The invention discloses an adjustable hanging bracket for mounting a marine propeller shaft nut. The adjustable hanging bracket comprises a bracket body, a roller assembly, a rear supporting guide wheel assembly and a front supporting guide wheel assembly, the roller assembly and the rear supporting guide wheel assembly are arranged on one side of the frame body, a roller of the roller assembly is arranged in a threaded hole of the propeller shaft nut, and a first guide wheel of the rear supporting guide wheel assembly abuts against the rear end face of the propeller shaft nut. The front supporting guide wheel assembly is arranged on the other side of the frame body, and a position-adjustable second guide wheel of the front supporting guide wheel assembly abuts against the front end face of the propeller shaft nut. The adjustable hanging bracket effectively solves the problem that the propeller shaft nut cannot be installed on a dock and a slipway at the same time through a traditional hoisting tool, the use generalization of the propeller shaft nut hoisting tool is achieved, the adjustable hanging bracket is simple in structure, easy and convenient to operate and low in manufacturing cost, the propeller shaft nut can be rapidly installed in place, and the hoisting efficiency is improved. And the installation precision and the installation quality of the propeller shaft nut can be ensured.

    本发明公开了一种船用螺旋桨轴螺母安装用的可调节吊架,包括架体、滚轮组件、后支撑导轮组件和前支撑导轮组件;滚轮组件和后支撑导轮组件设置于架体的一侧且滚轮组件的滚轮置于螺旋桨轴螺母的螺纹孔、后支撑导轮组件的第一导轮抵在螺旋桨轴螺母的后端面上;前支撑导轮组件设置于架体的另一侧且其位置可调的第二导轮抵在螺旋桨轴螺母的前端面上。本发明有效解决了传统吊装工装不能同时在船坞和船台安装螺旋桨轴螺母的问题,实现了螺旋桨轴螺母吊装工装的使用通用化,且本发明的可调节吊架结构简单、操作简便、制作成本低廉,不仅能够快速将螺旋桨轴螺母安装到位,而且也能保证螺旋桨轴螺母的安装精度和安装质量。
