遼寧橋式起重機的控制

Bridge crane control

一、遼寧橋式起重機控制形式

Crane control form

1、凸輪控制器控制

1, cam controller

2、主令控制器控制

2, the main control of the controller

二、自動控制

Two, automatic control

1、可編程序控制器自動控制。起重機各機構的運行要依靠程序控制裝置來實現,現在起重機多使用可程序控制器來控制。

1, programmable controller automatic control. Crane operation of the various agencies to rely on the program control device to achieve, and now more than the use of a crane to control the programmable controller.

2、自動定位裝置控制。起重機的自動定位,一般是根據被控對象的使用環境、精度要求來確定裝置的機構形式,自動定位裝置通常使用各種檢測元件與繼電器、接觸器或可編程序控制器相互配合,以達到自動定位的目的。

2, automatic positioning device control. Automatic positioning of the crane, the general is to determine the form mechanism according to the requirements of the controlled object environment, precision automatic positioning device usually use various detection devices and relays, contactors or PLC with each other, in order to achieve the purpose of automatic positioning.

3、地面操做、有線與無線遙控葫蘆式起重機采用地面控制,其關鍵部件是手動按鈕開關。有線遙控是通過專用電纜或動力線作為載波體,對信號用調制解調器傳輸方式,達到只用少量通道即可實現控制的方法。

3, ground operation, wired and wireless remote control hoist crane using ground control, the key part of the manual button switch. Wired remote control is a dedicated cable or power line as a carrier, the signal with modem transmission mode, to achieve a small number of channels can be used to control the method.

無線遙控利用當代電子技術,將信息以電波或光波為通道形式傳輸,達到控制的目的。

Wireless remote control by the use of modern electronic technology, information will be transmitted in the form of radio waves or light waves, to achieve the purpose of control.

4、大車運行機構的糾偏和電氣同步。糾偏分為人為糾偏和自動糾偏,人為糾偏是當糾偏超過一定值后,糾偏信號發生器發出信號,司機斷開超前支腿側的電動機,接通滯后支腿偏的電動機進行調整。自動糾偏是當偏斜超過一定值時,糾偏指令發生器發出指令,系統進行自動糾偏。電氣同步是在交流傳動中,常用帶有均衡電動機的電軸系統來實現電氣同步。

4, the cart running mechanism of the rectification and electrical synchronization. Deviation correction and automatic correction for artificial, man-made rectification is when the deviation exceeds a certain value, correcting signal generator signal, motor driver off ahead of the leg side, connecting leg partial motor lag adjustment. Automatic deviation correction is when the deviation exceeds a certain value, the error correction instruction generator sends out the instruction, the system carries on the automatic correction. Electrical synchronization is used in AC drive, often with a balanced motor shaft system to achieve electrical synchronization.

5、遼寧橋式起重機電磁鐵及其控制電路。主要是提供電磁鐵的直流電源及完成(吸、放料)控制要求。其工作方式分為定電壓和可調電壓兩種控制形式。

5, crane electromagnet and its control circuit. The main purpose is to provide DC power supply and complete (suction, discharge) control requirements. It can be divided into two control modes: constant voltage and adjustable voltage.
