Tower crane motor assembly use from locking-type upset hoist

The utility model relates to a tower crane motor assembly use from locking-type upset hoist, characterized by: including turbine worm reducer, turbine worm reducer's worm is by motor drive, the power of turbine worm reducer's turbine passes through second grade reducing gear mechanism and drives the sprocket, and the chain takes turns to to hang has the chain, and two ends of chain all are connected with the couple. The utility model has the advantages of the utility model discloses when lifting by crane, the both ends lug of tower crane motor is hung by two couples, directly hoists tower crane motor level, has avoided tower crane motor tip and surface phase contact collision, has protected the precision of equipment. During unsettled assembly, can be according to the position requirement of installing component, the orientation and the turned angle of control sprocket can realize the nearly 180 degree rotations of tower crane motor in vertical plane, like this the intensity of labour with regard to having reduced the assembler greatly. In addition, the self-locking function of worm and wormwheel reduction gear not only can keep the upset state, has also guaranteed the security simultaneously.
