[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] like Figures 1 to 6 As shown, this utility model embodiment provides a cylinder assembly fixture for a vertical hydrogen system, including: a base 1, a support plate 2, a lifting assembly 3, and a fixing assembly 4.

[0033] The two ends of the lifting assembly 3 are connected to the base 1 and the support plate 2, respectively.

[0034] The fixing component 4 includes two fixing rods 41, multiple triangular limiting brackets 42, rollers 43 and connecting plates 44. The two fixing rods 41 are respectively disposed on both sides of the support plate 2. The rollers 43 are evenly spaced on the inner wall of the fixing rods 41 and abut against the gas cylinder 110. The connecting plates 44 are respectively disposed on the top of the two fixing rods 41. The multiple triangular limiting brackets 42 are respectively connected to the connecting plates 44, and each fixing rod 41 has at least two triangular limiting brackets 42.

[0035] Specifically, the distance between the two fixing rods 41 is less than the diameter of the gas cylinder 110 and greater than half the diameter of the gas cylinder 110.

[0036] like Figure 1 As shown, during use, the operator places the gas cylinder 110 on the support plate 2. The rollers 43 provide support for the gas cylinder, and the triangular limit bracket 42 restricts the gas cylinder 100 to prevent it from slipping off 110, thus ensuring that the gas cylinder 110 is stably placed on the support plate 2. Next, the gas cylinder 110 assembly fixture is moved to the vertical hydrogen system 120, and the support plate 2 is raised or lowered by the lifting component 3, so that the gas cylinder 110 on the support plate 2 corresponds to the cavity in the vertical hydrogen system. The rollers 43 enable the gas cylinder 110 to be quickly and stably pushed into the vertical hydrogen system.

[0037] This utility model connects the two ends of the lifting assembly 3 to the base 1 and the support plate 2 respectively, and sets two fixed rods 41 on both sides of the support plate 2 respectively. Rollers 43 are evenly spaced on the inner wall of the fixed rods 41 and abut against the gas cylinder 110. Connecting plates 44 are set on the top of the two fixed rods 41 respectively. Multiple triangular limit frames 42 are connected to the connecting plates 44 respectively, and each fixed rod 41 has at least two triangular limit frames 42. In use, the operator places the gas cylinder 110 on the support plate 2. The rollers 43 provide support for the gas cylinder, and the triangular limit bracket 42 restricts the gas cylinder 110 to prevent it from slipping off, thus ensuring that the gas cylinder 110 is stably placed on the support plate 2. Next, the gas cylinder 110 assembly fixture is moved to the vertical hydrogen system 120. The lifting component 3 drives the support plate 2 to rise or fall, thereby aligning the gas cylinder 110 on the support plate 2 with the cavity in the vertical hydrogen system. The rollers 43 enable the gas cylinder 110 to be quickly and stably pushed into the vertical hydrogen system, reducing the operator's labor intensity, effectively improving work efficiency, and also reducing safety hazards.

[0038] In one embodiment of the gas cylinder assembly fixture for a vertical hydrogen system of this utility model, such as Figure 1 and Figure 4 As shown, a buffer pad 5 is provided on the triangular limit frame 42. This arrangement provides protection for the gas cylinder 110 and the triangular limit frame 42, avoiding the problem of damage caused by collision between the gas cylinder 110 and the triangular limit frame 42.

[0039] In one embodiment of the gas cylinder assembly fixture for a vertical hydrogen system of this utility model, such as Figure 4 As shown, the fixing component 4 also includes a first oblong hole 421, a mounting hole and a first fastening bolt. The first oblong hole 421 is located on the bottom edge of the triangular limiting frame 42, the mounting holes are evenly spaced on the connecting plate 44, and the first fastening bolt passes through the first oblong hole 421 and the mounting hole.

[0040] This utility model improves stability by setting the first waist-shaped hole 421 on the bottom edge of the triangular limiting frame 42 and evenly spaced the mounting holes on the connecting plate 44, and passing the first fastening bolt through the first waist-shaped hole 421 and the mounting hole.

[0041] Furthermore, the position of the first fastening bolt in the first waist-shaped hole 421 and the mounting hole can be adjusted according to the size of the gas cylinder 110, thereby changing the position of the triangular limit bracket 42 on the connecting plate 44, so that the distance between the two oppositely arranged triangular limit brackets 42 can be increased or decreased, so that gas cylinders 110 of different sizes can be placed between the two oppositely arranged triangular limit brackets 42.

[0042] In one embodiment of the gas cylinder assembly fixture for a vertical hydrogen system of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the fixing assembly 4 also includes two first connecting rods 45 and a plurality of second connecting rods 46 disposed on the support plate 2. The first connecting rods 45 are respectively located outside the two fixing rods 41 and are horizontally disposed with the fixing rods 41. The two ends of the second connecting rods 46 are respectively connected to the two first connecting rods 45. The plurality of second connecting rods 46 are evenly spaced along the length direction of the first connecting rods 45. The bottom of the fixing rods 41 is connected to the second connecting rods 46.

[0043] This utility model connects the two ends of the second connecting rod 46 to two first connecting rods 45 respectively, and the multiple second connecting rods 46 are evenly spaced along the length direction of the first connecting rods 45. The bottom of the fixing rod 41 is connected to the second connecting rods 46. Through the first connecting rods 45 and the second connecting rods 46, the stability of the fixing rod 41 is further increased, thereby further ensuring the safety of the transportation and assembly of the gas cylinder 110.

[0044] In one embodiment of the gas cylinder assembly fixture for a vertical hydrogen system of this utility model, such as Figure 2 and Figure 4 As shown, the fixing component 4 also includes a first fixing plate 47, a second oblong hole 48, a first fixing hole, and a second fastening bolt. The first fixing plate 47 is disposed on the outside of the two fixing rods 41. The second oblong hole 48 is disposed on the first fixing plate 41. The first fixing holes are evenly spaced at both ends of the second connecting rod 46. The second fastening bolt passes through the second oblong hole 48 and the first fixing hole respectively.

[0045] Specifically, when the gas cylinder 110 is too large or too small, and simply adjusting the position of the triangular limiting bracket 42 is insufficient to fix the gas cylinder 110, the operator can also adjust the position of the second fastening bolt in the second oblong hole 48 and the first fixing hole, thereby adjusting the position of the two fixing rods 41. This increases or decreases the distance between the two fixing rods 41, and increases or decreases the distance between the two opposing triangular limiting brackets 42. Furthermore, the two opposing triangular limiting brackets 42 can fix gas cylinders 110 of different sizes, improving the convenience of assembly.

[0046] In one embodiment of the gas cylinder assembly fixture for a vertical hydrogen system of this utility model, such as Figure 2 , Figure 3 and Figure 5 As shown, the cylinder assembly fixture for the vertical hydrogen system also includes a limiting sleeve 6, a third connecting rod 7, and a retaining ring 8. The limiting sleeve 6 is respectively set on the second connecting rod 46 at both ends of the first connecting rod 45. The first end of the third connecting rod 7 is connected to the retaining ring 8, and the second end of the third connecting rod 7 is inserted into the limiting sleeve 6. The diameter of the retaining ring 8 is smaller than the diameter of the cylinder 110.

[0047] This utility model sets the limiting sleeves 6 on the second connecting rods 46 at both ends of the first connecting rod 45, and connects the first end of the third connecting rod 7 to the retaining ring 8. The second end of the third connecting rod 7 is inserted into the limiting sleeve 6. Thus, the retaining rings 8 located at both ends of the gas cylinder 110 can provide a limiting function for the gas cylinder 110, avoiding the problem of it falling off the support plate 2 during the lifting process or the movement of the cylinder assembly tooling.

[0048] Furthermore, when it is necessary to push the gas cylinder 110 into the vertical hydrogen system 120, the operator can pull the third connecting rod 7 out of the limiting sleeve 6 to release the limiting of the gas cylinder 110. The structure is simple and easy to use.

[0049] In one embodiment of the gas cylinder assembly fixture for a vertical hydrogen system of this utility model, such as Figure 3 and Figure 6 As shown, the cylinder assembly fixture for the vertical hydrogen system also includes casters 9, which are located at the four corners of the base 1. This arrangement allows the operator to move the cylinder 110 assembly fixture, improving ease of use.

[0050] In one embodiment of the gas cylinder assembly fixture for a vertical hydrogen system of this utility model, such as Figure 6As shown, the cylinder assembly fixture for the vertical hydrogen system also includes a limiting component 10. The limiting component 10 includes a limiting plate 101, a driving cylinder, a fixing sleeve 102, and a fixing block 103. The first end of the limiting plate 101 is connected to the bracket of the universal wheel 9. The fixing sleeve 102 is located at the second end of the limiting plate 101. The driving cylinder is located inside the fixing sleeve 102, and the output shaft of the driving cylinder is connected to the fixing block 103.

[0051] Specifically, when the operator moves the gas cylinder 110 assembly fixture to correspond with the vertical hydrogen system 120, the operator starts the drive cylinder, which drives the fixing block 103 to move downward, thereby enabling multiple fixing blocks 103 to support the base 1, thus preventing the gas cylinder 110 assembly fixture from moving during the installation of the gas cylinder 110 and improving safety.

[0052] In one embodiment of the gas cylinder assembly fixture for a vertical hydrogen system of this utility model, such as Figure 2 and Figure 3 As shown, the lifting assembly 3 includes a second fixed plate 31, a scissor lift boom 32, and a hydraulic cylinder. The second fixed plate 31 is respectively disposed at the bottom of the support plate 2 and the top of the base 1, and both ends of the scissor lift boom 32 are respectively connected to the second fixed plate 31. The hydraulic cylinder is connected to the bottom of the scissor lift boom 32 and is used to drive the support plate 2 to lift.

[0053] This utility model connects the two ends of the scissor lift boom 32 to the second fixed plate 31 respectively, and connects the hydraulic cylinder to the bottom of the scissor lift boom 32. In use, the operator starts the hydraulic cylinder, which drives the scissor lift boom 32 to raise or lower the support plate 2, thereby facilitating the installation of the gas cylinder 110.
