Abstract
Description
Technical Field
[0001] This invention relates to the field of storage and transportation equipment technology, and specifically to a support device for a Freon vertical tank. Background Technology
[0002] Freon vertical tanks (usually referring to Freon liquid receivers or gas-liquid separators) are critical pressure vessels in refrigeration systems used to store liquid refrigerant and ensure stable system operation. In the natural gas plant sector, these tanks are primarily used in auxiliary refrigeration systems using Freon (or its modern environmentally friendly alternatives such as HFCs) as the refrigerant. Their core functions include: liquid refrigerant storage and buffering: acting as a "reservoir," storing liquid Freon in the cycle and adjusting the liquid supply according to evaporator load changes to ensure a continuous and stable refrigerant supply; gas-liquid separation: acting as a separator before the compressor suction port to ensure that the refrigerant entering the compressor is a pure gas, preventing liquid refrigerant "liquid slugging" from damaging the compressor; system balancing and maintenance convenience: accommodating refrigerant recovered from other parts of the system during shutdown or maintenance, facilitating system maintenance and refrigerant management.
[0003] In processes employing mechanical refrigeration for deep dehydration or heavy hydrocarbon removal from natural gas, the Freon refrigeration system provides cooling to the heat exchanger, lowering the natural gas temperature. In this case, the Freon vertical tank serves as the core equipment for liquid storage and / or gas-liquid separation in this auxiliary refrigeration cycle. In the pre-cooling stage of some small LNG plants or large liquefaction processes, the Freon (or its alternatives) refrigeration cycle may be used as the pre-cooling stage. In such refrigeration subsystems, the vertical tank is responsible for liquid storage and ensuring the safe operation of the compressor.
[0004] These types of gas cylinders are characterized by their large weight, high center of gravity, and easily rolling cylindrical shape. In practical use, these cylinders require frequent handling, temporary securing, and connection to filling equipment. Currently, the common practice is to place the cylinders directly on the ground or on simple wooden / metal supports. Due to the lack of an effective securing structure, the cylinders are easily tipped over by external forces. The impact of tipping may cause the valve to break, leading to Freon leakage or even explosion. Freon is a greenhouse gas, and any leakage will cause ecological damage. Furthermore, the tipping of heavy objects and the leakage of cold air threaten the safety of operators. There is an urgent need for a safe and convenient Freon support device. Summary of the Invention
[0005] The purpose of this invention is to provide a support device for a Freon cylinder to solve the problem that, due to the lack of an effective fixing structure, the valve may break after the cylinder is tilted by external force, leading to Freon leakage or even explosion. In the event of a heavy object tipping over or cold air leakage, the safety of the operator will be threatened.
[0006] To achieve the above objectives, the basic solution provided by this invention is as follows: a support device for a Freon vertical tank, comprising a platform, with support rod 1 and support rod 2 at both ends of the platform. Support rod 1 and support rod 2 each have a strip-shaped groove, each groove containing a gear and a rack. A rotating frame is provided between support rod 1 and support rod 2, with rotating shafts at both ends of the rotating frame. The two rotating shafts are respectively fixedly connected to the gears in the two strip-shaped grooves. Both the upper and lower ends of the rotating frame have annular grooves, each groove containing several springs. Several annular blocks are connected to the springs, and several claws are hinged to the annular blocks. The upper end of the rotating frame is hinged to the right side of the rotating frame. A pressing component is provided at the upper end of the rotating frame, and a locking component is provided on the left side of the rotating frame. The upper end of the rotating frame and the left side are pressed together. A fixing unit is provided on the rotating frame. Four support legs are provided below the platform, each with a caster wheel.
[0007] The working principle of this invention is as follows: When the device is working, it first moves to a predetermined position via four support legs with universal wheels at the bottom. After the Freon canister is placed on the platform, it is supported by multiple spring-loaded annular blocks placed in the upper and lower annular grooves of the rotating frame. The springs provide buffering and adaptive clamping force. Several claws hinged on the annular blocks automatically retract inward under the action of the springs, adaptively gripping different parts of the canister and flipping the fixing unit. At the same time, the locking and pressing parts on the rotating frame engage to stabilize the Freon canister. Subsequently, the canister begins to rotate using its own weight. During the process, the gear is driven to rotate together. During its rotation, it rotates upward on the rack, raising the entire rotating frame and ensuring that the canister head will not touch the platform when rotating vertically.
[0008] The beneficial effects of this invention are as follows: the device is easy to move and initially position using outriggers with casters; it utilizes the principle of gears rotating and lifting on a rack to achieve rapid leveling and height adaptation of the platform, ensuring stable placement of the tank; its core rotating frame design allows the tank to rotate using its own weight, while the ring block with spring one and the self-adaptive claws can firmly and flexibly clamp the Freon tank, preventing slippage; the magnet of the stop lever two and the magnetic buckle of the rotating frame can effectively prevent the tank from rolling accidentally during transportation or operation; the design of the entire metal structure frame to prevent the tank from shaking reduces the risk of static sparks caused by friction or displacement, improving operational safety in flammable and explosive natural gas plant environments.
[0009] Option 2, a preferred option of the basic scheme, features a counterweight at the upper end of the rotating frame, and stop bars 3 on both support rod 1 and support rod 2, which abut against the rotating frame. The counterweight assists in the rotation of the upper end of the rotating frame and the entire structure, while the stop bars 3 limit the rotation of the frame, preventing excessive rotation and thus tilting of the tank.
[0010] Option 3, which is a preferred option of Option 2, includes a fixed unit comprising a first stop bar, a second stop bar, and a hinge. The first stop bar is fixedly connected to the rotating frame, and the rotating frame is hinged to the second stop bar. A connecting rod assembly is embedded in the side of the rotating frame that is hinged to the second stop bar, and the connecting rod assembly abuts against the upper end of the rotating frame. A magnet is provided at the end of the second stop bar away from the hinge, and a magnetic buckle is provided at the end of the rotating frame away from the hinge. The magnet and the magnetic buckle are magnetically connected. An iron wire is connected to the annular block at the lower end of the rotating frame, and the other end of the iron wire is fixedly connected to the second stop bar. After the Freon canister is placed in the center, the annular block is embedded. The wire pulls the second stop lever to rotate it, and the magnet at its end is magnetically locked into the magnetic buckle on the rotating frame. Together with the fixed stop lever, they form a barrier to prevent the canister from rolling. As the second stop lever closes, it drives the connecting rod assembly to exert an upward force on the upper end of the rotating frame. The upper end of the rotating frame rotates downward along the hinge using its own weight. Then, the locking part and the pressing part are connected. The upper end of the rotating frame and the counterweight increase the eccentric torque of the rotating frame through gravity, further assisting the rotation method of its own weight. The second stop lever provides rigid limit to the main body of the rotating frame. The dual effect significantly improves the stability of the canister clamping and the anti-tipping ability, effectively preventing accidental shaking or tipping caused by the shift of the center of gravity during operation.
[0011] Option 4, an optimal choice from Option 3, features a groove in the center of the platform containing halogen test paper. The halogen test paper passively absorbs leaked Freon refrigerant and undergoes a color reaction, enabling rapid, visual leak warnings and effectively improving the early detection capability of safety hazards in tank farms.
[0012] Option 5, a preferred embodiment of Option 4, comprises a connecting rod assembly including a wedge block, a second spring, a reset block, and a push rod. The wedge block abuts against the reset block. One end of the second spring is connected to the rotating frame, and the other end is connected to the reset block. The bottom of the push rod is wedge-shaped, and the push rod abuts perpendicularly against the wedge block. The push rod extends through one side of the rotating frame. When the second stop lever closes, it moves the wedge block inward. Simultaneously, the rising slope of the wedge block pushes the push rod upward. As the push rod rises, it pushes the upper end of the rotating frame to rotate along the hinge. Combined with the gravity of the counterweight, the locking and pressing parts connect, ultimately achieving the limiting of the tank. The overall structure is compact and reliable, precisely adapting to the usage requirements of the rotating frame.
[0013] Option 6, a preferred option of Option 5, features a ring on the rotating frame and a hook on the platform, with the hook detachably connected to the ring. This detachable connection provides physical restraint when not in operation, preventing accidental rotation of the rotating frame, while retaining the flexibility for quick separation, thus balancing operational safety and ease of maintenance.
[0014] Option 7, a preferred option of Option 6, features a hinged pull rod on one side of the platform. This pull rod is telescopic. Moving the entire device using the pull rod is less strenuous than manually bending over to push it, making the movement easier and faster.
[0015] Option 8, a preferred version of Option 7, involves applying an antistatic coating to the outriggers, platform, support rod 1, support rod 2, stop rod 1, stop rod 2, and stop rod 3. This antistatic coating forms a continuous conductive path on the surface of all critical metal components, instantly dissipating static charges generated by friction or displacement, completely eliminating the risk of electrostatic discharge igniting flammable gases, and ensuring inherent safety in flammable and explosive environments.
[0016] Option 9, a preferred option of Option 8, features an arc-shaped anti-slip rubber pad on the inner surface of each claw. This arc-shaped anti-slip rubber pad increases the coefficient of contact friction and adaptively presses against the can surface, providing strong anti-slip locking while buffering vibration and impact, effectively preventing the can from sliding within the claw or sustaining surface damage.
[0017] Option 10, a preferred option of Option 9, features an anti-static grounding terminal on one of the legs. This anti-static grounding terminal forms a permanent conductive path by connecting to an external grounding cable, directly conducting the accumulated static charge of the device to the ground, completely blocking the possibility of discharge sparks igniting leaked gas, and achieving intrinsic safety protection.

[0030] Example
[0031] The basic implementation examples are as follows: Figure 1 To be continued Figure 10 As shown: A support device for a Freon vertical tank includes a platform 1.

Each support rod 1 2 and support rod 2 3 has a strip groove 4. Each strip groove 4 is provided with a gear 5 and a rack 6. A rotating frame 13 is provided between support rod 1 2 and support rod 2 3. The two ends of the rotating frame 13 are provided with rotating shafts 14. The two rotating shafts 14 are respectively fixedly connected to the gears 5 in the two strip grooves 4.
[0032] Both the upper and lower ends of the rotating frame 13 are provided with annular grooves 35. Each annular groove 35 is provided with several springs 15. Annular blocks 16 are connected to the springs 15. Several claws 17 are hinged to the annular blocks 16. The inner surface of each claw 17 is provided with an arc-shaped anti-slip rubber pad 33. The upper end of the rotating frame 13 is hinged to the right side of the rotating frame 13. A pressing part 7 is provided at the upper end of the rotating frame 13. A locking part 32 is provided on the left side of the rotating frame 13. The upper end of the rotating frame 13 is pressed and locked to the left side. A fixing component is provided on the rotating frame 13.
[0033] The fixing assembly includes a first stop bar 18, a second stop bar 19, and a hinge 20. The first stop bar 18 is fixedly connected to the rotating frame 13. The rotating frame 13 is hinged to the second stop bar 19 via the hinge 20. A wire 27 is connected to the annular block 16 at the lower end of the rotating frame 13. The other end of the wire 27 is fixedly connected to the second stop bar 19. A connecting rod assembly is embedded in the side of the rotating frame 13 that is hinged to the second stop bar 19. The connecting rod assembly abuts against the upper end of the rotating frame 13.
[0034] The linkage assembly includes a wedge block 8, a second spring 9, a reset block 10, and a push rod 11. The wedge block 8 abuts against the reset block 10. One end of the second spring 9 is connected to the rotating frame 13, and the other end is connected to the reset block 10. The bottom of the push rod 11 is wedge-shaped, and the push rod 11 abuts against the wedge block 8 perpendicularly. The push rod 11 moves through one side of the rotating frame 13. The end of the second stop rod 19 away from the hinge 20 is provided with a magnet 21, and the end of the rotating frame 13 away from the hinge 20 is provided with a magnetic buckle 22. The magnet 21 and the magnetic buckle 22 are magnetically connected.
[0035] The upper end of the rotating frame 13 is provided with a counterweight 25. Both support rod 1 2 and support rod 2 3 are provided with a stop bar 3 26, which abuts against the rotating frame 13. The rotating frame 13 is provided with a ring 30, and the platform 1 is provided with a hook 31. The hook 31 is detachably connected to the ring 30. There are four support legs 23 under the platform 1. The support legs 23 are provided with an anti-static grounding terminal 34. Each support leg 23 is provided with a caster wheel 24. A pull rod 12 is hinged to one side of the platform 1.
[0036] The pull rod 12 is a telescopic structure, which can be one of the following: rotary thread telescopic (such as the screw rod of a mechanical jack), multi-section nested telescopic (such as a camera tripod), or snap-lock positioning telescopic (such as an adjustable mop handle). The support leg 23, platform 1, support rod one 2, support rod two 3, stop rod one 18, stop rod two 19, and stop rod three 26 are all coated with an anti-static coating.
[0037] The implementation method of this embodiment is as follows:
[0038] When using the device, first push or pull the lever 12, and move the device to the target work position via the casters 24 at the bottom of the four legs 23.
[0039] First, the Freon can is placed vertically at the bottom of the rotating frame 13. The annular block 16 will sink under the weight of the can. The claws 17 on the annular block 16 hold the can body through leverage. The arc-shaped anti-slip rubber pad 33 is pressed against the can wall to prevent slippage. As the annular block 16 sinks, the wire 27 is pulled downward. At the same time, the wire 27 pulls the stop lever 29 inward. The hinge 20 on the stop lever 29 is pulled inward quickly after being pulled, causing the stop lever 29 to rotate quickly and lock the magnet 21 into the magnetic buckle 22, thus limiting the position of the can.
[0040] While the second stop lever 19 rotates, the wedge block 8 is pushed into the interior of the rotating frame 13. As the wedge block 8 is pushed in, the top rod 11 is lifted by the inclined surface of the raised wedge block 8, applying an upward thrust to the hinge at the upper end of the rotating frame 13, causing the upper end of the rotating frame 13 to rotate along the hinge. The weight of the counterweight 25 is used to lock the pressing part 7 and the locking part 32. Then, the hook 31 and the ring 30 are released. While the rotating frame 13 rotates by its own weight, the counterweight 25 at the upper end provides a gravitational torque, driving the entire rotating frame 13 together with the fixed Freon tank to start rotating around the two rotating shafts 14. Through the cooperation of the gear 5 and the rack 6 on the rotating shaft 14, it rises to a certain height while rotating, preventing the head of the Freon tank from touching the platform 1 after rotation. When the rotating frame 13 drives the tank to rotate 180° completely with the head facing down, the main body of the rotating frame 13 is rigidly stopped and limited by the third stop lever 26 on the two side support rods.
[0041] Throughout the process, the antistatic coating on the surfaces of metal components such as outriggers 23, platform 1, brackets, and stop bars, as well as the antistatic grounding terminal 34, ensure that static charge is safely conducted to the ground, while the halogen test paper 29 in the groove 28 continuously monitors for possible leaks at the can opening.
[0042] After the Freon canister is empty, first disconnect the gas tube from the Freon canister. Then, rotate the rotating frame 13 180° to reset it. After the rotating frame 13 is against the stop lever 26, hang the hook 31 on the upper limit of the ring 30. Then, open the stop lever 19 and press the upper end of the rotating frame 13 to separate the pressing part 7 and the locking part 32, releasing the limit on the Freon canister. At this time, because the weight of the Freon canister is reduced, the spring 15 pushes the ring block 16 upward. The pawl 17, no longer pressed down by gravity, gradually returns to its original position, releasing the canister. Then, take out the empty Freon canister. Finally, put the device back into place in the auxiliary rack storage area after returning it to its original position via the casters.
