[0031] See also Figures 1 to 3 The utility model provides a truck scale 100, comprising:

[0032] a plurality of dowel pin assemblies;

[0033] The weighing platform assembly 1 includes a plurality of platforms 11, each platform 11 is formed with a connecting block 111, each connecting block 111 is formed with a mounting position 111a, and a positioning pin assembly sequentially passes through two mounting positions 111a to connect two adjacent platforms 11;

[0034] The induction component 2 is used to be installed on the base plate 101, and the induction component 2 is connected to the weighing platform component 1. Specifically, the operator installs the induction component 2 on the base plate 101, and then connects multiple platforms 11 in sequence according to the longest length of the vehicle 102 to be weighed. When connecting, the positioning pin assembly is passed through the two installation positions 111a to connect the two adjacent platforms 11 to each other, and then the connected weighing platform component 1 is connected to the induction component 2, so that the installation of the vehicle scale 100 is completed. The vehicle 102 to be weighed is moved to the middle position of the weighing platform component 1, and then the weight of the vehicle 102 will be transferred from the weighing platform component 1 to the induction component 2, and the induction component 2 will obtain the weight, thus completing the weighing of the vehicle 102; when the weighing platform component 1 is damaged due to a long period of time When the weighing scale is damaged, the operator can replace only the damaged platform 11 according to the location of the damage. First, remove the positioning pin assembly from the two installation positions 111a, then remove the damaged platform 11, place the new platform 11 at the original position of the damaged platform 11, and then pass the positioning pin assembly through the installation position 111a of the new platform 11 and the installation position 111a of the adjacent platform 11 in sequence, so that the new platform 11 is connected and fixed; through such an arrangement, when the weighing platform assembly 1 is damaged and needs maintenance, only the platform 11 at the damaged position needs to be replaced, which greatly reduces the maintenance cost of the vehicle scale 100.

[0035] See also Figures 1 to 3 In one embodiment, the connecting block 111 includes a plurality of connecting sub-blocks 111b, the mounting position 111a includes a plurality of mounting holes 111c, the number of the plurality of mounting holes 111c is equal to the number of the plurality of connecting sub-blocks 111b, and one mounting hole 111c is arranged on one connecting sub-block 111b, and the plurality of connecting sub-blocks 111b are arranged in a rectangular shape; the positioning pin assembly includes a plurality of positioning pins 3, the number of the plurality of positioning pins 3 is equal to the number of the plurality of connecting sub-blocks 111b, the connecting sub-block 111b of one connecting block 111 abuts against the connecting sub-block 111b of another connecting block 111, and a positioning pin 3 passes through two mounting holes 111c to connect two adjacent platforms 11. Specifically, since the connecting sub-block 111b is arranged in a rectangular shape, when connecting two adjacent platforms 11 to each other, it is necessary to make the two connecting sub-blocks 111b on the opposite sides of the two platforms 11 abut each other up and down, and then pass the two positioning pins 3 through the two mounting holes 111c respectively, so that the two adjacent platforms 11 are connected to each other; by arranging multiple connecting sub-blocks 111b in a rectangular shape, the weight borne by the platform 11 can be made more uniform during weighing, thereby reducing the possibility of damage to the platform 11; further, the two platforms 11 are connected by multiple positioning pins 3, which greatly improves the connection strength between the two platforms 11.

[0036] See also Figures 2 to 4In one embodiment, the sensing assembly 2 includes a plurality of sensors 21, which are distributed in a rectangular shape and are used to be installed on the base plate 101, and the plurality of sensors 21 are connected to the weighing platform assembly 1. The plurality of sensors 21 are distributed in a rectangular shape, so that when weighing, when the vehicle 102 drives onto the weighing platform assembly 1, the weight of the vehicle 102 will be evenly transferred to each sensor 21, which can improve the detection accuracy of the sensor 21.

[0037] See also Figures 1 to 3 In one embodiment, the truck scale 100 further includes a display screen 4, a junction box, a cable 5 and a bus 6. One end of the cable 5 is connected to the junction box, the other end of the cable 5 is connected to a sensor 21, the first end of the bus 6 is connected to the junction box, and the second end of the bus 6 is connected to the display screen 4. There are multiple cables 5, and the number of the multiple cables 5 is equal to the number of the multiple sensors 21, and they are arranged in a one-to-one correspondence. Specifically, the signals are aggregated through the multiple cables 5 and the wiring terminals of the multiple sensors 21 and the junction box, and then the bus 6 is respectively connected to the junction box and the display screen 4, so that the signal is transmitted to the display screen 4, so that the weight measured by the sensor 21 can be displayed on the display screen 4, so that during the weighing operation, the operator can observe the specific value on the display screen 4, which is convenient for the operator to record.

[0038] In one embodiment, the accuracy level of the sensor 21 is C6. The accuracy level of the sensor 21 used in the conventional truck scale 100 is C3, and the maximum division number of the sensor 21 is nLC≤3000, so the maximum verification division number n≤3000 of the electronic truck scale 100; in this embodiment, a high-precision sensor 21 with an accuracy level of C6 is used, the maximum division number of the sensor 21 is nLC≤6000, and the minimum verification division value Vmin=Emax / 20000, and the verification division value can be smaller, so that the data can be more accurate.

[0039] Furthermore, the accuracy level of the sensor 21 is not limited to C6, but can also be higher C7, C8, C9 or C10, etc., so that the vehicle scale 100 can have higher accuracy.

[0040] In one embodiment, the calibration division number of the truck scale 100 is less than or equal to 6000. Because the calibration division number nLC of the sensor 21 is ≤6000, and the calibration division number nind of the display 4 is ≤6000, the calibration division number n of the truck scale 100 can reach 6000 according to the national standard, and the measurement error of the truck scale 100 is smaller and the measurement accuracy is higher. The accuracy of the truck scale 100 can reach 6000 by improving the rigidity of the weighing platform assembly 1, using high-precision sensors, high-precision displays, and improving the strength of the connection to improve the accuracy of the truck scale 100.

[0041] See See Figure 5 In one embodiment, the platform 11 includes a panel 112 and a plurality of reinforcing members 113 spaced apart along the length direction of the panel 112, and the reinforcing members 113 include a plurality of supporting beams 113a spaced apart along the width direction of the panel 112. Specifically, by providing the supporting beams 113a, the platform 11 can bear a heavier weight, further preventing the platform 11 from being damaged.

[0042] See See Figure 5 In one embodiment, the reinforcement assembly further includes a plurality of reinforcement ribs 113b, and the two ends of each reinforcement rib 113b are respectively connected to two adjacent support beams 113a. Specifically, the reinforcement ribs 113b are welded between two adjacent support beams 113a, so that the deformation of the platform 11 in the width direction is smaller. When the car is on the scale, the deformation of the platform 11 in the length and width directions is reduced, the vertical force on the sensor 21 is greater, and the component force is smaller, thereby reducing the influence of the scale platform factor on the measurement accuracy.

[0043] In one embodiment, the height of the support beam 113a is less than or equal to 400 mm. The support beam 113a is a U-shaped beam, and the bending height of the U-shaped beam reaches 400 mm, so that the rigidity of the platform 11 is better than 1 / 1000, and the overall rigidity, strength and stability of the platform 11 are greatly improved.

[0044] In one embodiment, the vehicle scale 100 further includes an alarm, which is signal-connected to the sensing component 2. By setting the alarm, when the weighed weight is too large, an alarm will be sounded to remind the operator that the vehicle 102 is overweight, so that the overweight part can be removed to keep the weight within a normal range.

[0045] Furthermore, the alarm function can be integrated into the sensing component 2, for example, by using digital technology to achieve self-compensation of parameters such as nonlinearity and temperature performance of the sensor 21, which can make the stability higher; at the same time, the sensor 21 has dynamic encryption, shell damage detection and alarm functions, which makes the anti-cheating ability stronger.
