The invention discloses an electric chain hoist, and relates to the technical field of hoisting devices. The electric chain hoist comprises a lifting hook frame, chains, a swing mechanism and a wallboard; the swing mechanism comprises a guide wheel frame and guide wheels; the guide wheel frame is of a symmetrical structure; a rotary connecting structure is arranged between the guide wheel frame and the lifting hook frame; the joint of the rotary connecting structure is located on the symmetry axis of the guide wheel frame; the guide wheels are rotationally connected to the two symmetrical ends of the guide wheel frame; the wallboard is provided with guide grooves; the guide grooves are matched with shafts of the guide wheels to form limiting structures; and the shafts of the guide wheels are connected to the wallboard in a sliding manner. The electric chain hoist has the following beneficial effects that (1), interference between the guide wheels on the load side and the hoisting chains is avoided, and abnormal abrasion of the chains and damage to the guide wheels are prevented; (2), the guide wheels on the non-load side can be closer to the hoisting chains, the chains and chain wheels can be better engaged, and chain climbing is prevented; and (3), the chains on the two sides of the electric hoist can be hoisted, the work efficiency is improved, and energy consumption is reduced.
本发明公开了一种环链电动葫芦,涉及起重装置技术领域,包括吊钩架、链条、摆动机构和墙板,所述摆动机构包括导轮架和导轮,所述导轮架为对称结构,所述导轮架和所述吊钩架之间设有转动连接结构,所述转动连接结构的连接处位于所述导轮架的对称轴上,所述导轮转动连接于所述导轮架的对称的两端;所述墙板设有导槽,所述导槽与所述导轮的轴配合形成限位结构,所述导轮的轴滑动连接于所述墙板。具有如下有益效果:(1)避免负载侧导轮与起重链条干涉,防止链条非正常磨损和导轮损坏;(2)使非负载侧导轮能更靠近起重链条,让链条和链轮啮合更好,防止爬链;(3)使电动葫芦两侧链条都能由于起重,提高了工作效率,降低了能耗。
