Description

Technical Field

[0001] This invention belongs to the field of hydrogen storage tank wrapping technology, specifically relating to a multi-layer wrapping type steel plate end alignment device for hydrogen storage tanks. Background Technology

[0002] Wrapping the outside of the hydrogen storage tank with steel plates can effectively improve its strength. The cost of using steel plate wrapping to improve strength is much lower than directly casting a thick hydrogen storage tank. However, existing wrapping technologies have problems such as the steel plates being too thick to bend and weld. If thinner steel plates are selected, multiple layers need to be wrapped. During the wrapping process, the ends of the steel plates are not easy to align, often requiring later cutting and welding. If the steel plates are moved before they are fully welded, the hydrogen storage tank or the upper layer of steel plate may be scratched, or even the weld of the upper layer of steel plate may be broken.

With the help of the photoelectric sensor, after the steel plate is initially formed, the steel plate is finely adjusted along the axis of the hydrogen storage tank, so that the ends of the multi-layer steel plates can be aligned, improving the wrapping effect and reducing post-processing.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments.

[0024] The following is combined with Figure 1-5 The following describes a specific embodiment of the present invention: a multi-layer wrapped hydrogen storage tank steel plate end alignment device, comprising two supports 17, each support 17 having two mounting brackets 24 fixedly mounted on one side, each mounting bracket 24 having a rotatable roller 23 rotatably mounted on it, a mounting beam 25 mounted on the side of each support 17 away from the mounting brackets 24, the two ends of the mounting beam 25 being fixedly connected to the two supports 17 respectively, an alignment motor 34 fixedly mounted on the side of the mounting beam 25 away from the supports 17, the output shaft of the alignment motor 34 passing through the alignment motor 34, a first threaded rod 35 fixedly mounted on each end of the output shaft of the alignment motor 34, an alignment groove 14 fixedly mounted on the side of each of the two supports 17 away from each other, a moving rod 13 slidingly mounted in each alignment groove 14, a first threaded block 32 fixedly mounted on each moving rod 13, the two first threaded blocks 32 being threadedly engaged with the two first threaded rods 35 respectively; a bushing 12 fixedly mounted on the side of each moving rod 13 away from the first threaded block 32. As the steel plates 29 are wrapped layer by layer, the thickness of the hydrogen storage tank 28 gradually increases. The thickness of the bushing 12, after it is fitted with the steel plates 29 and the hydrogen storage tank 28, creates a gap between the steel plates 29 and the hydrogen storage tank 28. This gap is larger than the outermost steel plate 29, that is, the last layer of steel plate 29 wrapped. The outermost steel plate 29 will not be scratched during the wrapping process, so it is also impossible for it to be scratched when wrapping the inner steel plates 29.

[0025] Advantageously, a rotating motor 18 is fixedly mounted on one side of one of the supports 17, and the output shaft of the rotating motor 18 drives one of the towing wheels 23; a hydrogen storage tank 28 is placed on the side of the support 17 where the towing wheel 23 is located, and the hydrogen storage tank 28 is located between the two towing wheels 23 on the same side. The towing wheel 23 directly contacts the surfaces at both ends of the hydrogen storage tank 28, and this contact part is not covered by the steel plate 29, that is, the steel plate 29 only covers the middle part of the hydrogen storage tank 28.

[0026] Advantageously, a lifting cylinder 40 is provided on the side of the mounting beam 25 away from the positioning motor 34. The cylinder barrel of the lifting cylinder 40 is fixedly connected to the mounting beam 25. A fixing plate 36 is fixedly provided on the piston rod of the lifting cylinder 40. A movable plate 37 is provided on the side of the fixing plate 36 away from the lifting cylinder 40. The fixing plate 36 and the movable plate 37 are slidably connected. Two connecting seats 39 are fixedly provided on the side of the movable plate 37 away from the fixing plate 36. An arc-shaped clamp 16 is rotatably provided on each connecting seat 39.

The second threaded block 30 is threadedly engaged with the second threaded rod 31. The control motor 33 enables the fixed plate 36 and the moving plate 37 to be precisely adjusted in position. With the help of photoelectric sensors, after the steel plate 29 is initially formed, the steel plate 29 is finely adjusted along the axis of the hydrogen storage tank 28, so that the ends of the multi-layer steel plate 29 can be aligned, improving the wrapping effect and reducing post-processing.

[0028] Advantageously, a forming cylinder 27 is provided on each side of the two arc-shaped clamps 16 that are far apart from each other. The cylinder barrels of the two forming cylinders 27 are respectively hinged to the moving plate 37, and the piston rods of the two forming cylinders 27 are respectively hinged to the two arc-shaped clamps 16.

[0029] Advantageously, the bushing 12 includes a rotating ring 46, which is fixedly connected to the moving rod 13. A plurality of connecting ribs 45 are fixedly provided on the side of the rotating ring 46 away from the moving rod 13, and a support ring 44 is fixedly provided on the side of the connecting ribs 45 away from the rotating ring 46. A plurality of rotating beads 42 are provided around the periphery of the support ring 44. The connecting ribs 45 reduce the weight of the bushing 12, and the internal structure of the bushing 12 can be viewed through the connecting ribs 45.

[0030] Advantageously, the rotating beads 42 are rotatably connected to the support ring 44, and a plurality of the rotating beads 42 are evenly distributed along the circumference of the support ring 44; the support ring 44 is provided with two reserved grooves 43, and the two reserved grooves 43 correspond to the two drag wheels 23 on the same side respectively. The rotating beads 42 are rolling balls clamped on the surface of the support ring 44, which can further reduce the friction between the steel plate 29 and the bushing 12, and facilitate the removal of the bushing 12 after the steel plate is initially formed.

[0031] Advantageously, it also includes a load-bearing beam 11, on the side of the load-bearing beam 11 near the support 17, a plurality of control cylinders 21 are fixedly provided, the cylinder barrels of the plurality of control cylinders 21 are respectively fixedly connected to the load-bearing beam 11, and two transmission rods 22 are rotatably provided on the piston rod of each control cylinder 21, and a control rod 20 is provided on one side of each transmission rod 22; one end of the control rod 20 is hinged to the load-bearing beam 11, and the other end of the control rod 20 is provided with a steel cable 19, and the control rod 20 is hinged to the transmission rod 22.

[0032] Advantageously, the supporting beam 11 is provided with a plurality of suspension ropes 49 on the side near the support 17, and each suspension rope 49 is provided with a clamping mechanism. The clamping mechanism includes two clamping members 47, which are hinged to each other and connected to the suspension ropes 49 respectively. A clamping cylinder 48 is provided between the two clamping members 47. The cylinder and piston rod of the clamping cylinder 48 are hinged to the two clamping members 47 respectively. A clamping post 26 is fixedly provided at the end of each clamping member 47 away from the suspension ropes 49.

[0033] Advantageously, the hydrogen storage tank 28 is provided with a steel plate 29 on its periphery, and a weld is formed at the splice of the steel plate 29. The weld is close to the supporting beam 11, and a row of alignment holes is provided on both sides of the weld. The alignment holes cooperate with the clamping column 26.

[0034] Working principle of this invention:

[0035] In the initial state, the piston rod of the lifting cylinder 40 retracts, and the fixed plate 36 contacts the support plate 38; the piston rod of the forming cylinder 27 retracts; the two bushings 12 move away from each other, and the hydrogen storage tank 28 is placed on the towing wheel 23;

[0036] Start the alignment motor 34 and control the rotation of the first threaded rods 35 on both sides. With the cooperation of the first threaded block 32, the two first threaded blocks 32 move closer to each other, which drives the two moving rods 13 and bushings 12 to move closer to each other. The two bushings 12 are inserted into both ends of the hydrogen storage tank 28 until the two rotating rings 46 are in close contact with the ends of the hydrogen storage tank 28. At this time, the hydrogen storage tank 28 is fixed on the support 17 and is located in the center position.

[0037] Place the flat steel plate 29 between the arc-shaped clamp 16 and the hydrogen storage tank 28, start the lifting cylinder 40, the piston rod of the lifting cylinder 40 extends, control the fixed plate 36 and the moving plate 37 to rise, the connecting seat 39 and the arc-shaped clamp 16 rise at the same time, the middle position of the steel plate 29 touches the hydrogen storage tank 28, the arc-shaped clamp 16, and the two sides of the steel plate 29 are initially bent.

[0038] The forming cylinder 27 is started, the piston rod of the forming cylinder 27 extends, and the arc clamp 16 is controlled to flip. The two arc clamps 16 bend the steel plate 29 until the steel plate 29 is fastened to the periphery of the hydrogen storage tank 28.

[0039] During the bending process described above, the two sides of the steel plate 29 will come into contact with the periphery of the bushing 12. Therefore, during the bending process, the steel plate 29 will not come into contact with the surface of the hydrogen storage tank 28.

[0040] After the steel plate 29 is initially formed, the control motor 33 is started. The control motor 33 controls the second threaded rod 31 to rotate. The second threaded rod 31 cooperates with the second threaded block 30, thereby driving the second threaded block 30 and the moving plate 37 to move. The moving plate 37 slides relative to the fixed plate 36. Since the steel plate 29 is only initially formed, the steel plate 29 has a tendency to return to its original shape. It can only maintain its cylindrical shape under the clamping action of the two arc-shaped clamps 16. The steel plate 29 and the clamping column 26 squeeze each other, and there is a large friction between them. Therefore, when the arc-shaped clamps 16 move, they can easily drive the steel plate 29 to move together.

[0041] During the movement of the steel plate 29, it undergoes rolling friction with the rotating ball 42 on the bushing 12, which will not scratch the hydrogen storage tank 28, nor will it scratch the steel plate 29; thus achieving zero wear when the steel cable 19 moves relative to the hydrogen storage tank 28.

[0042] The position of the steel plate 29 is detected by a photoelectric sensor, and the steel plate 29 is moved to the ideal position.

[0043] The steel plate 29 is tied with steel cable 19, and the two bushings 12 are controlled to move away from each other. At this time, the control cylinder 21 is activated to control its piston rod to extend. Through the transmission rod 22, the control rods 20 on both sides can be moved away from each other, thereby tightening the steel cable 19 and making the steel plate 29 completely close to the hydrogen storage tank 28. The clamping mechanism is moved to the upper side of the weld, so that the clamping column 26 is inserted into the alignment hole. The clamping cylinder 48 is activated to bring the two clamping columns 26 of the clamping mechanism closer to each other and clamp the weld of the steel plate 29.

[0044] The joints of steel plates 29 are welded together using welding equipment.

[0045] After the first layer of steel plate 29 is welded, the entire equipment is reset, the rotating motor 18 is started, and the towing wheel 23 is controlled to rotate. The towing wheel 23 drives the hydrogen storage tank 28 to rotate, moving the previous weld to another position. Then the next layer of steel plate 29 is wrapped. The wrapping of subsequent layers of steel plates 29 is the same as the first layer. When placing the steel plates 29, precise placement is not required. After bending and initial shaping, the position of the steel plates 29 is adjusted using photoelectric sensors to align the ends of the multiple layers of steel plates 29.

[0046] Specifically, when the bushing 12 moves relative to the hydrogen storage tank 28, the reserved groove 43 will contact the hydrogen storage tank 28 through the position of the towing wheel 23, without interfering with the normal contact between the towing wheel 23 and the hydrogen storage tank 28, and without interfering with the towing wheel 23 driving the hydrogen storage tank 28 to rotate.

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.
