Steel truss structure type height-limiting frame

The invention belongs to the technical field of bridge auxiliary facilities and particularly relates to a steel truss structure type height-limiting frame. The steel truss structure type height-limiting frame comprises height-limiting frame bodies which are arranged on the left side and the right side of a bridge; each height-limiting frame body comprises a bridge pier and a steel truss, and eachbridge pier comprises a lower bearing table, a retaining wall and an upper bearing table; the steel trusses are connected with the upper bearing tables of the bridge piers, and steel pipe piles are arranged on the lower portions of the lower bearing tables; and a flexible buffer sleeve is arranged outside each retaining wall. The steel truss structure type height-limiting frame has the beneficialeffects that high ships can be intercepted outside the height-limiting frame, and as for certain ships which collide with the height-limiting frame due to errors of height judgment, the height-limiting frame achieves the compu
