Description

Technical Field

[0001] This utility model relates to the field of hydrogen transportation technology, specifically a hydrogen transportation device. Background Technology

[0002] Traditional hydrogen transportation methods mostly involve pipeline transport or hydrogen cylinder transportation. Among these, hydrogen cylinder transportation is widely used in industrial production, scientific research, and other fields due to its high flexibility and wide applicability. However, there are many safety hazards during the transportation of hydrogen cylinders. On the one hand, hydrogen cylinders are high-pressure containers, and the consequences of leakage or damage are unimaginable. On the other hand, traditional hydrogen cylinder transportation devices lack effective fixing and shock absorption measures, which can easily cause the hydrogen cylinders to shake or collide during transportation, increasing safety risks.

[0003] When transporting hydrogen, different capacities of hydrogen cylinders are needed depending on the demand of different users. However, the existing conveying devices use fixed wedges for clamping, which can only accommodate hydrogen cylinders of a specified capacity and meet the transportation needs of a single customer. If it is necessary to transport hydrogen cylinders required by other customers, the wedges need to be replaced. Frequent replacement of the wedges will not only increase the burden on the staff, but also increase the time required for transportation.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a hydrogen delivery device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a hydrogen delivery device, including a fixing component and a shock-absorbing component, characterized in that: the fixing component includes a fixing block and a driving component, the fixing block is arranged in a circular array with the axis of the fixing component as the center, and multiple fixing blocks are equally spaced, and the fixing blocks are rotatably connected to the driving component.

[0007] Furthermore, the driving component includes a frame with multiple guide grooves obliquely formed on the frame. A limiting ring is rotatably connected in the frame, and multiple limiting grooves are vertically formed on the limiting ring. There is partial overlap between the corresponding guide grooves and limiting grooves. A linkage rod is inserted into the fixing block. The fixing block is rotatably connected between the frame and the limiting ring through the linkage rod. The number of guide grooves, limiting grooves, and fixing blocks corresponds. The linkage rod is located at the intersection of the corresponding guide groove and limiting groove, and its two ends protrude from the guide groove and the limiting groove, respectively.

[0008] Furthermore, a limiting block is fixedly connected to the frame, the inner diameter of the limiting block is slightly smaller than the outer diameter of the limiting ring, the limiting ring is rotatably connected between the limiting block and the fixed block, and both ends of the linkage rod are engaged with elastic buckles, which are respectively set on the outside of the guide groove and the limiting groove.

[0009] Furthermore, the fixing component also includes a positioning component, which includes a pull rod fixedly connected to one side of the limiting ring. The pull rod has a threaded through hole, and a screw is threadedly connected to the threaded through hole. An abutment block is rotatably connected to one end of the screw near the frame. An abutment groove is provided on the frame, allowing the abutment block to slide back and forth and along the direction of the abutment groove. A through groove adapted to the abutment groove is provided on the limiting groove. The abutment block is disposed in the abutment groove. In the initial state, the screw is tightened in the limiting ring, and the abutment block abuts against the abutment groove.

[0010] Furthermore, there are two fixing components, which are symmetrically arranged on the top surface of the movable seat along the front and rear central axis. The fixing component located at the rear does not have a positioning component, and the pull rods of the two fixing components are connected by an extension rod.

[0011] Furthermore, the shock absorption assembly includes a main damper whose two ends are fixedly connected to the bottom surface of the frame and the top surface of the movable seat, respectively. A main buffer spring is sleeved on the outer side of the main damper. Two main dampers are arranged in a linear array on the left and right central axes of the bottom surface of the frame.

[0012] Furthermore, the shock absorption assembly also includes two connecting rods, which are symmetrically arranged on both sides of the bottom surface of the frame along the left and right central axes of the frame. One end of each connecting rod is fixedly connected to an upper rotating shaft that is rotatably connected to the bottom surface of the frame, and the other end of each connecting rod is fixedly connected to a lower rotating shaft. The lower rotating shaft is rotatably connected to a slider. The inner sides of the two sliders are respectively fixedly connected to the two ends of a secondary damper and a secondary buffer spring. The secondary buffer spring is sleeved around the outer wall of the secondary damper. The top surface of the movable seat has a slot that allows the slider to slide laterally only, and the slider is slidably connected in the slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting up a fixing component, the limiting ring can be rotated by holding the pull rod, thereby centering and adjusting the channel formed by the sharp corner of the fixing block.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] A hydrogen delivery device includes a fixed component 1, a movable seat 3 is provided below the fixed component 1, and casters 301 are provided at the four corners of the bottom surface of the movable seat 3. The fixed component 1 and the movable seat 3 are connected by a shock-absorbing component 2.

[0034] Please see Figure 1-3 This utility model provides a technical solution: the fixing component 1 includes a frame 101 that can only slide vertically, a plurality of guide grooves 1011 are obliquely formed on the frame 101, a limiting ring 102 is rotatably connected in the frame 101, a plurality of limiting grooves 1021 are vertically formed on the limiting ring 102, and there is partial overlap between the corresponding guide grooves 1011 and limiting grooves 1021, a plurality of fixing blocks 103 are provided between the frame 101 and the limiting ring 102, the inner side of the fixing block 103 is hollow metal, and the outer side is rubber. The rubber sleeve's strength is guaranteed by the metal, preventing it from easily deforming. Its texture is improved by the rubber sleeve, preventing scratches on the outside of the hydrogen cylinder and ensuring a tighter contact with the outside of the hydrogen cylinder. The guide groove 1011, the limiting groove 1021, and the fixing block 103 correspond in number. A linkage rod 104 is inserted into the fixing block 103. The linkage rod 104 is located at the intersection of the corresponding guide groove 1011 and the limiting groove 1021, with its two ends protruding from the guide groove 1011 and the limiting groove 1021, respectively.

[0035] By adopting the above design, when hydrogen cylinders need to be transported, the limiting ring 102 can be rotated counterclockwise, causing the intersection of the guide groove 1011 and the limiting groove 1021 to move away from the axis of the fixing component 1. This causes the tip of the fixing block 103 to move centrifugally around the axis of the fixing component 1, thereby opening the inner channel of the frame 101 and the limiting ring 102. At this time, the hydrogen cylinder is placed in, and then the limiting ring 102 is rotated clockwise, causing the tip of the fixing block 103 to move centripetally around the axis of the fixing component 1. This causes the hydrogen cylinder to be fixed against the side. This allows the device to freely adjust the amplitude of clockwise and counterclockwise rotation of the limiting ring 102, and adjust the distance between the side of the tip of the fixing block 103 and the axis of the fixing component 1, thereby adapting to the outer diameter of hydrogen cylinders of different capacities and improving the versatility of the device.

[0036] For details, please refer to Figure 1-4 A limiting block 1012 is fixedly connected to the frame 101. The frame 101 and the limiting block 1012 are connected by an arc plate. There are multiple arc plates with gaps larger than the fixed block 103 between them. The inner diameter of the limiting block 1012 is slightly smaller than the outer diameter of the limiting ring 102. The limiting ring 102 is rotatably connected between the limiting block 1012 and the fixed block 103. Both ends of the linkage rod 104 are engaged with elastic buckles 1041. The elastic buckles 1041 are respectively set on the outside of the guide groove 1011 and the limiting groove 1021.

[0037] By adopting the above design, when the fixing block 103 needs to be cleaned, or when the rubber sleeve on the fixing block 103 is worn after long-term use, the elastic buckles 1041 at both ends of the linkage rod 104 can be removed, and then the linkage rod 104 can be pulled out from the fixing block 103. The linkage rod 104 can then be removed through the gap between the arc plates, and the rubber sleeve on the fixing block 103 can be replaced, or the surface of the fixing block 103 can be cleaned.

[0038] Further, see Figure 1 and Figure 2 The fixing component 1 also includes a positioning component, which includes a pull rod 105 fixedly connected to one side of the limiting ring 102. The pull rod 105 has a threaded through hole, with clockwise rotation being the forward direction and counterclockwise rotation being the backward direction. A screw 106 is threadedly connected to the threaded through hole. An abutment block 1061 is rotatably connected to one end of the screw 106 near the frame 101. An abutment groove 1062 is provided on the frame 101, allowing the abutment block 1061 to slide back and forth and along the opening direction of the abutment groove 1062. A through groove adapted to the abutment groove 1062 is provided on the limiting groove 1021. The abutment block 1061 is disposed in the abutment groove 1062. In the initial state, the screw 106 is screwed into the limiting ring 102, and the abutment block 1061 abuts against the abutment groove 1062.

[0039] By adopting the above design, the operator can hold the lever 105 to rotate the limiting ring 102. By increasing the gripping area, it is more convenient to apply force when rotating. When it is necessary to rotate the limiting ring 102, the screw 106 can be rotated clockwise so that the abutment block 1061 no longer abuts against the abutment groove 1062. Then the limiting ring 102 can be rotated to clamp and fix the hydrogen cylinder. After clamping is completed, the screw 106 can be rotated counterclockwise so that the screw 106 abuts against the abutment block 1061 and makes it contact the abutment groove 1062, thereby fixing the limiting ring 102 so that it cannot be rotated.

[0040] Furthermore, see Figure 1 There are two fixing components 1. The two fixing components 1 are symmetrically arranged on the top surface of the movable seat 3 along the front and rear central axis. The fixing component 1 located at the rear does not have a positioning component. The pull rods 105 of the two fixing components 1 are connected by an extension rod.

[0041] By adopting the above design, the device can clamp and fix the hydrogen cylinder from both the front and rear sides. By increasing the clamping position, the stability of clamping is improved. When the front pull rod 105 is rotated to adjust the limiting ring 102, the extension rod will drive the rear pull rod 105 to rotate together, thereby realizing the synchronous adjustment of the front and rear limiting rings 102. When the limiting ring 102 is fixed, the rear limiting ring 102 will also be fixed.

[0042] Based on the above embodiments, please refer to Figure 1 and Figure 2 The present invention provides a technical solution: the shock absorption component 2 includes a main damper 201 whose two ends are fixedly connected to the bottom surface of the frame 101 and the top surface of the movable seat 3 respectively. A main buffer spring 2011 is sleeved on the outer side of the main damper 201. Two main dampers 201 are arranged in a linear array on the left and right central axes of the bottom surface of the frame 101.

[0043] By adopting the above design, when the hydrogen cylinder is transported on a bumpy road, the main buffer spring 2011 can absorb and convert the impact force generated by the shaking, thus playing a buffering role. The main damper 201 can increase the impact force loss in the process of the main buffer spring 2011 converting the impact force, thereby achieving the shock absorption effect and protecting the hydrogen cylinder during transportation.

[0044] Further, see Figure 1 and Figure 2 The shock absorption assembly 2 also includes two connecting rods 203. The connecting rods 203 are symmetrically arranged on both sides of the bottom surface of the frame 101 along the left and right central axes of the frame 101. One end of the connecting rod 203 is fixedly connected to an upper rotating shaft 2031 that is rotatably connected to the bottom surface of the frame 101. The other end of the connecting rod 203 is fixedly connected to a lower rotating shaft 2032. The lower rotating shaft 2032 is rotatably connected to a slider 2022. The inner sides of the two sliders 2022 are respectively fixedly connected to the two ends of the auxiliary damper 202 and the auxiliary buffer spring 2021. The auxiliary buffer spring 2021 is sleeved around the outer wall of the auxiliary damper 202. The top surface of the moving seat 3 is provided with a slot that allows the slider 2022 to slide laterally. The slider 2022 is slidably connected in the slot.

[0045] By adopting the above design, when encountering more bumpy road sections, if the main damper 201 and the main buffer spring 2011 cannot effectively achieve the shock absorption effect, the upper rotating shaft 2031 will move downward due to the bumps. Since the length of the connecting rod 203 remains unchanged, the lower rotating shaft 2032 will move away from the fixed component 1 along with the slider 2022. The sliding of the slider 2022 will stretch the secondary buffer spring 2021, causing it to deform and absorb the impact force, thereby achieving further buffering. In addition, the secondary damper 202 will increase the loss of the secondary buffer spring 2021 during the conversion process, achieving a further shock absorption effect, thereby ensuring the safety of the hydrogen cylinder.

[0046] Working principle:

[0047] In use, first rotate the screw 106 counterclockwise so that the abutment block 1061 no longer abuts against the abutment groove 1062. At this time, the pull rod 105 can be pushed clockwise or counterclockwise to drive the limiting ring 102 to rotate. With the axis of the fixing component 1 as the center, the size of the channel formed by the sharp corner of the fixing block 103 is centered and adjusted to adapt to the outer diameter of hydrogen cylinders of different capacities, and to perform adaptive clamping. After clamping, the screw 106 can be rotated clockwise again so that the abutment block 1061 abuts against the abutment groove 1062, thus completing the clamping and fixing of the hydrogen cylinder. Then, the hydrogen cylinder can be transported by the moving seat 3 and the universal wheel 301.

[0048] During transportation, if the hydrogen cylinder encounters bumpy road sections and shakes up and down, the main buffer spring 2011 can absorb and convert the impact force generated by the shaking, thus playing a buffering role. The main damper 201 can increase the impact force loss in the process of the main buffer spring 2011 converting the impact force, thereby achieving a shock absorption effect and protecting the hydrogen cylinder during transportation. The upper rotating shaft 2031 will also move downward due to bumps. Since the length of the connecting rod 203 remains unchanged, the lower rotating shaft 2032 will move away from the fixed component 1 along with the slider 2022. The sliding of the slider 2022 will stretch the secondary buffer spring 2021, causing it to deform and absorb the impact force, thereby achieving further buffering. The secondary damper 202 will increase the loss in the conversion process of the secondary buffer spring 2021, achieving a further shock absorption effect, thereby ensuring the safety of the hydrogen cylinder.

[0049] Once you reach the designated position, rotate the cylinder counterclockwise again to remove the hydrogen cylinder.
