Automatic adjustment type steel wire rope tensioning device

Abstract

The invention discloses an automatic adjustment type steel wire rope tensioning device. The automatic adjustment type steel wire rope tensioning device comprises a base, guide wheels, tensioning wheels, a rotating shaft, a fixed shaft, a swing arm, a fixing piece and torsional springs, wherein the guide wheels are fixed on the base; the tensioning wheels are matched with the guide wheels; the rotating shaft is connected onto the base in a rotating mode, and driving gears are fixed on the rotating shaft; the fixed shaft is fixed on the base, and driven gears engaged with the driving gears are connected onto the fixed shaft in a rotating mode; the swing arm is connected onto the fixed shaft in a rotating mode, one end of the swing arm is coupled with the tensioning wheel; the fixing piece is used for realizing relative fixation of the rotating shaft and the base; the torsional springs are also arranged on the fixed shaft in a sleeving mode, one end of each of the torsional spring is fixed with the swing arm, and the other ends of the torsional springs are fixed with the driven gears. The automatic adjustment type steel wire rope tensioning device is compact in structure, high in pretensioning efficiency, adjustable in pretensioning force, good in pretensioning effect and low in manufacturing cost, meanwhile can realize automatic pretensioning, and can be applied to small and light instruments.

Description

technical field [0001] The invention relates to a tensioning device, in particular to an automatically adjustable double swing arm steel wire rope tensioning device. Background technique [0002] With the continuous progress and development of technology, wire rope transmission has been involved in more and more fields, and continues to demonstrate its superiority, including cranes, hoists, cable cars and other large machinery fields, obstacle avoidance robots using wire rope transmission, rehabilitation exoskeleton fields, etc. . The most important issue in wire rope transmission is the pretension of the wire rope. [0003] Existing steel wire ropes in large-scale machinery such as cranes and cable cars generally adopt hydraulic cylinders to provide tension and pre-tighten them. The overall structure of this type of pretensioning device is complex and bulky, and it is not suitable for applications such as obstacle avoidance robots and rehabilitation exoskeletons where the...
