Description

Technical Field

[0001] The utility model relates to the technical field of fan maintenance, in particular to an adjustable bracket for a fan bolt broken wire removal device. Background Art

[0002] At present, a large number of high-strength bolts are used in various connection parts of wind turbines. During the operation of the wind turbine, due to the unstable wind conditions, the wind turbine is often subjected to unstable loads, especially the connection bolts at the wind turbine bearings, which are subjected to unstable loads all year round, often causing bolt breakage, and it is relatively difficult to remove the bolts broken in the hole. The traditional method of removing the bolts is: first, determine the broken wire position, select a suitable drill bit, fix the drill bit on the extension rod, and connect it to the pistol drill, then install the locator, and after assembly, the construction personnel hold the device to perform drilling work. After the drilling is completed, use a hammer to hit one side of the homemade broken wire extractor into the drilled hole, and then use a wrench to rotate the other side to remove the broken wire.

[0003] Since the heights of high-strength bolts at the connection parts of various types of fans are different, when construction workers hold the broken wire removal device to work, if the bolt height is high, the construction workers need to tiptoe or use tools such as ladders to carry out construction; if the bolt height is low, the construction workers need to bend over or squat to carry out construction, which is difficult and has certain safety hazards; in addition, due to holding the tools for a long time in an uncomfortable posture, the construction workers may hold the tools unsteadily and shake, which may cause the drilling position to shift and reduce work efficiency.
