Description

Complete weighing narrow strip type high-speed weighing device

Technical Field

The utility model relates to a narrow strip type high-speed weighing device, in particular to a narrow strip type high-speed weighing device which can really realize complete weighing.

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 high-speed weighing device, the narrow-strip type high-speed weighing device has the advantages of quick deformation recovery of the weighing table surface, good recovery, sensitive response and high measurement precision, so that the narrow-strip type high-speed weighing device is widely applied.

At present, a narrow strip type high-speed weighing device laid on a highway comprises a weighing table top, a plurality of weighing sensors arranged below the weighing table top, a vehicle separator and a data processing unit. The weighing sensor and the weighing table-board are buried in the road surface; the vehicle separator is arranged in a road surface in the direction of the upper scale or the lower scale 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 in a wired mode or a wireless mode. 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.

The narrow strip type high-speed weighing device has the following defects: because the length of a weighing table top of the conventional narrow-strip high-speed weighing device is only about 100mm (the width of the weighing table top is consistent with the width of a lane), the contact area between a tire and the weighing table top is too small, one part of the tire is pressed on the weighing table top, and one part of the tire is pressed on the road surface to support the road surface, the conventional narrow-strip high-speed weighing device is incomplete weighing, and does not belong to effective complete weighing, a data processing unit is also required to perform weight compensation calculation, the calculation accuracy determines the weighing accuracy, particularly for abnormally running vehicles or modified irregular vehicles, the weighing accuracy confidence coefficient is not high, and the accurate weighing of the vehicles in the free running process cannot be realized.

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.

The weighing table-board of the narrow-strip high-speed weighing device is faster in deformation recovery, good in restorability, sensitive in reaction and high in measurement precision than that of the flat-plate high-speed weighing device, so that the narrow-strip high-speed weighing device is widely applied. In order to realize weighing completely, overcome the drawback that current narrow strip formula high-speed weighing device is incompletely weighed, the utility model discloses the length of the high-speed weighing device mesa of weighing of narrow strip formula has been prolonged, but, can not infinitely prolong its length again, still need make the high-speed weighing device of narrow strip formula keep its mesa of weighing to warp and resume advantage rapidly, that sensitivity is high, as shown in fig. 1, the utility model discloses 1 length extension of the mesa of weighing of the high-speed weighing device of narrow strip formula is 150mm-300mm to L, makes the length of its mesa of weighing between the high-speed weighing device mesa length of weighing of narrow strip formula and the flat weighing device of weighing of present incomplete weighing.

Constitute the utility model discloses a mesa 1 of weighing can be a complete mesa of weighing, also can be as shown in fig. 2, the utility model discloses mesa 1 of weighing is formed by two piece at least

little mesas

11 and 12 concatenations of weighing that set up side by side, the total width of mesa 1 of weighing equals the width in a lane. The effective area of each small weighing table-board is less than or equal to that of the weighing table-board of the narrow-strip high-speed weighing device. Its purpose makes to constitute the utility model discloses a mesa 1 of weighing still has the deformation and resumes advantage fast, that recovery nature is good, sensitivity is high.

Because the utility model discloses prolonged the length of the high-speed weighing device mesa of narrow strip formula of weighing, as shown in fig. 3, make it can hold at least one axletree 2 and press on the mesa 1 of weighing, prolonged the effective time of vehicle through the mesa of weighing, make the data processing unit of the high-speed weighing device of narrow strip formula can directly read the every axle load capacity of freight train, and needn't carry out weight compensation and calculate, realize really weighing completely, the weighing result is more accurate.

In order to ensure the measuring precision of the utility model, as shown in fig. 1-3, the back of the weighing table-board of the utility model is at least provided with 2 weighing sensors 3 so as to accurately measure the weight of each tire on each shaft.
