Description

FIELD OF THE INVENTION

This invention relates to a method and apparatus for static weighing of a vehicle (ATS).

State of the art

Several types of devices are known for static weighing of exchanges. The most common include, for example, platform scales (Fig. 1) having a load platform 6 with sensitive elements (sensors) located under it and providing for the placement on the working surface of this platform 10 simultaneously of all wheel axles 1-5 of the vehicle 20 for one-stage determination the total mass of the telephone exchange (for example, a patent of the Russian Federation for utility model No. 133292, publ. 10.10.2013).

To determine the load on the road surface from individual axes of the vehicle, for example, mobile weight control posts (PPVK), the method of static weighing is often used on the basis of a set of portable load-bearing platforms (underframes) placed under the wheels of the vehicle (see, for example, Dr. E. Doupala (Zurich, Switzerland) “Recommendations for accurate weighing with portable (pad) weights” in 2013 issue 7 of the journal Roads.)

With the simultaneous hanging of all wheels of the automatic telephone exchange on a bed scale (see, for example, the description of the EVOCAR 2000 truck scale manufactured by the Finnish company Teknoscale Oy, at http://www.teknoscale.com), it is possible to simultaneously determine (during one measurement cycle) all ATS parameters, standardized by the legislation on weight control: loads of single and close axles, mass (total load) of multi-axle bogies and the total mass of the ATS.

However, in this case, the number of underweight scales corresponding to the largest number of wheels from the entire range of types of controlled automatic telephone exchanges should be provided in the weighing kit. Take, for example, a five-axle dump truck, in this case, to ensure the measurement of its total weight, you need to have a set of ten weights, and, for example, for a six-axle road train, the set of weights must already be supplemented with 12 pieces. But six axles - this is not the maximum with today's diversity of the fleet. And if you are guided by the requirement when measuring the total weight to hang all wheels of the automatic telephone exchange on a bedding scale, then for a nine-axle road train you will need a set of eighteen bedding scales (Fig. 2).

To reduce the number of weights used for weighing, in RF patent No. 2538357 (publ. 10.01.2015), phased weighing of automatic telephone exchanges by groups of axes is proposed. At the first weighing stage (Fig. 3), it is assumed, for example, to place only part of all axles 1-6 of ATS 20 placed on a flat surface 7-13, for example, only axles 1-3 of the tractor; at the second stage, the set of weights 11-13 is shifted to other axes (4-6) of the ATS 20. To align at the time of measurement of all axes of the ATS 20 in one plane, passive shims 14-16 of the same underweight scales.

The disadvantage of this known solution is the low performance of two-stage weighing, associated with the need to rearrange the underweight and, accordingly, the automatic telephone exchange itself.

Disclosure of invention

Thus, there is a need to develop such a method of static weighing of vehicles and devices for its implementation, which would provide the possibility of a one-step measurement of all weight parameters of the vehicle.

To solve this problem with achieving the specified result, the first object of the present invention proposes a method of static weighing of a vehicle (ATS), which consists in the following: set the ATS with the wheels of all its axles on a platform scale; place on the platform scales the underlay scales under all the wheels of each axle from the selected set of one or more axes of the ATS; at the same time measure the total load of all the axes of the ATS platform scales and the corresponding loads attributable to each of the underlay scales; determine the load from the selected set of axles by summing the loads of all the weights; determine the total load from the remaining axes of the ATS as the difference between the total load of all its axes, measured by platform scales, and the sum of the loads measured by the underweight scales.

A feature of the method of the present invention is that as a set of selected axes take one or more axes that are not part of the largest number of axles of a multi-axle ATC cart.

In this case, the total load of the largest number of axles of the multi-axle bogie of the ATS can be determined by subtracting from the total load of all the axes of the ATS, measured by platform weights, the sum of the axial loads measured by all the underlay weights.

To solve the same problem with achieving the same result, in a second aspect of the present invention, there is provided a device for static weighing of a motor vehicle (ATS), comprising: platform scales designed to mount ATS on them with wheels of all its axes; a set of underfloor scales, each of which is designed to be placed on a platform scale under all wheels of each axle from a selected set of one or more axes of the vehicle; computing means configured to receive indications of platform weights and weights and determine the load from the selected set of axes by summing the readings of all the weights and determine the total load from the remaining axes of the ATS as the difference between the readings of the platform weights and the sum of the readings of the weights.

A feature of the device according to the present utility model is that one or more axes that are not part of the largest number of axles of a multi-axle ATC trolley are taken as a set of selected axes.

In this case, the computing means can be configured to determine the total load of the largest number of axles of the multi-axle ATC carriage by subtracting from the total load of all the axes of the ATC measured by platform weights, the sum of the axial loads measured by all supporting weights.

DETAILED DESCRIPTION OF THE INVENTION

In the present invention, the combination of weighing the entire ATE on a platform scale and weighing part of the axes of this ATE on a bed scale is carried out.

The present invention is illustrated in FIG. 4. The motor vehicle 20 (in this case, six-axle) is installed with all its axles 1-6 on the platform scales 10, placed on a flat surface 7. In addition, under the wheels of the first three (in the direction of movement of the ATS 20) axes 1-3, there are lining scales 11-13 respectively. To align the ATC under the wheels of the other axes 4-6, passive platforms 14-16 of the same height are placed as the used weighing scales 11-13. As platform and underlay scales, you can use both the models already described above, and any other, existing or developed in the future.

In FIG. 4 does not show computing means that can receive readings of both platform weights 10 and weights 11-13. The main thing is that such a computing tool can determine the load from the selected set of axles by summing the readings of all used weights 11-13 and determine the total load from the remaining axes (4-6 in Fig. 4) of the ATS 20 as the difference between the readings of the platform weights 10 and the sum of the readings weights 11-13. This computing tool can be selected from the group including a personal computer, tablet, laptop, server. In principle, any computing tool that allows you to determine the axle load, the mass of the multi-axle trolley, the total mass of the automatic telephone exchange as a whole according to the results of weighings from platform and underlay scales is suitable. These results can be transmitted to such computing means via wired or wireless communication lines, while the computing means, of course, is configured to receive weighting results on the corresponding communication lines.

The device of the present invention works like this.

The weighed ATS 20 is installed on the load-receiving platform of the platform scales 10 with all its axles (all of their wheels are single or gable). Let it be, for example, a six-axle road train, as shown in FIG. 4, then on the platform scales 10 the wheels of all axles 1-6 of this ATS 20 will be placed. In this case, a set of three pairs of underlay scales 11-13 is placed under the three axles 1-3 of the tractor, ensuring that they determine the load of the front axle 1 and the total load (mass) of axles 2 and 3 of its rear bogie.

Thus, the total weight of the ATC 20 will be measured by the platform scales 10. The undersized scales 11-13 (according to Fig. 4) will measure the load from the front axle 1 and two axes 2-3 of the rear truck. The measured data on the corresponding communication lines will go to a computing tool that will determine the total mass of the ATS 20, the weight (load from) of the tractor (axles 1-3) and the total load (mass) of the three-axle bogie (axis 4-6) of the semitrailer by subtracting the sum of the front load axis 1 and a biaxial rear bogie (axles 2, 3) of the tractor from the total mass of the vehicle.

Those skilled in the art will appreciate that fewer weights can be used in the present invention than the total number of wheels of a weighted vehicle. It should be specially noted that in this text a wheel, as noted earlier, is understood to mean both a single-wheel wheel and a double-wheel wheel, of course, if the size of the load-receiving platform allows the installation of a gable wheel on it. The number of axles in their selected combination can be from one to (in principle) N-1, where N is the total number of axles of the vehicle exchange system 20. That is, for example, for class 3 of the European classification of vehicles GRCS-03 / EUR 13, into which three-axle trucks with a biaxial rear bogie (Fig. 5a), in the selected set of axles there will be only one front axle, while for a road train in class 8, more precisely, for its most common modification as part of a two-axle tractor unit and a biaxial semi-trailer (Fig. 5b ), in the selected set of axes tsya, for example, both the tractor axis. In the example of FIG. 4, it is obvious that three front axles 1-3 belong to the selected set of axles.

Thus, the present invention provides the possibility of a one-step measurement of all weight parameters of the exchange.
