DRD控制技术优势 Advantages of DRD control technology


1.定量推溜,DRD支架电液控制系统采用独特的硬件设计和精确的软件处理算法,可实现支架进行推移时推移精度小于8mm。

2.定量拉架,DRD通过软件算法和贴近实际的控制工艺很好改善了这一问题,使得拉架误差小于10mm。

3.采煤机定位,因DRD本着精简设计的理念,在采煤机上安装一个红外线发射器即可实现对采煤机位置的定位。

4.支架姿态与高度的测量,通过倾角传感器和 针对性设计的算法能够很好的 监测支架的姿态和高度。支架 倾角测量精度高达0.1度,高度  测量误差小于2cm。

5.支架自动补液功能,电液控制系统能够实现在立柱压力下降后控制支架压力自动补充,对安全支护起到很好监控。若支架多次出现泄液不能保压的情况,集控软件将会出现错误报警,对安全生产提供了进一步的保障,且易于设备维护。

6.自动跟机喷雾,可实现对采煤机的动态覆盖式喷雾,能有效的起到除尘的作用。

7.安全系数高的控制工艺,渐进式的成组推溜功能与增量式的向后拉溜功能。

8.远程控制,基于Profibus 总线技术的DRD支架电液控制  系统远程控制功能,已成功、稳定的在多个工作  面进行使用。用户根据现场情况的实际需要操作  支架动作的各个功能、设定动作时间、启动各种  成组控制功能,包括斜切进刀等全自动开采功能。

9.割三角煤控制工艺,可以实现采煤机和刨煤机在工作面两端头的反向斜切进刀、割三角煤、反复清浮煤、支架S弯的自动控制、支架超前支护的控制和自动跟机推溜等功能。

10.工作面压力检测,DRD利用支架电液控制系统可实现对工作面压力数据的处理,并进行可视化显示,对帮助煤矿分析工作面开采过程中的顶板压力,提高生产的安全性具有较大帮助。

1. Quantified pushing conveyor: DRD’s electro-hydraulic control system adopts unique hardware design and accurate software processing algorithm, which can realize the displacement accuracy of the bracket less than 8mm during pushing conveyor.

2. Quantified pulling shield: DRD improves the problem well through software algorithm and practical control technology, making the error of pulling shield less than 10mm.

3. Shearer positioning: Based on the concept of simple design, the location of the shearer can be located by installing an infrared transmitter on the shearer. 

4. Monitoring the status and measuring and height of the support: The status and height of the support can be well monitored by means of the inclination sensor and the algorithm designed specifically.The measuring accuracy of support inclination angle is up to 0.1 degree, and the measuring error of height is less than 2cm.

5. Support automatic rehydration function: The electro-hydraulic control system can automatically replenish the support pressure after the column pressure drops, which can monitor the support’s safety well. If the support fails to maintain pressure due to the discharge of liquid for many times, the centralized control software will give a false alarm, which provides further guarantee for safe production and is easy to maintain the equipment.

6. Automatically following-Shearer spay: It can realize the dynamic covering spray on the shearer, which can effectively play the role of dust removal.

7. High safety control technology: The function of progressive group pushing conveyor and incremental rear conveyor.

8. Remote control: DRD’s support electro-hydraulic control system is based on Profibus technology, and it has been successfully and stably used on many longwalls. According to the actual needs of the mine’s situation, the user operates various functions of the bracket action, sets the action time, and starts various group control functions, including automatic mining functions such as oblique cutting feed.

9. The technology of cutting triangle coal: It can realize the following functions: reverse oblique cutting feed of shearer and plough at both ends of working face, cutting triangle coal, repeatedly cleaning floating coal, automatic control of s-bend of support, control of lead support of support and automatic following-Shearer pushing conveyor.

10. Pressure testing on the longwall: The electro-hydraulic control system can process the pressure data of the longwall and make a visual display, which is of great help to analyze the roof pressure in the mining process of the longwall and improve the safety of production.
