Description
Technical field
The utility model relates to Electric Chain Blocks, and in particular to the stepless time adjustment controller of Electric Chain Blocks.
Background technique
It is well known that Electric Chain Blocks includes electric block host, it is provided with frequency converter in host control cabinet, will be passed through
The power supply of frequency converter processing exports to the main circuit of electric block the raising and decline for controlling electric block, still, existing
The output frequency of frequency converter cannot change, and cannot also realize stepless time adjustment, can not adjust the lifting velocity of cucurbit.
Summary of the invention
The purpose of this utility model is: designing the stepless time adjustment controller of Electric Chain Blocks, changes the output of frequency converter
Frequency realizes stepless time adjustment, so as to adjust the lifting velocity of cucurbit.
The technical solution of the utility model is: the stepless time adjustment controller of the Electric Chain Blocks is in electric block
Main circuit on connect main circuit of frequency converter, main circuit of frequency converter includes rectifier and braking resistor, frequency converter R, S, T terminal
Main power source is connect, frequency converter U, V, W connect electric block major loop motor lines, and frequency converter B 1, B2 terminal connect braking resistor, frequency converter
RA, RC terminal connect rectification circuit, and frequency converter COM, X1, X2 terminal connects control handle, and frequency converter+10V, A11, GND terminal connect
Stepless time adjustment spin button.
The utility model has the advantages that: circuit is simple, novel in design, and the promotion speed of electric block arbitrarily adjusts the speed, and realizes
It is accurately positioned and fast lifting, improves working efficiency, it is possible to use on the lifting equipment of other similar functions, practical performance
It is excellent, it is very promising for marketing..
Detailed description of the invention
Fig. 1 is the circuit diagram of the utility model.
Specific embodiment
Technical solutions of the utility model are further illustrated with reference to the accompanying drawing.
As shown in Figure 1, the stepless time adjustment controller of the Electric Chain Blocks is to connect to become on the main circuit of electric block
Frequency device major loop, main circuit of frequency converter include rectifier and braking resistor, and frequency converter R, S, T terminal connects main power source, frequency converter
U, V, W connect electric block major loop motor lines, and frequency converter B 1, B2 terminal connect braking resistor, and frequency converter RA, RC terminal connects rectification
Circuit, frequency converter COM, X1, X2 terminal connect control handle, frequency converter+10V, A11, GND terminal connect stepless time adjustment rotation by
Button.
When work, power on, press the lifting key in control switch, frequency converter work, by the power supply of processing export to
The main circuit of electric block, while RA, RC normally opened contact become normally-closed contact on frequency converter, rectification circuit forms closed loop, brake
It opens, motor rises operation；Disengagement lever switch, frequency converter stop working, and disconnect the main circuit of power supply and electric block, simultaneously
RA, RC normally-closed contact become normally opened contact on frequency converter, and rectification circuit forms open loop, brake, and motor is out of service；It presses
Down key key in control switch, frequency converter work export the power supply of processing to the main circuit of electric block, while on frequency converter
RA, RC normally opened contact become normally-closed contact, and rectification circuit forms closed loop, and brake is opened, the operation of motor down key；Disengagement lever is opened
It closes, frequency converter stops working, and disconnects the main circuit of power supply and electric block, while RA, RC normally-closed contact become normal on frequency converter
Open contact, rectification circuit forms open loop, brake, and motor is out of service；During running herein, rotation stepless time adjustment is pressed
Button changes frequency converter output frequency, so as to adjust the lifting velocity of cucurbit.
