Description

Tree felling traction device
Technical Field
The utility model relates to a draw gear field, more specifically relates to a trees traction device that fells.
Background
A large number of fast forests are usually planted below or near a line corridor of a 10kV medium-voltage line, and the growth speed of trees is high. In order to ensure the safe distance between the wire and the tree, the tree obstacle removing work is required to be frequently carried out in the routine line maintenance. The reality is because some staff do not carry out effective control to the direction that trees fell down, fall easily when trees fell and arouse the short circuit tripping operation on the circuit, and it is very big to the safety and stability operation influence of circuit. When trees are felled, in order to prevent secondary damage to wires, residential houses, cash crops, field constructors and the like when the trees fall, the falling direction of the trees needs to be controlled.
The existing processing mode for controlling the inversion of felled trees comprises the following steps:
the first method is as follows: and (4) carrying out bare-handed assistance. One person fell trees, and the other person pushes trees in the opposite direction of the live line by hand, so that the tree can be directionally toppled over after the bottom end of the tree is cut off, and short circuit tripping between 10kV medium-voltage lines caused by smashing the trees on the lead wire is prevented.
The second method comprises the following steps: rope assistance. Utilize the fixed trees of waiting to fell of rope, two staff can directionally empty after making the trees bottom cut off through dragging two fag ends of dragging the rope, prevent that wire and trees of empting from discharging because the clearance is not enough.
The third method comprises the following steps: the sickle with long handle is used for assistance. One person fell the trees, and another person uses the long handle sickle to hook the trees on the tree dumping path, pulls the trees to this direction of operating personnel, makes the trees to be fell far away from the live line.
In practical application, the existing processing mode for controlling the inversion of felled trees has the following disadvantages:
the first problem is that: the stressed contact is unreliable and is easy to lose control. When the trees are felled manually, the trees are easy to rebound and topple over due to the fact that the hook rings of the trees are contacted with the tree stems to slip or the stress points are below the gravity center, and the trees are mistakenly toppled on a line, so that electric shock events are caused.
The second problem is that: the pouring path is unsafe and easy to be accidentally injured. In the process of cutting trees, the existing auxiliary mode is easy to appear: 1. the staff is close to the cutting knife saw distance, is easily taken place by the accidental injury incident. 2. The action point of the personnel pushing the trees is close to the bottom of the trees, and the action effect is not obvious. 3. The trees easily injure surrounding people when toppling over.
The third problem is that: the insulating property is not satisfied, and the electric shock is easy. When the existing tool is used, the insulating property of the operating handle of the existing tool cannot effectively protect the human body. Because the 10kV medium-voltage line is maintained, when trees fall on the wire due to misoperation, current is harmful to human bodies through the trees and the tree felling traction tool. Therefore, the tool operation handle is required to have excellent insulating property.
The fourth problem is that: the trees to be cut are fixed by the ropes, so that the trees are easy to fatigue. Before cutting down the tree, a ladder is needed to tie the rope on the tree. The direction of the tree needs to be controlled by pulling the rope by a plurality of persons. And after the trees are cut, the binding ropes need to be untied and arranged. The physical strength of the personnel is much; after the tree falls to the ground, if the rope is pressed, additional workload is added.
Therefore, it is an urgent need to solve the above-mentioned problems by developing a tree felling traction tool for insulating and isolating trees from charged bodies and safely controlling the direction of the trees.
