Description
Technical field
The utility model belongs to mill roll auxiliary tool technology field, is to be related to a kind of milling train support more specifically
Roller roll change stool.
Background technique
The roll change stool that milling train replaces support roller is the essential a part of milling train during replacing support roller, mainly
Effect places it on lower backing roll when being replacement support roller, for by the extraction and loading of upper backup roll.Due to more
Support roller tunnel is changed as deep as to 2.5 meters, remote apart from personnel's erect-position place, two wirerope are hung over difficulty above by operating personnel
Greatly, the time is long, causes very big difficulty to replacement support roller.
Currently, replacement support roller at least needs 3 operating personnels to work in coordination.Wherein a people takes instruction intercommunication to contact overhead traveling crane
Coordinating operation, remaining 2 personnel take 2 long hook to carry out coordinating operation, one end of wirerope are hung over to the suspension hook of overhead traveling crane first
On, then with long hook holder wirerope below upper beam around getting off, the other end of wirerope is suspended on the hook of overhead traveling crane, is made
Industry personnel need to stir long hook up and down and one end of wirerope is just hung over could reluctantly on the hook of overhead traveling crane, accuracy
Also not high, two wirerope can just be hung on the suspension hook of overhead traveling crane respectively twice by repeating operation, cause operating personnel's operation difficult
Degree is big, and danger coefficient is high, and working efficiency is low, and strong influence replaces the time of support roller.
Utility model content
The purpose of this utility model is to provide rolling mill roll change stools, to solve milling train existing in the prior art more
Change the technical problem that support roller operation difficulty is big, and roll changing time is grown.
In order to achieve the above purposes, the technical solution adopted by the utility model is: provide rolling mill roll change stool, including in
