Description

Technical Field

[0001] The invention relates to the technical field of cable tensioners, in particular to a portable cable tensioner for reinforcing electric poles. Background Art

[0002] With the development of society, power-related equipment is widely used in daily life. Electricity is one of the most important energy sources in life. Transmission poles are important in the transmission of electricity. When installing poles, the wires need to be tightened and reinforced to prevent the wires from loosening. The wire tensioner can effectively help tighten the wires. Generally, the wires need to be tightened when they are pulled, so that the transmission lines can be safer.

[0003] The wire tensioner, also known as the ratchet tensioner, is used to tighten the wire during the construction of overhead line installation. The wire is tightened by pulling the special wrench. The special wrench is directly connected to the tension barrel and the wire tensioner is suspended in the corresponding position and needs to be stabilized, which makes it very laborious to pull the special wrench. In addition, the tightening part of the wire contacts the ground during the tightening process, and the surface is covered with mud, which is not easy to clean. Therefore, we propose a portable wire tensioner for electric pole reinforcement. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a portable wire tensioner for reinforcing electric poles. The transmission ratio is increased by a worm gear to make wire tensioning more labor-saving.
