When the double weighing platform structure of the motor truck scale, disclosed by the invention, is used for weighing vehicles, the error can be reduced and the weighing precision can be improved.
Description
Technical field
The invention belongs to for the weighing field in motion process, be specifically related to the two platform structure of weighing of a kind of truck scale.
Background technology
Two weighing platform system is that two weighing platforms are relatively independent, and use software algorithm to be averaged numerical value as last weighing result after repeatedly weighing same vehicle, its precision stability is higher than single weighing platform system.Because counting of gathering of two countertop fixture is many, standby repeated a little higher than single table surface equipment reseted by dual stage face meter.Two weighing platforms backup each other, if weighing platform breaks down, another one weighing platform still can complete independently work, solve the shortcoming of track paralysis when weighing platform fault appears in single weighing platform system.
Control vehicle to evade with fraudulent means toll in, two weighing platform system utilizes the method for repeatedly weighing can effectively prevent vehicle to jump scale and to walk S type mode and carry out evading toll.And the vehicle that the speed of a motor vehicle carries out fee evasion is rushed in utilization, be utilize high speed traveling to slide on weighing platform, to reduce, the collection of weight counted, reach the object reducing weight.Two weighting platform table top is wide, and counting of collection is many, effectively can prevent vehicle and rush the behavior that the speed of a motor vehicle carries out fee evasion.
The algorithm of new weighing platform system is more advanced, greatly reduces the multiaxis of vehicle, few axle, loses axle phenomenon.Weigh more accurate, the different obvious reduction of the meter method of double differences repeating for twice to weigh with vehicle, driver and conductor obviously reduces for the dispute that meter is heavy simultaneously.
Although the structure of two weighing platform can reduce weighting error to a certain extent, improve weighing precision, but because two weighing platform has two weighing platforms, in the process of weighing, if the car speed be weighed is very fast, or when vehicle is unstable, weighing platform there will be the phenomenon of double swerve, and two weighing platforms rock inconsistent, so can produce horizontal force to vehicle in two weighing platforms process of rocking, and horizontal force can affect the vertical by heavy of weighing platform, so still out of true of weighing can be caused.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide one to reduce error, improve the two platform structure of weighing of the precision truck scale of weighing.
For achieving the above object, technical scheme of the present invention is as follows:
The two platform structure of weighing of truck scale, comprise scale body framework, LOAD CELLS, weighing controller, the first weighing platform and the second weighing platform, described first weighing platform and the second weighing platform are arranged side by side on scale body framework, first weighing platform, between the second weighing platform lower surface and scale body framework, be respectively equipped with multiple LOAD CELLS, LOAD CELLS is electrically connected with weighing controller, also be provided with horizontal pull sensor, described horizontal pull sensor connects the first weighing platform and the second weighing platform respectively, and horizontal pull sensor is electrically connected with weighing controller.
When adopting technique scheme, vehicle to be weighed reaches the first weighing platform and the second weighing platform, now the first weighing platform and the second weighing platform pressurized, be positioned at the LOAD CELLS pressurized below the first weighing platform and the second weighing platform, LOAD CELLS is electrically connected with weighing controller, so LOAD CELLS below the first weighing platform and the second weighing platform respectively by signal transmission to weighing controller, thus complete vehicle weighing.Weigh in vehicle processes in the present invention, when the car speed be weighed is very fast, or vehicle is unstable, first weighing platform and the second weighing platform there will be the phenomenon of double swerve, two weighing platforms are rocked the contractility being applied to oneself and are converted to electric signal by the horizontal pull sensor connecting the first weighing platform and the second weighing platform, and by electrical signal transfer to weighing controller, weighing controller according to the size of horizontal pull sensor electrical signal as weight compensating, so just can reduce the error in weighing process, effectively improve weighing precision.
Further, described first weighing platform, be respectively equipped with four LOAD CELLS between the second weighing platform lower surface and scale body framework, four LOAD CELLS are arranged in the position of corresponding weighing platform near turning.Four LOAD CELLS are evenly arranged in below corresponding weighing platform, gather weight data, can obtain the weight of vehicle more accurately by 4.
Further, be provided with two horizontal pull sensors, and two horizontal pull sensors are arranged symmetrically with about the vertical direction of traffic of weighing platform.Two horizontal pull sensors are set, the accuracy of measurement can be improved.
Further, described first weighing platform and the second weighing platform are arranged on scale body framework by multiple U-shaped beam side by side.The mainly channel-section steel of existing use, adopts U-shaped beam compared with channel-section steel, more can save material; And U-shaped beam one-shot forming, no-welding-seam, not easy to crack, so the intensity in use procedure is high; In addition, when adopting U-shaped beam, good at the resonance of dynamic process, improve the accuracy weighed.
Further, polylith stiffening plate is provided with between described U-shaped beam and scale body framework.Stiffening plate can improve the installation strength of U-shaped beam.

Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: scale body framework 1, first weighing platform 2, second weighing platform 3, horizontal pull sensor 4, U-shaped beam 5, stiffening plate 6.
As Fig. 1, shown in Fig. 2 and Fig. 3, the two platform structure of weighing of a kind of truck scale, comprise scale body framework 1, LOAD CELLS, weighing controller, first weighing platform 2 and the second weighing platform 3, first weighing platform 2 and the second weighing platform 3 are arranged side by side on scale body framework 1, first weighing platform 2, four LOAD CELLS are respectively equipped with between second weighing platform 3 lower surface and scale body framework 1, four LOAD CELLS are positioned at below corresponding weighing platform, and the position be evenly arranged near turning, LOAD CELLS is electrically connected with weighing controller, also be provided with horizontal pull sensor 4, horizontal pull sensor 4 connects the first weighing platform 2 and the second weighing platform 3 respectively, and horizontal pull sensor 4 is electrically connected with weighing controller.
