Description

Simple and easy bayonet device of lifting by crane anticreep cardboard Technical Field The utility model relates to the technical field of lifting of moulds, in particular to a simple and easy plug-in type device for lifting an anti-drop clamping plate. Background In the use of moulds, it is often necessary to transport the moulds, and lifting is usually performed by using lifting bars and lifting lugs for the transport of the moulds. Because the volume of mould is generally great, has certain weight, and the weight of some moulds is even more than several tons, when transporting the mould, once lift by crane the stick slippage and cause the mould to fall down, can lead to serious safe production trouble, the result can't be assumed, current lifting rod anti-drop structural design factor of safety is lower, the lifting rod moves back and forth in the mould under the mould lifting stress and takes place to drop easily, there is latent safety to hide, therefore proposes a simple and easy male device that lifts by crane anti-drop cardboard, solves this problem. The utility model discloses an anti-drop lifting rod for transferring a die, and relates to the technical field of die lifting. The anti-drop ring sleeve is sleeved on the large-diameter section of the stepped assembly part, the internal thread sleeve is in threaded fit with the small-diameter section of the stepped assembly part, the hanging rod installation difficulty is reduced in the early stage of hanging rod process design, the falling probability of the hanging rod is reduced, and the safety coefficient is improved, but the improvement of the production process of the hanging rod which needs to be changed is high in production cost requirement, high in price and low in universality, and is unfavorable for large-scale production and use.
