Trimming mechanical arm

Abstract

The invention discloses a trimming mechanical arm. The trimming mechanical arm comprises an insulating rod, a shearing tool, a pulling rope and an insulating handle, wherein the shearing tool comprises a moveable blade, a fixed blade and a rotating shaft I; the moveable blade is hinged to the fixed blade; the cutting edges of the moveable blade and the fixed blade are bent in an arc shape; the cutting edge end of the moveable blade is longer than that of the fixed blade; a reset spring is arranged between shearing handles of the moveable blade and the fixed blade; an axial channel is formed in the insulating rod; the shearing handle of the fixed blade is fixed at the top end of the insulating rod and is provided with a through hole communicating with the axial channel; one end of the pulling rope is connected with the insulating handle, and the other end of the pulling rope penetrates through the axial channel and the through hole to be connected with the shearing handle of the moveable blade; and the pulling rope penetrates through the reset spring. The trimming mechanical arm enables a worker to stand on the ground to trim trees which influence an electric transmission line under the condition of no outage, eliminates the potential hazard of the trees on the electric transmission line, guarantees the stability of power supply, improves the operating safety and reduces the labor intensity of the worker.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a pruning manipulator. Background technique [0002] The traditional tree pruning method is to use a long pole with iron hooks to trim smaller trees. For larger trees, the staff use ladders, foot buckles and other climbing tools to go up the tree, and then use hand saws, axes or chainsaws. to trim. Because some trees are too close to the wires, when the staff go up and trim the trees, they need to cut off the power of the lines in advance, which affects the normal power consumption of users. It is very dangerous to trim trees according to these methods. During the work, live lines, falling from a height, insect bites, and falling branches may cause injury to the staff. And work intensity is very big, and work efficiency is very low. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a pruning manipulator, whic...

Because some trees are too close to the wire, when the staff go up the tree to trim, they need to cut off the power of the line in advance, which affects the normal power consumption of users

It is extremely dangerous to trim trees according to these methods. During work, live lines, falling from high altitudes, insect bites, and falling branches may cause injury to workers.

Moreover, the work intensity is very high and the work efficiency is very low
