Detailed description of the invention
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Fig. 1 Fig. 2, a kind of telescoping mechanism of pinion and-rack container spreader, comprises girder 1, front intermediate beam 2, rear intermediate beam 3, front beam 4 and back end beam 5.
Front intermediate beam 2 is arranged on the front end of girder 1, and the rear end of front intermediate beam 2 and girder 1 grafting also and between the front end of girder 1 form expansion fit, and front beam 4 is arranged on the front end of front intermediate beam 2 and forms expansion fit with front intermediate beam 2; Rear intermediate beam 3 is arranged on the rear end of girder 1, and the front end of rear intermediate beam 3 and girder 1 grafting also and between the rear end of girder 1 form expansion fit; Back end beam 5 is arranged on the rear end of rear intermediate beam 3 and forms expansion fit with rear intermediate beam 3; Girder 1 is provided with motor and motor reducer 8, between motor reducer 8 and end carriage, is provided with gear, rack gear.
There are two kinds of structures in gear, rack gear:
The first structure, gear, rack gear are: motor reducer 8 is the device that reduces starter of the binary shafts, and two output revolving shafts of motor reducer 8 are respectively arranged with gear 9, and two gears 9 are positioned at the both sides of girder 1; Be provided with the both sides that two front tooth bars, 6, two front tooth bars 6 are symmetrically distributed in girder 1 between front beam 4 and two gears 9, before two, the front end of tooth bar 6 is connected with front beam 4, and before two, the rear end of tooth bar 6 forms tooth mouth with the lower end of two gears 9 or upper end respectively and coordinates; Tooth bar 7 after being provided with two between back end beam 5 and gear 9, tooth bars 7 are symmetrically distributed in the both sides of girder 1 after two, and after two, the rear end of tooth bars 7 is connected with back end beam 5, two afterwards the front end of tooth bars 7 form tooth mouth with the upper end of two gears 9 or lower end respectively and coordinate.
The second structure, gear, rack gear are: motor reducer 8 is single shaft reducing motor, and the rotating shaft mouth of motor reducer 8 is provided with gear 9; Be provided with front tooth bar 6 between front beam 4 and gear 9, the front end of front tooth bar 6 is connected with front beam 4, and the rear end of front tooth bar 6 forms tooth mouth with gear 9 lower end or upper end and coordinates; Be provided with rear tooth bar 7 between back end beam 5 and gear 9, the rear end of rear tooth bar 7 is connected with back end beam 5, and the front end of rear tooth bar 7 forms tooth mouth with gear 9 upper end or lower end and coordinates.
When adopting single shaft reducing motor, only having gear 9 outputting power, by the rotation of gear 9, driving front beam 4 and back end beam 5 to do fore and aft motion.It is more reliable and more stable that the motion of monodentate bar is compared in double rack motion.
Just in time contrary during the upper-lower position of front tooth bar 6 and rear tooth bar 7, so just by making gear 9 rotate towards a direction to drive front beam 4 and back end beam 5 to do to stretch out or retract simultaneously.
