DETAILED DESCRIPTION

[0025] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0026] The present embodiment provides a transport device for gas cylinders and a transport rack thereof. The transport rack has a grid-like structure with a hollow top at the lower layer. The lower hollow space can accommodate the lower gas cylinders, and the upper grid-like structure can be used in conjunction with the positioning tooling to set up the upper gas cylinders, thereby realizing double-layer gas cylinder transportation on a single-layer transport rack. Multiple transport racks can also be quickly plugged and assembled into an extended or widened frame structure, i.e., a transport device, so that a large number of large-volume gas cylinders can be transported in double layers, and while ensuring the safety and reliability of the structure, the overall structure is simple, the process is simple, the disassembly is quick, and the reliability is high, thereby improving work efficiency and saving transportation costs.

[0027] Please refer to Figure 1 and Figure 2 The multiple transport racks 100 in the transport device 1000 are divided into two side-by-side vertical columns, wherein any two adjacent transport racks 100 are spliced ​​with each other by sharing the pipe fittings (vertical pipe 11 and horizontal pipe 13) on the same side, and the remaining horizontal pipes 13, supporting beams 2 and limiting beams 3 are respectively butt-jointed to finally form a complete frame structure.

[0028] Considering the stability of transportation, the above-mentioned transport rack 100 can use four gas cylinders as a module, that is, two gas cylinders are placed on the upper layer and the lower layer respectively for double-layer transportation. Of course, if the length of the replacement transport vehicle is longer, multiple transport racks 100 can be spliced ​​to adaptively extend the overall length of the transport device 1000 to transport more gas cylinders, thereby achieving higher versatility and economy.

[0029] A single transport rack 100 mainly includes a rack body 1 and a plurality of supporting beams 2 , limiting cross beams 3 and diagonal braces 4 arranged on the rack body 1 .

[0030] The frame 1 includes a plurality of vertical tubes 11 extending vertically and a horizontal tube 13 extending horizontally. A snap-fit ​​structure is provided at both ends of the vertical tubes 11 and the horizontal tubes 13 to snap-fit ​​and enclose a detachable rectangular hollow inner cavity frame structure. Therefore, the rectangular inner cavity of the lower layer of the frame 1 can be matched with an additionally configured snap-fit ​​tooling to accommodate the lower layer of gas cylinders, and the cross-shaped grid structure on the top surface of the frame 1 can be snap-fitted with an additionally configured snap-fit ​​tooling to fix the upper layer of gas cylinders, thereby realizing double-layer gas cylinder transportation on a single-layer transport rack.

[0031] In this embodiment, the horizontal tube 13, the vertical tube 11, the supporting beam 2 and the limiting cross beam 3 are all standard square tubes. Compared with the common round tube, the square tube has a straight peripheral wall that can better fit with other components and achieve a more stable transportation effect. The standardized square tube makes the installation, disassembly and transportation process very convenient, and has high versatility and economy.

[0032] Please refer to Figure 3 , slots 101 are provided on each side of the outer circumference of both ends of the vertical tube 11. There are multiple slots 101 on the same side of the vertical tube 11, and they are arranged at intervals along the vertical direction. The slots 101 of different heights can be connected to the horizontal tubes 13 with different height requirements to match the gas cylinders of different heights and leave appropriate storage space for them. In addition, there are at least two slots 101 at the same height to improve the connection strength.

[0033] In this embodiment, the clamping structure includes clamping members 130 respectively disposed at two ends of the transverse tube 13 .

[0034] The clamping member 130 extends in the horizontal direction to be inserted into the slot 101 to form a clamping connection. In this embodiment, the clamping member 130 is in the form of a sheet, and the slot 101 is in the form of a vertical bar. The clamping member 130 and the slot 101 can be quickly aligned and assembled, and have the advantages of convenient disassembly and assembly, and reliable fixation and anti-slip. In other embodiments, the clamping structure between the vertical tube 11 and the horizontal tube 13 can also be a clamp, a mortise and tenon, etc.

[0035] Furthermore, a pad 133 is provided at the end of the transverse tube 13 for fitting the vertical tube 11 to increase the contact area between the transverse tube 13 and the vertical tube 11. The pad 133 is larger than the transverse tube 13, and its periphery exceeds the periphery of the transverse tube 13. In addition, a larger connecting bottom plate 333 can be laid at the bottom of the vertical tube 11 to increase the contact area of ​​the gas cylinder and prevent it from slipping during transportation.

[0036] For the convenience of description, the transverse tube 13 includes a first transverse tube 131 extending in the longitudinal direction of the frame body 1 , and a second transverse tube 132 extending in the transverse direction of the frame body 1 .

[0037] The length of the first transverse tube 131 can be increased according to the specific demand for transporting multiple gas cylinders; while the length of the second transverse tube 132 is relatively short, and its length is specifically greater than the total width of two adjacent gas cylinders.

[0038] The second transverse tube 132 is disposed lower than the first transverse tube 131 by corresponding to the lower slot 101. That is, the planes of the first transverse tube 131 and the second transverse tube 132 are at different heights, so as to provide a stacking space for the subsequent installation of the supporting beam 2, so that the upper surface of the supporting beam 2 is flush with the upper surface of the first transverse tube 131.

[0039] A plurality of holders 135 are disposed on each second transverse tube 132 at intervals.

[0040] Each clamping seat 135 is used to be arranged corresponding to each supporting beam 2, and the clamping seat 135 has an upward notch to clamp the supporting beam 2 in the notch. Specifically, the clamping seat 135 includes two oppositely arranged protrusions 1351, each protrusion 1351 is protrudingly arranged on the upper surface of the cross tube 13, and a notch is formed between the two protrusions 1351. In other embodiments, the structure of the clamping seat 135 is not limited to the above, as long as the clamping seat 135 can clamp the supporting beam 2.

[0041] A plurality of supporting beams 2 are laid at intervals on the upper end of the frame 1 to jointly support the upper gas cylinders.

[0042] Specifically, all the support beams 2 are located between two first transverse tubes 131 disposed opposite to each other on the left and right sides. In addition, each support beam 2 extends in the longitudinal direction of the frame 1 , and a plurality of limiting holes 201 are provided at intervals on the support beam 2 , and the limiting holes 201 are connected to the limiting transverse beam 3 correspondingly.

[0043] The support beam 2 is supported by the second transverse tube 132, and the upper surface of the support beam 2 is kept flush with the upper surface of the first transverse tube 131, so that the upper gas cylinder can be placed flat. The ends of the support beam 2 are overlapped on the two second transverse tubes 132 arranged opposite to each other in the front and rear through the clamping seats 135. The main part of the support beam 2 is also clamped on the clamping seats 135 on several second transverse tubes 132 at the same time.

[0044] A plurality of limiting cross beams 3 are placed at intervals on the upper surface of the supporting beam 2 , and each limiting cross beam 3 is movable relative to the supporting beam 2 , and is detachably connected to the limiting holes 201 at different positions via fasteners.

[0045] The limiting cross beam 3 is not only used to limit the placement position of the upper gas cylinder, but also to reinforce the connection of the supporting beam 2 to prevent twisting and movement during transportation, thereby ensuring the safety of transportation of the upper gas supply system.

[0046] Each limiting cross beam 3 extends in the transverse direction of the frame body 1 , that is, the extending direction of the limiting cross beam 3 is consistent with the extending direction of the second transverse tube 132 .

[0047] Wherein, baffles 31 are respectively provided at both ends of the limiting beam 3. The baffles 31 are parallel to the cross section of the limiting beam 3 and extend downward beyond the lower surface of the limiting beam 3. The two baffles 31 are respectively in contact with the inner side surfaces of two opposite first transverse tubes 131, thereby limiting the displacement of the limiting beam 3 in the lateral direction.

[0048] A plurality of fixing members 33 are arranged at intervals on the main body of the limiting beam 3, each fixing member 33 is provided with a through hole 301 adapted to the limiting hole 201, and is fixed to each supporting beam 2 in a one-to-one correspondence through the limiting hole 201. At the same time, the fixing members 33 can adjust the longitudinal spacing between two adjacent limiting beams 3 by connecting different limiting holes 201, so as to meet the transportation requirements of gas cylinders of different sizes (mainly different lengths).

[0049] Please refer to Figure 4 The fixing member 33 includes side plates 331 respectively arranged on both sides of the limiting beam 3, and bottom plates 333 respectively connected to the side plates 331. Both side plates 331 extend downward and parallel from the limiting beam 3, and the bottom plates 333 respectively connect the side plates 331 to form a rectangular frame, the size of which is slightly larger than the size of the supporting beam 2, and the rectangular frame can be sleeved on the outer periphery of the supporting beam 2. The side plates 331 are oppositely provided with through holes 301, and the side plates 331 are respectively attached to two opposite sides of the supporting beam 2, so that the through holes 301 correspond to the limiting holes 201, and are bolted together by matching fasteners.

[0050] Of course, the fixing member 33 may only include two side plates 331. The two side plates 331 extend downward to correspondingly clamp the two sides of the supporting beam 2, and also form a bolt connection.

[0051] In other embodiments, the detachable connection structure of the support beam 2 and the limiting beam 3 formed by the fixing member 33 and the through hole 301 and the limiting hole 201 can also be replaced by other clips, such as a cross clip, a U-shaped bolt, etc.

[0052] Please refer back to Figure 2 The frame 1 is also provided with a plurality of diagonal braces 4 to ensure the overall strength and improve the stability of transportation.

[0053] Each group of diagonal braces 4 is located on different sides of the frame body 1 to connect the vertical pipe 11 and the horizontal pipe 13 .

[0054] Each group includes at least two diagonal braces 4. One end of the two diagonal braces 4 is adjacent and fixed to the middle of the same first transverse tube 131 by bolts, and the other ends of the two diagonal braces 4 are relatively separated and obliquely bolted to two adjacent columns. The ends of the two ends of the above-mentioned diagonal braces 4 are respectively provided with connecting plates 41, which extend vertically or horizontally to fit the tube walls of the transverse tube 13 and the vertical tube 11 respectively, and form a detachable connection through the matching bolt holes and bolt members.

[0055] The gas cylinder of the present application can be either an LNG cylinder for storing LNG or a cylinder for storing other fuel gases, such as hydrogen, propane, ethane and other fuel gases.

[0056] In summary, the gas cylinder transport rack 100 provided in this embodiment has the following advantages and positive effects:

[0057] The transport rack 100 includes a frame 1, a support beam 2 and a limit beam 3, wherein the frame 1 includes a plurality of vertical pipes 11 extending vertically and a horizontal pipe 13 extending horizontally, and the inner cavity thereof is used to accommodate the lower gas cylinder. A plurality of support beams 2 are laid at intervals on the upper end of the frame 1, and the limit beam 3 is connected to each support beam 2 in a cross shape, so as to be clamped with an additionally configured clamping tooling, and is used to fix the upper gas cylinder, thereby realizing the double-layer gas cylinder transportation of the single-layer transport rack. Among them, each component adopts a standard square tube, and its connection form adopts a clamping structure to realize rapid disassembly and connection. Due to the high degree of standardization and modularization of the pipe fittings, it can be assembled on demand according to the actual situation. The structure after molding is relatively stable, avoiding twisting and movement between the pipe fittings, and can effectively improve the working state during transportation. In addition, the space occupied after disassembly is small, which is convenient for the transportation and storage management of the unloaded gas cylinders or on-site storage, and greatly saves transportation costs and management costs.

[0058] This embodiment also provides a gas cylinder transport device 1000, which is an extended frame structure assembled from a plurality of transport frames 100, so that it can be adaptively expanded according to the length of the vehicle to increase the overall length; the overall adaptability is high and the strength is high. Each component adopts a detachable snap-on and other quick connection methods to achieve high standardization and high adaptability of parts, reduce the types of parts, reduce costs and improve efficiency, improve product reliability, and facilitate subsequent transportation and storage after being disassembled into parts.
