Embodiment Construction
[0018] Further detailed explanation through specific implementation mode below:
[0019] The reference signs in the drawings of the description include: inner wall body 1, outer wall body 2, air hole 3, cylinder 4, air bag 5, piston 6, connecting rod 7, top 8, rotating shaft 9, air inlet 10, connecting pipe 11 , The second spring 12, the third spring 13, the slide block 14, the contact block 15, the chute 16, the indicator light 17, the valve 18, the ejector rod 19, the ejector block 20.
[0020] The embodiment is basically as attached figure 1 and figure 2 Shown:
[0021] There is a cavity between the outer wall 2 and the inner wall 1, and the inner wall 1 is provided with a fixedly connected sealing box 3, the sealing box 3 is made of plastic soft material, and the sealing box 3 is provided with two cylinders 4, An air bag 5 is arranged between the cylinders 4, and the air bag 5 communicates with the cylinder 4 through a connecting pipe 11. The connecting pipe 11 is made...

The invention belongs to the technical field of tunnel safety, and particularly relates to a suspended tunnel vehicle safe driving system which comprises a power source, an inner wall body and an outer wall body. A sliding groove is formed in the inner wall body; and the system further comprises an air bag and an air inlet. Cylinders are respectively arranged on two sides of the air bag; a communicating pipe is arranged between the air bag and the cylinders; a piston in sliding connection is arranged in the air cylinders; a rotationally connected connecting rod is arranged on the piston; a sliding block is arranged outside the air cylinders; the sliding block is slidably connected with the sliding groove; the air inlet is communicated with the air bag; a rubber ring is arranged in the airinlet; and the excircle diameter of the cylinder is equal to the distance between the inner wall body and the outer wall body. Aiming at a traditional detection device, power generated by deformationof a vacuum air bag when air is inflated is used for pushing an air cylinder to move, so that a connecting rod extends out under the mechanical action, on one hand, the vibration condition in a tunnelis detected, the vibration magnitude is judged, on the other hand, vehicles which do not run into the tunnel during vibration are stopped, and the danger is prevented.
Description
technical field [0001] The solution belongs to the technical field of tunnel safety, and specifically relates to a vehicle safety driving system for a floating tunnel. Background technique [0002] With the progress of society, the development of cities is increasing. For the closed environment in the mountains, in areas with higher altitudes and more mountains, for urban development, tunnels must be excavated on the mountains. For construction operations or vehicle driving in the tunnels , as well as ground vibration will have an impact on the vibration of the mountain and the tunnel itself. In tunnel engineering, it is often necessary to generate fluctuations on the surface of the engineering structure in an occasional vibration environment (such as vehicle vibration, far-field blasting, etc.) vehicles pose a safety hazard. When the construction process or the overall environment of ground vibration is in a state of vibration, it is difficult to obtain a horizontal static...
