The invention provides an
elevator multi-fold door
operator device. The
elevator multi-fold door
operator device comprises a door operator base plate
assembly (1), a driving motor (2), a main belt
pulley assembly (3), a main synchronous belt (4), at least one secondary synchronous belt, at least one secondary belt
pulley assembly, door sheets and a door operator sill (5), wherein at least one side of a door operator body is provided with at least two door sheets, the door operator base plate assembly (1) comprises a door operator base plate (1.1), one end of the main synchronous belt (4) surrounds the driving motor (2), the other end of the main synchronous belt (4) surrounds the main belt
pulley assembly (3), one end of the secondary synchronous belt surrounds the driving motor (2) or the main belt pulley assembly (3), the other end of the secondary synchronous belt surrounds the secondary belt pulley assembly, the drive speed of the secondary synchronous belt is different from that of the main synchronous belt (4), the top ends of the door sheets are connected to the main synchronous belt (4) or the secondary synchronous belt, and the door sheets on the same side are different in operation speed. According to the
elevator multi-fold door
operator device, the structure is simple, reinforcing
processing can be carried out on guide rails due to the fact that a space is provided, use is safe,
energy consumption is low, and the service life is long.
