Road and bridge traffic height limiting device based on municipal buildings

Abstract

The invention provides a road bridge traffic height limiting device based on municipal buildings. The road bridge traffic height limiting device comprises a frame structure. A height limiting structure is hinged to the frame structure, and a rotary drum structure is installed at the tail end of the height limiting structure. A buffer structure is arranged on an outer side surface of the height limiting structure, and a balance weight structure is connected and installed on the buffer structure. A protection structure is arranged on the inner side of the height limiting structure; The frame structure comprises fixing seats, fixing holes, a mounting frame and a mounting plate, the mounting frame is welded and fixed to the mounting plate, reinforcing ribs are additionally mounted at the position, welded to the mounting plate, of the mounting frame, the mounting plate is rotatably mounted on the fixing seats, a row of fixing holes distributed in a 180-degree annular column shape are formedin the fixing seats, and the fixing seats are fixed to the ground. A mounting cylinder is hinged to the top of the mounting frame so that the connecting rod mounted on a mounting block can swing outwards, and the connecting rod can be directly ejected open in case of brake failure and the like of the vehicle so that the vehicle cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of municipal buildings, and more specifically relates to a traffic height limiting device for roads and bridges based on municipal buildings. Background technique [0002] There are two types of height-limiting racks: fixed height-limiting racks and adjustable height-limiting racks; fixed height-limiting racks are further divided into fixed integrated height-limiting racks and fixed crash-resistant height-limiting racks. The fixed one-piece height-limiting shelf is a one-time non-adjustable height-limiting shelf, which intercepts vehicles by the shelf itself. The fixed-type undamaged high-limiting shelf must be lifted by external force, such as a crane, to achieve vehicle passage in an emergency; the fixed one-piece high-limiting shelf is mainly used The portal frame at the entrance of bridges, culverts, and tunnels is generally welded by steel structure, which plays the role of protecting bridges, culverts,...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a road and bridge traffic height limiting device based on municipal buildings to solve the inconvenience that the existing limited elevated roads need to be dismantled as a whole to be released in special cases, and at the same time, when the vehicle driver does not pay enough attention to the height of the vehicle , Passing directly through the height-limited highway will cause the vehicle to be stuck in the height-limited highway, causing traffic inconvenience, while taller vehicles will directly destroy the height-limited highway and other phenomena.
