Description

Technical Field

[0001] The utility model relates to the technical field of electric tools, in particular to an overhead line tractor. Background Art

[0002] Wireline construction is a process with high technical requirements and difficult methods among the three major processes of power transmission lines (foundation, tower, and wireline are usually referred to as the three major processes). After years of development, my country's wireline construction has been upgraded from manual wireline to tension wireline, which has greatly improved both the construction speed and the construction quality. When wireline is erected at high altitude, a wireline tractor is required. When using it, fix the new wire to the bottom of the equipment, and then fit the bottom of the equipment's power roller to the guide wire and move on the guide wire.

[0003] However, the existing equipment does not have a power roller with a quick disassembly and assembly function. Before installing the equipment on the guide line, it is necessary to remove multiple screws that fix the power roller. After the equipment is installed on the guide line, it needs to be installed one by one again, which reduces the installation efficiency. For this reason, an aerial wire traction vehicle is proposed.

Then the installation plate is placed under the guide line, and the two vertical plates are inserted into the two installation grooves at the same time. The vertical plate drives the card block, and the card block squeezes the trapezoidal block on one side. When the inclined surface of the trapezoidal block is out of contact with the inclined surface of the card block, the spring squeezes the trapezoidal block to make it stuck on the top of the card block to realize the installation of the vertical plate, replacing the traditional mode of fixing the power roller with bolts, simplifying the operation steps, reducing the time spent on disassembly and assembly, and improving construction efficiency.
