The invention provides an electric hoist with protection buttons, and belongs to mechanical hoisting devices. The electric hoist solves the problems that a protection device in an existing electric hoist is single in structure, a lifting hook can still rush against and collide with the electric hoist under the condition of serious misoperation, and then high-intensitive damage to a machine is caused. The electric hoist with the protection buttons comprises a motor, a speed reducer, a guide frame, a chain bucket, a chain, a lifting hook, a handle switch assembly, a shell and a controller arranged in the shell, wherein one end of the chain passes through and penetrates out of the guide frame to be connected with the lifting hook, the other end of the chain is placed in the chain bucket, thefirst electronic limiting button and the second electronic limiting button are arranged at the positions, close to the guide frame, of the shell, the end, connected with the lifting hook, of the chainis sleeved with a first electronic limiting piece, and the end, connected with the chain bucket, of the chain is sleeved with a second electronic limiting piece. The electric hoist has the advantagesthat the structure is simple, the operation is convenient and the protection effect on the electric hoist is good.

    本发明提供了一种带有保护按钮的电动葫芦,属于机械起重设备。它解决了现有电动葫芦中的保护装置结构构造单一,在严重操作不当的情况下可能还是会使吊钩冲顶撞向电动葫芦,造成机器高强度的损坏的问题。本带有保护按钮的电动葫芦,包括电机、减速机、导向架、链桶、链条、吊钩、手柄开关总成、壳体和装于壳体内的控制器,链条一端经过并穿出导向架外与吊钩连接,另一端放置于链桶内,壳体上靠近导向架的位置处设置有电子限位按钮一和电子限位按钮二,链条连接有吊钩的一端上套装有电子限位件一,链条连接有链桶的一端上套装有电子限位件二。本发明具有结构简单,操作方便且对电动葫芦保护效果好的优点。
