The invention discloses a hook-headed pulley capable of preventing double ropes from twisting, which comprises a ship main body and a main crane, the main crane is arranged on the ship main body, a suspension arm of the main crane is connected with the hook-headed pulley through double lifting ropes, the hook-headed pulley is arranged on a crane pulley box, and the crane pulley box is used for limiting the double lifting ropes. The hook head pulley is provided with a pin roller so that the double lifting ropes can abut against the pin roller in a sliding mode, the crane pulley box is connected with a crane lifting hook, the crane lifting hook is connected with a lifting rigging, and the lifting rigging is connected with an installation structure so that the installation structure can be lifted and placed. The hook-headed pulley capable of preventing the double ropes from twisting, provided by the invention, is suitable for an ocean engineering ship crane to carry out installation work of a deepwater large-scale structure in a double-rope hoisting mode, the offshore construction capability of existing ship resources is enhanced, and the competitiveness of the hook-headed pulley in the field of installation of the deepwater large-scale structure is improved; and the structure is simple, the prefabrication cost is low, and the construction efficiency is high.

    本发明公开了一种防止双绳打扭的钩头滑轮,该防止双绳打扭的钩头滑轮包括船舶主体和主吊机,主吊机设置在船舶主体上,主吊机的吊臂通过双吊绳与钩头滑轮连接,钩头滑轮设置在吊机滑轮箱上,吊机滑轮箱以对双吊绳限位,钩头滑轮上设有滚柱,以使双吊绳滑动抵接在滚柱上,吊机滑轮箱上连接有吊机吊钩,吊机吊钩上连接有吊装索具,吊装索具与安装结构物连接,以对安装结构物吊放。本发明提供的防止双绳打扭的钩头滑轮适用于海洋工程船舶吊机在双绳吊装模式下进行深水大型结构物的安装工作,增强现有船舶资源海上施工能力,提升在深水大型结构物安装领域的竞争力,并具有结构简单、预制成本低、施工效率高等优点。
