Embodiment 1

[0041] In this embodiment 1, if figure 1 , the running mechanism of the present invention is symmetrically arranged left and right, and the right side is used as an example for illustration. The traveling mechanism includes a roller set, which is composed of a first roller 1 and a second roller 2, and a gap is formed between them, and the gap is used to pass through high-voltage electric wires. The purpose is to use the first roller 1 and the second roller 2 to Squeeze the high-voltage wires, hang and fix the traveling mechanism as a whole on the high-voltage wires.

[0042] In this embodiment, in order to further optimize the extrusion and fixing effects of the first roller 1 and the second roller 2 on the high-voltage wires, see figure 1 , arc-shaped grooves are set on the extrusion peripheral surfaces of the first roller 1 and the second roller 2, so that the high-voltage wires can be partially embedded in the arc-shaped grooves, and the first roller 1 and the second rolle...

Embodiment 2

[0052] Compared with Embodiment 1, this embodiment is different in that: in this embodiment, the two main transmission wheels of the biaxial motor and the two corresponding slave transmission wheels of the first roller are transmitted through the track structure; the second power It is also driven by crawler belt structure between the running wheel 17 of the device and the outer sleeve 12 .

Abstract

The invention discloses a detection apparatus for surface defects of a high-voltage power line. The detection apparatus comprises a running gear and a detection unit for detecting surface defects of the high-voltage power line, wherein the detection unit is installed on the running gear; the running gear comprises a pedestal, a roller train and a first power unit; the pedestal comprises a first side plate, a second side plate and a base plate, and the first side plate and the second side plate are mounted on the base plate; the roller train comprises a first roller and a second roller, and a gap for clamping the high-voltage power line is formed between the first roller and the second roller; the first roller is installed between the first side plate and the second side plate; the second roller is mounted on an elevator mechanism controlling elevation of the second roller; the elevator mechanism is mounted on the pedestal; and the first power unit drives rotation of the first roller and is mounted on the pedestal. The detection apparatus has the beneficial effects that detection personnel can visually observe the status of each position of the high-voltage power line and accurately determine the specific positions of defect points on the high-voltage power line.

Description

technical field [0001] The invention belongs to the field of high-voltage wire surface detection machinery, and in particular relates to a high-voltage wire surface defect detection device. Background technique [0002] Long-distance transmission of high-voltage electric energy in the field requires the use of high-voltage wires, which are suspended through iron towers. Because the distance between the iron towers is relatively long, the large-span high-voltage wires between the iron towers are prone to repeated pulling and twisting under harsh field conditions, resulting in local tearing on the surface of the high-voltage wires. If not found and repaired in time , Eventually causing high-voltage wires to break unexpectedly, power supply accidents occur, affecting residents and industrial electricity consumption, and causing harm to local animals and plants on the ground, and even pedestrians. [0003] At present, the early warning of defects in high-voltage wires is mainly...
