Description

Technical Field

[0001] This utility model relates to the field of railway freight technology, and in particular to a dual-platform digital indicating track scale. Background Technology

[0002] The dual-platform digital indicating rail scale is a core piece of equipment in the modern railway freight field used for accurate measurement of the load of open wagons. It undertakes key functions of trade settlement, transportation safety supervision and production management. With two independent weighing platforms as its core mechanical structure, and equipped with digital weighing sensors, signal acquisition and processing modules and display systems, it can realize continuous weighing of railway freight cars without stopping. The platform transmits the weight of the vehicle to the sensor, which converts the physical deformation into digital electrical signals. After being filtered and compensated by the acquisition card, the digital instrument calculates and displays the weight of a single wagon and the total weight of the entire train. At the same time, the data is uploaded to the management system for archiving.

[0003] The dual-platform digital indicating rail scale avoids the problems of signal interference and discontinuous measurement that occur with traditional analog rail scales by using dual-platform bearing load and digital signal transmission. It enables rapid weighing and data visualization of freight cars. Due to the space constraints of the equipment's mechanical structure, existing rail scales can only install four weighing sensors under each weighing platform, which are evenly distributed at the four corners of the platform. When a railway wagon enters the platform, the pressure of the wheel on the platform is mainly concentrated in the middle area, while the sensors at the four corners can only collect the force signal at the edge of the platform. Since the platform is a rigid steel structure, the force in the middle area cannot be effectively transmitted to the four corner sensors, resulting in deviations in the weight signals collected by the sensors. This leads to an uneven phenomenon where the force is greater in the middle and less on the sides, resulting in large measurement errors. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-4 An embodiment of this utility model is provided: a double-platform digital indicator rail scale, including a tipper 1. The tipper 1 has two mounting slots 2 on both the left and right sides inside. The mounting slots 2 are all equipped with detection mechanisms 3. The detection mechanisms 3 are used to improve weighing accuracy. The tipper 1 has anti-loosening mechanisms 4 on both the left and right sides of the top. The anti-loosening mechanisms 4 are used to prevent the rail from jumping.

[0033] The testing mechanism 3 includes multiple fixed boxes 31. The bottom of the multiple fixed boxes 31 is fixedly connected to the bottom of the inner side of multiple mounting slots 2. Multiple fixed blocks 32 are fixedly connected to the bottom of the inner side of each of the multiple fixed boxes 31. Weighing sensors 33 are fixedly connected to the top left and right sides of the multiple fixed blocks 32. Slide rails 34 are slidably connected to the top left and right sides of the tipper 1. Extrusion strips 35 are fixedly connected to the bottom of each of the two slide rails 34. Fixing components 36 are provided between adjacent fixed blocks 32. Extrusion components 37 are provided at the bottom of each of the two extrusion strips 35. A receiving component 38 is provided on the left side inside the tipper 1. Protective components 39 are provided on the left and right sides inside the tipper 1.

[0034] Specifically, the fixing boxes 31 are placed into the mounting slots 2 on the left and right sides inside the tipper 1, so that the bottom of the fixing boxes 31 fits against the bottom of the inner side of the mounting slot 2. The cooperation between the fixing boxes 31 and the mounting slots 2 provides a mounting base for the fixing blocks 32. Then, multiple fixing blocks 32 are fixed to the bottom of the inner side of the fixing boxes 31. Adjacent fixing blocks 32 are connected by fixing components 36. The cooperation between the fixing components 36 and the fixing blocks 32 prevents the fixing blocks 32 from shifting during the weighing process and ensures the stability of the position of the weighing sensor 33.

[0035] Install slide rail 34 on the top left and right sides of tipper 1, so that the extrusion strip 35 at the bottom of slide rail 34 is aligned with the weighing sensor 33 at the top of fixed block 32. The sliding cooperation between slide rail 34 and tipper 1 makes it easy to adjust the position of slide rail 34, ensuring that extrusion strip 35 and weighing sensor 33 are accurately aligned. After adjustment, extrusion strip 35 and fixed block 32 are connected by extrusion assembly 37. Through the cooperation between extrusion assembly 37, extrusion strip 35 and fixed block 32, extrusion strip 35 is tightly attached to weighing sensor 33 to avoid gaps causing weighing errors.

[0036] During weighing operations, the external rail vehicle enters the slide rail 34, and the vehicle's weight is transferred to the extrusion bar 35 through the slide rail 34. The extrusion bar 35 exerts pressure on the weighing sensor 33 below. The weighing sensor 33 converts the pressure signal into an electrical signal and transmits it to the receiving component 38 on the left side inside the tipper 1. The receiving component 38 processes the signal and outputs the weighing data, thus achieving accurate weighing of the vehicle. Through the cooperation of the weighing sensor 33, the extrusion bar 35, and the receiving component 38, the mechanical pressure is converted into a recognizable electrical signal, realizing the digital output of the weighing data and improving weighing accuracy.

[0037] The protective components 39 on the left and right sides inside the tippler 1 cover the outside of the detection mechanism 3. Through the cooperation of the protective components 39 with the tippler 1 and the fixed box 31, external dust and impurities are prevented from entering the detection mechanism 3, so as to avoid affecting the normal operation of the weighing sensor 33 and the fixed component 36. During the weighing process, if the slide rail 34 shows a tendency to jump, the anti-loosening mechanism 4 on the left and right sides of the top of the tippler 1 is activated. Through the cooperation of the anti-loosening mechanism 4 with the slide rail 34 and the tippler 1, the jumping of the slide rail 34 is suppressed, ensuring the stability of the weighing process.

[0038] When maintaining the testing mechanism 3, check the connection status between the fixing component 36 and the fixing block 32, and tighten any loose parts; check the fit between the weighing sensor 33 and the compression strip 35, and clean any impurities from the contact area; check the integrity of the protective component 39, and replace any damaged parts. This achieves accurate weighing and stable operation, ensuring the reliable operation of the dual-platform digital indicating rail scale.

[0039] Reference Figures 1-5The anti-loosening mechanism 4 includes two fixing bars 41. The bottom of the two fixing bars 41 is fixedly connected to the top left and right sides of the tipper 1, respectively. The two fixing bars 41 are provided with slots 42 between each other. The top left and right sides of the tipper 1 are fixedly connected with fixing plates 43. The opposite sides of the two fixing plates 43 are threaded with adjusting bolts 44.

[0040] Specifically, before weighing, the anti-loosening mechanism 4 and the slide rail 34 are assembled: when the slide rail 34 is slidably installed on the top left and right sides of the tipper 1, the left and right edges of the slide rail 34 are embedded in the slots 42 between adjacent fixing strips 41. Through the cooperation of fixing strips 41, slots 42 and slide rail 34, the lateral movement range of the slide rail 34 is limited, preventing the slide rail 34 from shifting laterally due to the impact of the vehicle entering during the weighing process, and providing initial lateral limit for the slide rail 34.

[0041] After adjusting the position of the slide rail 34 to precisely align the compression bar 35 with the weighing sensor 33, rotate the adjusting bolt 44 on the side of the fixing plate 43 away from the slide rail 34. Since the adjusting bolt 44 is threadedly connected to the fixing plate 43, the adjusting bolt 44 moves towards the slide rail 34 during rotation until the end of the adjusting bolt 44 is in contact with the outer wall of the slide rail 34. Through the cooperation of the adjusting bolt 44, the fixing plate 43, and the slide rail 34, lateral pressure is applied from the outside of the slide rail 34, further restricting the lateral displacement of the slide rail 34 and suppressing the vertical jumping tendency of the slide rail 34, ensuring that the slide rail 34 remains stable during the weighing process.

[0042] During weighing operations, an external rail vehicle enters the slide rail 34, and the vehicle's weight is transmitted to the compression bar 35 through the slide rail 34. The compression bar 35 generates pressure on the weighing sensor 33, which converts the pressure signal into an electrical signal and transmits it to the receiving component 38. The receiving component 38 processes the signal and outputs the weighing data. During this process, if the slide rail 34 jumps or shifts due to vibrations from the vehicle, the slot 42 of the fixing bar 41 will block the lateral movement of the slide rail 34, and the adjusting bolt 44 will press against the slide rail 34 from the outside. Through the cooperation of the anti-loosening mechanism 4 and the slide rail 34, the jumping and shifting of the slide rail 34 are effectively suppressed, avoiding uneven force on the weighing sensor 33 due to the instability of the slide rail 34, thus ensuring the accuracy of the weighing data.

[0043] Check the connection status between the fixing bar 41 and the tipper 1 to ensure that the fixing bar 41 is not loose; check the thread fit between the adjusting bolt 44 and the fixing plate 43, clean the impurities in the threaded part, and ensure that the adjusting bolt 44 can rotate smoothly; check the fit clearance between the slot 42 and the slide rail 34. If the clearance is too large, adjust the position of the adjusting bolt 44. This achieves stability and accuracy in the weighing process and provides support for the reliable operation of the dual-platform digital indicating rail scale.

[0044] Reference Figures 3-4The fixing component 36 includes multiple fixing rods 362, the outer walls of which are slidably connected to adjacent fixing blocks 32. Circular holes 361 are provided on the left and right sides of adjacent fixing blocks 32, and the fixing rods 362 are slidably connected within the circular holes 361 of adjacent fixing blocks 32. The extrusion component 37 includes two extrusion plates 371, the tops of which are fixedly connected to the bottoms of two extrusion strips 35. Multiple extrusion heads 372 are fixedly connected to the left and right sides of the bottom of the two extrusion plates 371. The receiving component 38 includes a digital junction box 382, ​​the bottom of which is installed on the inner left side of the tipper 1. An installation hole 381 is provided on the inner left side of the tipper 1. The bottom of the digital junction box 382 is fixedly connected to the bottom of the installation hole 381, and signal receiving lines 383 are fixedly connected to the left and right sides of the installation hole 381.

[0045] Specifically, when assembling the testing mechanism 3, after fixing the fixing block 32 to the bottom of the inner side of the fixing box 31, the fixing rod 362 is inserted into the round holes 361 on the left and right sides of the adjacent fixing block 32. The outer wall of the fixing rod 362 fits against the inner wall of the round hole 361. Through the cooperation of the fixing rod 362, the round hole 361, and the fixing block 32, the adjacent fixing blocks 32 are connected to prevent the fixing block 32 from shifting laterally due to force during the weighing process. This ensures that the position of the weighing sensor 33 on the top of the fixing block 32 is stable, providing a reliable foundation for subsequent pressure transmission.

[0046] When the extrusion assembly 37 is installed, the top of the extrusion plate 371 is fixed to the bottom of the extrusion strip 35, and the extrusion head 372 at the bottom of the extrusion plate 371 is aligned with the top of the load cell 33. When the slide rail 34 is subjected to force and transmits pressure downward, the extrusion strip 35 drives the extrusion plate 371 to move downward, and the extrusion head 372 contacts the top of the load cell 33 and applies pressure. Through the cooperation of the extrusion head 372, the extrusion plate 371, and the load cell 33, the pressure is concentrated and transmitted to the load cell 33, avoiding pressure dispersion that leads to weighing errors and improving the accuracy of pressure transmission.

[0047] During weighing operations, the load cell 33 converts the pressure signal into an electrical signal, which is transmitted to the digital junction box 382 inside the mounting hole 381 via the signal receiving line 383. The digital junction box 382 aggregates and processes the signals transmitted by multiple load cells 33 and outputs unified weighing data. Through the cooperation of the signal receiving line 383, the load cells 33, and the digital junction box 382, ​​stable transmission of electrical signals is ensured, and signal loss or interference is avoided. Through the cooperation of the digital junction box 382 and the mounting hole 381, a fixed installation position is provided for the digital junction box 382, ​​preventing it from shifting when the tippler 1 is operating.

[0048] During the weighing process, the fixing bar 41 and adjusting bolt 44 of the anti-loosening mechanism 4 suppress the slip rail 34 from jumping, and the protective component 39 prevents impurities from entering. During maintenance, check the fit between the fixing rod 362 and the round hole 361, and clean the internal impurities; check the integrity of the extrusion head 372 and replace the worn extrusion head 372; check the connection between the signal receiving line 383 and the digital junction box 382 to ensure smooth signal transmission. This achieves stability of the three components of the detection mechanism, accurate pressure transmission, and efficient signal processing, providing comprehensive protection for weighing accuracy and operational stability.

[0049] Reference Figures 1-2 The protective component 39 includes two baffles 391, the bottoms of which are respectively installed on the left and right sides of the inner bottom of the tipper 1. Mounting plates 392 are fixedly connected between adjacent baffles 391. Fixing bolts 393 are threadedly connected inside the multiple mounting plates 392. The protective component 39 also includes two sealing rings 394, which are fixedly connected between adjacent baffles 391 on opposite sides. Sealing grooves 395 are provided on the left and right sides of the inside of the tipper 1. A weighing display 5 is fixedly connected to the top left side of the tipper 1, and multiple display screens 6 are fixedly connected to the right side of the weighing display 5.

[0050] Specifically, when installing the protective component 39, first place the two baffles 391 at the bottom left and right ends of the inner side of the tippler 1, so that the sealing ring 394 on the side of the baffle 391 away from each other is embedded in the sealing groove 395 on the left and right sides of the tippler 1. Through the cooperation of the sealing ring 394 with the baffle 391 and the sealing groove 395, the gap between the baffle 391 and the inner wall of the tippler 1 is filled, preventing external dust and liquid from entering the interior of the detection mechanism 3 through the gap, thus achieving preliminary sealing protection. Then, fix the mounting plate 392 between the two adjacent baffles 391, and rotate the fixing bolt 393 to make it pass through the mounting plate 392 and fix it to the inner wall of the tippler 1. Through the cooperation of the mounting plate 392 with the fixing bolt 393 and the baffle 391, the two baffles 391 are stably connected, preventing the baffles 391 from shifting when the tippler 1 is operating, and ensuring that the protective component 39 fully covers the detection mechanism 3.

[0051] Before weighing, the weighing display 5 is connected to the digital junction box 382 of the receiving component 38. The weighing data processed by the digital junction box 382 can be transmitted to the weighing display 5. During weighing, an external vehicle drives into the slide rail 34, and the pressure is transmitted to the weighing sensor 33 through the extrusion bar 35, extrusion plate 371, and extrusion head 372. The weighing sensor 33 transmits the electrical signal to the digital junction box 382 through the signal receiving line 383. After the digital junction box 382 summarizes and processes the data, it sends it to the weighing display 5. The weighing display 5 then displays the data synchronously on multiple display screens 6. Through the cooperation of the weighing display 5, the digital junction box 382, ​​and the display screens 6, the weighing data can be presented on multiple devices, making it easier for operators to read the data from different angles and improving the convenience of operation.

[0052] During the weighing process, the fixing bar 41 and adjusting bolt 44 of the anti-loosening mechanism 4 suppress the jumping of the slide rail 34, and the baffle 391 and sealing ring 394 of the protective component 39 prevent impurities from entering. During maintenance, check the fit between the sealing ring 394 and the sealing groove 395, and replace the aged sealing ring 394; check the threaded connection between the fixing bolt 393 and the mounting plate 392, and tighten the loose fixing bolt 393; check the connection between the weighing display 5 and the display screen 6 to ensure smooth data transmission. This achieves protection of the detection mechanism 3 and intuitive data presentation, providing more comprehensive protection for the reliable operation of the dual-platform digital indicating track scale.

[0053] Working principle: The fixing boxes 31 are placed into the mounting slots 2 on the left and right sides of the inside of the tipper 1, so that the bottom of the fixing boxes 31 fits against the bottom of the inner side of the mounting slot 2. The cooperation between the fixing boxes 31 and the mounting slots 2 provides a mounting base for the fixing blocks 32. Then, multiple fixing blocks 32 are fixed to the bottom of the inner side of the fixing boxes 31. The fixing rods 362 are inserted into the round holes 361 on the left and right sides of the adjacent fixing blocks 32. The outer wall of the fixing rods 362 fits against the inner wall of the round holes 361. The cooperation between the fixing rods 362, the round holes 361, and the fixing blocks 32 connects the adjacent fixing blocks 32, preventing the fixing blocks 32 from shifting laterally due to force during the weighing process. This ensures that the position of the weighing sensor 33 on the top of the fixing block 32 is stable, providing a reliable foundation for subsequent pressure transmission.

[0054] Fix the top of the extrusion plate 371 to the bottom of the extrusion strip 35, so that the extrusion head 372 at the bottom of the extrusion plate 371 is aligned with the weighing sensor 33 at the top of the fixing block 32; then install the slide rail 34 on the top left and right sides of the tipper 1, so that the extrusion strip 35 at the bottom of the slide rail 34 is precisely aligned with the extrusion plate 371. Adjust the position of the slide rail 34 by sliding it with the tipper 1 to ensure that the extrusion head 372 is completely aligned with the weighing sensor 33; after adjustment, connect the extrusion strip 35 and the fixing block 32 through the extrusion assembly 37. Through the cooperation of the extrusion assembly 37 with the extrusion strip 35 and the fixing block 32, the extrusion head 372 is tightly attached to the weighing sensor 33 to avoid gaps that may cause weighing errors.

[0055] During the adjustment of the slide rail 34 position, the left and right edges of the slide rail 34 are embedded into the slots 42 between adjacent fixing strips 41. Through the cooperation of fixing strips 41, slots 42, and slide rail 34, the lateral movement range of slide rail 34 is limited, preventing the slide rail 34 from shifting laterally due to the impact of a vehicle entering during the weighing process. This provides initial lateral limit for the slide rail 34. When the position of the slide rail 34 is adjusted to the point where the extrusion head 372 is precisely aligned with the weighing sensor 33, the adjusting bolt 44 on the side away from the fixing plate 43 is rotated. Since the adjusting bolt 44 is threadedly connected to the fixing plate 43, the adjusting bolt 44 moves towards the slide rail 34 during rotation until the end of the adjusting bolt 44 is in contact with the outer wall of the slide rail 34. Through the cooperation of adjusting bolt 44, fixing plate 43, and slide rail 34, lateral pressure is applied from the outside of the slide rail 34, further limiting the lateral displacement of the slide rail 34 and suppressing the vertical jumping tendency of the slide rail 34, ensuring that the slide rail 34 remains stable during the weighing process.

[0056] Two baffles 391 are placed on the bottom left and right sides of the inner side of the tippler 1, respectively, so that the sealing ring 394 on the side of the baffle 391 furthest from the baffle 391 is embedded in the sealing groove 395 on the left and right sides of the tippler 1. Through the cooperation of the sealing ring 394 with the baffle 391 and the sealing groove 395, the gap between the baffle 391 and the inner wall of the tippler 1 is filled, preventing external dust and liquid from entering the interior of the detection mechanism 3 through the gap, thus achieving preliminary sealing protection. Then, the mounting plate 392 is fixed between the two adjacent baffles 391, and the fixing bolt 393 is rotated to make it pass through the mounting plate 392 and be fixed to the inner wall of the tippler 1. With the cooperation of fixing bolts 393 and baffles 391, the two baffles 391 are stably connected to prevent the baffles 391 from shifting when the tippler 1 is operating, ensuring that the protective component 39 fully covers the detection mechanism 3. At the same time, the digital junction box 382 is fixed in the mounting hole 381 on the left side inside the tippler 1, so that the signal receiving line 383 is connected to the weighing sensor 33 and the digital junction box 382 respectively. The weighing display 5 is fixed on the top left side of the tippler 1, so that the weighing display 5 is connected to the digital junction box 382, ​​and multiple displays 6 are connected to the weighing display 5 to complete the data transmission path.

[0057] When a railway open wagon is pulled away from the wheel adder by a shunting locomotive, the vehicle number and model information are read and temporarily stored in an industrial computer under program control via a vehicle number identification antenna and radio frequency cable vehicle number identification host installed on the line. When the vehicle is pulled to the tipping position, which is exactly the effective weighing position of the track scale, the limit switch signal is triggered and read by the switch quantity acquisition device installed in the control room. After receiving the signal, the metering application software performs metering data acquisition. At this time, an external rail vehicle enters the slide rail 34, and the vehicle weight is transmitted to the extrusion bar 35 through the slide rail 34. The extrusion bar 35 drives the extrusion plate 371 to move down, and the extrusion head 372 generates pressure on the weighing sensor 33. The weighing sensor 33 converts the pressure signal into an electrical signal and transmits it to the digital junction box 382 through the signal receiving line 383. The digital junction box 382 summarizes and processes the signals transmitted by multiple weighing sensors 33 and sends the heavy vehicle metering value to the weighing display 5. The metering application software receives the heavy vehicle metering value of the track scale weighing display 5 in real time and temporarily stores it in the program memory.

[0058] During the weighing process, if the slide rail 34 jumps or shifts due to vehicle vibration, the slot 42 of the fixing bar 41 will block the lateral movement of the slide rail 34, and the adjusting bolt 44 will press against the slide rail 34 from the outside. Through the cooperation of the anti-loosening mechanism 4 and the slide rail 34, the jumping and shifting of the slide rail 34 are effectively suppressed, and the uneven force on the weighing sensor 33 is avoided due to the instability of the slide rail 34. The baffle 391 and sealing ring 394 of the protective component 39 prevent external impurities from entering and ensure the normal operation of the internal components of the detection mechanism 3. When the open wagon tipped over and the coal was unloaded and returned to its position, the corresponding switch signal was triggered and read by the switch quantity acquisition device. After receiving the signal, the metering application software will perform the acquisition of metering data. At this time, the empty car weight is transmitted to the weighing sensor 33 through the slide rail 34, the extrusion bar 35, the extrusion plate 371, and the extrusion head 372. After signal conversion and processing, the track scale weighing display 5 outputs the empty car measurement value, and the metering application software temporarily stores the empty car measurement value in the program memory.

[0059] Subsequently, the metering application software matches the loaded vehicle metering value, the empty vehicle metering value, and the previously stored vehicle number information to complete the comprehensive metering information of this vehicle and store it in the database system. The metering application software then repeats the above process of loaded vehicle collection, empty vehicle collection, and data matching for the next vehicle to achieve continuous metering operation.

[0060] When maintaining the testing mechanism 3, check the fit between the fixing rod 362 and the round hole 361, and clean the internal impurities; check the integrity of the extrusion head 372, and replace the worn extrusion head 372; check the fit between the weighing sensor 33 and the extrusion head 372, and clean the impurities at the contact points. When maintaining the anti-loosening mechanism 4, check the connection status between the fixing strip 41 and the tipper 1, and ensure that the fixing strip 41 is not loose; check the thread fit between the adjusting bolt 44 and the fixing plate 43, clean the impurities at the threaded parts, and ensure that the adjusting bolt 44 can rotate smoothly; check the fit clearance between the slot 42 and the slide rail 34, and if the clearance is too large, adjust the position of the adjusting bolt 44. When maintaining the protective component 39, check the fit status between the sealing ring 394 and the sealing groove 395, and replace the aged ones. The sealing ring 394; check the threaded connection between the fixing bolt 393 and the mounting plate 392, and tighten any loose fixing bolts 393. When maintaining the receiving, display and vehicle identification system, check the connection between the signal receiving line 383 and the digital junction box 382 and the weighing sensor 33 to ensure smooth signal transmission; check the connection between the weighing display 5 and the display screen 6 to ensure normal data display; check the connection between the vehicle number identification antenna, the radio frequency cable and the vehicle number identification host to ensure accurate vehicle information reading; it realizes accurate vehicle information identification, accurate weighing data collection and comprehensive metrological information matching and storage, while ensuring stable operation and long-term equipment operation, providing comprehensive support for the reliable application of dual-platform digital indicating rail scales in railway open wagon weighing scenarios.
