Embodiment Construction
[0022] As shown in the accompanying drawings, the special tools for the disassembly and assembly of the fan of the transformer cooler of the present invention include:
[0023] Bracket 14: The bracket 14 is formed by welding the frame-shaped shell 10 and the elongated angle steel 8, the frame-shaped shell 10 is made of 10# channel steel, and the frame-shaped shell 10 is fixed on the middle part of the elongated angle steel 8;
[0024] Gear shaft 1 and rotating shaft 2: installed in the frame-shaped housing 10, the helical gear 12 and the sprocket 11 are installed on the gear shaft 1, the gear shaft 1 and the rotating shaft 2 are installed perpendicular to each other, and the helical groove teeth 13 on the rotating shaft 2 It meshes with the helical gear 12. One end of the rotating shaft 2 is connected with the crank handle 6 through a snap-fit insertion method. The transmission iron chain 5 is wound on the groove of the sprocket 11, and one end of the transmission iron chai...

The invention discloses a special tool for disassembling and assembling a cooler fan of a transformer. The special tool comprises a support (14). A gear shaft (1) and a rotating shaft (2) are arranged in the middle portion of the support (14). A bevel gear (12) and a chain wheel (11) are installed on the gear shaft (1). The rotating shaft (2) is perpendicular to the gear shaft (1) and is provided with spiral groove teeth (13) meshed with the bevel gear (12). One end of the rotating shaft (2) is connected with a rocker handle (6). A transmission iron chain (5) used for lifting the fan is connected with the chain wheel (11). When the special tool for disassembling and assembling the cooler fan of the transformer is used, a worker does not need to carry the fan of 75kg manually, workload can be greatly reduced, the number of staff is reduced from five to two, the safety coefficient is greatly improved, the risks that the staff are injured, sprained and crushed are greatly reduced, and meanwhile working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of tool manufacturing, in particular to a special tool for disassembling and assembling a cooling fan of a transformer. Background technique [0002] At present, when dealing with the abnormality of the fan of the transformer, the fan needs to be disassembled from the heat sink before the fan motor can be repaired. During the work, 5 people are required to cooperate to carry the transformer fan weighing 75kg from the heat sink to the ground. The narrow working surface is easy to be bruised, sprained, crushed, and cause personal injury. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a special tool for disassembling and assembling the fan of the transformer cooler, which is convenient for the operator to maintain the fan motor, and the safety factor and work efficiency of the operator are greatly improved. [0004] The present invention solves th...
