The invention relates to an electric hoist which comprises a mounting seat and two motors fixed on the mounting seat. The two motors are coaxially and oppositely arranged, an output shaft of each motor is connected with a speed reducer, and output shafts of the two speed reducers are coaxially and fixedly connected with a winding drum; the upper end of a steel wire rope is fixed to the winding drum, and a hook is arranged at the lower end of the steel wire rope and used for hoisting heavy objects; a hook is arranged at the top of a mounting seat and is used for being connected with carrier equipment; power supply ports of the two motors are electrically connected in series with a main power supply in sequence, and a circuit breaker is electrically connected in series with the main power supply; and a remote controller is also included and is used for controlling forward rotation, reverse rotation and stopping of the motors, and the two motors act synchronously. According to the technical scheme, disassembly and assembly are convenient, double-motor driving is adopted, the balance performance in structure is better, the circuit breaker is used in a matched manner, when one motor breaks down, the circuit breaker cuts off the main power supply, the other motor is automatically braked due to power failures, and the safety coefficient is high.

    本发明涉及了一种电葫芦,包括安装座和固定在安装座上的2个电机,2个电机同轴相向设置,每个电机的输出轴处均连接有一个减速机,两个减速机的输出轴均与卷筒同轴固定连接;钢丝绳的上端固定在卷筒上,钢丝绳的下端设有吊钩,吊钩用于吊装重物;安装座的顶部设有挂钩,挂钩用于与载体设备连接;2个电机的供电口与总电源依次电性串联,总电源处电性串联有断路器;还包括遥控器,遥控器用于控制电机的正转、反转和停止,两个电机同步动作;本技术方案拆装方便,采用双电机驱动,在结构上平衡性能更佳,匹配使用断路器,当其中一个电机出现故障时,断路器切断总电源,另一个电机则因断电而自动制动,安全系数高。
