Herringbone overturn lifting appliance for cylinder body bobbin core set

Abstract

The invention relates to an overturn lifting appliance, specifically relates to a herringbone overturn lifting appliance for hoisting cylinder body bobbin core set, and belongs to the technical field of lifting appliance. The herringbone overturn lifting appliance comprises a left lifting arm and a right lifting arm, the upper end of the right lifting arm and the upper end of the left lifting arm are in a rotation connection through a lifting assembly so as to form an integrated herringbone structure; one side, which faces the right lifting arm, of the left lifting arm is provided with a lifting arm slide track; one side, which faces the left lifting arm, of the right lifting arm is provided with a lifting arm slide block, which matches with the lifting arm slide track; the lifting arm slide block is arranged in the lifting arm slide track; the lower end of the left lifting arm is provided with a left-rotating assembly, the left-rotating assembly faces the right lifting arm side and is connected to a left clamping plate assembly; the lower end of the right lifting arm is provided with a right-rotating assembly, the right-rotating assembly faces the left lifting arm side and is connected to a right clamping plate assembly. The herringbone overturn lifting appliance has a simple, compact, and reasonable structure, can overturn agilely and reliably, can make work safe and stable, is laborsaving in operation, and avoids the falling off of the bobbin core set during the hoisting process.

Description

technical field [0001] The invention relates to an overturning sling, in particular to a herringbone overturning sling for hoisting cylinder bobbin core groups, and belongs to the technical field of slings. Background technique [0002] In the core assembly, dip coating, drying, storage and lower core line of the production cylinder, it is not only necessary to transfer the assembled package core group, but also to change the state of the package core group from the flat core assembly state to another A vertical storage state. On the entire cylinder line, it is necessary to use the turning spreader twice. The first time is to lift the fastened bobbin core set on the core pre-installation seat, rotate it 90° and place it on the dip-coating pre-assembly seat. The second time is to lift and rotate the bobbin core group in the three-dimensional warehouse pallet by 90° and place it on the pre-installation seat of the static pressure line [0003] The original overturning sprea...

Problems solved by technology

[0004] When the original spreader is used, the lock on the right arm is often not tight. After analysis, it is found that the locking mechanism of the right arm is inconvenient to operate. Workers sometimes need to hit the handle with a hammer to hit the handle to the lock. Tight position, sometimes loosen after locking

The operator is very laborious when opening the right boom of the spreader and retracting the right boom of the spreader
