Detailed Description

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Meanwhile, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; the connection can be mechanical connection or electrical connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The following describes preferred embodiments of the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1 to 2, an electronic truck scale includes a weighing platform 1, a mounting cavity 2, a nitrogen spring 3, a nitrogen spring positive top block 4 and a sensor pressure head 5; weighing platform 1 is the square body structure, and its upper surface is on a parallel with the horizontal plane to the upper surface has certain roughness, can not slide when weighing in order to guarantee the transport vechicle that carries cargo, weighing platform 1 is equipped with five installation cavity 2, five installation cavity 2 is established respectively four turnings and the intermediate position of weighing platform 1. The piston rod of the nitrogen spring 3 is connected to the inside of the installation cavity 2 through the nitrogen spring positive ejection block 4, and the sensor pressure head 5 is arranged below the cylinder of the nitrogen spring 3. The nitrogen spring 3 assembly product is a novel elastic functional component, is an upgrading and updating product of a conventional spiral spring, and the nitrogen spring 3 is a component with an elastic function. The high-pressure nitrogen is sealed in a determined container, the nitrogen is compressed by external force through a piston rod, and certain elastic pressure is obtained by the expansion of the high-pressure nitrogen when the external force is removed, and the component is called a nitrogen cylinder or a gas spring, and is called a nitrogen spring 3 for short. Compared with the traditional spiral spring, the nitrogen spring 3 has the characteristics of small volume, large elasticity, long service life, difficult rusting, constant elastic pressure and the like.

As shown in fig. 2, in this embodiment, at least three U-shaped beams 6 are further installed on the lower surface of the weighing platform 1, so that various performance indexes such as rigidity, torsion resistance, pressure resistance and the like of the whole scale body are greatly improved. Weighing platform 1 sets up two crossbeams 7, crossbeam 7 with U type roof beam 6 is perpendicular, the both ends of crossbeam 7 are fixed on the positive kicking block 4 of nitrogen spring, because U type roof beam 6 is parallel setting is in weighing platform 1's lower surface, all do not have any contact between the U type roof beam 6, cause a certain U type roof beam 6 very easily great heavy, not only can cause weighing inaccurate, also can collapse U type roof beam 6 by the inhomogeneous stress moreover, weighing platform sets up two crossbeams 7 and has guaranteed that the atress between the U type roof beam 6 is even.

In this embodiment, further, be equipped with the stopper on the weighing platform 1 to prevent to exceed the bearing limit damage spring of spring, because the freight transportation car is all with ton as the unit, hardly estimate a weight, if the freight transportation car goes on the weighing platform, in case the weight of freight transportation car exceeds the limit of the spring of nitrogen gas, will bring irreversible damage for nitrogen gas spring 3.

In this embodiment, a computer is further installed on one side of the electronic truck scale, the computer is connected to the sensor ram 5, the cargo truck is a relatively large object, when the cargo truck travels to the weighing platform 1, the weight data transmitted from the sensor is determined to be different, and in order to maximally approach the actual mass of the cargo truck, the computer program can be used to automatically receive the data and calculate the average value.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
