Abstract
The invention particularly discloses a disassembly and assembly tool for a cooling fan of a wind driven generator. The disassembly and assembly tool for the cooling fan of the wind driven generator solves the problems that an existing cooling fan of the wind driven generator is prone to damage in the disassembly and assembly process, efficiency is low, and potential safety hazards exist. The disassembly and assembly tool for the cooling fan of the wind driven generator comprises a pressing disk and a pressing pipe. A protruding disk integrated with the pressing disk is arranged at the center of the left end face of the pressing disk. The outer diameter of the protruding disk is equal to the inner diameter of the pressing pipe. Seven threaded holes, four pulling rods and three bolts are arranged on the pressing disk. The four pulling rods and the three bolts are matched with the seven threaded holes. The two ends of each pulling rod are provided with threads. Nuts are arranged at the right ends of the pulling rods. Four of the threaded holes are evenly distributed on the portion, on the outer side of the protruding disk, of the pressing disk. The other three threaded holes are evenly distributed on the portion, on the inner side of the protruding disk, of the pressing disk. The disassembly and assembly tool thoroughly solves the potential failure problem of the generator and thoroughly eliminates potential safety hazards caused when the cooling fan of the generator is disassembled and assembled through flames or in an electric furnace heating manner, and meanwhile, the running efficiency of a wind turbine generator is improved.
Description
Technical field
The present invention relates to the dismantling device in wind-powered electricity generation field, be specially the dismounting of a kind of wind-driven generator cooling fan, erecting tools.
Background technology
Along with the fast development of wind-powered electricity generation industry, and the rapid expansion of Wind turbines installed capacity, regular maintenance and the maintenance capacity of the Wind turbines run in wind power plant also roll up thereupon.Cooling fan, as the important spare part of cage modle wind-driven generator, when processing wind-driven generator fault and regular maintenance, is one of parts often needing to remove and install.
The engine room structure feature of the Wind turbines of assembling cage modle wind-driven generator: 1, the tower top cabin distance ground level 50 meters of Wind turbines, and engine room inside compact conformation, narrow space; 2, the generator driven water flat dip in cabin 5 ° installation, and the cooling fan of generator to be in plane be the cabin afterbody of 10 ° of angles; 3, personnel are comparatively difficult in the various operations of cabin afterbody.Therefore, when removing and installing cooling fan in the tower top cabin of generating set, result is often undesirable, even can leave over the hidden danger of lower fire or dynamo bearing fault.
The way that when removing and installing cooling fan in current Wind turbines tower top cabin, many employings are knocked or use flame heating or the equipment such as induction heater, Electric stove to remove and install the mode that cooling fan fan heats; There is following weak point in this dismounting mode: 1, easily makes cooling fan be out of shape, ruptures, destroy dynamic balancing during generator operation, Generator Vibration value is strengthened, and then can cause bearing fault or other faults of generator; In the process of 2, knocking, the damage of generator drive gear end and non-transmision end bearing can be caused, leave the potential faults of bearing; 3, operation is by the restriction of cabin space, inefficiency; 4, because cooling fan volume is comparatively large, engine room inside narrow space, the limited location of heating placed by induction heater and cooling fan, and the effect of heating is undesirable; 5, there is many potential safety hazards with the mode of heating of flame or Electric stove, easily lead to the danger of fire.
Summary of the invention
There is easy damaged fan, inefficiency and the serious problem of potential safety hazard to solve the dismounting of existing wind-driven generator cooling fan in the present invention, provides the dismounting of a kind of wind-driven generator cooling fan, erecting tools.
The present invention adopts following technical scheme to realize: the dismounting of wind-driven generator cooling fan, erecting tools, comprise platen, pressure pipe, the center, left side of platen is provided with the protruding disk with its one, the external diameter of protruding disk is identical with the internal diameter of pressure pipe, platen is provided with pull bar and three bolts of seven screws and the four piece TBE (threaded both ends)s supporting with its seven screws, the right-hand member of pull bar is provided with nut, wherein on four uniform platens be distributed in outside protruding disk of screw, on the uniform platen be distributed in inside protruding disk of other three screws.
When carrying out cooling fan dismounting, first the left end of four pull bars is screwed on the holder of cooling fan, subsequently pressure pipe is enclosed within protruding disk, four screw correspondences of platen outside are through on four pull bars, and be tightened in the rotating shaft of generator by bolt through the screw of platen inside, now, the nut of four pull bar right-hand members is tightened by symmetry, pulling force is passed to cooling fan by pull bar by pressing plate, on the alternator shaft making strength be delivered to horizontal tilt 5 ° evenly, evenly and cooling fan, realize the dismounting of cooling fan; When carrying out cooling fan installation, the left end of three pull bars is screwed in rotating shaft, subsequently three of pressing plate inside screws are through on corresponding pull bar, continue the nut tightening three pull bar right-hand members respectively, pressing plate is by thrust-neutral, pass to cooling fan evenly, achieve the installation of cooling fan, overcome the dismounting of existing wind-driven generator cooling fan and there is easy damaged fan, inefficiency and the serious problem of potential safety hazard.
Reasonable in design of the present invention is reliable, thoroughly solve the problem of the generator failure hidden danger because causing when removing and installing generator cooling fan, and the potential safety hazard completely eliminated because causing when using flame or Electric stove mode of heating to remove and install generator cooling fan, improve the operational efficiency of Wind turbines simultaneously.
