Obtain support plate and an inclined slope is formed on road surface, and then stop that the vehicle being forced through continues to travel, avoid its escape, it is convenient
Law enfrocement official carries out violation processing；The dual limitation of restrictor bar and support plate coordinates severe law enforcement dynamics to reduce overload traveling
Situation, ensures the permanent use of highway pavement, after being punished to overloaded vehicle or its load-carrying is back to normal horizontal, by holding
Method personnel show radio frequency card, and after being identified in card reader, restrictor bar normally raises so that vehicle passes through.
Multiple cylinder B are further included, cylinder B is placed in the bottom of foundation pit, and the support plate is provided with multiple through holes, is slided in through hole
It is provided with gag lever post, the output terminal of gag lever post and cylinder B.Multiple gag lever posts on the supporting plate are dashed forward running into overloaded vehicle by force
When broken, rising rapidly under the effect of the upper top of cylinder B so that driver can in time see and vehicle is braked, into
One step hinders travelling again for overloaded vehicle, ensures the function traveling of overload sense channel.
Multiple through hole rectangular array distributions are on the supporting plate.
Spacing between the gravity sensor and restrictor bar is 4~6m.Spacing between gravity sensor and restrictor bar is located at 4
In the range of~6m so that for gravity sensor after having identified, hydraulic cylinder has enough time so as to obtain restrictor bar rising, ensures vehicle
Normal through while reduce vehicle parking time, avoid traffic congestion, that improves sense channel passes through efficiency.
Compared with prior art, the present invention have the following advantages and advantages：
1st, the present invention is when overweight vehicle rolls away from by force, headstock and travel switch making contact, travel switch control cylinder A
Upper top, drives support plate to move up so that support plate forms one inclined slope on road surface, and then the vehicle that is forced through of stop after
Continue and sail, avoid its escape, facilitate law enfrocement official to carry out violation processing；The dual limitation of restrictor bar and support plate coordinates severe hold
Method dynamics ensures the permanent use of highway pavement to reduce the situation of overload traveling, when overloaded vehicle is punished or its
After load-carrying level back to normal, radio frequency card is shown by law enfrocement official, after being identified in card reader, restrictor bar normally raises,
So that vehicle passes through；
2nd, the spacing between gravity sensor and restrictor bar of the invention is located in the range of 4~6m so that gravity sensor
After having identified, hydraulic cylinder have enough time so as to obtain restrictor bar rise, ensure vehicle normal through while reduce vehicle stop
The time leaned on, traffic congestion is avoided, that improves sense channel passes through efficiency.
