Window cleaning equipment plain type lifting mechanism
Technical field
The utility model relates to a kind of window cleaning equipment assembly, particularly a kind of window cleaning equipment plain type lifting mechanism.
Background technology
Transmission between the reducing motor of existing window cleaning equipment lifting mechanism and reel is undertaken by chain or gear, and this indirectly phoresying by driving chain or gear, and kinetic equation loss is large, and driving chain or gear use rear fragile for a long time; In addition, the spacing employing of existing screw mandrel be screw mandrel limit switch, this screw mandrel limit switch structure is complicated, and security is low.
Summary of the invention
The purpose of this utility model designs a kind of window cleaning equipment plain type lifting mechanism.
To be solved in the utility model is that transfer motion power loss between the reducing motor of existing hoisting mechanism of window-cleaning machine and reel is large, driving chain or long-time fragile etc. the problem of gear.
For realizing the purpose of this utility model, this has the technical scheme of employing to be: it comprises casing, be located at the lifting mechanism in casing, described lifting mechanism comprises reducing motor, reel, Bidirectional-screw, rope skipping preventing mechanism and lead limit switch, described reducing motor rotating shaft is connected with spool shaft, the side of reel is located at by described Bidirectional-screw and lead limit switch, on described Bidirectional-screw, cover has screw, described screw is facing to lead limit switch, and described rope skipping preventing mechanism is located at the avris of reel.
The utility model has the advantages that: the utility model adopts reducing motor direct-drive reel, saves power, and structure is simple, and service time is long; Substitute screw mandrel limit switch by multi-functional lead limit switch simultaneously, make structure simple, safe and reliable.
