Description
Technical field
The present invention relates to metallurgical industry field of steel production, the clipping card device for hoisting of specifically a kind of heavy-duty steel plate blank material and
Its application method.
Background technique
In steel casting production process, a large amount of heavy-duty steel plate blank material (long 10m, wide 1.5m, thick 0.18m, monolithic weight 14t
More than), since size is big, weight weight, require to lift by crane or transport using special large-scale suspender or fixture.To ensure transporting
During defeated, steel plate blank will not fall off from suspender or fixture, and steel mill generally uses double limb fixtures.The fixture is special steel
Material is made, altogether the limb foot fixed there are four rectangular distribution, relative position, and each limb underfooting portion is crotch-shaped.Transport steel
When plate blank material, first four limb foot crotches of double limb fixtures are stuck in below horizontal positioned steel plate blank, and four limb foot crotches
Planar central position be overlapped with steel plate blank position of centre of gravity.Four limb feet of double limb fixtures are fastened to plate slab feed collet again
It is fixed, the lifting and transhipment work of heavy-duty steel plate blank material can be carried out.To be smoothly stuck in below steel plate blank convenient for limb foot crotch,
Steel plate blank generallys use the horizontal hierarchical rule up and down of " well " font and stacks.
Double limb fixtures efficiency and safety in handling " well " font heavy-duty steel plate blank material that hierarchical rule is stacked horizontal up and down
Property is relatively high.However in steel mill, often there is the horizontal heavy-duty steel that hierarchical rule is stacked up and down of non-" well " font of handling
The case where plate blank material.In this case, using double limb fixtures, handling efficiency is lower, and steel plate blank easily occurs and falls off danger
Feelings.This is mainly caused by following reason:
1) double limb fixtures are bulky, without foot above the steel plate blank that the horizontal hierarchical rule up and down of non-" well " font is stacked
Fixture is allowed to go deep into for enough spaces or limb foot crotch can not protrude on the downside of steel plate blank.
2) steel plate blank biggish for tilt angle can not since four limb foot relative positions of double limb fixtures are fixed
Detent, fastening are carried out in the position of centre of gravity of steel plate blank.
If 3) in the non-gravity position biggish steel plate blank of handling tilt angle by force, due to steel plate blank be self-possessed it is larger,
Its gravity is much larger than the frictional force that four limb feet apply steel plate blank in the component of inclined direction, and sliding base accident easily occurs.
It is found through being retrieved to existing literature, under complex working condition, especially for the plate slab of the excessive stacking of tilt angle
Expect that the current application study of hoist tool is less." the slab clamp that Chen Kefei is delivered in " handling machinery " (in November, 2010)
Crane falls base crash analysis and clamp and improves " in a text, it is indicated that the main reason for sliding base is fallen, and to conventional plate blank handling
The clamp of fixture is improved.However, improved hoist tool working method remains horizontal clamping, for tilt angle
Excessive, the irregular handling for stacking plate remains unchanged no good technology solution.
