Embodiment

[0028] Such as figure 1 , 2 , shown in 3, a tension tower of a transmission line replaces the force-bearing device for the main material of the cross-arm, including a load-bearing part 8 between the wires, a temporary support cross-arm 7 and a tightening tool arranged on the pole tower 2, the bearing between the wires The two ends of the force piece are detachably connected with load-bearing extension rods 9, which are used to connect with the hanging points of the insulator strings 10 on both sides, as the supporting points for the force of the wires 1 on both sides; The temporary support cross arm is set under the cross arm 4 at the working point, which is safer when performing a series of subsequent operations. The temporary support cross arm is fixed on the main tower legs 3 on both sides of the pole tower through the fixing device 11. The fixing device includes a mounting bracket 15 and two fixing blocks 16, the mounting frame bolts are connected to the main tower legs o...

Abstract

The invention relates to maintenance devices and methods of power transmission lines, in particular to a stress device for replacing the cross arm main material of a power transmission line tension tower and an application method. The stress device comprises a between-wire load bearing part, a temporary support cross arm arranged on the tower and a tightening tool, wherein load-bearing extension rods used for being connected with insulator chains are detachably connected to two ends of the between-wire load bearing part, and a temporary-support-cross-arm reinforcing part is connected between the temporary support cross arm and the tower. The stress device is simple to operate, high in operation safety and capable of saving time and labor.

Description

technical field [0001] The invention relates to a maintenance device and method for electric power transmission lines, in particular to a force-bearing device for replacing the main material of a cross arm of a tension tower of a transmission line and a method for using it. Background technique [0002] During the operation of the existing transmission line tension pole tower, if the cross arm needs to be replaced or repaired, the wires hanging on both sides of the cross arm at the working point need to be removed and temporarily added to the tower body respectively. The tower body is connected by the main tower legs and frame composition. The process of removing the wires is cumbersome: (1) The drain wires in the middle of the wires on both sides need to be removed; (2) When the wires are temporarily hung on the side of the tower, the insulator strings should be removed or protective measures should be taken to prevent the insulator strings from (3) In order to prevent the...
