The utility model provides a kind of vertical pillar lift car that is equipped with Motorized lift device in order to satisfy more user's request.
For realizing above technical purpose, the utility model will be taked following technical scheme:
A kind of vertical pillar lift car, comprise vehicle chassis, column type lifting mechanism, chain drive and working bucket, described vehicle chassis is equipped with drive wheel and flower wheel, described column type lifting mechanism comprises column I, column II, column III, column IV, column II internal upper part is equipped with the push rod connecting arm, described chain drive comprises double chain wheel, draws high chain I, single sprocket chain, draw high chain II, and the engine installation of described column type lifting mechanism is electric pushrod.
Further, described electric pushrod comprises power end and actuating station, and power end base and vehicle chassis are movably hinged, and actuating station top and push rod connecting arm are movably hinged.
Further, to be installed in column type lifting in-house for described electric pushrod.
According to above technical scheme, can realize following beneficial effect:
The utility model is take electric pushrod as lifting power plant, avoided using leakage that hydraulic efficiency pressure system produces on the impact of complete machine and environment, thereby further expanded the field of application of vertical pillar lift car; Use the electric pushrod jacking system, the hydraulic ram, HM Hydraulic Motor, all kinds of hydraulic valve, oil pipe and the joint that are equipped with in the hydraulic efficiency pressure system need not be installed, only need the control power supply of junction circuit system to get final product, simplified greatly product structure, reduced dead weight of vehicle, save the energy, reduce cost, simultaneously also convenient maintenance and maintenance; Electric pushrod has auto-lock function, and actuating station is rested on the position of regulation; Electric pushrod can carry out stepless stroke adjustment according to customer requirements in specified stroke range, thereby implementation platform arrives the purpose of differing heights.

The specific embodiment
Accompanying drawing discloses the structural representation of the related preferred embodiment of the utility model without limitation, explains the technical solution of the utility model below with reference to accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of vertical pillar lift car comprises vehicle chassis 1, column 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 column type lifting mechanism 2 comprises column I21, column II22, column III23, column IV24, and column II internal upper part is equipped with push rod connecting arm 25, and column type lifting mechanism is driven by chain drive 4 by electric pushrod 3; Described chain drive 4 comprise draw high chain I41, single sprocket chain 42, draw high chain II43, double chain wheel 44; The engine installation of described column type lifting mechanism is electric pushrod 3.
Described electric pushrod 3 comprises power end 31 and actuating station 32, and power end 31 bases and vehicle chassis 1 are movably hinged, and actuating station 32 tops and push rod connecting arm 25 are movably hinged.
Described electric pushrod 3 is installed in column type lifting mechanism 2 inside.
Vertical pillar 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, behind the electrical power, realize slowing down to increase turning round by retarder, the leading screw of base inside is rotated, realize stretching thereby promote the outside or inside motion of actuating station.Because power end 31 bases and the vehicle chassis 1 of electric pushrod 3 are movably hinged, actuating station 32 tops and push rod connecting arm 25 are movably hinged, push rod connecting arm 25 is installed in column II22 internal upper part, along with stretching out of electric pushrod 3 actuating stations 32, column II22 at first is subject to thrust and rises, the single sprocket chain 42 at column II22 top also rises simultaneously simultaneously, the chain I41 that draws high that is installed on the single sprocket chain 42 is fixed on the column I21 and can't moves owing to the bottom, thereby so that the column III23 that fixedly draws high the chain I41 other end under the promotion of single sprocket chain 42 to rising, double chain wheel 44 on the column III23 is also together to rising simultaneously, the chain II43 that draws high that is installed on the double chain wheel 44 is fixed on the column II22 and can't moves owing to the bottom, thereby so that the column IV24 that fixedly draws high the chain II43 other end under the promotion of double chain wheel 44 to rising, working bucket 5 is installed in column IV24 outside and rises with column IV24, 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 then is the inverse motion process of uphill process.For the higher vertical pillar lift car of podium level, can realize by the quantity of selecting large stroke, high-performance electric pushrod 3 or increase column; Select large stroke, high-performance electric pushrod 3 also can increase the working load of working bucket 5 simultaneously.
Electric pushrod has auto-lock function, and electrical motor stops operating, and push rod rests on certain position immediately, and the height that makes platform remain on setting carries out aloft work; Electric pushrod can according to customer requirements, carry out stepless stroke adjustment in specified stroke range; Electric pushrod adopts integrated full-closed structure, need not safeguard, volume is little, is convenient to installation and maintenance; Electric pushrod adopts gear and lead screw transmission, is active in one's movements, and operates steadily, and Stroke Control is accurate.The existing specialized factory of electric pushrod produces, and can directly buy needed model and specification.
Obviously, above-described embodiment only is for example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being extended out thus or change still are among the protection domain of the utility model creation.
