Abstract
The invention discloses a device for cleaning a threaded rod locked in an embedded bolt sleeve at the root of a blade. The device comprises a positioning tool and cleaning equipment, wherein the positioning tool comprises a positioning steel plate, positioning round pins, fixing bolts and a guide sleeve; positioning holes, fixing holes and a cleaning positioning hole are formed in the positioning steel plate; the positioning round pins penetrate through the positioning holes to position the positioning steel plate on the end part of the root of the blade; the fixing bolts penetrate through the fixing holes to fix the positioning steel plate on the end face of the root of the blade; the guide sleeve is inserted into the cleaning positioning hole to determine the position to be cleaned of the threaded rod; the internal diameter of the guide sleeve is slightly smaller than the minor diameter of a thread of a bolt hole of the embedded bolt sleeve; the cleaning equipment comprises a drilling tool and tapping equipment for carrying the threaded rod out of the bolt hole of the embedded bolt sleeve; a drill bit of the drilling tool penetrates through the guide sleeve, and extends into the threaded rod. The device is easy to operate, low in energy consumption, high in cleaning efficiency and short in cleaning time; the locked threaded rod can be cleaned under the condition of not damaging the internal thread of the embedded bolt sleeve. The invention further provides a method for cleaning the threaded rod locked in the embedded bolt sleeve at the root of the blade.
Description
technical field [0001] The invention belongs to the technical field of wind power blade installation, and mainly relates to a device and a method for cleaning screw rods fixed in pre-embedded bolt sleeves at blade roots. Background technique [0002] The main component of epoxy series wind power blades is epoxy glass fiber reinforced plastic, which is formed by mixing glass fiber cloth and epoxy resin. Bolt holes are set at the root of the blades to fix the blades on the wind power host. Some methods of forming bolt holes at the root of the blade adopt the bolt sleeve pre-embedded molding process, that is, when the blade is formed, the bolt sleeve is pre-embedded at the root of the blade, and after molding and solidification, the bolt can be directly connected to fix the blade on the wind power host. In the pre-embedded forming process of bolt sleeves, in order to ensure that the bolt sleeves are evenly distributed on the blade root according to the size of the drawing, a se...
