Embodiment Construction

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

[0013] see figure 1 The ladder 1 used as the base in the insulating combination ladder provided by the present invention includes a bracket 1a and a crossbeam 1d, the connection structure of the bracket 1a and the beam 1d is the same as that of a common ladder, and the upper ends of the two brackets 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 provided by the present invention include a bracket 5a and a crossbeam 5d, and the connecting structure of the bracket 5a and the crossbeam 5d is also the same as that of a common ladder. The lower ends of the two brackets 5a are connected with pins 5f, and the pins 5f are integrated with the brackets 5a. The quantity of ladder 5 is equipped with more than two sections, generally equipped with 5-6 sections.

Abstract

The present invention discloses an insulation combinatorial ladder, which is composed by more than two segments of ladders, upper ends of two supports of one segment ladder that used as base plate have plug jack, lower ends of two supports of the other ladders connect with base pin and upper end has plug jack, external side of two upper supports of each ladder fixed with a connecting ring. The combinatorial mount method of the insulation combinatorial ladder mainly includes the following steps: connect the ladder taken as base plate with other 1-2 ladders in series by inserting to make it stands and fixes by connecting each ladder and ground with staying wire, then links each necessary ladder in series and fixes each ladder and ground through staying wire. The present invention has reasonable structure and stable construction, and can realize eliminating defects to overhead ground wire when wires electrified.

Description

technical field [0001] The invention relates to a ladder and its erecting method, in particular to an insulated composite ladder and its erecting method used in high-altitude operations in the power supply industry. Background technique [0002] After long-term operation of the power transmission line erected by the power supply company, the conductor and ground wires will be broken 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 wires are dropped to the ground for binding a...
