The invention belongs to the technical field of marine equipment, and relates to an automatic steel wire rope tensioning mechanism, a suspension arm and a marine fender retracting and releasing device.The automatic steel wire rope tensioning mechanism comprises a fixed pulley block and a movable pulley block, and the fixed pulley block comprises a plurality of fixed pulleys arranged side by side and a fixed pulley supporting frame; the movable pulley block is located below the fixed pulley block and comprises a plurality of movable pulleys, a movable pulley supporting frame, a balance weight and a plurality of limiting wheels, the movable pulleys are installed on the upper portion of the movable pulley supporting frame side by side, the balance weight is installed on the lower portion of the movable pulley supporting frame, and the limiting wheels are installed on the side wall of the movable pulley supporting frame. The automatic steel wire rope tensioning mechanism adopts a pulley block form, automatically tensions the steel wire rope under the action of gravity, and is convenient to use; a movable pulley block adopts a self-aligning bearing, so that a movable pulley is automatically adjusted to the direction of a steel wire rope, the torsional moment is eliminated, a counterweight is prevented from being blocked in a slideway, and an automatic tensioning mechanism is mounted in a suspension arm of the marine fender retracting and releasing device, so that potential safety hazards are eliminated.

    本发明属于船用设备技术领域,涉及一种钢丝绳自动涨紧机构、吊臂及船用护舷收放装置,所述钢丝绳自动涨紧机构包括定滑轮组及动滑轮组,定滑轮组包括多个并排设置的定滑轮及定滑轮支撑架;动滑轮组位于所述定滑轮组的下方,包括多个动滑轮、动滑轮支撑架、配重及多个限位轮,动滑轮支撑架的上部并排安装多个动滑轮,下部安装配重,在动滑轮支撑架的侧壁安装多个限位轮。本发明钢丝绳自动涨紧机构采用滑轮组形式,可靠重力自动张紧钢丝绳,使用方便;动滑轮组采用调心轴承,使动滑轮自动调整到钢丝绳方向,消除扭转力矩,避免配重在滑道内卡堵,自动涨紧机构安装安装在船用护舷收放装置的吊臂内部,消除安全隐患。
