Drawings
FIG. 1 is a block diagram of a tower hoist electrical control system;
wherein, 1-a main power supply circuit; 2-a frequency converter; 3-a brake; 4-overload detection sensor; 5-operating the control box; 6-cumulative timer.
Detailed Description
The following detailed description of the embodiments of the present invention is provided in connection with the accompanying drawings and the embodiments. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1, the tower crane electrical control system includes a main power supply circuit 1, a frequency converter 2, a brake 3, an overload detection sensor 4, an operation control box 5, and an accumulation timer 6.
When the tower crane electric control system is used, firstly, the main power supply circuit 1 provides an equipment power supply, the frequency converter 2 is powered on, and the whole system finishes power supply. After power supply, the parameters of the frequency converter 2 are set (set only for the first use) and stored. After the parameter setting is finished, the equipment can be operated, and the power supply of the brake 3 is electrified after the frequency converter is operated. If overload occurs in the overload detection sensor 4 during operation, the overload detection sensor will give an alarm, and the alarm is arranged on the operation control box 5 and can give continuous audible prompt. The running time is recorded by the running accumulation timer 6. The operation control box 5 can be operated in the car to realize manual control, and can be operated outside the car to realize automatic control.
The above examples are only preferred embodiments of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
