Description

Technical Field

[0001] This application relates to the field of nitrogen cylinder containment equipment technology, and in particular to a nitrogen cylinder clustering device. Background Technology

[0002] Currently, nitrogen cylinder bundles are commonly used as a gas supply source in industrial applications such as pipeline gas purging and nitrogen replacement. In existing technologies, nitrogen cylinder bundles typically employ a fixed frame structure (as seen in the existing patent CN114791086A, where the integrated nitrogen frame uses a welded fixed frame) and are assembled in units of 8, 12, or 16 cylinders to form integrated cylinder bundles. While this structure ensures continuous gas supply, it also presents some significant limitations: because the cylinder bundles are integrally welded, the overall equipment structure is highly rigid, occupying substantial storage space or site resources when idle. This is particularly problematic in companies with limited space or large-scale equipment, where long-term storage costs during idle periods increase significantly.

[0003] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0004] The technical problem to be solved by this application is to provide a nitrogen cylinder grouping device in view of the above-mentioned defects of the prior art, which aims to solve the problem that the existing technology uses a fixed frame structure that is integrally welded and formed to bundle nitrogen cylinder groups, which occupies a large space.

[0005] The technical solution adopted in this application to solve the technical problem is as follows:

[0006] A nitrogen cylinder clustering device, comprising:

[0007] Top-level barrier;

[0008] The upper support unit is detachably assembled with the top layer of the top layer shielding bar;

[0009] The lower support unit is located below the upper support unit and together with the upper support unit forms a nitrogen cylinder housing space; the bottom end of the upper support unit is inserted into the lower support unit and can move up and down relative to the lower support unit to expand or shrink the nitrogen cylinder housing space.

[0010] The reinforcing railing is detachably mounted on the upper support unit and / or the lower support unit; the reinforcing railing is arranged around the periphery of the nitrogen cylinder housing space.

[0011] The nitrogen cylinder clustering device, wherein the upper support unit includes:

[0012] Multiple support rods are arranged vertically and at intervals; there is a loading and unloading port between two adjacent support rods, which is connected to the nitrogen cylinder receiving space and is used to put in and take out the nitrogen cylinder;

[0013] The bottom of the top-level shielding bar is provided with multiple plug-in positions, and the support rod corresponds to each of the plug-in positions and is detachably plugged in.

[0014] The nitrogen cylinder clustering device, wherein the reinforcing rails include:

[0015] The reinforcing rail body is used for detachable assembly with the support rod; the reinforcing rail body is provided with a notch, which corresponds to the loading and unloading port;

[0016] A stop bar is located at the notch, and both ends are detachably assembled to the support rod to block and open the loading and unloading port.

[0017] The nitrogen cylinder clustering device, wherein the reinforcing rail body includes:

[0018] Multiple sleeves, each corresponding to a support rod, are detachably sleeved onto the support rod;

[0019] A crossbar is installed between two adjacent sleeves.

[0020] The nitrogen cylinder clustering device includes U-shaped sleeves on both sides of the notch, with the openings of the U-shaped sleeves facing the loading and unloading port, and both ends of the U-shaped sleeves located outside the loading and unloading port.

[0021] The nitrogen cylinder clustering device further includes:

[0022] A connecting piece is disposed at the end of the stop bar, and both the upper and lower ends of the connecting piece extend beyond the stop bar; the connecting piece is fitted with the support rod at the loading and unloading port and is detachably connected.

[0023] The nitrogen cylinder clustering device, wherein the support rod is a square support rod.

[0024] The nitrogen cylinder clustering device further includes:

[0025] A gas collection unit is installed on the top-level shielding railing and is connected to each nitrogen cylinder.

[0026] At least two connectors are provided at the bottom of the top-level shielding bar;

[0027] A hanging component is detachably connected to the connecting component; the hanging component has a receiving cavity, and the gas collection unit is at least partially located within the receiving cavity.

[0028] The nitrogen cylinder clustering device, wherein the gas collecting unit includes:

[0029] The gas collection tube passes through each receiving cavity in sequence;

[0030] Multiple vent pipes are installed on the gas collecting pipe and connected to the gas collecting pipe; each vent pipe is connected to a nitrogen cylinder in a corresponding manner; the hanging component is located between two adjacent vent pipes.

[0031] Beneficial effects: When the nitrogen cylinder cluster assembly is idle, the vertical height of the nitrogen cylinder storage space can be significantly reduced by moving the upper support unit downwards to be close to or near the lower support unit.

It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0039] This application provides a nitrogen cylinder grouping device, such as... Figure 1 , Figure 2 and Figure 4 As shown, the nitrogen cylinder clustering device includes: a top-level shielding barrier 1, an upper-level support unit 2, a lower-level support unit 3, and a reinforcing barrier 4; the top of the upper-level support unit 2 is detachably assembled with the top-level shielding barrier 1; the lower-level support unit 3 is located below the upper-level support unit 2, and together with the upper-level support unit 2, they enclose a nitrogen cylinder receiving space; the bottom end of the upper-level support unit 2 is inserted into the lower-level support unit 3, and can move up and down relative to the lower-level support unit 3 to scale the nitrogen cylinder receiving space; the reinforcing barrier 4 is detachably assembled on the upper-level support unit 2 and / or the lower-level support unit 3; the reinforcing barrier 4 is arranged around the periphery of the nitrogen cylinder receiving space.

[0040] Specifically, the top-level shielding barrier 1 supports and reinforces the upper-level support unit 2 from the top of the upper-level support unit 2; the top of the upper-level support unit 2 is detachably assembled with the top-level shielding barrier 1, and the bottom of the upper-level support unit 2 is movably plugged into the lower-level support unit 3, and the upper-level support unit 2 and the lower-level support unit 3 together form a nitrogen cylinder containing space; then, when the upper-level support unit 2 moves upward, reducing the overlap area between the upper-level support unit 2 and the lower-level support unit 3, the distance between the top-level shielding barrier 1 and the lower-level support unit 3 increases, and the nitrogen cylinder containing space expands; when the upper-level support unit 2 moves up and down, increasing the overlap area between the upper-level support unit 2 and the lower-level support unit 3, the distance between the top-level shielding barrier 1 and the lower-level support unit 3 decreases, and the nitrogen cylinder containing space decreases.

[0041] The reinforcing railing 4 is arranged around the perimeter of the nitrogen cylinder containing space and is used to support and reinforce the upper support unit 2 and / or the lower support unit 3 to ensure that the upper support unit 2 and / or the lower support unit 3 can maintain their current state, thereby maintaining the width of the nitrogen cylinder containing space.

[0042] When the nitrogen cylinder cluster assembly is idle, the upper support unit 2 can be moved downwards to be close to or near the lower support unit 3, thereby significantly reducing the vertical height of the nitrogen cylinder storage space. In this state, the overall volume of the assembly is significantly reduced. This structural design allows for compact storage without disassembly, preserving the integrity of the cluster assembly structure while greatly reducing the floor space and height requirements when the assembly is idle or in transport. This not only helps improve warehouse space utilization and reduce the storage area required for stacking equipment, but also facilitates loading and handling, improving equipment turnover efficiency and operational flexibility.

[0043] One embodiment of this application, such as Figure 2 As shown, the upper support unit 2 includes multiple support rods 21, which are arranged vertically and at intervals. There is a loading and unloading port 5 between two adjacent support rods 21. The loading and unloading port 5 is connected to the nitrogen cylinder receiving space and is used to pick up and put in the nitrogen cylinder 100. The bottom of the top shield 1 is provided with multiple plug-in positions. The support rods 21 correspond to the plug-in positions one by one and are detachably plugged in.

[0044] Specifically, the multiple support rods 21 are arranged parallel to each other and spaced apart, and the multiple support rods 21 are arranged sequentially around the periphery of the nitrogen cylinder receiving space. Each support rod 21 is arranged vertically, and there is a loading and unloading port 5 between two adjacent support rods 21; that is, there is a large gap between two adjacent support rods 21, which is sufficient for the nitrogen cylinder 100 to pass through the gap to be stored in the nitrogen cylinder receiving space, and to be taken out from the nitrogen cylinder receiving space. This gap forms the loading and unloading port 5.

[0045] The bottom of the top-level shielding barrier 1 is provided with a plug-in position, which corresponds one-to-one with the support rod 21 and is used for detachable plug-in engagement with the support rod 21. Thus, when all the support rods 21 are inserted into their corresponding plug-in positions, the detachable assembly between the top-level shielding barrier 1 and the upper support unit 2 can be completed.

[0046] Since the upper support unit 2 includes multiple support rods 21, in order to prevent the multiple support rods 21 from becoming skewed after being installed at the bottom of the top shield 1, a reinforcing railing 4 can be installed on the upper support unit 2 in this application, so as to ensure the vertical state of all support rods 21 and maintain the nitrogen cylinder containment space.

[0047] The lower support unit 3 also includes multiple support rods, which are arranged vertically and surround the nitrogen cylinder containment space. The difference between the lower support unit 3 and the upper support unit 2 is that the support rods of the lower support unit 3 are hollow, allowing the support rods 21 of the upper support unit 2 to be inserted into the support rods of the lower support unit 3 and to move up and down relative to the support rods of the lower support unit 3 under external force. To prevent the lower support unit 3 from tilting after being installed below the upper support unit 2, a reinforcing rail 4 can be installed on the lower support unit 3 to ensure the verticality of all support rods 21 in the lower support unit 3, thus maintaining the nitrogen cylinder containment space.

[0048] It should be noted that the structural design of the nitrogen cylinder cluster device in this application has a high degree of detachability and flexibility. Specifically, the connection between the reinforcing rail 4 and the upper support unit 2, as well as the connection between the reinforcing rail 4 and the lower support unit 3, adopt a detachable assembly structure, and the connection between the top shielding rail 1 and the upper support unit 2 is also detachable.

[0049] With this modular, detachable structure, when the nitrogen cylinder cluster device is idle or needs storage or transportation, the nitrogen cylinder storage space can be compressed by lowering the upper support unit 2, and the top-level shielding railing 1 and reinforcing railing 4 can be further removed. After disassembly, the multiple support rods 21 of the upper support unit 2 can be stacked sequentially, and the multiple support rods 21 of the lower support unit 3 can also be compactly stacked, thereby significantly reducing the overall volume of the nitrogen cylinder cluster device. This stacking method facilitates unified storage and improves the space utilization efficiency of the components. Compared with the traditional integral welded structure, this detachable and stackable design exhibits stronger adaptability and convenience in warehousing and transportation, significantly reducing the floor space occupied in non-working states and lowering logistics and warehousing costs. It is evident that the nitrogen cylinder cluster device in this application not only meets the requirements for safe and stable storage of nitrogen cylinders 100, but also takes into account the compact storage requirements of the equipment during non-operational phases, demonstrating significant practicality and economic value.

[0050] like Figure 1 and Figure 4 As shown, the upper support unit 2 and the lower support unit 3 are connected by threaded connectors 6 such as screws and bolts. Specifically, the threaded connectors 6 are placed at the overlap between the upper support unit 2 and the lower support unit 3, and are detachably threaded to both the upper support unit 2 and the lower support unit 3, thereby preventing the upper support unit 2 from moving relative to the lower support unit 3 under gravity or pressure, and limiting the height of the nitrogen cylinder containing space. The support rod of the lower support unit 3 has multiple threaded holes along the vertical direction. Through the cooperation of the threaded holes and the threaded connectors 6, the height of the nitrogen cylinder containing space can be adjusted and positioned.

[0051] Understandably, the reinforcing rail 4 can also be detachably connected to the support rod 21 via threaded connectors, thereby positioning the reinforcing rail 4 and preventing it from moving under external force; and when it is necessary to adjust or move the upper support unit 2, the threaded connectors can be removed.

[0052] One embodiment of this application, such as Figure 1 and Figure 3 As shown, the reinforcing railing 4 includes a reinforcing railing body 41 and a stop bar 42; the reinforcing railing body 41 is detachably assembled with the support rod 21; a notch 411 is provided on the reinforcing railing body 41, the notch 411 corresponds to the loading and unloading port 5; the stop bar 42 is located at the notch 411, and both ends are detachably assembled with the support rod 21 to block and open the loading and unloading port 5.

[0053] Specifically, the reinforcing railing 4 is not a fixed structure formed by welding, but a split structure including the reinforcing railing body 41 and the baffle 42; wherein the reinforcing railing body 41 has a notch 411, so that after being assembled with the upper support unit 2 or the lower support unit 3, the notch 411 can correspond to the loading and unloading port 5. For nitrogen cylinders 100 with a large longitudinal length, they can be put into the nitrogen cylinder receiving space or taken out from the nitrogen cylinder receiving space directly from the loading and unloading port 5, without having to load and unload along the longitudinal direction, which reduces the difficulty of loading and unloading and improves the efficiency of loading and unloading.

[0054] The stop lever 42 is used for detachable assembly with the support rod 21 at the notch 411. After assembly, the stop lever 42 can block the loading / unloading port 5 and the notch 411, thereby limiting the nitrogen cylinder 100 within the nitrogen cylinder receiving space. When it is necessary to remove or place the nitrogen cylinder 100, the stop lever 42 is removed to expose and open the loading / unloading port 5, allowing the nitrogen cylinder 100 to be removed or placed.

[0055] In one embodiment of this application, the top-level shielding bar 1 is square, the upper-level support unit 2 has four support rods 21, and the lower-level support unit 3 also has four support rods 21, making the overall appearance of the nitrogen cylinder cluster device square. The nitrogen cylinder cluster device can be configured to accommodate either one nitrogen cylinder 100 or four nitrogen cylinders 100, depending on the dimensions of the top-level shielding bar 1 and the reinforcing bar 4. When the nitrogen cylinder cluster device can accommodate four nitrogen cylinders 100, and four nitrogen cylinders 100 are placed in the cluster, all four nitrogen cylinders 100 can contact the reinforcing bar 4, and each pair of the four nitrogen cylinders 100 contacts the others, thereby reducing or even preventing the shaking of the four nitrogen cylinders 100 within the nitrogen cylinder accommodating space.

[0056] Understandably, when the nitrogen cylinder clustering device is a clustering device that can accommodate 4 nitrogen cylinders 100, under special circumstances, only 2 nitrogen cylinders 100 can be placed in the nitrogen cylinder receiving space, and a baffle 42 can be set in the nitrogen cylinder receiving space. The two ends of the baffle 42 are respectively detachably connected to the reinforcing rail 4, and the baffle 42 is in contact with the 2 nitrogen cylinders 100, which can reduce or even avoid the shaking of the 2 nitrogen cylinders 100 in the nitrogen cylinder receiving space.

[0057] like Figure 3 As shown, the reinforced fence body 41 includes multiple sleeves 401 and crossbars 402; the multiple sleeves 401 correspond one-to-one with the support rods 21 and are detachably sleeved on the support rods 21; the crossbars 402 are arranged between two adjacent sleeves 401.

[0058] Specifically, taking the example that both the upper support unit 2 and the lower support unit 3 include 4 support rods 21, the reinforced fence body 41 includes 4 sleeves 401 and 3 crossbars 402; each crossbar 402 has a sleeve 401 at both ends, and the sleeve 401 is used to be detachably sleeved on the support rod 21.

[0059] It should be noted that the sleeve 401 can move along the support rod 21 under the action of external force, thereby changing the position of the reinforced fence body 41 on the upper support unit 2 to adapt to the up and down movement adjustment of the upper support unit 2.

[0060] The sleeves 401 on both sides of the notch 411 are U-shaped sleeves, with the openings of the U-shaped sleeves facing the loading and unloading port 5, and both ends of the U-shaped sleeves located outside the loading and unloading port 5, so that the U-shaped sleeves will not extend into the loading and unloading port 5 and interfere with the loading and unloading of the nitrogen cylinder 100. After the U-shaped sleeves are fitted onto the corresponding support rods 21, the stop rods 42 are detachably assembled with the support rods 21 from the opening side of the U-shaped sleeves, thereby forming a closed square structure for the reinforcing rail 4.

[0061] like Figure 3As shown, the nitrogen cylinder grouping device also includes a connecting piece 7, which is located at the end of the baffle 42, and both the upper and lower ends of the connecting piece 7 extend beyond the baffle 42; the connecting piece 7 is in contact with the support rod 21 at the loading and unloading port 5 and can be detachably connected.

[0062] Specifically, for each stop lever 42, there are two connecting pieces 7, meaning that connecting pieces 7 are provided at both ends of the stop lever 42. The upper and lower ends of the connecting pieces 7 extend beyond the stop lever 42, and the connecting pieces 7 are used for detachable assembly with the support rod 21. The provision of connecting pieces 7 at both ends of the stop lever 42 facilitates assembly of the stop lever 42 at the loading / unloading port 5 and increases the contact area between the stop lever 42 and the support rod 21, thereby improving the stability of the stop lever 42 during assembly at the loading / unloading port 5.

[0063] In one embodiment of this application, the support rod 21 is a square support rod, giving it four planes on its outer surface. When the support rod 21 of the upper support unit 2 contacts the support rod of the lower support unit 3, the square structure design of the support rod 21 increases the number of contact planes between the upper support unit 2 and the lower support unit 3, allowing only vertical movement between them without relative rotation.

[0064] like Figure 1 and Figure 4 As shown, the top-level barrier 1 includes a square barrier body 11 and reinforcing rods 12; the insertion points corresponding to the support rods 21 of the upper support unit 2 are located at the four corners of the square barrier body 11 and are square in shape to adapt to the shape of the support rods 21 of the upper support unit 2. The reinforcing rods 12 are located inside the square barrier body 11 and are connected to the square barrier body 11.

[0065] The nitrogen cylinder clustering device also includes a gas collection unit 8 (such as...) Figure 1 , Figure 2 and Figure 4 As shown), at least two connectors 9 (such as...) Figure 5 As shown), and hanging component 10 (as shown) Figure 2 and Figure 5 (as shown); the gas collection unit 8 is disposed on the top shield 1 and is connected to each nitrogen cylinder 100 respectively; the connector 9 is disposed at the bottom of the top shield 1; the hanging part 10 is detachably connected to the connector 9; the hanging part 10 has a receiving cavity, and the gas collection unit 8 is at least partially located in the receiving cavity.

[0066] Specifically, the gas collection unit 8 is connected to each nitrogen cylinder 100, thereby collecting nitrogen from each nitrogen cylinder 100 and supplying it to the outside. The connector 9 is located at the bottom of the reinforcing rod 12 and is used to connect to the load-bearing hanging member 10, thereby positioning the gas collection unit 8 below the top-level shielding railing 1 through the hanging member 10.

[0067] In one embodiment of this application, the connector 9 is a U-shaped connector with both ends arranged vertically. One end of the U-shaped connector is connected to the reinforcing rod 12, and the other end is suspended downwards, forming a suspended end. The hanger 10 is a U-shaped hanger with its opening facing upwards, and both ends of the U-shaped hanger are connected to the suspended end of the U-shaped connector, so that the top of the receiving cavity is blocked by the suspended end of the U-shaped connector, and the gas collection unit 8 can be inserted into the receiving cavity from the side, thereby realizing the suspension of the gas collection unit 8 below the top layer shielding bar 1. The number of U-shaped connectors is equal to the number of U-shaped hangers, and they are connected in a one-to-one correspondence.

[0068] like Figure 2 , Figure 4 and Figure 5 As shown, the gas collection unit 8 includes a gas collection pipe 81 and multiple vent pipes 82; the gas collection pipe 81 passes through each receiving cavity in sequence; the vent pipe 82 is disposed on the gas collection pipe 81 and communicates with the gas collection pipe 81; the vent pipe 82 is connected to the nitrogen cylinder 100 in a one-to-one correspondence; the hanging component 10 is located between two adjacent vent pipes 82.

[0069] Specifically, the vent pipe 82 is used to connect the nitrogen cylinder 100 to the gas collecting pipe 81, thereby supplying nitrogen to the outside through the gas collecting pipe 81. Vent pipes 82 are arranged on both sides of the horizontal direction of each U-shaped hanging component, so that the gas collecting pipe 81 can be stably suspended below the top-level shield 1 by the limiting of the vent pipe 82, and the gas collecting pipe 81 is prevented from falling off.

[0070] In summary, this application provides a nitrogen cylinder clustering device, comprising: a top-level shielding barrier; an upper support unit, the top of which is detachably assembled with the top-level shielding barrier; a lower support unit located below the upper support unit, forming a nitrogen cylinder receiving space between the upper support unit and the lower support unit; the bottom end of the upper support unit is inserted into the lower support unit and can move up and down relative to the lower support unit to scale the nitrogen cylinder receiving space; a reinforcing barrier; the reinforcing barrier is detachably assembled to the upper support unit and / or the lower support unit; the reinforcing barrier is arranged around the periphery of the nitrogen cylinder receiving space. When the nitrogen cylinder clustering device is idle, the vertical height of the nitrogen cylinder receiving space can be significantly reduced by moving the upper support unit downwards to be close to or near the lower support unit. In this state, the volume of the entire device is significantly reduced. Through this structural design, compact storage can be achieved without disassembly, which not only preserves the integrity of the cluster device structure, but also greatly reduces the floor space and height requirements of the cluster device in idle or transportation states. This not only helps to improve the space utilization of the warehouse and reduce the storage area required for stacking equipment, but also facilitates loading and handling, and improves the turnover efficiency and usage flexibility of the equipment.

[0071] It should be understood that the application of this application is not limited to the examples above.
