A kind of parallel―ordinal shift handling device
The invention belongs to a kind of handling facilities of logistics field, one kind parallel four of the handling especially between high-low-position connects
Bar handling device is also applied on automatic packaging production line as transloading equipment, to improve production work efficiency.
General logistics scene needs the transshipment cargo between plateau and ground, to realize this function, for large-scale whole
The handling of cargo（Such as the large-scale parts in project building site）Mostly using portal frame handling device, and self-contained medium-sized logistics（Such as collection
Vanning, diesel bucket, clamp plate type stacking target）Scissors lifting platform, crane or fork truck can be used, but for small logistics in bulk type
（Such as net purchase object, agricultural product）And for the logistics on factory automation production line, portal frame, scissors lifting platform, crane
With fork truck because of its huge structure, large-tonnage, floor space is larger, the speed of service is slow, theirs are influenced on space and structure
Transfer efficiency, the shipping and delivery cost for making every tonnage are higher.Especially indoors or small-sized, quick and high-frequency handling occasion, gantry
Frame, crane and fork truck just lose their advantage.Alternatively possible solution more flexible, that efficiency is higher is using hand
Dynamic, hydraulic pressure or motor-driven double leval jib handling facilities, such as the one kind mentioned in Chinese patent CN202011726U is with liquid
Pressure oil is the double leval jib handling facilities of direct driving force.But all imply using energy source in well known double leval jib handling facilities
The problem of rate is not high, i.e., with the driving that the variation of connecting rod swing angle causes the amplitude of variation of torque too big, practically necessary
Power is also with periodically fluctuating widely, so needing to match power of motor according to maximum moment standard（Or the electricity of hydraulic pump
Acc power）, in fact, motor only at a time just can full load operation, as long as the average torque needed for whole process is most
The 64% of high-torque, so result in motor in itself at least 36% power（The energy）Waste, be unfavorable for energy-saving and emission-reduction.
As automated production workshop is increasing and the rise of net purchase industry, corresponding modern logistics industry is also sent out increasingly
It reaching, middle-size and small-size loose mail logistics will occupy the exhausted large scale of social logistics total amount, horizontal in order to improve the efficiency of loading and unloading and handling civilization,
The trend of social handling facilities will be become using the double leval jib construct for handling of maneuverability.
Energy-saving and emission-reduction demand based on the whole society, it is necessary to which changing in structure is carried out to well known double leval jib charging crane
Into to obtain better energy-saving and emission-reduction benefit.
