This results in the storage tank failing to achieve the desired sealing performance, posing significant safety hazards. Therefore, this invention proposes a welding device for large yellow phosphorus storage tanks with high sealing performance. Utility Model Content

[0033] Example

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention proposes a welding device for a large, highly airtight yellow phosphorus storage tank, comprising at least one set of movable plates 1, a welding gun 3 mounted above the movable plates 1, and multiple sets of movable wheels 11 installed at the bottom of the movable plates 1, the movable wheels 11 being driven by a motor. During welding, the bottom plate of the storage tank is located on the boss, and the aforementioned welding device is located on the outer ring of the boss.

[0035] For further details, please refer to Figure 2 and Figure 3, the above-mentioned welding device further includes a guiding mechanism 2 disposed on the side of the moving plate 1 close to the storage tank. The guiding mechanism 2 is used to guide the moving plate 1. The guiding mechanism 2 includes a synchronous plate 21 fixedly connected to the side of the moving plate 1, and the synchronous plate 21 moves synchronously with the moving plate 1. Above the synchronous plate 21, there is an upper clamping plate 22, which is L-shaped. A plurality of groups of bolts 23 are arranged through the upper clamping plate 22. The plurality of groups of bolts 23 penetrate through the upper clamping plate 22 and the synchronous plate 21 and are threadedly connected with threaded sleeves 24. The sides of the plurality of threaded sleeves 24 away from the moving plate 1 are fixedly connected together with a lower clamping plate 25, and the lower clamping plate 25 is U-shaped. After tightening the bolts 23, the upper clamping plate 22 and the lower clamping plate 25 are fixed to both sides of the synchronous plate 21. A guiding ring 26 is arranged between the upper clamping plate 22 and the lower clamping plate 25. The upper clamping plate 22 and the lower clamping plate 25 are slidably connected to both sides of the guiding ring 26. When the guiding ring 26 is fixed, the moving plate 1 makes a circular motion through the guiding action of the upper clamping plate 22 and the lower clamping plate 25. A plurality of groups of support plates 27 are fixedly connected to the inner side of the guiding ring 26. The support plates 27 are L-shaped. The support plates 27 are slidably connected between the upper clamping plate 22 and the lower clamping plate 25. The position of the guiding ring 26 is fixed through the arrangement of the support plates 27, and at the same time, the support plates 27 do not prevent the movement of the upper clamping plate 22 and the lower clamping plate 25.

[0036] Furthermore, the above-mentioned welding device further includes a position adjustment component 4 installed on the top of the moving plate 1. The position adjustment component 4 is used to drive the welding gun 3 to move to complete the welding operation. The position adjustment component 4 includes two groups of slide rails 41 fixedly connected to the top of the moving plate 1. A plurality of groups of sliders 42 are slidably connected to the slide rails 41. A first mounting frame 43 is fixedly connected to the plurality of groups of sliders 42. The first mounting frame 43 is C-shaped. The welding gun 3 is installed on the top of the first mounting frame 43. Through the arrangement of the slide rails 41 and the sliders 42, the movement of the first mounting frame 43 is limited when it moves, so that the movement of the welding gun 3 is stable. A push rod motor 44 is installed on the top of the moving plate 1. The output end of the push rod motor 44 is fixedly connected to a connecting plate 45. The connecting plate 45 is connected to the bottom of the first mounting frame 43. After the first mounting frame 43 is started, it drives the first mounting frame 43 to move through the connecting plate 45, and then drives the welding gun 3 to move, which is convenient to move the welding gun 3 to make it close to the joint of the bottom plate and the side wall of the storage tank to complete the welding operation.

[0037] Specifically, the welding device also includes a distance sensing mechanism 5 disposed on the side of the welding gun 3. The distance sensing mechanism 5 is used to monitor the distance between the welding gun 3 and the storage tank. The distance sensing mechanism 5 includes a second mounting frame 51 mounted on the top of the first mounting frame 43. Multiple sets of fixing plates 52 are fixedly connected to the top of the second mounting frame 51. By setting the second mounting frame 51, the fixing plates 52 move synchronously with the first mounting frame 43, thereby the fixing plates 52 and the welding gun 3 move synchronously. Multiple sets of sliding rods 53 are slidably connected in the fixing plates 52. The ends of the multiple sets of sliding rods 53 in the same set of fixing plates 52 near the storage tank are fixedly connected to a mounting base 54. Rollers 55 are rotatably connected in the mounting base 54. The rollers 55 contact the side wall of the storage tank. When the moving plate 1 moves, the rollers 55 roll on the side wall of the storage tank to reduce friction. A spring 56 is sleeved on the outer ring of the sliding rod 53. The spring 56 is disposed between the fixing plate 52 and the mounting base 54. The spring 56 is used to release the elastic force so that the rollers 55 move closer to the side wall of the storage tank. One end of the slide rod 53 away from the mounting base 54 is fixedly connected to a limiting plate 57, which prevents the slide rod 53 from detaching from the fixing plate 52. Multiple sets of slide rods 53 in the same group of fixing plates 52 are slidably connected to pressure plates 58. A pressure sensor 59 is installed on the side of the pressure plate 58 near the fixing plate 52. After the pressure plate 58 contacts the side wall of the storage tank, the push rod motor 44 drives the second mounting frame 51 and the fixing plate 52 to move continuously, causing the slide rod 53 to slide within the fixing plate 52, while the spring 56 is compressed. The pressure plate 58, in conjunction with the pressure sensor 59, senses the force of the spring 56. A greater force indicates that the welding gun 3 is closer to the storage tank joint, while a smaller force indicates that the welding gun 3 is further away from the storage tank joint. Therefore, the optimal welding position for the welding gun 3 can be determined based on the force of the spring 56.

[0038] Furthermore, the aforementioned welding device also includes a control module, and the welding gun 3, push rod motor 44, pressure sensor 59, and the motor driving the moving wheel 11 are all electrically connected to the control module.

[0039] In this embodiment, firstly, the bottom plate of the storage tank is placed on the boss, and the side wall of the storage tank is pre-fixed. By tightening the bolts 23, the upper clamping plate 22 and the lower clamping plate 25 clamp the synchronization plate 21, thereby establishing a connection between the moving plate 1 and the guide ring 26. Multiple moving plates 1, along with the welding gun 3, position adjustment assembly 4, and distance sensing mechanism 5 on them, can be set to realize segmented welding operations. The motor driving the moving wheel 11 is started, and under the guidance of the guide mechanism 2, the moving plate 1 slides along the guide ring 26 with the upper clamping plate 22 and the lower clamping plate 25, making a circular motion around the bottom edge of the storage tank, thus completing the overall movement and positioning of the welding device.

[0040] Then, the push rod motor 44 is started. Its output end drives the first mounting frame 43 to slide along the slide rail 41 through the connecting plate 45, thereby moving the welding gun 3 mounted on the top of the first mounting frame 43, so that the welding gun 3 gradually approaches the joint between the bottom plate and the side wall of the storage tank. As the moving plate 1 and the welding gun 3 move, the roller 55 contacts and rolls with the side wall of the storage tank, reducing the friction during the movement. When the pressure plate 58 contacts the side wall of the storage tank, the push rod motor 44 continues to drive the second mounting frame 51 and the fixed plate 52 to move. The slide rod 53 slides in the fixed plate 52, and the spring 56 is compressed. The pressure sensor 59 senses the magnitude of the spring force 56 transmitted by the pressure plate 58 in real time and transmits the signal to the control module. The control module determines whether the welding gun 3 is in the appropriate position according to the preset correspondence between the spring force 56 and the optimal welding position of the welding gun 3. When the spring force 56 reaches the set value, it indicates that the welding gun 3 is in the optimal welding position, and the control module controls the push rod motor 44 to stop operating.

[0041] Finally, the control module starts the welding gun 3 to begin the welding operation. As the moving plate 1 moves continuously in a circle along the guide ring 26, the welding gun 3 continuously welds the seam at the bottom edge of the storage tank until the welding work of the entire bottom edge of the storage tank is completed.

[0042] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
