Description
Technical Field
[0001] This utility model relates to the field of gas cylinder transportation technology, specifically to a fixed device for transporting hydrogen energy gas cylinders. Background Technology
[0002] Hydrogen energy refers to the chemical energy released by the chemical reaction of hydrogen and oxygen. It is a clean secondary energy source with advantages such as high energy density, high calorific value, wide availability, storability, renewability, combustibility, zero pollution, and zero carbon emissions. It helps to solve problems such as energy crisis and environmental pollution. Hydrogen energy transportation usually requires the use of hydrogen cylinders.
[0003] For example, Chinese Patent (CN220375129U) discloses a hydrogen energy cylinder transportation and fixing device, including a base plate and a top plate. Two first support rods are fixed to one side of the upper part of the base plate, and two second support rods are fixed to the other side of the upper part of the base plate. Each first support rod has a first slot at its upper end, and a first insert rod is slidably disposed within each first slot. One side of the top plate is rotatably connected to the upper part of the two first insert rods. Second insert rods are fixed to both ends of the top plate away from the first insert rods. Each second support rod has a second slot at its upper end, and the second insert rod is adapted to the second slot. A locking mechanism is provided between the top plate and the first and second support rods. Multiple placement slots are equidistantly opened on the upper part of the base plate, and multiple limiting openings are equidistantly opened on the top plate, with each limiting opening corresponding to one of the placement slots. This utility model achieves separation and limiting of multiple hydrogen cylinders, avoiding collisions and safety threats during transportation.
[0004] However, the aforementioned devices cannot be adapted to gas cylinders of different specifications. When faced with gas cylinders of different lengths, they may not fit well and may fail to secure them properly. This could lead to the gas cylinder tilting, sliding, or tipping over during use. The equipment is only applicable to gas cylinders of a specific specification. For gas cylinder types with significant variations, users may need to purchase or adjust different securing devices for each type of gas cylinder, increasing costs and maintenance difficulty. To address the above problems, a hydrogen energy gas cylinder transportation securing device is proposed to provide a solution. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a hydrogen energy cylinder transportation and fixing device. This solves the problem that current devices are not compatible with cylinders of different specifications. When faced with cylinders of different lengths, they may not be able to fit well and may fail to secure properly, potentially causing the cylinders to tilt, slide, or tip over during use. Furthermore, the device is only suitable for cylinders of a specific specification. For cylinder types with significant variations, users may need to purchase or adjust different fixing devices for each type, increasing costs and maintenance difficulties.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hydrogen energy hydrogen cylinder transportation and fixing device, including a base plate, a movable component arranged below the base plate, a fixed frame fixedly connected above the base plate, movable guide rails arranged on both the front and rear sides of the fixed frame, limit blocks fixedly connected to the left and right ends of the two movable guide rails, a second threaded rod rotatably connected to the middle position inside the fixed frame, and fixed components arranged on the left and right sides above the fixed frame. The bottom of the left fixed component is threadedly connected to the second threaded rod through a threaded block, and the left fixed component is slidably connected to the movable guide rail through a sliding block. The right fixed component is fixedly connected to the right side of the fixed frame, and the right end of the second threaded rod passes through the right side of the fixed frame and is fixedly connected to a handwheel.
[0007] Preferably, protective frames are fixedly connected to the left and right sides above the fixed frame, and at least two protective strips are fixedly connected to the front and back sides of the two sets of protective frames.
[0008] Preferably, the fixing component includes a connecting frame, and at least two placement blocks are fixedly connected to the bottom surface inside the connecting frame, with the upper surface of the placement blocks recessed inward.
[0009] Preferably, the connecting frame is fixedly connected with a threaded sleeve of the same number as the placement blocks. The threaded sleeve is threadedly connected with a first threaded rod. The bottom of the first threaded rod is rotatably connected with an arc-shaped locking block. The upper end of the first threaded rod is fixedly connected with a rotating handle.
[0010] Preferably, the moving component includes a first fixed plate and a second fixed plate. A first rotating shaft is rotatably connected to the upper center of the first fixed plate, and a second rotating shaft is rotatably connected to the upper center of the second fixed plate. The tops of the first and second rotating shafts are fixedly connected to the bottom surface of the base plate, and a traction rod is rotatably connected to the left side of the first fixed plate.
[0011] Preferably, a first connecting rod is rotatably connected to the rear bottom side of the first fixing plate, the end of the first connecting rod is rotatably connected to the front bottom side of the second fixing plate, and a second connecting rod is rotatably connected to the front top side of the first fixing plate. The second connecting rod is rotatably connected to the rear top side of the second fixing plate, and the first connecting rod and the second connecting rod form an "X" shape.
[0012] Preferably, the bottom of both the first fixing plate and the second fixing plate are rotatably connected to a rotating rod via a connector, and both ends of the two rotating rods are fixedly connected to a movable wheel.
[0013] Compared with the prior art, the advantages of this utility model are:
[0014] 1. This utility model drives the second threaded rod to rotate by turning the handwheel, and the left-side fixing component moves left and right along the moving guide rail, thereby adapting to hydrogen cylinders of different lengths. Users do not need to purchase special equipment for different specifications of gas cylinders. This flexible adaptability saves equipment space and improves the flexibility of use. It is highly adaptable and can meet diverse needs. The fixing position can be quickly adjusted by turning the handwheel, making the operation simpler and more efficient. Operators do not need to waste time disassembling and replacing fixing devices of different specifications. It can quickly adapt to hydrogen cylinders of different lengths, which helps to improve work efficiency, especially in situations where frequent operation of hydrogen cylinders is required.
[0015] 2. This utility model incorporates a moving component. When turning, the traction rod drives the first fixed plate to rotate around the first pivot. At this time, through the first and second connecting rods, the second fixed plate rotates in the opposite direction relative to the first fixed plate, thereby reducing the turning radius. By reducing the turning radius, the transport device can rotate in a smaller space, avoiding the waste of space caused by excessive turning space. This allows the equipment to work more flexibly in a limited operating space, making it suitable for confined environments or places with limited space. Attached Figure Description

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0024] Reference Figure 1-5 As shown, a hydrogen energy cylinder transportation and fixing device includes a base plate 1, a movable component 8 is arranged below the base plate 1, a fixed frame 2 is fixedly connected above the base plate 1, movable guide rails 3 are arranged on both the front and rear sides of the fixed frame 2, and limit blocks 4 are fixedly connected to both ends of the two movable guide rails 3. The limit blocks 4 limit the stroke of the fixing component 5 to prevent overtravel from damaging the threaded mechanism and extend the service life of the equipment. A second threaded rod 9 is rotatably connected to the middle position inside the fixed frame 2. The fixing components 5 are arranged on the left and right sides above the fixed frame 2. The bottom of the left fixing component 5 is threadedly connected to the second threaded rod 9 through a threaded block, and the left fixing component 5 is slidably connected to the movable guide rail 3 through a sliding block. The right fixing component 5 is fixedly connected to the right side above the fixed frame 2. The right end of the second threaded rod 9 passes through the right side of the fixed frame 2 and is fixedly connected to a handwheel 10.
[0025] Furthermore, protective frames 6 are fixedly connected to the left and right sides above the fixed frame 2. At least two protective strips 7 are fixedly connected to the front and back sides of the two sets of protective frames 6. The protective frames 6 and the protective strips 7 form a physical barrier to prevent the gas cylinder from lateral collision. The protective strips 7 can adopt a rubber-metal composite structure to ensure strength and absorb collision energy.
[0026] Specifically, the fixing component 5 includes a connecting frame 501, and at least two placement blocks 502 are fixedly connected to the bottom surface inside the connecting frame 501. The upper surface of the placement blocks 502 is recessed inward.
[0027] Specifically, the same number of threaded sleeves 503 as the placement blocks 502 are fixedly connected above the connecting frame 501. The threaded sleeve 503 is internally threaded with a first threaded rod 504. The bottom of the first threaded rod 504 is rotatably connected with an arc-shaped locking block 505. The upper end of the first threaded rod 504 is fixedly connected with a rotating handle 506. The thread self-locking characteristic ensures that the clamping force is constant and maintains reliable clamping force under vibration environment. The inner side of the arc-shaped locking block 505 is provided with anti-slip texture to prevent the gas cylinder from sliding.
[0028] Furthermore, the moving component 8 includes a first fixed plate 801 and a second fixed plate 802. A first rotating shaft 803 is rotatably connected to the upper center of the first fixed plate 801, and a second rotating shaft 804 is rotatably connected to the upper center of the second fixed plate 802. The tops of the first rotating shaft 803 and the second rotating shaft 804 are fixedly connected to the bottom surface of the base plate 1. A traction rod 809 is rotatably connected to the left side of the first fixed plate 801. The traction rod 809 can be connected to an external moving mechanism for dragging the device to move, or it can be pulled by personnel.
[0029] Furthermore, a first connecting rod 807 is rotatably connected to the rear bottom side of the first fixed plate 801, and the end of the first connecting rod 807 is rotatably connected to the front bottom side of the second fixed plate 802. A second connecting rod 808 is rotatably connected to the front upper side of the first fixed plate 801, and the second connecting rod 808 is rotatably connected to the rear upper side of the second fixed plate 802. The first connecting rod 807 and the second connecting rod 808 form an "X" shape. The "X" shaped linkage mechanism enables the front and rear wheels to automatically coordinate the steering angle, and the minimum turning radius is only 0.8 times the wheelbase.
[0030] Furthermore, the bottom of both the first fixed plate 801 and the second fixed plate 802 are rotatably connected to rotating rods 805 via connectors, and both ends of the two rotating rods 805 are fixedly connected to movable wheels 806.
[0031] Working principle: First, based on the length of the gas cylinder, the second threaded rod 9 is driven to rotate by turning the handwheel 10. The left fixed component 5 moves left and right along the moving guide rail 3 to adapt to hydrogen cylinders of different lengths. Then, the gas cylinder is placed between the placement blocks 502 in the two fixed components 5. Then, the first threaded rod 504 is driven to rotate by rotating the handle 506. Through the threaded engagement with the threaded sleeve 503, the arc-shaped locking block 505 moves vertically to engage with the recessed placement block 502, which can stably clamp the gas cylinder. When turning, the traction rod 809 drives the first fixed plate 801 to rotate around the first rotating shaft 803. At this time, through the first connecting rod 807 and the second connecting rod 808, the second fixed plate 802 rotates in the opposite direction relative to the first fixed plate 801, thereby reducing the turning radius.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
