The tilt sensor is an important part of all parts of the full section tunnel boring machine. It can measure the tilt angle of the body of the shield machine and the tilt angle of the mining cavity, and calculate the distance of the mining deviation through a series of complex operations, which plays a very important role in correcting the guidance.
In the past, the drilling and blasting method is widely used in mountain tunnel hard rock tunneling, but under the same conditions, the tunneling speed of the full section tunnel boring machine is about 8 times that of the drilling and blasting method, which has the advantages of high efficiency, fast, high quality, safety, economy and environmental protection.
The driving principle of hard rock tunnel boring machine is that the knife rotates and the pressure hob acts on the tunnel palm surface. The hob rotates on the palm surface to loosen the surrounding rock. The excavated stone slag is collected by the side scraper and enters the belt conveyor through the slag bucket, and then the belt conveyor transports the stone slag along the boring machine to the end, and finally the stone slag is loaded onto the slag truck for transport.
The slightest difference is a thousand miles, some tunnels are very long, and the small gap may be a trouble in the later period, so the accuracy of the tunnel boring machine is very high. Not only that, the tunnel environment is humid, the temperature difference is different, and the vibration of the tunnel boring machine is strong.
The ER-TS-3266DI tilt sensor produced by Ericco fully considers the above situation, especially optimized circuit protection and program protection in vibration resistance, so as not to make the sensor unable to work because of excessive vibration. After testing, the long-term stability reaches 0.05° and has a high resolution of 0.0025°, with IP67 waterproof grade, which can be used in underground humid environment, and the wide temperature working -40~+ 85°C can also meet most practical conditions. It can be seen that the ER-TS-3266DI tilt sensor produced by Ericco is competent for the role of the boring machine direction test control, and its performance parameters are as follows:
① Range +15°, +30°
② Wide voltage input 9~36V
③ Wide temperature operation -40~ +85°C
④ High vibration resistance>20000g
⑤ High resolution 0.0025°
⑥ Waterproof grade IP67, strong ability to resist external electromagnetic interference.
⑦ can be adjusted and set for vibration suppression on site.
