Barrier-crossing mechanism of transmission line deicing robot

Abstract

The invention relates to a barrier-crossing mechanism of a transmission line deicing robot. The barrier-crossing mechanism comprises three barrier-crossing devices arranged on the front and the back. Each barrier-crossing device is formed by a lift device and a rotation device, wherein the lift device is arranged on a rotating disk of the corresponding rotation device, and the rotating disk of each corresponding rotation device is connected with a rotation motor arranged on a fixed plate so as to rotate. The top of each lift device is provided with a pulley used for clamping a transmission line and capable of rolling and running on the transmission line. The pulley is arranged on a telescoping column, and rises and descends along with the telescoping column. The telescoping column fits a screw, and the screw is connected to a lift motor through a shaft coupling. When the barrier-crossing mechanism crosses a barrier, the upward and downward linear sliding of the lift devices and the rotation of the rotation devices are conducted independently, and are coordinated and cooperated with each other, the upward and downward linear sliding enables each pulley to separate from the corresponding transmission line, and the rotation enables each pulley to pass by a barrier on a plane. Therefore, a control portion is easier, and more feasible and operational compared with control portions of other conventional barrier-crossing mechanisms.

Description

technical field

[0001] The invention relates to power line deicing, in particular to an obstacle surmounting mechanism of a power line deicing robot. Background technique

[0002] Faults caused by icing on transmission lines have always been one of the serious disasters in power systems at home and abroad. At present, the most commonly used deicing technology in China is the manual deicing method, which is labor-intensive, expensive and dangerous. There is an urgent need for methods and equipment that can replace manpower for line deicing. Deicing robots are used under this demand. born. However, one of the most difficult problems in actual use of deicing robots is obstacle surmounting. Some deicing robots already have the function of surmounting obstacles, but they have higher requirements for distance and angle during actual movement, resulting in higher cost and even difficult implementation. Therefore, The obstacle surmounting mechanism of the deicing robot still needs...
