Tool for clearing barriers around aerial cables on ground

Abstract

The invention discloses a tool for clearing barriers around aerial cables on the ground. The tool comprises an insulating rod, a cutter and a saw blade, the cutter is sickle-shaped, a meniscate first cutting blade is arranged at the top of the cutter, a second cutting blade bent inward is arranged below the cutter, an arc-shaped third cutting blade is arranged on a side edge of a front end of the cutter, a tool holder is arranged at a tail end of the cutter, the tool holder is fixed to a top end of the insulating rod, and the saw blade is fixed to the tail end of the cutter. Compared with the prior art, the tool disclosed by the invention has the functions of chopping, cutting, jacking, pulling, hooking and sawing, and requires no tree climbing aerial operation, thereby reducing the risk of electrified operation and greatly reducing the safety risk. No ladder needs to be carried, the tool is convenient to carry and is complete in functions, and an electrician can carry no other felling tools. The operation is simple and understandable, and a large amount of manpower is not required, thereby saving the labor cost. No power cut is required for close electrified branches in general. The compensation caused by cutting a whole tree resulting from that the branches cannot be cut is reduced.

Description

technical field [0001] The invention relates to a tool, in particular to a tool for clearing obstacles around high-altitude cables on the ground. Background technique [0002] Since the lines of the rural power grid are all over the mountains and fields, and the heights of the lines are different, the line channels need to be cleaned and maintained for a long time. Our maintenance and clearing work basically accounts for one-third of the working time, so I think about how to How to reduce the difficulty of obstacle removal work, how to carry out obstacle removal work in a safe, convenient and flexible manner. [0003] Usually, the general obstacle removal is to use the stairs to climb up the tree trunk to cut down the branches. Sometimes the stairs cannot be reached and the operator can only climb up directly. Some bent trees or tall trees have a very large swing arc, and there are many dead branches. And brittle branches, the safety risk of tree climbers is very high. It i...

[0003] Usually, the general obstacle removal is to use the stairs to climb up the tree trunk to cut down the branches directly. Sometimes the stairs cannot be reached and the operator can only climb up directly. Some bent trees or tall trees have a very large swing arc, and there are many dead branches. And brittle branches, the safety risk of tree climbers is very high. It is known that there are many cases of injury caused by clearing obstacles and cutting trees

In addition, it is necessary to clean up the branches near the live or contacting the wire. If there is risky operation in the live cleaning, there are usually many lush tree (bamboo) branches that the clearing personnel cannot reach the cutting position at all, especially now Ma bamboo, a shed is densely packed with several square meters or even more than 10 square meters. It is impossible to cut one of them in place.
