Description

Technical Field

[0001] The utility model relates to the technical field of brakes, in particular to a wind power mechanical brake which is convenient for replacing brake pads. Background Art

[0002] Wind turbine mechanical brake is a key safety device for wind turbines. When the wind turbine needs to shut down or encounters an emergency, the mechanical brake can quickly lock the wind rotor to prevent it from continuing to rotate, thereby ensuring the safety of the unit. Wind turbine mechanical brakes are usually composed of brake discs, brake calipers, brake pads and springs. Under normal working conditions, the brake is in a released state and the wind rotor can rotate freely. When it is necessary to shut down or encounter an emergency, the control system will issue a command to make the brake caliper clamp the brake disc and prevent the wind rotor from rotating through the friction between the brake pads and the brake disc. Wind turbine mechanical brakes have the advantages of simple structure, high reliability and large braking torque. However, it also has some disadvantages, such as the heat generated during braking may cause the brake pads to wear faster and need to be replaced regularly. In addition, mechanical brakes may generate large noise and vibration during braking.

[0003] When using a wind turbine mechanical brake, since it is necessary to ensure the efficiency of the subsequent maintenance of the wind turbine mechanical brake, it is necessary to ensure that the brake pads in the wind turbine mechanical brake are easy to disassemble. However, we consider that the brake pads in the prior art are all installed in an integral fixed manner, which will make the subsequent disassembly and maintenance extremely time-consuming and labor-intensive, and will also affect the installation speed, which is extremely inconvenient. Therefore, a wind turbine mechanical brake that is easy to replace the brake pads is urgently needed to solve the above problems. Utility Model Content

[0013] The utility model discloses a wind turbine mechanical brake which is convenient for replacing brake pads. When the brake pads need to be replaced, the two cylinders are first started to drive the brake pads downward through the side plates so that the brake pads are separated from the brakes. At this time, the side plates and other components at the bottom of the side plates can be disassembled. Finally, the brake pads can be disassembled by utilizing the notches in the brake pads. Compared with the brakes in the prior art, the brake pads are all installed in an integral fixed manner, which makes the subsequent disassembly and maintenance extremely time-consuming and labor-intensive, and also affects the installation speed.
