橋梁檢測車為了提高安全系數，最直接簡單的辦法就是增加位于穩定部分的固定配重量，但隨著橋梁檢測車技術參數的增大以及質量參數的法規限制，簡單的增加固定配重量已經無法滿足安全系數的提升，當遇到橋面傾斜等工況時，安全系數降低，有可能造成車輛的傾翻事故，所以建議采取一些除增加固定配重之外的措施來提升橋梁檢測車的作業安全。

     

    　　In order to improve the safety factor, the most direct and simple way is to increase the fixed weight in the stable part. However, with the increase of the technical parameters of the bridge detection vehicle and the limitation of the quality parameters, the simple increase of the fixed weight can not meet the safety factor. When the safety factor is reduced, it is possible to cause the vehicle overturning accident, so it is better to take some measures to improve the operation safety of the bridge detection vehicle in addition to increasing the fixed counterweight.

     

    　　防傾翻控制系統的應用提升橋梁檢測車作業安全。

     

    　　The application of anti rollover control system improves the safety of bridge inspection vehicle.

     

    　　對于橫坡傾角α所帶來的橋梁檢測車的安全性問題，目前業界研制了一種防傾翻的裝置。與車架平臺調平系統不同的是，該裝置主要是通過控制傾翻部分相對于支點的力臂長度來減小傾翻力矩的。

     

    　　For the safety problem of bridge detection vehicle caused by the inclination angle of the cross slope, an anti-tipping device has been developed. Unlike the leveling system of the frame platform, this device mainly reduces the tilting torque by controlling the length of the tilting arm relative to the fulcrum.

     

    　　防傾翻裝置主要包括安裝于車輛尾端的控制器、車架平臺上的傾角傳感器、安裝在一回轉總成內的電磁換向閥、四連桿機構、調距油缸等。四連桿機構包括兩根相互平行的連接桿，調距油缸與連接桿成一定角度的傾斜。

     

    　　The anti-rollover device mainly includes the controller installed at the rear end of the vehicle, the inclination sensor on the platform of the frame, the electromagnetic directional valve installed in a rotary assembly, four-bar linkage mechanism, adjustable distance cylinder and so on. The four-bar linkage mechanism consists of two parallel connecting rods, and the adjustable distance cylinder and the connecting rod are inclined at a certain angle.

     

    　　工作原理為桁架式橋梁檢測車對橋面具有傾角α的橋梁進行檢測作業時，傾角傳感器檢測出橋面的傾角α，并通過線路將該傾角α的信息傳送至控制器，控制器經過處理，將傾角信號轉換為控制信號傳送至電磁換向閥，電磁換向閥做出相應動作，通過軟管使調距油缸的缸筒腔進油，調距油缸內的活塞伸出。在活塞伸出的作用下，傾翻部分的桁架結構共同向上平移，兩個連接桿同時發生傾斜，使桁架結構與支點之間的距離縮短，相應的傾翻力臂減小使傾翻力矩也相應減小，這樣就減少了桁架式橋梁檢測車在具有傾角的橋面上進行檢測作業時發生傾翻的風險。

     

    　　The working principle is that when the truss bridge detection vehicle detects the bridge deck with dip angle a, the dip angle sensor detects the dip angle a of the bridge deck and transmits the information of the dip angle a to the controller through the line. After processing, the controller converts the dip angle signal to the control signal and transmits it to the electromagnetic reversal valve. The valve makes the corresponding action, through the hose to adjust the distance cylinder cylinder cavity into the oil, adjust the distance cylinder piston out. Under the action of the piston extension, the truss structure of the tilting part moves upward together, and the two connecting rods incline at the same time, which shortens the distance between the truss structure and the fulcrum, and the corresponding tilting arm reduces the tilting torque accordingly, thus reducing the truss bridge detection vehicle on the deck with tilting angle. The risk of rollover is detected during operation.
