[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0042] Reference Figures 1 to 11 As shown, an embodiment of the present invention provides a hydrogen exchange system for a hydrogen exchange station, including: a ceiling-mounted robot 1000 for a hydrogen exchange station, a frame 2000 and a beam 3000 .

[0043] The ceiling-mounted robot 1000 for a hydrogen exchange station includes a main body 100, a first moving assembly 200, a lifting drive assembly 300, and four pulley assemblies 400. The first moving assembly 200 includes a moving wheel assembly 210 disposed on either side of the main body 100. The moving wheel assembly 210 includes a driving wheel 211 and a driven wheel 212 rotatably connected to the ends of the main body 100. The driving wheel 211 is powered. The moving wheel assembly 210 is configured to drive the robot in the X-direction. The lifting drive assembly 300 includes a lifting power unit 310, a drum 320 connected to the output end of the lifting power unit 310, and a wire rope 330 wound around the drum 320. The lifting power unit 310 may be a motor. The drum 320 is rotatably connected to the main body 100. There are four wire ropes 330, one at each of the four corners of the main body 100. The four pulley assemblies 400 are rotatably connected to the main body 100 . The pulley assemblies 400 are arranged in a one-to-one correspondence with the steel wire ropes 330 . The free ends of the steel wire ropes 330 pass through the pulley assemblies 400 and are connected to the sling 4000 .

[0044] The beam 3000 is slidingly connected to the frame 2000 through the second movable component 5000, and the second movable component 5000 is configured to drive the beam 3000 to move along the Y direction on the frame 2000; two tracks extending along the X direction are provided on the beam 3000, and the robot's moving wheel group 210 is arranged in a one-to-one correspondence with the tracks, and the driving wheel 211 and the driven wheel 212 of the moving wheel group 210 are respectively rollingly connected to the tracks.

[0045] Specifically, the ceiling-mounted robot 1000 of this application can move in both the X and Y directions, thereby efficiently lifting and replacing the hydrogen storage tank 6000 in conjunction with the hoist 4000, saving time and effort. Furthermore, the ceiling-mounted robot 1000 of this application has a simple structural design, is low-cost, and is easy to maintain. Therefore, this application can improve the efficiency of hydrogen exchange stations and solve the problem of long refueling times at traditional hydrogen refueling stations.

[0046] Furthermore, the first moving assembly 200 also includes a moving drive unit 220 (e.g., a motor). Both first moving assemblies 200 share a single moving drive unit 220. The output shaft of the moving drive unit 220 is connected to the driving wheel 211. Specifically, a connecting plate 230 is connected to the main body 100, and the moving drive unit 220 is connected to the main body 100 via the connecting plate 230. The output shaft of the moving drive unit 220 is rotatably connected to the connecting plate 230 via a bearing and then coaxially connected to the driving wheel 211. The moving drive unit 220 drives the driving wheel 211, thereby rotating it and causing the driven wheel 212 to rotate with it, thereby driving the robot back and forth on the beam 3000. Specifically, in this embodiment, the two first moving assemblies 200 share a single moving drive unit 220, allowing the two moving wheel assemblies 210 to operate synchronously, ensuring smooth movement of the ceiling-mounted robot 1000. This simple structure reduces manufacturing costs and saves energy.

[0047] Furthermore, there are two drums 320, and the two wire ropes 330 share one drum 320. The lift drive assembly 300 also includes two bearing blocks 340, which are positioned corresponding to the drums 320 and are bolted to the main body 100. The bearing blocks 340 are welded components. One end of the drum 320 is rotatably connected to the bearing block 340 via a bearing, and the other end of the drum 320 is connected to the output shaft of the lift power unit 310. Specifically, in this embodiment, the two wire ropes 330 share one drum 320, reducing costs.

[0048] Furthermore, there is one lifting power unit 310, which is connected to two drums 320. Specifically, in this embodiment, the two drums 320 share one lifting power unit 310, which reduces costs while ensuring that the four steel ropes 330 are raised and lowered synchronously.

[0049] In this application, the lifting power unit 310 drives the two drums 320 to rotate synchronously, so that the four steel ropes 330 are synchronously extended and retracted to lift the sling 4000 and the hydrogen storage tank 6000 up and down smoothly.

[0050] In some comparative embodiments, when a hydrogen exchange station uses a wire rope 330 in conjunction with a pulley 420 to lift a hydrogen storage tank 6000, when the hoist 4000 has contacted the outer frame of the hydrogen storage tank 6000, the wire rope 330 needs to be loosened to ensure good contact between the hoist 4000 and the hydrogen storage tank 6000. This can lead to unstable movement and shortened service life, so a mechanism is required to tighten the wire rope 330.

[0051] Furthermore, to address the issues described in the comparative embodiment, the pulley assembly 400 includes a bracket 410, a pulley 420 with a groove, a pressure roller 430, and an elastic member 440 (e.g., a spring). The bracket 410 is connected to the main body 100 and moves up and down relative to the main body 100. The pulley 420 is rotatably connected to the bracket 410. The pressure roller 430 is rotatably connected to the bracket 410. One end of the elastic member 440 is connected to the pressure roller 430 and the other end is connected to the bracket 410. The pressure roller 430 is located in the groove and elastically drives the pressure roller 430 to compress the wire rope 330 wound around the groove of the pulley 420. The bracket 410 is welded together by a base plate 411, a vertical plate 412, and a reinforcing plate 413. The pulley assembly 400 also includes a rotating plate 414, one end of which is rotatably connected to the top of the bracket 410 via an upper rotating shaft 460. The pressure roller 430 is rotatably connected to the other end of the rotating plate 414 via a lower rotating shaft 470. The pulley 420 is rotatably connected to the bracket 410 via a rotating shaft, which is equipped with an overload sensor 480. Stoppers 490 are provided on either side of the bracket 410, which cooperate with the rotating shaft to secure it. Specifically, in this embodiment, the elastic member 440 is stretched to generate tension, causing the pressure wheel 430 to press against the wire rope 330. This effectively prevents the wire rope 330 from becoming too loose, resulting in unstable movement and reduced service life.

[0052] Furthermore, pulley assembly 400 includes a spring plate 450 disposed on one side of bracket 410. Spring plate 450 is provided with multiple holes 451 (e.g., five holes 451). The ends of elastic member 440 are connected to different holes 451, with each hole 451 positioned at different distances from the other end of elastic member 440. Specifically, the desired spring tension position, i.e., the connection of elastic member 440 to different holes 451, can be selected based on the workload. This indicates that the tension of elastic member 440 in this embodiment is adjustable, adapting to varying workloads and embracing a wide range of applications.

[0053] Furthermore, the present application includes a drag chain 500 disposed on one side of the main body 100. The crossbeam 3000 is provided with a mounting slot, and the drag chain 500 is mounted in the mounting slot. The cables of the lifting power unit 310 and the mobile drive unit 220 are installed in the drag chain 500. A drag chain bracket 110 is connected to one side of the main body 100, and the drag chain bracket 110 is connected to one end of the drag chain 500. Specifically, the drag chain 500 provided in this embodiment can protect the cables. Therefore, when the first moving assembly 200 drives the robot to move, one end of the drag chain 500 moves synchronously, thereby protecting the cables and preventing damage.

[0054] Furthermore, the present application also includes a distance measurement assembly 7000 for measuring the distance the robot travels in the X-direction. The distance measurement assembly 7000 includes a distance measurement receiver and a distance measurement transmitter electrically connected to the distance measurement receiver. The transmitter is connected to the crossbeam 3000, and the distance measurement transmitter is located on the side of the main body 100 facing the distance measurement receiver. Specifically, this embodiment uses the distance measurement receiver and the distance measurement transmitter to monitor the robot's distance traveled in the X-direction in real time. This facilitates docking of the sling 4000 with the hydrogen storage tank 6000.

[0055] Furthermore, the present application further includes a top cover 120 connected to the top of the main body 100. Specifically, the top cover 120 can shield and protect other components of the present application.

[0056] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
