[0026] See also Figures 1 to 5 , the pipeline welding support tooling provided by the utility model is now described. The pipeline welding support tooling includes two support seats 10, two arch seats 30, two positioning sleeves 50 and a positioning rod 60. The two support seats 10 are arranged opposite to each other in the horizontal direction, and a horizontally extending strip angle iron 20 is provided on the top. The strip angle iron 20 is opened upward and is used to support the steel pipe 1; the two arch seats 30 are respectively arranged above the two support seats 10 and straddle the top of the steel pipe 1. The arch seats 30 are arranged near the adjacent ends of the two strip angle irons 20. The arch seats 30 are provided with a locking piece 40 for locking the position of the steel pipe 1; the two positioning sleeves 50 are respectively arranged at the lower part of the two support seats 10 along the direction of the strip angle iron 20, and have relative openings; the positioning rod 60 is arranged between the two positioning sleeves 50, and the two ends are respectively plugged and matched with the two positioning sleeves 50.

[0027] The embodiment of the present application provides a pipeline welding support tool. During its actual use, two support seats 10 are first placed opposite to each other, and two steel pipes 1 to be welded are respectively placed on two strip angle irons 20 and inserted into their corresponding arch seats 30. Then, the positioning rods 60 are respectively inserted into the two positioning sleeves 50, so that the two steel pipes 1 (two support seats 10) are quickly aligned, and finally the locking piece 40 locks the position of the steel pipe 1, thereby improving work efficiency.

[0028] Compared with the prior art, the pipeline welding support tooling provided in this embodiment places two support seats 10 opposite to each other, and places two steel pipes 1 to be welded on two strip angle irons 20 respectively and penetrates into their corresponding arch seats 30, and then respectively inserts the positioning rods 60 into the two positioning sleeves 50, so that the two steel pipes 1 (two support seats 10) can be quickly aligned, thereby improving work efficiency.

[0029] In a possible implementation, the positioning sleeve 50 is as follows: Figure 1 The structure shown, see Figure 1 Two groups of positioning sleeves 50 are arranged at intervals along a direction perpendicular to the strip angle iron 20 , and two positioning rods 60 are provided, which are respectively plugged and matched with the two groups of positioning sleeves 50 .

[0030] Specifically, each positioning rod 60 is plugged into and matched with two positioning sleeves 50 in each group. By plugging the positioning rod 60 into the positioning sleeve 50, the two support seats 10 can be quickly aligned, that is, the two steel pipes 1 can be aligned, without repeatedly adjusting the support seats 10.

[0031] The two positioning rods 60 are respectively plugged and matched with the two groups of positioning sleeves 50 in a one-to-one correspondence, thereby enhancing the stability of the relative position fixation of the two support seats 10.

[0032] In a possible implementation, the locking member 40 is configured as follows: Figures 1 to 4 The structure shown, see Figures 1 to 4 The locking member 40 is a screw rod, which passes through the top of the arch seat 30 in the up-down direction and is threadedly connected to the arch seat 30 . The lower end of the screw rod is used to abut against the outer peripheral wall of the steel pipe 1 .

[0033] Specifically, after the two steel pipes 1 are aligned, the screw is rotated so that the lower end of the screw abuts against the outer wall of the steel pipe 1 , thereby locking the position of the steel pipe 1 , thereby achieving rapid locking of the position of the steel pipe 1 .

[0034] In some embodiments, see Figures 1 to 4 Two guide rods 41 that slide with the arch seat 30 are penetrated through the top of the arch seat 30 in the up and down directions. The two guide rods 41 are respectively located on both sides of the screw. The lower end of the guide rod 41 is connected to an upwardly arched arc plate 42. The screw can push the arc plate 42 downward to abut against the outer wall of the steel pipe 1 to lock the position of the steel pipe 1.

[0035] Specifically, the arc plate 42 can increase the contact area with the steel pipe 1 on the basis of the screw rod, and better fix the steel pipe 1. The setting of the guide rod 41 can limit the arc plate 42, so that the arc plate 42 can only move up and down, avoiding the rotation of the arc plate 42, and facilitating the screw rod to push the arc plate 42 down.

[0036] In some embodiments, see Figures 1 to 4 The arch seat 30 passes through the strip angle iron 20 downwards and slides with the strip angle iron 20 up and down. The arch seat 30 is fixed by a fixing piece 70.

[0037] Specifically, if the steel pipe 1 is heavy and long and it is inconvenient to pass through the arch seat 30 fixed on the strip angle iron 20, the arch seat 30 can be separated from the strip angle iron 20 by removing the fixing piece 70, first place the steel pipe 1 on the strip angle iron 20, adjust the position of the steel pipe 1, then install the arch seat 30, and fix the position of the steel pipe 1, thereby improving practicality.

[0038] In some embodiments, see Figures 1 to 4 The two outer side walls of the strip angle iron 20 are provided with wing plates 21 extending outward, the arch seat 30 is downwardly penetrated through the wing plate 21, and the side of the arch seat 30 is horizontally penetrated with two locking holes 321 spaced apart in the up and down directions. The two locking holes 321 are respectively located above and below the wing plate 21, and the fixing member 70 is a U-shaped pin shaft, which is clamped on the upper and lower sides of the wing plate 21, and the two ends are respectively inserted into the two locking holes 321.

[0039] Specifically, both the strip angle iron 20 and the wing plate 21 have holes for penetrating the arch seat 30 .

[0040] When the arch seat 30 needs to be installed, the arch seat 30 is inserted into the holes on the strip angle iron 20 and the wing plate 21, so that the two locking holes 321 are respectively located on the upper and lower sides of the wing plate 21, and then the U-shaped pin is clamped on the upper and lower sides of the wing plate 21, and its two ends are respectively inserted into the two locking holes 321, so as to lock the position of the arch seat 30;

[0041] When the arch seat 30 needs to be disassembled, the arch seat 30 can be disassembled by simply pulling out the U-shaped pin shaft, which is convenient for disassembly and improves practicality.

[0042] In some embodiments, see Figures 1 to 4 The arch seat 30 includes an arch plate 31 and two connecting rods 32. The arch plate 31 is arranged above the strip angle iron 20 and is arched upward. The screw and the guide rod 41 are both arranged on the arch plate 31; the two connecting rods 32 are respectively connected to the two ends of the arch plate 31 and penetrate downward through the strip angle iron 20 and the corresponding wing plate 21. There are two groups of locking holes 321, which are respectively located on the two connecting rods 32.

[0043] Specifically, each group of locking holes 321 includes two locking holes 321 spaced apart along the axial direction of the connecting rod 32 , and a U-shaped pin is correspondingly passed through each group of locking holes 321 to increase the connection stability between the arch seat 30 and the strip angle iron 20 .

[0044] The setting of the arched plate 31 facilitates the threaded installation of the screw; the two connecting rods 32 respectively pass through the two wing plates 21 in a one-to-one manner. The setting of the connecting rods 32 can facilitate the setting of the holes on the strip angle iron 20 and the wing plate 21 for the connecting rods 32 to pass through, thereby improving practicality.

[0045] In a possible implementation, the support seat 10 is as follows: Figure 1 and Figure 5 The structure shown, see Figure 1 and Figure 5 The two supporting seats 10 are provided with supporting seats 80 for supporting the tail end of the steel pipe 1 on both sides facing away from each other.

[0046] Specifically, the supporting seat 80 is used to support the two opposite ends of the two steel pipes 1 to prevent the steel pipes 1 from protruding too far from the outer ends of the strip angle irons 20, causing the welding ends of the steel pipes 1 to warp upward, thereby improving practicality.

[0047] In some embodiments, see Figure 1 and Figure 5 The supporting seat 80 includes a bottom plate 81, a supporting strip plate 82 and a top plate 83; the supporting strip plate 82 is connected to the top of the bottom plate 81 and extends upward; the top plate 83 is connected to the upper end of the supporting strip plate 82 and extends along the direction of the strip angle iron 20, and a receiving groove 831 is provided on the top of the top plate 83 and extends horizontally to both ends of the top plate 83.

[0048] Specifically, the receiving groove 831 is used to accommodate the steel pipe 1, which is convenient for the placement of the steel pipe 1; the bottom plate 81 is used to contact the ground to increase the stability of the support; the supporting strip 82 is used to increase the height of the top plate 83; the supporting seat 80 can be supported on the tail end of the steel pipe 1 when needed, and can also be removed when not needed, thereby improving practicality.

[0049] In a possible implementation, the support seat 10 is as follows: Figure 1 and Figure 3 The structure shown, see Figure 1 and Figure 3 The support seat 10 includes two groups of legs 11 and a reinforcement rod 12. The two groups of legs 11 are arranged at intervals at the bottom of the strip angle iron 20 along the direction of the strip angle iron 20. Each group of legs 11 includes two legs 11 symmetrically arranged on both sides of the strip angle iron 20, and the legs 11 extend outward and downward; the two ends of the reinforcement rod 12 are respectively connected to the two legs 11 of a group of legs 11 close to the arch seat 30, and the positioning sleeve 50 is connected to the top of the reinforcement rod 12.

[0050] Specifically, the two groups of legs 11 are respectively arranged near the two ends of the strip angle iron 20, and the two adjacent groups of legs 11 on the two strip angle irons 20 are provided with reinforcement rods 12. The two ends of the reinforcement rods 12 are respectively connected to two legs 11 in a group of legs 11, and are arranged in the horizontal direction. They are not only used to reinforce the current group of legs 11, but also facilitate the installation of the positioning sleeve 50.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
