Description

Technical Field

[0001] The invention relates to the technical field of power transmission and operation inspection, and in particular to a high-position branch pruning tool. Background Art

[0002] Transmission operation and inspection is the work of operating, maintaining, repairing and troubleshooting transmission lines and equipment. It is mainly responsible for daily inspection, status detection, defect management, hidden danger investigation and channel protection of transmission lines. The purpose of line inspection is mainly to protect the safety of high-voltage lines and to find out the construction conditions near the lines.

[0003] In daily work, the impact of high-level tree branches on overhead cables is the focus of investigation. Growing branches may get entangled in cables, especially in windy or rainy days. The shaking of branches will exert a pulling force on the cables, which may cause the cables to break or be damaged. When branches come into contact with high-voltage lines, a conductive path may be formed, leading to a short circuit fault. A short circuit will cause the current to increase instantly, which may burn out wires, damage power equipment, and even cause power outages. In addition, the branches and leaves of trees are too close to transmission lines, which can easily cause electric sparks or short circuits, causing the lines to trip. In severe weather, broken branches of trees may crush wires or poles, causing power outages. In addition, trees that are too close to wires may also cause safety accidents such as fires, especially in dry and windy seasons. The friction between branches and wires may produce sparks and cause fires.

[0004] For the above reasons, it is necessary to regularly prune branches during power transmission and inspection work to prevent them from growing to the height of the cables and reduce the risk of entanglement and pulling. At present, the pruning of high branches usually requires the use of aerial work vehicles, but some sections of the road are narrow, and some roads are even rugged and difficult to reach, so vehicles cannot reach and trees cannot be pruned. In this case, if a high-position branch pruning tool with a lightweight structure and handheld operation can be designed, it is expected to improve the pruning efficiency of high-position branches in rugged areas and overcome the problem that large machines and vehicles cannot reach. Summary of the invention

In this way, by adjusting the position of the fixed block in the installation groove, the tightness of the wire rope can be adjusted more conveniently. Two support rods can be set, so that combined with the rotating frame, a three-point support structure is formed for the ring body to ensure that it has good stability. Ear seats can be set on the left and right sides of the ring body, and after being fitted with the sheet-shaped support rods, they are fixed by bolts and nuts, which is convenient for installation. A limit plate can be set at the upper end of the slit to limit the upward distance of the tool holder. The main holding ring and the auxiliary holding ring are respectively held on the outside of the main arm and the auxiliary arm, and the two are connected into one by a connecting plate, and then bolts and nuts are installed through the wing plates on both sides, so that the main arm and the auxiliary arm are fixed. The auxiliary arm and the auxiliary holding ring can adopt a sliding matching structure, which is convenient for pushing and pulling the auxiliary arm within a short distance, thereby facilitating the adjustment of the angle of the ring body. The collection bag on the ring body can be a nylon mesh bag, which is not easy to be damaged. The main arm, the first fixed handle, the movable handle, the sliding sleeve, the auxiliary arm, and the second fixed handle should be made of insulating materials to ensure safety. The wire rope fits the inner wall of the sliding sleeve to maintain a sliding fit structure to ensure that the wire rope has a relatively smooth travel when being pulled and reset.

[0019] The present invention provides a high-position branch pruning tool. The tool can be operated by one person, so it is suitable for rugged and narrow working environments. Moreover, the tool adopts a vertical shearing structure and is provided with a spring reset mechanism, which ensures a high shearing efficiency.
