Accompanying drawing explanation
Fig. 1 is the circuit structure diagram that piler energy conversion device that the embodiment of the present invention provides is applied to piler.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, illustrate only part related to the present invention in accompanying drawing but not full content, unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present invention understand usually.The object of term used in the description of the invention herein just in order to describe specific embodiment, is not intended to be restriction the present invention.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
As shown in Figure 1, in the present embodiment piler energy conversion device piler electrical network and horizontal drive frequency converter and hoist to drive between frequency converter an energy conversion module MDR1 be set.Piler electric control part is divided and is comprised horizontal drive frequency converter U1, hoist drive frequency converter U2, pallet fork drive frequency converter U3, the horizontal drive motor M1 be connected with horizontal drive frequency converter U1, with the drive motor M2 that hoists driving frequency converter U2 to be connected that hoists, the pallet fork drive motor M3 driving frequency converter U3 to be connected with pallet fork.It should be noted that, described energy conversion module MDR1 can adopt model to be any one of MDR60A or MDR61B renewable power supply.Described horizontal drive frequency converter U1 and hoisting drives frequency converter U2 that model can be selected to be any one of MDX60B or MDX61B frequency converter.
Energy conversion module MDR1 adopts model to be the renewable power supply of MDR60A0150 in the present embodiment, horizontal drive frequency converter U1 adopts model to be the frequency converter of MDX61B0055-5A3-4-0T, hoists and drives frequency converter U2 to adopt model to be the frequency converter of MDX61B0150-503-4-0T.Main circuit power terminal L1, L2, L3 of energy conversion module MDR1 are connected with electrical network L1, L2, L3 tri-through reactor ND1, filter NF1, circuit breaker Q 1; + the UZ ,-UZ of first group of lead-out terminal of energy conversion module MDR1 are connected with terminal+the UZ ,-UZ of horizontal drive frequency converter U1; + the UZ ,-UZ of second group of lead-out terminal of energy conversion module MDR1 are connected with terminal+the UZ ,-UZ driving frequency converter U2 that hoist.
During normal operation, in piler horizontal movement situation, it needs to carry out braking before arriving picking point and does retarded motion, now, because effect of inertia will produce a large amount of potential energy, to be electric energy feedback by potential energy converting and energy to hoisting drive frequency converter U2 to energy conversion module MDR1 or feed back to electrical network resupplies pallet fork and drive frequency converter U3, drives the drive motor M2 and pallet fork drive motor M3 that hoists to work.In like manner, in stacker loading platforms decline situation, also a large amount of potential energy can be produced, potential energy converting and energy is electric energy feedback to horizontal drive frequency converter U1 or feeds back to electrical network and resupply pallet fork and drive frequency converter U3 by energy conversion module MDR1, drives horizontal drive motor M1 and pallet fork drive motor M3 to work.
