Technical Field

The invention relates to the field of building construction, in particular to a highway overload detection method.

Background

Vehicle loading is one of the important factors to be considered for highway design, maintenance and long-term use. At present, in the road traffic of China, the condition that the road surface is seriously damaged due to the overload of vehicles is increasingly serious. Weight-limiting law enforcement is therefore a powerful measure to prevent overloaded vehicles from damaging the road.

Disclosure of Invention

The present invention is directed to a method for detecting overload on a highway, so as to solve the above problems.

The purpose of the invention is realized by the following technical scheme:

a highway overload detection method comprises the following steps: (A) when the cargo vehicle passes through the gravity sensor in front of the brake rod, the gravity sensor detects the total load of the vehicle body, when the total cargo quantity is combined, the gravity sensor transmits a signal to the hydraulic cylinder, the output end of the hydraulic cylinder moves downwards to drive the brake rod to move upwards, and the vehicle normally passes through the road surface; (B) when the total cargo loading amount exceeds the standard amount, the gravity sensor transmits a signal to the hydraulic cylinder, the hydraulic cylinder does not work, the brake lever keeps the horizontal position, and law enforcement personnel process the overweight vehicle; (C) when a few overloaded vehicles do not attach importance to the brake bar for limiting the driving, the vehicles can directly drive through the brake bar after overload is detected, the travel switch is arranged in the middle of the brake bar, when the overloaded vehicles drive out forcibly, the vehicle head collides with the travel switch, the travel switch controls the cylinder A to jack up, the support plate is driven to move upwards, an inclined slope is formed on the road surface by the support plate, the vehicles which pass by forcibly are prevented from continuing to drive, escape of the vehicles is avoided, and law enforcement personnel can conveniently carry out violation treatment; in the above-mentioned step the output hinged joint of pneumatic cylinder has the brake lever, the brake lever is articulated with the stand, install the read write line on the outer wall of stand, the read write line passes through the controller and is connected with the pneumatic cylinder, mid-mounting at the brake lever has travel switch, still including arranging gravity sensor and the backup pad on the both ends road surface around the brake lever in respectively, gravity sensor is connected with the pneumatic cylinder, the backup pad is arranged in the foundation ditch, and gravity sensor and backup pad and road surface keep the level, the one end and the foundation ditch inner wall of backup pad are articulated, the other end of backup pad is articulated with cylinder A's output, travel switch is connected with cylinder. According to the invention, the double limitation of the brake lever and the supporting plate is matched with strict law enforcement force to reduce the overload driving condition and ensure the long-term use of the road surface, when an overloaded vehicle is punished or the load returns to a normal level, a law enforcement officer shows the radio frequency card, and after the radio frequency card is identified on the card reader, the brake lever is normally lifted, so that the vehicle can pass smoothly.

Still include a plurality of cylinders B, cylinder B arranges the bottom in the foundation ditch in, the backup pad is opened has a plurality of through-holes, and it is provided with gag lever post, gag lever post and cylinder B's output to slide in the through-hole. When a plurality of limiting rods on the supporting plate are subjected to forcible breakthrough of an overloaded vehicle, the limiting rods rapidly ascend under the action of the upper top of the cylinder B, so that a driver can see and brake the vehicle in time, the overloaded vehicle is further prevented from running again, and the function running of an overload detection channel is ensured.

The through holes are distributed on the supporting plate in a rectangular array.

The distance between the gravity sensor and the brake rod is 7-10 m. The interval between gravity sensor and the brake bar is established at 7 ~ 10 m's within range for gravity sensor has enough time to make the brake bar rise after the discernment, reduces the time that the vehicle was berthhed when guaranteeing the normal passing through of vehicle, avoids traffic congestion, improves the efficiency of passing through of detection passageway.

Compared with the prior art, the invention has the following advantages and beneficial effects:

1. when the overweight vehicle is forcibly driven out, the vehicle head collides with the travel switch, the travel switch controls the cylinder A to push upwards to drive the support plate to move upwards, so that the support plate forms an inclined slope on the road surface, the vehicle which is forcibly passed is prevented from continuously driving, the escape of the vehicle is avoided, and law enforcement personnel can conveniently carry out violation treatment; the double limitation of the brake lever and the supporting plate is matched with strict law enforcement force to reduce overload driving conditions and guarantee long-term use of a road surface, when an overloaded vehicle is punished or the load returns to a normal level, a law enforcement officer shows a radio frequency card, and after the overload vehicle is identified on a card reader, the brake lever is normally lifted, so that the vehicle can pass smoothly;

2. according to the invention, the distance between the gravity sensor and the brake rod is set within the range of 7-10 m, so that after the gravity sensor is identified, the hydraulic cylinder has enough time to lift the brake rod, the normal passing of a vehicle is ensured, the time for the vehicle to stop is reduced, the traffic jam is avoided, and the passing efficiency of a detection channel is improved.
