Steel wire rope tensioning device

Abstract

The invention relates to a steel wire rope tensioning device, comprising a pulley (1), a steel wire rope clip (2), a locknut (3), an adjusting nut (4), a tensioning cylinder (5) and a tension bracket (6), wherein the pulley (1) is connected with the tension bracket (6); the tensioning cylinder (5) extends horizontally along the U-shaped groove formed on the upper part of the tension bracket (6); the adjusting nut (4) and the locknut (3) are arranged on the part, which extends out of the tension bracket (6), of the tensioning cylinder (5), and the steel wire rope clip (2) is arranged at the tail end of the tensioning cylinder (5); a steel wire rope is penetrated into the tensioning cylinder (5) by bypassing the pulley (1), and the tail end of the steel wire rope is tightly clamped by the steel wire rope clip (2); and the lower part of the tension bracket (6) is connected with an upper roller shutter shaft. By adjusting the locknut (3) and the adjusting nut (4), the degree of tightness of the steel wire rope can be adjusted; in addition, by adjusting relative position of the tensioning cylinder (5) and the upper roller shutter shaft, the upper roller shutter shaft is kept in a straight state and is leveled with a lower roller shutter shaft, in this way, failures in use of a roller shutter are reduced, and labor power as well as time needed for operation of the roller shutter aresaved.

Description

technical field [0001] The invention relates to a supporting equipment for pens and houses, in particular to a steel wire rope tensioner. Background technique [0002] In the modern large-scale dairy farming industry, it is necessary to build a large number of dairy farms, and no matter how big or small the dairy farm is, all kinds of productive buildings such as cowsheds and milking parlors are indispensable. Because most of the cattle farms are built in the open field, when the windy season comes, the cattle house needs to be able to resist the wind and sand, and in winter it needs to be protected from the cold and warm, and it needs to be ventilated all year round, especially in summer. To accomplish all this, the best way is to make windows (except passages) on the entire side walls of these buildings, and then install roller blinds. [0003] Since the construction errors of buildings such as cowsheds are much greater than the manufacturing errors of mechanical and elec...

Problems solved by technology

[0004] In the previous design, the upper roller shade shaft of the roller blind is directly connected with the suspension wire rope, so that the upper roller shade shaft is not easy to be leveled during installation, and its axial position cannot be adjusted, so that the upper roller shade shaft and the lower roller The axial position of the roller blind shaft is not easy to align, which will cause the roller blind to wrinkle, partially bulge when winding, and the winding is laborious, which will eventually make the roller blind unusable
