames 7 is firmly connected to a fixed pile 12 on one side. A collar 13 is rotatably connected to the outer wall of the fixed pile 12. The collar 13 fits tightly against the outer wall of the fixed pile 12 and can rotate flexibly around the axis of the pile. A connecting rope 14 is fixedly connected to the outer wall of the collar 13. A footboard 15 is fixedly connected to the other end of the connecting rope 14.

A limiting ring 19 is fixedly connected to the outer wall of the second fixed pin 202 to enhance the stability and reliability of the second fixed pin 202 during operation.

[0045] Please see the appendix Figure 3 - Appendix Figure 5 The outer wall of the winch 204 is rotatably connected to a rocker arm 18, which is eccentrically positioned. The top surface of the pedal 15 is provided with anti-slip texture 20. One end of the fixed pile 12 is fixedly connected to a limit block 16. The lifting frame 7 is symmetrically arranged and is a force-saving lever.

[0046] Specifically, the outer wall of the winch 204 is rotatably connected to the rocker arm 18 to ensure efficient and stable power transmission. The rocker arm 18 adopts an eccentric setting, which allows for a larger rotation effect of the winch 204 with a smaller force, greatly optimizing the convenience and labor-saving of operation. The top surface of the pedal 15 is provided with anti-slip texture 20, which effectively increases the friction between the sole of the shoe and the surface of the pedal 15 and prevents operational errors. One end of the fixed stake 12 is firmly fixed to the limit block 16, which effectively avoids equipment damage caused by excessive displacement. The lifting frame 7 is symmetrically distributed on both sides of the device, which makes the force distribution more even. When undertaking the task of lifting heavy objects, it can maintain balance and stability and avoid tilting or tipping. The lifting frame 7 is a labor-saving lever. Only a relatively small force needs to be applied to easily lift heavy objects by means of the lever amplification effect, which greatly improves work efficiency and reduces labor intensity.

[0047] Working principle: The rotating shaft 11 is installed in the middle of the pulley 10 and rolls to the end of the lifting frame 7 near the positioning groove 8. The lifting frame 7 is rotated to lower the end near the positioning groove 8, and the outer wall of the rotating shaft 11 is engaged in the positioning groove 8. Then, the pedal 15 is pressed down to raise the end of the lifting frame 7 near the positioning groove 8. The rotating shaft 11 slides down the outer wall of the lifting frame 7 to the top surface of the bearing rod 5 for inspection. This makes it easy to move the pulley 10 to the inspection position, greatly reducing manual labor and avoiding safety accidents.

[0048] One end of the rope 203 is fixed to the outer wall of the fixing pin 201, and the other end passes through a limiting ring 19, wraps around the rotating shaft 11 once, and then passes back through the middle of another limiting ring 19, and finally winds around the winch 204. When the winch 204 is fixed, the rotating shaft 11 is fixed. When the winch 204 is loosened, the rotating shaft 11 is slowly lowered, making the movement smoother.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
