Technical field:
The utility model relates to the construction implement field, is specifically related to the revolution vortex flow control device that impacts when a kind of may command tower machine turns round.
Background technology:
In the rotating actual motion of tower machine, exist a difficult problem: because the tower horn is long always, slew gear has bigger inertia, tower machine fuselage rocks greatly during parking, particularly when stopping suddenly by top gear, tower machine fuselage rocks quite severely, has bigger impact, can cause damage to the tower machine.
The utility model content:
Big the rocking of fuselage when revolution is stopped of tower machine avoided in greater impact when technical problem to be solved in the utility model is how tempering tower machine revolution.
Technical problem of the present utility model is to solve by following technical scheme.It comprises the eddy-current brake that is loaded on the turning motor, it is characterized in that eddy-current brake and voltage regulating module link, this voltage regulating module links with transformer and printed circuit board again simultaneously, transformer connects power supply processing circuit, printed circuit board is provided with two or more potentiometers, connect transformer and Programmable Logic Controller simultaneously, and connect signal processing circuit.
The utility model can be according to the rotating speed stage of difference, applies different dc voltage values for the eddy-current brake of turning motor, thereby applies different eddy current braking amounts for different revolution gears, with the impact of buffering revolution when the gear shift.It adopts voltage regulating module and Programmable Logic Controller and homemade printed circuit board, the voltage of the eddy-current brake of turning motor is carried out phase shift to be regulated, solve the tower machine in good condition and in running, turned round the startup difficulty, start-up time is long, the tower machine rocked bigger when revolution was stopped, after work a period of time, the difficult problem that the turning motor heating is serious.
Description of drawings:
Fig. 1 is the utility model circuit diagram;
Fig. 2 is the utility model printed circuit board figure.
Embodiment:
As shown in Figure 1, it comprises eddy-current brake YBSE1, the YBSE2 that is loaded on the turning motor, it is characterized in that described eddy-current brake YBSE1 is connected a voltage regulating module UC with YBSE2, this voltage regulating module UC can carry out phase shift to be regulated the voltage of eddy-current brake YBSE1, the YBSE2 of turning motor, eddy current braking amount with the control turning motor, it links with printed circuit board SCC again simultaneously, and printed circuit board SCC connects Programmable Logic Controller PLC simultaneously.As shown in Figure 2, printed circuit board SCC is provided with two or more potentiometers R, and PLC links with the Programmable Logic Controller output point, and connects signal processing circuit.
The utility model is provided with two transformer: T1, TE.T1 connects power supply processing circuit, and SCC provides power supply for printed circuit board, and TE provides power supply for eddy-current brake YBSE1, YBSE2 and other element of motor.The voltage that eddy-current brake YBSE1, YBSE2 are applied in is the alternating current of 24V before phase-shift voltage regulating.When turning round one grade, the output point Y54 closure of Programmable Logic Controller PLC, the printed board major loop gets electric, and through the fixed voltage value between 0～5V of output behind the scale operation, this magnitude of voltage also can be adjusted by regulation voltage device R1; Y53 closure during second gear can be adjusted by regulation voltage device R2; Y52 closure during third gear can be adjusted by regulation voltage device R3; Y51 closure during fourth gear can be adjusted by regulation voltage device R4; Y50 closure in the time of five grades, this moment, output voltage was 0V.This output valve is as the control voltage of voltage regulating module UC, the function of voltage regulating module UC is the size according to control voltage (as 318 output voltage among Fig. 2), output produces the broad pulse of mobile phase in the scope from 180 ° to 0 ° with the synchronous double electric voltage frequency of line voltage, in order to driving stochastic pattern SSR, thereby reach the purpose of phase-shift voltage regulating.Corresponding so rotating different gears, vortex controller YBSE1 just can export different magnitudes of voltage, thereby make turning motor when different speed stage operations, be applied in different magnitudes of voltage, the impact of buffering turning motor when gear shift on its eddy-current brake YBSE2.
Direct voltage on the eddy current braking circuit board between 607,608 two terminals, the operating voltage of eddy-current brake YBSE1, YBSE2 just, it has determined the moment of eddy current braking, and the voltage height is then braked great efforts, and voltage is low, and then braking moment is little.The utility model is debugged when dispatching from the factory, when running into following situation in the middle of reality is used, can also adjust the output valve of revolution eddy-current brake YBSE1.
The adjustment of eddy current voltage value is to finish by the potentiometer R that regulates in the printed board.We can be clear that five potentiometer R1, R2, R3, R4, R5 in printed board, clockwise regulator potentiometer, and then the eddy current voltage value raises, and braking puts more effort, counterclockwise regulator potentiometer, then the eddy current voltage value reduces, and the braking dynamics reduces.At every grade be adjusted to: regulate R4 for one grade, these shelves are in handle plate input during to one grade of revolution; Second gear is regulated R3, and these shelves drop into when turning round second gear in handle plate; Third gear is regulated R2, and these shelves drop into when turning round third gear in handle plate; Fourth gear is regulated R1, and these shelves drop into when turning round fourth gear in handle plate; Five grades are dropped into five grades the time to revolution at handle wrench, need not regulate.
Transfer not get on if find certain gear voltage in the adjustment process, at this moment can change its multiplication factor by regulator potentiometer R5, and then regulate the potentiometer of this gear correspondence.This grade adjusting finishes, and other gear then must be transferred under the situation that the R5 value remains unchanged again.
At the scene in the debug process, make corresponding adjustment after analyzing as the case may be: general in conjunction with the current value of observing digital operator on the frequency converter, when each shelves operation, current value is not greater than the twice of motor rated current (bi-motor is in two electric current sums).As when finding that revolution starts difficulty, start-up time is when long, and after getting rid of mechanical possible breakdown, regulator potentiometer R4 is till its eddy current voltage value turned down fault and eliminate; If after finding work a period of time, the turning motor heating is serious, and may be that eddy current voltage is higher causes, suitable regulator potentiometer R1, even R2, R3, R4 are till satisfaction.
