[0002] EMU, the full name of which is power vehicle, refers to vehicles equipped with power devices in rail transit systems, including locomotives and power cars. The widespread use of EMUs has not only shortened people's travel time and improved traffic conditions, but also promoted the prosperity of the regional economy and driven the innovation and development of related industries.

[0003] In actual applications, each time a train arrives at a terminal, it needs to be watered in order to replenish water resources for each carriage in order to meet the water demand of the train during long-term operation. However, the current water filling work of the train mainly relies on manual operation. When the train stops at a station, the water source is added to the train by manually dragging the water pipe. In this process, manual operation not only takes a long time, but also has a high labor intensity for manual labor. During the peak period of train travel, manual labor cannot continue to work for a long time. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0025] like Figure 1-Figure 4As shown, an automatic water filling inlet structure and a cover-opening water filling device for rail transit high-speed rail, the water filling inlet structure comprises a frame 2 mounted on a motor vehicle and arranged around the outer periphery of a water filling inlet 1, an inner cover 3 capable of flipping is hingedly connected to the water filling inlet 1, an outer cover 4 capable of flipping is slidably connected to the frame 2, a convex portion 301 is arranged on the inner cover 3, and a concave portion 401 is arranged on the outer cover 4;

[0026] The cover opening and water injection device comprises a rail RGV trolley 5 capable of traveling at a motor vehicle station and a cover opening and water injection mechanism, and a six-axis robot 6 is arranged on the rail RGV trolley 5;

[0027] The cover opening and water injection mechanism comprises a mounting base 7 connected to a six-axis robot 6, on which a floating joint assembly 8, a cover shifting fork 9 and a cover closing buckle plate 10 are arranged which can move axially along the floating joint assembly 8 respectively;

[0028] Both the convex portion 301 and the concave portion 401 can be snap-fitted with the cover shifting fork 9 and / or the cover closing buckle plate 10 .

[0029] Specifically, the water injection pipe is connected to the floating joint assembly 8, and the rail RGV trolley 5 is used to replace the manual dragging of the water injection pipe. The rail RGV trolley 5 can be a material trolley, etc., and can be driven by electric energy, motors, etc. to reduce the intensity of human labor. At the same time, after the rail RGV trolley 5 travels to the location of the water injection port 1 of the motor vehicle, the six-axis robot 6 can drive the mounting base 7 to move, and cooperate with the movable (i.e., telescopic movement relative to the mounting base 7) cover fork 9 and cover closing buckle plate 10 to engage with the convex part 301 on the inner cover 3 and the concave part 401 on the outer cover 4, and then move the outer cover 4 and the inner cover 3 of the water injection port 1 on the motor vehicle, so that the floating joint assembly 8 and the water injection port 1 are docked. The use of the cover opening and water injection mechanism in the present technical solution can greatly reduce the labor intensity of manual water injection, and at the same time can also improve the efficiency of water injection of the motor vehicle.

[0030] As described above, the cover-pushing fork 9 on the mounting base 7 can extend to the outside of the mounting base 7, and cooperate with the six-axis robot 6 to push the outer cover 4 and the inner cover 3 apart in sequence. Specifically, the cover-pushing fork 9 can smoothly push the outer cover 4 and the inner cover 3 at the water inlet 1 apart. Figure 4As shown, the cover fork 9 includes a first section 901 and a second section 902, the first section 901 and the second section 902 are connected to form a U-shaped structure, and a reinforcing rib 903 is arranged between the first section 901 and the second section 902, and a section connecting the first section 901 and the second section 902 is surrounded by the reinforcing rib 903 to form a closed loop structure, and the closed loop structure has a bending angle of 100° to 170°, so as to be clamped with the convex part 301 on the inner cover 3 and the concave part 401 on the outer cover 4. The reinforcing rib 903 can increase the strength of the closed loop structure on the cover fork 9, and the closed loop structure with a bending angle on the cover fork 9 can be clamped into the concave part 401 on the outer cover 4 and cover the convex part 301 on the inner cover 3, and the reinforcing rib 903 can also be against the back side of the convex part 301 to ensure that the cover fork 9 can be moved to clamp the inner cover 3 and the outer cover 4. At the same time, the floating joint assembly 8 gradually approaches until it docks with the water inlet 1. During this process, the cover fork 9 can gradually shrink toward the mounting base 7, which can effectively prevent the outer cover 4 or the inner cover 3 from accidentally hitting the floating joint assembly 8, thereby ensuring that the floating joint assembly 8 docks with the water inlet 1 smoothly.

[0031] Furthermore, after the motor vehicle is filled with water, the inner cover 3 and the outer cover 4 need to be reset. Figure 4 As shown, the closing buckle plate 10 includes a connecting plate 1001 and an L-shaped buckle plate 1002 arranged on the connecting plate 1001. One end of the L-shaped buckle plate 1002 can be snapped into the recess 401 on the outer cover 4. After the L-shaped buckle plate 1002 is snapped into the recess 401 on the outer cover 4, the six-axis robot 6 can drive the outer cover 4 to reset through the L-shaped buckle plate 1002.

[0032] In the present technical solution, in order to facilitate the resetting of the inner cover 3, a torsion spring can be provided on the axis where the inner cover 3 is hinged to the water injection port 1, so that the inner cover 3 can be actively reset to improve efficiency.

[0033] Further, such as Figure 4 As shown, the floating joint assembly 8 includes a metal tube 801 movably inserted on the mounting base 7, and one end of the metal tube 801 placed outside the mounting base 7 is provided with a quick connector 802 that can be plugged and connected with the motor vehicle water injection port 1, and a spring 803 sleeved on the outer periphery of the metal tube 801 is provided between the quick connector 802 and the mounting base 7. When the quick connector 802 is docked with the water injection port 1, the spring 803 can reduce the force between the quick connector 802 and the water injection port 1, prevent the quick connector 802 or the water injection port 1 from being compressed and deformed, and facilitate the six-axis robot 6 to make timely adjustments. In this technical solution, in order to prevent the floating joint assembly 8 from detaching from the mounting base 7, the two ends of the spring 803 can be connected to the mounting base 7 and the quick connector 802 respectively.

[0034] Furthermore, in the present technical solution, two cylinders 11 are provided on the mounting base 7, which are respectively connected to the cover shifting fork 9 and the cover closing buckle plate 10. By driving the cover shifting fork 9 and the cover closing buckle plate 10 by the cylinders 11, the displacement accuracy can be ensured and the manufacturing cost can be reduced.

[0035] In this embodiment, the rail RGV trolley 5 and the six-axis robot 6 are both existing and relatively mature technical means with higher stability, which can ensure the stability of the device operation. At the same time, they can also cooperate with the visual inspection module to accurately locate the positions of the inner cover 3 and the outer cover 4, so that the rail RGV trolley 5 and the six-axis robot 6 can automatically perform water injection operations, thereby further reducing manual labor and improving the efficiency of water injection for the motor vehicle.

[0036] Furthermore, a protective shell 12 is provided on the rail RGV trolley 5, and two protective doors 13 driven to open and close by hydraulic rods are provided on the protective shell 12. The protective shell 12 and the protective doors 13 are arranged to form a protective cover structure that can be arranged outside the six-axis robot 6. When the device is in the standby state, the six-axis robot 6, the mounting base 7, the cylinder 11, etc. are protected.

[0037] Working principle: The rail RGV trolley 5 replaces manual dragging of the water injection pipe to the water injection port 1 of the motor vehicle, and then the six-axis robot 6 drives the mounting base 7 to move, and then cooperates with the cover fork 9 that can perform telescopic movements relative to the mounting base 7, so that the outer cover 4 and the inner cover 3 at the water injection port 1 of the motor vehicle can be opened in sequence, and the quick connector 802 is docked with the water injection port 1 to perform water injection. After the water injection of the motor vehicle is completed, the six-axis robot 6 drives the mounting base 7 to move, unplug the quick connector 802 from the water injection port 1, and then drives the L-shaped buckle plate 1002 to engage with the recessed part 401 on the outer cover 4, and then drives the outer cover 4 to reset.

[0038] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
