Description
Technical field
The present invention relates to the replacement operations of cold roll, hindering roller and fracture for handling more specifically to one kind
The suspender of roller.
Background technology
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 and hung time or so thousands of daily, wherein hindering roller rate according to 15%, time of roller is hindered in daily handling
Number will also be hung time or so up to a hundred, these, which are hindered roller mostly and are all, concentrates on the stage casing surface damage of working roll (working roll is convex roller
Roll-force suffered by stage casing is maximum).Existing frequently-used technology as shown in Figure 1, still using steel wire rope 1 bundle 2 both ends of working roll into
Row handling, it is at 45 ° between steel wire rope 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 stage casing 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 stage casing, institute's handling usage time is 20 minutes, is hung time or so by having 120 daily now
Hinder roller transport, the operating personnel that fracture injures lower section by a crashing object are 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 (things
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, working site has the working roll being largely broken, due to no sling point, all carried using artificial
To forklift, then be transported to truck platform with forklift and recycled, this process is inherently dangerous, again by pass through Gray you
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.
