Description

Technical Field

[0001] The utility model belongs to the technical field of traction machines, in particular to an adjustable electric wire traction machine. Background Art

[0002] Wires refer to conductors that transmit electrical energy. They are divided into bare wires, electromagnetic wires, and insulated wires. Bare wires have no insulation layer, including copper and aluminum flat wires, overhead stranded wires, and various profiles (such as profiled wires, busbars, copper bars, aluminum bars, etc.). Its conductor is mainly copper wire, which should have a thin insulation layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, and solvent resistance. When the wires are in use, they need to be wired according to the buried position. Therefore, a wiring traction machine is needed to wire and pull the wires so that the wires can move in the pipeline to meet the use requirements.

[0003] However, when the traction drum in the traction machine reels the cable, the wires tend to pile up together, which affects the efficiency of the traction drum in reeling in the wires and reduces the practicality of the entire device. It is also difficult to pull wires of different models, so the practicality is low. Utility Model Content
