Description

Technical Field

[0001] The utility model relates to the field of power transmission line erection, in particular to a power transmission line cross-line erection mechanism for a multi-rotor unmanned aerial vehicle. Background Art

[0002] At present, the process of laying transmission lines across the line is often restricted by terrain and environmental characteristics. For example, the line laying process must cross some rivers, lakes, hills, canyons, forestry nursery areas, etc. These factors cause the construction cost to increase exponentially, the construction progress has to be delayed or even interrupted, and the construction quality cannot be guaranteed. Therefore, during the laying of transmission lines, drones are used to drive the transmission lines to move, so as to lay the transmission lines.

[0003] Prior art, such as CN212695612U, discloses a transmission line cross-line laying device based on a multi-rotor drone, which includes a body and a traction rope. The body is provided with a traction rope unwinding mechanism, a drum delivery mechanism and a traction rope delivery mechanism, which can reduce the obstruction of objects such as tree branches to the transmission line during the laying process, making it convenient for workers to pull the transmission line.

[0004] However, the prior art cannot effectively limit the guide during the traction process of the transmission line. During the traction process, the single set of transmission wheels used can easily cause the transmission line to slip on the transmission wheels, making it inconvenient to pull out the transmission line. In addition, the prior art structure is too complicated and heavy when used, which affects the use of the drone. Utility Model Content

When the clamping belt 2 deforms and squeezes the power transmission line, the arc surface reduces the wear of the clamping belt 2. A motor 6 is installed on the outer wall of the fixed frame 1. The output end of the motor 6 is connected to the transport roller 3 for transmission, driving the transport roller 3 to rotate, thereby driving the power transmission line to move, which is convenient for transporting the power transmission line. A groove is provided on the inner wall of the transport roller 3. A power transmission frame 102 is connected to the side of the fixed frame 1. The power transmission frame 102 is electrically connected to the multi-wing UAV through a wire, and the power transmission frame 102 is connected to the motor 6 and the electric cylinder 7 through a wire.

[0032] See also Figure 3 and Figure 5 A cleaning roller 4 is connected to the interior of the fixed frame 1 below the transport roller 3, a protruding wheel 401 is installed on the outer side of the cleaning roller 4, and the protruding wheel 401 fits with the slot inside the transport roller 3, one end of the transport roller 3 and the cleaning roller 4 both extend to the outside of the fixed frame 1, and the ends of the transport roller 3 and the cleaning roller 4 located on the outside of the fixed frame 1 are connected with a linkage tooth 5, and the transport roller 3 and the cleaning roller 4 are connected by the linkage tooth 5, which can facilitate the cleaning of the slot in the transport roller 3 and reduce the wear of impurities on the transmission line.
