Description

Technical Field

[0001] This utility model relates to the field of loading and unloading arm flange connection technology, specifically an automated connection device for loading and unloading arm flanges. Background Technology

[0002] In the fields of petrochemicals and port transshipment, loading and unloading arms need to connect with containers such as storage tanks and tank trucks through flanges to transfer media. The sealing performance and efficiency of flange connections are directly related to production safety and pace. Traditional connection methods rely on manual operation, requiring multiple people to work together to complete flange alignment, bolt insertion and tightening. This is not only time-consuming and labor-intensive, but also prone to inaccurate flange alignment and uneven bolt torque due to operational deviations, increasing the risk of media leakage. Especially when handling toxic, flammable and explosive media, close-range manual operation also faces extremely high safety hazards.

[0003] With the increasing demands for industrial automation and intrinsic safety, the shortcomings of traditional manual methods have become increasingly apparent. Manual alignment of large flanges is difficult to control in terms of precision, and a single connection can take 15 to 30 minutes, which seriously restricts the efficiency of transfer. The bolt tightening torque depends on experience, which can easily damage the sealing surface or cause leakage. Existing semi-automatic tools still require manual intervention in key links and are only compatible with flanges of specific specifications, resulting in poor compatibility. Therefore, we propose an automated connection device for loading and unloading arm flanges. Utility Model Content

The top surface is provided with mounting holes 24, drive sliding holes 18 and detection mounting holes 27, which are used to fix the loading and unloading arm connecting platform 1, accommodate the transmission components and install the contact sensor 14, respectively. At the same time, it provides mounting support for the connecting guide components and the rotating clamping components, and is the integrated carrier of various functional components. Rotating support platform 5: A rectangular support platform 4 is fixed at equal intervals on the top surface of the connecting support platform 4. The rotating support rod 8 is fixed on the inner side to provide a rotation fulcrum for clamping the rotating rod 6, ensuring that the clamping rotating rod 6 can be stably rotated to clamp the flange when subjected to force. Clamping rotating rod 6: A rotating support hole 26 is opened on the bottom side, and a symmetrical adjustment sliding hole 25 is opened on the bottom outer side. The top and bottom surfaces can slide in contact with the flange 3. It is rotatably connected to the rotating support rod 8 through the rotating support hole 26. Under the drive of the transmission component, the flange is fixed by flipping and pressing the flange with the rotating support rod 8 as the fulcrum. Multiple sets of cooperation ensure that the flange is subjected to uniform force. Double-sided synchronous belt 7: The inner side can simultaneously engage the active synchronous pulley 23 and multiple sets of driven synchronous pulleys 20. It is installed on the top surface of the drive support platform 11 and transmits the power of the drive motor 21 to all driven synchronous pulleys 20 synchronously, ensuring that multiple sets of rotating threaded rods 19 rotate at the same speed, providing a power basis for uniform clamping. Rotating support rod 8: Fixed inside the rotating support platform 5, with both ends extending out and rotatably connected to the rotating support hole 26 of the clamping rotating rod 6, serving as the flipping fulcrum of the clamping rotating rod 6, and must have sufficient strength to withstand the clamping force; Guide support platform 9: A rectangular support platform 9 is fixed at equal intervals to the top surface of the connecting support platform 4. The top surface is fixed with guide slide 2. The guide slide 2 is installed horizontally and stably by its own height and strength, and the flange guiding accuracy is ensured. Motor mounting frame 10: Fixed to the bottom surface of drive support platform 11, the inner side accommodates and fixes drive connection motor 21, providing a stable installation space for the motor, while protecting the motor from external impact and ensuring stable motor operation; Drive support platform 11: The top surface has a rotating hole 22 and the bottom surface has a fixed motor mounting frame 10, which is used to support the rotating threaded rod 19 and connect the drive assembly, and provide an installation base for the bottom drive and transmission structure. It must have sufficient rigidity to resist vibration during power transmission. Clamping drive slide bar 12: It can slide vertically along the drive slide hole 18 of the connecting support platform 4. The top is fixedly connected to the rotating shaft 13 and the bottom is fixed to the threaded sleeve 17. It converts the rotational power of the rotating threaded rod 19 into vertical sliding displacement, thereby driving the clamping rotating rod 6 to flip. Connecting shaft 13: Fixed to the top of clamping drive slide bar 12, embedded in the adjusting slide hole 25 of clamping rotating rod 6 and slidable, serving as the connecting part between the two, converting the vertical displacement of the slide bar into the flipping force of clamping rotating rod 6; Contact sensor 14: Model CR-M01A, fixed in the detection mounting hole 27 of the connecting support platform 4, with the sensing end facing the flange 3 docking direction, detects the contact status between the external flange and the loading and unloading arm flange 3 in real time, sends an electrical signal to trigger the clamping process, and ensures that the clamping action is accurately started. Sealing ring 15: Fixed in the sealing groove 16 of the loading and unloading arm connecting platform 1, the material is mostly oil-resistant and corrosion-resistant rubber. When the flange is clamped, it is squeezed and deformed to fill the tiny gaps between the two flange contact surfaces, preventing media transfer and leakage. It is the core component of the sealing connection. Sealing groove 16: An annular groove formed on the top surface of the loading and unloading arm connecting platform 1, the size of which matches the sealing ring 15, is used to accommodate and fix the sealing ring 15, prevent the sealing ring from shifting during flange docking, ensure accurate sealing position, and improve sealing reliability. Threaded sleeve 17: A sleeve structure with internal threads on the inner side, fixed to the bottom surface of the clamping drive slide bar 12, and threadedly connected to the rotating threaded rod 19 on the inner side, converting the rotational motion of the rotating threaded rod 19 into its own vertical linear motion, thereby driving the clamping drive slide bar 12 to slide. Drive sliding hole 18: A rectangular or circular through hole opened on the top surface of the connecting support platform 4. The rectangular holes are evenly distributed and accommodate the clamping drive sliding rod 12 on the inside, allowing it to slide vertically. It guides the sliding trajectory of the sliding rod and prevents the sliding rod from deviating and affecting the clamping accuracy. Rotating threaded rod 19: The top is connected to the threaded sleeve 17 by a thread, and the bottom passes through the rotating hole 22 of the drive support table 11 and is fixed with the driven synchronous wheel 20. It rotates under the drive of the driven synchronous wheel 20 to provide power for clamping the drive slide rod 12. Driven synchronous pulley 20: It is fixedly sleeved on the outside of the rotating threaded rod 19 and meshes with the inner side of the double-sided synchronous belt 7. It rotates under the drive of the synchronous belt and drives the rotating threaded rod 19 to rotate. It needs to match the number of teeth of the driving synchronous pulley 23 to ensure stable transmission ratio. Drive connection motor 21: Fixed inside the motor mounting frame 10, with the output shaft fixed to the active synchronous wheel 23, can be started and output rotational power according to the control system signal, providing initial power for the entire clamping process, and must have stable speed and sufficient torque; Rotating hole 22: A circular through hole opened on the top surface of the drive support platform 11. The inner side accommodates the rotating threaded rod 19 and the driving synchronous wheel 23 and allows them to rotate. It limits the rotation trajectory of the rotating parts and ensures the coaxiality during power transmission. Active synchronous pulley 23: Fixed on the output shaft of the drive connection motor 21, meshing with the outer side of the double-sided synchronous belt 7, rotating with the output shaft of the motor and driving the driven synchronous pulley 20 through the synchronous belt, and is the starting component for power transmission; Mounting hole 24: A circular through hole opened on the top surface of the connecting support platform 4. The inner side is fixedly connected to the outer side of the loading and unloading arm connecting platform 1, such as by welding or bolting, to securely integrate the loading and unloading arm connecting platform 1 and the connecting support platform 4 and ensure that their relative positions are fixed. Adjustment sliding hole 25: A long strip-shaped through hole opened on the outer side of the bottom of the clamping rotating rod 6, symmetrically distributed, the inner side accommodates the connecting rotating shaft 13 and allows it to slide, providing displacement space for the connecting rotating shaft 13, ensuring that the clamping rotating rod 6 can be smoothly rotated, and avoiding motion interference; Rotation support hole 26: A circular through hole opened on the bottom side of the clamping rotation rod 6. The inner side is rotatably connected to the rotation support rod 8. It serves as the fulcrum for flipping the clamping rotation rod 6. The hole diameter must match the rotation support rod 8 to ensure smooth rotation without excessive gap. Detection mounting hole 27: A circular or rectangular hole opened on the top surface of the connecting support platform 4, the size of which matches the contact sensor 14, used to fix the sensor, ensure the accurate orientation of the sensor sensing end, and protect the sensor from external impacts, ensuring stable detection function; Working principle: When using this utility model, before starting the device, the flange 3 to be connected must be initially aligned with the loading and unloading arm connecting platform 1. At this time, the connecting guide assembly on the top surface of the connecting support platform 4 plays a role: the guide support platform 9 fixes and supports the guide slide 2, and the inclined guide surface on the top surface of the guide slide 2 can guide the flange 3 to slide along the preset trajectory, avoiding misalignment of the flange 3 due to positional deviation during docking, thus laying the foundation for subsequent clamping connection; at the same time, the sealing ring 15 in the sealing groove 16 on the top surface of the loading and unloading arm connecting platform 1 is in a state of waiting to be sealed, waiting for the flange to be fully docked to form a sealing structure. Once flange 3 is initially aligned, contact sensor 14 receives a signal and connects to the drive assembly to start power output: the drive motor 21 inside motor mounting frame 10 is energized and operates, its output shaft driving the active synchronous pulley 23 to rotate within the rotation hole 22 of drive support platform 11; the active synchronous pulley 23 transmits power synchronously to multiple driven synchronous pulleys 20 through meshing double-sided synchronous belts 7, thereby driving all rotating threaded rods 19 to rotate synchronously within the rotation hole 22. The rotational power of the rotating threaded rods 19 is converted into clamping action through the transmission assembly, and the rotating threaded rods 19 and the clamping... The threaded sleeve 17 on the bottom surface of the drive slide rod 12 forms a threaded engagement. When the threaded rod 19 rotates, the threaded sleeve 17 is limited by the drive sliding hole 18 and cannot rotate with the threaded rod. It can only slide vertically downward along the drive sliding hole 18, thereby driving the clamping drive slide rod 12 to move downward synchronously. The connecting shaft 13 at the top of the clamping drive slide rod 12 is embedded in the adjusting sliding hole 25 at the bottom of the clamping rotating rod 6. When the clamping drive slide rod 12 moves downward, the connecting shaft 13 slides in the adjusting sliding hole 25 and applies a downward pulling force to the clamping rotating rod 6. Since the clamping rotating rod 6 passes through the bottom... The rotating support hole 26 is rotatably connected to the rotating support rod 8 on the rotating support platform 5. Under the action of tension, the clamping rotating rod 6 rotates upward with the rotating support rod 8 as the fulcrum, and its top and bottom surfaces gradually fit against the top surface of the loading and unloading arm connecting platform 1. Finally, through multiple evenly distributed clamping rotating rods 6 applying pressure simultaneously, the mating flange 3 is firmly locked, completing the automated clamping and fixing. When it is necessary to disassemble the flange 3, the drive connecting motor 21 rotates in reverse. Through the reverse action of the above power transmission and transmission process, the clamping rotating rod 6 rotates downward to release the flange 3, and the disassembly can be completed.
