The specific embodiment
Accompanying drawing discloses the structural representation of a preferred embodiment involved in the present invention without limitation, explains technical scheme of the present invention below with reference to accompanying drawing.
As shown in Figures 1 to 4, a kind of gantry type lift car comprises vehicle chassis 1, gantry type lifting mechanism 2, electric pushrod 3, chain drive 4 and working bucket 5; Described vehicle chassis 1 is equipped with drive wheel 12 and flower wheel 11, and vehicle mobile is driven by drive wheel 12; Described gantry type lifting mechanism 2 comprises outer mast 21, middle part door frame 22, inner upright mounting 23, platform erecting frame 24, and middle part door frame internal upper part is equipped with push rod connecting arm 25, and the gantry type lifting mechanism is driven by chain drive 4 by electric pushrod 3; Described chain drive 4 comprises chain permanent seat I41, draws high chain 42, chain permanent seat II43 and sprocket assemblies 44, chain permanent seat I41 is arranged on outer mast 21, chain permanent seat II43 is arranged on middle part door frame 22, inner upright mounting 23, platform erecting frame 24, and the two ends of drawing high chain 42 are installed on chain permanent seat I41 or chain permanent seat II43; The engine installation of described gantry type lifting mechanism is electric pushrod 3.
Described electric pushrod 3 comprises power end 31 and actuating station 32, and power end 31 floor installations are on vehicle chassis 1, and actuating station 32 tops and push rod connecting arm 25 are movably hinged.
Described electric pushrod 3 is arranged on gantry type lifting mechanism 2 inside.
Gantry type lift car working process is such: the lifting of working bucket 5 is to provide power by electric pushrod 3, electric pushrod 3 comprises motor, retarder, base and actuating station, after electrical power, realize slowing down to increase turning round by retarder, make the leading screw rotation of base inside, realize stretching thereby promote the outside or inside motion of actuating station.due to power end 31 floor installations of electric pushrod 3 on vehicle chassis 1, actuating station 32 tops and push rod connecting arm 25 are movably hinged, push rod connecting arm 25 is arranged on middle part door frame 22 internal upper parts, along with stretching out of electric pushrod 3 actuating stations 32, at first middle part door frame 22 is subject to thrust and rises, the sprocket assemblies 44 at door frame 22 tops, middle part also rises simultaneously simultaneously, be arranged on and draw high chain 42 because the bottom is fixed on outer mast 21 and can't moves by chain permanent seat I41 on sprocket assemblies 44, thereby make install draw high chain 42 other end chain permanent seat II43 inner upright mounting 23 under the promotion of sprocket assemblies 44 to rising, sprocket assemblies 44 on inner upright mounting 23 is also together to rising simultaneously, be arranged on drawing high chain 42 and can't move on door frame 22 because the bottom is fixed on the middle part by chain permanent seat II43 on sprocket assemblies 44, thereby make install draw high chain 42 other end chain permanent seat II43 platform erecting frame 24 under the promotion of sprocket assemblies 44 to rising, working bucket 5 is arranged on platform erecting frame 24 outsides and rises with platform erecting frame 24, the speed that working bucket 5 rises is 3 times of electric pushrod 3 speed, realize the fast rise of working bucket 5, the decline process is the inverse motion process of uphill process.For the higher gantry type lift car of podium level, can realize by the quantity of selecting large stroke, high-performance electric pushrod 3 or increasing the middle part door frame, when using in order to improve vehicle, the stability of working bucket 5, also can install a plurality of gantry type lifting mechanisms; Select large stroke, high-performance electric pushrod 3 also can increase the working load of working bucket 5 simultaneously.
