[0017] Reference Figure 1 The utility model discloses a dual-mode electric crank for a switch machine, comprising a power supply assembly, a motor and a transmission assembly and a control assembly arranged on a housing 10. The motor and the transmission assembly comprise an AC / DC dual-purpose motor 14 and a self-tightening sleeve chuck 11. The AC / DC dual-purpose motor 14 forms a transmission connection with the self-tightening sleeve chuck 11 through a transmission shaft, a transmission control assembly 13 and a torque regulator 12. A switch machine sleeve 30 can be detachably mounted on the self-tightening sleeve chuck 11, and the switch machine sleeve 30 is connected to the rotating shaft of the switch machine. The function of the transmission control assembly 13 is to disconnect the transmission connection when the torque exceeds a set value.
[0018] Reference Figure 1 The power supply assembly includes a battery pack 20 and an AC power supply port 19 electrically connected to the AC / DC dual-purpose motor 14. The battery pack 20 outputs 24V DC power, and the AC power supply port 19 receives 220V AC power. The control assembly includes a forward and reverse control switch 15 and a speed switch 16. The forward and reverse control switch 15 is used to control the forward and reverse rotation of the AC / DC dual-purpose motor 14. The speed switch 16 controls the speed of the AC / DC dual-purpose motor 14 through the speed switch control assembly 18 and the continuously variable transmission 17.
[0019] The AC / DC dual-purpose motor 14 has AC and DC dual-standard input voltages, can accept DC 24V and AC 220V inputs, and can be powered by a portable battery pack and a switch machine AC 220V maintenance power supply. The motor is brushless, noiseless, long-life, and maintenance-free.
