Description

Technical Field

[0001] This utility model relates to the field of measurement technology, and in particular to a truck scale weighing device. Background Technology

[0002] A truck scale (also known as a weighbridge) is a large weighing device fixed to the ground, primarily used to accurately measure the total weight of vehicles (and their cargo). It is one of the core metrological tools in logistics, warehousing, traffic management, and industrial production. Its core function is to achieve digital display and recording of weight through mechanical signal conversion, providing crucial data support for scenarios such as transaction settlement, inventory management, and overload control.

[0003] In the relevant technical solution, the weighbridge includes a concrete support base with a square mounting groove reserved in the base. The weighing body with a weighing sensor is embedded in the mounting groove, and the upper end of the weighing body is slightly higher than the upper end of the base.

[0004] In the above structural configuration, a gap is formed between the perimeter of the weighing body and the inner wall of the mounting groove in the base to prevent scratching between the base and the weighing body. However, when sewage or debris accumulates on the upper surface of the weighing body, this sewage or debris can easily enter the gap from the weighing body, potentially causing the gap to jam or sewage to accumulate in the mounting groove.

[0005] In addition, truck scales are generally exposed to the open environment, and rainwater or sand and debris from the outside can easily enter the gaps, causing the gaps to become stuck or sewage to accumulate. Utility Model Content

[0006] This utility model provides a truck scale weighing device, which can solve at least one of the above-mentioned technical problems.

[0007] To address the aforementioned technical problems, one or more embodiments of this utility model provide a truck scale weighing device, including a base with a through-mounting groove. A weighing body is embedded within the mounting groove, and the upper end of the weighing body is higher than the upper surface of the base. The height of the upper surface of the weighing body gradually decreases from its circumference to the center of the upper surface. A collection port is provided at the center of the upper surface of the weighing body, and the collection port vertically penetrates the weighing body. One side wall of the base along its width direction has a mounting opening, within which a detachable collection box is embedded. One end of the collection box is located outside the base, and the other end is inserted into the mounting groove of the base through the mounting opening and is positioned directly below the collection opening.

[0008] Furthermore, the weighing device has a length direction and a width direction. The base has ramps at both ends along the length direction and curtains at both ends along the width direction. One end of the curtain is connected to the edge of the base along the width direction, and the other end extends freely.

[0009] Furthermore, the weighing body has baffles at both ends along its width direction. One end of the baffle is rotatably connected to the weighing body, and the baffle can rotate to fit against the weighing body or rotate away from the weighing body and above the base.

[0010] The beneficial effects of one or more of the above technical solutions are as follows: In this design, the height of the upper surface of the weighing body gradually decreases from its surrounding contours to the center of the upper surface. A collection port is located at the center of the upper surface of the weighing body, and an installation port is located on one side wall of the base. A detachable collection box is embedded in the installation port. One end of the collection box is located outside the base, and the other end is inserted into the installation groove of the base through the installation port and is positioned directly below the collection port. This arrangement facilitates the collection of wastewater and debris from the weighing body under the influence of gravity into the collection port, and then into the collection box, and is intermittently discharged from the weighing device. In other words, this design reduces the probability of dirt and wastewater from the surface of the weighing body entering the gap between the weighing body and the base.

[0011] In this design, curtains are connected to both ends of the base along its width. One end of the curtain is connected to the edge of the base, while the other end extends freely. When the weighing device is not in use, the curtains can be used to cover the gaps at both ends of the weighing platform along its width, reducing the probability of rainwater or debris entering the gaps.

[0012] In this design, baffles are provided at both ends of the weighing body along its width. One end of each baffle is rotatably connected to the weighing body, allowing it to rotate to be flush with or away from the weighing body and positioned above the base. When using the weighing device, the baffles can be rotated to cover the gaps at both ends of the weighing platform along its width, further reducing the probability of contaminants entering the gaps on the upper surface of the weighing body.

[0015] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0016] See Figures 1-6 This embodiment provides a truck scale weighing device, including a base 2. The base 2 is integrally cast with reinforced concrete and has a reinforcing mesh embedded inside. The base 2 has dimensions of 18m in length, 3.4m in width, and 0.4m in height. The base 2 has a through-hole mounting groove 5, which is a rectangular groove with a length of 16m, a width of 3m, and a depth of 0.35m. The surface of the groove wall is finely polished to reduce friction with the weighing body 1. The weighing body 1 is embedded in the mounting groove 5. The weighing body 1 is welded from steel plates, and the upper end of the weighing body 1 is 15mm higher than the upper end surface of the base 2, forming an effective anti-collision edge. The height of the upper surface of the weighing body 1 gradually decreases from the perimeter to the center of the upper surface, with an inclination angle of 2°-3° to facilitate the flow of sewage and waste. A circular collection port 4 with a diameter of 150mm is provided at the center of the upper surface of the weighing body 1. The collection port 4 penetrates the weighing body 1 vertically, and the edges of the collection port 4 are rounded to prevent stress concentration. One of the side walls of the base 2 along the width direction has an installation opening with dimensions of 200mm in width, 180mm in height, and 250mm in depth. The inner wall is equipped with a stainless steel guide rail. A detachable collection box 3 is embedded in the installation opening. The collection box 3 is made of stainless steel, 2mm thick, and has an internal volume of 30L. One end of the collection box 3 is located outside the base 2 and is equipped with a sealing rubber gasket and a handle. The other end is inserted into the mounting groove 5 of the base 2 through the installation opening and is located directly below the collection opening 4. A positioning pin is provided between the collection box 3 and the installation opening to ensure that the collection box 3 is locked after the installation position is aligned.

[0017] In this embodiment, the weighing device has a length direction and a width direction. The base 2 has ramps at both ends along the length direction, with an inclination angle of 8°. The surface is provided with anti-slip grooves with a groove spacing of 100mm and a depth of 5mm. The base 2 has curtains 11 connected to both ends along its width direction. The curtains 11 are made of neoprene rubber. One end of the curtain 11 along its width direction is connected to the edge of the base 2 by a stainless steel pressure strip and bolts. The other end extends freely for 250mm. A counterweight is added to the free end to ensure that the curtain 11 hangs down naturally to form an effective seal. The gap between the curtain 11 and the surface of the weighing body 1 is controlled within 5mm, which can prevent debris from entering and avoid excessive friction when vehicles pass by.

[0018] In this embodiment, baffles 8 are provided at both ends of the weighing body 1 along its width direction. The baffles 8 are made of stainless steel. The baffles 8 can rotate to be in contact with the weighing body 1 or to be away from the weighing body 1 and above the base 2. An elastic buffer pad made of polyurethane is provided on the inner side of the baffles 8. When the baffles 8 are in contact with the weighing body 1, a seal is formed to prevent fine particles from entering the rotating mechanism.

[0019] In this embodiment, the baffle 8 and the weighing body 1 are rotatably connected via a rotating shaft 9. Self-lubricating bearings are provided at both ends of the rotating shaft 9 to ensure no jamming during long-term use. A limiting post 10 is provided on the side of the rotating shaft 9 furthest from its center on the weighing body 1. The limiting post 10 is threadedly connected to the edge of the upper surface of the weighing body 1. The limiting post 10 is used to stop the baffle 8, thereby limiting contact between the baffle 8 and the base 2, ensuring a 10-15mm gap between the baffle 8 and the upper surface of the base 2, and preventing contact between the baffle 8 and the base 2 from affecting the weighing of the weighing body 1.

[0020] In this embodiment, the baffle 8 can rotate to a first state and a second state. In the first state, the baffle 8 rotates towards the side closer to the center of the weighing body 1 until it is in contact with the weighing body 1. In the second state, the baffle 8 rotates towards the side farther from the center of the weighing body 1 until the angle with the horizontal plane is less than 30 degrees.

[0021] In this embodiment, the mounting slot is a square slot with a waterproof coating on the inner wall, made of epoxy resin-based waterproof material. The weighing body 1 includes a square plate and support columns 6. Multiple support columns 6 are evenly distributed, each with a cross-sectional dimension of 200mm × 200mm and a height of 400mm. The support columns 6 are fixed to the embedded parts in the square slot by M24 anchor bolts. A weighing sensor is installed between the square plate and the support columns 6.

[0022] In this embodiment, a guide tube is connected to the lower end of the collection port 4 to facilitate alignment with the collection box 3. The collection box 3 is divided into upper and lower layers. The upper layer is a filtration zone with a 30-mesh stainless steel filter screen, which can intercept solid particles with a diameter greater than 0.6mm. The lower layer is a sedimentation zone with a V-shaped bottom and an inclination angle of 15°.

[0023] In this embodiment, the upper surface of the weighing body 1 is decorated with a diamond-shaped anti-slip pattern with a pattern spacing of 30mm and a depth of 1.5mm. The edges are chamfered to ensure good anti-slip performance without affecting the flow of liquid.

[0024] Working principle: When using this device, first rotate the baffle 8 from the first state to the second state (the angle with the horizontal plane is less than 30 degrees). After the baffle 8 is in place, it is fixed in position by the limiting post 10. At this time, the sealing strip at the lower edge of the baffle 8 forms a small gap with the upper surface of the base 2 and does not contact the base 2, effectively covering the gap between the weighing body 1 and the base 2. At the same time, ensure that the curtain 11 hangs down naturally away from the weighing platform.

[0025] When a loaded vehicle drives onto the weighing body 1, the mud, sand, and other debris carried by the vehicle's tires flow towards the center along the 12°-3° inclined surface of the weighing body under the influence of gravity and tire pressure, eventually falling into the collection box 3 below through the collection port 4. The filter screen on the upper layer of the collection box 3 intercepts solid particles, while the liquid flows into the lower layer. During the weighing process, the load cell converts the pressure signal into an electrical signal, which is transmitted to the instrument via cable to display accurate weight data. In rainy weather, rainwater also flows along the inclined surface to the collection port 4, preventing water accumulation on the weighing surface from affecting weighing accuracy. When cleaning the collection box 3 is necessary, the operator simply pulls out the collection box 3, removes the filter screen, and cleans the solid debris; the entire process requires no tools.

[0026] When not in use, the baffle 8 can be rotated back to its first position and placed against the surface of the weighing body 1 to reduce space occupation. At this time, the curtain 11 can be flipped to the side of the weighing platform and placed on the weighing platform to cover the gap 7, thereby reducing the probability of rainwater or debris from the outside environment entering the gap 7.

[0027] It should be noted that the curtains and baffles are placed at the gaps at both ends of the weighing platform along the width direction to cover these gaps, but they do not cover the two ends of the weighing platform along the length direction.

[0028] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0029] Any aspects of this utility model not described in detail are known to those skilled in the art.
