The invention provides a lifting hook capable of adjusting the length of a rigging, relates to the field of lifting, and is used for solving the problem of adjusting the length of the rigging of a small crane without a hoisting mechanism in the market. The device comprises a lifting hook, a supporting frame, a winding drum, a winding drum shaft and a handle. A rigging limiting hole is formed in the upper portion of the supporting frame, the rigging penetrates through the limiting hole to be wound on the winding drum, the cotter pin is pulled out, the handle is pulled out, after a first claw disc on the handle is separated from a second claw disc on the supporting frame, the handle is rotated to adjust the length of the rigging, then the handle is pushed back to enable the first claw disc and the second claw disc to be meshed with each other, and hoisting can be achieved by locking the winding drum. The device is simple in structure, can adjust the rigging to a proper length, is convenient to operate, and can meet the application in different hoisting environments.
本发明提出一种可调节索具长度的吊钩,涉及吊装领域,用于解决市面上不具备卷扬机构的小型吊机其索具长度调节问题。本发明包括吊钩、支撑架、卷筒、卷筒轴以及手柄。其中支撑架上方有索具限位孔,索具穿过限位孔缠绕在卷筒上,拔出开口销,向外拉出手柄,当手柄上第一爪盘与支撑架上第二爪盘分离后,转动手柄实现对索具长度的调节,然后推回手柄使第一爪盘与第二爪盘相互咬合,锁定卷筒即可吊装。本发明结构简单,能调节索具到合适长度,便于操作,能够满足不同吊装环境下的应用。
