Description

Technical Field

[0001] The invention relates to the technical field of slip rings, in particular to a fan slip ring disassembly device. Background Art

[0002] At present, the connection between the Kiteng E-type slip ring and the slip ring base is a hexagon socket bolt connection. This connection form has a simple structure and is easy to disassemble and install. However, due to the heavy weight of the Kiteng E-type slip ring body, it is difficult to achieve single-person disassembly and installation during the disassembly and assembly process. In addition, it is difficult to align the hexagon socket screw hole at one time during the installation process, and the hexagon socket bolt is prone to being screwed or not screwed firmly during the actual installation process. In the long run, after the slip ring has been disassembled and assembled many times, the hexagon socket bolt will not be able to achieve a reliable connection between the slip ring and the slip ring base.

[0013] The above technical solution of the present invention has the following beneficial technical effects:

[0014] 1. When the slip ring needs to be disassembled, screw the first nut into the upper end of the positioning rod until the positioning rod abuts against the upper surface of the base and the second nut abuts against the lower surface of the rectangular plate, and then make the lower end of the first nut abut against the upper surface of the slip ring to complete the positioning of the slip ring.

[0015] 2. Screw the upper ends of the three hollow rods into the threaded holes, and allow the sliding rod to slide freely in the hollow rods. At this time, the fixed block is against the upper end of the base. At the same time, screw the threaded handle into one of the through grooves, and allow the three fixed blocks to be against the upper surface of the base, that is, fix the rectangular plate, which is convenient for aligning the slip ring and installing and disassembling it.
