Description

Technical Field

[0001] This utility model belongs to the technical field of picking equipment, specifically, it relates to an ultra-low height weighing RGV. Background Technology

[0002] RGV, or Automated Guided Vehicle, is an unmanned intelligent material handling device that runs on a fixed track. Guided by the track and controlled by a system (such as a PLC), it automatically travels between workstations according to preset instructions to complete tasks such as material transport and transfer. It is commonly used in various high-density storage systems such as automated warehouses. RGVs are characterized by large load capacity, high positioning accuracy, stable operation, strong anti-interference capabilities, and relatively low maintenance costs, significantly improving logistics efficiency and automation levels.

[0003] Patent CN221215802U discloses an RGV trolley. By setting up a base, a carrier plate, and a support plate, when the moving mechanism moves along the base to the placement position of the goods, the support plate moves closer to the goods on the carrier plate to facilitate the insertion of the dragging component into both sides of the goods. The goods are dragged onto the support plate by sliding the dragging component on the side of the support plate. Finally, the moving mechanism slides on the base to realize the handling and transfer of goods. This achieves the simultaneous handling and transfer of goods, greatly improving the efficiency of picking up goods.

[0004] However, the mechanical structure of the RGV rail shuttle in the above technical solution requires a high-rigidity structural design for its frame to meet the load-bearing requirements of heavy loads and the layout requirements of the drive unit (including motor, reducer and transmission components). This results in an overall height that cannot meet the needs of working scenarios with strict space and height requirements. In addition, during the material transportation process, it is often necessary to weigh the materials. The RGV structure with weighing function is more complex. If the height is directly reduced, it will not only lead to insufficient structural strength or difficulty in the layout of the drive electrical unit, but also cause large vibration interference when the RGV weighing module and equipment are used together, affecting the weighing accuracy and having certain limitations. Utility Model Content

[0005] To address the technical problem that existing RGV rail shuttles with weighing functions have a relatively high overall height, which cannot be directly reduced, and thus cannot meet the usage requirements in work scenarios with strict space height requirements, this utility model provides an ultra-low height weighing RGV.

[0006] The objective of this utility model can be achieved through the following technical solutions: An ultra-low height weighing RGV includes an RGV rail shuttle body; a vehicle body traveling base is provided at the lower part of the RGV rail shuttle body; a horizontally arranged drive motor is fixedly installed on one side of the vehicle body traveling base near the middle; a reducer is provided on one side of the drive motor, and the reducer is connected to the output end of the drive motor; symmetrically arranged transmission shafts are provided on both sides of the reducer, and the transmission shafts are connected to the output end of the reducer via universal joints; the end of each transmission shaft away from the reducer is connected to a drive wheel axle via a universal joint.

[0007] Furthermore, the upper part of the RGV rail shuttle is equipped with a roller conveying mechanism.

[0008] Furthermore, the upper part of the roller conveying mechanism is provided with multiple long material frames.

[0009] Furthermore, the reducer and the drive wheel shaft are interconnected and drive each other via a transmission shaft.

[0010] Furthermore, RGV weighing modules are symmetrically arranged on both sides of the vehicle body's traveling base.

[0011] Furthermore, limit plates are provided on both sides of the vehicle body traveling base.

[0012] The beneficial effects of this utility model are: 1. This utility model effectively improves the overall compactness of the vehicle's base design by arranging the drive motor and reducer laterally, thereby reducing the vertical space occupation. This reduces the overall height of the RGV rail shuttle, optimizes the center of gravity of the equipment, enhances stability, and leaves more space for the layout of other components, facilitating subsequent maintenance and repair. The lateral arrangement also makes the overall structure more reasonable, helping to reduce noise and vibration during operation. It solves the technical problem that existing RGV rail shuttles with weighing functions have a high overall height and cannot be directly reduced, making them unsuitable for use in work scenarios with strict space and height requirements.

[0013] 2. By connecting universal joints to the end of the drive shaft near the reducer, this utility model not only improves the flexibility and stability of power transmission, but also allows the connection between the drive wheel shaft and the reducer to withstand certain angle changes and axial displacements. This not only effectively compensates for alignment errors caused by equipment vibration or position changes, but also reduces the risk of wear caused by deformation or misalignment of the transmission system.

[0014] 3. This utility model limits the position of the upper conveying beam of the vehicle body traveling base by setting limit plates on both sides of the vehicle body traveling base. This effectively prevents the upper conveying beam from lateral displacement during operation and ensures that it always stays within the predetermined track. This improves the safety and stability of the conveyed materials, prevents the conveying beam from swaying left and right, increases the stability of the vehicle body traveling base, and increases its practicality.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figures 1-2As shown, an ultra-low-height weighing RGV includes an RGV rail shuttle body 1; a roller conveyor mechanism 4 is provided on the upper part of the RGV rail shuttle body 1, which is used for efficient transportation and sorting of goods. Through the rotation of the rollers, the goods can move smoothly along the conveying path, reducing the labor intensity of manual handling and improving the work efficiency; multiple long material frames 10 (four in this embodiment) are provided on the upper part of the roller conveyor mechanism 4, which are used to carry, position and transfer long strip materials or parts, such as metal profiles, pipes, plates or specific industrial components; a vehicle body traveling base 2 is provided on the lower part of the RGV rail shuttle body 1. The base is made of high-strength materials and can withstand a large load, ensuring the weighing capacity under the low structure while ensuring the stability and flexibility of the whole vehicle.

[0018] Please see Figures 3-5 As shown, RGV weighing modules 3 are symmetrically arranged on both sides of the vehicle body traveling base 2. These RGV weighing modules 3 are used to achieve real-time, accurate, and dynamic weighing of materials during RGV operation. A horizontally arranged drive motor 6 is fixedly installed on one side of the vehicle body traveling base 2 near the center. A reducer 7 is installed on one side of the drive motor 6 and is connected to the output end of the drive motor 6. The reducer 7 is used to reduce the speed of the drive motor 6 while increasing the output torque to meet the power requirements of the vehicle body traveling base 2 during operation. Through the transmission of the reducer 7, smoother start-up and stopping can be achieved, avoiding the impact force caused by instantaneous acceleration or deceleration, thereby protecting the safety of equipment and goods.

[0019] The reducer 7 has symmetrically arranged drive shafts 5 on both sides, and the drive shafts 5 are connected to the output end of the reducer 7 via universal joints 8. The end of the drive shaft 5 away from the reducer 7 is connected to a drive wheel shaft (not shown in the figure) via universal joints 8. The reducer 7 and the drive wheel shaft are connected and transmitted to each other via the drive shaft 5. The drive wheel shaft is used to drive the drive wheel to rotate, thereby driving the RGV rail shuttle body 1 to run on the track.

[0020] Limiting plates 9 are provided on both sides of the vehicle body traveling base 2. The height of the limiting plates 9 is higher than that of the vehicle body traveling base 2. The limiting plates 9 are used to limit the position of the upper conveying beam of the vehicle body traveling base 2, prevent the conveying beam from swaying left and right, increase the stability of the vehicle body traveling base 2, and also effectively limit the lateral movement of the upper conveying beam, ensuring that the conveying beam stays within the predetermined track during operation, and avoiding material falling or improper handling caused by swaying.

[0021] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below: This invention effectively improves the overall compactness of the vehicle body base 2 by arranging the drive motor 6 and reducer 7 laterally, thereby reducing the vertical space occupation. This reduces the overall height of the RGV rail shuttle body 1, optimizes the center of gravity of the equipment, enhances stability, and leaves more space for the layout of other components, facilitating subsequent maintenance and repair. The lateral arrangement also makes the overall structure more reasonable, helping to reduce noise and vibration during operation. It solves the technical problem that existing RGV rail shuttles with weighing functions have a high overall height and cannot be directly reduced, making them unsuitable for use in work scenarios with strict space and height requirements.

[0022] This invention improves the flexibility and stability of power transmission by connecting universal joints 8 to the end of the drive shaft 5 near the reducer 7. The introduction of universal joints 8 also enables the connection between the drive wheel shaft and the reducer 7 to withstand certain angle changes and axial displacements. This not only effectively compensates for alignment errors caused by equipment vibration or position changes, but also reduces the risk of wear caused by deformation or offset of the transmission system.

[0023] This utility model, by setting limit plates 9 on both sides of the vehicle body traveling base 2, limits the position of the upper conveying beam of the vehicle body traveling base 2, effectively preventing the upper conveying beam from lateral displacement during operation, ensuring that it always stays within the predetermined track, thereby improving the safety and stability of conveying materials, preventing the conveying beam from swaying left and right, increasing the stability of the vehicle body traveling base 2, and increasing its practicality.
