The vertical hoist that lifts by crane of circular panel that can solve above-mentioned technical problem, its technical scheme includes stone tongs, the institute difference is stone tongs is including installing in the last chuck of rings bottom, the bottom of going up the chuck is preceding, the back seted up wear to establish the hole and can with the draw-in groove of circular panel top buckle, the upper end of roll adjustment screw rod is installed in the wear to establish the hole of last chuck with the rotation mode, the roll adjustment screw rod is gone up to revolve and is closed the roll adjustment nut, be equipped with the left branch strut down tube and the right branch strut down tube of symmetry on the roll adjustment nut, left branch strut down tube lower extreme rear portion and right branch strut down tube lower extreme rear portion articulate respectively and are equipped with left chuck and right chuck, left side chuck top is seted up the draw-in groove that can with circular panel left lower part buckle, right side chuck top is seted up the draw-in groove with circular panel right lower part buckle.
Furthermore, in order to match the radian of the circumference of the circular plate, the clamping grooves are arc-shaped grooves.
The utility model has the advantages that:
1. the utility model discloses the vertical hoist and mount that lifts by crane of circular panel can effectively carry out vertical hoist and mount to circular panel, especially when processing circular panel on horizontal boring and milling machine, can save the assistance-time of hoist and mount and clamping by a lot.
2. The utility model discloses simple structure, convenient operation, factor of safety is high, can be applicable to the hoist and mount to the circular panel of different specification sizes.

Detailed Description
The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.
The utility model discloses vertical lifting device of circular panel, including stone tongs, stone tongs includes chuck 2, left chuck 7 and right chuck 8 and roll adjustment screw rod 3 and roll adjustment nut 4.
The upper chuck 2 is welded with a hanging ring 1, a through hole and an arc-shaped clamping groove (the radian is matched with the circumference of a circular plate 9, the width is matched with the thickness of the circular plate 9) are formed in the front and back of the bottom of the upper chuck 2, and the central position of the arc-shaped clamping groove is upwards aligned with the hanging ring 1; the polished rod of the upper end of the distance adjusting screw rod 3 is installed in a rotating mode in a penetrating hole of the upper chuck 2, the distance adjusting nut 4 is screwed on a screw rod of the distance adjusting screw rod 3, a left supporting inclined rod 5 and a right supporting inclined rod 6 which are symmetrical left and right are welded on the distance adjusting nut 4, the left chuck 7 is hinged with a rod body at the rear part of the lower end of the left supporting inclined rod 5, an arc-shaped clamping groove (the radian matches the circumference of the circular plate 9 and the width matches the thickness of the circular plate 9) is formed in the top part of the left chuck 7, the right chuck 8 is hinged with the rod body at the rear part of the lower end of the right supporting inclined rod 6, and the arc-shaped clamping groove (the radian matches the circumference of the circular plate 9 and the width matches the thickness of the circular plate 9) is formed in the top part of the right chuck 8, as shown in fig. 1 and fig. 2.
FIG. 3 shows for adopt the vertical circular panel 9 of phi 1200mm that lifts by crane of stone tongs, it passes through arc draw-in groove buckle in the top of circular panel 9 to go up chuck 2, left side chuck 7 passes through arc draw-in groove buckle in the left lower part of circular panel 9, right side chuck 8 passes through arc draw-in groove buckle in the right lower part of circular panel 9, it adjusts pitch nut 4 on the screw rod 3 to rotate the roll adjustment, through the taut effect of left branch stay down tube 5 and right branch stay down tube 6, make left side chuck 7 and right chuck 8 and last chuck 2 press from both sides tight circular panel 9 together.
FIG. 4 is a circular plate 9 with diameter phi 1950mm vertically lifted by using a hoisting fixture, because the diameter of the circular plate 9 with diameter phi 1950mm is larger than that of the circular plate 9 with diameter phi 1200mm in FIG. 3, the position of the pitch adjusting nut 4 is adjusted by rotating the pitch adjusting screw 3, so that the clamping range of the upper chuck 2 and the left chuck 7 and the right chuck 8 is matched with the circumference of the circular plate 9 with large diameter, after the pitch adjusting nut 4 is adjusted to be in place, the upper chuck 2 is buckled at the top of the circular plate 9 through an arc-shaped clamping groove, the left chuck 7 is buckled at the left lower part of the circular plate 9 through the arc-shaped clamping groove, the right chuck 8 is buckled at the right lower part of the circular plate 9 through the arc-shaped clamping groove, the pitch adjusting nut 4 is adjusted by rotating the pitch adjusting screw 3, and the circular plate 9 is tightly clamped by the left support diagonal rod 5 and the right support diagonal rod 6, so that the left chuck 7 and the right chuck 8 and the upper chuck 2 clamp the circular plate 9 together.
