Description

Technical Field

[0001] This invention relates to the field of gas cylinder testing technology, and more specifically, to a gas cylinder turning and drying device. Background Technology

[0002] Hydrogen cylinders are key containers for storing high-pressure hydrogen, widely used in fuel cell vehicles, industrial production, scientific research, and many other fields. As the global energy structure accelerates its transformation towards cleaner and lower-carbon energy sources, the importance of hydrogen energy in the overall energy system continues to rise. The market demand and application scope of hydrogen cylinders are expanding, and the corresponding hydrogen cylinder testing technology is rapidly developing towards intelligence and precision. Hydrogen cylinder testing is a crucial link in ensuring the safe application of hydrogen energy and is of great significance to promoting the high-quality development of the entire hydrogen energy industry.

[0003] Existing gas cylinder tilting and drying devices typically operate as follows: a conveyor transports the gas cylinder to the drying station, where stops position it to a preset location. Special clamps then hold the cylinder's mouth and body, and the operator uses a handwheel to adjust the position of the drying tube, aligning it and inserting it into the cylinder mouth. Finally, a drive mechanism rotates the clamps and cylinder together to complete a 90° tilt for drying. However, this type of device has significant shortcomings in practical use: firstly, it can only dry a single type of gas cylinder, failing to meet the needs of different cylinder sizes; secondly, manual adjustment of the drying tube alignment is required, preventing full automation of the entire process and impacting testing efficiency and operational consistency. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide a gas cylinder turning and drying device, which solves the technical problems that existing gas cylinder turning and drying devices cannot be compatible with multiple specifications of gas cylinders and cannot achieve fully automated drying throughout the process.

The clamping mechanism is used to cooperate with the conveyor roller to clamp the gas cylinder, and the clamping mechanism can be tilted vertically synchronously with the tilting frame. The drying tube has one end connected to a hot air source and the other end extended to the end of the conveyor roller. The drying tube can be inserted into the gas cylinder and deliver hot air into the gas cylinder.

[0009] Optional, also includes: The platform body, the flipping seat is disposed on the platform body, and the platform body has a groove for avoiding the flipping frame; The support frame has two supports, which are symmetrically arranged on both sides of the top of the platform. The support frame is used to support the tilting frame when it is in a horizontal state. The support frame includes a base mounted on the platform and a support rod hinged to the base. A third telescopic actuator is provided between the support rod and the flipping seat. The third telescopic actuator is used to push the support rod away from the flipping seat, so that the support rod swings vertically around the hinge, thereby canceling the support for the flipping frame and avoiding the flipping frame.

[0010] Optionally, one end of the third telescopic actuator is hinged to the support rod, and the other end is hinged to the flip seat, and the third telescopic actuator is arranged at an angle.

[0011] Optionally, a gas heater is provided on the platform, the drying pipe is connected to the gas heater, and a solenoid valve is provided on the drying pipe.

[0014] Optionally, the tilting frame is equipped with a sprocket and chain drive mechanism for driving the conical wheel assembly to rotate.

[0015] The beneficial effects of this invention are as follows: In this invention, gas cylinders are transported from a previous station to a conveyor roller on a tilting frame, which then moves the cylinders to a designated position. An adjustment mechanism adjusts the position of the drying tube according to the cylinder specifications, ensuring the tube is precisely aligned with the cylinder opening and inserted into the cylinder. A clamping mechanism then engages, working in conjunction with the conveyor roller to clamp and secure the cylinder. Subsequently, the tilting frame rotates vertically relative to the tilting base around its hinge axis, simultaneously tilting the cylinder, clamping mechanism, drying tube, and adjustment mechanism to a drying position. A hot air source delivers hot air into the cylinder through the drying tube, drying the interior. After drying, the tilting frame resets, the clamping mechanism releases, and the conveyor roller delivers the cylinder out. The vertical tilting of the cylinder by the tilting frame allows residual moisture to drain smoothly under gravity, improving drying effect and efficiency. The clamping mechanism, working in conjunction with the conveyor roller, stably holds the cylinder, ensuring reliable cylinder positioning during tilting and drying. The adjustment mechanism allows for flexible adjustment of the drying tube position, adapting to cylinders with different opening positions and expanding the device's applicability. The overall structure integrates conveying, clamping, flipping, and drying functions, with a smooth workflow that facilitates automated operation. Attached Figure Description

[0025] like Figures 1-7 The diagram illustrates a gas cylinder turning and drying device according to an embodiment of the present invention. The device includes a turning base 1, a turning frame 2, a conveyor roller 3, a clamping mechanism 4, a drying tube 5, and an adjusting mechanism 6. The turning frame 2 is hinged to the turning base 1 and can vertically turn relative to the turning base 1 around its hinge axis. The conveyor roller 3, used for conveying and supporting the gas cylinder 100, is mounted on the turning frame 2. The clamping mechanism 4 is mounted on the turning frame 2 and can cooperate with the conveyor roller 3 to clamp the gas cylinder 100, and can also vertically turn synchronously with the turning frame 2. One end of the drying tube 5 is connected to a hot air source, and the other end extends to the end of the conveyor roller 3, allowing it to be inserted into the gas cylinder 100 and deliver hot air into it. The adjusting mechanism 6 is located at the end of the turning frame 2 and can vertically turn synchronously with the turning frame 2. The end of the drying tube 5 near the conveyor roller 3 is mounted on the movable end of the adjusting mechanism 6, allowing the adjusting mechanism 6 to adjust the position of the drying tube 5 so that it aligns with the mouth of the gas cylinder 100.

[0026] In the above scheme, during operation, the gas cylinder 100 is conveyed from the preceding station to the conveyor roller 3 on the tilting frame 2, which transports the gas cylinder 100 to the set position. The adjustment mechanism 6 adjusts the position of the drying tube 5 according to the specifications of the gas cylinder 100, so that the drying tube 5 is accurately aligned with the mouth of the gas cylinder 100 and inserted into the cylinder. The clamping mechanism 4 operates, cooperating with the conveyor roller 3 to clamp and fix the gas cylinder 100. Subsequently, the tilting frame 2 rotates vertically relative to the tilting base 1 around the hinge axis, driving the gas cylinder 100, the clamping mechanism 4, the drying tube 5, and the adjustment mechanism 6 to rotate synchronously to the drying posture. The hot air source delivers hot air into the gas cylinder 100 through the drying tube 5 to dry the inside of the gas cylinder 100. After drying, the tilting frame 2 resets, the clamping mechanism 4 is released, and the conveyor roller 3 sends the gas cylinder 100 out. By tilting the gas cylinder 100 vertically through the tilting frame 2, the residual moisture inside the gas cylinder 100 can be smoothly discharged under the action of gravity, improving the drying effect and drying efficiency. The clamping mechanism 4, in conjunction with the conveyor roller 3, can stably clamp the gas cylinder 100, ensuring the reliable position of the gas cylinder 100 during the turning and drying process. The adjustment mechanism 6 can flexibly adjust the position of the drying tube 5 to adapt to gas cylinders 100 with different bottle opening positions, thus expanding the applicability of the device. The overall structure integrates conveying, clamping, turning, and drying functions, with a continuous operation process that facilitates automated operation.

[0027] Furthermore, the tilting frame 2 is provided with an inlet / outlet end 301 and a positioning end 302, and the adjustment mechanism 6 is installed on the positioning end 302 of the tilting frame 2. The adjustment mechanism 6 includes a mounting frame 61, a first telescopic driver 62, and a fixing member 63. The mounting frame 61 is fixed to the positioning end 302 of the tilting frame 2, the first telescopic driver 62 is vertically mounted on the mounting frame 61, and the fixing member 63 is located at the movable end of the first telescopic driver 62 and is used to fix the air outlet end of the drying tube 5. The fixing member 63 can move up and down with the movable end of the first telescopic driver 62, thereby driving the drying tube 5 to move so that the drying tube 5 is aligned with the mouth of the gas cylinder 100.

[0028] In the above scheme, after the information of gas cylinder 100 is entered, the device controls the first telescopic driver 62 to move according to the diameter parameter of gas cylinder 100. The movable end of the first telescopic driver 62 drives the fixing part 63 to move vertically up and down, and the fixing part 63 simultaneously drives the drying tube 5 to move up and down, adjusting the outlet end of the drying tube 5 to match the height of the gas cylinder 100. Gas cylinder 100 is fed in from the inlet / outlet end 301 and transported to the side of the positioning end 302. The drying tube 5 is accurately inserted into the gas cylinder 100 with the support of the fixing part 63, preparing for subsequent drying operations. The first telescopic driver 62 drives the fixing part 63 and the drying tube 5 to automatically adjust the height, replacing the traditional manual adjustment method, improving the alignment accuracy and adjustment efficiency of the drying tube 5. Setting the adjustment mechanism 6 at the positioning end 302 of the flipping frame 2 can ensure stable and reliable alignment between the drying tube 5 and the bottle mouth, avoiding misalignment during transportation and flipping. The vertical adjustment method is adapted to the bottle mouth height of gas cylinders 100 of different diameters, further improving the device's compatibility with multiple specifications of gas cylinders 100.

[0029] Furthermore, a particle counter 7 is installed on the mounting frame 61. The detection end of the particle counter 7 faces the docking position between the drying tube 5 and the mouth of the gas cylinder 100, which can sample the gas inside the gas cylinder 100 and realize the detection of particulate matter inside the gas cylinder 100.

[0030] In the above scheme, after the drying pipe 5 delivers hot air into the gas cylinder 100 to complete the drying operation, the device maintains the connection between the drying pipe 5 and the gas cylinder 100 and activates the particle counter 7. The particle counter 7 samples and analyzes the gas discharged from the gas cylinder 100 in real time, detects the particulate matter content in the gas, and determines whether the cleanliness of the gas cylinder 100 meets the standards. After the detection is completed, the particle counter 7 stops working, and the device performs a reset and discharge operation. The particulate matter detection function is directly integrated at the drying station, eliminating the need to transfer the gas cylinder 100 to other stations for separate detection, shortening the gas cylinder 100 detection process, and improving the overall detection efficiency. The particle counter 7 is installed on the mounting bracket 61 of the adjustment mechanism 6 and rotates synchronously with the flipping frame 2, allowing for immediate detection after drying. This ensures that the detection results accurately reflect the cleanliness state of the gas cylinder 100 after drying, meeting the requirements for cleanliness detection of the hydrogen cylinder 100.

[0031] Furthermore, the clamping mechanism 4 includes a fixed frame 41, a second telescopic actuator 42, a clamping plate 43, a photoelectric sensor 44, and a controller. The fixed frame 41 is mounted on the tilting frame 2, the second telescopic actuator 42 is vertically mounted on the fixed frame 41, and the clamping plate 43 is fixed to the movable end of the second telescopic actuator 42. The photoelectric sensor 44 is mounted on the fixed frame 41 and is used to detect the positioning information of the gas cylinder 100. The controller is also mounted on the fixed frame 41 and is electrically connected to both the photoelectric sensor 44 and the second telescopic actuator 42. It can control the second telescopic actuator 42 to perform telescopic actions based on the positioning information transmitted by the photoelectric sensor 44.

[0032] In the above scheme, when the gas cylinder 100 moves to the set position along the conveyor roller 3, the photoelectric sensor 44 detects the arrival signal of the gas cylinder 100 and transmits the signal to the controller in real time. After receiving the signal, the controller immediately controls the second telescopic driver 42 to extend downward. The second telescopic driver 42 drives the clamping plate 43 to move towards the gas cylinder 100, so that the clamping plate 43 cooperates with the conveyor roller 3 to firmly clamp the gas cylinder 100. After drying and inspection are completed, the controller controls the second telescopic driver 42 to retract upward, the clamping plate 43 separates from the gas cylinder 100, and the clamping state of the gas cylinder 100 is released. The automatic detection and automatic clamping of the gas cylinder 100 are achieved by the photoelectric sensor 44 and the controller, without manual intervention, improving the automation level of the device. The second telescopic driver 42 drives the clamping plate 43 to move, and the clamping force is stable and adjustable, which can be adapted to gas cylinders 100 of different diameters to ensure clamping reliability. The clamping mechanism 4 is installed on the tilting frame 2 and tilts synchronously with the tilting frame 2, without interfering with the tilting action, ensuring the stable operation of the device.

[0033] Furthermore, the device also includes a platform 8 and two support frames 9. The tilting seat 1 is fixedly mounted on the platform 8, and the platform 8 has a groove 81 for accommodating the tilting frame 2. The two support frames 9 are symmetrically arranged on both sides of the top of the platform 8 to support the tilting frame 2 in a horizontal position. Each support frame 9 includes a base 91 and a support rod 92. The base 91 is fixed to the platform 8, and the support rod 92 is hinged to the base 91. A third telescopic actuator 10 is provided between the support rod 92 and the tilting seat 1. The third telescopic actuator 10 can push the support rod 92 away from the tilting seat 1, causing the support rod 92 to swing vertically around the hinged position, thus removing the support for the tilting frame 2 and providing clearance space for the tilting frame 2.

[0034] In the above scheme, when the tilting frame 2 is in a horizontal state, the support rods 92 of the two support frames 9 support the tilting frame 2 from below, providing stable support for the tilting frame 2. When a tilting action is required, the third telescopic actuator 10 extends and pushes the support rods 92 away from the tilting seat 1. The support rods 92 swing upward around the hinge point on the base 91, disengaging from the tilting frame 2 and releasing the support for the tilting frame 2. The tilting frame 2 can then smoothly tilt downward into the groove 81 of the table body 8, completing the drying posture change. After drying is completed and the frame is reset, the third telescopic actuator 10 retracts, driving the support rods 92 to swing back to the support position, re-supporting the tilting frame 2.

[0035] The support frame 9 provides stable support for the tilting frame 2 during non-tilting phases, improving the operational safety and structural stability of the device. The third telescopic actuator 10 drives the support rod 92 to automatically swing and avoid obstacles, requiring no manual operation and ensuring smooth and continuous tilting motion. The groove 81 in the platform 8 provides ample clearance for the tilting frame 2, ensuring uninterrupted tilting motion and adapting to large-angle tilting requirements.

[0036] Furthermore, one end of the third telescopic actuator 10 is hinged to the support rod 92, and the other end is hinged to the flip seat 1. The third telescopic actuator 10 is arranged at an angle to provide a driving force in the tilting direction for the support rod 92.

[0037] In the above scheme, when the third telescopic actuator 10 extends, the inclined actuator applies an oblique thrust to the support rod 92, pushing the support rod 92 to swing upward around the hinge point. When the third telescopic actuator 10 retracts, it pulls the support rod 92 downward around the hinge point, restoring it to the supported position. The hinged connection ensures smooth and uninterrupted relative movement between the third telescopic actuator 10, the support rod 92, and the flipping seat 1. The inclined arrangement with hinges at both ends makes the transmission of driving force of the third telescopic actuator 10 more efficient, and the swing of the support rod 92 more stable. It avoids motion interference, ensures reliable extension and retraction of the support frame 9, and improves the operational stability and service life of the device.

[0038] Furthermore, a gas heater 11 is installed on the platform 8, and the drying pipe 5 is connected to the gas heater 11. A solenoid valve 12 is installed on the drying pipe 5, and the solenoid valve 12 is used to control the opening and closing of the hot air passage inside the drying pipe 5.

[0039] In the above scheme, the gas heater 11 is energized to heat the air to the set drying temperature. After the tilting frame 2 is tilted into place, the solenoid valve 12 opens, opening the internal passage of the drying pipe 5. The hot air generated by the gas heater 11 enters the gas cylinder 100 along the drying pipe 5 to dry the inside of the gas cylinder 100. After drying is completed, the solenoid valve 12 closes, cutting off the hot air supply, and the gas heater 11 stops working. The gas heater 11 can stably provide constant-temperature hot air, ensuring uniform and reliable drying results. The solenoid valve 12 realizes the automatic opening and closing of the hot air passage, facilitating precise control of the drying time and improving the consistency of the drying operation. The gas heater 11 is installed on the platform 8, with a reasonable layout that does not affect the tilting and conveying actions, and the overall structure of the device is compact.

[0040] Furthermore, a fourth telescopic actuator 13 is hingedly installed on the side wall of the groove 81 of the platform 8. The other end of the fourth telescopic actuator 13 is hingedly connected to the bottom of the flipping frame 2. The fourth telescopic actuator 13 drives the flipping frame 2 to flip and swing around the hinge axis through telescopic movement.

[0041] In the above scheme, when the drying process requires rotation, the fourth telescopic actuator 13 retracts, pulling the bottom of the rotating frame 2 downwards, causing the rotating frame 2 to rotate vertically relative to the rotating base 1 around the hinge axis to a set angle. After drying and inspection are completed, the fourth telescopic actuator 13 extends, pushing the bottom of the rotating frame 2 upwards, causing the rotating frame 2 to rotate in the opposite direction around the hinge axis, returning to a horizontal state. The limit switch on the rotating base 1 can detect whether the rotating frame 2 has rotated to the correct position. Using the fourth telescopic actuator 13 to drive the rotating frame 2 provides sufficient driving force, smooth operation, and precise control of the rotation angle. The hinged installation at both ends is compatible with the swing trajectory of the rotating frame 2, eliminating motion interference and ensuring reliable operation. It can achieve automatic rotation and automatic reset, improving the automation level of the device and meeting the continuous operation requirements of the 100 gas cylinder inspection line.

[0042] Furthermore, the conveyor roller 3 includes multiple spaced conical wheel sets 31, each conical wheel set 31 consisting of two symmetrically arranged conical wheels with their smaller diameter ends facing each other to form a centrally concave support structure.

[0043] In the above scheme, when the conical wheel assembly 31 rotates, the friction between the wheel surface and the outer wall of the gas cylinder 100 drives the gas cylinder 100 to move. The symmetrically arranged conical wheels with their smaller diameter ends facing each other can confine the gas cylinder 100 to the middle position of the wheel assembly, preventing lateral displacement of the gas cylinder 100 during conveying and flipping. Gas cylinders 100 of different diameters can be stably supported and guided when placed on the conical wheel assembly 31. The conical wheel assembly 31 is adaptable to supporting and conveying gas cylinders 100 of different diameters, exhibiting strong compatibility. The concave structure in the middle can automatically center and guide the gas cylinder 100, ensuring accurate alignment between the cylinder mouth and the drying tube 5. The spaced-out wheel assembly structure reduces the contact area with the gas cylinder 100, facilitating the dripping of residual moisture from the gas cylinder 100 surface and improving drying efficiency.

[0044] Furthermore, a sprocket and chain drive mechanism 14 is installed on the tilting frame 2. The sprocket and chain drive mechanism 14 is connected to each conical wheel group 31 for transmission and is used to drive the conical wheel group 31 to rotate synchronously.

[0045] In the above scheme, the sprocket and chain drive mechanism 14 is energized and transmits power to each conical wheel group 31 via the chain, driving all conical wheels to rotate synchronously in the same direction, realizing the automatic conveying and positioning of the gas cylinder 100. After the gas cylinder 100 is in place, the sprocket and chain drive mechanism 14 stops operating, keeping the conical wheel group 31 stationary. During discharge, the sprocket and chain drive mechanism 14 rotates in reverse, driving the conical wheel group 31 to rotate in the opposite direction, sending the gas cylinder 100 out of the drying station. The sprocket and chain drive mechanism 14 has stable transmission, ensuring that multiple conical wheel groups 31 operate synchronously, and the gas cylinder 100 is conveyed smoothly without jamming. The power transmission is reliable and suitable for conveying gas cylinders 100 of different weights, expanding the applicability of the lifting device. Integrated on the tilting frame 2, it moves synchronously with the tilting frame 2, without occupying additional space, and the device structure is compact and reasonable.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
