Cement well pipe equipment manufacturers: control forms and various control methods of bridge cranes

In the operation of the bridge crane, its control system plays a vital role. In addition to the more common control modes of cam controller control and master controller control, the bridge crane also successfully realizes automatic control. , thus improving the sex of each action.

The automatic control system of the bridge crane includes automatic control of the programmable controller, automatic positioning device control, rectification and electrical synchronization of the vehicle running mechanism, electromagnet and its control circuit, and ground control.

The operation of each mechanism of the bridge crane is realized by the program control device; and its automatic positioning generally determines the mechanism form of the device according to the use environment and accuracy requirements of the controlled object, and the automatic positioning device usually uses various detecting elements and Relays, contactors or programmable controllers work together to achieve automatic positioning.

The rectification and electrical synchronization of the running mechanism of the overhead crane in the bridge crane are divided into artificial rectification and automatic rectification. When the rectification exceeds a certain value, the rectification signal generator sends a signal, and the driver disconnects the motor on the side of the leading leg. The motor with the lag leg is adjusted. The automatic correcting deviation is when the skew exceeds a certain value, the correcting command generator issues an instruction, and the system performs automatic correcting. Electrical synchronization is achieved in AC drives where electrical shaft systems with equalizing motors are commonly used for electrical synchronization.
