The invention discloses a six-lifting-chain chain hoist capable of adapting to high-precision quick ascending and descending. The six-lifting-chain chain hoist comprises a main machine body and a windlass mechanism; the windlass mechanism comprises a second upstream wheel axle, a first upstream wheel axle, a second upstream wheel, a first upstream wheel, a downstream wheel axle, a downstream wheelI, a downstream wheel II and a downstream wheel III, wherein the second upstream wheel axle and the first upstream wheel axle are parallelly arranged in a front-back staggered mode, and the downstream wheel I, the downstream wheel II and the downstream wheel III are arranged side by side; the two upstream wheel axles are arranged on bridging plates on the lower portion of a main wallboard, the downstream wheel axle is centrally fixed to a hook housing plate, the two upstream wheel axles are perpendicular to the shaft axis space of the downstream wheel axle, and the reference diameter of eachdownstream wheel chain ring groove is equal to the distance between central planes, for allowing lifting chains to be engaged, of the first upstream wheel and the second upstream wheel; the distance between axle hole centers of the first upstream wheel and the second upstream wheel is equal to the distance between central planes, for allowing lifting chains to be engaged, of the adjacent downstream wheels; after the lifting chains in transmission connection with the main machine body are wound around the downstream wheel I, the first upstream wheel, the downstream wheel II, the second upstreamwheel and the downstream wheel III, the heads of the lifting chains are hung on the bridging plates, the formed six lifting chains are vertically stressed and do not skew, and the engagement precision is higher than that of quick ascending and descending.

    本发明公开了可适应高精度快速升降的六行起重链环链葫芦,包括主机体和卷扬机构,该机构包括前后错位平行的第二、第一上游轮轴、第二、第一上游轮,及下游轮轴、并排的下游轮I、II、III,二上游轮轴分设于主墙板下部的桥接板上,下游轮轴居中固定在钩架板上,二上游轮轴分别与下游轮轴呈轴心线空间垂直,各下游轮链环槽分度圆直径等于第一、第二上游轮各自供起重链条啮合处中心平面的间距;第一、第二上游轮的轴孔中心间距等于相邻下游轮各自供起重链条啮合处中心平面的间距,传动连接主机体的起重链条卷绕下游轮I、第一上游轮、下游轮II、第二上游轮和下游轮III后,链环头端挂于桥接板,构成的六行起重链垂直受力不扭斜,啮合精度高适于快升降。
