Problems solved by technology

[0002] At present, in the power transmission and transformation facilities in the power industry, there are often tree branches that affect the safety of the wires. To eliminate the influence of tree branches, it is necessary to negotiate with the garden department or residents, and sometimes even need to carry out Compensation will cause a lot of trouble. If only the branches are removed, the current tools are difficult to adapt to. Most of them are completed by manual ladders, which wastes manpower and material resources, and the speed is slow.

Embodiment Construction

[0011] Examples, see attached Figure 1~3 , the suspended movable pruning device is a trapezoidal outer shield 15, and a motor 13 is installed at the bottom. Drive sprocket 11 is housed on the shaft that goes out of machine 12. The top of the outer shield 15 is provided with a square hole 15-1, and two parallel insulating supports 10 are fixed above the square hole 15-1 of the outer shield 15, and a bearing seat 21 is arranged on the upper inner side wall of the support 10. The built-in driven sprocket shaft 7 of the bearing in the bearing seat 21, the driven sprocket 8 is installed on the driven sprocket shaft 7 in the support 10, and the driven sprocket 8 is connected with the drive sprocket 11 transmission with the chain 9. On the driven sprocket shaft 7 outside the bracket 10, a lower roller 6 with a concave arc shape is installed, and two return springs 5 ​​are fixedly installed on the driven wheel shaft 7 outside the lower roller 6, and the other ends of the two return ...

Abstract

The invention belongs to power industry power transmission and transformation safety guaranteeing construction equipment and particularly relates to a suspension type movable branch cutting device. A motor (13) is mounted on the lower portion inside a trapezoid outer shield (15). The upper end extension shaft of the motor (13) is connected with a worm wheel and worm type reducer (12). A drive sprocket (11) is mounted on the extension shaft of the reducer (12). A support (10) is fixed on the upper portion outside the outer shield (15). A driven sprocket (8) is mounted on a driven sprocket shaft (7) in the support (10). The driven sprocket (8) is in transmission connection with the drive sprocket (11). Two reset springs (5) are fixedly mounted on the driven sprocket shaft (7) on the outer side of a lower roller (6). The reset springs (5) are respectively movably connected to two upper roller shafts (2). A first chain saw sprocket (20) and a second chain saw sprocket (18) are mounted on the lower end extension shaft of the motor (13). A chain saw (16) is mounted on each of the first chain saw sprocket (20) and the second chain saw sprocket (18). The suspension type movable branch cutting device automatically controls the motor to move so as to cut the branches, causing potential safety hazard, below electric wires, and safe circuit power supply can be guaranteed.

Description

technical field [0001] The invention belongs to construction equipment for power transmission and transformation safety assurance in the electric power industry, in particular to a suspended movable pruning device. Background technique [0002] At present, in the power transmission and transformation facilities in the power industry, there are often tree branches that affect the safety of the wires. To eliminate the influence of tree branches, it is necessary to negotiate with the garden department or residents, and sometimes even need to carry out Compensation will cause a lot of trouble. If only the branches are removed, the current tools are difficult to adapt to. Most of them are completed by manual ladders, which wastes manpower and material resources, and the speed is slow. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a suspension type movable pruning device which can...
