Description

Technical Field

[0001] The utility model relates to the technical field of submerged arc welding devices, in particular to a submerged arc welding device for installing a propylene spherical tank. Background Art

[0002] Submerged arc welding (SAW) machines utilize an electric arc burning beneath a flux layer to weld. Their inherent advantages, such as consistent weld quality, high welding productivity, and the absence of arc flash and minimal smoke, have made them a key welding machine in the fabrication of pressure vessels, pipe sections, and box beam and column steel structures. Despite the recent emergence of numerous new, high-efficiency, and high-quality welding machines, the application of SAW machines remains unaffected. In terms of the share of deposited metal by weight among various fusion welding machines, SAW machines account for approximately 10%, a share that has remained largely unchanged over the years.

[0003] During submerged arc welding, flux needs to be accumulated at the weld position to form a covering layer to isolate the air and ensure welding quality. During this process, the movement of the welding gun will inevitably push the flux in front of the molten pool horizontally to both sides of the weld. This results in residues on both sides of the weld when the flux is subsequently cleaned for recycling and reuse, making it difficult to completely remove it in one go. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A submerged arc welding device for installing a propylene spherical tank includes a welding mechanism and a cleaning mechanism. The welding mechanism includes a submerged arc welding machine, a bellows fixedly connected to one side of the submerged arc welding machine, a main pipe and a filter element connected to and communicating with the bellows, a negative pressure fan connected to the outer end of the filter element, and a cleaning mechanism. The cleaning mechanism includes a plurality of plates connected to the outer wall of the bellows, a pipe sleeve rotatably connected to the plates, an auxiliary pipe connected to the pipe sleeve, and a hose connected between the bellows and the auxiliary pipe, the hose body passing through the pipe sleeve. A drive assembly is provided on the bellows.

[0007] By adopting the above technical solution, after the submerged arc welding machine completes the welding of the weld, it starts the negative pressure fan, and then the suction force is generated in the bellows. The main pipe connected to the bellows draws the flux directly above the weld, and then the cylinder pushes and pulls the push plate back and forth, which can increase the angle between the transmission rod one and the transmission rod two back and forth. Then, under mechanical transmission, the auxiliary pipe swings left and right, thereby sucking away the flux pushed to both sides by the output end of the submerged arc welding machine, so that the scattered flux can be collected completely and at one time.

[0008] In a preferred example, the present invention can be further configured as follows: the driving assembly includes a cylinder connected to the bellows, a push plate connected to the movable end of the cylinder, two transmission rods 1 and two transmission rods 2 movably connected to the push plate, and the outer ends of the two transmission rods 1 and the two transmission rods 2 are respectively rotatably connected to the inner sides of multiple auxiliary pipes.

[0009] In a preferred example, the present invention can be further configured as follows: the push plate is set to be U-shaped and movably sleeved on the outside of the bellows.

[0010] In a preferred example, the present invention can be further configured as follows: a plurality of plates are grouped in pairs, and are arranged into two groups, with the two groups of plates being respectively close to the top and bottom of the bellows, and the two plates in each group being vertically symmetrical with respect to the bellows.

[0011] In a preferred example, the present invention can be further configured as follows: a T-shaped rod is integrally formed on the top end of the sleeve, and the T-shaped rod movably penetrates the plate body.

[0012] In a preferred example, the present invention can be further configured as follows: a plurality of auxiliary pipes are arranged in a matrix, and the main pipe is arranged between the plurality of auxiliary pipes.

[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0014] In the utility model, after the submerged arc welding machine completes the welding of the weld seam, the negative pressure fan is started, and then suction is generated in the bellows. The main pipe connected to the bellows draws the flux just above the weld seam. Then the cylinder pushes and pulls the push plate reciprocatingly, which can increase the angle between the transmission rod 1 and the transmission rod 2 reciprocatingly. Then, under mechanical transmission, the auxiliary pipe swings left and right, thereby sucking away the flux pushed to both sides by the output end of the submerged arc welding machine, so that the scattered flux can be collected completely and at one time.

[0025] To make the objectives, technical solutions and advantages of the present application clearer, further detailed description will be given below with reference to the embodiments and the accompanying drawings. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] It is understood that the above description is only exemplary and is not intended to limit the scope of the present application.

[0027] Some embodiments of the present application provide a submerged arc welding device for propylene spherical tank installation.

[0028] Embodiment one: combined Figures 1-6 As shown in the drawings, the submerged arc welding device for propylene spherical tank installation comprises a welding mechanism 100 and a cleaning mechanism 200. The welding mechanism 100 comprises a submerged arc welder 110, an air bellow 120 fixed to one side of the submerged arc welder 110, a main pipe 130 and a filter core 140 connected with and communicated with the air bellow 120, and a negative pressure fan 150 connected with the outer end of the filter core 140.

[0029] The cleaning mechanism 200 comprises a plurality of plate bodies 210 connected with the outer wall of the air bellow 120, a pipe sleeve 220 rotationally connected with the plate body 210, an auxiliary pipe 230 connected with the pipe sleeve 220, and a hose 240 connected between the air bellow 120 and the auxiliary pipe 230. The hose 240 penetrates through the pipe sleeve 220, and the air bellow 120 is provided with a driving assembly 300.

[0030] Specifically, the driving assembly 300 includes a cylinder 310 connected to the bellows 120, a push plate 320 connected to the movable end of the cylinder 310, two transmission rods 1 330 and two transmission rods 2 340 movably connected to the push plate 320, and the outer ends of the two transmission rods 1 330 and the two transmission rods 2 340 are respectively rotatably connected to the inner sides of multiple auxiliary pipes 230. The cylinder 310 serves as a power source. After the transmission rod 1 330 and the transmission rod 2 340 are pushed and pulled back and forth by the push plate 320, the angle between the transmission rod 1 330 and the transmission rod 2 340 can be continuously adjusted, thereby pushing and pulling the multiple auxiliary pipes 230, so that the flux on both sides of the weld can be fully collected.

[0031] Furthermore, the push plate 320 is configured to be U-shaped and movably sleeved on the outside of the bellows 120. The shape design of the push plate 320 ensures that it can move horizontally smoothly.

[0032] Furthermore, multiple plates 210 are arranged in groups of two, and are set as two groups. The two groups of plates 210 are respectively close to the top and bottom of the bellows 120. The two plates 210 in each group are vertically symmetrical about the bellows 120. The layout design of the plates 210 limits the installation positions of multiple auxiliary pipes 230, providing conditions for the auxiliary pipes 230 to extract flux from the edges of the welds.

[0033] Example 2: Combination Figures 4-5 As shown, based on the first embodiment, the top of the sleeve 220 is integrally formed with a T-shaped rod, and the T-shaped rod movably passes through the plate body 210. The structural design of the sleeve 220 prevents it from being separated from the plate body 210.

[0034] Example 3: Combination Figure 1 and Figures 4-6 As shown, in the above embodiment, the plurality of auxiliary tubes 230 are arranged in a matrix, and the main tube 130 is disposed between the plurality of auxiliary tubes 230 . The layout design of the auxiliary tubes 230 can improve the cleaning efficiency of the flux.

[0035] The working principle and use process of the present invention are as follows: flux is arranged at the weld position of the propylene spherical tank, and then the flux is inserted into the output end of the submerged arc welding machine 110, and the propylene spherical tank is welded. During this period, the negative pressure fan 150 and the cylinder 310 operate synchronously, and then suction is generated in the bellows 120. The main pipe 130 connected to the bellows 120 extracts the flux just above the weld position, and then the cylinder 310 pushes and pulls the push plate 320 back and forth, which can increase the angle between the transmission rod 1 330 and the transmission rod 2 340 back and forth, and then under mechanical transmission, the auxiliary pipe 230 swings left and right, thereby sucking away the flux pushed to both sides by the output end of the submerged arc welding machine 110, so that the scattered flux can be collected completely and at one time.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
