Description
Technical field
Cargo handling equipment technical field is the utility model is related to, more particularly to field bridge cart jacking cylinder with mechanically
Catching device.
Background technology
Harbour tyred container door type crane (calling a bridge in the following text) is because lifting capacity is big, itself weight is also big, to ensure a bridge
It is timely to cross the street transition steering situation (0 ° goes to 90 ° or 90 ° and goes to 0 °) response, reduction cart tire steering frictional resistance, every
Bridge, which is respectively provided with, is provided with hydraulic power unit and four jacking cylinders, transfers, and four jacking cylinders are placed in field by diagonal
Below portal frame saddle beam and four door leg connecting portions.When bridge needs the transition to turn to, driver manipulates cart pole changer in drivers' cab,
Hydraulic power pumping plant presses program, there is provided pressure oil is sent to jacking cylinder rodless cavity, and jacking piston rod downlink is until by whole field bridge
Jack up, after 8 cart tires completely disengage ground, the action of steering cylinder piston rod, promotes cart tire without any resistance feelings
Under condition, tire is gone to 90 ° or 90 ° from 0 ° and goes to 0 °.After the completion of steering, steering cylinder stops, and pressure oil is sent to jacking cylinder
Rod chamber, jacks piston rod uplink, and 8 tires transfer to ground, complete steering procedure, avoids tire friction and complicated bent torsion damage
Wound, extends the service life of tire.During the bridge normal operation of field, to make the piston rod of vertically arranged jacking cylinder and connection ball seat

Have characteristic and caused by system high pressure oil slowly leak, to ensure that piston rod and ball seat will not drop in operation.
After field bridge oil changes electricity, it is contemplated that input cost, the inverter capacity of selection is smaller, when field bridge is with alternating current operation, just
It cannot power to hydraulic jacking system, high pressure oil slowly leaks in hydraulic system, and pressure cannot compensate in time, and piston rod
And the combined influence such as ball seat dead weight, piston rod glides with ball seat, fall failure often occurs.For the above-mentioned downslide of solution, event of falling
Barrier, magnetic cylinder is installed using in jacking cylinder piston rod head.After the contraction of piston rod uplink is jacked in place, magnetic cylinder absorption jacking oil
Cylinder barrel end cap, compensation hydraulic is substituted with magnetic cylinder magnetic-adsorption, prevents piston rod and ball seat from dropping.
Elapsed with usage time, the anti-fall deficiency of magnetic force also progressively shows, and adsorption capacity declines, and magnetic cylinder is easily rupturable, buying
Monovalent high, reliability is low, and downslide, fall failure are more, and the ball seat to fall and the accident of field bridge runway scraping collision also happen occasionally.For
This, can only frequent starting field bridge diesel generating set to hydraulic power station power, using hydraulic system compensate pressure, pack up jacking
After piston rod, stop generating set again, switch back into alternating current operation.This measure not only time-consuming excessive fuel consumption, influences operating efficiency, also increases
Repair personnel's work on duty.
