detailed description

Referring to Fig. 1, Fig. 2 and Fig. 3, the special spreader for grinding rollers of the present utility model includes right splint 2, left splint 1, front guardrail 3, and rear guardrail 7; right splint 2 and left splint 1 top pass pin 6 are hinged, and are respectively arranged on the left and right sides of the spreader. The cooperation between the left splint 1 and the right splint 2 and the pin shaft 6 is a clearance fit, and the opposite sides of the lower parts of the left and right splints are adapted to the outer circle of the grinding roller. Arc-shaped, handles 11 are provided on the outside of the lower part of the right splint and the left splint; the front and rear guardrails are arranged symmetrically, and are arc-shaped to match the outer circle of the grinding roller. One end of front guardrail 3 and rear guardrail 7 is respectively installed on the both sides of left clamping plate bottom by hinge, and front guardrail 3 and rear guardrail 7 other ends are respectively fixed on the both sides of right clamping plate 2 bottoms by fixing pin 4. The cooperation between the bearing pin 6 and the left and right clamping plates is clearance fit. There are altogether six ejection bolts 5, and there are three reinforcing ribs 8 between the front and rear side plates of the left and right splints.

As shown in Figure 1, the right splint and the left splint are herringbone splints, each herringbone splint includes a front side plate 9 and a rear side plate 10, the upper parts of the front side plate 9 and the rear side plate 10 are connected in parallel, and the front side The end of the plate 9 and the rear side plate 10 is fixed through the bottom plate 12, and the middle part of the front side plate 9 and the rear side plate 10 is fixed through the horizontal reinforcing rib 8, and the ejection bolt 5 on the reinforcing rib 8 It is used to eject the grinding roller when dismounting the grinding roller from the grinding roller spreader. It is simple and labor-saving for workers to operate, and it is safer and more reliable. One end of the front guardrail 3 is installed on the outside of the herringbone left splint front side plate 9 bottom by a hinge, and one end of the rear guardrail 7 is installed on the outside of the herringbone left splint rear side plate 10 bottom by a hinge; The other end of column 3 is fixed on the outside of right clamping plate front side plate 9 bottoms by fixing pin 4, and the other end of rear guardrail 7 is fixed on the outside of right clamping plate rear side plate 10 bottoms by fixing pin 4.
