Description

Technical Field

[0001] The utility model relates to the field of hydrogen cylinder transportation, in particular to a hydrogen cylinder storage and transportation device. Background Art

[0002] A hydrogen cylinder is a container used to store and transport hydrogen. Most of the existing hydrogen cylinders are placed vertically and closely together in the open rear compartment of a truck. An outer frame is used to wrap all the hydrogen cylinders and limit their positions to prevent them from shaking and colliding with each other. However, the limiting structure of this outer frame cannot limit each hydrogen cylinder independently. Adjacent hydrogen cylinders can easily collide with each other due to the bumps and shaking of the vehicle, posing a high risk of accidents that may cause combustion and explosion.

[0003] The Chinese patent with authorization announcement number CN216233745U provides a limiting device for transporting hydrogen cylinders in low-carbon parks. The solution is achieved by sliding a clamping plate with arc grooves on a base. Except for the two outermost clamping plates which have arc grooves on only one side, the other clamping plates have arc grooves on both sides to increase the number of gas cylinders that can be clamped. After all the clamping plates are installed and fixed, each hydrogen cylinder is also installed in place on the limiting device. The hydrogen cylinder is clamped by two adjacent arc grooves to prevent the hydrogen cylinder from shaking violently, so that it can still be used on bumpy roads.

[0004] However, the multiple limiting holes and arc grooves on the clamping plate in this scheme are of the same size, so that this scheme can only fix hydrogen cylinders of a single size. In actual production or transportation, the processing or temperature of the hydrogen cylinders may cause dimensional fluctuations or errors. Moreover, there will always be deformation during use. Minor deformation within a safe range will not affect the continued use of the hydrogen cylinder or frame. During the circulation and loading of the hydrogen cylinders, the loading position is randomly assigned, that is, the installation position of the hydrogen cylinder is not fixed and needs to be adapted to different installation holes or grooves. It is impossible to clamp all hydrogen cylinders at the same time. In reality, there are many different models of hydrogen cylinders with different bottle thicknesses. This scheme cannot meet the needs of fixing hydrogen cylinders of different sizes. Therefore, a hydrogen cylinder storage and transportation device is proposed to address the above problems.

[0029] See also Figure 1-Figure 3An embodiment of a hydrogen cylinder storage and transportation device, the hydrogen cylinder transportation device includes a frame 100, the frame 100 can be made of metal, a plurality of groups of guide slide assemblies 200 are arranged in the frame 100, each group of guide slide assemblies 200 includes four parallel guide pillars 210, wherein the guide pillars 210 play a guiding role and constrain the movement of the clamping plate 310. A plurality of clamping plate groups 300 are arranged in the extension direction of each group of guide slide assemblies 200, and a plurality of clamping plate groups 300 can meet the installation requirements of multiple hydrogen cylinders. Each clamping plate group 300 includes a pair of clamping plates 310 arranged opposite to each other, and sliding fitting holes 320 are provided on the clamping plates 310 corresponding to the four guide pillars 210, and each sliding fitting hole 320 is slidingly matched with the four guide pillars 210, and the clamping plates 310 are also provided with two threaded fitting holes 330 symmetrical about the center of the clamping plates 310. With this arrangement, the clamping plates 310 The center of the combined force of the driving screw 400 on the clamping plate 310 is located at the center of the clamping plate 310, which is conducive to preventing the jamming phenomenon under the eccentric clamping situation; wherein each clamping plate 310 is provided with two or four threaded matching holes, and the combined force of each threaded matching hole 330 is located at the center of the clamping plate 310, wherein when two threaded matching holes are provided, they can be located at the diagonal position of the clamping plate 310, and when four threaded matching holes are provided, they can be located at the four corners of the clamping plate 310, that is, there are two pairs of threaded matching holes 330 symmetrical about the center of the clamping plate 310. The four corners of the frame 100 can also be provided with multiple hooks to further facilitate the oblique pull fixation. The four corners of the frame 100 can also be provided with connecting bolts to facilitate bolt connection and fixation on the vehicle body or the fixed bracket.

[0030] Among them, the spiral matching holes on the same splint 310 in each splint group 300 have the same rotation direction, and the spiral matching holes of different splints 310 in each splint group 300 have opposite rotation directions. The threaded matching holes 330 on each splint 310 are spirally matched with the spiral segments on the corresponding driving screw 400 arranged on the frame 100, and the end of the driving screw 400 is rotatably supported on the frame 100. The rotatable structure can be realized based on the bearing support structure. Several sections of spiral rod segments 410 with different rotation directions are alternately arranged on the driving screw 400, and the facing sides of the two splints 310 are hinged with at least one pair of openable and closable clamping plates 340. Specifically in this embodiment, a hinge shaft 341 is arranged through the edge of the clamping plate 340, and the hinge shaft 341 extends on both sides of the clamping plate 340 in the height direction. The splint 310 is provided with a pair of hinge supports 311 corresponding to the hinge shaft, and the hinge supports 311 are hinged to the corresponding ends of the hinge shaft 341.

[0031] A space 500 for clamping the gas cylinder is formed between the two clamping plates 340, and a spring 600 is arranged between the back of the clamping plate 340 and the end surface of the corresponding clamping plate 310, so that the clamping plate 340 has a tendency to flip. The spring can be a cylindrical compression spring, and the two ends of the spring 300 can be connected to the clamping plate 340 and the clamping plate respectively, and can also keep the clamping plate 340 open at a certain degree, so as to facilitate the placement of the hydrogen cylinder.

[0032] The surface of the clamping plate 340 is provided with a plastic layer, which can prevent impact, wear and scratches on the hydrogen cylinder, and reduce noise during loading. The bottom of the frame 100 is provided with a bottom plate 110, and the bottom plate 110 is provided with a positioning hole, through which the hydrogen cylinder can be positioned. In the early stage of clamping, the position of the hydrogen cylinder is centered to avoid the driving screw 400 pushing the hydrogen cylinder, so that the hydrogen cylinder is centered, which can reduce the load of the driving screw 400. Of course, the positioning hole can also limit the bottom of the hydrogen cylinder to prevent movement.

[0033] A hydrogen cylinder is a container for storing and transporting hydrogen. Due to the high energy density and flammability of hydrogen, the use and management of hydrogen cylinders require special attention and safety measures. When storing and transporting hydrogen, strict safety standards and regulations must be followed to ensure safety and prevent accidents. In this embodiment, in the clamping plate group 300, a space 500 for placing the hydrogen cylinder is formed between the two clamping plates 340. A hydrogen cylinder can be placed in the space 500. Because the clamping plate 340 is always clamped on the side wall of the hydrogen cylinder under the action of the spring 600, the compression degree of the spring 600 can be adjusted by adjusting the spacing of the clamping plates 310, and then the clamping force can be adjusted. Of course, it can also be applied to the clamping of hydrogen cylinders with different diameters or different size fluctuations. The spacing between the two clamping plates 310 is continuously adjusted to reduce the clamping space 500 until a suitable clamping force is reached, which has a high tolerance. The utility model can be applied to hydrogen cylinders of various sizes and has a good fixing effect. The 300 pieces of the splint groups in different columns can be adjusted individually, so that the device can load hydrogen cylinders of multiple different sizes at one time. That is, different groups of guide slide assemblies 200 can respectively correspond to hydrogen cylinders with large size differences. The clamping spaces in each group of guide slide assemblies 200 can adapt to the adaptive clamping of each gas cylinder with a smaller size difference. All hydrogen cylinders can be fixed individually to prevent accidents caused by collisions between hydrogen cylinders during transportation.

[0034] In some embodiments, a toothed pulley is provided at the end of the first of the two driving screw rods 400 extending out of the frame 100 corresponding to each guide sliding assembly 200, and a toothed pulley is provided on the rod body of the second driving screw rod 400 extending out of the frame 100. The two toothed pulleys are connected through a toothed belt transmission. A rocker 420 is provided at the end of any driving screw rod 400 extending out of the frame 100. The rocker 420 can be connected to the end of the driving screw rod by a profile connection to facilitate disassembly. With this structure, the two driving screw rods 400 can be driven to rotate synchronously by shaking one of the rocker rods 420. The toothed belt can realize synchronous transmission of the two driving rods with a constant transmission ratio. At the same time, the synchronization of the movement of the two driving screw rods 400 can prevent jamming on the guide column 210 during the process of pushing the splint 310, and the movement is smoother. Of course, the operating steps can also be reduced. Only one driving screw rod 400 needs to be rotated to complete the clamping of the hydrogen cylinder.

[0035] In some embodiments, a limit block 350 is provided on the side portion of the back of the clamping plate 340 away from the flip axis. By providing the limit block 350, when the spring 600 is compressed to the limit position, a trapezoidal space 500 is formed between the two clamping plates 340. When individual hydrogen cylinders are subjected to lateral loads under extreme conditions, they can still be confined in the trapezoidal space 500, and the edges of the two clamping plates 340 are limited in the space 500 to prevent further deflection and to prevent impact on the guide sliding assembly 200 or the driving screw 400.

[0036] In some embodiments, two groups of clamping plates 340 are provided on each clamping plate 310, and the two groups of clamping plates 340 are arranged at intervals in the height direction of the clamping plate 310. With this structure, each hydrogen cylinder is clamped at two positions in the height direction, and the positioning of the hydrogen cylinder is more stable.

[0037] In some embodiments, a limit ring 401 is provided between adjacent spiral rod segments 410 on the driving screw 400. The limit ring 401 is sleeved on the driving screw 400 and limited by an elastic retaining spring. Through this structure, the limit ring 401 can be inserted into a specified position and then limited by an elastic retaining spring. The limit ring 401 is provided to limit the extreme position of the clamp 310 on the driving screw 400 to prevent it from entering into a screw segment of another rotation direction during use.

[0038] When the above scheme is used to store or transport hydrogen cylinders, the user places hydrogen cylinders of the same size in the same row and places the hydrogen cylinders between a pair of clamping plates 340 so that the hydrogen cylinders are located in the space formed by the multiple clamping plates 340, and then rotates the rocker 420, which drives the drive screw 400 to rotate synchronously. Through the rotation of the bidirectional drive screw 400, the pair of clamping plates 310 are driven to approach each other, and then the pair of clamping plates 310 are driven to slide on the guide column 210, so that the two clamping plates 340 are close to each other and clamp the hydrogen cylinders, and they will rotate on the clamping plates 310 and squeeze the spring 600, which helps to ensure that multiple hydrogen cylinders can be clamped by the corresponding clamping plates 340, thereby ensuring that during transportation, multiple hydrogen cylinders do not contact each other and remain relatively still with the base, thereby improving the safety and stability of the hydrogen cylinders during transportation.

[0039] When unloading the hydrogen cylinder, the user only needs to rotate the rocker 420 in the opposite direction to control the corresponding plurality of clamping plates 340 to move away from each other and release the fixation of the hydrogen cylinder, thereby removing the hydrogen cylinder, which is a relatively convenient process.

[0040] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model fall within the scope of the claims of the utility model and their equivalents, the utility model is also intended to include these modifications and variations.
