High-altitude branch saw

Abstract

The invention discloses a high-altitude branch saw which solves the technical problem that an existing obstacle removing device of a network distribution line is poor in reliability. The high-altitude branch saw comprises a fixing frame; a roll shaft is arranged on the fixing frame; cutting teeth or / and scrapers or / and cutters are arranged on the peripheral face of the roll shaft; a hydraulic motor for driving the roll shaft is arranged on the fixing frame; the fixing frame is connected with a crane arm; the hydraulic motor is connected with a hydraulic pump; the hydraulic pump is arranged on a crane; and an oil tank and a hydraulic control system which are connected with the hydraulic pump and the hydraulic motor are arranged on the crane. The high-altitude branch saw is suitable for the high-altitude environment, and the hydraulic motor is adopted to drive an obstacle clearing mechanism in a hob form, so that the risk that a traditional chain saw is prone to being clamped can be effectively avoided, the obstacle clearing effect is good, and branches of different sizes can be smashed between the roller shaft and the fixing frame. The hydraulic motor is adopted to drive the roller shaft, so that a torque is large, and dead halt caused by clamping stagnation is avoided; and a hydraulic pipeline and a control circuit are hidden in the fixing frame, so that the safety performance is fully guaranteed.

Description

technical field [0001] The invention relates to the technical field of obstacle removal for distribution network lines, in particular to a high-altitude branch saw. Background technique [0002] At present, urban distribution network lines are basically erected along urban roads, and most lines extend through the woods. Although most of the overhead lines use insulated wires, because most of them pass through the woods, the insulation skin of the insulated wires is often worn by branches during operation, causing discharge ignition and disconnection faults, especially in special weather such as heavy rain and strong wind. problems are particularly prominent. After analyzing the tripping and disconnection faults of 10kV distribution network lines in many local and city companies, it was found that more than 90% of the insulated wire disconnections were caused by tree barriers. In severe convective weather, line tripping faults often occur, which greatly reduces the reliabil...
