Description

Height limiting frame Technical Field The application relates to the technical field of power grid construction, in particular to a height limiting frame. Background In the construction site of the power grid overhead line, a height limiting frame is required to be built to limit the height of vehicles coming and going, so that the vehicles with excessive height are prevented from contacting or colliding with the overhead line to cause potential safety hazards. However, for temporary traffic demands of vehicles with a portion of the height exceeding the limit height, the limit height is often not met. In the conventional technology, the height limiting frame is usually required to be removed for temporary passing of vehicles with height exceeding the height limit, however, the mode usually requires a great deal of manpower to remove the height limiting frame, and when the vehicles pass, the height limiting frame needs to be installed back to the original position again with great deal of manpower, so that the process is complicated. Disclosure of utility model Based on this, need to need a large amount of manpower dismouting limit for height frame in order to highly exceed the interim traffic of limit for height in the conventional art, and then lead to the loaded down with trivial details problem of process, provide a limit for height frame.
