Abstract
The utility model provide a kind of for by fan blade bolt take out equipment, comprise magnetic drill press, with the drilling rod be arranged on its power transmission shaft and the drill bit be connected with drilling rod, magnetic drill press is arranged on absorption platform.The utility model is simple and reasonable for structure, the bolt of fracture in blade deep hole just can be removed when carrying out high-temperature heating, make to have broken the blade of bolt without depot repair, for user saves high blade maintenance cost, improve the availability of blower fan, economic benefits, solves the break bolt shortcoming that cannot be removed being coated with locking glue.
Description
Technical field
The utility model relates to a kind of bolt extraction device, especially a kind of equipment for being taken out by bolt in fan blade.
Background technology
After wind power generating set long-play, just easily there is fracture damage in blade set bolt.Bolt fracture situation is generally divided into following two kinds of situations, and the first plane of disruption is concordant with pitch variable bearings flange face, and the second plane of disruption is in pitch variable bearings flange deep hole.
Wherein, the relatively good process of the first situation, and the second plane of disruption is owing to being in pitch variable bearings flange deep hole, and there is no specific purpose tool at present, be therefore difficult to take out; In addition, in order to avoid bolt looseness, because of upper warp, all smear locking glue on bolt surface when mounted, made bolt more be difficult to take out.Because blade bolt locking glue is that high strength is exempted to tear type open, normally tears this bolt open and must carry out high-temperature heating to destroy the character of glue, but blade takes out by the heating way that can not adopt that glass-reinforced plastic material makes.
Because existing bolt extractor is reverse screw thread pyramidal structure, and the above-mentioned locking torque value of bolt having smeared high strength locking glue is much larger than a torque value of getting for reverse silk fetching equipment, and therefore bolt also cannot take out by existing bolt extractor.
Summary of the invention
For the weak point existed in the problems referred to above, the utility model provides a kind of equipment being used for being taken out by bolt in fan blade that the bolt ruptured in blade deep hole can be taken out.
For achieving the above object, the utility model provides a kind of equipment for being taken out by bolt in fan blade, comprise magnetic drill press (1), with the drilling rod be arranged on its power transmission shaft (3) and the drill bit (4) that is connected with described drilling rod (3), described magnetic drill press (1) is arranged on absorption platform (2).
The above-mentioned equipment for being taken out by bolt in fan blade, wherein, described absorption platform (2) is fixed on the blade that closes on, is provided with the bolt fixing hole (21) for being connected with blade on its surface.
The above-mentioned equipment for bolt in fan blade is taken out, wherein, described drilling rod (3) is made up of drill pipe body (31) and the drilling rod link (32) be arranged on its top end face, the inside of described drill pipe body (31) is hollow form structure, its bottom end face is the port (33) of unenclosed construction, and the top of described drill bit (4) is arranged on the inside of described drill pipe body (31) through described port (33).
The above-mentioned equipment for bolt in fan blade is taken out, wherein, the lateral cross section of described drill pipe body (31) is cylindrical structural, and described drilling rod link (32) is arranged on the home position of described drill pipe body (31).
The above-mentioned equipment for bolt in fan blade is taken out, wherein, described drill bit (4) for diameter be the high drill bit of 23mm.
Compared with prior art, the utility model has the following advantages:
The utility model is simple and reasonable for structure, the bolt of fracture in blade deep hole just can be removed when carrying out high-temperature heating, make to have broken the blade of bolt without depot repair, for user saves high blade maintenance cost, improve the availability of blower fan, economic benefits, solves the break bolt shortcoming that cannot be removed being coated with locking glue.
