Description
One, technical field
The utility model belongs to the elevator machinery Electrical Control Technology, is specifically related to the vortex flow control device of a kind of tower crane rotation mechanism.
Two, background technology
Advantages such as at present, domestic tower machine uses the more and more of variable frequency control, and it is steady that it has speed adjusting performance, and the adjusting speed accuracy height responds soon, and the good mechanical property of electrical motor improves mechanical life, and the electric elements life-span is long, and fault rate is low.But be applied in the revolution because the special operating characteristic of swing type mechanism, quicken with the process of slowing down in, can produce impact owing to inertia to steel structure, this impact has certain infringement to tower machine structure.Swing type mechanism is the most important transmission device of tower crane, use the swing type mechanism of variable frequency control, because good in-use performance is safeguarded with simple, be subjected to user's favor, but the way of general producer is to use closed loop control, so not only cost increases, and maintenance capacity is bigger, needs often to change consumable accessory.
Three, summary of the invention
The purpose of this utility model provides a kind of tower crane rotation mechanism vortex controller, the shock problem when solving the swing type mechanism speed change.
The technical solution adopted in the utility model is: tower crane rotation mechanism vortex controller has a rectification module MK, the anodal signal control end con that inserts rectification module MK of frequency converter output 10～0VDC signal, negative pole meets the ground terminal com of rectification module MK, power input AC1, the AC2 of rectification module MK connects 24VAC, rectification module MK output+,-end connection eddy current coil RRa, rectification module MK+negative electrode of terminating diode Red, rectification module MK-end connects the anode of diode Red.
During work, at first the power input AC1 of rectification module MK and AC2 insert power supply 24VAC, by control signal 10-0VDC the signal control end con of rectification module MK is controlled then, make the mouth of rectification module MK+with-correspondent voltage output (output area: 20VDC～0VDC) arranged.
In the middle of the process that control voltage is changed by 10VDC～0VDC, eddy current voltage is being followed by height and is being changed to low, (by 20VDC～0VDC), cooperate the output of frequency conversion this moment, can reach different speed, realizes that pulsation-free quickens and moderating process.
Add a potential device R1 at the signal input part con of rectification module MK, frequency converter output 10～0VDC signal positive pole inserts the signal control end con of rectification module MK through potential device R1.The effect of potential device R1 is the size of regulating control voltage, to adapt to the tower crane of different brachiums.When control voltage in different size, its eddy current output voltage also becomes thereupon, so just can pass through regulator potentiometer when different brachiums, sets the maxim of output voltage, thereby satisfied controls requirement.
The utility model and frequency converter are used, and can regulate by potential device according to the different brachium of tower crane, satisfy the requirement of different tower machines, to reach perfect controller performance.The utility model is simple in structure, implements easily, and is with low cost, is fit to adopt the tower machine of variable frequency control to use.
Four, description of drawings
Accompanying drawing is schematic circuit diagram of the present utility model.
Five, the specific embodiment
Rectification module MK adopts DQZ-36D190 silicon control bridge-type rectification module; Diode Red selects MZP25A/600V for use; Potential device R1 is 1W/10K Ω; The secondary 24VAC of voltage transformer is connected to power input AC1, the AC2 of rectification module MK; The eddy current coil RRa of motor output end be connected on rectification coil+,-mouth; The frequency conversion output signal of taking from frequency converter inserts the signal input part con of rectification module MK through resistance R 1.
