[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] like Figure 1 As shown, an embodiment of this utility model provides a steel cylinder transportation device, including a transport vehicle, a steel cylinder storage container 4, a flange door 5, and a valve electric assist mechanism 6. The transport vehicle is used to transport steel cylinders, the steel cylinder storage container 4 is mounted on the transport vehicle and is used to store steel cylinders, the flange door 5 is rotatably mounted on the transport vehicle and is used to seal the opening of the steel cylinder storage container 4, and the valve electric assist mechanism 6 is installed on the flange door 5 and can drive the valve of the steel cylinder inside the steel cylinder storage container 4 to open or close.

[0031] When transporting the gas cylinders, first open flange 5, place the cylinder into storage container 4, and then close flange 5 to seal the cylinder within storage container 4, preventing leakage of the medium inside. The cylinder valve is opened or closed by an electric valve-assisted mechanism 6, eliminating the need for operators to manually tighten the valve with a wrench, saving labor costs, reducing work difficulty, and significantly improving work efficiency.

[0032] Specifically, drive wheel 3 is a hub motor drive wheel, which is configured with a front-to-rear diagonal differential drive structure. When the left front wheel and the right rear wheel rotate in the forward direction at the same time, and the right front wheel and the left rear wheel rotate in the opposite direction at the same time, the torque generated by the four wheels forms a resultant torque at the center point of the vehicle, causing the transport vehicle to rotate around its own geometric center, thus realizing a 360° turn on the spot.

[0033] Optionally, the maximum speed of the transport vehicle is 6 km / h.

[0034] Optionally, battery pack 2 uses a lithium iron phosphate battery module and is equipped with a battery level indicator.

[0035] Optionally, the water capacity of the cylinder storage container 4 is 50L, which can be adapted to cylinders of different capacities.

[0036] Specifically, the cylinder storage container 4 is cylindrical and made of carbon steel. Stainless steel or nickel-plated steel can also be used if there are special requirements.

[0037] Furthermore, the valve electric assist mechanism 6 includes a servo motor 61, a reduction gearbox 62, and a telescopic component. The output end of the servo motor 61 is fixedly connected to the input end of the reduction gearbox 62, and the output end of the reduction gearbox 62 is fixedly connected to the telescopic component. A sleeve is fixedly connected to the output end of the telescopic component. The telescopic component can extend and retract along the axial direction of the cylinder storage container 4 so that the inner wall of the sleeve is relatively fixed to the outer wall of the cylinder valve.

[0038] Place the gas cylinder in the gas cylinder storage container 4, ensuring the cylinder is fixed in position and the valve is in a suitable operating state. Simultaneously, adjust the valve electric assist mechanism 6 to its initial position, ensuring the telescopic component is not extended and the sleeve maintains a certain distance from the gas cylinder valve. After adjustment, extend the output end of the telescopic component along the axial direction of the gas cylinder storage container 4, allowing the sleeve to engage with the gas cylinder valve. At this point, the sleeve and the gas cylinder valve are tightly connected, preparing for subsequent opening or closing operations. Then, start the servo motor 61. The servo motor 61 begins operation and outputs power, which is transmitted to the reduction gearbox 62. The reduction gearbox 62 converts the high-speed, low-torque output of the servo motor 61 into a low-speed, high-torque output to meet the torque required for valve operation. The servo motor 61 transmits torque through the reduction gearbox 62 and the telescopic component, thereby enabling the sleeve to open or close the gas cylinder valve. During operation, the direction and speed of the servo motor 61 can be controlled according to actual needs to precisely control the degree of valve opening or closing. After the valve operation is completed, the servo motor 61 is turned off, and the telescopic component is retracted along the axial direction of the gas cylinder storage container 4, so that the sleeve is separated from the gas cylinder valve. The valve electric assist mechanism 6 returns to the initial position and waits for the next operation.

[0039] Optionally, the telescopic component can be an electric push rod or a telescopic cylinder, etc. Using a telescopic component allows it to accommodate gas cylinders of different heights. Specifically, the telescopic stroke of the component is 0-300mm.

[0040] It should be noted that the forward rotation of the servo motor 61 can drive the sleeve to close the cylinder valve, and the reverse rotation of the servo motor 61 can drive the sleeve to open the cylinder valve.

[0041] Furthermore, the sleeve has built-in elastic grippers that can automatically adapt to the external hexagonal of commonly used bottle valves of different specifications and sizes.

[0042] Furthermore, the cylinder transport device also includes a display screen mounted on the frame 1, which displays the speed of the frame 1, the charge level of the battery pack 2, and the torque of the servo motor 61.

[0043] This setup allows for reasonable speed control and timely monitoring of battery pack 2's charge level, enabling operators to plan transportation routes effectively. If the charge is low, charging can be arranged in advance to prevent the transport vehicle from running out of power during transport, thus ensuring timely delivery of the cylinders. The display screen shows the torque of the servo motor 61, allowing operators to monitor the torque required for valve opening and closing in real time. Precise control of the servo motor 61's torque output, based on the cylinder valve's requirements, prevents damage to the valve due to excessive torque or incomplete opening or closing due to insufficient torque, ensuring the accuracy and safety of cylinder valve operation.

[0044] Important information such as frame speed, battery charge, and servo motor torque are displayed on the screen, eliminating the need for operators to view different instruments or devices separately. They can obtain comprehensive information from a single interface, improving operational convenience and efficiency.

[0045] Furthermore, the transport vehicle includes a frame 1, a battery pack 2 mounted on the frame 1, and a plurality of drive wheels 3 mounted on the frame 1. The battery pack 2 can provide power to the plurality of drive wheels 3 so that the plurality of drive wheels 3 rotate and drive the frame 1 to move.

[0046] Specifically, the transport vehicle is an electric-assisted transport vehicle. Compared to existing cylinder transport vehicles on the market that rely on manual pushing, the electric-assisted transport vehicle is not only more efficient, but also requires no two people to work together for each operation, reducing labor intensity. Especially in work environments that require long-distance transport or frequent cylinder handling, operators do not need to expend a lot of physical strength and time, thus greatly improving work efficiency and the timeliness of transport.

[0047] Furthermore, the frame 1 is equipped with a forklift slot to accommodate the forks of a forklift. This arrangement facilitates the transport of the entire cylinder transport device to a designated area, making loading and unloading convenient.

[0048] Furthermore, the cylinder storage container 4 is equipped with a lifting ring 7, which is used by a lifting device to lift the cylinder storage container 4. This design facilitates the lifting or transport of the cylinder storage container 4 to the frame 1, making loading and unloading convenient.

[0049] The aforementioned transport vehicle is equipped with brakes, and the front wheel of the transport vehicle is equipped with a first handrail 10, and the rear wheel is equipped with a second handrail 11. The brake handle is located at the first handrail 10, which facilitates braking during the movement of the transport vehicle.

[0050] Furthermore, the gas cylinder storage container 4 is equipped with a pressure gauge 8, which is used to display the pressure value inside the gas cylinder storage container 4. This configuration allows for timely display of pressure changes inside the gas cylinder storage container 4, and the pressure changes can be used to predict whether a gas cylinder leak has occurred. If the pressure value is too high, it indicates that the gas cylinder is leaking, and remedial measures can be taken in time.

[0051] Furthermore, the cylinder storage container 4 is equipped with a top-mounted valve 9. The inlet end of the top-mounted valve 9 is used to connect with the storage container filled with inert gas, and the outlet end of the top-mounted valve 9 is connected with the cylinder storage container 4.

[0052] Inert gas is introduced into the cylinder storage container 4 via the top-loading valve 9, displacing harmful gases and reducing the possibility of combustion, explosion, or other hazardous reactions within the container, thus ensuring the safety of cylinder storage and transportation. If a gas leak occurs, the introduced inert gas can dilute the leaked gas, reducing its concentration within the container and decreasing the probability of danger. Simultaneously, the inert gas also acts as a pressure buffer, preventing a rapid increase in pressure within the container.

[0053] Furthermore, the cylinder transport device also includes a wireless remote controller, which is connected to the battery pack 2 and is used to control the start and stop of the transport vehicle.

[0054] Operators can remotely control the start and stop of the transport vehicle using a wireless remote control, which improves the ease of operation and the safety of the operation.

[0055] Furthermore, the cylinder transport device also includes an emergency stop button, which can cut off the circuit between the battery pack 2 and multiple drive wheels 3 to stop the transport vehicle. In case of an emergency, pressing the emergency stop button cuts off the main circuit, thereby achieving an emergency stop of the transport vehicle and improving the safety performance of the entire device.

[0056] The gas cylinder transport device also includes a controller. The hub motor drive wheel, servo motor 61, and wireless remote controller are all connected to the controller. When the valve opening torque reaches the set value and the angle reaches 90°, the servo motor 61 transmits a signal to the controller, which then de-energizes the hub motor drive wheel, causing the transport vehicle to stop automatically. The wireless remote controller transmits signals for starting and stopping the transport vehicle and opening and closing the gas cylinder valve to the controller, which then controls the starting and stopping of the transport vehicle and the opening and closing of the gas cylinder valve.

[0057] It should be noted that if the wireless remote control loses connection with the controller for more than 2 seconds, the transport vehicle can automatically brake. When the hub motor and servo motor 61 exceed the preset current safety threshold, the system automatically cuts off the output and enters the protection state, thereby automatically stopping the machine. All of the above are existing technologies in this field, similar to wireless remote control toy cars, and will not be described in detail here.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
