The ㈠ technical field: the utility model relates to logistics load transfer device technical field, the fast quick change duct device of especially a kind of electric monorail overhead chain conveyer.
The ㈡ background technology: EMS electric monorail overhead chain conveyer system is for realizing the process requirements of the multiple variation of circuit that logistics is carried, usually adopt electric pushrod to change duct device, it includes fixed frame and cooperates the movable frame of slip with fixed frame, movable frame is provided with movable straight rail and movable curved rail, driver train is installed on fixed frame connects movable frame, this device is to adopt the steel structure lead frame, electric pushrod is as actuating unit power, exist the making precision low, the push rod contraposition is not accurate, speed is low, be difficult for shortcomings such as installation and maintenance, and the steel structure support interval of whole framework is bigger, for guaranteeing frame strength, must strengthen frame size, guide rail on the fixed frame is the upper surface of design at crossbeam on the other hand, the movable frame walking is on the top of fixed frame, and structure is huge, and it is big to take up room, and operation scheme is stable inadequately, has become the bottleneck of restriction EMS system widespread use.
The ㈢ summary of the invention: problems such as the purpose of this utility model will solve existing electric pushrod exactly, and to change duct device speed low, be difficult for installation and maintenance, and steel structure frame weight is big, and it is big to take up room provide a kind of electric monorail overhead chain conveyer fast quick change duct device.
Concrete scheme of the present utility model is to change duct device and improve at existing, it includes fixed frame and cooperates the movable frame of slip with fixed frame, movable frame is provided with movable straight rail and movable curved rail, driver train is installed on fixed frame connects movable frame, it is characterized in that: described driver train includes motor and retarder, one rocking bar is installed on the output shaft of retarder, and the outer end of rocking bar is connected with movable frame by a connecting rod.
Movable straight rail described in the utility model and movable curved rail adopt some blocks of C shape plates to be lifted on the movable frame respectively.
For reducing weight, make compact conformation, reliable, movable frame described in the utility model and fixed frame are to adopt the high strength alumin ium alloy section bar to make, the inboard design of described fixed frame left and right sides crossbeam has guide-track groove, the outside of described movable frame left and right sides crossbeam is equipped with at least two road wheels, and all road wheels place the guide-track groove of fixed frame left and right sides crossbeam to walk.
For guaranteeing that movable frame operates steadily, reduce noise, four jiaos at movable frame described in the utility model are equipped with four track adjusting wheels; And described road wheel and the track adjusting wheel that is installed on the movable frame is surrounded by layer of polyurethane outward.
Install for convenient construction, optimize structure, the proof strength expendable weight, on four crossbeams of fixed frame described in the utility model in the upper surface or three designs of the upper and lower end and the outside T slot is arranged.
The utility model adopts Rocker Driving Mechanism, the operation lane change (be about in this device movable straight rail or movable bend rail as required with the orbital docking of sending a car, seesawing by straight rail of movable frame drive activity and movable curved rail and to realize lane change) speed is enhanced about more than once, reliable operation, long service life, convenient for installation and maintenance, adopt high strength alumin ium alloy framework and side guide groove structure, in light weight, the intensity height, installation is convenient, movable frame and fixed frame can be arranged at grade, compact conformation, and it is little to take up room, safe in operation, steadily, can be widely used in construction machinery and equipment, automobile, on the automatic production line of industries such as light industry.
