[0002] Dynamic truck scales, also known as floor scales, electronic floor scales, etc., are devices that can weigh vehicles while they are in motion. Dynamic truck scales are widely used in highway toll stations, logistics parks, mines and other places, and play an important role in vehicle weighing management, traffic flow monitoring, and cargo measurement.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-5 The utility model is described in further detail.

[0036] Reference Figure 1The high-precision combined dynamic vehicle scale of this embodiment includes multiple weighing platforms and multiple connecting mechanisms 300 arranged on the ground. In this embodiment, the weighing platforms are all rectangular weighing platforms 3, and the multiple weighing platforms include multiple long weighing platforms 100 and multiple short weighing platforms 200. The long weighing platforms 100 and the short weighing platforms 200 are connected in sequence along the vehicle traveling weighing direction through the connecting mechanism 300 to form a weighing area. Four sensors are arranged in each weighing platform, and the sensors are arranged on the four corners of the weighing platform.

[0037] There are three long weighing platforms 100, which are connected in sequence to form a long weighing platform area. There are two short weighing platforms 200, which are respectively connected to the long weighing platforms 100 on both sides of the long weighing platform area. All the short weighing platforms 200 are connected to the long weighing platforms 100 to form a weighing area. All the weighing platforms are connected through a connecting mechanism 300. The long weighing platform area is mainly beneficial for perfectly solving the problem that the measurement error of the axle or axle group of traditional weighing equipment is large, and it is difficult to distinguish the total weight when following a vehicle. A channel steel frame 600 is provided on the side of the short weighing platform 200 away from the long weighing platform 100. The side of the short weighing platform 200 away from the long weighing platform 100 is detachably connected to the channel steel frame 600 by bolts, and a dust strip is provided on the channel steel frame 600 at the connection position. The number and position of the short weighing platforms 200 and the long weighing platforms 100 can also be adjusted according to actual usage requirements. The combination installation method of three long weighing platforms 100 and two short weighing platforms 200 adopted in this embodiment can not only distinguish traditional truck models but also clearly distinguish more models such as small-wheeled vehicles. Moreover, since the three long weighing platforms 100 are connected to form a long weighing platform 100 area, the dynamic vehicle scale can not only realize the weighing of the whole vehicle, but also realize the direct measurement of the axle or axle group.

[0038] Reference Figure 2 The connection mechanism 300 includes a support plate 310 and two sets of locking components. The support plate 310 is arranged between the weighing platform and the ground to support the entire weighing platform structure. The support plate 310 is located at the connection between the two weighing platforms. The locking components are fixedly arranged on the support plate 310, and the locking components are respectively locked with one weighing platform at the connection. In this embodiment, a connection mechanism 300 is arranged at the connection of the two sides of each set of interconnected weighing platforms. The two sets of locking components connect the two adjacent weighing platforms together, and the entire vehicle scale is supported by all the support plates 310.

[0039] Reference Figure 2 and Figure 3A fixing plate 400 parallel to the support plate 310 is fixedly provided on one side of the weighing platform close to other weighing platforms. In this embodiment, the fixing plate 400 can be welded to the weighing platform or integrally formed. The locking assembly includes a first locking portion 320 and a second locking portion 330. The first locking portion 320 is fixedly connected to the support plate 310 and contacts the side of the fixing plate 400 away from the support plate 310. The second locking portion 330 is fixedly connected to the support plate 310 and contacts the side of the fixing plate 400 close to the support plate 310. The first locking portion 320 and the second locking portion 330 cooperate to clamp the fixing plate 400. At this time, the fixing of the weighing platform is kept fixed by the locking assemblies on both sides of each weighing platform.

[0040] A reinforcement assembly 500 is also provided at the connection between the weighing platforms. The reinforcement assembly 500 includes a reinforcement block 510 and a reinforcement frame 520. The reinforcement frame 520 is fixedly arranged on the support plate 310. One end of the reinforcement block 510 is detachably connected to the reinforcement frame 520, and the other end of the reinforcement block 510 is tightly pressed against the two mutually connected weighing platforms. In this embodiment, since the short weighing platform 200 used is shorter, the reinforcement assembly 500 is only used at the connection between the long weighing platform 100 and the long weighing platform 100. The short weighing platform 200 is set at the position of the weighing platform itself. If the length of the weighing platform allows, it can also be set at the position where the weighing platform is connected to play the role of reinforcing the connection.

[0041] Reference Figure 2-Figure 4 The first locking part 320 includes: a first mounting frame 321 and an upper connecting block 322. The first mounting frame 321 is fixedly arranged on the support plate 310 to play a supporting role. One end of the upper connecting block 322 is detachably connected to the first mounting frame 321 by a bolt. In this embodiment, the upper connecting block 322 can be adjusted in position by a bolt, and the direction of adjusting the position is parallel to the fixed plate 400. The other end of the upper connecting block 322 is pressed against the side of the fixed plate 400 away from the support plate 310. The first locking part 320 also includes an elastic block 323, which is fixedly arranged on the upper connecting block 322. The upper connecting block 322 is pressed against the fixed plate 400 by the elastic block 323.

[0042] A limiting plate 410 perpendicular to the fixing plate 400 is provided on the side of the fixing plate 400 away from the supporting plate 310, and the side of the limiting plate 410 close to the fixing plate 400 is pressed against the upper connecting block 322. A second limiting plate 420 parallel to the limiting plate 410 is also provided on the fixing plate 400, and a limiting opening is provided on the second limiting plate 420, through which the upper connecting block 322 passes, and is pressed against the limiting plate 410, and the elastic block 323 is located at the limiting opening and is pressed against the fixing plate 400. The second limiting plate 420 is used to assist the limiting function of the limiting plate 410, and when the limiting plate 410 is damaged, the second limiting plate 420 will continue to play a limiting role, making the entire structure more stable.

[0043] Reference Figure 3-Figure 5 The second locking portion 330 includes a second mounting frame 331 and a lower connecting block. The second mounting frame 331 is fixedly arranged on the support plate 310. One end of the lower connecting block is detachably connected to the first mounting frame 321. The other end of the lower connecting block is tightly pressed against a side of the fixing plate 400 close to the support plate 310. The upper connecting block 322 and the lower connecting block cooperate to clamp the fixing plate 400.

[0044] Reference Figure 5 , the second locking portion 330 further includes an elastic ball 334, the lower connecting block includes a first lower connecting block 332 and a second lower connecting block 333, one end of the first lower connecting block 332 is detachably connected to the second support frame, the other end of the first lower connecting block 332 is provided with a groove, one end of the second lower connecting block 333 is pressed against the fixing plate 400, the other end of the second lower connecting block 333 is also provided with a groove, and the elastic ball 334 is arranged between the first lower connecting block 332 and the second lower connecting block 333 through the groove. In this embodiment, a protrusion is arranged on one side of the second lower connecting block 333 close to the fixing plate 400, and a groove is arranged on one side of the fixing plate 400 close to the second lower connecting block 333. When the second lower connecting block 333 is pressed against the fixing plate 400, the protrusion is completely stuck in the groove, so that the connection of the second lower connecting block 333 is more stable.

[0045] The implementation principle of this embodiment is: through eight connecting mechanisms 300, two by two are grouped together to connect three long weighing platforms 100 and two short weighing platforms 200, and the connection sequence is "short weighing platform 200-long weighing platform 100-long weighing platform 100-long weighing platform 100-short weighing platform 200". A group of connecting mechanisms 300 is set at each connection, specifically arranged on both sides of each connection along the vehicle travel weighing direction. Four fixing plates 400 are set on each long weighing platform 100, and two fixing plates 400 are set on the short weighing platform 200 on the side close to the long weighing platform 100.

[0046] When making a specific connection, a total of four support plates 310 at both ends of the long weighing platform 100 are placed on the ground, and all the fixing plates 400 are clamped by the first locking part 320 and the second locking part 330 to fix the long weighing platform 100. When installing the weighing platforms on both sides of the other long weighing platform 100, all the fixing plates 400 are clamped by the first locking part 320 and the second locking part 330 to fix the weighing platforms, and bolts are used to reinforce the two adjacent weighing platforms.

[0047] The connection of the short weighing platform 200 is slightly different. One side of the short weighing platform 200 prevents the channel steel frame 600, and the other side prevents two support plates 310. Then, the short weighing platform 200 is fixed by the structures on the channel steel frame 600 and the support plates 310 respectively.

[0048] When weighing, the vehicle enters from the short weighing platform at position 200 on one side, then passes through the long weighing platform at position 100, and exits from the short weighing platform at position 200 on the other side.

[0049] The installation of the weighing platforms is relatively independent, but the weighing platforms are integrated after installation by the setting of the support plate 310. When maintenance is required, the weighing platforms can be disassembled separately and then maintained separately.

[0050] In summary, two short weighing platforms 200 and three long weighing platforms 100 are set up to weigh vehicles from different positions. The vehicle weight can be determined more accurately through comprehensive data, reducing the possible errors of a single weighing platform. Moreover, for vehicles of various lengths and axle numbers, multiple different weighing platforms can better adapt to their passing methods, ensuring the accuracy and reliability of weighing different types of vehicles. The influence of factors such as uneven road surface and unstable vehicle driving state on the measurement of a single weighing platform can be reduced, and the error can be corrected by integrating multiple data. In case a certain weighing platform fails, other weighing platforms can still ensure the continuation of the weighing work to a certain extent, thereby improving the fault tolerance of the entire system and greatly improving the weighing accuracy of the dynamic vehicle scale. At the same time, the setting of the short weighing platform 200 can be well used for weighing small vehicles, and the setting of the long weighing platform 100 can be better used for weighing larger vehicles, which can not only realize the weighing of the entire vehicle, but also realize the direct measurement of the axle or axle group, making the weighing range wider.

[0051] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
