Description
Technical field
The present invention relates to a kind of lifting table, relate in particular to hydraulically-driven lifting platform.
Background technology
Lifting table be used in widely building, power department etc. need ascend a height install, the field of upkeep operation.Present three cylinder hydraulic elevating platforms are a kind of big operation table tops that have, and higher operation height and anti-load capacity are strong, the lifting table that stability is high.As Fig. 1, Fig. 2, three cylinder hydraulic elevating platforms comprise three telescoping cylinders 1, polylith synchronous plate 2 and control mechanism 3, synchronous plate 2 is generally circular slab, and three telescoping cylinders 1 and each piece synchronous plate 2 direct connection are together, 1 oil-feed simultaneously of three telescoping cylinders of control mechanism 3 controls, make their synchronous risings, synchronous plate 2 arrives setting height along with oil cylinder 1 rises together up to lifting table.
Though the problem that three cylinder hydraulic elevating platforms exist is to have synchronous plate 2 to guarantee that oil cylinder 1 makes progress synchronously, but also can't avoid not exclusively synchronous problem of three oil cylinders, 1 rising fully, in case synchronous plate motion overbalance, lifting table is easy to generate stuck situation, because the height of lifting table is very high, stuck back service work is wasted time and energy, and has a strong impact on job schedule.
Summary of the invention
The object of the present invention is to provide better synchronous hydraulic lifting platform of a kind of synchronism, stability, can avoid the generation of the stuck situation of lifting table.
The present invention is achieved in that a kind of synchronous hydraulic lifting platform, comprise telescoping cylinder, polylith synchronous plate and control mechanism, it is characterized in that, every synchronous plate below all is set with four angle steel, and the position of every block of synchronous plate below angle steel is all different with other synchronous plates in vertical direction, and every synchronous plate also is provided with a plurality of through holes;
Every angle steel bottom all is set with a chain pipe link;
Every synchronous plate lower surface all is set with 16 sprocket wheels, and per four sprocket wheels are near same angle steel, and these two pairs of sprocket wheels direction that meets at right angles lays respectively at the angle steel both sides;
Every synchronous plate also is provided with eight chains, every chain upper end is fixedly connected on an angle steel upper end, chain is walked around a near sprocket wheel of this root angle steel downwards along this root angle steel, walking around near the sprocket wheel of another root angle steel of next door again, captives joint with this chain pipe link with the angle steel lower end in the chain lower end.
Clear size of opening on the described synchronous plate can make angle steel pass, and the number of openings on every synchronous plate equals this all angle steel quantity sums of piece synchronous plate top.
Described lifting table is provided with four telescoping cylinders.
Described every chain on two sprocket wheels around on the contrary.
Balance when the present invention utilizes chain pipe link, chain, sprocket wheel and angle steel to guarantee the synchronous plate motion, keep stable when making the synchronous plate motion, significantly reduced the oil cylinder motion not exclusively synchronously or the lifting table stuck situation that causes of reasons such as friction drag, and it is simple in structure, used unit need not special processing, and cost is not high.Synchronous hydraulic lifting platform of the present invention is specially adapted to heavy constructions such as power construction.
