Description

Technical Field

[0001] The utility model relates to the technical field of crucible lifting, in particular to a lifting device for graphite crucible pressed products. Background Art

[0002] Since the surface of graphite crucible pressed products is relatively soft when they are not completely cooled, this brings certain difficulties to the reverse transportation. The existing hoists can easily scratch the top of the graphite crucible pressed products, and there is no limit on the lifting, which makes it very inconvenient to take and put. The graphite crucible pressed products are upright after being finished, so it is necessary to design a practical hoist. When reversed, it is also necessary to ensure that the products are upright to ensure that the lifting in daily production does not damage the products. Utility Model Content

[0006] Preferably, the upper right clamping plate and the lower left clamping plate are double-layer plate structures, and the lower right connecting plate and the upper left connecting plate are respectively arranged between the upper right clamping plate and the lower left clamping plate.

[0007] Preferably, the left pulley mechanism includes a limit rod and a bearing, one end of the limit rod is fixedly connected to the upper part of the left clamp arm, and the other end is fixedly connected to the bearing, and the right pulley mechanism has the same structure as the left pulley mechanism and is arranged opposite to each other.

[0008] Preferably, the inner side of the hoop block is a wave-shaped structure, and its contour is the same as the outer contour of the graphite crucible.

[0009] Preferably, the inner wave-shaped structure of the hoop block protrudes outward at two locations, and the two hoop blocks are arranged opposite to each other and can clamp two graphite crucibles at the same time.

[0010] Preferably, a lining block is further provided at the inner side of the hoop block where it contacts the graphite crucible.

[0011] Preferably, the lining block is made of polyurethane.

[0012] The beneficial effects of the utility model are:

[0013] The utility model makes the graphite crucible pressing products stand upright after they are finished, and can ensure that the products are upright during inversion. Limit rods and bearings are provided to limit the graphite crucible during lifting and transportation, and prevent the top of the graphite crucible from being damaged during lifting and transportation. Hanging chains and limit pins are provided to limit the opening and closing degree of the lifting device, which is convenient for unloading the graphite crucible and prevents the lifting device from being unable to be closed and removed during disassembly or causing damage to the graphite crucible during unloading.
