Abstract
The invention discloses a tool set for replacing a strain insulator string of a substation framework. The tool set is provided with an insulator cradle, wherein the insulator string is placed on the insulator cradle, the two ends of the insulator cradle are provided with a movable clamp (2) and a fixed clamp (3) respectively, the two sides, arranged at one end of the fixed clamp (3), of the insulator cradle are respectively provided with a ratchet lever pulley block (4), the two ratchet lever pulley blocks (4) are connected with the movable clamp (2) through a tightening rope (5), and the two ratchet lever pulley blocks (4) drive the movable clamp (2) to move through the tightening rope (5). According to the tool set, the power outage time can be greatly shortened, the labor intensity can be reduced, and the labor efficiency is improved.
Description
Technical field
The present invention relates to a kind of for changing the tool set of electric substation's framework strain insulator string.
Background technology
The old common insulator that most of 35KV and above electric substation use all needs to be replaced by pollution proof insulator, but the workload of this replacing is large, and the equipment interruption duration is short in the process of changing, higher to quality and safe requirement in construction, but due to the construction site complexity of electric substation, charging equipment is many, working range is less, and not only increased labour intensity while adopting at present the one chip jig, reduce operating efficiency, and needed when mounted time of having a power failure long.
Summary of the invention
The invention provides a kind ofly for changing the tool set of electric substation's framework strain insulator string, it not only can shorten interruption duration greatly, and can reduce labour intensity, raises labour efficiency.
The present invention has adopted following technical scheme: a kind of for changing the tool set of electric substation's framework strain insulator string, it is provided with bottle-holding rack, insulator string is placed on bottle-holding rack, be respectively equipped with movable fixture and holding clamp at the two ends of bottle-holding rack, the both sides that are positioned at holding clamp one end at bottle-holding rack are respectively equipped with the ratchet lever hoist, two ratchet lever hoists are connected with movable fixture by hauling, and two ratchet lever hoists drive the movable fixture motion by hauling.
The both sides of described bottle-holding rack are fixed metal support, are provided with some cross bars and vertical pole between two metallic supports, and cross bar and vertical pole are the insulating epoxy pipe, after cross bar is connected with metallic support with vertical pole, form the stretcher shape.Described ratchet lever hoist is 3T ratchet lever hoist.Described movable fixture is angle bar.Described holding clamp is galvanized steel bar.Described bottle-holding rack side is provided with the lifting lever, and an end of lifting lever is connected with holder, and the other end is connected with lifting tackle, is wound with insulation ropes on lifting tackle.
The present invention has following beneficial effect: the present invention adopts bottle-holding rack and ratchet lever hoist, tighten up insulator string by the ratchet lever hoist, after not stressing, insulator string more renews insulator string, so not only can change easily insulator string, reduce labour intensity, well improve the effect of efficiency of construction and fail safe, and save the workmen, can greatly shorten interruption duration simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
In Fig. 1, the present invention is a kind of for changing the tool set of electric substation's framework strain insulator string, it is provided with bottle-holding rack, the both sides of bottle-holding rack are fixed metal support 6, be provided with some cross bars 7 and vertical pole 8 between two metallic supports 6, cross bar 7 and vertical pole 8 are the insulating epoxy pipe, after being connected with metallic support 6 with vertical pole 8, cross bar 7 forms the stretcher shape, insulator string is placed on bottle-holding rack, be respectively equipped with movable fixture 2 and holding clamp 3 at the two ends of bottle-holding rack, movable fixture 2 is angle bar, holding clamp 3 is galvanized steel bar, the both sides that are positioned at holding clamp 3 one ends at bottle-holding rack are respectively equipped with ratchet lever hoist 4, ratchet lever hoist 4 is 3T ratchet lever hoist, two ratchet lever hoists 45 are connected with movable fixture 2 by hauling, two ratchet lever hoists 4 are by 5 drive movable fixture 2 motions of hauling, be provided with lifting lever 9 on the bottle-holding rack side, one end of lifting lever 9 is connected with holder 10, the other end is connected with lifting tackle 11, be wound with insulation ropes 1 on lifting tackle 11.The present invention on insulator string, installs ratchet lever hoist 4 by the bottle-holding rack colligation, tightens up ratchet lever hoist 4, and insulator string is not stressed, and promotes insulator string by the lifting tackle 11 on lifting lever 9 and goes out the insulator string more renewed after bottle-holding rack.
