Description

Rocker type electric sawing machine

technical field

The utility model relates to a tree pruning tool in an overhead line channel of power distribution, in particular to a rocker-arm type electric sawing machine.

Background technique

All kinds of trees growing in the distribution overhead line channel have a great influence and harm on the safe operation of the line, which is manifested in the following aspects: In the windy weather, the branches contact the wires intermittently, which not only causes the wires to discharge to the branches to increase the power loss, but also It will accelerate the ignition and wear of the wires, and even cause the accident of broken wires and poles; when the branches touch a certain phase wire of the distribution overhead line, it will cause the occurrence of the overcurrent signal of the line. If it is affected by wet weather or rain, the branches Instantly changing from a semiconductor to a conductor will cause a single-phase grounding fault trip of the line, causing a power outage on the line; Power outages; line tripping and power outages caused by various trees growing in distribution line channels may cause voltage loss in substations; tree body conduction may cause electric shock casualties of people and animals; the impact is not only on the safe operation of the power grid and the safety of power companies Economic benefits, more seriously, affect the safe and reliable power supply of cities and local economic development, and seriously threaten the safety of power supply and utilization of enterprises, institutions and residents. Therefore, pruning trees has become an important part of the operation and maintenance of power companies.

At present, when pruning trees in the channel of the distribution line, a hand-held unpowered traditional hand saw is usually used, or a mode in which a powered pull rod is used to cooperate with a chain saw is used. When using a hand-held saw, the labor intensity is high and the work efficiency is low; while the chain saw is heavy and bulky, and the operator has to carry a load, move it repeatedly, and it is very inconvenient to use; At the same time, the insulation performance of the chain saw cannot meet the safety production regulations. At the same time, the chain saw also has disadvantages such as high equipment investment and use costs, cumbersome maintenance, small working radius, loud noise, and environmental pollution.

The operation methods of the above two tools are limited in terms of height and radius of operation, and both require the use of ladders or bucket trucks for climbing operations, which not only seriously affects the progress of tree pruning, but also increases the risk of operators falling from high altitudes. Moreover, the bucket arm truck is bulky and has dead angles in its work, occupying the road, bringing safety hazards to passing pedestrians and vehicles, and also increasing the maintenance cost of power distribution lines. For the problems referred to above, research and develop a kind of novel tree pruning tool and become the top priority of electric power enterprise.
