The invention relates to the technical field of road height limitation, in particular to an anti-collision type road height limiting frame. The anti-collision type road height limiting frame comprisessupporting boards, a weight control mechanism, a monitoring mechanism, a height limiting mechanism, a height measuring mechanism, a transmission mechanism and a reminding mechanism. An active infrared intrusion detector is installed in a first fixing seat, buzzer alarms are installed in a second fixing seat and a third fixing seat, once a truck exceeds the height, the buzzer alarms can be startedas soon as possible to remind a driver of the truck that the truck exceeds the height, meanwhile, a buffering distance exists between the height measuring mechanism and the height limiting mechanism,the driver can effectively make a response to stop the truck, and the truck is prevented from hitting a height limiting rod. The height is limited, meanwhile, a speed reduction lever can be effectively used for limiting the speed and the weight, once the truck is overweight, an alarm can be given as soon as possible, a camera function is started, and illegal and irregular actions can be conveniently traced to take evidence. The height of the height measuring mechanism and the height of the height limiting mechanism can be adjusted and can be accurately kept identical all the time, the width of the height limiting mechanism is controllable, and autonomous integrated control is fully achieved.
