Description

Technical Field

[0001] This utility model relates to the field of cargo measurement technology, specifically to a railway freight cargo measurement device. Background Technology

[0002] As a crucial component of logistics and transportation, railway freight carries a significant amount of cargo. In this process, railway freight weighing devices play a vital role, their main function being to accurately measure the weight of goods in railway freight. These devices not only ensure the accuracy and safety of transportation but also directly impact multiple aspects such as freight calculation and loading optimization.

[0023] like Figures 1 to 4 As shown, a railway freight weighing device includes a weighing platform 1. Inclined blocks 2 are fixedly installed on the front and rear sides of the weighing platform 1. A display 3 is fixedly installed on the right side of the weighing platform 1. Two sets of mirror-distributed telescopic rod mechanisms 4 are installed on the top of the weighing platform 1. A height limit bar 5 is commonly installed at the top of the two sets of telescopic rod mechanisms 4. A convex groove 6 is formed at the bottom of the height limit bar 5. A protrusion 7 is provided at the top of each set of telescopic rod mechanisms 4, and each protrusion 7 is movably installed inside the convex groove 6. A drive mechanism 8 for adjusting the distance between the two sets of telescopic rod mechanisms 4 is provided on the top of the weighing platform 1. It should be noted that when weighing the goods, the two sets of telescopic rod mechanisms are adjusted in advance according to the height that the carriage can accommodate. The telescopic mechanism 4 is adjusted to raise or lower the height of the height limit bar 5 to a suitable position. The distance between the two sets of telescopic bar mechanisms 4 is then adjusted according to the width that the carriage can accommodate. Specifically, the distance between the two sets of telescopic bar mechanisms 4 is adjusted by controlling the drive mechanism 8. During the movement of each set of telescopic bar mechanisms 4, the protrusion 7 connected to it slides inside the convex groove 6. Then, the staff pushes the goods from the front of the weighing platform 1 to the top of the weighing platform 1 for weighing. The specific weight is displayed on the display 3. After the weighing is completed, the goods on the top of the weighing platform 1 are pushed down from the rear of the weighing platform 1. If the goods can pass smoothly between the two sets of telescopic bar mechanisms 4, it means that the volume of the goods can be placed inside the carriage.

[0024] like Figure 1 , Figure 2As shown, the telescopic rod mechanism 4 includes vertical rods 401. Two vertical rods 401 are provided on the top of the weighing platform 1. Trapezoidal grooves 402 are formed on the sides of the two vertical rods 401 that are close to each other. A trapezoidal rod 403 is movably installed inside each trapezoidal groove 402. Slotted holes 404 are formed on the sides of the two trapezoidal grooves 402 that are far apart from each other. Lead screws 405 are fixedly installed on the sides of the two trapezoidal rods 403 that are far apart from each other. The two lead screws 405 pass through adjacent slotted holes 404, and each lead screw 405 is threaded with a nut 406. Two protrusions 7 are respectively... The height limit bar 5 is fixedly installed at the top of two trapezoidal rods 403. A round hole 407 is provided on the side of each of the two vertical rods 401 that is close to each other. It should be noted that the extension and retraction of the two sets of telescopic rod mechanisms 4 can be adjusted according to the height that the carriage can accommodate, thereby raising or lowering the height of the height limit bar 5 to a suitable position. Specifically, the height limit bar 5 can be moved up or down. The up and down movement of the height limit bar 5 can be achieved by the two protrusions 7, which respectively drive the two trapezoidal rods 403 to move up and down. After the height of the height limit bar 5 is adjusted to a suitable level, the two nuts 406 can be rotated to fix the two trapezoidal rods 403 at the current height.

[0025] like Figures 1 to 3 As shown, the driving mechanism 8 includes a strip groove 801. The top of the weighing platform 1 has a strip groove 801. An mounting block 802 is fixedly installed on the inner top surface of the strip groove 801. A bidirectional lead screw 803 is movably installed between the two mounting blocks 802. A servo motor 805 is fixedly installed on the right side of the weighing platform 1. A rotating shaft 804 is fixedly connected to the output end of the servo motor 805. The rotating shaft 804 passes through the interior of adjacent circular holes 407. The end of the rotating shaft 804 away from the servo motor 805 passes through the adjacent mounting block 802 and is connected to the bidirectional lead screw 803. Moving blocks 806 are threaded to both ends of the bidirectional lead screw 803. Two connecting rods 807 are fixedly installed on the opposite sides. The end of each connecting rod 807 away from the moving block 806 is fixedly connected to the adjacent vertical rod 401. It should be noted that by starting the servo motor 805, the servo motor 805 can drive the rotating shaft 804 and the bidirectional lead screw 803 to reciprocate. The reciprocating rotation of the bidirectional lead screw 803 can drive the two moving blocks 806 to move closer or further apart. The movement of each moving block 806 drives the two connecting rods 807 connected to it to move synchronously. The movement of each pair of adjacent connecting rods 807 drives the vertical rod 401 connected to them to move synchronously, thereby adjusting the distance between the two sets of telescopic rod mechanisms 4.

[0026] like Figures 1 to 3As shown, the driving mechanism 8 also includes a slide groove 808. Two slide grooves 808 are provided on the top of the weighing platform 1. A slide rod 809 is movably installed inside each slide groove 808. Each slide rod 809 is fixedly connected to the adjacent vertical rod 401. It should be noted that the movement of each strip groove 801 drives the slide rod 809 connected to it to move synchronously. The movement of each slide rod 809 slides inside the corresponding slide groove 808. The slide rod 809 prevents the goods from falling into the strip groove 801 when being pushed.

[0027] like Figure 1 , Figure 2 As shown, a positioning mechanism 9 for positioning goods is rotatably installed on the telescopic rod mechanism 4 on the left side. An installation rod 10 is fixedly installed on the side wall of the vertical rod 401 on the left side. A sensor 11 is fixedly installed on the installation rod 10. A buzzer 12 is fixedly installed on the top of the height limit rod 5. It should be noted that if the thickness of the goods needs to be considered when loading them to the rear of the carriage, the positioning mechanism 9 should be adjusted in advance according to the space at the rear of the carriage. After pushing the goods to the top of the weighing platform 1, one corner of the goods can be pushed into the interior of the positioning mechanism 9. Then, the weight is measured and the sensor 11 detects the goods. If the sensor 11 does not detect the goods, it means that the thickness of the goods can be placed at the rear of the carriage. If the sensor 11 detects the goods, it means that the thickness is not suitable for placing them in the space at the rear of the carriage. The buzzer 12 will sound an alarm after receiving the signal.

[0028] like Figure 1 , Figure 4 As shown, the positioning mechanism 9 includes an actuator motor 901. The actuator motor 901 is fixedly installed on the side wall of the vertical rod 401 on the left side. A rectangular rod 902 is fixedly connected to the output end of the actuator motor 901. A convex groove 903 is opened on the side of the rectangular rod 902 near the display 3. A protrusion 904 is movably installed inside the convex groove 903. An elongated hole 905 is opened on the side of the rectangular rod 902 away from the display 3. A threaded rod 906 penetrating the elongated hole 905 is fixedly installed on the side wall of the protrusion 904. A nut 907 is threadedly connected to the threaded rod 906. A nut 907 is fixedly installed on the side of the protrusion 904 near the display 3. It should be noted that, based on According to the positioning rod 908 at the rear of the carriage, the positioning rod 908 moves and simultaneously drives the second protrusion 904 to slide synchronously inside the second convex groove 903. After the positioning rod 908 is adjusted to the correct position, the nut 907 can be turned to fix the positioning rod 908 in the current position. After pushing the goods to the top of the weighing platform 1, one corner of the goods can be pushed into the interior of the positioning mechanism 9. At this time, the goods come into contact with the positioning rod 908. Then, the sensor 11 detects the weight. When the goods are pushed down from the top of the weighing platform 1, the actuator motor 901 is started. The actuator motor 901 can drive the rectangular rod 902 to rotate 90 degrees, so that the goods can be smoothly unloaded from the top of the weighing platform 1.

[0029] In summary:

[0030] When weighing goods, the extension and retraction of the two sets of telescopic rod mechanisms 4 are adjusted in advance according to the height that the carriage can accommodate, so that the height of the height limit bar 5 is raised or lowered to a suitable position. Then, the distance between the two sets of telescopic rod mechanisms 4 is adjusted according to the width that the carriage can accommodate. Specifically, the distance between the two sets of telescopic rod mechanisms 4 is adjusted by controlling the drive mechanism 8. During the movement of each set of telescopic rod mechanisms 4, the protrusion 7 connected to it slides inside the convex groove 6. Then, the staff pushes the goods from the front side of the weighing platform 1 to the top of the weighing platform 1 for weighing. The specific weight is displayed on the display 3. After the weighing is completed, the goods on the top of the weighing platform 1 are pushed down from the rear side of the weighing platform 1. If the goods can pass smoothly between the two sets of telescopic rod mechanisms 4, it means that the volume of the goods can be placed inside the carriage.
