The invention discloses a pulley mechanism for an offshore platform crane, and particularly relates to the technical field of crane pulley mechanisms, the pulley mechanism comprises a base for supporting, the bottom of the base is provided with a positioning retractable assembly, the positioning retractable assembly comprises a protection box arranged at the top of the base, and a worm gear is arranged in the protection box; a worm is arranged on the outer side of the worm gear. Through corresponding cooperative use of all the structures, a cable is positioned through the positioning arc groove during winding and unwinding, the stability of the cable during winding and unwinding is ensured, the position of the arc supporting piece can be properly adjusted, and it is ensured that the arc supporting piece can stably support the cable during winding and unwinding; and the situation that when materials are hoisted, torsion is generated during cable winding and unwinding, the materials shake is avoided, a clamping column can be clamped on a ratchet wheel, the function of positioning the ratchet wheel is achieved, the cable is positioned during cable winding and unwinding, and the cable winding and unwinding accuracy is achieved.
本发明公开了用于海上平台起重机的滑轮机构,具体涉及起重机滑轮机构技术领域,包括用于支撑的底座,所述底座的底部设置有定位收放组件,所述定位收放组件包括设置在底座顶部的防护箱,所述防护箱内设置有蜗轮,所述蜗轮的外侧设置有蜗杆。本发明通过各个结构的相应配合使用,通过定位弧槽对缆绳收放时进行定位,确保缆绳收放时的稳定性,弧托件能够进行适当的位置调节,确保弧托件能够稳定的对缆绳收放时进行支撑,避免物料在进行吊运时由于缆绳收放时产生扭力而造成物料发生晃动,卡柱能够卡在棘轮上,实现对棘轮进行定位的功能,实现缆绳在进行收放时对其进行定位,实现缆绳收放时的精准度。
