Problems solved by technology

[0002] When the power system is wired at a long distance, the cables on the pay-off car climb up to the wire pole (or line tower) after passing through the guide wheels on the tension car bracket. The climbing angle behind the wheel is often very large, and because the cable is heavy, the cable often jumps a lot during the stringing, which seriously affects the stringing progress
With the development of science and technology, the cable used in power system wiring now has an optical fiber used to measure the temperature of the cable when the cable is in use. Since the optical fiber is not suitable for bending, if the cable climbs after passing the tension car The angle is large and the swing range is large, the optical fiber is easy to break, which affects the use of the cable

Abstract

The invention relates to a tension trolley supporting and locating guide pulley capable of ascending and descending. The tension trolley supporting and locating guide wheel capable of ascending and descending comprises a guide pulley support. A guide pulley body set is arranged on the guide pulley support, four landing legs are connected to the bottom of the guide pulley support, and each landing leg is correspondingly provided with a plurality of screw holes. Ascending and descending of the guide pulley are realized by adjusting the height of the landing legs on a tension trolley support, the guide pulley body set can support and locate cables, and therefore the effect that the cables are smoothly erected is guaranteed.

Description

technical field [0001] The invention relates to a guide wheel, in particular to an up-and-down supporting and directional guide wheel for a tension car used for electric power wiring. Background technique [0002] When the power system is wired at a long distance, the cables on the pay-off car climb up to the wire pole (or line tower) after passing through the guide wheels on the tension car bracket. The climbing angle behind the wheel is often very large, and because the cable is heavy, the cable often jumps and swings a lot during stringing, which seriously affects the stringing progress. With the development of science and technology, the cable used in power system wiring now has an optical fiber used to measure the temperature of the cable when the cable is in use. Since the optical fiber is not suitable for bending, if the cable climbs after passing the tension car If the angle is large and the swing range is large, the optical fiber is easy to break, which affects the...
