Abstract
The invention discloses a double-column type hydraulic lifting machine. The double-column type hydraulic lifting machine comprises two symmetric stand columns perpendicular to the ground; two bosses are arranged between the two stand columns in parallel; a connecting line between the two stand columns is perpendicular to the bosses and penetrates the middle points of long edges of the bosses; hydraulic rods installed in hydraulic cylinders below the bosses penetrate the bosses to be connected with supporting rods; the upper surfaces of the two ends of each supporting rod are each connected with an anti-slip device; the hydraulic cylinders are connected with a hydraulic pump through a hydraulic pipe; the hydraulic pump is driven by a motor; and the motor is controlled by a control box installed on any stand column. According to the double-column type hydraulic lifting machine, synchronous work is performed through the two hydraulic cylinders connected in series, it is cancelled that an existing double-column type lifting machine needs a steel rope and a chain for balance, and a series of problems caused by the faults of the chain and the steel rope are fundamentally eradicated; and meanwhile, because the two hydraulic cylinders are connected in series, synchronous lifting can be achieved, and stress is balanced.

The ground space of amount, facilitates Ground Operation.Twin post auto lifting machine is most widely used at present, the one of occupancy maximum
Kind, but automobile falling accident and happens occasionally in existing double-column lifter, and main reason is that there is problems with：Firstth,
Existing double-column lifter typically realizes rising or falling of lift arm using hydraulic driving mode, but in order to realize both sides lifting
The synchronization of arm and stress balance, are generally driven using cable wire and chain, and in long-term friction and drawing process, cable wire holds
It is also easy to produce fatigue fracture or damaged fracture, lead to the generation of security incident.Secondth, automobile can sail lifting work into for convenience
Position, existing lift arm is all arranged to swing arm, is flexibly connected with lifting frame by way of hinged, due to four swing arms it
Between unbalance stress, lead to tilting of automobile even slip lead to automobile to fall and security incident generation.
Content of the invention
It is an object of the invention to provide a kind of queen post hydraulic jack, existing described in background technology for solving
Easily fatigue fracture in the balance drive cable wire that double-column lifter exists, and lifting swing arm leads to be lifted vapour because of unbalance stress
Car tilts the problem of sliding pendant.The present invention adopts brand-new design, eliminates the structure being balanced by cable wire and chain, from root
The occurrence of prevented cable wire fatigue fracture on this, meanwhile, the present invention also eliminates lifting swing arm, solves lifting well
There is the problem of sliding pendant in swing arm unbalance stress.
In order to reach above-mentioned technique effect, the present invention is achieved through the following technical solutions：
A kind of queen post hydraulic jack, including two symmetrical and vertical columns arranging with ground, between described two root posts
It is arranged with two boss in parallel, the line between described two root posts is vertical with described boss and passes through in the long side of described boss
Point, the hydraulic stem being provided with below described boss in hydraulic cylinder is run through described boss and is connected with support bar, described support bar two ends
Upper surface is connected with nonskid device, and described hydraulic cylinder is connected with hydraulic pump by hydraulic tube, and described hydraulic pump passes through motor-driven,
Described motor is controlled by the control box being arranged on any one root post.
Preferably, described support bar is connected with the gimbal lever near the side of described column, and the described gimbal lever other end is in ellipse
Circular and be embedded in column.
Preferably, the top of described two root posts is fixedly connected by stabiliser bar.
Preferably, described boss is mainly made up of with the sloping platform that is connected with described platform two ends the platform positioned at middle part, institute
Tell that platform upper surface is provided with anti-slip veins.
Preferably, the length of described platform is 4 meters, and width is equal with described sloping platform width to be 0.35 meter.
Preferably, described nonskid device includes the rubber bodies on metallic object positioned at bottom and top, described rubber bodies upper surface
It is provided with a plurality of irregular grain groove.
The present invention compared with prior art, has advantages below and beneficial effect：
（1）The present invention is worked by the hydraulic cylinder of two series connection simultaneously, and eliminating existing double-column lifter needs to adopt
What cable wire and chain were balanced is related to, and has fundamentally prevented to occur because of the series of problems that chain and cable wire fault lead to,
Simultaneously as two hydraulic cylinder series connection, it is capable of lifting, stress equalization simultaneously.
（2）The present invention is due to employing fixed support bar, and is directly fixedly connected with the hydraulic stem of lower end, this support
Even if bar is also not in inclination in the case of the volume of unbalance stress, both ensure that the reliability of connection, and also solved and lifted
The problem of Anti-inclining and sliding pendant in journey.
（3）Support bar is also connected with the gimbal lever being embedded in column, in the case of unbalance stress, increases steady
Qualitative, reduce the lateral stressed of hydraulic stem, effectively extend the service life of hydraulic stem.
