Assembly-type blade tip clamping overhauling device

Abstract

The invention provides an assembly-type blade tip clamping overhauling device mainly applied to repairing work of the front end of a rotator blade of a wind turbine. The assembly-type blade tip clamping overhauling device comprises a base platform, a fixed framework erected on the base platform and a worktable installed on the fixed framework for clamping a blade tip. The base platform is formed by connecting of cross beams, longitudinal beams and guide wheels. The fixed framework is composed of guiding rods, a framework body and guiding wheels. The worktable is composed of a square framework, hooks and a manual winch. The main parts of the blade tip clamping overhauling device are all installed on a blade tip overhauling hanging basket platform; the workload of blade tip repairing is reduced greatly; maintenance difficulty is effectively reduced through the technical scheme; and the assembly-type blade tip clamping overhauling device is suitable for overhauling light and thin flake objects and complex application environments and has the characteristics of being easy to disassemble and assemble, easy to transport, simple in structure, convenient to operate, high in safety and other characteristics.

[0002] Troubleshooting and maintenance of rotor blades on wind turbines is currently a time consuming, relatively dangerous and also expensive task

Prior art clamping devices often consist of a frame (also known as a yoke) and multiple straps that are wrapped around at least a portion of the rotor blade to clamp the rotor blade in place, which involves many Manual assistance, especially when it comes to small-scale maintenance and modification of the tip of the blade, the overall disassembly and assembly of the appeal will be more time-consuming and labor-intensive. At this stage, lightning damage to the tip of the blade and technical replacement of the tip of the blade are very frequent. Due to the irregular shape of the blade tip that needs to be replaced Moreover, the weight is heavy, and it will be very difficult for maintenance personnel to stand on a typical hanging basket to overhaul at a specified height, so there is an urgent need for a blade tip clamping and repairing device that is used in conjunction with the hanging basket, and the blade tip clamping and repairing device must be very Precisely oriented towards the rotor blade so that the blade tip that needs to be replaced fits into the rotor blade. Furthermore, the blade tip clamping overhaul device must be manually operated at high altitude, which involves work at considerable heights, technical Personnel operate from said bucket during assembly or disassembly of the blade tip

[0003] In general, connecting the tip to the rotor blade is a major problem due to the fact that when the tip holder is placed on the basket and the tip is in the correct position relative to the rotor blade, during this adjustment , necessitating extensive manual adjustment
