Description
Technical field
The utility model relates to a kind of electric hydaulic lifting machine, especially a kind of mobile type electric hydraulic lifting machine.
Background technology
In the vehicle maintenance and repair field, electric hydaulic lifting machine commonly used is that lifting machine main body is installed on the movable trolleys, conveniently moving, the different places of can applying in a flexible way.Dolly comprises carriage and wheel, and carriage is overhead nearer, and wheel can not freely rise and fall, and when meeting uneven dirt road, inconvenient walking, and when lifting machine jack-up workpiece, wheel is subjected to very big antagonistic force very easily causes the wheel damage.Moreover the ram cylinder of common lifting machine can only stretch out a joint, and stroke is little, is not suitable for keeping in repair full-sized car.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, and provide a kind of easy to use, alleviate wheel and damage, and be applicable to the mobile type electric hydraulic lifting machine of all size vehicle workpiece maintenance.
The utility model is to realize like this, mobile type electric hydraulic lifting machine comprises carriage, wheel, hydraulic cylinder assembly, pumping plant assembly, described wheel flexibly connects by spider and carriage, wheel is made up of two front-wheels and a trailing wheel, described front-wheel is positioned at the corner point of spider, and angle point links to each other with described carriage by rotating shaft behind of spider, another back angle point of spider is connected with curved arm rod, described curved arm rod is not held and is connected with the carriage hydraulic cylinder assembly, carriage oil cylinder cylinder bar lower end links to each other with described trailing wheel, and described carriage hydraulic cylinder assembly is provided with operating handle.
As a kind of improvement of the present utility model: described hydraulic cylinder assembly comprises base, oil cylinder overcoat, piston cylinder bar, pressuring oil pipe, rising oil pipe down, is provided with plunger tpe cylinder bar in the described piston cylinder bar.
The utility model mobile type electric hydraulic lifting machine as power, utilizes high pressure oil output with electric hydaulic, and driving oil cylinder is done the lifting campaign, thereby the vehicle workpiece of required processing is lifted; The small oil tank of carriage hydraulic cylinder assembly stretched out when this mobile type electric hydraulic lifting machine was pulled handle, promote front-wheel and trailing wheel by curved arm rod, make base bracket be raised to the correct position that convenient walking is moved, after the lifting machine moves to the work place, loosening handle makes the base bracket whereabouts and contacts wheel rise built on stilts with ground, select suitable working head, insert cylinder bore, the correct position of alignment pieces starts power supply, make hydraulic power unit work, working head lifts workpiece, when raising once more as the need working head, handles the change-over valve handle, thereby making hydraulic oil enter oil cylinder promotion piston cylinder by oil pipe contacts with the outer set upper side of oil cylinder, continue pressurization, the lever of plunger case begins to rise, when the plunger lever contacts with the piston cylinder lever, by pass valve begins oil return, and handling change-over valve can stop or falling after rise.But because the utility model wheel regulated at will height, cause base bracket can be raised to the correct position that convenient walking is moved, and this lifting machine does when lifting action, carriage contacts with ground, wheel rises built on stilts, so wheel of the present utility model is not fragile and the walking convenient.Owing to be provided with plunger tpe cylinder bar in the piston cylinder bar of the present utility model, stroke is long again, can satisfy the maintenance of all size vehicle workpiece.
