Abstract
The utility model discloses an energy dissipation device for a double-pole traffic sign, comprising an upper energy dissipation component and a lower energy dissipation component. The upper energy dissipation is arranged at the upper part of an upright post and under a sign board while the lower energy dissipation component is arranged at the bottom of the upright post and between a flange and a base flange. With the reasonable design and simple structure, the utility model can be used on the traffic sign of the highway to reduce the harm on the car and the people in the car, which is caused by the collision on the traffic sign.
Description
Technical field
The utility model relates to a kind of freeway traffic sign, particularly a kind of energy dissipator that is used for the twin columns traffic sign.
Background technology
Current, domestic design and being provided with about the freeway traffic sign also all rests on the big characteristics of intensity height, safety factor, collision accident to vehicle and sign is not considered as yet, though external existing correlation technique, but also existing the facility parts makes trouble, and, need the tailor-made problems such as column that are consistent with it, and can not be applied in easily on the current domestic highway because of the stress surface of bump is the region direction deficiency.At present domestic present situation, the traffic sign facility is provided with disintegration energy dissipation type device, use the energy dissipation type member existing sign column is improved, can reach the effect that reduces accident injury, meet the transport development theory that people-oriented.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of reasonable in design, simple in structure, can reduce the energy dissipator that is used for the twin columns traffic sign that vehicle and driver and crew is damaged because of collision.
The technical solution of the utility model is: a kind of energy dissipator that is used for the twin columns traffic sign, it is characterized in that: it is made of top energy dissipation component 10 and bottom energy dissipation component 9, top energy dissipation component 10 is installed in column 11 tops and is positioned at the below of mark plate 15, and bottom energy dissipation component 9 is installed between column 11 flange in the bottom dishes 12 and pedestal 14 flange 13.
The utility model compared with prior art has the following advantages: the utility model is reasonable in design, simple in structure, because the utility model adopts the fragile material of certain intensity and ductility to make according to designing requirement, and be provided with have the fracture plane of weakness the frangibility element, therefore, used as the connector of freeway traffic sign column, can effectively reduce the injury that vehicle and driver and crew is caused because of the collision blip accident.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is made of top energy dissipation component 10 and bottom energy dissipation component 9, top energy dissipation component 10 is installed in column 11 tops and is positioned at the below of mark plate 15, and bottom energy dissipation component 9 is installed between column 11 flange in the bottom dishes 12 and pedestal 14 flange 13.
As shown in Figures 2 and 3, described bottom energy dissipation component 9 comprises lower joint sleeve pipe 1 and last connecting bolt 2, be provided with frangible connectors 3 between last connecting bolt 2 and the lower joint sleeve pipe 1, lower joint sleeve pipe 1 is provided with internal thread, and the cross section of frangible connectors 3 is respectively less than the cross section of lower joint sleeve pipe 1 and last connecting bolt 2; Lower joint sleeve pipe 1, last connecting bolt 2 and frangible connectors 3 are positioned on same the axis.
As shown in Figure 4 and Figure 5, described top energy dissipation component 10 comprises a circular cylinder body 6, is positioned on the centre position of cylindrical shell 6, is provided with easy fracture band 7 along the barrel circumference, the thickness of easy fracture band 7 radially respectively is provided with two pairs of bolts hole 8 less than the thickness of cylindrical shell 6 on the cylindrical shell 6 of easy fracture band 7 both sides; The center line of described two pairs of bolts hole 8 is vertical mutually.
The utility model adopts the fragile material (such as heat treatment ductile iron) of certain intensity and ductility to make, be applicable to the two column traffic signs on the speedway, during its work, bottom energy dissipation component 9 is in order to connect column 11 flange in the bottom dishes 12 and pedestal 14 flange 13, last connecting bolt 2 is connected with the flange 12 of column 11 bottoms, and lower joint sleeve pipe 1 is connected with pedestal flange 13 bolts; Top energy dissipation component 10 is in order to connect the mark plate 15 of column 11 tops and column 11 tops.When column 11 was subjected to Vehicular impact, the fracture immediately of the frangible connectors 3 of bottom energy dissipation component 9, the easy fracture band of top energy dissipation component 10 7 was toppled over column 11, thereby is alleviated the collision to vehicle, helps driver and crew's safety.
The design of easy fracture band 7 and frangible connectors 3 is key points of the utility model design, Material Used mechanics, structural mechanics principle and Finite Element Simulation Software, on the basis of considering various existing factors, it is calculated, adopt in the design and have the value of quite safe coefficient, this value can satisfy at ordinary times, and deadweight, wind carry, ice the safe floor value of carrying, satisfy again simultaneously under certain vehicle is impacted, column can fracture and can not cause the last dividing value of excessive damage to vehicle.
