Description

Technical Field

[0001] This utility model relates to the field of portable liquid oxygen tank device. Background Technology

[0002] Liquid oxygen tanks, typically cylindrical or spherical in shape, are used to store liquid oxygen and supply it to oxygen-demanding systems. They have a wide range of applications in industry, medicine, and aquaculture. In industry, liquid oxygen is used for cutting and welding metals and in steelmaking; in medicine, it provides oxygen to hospitals for patient treatment; and in aquaculture, it provides oxygen for high-density aquaculture.

[0003] Currently, the most common way to move liquid oxygen tanks is by forklift. When moving a liquid oxygen tank with a forklift, the forks must be inserted into the bottom of the tank to lift it and move it. However, this method has several problems. First, forklift operation requires precise control by professional personnel. If the forks are not inserted accurately or the operation is improper, the tank can easily collide with it, causing damage and liquid oxygen leakage, creating safety hazards. Second, the stability during transport is poor. The forklift's movement is affected by factors such as ground flatness, speed, and its own balance. If it encounters uneven ground, sudden braking, or turning, the liquid oxygen tank is prone to swaying and tilting, increasing the risk of collision and leakage. Forklift transport of liquid oxygen tanks presents many safety and practical problems, urgently requiring a better solution. Utility Model Content

[0004] Therefore, there is a need to provide a portable liquid oxygen tank device to solve the problems described in the background art.

[0005] To achieve the above objectives, this utility model provides a movable liquid oxygen tank device, including a supporting base, multiple structural rods vertically arranged on the supporting base, a structural frame fixedly connected to the top ends of the multiple structural rods, and a flip door hinged to one of the structural rods. Multiple support rods extend downward from the bottom surface of the supporting base, and the support rods are distributed at least at the four corners of the supporting base. The supporting base is provided with non-collinear protrusions of no less than three on its surface. When the liquid oxygen tank is placed in the center of the supporting base, the liquid oxygen tank is constrained by the multiple protrusions.

[0006] Furthermore, the supporting chassis is a plate structure or is formed by arranging and combining multiple pipe components.

[0007] Furthermore, there are four protrusions, which are distributed vertically and horizontally.

[0008] Furthermore, the supporting chassis is square.

[0009] Furthermore, the flip-up door is hinged to a structural rod in the horizontal direction.

[0010] Furthermore, the upper surface of the supporting chassis is provided with an anti-slip layer.

[0011] Furthermore, the protrusion is slidably locked to the supporting chassis.

[0012] Furthermore, the supporting chassis is provided with the same number of strip-shaped through slots as the protrusions. The strip-shaped through slots are arranged below the protrusions along the diameter of the circle formed by the protrusions. The bottom surface of the protrusion is provided with a downwardly extending threaded post. The threaded post can pass through the strip-shaped through slot. The limiting of the strip-shaped through slot allows the protrusion to slide in the length direction of the strip-shaped through slot. It is also threadedly connected to the threaded post by a nut, so that the protrusion is locked at a certain point in the strip-shaped through slot.

[0013] Furthermore, the strip groove is provided with scale lines.

[0014] Furthermore, the supporting chassis, structural rods, structural frame, flip door, and protrusions are all made of stainless steel.

[0015] Unlike existing technologies, the above technical solution solves the problems of easy shaking, tipping and leakage when forklifts transport liquid oxygen tanks, improves the stability and safety of liquid oxygen tanks during movement, reduces operational complexity and site requirements, and also reduces costs and safety hazards.

[0032] Please see Figures 1 to 5 This embodiment provides a movable liquid oxygen tank device 1, including a supporting base 10, a plurality of structural rods 20 vertically arranged on the supporting base 10, a structural frame 30 fixedly connected to the top of the plurality of structural rods 20, and a flip door 40 hinged to one of the structural rods 20. A plurality of support rods 50 extend downward from the bottom surface of the supporting base 10, and the support rods 50 are distributed at least at the four corners of the supporting base 10. The supporting base 10 is provided with non-collinear protrusions 60, and the number of protrusions is not less than three. When the liquid oxygen tank is placed in the center of the supporting base 10, the liquid oxygen tank is limited by the plurality of protrusions 60.

[0033] The supporting chassis 10 is the basic component of the liquid oxygen tank device. It is a square plate with multiple support rods 50 extending downwards from its bottom surface. These support rods 50 are located at the four corners of the supporting chassis 10 to stably support the entire device. Multiple structural rods 20 are vertically arranged on the top of the supporting chassis 10. These structural rods 20 are evenly distributed and extend upwards, with their tops fixedly connected to a structural frame 30. The structural frame 30 is a square frame that is firmly connected to the tops of the multiple structural rods 20, forming a stable frame structure. A flip-up door 40 is hinged to one of the structural rods 20. The flip-up door 40 can be opened outwards to facilitate the insertion or removal of the liquid oxygen tank from the side. The supporting chassis 10, structural rods 20, structural frame 30, and flip-up door 40 together form a housing space for accommodating the liquid oxygen tank.

[0034] The supporting chassis 10 has at least three non-collinear protrusions 60 arranged in a specific layout to define a circle. According to geometric principles, three non-collinear points can define a circle. When there are more than three non-collinear protrusions 60, they are roughly distributed around the center of the liquid oxygen tank's bottom, forming an inner circle. The inner circle formed by the protrusions 60 matches the shape of the liquid oxygen tank's bottom, which is typically circular. When the liquid oxygen tank is placed at the center of the supporting chassis 10, its bottom edge contacts the protrusions 60. The protrusions 60 apply limiting forces to the bottom of the liquid oxygen tank from different directions, preventing horizontal movement and thus achieving stable positioning of the liquid oxygen tank. This design effectively solves the problems of shaking, tipping, and leakage when forklifts handle liquid oxygen tanks, improving the stability and safety of the tank during movement, reducing operational complexity and site requirements, and also reducing costs and safety hazards.

[0035] In some embodiments, the supporting chassis 10 is a plate structure or is formed by arranging and combining multiple pipes.

[0036] The supporting chassis 10 can adopt two structural forms. One is a plate structure, in which the supporting chassis 10 is a single flat plate. This structure has the characteristics of good sealing and can provide a flat and continuous support surface, ensuring that the bottom of the liquid oxygen tank is evenly stressed and avoiding tilting or damage to the liquid oxygen tank due to uneven support. At the same time, the plate structure provides complete support for the bottom of the liquid oxygen tank, effectively distributing the weight of the liquid oxygen tank, reducing the strength requirements of the supporting chassis 10 material, and improving the overall stability and durability.

[0037] Another structure involves the support chassis 10 being formed by an arrangement of multiple tubular components. These components can be round or square tubes, with appropriate spacing determined by actual needs. For example, round tubes can be arranged closely or with appropriate spacing; appropriate spacing ensures sufficient support strength while saving material costs. Square tubes, due to their regular cross-sectional shape, provide higher structural strength and facilitate precise control of assembly dimensions. The support chassis 10 using this tubular arrangement offers cost savings, especially when high airtightness requirements are not necessary. It provides effective support for liquid oxygen tanks at a lower cost, while reducing overall weight for easier movement and transportation.

[0038] In some embodiments, there are four protrusions 60, which are distributed vertically and horizontally.

[0039] The design incorporates four protrusions 60, distributed vertically and horizontally. This distribution balances effective limiting and cost considerations. The four protrusions 60 are positioned at the four cardinal points of the supporting chassis 10, providing comprehensive limiting for the bottom of the liquid oxygen tank. When the liquid oxygen tank is placed at the center of the supporting chassis 10, the four protrusions 60 abut against the bottom of the tank in four directions, effectively preventing horizontal movement and swaying, ensuring stability during movement. Compared to a larger distribution of protrusions 60, the four-protrusion design achieves good limiting while reducing manufacturing and installation costs, simplifying the overall structure, and improving production efficiency and economic benefits.

[0040] In some embodiments, the supporting chassis 10 is square.

[0041] The support chassis 10 is designed in a square shape, which facilitates its use with forklifts. Forklift forks are typically parallel rectangular structures, and the square support chassis 10 better matches the shape of the forklift forks, ensuring that the forklift can smoothly insert into and lift the entire liquid oxygen tank unit. At the same time, the square design, while ensuring sufficient support area for the liquid oxygen tank, optimizes the dimensions so that the area of ​​the support chassis 10 exactly meets the minimum lifting area required by the forklift, thereby saving material costs. Furthermore, the regular shape of the square support chassis 10 facilitates the rational planning of storage space, reduces space occupancy, and allows for the neat stacking of multiple liquid oxygen tank units in warehouses or transport vehicles, improving space utilization.

[0042] In some embodiments, the flip door 40 is hinged to a structural rod 20 in the horizontal direction.

[0043] The flip-up door 40 is horizontally hinged to a structural rod 20, allowing it to easily open outwards. When the liquid oxygen tank needs to be placed in or removed, simply opening the flip-up door 40 creates a spacious opening, facilitating direct insertion or removal from the side – a simple and quick operation. Compared to other hinge methods, the horizontal hinge does not occupy additional horizontal space, saving operating space and making the entire device more compact. Simultaneously, when closed, the flip-up door 40 fits snugly against the structural rods 20 on both sides, maintaining the integrity of the liquid oxygen tank assembly and preventing the tank from accidentally moving out during transport.

[0044] In some embodiments, the upper surface of the supporting chassis 10 is provided with an anti-slip layer 70.

[0045] The upper surface of the support chassis 10 is provided with an anti-slip layer 70, which is made of rubber. Rubber has good anti-slip properties, which can increase the friction between the bottom of the liquid oxygen tank and the support chassis 10. Combined with the limiting effect of the protrusion 60, it further improves the stability of the liquid oxygen tank. During movement, even if subjected to a certain external impact or bump, the liquid oxygen tank is unlikely to slide or tilt, thereby effectively reducing the safety hazards caused by the movement of the liquid oxygen tank. In addition, the rubber anti-slip layer 70 also has a certain shock absorption and cushioning effect, which can reduce the impact force of the liquid oxygen tank on the support chassis 10 and extend the service life of the device.

[0046] In some embodiments, the protrusion 60 is slidably locked to the supporting chassis 10.

[0047] The protrusion 60 and the supporting chassis 10 are connected by a sliding locking mechanism. One common sliding locking structure involves a T-shaped groove on the supporting chassis 10, with a matching T-shaped slider at the bottom of the protrusion 60. The protrusion 60 slides within the groove via the T-shaped slider. After adjustment to the appropriate position, a locking screw is passed through the locking hole in the groove to fix the protrusion 60 to the supporting chassis 10. Another structure involves a dovetail groove on the supporting chassis 10, with a dovetail slider at the bottom of the protrusion 60. The slider slides within the dovetail groove, and tightening the pressure plate bolts presses the pressure plate against the protrusion 60, achieving fixation. These sliding locking structures allow the protrusion 60 to be flexibly adjusted according to different sizes of liquid oxygen tanks, improving the versatility and adaptability of the device and facilitating quick customization or adjustment of the liquid oxygen tank device specifications by users according to actual needs.

[0048] In some embodiments, the supporting base 10 has the same number of strip-shaped through slots 80 as the protrusions 60. These slots 80 are arranged below the protrusions 60 along the diameter of the circle formed by the protrusions 60. The bottom surface of each protrusion 60 has a downwardly extending threaded post 81 that can pass through the strip-shaped through slot 80. The limiting effect of the strip-shaped through slot 80 allows the protrusions 60 to slide along the length of the strip-shaped through slot 80 and is threadedly connected to the threaded post 81 by a nut 82, thus locking the protrusions 60 at a certain point in the strip-shaped through slot 80. The supporting base 10 has the same number of strip-shaped through slots 80 as the protrusions 60, and these slots 80 are arranged below the protrusions 60 along the diameter of the circle formed by the protrusions 60. The bottom surface of the protrusion 60 is provided with a downwardly extending threaded post 81. After passing through the strip-shaped groove 80, the threaded post 81 is threadedly connected to the threaded post 81 by a nut 82, locking the protrusion 60 at a certain point in the strip-shaped groove 80. To adjust the position of the protrusion 60, first loosen the nut 82, slide the protrusion 60 along the length of the strip-shaped groove 80 to the appropriate position, and then tighten the nut 82 to complete the fixation. For multiple protrusions 60, the position of each protrusion 60 can be adjusted individually to adapt to the bottom shape of liquid oxygen tanks of different sizes. For example, for smaller liquid oxygen tanks, the protrusion 60 can be moved towards the center to reduce the diameter of the inner circle; for larger liquid oxygen tanks, the protrusion 60 can be moved outward to increase the diameter of the inner circle. This design greatly improves the practicality and compatibility of the device, enabling it to adapt to various specifications of liquid oxygen tanks and meet the diverse needs of different users. Furthermore, the strip-shaped groove 80 is provided with graduation lines. The strip-shaped channel 80 is equipped with graduation lines, which are evenly distributed along the length of the channel 80. When adjusting the position of the protrusions 60, the operator can quickly determine the distance each protrusion 60 should move based on the graduation lines, ensuring that all protrusions 60 are adjusted to the same radius position, thus forming a complete circular limiting structure. The graduation lines improve the accuracy and consistency of operation, reduce the problem of unstable placement of liquid oxygen tanks caused by visual errors or inaccurate manual adjustments, make the adjustment process simpler and faster, facilitate on-site operators to quickly get started, and improve work efficiency.

[0049] In some embodiments, the supporting chassis 10, structural rod 20, structural frame 30, tilting door 40, and protrusion 60 are all made of stainless steel. Stainless steel has excellent corrosion resistance, resisting the erosion from the low-temperature and humid environment that the liquid oxygen tank may release during use, thus extending the service life of the device. At the same time, stainless steel has high strength, capable of withstanding the weight of the liquid oxygen tank and various external impacts during movement, ensuring the structural stability and safety of the entire device. Furthermore, the smooth surface of stainless steel is easy to clean, meeting industrial hygiene standards, facilitating daily maintenance and reducing maintenance costs.
