Problems solved by technology
Due to the heavy weight of the supporting porcelain bottle, for example, the weight of the supporting porcelain bottle on one side of the GW5 anti-pollution isolating switch is 75KG, and the weight of supporting the porcelain bottle on the side of the ordinary isolating switch is 52KG. If a crane is used to assist dismantling, it is also quite difficult to implement due to site restrictions and the scope of power outages

Embodiment Construction
[0020] see figure 1 , figure 2 , The isolating switch bearing 1-2 is positioned at the bottom of the support porcelain bottle 1-1. When the bearing 1-2 is overhauled and maintained, at first the support porcelain bottle 1-1 is disassembled to separate the support porcelain bottle 1-1 from the bearing 1-2.
[0021] see image 3 , Figure 4 , Figure 5 , the present invention includes a lifting bracket 2-1, a beam 2-2, a double-hook ratchet rope tightener 2-3 and a lifting rope 2-4, and the lifting bracket 2-1 is symmetrically arranged on the single-phase isolating switch 1 to support the porcelain bottle 1 -1 on both sides, it is fixedly installed on the base fixed channel steel 3 of the isolating switch, the beam 2-2 is installed on the top of the two lifting brackets 2-1, and the double hook ratchet rope tightener 2-3 is two The ends are respectively connected with the crossbeam 2-2 and the suspension rope 2-4 which is set on the outside of the supporting porcelain bottl...

The invention provides a hanging bracket special for electric power disconnecting switch overhauling, and aims at solving the separation problem of a disconnecting switch support porcelain bottle and a bearing. The hanging bracket comprises hoisting supports, a beam, a double hook ratchet wheel euphroe and a hanging rope, wherein the hoisting supports are symmetrically arranged on two sides of a single phase disconnecting switch support porcelain bottle and are fixedly mounted on foundation fixing channel steel of a disconnecting switch, the beam is mounted at the top end of the two hoisting supports, and two ends of the double hook ratchet wheel euphroe are respectively connected with the beam and the handing rope mounted outside the support porcelain bottle in a sleeved mode. The hanging bracket for the electric power disconnecting switch overhauling has the advantages of being simple in structure, convenient to operate, and free from being limited by fields, enabling the support porcelain bottle to be separated from the bearing with ease, not only ensuring that overhauling and maintenance work of the bearing is carried out smoothly, but also lightening labor intensity of manipulators, eliminating potential safety hazards, and improving work efficiency.
Description
technical field [0001] The invention relates to a special tool for overhauling a power isolating switch, in particular to a special hanger suitable for overhauling a GW5 type isolating switch, and belongs to the technical field of power generation, transformation or distribution. Background technique [0002] After the substation isolating switch has been in operation for a long time, the rotating parts will rust and die, which makes the operation of the isolating switch very difficult. Therefore, the bearings of the isolating switch need to be inspected and maintained regularly. Generally, the bearing of the isolating switch is located at the bottom of the supporting porcelain bottle. When the bearing is overhauled, the supporting porcelain bottle must be disassembled first (refer to the attached figure 1 , attached figure 2 ). Due to the heavy weight of the supporting porcelain bottle, for example, the weight of the supporting porcelain bottle on one side of the GW5 ant...
