Description
Technical field
The invention belongs to the construction of power transmission and transformation instrument, particularly a kind of telescopic synthetic insulator cat ladder.
Background technology
In the construction of power transmission and transformation operation; Usually need the operating personnel from carrying out upkeep operation to lead under the cross-arm; Because the vertical distance of synthetic insulator; And synthetic insulator requires and mustn't trample, and the operating personnel from carrying out upkeep operation to lead under the cross-arm, brings great inconvenience to job execution with regard to difficult like this.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of volume little, in light weight, tear the telescopic easily synthetic insulator cat ladder of extension open.
The technical scheme that technical solution problem of the present invention adopts is: telescopic synthetic insulator cat ladder comprises hook, draw ring, clamp nut; Be characterized in that take-up device connecting rod right-hand member head is fixedly connected draw ring; Intermediate sleeve dress adapter sleeve; It is spacing that clamp nut is housed on the adapter sleeve; Left end is fixedly connected flexible take-up device, and the left end head of take-up device is fixedly connected hook, suit inner layer sleeve, intermediate layer sleeve pipe, outer layer sleeve successively from left to right on take-up device and take-up device connecting rod; The left end head of inner layer sleeve, intermediate layer sleeve pipe, outer layer sleeve is fixedly connected internal layer ladder, intermediate layer ladder, outer ladder respectively; Spacing between inner layer sleeve and the intermediate layer ladder with the spacer pin that is inserted on the inner layer sleeve, spacing between intermediate layer sleeve pipe and the outer ladder with the spacer pin that is inserted on the sleeve pipe of intermediate layer, spacing between outer layer sleeve and the take-up device connecting rod with the guide vane end stop on the take-up device connecting rod.
The invention has the beneficial effects as follows: telescopic synthetic insulator cat ladder volume is little, in light weight; Tear open and hang convenient, fastly, the operating personnel can be made things convenient for freely from carrying out upkeep operation to lead under the cross-arm, safe and reliable; Bring great convenience to job execution, improved the efficient of job execution.
Description of drawings
