Description
Technical field
The present invention relates to the replacement operations of cold roll, hurt roller and fracture for handling more specifically to one kind
The suspender of roller.
Background technique
Currently, to provide the use of several rolling main lines of various models in the cold rolling grinding roller workshop of some large iron and steel enterprises
Roller has enough to meet the need the handling number of roll daily and hangs time or so thousands of, wherein hurting roller rate according to 15%, time of roller is hurt in daily handling
Number will also be hung time or so up to a hundred, these, which are hurt roller mostly and are all, concentrates on the middle section surface damage of working roll (working roll is convex roller
Roll-force suffered by middle section is maximum).Existing frequently-used technology as shown in Figure 1, still using wirerope 1 bundle 2 both ends of working roll into
Row handling, it is at 45 ° between wirerope 1 and working roll 2, when handling 2 both ends of working roll by handling power, be by mechanical analysis there are two types of
Power, as vertical stress component and horizontal component (direction of arrow in Fig. 1), wherein the weight institute of vertical stress component and working roll 2 itself
Offset, and horizontal component can not be eliminated, and the horizontal component at both ends is concentrated in 2 middle section of working roll, on 2 middle section position of working roll if any
Crack will then spread along crack, working roll 2 is caused integrally to be broken during handling.Existing lifting working rolls are for safety
It avoids shaking the power caused by working roll middle section, institute's handling is 20 minutes using the time, by having 120 to hang time or so daily now
Hurt roller transport, the operator that fracture injures lower section by a crashing object is possible to during working roll handling, by Gray's that mother law to scene
Danger source assessed, as D=L (possibility of causing danger score) * E (coming across the score in hazardous environment) * C (thing
Therefore occur after possible outcome score), obtain D=3 (possibility) * 6 (working in dangerous environment daily) * 7 (severe injury)=
126, identification result is secondary threat source.
In addition, there is the working roll being largely broken in working site, due to no sling point, all using manual handling
To forklift, then truck platform being transported to forklift and is recycled, this process is inherently dangerous, equally by passing through Gray's that
Mother law assesses the danger source at scene, obtains D=3 (possibility) * 6 (working in dangerous environment daily) * 3 (severe injury)
=4, identification result is level Four danger source.
