DRD控制技術優勢 Advantages of DRD control technology


1.定量推溜,DRD支架電液控制系統采用獨特的硬件設計和精確的軟件處理算法,可實現支架進行推移時推移精度小于8mm。

2.定量拉架DRD通過軟件算法和貼近實際的控制工藝很好改善了這一問題,使得拉架誤差小于10mm。

3.采煤機定位,因DRD本著精簡設計的理念,在采煤機上安裝一個紅外線發射器即可實現對采煤機位置的定位。

4.支架姿態與高度的測量通過傾角傳感器和 針對性設計的算法能夠很好的 監測支架的姿態和高度。支架 傾角測量精度高達0.1度,高度  測量誤差小于2cm。

5.支架自動補液功能,電液控制系統能夠實現在立柱壓力下降后控制支架壓力自動補充,對安全支護起到很好監控。若支架多次出現泄液不能保壓的情況,集控軟件將會出現錯誤報警,對安全生產提供了進一步的保障,且易于設備維護。

6.自動跟機噴霧,可實現對采煤機的動態覆蓋式噴霧,能有效的起到除塵的作用。

7.安全系數高的控制工藝,漸進式的成組推溜功能與增量式的向后拉溜功能。

8.遠程控制基于Profibus 總線技術的DRD支架電液控制  系統遠程控制功能,已成功、穩定的在多個工作  面進行使用。用戶根據現場情況的實際需要操作  支架動作的各個功能、設定動作時間、啟動各種  成組控制功能,包括斜切進刀等全自動開采功能。

9.割三角煤控制工藝,可以實現采煤機和刨煤機在工作面兩端頭的反向斜切進刀、割三角煤、反復清浮煤、支架S彎的自動控制、支架超前支護的控制和自動跟機推溜等功能。

10.工作面壓力檢測,DRD利用支架電液控制系統可實現對工作面壓力數據的處理,并進行可視化顯示,對幫助煤礦分析工作面開采過程中的頂板壓力,提高生產的安全性具有較大幫助。

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.
