[0002] A hydrogen refueling station is a gas station that provides hydrogen to fuel cell vehicles. The earliest hydrogen refueling station can perhaps be traced back to the 1980s at Los Alamos in the United States. As an infrastructure for providing hydrogen to fuel cell vehicles, the number of hydrogen refueling stations is also growing, and various demonstration activities are being carried out around the world. The construction and demonstration operation of these hydrogen refueling stations have accumulated a lot of data and experience for the future.

[0026] 1. The present invention can ensure the accuracy of the position between the vertically distributed driving components and the main frame. The driving components can drive the walking wheels to drive the entire lifting device. The hydrogen cylinder on the upper end of the loading mechanism can be lifted and loaded in conjunction with the hook. When the device is lifting, the hydraulic feet on both sides of the driving components are supported by the ground to ensure the maximum stability of the device during the process of lifting the hydrogen cylinder and avoid displacement. After the lifting work is completed, the hydrogen cylinder is moved and loaded by driving the walking wheels.

[0027] 2. The present invention can improve the firmness of the entire main frame by arranging reinforcing diagonal bars on both sides of the main frame, avoid the main frame from tilting and shaking during the process of lifting the hydrogen cylinder, and ensure the safety of the entire device during actual use. The obtuse-angled distribution of the reinforcing diagonal bars and the main frame makes the force on the reinforcing diagonal bars more uniform. The four reinforcing diagonal bars and the main frame cooperate with each other to form a frame structure, which makes the main frame more stable during lifting.

[0028] 3. The present invention arranges a limit inner rod on the outside of the rope, which cooperates with the limit outer rod connected to the outside of the limit inner rod. The sliding structure enables the limit inner rod to slide downward inside the limit outer rod under the action of its own gravity, and the lower end of the limit inner rod is inserted into the limit circular groove on the upper end of the connecting block, so that the extension and contraction between the limit inner rod and the limit outer rod is consistent with the extension and contraction of the rope, which can effectively prevent the hydrogen bottle from tilting and swaying during the process of lifting the hydrogen bottle through the hook, thereby ensuring the safety of the hydrogen bottle during the lifting process. At the same time, the limit sliding block arranged on the outside of the limit inner rod, in cooperation with the limit sliding groove arranged on the inside of the limit outer rod, can have a good limiting effect on the limit inner rod, thereby preventing the limit inner rod from rotating during the extension and contraction process.

[0029] 4. The present invention can ensure the accuracy of the positions between the connecting blocks, receiving plates and large-scale weighing instruments distributed in parallel. The total weight of the lifted hydrogen cylinders can be weighed by vertically adjusting the large-scale weighing instrument. The weight will be displayed on the upper end of the display screen arranged at the front end of the large-scale weighing instrument for easy viewing, thereby avoiding damage to the lifting device due to overweight and causing safety hazards. While ensuring the continuity and effectiveness of the lifting device, the actual service life of the device is improved.

[0030] 5. The present invention can provide good protection for the lifting winch by setting a protective cover on the upper end of the main frame, avoiding corrosion damage to the lifting winch caused by long-term outdoor work. At the same time, the heat dissipation ports arranged on both sides of the protective cover cooperate with the cooling fan to form convection of air inside the protective cover, which can provide good heat dissipation effect for the lifting winch in the working state and ensure the continuity and effectiveness of the lifting winch's operation. The dust cover connected to the heat dissipation port by tightening bolts is easy to disassemble and clean, thereby ensuring the heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS
