Automatic unhooking lifting tool

Abstract

The invention relates to an automatic unhooking lifting tool. The automatic unhooking lifting tool comprises a support. The support is longitudinally connected with pull blocks, lifting hooks and shackles are arranged on the lower sides of the pull blocks, and tying ropes are arranged between the lifting hooks and the shackles. The support comprises two longitudinal beams, and first flying shoresare arranged between the same ends of the longitudinal beams. The pull blocks comprise inner blocks and outer blocks, and the upper sides of the inner blocks and the outer blocks and the correspondinglongitudinal beams are fixed together. Connecting rods are arranged below the longitudinal beams, rotary shafts are evenly distributed on the connecting rods longitudinally, and the rotary shafts arelocated between the inner blocks and the outer blocks separately. Hooking shafts and buckling shafts are arranged between the two ends of the lower sides of the inner blocks and the outer blocks. Thelifting hooks comprise straight rod sections and U type sections connected with one ends of the straight rod sections into a whole. The outer ends of the straight rod sections are hinged to the rotary shafts, and the inner ends of the straight rod sections are hinged to the hooking shafts. The two ends of the shackles are fixed to the buckling shafts. A second flying shore is connected between the two connecting rods, and a push-and-pull mechanism for driving the connecting rods to stretch and shrink front and back is arranged on one side of the second flying shore. By the adoption of the lifting tool, the unloading efficiency can be improved, and potential safety hazards are eliminated. The automatic unhooking lifting tool is suitable for the occasions such as wharfs and harbors needingcontainer bag transferring.

Description

technical field [0001] The invention relates to a sling. Specifically, it is a spreader used to lift multiple tons of bags at the same time and can be automatically unhooked. It is suitable for occasions such as wharfs and ports that require transshipment of tons of packages. Background technique [0002] At present, most of the lifting equipment in docks, ports and other places are equipped with spreaders for transferring goods such as ton bags. The sling includes a support arranged horizontally, the support is connected with a pull block longitudinally, and the lower side of the pull block is connected with a suspension hook. Before lifting, it is necessary to manually put the rope cover on the ton bag on the hook. After hoisting the ton bag to the unloading position, it is necessary to manually remove the rope cover on the ton bag from the hook. When unloading, it is necessary to manually remove the rope cover on the ton bag from the hook, and the unloading efficiency...

AI Technical Summary

Problems solved by technology

When unloading, it is necessary to manually remove the rope cover on the ton bag from the hook, and the unloading efficiency is low

And because the rope cover on the ton bag is removed from the hook by hand, the operator needs to come under the spreader, which poses a safety hazard
