Problems solved by technology

Vehicles often need to pass through railway bridges, highway bridges, tunnels and other roads during driving. Some roads are limited in height and travel, and there will be limited elevated roads in advance. At present, most of the elevated roads are fixed frame structures. Some super-high vehicles did not pay attention to the collision between the height-limiting frame in front and the height-limiting frame, which would cause damage to the vehicle and the height-limiting frame; it would even cause the frame to collapse, which not only caused economic losses, but also caused personal safety

Embodiment 1

[0023] as attached figure 1 And attached figure 2 As shown, the fixed height-limiting frame that cannot be damaged by collision includes a frame body, and the top of the frame body spans a buffer height-limiting beam 3. The buffer height-limiting beam 3 is rotatably connected with the frame body. During high crossbeam 3, buffer height limit crossbeam 3 can rotate. The frame includes two uprights 1, and the uprights 1 are triangular frame structures. The top of the column 1 is straddled by a fixed beam 6, and the bottom of the fixed beam 6 is hinged with a buffer height-limiting beam 3. The left and right sides of the buffer height-limiting beam 3 are provided with spring telescopic pins 8 correspondingly matched with the jacks 7 . The material of the buffer height-limiting beam 3 is reinforced concrete, and the outer surface of the buffer height-limiting beam 3 is covered with impact-resistant metal (stainless steel or special steel) material. An electric rotating mechani...

Embodiment 2

[0026] as attached image 3 And attached Figure 4 As shown, the fixed height-limiting frame that cannot be damaged by collision includes a frame body, and the top of the frame body spans a buffer height-limiting beam 3. The buffer height-limiting beam 3 is rotatably connected with the frame body. During high crossbeam 3, buffer height limit crossbeam 3 can rotate. The frame body includes two uprights 1, and the top front side of each upright 1 is connected with the buffer height-limiting beam 3 through a hinge 4, and the bottom surface 2 of the buffer height-limiting beam 3 is a smooth arc surface. The material of the buffer height-limiting beam 3 is reinforced concrete. The outer side of the bottom surface 2 of the buffer height-limiting beam 3 is wrapped with impact-resistant non-metallic (PEEK plastic or rubber and composite material or nylon or tetrafluoroethylene or polyethylene or pom or polyurethane, etc.) material. A hydraulic rotating mechanism is arranged below t...

Abstract

The invention discloses a fixed height limiting frame capable of keeping undamaged in collisions and belongs to the technical field of road traffic. The fixed height limiting frame capable of keeping undamaged in the collisions comprises a frame body; a buffering height limiting cross beam stretches across the top of the frame body; the buffering height limiting cross beam is rotationally connected with the frame body and has a buffering damping structure; and when an outside force impacts upon the buffering height limiting cross beam, the buffering height limiting cross beam can rotate to prevent the fixed height limiting frame from being damaged by using an avoidance type anti-collision principle. According to the fixed height limiting frame capable of keeping undamaged in the collisions, the buffering height limiting cross beam is movable and can effectively buffer collisions from passing ultrahigh vehicles so that the ultrahigh vehicles are protected and the whole height limiting frame is also protected; therefore, the fixed height limiting frame capable of keeping undamaged in the collisions is economic and safe.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to a fixed unbreakable overpass. Background technique [0002] With the development of urban construction, various construction vehicles have gradually increased, which has brought great pressure to traffic management. In particular, large construction vehicles have seized lanes at will, causing great damage to roads, especially viaducts, and causing serious damage to citizens' lives. Great harm. Vehicles often need to pass through railway bridges, highway bridges, tunnels and other roads during driving. Some roads are limited in height and travel, and there will be limited elevated roads in advance. At present, most of the elevated roads are fixed frame structures. Some super-high vehicles do not pay attention to the collision between the height-limiting frame in front and the height-limiting frame, which will cause damage to the vehicle and the height-limiting frame; Conte...
