Description

Technical Field

[0001] This utility model relates to the field of track scale technology, specifically to a track scale. Background Technology

[0002] A rail scale is a specialized weighing device installed on railway tracks for the automatic weighing of railway vehicles and their cargo. Its core function is to enable dynamic weighing or static accurate measurement of trains without stopping or uncoupling. It is widely used in railway freight yards, ports, metallurgy, and other scenarios that require weighing in railway transportation.

[0003] Rail scales are primarily electronic. An electronic rail scale consists of a weighing platform, load cells, and control instruments. When a train passes over the weighing platform, the load cells convert the weight signal into an electrical signal that is easy to test. Finally, the weighing data is transmitted to the control instrument and uploaded in real time.

[0004] During weighing, multiple weighing sensors are installed to evenly distribute the weight and improve weighing accuracy and stability. During installation, steel plates are pre-embedded in the load-bearing platform, and multiple weighing sensors are installed in the load-bearing platform using anchor bolts, thereby weighing the passing trains and their cargo.

[0005] However, when repairing or replacing the load cells later, it is necessary to disassemble multiple anchor bolts. Since there are multiple load cells installed inside the load cell platform, disassembly is troublesome and time-consuming. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this utility model provide a track scale, which solves the technical problem that the installation of the weighing sensor in the load-bearing platform is troublesome and time-consuming due to the use of anchor bolts and steel plates.

[0007] According to one aspect, at least one embodiment of the present invention provides a rail scale, including a load-bearing platform, and further including load cells, quick-release boxes, cable protection assemblies, and cover plate assemblies. Four load cells are provided, and the four load cells are electrically connected in series via wires. Four quick-release boxes are provided, and each of the four quick-release boxes is fixedly installed inside the load-bearing platform. Four cable protection assemblies are provided, and each of the four cable protection assemblies is respectively provided on one of the four inner sidewalls of the load-bearing platform for protecting the cable. The cover plate assembly is detachably installed on the top of the quick-release box for protecting the load cells placed inside the quick-release box.

[0008] Furthermore, the load cell adopts a quick-connect interface with an IP68 waterproof rating. A weighing instrument is installed on the side of the load-bearing platform. The weighing instrument works with the load cell to collect data and shares the same design as the quick-connect interface. The load cell uses high-speed CAM bus communication technology, and the data from the load cell is uploaded and collected using a timed reporting mechanism.

[0009] Furthermore, the cable protection assembly includes a support block, a junction box, a mounting bracket, and a semi-circular cable protection cover. Two support blocks are provided, and both support blocks are fixedly installed on the inner side wall of the support platform. The junction box is fixedly installed on the side of the two support blocks, and a semi-circular cable placement groove is provided at the top of the junction box. Two mounting brackets are provided, and a slot is provided at the top of the support block. The mounting bracket is detachably installed in the slot. The semi-circular cable protection cover is fixedly installed at the bottom of the two mounting brackets.

[0010] Furthermore, the cover plate assembly includes a cover plate and a connecting plate. There are four cover plates, and each of the four cover plates has a mounting rod fixedly installed at its bottom end. Each quick-release box has a mounting groove at its top end that matches the bottom end of the mounting rod. There are four connecting plates, and each connecting plate is fixedly installed between two adjacent cover plates.

[0011] Furthermore, the quick-release box has U-shaped cable channels on two sides through which the wire passes.

[0012] Furthermore, a positioning block is fixedly installed on the side of the cover plate, and a groove is provided on the inner side wall of the support platform, and the positioning block is adapted to the groove.

[0013] Furthermore, the four quick-release boxes are respectively fixedly installed at the four corners inside the support platform.

[0014] Furthermore, when the weighing sensor is placed into the quick-release box, the outer wall of the weighing sensor is in contact with the inner wall of the quick-release box.

[0015] Furthermore, the area of ​​the cover plate is the same as the area of ​​the top of the quick-release box.

[0016] The beneficial effects of this utility model are as follows: In this invention, when installing the load cells inside the load-bearing platform, four load cells connected in series by wires are first placed into four quick-release boxes simultaneously. This allows the load cells to fit snugly inside the quick-release boxes, preventing them from shaking due to vibrations caused by passing trains. The wires are then routed through the U-shaped cable channel of the quick-release box and placed inside the junction box for protection. Finally, the top of the quick-release box is sealed with a cover plate assembly to protect the load cells inside. This method allows for quick installation and placement of the weighing sensor, and it can also be quickly removed during subsequent maintenance or replacement, making it convenient and time-saving.

[0026] like Figures 1-6As shown, this invention illustrates a track scale according to one embodiment of the present invention, including a load-bearing platform 1, and further including load cells 2, quick-release boxes 3, cable protection components, and cover plate 8. Four load cells 2 are provided, and the four load cells 2 are electrically connected in series via wires 11. Four quick-release boxes 3 are provided, and all four quick-release boxes 3 are fixedly installed inside the load-bearing platform 1. Four cable protection components are provided, and the four cable protection components are respectively provided on the four inner side walls of the load-bearing platform 1 for protecting the wires 11. The cover plate 8 is detachably installed on the top of the quick-release box 3 for protecting the load cells 2 placed inside the quick-release box 3.

[0027] like Figure 2 and Figure 5 As shown, when measuring the weight of trains and goods on a track scale, four load cells 2 are first placed into four quick-release boxes 3 respectively. Because when the load cells 2 are placed into the quick-release boxes 3, the outer side wall of the load cells 2 is in contact with the inner side wall of the quick-release box 3, so the load cells 2 can be firmly placed inside the quick-release box 3.

[0028] like Figure 3 box Figure 6 As shown, after placement, since the four weighing sensors 2 are connected in series via wires 11, the wires 11 can be protected by the wire protection assembly. The wire protection assembly includes a support block 4, a junction box 5, a mounting bracket 6, and a semi-circular wire protection cover 7. There are two support blocks 4, both of which are fixedly installed on the inner side wall of the load-bearing platform 1. The junction box 5 is fixedly installed on the side of the two support blocks 4, and a semi-circular wire groove is provided at the top of the junction box 5. There are two mounting brackets 6, and the top of the support block 4 has a slot. The mounting bracket 6 can be detachably installed in the slot. The semi-circular wire protection cover 7 is fixedly installed at the bottom of the two mounting brackets 6.

[0029] Specifically, after placement, since the quick-release box 3 has U-shaped cable channels on two sides for passing through the wires 11, the wires 11 are passed through the U-shaped cable channels, and then the wires 11 are placed in the semi-circular cable channels of the junction box 5. Then, the staff holds the semi-circular cable guard 7 and attaches its bottom end to the top of the junction box 5. At this time, the mounting bracket 6 is inserted into the slot of the support block 4 for fixation, thereby protecting the wires 11 in the junction box 5.

[0030] like Figure 4As shown, finally, the tops of the four quick-release boxes 3 are sealed by the cover plate 8 assembly. The cover plate 8 assembly includes cover plates 8 and connecting plates 9. There are four cover plates 8. The bottom of each of the four cover plates 8 is fixedly installed with a mounting rod 12. The top of each quick-release box 3 is provided with a mounting groove that matches the bottom of the mounting rod 12. There are four connecting plates 9. A connecting plate 9 is fixedly installed between each two adjacent cover plates 8.

[0031] Specifically, because the side of the cover plate 8 is fixedly installed with a positioning block 10, and the inner side wall of the support platform 1 is provided with a groove, and the positioning block 10 is adapted to the groove, when the four cover plates 8 are put together, the positioning block 10 can be aligned with the groove at the same time and then put down to achieve alignment. After the cover plates 8 are put together, the mounting rod 12 at the bottom of the cover plate 8 can be inserted into the mounting groove at the top of the quick-release box 3 to fix it. Since the area of ​​the cover plate 8 is the same as the area of ​​the top of the quick-release box 3, the top of the quick-release box 3 can be completely sealed.

[0032] Working principle: When installing the load cells 2, the operator first places the four load cells 2 into the four quick-release boxes 3 respectively. Then, the wires 11 are passed through the U-shaped cable trays and placed in the semi-circular cable trays of the junction box 5. The operator then holds the semi-circular cable guard 7 and attaches its bottom end to the top of the junction box 5. At this time, the mounting bracket 6 is inserted into the slot of the support block 4 for fixation, thereby protecting the wires 11 in the junction box 5.

[0033] After placement, hold the connecting plate 9 and simultaneously install the four cover plates 8 on the top of the four quick-release boxes 3. When the cover plates 8 are in place, the mounting rod 12 at the bottom of the cover plate 8 can be inserted into the mounting groove at the top of the quick-release box 3 to fix it and seal the top of the quick-release box 3, thereby protecting the internal weighing sensor 2.

[0034] When the train passes the rails on both sides of the weighing platform 1, the pressure of the wheels on the rails is transmitted to the weighing platform 1. The pressure on the weighing platform 1 causes the strain gauge inside the weighing sensor 2 to deform, resulting in a change in resistance. This change in resistance is then converted into a weak electrical signal, which is transmitted through a signal cable to a weighing instrument or control system located a few meters away from the side of the weighing platform 1. The system amplifies, filters, and processes the electrical signal, and finally converts the electrical signal into the corresponding weight value according to the preset calibration parameters. This value is then displayed and stored. Because the four quick-release boxes 3 are fixedly installed at the four corners inside the weighing platform 1, uniform weighing can be achieved.

[0035] It should be added that, because the load cell 2 uses high-speed CAM bus communication technology and the data of the load cell 2 is uploaded and collected using a timed reporting mechanism, when the host sends a reporting command, the load cell 2 immediately reports the internal collected data upon receiving the command. The bus uses an arbitration mechanism, where the load cell 2 with the lower ID value reports first, and the load cell 2 with the higher ID value waits for the load cell 2 with the lower ID value to finish reporting before reporting its data.

[0036] Furthermore, when the load cell 2 detects an error or internal fault, it will automatically analyze the cause of the fault and automatically upload the fault code to ensure the accuracy and reliability of the weighing data.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
