Description

Technical Field

[0001] This utility model relates to the field of truck scale technology, and in particular to an unattended electronic truck scale. Background Technology

[0002] Traditional vehicle weighing requires manual intervention in weighing and recording, which is not only time-consuming and labor-intensive but also prone to errors and even cheating. However, some companies are developing unmanned truck scales that can automate these tasks, significantly reducing labor and time costs. Because the system employs intelligent management, it minimizes human intervention and avoids economic losses due to improper operation or cheating.

[0003] During long-term use, the weighing platform of electronic truck scales (usually made of steel or concrete) is prone to deformation (such as bending or denting) due to factors such as metal fatigue, foundation settlement, overload impact, and environmental corrosion. After deformation, the load distribution of the pressure sensor array becomes unbalanced, with some sensors overloaded and others underloaded, potentially leading to overall measurement inaccuracies and a decrease in weighing precision. Therefore, this invention provides an unattended electronic truck scale to solve the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to provide an unattended electronic truck scale. Through the modular design of the pre-embedded plate and screw, combined with the double locking structure of the adjusting nut and the positioning nut, the base plate can be quickly installed and leveled with high precision. Moreover, the weighing plate adopts a multi-layer composite design (steel plate layer, FRP composite middle layer, and reinforcing rib layer) and has a pre-set reverse arch to improve the resistance to deformation, so as to reduce the deformation of the weighing platform after long-term use, thereby ensuring the uniformity of the force on the weighing sensor and the measurement accuracy.

[0005] To achieve the above objectives, an unattended electronic truck scale is provided, comprising a base plate and a weighing plate disposed above the base plate, wherein a plurality of weighing sensors are uniformly fixed between the base plate and the weighing plate.

[0006] The weighing plate has a multi-layer composite structure, and the top of the weighing plate is provided with an arc-shaped reverse arch.

[0007] The bottom of the base plate is provided with a plurality of support components, the support components including a pre-embedded plate, a plurality of screws uniformly fixed on the top of the pre-embedded plate, an adjusting nut threaded on the screws and located below the base plate, and a positioning nut threaded on the screws and located above the base plate.

[0008] According to the unattended electronic truck scale, the support assembly further includes a casting block, which is disposed between the embedded plate and the base plate.

[0009] According to the unattended electronic truck scale, the weighing plate includes a steel plate layer, an FRP composite middle layer, and a reinforcing rib layer arranged sequentially from top to bottom.

[0010] According to the unattended electronic truck scale, a plurality of limiting components are evenly provided between the base plate and the weighing plate. The limiting components include a fixed frame fixed to the top of the base plate and a guide rod sliding inside the fixed frame. The top end of the guide rod is fixedly connected to the weighing plate.

[0011] According to the unattended electronic truck scale, the limiting component further includes multiple rollers rotating inside the fixed frame, the rollers forming a square structure and all contacting the outer side of the guide rod.

[0012] According to the unattended electronic truck scale, the guide rod is made of wear-resistant ceramic material, and two positioning nuts are provided on each of the screw rods.

[0013] This utility model has the following beneficial effects:

[0014] 1.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-5 This utility model provides an unattended electronic truck scale, which includes a base plate 1 and a weighing plate 2 disposed above the base plate 1. A plurality of weighing sensors 11 are uniformly fixed between the base plate 1 and the weighing plate 2. The weighing plate 2 has a multi-layer composite structure, and the top of the weighing plate 2 is provided with an arc-shaped reverse arch 15. The weighing plate 2 includes a steel plate layer 12, an FRP composite middle layer 13 and a reinforcing rib layer 14 arranged sequentially from top to bottom.

[0025] Weighing plate 2 adopts a multi-layer composite design, from top to bottom as follows:

[0026] Steel plate layer 12, surface hot-dip galvanized to improve wear resistance;

[0027] FRP composite middle layer 13 uses glass fiber reinforced resin to reduce overall weight and enhance corrosion resistance;

[0028] The reinforcing rib layer 14 adopts a crisscross steel frame, which is welded to prevent deformation under long-term load.

[0029] Meanwhile, the reverse arch 15 set on the top of the weighing plate 2 is preset with a reverse arch to compensate for the expected deformation caused by vehicle rolling, improve the deformation resistance of the truck scale, ensure the uniformity of the force on the weighing sensor 11, and ensure the weighing accuracy.

[0030] The bottom of the base plate 1 is provided with multiple support components. The support components include a pre-embedded plate 3, multiple screws 4 uniformly fixed to the top of the pre-embedded plate 3, an adjusting nut 5 threaded on the screws 4 and located below the base plate 1, a positioning nut 6 threaded on the screws 4 and located above the base plate 1, and a casting block 7. The casting block 7 is located between the pre-embedded plate 3 and the base plate 1.

[0031] The embedded plate 3 is embedded in the foundation by pouring concrete. The base plate 1 is inserted on the outside of the screw rod 4. At the same time, the position of the adjusting nut 5 is adjusted to keep the base plate 1 horizontal. The positioning nut 6 is tightened onto the screw rod 4 to fix the base plate 1 in place. Then, a casting block 7 is poured between the embedded plate 3 and the base plate 1 to form a stable support after curing, while reducing vibration transmission.

[0032] By rotating the adjusting nut 5, the level of the base plate 1 can be adjusted, reducing installation tilt error. In addition, if the foundation settles later, the adjusting nut 5 can be finely adjusted to restore the level without disassembling the scale body, thus ensuring the level of the weighing plate 2.

[0033] Multiple limiting components are evenly provided between the base plate 1 and the weighing plate 2. The limiting components include a fixed frame 8 fixed to the top of the base plate 1, a guide rod 9 sliding inside the fixed frame 8, and multiple rollers 10 rotating inside the fixed frame 8. The top of the guide rod 9 is fixedly connected to the weighing plate 2, and the rollers 10 form a square structure and are all in contact with the outside of the guide rod 9.

[0034] The guide rod 9 moves vertically with the weighing plate 2 and moves between the rollers 10 to eliminate horizontal offset force and improve the stability of the weighing plate 2 when it moves up and down.

[0035] The guide rod 9 is made of wear-resistant ceramic material, specifically zirconia ceramic, to reduce deviations caused by wear. Each screw 4 has two locating nuts 6, with a retaining washer fitted onto the screw 4 below the bottom locating nut 6. This double-nut structure, combined with the retaining washer, significantly improves the anti-loosening effect of the locating nut 6.

[0036] Working principle: The embedded plate 3 is embedded in the foundation by pouring concrete. The base plate 1 is inserted on the outside of the screw rod 4. At the same time, the position of the adjusting nut 5 is adjusted to keep the base plate 1 horizontal. The positioning nut 6 is tightened onto the screw rod 4 to fix the base plate 1 in place. Then, a casting block 7 is poured between the embedded plate 3 and the base plate 1 to form a casting block. After curing, it forms a stable support and reduces vibration transmission.

[0037] By rotating the adjusting nut 5, the level of the base plate 1 can be adjusted, reducing installation tilt error. In addition, if the foundation settles later, the adjusting nut 5 can be finely adjusted to restore the level without disassembling the scale body, thus ensuring the level of the weighing plate 2.

[0038] The weighing plate 2 adopts a multi-layer composite design. From top to bottom, it consists of a steel plate layer 12 with hot-dip galvanized surface treatment to improve wear resistance; an FRP composite middle layer 13 made of glass fiber reinforced resin to reduce overall weight and enhance corrosion resistance; and a reinforcing rib layer 14 with a crisscross steel frame welded together to prevent deformation under long-term load. Simultaneously, a reverse arch 15 is provided at the top of the weighing plate 2, with a pre-set reverse camber to compensate for expected deformation caused by vehicle rolling, improving the scale's resistance to deformation and ensuring uniform force distribution on the weighing sensor 11, thus guaranteeing weighing accuracy.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
