Crane capable of stably assembling and disassembling precision mold

Abstract

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.

Description

technical field [0001] The invention relates to the technical field related to cranes, in particular to a crane capable of stably disassembling and assembling precision molds. Background technique [0002] The production method of producing products through precision mold injection has become the production method of most complex products. However, due to the heavy weight of the mold, it is very inconvenient to disassemble and install on the injection molding machine. Very unstable, the mold is easy to shake in the air, there is a risk of falling, and because the mold is too heavy, the general small lifting structure is prone to failure, which indirectly increases the risk of mold falling, and the cost of a large crane is too high, so it is necessary to A crane capable of stably lifting precision molds is designed to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a crane capable of stably disassembling and as...
