Description

Technical Field

[0001] The present application relates to the field of tree branch pruning, and in particular to an insulated high-branch saw for clearing obstacles under power transmission and distribution lines. Background Art

[0002] Overhead distribution lines are a common way of setting up power lines, but there are hidden dangers of tree lines between a small number of distribution lines and trees used for urban beautification, especially the trees under the distribution lines. The pruning of these trees has become a key issue for the safe operation of urban lines. Because the trees are likely to touch the lines when they grow on their own, causing phase-to-phase short circuits, often causing large-scale power outages, and the high-voltage current they carry may injure passing workers, so trees need to be pruned in a timely manner.

[0003] With regard to the above-mentioned related technologies, the inventor believes that the general line tree obstacle clearing work is carried out under the condition of line power outage. When the traditional high-branch saw is used, the workers hold the operating lever for a long time, which is very physically demanding, and it is impossible to clear branches that are too high. It is time-consuming and laborious and fails to achieve the desired effect. Summary of the invention

The top end of the operating rod 2 is connected to the bottom end of the saw head assembly 1 through a threaded connection.

[0032] In one embodiment, the saw head assembly 1 may be a manual saw 11 , and an operator may use the manual saw 11 to prune branches. The bottom end of the manual saw 11 is relatively connected to the operating rod 2 .

[0033] Reference Figure 2 , Figure 3 In one embodiment, the saw head assembly 1 can also be an electric saw head 12, a power supply rod is arranged inside the operating rod 2, and a power supply structure 4 for supplying power to the electric saw head 12 is arranged inside the operating rod 2, and a control structure 3 for controlling the opening and closing of the electric saw head 12 is also arranged on the outside of the operating rod 2.

[0034] The control structure 3 includes a conversion control connector 31, one end of which is relatively connected to the operating rod 2, and the conversion control connector 31 includes a main body 32 close to the operating rod 2, and a clamping part 33 is provided on the side of the main body 32 close to the electric saw head 12, and the clamping part 33 is hinged to the main body 32.

[0035] One end of the main body 32 away from the clamping part 33 is connected to the operating rod 2. The clamping part 33 includes two clamping plates 331 arranged opposite to each other. The clamping plates 331 are hinged to the main body 32, and an arc groove 333 is provided on the side of the clamping plate 331 away from the operating rod 2. A clamping plate 334 is fixedly connected inside the arc groove 333. An insulating rod 121 is fixedly connected to the tail end of the electric saw head 12. An annular groove 122 is provided on the insulating rod 121 relative to the clamping plate 334. The insulating rod 121 at the tail end of the electric saw head 12 can extend between the two opposite clamping plates 331. The two opposite clamping plates 331 are relatively close to each other, so that the clamping plate 334 extends into the inside of the annular groove 122 to limit the movement of the electric saw head 12.

[0036] A female buckle 335 is fixedly connected to one of the two opposing clamping plates 331, and a sub-buckle 336 is fixedly connected to the other clamping plate 331. When the two clamping plates 331 are relatively fitted together, the female buckle 335 and the sub-buckle 336 are relatively fixed, and then the two clamping plates 331 are relatively fixed, so that the clamping plates 331 lock the electric saw head 12.

[0037] The power supply structure 4 includes a control motor 41 fixedly connected to the main body 32, and the control motor 41 is used to drive the operation of the electric saw head 12. A wireless receiver 42 is also fixedly connected to the main body 32, and the wireless receiver 42 can receive a control signal to control the opening and closing of the control motor 41. A lithium battery is fixedly connected inside the insulating rod 121, and the lithium battery can power the control motor 41.
