Description

Technical Field

[0001] This utility model relates to the technical field of train water tank filling devices, specifically an automatic water supply device for railways. Background Technology

[0002] Refilling water into trains is a crucial operational process for ensuring passengers' water needs on both high-speed and regular trains. Each carriage has a water storage capacity of 300-500 liters, and operators must complete the water filling operation within a short time. The water filling operation mostly involves standardized actions such as pulling, inserting, and filling water pipes. In winter, operators must deal with water pipes freezing, and in summer, they must withstand high temperatures. Through pressurized water supply from storage tanks and a professional maintenance team, the station ensures that hundreds of carriages are refilled with water daily.

[0003] Currently, high-speed trains and other trains all use manual water filling. After the train arrives at the station, the operator needs to perform a series of actions to fill the water tank, such as opening the outer cover, opening the inner cover, and adding water. The existing manual water filling method has problems such as simple operation, poor outdoor working environment, and high labor intensity. In view of the technical problems of the existing technology, there is an urgent need to introduce an automated water filling device to replace manual water filling to improve efficiency and reduce the labor intensity of operators. This paper provides an automatic water filling device for railways to solve the above technical problems. Utility Model Content

Detailed Implementation

[0017] The technical solution of this utility model will be further described in detail below with reference to specific embodiments: For the first embodiment, please refer to... Figures 1-12An automatic water supply device for railways includes a ground rail 1, a sliding platform 2 slidably mounted on the ground rail 1, and a protective box 3 mounted on the sliding platform 2 that is horizontally corresponding to the water tank protective frame 7 of the train.

[0018] The water tank protective frame 7 is part of the train's water storage tank. A water tank connecting pipe 10 is installed inside the water tank protective frame 7. An inner cover 9 is installed on the water tank connecting pipe 10, and an outer cover 8 is installed above the inner cover 9. The outer cover 8 is slidably installed on the water tank protective frame 7 along an arc-shaped slide. The inner cover 9 is located below the outer cover 8 and is rotatably installed on the water tank protective frame 7. The bottom surface of the inner cover 9 abuts against the end of the water tank connecting pipe 10. The outer cover 8 and the inner cover 9 serve to protect the water tank connecting pipe 10. When it is necessary to add water to the train's water storage tank, the outer cover 8 and the inner cover 9 need to be opened in sequence, and water is added to the water storage tank through the water tank connecting pipe 10.

[0019] The protective box 3 is fixed on the sliding stage 2. A six-axis robot 4 is installed inside the protective box 3. A vision sensor 6 and a connector 11 located on one side of the vision sensor 6 are installed at the end of the six-axis robot 4. A connecting frame I12 and a connecting frame II20 are suspended inside the protective box 3. A water supply mechanism for docking with the water tank pipe 10 is installed on the connecting frame I12. An outer cover opening mechanism for opening the outer cover 8 is installed on the connecting frame II20. A longitudinal extension frame 5 is slidably installed inside the protective box 3. The sliding direction of the longitudinal extension frame 5 is perpendicular to the sliding direction of the sliding stage 2. An inner cover opening mechanism for opening the inner cover 9 is installed on the longitudinal extension frame 5.

[0020] Specifically, the outer cover opening mechanism includes a vacuum suction cup 17 fixed on a connecting frame II20, and a mating connector II23 that is adapted to connect to the connector 11 is fixed on the connecting frame II20. The six-axis robot 4 drives the vision sensor 6 to scan the position of the outer cover 8 and obtain position information to achieve visual positioning of the outer cover 8. Then, the connector 11 of the six-axis robot 4 docks with the mating connector II23 to achieve the gripping of the connecting frame II20. The connecting frame II20 moves with the six-axis robot 4 and finally adsorbs the vacuum suction cup 17 onto the outer cover 8. The movement of the robotic arm of the six-axis robot 4 causes the vacuum suction cup 17 to rotate the outer cover 8 to open it.

[0021] Specifically, the inner cover opening mechanism includes a rotating frame 25, on which a steering motor I14 is fixed. An extension arm 15 is coaxially fixed to the output shaft of the steering motor I14, and an inner cover actuating lever 16 is fixed to the end of the extension arm 15. The inner cover opening mechanism also includes a steering motor II19 fixed to a longitudinal extension frame 5. A rotating shaft 26 fixed to the rotating frame 25 is rotatably mounted on the longitudinal extension frame 5. The rotating shaft 26 is connected to the output shaft of the steering motor II19 via a right-angle coupling 24.

[0022] When the outer cover 8 is opened, the longitudinal extension frame 5 slides toward the water tank protective frame 7, causing the inner cover actuating rod 16 at the end of the extension arm 15 to move below the inner cover 9. The steering motor I14 drives the extension arm 15 and the inner cover actuating rod 16 to rotate, adjusting the inner cover actuating rod 16 to a horizontal state. Then, the steering motor II19 drives the rotating frame 25 to rotate together with the steering motor I14 through the right-angle coupling 24. At this time, the steering motor I14 can drive the extension arm 15 to rotate. At this time, the inner cover actuating rod 16 at the end of the extension arm 15 is lifted upward and actuates the inner cover 9 to open it. After connecting with the water tank pipe 10 through the water supply mechanism, the water tank is filled with water.

[0023] The sequential opening of the outer cover 8 and inner cover 9 achieves a high degree of automation, greatly reducing manual workload and the intensity of water filling operations. It can easily and efficiently complete the water filling of the train's water storage tank even in harsh external environments.

[0024] For the second embodiment, please refer to... Figures 1-12 In addition to the first embodiment, the water supply mechanism includes a water supply pipe 18 fixed on the connecting frame I12, a water supply connector 13 connected to the end of the water supply pipe 18, and a mating connector I22 that is adapted to connect to the connector 11 fixed on the connecting frame I12.

[0025] After the outer cover 8 and inner cover 9 are opened sequentially and kept open, the six-axis robot 4 drives the vision sensor 6 to scan the position of the water tank connector 10 and obtain position information. After the six-axis robot 4 sends the outer cover opening mechanism back into the protective box 3, the connector 11 of the six-axis robot 4 docks with the docking connector I22. The six-axis robot 4 then grasps the connecting frame I12 and extends it out of the protective box 3. The water inlet connector 13 then docks with the open water tank connector 10. Municipal water is then transported to the water inlet connector 13 through the water pipe 18 by a centrifugal pump, ultimately filling the train's water tank with water.

[0026] During the water filling process described above, the precise location of the water tank connection pipe 10, determined by the vision sensor 6, enables the water inlet connector 13 and the water tank connection pipe 10 to connect accurately and quickly, greatly improving the efficiency of the water filling operation.

[0027] In addition, a pressure sensor connector 27 is embedded in the side wall of the water inlet connector 13. A pressure sensor is installed on the pressure sensor connector 27. The pressure sensor connected to the pressure sensor connector 27 can detect the water pressure inside the water inlet connector 13. The pressure sensor will detect the water pressure change when the water is full. The water pressure of the water inlet connector 13 comes from the centrifugal pump. The control cabinet installed on the protective box 3 collects the water pressure signal, analyzes and processes it, and controls the centrifugal pump to stop adding water, realizing the water full detection function during the water adding process and avoiding overfilling.

[0028] In addition, movable doors 21 are slidably installed on both sides of the protective box 3, and the sliding platform 2 slides on the ground rail 1 to realize the sliding adjustment of the protective box 3 and correspond to the water tank protection frame 7 of the train. The movable doors 21 on both sides of the protective box 3 can be opened, that is, the train located on both sides of the protective box 3 can carry out the water tank filling operation, which greatly improves the operational flexibility and ease of use of this device.

[0029] In summary, this utility model uses a visual sensor 6 to visually scan the train's water tank connector 10, outer cover 8, and inner cover 9 to achieve visual positioning. A six-axis robot 4 grasps the outer cover opening mechanism, and the vacuum suction cup 17 connects with the outer cover 8 to open it. The longitudinal extension frame 5 in the inner cover opening mechanism moves towards the water tank protective frame 7, causing the inner cover lever 16 to open the inner cover 9. The six-axis robot 4 then grasps the water supply mechanism, and the water supply connector 13 connects with the water tank connector 10 to add water. This achieves automated sequential operation of the opening and water supply actions of the outer cover 8 and inner cover 9 during the water supply process of the train's water tank, greatly improving the efficiency of water supply operations, reducing the labor intensity of operators, and effectively enhancing the intelligence level of the railway system.
