Mechanical arm for remote live tree cutting and application method

Abstract

The invention provides a mechanical arm for remote live tree cutting and an application method. The mechanical arm is characterized by comprising a fixing mechanism, a first swing mechanism, a secondswing mechanism, an execution mechanism, a wireless signal transmission module and a control system, wherein the first swing mechanism comprises a large arm base fixedly connected with the fixing mechanism, a large arm hinged with the large arm base in a first plane, and a first power mechanism for controlling the large arm to swing; the second swing mechanism comprises a small arm base, a small arm, a second power mechanism for controlling the small arm base to slide and a third power mechanism for controlling the small arm to swing; the small arm base is connected with the large arm througha sliding chute in the first plane; the small arm is hinged with the small arm base in a second plane and is perpendicular to the large arm; and the execution mechanism is fixed at the tail end of thesmall arm. The complete set of result is good in flexibility, high in versatility and high in safety, and potential safety hazards to persons and equipment and other problems in cutting of large trees below a live running line corridor at present are avoided.

Description

technical field [0001] The invention belongs to the fields of tree felling technology and electric facility maintenance and obstacle removal, and in particular relates to a mechanical arm and a use method for remote live felling of large trees in power line corridors. Background technique [0002] In the maintenance of power facilities, there are often large trees that need to be felled and cleared in the line corridor. At present, all tree felling is carried out by hand at close range. Loggers must not only abide by the safe use of chainsaws during the felling process At the same time, it is necessary to judge the timing of tree fall and the timing of safe evacuation. If you make a mistake in judging the direction of falling when cutting down a large tree close to the live wire or if you do not evacuate in time, it is very likely to cause personal electric shock or other dangerous situations. In addition, for large trees, chainsaws (chainsaws) are used to fell them manuall...

AI Technical Summary

Problems solved by technology

If you make a mistake in judging the fall direction or fail to evacuate people in time when cutting down a large tree close to the live wire, it is very likely to cause personal electric shock or other dangerous situations

In addition, for large trees, chainsaws (chainsaws) are used to fell them manually, and the saw guide plate and saw chain are often crushed and bounced by fallen trees, which may also easily cause injuries to fellers.
