  桥梁检测车为了提高安全系数,最直接简单的办法就是增加位于稳定部分的固定配重量,但随着桥梁检测车技术参数的增大以及质量参数的法规限制,简单的增加固定配重量已经无法满足安全系数的提升,当遇到桥面倾斜等工况时,安全系数降低,有可能造成车辆的倾翻事故,所以最好采取一些除增加固定配重之外的措施来提升桥梁检测车的作业安全。
 
  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.
 
  防倾翻控制系统的应用提升桥梁检测车作业安全。
 
  The application of anti rollover control system improves the safety of bridge inspection vehicle.
桥梁检测车
 
  对于横坡倾角α所带来的桥梁检测车的安全性问题,目前业界研制了一种防倾翻的装置。与车架平台调平系统不同的是,该装置主要是通过控制倾翻部分相对于支点的力臂长度来减小倾翻力矩的。
 
  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.
 
  防倾翻装置主要包括安装于车辆尾端的控制器、车架平台上的倾角传感器、安装在一回转总成内的电磁换向阀、四连杆机构、调距油缸等。四连杆机构包括两根相互平行的连接杆,调距油缸与连接杆成一定角度的倾斜。
 
  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.
 
  工作原理为桁架式桥梁检测车对桥面具有倾角α的桥梁进行检测作业时,倾角传感器检测出桥面的倾角α,并通过线路将该倾角α的信息传送至控制器,控制器经过处理,将倾角信号转换为控制信号传送至电磁换向阀,电磁换向阀做出相应动作,通过软管使调距油缸的缸筒腔进油,调距油缸内的活塞伸出。在活塞伸出的作用下,倾翻部分的桁架结构共同向上平移,两个连接杆同时发生倾斜,使桁架结构与支点之间的距离缩短,相应的倾翻力臂减小使倾翻力矩也相应减。?庋?图跎倭髓旒苁角帕杭觳獬翟诰哂星憬堑那琶嫔辖?屑觳庾饕凳狈⑸?惴?姆缦。
 
  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.
