The shell 721 of described bedframe 1, first shearing lifting frame 2, second shearing lifting frame 3, first adapter shaft 4, second adapter shaft 5, first crank 9, second crank 10, hollow shaft 71, axle sleeve 73, spring case 72 is the light aluminum alloy materials of quality, the weight of scissors pantograph can be alleviated by actv., be more convenient for the elevating control of scissors pantograph and the loss of energy.
As shown in Figure 5, scissors pantograph is arranged on the roof of electric bus, is wherein provided with insulating part between pantograph and bus roof, usually adopts porcelain insulator, (not marking in figure).When electric bus electric power is finished, electric bus is rested in the charging pile 11 times of battery-charging station, described charging pile 11 is provided with bus duct 12, and charging cable passes from support body, one end of charging cable connects battery charger, does not mark in other end connection bus duct 12(figure).As shown in Figure 2, now open the master cock of cylinder, the external part of cylinder is stretched out from cylinder, the second crank 10, first crank 9 is driven to rotate, the second adapter shaft 5, first adapter shaft 4 is driven to rise respectively, and then drive the first shearing lifting frame 2, second shearing lifting frame 3 rise, crossbeam 6 also follow with powered bow 7 together with rise, finally complete rising bow process.
The road surface of bus stop, because draining needs, can present when designing the arc road surface that centre is high, both sides are low.Such Public Transit Bus Stopping there will be the phenomenon of inclination after platform, adds four pressure of tire differences of bus, more exacerbates the inclination degree of car body.The pantograph being contained in roof rises rear carbon slipper 77 meeting and horizontal surface injustice, have a strong impact on the contact between bus duct 12 on carbon slipper 77 and charging pile 11, contact is caused to have gap, area of contact reduces, thus there is contact surface electric discharge, phenomenon of arc discharge, have a strong impact on charging work, and time length can cause carbon slipper 77 ablation consequence.
For this situation, spring case 72 mechanism that powered bow 7 installs additional can regulate carbon slipper 77 by actv..When carbon slipper 77 horizontal direction not at ordinary times, the application force that the carbon slipper 77 that relative level height is high is applied to bus duct 12 is large, such counteraction is also large at the application force of carbon slipper 77, the amount of compression that carbon slipper 77 compresses Compress Spring 722 by pivot shaft 723 is also large, make the corresponding drop-out value of carbon slipper 77 large, carbon slipper 77 drop-out value that same reason relative level height is low is little, thus ensure that carbon slipper 77 and bus duct 12 can be good at flat contact, wherein in the middle of the process regulated, spring case 72 can rotate around feathering axis 75, realize better contacting between carbon slipper 77 with bus duct 12.In a word, pantograph can be regulated carbon slipper 77 by " adaptive system ", ensures the contact between carbon slipper 77 and bus duct 12, thus adapt to different condition of road surfaces and car body operating mode with this.
As shown in Figure 3, when the carbon slipper 77 on powered bow 7 contacts good with the bus duct 12 on charging pile 11, bus starts to charge.After charging terminates, by the master cock of shifter cylinder, the external part of cylinder is retracted from cylinder, drive the second crank 10, first crank 9 to rotate, drive the second adapter shaft 5, first adapter shaft 4 to decline respectively, and then drive the first shearing lifting frame 2, second shearing lifting frame 3 to decline, crossbeam 6 declines together with also following with powered bow 7, finally complete and fall bow process, the carbon slipper 77 on powered bow 7 is separated with the bus duct 11 on charging pile 10, and electric bus sails out of battery-charging station.
More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed utility model.The claimed scope of the utility model is defined by appending claims and equivalent.
