Abstract

The invention relates to a simple tensioner of lossless steel cables. The simple tensioner is characterized by comprising a U-shaped fixing bracket, wherein two top ends of the U-shaped fixing bracket are hinged with fixing pulleys respectively; the bottom of the U-shaped fixing bracket is connected with a regulating stem which can go up and down relative to the U-shaped fixing bracket; the upper end of the regulating stem is connected with a detachable regulating pulley; and the regulating pulley and the fixing pulley are arranged at a same longitudinal plane. The regulating stem is in threaded connection with a stair-step shaped regulating nut, and the excircle of the stair-step shaped regulating nut is connected with a through hole at the bottom of the U-shaped fixing bracket smoothly. The simple tensioner disclosed by the invention has simple principles, low manufacturing cost and great popularization value both in power transmission line works and various cableways such as forestry cableways, freight transport cableways, passenger transport cableways, overhead power transmission lines and the like.

Description

technical field [0001] The invention relates to a simple tensioner for non-destructive steel wire ropes, which is used for non-destructive tensioning of steel wire ropes and also suitable for non-destructive tensioning of other flexible cables. Background technique [0002] At present, commonly used wire rope tensioners, also known as flange bolts or turnbuckles such as figure 1 As shown, the tightness of the wire rope can only be adjusted by connecting the wire rope at both ends, and the adjustment range is very limited. It is only suitable for the adjustment of fixed steel wire ropes, such as tensioned stay ropes, etc., and it needs to be embedded in the steel wire ropes during installation. Tensioning the steel wire rope at any position cannot satisfy the tension of the closed loop steel wire rope (flexible rope). Tensioning the closed loop wire rope is troublesome without being able to adjust the position of the support of the closed loop wire rope or the position of t...
