Embodiment
Below in conjunction with accompanying drawing and by embodiment, the technical solution of the utility model is described further.
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, the formula double hook driving of a kind of plating line gantry comprises driving frame 1, hoisting appliance and travel mechanism, described hoisting appliance is arranged at the top of described driving frame 1, it comprises two spaced spools 2 and two lifting motors 3, described lifting motor 3 is connected by shaft coupling with corresponding spool 2, described spool 2 is provided with windlass structure, described windlass structure comprises two rolling drums 4 being arranged at intervals on described spool 2, described rolling drum 4 is connected with polyamide fibre band 5, the lower end of described polyamide fibre band 5 connects the lifting rod 7 for promoting cathode rod 6. described travel mechanism is arranged in the driving frame 1 below described hoisting appliance, it comprises movable motor 8 and two spaced transmission shafts 9, on the output shaft of described movable motor 8 and a transmission shaft 9 wherein, correspondence is provided with between synchronous belt wheel 10, two synchronous belt wheels 10 to connect synchronous band 11.
The two ends of two transmission shafts 9 are in transmission connection by rack and pinion assembly 12, and described rack and pinion assembly 12 comprises the gear being arranged at described transmission shaft 9 two ends, and corresponding gear is fixed with tooth bar in described driving frame 1.
Above-mentioned driving mechanism mainly realizes the motion that cathode rod about 6 promotes two degree of dimension of walking with front and back. When cathode rod about 6 promotes, two lifting motors 3 rotate, transmit power on spool 2 by shaft coupling, and then drive rolling drum 4 to rotate, one section of polyamide fibre band 5 is fixed in rolling drum 4, the other end is fixed on lifting rod 7, and rolling drum 4 is rotated polyamide fibre band 5 around upper or put down, it is achieved the up and down motion of lifting rod 7. When walking before and after cathode rod 6, movable motor 8 rotates, transmission shaft 9 is driven to rotate by synchronous belt drive mechanism, gear is equipped with at transmission shaft 9 two ends, tooth bar is fixed in the frame of production plant, rack and pinion assembly 12 realizes the forward-reverse motion of whole driving, thus reaches the motion of cathode rod 6 forward-reverse.
Above embodiment has just set forth ultimate principle of the present utility model and characteristic; the utility model does not limit by above-mentioned example; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various change and change, and these changes and change all fall within the scope of claimed the utility model. The claimed scope of the utility model is defined by appending claims and equivalent thereof.
