The steel wire rope body 2 is wound around the first pulley 8, the second pulley 14 and the third pulley 23. By setting the stretching structure 3, the tension of the steel wire rope body 2 can be adjusted without affecting the pulling force of the winch. The steel wire rope body 2 passes through the tensioning device body 1 and is wound around the first pulley 8, the second pulley 14 and the third pulley 23. When the steel wire rope body 2 is loose, the electric telescopic rod 6 is started to pull the connecting block 7 to move the first pulley 8. The first pulley 8 can perform secondary tensioning on the steel wire rope body 2 with the cooperation of the second pulley 14 and the third pulley 23 to prevent affecting the pulling force of the winch.
[0025] A plurality of supporting square plates 10 are installed on one side of the tensioning device body 1, on which a first bolt 11 is movably installed, and a clamping plate 12 is movably installed at one end of the first bolt 11. By setting the supporting square plates 10, the first bolts 11 and the clamping plate 12, the plurality of first bolts 11 are screwed to drive the clamping plate 12 to fit the wire rope body 2. During the transportation of the wire rope body 2, waste oil residue on the surface of the wire rope body 2 can be scraped off to prevent the oil residue from clogging the tensioning device body 1.
