The movable tooth end pressing type telescopic device for the highway bridge comprises a main splicing tooth plate, an auxiliary splicing tooth plate and an elastic metal sheet, the bottom of the auxiliary splicing tooth plate is connected with an absorption belt, the bottom of the elastic metal sheet is provided with a hedging and impacting assembly, one end of the hedging and impacting assembly is connected with the main splicing tooth plate, and the other end of the hedging and impacting assembly is connected with the auxiliary splicing tooth plate. The other end of the hedging and impacting assembly is connected with the auxiliary splicing toothed plate, and the outer side of the hedging and impacting assembly is connected with a springing piece for springing the elastic metal sheets. According to the movable tooth end pressing type telescopic device for the highway bridge, the elastic metal sheets designed at the bottom of the main splicing tooth plate and the bottom of the auxiliary splicing tooth plate are used for receiving falling stones and the like, and the opposite impact assemblies are installed at the bottom of the main splicing tooth plate and the bottom of the auxiliary splicing tooth plate. The impact airflow generated by the opposite impact assembly drives the springing piece to springing the elastic metal sheet, the knocking piece is used for knocking the stones to the elastic metal sheet, and therefore the situation that the falling stones damage the absorption belt is reduced.
本发明公开了一种公路桥梁用活动齿端压紧式伸缩装置，包括主拼接齿板和从拼接齿板，弹性金属薄片，从拼接齿板的底部连接有吸收带，弹性金属薄片的底部设有对冲撞击组件，对冲撞击组件一端与主拼接齿板连接，且对冲撞击组件的另一端与从拼接齿板连接，对冲撞击组件外侧连接有弹动弹性金属薄片的弹动件；弹性金属薄片的两端分别设有敲击件，此公路桥梁用活动齿端压紧式伸缩装置，在主拼接齿板和从拼接齿板的底部设计的弹性金属薄片用以接受从掉落的石子等，对冲撞击组件安装在主拼接齿板和从拼接齿板底部，对冲撞击组件产生的冲击气流带动弹动件弹动弹性金属薄片，利用敲击件将石子敲击处弹性金属薄片，从而减少了掉落的石子损坏吸收带。
