The invention discloses a leading chain of a chain hoist, which is integrally formed by a flexible base strip, rigid guide bulges and rigid slip rings, the guide bulges are uniformly formed on the surface of the base strip at intervals, the slip rings are formed on the guide bulges and are vertical to each other in pairs, and a tail slip ring positioned at the bottom end of the base strip is used for being connected with a lifting chain. The invention further provides a matching structure of the guide chain and the guide chain frame with the lifting chain wheel, the guide chain frame is of an integrated structure, a containing cavity is formed in the upper portion of the guide chain frame, a guide chain frame chain inlet hole and a guide chain frame chain outlet hole which are communicated with the containing cavity are formed in the lower portion of the guide chain frame, and guide chain frame arc-shaped grooves are formed around the guide chain frame chain inlet hole, the guide chain frame chain outlet hole and the containing cavity. The hoisting chain wheel is positioned in the accommodating cavity; the sliding ring is in sliding fit with the chain guide frame chain inlet hole and the chain guide frame chain outlet hole, and the guide protrusion is in sliding fit with the chain guide frame arc-shaped groove. The slip ring is adaptively engaged with a chain nest of the hoisting chain wheel, and the base strip is adaptively matched with a chain ring groove of the hoisting chain wheel. And the requirement of guiding and assembling the lifting loop chain is met.

    本发明公开了一种环链葫芦的引链,由挠性的基条、钢性的导引凸起和钢性的滑环一体组成,导引凸起间隔均匀成形在基条表面,滑环成形于各导引凸起且二二相互垂直,位于基条底端的尾滑环用作与起重环链链条连接。还提供了引链与带起重链轮的导链架的配合结构,导链架为一体结构,上部开容纳空腔而下部分设有连通容纳空腔的导链架进链孔、导链架出链孔,围绕导链架进链孔、导链架出链孔和容纳空腔布置有导链架弧形沟槽,起重链轮位于容纳空腔内;滑环与导链架进链孔、导链架出链孔分别滑动配合,导引凸起与导链架弧形沟槽呈滑动配合;滑环自适应地啮合起重链轮的链窝,基条自适应地与起重链轮的链环槽适配。实现了引导装配起重环链链条的需要。
