Circular large article clamping hoisting sling

Abstract

The invention discloses a circular large article clamping hoisting sling. The circular large article clamping hoisting sling comprises a fixed disk frame. The outer side of the fixed disk frame is provided with bolt holes in a through mode. The fixed disk frame is movably connected with bolt shafts through the bolt holes. The top of the fixed disk frame is fixedly connected with tension springs. One end of each tension spring is fixedly provided with a tension spring hook. Mounting grooves are formed on the outer side of the top of the fixed disk frame in an embedded mode. The fixed disk frameis movably connected with clamping arms through the mounting grooves. One side of the top of each clamping arm is provided with a mounting hole in a through mode. The clamping arms are movably connected with sling ropes through the mounting holes correspondingly. One end of each sling rope is fixedly connected with a fixing button. The circular large article clamping hoisting sling is provided with the fixed disk frame, the clamping arms and a triangular support. When the circular large article clamping hoisting sling conducts hoisting on a circular article, working staff do not need bundle the article through a rope and can enable the circular article to be hoisted with less time and labor. Moreover, the rope cannot get loose and the bundling position does not need to be adjusted repeatedly. The circular large article clamping hoisting sling facilitates using by the working staff through the tension springs and the tension spring hooks.

Description

technical field [0001] The invention relates to the technical field of slings, in particular to a sling for clamping large circular objects. Background technique [0002] The single hook is easy to manufacture and easy to use, but the force is not good, and it is mostly used in workplaces with a lifting capacity of less than 80 tons; when the lifting capacity is large, a double hook with symmetrical force is often used. The laminated hook is riveted by several cut and formed steel plates. When individual plates crack, the whole hook will not be damaged, and the safety is better, but the weight is relatively large. Most of them are used for lifting large lifting capacity or lifting molten steel drums. on the crane. The hook is often impacted during operation and must be made of high-quality carbon steel with good toughness. [0003] However, the existing slings for large round objects are not convenient for the staff to use when picking up the round objects. It is also nece...
