Description

Packaged narrow strip high-speed weighing device

Technical Field

The utility model relates to a narrow strip high-speed weighing device especially indicates a high-speed weighing device of encapsulation formula narrow strip.

Background

At present, the overload phenomenon of trucks in China is common, and researches show that when the axle load of a truck exceeds one time of the standard load, the truck runs on a road once, namely a standard vehicle runs on an asphalt pavement 256 times and runs on a cement concrete pavement 65536 times, and the damage of the overload on the road is more serious for the vehicle with larger rated load. In many roads built by huge capital investment, the phenomena of cracking, pit and groove, sinking, slurry turning, rutting, bridge pavement and breaking, plate body fracture and the like appear on the road surface as early as the rolling of overloaded vehicles, and huge capital investment is required to be carried out for maintenance every year; meanwhile, the overload damages the road, so that the running speed of the vehicle is influenced, and some overloaded vehicles can creep at the speed of only one and twenty kilometers per hour, thereby greatly influencing the exertion of the road transportation capacity and reducing the vehicle transportation efficiency. In addition, overload also causes a large number of traffic accidents, and because of overload, the vehicle control capability is reduced, and the traffic accidents are easy to happen.

In order to control the overload phenomenon of the trucks on the highway, at present, a high-speed dynamic weighing system is arranged on some highways with serious overload phenomenon in China for dynamic weighing detection. In the conventional high-speed dynamic weighing apparatus, a narrow-strip high-speed weighing apparatus is mainly used. Compared with the flat plate type weighing device, the narrow strip type high-speed weighing device has the advantages of sensitive response, good restorability and high measurement precision, so the narrow strip type high-speed weighing device is widely applied.

A common narrow strip-type high-speed weighing device includes a weighing platform, a plurality of load cells mounted below the weighing platform, a vehicle separator, and a data processing unit. After each axle of the vehicle passes through the weighing table board in sequence, the weighing sensor collects weighing signals of the vehicle, the data processing unit processes the weighing signals to further calculate the weight of each axle, and then the weight of the whole vehicle is calculated.

When the narrow strip type high-speed weighing device is installed on site, a shallow trench with the length of about 10cm needs to be chiseled on the road surface along the traveling direction, and the weighing sensor and the weighing table top are buried in the road surface; installing the coil vehicle separator in a road surface with an upper scale or a lower scale direction of the vehicle; the data processing unit is arranged at the road edge, and the weighing sensor and the data processing unit perform data transmission.

The problems that arise after a period of use of the above-described narrow strip-type high-speed weighing apparatus are: 1. the cement/asphalt expansion coefficient at the joint of the weighing table top of the narrow strip type weighing device and the pavement is different, so that cracks are generated at the joint of the weighing table top and the pavement; the truck rolls the crack continuously, so that the road surface is easy to break and even collapse; 2. cracks generated at the joint of the two are often poured backward by rainwater, so that the roadbed of the whole expressway is seriously damaged; the potential safety hazard of driving is easily caused; 3. the weighing precision of the narrow strip type weighing device is influenced, and the measurement is inaccurate; 4. the maintenance cost is high.

SUMMERY OF THE UTILITY MODEL

In view of the above, it is an object of the present invention to provide a packaged narrow strip high speed weighing apparatus. The packaged narrow strip high-speed weighing device can effectively overcome the defect that cracks are generated at the joint of the traditional narrow strip high-speed weighing device and the road surface, keep the road surface of the expressway intact and prolong the service life of the expressway; the weighing precision of the narrow strip type high-speed weighing device is ensured.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a high-speed weighing device of encapsulation formula narrow strip, it includes the high-speed weighing device of narrow strip formula, its characterized in that: it also includes a metal groove; a weighing table top of the narrow strip type high-speed weighing device and a weighing sensor fixed on the back of the weighing table top are placed in the metal groove;

the metal groove is buried in the road surface, and non-telescopic grouting material is filled between the metal groove and the road surface.

Preferably, the height of the metal groove is 100-200 mm, and the wall thickness of the metal groove is 14mm +3 mm.

Detailed Description

The structure and features of the present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that various modifications can be made to the embodiments disclosed herein, and therefore, the embodiments disclosed in the specification should not be construed as limiting the present invention, but merely as exemplifications of embodiments thereof, which are intended to make the features of the present invention obvious.

In order to avoid cracks generated in cement/asphalt at the joint of a weighing table top of the narrow strip type high-speed weighing device and a road surface; as shown in fig. 1 and 2, the utility model adds a metal tank 1, and a weighing table-board 3 with a weighing sensor 2 fixed on the back is placed in the metal tank 1. When the road surface grouting material is installed, a shallow trench is dug on the road surface along the driving direction, the metal groove 1 is buried in the road surface, and then the non-telescopic grouting material 4 is filled between the metal groove 1 and the road surface.

In the embodiment of the present invention, the metal tank 1 is an iron tank, the height of which is 100-200 mm, and the wall thickness of the metal tank is 14mm +3 mm. The non-telescopic grouting material is a product produced by the Jiu-as-road-material-technology company Limited in Henan.

Because the narrow-strip-type high-speed weighing device is packaged in the metal groove, the protective device is added, and the non-telescopic grouting material is filled between the metal groove and the pavement material, the field test proves that no gap is generated between the narrow-strip-type high-speed weighing device and the pavement; the damage to the road surface during the vehicle running is effectively prevented, and the service life of the highway is prolonged; the measuring accuracy and the weighing precision of the narrow strip type high-speed weighing device are ensured. The utility model is suitable for a various road surfaces (cement and pitch), installation condition is unrestricted.

Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
