Embodiment Construction

[0012] The present invention is further described below in conjunction with embodiment and accompanying drawing.

[0013] see figure 1 , the ladder 1 as the base in the insulating composite ladder adopted by the present invention includes a support 1a and a crossbeam 1d, the connection structure of the support 1a and the crossbeam 1d is the same as that of a common ladder, and the upper ends of the two supports 1a of the ladder 1 have jacks 1c. The quantity of ladder 1 is one section.

[0014] see figure 2 , other ladders 5 in the insulating combined ladder that the present invention adopts include support 5a and crossbeam 5d, and the connection structure of support 5a and crossbeam 5d is also identical with common ladder, and two support 5a upper ends of ladder 5 have socket 5c, and ladder 5 The lower ends of the two brackets 5a are connected with pins 5f, and the number of ladders 5 is more than two, generally 5-6.

[0015] Ladder 1 and ladder 5 are made of insulating ep...

Abstract

The combined erecting method of the insulated composite ladder mainly includes the following steps: firstly plugging one ladder as the base with the other 1 to 2 ladders in sequence to make it erect and fix it by connecting the waves and wind ropes between each ladder and the ground, Then connect the required sections of ladders in turn and connect the waves and wind ropes between each section of the ladders and the ground to fix them. The method of the invention is reasonable, the erection is stable, and its use can realize the elimination of the overhead ground wire under the condition that the line is electrified.

Description

technical field [0001] The invention relates to a method for erecting a ladder, in particular to a method for erecting an insulating composite ladder used in maintenance operations in the power supply industry. Background technique [0002] The power transmission line erected by the power supply company has been in operation for a long time, and the phenomenon of cable breakage will occur from time to time. In particular, the 110-220KV power transmission line has been in operation for a period of time, and its overhead steel strand ground wire is affected by various environments, and strand breakage may occur from time to time. Since there is currently no ideal ladder for climbing at high altitudes, when there is a broken strand of the overhead steel strand ground wire in the 110-220KV power transmission line and needs to be bound, the line can only be powered off first, and the overhead steel strand ground wire needs to be bound. The line is dropped to the ground for bindi...
