Problems solved by technology
[0002] The height limit pole can better guarantee traffic safety, and it can play a good role in preventing vehicles from being super high and protecting road and bridge facilities. With the advancement of science and technology, people have higher and higher requirements for height limit poles. The height device is not convenient to adjust the height of the height limit pole according to the actual needs. For example, the applicable vehicles are often changed during lane control. The ordinary height limit device is very inconvenient to use and it is not convenient to meet people's needs. Therefore, we A height-adjustable height-limiting device for municipal bridges is proposed to solve the above problems

The invention relates to the technical field of municipal administration, and discloses a height-adjustable bridge height limiting device for municipal roads, which comprises a fixed pile, the upper surface of the fixed pile is fixedly connected with a fixed column, the upper end of the outer wall of the fixed column is sleeved with an adjusting mechanism, and a spring is arranged between the lower side of the adjusting mechanism and the fixed pile. The spring sleeves the outer wall of the fixed column, and the right side of the adjusting mechanism is fixedly connected with a height limiting rod, when the device is used, a friction plate is supported and deformed through an arc-shaped plate, the friction force between the friction plate and the fixed column can be increased, the position of the friction plate is locked, the friction plate cannot move, the cleaning mechanism can blow down dust and rust on the surfaces of a pressing plate and the friction plate, the long-time wear or erosion is avoided, when the device needs to be moved, pull ropes are reversely pulled to enable the connecting rod to move rightwards, the fixed column can be loosened, then the pull ropes on the two sides are pulled downwards together, the spring is deformed and contracted, or the pull ropes are loosened to enable the height limiting rod to ascend, and the purpose of conveniently adjusting the height of the height limiting rod can be achieved.
