Problems solved by technology
[0002] The role of the hub bracket is to connect the hub shell with the metal parts of the hub to ensure the smooth operation of the hub shell according to the design angle; if damage, cracking, etc. occur, it will cause serious accidents such as fan shutdown
Since the hub bracket is installed in the hub casing, when the hub bracket is damaged after the fan assembly is completed, it is extremely difficult to replace and repair it, and because the fan is full of oil stains, electric welding and other operations are not allowed
Before this design, if the hub bracket needs to be replaced or repaired, the whole machine needs to be hoisted from a high altitude, and the disassembly and replacement can only be carried out on the ground, which is expensive

The invention creatively provides a repairing method for a fan hub support. The method comprises the following steps that 1, a repairing jacket needing to be used is determined according to the damaged position of the hub support, and the jacket mounting position is determined; 2, the damaged position of a hub is adjusted; 3, the jacket is assembled on the fractured hub support, and the drilling position is determined; 4, a through hole is drilled in the hub support according to the drilling position; and 5, the jacket is installed and fixed to the hub support through a fastener. The hub support is repaired under the state of not dismounting the fan hub, the high hoisting and replacing expenses are avoided; and when the hub support is damaged, the damaged position is repaired only throughthe jacket with the high matching degree according to the damaged portion, and after the jacket is installed on the support, the good supporting and fixing functions are achieved, and the efficiency for solving problems is greatly improved.
Description
technical field [0001] The invention belongs to the field of wind turbine repair equipment, and in particular relates to a repair method for a wind turbine hub bracket. Background technique [0002] The role of the hub bracket is to connect the hub shell with the metal parts of the hub to ensure the smooth operation of the hub shell according to the design angle; if damage, cracking, etc. occur, it will cause serious accidents such as fan shutdown. Since the hub bracket is installed in the hub casing, when the hub bracket is damaged after the fan assembly is completed, it is extremely difficult to replace and repair it, and because the fan is covered with oil stains, electric welding and other operations are not allowed. Before this design, if the wheel hub bracket needs to be replaced or repaired, the whole machine needs to be hoisted from a high altitude, and the disassembly and replacement can only be carried out on the ground, which is expensive. Therefore, a fan wheel ...
