A fastening nut removal device with a rubber sheath and its application method

Abstract

The invention relates to a clamp nut disassembling tool, in particular to a disassembling device for a clamp nut with a rubber protective sleeve in an electric ring main unit and a cable branch box. The device is characterized in that driven gear shafts distributed in an equilateral triangle shape are arranged in a shell, three driven gears are installed on the driven gear shafts respectively and meshed with a center gear, the three driven gears are provided with convex lugs with center holes towards the outermost end of the center gear, clamping jaws with sharp corners in front ends are arranged in the center holes in the convex lugs, the walls of the convex lugs are provided with positioning screws for adjusting the extending length of the clamping jaws, and an end cover and the center gear are provided with spanner inserting holes. The device has the advantages that operation is easy, working efficiency is high, the clamp nut with the rubber protective sleeve is disassembled with no damage, a large number of electric components are omitted, and the using prospect is good.

Description

technical field [0001] The invention relates to a tool for dismantling fastening nuts, in particular to a device for dismantling fastening nuts with rubber sheaths in power ring network cabinets and cable distribution boxes and a method for using them. Background technique [0002] As we all know, after the cable elbows of the ring network cabinet and the cable distribution box are manufactured and installed, it is necessary to install a fastening nut coated with lubricating oil behind the elbow. After running for a long time, the oil between the fastening nut and the gap between the sheath condenses, and the combination of the sheath, condensed oil and the nut is very tight, and the condensed oil between the sheath and the nut is difficult to remove, so that when the plate is disassembled Hands cannot effectively contact the fastening nut. In addition, the fastening nut is made of insulating plastic material, which makes it impossible to remove or often causes damage to the...

Problems solved by technology

After running for a long time, the oil between the fastening nut and the gap between the sheath condenses, and the combination of the sheath, condensed oil and the nut is very tight, and the condensed oil between the sheath and the nut is difficult to remove, so that when the plate is disassembled Hands cannot effectively contact the fastening nut. In addition, the fastening nut is made of insulating plastic material, which makes it impossible to remove or often causes damage to the fastening nut, which makes it impossible to perform non-destructive removal. At the same time, due to the difference between the ring network cabinet and the cable distribution box As well as the different manufacturers of fastening nuts, the size and shape of fastening nuts are also different, which requires maintenance workers to carry a variety of tools, resulting in inconvenient disassembly
