Remote tree felling mechanical arm and using method

Abstract

The invention provides a remote tree felling mechanical arm and a using method. The remote tree felling mechanical arm is characterized by comprising a fixed mechanism, a first swing mechanism, a second swing mechanism, an executing mechanism, a wireless signal transmission module and a control system, wherein the first swing mechanism comprises a big arm base fixedly connected with the fixed mechanism, a big arm hinged with the big arm base on a first plane, and a first power mechanism used for controlling the big arm to swing; the second swing mechanism comprises a small arm base in slidinggroove connection with the large arm on the first plane, a small arm hinged with the small arm base on a second plane and perpendicular to the large arm, a second power mechanism used for controllingthe small arm base to slide, and a third power mechanism used for controlling the small arm to swing; and the executing mechanism is fixedly arranged at the tail end of the small arm. The whole set ofthe remote tree felling mechanical arm is good in flexibility, high in universality and high in safety, and solves the problems of a plurality of potential safety hazards on human bodies and equipment and the like for conventional felling of large trees located below live-line operation line corridors.

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.
