Description

Technical Field

[0001] This utility model belongs to the field of hydrogen cylinder reinforcement technology, specifically relating to the reinforcement structure of a multi-layer frame for heavy-duty truck hydrogen cylinders. Background Technology

[0002] Hydrogen cylinders are pressure vessels used to store hydrogen. Based on their material, hydrogen cylinders can be divided into steel cylinders and composite material cylinders. Based on their intended use and the characteristics of the stored gas, hydrogen cylinders can also be divided into industrial hydrogen cylinders, hydrogen fuel cell vehicle storage cylinders, laboratory hydrogen cylinders, etc. Trucks generally need to reinforce hydrogen cylinders to ensure stability when transporting them, so specific reinforcement structures are made for them. However, some existing reinforcement structures often have certain shortcomings in use, so they need to be improved.

[0003] Chinese patent CN217584064U discloses a safety protection device for hydrogen cylinders, comprising an upper shell and a lower shell. The bottom of the upper shell has a first receiving groove for accommodating the hydrogen cylinder, and the top of the lower shell has a second receiving groove for accommodating the hydrogen cylinder. The first receiving groove engages with the top of the hydrogen cylinder, and the second receiving groove engages with the bottom of the hydrogen cylinder. Both the upper and lower shells are made of epoxy resin. Workers insert the hydrogen cylinder into the second receiving groove of the lower shell, then engage the first receiving groove of the upper shell with the top of the hydrogen cylinder, bringing the upper and lower shells together. Epoxy resin has strong adhesive strength, and the upper and lower shells bond together after contact. Epoxy resin is heat-resistant, does not easily deform when heated, and will not compress the hydrogen cylinder due to heat. It also has electrical insulation properties, improving the safety of the hydrogen cylinder.

[0004] However, while the above-mentioned technical solution can achieve the purpose of fixing and protecting the hydrogen cylinder, it also involves protecting it with two shells and connecting multiple fixing plates and bolts. This means that when the hydrogen cylinder is transported to the appropriate location and the hydrogen inside needs to be used, the upper and lower shells need to be separated. This requires workers to disassemble multiple fixing plates and connecting bolts one by one, which is time-consuming and delays the progress of hydrogen transfer. Therefore, it has certain limitations in use. Utility Model Content

A transverse groove 9 is opened inside the first arc-shaped protective cover 18. A steel spring 10 is fixedly connected to one side of the inner wall of the transverse groove 9. One end of the steel spring 10 is fixed... A sliding block 11 is connected, and an inclined block 12 is fixedly connected to the top of the sliding block 11. A slot is opened inside the inclined block 12. An adjustment cavity 13 is fixedly connected to the inner side wall of the horizontal groove 9. A square block 14 is fixedly connected to the bottom end of the inner side wall of the adjustment cavity 13. A compression spring 15 is fixedly connected to the top of the square block 14. A connecting block is fixedly connected to the top of the compression spring 15. A guide rod 16 is fixedly connected to the top of the connecting block. A snap-fit ​​block 17 is fixedly connected to the top of the guide rod 16, and the surface of the snap-fit ​​block 17 penetrates the inside of the slot. The first arc-shaped protective cover 18 and the second arc-shaped protective cover 19 are fixed by the support frame 2. Hydrogen gas is transported by the hydrogen cylinder 4. The rigid spring 10 is installed and fixed by the horizontal groove 9. The inclined block 12 is fixed by the sliding block 11 and can be moved, while the rigid spring 10 is stretched. The square block 14 is fixed inside the adjustment cavity 13. The compression spring 15 is fixed by the square block 14. The connecting block and the guide rod 16 are fixed by the compression spring 15. The locking block 17 moves downward when it is squeezed by the guide rod 16. The top of the locking block 17 is arc-shaped and smooth when it is pushed. The second arc-shaped protective cover 19 has the same groove as the horizontal groove 9 inside, and the structure inside the groove is the same.

[0023] The internal fixed connection of the contact cover 3 consists of two threaded posts 5, and the surface of the threaded posts 5 is threaded with a connecting sleeve 6. The threaded posts 5 enable the connecting sleeve 6 to be quickly connected to them.

[0024] A fixing ring 7 is fixedly connected to the surface of the connecting sleeve 6, and a steel wire rope 8 is fixedly connected to the surface of the fixing ring 7. The bottom end of the steel wire rope 8 is fixedly connected to the inside of the sliding block 11. The fixing ring 7 fixes one end of the steel wire rope 8, making it easier for the abutment cover 3 to be pulled later.

[0025] Example 2:

[0026] Please see Figure 1 and Figure 4As shown, the second arc-shaped protective cover 19 has three rotating ball bearings 20 inside, and the surface of the ball bearings 20 is in contact with the surface of the hydrogen cylinder 4. Two support rods 21 are fixedly connected to the top of the support frame 2, and two fastening bolts are threaded inside the support rods 21, with the threads of the fastening bolts penetrating the interior of both the support frame 2 and the mounting plate 1. The ball bearings 20 facilitate smoother entry of the hydrogen cylinder 4 into the first arc-shaped protective cover 18 and the second arc-shaped protective cover 19, while the support rods 21 enhance the stability of the support frame 2.

[0027] Mounting blocks are fixedly connected to the top and bottom of both sides of mounting plate 1, and two positioning bolts are internally threaded into the mounting blocks. The mounting blocks and positioning bolts make it easy for mounting plate 1 to be stably connected to heavy trucks.

[0028] The working principle of this utility model is as follows: The operator first places the hydrogen cylinder 4 into the circular placement tube formed by the first arc-shaped protective cover 18 and the second arc-shaped protective cover 19. During this process, the surface of the hydrogen cylinder 4 contacts the surface of the ball bearing 20. Then, the operator pushes it forward to place the hydrogen cylinder 4 into the circular placement tube formed by the first arc-shaped protective cover 18 and the second arc-shaped protective cover 19. Next, the operator places the contact cover 3 into contact with one side of the hydrogen cylinder 4, and then screws the two connecting sleeves 6 onto the surface of the threaded post 5. At this time, the operator slides the sliding block 11 inside the transverse groove 9, and the tilting block 12 also moves to the left. At this time, the rigid spring 10 is stretched, and when the inner top wall of the tilting block 12... When the top arc of the locking block 17 is touched, the locking block 17 is squeezed. Then the locking block 17 drives the guide rod 16 to move downward, which compresses the compression spring 15. The locking block 17 then descends. At this time, the worker continues to push the tilting block 12 to the left until the slot inside the tilting block 12 moves to the position above the locking block 17. At this time, the compression spring 15 returns to its original position. Then the connecting block and the guide rod 16 return to their original positions, so that the locking block 17 touches upward and is locked into the slot. At this time, the tilting block 12 is locked. At this time, the contact cover 3 is tightly attached to one side of the hydrogen cylinder 4 to keep it fixed. The steel wire rope 8 is also in a taut state to further ensure the stability of the hydrogen cylinder 4.
