Description
Technical Field
[0001] This utility model belongs to the field of shelving technology, and specifically relates to a liquefied gas cylinder stacking rack. Background Technology
[0002] As a commonly used gas storage container, the safe stacking and convenient management of liquefied petroleum gas (LPG) cylinders are critical requirements in warehousing, transportation, and use. Currently, most LPG cylinder stacking racks on the market adopt a fixed structure design, which has the following main technical defects:
[0003] First, there is insufficient safety and stability. Traditional stacking racks typically use simple limiting blocks, grooves, or straps to fix gas cylinders. When the stacking rack tilts due to handling, transportation, or external vibrations, the gas cylinders are prone to sliding or even tipping over due to the shift in the center of gravity, posing safety hazards such as cylinder collisions and gas leaks. Furthermore, the fixed limiting structure cannot be dynamically adjusted according to the actual position of the gas cylinder, resulting in limited limiting effectiveness.
[0004] Secondly, space utilization is low. The number of layers and the spacing between layers of existing stacking racks are mostly fixed designs, making it difficult to flexibly adjust according to the site space or the number of cylinders. Especially in storage or transportation scenarios with limited vertical space, it is impossible to compactly stack multiple layers of cylinders through tilting or linkage structures, resulting in a waste of space resources.
[0005] Third, the operation is not convenient. When taking out or placing the cylinders, it is necessary to manually remove or install the limiting structure one by one (such as removing the straps and adjusting the limiting blocks). Moreover, because the cylinders are stacked tightly, taking out or placing the bottom or deep cylinders requires moving the upper cylinders one by one, which is cumbersome and time-consuming, reducing work efficiency.
[0006] Fourth, limited adaptability. Traditional stacking racks have fixed limiting dimensions and tilt angles, making it difficult to adapt to liquefied gas cylinders of different specifications (such as height and diameter) or weights. Special stacking racks are required for cylinders of special sizes, increasing usage costs and management complexity.
[0007] In summary, existing LPG cylinder stacking racks have significant shortcomings in terms of safety and stability, space utilization, ease of operation, and adaptability. There is an urgent need for a new type of stacking rack design that can dynamically limit positions, adjust in conjunction with each other, and has strong adaptability. Utility Model Content
[0008] To achieve the above objectives, this utility model provides the following technical solution: a liquefied gas cylinder stacking rack, including a base, a frame fixedly installed on the base, and multiple placement mechanisms rotatably arranged on the frame, with two adjacent placement mechanisms connected by a connecting rod; one end of a jack is also fixedly installed on the base, and the other end of the jack abuts against the placement mechanism close to the base.
[0009] The placement mechanism includes a support plate, which is rotatably mounted on the frame via a swivel. A crossbeam is fixedly mounted on the central axis of the support plate. Two sets of support members are symmetrically fixedly mounted on the support plate with the crossbeam as the axis. A limit plate is also rotatably mounted on the support plate.
[0010] The placement mechanism further includes an adjustment drive component and a linkage component. Both the adjustment drive component and the linkage component are disposed on the support plate. One end of the linkage component is connected to the adjustment drive component, and the other end is connected to the limiting plate.
[0011] As a further improvement of this utility model, the adjustment drive assembly includes a limiting slide rail, which is fixedly mounted on the support plate. An adjustment support seat is slidably mounted on the limiting slide rail. One end of the adjustment support seat is provided with a compression spring, and the other end of the compression spring is fixedly mounted on the support plate.
[0012] The adjustment drive assembly also includes a connecting groove that extends through the support plate.
[0013] As a further improvement of this utility model, the linkage component includes a slide rail, which is fixedly disposed on the back of the support plate. A connecting rod is slidably disposed in the slide rail. One end of the connecting rod is connected to the adjusting support seat through the connecting groove, and the other end is connected to one end of the adjusting spring. The other end of the adjusting spring is provided with a T-shaped rod, which is slidably disposed in the slide rail.
[0014] As a further improvement of this utility model, the linkage component also includes two sliding grooves, which are formed on the bearing plate with the slide rail as the axis of symmetry. A rack is slidably arranged in the sliding grooves, and the rack is connected to the T-shaped rod.
[0015] As a further improvement of this utility model, a base is provided on the bearing plate, the limiting plate is rotatably mounted on the base, and a gear is provided on the connecting shaft between the limiting plate and the base, the gear meshing with the rack.
[0016] As a further improvement of this utility model, a plurality of connecting turntables are provided on the frame corresponding to the bearing plate, and the bearing plate is rotatably mounted on the connecting turntables.
[0017] As a further improvement of this utility model, a stop bar is provided on the adjusting support.
[0018] As a further improvement of this utility model, a slot is provided through the crossbeam, and the connecting rod connects the upper and lower adjacent bearing plates through the slot.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. Significantly Enhanced Safety and Stability: By adjusting the synergistic effect of the drive and linkage components, when the support plate tilts due to the jack, the center of gravity of the LPG cylinder shifts, pushing the adjusting support seat to slide along the limit rail. The compression spring deforms under pressure and, in conjunction with the T-shaped rod, rack, and gear structure, ultimately drives the limit plate to automatically rotate and cover the edge of the support plate, effectively blocking the cylinder and preventing the risk of it slipping due to vibration or tilting. Simultaneously, the elastic buffer design of the compression and adjusting springs absorbs vibration energy during transportation or handling, further enhancing the stability of the stored cylinder.
[0021] 2. Convenient and efficient operation: The bottom placement mechanism is driven by a jack to rotate, and the upper and lower support plates are tilted or reset synchronously through linkage, realizing a quick switch between the cylinder stacking and retrieval states. When retrieving a cylinder, simply lower the jack to reset the support plate to a horizontal position, and the adjustment drive component automatically pushes the cylinder back to its original position under the action of the compression spring. At the same time, the linkage component drives the limit plate to reset and release the obstruction, eliminating the need for manual adjustment of the limit structure one by one, greatly improving operational efficiency.
[0022] 3. Optimized space utilization: The frame is equipped with a multi-layer placement mechanism that rotates and tilts synchronously through linkage. While ensuring the stability of the cylinders, multiple cylinders can be compactly stacked. Compared with traditional fixed stacking racks, it significantly saves vertical space and is suitable for space-constrained scenarios such as warehousing and transportation.
[0023] 4. Enhanced structural reliability: The load-bearing plate is rotatably connected to the frame via a connecting turntable (with built-in bearings), and the connecting rod is connected to the upper and lower load-bearing plates via the connecting groove on the crossbeam (with built-in rotating bearings), ensuring that each component rotates flexibly and is subjected to uniform force; the baffle design on the adjustable load-bearing seat provides additional support for the gas cylinder, preventing it from tipping over during sliding. The overall structure is stable and durable, reducing maintenance costs.
[0024] 5. Wide adaptability: The tilt angle of the bearing plate can be flexibly controlled by adjusting the stroke of the jack, which can be adapted to liquefied gas cylinders of different sizes or weights; the automatic adjustment function of the limit plate does not require manual intervention and can adapt to various environments such as warehousing and transportation, meeting the diverse needs of safe storage and convenient management of cylinders.

[0034] See Figures 1 to 8 As shown, a liquefied gas cylinder stacking rack is characterized by: including a base (1), a frame 2 fixedly installed on the base 1, and multiple placement mechanisms 3 rotatably arranged on the frame 2, with two adjacent placement mechanisms 3 connected by a connecting rod 4; one end of a jack 5 is also fixedly installed on the base 1, and the other end of the jack 5 abuts against the placement mechanism 3 near the base 1.
[0035] The placement mechanism 3 includes a support plate 31, which is rotatably mounted on the frame 2 via a swivel 38. A crossbeam 32 is fixedly mounted on the central axis of the support plate 31. Two sets of support members 35 are symmetrically fixedly mounted on the support plate 31 with the crossbeam 32 as the axis. A limit plate 34 is also rotatably mounted on the support plate 31.
[0036] The placement mechanism 3 also includes an adjustment drive component 36 and a linkage component 37. The adjustment drive component 36 and the linkage component 37 are both disposed on the support plate 31. One end of the linkage component 37 is connected to the adjustment drive component 36, and the other end is connected to the limiting plate 34.
[0037] One by one, the liquefied gas cylinders to be stored are placed on the support plate 31. After all the liquefied gas cylinders are placed, the jack 5 is raised, causing the bottom placement mechanism 3 to rotate around the frame 2 via the swivel 38. During the rotation of the bottom placement mechanism 3, the adjacent support plate 31 is driven to rotate synchronously through the connecting rod 4.
[0038] During the rotation of the support plate 31, the center of gravity of the liquefied gas cylinder shifts due to tilting, causing it to slide closer to the adjustment drive component 36. The adjustment drive component 36 changes shape under the gravity of the liquefied gas cylinder, and the drive linkage component 37 drives the limit plate 34 to move. When the liquefied gas cylinder slides to the preset position, the limit plate 34 completely covers the edge of the support plate 31, effectively preventing the cylinder from slipping and ensuring safe and stable stacking.
[0039] After the liquefied gas cylinders are placed, the cylinders are firmly fixed due to the tilt angle of the bearing plate 31 and the precise cooperation of the limiting plate 34. Even if there is external vibration, the cylinders cannot be moved, which greatly improves the overall stability and safety of the stacking rack.
[0040] When it is necessary to remove the liquefied petroleum gas (LPG) cylinder, lower the height of jack 5 to reset the bottom placement mechanism 3 and keep it horizontal. Simultaneously, the LPG cylinder is pushed to its initial position by the adjusting drive assembly 36 for easy removal. At the same time, the adjusting drive assembly 36 drives the linkage assembly 37 to reset the limit plate 34, ensuring smooth cylinder removal. The operation is simple and efficient. The entire stacking rack is rationally designed, structurally stable, and suitable for various environments, ensuring the safe storage and convenient management of LPG cylinders.
[0041] In a preferred embodiment, the adjustment drive assembly 36 includes a limiting slide rail 361, which is fixedly mounted on the support plate 31. An adjustment support seat 362 is slidably mounted on the limiting slide rail 361. One end of a compression spring 363 is mounted on the adjustment support seat 362, and the other end of the compression spring 363 is fixedly mounted on the support plate 31.
[0042] When the support plate 31 tilts and the liquefied gas cylinder gradually slides down under gravity, it pushes the adjusting support seat 362 to move along the limiting slide rail 361, applying pressure to the compression spring 363 and changing its shape. During the movement of the adjusting support seat 362, the linkage component 37 responds synchronously, driving the limiting plate 34 to rotate around the support plate 31. After the support plate 31 reaches the preset tilt angle, the limiting plate 34 precisely covers the edge, ensuring the cylinder is stable.
[0043] Meanwhile, during transportation and handling, the compression spring 363 effectively buffers vibrations, prevents cylinders from moving accidentally, further enhances the stability and safety of the stacking rack, and ensures a smooth and reliable transportation process.
[0044] When the liquefied petroleum gas (LPG) cylinder needs to be removed, the support plate 31 rotates and returns to a horizontal position. As the tilt angle gradually decreases, the pressure on the adjusting support seat 362 gradually decreases, causing the adjusting support seat 362 to move and return to its original position under the action of the compression spring 363. Simultaneously, the linkage component 37 drives the limit plate 34 to return to its original position, ensuring that the cylinder can be smoothly removed. Throughout the process, the movement of the adjusting support seat 362 also gradually pushes the LPG cylinder back to its initial position for easy access by the operator.
[0045] The adjustment drive assembly 36 also includes a connecting groove 364, which is formed through the support plate 31. The connecting groove 364 tightly connects the adjustment support 362 and the linkage assembly 37 to ensure synchronized operation.
[0046] In a preferred embodiment, the linkage component 37 includes a slide rail 371, which is fixedly disposed on the back of the support plate 31. A connecting rod 372 is slidably disposed within the slide rail 371. One end of the connecting rod 372 is connected to the adjusting support seat 362 through the connecting groove 364, and the other end is connected to one end of the adjusting spring 374. The other end of the adjusting spring 374 is provided with a T-shaped rod 373, which is slidably disposed within the slide rail 371.
[0047] It should be noted that when the support seat 362 is moved, the connecting rod 372 drives the adjusting spring 374 to extend and retract, and the T-shaped rod 373 moves accordingly under the elastic action of the adjusting spring 374, ensuring that the linkage component 37 responds accurately and maintains the stability of the overall structure.
[0048] In a preferred embodiment, the linkage component 37 further includes two slide grooves 375, which are formed on the bearing plate 31 with the slide rail 371 as the axis of symmetry. A rack 378 is slidably arranged in the slide grooves 375, and the rack 378 is connected to the T-shaped rod 373.
[0049] In a preferred embodiment, a base is provided on the bearing plate 31, the limiting plate 34 is rotatably disposed on the base, and a gear 376 is provided on the connecting shaft between the limiting plate 34 and the base, the gear 376 meshing with the rack 378.
[0050] It needs to be explained that when the T-shaped rod 373 moves, it drives the rack 378 to slide synchronously. The sliding gear 376 of the rack 378 meshes and rotates, thereby causing the limiting plate 34 to rotate. During the placement of the liquefied gas cylinder, initially, because the liquefied gas cylinder is not fully placed, the rotation of the limiting plate 34 will contact the liquefied gas cylinder, forming an abutment. At this time, the limiting plate 34 stops rotating, meaning the T-shaped rod cannot continue to slide. As the liquefied gas cylinder continues to be placed, the adjusting support 362 is pressed and moves, causing the connecting rod 372 to continue sliding to pull the adjusting spring 374. This causes the adjusting spring 374 to continuously stretch and increase its elastic potential energy until the liquefied gas cylinder is fully placed. The limiting plate 34 then releases its contact with the liquefied gas cylinder. At this point, under the elastic action of the adjusting spring 374, the T-shaped rod 373 quickly returns to its original position, driving the rack 378 to slide. The gear 376 continues to rotate, and the limiting plate 34 also rotates to a position perpendicular to the support plate 31, blocking the liquefied gas cylinder and ensuring its stable placement.
[0051] In a preferred embodiment, a plurality of connecting turntables 6 are provided on the frame 2 corresponding to the bearing plate 31. The bearing plate 31 is rotatably mounted on the connecting turntables 6. The connecting turntables 6 are provided with bearing structures to ensure that the bearing plate 31 rotates flexibly and stably.
[0052] In a preferred embodiment, a baffle is provided on the adjusting support 362. The baffle contacts the liquefied gas cylinder and applies additional support force to the liquefied gas cylinder to prevent it from sliding or tipping over.
[0053] In a preferred embodiment, a slot 33 is provided through the crossbeam 32, and the connecting rod 4 connects the upper and lower adjacent bearing plates 31 through the slot 33. A rotating bearing is provided in the slot 33 to ensure that the connecting rod 4 can rotate freely in the slot 33, thereby enhancing the flexibility and stability of the overall structure, further optimizing the synergistic effect between the bearing plates 31, and improving the safety and reliability of the device.
[0054] In practical application, the liquefied petroleum gas (LPG) cylinder is placed stably on the support plate 31. The support plate 31 is rotated to a suitable angle using the jack 5, and the support seat 362 moves accordingly, ensuring tight contact between the LPG cylinder and the limiting plate 34 to prevent accidental slippage. At this time, the T-shaped rod 373, rack 378, and gear 376 work together to precisely control the rotation of the limiting plate 34, ensuring the cylinder's stability. The entire device is ingeniously designed, easy to operate, and greatly improves the safety of LPG cylinder storage.
[0055] When removing the liquefied gas cylinder, operate the jack 5 to rotate the bearing plate 31 in the opposite direction, adjust the bearing seat 362 to reset, and the limit plate 34 rotates accordingly to release the restriction on the liquefied gas cylinder. At the same time, the elastic potential energy is released through the compression spring 374, and the liquefied gas cylinder is slowly pushed to facilitate its removal.
[0056] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
