The invention discloses a crane capable of stably assembling and disassembling a precision mold. The crane comprises a machine body. The bottom surface of the machine body is fixedly provided with tworight-and-left symmetrical supporting columns. The bottom surfaces of the supporting columns are provided with two front-and-rear symmetrical moving wheels in a rotating mode. The interior of the machine body is provided with a lifting chamber with a downward opening. A lifting shaft is arranged between the left and right walls of the lifting chamber in a rotating mode. The periphery of the lifting shaft is fixedly provided with a lifting rolling cylinder. The periphery of the lifting rolling cylinder is fixedly provided with lifting spiny blocks and a lifting chain. By adopting a buckled connection between the lifting chain and the lifting spiny blocks, the crane capable of stably assembling and disassembling the precision mold can avoid the problem that a hanging rope slides when lifting due to the smooth surface of the lifting rolling cylinder in the lifting process of the lifting chain. At the same time, the crane can avoid the problem of crane failure and mold drop caused by a heavy mold in the lifting process by adopting ratchet restriction and clamping emergency braking, which greatly improves the lifting safety effect.

    本发明公开了一种能够稳定拆装精密模具的起重机,包括机体,所述机体的底面固设有两个左右对称的支撑柱,所述支撑柱的底面转动设有两个前后对称的移动轮,所述机体内设有开口向下的起重腔,所述起重腔的左右壁间转动设有起重轴,所述起重轴的外周上固设有起重滚筒,所述起重滚筒的外周上固设有起重刺块,所述起重滚筒的外周上固设有起重链条,本发明采用链条和刺块的卡扣连接方式,能够防止链条在起重过程中,由于滚筒的光滑表面导致吊绳起重打滑的问题产生,同时,采用棘轮限制以及夹紧刹车紧急制动两种方式,能够极大的提升起重过程中由于模具过重。
