Description

Technical Field

[0001] This utility model relates to the field of vehicle dynamic weighing technology, and more specifically, to a dynamic weighing module. Background Technology

[0002] Highways and other high-grade roads have extensive requirements for controlling vehicle overloading. Dynamic weighing systems are widely used in highway entrance overloading control and turn-back, off-site overloading control, and traffic data collection. Among these, dynamic weighing modules based on bridge-type pressure sensors are increasingly prevalent. These modules are typically embedded in the concrete subgrade, with their surface flush with the road surface. When a vehicle wheel runs over the dynamic weighing module, the resulting pressure acts on its surface. This pressure is transmitted to the weighing sensor within the module, generating a weak sensor signal.

[0003] In current applications, improving the accuracy of dynamic weighing systems in measuring the weight of moving vehicles is a crucial issue that urgently needs to be addressed in the development and application of dynamic weighing systems. Furthermore, reducing the production and maintenance costs of dynamic weighing systems, and improving the reliability of system operation, are also important factors that cannot be ignored in practical applications. Improving the dynamic weighing modules used in dynamic weighing systems through technical means is of great significance in solving the aforementioned problems.

[0004] The limited thickness of the concrete pavement where the dynamic weighing module is embedded restricts the module's dimensions in the thickness direction, making the structural design of a dynamic weighing module capable of high-precision measurement extremely difficult. This results in low measurement accuracy, unstable performance, short service life, and high production and maintenance costs, affecting the overall measurement results of the dynamic weighing system and increasing the overall cost of its use and maintenance.

Detailed Implementation

[0043] Various embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0044] This utility model provides a dynamic weighing module, see [link to related documentation] Figures 1 to 6 The dynamic weighing module includes: a hybrid structural beam 101, a weighing sensor 102, an elastic sealing body 103, and a base plate 105; wherein, the hybrid structural beam 101 includes a metal structural cavity beam 201 and a concrete structural beam 202, the top of the metal structural cavity beam 201 is provided with a concrete attachment groove 203, and the concrete structural beam 202 is disposed in the concrete attachment groove 203; sensor mounting cavities 204 are symmetrically provided at both ends of the bottom of the metal structural cavity beam 201, and the weighing sensor 102 is disposed in the sensor mounting cavity 204; the base plate 105 is fixedly connected to the bottom end of the weighing sensor 102, the top end of the weighing sensor 102 is fixedly connected to the metal structural cavity beam 201, and the elastic sealing body 103 is disposed in the gap between the metal structural cavity beam 201 and the base plate 105.

[0045] The dynamic weighing module is installed on the road to collect the dynamic pressure exerted on its surface by the tires of vehicles passing over it. A hybrid structural beam 101 is used to translate this dynamic pressure to the load cell 102, which is generated when vehicle wheels pass over the surface of the beam. The load cell 102 converts the dynamic pressure signal into a voltage signal. All the vehicle's wheels pass over multiple dynamic weighing modules, and the resulting dynamic pressure signals are transmitted to the dynamic weighing controller of the dynamic weighing system. The controller processes, analyzes, and calculates the data to obtain the vehicle's overall weight.

[0046] Specifically, in the hybrid structure beam 101, the metal structure cavity beam 201 is preferably formed by welding high-strength steel plates, giving it good strength and rigidity. The concrete structure beam 202 has internal metal reinforcement (preferably steel bars) to enhance tensile properties. The lower part of the concrete structure beam 202 is placed in the concrete adhesion groove 203 at the top of the metal structure cavity beam 201, which enhances the adhesion of the concrete structure beam 202 to the metal structure cavity beam 201. Bolt holes for fixing the load cell 102 are provided on the sensor mounting plate 301 and the base plate 105, respectively. The load cell 102 is fixedly connected to the sensor mounting plate 301 and the base plate 105 by bolts. After the load cell 102 is fixedly connected to the base plate 105 and the sensor mounting plate 301, there is a gap of 3mm to 10mm between the metal structure cavity beam 201 and the base plate 105, providing sufficient space for the load cell 102 to deform within its elastic limit. The elastic seal 103 installed in the gap between the metal structure cavity beam 201 and the base plate 105 can enhance the waterproof performance of the dynamic weighing module and prevent water from entering and damaging the dynamic weighing module installed after the roadbed.

[0047] Further, see Figures 7 to 12 The metal structure cavity beam 201 includes side upright plates 303, side blocking plates 304, sensor mounting plates 301, sensor mounting reinforcing plates 302, and cavity side blocking plates 307; the two side upright plates 303 are vertically arranged and spaced apart, the sensor mounting plate 301 is horizontally fixed between the two side upright plates 303, and the two side blocking plates 304 are vertically fixed at both ends of the side upright plates 303 and the sensor mounting plate 301; the upper ends of the two side upright plates 303 and the two side blocking plates 304 are also included. The upper end of plate 304 and the sensor mounting plate 301 surround to form the concrete attachment groove 203; two cavity side blocking plates 307 are vertically fixed between the two side upright plates 303, and the top of the cavity side blocking plate 307 is fixedly connected to the bottom of the sensor mounting plate 301. The lower ends of the two side upright plates 303, the lower ends of the side blocking plate 304, the cavity side blocking plate 307 and the sensor mounting plate 301 surround to form the sensor mounting cavity 204.

[0048] Specifically, the sensor mounting plate 301 is horizontally fixed to the upper part of the two side uprights 303. The top surface of the sensor mounting plate 301 is 5mm to 50mm lower than the top surface of the side uprights 303, meaning the depth of the formed concrete attachment groove 203 is 5mm to 50mm. The two cavity side blocking plates 307 are symmetrically arranged with the middle position of the side uprights 303 as the center, so that the two sensor mounting cavities 204 formed are symmetrical with the middle position of the side uprights 303. The depth of the formed sensor mounting groove is less than the height of the load cell 102, so that after the load cell 102 is connected to the base plate 105, there can be a gap between the metal structure cavity beam 201 and the base plate 105.

[0049] Furthermore, the metal structure cavity beam 201 also includes a sensor mounting reinforcing plate 302, an upper rib plate 305, a lower rib plate 306, and a cavity lower blocking plate 308; the two sensor mounting reinforcing plates 302 are respectively stacked and fixed at both ends of the top surface of the sensor mounting plate 301 at positions corresponding to the sensor mounting cavity 204; the two upper rib plates 305 are vertically and spaced apart at the middle position of the top surface of the sensor mounting plate 301, and the two ends of the upper rib plates 305 are respectively fixedly connected to the two upper rib plates 306. The sensor mounting reinforcement plate 302 is located at the end of the sensor mounting plate 301; the lower rib plate 306 is vertically positioned in the middle of the bottom surface of the sensor mounting plate 301, and the two ends of the lower rib plate 306 are respectively fixedly connected to the two cavity side blocking plates 307; the cavity lower blocking plate 308 is horizontally fixed between the bottom ends of the two cavity side blocking plates 307, and the two cavity side blocking plates 307, the two side upright plates 303, the sensor mounting plate 301 and the cavity lower blocking plate 308 surround to form a weight-reducing and reinforced cavity 205.

[0050] Specifically, by stacking a sensor mounting reinforcement plate 302 on the top surface of the sensor mounting plate 301 at a position corresponding to the sensor mounting cavity 204, the strength and stiffness of the maximum stress position of the metal structure cavity beam 201 are enhanced. By setting two upper ribs 305 at intervals along the width direction at the middle position of the top surface of the sensor mounting plate 301, the strength and stiffness of the middle section of the metal structure cavity beam 201 are enhanced, and the adhesion of the concrete structure beam 202 in the concrete attachment groove 203 at the top of the metal structure cavity beam 201 is also enhanced. The concrete structure beam 202 is formed by the curing of mortar poured into the concrete attachment groove 203, and the internal strength and tensile properties are increased through the synergistic effect of the metal reinforcement and the upper ribs 305. By setting a lower rib plate 306 at the middle of the bottom surface of the sensor mounting plate 301 and setting a lower cavity block plate 308 between the bottom ends of the two cavity side block plates 307, the resulting weight-reducing and reinforced cavity 205 can reduce the overall weight of the metal structure cavity beam 201 while ensuring that it has sufficient strength and rigidity, reducing deformation when run over by vehicles, and improving the weighing accuracy of the dynamic weighing module.

[0051] Furthermore, the side uprights 303, side blocking plates 304, sensor mounting plates 301, sensor mounting reinforcing plates 302, cavity side blocking plates 307, upper ribs 305, lower ribs 306, and cavity lower blocking plates 308 of the metal structural cavity beam 201 are connected and welded together using mortise and tenon joints. During the fabrication of the metal structural cavity beam 201, the plates are first initially connected and positioned by mortise and tenon joints, and then reinforced using welding. Compared to traditional methods of assembly using marking lines or positioning fixtures, the mortise and tenon joint connection method of the metal structural cavity beam 201 simplifies the manufacturing process, reduces manufacturing costs, and improves processing efficiency.

[0052] Specifically, in this embodiment, the tenon and mortise structures of each plate in the metal structural cavity beam 201 are as follows: Figure 17As shown, in this embodiment, each long side of the sensor mounting plate 301 has six tenons, namely tenons 2 to 7 and tenons 9 to 14, which can be inserted into the corresponding mortises in the two side upright plates 303, namely mortises 3 to 8. Each short side of the sensor mounting plate 301 has one tenon, namely tenon 1 and tenon 8, which can be inserted into the mortises 3 in the side blocking plate 304. The sensor mounting reinforcement plate 302 is superimposed on the sensor mounting plate 301, and each of its long sides has two tenons, namely tenons 2 to 3 and tenons 4 to 5, which can be superimposed and inserted into the mortises 3, 4, 7, and 8 in the side upright plates 303. One short side of the sensor mounting reinforcement plate 302 has a tenon 1, which can be superimposed with the tenon 1 or tenon 8 of the sensor mounting plate 301 and inserted into the mortises 3 in the side blocking plate 304. The sensor mounting reinforcement plate 302 has two mortises, 1 and 2, on its other short side. The ends of the two upper ribs 305 are inserted into the mortises 1 and 2 of the sensor mounting reinforcement plate 302, respectively. Each of the vertical edges of the side panel 304 has two straight tenons, one upper and one lower, which can be inserted into the mortises on the short sides of the two side panels 303, respectively. The upper horizontal edge of the cavity side panel 307 has one vertical mortise in the middle, and the lower horizontal edge has three vertical mortises. The straight tenon of the lower rib 306 can be inserted into the vertical mortises in the middle of the upper and lower horizontal edges of the cavity side panel 307. The two vertical edges of the cavity side panel 307 each have two straight tenons (tenon 1, tenon 2, tenon 3, tenon 4), located near the right angle on the vertical edge, which can be inserted into the straight mortises (mortise 1, tenon 2, tenon 9, tenon 10) on the two side panels 303. The lower rib plate 306 has two straight tenons on each of its two short sides, located near the upper and lower right angles on the upright sides, which can be inserted into the upright mortises in the middle of the two cavity side blocking plates 307. The lower cavity blocking plate 308 has two straight tenons on each of its two short sides, located near the upper and lower right angles on the upright sides, which can be inserted into the upright mortises at both ends of the lower horizontal edges of the two cavity side blocking plates 307.

[0053] Further, see Figures 13-16 A groove 1051 is formed around the top edge of the base plate 105, and the elastic sealing body 103 is disposed in the groove 1051. Specifically, the groove 1051 on the base plate 105 is located 2mm to 8mm from the edge of the top surface of the base plate 105, and the groove 1051 is formed around the top surface of the base plate 105 with a depth of 0.5mm to 2mm. The groove 1051 on the base plate 105 can be used to hold the elastic sealing body 103 in place, preventing it from moving. The elastic sealing body 103 is made of a flexible material (such as rubber) and is embedded in the gap between the hybrid structure beam 101 and the base plate 105. It is also held in the groove 1051 of the base plate 105 to prevent movement. The elastic sealing body 103 can improve the waterproof performance of the dynamic weighing module. Further, as Figure 6As shown, the gap between the metal structural cavity beam 201 and the base plate 105 is also filled with elastic sealant 104, which is located on the outside of the elastic sealing body 103. The elastic sealant 104 filling the gap between the metal structural cavity beam 201 and the base plate 105 can further improve the waterproof performance of the dynamic weighing module. While enhancing the waterproof performance, the elastic sealing body 103 can also prevent excessive flow of elastic sealant 104 into the gap between the load cell 102 and the base plate 105, thus ensuring the accuracy of the load cell 102 when measuring pressure as much as possible.

[0054] Furthermore, the dynamic weighing module includes a reinforced concrete foundation mesh 106, which is disposed on the base plate 105. See also Figures 1 to 5 The concrete foundation reinforcement mesh 106 includes multiple transverse short bars and two longitudinal long bars interconnected with each other. The concrete foundation reinforcement mesh 106 is fixedly connected to the bottom of the base plate 105 by the multiple transverse short bars and can be connected to the base plate 105 by welding. The concrete foundation reinforcement mesh 106 and the base plate 105 are firmly connected as one unit, so that after the dynamic weighing module is installed on the concrete subgrade, the foundation of the dynamic weighing module is firmly embedded in the concrete subgrade by pouring mortar.

[0055] Furthermore, a waterproof separation layer 107 is provided on the outer peripheral side of the hybrid structural beam 101. Specifically, the waterproof separation layer 107 includes a flexible material layer and a rigid waterproof material layer. The flexible material layer wraps around the outer peripheral side of the hybrid structural beam 101, and the rigid waterproof material layer wraps around the outside of the flexible material layer. In this embodiment, a 1mm~3mm flexible material layer is used to wrap around the outer peripheral side of the hybrid structural beam 101, and then a 0.5mm~1.5mm rigid waterproof material layer is wrapped around the outside of the flexible material layer, so that it and the underlying flexible material layer together form the waterproof separation layer 107.

[0056] The manufacturing method of this dynamic weighing module is as follows:

[0057] Step S1: Cut the mortise and tenon structural components of the metal structural cavity beam 201, including components such as... Figure 17 The sensor mounting plate 301, two sensor mounting reinforcement plates 302, two side upright plates 303, two side blocking plates 304, two upper rib plates 305, one lower rib plate 306, two cavity side blocking plates 307, and one cavity lower blocking plate 308 are shown.

[0058] Step S2: Assemble the metal structure cavity beam 201 by inserting and connecting the mortise and tenon structural components.

[0059] Step S3: Weld and reinforce each mortise and tenon structural component.

[0060] Step S4: Concrete is poured into the concrete attachment groove 203 at the top of the metal structure cavity beam 201 and above to form a concrete structure beam 202.

[0061] Step S5: Embed the elastic sealant 103 into the gap between the hybrid structural beam 101 and the base plate 105, and let the elastic sealant 103 fall into the slot 1051 of the base plate 105. Then, fill the other gaps between the hybrid structural beam 101 and the base plate 105 with elastic sealant 104.

[0062] Step S6: Wrap the outer periphery of the hybrid structure beam 101 with a flexible material layer with a thickness of 1mm to 3mm, and then wrap a rigid waterproof material layer with a thickness of 0.5mm to 1.5mm on the outside of the flexible material layer, so that it and the flexible material layer below together form a waterproof separation layer 107.

[0063] Compared with the prior art, the dynamic weighing module provided by this utility model has the following advantages:

[0064] The concrete attachment groove at the top of the metal structure cavity beam strengthens the bond between the concrete structure beam and the metal structure cavity beam, thereby enhancing the overall strength and stiffness of the hybrid structure beam without changing the dimensions in the thickness direction.

[0065] By introducing a sensor mounting reinforcement plate, the strength and rigidity of the most stressed parts were enhanced.

[0066] The improved overall and local strength and stiffness of the hybrid structural beams allow them to maintain excellent alignment even under the pressure of heavy vehicles, preventing excessive deflection and reducing stress concentration within the structure. As a result, the weight of a wheel pressing on any point on the surface of the dynamic weighing module is accurately transferred to the weighing sensor, ensuring the accuracy of the weighing reading.

[0067] The mortise and tenon joint structure of the metal structural cavity beams reduces the overall weight of the structure while reinforcing key load-bearing components and minimizing stress concentration. This structure also simplifies the welding and installation process, reducing assembly costs.

[0068] In the gap between the base plate and the hybrid structural beam, an elastic sealant forms a sealing frame, which enhances the waterproof performance and avoids excessive injection of elastic sealant into the gap, thus preventing it from affecting the accuracy of the load cell.
