Balance weight buffering type height limiting frame

Abstract

The invention relates to a balance weight buffering type height limiting frame, and belongs to the field of highway facilities. The balance weight buffering type height limiting frame comprises stand columns separately standing on the two sides of a highway, two guide rails are fixed to the upper ends of the two stand columns respectively and are parallel, and a height limiting rod is arranged in the two guide rails. A first pulley and a second pulley are arranged on the outer sides of the guide rails respectively, and the first pulley is located in front of the original position of the height limiting rod. One end of a steel cable is fixed to the height limiting rod, and the other end of the steel cable winds across the first pulley and the second pulley and then is connected with a balance weight. The balance weight is arranged in a deep well below the second pulley, and the gravity of the balance weight is used for providing buffer for the height limiting frame, so that direct collision between vehicles and the height limiting frame is avoided, damage to the height limiting frame and the vehicles is reduced, and personal safety of drivers is guaranteed.

Description

technical field [0001] The invention relates to a weight-buffered height-limiting overhead shelf, which belongs to the field of highway facilities. Background technique [0002] In roads, culverts, bridges and railways running through the road, in order to ensure the safety of vehicles, protect public facilities, and prevent vehicles with high heights from damaging bridges and other facilities on the road surface, a height limit will be set up at the corresponding position. To indicate the height limit, ordinary height limiters fix two columns on both sides of the road, and connect them to the two columns through a horizontal height limit rod, but this kind of height limiter has many inconveniences: the height limiter usually has a limited height Tips, but some may not attract the attention of the driver, or the driver has a fluke mentality, but he is not sure about the overall height of his own vehicle (such as an overloaded vehicle), and it is easy to crash into the height...

[0002] In roads, culverts, bridges and railways running through the road, in order to ensure the safety of vehicles, protect public facilities, and prevent vehicles with high heights from damaging bridges and other facilities on the road surface, a height limit will be set up at the corresponding position. To indicate the height limit, ordinary height limiters fix two columns on both sides of the road, and connect them to the two columns through a horizontal height limit rod, but this kind of height limiter has many inconveniences: the height limiter usually has a limited height Tips, but some may not attract the attention of the driver, or the driver has a fluke mentality, but he is not sure about the overall height of his own vehicle (such as an overloaded vehicle), and it is easy to crash into the height limit. Not only the driver is easily injured, but also the Limited overhead damage

When the height limit frame is damaged, the height limit rod is usually bent and the column is tilted. It is necessary to remove the height limit frame and reinstall the height limit frame, which increases the maintenance cost.
