The measurement detecting unit 200 is an essential component for checking the weight of the load in real time, and the means is preferably a load cell.

This load cell is a kind of load sensor that recognizes the weight change due to tension in mV unit and converts it into weight again, and when it receives weight, it is deformed or compressed. By converting into a digital signal it is expressed as a number. That is, it can be composed of an elastic material attached to a strain gauge that converts the load due to external force into an electrical signal. When the mass is applied, the material behaves elastically, and the strain gauge directly changes the resistance corresponding to the applied mass. It is operated as an electrical device that changes the load change into a change in resistance, resulting in four strain gages, and the four arms can be wired with the Wheatstone Bridge. In addition, the most important factor that determines the performance of such a load cell is the structure of the elastic deformation body, which is determined by the load characteristics, capacity, and precision to be measured, and thus the elastic deformation body is attached to the strain gauge in response to the applied load. It should be possible to generate a uniform strain intensively.

In installing the weighing assembly of the present invention in a trailer as shown in FIG. 7, a measurement detecting unit 200 is installed between a chassis that connects and fixes the front and rear axles of the vehicle integrally, or a reinforcement chassis that is fixedly opposed to the chassis on the bottom of the loading box. ) Is placed inside the fixed housing 300, the bottom of the trailer loading box 500 is fixed to the top plate 110 of the weight transfer unit 100 is fixedly arranged or a separate shoring 550 as shown in the drawing After being interposed, the upper plate 110 may be placed in close contact with the support below to sense the weight of the loading box.

In this case, it is preferable that a plurality of load cells, which are the measurement detecting unit 200, are arranged at equal intervals for more accurate measurement. Bar, the process of measuring the weight by the load cell is as follows.

First, by removing the inlet member 350 for the measurement of the weight of the assembly that was in the initial state as shown in Figure 5, the weight transfer unit 100 that is restrained in the designated position is free, the top plate 110 of the weight transfer unit The weight transfer unit 100 is downward while the load of the load is gradually given through the bottom, and the contact unit 121 of the extension frame 120 is connected to the head 220 of the measurement sensing unit 200 by such a position change. As the pressure is gradually pressed to the measurement detecting unit 200, the physical quantity of the force is converted into an electrical signal and displayed on the monitor of the driver's seat through a cable.

[Example 2]

FIG. 10 is a cross-sectional configuration diagram of a weighing assembly constructed by another embodiment of the present invention, and FIG. 8 shows a state diagram of use of the mobile weighing assembly according to FIG. 10.

As shown in the figure, it may be provided in a different form from the first embodiment.

That is, by further forming a fixed bracket 400 equipped with a bearing 410 on the weight transfer unit upper plate 110 provided in a plate shape so that it can be mounted on a conventional dump truck as shown in FIG. Is the same as Example 1. However, due to the characteristics of the dump truck to be flipped to the rear by the driving of the cylinder 600 to drop the load, it was fixed to the lower side of the cylinder and the lower side (dump hinge) of the rear end of the loading box, Specifically, the lower end of the cylinder is placed in a pair of fixed bracket 140 bearings 410, while the rear end of the loading box and the lower side (dump hinge) thereof are also introduced into the bearing 410 of the fixed bracket, thereby By being able to cope with the change of position, the desired purpose is achieved.

That is, when the cylinder rod is developed by using the hydraulic pressure of the vehicle for carrying out the load, the position of the cylinder 600 itself varies according to the height change of the loading box, and the position change of the cylinder can be properly compensated. The fixed bracket 400 equipped with the bearing 410 is provided in the weighing assembly of the present invention so that the cylinder can be accurately driven even if the cylinder is driven up and down within a certain range to raise or lower the loading box. Will be performed.

[Example 3]

Although not shown in the drawings, the measurement sensing unit 200 and the extension frame 120 may be configured differently. For example, not only the upper end of the measurement sensing unit to be in a triangular shape, but also the inner space of the extension frame to be hollow is also produced in a corresponding shape to achieve the desired purpose.

The object is deformed in proportion to the force or load, and the deformation rate per unit length is linearly changed by the magnitude of the force or load. The measurement of the above strain is required, and the measuring device for this is a strain gauge, which uses a strain gauge that is proportional to the material length of the resistance occurring in the material and is inversely proportional to the cross-sectional area. The resistance change rate of the gauge is converted into a value of the voltage change amount. The voltage variation detected using the operation principle of the load cell is amplified by the output of the detection circuit and displayed on the display unit.

In addition, in general, the freight vehicle may include a "0" point adjustment switch for setting the tolerance state without loading the package because the weight of the freight vehicle is changed depending on whether or not the amount of fuel or the driver riding the vehicle from time to time. Therefore, it is possible to detect the weight of only the package to be loaded by loading the package after the adjustment of the "zero point" in the tolerance state, it is possible to load the package suitable for the carrying capacity of the truck. In particular, by installing a plurality of load cells for detecting the weight on the lower side of the loading box, the weight of the package is detected by calculating the dump hinge of the loading box and the load distributed to the load cell. At this time, the weight of the loading box is calculated in consideration of the weight set at the time of manufacture.It is preferable to program a calculation formula in advance to input the two triangular hinge loads and the positional triangular divided load of the load cell added to the rear end of the loading box. Do. Accordingly, when the switch is operated while the loading box is empty, “0” is displayed on the display unit, and the weight is displayed when the package is loaded in the loading box.

The present invention is equipped with a number of separate measuring device (load cell) for weighing at the bottom of the loading box to immediately display the measured weight from the driver's seat, so that the weight of the load can be understood by itself, thereby opening the place It is a load weighing assembly of a freight vehicle that thoroughly eliminates the hassle that had to come and go until it is possible to quickly weigh the cargo as needed.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it should be clear to those skilled in the art that various modifications and equivalent other embodiments are possible therefrom. will be. Therefore, the true technical protection scope of the present invention should be interpreted by the appended claims, and all technical ideas within the equivalent scope should be construed as being included in the scope of the present invention.
