[0033] Working principle: A convenient yaw brake replacement device solves the problem of long-term lifting by personnel when disassembling and installing the brake. When disassembling the brake, the remaining bolts must be removed, so the tray must be placed at the center of the bottom of the yaw brake. The movable bracket only moves vertically, and the contact area of the tray base 302 is larger than that of the brake, so no deflection will occur. In actual operation, when rising or falling, the operator usually holds it steady to prevent it from slipping. When the brake needs to be moved to the platform, the movable bracket is lowered to the bottom of the stroke, and the height is more suitable for personnel to carry. It is directly removed from the bracket and placed on the fan platform. When installing the brake, the bolts must be installed in line with the bolt holes. Displacement adjustment may occur. To avoid displacement and tilt of the bracket, pay attention to the method of use, that is, before installing the brake, place the bracket support position basically below the center position, and then lift it to the installation position together with the brake, and leave a gap of 1~2cm. The space between the installation position of the brake and the fan platform is basically filled with the brake and the bracket to avoid tilting. When installing the bolts, you only need to move the brake on the bracket for fine-tuning. First align a bolt hole and fix the bolt, then adjust the position of the bracket or brake as a whole, and install the remaining bolts. This can avoid displacement and deflection of the bracket, thus completing a convenient yaw brake replacement device.
