Description

Technical Field

[0001] This utility model relates to the field of weighing technology, specifically to a sealing structure for the bearing platform of a fully sealed truck scale. Background Technology

[0002] A weighbridge, also known as a truck scale, is a large scale set on the ground. It is usually used to weigh the tonnage of trucks and is the main weighing equipment used by factories, mines, and businesses for measuring bulk goods.

[0003] Traditional truck scales mostly rely on a single rubber sealing strip attached to the gap between the platform and the fixed frame for sealing. However, the sealing strip is prone to aging and cracking due to long-term exposure to vehicle vibration. Rainwater and dust can seep into the installation cavity through the gaps, causing the weighing sensor to become damp and short-circuited or to be covered by dust, affecting weighing accuracy or even causing damage. Therefore, a fully sealed truck scale platform sealing structure is proposed to solve the problems mentioned above. Utility Model Content

[0004] To solve the above-mentioned technical problems, a fully sealed platform sealing structure for truck scales is provided. This technical solution solves the problem mentioned in the background art that the traditional platform sealing structure of truck scales mostly relies on a single layer of rubber sealing strip attached to the gap between the platform and the fixed frame for sealing. The sealing strip is prone to aging and cracking due to long-term impact from vehicle rolling and vibration. Rainwater and dust can seep into the installation cavity through the gaps, causing the weighing sensor to become damp and short-circuited or to be covered by dust, affecting the weighing accuracy or even causing damage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A sealing structure for the platform of a fully sealed truck scale includes a fixed frame. An installation cavity is formed on the inner side of the fixed frame. A first sealing groove is formed on the upper end of the fixed frame outside the installation cavity. Multiple evenly distributed support seats are fixedly connected to the bottom inner side of the installation cavity. A load cell is installed on the upper end of each support seat. A platform body is fixedly connected to the upper end of the load cell. A first sealing strip is embedded inside the first sealing groove. A corner protection plate is installed on the upper end of the first sealing strip. Multiple evenly distributed first connecting screw holes are formed on the upper end of the fixed frame. Multiple evenly distributed second connecting screw holes are formed through the upper end of the corner protection plate. A second sealing groove is formed between the platform body, the first sealing strip, and the corner protection plate. A second sealing strip is embedded inside the second sealing groove.

[0006] Preferably, the upper end of the first sealing strip abuts against the inner top of the corner protection pressure plate and the lower end of the second sealing strip, and the inner side of the first sealing strip abuts against the outer side of the support platform body.

[0007] Preferably, the upper end of the second sealing strip is provided with a V-shaped guide groove.

[0008] Preferably, a V-shaped discharge groove is provided at the upper end of the corner protection pressure plate at the corresponding position of the V-shaped guide groove.

[0009] Preferably, the first and second connecting screw holes are internally threaded with fastening bolts.

[0010] Preferably, the upper end of the second sealing strip is flush with the upper end of the corner protection pressure plate and the main body of the support platform.

[0011] The advantages of this utility model compared with the prior art are: This solution proposes a fully sealed platform sealing structure for a truck scale. The second sealing strip can block most impurities, and the first sealing strip forms redundant protection. Even if a single sealing strip ages, the sealing effect can still be maintained. The corner protection pressure plate covers the corner area, which can resist impact and collision, and reduce the damage rate of the sealing strip at the corner. At the same time, the continuous pressure of the pressure plate on the sealing strip can ensure long-term sealing and adhesion. The synergistic effect of the V-shaped guide groove and the discharge groove can guide rainwater to drain quickly, reduce the soaking time of rainwater on the sealing strip, and prevent the sealing strip from aging faster due to water accumulation.

[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0015] Reference Figures 1-6 As shown, a fully sealed truck scale platform sealing structure includes a fixed frame 1, an installation cavity 2 on the inner side of the fixed frame 1, a first sealing groove 3 on the outer side of the upper end of the fixed frame 1 located outside the installation cavity 2, a plurality of evenly distributed support seats 4 fixedly connected to the bottom inner side of the installation cavity 2, a weighing sensor 5 on the upper end of the support seat 4, a platform body 6 fixedly connected to the upper end of the weighing sensor 5, a first sealing strip 7 embedded inside the first sealing groove 3, a corner protection pressure plate 8 on the upper end of the first sealing strip 7, a plurality of evenly distributed first connecting screw holes 9 on the upper end of the fixed frame 1, a plurality of evenly distributed second connecting screw holes 10 penetrating through the upper end of the corner protection pressure plate 8, a second sealing groove 12 formed between the platform body 6, the first sealing strip 7 and the corner protection pressure plate 8, and a second sealing strip 13 embedded inside the second sealing groove 12.

[0016] Furthermore, the main body 6 of the support platform is used to directly support passing vehicles and transmit the vehicle weight to the weighing sensor 5. The weighing sensor 5 is used to convert the vehicle weight transmitted by the main body 6 of the support platform into an electrical signal to provide weighing data for the truck scale. Multiple support seats 4 are evenly distributed along the bottom of the inner side of the mounting cavity 2 to provide stable support for the weighing sensor 5, disperse the weight of the support platform and the impact force of the vehicle borne by the weighing sensor 5, and avoid damage to the weighing sensor 5 due to excessive local stress.

[0017] Furthermore, the upper end of the first sealing strip 7 abuts against the inner top of the corner protection pressure plate 8 and the lower end of the second sealing strip 13, and the inner side of the first sealing strip 7 abuts against the outer side of the support platform body 6.

[0018] Furthermore, a V-shaped guide groove 14 is provided at the upper end of the second sealing strip 13.

[0019] Furthermore, the second sealing strip 13 is an elastic rubber strip. As the first layer of seal, it can block most solid debris and liquid from entering the second layer of seal through the gap between the main body 6 of the support platform and the corner protection pressure plate 8. At the same time, the surface water is guided to the sides through the V-shaped guide groove 14 at the upper end. The elastic material can adapt to the deformation of the main body 6 of the support platform and, together with the first sealing strip 7, forms a double protection, improving the overall sealing effect.

[0020] Furthermore, the first sealing strip 7 is also an elastic rubber strip, serving as a second layer of seal. It can prevent a small amount of liquid seeping from the first layer of seal from entering the installation cavity 2. The elastic material can adapt to the slight deformation of the support platform body 6 when it is weighed, thus avoiding damage to the sealing strip. The second sealing groove 12 is an annular groove, formed by the outer edge of the support platform body 6, the upper end face of the first sealing strip 7, and the inner side wall of the corner protection pressure plate 8. It provides a fitting and positioning space for the second sealing strip 13. The groove width and groove depth are adapted to the size of the second sealing strip 13. Through the enclosure of the support platform body 6, the first sealing strip 7, and the corner protection pressure plate 8, it is ensured that the second sealing strip 13 does not shift after installation.

[0021] Furthermore, a V-shaped discharge groove 15 is provided at the upper end of the corner protection pressure plate 8 and at the corresponding position of the V-shaped guide groove 14.

[0022] Furthermore, the V-shaped guide channel 14 is used to collect the water accumulated on the upper surface of the support platform body 6 and the corner protection pressure plate 8 into the channel. Through the guiding effect of the V-shaped structure, the water is guided to the V-shaped discharge channel 15 for discharge, thus preventing water from lingering on the sealing surface. Furthermore, the first connecting screw hole 9 and the second connecting screw hole 10 are internally threaded with fastening bolts 11.

[0023] Furthermore, the upper end of the second sealing strip 13 is flush with the upper end of the corner protection pressure plate 8 and the main body of the support platform 6.

[0024] Furthermore, the first connecting screw hole 9 provides a threaded connection point for the fastening bolt 11, and the second connecting screw hole 10 provides a passage for the fastening bolt 11. After passing one end of the fastening bolt 11 through the second connecting screw hole 10 on the corner protection pressure plate 8, it is threadedly connected to the first connecting screw hole 9 of the fixed frame 1, which can realize the fixation of the corner protection pressure plate 8 and the fixed frame 1. The corner protection pressure plate 8 is used to protect the corners of the first sealing strip 7 and the second sealing strip 13, and prevent the sealing strips from being damaged by vehicle vibration and scratches. By tightening the fastening bolt 11, pressure is applied to the corner protection pressure plate 8, so that the corner protection pressure plate 8 squeezes the first sealing strip 7, which can ensure that the sealing strip fits tightly and achieves a seal.

[0025] Working principle: When a vehicle drives onto the platform body 6, the platform body 6 deforms slightly downwards under the influence of gravity. The weighing sensor 5 detects the weight in real time and converts it into an electrical signal to provide data support for weighing. At this time, the first sealing strip 7 and the second sealing strip 13 deform synchronously due to the elastic material properties, always closely adhering to the contact surface between the outer edge of the platform body 6 and the fixed frame 1 and the corner protection pressure plate 8, preventing rainwater or road dust from entering the installation cavity 2 through the gaps. Even if a small amount of rainwater splashes onto the sealing surface, the inner contact surface of the second sealing strip 13 can also prevent rainwater from seeping in, forming the first layer of protection. Any remaining trace amounts of rainwater will be further blocked by the first sealing strip 7, achieving double sealing protection. During rainy weather, rainwater on the upper surface of the support platform body 6 and the corner protection pressure plate 8 flows to the V-shaped guide groove 14 of the second sealing strip 13. The collected rainwater flows along the V-shaped guide groove 14 to the V-shaped discharge groove 15 of the corner protection pressure plate 8, and finally flows out from the edge of the fixed frame 1. This can prevent water from accumulating on the sealing surface or seeping into the sealing gap. When the sealing strip needs to be replaced, the corner protection pressure plate 8 can be removed by disassembling the fastening bolts 11. The old sealing strip can be directly taken out from the first sealing groove 3 and the second sealing groove 12. After replacing the new sealing strip, the corner protection pressure plate 8 can be replaced again and the bolts can be tightened to complete the maintenance. The whole process does not require cleaning glue or grinding the contact surface, and the operation is convenient.
