A kind of high-pressure hydrogen storage tank special layer board wrapping machine and layer board wrapping system

Abstract

This invention discloses a special layer wrapping machine and layer wrapping system for high-pressure hydrogen storage tanks, including a ground rail, a sliding platform mounted on the ground rail, a column rotatably mounted on the sliding platform, a lifting plate sliding on the column, a connecting beam fixed at the end of the lifting plate away from the column, and a load-bearing beam fixed at the end of the connecting beam away from the lifting plate. The load-bearing beam is equipped with multiple clamping mechanisms and multiple binding mechanisms. The wrapping machine uses the binding mechanisms to wrap steel plates around the outside of the hydrogen storage tank, then uses the clamping mechanisms to clamp the joints of the steel plates, and finally welds the joints. During the movement of the welding torch, the wrapping system controls the binding mechanisms to make way, without increasing the burden on the clamping mechanisms. While maintaining the binding effect, the welding torch can work continuously and completely without the need for re-welding at the binding position, resulting in a high degree of weld flatness that does not affect the fit of the next layer of steel plate.

Description

Technical Field

[0001] This invention belongs to the field of hydrogen storage tank wrapping technology, specifically relating to a special layer wrapping machine and layer wrapping system for high-pressure hydrogen storage tanks. Background Technology

[0002] Hydrogen storage tanks are a general term for constant-pressure variable-volume (wet gas holders) and variable-pressure constant-volume containers used to store hydrogen. Hydrogen storage tanks require high strength. Wrapping the tank with steel plates effectively increases strength and is cost-effective. However, current technology struggles to achieve multi-layer steel plate wrapping for hydrogen storage tanks. The main problems are: excessively thick steel plates are difficult to bend, while thin plates lack strength and are easily welded through; sufficient pre-tightening force is required when bending the steel plates for welding to prevent joint movement from affecting the welding effect; and the flatness of the weld affects the adhesion of the next layer of steel plate.

[0043] Example 2

[0044] Unlike Embodiment 1 described above, this embodiment also includes a fixing frame 53, which is fixedly connected to the load-bearing beam 21 via a fixing member 56. A fixing rod 58 is fixedly mounted on one side of the fixing frame 53, and a welding torch 55 is slidably mounted on the fixing rod 58. A row of alignment holes 71 are fixedly mounted on both sides of the steel plate 26 near its splice joint, and the alignment holes 71 cooperate with the clamping column 46.

[0046] Advantageously, a fixed rack 59 is fixedly provided on the side of the fixed rod 58 away from the fixed frame 53, and a moving gear 60 is provided on the side of the fixed rack 59 away from the fixed rod 58.

[0047] Example 3

[0048] Unlike Embodiment 2 described above, the mounting plate 47 is fixedly connected to the load-bearing beam 21. The load-bearing beam 21 has a mounting space. A control motor 65 is located on one side of the mounting plate 47 within this mounting space. The control motor 65 is fixedly connected to the load-bearing beam 21, and a control gear 69 is fixedly mounted on the output shaft of the control motor 65. The mounting plate 47 has two sliding grooves 68, located on either side of the control motor 65. Two load-bearing blocks 48 are positioned close to one side of the load-bearing beam 21. A control block 66 is fixedly provided on each side, and the two control blocks 66 are slidably connected to the two slide grooves 68 respectively. A control rack 67 is fixedly provided on the side of each control block 66 near the control motor 65, and the two control racks 67 are respectively meshed with the control gear 69. An extension block 70 is fixedly provided at the end of the drive rod 51 away from the binding cylinder 50. The extension block 70 is located between the drive rod 51 and the binding rod 49, and the drive rod 51 is hinged to the binding rod 49 through the extension block 70. By adding a clearance function to the binding mechanism 22, the control motor 65 is activated by a sensor after the welding torch reaches the binding mechanism. This allows the welding torch 55 to work continuously without being affected by the binding mechanism 22, producing a continuous and complete weld, resulting in higher welding strength, and without affecting the welding of the next layer of steel plate 26. When the binding mechanism 22 is not completely removed, the workload of the adjacent clamping mechanism 28 can be reduced, the service life of the clamping mechanism 28 can be increased, and the joint of the steel plate 26 is less likely to loosen during the welding process.

[0049] Working principle of this invention:

[0050] A special layer-wrapping machine for high-pressure hydrogen storage tanks includes a moving platform 12 whose movement relative to the ground rail 11 is driven by a motor and controlled by a control cabinet 34. The control cabinet 34 can also control a steering motor 73 and a lifting motor 16. The steering motor 73 enables the synchronous rotation of the column 15, connecting beam 20, load-bearing beam 21, and operating room 35. The lifting motor 16 drives the lifting plate 14 to rise and fall via a chain 19. The rising and falling of the lifting plate 14 causes the connecting beam 20 and load-bearing beam 21 to move synchronously. The binding mechanism 22 and the clamping mechanism 28 move together with the load-bearing beam 21.

[0051] The operator enters the operating room 35 and slides the extension plate 36 to provide more operating space for the operator. The operator can move the clamping mechanism 28 by grasping the operating handle 41.

[0052] A special layered wrapping system for high-pressure hydrogen storage tanks involves hoisting or transferring the hydrogen storage tank 23 onto four support wheels 31 before the load-bearing beam 21 is positioned above the platform 25. A steel plate 26 is bent and placed under the hydrogen storage tank 23, and then a binding rope 30 is installed to bind the steel plate 26 and the hydrogen storage tank 23. The binding cylinder 50 is activated, and after the piston rod of the binding cylinder 50 extends, it drives two binding rods 49 to rotate via the drive rod 51. The binding rods 49 rotate around the load-bearing block 48, causing the two connecting hooks 52 to move away from each other until the binding rope 30 tightens to form a circle that is tightly attached to the steel plate 26.

[0053] The operator holds the operating handle 41, aligns the clamping column 46 with the alignment hole 71, and starts the clamping cylinder 43. The piston rod of the clamping cylinder 43 extends, and the two clamping columns 46 corresponding to the same clamping mechanism 28 move closer to each other, so that the splice seam of the steel plate 26 is closed.

[0054] Then, the splice seams of the steel plates 26 are welded. After the welding of one layer of steel plates 26 is completed, the clamping mechanism 28 is removed, and the binding rope 30 on one side of the binding mechanism 22 is removed. The rotating motor 24 is started, and the rotating motor 24 controls the support wheel 31 to rotate. The support wheel 31 drives the hydrogen storage tank 23 to rotate, so that the splice seams of the upper layer of steel plates 26 are rotated to other positions, and then the next layer of steel plates 26 is wrapped.

[0055] The welding process of the steel plate 26 is completed by the welding torch 55. The welding motor 64 drives the drive gear 57 to rotate. The drive gear 57 drives the transmission gear 72 to rotate through meshing. The transmission gear 72 drives the rotating shaft 61 to rotate. The moving gear 60 rotates together with the rotating shaft 61. Under the meshing action of the rotating shaft 61 and the fixed rack 59, the rotating shaft 61 moves along the fixed rack 59, thereby driving the mounting part 63, the extension rod 54 and the welding torch 55 to move together. During this period, the welding torch 55 and the extension rod 54 can pass through the gap between the clamping mechanism 28 and the splice of the steel plate 26, that is, the gap between the first clamp 42 and the second clamp 44 of the same clamping mechanism 28.

[0056] When the welding torch 55 passes the binding rope 30, the control motor 65 is started, and the control motor 65 drives the control gear 69 to rotate. The control gear 69 drives the two control racks 67 to move through meshing. The two control blocks 66 slide along the two slide grooves 68 respectively, and the two load-bearing blocks 48 move together with the two control blocks 66. The two load-bearing blocks 48 move closer to each other, and at the same time, the control piston rod of the binding cylinder 50 retracts, so the horizontal height of the two connecting hooks 52 will rise, and the distance between the two connecting hooks 52 will slightly decrease. However, the binding rope 30 will still be taut. The intersection of the binding rope 30 above the weld of the steel plate 26 will move away from the weld. The included angle formed by the two ends of the binding rope 30, of which the included angle at the top will decrease during the above process. At this time, the welding torch 55 and the extension rod 54 can pass smoothly through the gap between the intersection of the binding rope 30 and the weld.

[0057] Referring to the attached diagrams of the moving platform 12 and the lifting plate 14, the lifting plate 14 is a schematic diagram showing the movement of the two slides 68 of the moving platform 12, but the piston rod of the binding cylinder 50 remains unchanged. By comparison, it can be seen that the horizontal height of the two connecting hooks 52 increases, but the distance between the two connecting hooks 52 also increases. After the binding rope 30 tightly wraps the steel plate 26, there is no extra length for the two connecting hooks 52 to move further apart. Therefore, the binding cylinder 50 is started simultaneously. If the piston rod of the binding cylinder 50 is retracted based on the lifting plate 14, the distance between the two connecting hooks 52 can be reduced. Therefore, when the control motor 65 and the binding cylinder 50 are started simultaneously, the connecting hooks 52 can move along the ideal path without breaking the binding rope 30.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.

A control rack is fixedly mounted on the side of each control block closest to the control motor, and the two control racks mesh with the control gears. An extension block is fixedly mounted on the end of the drive rod furthest from the strapping cylinder. The extension block is located between the drive rod and the strapping rod, and the drive rod is hinged to the strapping rod via the extension block. When the welding torch passes the binding rope, the control motor is activated, driving the control gear to rotate. The control gear meshes with the two control racks, causing the two control blocks to slide along the two grooves respectively. The two load-bearing blocks move together with the two control blocks. The two load-bearing blocks move closer to each other, and at the same time, the piston rod of the binding cylinder retracts, raising the horizontal height of the two connecting hooks. Simultaneously, the distance between the two connecting hooks decreases, and the binding rope becomes taut. The intersection of the binding rope above the weld seam of the steel plate moves away from the weld seam. The welding torch and extension rod pass through the gap between the intersection of the binding rope and the weld seam. The welding torch works continuously, producing a continuous and complete weld seam.
