Question

帮忙翻译一下，谢了~

The shutter can be found in this rear gob shield. It is moved by two cylinders accessible in the opening (red arrow). The top steel plate of the rear gob shield is also accessible in this space.The adjacent photograph shows this opening.There are two possible locations for fitting the sensor. Either on the back wall of the rear gob shield (blue arrow) or on a flange (side wall, yellow arrow). The “yellow arrow” location would also show a signal from the forces of the pivot bearing. These forces would have different measurements depending upon the direction in which the sensor is mounted. The frequency of these forces will lie at around 50 Hz. It would perhaps be possible to recognise an extra load caused by coal or rock from this signal.
The “blue arrow” location would show the noise caused by sliding or thudding most clearly.
Preparations for mounting the sensor
The sensor itself has a plug-in connector. This connection is, however, not suitable for attaching a longer, heavy cable. The cable must therefore be held by a cable clamp close to the sensor. It was agreed upon the following for this fitting:
· a threaded bolt welded onto the shield (screw DIN 933 - M12x16) (see above sketch).
· sensor measurement, design and mounting (see centre sketch)
· the cable is fitted with a hose for the majority of its length. The protective hose stops close to the sensor. The cable is held here by a clamp (see the cable end in the lower part of the sensor sketch).
Additional equipment necessary for automation
In order to actually run and set the shield automatically, the inclination of the shutter must also be controlled.
We had already experienced difficulties here in the initial alignment. The programme was modified for the first installation so that the front legs were set to begin with. The back legs were set at low pressure or set later. This algorithm was altered as the majority of coal above the shield was already broken.
The new shield is fitted as a 2-leg shield. An inclinometer is required to control the steering cylinders and/or to control the automatic setting of the legs. It ensures that the shutter supports the coal - particularly at the end.
We use the inclinometer suitable for this purpose in horizon control for plough installations. To mount the sensor in the shield we would recommend using a magnet holder.

快门中可以找到这个后方采空区盾牌。这是感动了两个汽缸可以在开幕式（红色箭头） 。顶端钢板的后方采空区盾构也可在这space.The相邻照片表明，该opening.There有两种可能的地点，合适的传感器。无论是在回墙后方采空区屏蔽（蓝色箭头）或法兰（侧墙，黄色箭头） 。的？ ？黄色箭头？ ？位置也显示出信号的力量枢轴轴承。这些部队将有不同的测量取决于方向传感器安装。的频率，这些部队将由约50赫兹。或许有可能承认额外负荷引起的煤岩从这个信号。
“蓝色箭头”位置将显示造成的噪音滑动或thudding最清楚。
准备安装的传感器
传感器本身的插件连接器。这方面，但不适合长期重视，重型电缆。电缆，因此必须由一个电缆钳接近传感器。据商定下列此拟合：

*线程螺栓上焊接的屏蔽（螺钉标准933 - M12x16 ） （见上面示意图） 。
*传感器测量，设计和安装（见中心素描）
*电缆装有软管的大部分篇幅。保护管站接近传感器。该电缆是在此间举行的钳（见电缆结束在较低的部分传感器素描） 。
所必需的附加设备自动化
为了实际运行，并设置自动屏蔽，倾斜的快门也必须得到控制。
我们已经在这里遇到困难的初始对准。该方案修改为在第一次安装，以便使前腿被设置为开始。的后腿设定为低气压或更高版本。该算法改变，因为大多数煤以上的盾构已经打破。
新的屏蔽装置， 2腿盾牌。一个斜需要控制指导气瓶和/或控制的自动设置的腿。它确保快门支持煤炭-尤其是在年底。
我们使用倾斜适合这一目的的地平线控制犁设施。装载传感器在盾构我们会建议使用一种磁体持有人。
