[0015] This invention proposes a welding device for a plate-type surface tension storage tank. Existing tank welding devices lack sufficient protection for workers and the environment during the welding process. This invention, through an electric push rod A, a vacuum pump, a dust suction head, and protective plates B and A, determines the welding position, moves the worktable and welding table to the designated location, and then extends the electric push rod A to move the connecting rod, thereby changing the angle between protective plates B and A. This alters the protection range without affecting the welding effect, ensuring that welding debris and slag are trapped within the enclosure formed by protective plates B and A. Simultaneously, the vacuum pump, through the dust suction head and hose, draws welding dust into a collection box, reducing the impact on the working environment. Furthermore, operators can observe the welding process through a viewing window. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figure 1 A welding device for a plate surface tension tank includes a workbench 1 and a welding table 2 disposed on one side of the workbench 1. Brake rollers 3 are fixedly installed on the bottom of both the workbench 1 and the welding table 2. A protective component 4 for protecting the safety of the welding process is provided on the upper surface of the workbench 1.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1:

[0026] Please see Figures 1-4 The protective assembly 4 includes a protective plate A41 fixedly installed on the upper surface of the workbench 1, and a protective plate B42 hinged to one side of the protective plate A41. A mounting base 43 is provided on one side of the protective plate B42. An electric push rod A44 is fixedly installed on one side of the workbench 1. A moving block 45 is fixedly installed on the telescopic end of the electric push rod A44. A connecting rod 46 is hinged to one side of the moving block 45. One end of the connecting rod 46 is hinged to one side of the mounting base 43. A viewing window 47 is provided on one side of the protective plate A41. A dust suction head 48 is provided on the upper surface of both the protective plate A41 and the protective plate B42. A hose 481 is fixedly installed on one end of the dust suction head 48. A vacuum pump 482 is fixedly installed on one end of the hose 481. A collection box 483 is fixedly installed on one end of the vacuum pump 482. This protects the operator from the impact of flying debris during welding and also reduces the impact of dust on the working environment.

[0027] A placement frame 5 is fixedly installed at the bottom of the workbench 1. A partition 51 is provided inside the placement frame 5, which divides the interior of the placement frame 5 into cavity A52 and cavity B. The vacuum pump 482 is placed inside cavity A52, and the collection box 483 is slidably connected to the interior of cavity B. This helps to reduce the space occupied by the equipment and facilitates maintenance and cleaning.

[0028] A light-shielding plate 6 is slidably connected to the outer surface of the protective plate A41. There are five sets of light-shielding plates 6, and the positions of the five sets of light-shielding plates 6 correspond to the viewing window 47. The degree of light shielding and the viewing range can be adjusted according to the actual welding needs.

[0029] The upper surface of the welding station 2 is provided with a receiving box 7. An electric push rod B71 is fixedly installed on the inner wall of the receiving box 7. A brush plate 72 is provided at the telescopic end of the electric push rod B71. One side of the brush plate 72 contacts one side of the viewing window 47, which can remove the residue on the surface of the viewing window 47 in time, keep the field of vision clear, and at the same time make the waste fall into the receiving box 7 for easy cleaning.

[0030] Both protective panels A41 and B42 are components made of composite materials composed of carbon fiber and epoxy resin. Carbon fiber has extremely high strength and rigidity. When combined with epoxy resin, it forms a composite material that is both lightweight and strong. This allows protective panels A41 and B42 to maintain strength while reducing weight, making them easy to handle and install.

[0031] The viewing window 47 is a component made of quartz glass, which can withstand the high temperatures generated during welding and provide high transparency.

[0032] Specifically, after determining the welding position, the workbench 1 and welding table 2 are moved to the designated location. Then, the extension of the electric push rod A44 causes the moving block 45 to move the connecting rod 46, thereby changing the angle between the protective plate B42 and the protective plate A41. This changes the protection range without affecting the welding effect, ensuring that welding debris and slag are blocked by the enclosure space formed by the protective plates B42 and A41. Simultaneously, the vacuum pump 482 sucks the welding dust into the collection box 483 through the suction head 48 and the hose 481, thus reducing the impact on the working environment. Furthermore, the vacuum pump 482 and the collection box 483 are placed in the placement frame 5 at the bottom of the workbench 1, reducing the space occupied and facilitating movement with the equipment. The operator can observe the welding process through the viewing window 47. Additionally, the outer surface of the protective plate A41 is slidably connected to a light-shielding plate 6, which has five sets. The positions of the five sets of light-shielding plates 6 correspond to the viewing window 47, so the degree of light shading and the viewing range can be adjusted according to the actual welding needs. Moreover, since there may be flying debris adhering to the surface of the viewing window 47 during the welding process, in order to prevent the welding process from being interrupted, the brush plate 72 can be driven by the extension and retraction of the electric push rod B71 to brush away the debris, thereby maintaining a clear field of vision and allowing the waste to fall into the receiving box 7 for easy cleaning. In addition, since both the protective plate A41 and the protective plate B42 are made of composite materials composed of carbon fiber and epoxy resin, carbon fiber has extremely high strength and rigidity. When combined with epoxy resin, it can form a composite material that is both lightweight and strong. Therefore, the protective plates A41 and B42 can maintain strength while reducing weight, making them easy to handle and install. Furthermore, since the viewing window 47 is made of quartz glass, it can withstand the high temperature generated by welding and provide high transparency.

[0033] Example 2:

[0034] Please see Figure 2A motor A21 is fixedly installed on one side of the welding table 2. A lead screw A22 is fixedly installed at the output end of the motor A21. A frame 23 is threadedly connected to the outer surface of the lead screw A22. A motor B24 is fixedly installed on the upper surface of the frame 23. A lead screw B25 is fixedly installed at the output end of the motor B24. A mounting block 26 is threadedly connected to the outer surface of the lead screw B25. An electric push rod C27 is set inside the mounting block 26. A welding head 28 is set at the telescopic end of the electric push rod C27. By precisely controlling the position and movement trajectory of the welding head 28, automated welding is achieved, thereby improving accuracy and efficiency.

[0035] Specifically, motor A21 drives lead screw A22 to rotate, causing frame 23 to move laterally inside welding table 2. Then, motor B24 drives lead screw B25 to rotate, thereby adjusting the position of mounting block 26 in longitudinal space. Finally, the extension and retraction of electric push rod C27 causes welding head 28 to contact the welding position, thus realizing the welding work.
