[0001] The present application relates to the technical field of conductor straightening, and in particular to an overhead conductor straightening device. Background Art
[0002] As an essential component of the power system, overhead conductors are responsible for efficiently and stably transmitting electricity from power stations to various power-consuming areas. With the continuous growth of electricity demand and the expansion of the power grid, the performance and quality requirements of overhead conductors are also increasing. Overhead conductors typically need to span long distances and must withstand a variety of complex environmental factors such as strong winds, ice and snow, and temperature fluctuations. These factors can cause the conductors to bend and deform to varying degrees, thereby affecting their electrical performance and mechanical strength.
[0003] In the related art, since some overhead conductor straightening devices on the market lack a precise guiding and positioning mechanism, operators need to spend a lot of time adjusting the conductor position to align with the entrance of the straightening device. Especially when dealing with conductors with large initial bends, the difficulty of adapting the bent part to the device entrance increases sharply, making the alignment operation more cumbersome. This not only reduces work efficiency, but also easily leads to operational errors due to repeated adjustments, so it needs to be improved. Utility Model Content
