The invention relates to the technical field of electric hoists, and discloses an overload protection device for mechanical equipment, the overload protection device for the mechanical equipment comprises a shell, the top of the shell is fixedly connected with a hanging ring, the side wall of the shell is fixedly provided with a supporting plate, the top of the supporting plate is fixedly provided with a motor, and the top of the motor is fixedly provided with an overload protection device. A rotating shaft is fixed to the output end of the motor, and the end, away from the motor, of the rotating shaft is rotationally installed on the inner wall of the shell. According to the overload protection device for the mechanical equipment, when an object is hooked through a hook and is too heavy, through cooperation of a transmission spring, an extrusion rod, an inclined block and a connecting rod, the connecting rod can drive a limiting block to move out of a limiting groove, limiting of the hook can be relieved, then the hook is separated from a mounting column, and the hook cannot be continuously used; and therefore, a protection effect can be achieved, and certain safety risks caused by breakage of the steel rope due to the fact that the steel rope cannot bear the object when the object is lifted to a high position by the hook are prevented.
本发明涉及电动葫芦技术领域,且公开了一种用于机械设备的过载保护装置,该用于机械设备的过载保护装置,包括壳体,所述壳体的顶部固定连接有挂环,所述壳体的侧壁固定有支撑板,所述支撑板的顶部固定有电机,所述电机的输出端固定有转动轴,所述转动轴远离电机的一端转动安装在壳体的内壁。该用于机械设备的过载保护装置,当通过挂钩将物品钩起时,当物品过重时,通过传动弹簧、挤压杆、倾斜块和连接杆的配合,使连接杆可以带动限位块从限位槽中移出,可以解除对挂钩的限位,进而使挂钩从安装柱中脱离,使挂钩不能继续使用,进而可以起到保护的效果,防止挂钩将物品吊起到高处时,因钢绳承受不住,造成钢绳断裂,存在一定安全风险。
