Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway engineering technology, specifically to a height and width limiting device for highways. Background Technology
[0002] With the gradual completion of the village-to-village road construction project, rural roads are gradually being paved. In order to protect the roads and extend their service life, some measures must be taken to restrict the passage of oversized and overweight vehicles.
[0003] There are two existing technical methods. One is to install width-limiting road piers on both sides of the road surface. This method has the advantages of low cost and easy manufacturing, but it does not have the function of limiting height, nor can the width limit be adjusted. The other is to set up height and width limit frames on the road surface. Traditional height and width limit frames have a rigid structure, which not only restricts the passage of oversized and overweight vehicles, but also restricts the passage of ambulances, fire trucks and police vehicles. Although it plays a protective role for the road, it poses a huge safety hazard and needs to be improved. Utility Model Content

[0009] An adjustable height limiting device is provided on one side of the inverted U-shaped frame;
[0010] The height limiting device includes a height limiting frame hinged to the top of an inverted U-shaped frame. A height limiting motor is symmetrically arranged inside the inverted U-shaped frame. The output end of the height limiting motor is provided with a screw. A screw block is provided on the screw and is provided with a connecting rod hinged to the screw block. The other end of the connecting rod is hinged to the height limiting frame.
[0011] As an improvement, one side of the inverted U-shaped frame is provided with symmetrically arranged elongated openings, and the connecting rod is located in the elongated openings.
[0012] As an improvement, the inverted U-shaped frame is provided with symmetrically arranged mounting plates, and the height limiting motor is mounted on the mounting plates.
