Problems solved by technology

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

Embodiment 1

[0017] As shown in the figure: the live pruning device of the present embodiment includes an insulating rod, a scissors located on the insulating rod, a traction rope 4, an insulating handle 5 and a saw blade 61; The fixed blade 22 and the rotating shaft I23 hinged by the blade 21; the cutting edges of the movable blade 21 and the fixed blade 22 are curved in an arc shape, and the length of the blade end of the movable blade 21 is greater than the length of the blade end of the fixed blade 22; 21 and the scissor handle of the fixed blade 22 are provided with a return spring 3 for providing a reset force; the insulating rod is provided with an axial channel 1a, and the scissor handle of the fixed blade 22 is fixed on the top of the insulating rod and set There is a through hole 22a communicating with the axial passage 1a, one end of the traction rope 4 is connected with the insulating handle 5, and the other end is connected with the scissor handle of the movable blade 21 after ...

Embodiment 2

[0023] The electrified pruning device of this embodiment is structurally the same as that of the electrified pruning device in Embodiment 1, the only difference being the composition of the glass fiber material; in this embodiment, the glass fiber material includes the following components in parts by weight Divide: 31 parts of quartz sand, 10 parts of limestone, 5 parts of dolomite, 1 part of boric acid, 4 parts of Glauber's salt, 2 parts of fluorite, 1 part of pyrophyllite, 9 parts of alumina, and 10 parts of silicon dioxide. The materials of the above components are melted and sintered into 20mm rods or spheres, and then heated and remelted to make finer 3-60um fibers, and then the fibers are made into super-strong fiber rods by reverse winding with a roller machine or barrel. The material has high strength. After testing, the tensile strength of a single fine fiber can reach 2840Mpa, and the elastic modulus can reach 86000Mpa, which is several times higher than that of hig...

Embodiment 3

[0025] The electrified pruning device of this embodiment is structurally the same as that of the electrified pruning device in Embodiment 1, the only difference being the composition of the glass fiber material; in this embodiment, the glass fiber material includes the following components in parts by weight Divide: 35.5 parts of quartz sand, 13.5 parts of limestone, 9.5 parts of dolomite, 3.5 parts of boric acid, 7 parts of Glauber's salt, 5.5 parts of fluorite, 3 parts of pyrophyllite, 12 parts of alumina, and 12 parts of silicon dioxide. The materials of the above components are melted and sintered into 20mm rods or spheres, and then heated and remelted to make finer 3-60um fibers, and then the fibers are made into super-strong fiber rods by reverse winding with a roller machine or barrel. The material has high strength. After testing, the tensile strength of a single fine fiber can reach 2985Mpa, and the elastic modulus can reach 88500Mpa, which is several times higher tha...

Abstract

The invention discloses an electrified pruning device. The electrified pruning device comprises an insulating rod, a shearing tool, a pulling rope, an insulating handle and a saw knife, wherein the shearing tool comprises a moveable blade, a stationary blade hinged with the moveable blade and a rotating shaft I; the cutting edges of the moveable blade and the stationary blade are arc-shaped bending; the length of the cutting edge end of the moveable blade is more than that of the cutting edge end of the stationary blade; a reset spring is arranged between shearing handles of the moveably blade and the stationary blade; an axial channel is formed in the insulating rod; the shearing handle of the stationary 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 is connected with the shearing handle of the moveable blade after passing through the axial channel and the through hole; and the reset spring is threaded on the pulling rope. The electrified pruning device enables a worker to stand on the ground under the condition of no power outage to prune trees which influence an electric transmission line, eliminates the potential danger of the trees on the electric transmission line, guarantees the stability of power supply, improves the operation 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 charged pruning device. 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 live pruning device, w...
