A kind of overhead track crane
The utility model relates to vehicle for construction technical field, is specially a kind of overhead track crane.
Existing overhead track crane adopts brigade steel to be connected and fixed aloft, form a monorail, at both sides U-shaped frame, quaternate walking wheels are installed, each road wheel between two relative to before and after rotate clamping in orbit, a suspension bracket is connected with in U-shaped frame bottom, suspension bracket is provided with electric block and fixed pulley, suspension hook is arranged at suspension bracket bottom, the overhead track crane of this monorail, due to the power of electric block and the intensity of single track less, can only carry the object of general weight, just helpless to large-scale overweight object, range of use is restricted.
Utility model content
The purpose of this utility model is to provide a kind of overhead track crane, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of overhead track crane, comprise pin, limit switch, change speed gear box, electric block, movable motor, elevated guideway, walking wheels, suspension bracket, travelling car, girder, control setup, suspension hook and connecting element, described movable motor is provided with change speed gear box, the rotating shaft of described movable motor is provided with walking wheels, described elevated guideway is between walking wheels, and elevated guideway is fixed on the column of suspension bracket, described electric block is positioned at above the middle part of suspension bracket, the both sides of described electric block are provided with limit switch, described travelling car is arranged on suspension bracket, described girder is connected with suspension bracket by steel rope, described suspension hook is fixed on the middle part of girder by pin, described suspension hook is provided with the connecting element of slip-off preventing, described control setup is arranged on girder.
Preferably, the built on stilts two-orbit that two tracks that described elevated guideway is fixed by parallel side-by-side form.
Preferably, the fixed pulley that can connect electric block is provided with in the middle part of described suspension bracket.
Preferably, described suspension hook is provided with the hook with safety tong preventing object from coming off.
Compared with prior art, the beneficial effects of the utility model are: this overhead track crane, compact conformation, use flexibly, factory building upper space conveying object can be effectively utilized to appointed place, can use the general object of electric block lifting, the power of motor that can promote again electric block carrys out the large-scale heavy object of lifting, reaches multiduty effect.
