Embodiment 1

[0035] Such as Figure 1 to Figure 3 As shown, the present invention provides a sliding and hanging rope for emergency dancing, which includes two frames 3, and a plurality of connecting rods 2 are arranged between the two frames 3. The connecting rods 2 are made of carbon fiber material and have a certain elastic deformation capacity. , a number of T-shaped rolling elements 1 are connected in series on the connecting rod 2, and the T-shaped rolling elements 1 are rotationally connected with the connecting rod 2. The T-shaped rolling elements 1 include an outer cylinder and a stepped cylinder. Deformation capacity; and the T-shaped rolling elements 1 on each connecting rod 2 are misplaced with the T-shaped rolling elements 1 on the adjacent connecting rods 2, that is, the outer cylinder of the T-shaped rolling elements 1 on each connecting rod 2 and the corresponding The positions of the stepped cylinders of the T-shaped rolling elements 1 on the adjacent connecting rod 2 corr...

Embodiment approach

[0044] Such as Figure 4 and 5As shown, the second embodiment of the present invention, the difference between this embodiment and the first embodiment is that the rolling element 1 is a cross-shaped structure.

Abstract

The invention discloses a sliding and rolling wire hanging rope belt for emergency dance stopping, which comprises two frames, a plurality of connecting rods are arranged between the two frames, a plurality of rolling bodies are connected in series on the connecting rods, and the rolling bodies on each connecting rod and the rolling bodies on the adjacent connecting rod are arranged in a staggered manner. Sliding friction between the inhaul cable and the wire is changed into rolling friction, and the contact area between the inhaul cable and the wire is increased, so that the abrasion risk is reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of anti-galling of power transmission lines, in particular to a sliding-roller hanging cord belt for emergency anti-galling. Background technique [0002] The large vibration when the transmission line gallops will cause damage to transmission line equipment such as ground wires, pole towers, insulators, fittings, etc. In severe cases, it may even cause accidents such as tower toppling and ground wire disconnection, which seriously threatens the safety and stability of the power grid. [0003] At present, some studies have proposed an emergency stop galloping method based on cables. During temporary power outages due to galloping of transmission lines, the galloping conductors are pulled and anchored by cables to prevent large vibrations of the conductors and ensure that the cables have Live running conditions to ensure the safety of transmission lines. [0004] At present, the way to insulate the cable is ...
