Description

Technical Field

[0001] The invention belongs to the technical field of cable laying auxiliary equipment, and in particular relates to a traction assisting device for laying power cables. Background Art

[0002] Power cables are conductors for transmitting electric energy or signals, usually composed of several or several groups of conductors. In recent years, with the increasingly rapid pace of urban modernization, people's demand for electricity has also increased. When the cable is produced, it is coiled and wound on a cable reel. When the cable is actually used, it is difficult to move the cable reel to the laying position due to the heavy weight of the cable reel. When laying the cable, it is difficult to rotate the cable reel by manpower. Usually a traction device is required to cooperate with the laying. The traction device is used to pull the cable from the surface of the reel to assist in the laying of the cable. Existing cable traction equipment generally directly pulls the cable through a traction wheel. Since the cable itself is heavy, the traction force will mainly act on the cable body, which will form a large pulling force on the cable body, which is easy to cause damage to the cable and affect the laying process. Summary of the invention
