Description

Technical Field

[0001] The utility model relates to the technical field of cable traction, and more specifically, to a traction device for electric wires and cables. Background Art

[0002] A tractor for pulling wires and cables in pipelines is specially designed to provide the necessary pulling force and guidance when laying wires and cables inside pipelines or pipes. This tractor effectively prevents damage or breakage during the laying process by ensuring that the cable can overcome the friction and bending in the pipeline.

[0003] In the existing technology, firstly, some devices are more susceptible to vibration and impact when moving in the pipeline, which may lead to unstable traction operation, increase equipment loss and operational risks. During the cable traction process, vibration may cause inaccurate cable position and affect the installation quality, especially in cases where precise wiring is required. Secondly, the loading and unloading of detectors in some devices becomes time-consuming and complicated, increasing operation time and cost. When the detectors need to be quickly replaced to adapt to different detection tasks, the lack of quick snap-on function will limit the adaptability and versatility of the equipment, and the maintenance and inspection of the device will become more complicated. Finally, operators of some devices may need to manually perform complex adjustments and locks, which not only increases the difficulty of operation, but also may lead to reduced efficiency and increased errors. In emergency situations, such as the need to quickly release the detectors to deal with sudden problems, the operational risks and the possibility of equipment damage may be increased.
