Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1, the graphite crucible hoisting device provided in this embodiment includes a fixed frame 1, an air pressure telescopic rod 2 disposed in the middle of the fixed frame 1, a plurality of inner support bars 3 disposed around the lower end of the fixed frame 1 and hinged to the fixed frame 1, a taper disc 4 hinged to the lower end of the air pressure telescopic rod 2 and used for expanding the inner support bars 3 under the traction of the air pressure telescopic rod 2, and a hoisting ring 5 hinged to the top end of the fixed frame 1; when the air pressure in the air pressure telescopic rod 2 is adjusted, the air pressure telescopic rod 2 drives the taper disc 4 to ascend, the taper disc 4 props up the inner supporting rod 3 to enable the lower end of the inner supporting rod 3 to be tightly attached to the inner wall of the graphite crucible, and the graphite crucible can be hung by hanging the hoisting ring 5 by using a hoisting hook of a hoisting machine.
Further, the fixing frame 1 comprises an upper fixing plate 11, a lower fixing plate 12 and a connecting rod 13 for connecting and fixing the upper fixing plate 11 and the lower fixing plate 12; the upper fixing plate 11 is provided with a connecting lug 16 hinged with the lifting ring 5; a plurality of hinge lugs 14 are arranged on the lower fixing plate 12; the inner support bar 3 is mounted on the hinge lug 14 by means of a nut 15.
Further, the pneumatic telescopic rod 2 comprises a pneumatic cylinder 21, a telescopic rod body 22 and an air duct 23 which is arranged on the pneumatic cylinder 21 and used for changing the air pressure in the pneumatic cylinder 21 so as to enable the telescopic rod body 22 to extend and retract; one end of the air duct 23 is connected with the pneumatic cylinder 21, and the other end is connected with the air valve, so that the extension and the contraction of the telescopic rod body 22 can be controlled through controlling the inflation and air exhaust processes of the air valve, and the opening and the closing of the inner supporting rod 3 can be controlled by controlling the upper part of the conical disc 4.
