Problems solved by technology

Many trees are more than 10 meters high. To trim super-high trees, only manned cranes can be used to carry out operations, which has high cost and low construction efficiency; and in some mountainous or forest areas, due to terrain conditions or because the trees in the forest are too dense , it is impossible to use manned cranes to carry out operations, causing great hidden dangers to the maintenance of transmission lines
If artificial climbing is used to trim branches, the operation risk is very high, and there is a risk of falling from a high altitude

Embodiment 1

[0036] Such as Figure 1-2 As shown, the embodiment of the present invention provides a tree felling device, including a throwing device 1 , an insulating rope 2 , a metal cutting rope 3 and a driving device 4 . One end of the insulating rope 2 is fixed to the throwing device 1, and the other end is a free end. The free end is thrown into the air through the throwing device 1 and bypasses the branches to be felled; the insulating rope 2 can guide the metal cutting rope 3 to hang on the Above the branches; both ends of the metal cutting rope 3 hanging above the branches to be felled are fixed on the driving device 4, and the driving device 4 drives the metal cutting rope 3 to generate reciprocating motion, and the cutting is completed by reciprocating friction on the branches to be cut down.

[0037] Further, a pulling hammer 21 is fixed at the front end of the insulating rope 2 . The traction hammer 21 has a relatively large weight, which is convenient for the throwing device...

Embodiment 2

[0042] In the tree-cutting device provided by the present embodiment, its throwing device 1, insulating rope 2 and metal cutting rope 3 are the same as those in the first embodiment. The difference between this embodiment and Embodiment 1 is that the frame 41 of the driving device 4 includes a first frame 411 and a second frame 412, the power mechanism 42 is fixedly connected to the first frame 411, and the tension mechanism 43 is fixedly connected to The second rack 412 . The first frame 411 and the second frame 412 are set separately, so that the metal cutting rope 3 is at a certain angle on the branch to be felled, as image 3 shown. The included angle can be 0°-180°, and the specific implementation angle can be determined according to the terrain and the shape of the working tree, and is not limited to this embodiment. Preferably, universal wheels with a parking function may be installed on the bottoms of the first frame 411 and the second frame 412 to facilitate adjustm...

Embodiment 3

[0045] The embodiment of the present invention provides a kind of tree-cutting method, uses the tree-cutting device in embodiment 1 or embodiment 2, and its specific steps include:

[0046] Step S100, use the throwing device 1 to align the insulating rope 2 above the branch to be felled and throw it; wherein, one end of the insulating rope 2 is fixed to the throwing device 1, and the other end is a free end, and the free end is fixed with a traction hammer 21 ;

[0047] Step S200, after the insulating rope 2 bypasses the branch to be felled, connect one end of the insulating rope 2 to the metal cutting rope 3; this end can be the free end of the insulating rope 2, and the end of the insulating rope 2 with the traction hammer 21 can be used Connect the metal cutting rope 3; or this end can be the fixed end of the insulating rope 2, and the fixed end can be removed from the throwing device 1 and connected to the metal cutting rope 3;

[0048] Step S300, using the insulating rop...

Abstract

The invention belongs to the technical field of tree cutting operation, and particularly relates to a tree cutting device and a tree cutting method using the same. The tree cutting device comprises athrowing device, a metal cutting rope, an insulating rope and a driving device; one end of the insulating rope is fixed to the throwing device, and the insulating rope is used for guiding the metal cutting rope to be hung above to-be-cut branches and trunks; and the two ends of the metal cutting rope are fixed to the driving device, and the driving device drives the metal cutting rope to reciprocate. According to the tree cutting method provided by the invention, the free end of the insulating rope is aligned to the to-be-cut branches and trunks through the throwing device for throwing; afterthe insulating rope is wound around upper parts of the to-be-cut branches and trunks, the metal cutting rope is guided to be suspended above the to-be-cut branches and trunks; and then the driving device drives the metal cutting rope to rub the to-be-cut branches and trunks back and forth to finish cutting. A manned crane or manual climbing is avoided in the tree cutting process, limitation of theoperation environment and the tree variety is avoided, electric cutting is achieved, manual operation is not needed, and high efficiency and reliability are achieved; and the operation cost is low, and personal high-altitude falling risks are avoided.

Description

technical field [0001] The invention relates to the technical field of tree-cutting operations, in particular to a tree-cutting device and a tree-cutting method using the device. Background technique [0002] In the operation and maintenance of transmission lines, it is often necessary to cut down and trim super-high trees to avoid the occurrence of line tripping accidents caused by trees touching high-voltage wires. However, when cutting and pruning trees, because the trees are state-owned or privately owned, usually only pruning can be carried out, and felling is not allowed. Many trees are more than 10 meters high. To trim super-high trees, manned cranes can only be used to carry out operations, which has high cost and low construction efficiency; and in some mountainous or forest areas, due to terrain conditions or because the trees in the forest are too dense , It is impossible to use a manned crane to carry out operations, causing great hidden dangers to the maintenan...
