Abstract
The present invention relates to a kind of method of hoisting rolling mill frame, it is characterized in that：Making one first is used for the equalizer bar of hoisting rolling mill frame, the main body of equalizer bar is the long beam of a symmetrical structure, it is symmetrical in main body to be provided with two hangers, the bottom of equalizer bar main body between two hangers is symmetrical to be hinged with two connecting plates, lifting-eye location bearing pin is provided with the bottom of connecting plate, the axostylus axostyle of lifting-eye location bearing pin is located at the inner side of connecting plate, and two lifting-eye location bearing pins are symmetrical；It is connected respectively with two hangers on equalizer bar with two overhead traveling cranes in frame main building, two lifting-eye location bearing pins on equalizer bar are made to be directed at the connecting hole of rolling-mill housing, and be connected with frame, then two overhead traveling cranes steadily hook up to sling frame simultaneously is installed to specified location.Its advantage is：Rolling-mill housing is lifted using equalizer bar, rolling-mill housing vertically can be steadily lifted by crane, hoisting process is quick, safe, accurate.
Description
Technical field
The present invention relates to a kind of method of hoisting rolling mill frame, belong to metallurgical machinery equipment installation field.
Background technology
The lifting operation of rolling-mill housing equipment can be usually run into milling equipment installation process, due to frame outside
The features such as shape size is big, monomer weight is big, must assure that frame vertical lifting, causes in addition in hoisting process
The lifting operation of rolling-mill housing is just relatively difficult, and the lifting operation of rolling-mill housing equipment was just installed into milling train
Emphasis and difficult point in journey.
The content of the invention
It is an object of the invention to provide a kind of side for the hoisting rolling mill frame that vertically can steadily lift by crane rolling-mill housing
Method.
Technical scheme is as follows：
Making one first is used for the equalizer bar of hoisting rolling mill frame, and the main body of equalizer bar is a symmetrical structure
Long beam, it is symmetrical in main body to be provided with two hangers, the equalizer bar main body between two hangers
Bottom is symmetrical to be hinged with two connecting plates, and lifting-eye location bearing pin, suspension centre are provided with the bottom of connecting plate
The axostylus axostyle of alignment pin is located at the inner side of connecting plate, and two lifting-eye location bearing pins are symmetrical；Use frame master
Two overhead traveling cranes in factory building are connected with two hangers on equalizer bar respectively, determine two suspension centres on equalizer bar
Position bearing pin is directed at the connecting hole of rolling-mill housing, and is connected with frame, and then two overhead traveling cranes are simultaneously steady rises
Frame is sling and is installed to specified location by hook.
It is an advantage of the invention that：Rolling-mill housing is lifted using equalizer bar, vertically can steadily lift by crane and roll
Machine frame, hoisting process is quick, safe, accurate.
Brief description of the drawings
Fig. 1 is the front view of equalizer bar；
Fig. 2 is the side view of equalizer bar；
Fig. 3 is the lifting schematic diagram of the present invention.
Embodiment
Embodiment：Roughing mill on certain iron and steel enterprise 2250mm hot rolling lines and finishing mill frame are lifted,
Specific method is as follows：
Referring to the drawings, one is made first is used for the equalizer bar 5 of hoisting rolling mill frame, the main body 1 of equalizer bar 5
It is the long beam of a symmetrical structure, it is symmetrical in main body to be provided with two hangers 2, between two hangers
Equalizer bar main body bottom it is symmetrical be hinged with two connecting plates 3, the bottom of connecting plate be provided with suspension centre
Alignment pin 4, the axostylus axostyle of lifting-eye location bearing pin is located at the inner side of connecting plate, and two lifting-eye location bearing pins or so
Symmetrically；The main body 1 of equalizer bar steel plate assembled welding fabrication, hanger 2 that 70mm is thick and 30mm is thick
It is made, is heat-treated after completing with the thick steel plates of 70mm；The 70mm thickness of connecting plate 3
Steel plate is made, and is heat-treated after completing；The diameter 180mm of lifting-eye location bearing pin 4 round steel
Processing and fabricating is formed.It is connected respectively with two hangers on equalizer bar with two overhead traveling cranes in frame main building,
Two lifting-eye location bearing pins on equalizer bar is directed at the connecting hole of rolling-mill housing 6, and be connected with frame,
Then two overhead traveling cranes steadily hook up to sling frame simultaneously is installed to specified location.
Roughing mill on certain iron and steel enterprise 2250mm hot rolling lines and finishing mill frame are hung using the above method
Pretend in industry, it is quick, safely, the lifting task of rolling-mill housing is accomplished accurately, and once lift successfully.
