Problems solved by technology
[0003] Among them, the traffic road conditions have downhill turns and uphill turns. The wet and slippery roads that are prone to occur in spring and winter can easily cause vehicles to lose control and skid. Traditional protective facilities Scratching or colliding directly with the vehicle cannot provide a gradual buffering effect, causing great damage to the vehicle and the facility is easy to dump

Embodiment Construction
[0014] A traffic safety protection mechanism for an interchange bridge, such as figure 1 and figure 2 As shown, it consists of two parts, one of which includes the buffer assembly and the other includes the erection assembly;
[0015] The buffer components described therein are as Figures 3 to 5 Shown include:
[0016] Positioning base plate 11, shaft 12, round rod I13, compression spring I14, seal seat 15, moving base plate 21, round rod II22, compression spring II23, buffer seat 31 and moving seat 32;
[0017] Further, you can refer to Figure 5 A shaft 12 is affixed to the left side of the rear end of the positioning substrate 11, an opening is provided at the front end of the positioning substrate 11, and two round rods I13 extending forward and backward are affixed to the positioning substrate 11, and the round rods I13 are located in the opening, A compression spring I14 is sheathed on the front and rear sides of the round rod I13, the seal seat 15 is detachably fi...

The invention relates to the technical field of traffic safety, in particular to an interchange traffic safety protection mechanism. Comprising a buffering assembly, the buffering assembly comprises a positioning base plate and a movable base plate connected with the positioning base plate, the movable base plate can elastically reset relative to the positioning base plate, the movement range of the movable base plate is an acute angle, one end of the positioning base plate is fixedly connected with a shaft, and the movable base plate is rotationally connected to the shaft; a shaft is arranged on the movable base plate, a torsion spring is arranged on the shaft so that the movable base plate can be unfolded relative to the positioning base plate to achieve elastic reset, a limiting part I is fixedly connected to the movable base plate, the limiting part I is used for abutting against the positioning base plate to limit the maximum unfolding angle, and the purpose is that the vehicle can be gradually buffered.
Description
technical field [0001] The invention relates to the technical field of traffic safety, in particular to a traffic safety protection mechanism for an interchange bridge. Background technique [0002] The interchange type overpass refers to the crossing mode in which the spanning structure is set to separate the intersecting road space, and the upper and lower roads are connected by ramps for turning vehicles. The overpass vehicle can turn and drive, all or part of the conflict point is eliminated, and the mutual interference of traffic in each direction is small. [0003] Among them, the traffic conditions include downhill turns and uphill turns. The wet and slippery roads that are prone to occur in spring and winter can easily cause vehicles to lose control and skid. Traditional protective facilities directly scratch or collide with vehicles, and cannot provide gradual buffering. , the damage to the vehicle is large, and the facility is easy to dump.
