Embodiment 1
[0033] An insulating soft ladder for power cable maintenance, such as Figure 1-3 As shown, it includes two cables 1 and a plurality of pedals 2 fixed between the cables 1 . Wherein the tops of two cables 1 fix two hanging heads 3 respectively, and the hanging heads 3 include an inverted U-shaped hook 21 and a pulley 4 fixed in the inverted U-shaped hook 21 , wherein one of the hanging heads 3 sides fixes a braking device 5, Wherein hanging head 3 and braking device 5 bottoms are all provided with threaded holes, and the fixing plate of bolt is set and hanging head 3 and braking device 5 are fixed together, and pulley 4 can slide on cable 23.
[0034] The brake device 5 comprises an inverted U-shaped hook 2 6 and a fixed block 7 fixed on the rear end of the inverted U-shaped hook 2 6, wherein the inverted U-shaped hook 2 6 and the fixed block 7 are fixed by welding, and the inverted U-shaped hook 2 6 is internally arranged Vertical pressing plate 8, vertical pressing plate 8 ...
Embodiment 2
[0045] The structure of the insulating ladder for power cable maintenance in embodiment 2 is the same as that of embodiment 1, the difference is that: in the present invention, the surface of the hanger 3 and the braking device 5 are all sprayed with insulating wear-resistant paint, wherein the insulating wear-resistant paint consists of the following weight The number of parts made of raw materials: 32 parts of acrylic emulsion, 28 parts of epoxy resin, 9 parts of silica sol, 11 parts of oxalic acid polyester, 6 parts of silicon nitride, 7 parts of nano-silica, 13 parts of nitrile rubber powder , 2.5 parts of glass fiber, 3 parts of polyethylene glycol octylphenyl ether, 7 parts of sodium lignosulfonate, 18 parts of solvent and 7 parts of water.
[0046] The solvent is a mixture of ethanol and toluene at a volume ratio of 1:2.
[0047] The insulating wear-resistant coating is prepared by the following steps:
[0048] (1) Mix and disperse oxalic acid polyester, silicon nitrid...
Embodiment 3
[0052] The structure of the insulating ladder for power cable maintenance in Example 3 is the same as in Example 1. In the present invention, the surface of the hanger 3 and the brake device 5 are all sprayed with insulating and wear-resistant coatings, wherein the insulating and wear-resistant coatings are made of the following raw materials in parts by weight Ingredients: 35 parts of acrylic emulsion, 25 parts of epoxy resin, 10 parts of silica sol, 12 parts of oxalic acid polyester, 7 parts of silicon nitride, 6 parts of nano silicon dioxide, 14 parts of nitrile rubber powder, 2 parts of glass fiber , 4 parts of polyethylene glycol octyl phenyl ether, 6 parts of sodium lignosulfonate, 17 parts of solvent and 8 parts of water.
[0053] The solvent is a mixture of ethanol and toluene at a volume ratio of 1:2.
[0054] The insulating wear-resistant coating is prepared by the following steps:
[0055] (1) Mix and disperse oxalic acid polyester, silicon nitride, nano-silica, gl...
