Power transmission line foreign matter cutting and removing device

Abstract

The invention provides a power transmission line foreign matter cutting and removing device. The device comprises a cutting mechanism for cutting a foreign matter through a rotation mode, a walking mechanism which is rotationally connected with the cutting mechanism and can move along a power transmission line, and a driving mechanism which is fixedly connected with the cutting mechanism and is used for driving the cutting mechanism to rotate. According to the power transmission line foreign matter cutting and removing device, the hanging end of a soft foreign matter is wound through the rotating cutting mechanism so that a tension force is generated at the portion, disposed between the power transmission line and the cutting mechanism, of the soft foreign matter, an effective working point is formed during the cutting of the cutting knife of the cutting mechanism, and the foreign matter is cut off by the cutting knife at the time when the cutting mechanism is rotating, thus the foreign matter is prevented from retreating along the force application direction of the cutting knife when cut by the cutting knife, the foreign matter can be effectively and rapidly cut off, the operation safety of the power transmission line is ensured, no damage is caused to the power transmission line, since the device can work under live-line conditions, the loss resulted from power-off operation can be avoided, and besides, the structure is simple and the manufacture is convenient.

Description

technical field [0001] The invention relates to an electric power maintenance device, in particular to a foreign object cutting device for a power transmission line. Background technique [0002] The transmission line is used to transmit electric energy from the place of production to the place of use, and the normal and stable operation of the transmission line is a necessary condition to ensure the stable transmission of electric energy to the place of use. However, during the use of the transmission line, it is inevitable that there will be foreign objects entangled on the transmission line, such as soft foreign objects such as plastic bags and kite strings. The existence of these foreign objects has caused great safety hazards to the transmission line, such as tripping, etc. As a result, the power cannot be transmitted continuously and stably, which has a major impact on production and life. The foreign objects mentioned above are generally relatively soft. When they ar...

However, during the use of the transmission line, it is inevitable that there will be foreign objects entangled on the transmission line, such as soft foreign objects such as plastic bags and kite strings. The existence of these foreign objects has caused great safety hazards to the transmission line, such as tripping, etc. As a result, the power cannot be continuously and stably transmitted, which has a major impact on production and life

The foreign objects mentioned above are generally relatively soft. When they are wound on the transmission line, the foreign object has only a small contact area with the transmission line, and the other parts are in a state of free suspension under normal conditions. When the traditional extraction device is used for cutting , because the foreign matter is in a suspended state, the cutting knife of the harvesting device cannot form an effective force point when it acts on the foreign matter, and the foreign matter will retreat in the direction of the cutting knife, so it is impossible to cut the foreign matter. If the cutting knife is used Cutting on the transmission line, although it can cut off foreign objects, often scratches or damages the transmission line, causing failures
