Problems solved by technology

However, due to the fact that the layout of the wires of the double-circuit line on the same pole is different from that of the single-circuit line, the existing pole support tools cannot simultaneously fix, spread or pull the four wires on the lower layer of the double-circuit line erected on the same pole.

Embodiment 1

[0030] a kind of like Figure 1-3 The shown schematic diagram of the double-circuit line conductor support bar on the same pole includes an upper support bar 1, a lower support bar 2, insulating straps for the braces, and insulating straps for lifting. The upper strut is composed of two sections, and the bolts are used to fix the pull-out structure between the sections. Two horizontally distributed impact chucks 5 are arranged at both ends of the upper strut; The lower strut is composed of two sections, and the segments are connected by an aluminum alloy sleeve type screw rod 6, and four vertical impact chucks are distributed on the lower strut. Ring-type lifting points 7 are arranged at the impact chucks of the upper and lower struts. The lifting insulating sling is a round sling 4, and a gravity locking hook 8 is arranged at the end of the sling. The insulating suspenders connecting the struts are flat suspenders 3 with adjustable length, and buckles 9 that can be matched ...

Abstract

The invention discloses a lead wire brace rod for double-circuit lines on the same pole, comprising an upper brace rod, a lower brace rod, an isolative hanging strip for connecting the brace rods and an isolative hanging strip for lifting, wherein the upper brace rod and the lower brace rod are respectively provided with two or more lead wire fixing clamps, and each fixing clamp is provided with a hanging point; two end parts of the isolative hanging strip for connecting the brace rods are provided with hasps for clasping the isolative hanging strip onto the hanging points of the upper brace rod and the lower brace rod; and the end part of the isolative hanging strip for lifting is provided with a lifting hook. The lead wire brace rod has the advantages of reasonable structure, flexibility in mounting and dismounting, and convenience in carrying. Particularly, the application of an aluminum alloy sleeve-type lead screw favorably meets the requirements on stable and horizontal movementof a plurality of lower-layer lead wires. The lead wires are fixed by adopting impacting type chucks, and a horizontal distribution mode and a vertical distribution mode are respectively adopted according to the arrangement patterns, the quantity and the environmental conditions of the lead wires to be fixed, therefore, the lead wire brace rod is extremely convenient for the operators for on-sitemounting and dismounting.

Description

technical field [0001] The invention relates to a tool for live work, in particular to a support rod for a double-circuit line conductor on the same rod. Background technique [0002] With the rapid development of the national economy, the demand for electricity consumption in urban and rural areas has grown rapidly, and there are frequent cases of T-connection of new equipment after the 10kV power supply feeder is charged and the pole is erected. Usually, the working method of live poles for single-circuit lines is: after insulating and shielding the live wires in a certain range above the pole pit of Xinli electric poles, use tools such as insulating rods to spread the phase wires on both sides of the lower layer and lift the middle phase wires of the upper layer. After conducting the wire, carry out the erection of the new electric pole. The purpose is to ensure that components such as the shaft or the cross arm of the new pole do not touch the charged body during the er...
