二、具体技术要求
Detail technical requirements
1．控制器显示菜单语言为中文和英文，顺槽控制主机和地面主机显示菜单为中文。
Display menu on controller is in both Chinese and English, gate control unit and surface computer display in Chinese.
2．制造满足10.5秒工作循环的主阀体。
Tiefenbachs main control valves are made to meet the cycle time of 10.5 seconds.
3．支架配置电液控制系统，能够完成支架的各种动作功能。支架可实现成组程序自动控制，包括成组自动移架、成组自动推溜、成组自动伸收护帮、成组自动伸收伸缩梁。支架可实现邻架电控的手动、自动操作，实现本架电磁阀按钮的手动操作。顺槽主控计算机可实现远程控制工作面液压支架动作，即跟机自动化功能（跟机自动移架、跟机自动推溜、跟机自动喷雾功能）。可实现成组自动移架和推溜，又可本架手动按钮、左右（1-3）邻架电控按钮控制、自动循环操作。
Shields are equipped with E-H control systems to be able to complete every action function of shields. Shield can realize group program automatic control including group au
tomatic moving shields, group automatic pushing conveyor, group automatic extending and retracting extension bar. Shield can finish manual, automatic operation of E-H controls of adjacent shields and the manual operation on solenoid valve button of local shield. Gate main computer can realize remote control for face shield actions, viz., following-Shearer automatic function (following-Shearer automatic moving shields, following-Shearer automatic pushing conveyor, following-Shearer automatic spraying function). And automatic moving and pushing can be achieved, meanwhile, the manual pushing button in local shield and right and left (1-3) hand of adjacent shields controlled by E-H control button, and automatic cycling operation.
4．配备红外线接收装置，可与工作面采煤机实现联合动作。同时具备接收采煤机数字信号实现联动功能。支架能满足与采煤机、刮板机进行自动割煤要求，在三角煤区域也能实现自动拉架。
The infrared receiver device is equipped, to be able to complete the associated action with face Shearer. Meanwhile, it should be with the function of receiving signal data of Sh
earer to complete associatedly action. Shields meet the requirement of auto coal-cutting with Shearer and scraper conveyor, to complete the function of auto shield pulling in triangle mine area.
5．对立柱的工作压力、推移千斤顶的行程、煤机的位置、方向等进行监测和数据传输。能将数据传输至地面控制中心并显示。
To monitor and transfer data for the working pressure of leg, stroke of advancing ram, position and direction of Shearer and etc. To be able to transfer data to surface control center and display.
6．电液控制系统设有声音报警、急停、本架闭锁及故障自诊断显示功能，并能方便地进行人工手动操作。
E-H control system is set with sound alarm, quick-stop, local shield lockout and self diagnose and display, also should be convenient for manual operation.
7．供电电压为 AC 127V 50Hz。
The power supply voltage is AC 127V 50Hz/12V.
8．电控装置外壳防护等级不低于IP67。
E-H equipment housing’s protection level should be not lower than IP67.
9．电控系统为非主-从机型，当工作面控制系统与顺槽控制中心断开后，仍能完成各种操作功能。没有顺槽计算机就无法实现自动功能。
E control system is NOT Master-slaver type, when face control system disconnects to gate control center, it should aslo be able to complete any operating functions. No automatic function without Head gate computer
10．支架所有动作功能由电磁阀驱动。
All functions of shield can be driven by solenoid valve.
11．主阀组为整体式，阀芯采用插装式。
Main valve set is integral type, cartridge is adopted with plug-in type.
12．应具备与采煤机配合进行全自动化的双向、单向、部分截深割煤功能。
It should have the cutting function of automatic double-way, single-way, part cutting depth assorting with Shearer.
13．通过电液控制系统能配合采煤机实现自动喷雾。
It can assist Shearer to realize automatic spraying by E-H control system.
