Description

Technical Field

[0001] The present application relates to the technical field of wind turbines, and in particular to a brake pad replacement device. Background Art

[0002] The wind turbine yaw brake is one of the important components used to adjust the direction of the wind turbine in a wind turbine. It is usually a disc-shaped or fan-shaped structure located on the top of the wind turbine, which can change the wind direction and angle of the wind turbine by twisting or moving when necessary, so as to maximize the capture of wind energy or avoid mechanical damage caused by excessive wind force.

[0003] At present, the process of replacing brake pads is basically carried out by manual disassembly and assembly. After taking out the retaining spring, fan, yaw brake and other components, the workers use tools such as screwdrivers to support them on the fan body to lift the brake pads and remove them. In the process of lifting the brake pads, if you are not careful, you may be scratched by their sharp edges, which poses certain safety hazards. Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the shortcomings existing in the background technology and to propose a brake pad replacement device to solve the problems existing in the prior art.

[0006] Preferably, the driving mechanism includes a tripod arranged inside the fixed frame, and the inner side of the tripod is slidably connected with a push-pull plate. The position of the adjusting jaws can be adjusted by the driving mechanism, so that three groups of symmetrically distributed adjusting jaws cooperate with the inner arc concave plate at the bottom to stably clamp the brake pad.

[0007] Preferably, a motor is fixedly mounted on the top of the fixing frame, and a driving shaft is fixedly connected to the output end of the motor.

[0008] Preferably, a disc is fixedly sleeved on the outer surface of the driving shaft, and guide arc holes are opened on the outer surface of the disc. There are three groups of guide arc holes designed and symmetrically distributed on the surface of the disc. There are three groups of guide shafts and other components related thereto, which correspond to the corresponding push-pull plates and positioning clamps.

[0009] Preferably, a guide shaft is fixedly connected to the outer surface of the push-pull plate, and the outer surface of the guide shaft is slidably connected to the inner side of the guide arc hole.

[0010] Preferably, a push shaft is fixedly provided on one end of the push-pull plate away from the tripod, and the outer surface of the push shaft is rotatably connected to the top end of the position adjusting clamping claw.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The brake pad replacement device can stably clamp the brake pad and automatically control its movement and rotation process through the driving mechanism and linkage components. Compared with the manual replacement method of using a screwdriver or other tools to lift the brake pad, this relatively automated operation can reduce the impact of human factors and improve the stability and safety of the operation.

[0013] 2. The brake pad replacement device, through the driving mechanism and linkage components, can quickly and accurately stably clamp the brake pad and adjust the angle, making the replacement process smoother and more efficient. Workers only need to operate the handle part of the device, without the need to use additional tools such as screwdrivers to lift the brake pad, which saves operation time and keeps away from the brake pad.

[0019] See also Figure 1-3A brake pad replacement device comprises a fixing frame 1, a handle 2 is fixedly connected to the top of the fixing frame 1, a fixing block 3 is fixedly connected to the outer surface of the fixing frame 1, a first shaft 4 is fixedly penetrated through the inner side of the fixing block 3, a Y-shaped frame 5 is rotatably connected to the outer surface of the first shaft 4, a second shaft 6 is fixedly penetrated through the end of the Y-shaped frame 5 away from the first shaft 4, and a positioning clamp 7 is rotatably connected to the outer surface, an inner arc concave plate 8 is fixedly connected to the bottom of the positioning clamp 7, and a driving mechanism for adjusting the position of the inner arc concave plate 8 is arranged inside the fixing frame 1.

[0020] Through the above technical solution, during the process of replacing the brake pad, the device can adjust the positions of the three groups of adjusting jaws 7 through the driving mechanism, so that the three groups of evenly distributed inner arc concave plates 8 are stably stuck at the edge of the brake pad, and the brake pad can be removed stably and safely in conjunction with the handle 2.

[0021] Specifically, the driving mechanism includes a tripod 9 arranged inside the fixing frame 1 , and a push-pull plate 10 is slidably connected to the inner side of the tripod 9 .

[0022] Through the above technical solution, the push-pull plates 10 sliding inside the tripod 9 are substantially at the same vertical angle with the corresponding positioning jaws 7, so as to stably drive the positioning jaws 7.

[0023] Specifically, a motor 11 is fixedly mounted on the top of the fixing frame 1 , and a driving shaft 12 is fixedly connected to an output end of the motor 11 .

[0024] Through the above technical solution, the driving shaft 12 will be linked to the disc 13 to rotate during the rotation process, and the guide arc hole 14 will make a circular motion during this process.

[0025] Specifically, a disc 13 is fixedly sleeved on the outer surface of the driving shaft 12 , and a guide arc hole 14 is opened on the outer surface of the disc 13 .

[0026] Through the above technical solution, the guide arc holes 14 will respectively drive the corresponding guide shafts 15 to deviate during the rotation process, thereby linking the push-pull plate 10 to slide along the inner side of the tripod 9.

[0027] Specifically, the outer surface of the push-pull plate 10 is fixedly connected with the guide shaft 15 , and the outer surface of the guide shaft 15 is slidably connected with the inner side of the guide arc hole 14 .

[0028] Through the above technical solution, the guide shaft 15 cooperates with the guide arc hole 14 to guide and transmit movement, and can convert the rotation of the disk 13 into the displacement of the three push-pull plates 10.

[0029] Specifically, a push shaft 16 is fixedly penetrated through one end of the push-pull plate 10 away from the tripod 9 , and an outer surface of the push shaft 16 is rotatably connected to the top end of the position adjustment clamping claw 7 .

[0030] Through the above technical solution, the push-pull plate 10 can drive the position-adjusting jaw 7 through the push shaft 16 during the pushing process, and the position-adjusting jaw 7 will rotate along the push shaft 16 during this process.

[0031] Working principle: During the process of replacing the brake pads in the wind turbine, the device can first stably clamp the brake pads through the driving mechanism after unlocking other components, that is, turn on the motor 11 to drive the driving shaft 12 to rotate, thereby linking the disc 13 to rotate synchronously. During the rotation of the disc 13, the three groups of guide arc holes 14 will make circular motions at the same time, and the rotation of the guide arc holes 14 will drive the corresponding guide shafts 15 to deviate. During this period, the guide shafts 15 will link the push-pull plate 10 to make it slide outward synchronously along the inner side of the tripod 9, and the outward movement of the push-pull plate 10 will drive the top of the adjustment jaw 7 through the push shaft 16, so that the adjustment jaw 7 moves along the first As the two shafts 6 rotate, the Y-shaped frame 5 will rotate along the fixed block 3 to cooperate with the positioning jaws 7 to deflect the angle until the bottom ends of the three groups of positioning jaws 7 are close to each other, and the three groups of evenly distributed inner arc concave plates 8 are stably and firmly clamped on the edge of the brake pad at the same time. Finally, hold the two groups of handles 2 and pull upward with force to remove the brake pad smoothly. Compared with the traditional replacement method of lifting the brake pad with the help of a screwdriver, the brake pad or surrounding components may be damaged if the operation is not careful or the force control is not accurate. The stable clamping of the brake pad in the present application can effectively reduce this risk and protect the key components of the wind turbine from damage.

[0032] In summary, the brake pad replacement device of the present application not only improves the safety and efficiency of operation, but also improves the accuracy and stability of operation, reduces the risk of human errors and accidents in work, and is an important technological advancement in modern wind turbine maintenance work.
