Automatic deicing robot for power transmission lines

Abstract

The invention relates to a robot for the automatic deicing of a transmission line. In the invention, a first walking box and a second walking box are connected through a second screw and nut mechanism; a screw in the second screw and nut mechanism is installed on the first walking box; the lower end of a clamping device is connected with a first screw and nut mechanism through screw threads; the first walking box is connected with a first lifting arm device through a rotating device capable of enabling a device installed on the first lifting arm device to rotate at a certain angle; the secondwalking box is connected with a second lifting arm device through the rotating device capable of enabling the device installed on the second lifting arm device to rotate at a certain angle; deicing devices and walking devices for driving the whole device to walk are arranged on the first lifting arm device and the second lifting arm device; the first lifting arm device and the second lifting arm device are arranged at the two ends of the whole walking box; and the clamping device is arranged between the first lifting arm device and the second lifting arm device. The robot for the automatic deicing of the transmission line provided by the invention can reliably realize the deicing on a high voltage transmission line and can be convenient and reliable to clear obstacles.

Description

technical field [0001] The invention relates to a deicing device for a high-voltage transmission line, in particular to an automatic deicing robot for a high-voltage transmission line. Background technique [0002] With the rapid development of my country's economy, more and more ultra-high-voltage large-capacity transmission lines are built, and the geographical environment that the line corridor passes through is more complicated, such as passing through large-scale reservoirs, lakes and mountains, which brings many difficulties to line maintenance. There are about 270,000 kilometers of 500Vk ultra-high voltage transmission lines in my country. In order to ensure their safe and reliable operation, regular inspection and maintenance are very necessary. [0003] In severe winter and early spring, rime and rime often appear in the Yunnan-Guizhou Plateau, Sichuan-Shaanxi area, and the two lakes in my country, causing overhead transmission lines to be covered with ice, causing ...

Problems solved by technology

[0005]The technical problem that is difficult to solve in the existing de-icing device is to overcome obstacles, that is, how to make the device cross the barriers such as anti-vibration hammers, wire clips and insulators on the high-voltage transmission line and has a certain climbing ability

[0006]ZL201010128239.9 discloses a "robot for automatic deicing along overhead high-voltage transmission lines", which can realize the task of deicing on high-voltage transmission lines, but the existing problems There is a problem of shifting the center of gravity when crossing obstacles, and the obstacle crossing is not reliable enough

[0007]ZL200910301757.3 discloses an "overhead transmission line deicing device", which adopts the structure of the telescopic arm and the clamping device to achieve obstacle surmounting. The existing problem is that Since the clamping device is located at both ends, the structural redundancy increases the weight, and the ice and snow on the high-voltage transmission line at one end have not been cleared, the clamping action of the clamping device is difficult, which may cause the failure of the obstacle; if the single-base structure is adopted, then The length of the body needs to be longer in order to ensure a sufficient stroke, which increases the volume of the device; the clamping device adopts an electromagnetic clamping method, and the clamping force is insufficient, making it unreliable to overcome obstacles
