Technical field
The utility model relates to a kind of four cylinder symmetries and drives heavily cutting fork lifting table, belongs to the mechanical designing technique field.
Technical background
The scissors fork elevating platform of present widespread use mostly is double hydraulic cylinder, and when load was big, needing increased the hydraulic actuating cylinder cylinder diameter, and the change of the shearing force of hinge axis is big, thereby cost is increased, and taking up room becomes big, reliability and life-span reduction.
Summary of the invention
The utility model is intended to solve the shortcoming of above-mentioned prior art, provides a kind of four oil cylinders symmetry to drive heavily loaded scissors fork elevating platform, when load is heavy duty, make the oil cylinder cylinder diameter less, and make the shearing force of hinge axis less, thereby save cost, taking up room diminishes, and improves reliability and life-span.
For solving the problems of the technologies described above, the utility model is achieved in that and comprises the shearing lifting mechanism, base 1 and lifting table 4, base 1 is connected by shearing lifting mechanism with lifting table 4, shear lifting mechanism and comprise interior yoke 5, outer yoke 2 and hydraulic actuating cylinder 3, interior yoke 5 is connected with the mid point hinge of outer yoke 2, one end of interior yoke 5 is connected with lifting table 4 fixed hinges, the other end and base 1 are connected by roller track, one end of outer yoke 2 and lifting table 4 are connected by roller track, the other end is connected with base 1 fixed hinge, and hydraulic actuating cylinder 3 is connected through the hinge with interior yoke 5 and outer yoke 2; Shearing lifting mechanism is two groups that are parallel to each other, shear lifting mechanism for every group and comprise two hydraulic actuating cylinders 3, the piston rod top of each hydraulic actuating cylinder 3 is connected with interior yoke 5 or outer yoke 2 usefulness ball socketed bearings, an other end is connected with the end points hinge of outer yoke 2 or interior yoke 5.
Described four hydraulic actuating cylinders 3 are symmetrically distributed when mounted, and four hydraulic actuating cylinders 3 are identical with horizontal angle.
Described four hydraulic actuating cylinders 3 adopt the control of synchronous valve hydraulic synchronous system, guarantee the synchronism of four hydraulic actuating cylinders 3.
Connect with the hinge real axis between yoke 5 and the outer yoke 2 in described, install support plate additional between two interior yokes 2 of two groups of shearing lifting mechanisms, to satisfy the requirement of transfer motion power.
During use, adopt four hydraulic actuating cylinder synchronized movement of synchronous valve hydraulic synchronous system control, when 4 hydraulic actuating cylinders stretch simultaneously, by hinge connected interior yoke 6 and outer yoke 3 one ends are rotated around fixed hinge, the roller that one end is installed rotates in orbit, thereby makes lifting table 4 rise and fall.
Use the utility model under the certain situation of load, greatly reduce the shearing force of hinge axis, the thrust of the single cylinder that reduces, thus saved cost, reduced to take up room, improved reliability and life-span.
The beneficial effects of the utility model are: under the certain situation of load, single cylinder thrust diminishes; Reduce the shearing force of hinge axis, improved performance and the service life of hinge axis greatly.The utility model load carrying ability is big, it is little to take up room, in-use performance good, rising or falling speed is very fast.
