Further improvement of the utility model is: a side setting of the corresponding chucking device in described Ti Shen bottom is hinged on two support arms that ladder is set foot on, the near-end connecting cross beams that the corresponding ladder of two support arms is stepped on, the far-end that two corresponding ladders of support arm are stepped on connects soft support.
Further improvement of the utility model is: described terraced body, geometrical clamp, live splint and support arm are made by epoxy resin material.
Further improvement of the utility model is: the length of described terraced body is 1.0~1.1 meters, and width is 0.2~0.25 meter.
Further improvement of the utility model is: described in be installed 2/3 circular arc in hole be positioned at geometrical clamp one side, 1/3 circular arc is positioned at live splint one side.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
The utility model is by the versatility of the connected mode of synthetic insulator and shaft tower, and the bulb ring that ladder stand is fixed on to synthetic insulator connects on gold utensil, meets the requirement of versatility.By designing geometrical clamp and the live splint of mutual fastening, the upper end of ladder stand is fixed on bulb ring, adopts pin to fix, be convenient to dismounting.
The utility model arranges support arm in the bottom of ladder stand, and synthetic insulator can be blocked in the lower end of ladder stand, is convenient to fixedly ladder stand.And soft support is used in the position contacting with synthetic insulator, for example rope, prevents that the support arm of hard from damaging synthetic insulator, has played support, has protected synthetic double action.
Ladder length and the reasonable wide of the utility model design, the composite insulation substring using due to this work area 110kV transmission line is FXBW-110/100 type, every long is 1.340 meters, after linking with gold utensil, wire reaches 1.6 meters to the distance of cross-arm, the height that operating personnel upwards takes a step is generally 0.5 meter, according to the connected mode of shaft tower and synthetic insulator, the length of ladder stand is decided to be to 1.0~1.1 meters, operating personnel only need be pedaled and step on two step ladders and just can arrive above cross-arm like this.
The ladder stand of the utility model design epoxy resin material, the common used material of Zhe Shizhe work area live line working, staff is very familiar to its performance, its have lightweight (weight only for iron 1/3rd), be convenient to processing, the advantage such as tensile strength is high, corrosion-resistant.
The utility model in geometrical clamp part, is convenient to most of designed arc-shaped appearance in the hole that is installed to fix, safe and reliable.
To sum up, the utlity model has highly versatile, rational in infrastructure, safe and reliable, be easy to carry, advantage for convenience detach.
