Description

Technical Field

[0001] The utility model relates to the technical field of road height limiting devices, in particular to a road height limiting frame. Background Art

[0002] Road height limit refers to the restriction on the vertical height of the road to ensure the safe passage of vehicles and pedestrians and protect road facilities from damage. The specific value of the road height limit is determined according to the type and grade of the road to ensure traffic safety and the normal operation of urban facilities. The restricted height can prevent large vehicles from causing damage to the road structure, extend the service life of the road, and avoid vehicles being unable to pass through low bridges or tunnels due to being too high, causing traffic accidents. In addition, lower height limits are set on some trails or specific sections to accommodate pedestrian passage or protect the road surface structure.

[0003] In addition, when performing height limit operations on the road surface, a road height limit frame will be used. During the actual use of the road height limit frame, some passing freight drivers may not be familiar with the height limit signs or misjudge the height of their own vehicles and choose to continue passing, which may cause collisions with the poles. In order to protect the height limit frame and ensure its normal use, and to reduce maintenance cycles and effort, a new road height limit frame needs to be designed. Utility Model Content

[0031] Example 2

[0032] See Figure 1-6 , and on the basis of Example 1, the lifting mechanism 3 is further obtained to include a vertical seat 31, the vertical seat 31 is fixedly connected to the top of the base 1, the top of the vertical seat 31 is fixedly connected to a motor 32, the bottom end of the motor 32 is fixedly connected to a screw rod 33, the surface of the screw rod 33 is fixedly connected to a threaded block 34, the side of the threaded block 34 is fixedly connected to a slide box 35, the bottom end of the slide box 35 is fixedly connected to a second spring 36, the bottom end of the second spring 36 is fixedly connected to a limiting plate 38, the top of the limiting plate 38 is fixedly connected to a round shaft 37, the top of the round shaft 37 is fixedly connected to the bottom end of the support seat 21, a limiting groove is provided inside the slide box 35, and the surface of the limiting plate 38 is slidably connected to the inside of the limiting groove.
