AI Technical Summary

Technical Problem

In the existing technology, flexible cables are prone to sag due to gravity when the actuator moves horizontally and reciprocating, resulting in uncontrollable shape and position. Moreover, existing storage solutions cannot meet the requirements of compact design, especially for the immature reliable storage solutions for oil, electricity and gas hybrid cables.

Method used

A horizontal cable winding pre-tensioning follow-up double-stroke mechanism is adopted. Through the combination of the moving pulley cable winding mechanism and the wire rope drum, combined with the ball linear guide pair and the detachable half clamp positioning, the pre-tensioning follow-up and double-stroke winding of the cable are realized, ensuring that the cable remains taut at all times during the movement.

Benefits of technology

It achieves flexible layout and efficient storage in a limited space, avoids interference between pipelines and other structural components, is suitable for compact layout of oil, electricity and gas mixed pipelines, and has a simple structure and is easy to debug.

Abstract

For complex electromechanical-hydraulic integrated equipment, the actuators, which are distributed in a manner, are often connected to the power source via cables, oil pipes, and air pipes. While cable chains can be used for guidance and storage, their linear density is much greater than that of the cables. To ensure sufficient suspension length, they often have large cross-sectional dimensions, especially when the number of cables is small. This results in cable chains occupying significant additional installation and movement space, failing to meet the requirements of compact design. This invention proposes a horizontal cable reel pre-tensioning follow-up mechanism. The horizontal cable retracts around a movable pulley, and the slider containing the pulley is pre-tensioned and limited by a wire rope drum mechanism along a horizontal guide rail. This allows for flexible arrangement within a limited installation space, enabling pre-tensioning, follow-up, and double-stroke retraction of horizontally arranged oil, electrical, and air cables that perform large-stroke linear reciprocating motions.
