The force will be concentrated on the line formed by the upper and lower bases, the movable connecting rod 6, and the hinge shaft 7. The force is uniform, can withstand the heavy load pressure of large and heavy vehicles, and run stably.

The number of second cylinders 3 arranged is 2-4, and the lifting actions of the lifting groups and the plurality of second cylinders 3 are synchronized.

[0035] In some specific embodiments, a second cylinder 3 is further provided between the two lifting groups. The second cylinder 3 is an auxiliary lifting cylinder. The cylinder body end of the second cylinder 3 is vertically located and connected to the load-bearing frame 9. The piston rod end of the second cylinder 3 is hinged to the hinge seat 12, and the hinge seat is fixed on the top wall connected to the inside of the lifting beam 110.

[0040] In specific use, according to the lifting device for pneumatic lifting speed bumps described in the utility model, intelligent automatic lifting can be realized by connecting to an intelligent control system. By connecting to an intelligent control system, intelligent perception and response to vehicle speed can be realized. In normal conditions, the speed bump sinks and the yellow light flashes, prompting the driver that there is an obstacle ahead and that he must slow down. When the vehicle approaches the speed measurement area, the ground sensing speed coil will detect the vehicle speed of the lane in real time and transmit the data to the control system. If the vehicle speed exceeds the set speed limit, the control system will maintain the obstacle state, causing the vehicle to feel bumpy and impose necessary penalties on speeding drivers. When the vehicle speed is lower than the speed limit, the speed bump rises and the prompt light turns green, allowing the vehicle to pass smoothly and without obstacles, avoiding unnecessary bumps that are passively punished for normally traveling vehicles, and making traffic management more rational.

[0041] As the core power component of pneumatic lifting speed reduction belt, the utility model product is widely used in the field of lifting speed reduction belt.

[0042] To sum up, with the help of the above-mentioned technical scheme of the utility model, through the optimization and improvement design of the product of the utility model, the moving link and the upper base and the lower base are stretched to the upper and lower sides and maintain a vertical line. The force will be concentrated on the line formed by the upper and lower bases, the moving link, and the hinge shaft, so as to achieve uniform force, can withstand the heavy load pressure of large and heavy vehicles, and run stably; in addition, the lifting group structure of the utility model product is a fully mechanical pneumatic structure, the mechanical connection is stable, the failure rate is greatly eliminated, and it is a multi-component assembly connection with high safety and stability, strong environmental adaptability, and the intrusion of sand, dust and rain will not affect the operation.
