A T-shaped movable adjustment seat 51 is slidably connected to the plurality of slide rails 52 . A locking assembly 53 is commonly provided on the plurality of T-shaped movable adjustment seats 51 .

[0047] Reference Figure 4A locking hole 43 is provided at the rotation connection between the clamping member 41 and the fixed adjustment seat 42. The fixed adjustment seat 42 is fixedly connected to the top wall of the corresponding T-shaped movable adjustment seat 51. The T-shaped movable adjustment seat 51 is correspondingly engaged and connected to the side walls of the two adjacent rectangular members 2 of the base 11.

[0048] Reference Figure 4 and Figure 8 The locking assembly 53 includes a second locking hole 531 and a second positioning hole 532. The middle part of the top wall of the rectangular part 1 of the base 11 is provided with a second locking hole 531 and a second positioning hole 532.

[0049] Reference Figure 2 , Figure 3 and Fig. 9 The stabilizing mechanism 6 includes an L-shaped stabilizing member 61, and the bottom wall of the ceiling 13 and the top walls of the two rectangular members of the four bases 11 are slidably connected with four L-shaped stabilizing members 61; the middle part of the L-shaped stabilizing member 61 is respectively connected to the corresponding front side plate 121, rear side plate 122, left side plate 123 and right side plate 124 by bolts.

[0050] Reference Figure 4 , Figure 5 , Figures 9 to 11 The upper part of the side wall of the L-shaped stabilizer 61 is fixedly connected with a rack 62 corresponding to the adjustment component 33, and the lower part of the side wall of the L-shaped stabilizer 61 is fixedly connected with a locking bolt 2 64 corresponding to the locking hole 1 43 through an extension plate 63.

[0051] After all the preparations are completed, the T-shaped movable adjustment seat 51 is manually pushed toward the middle of the base 11 from the front, back, left and right directions of the base 11 at the same time. The T-shaped movable adjustment seat 51 slides inside the slide rail 52 until it is engaged with the side wall of the rectangular part 2 of the base 11. At this time, the T-shaped movable adjustment seat 51 completely enters the slide rail 52.

[0052] During the movement of the T-shaped movable adjustment seat 51, the clamping parts 41 which are engaged at the bottom of the front side panel 121, the rear side panel 122, the left side panel 123 and the right side panel 124 rotate around the fixed adjustment seat 42, and the front side panel 121, the rear side panel 122, the left side panel 123 and the right side panel 124 gradually change from a tilted state to a vertical state. At the same time, the adapter tubes 34 corresponding to the front side panel 121, the rear side panel 122, the left side panel 123 and the right side panel 124 rotate around the adjustment cylinder 31 and push the ceiling 13 to rise vertically along the positioning column 22. The base 11, the side panel assembly 12 and the ceiling 13 can be assembled into a three-dimensional structure from a flat structure only by manually pushing the T-shaped movable adjustment seat 51. There is no need to use a lifting equipment to lift the ceiling 13 for installation, which can achieve quick installation and save installation costs.

[0053] Insert the second positioning column 534 into the corresponding second positioning hole 532 on the base 11, and at the same time, insert the second positioning column 534 into the corresponding second positioning hole 532 on the T-shaped movable adjustment seat 51. The locking plate 533 and the second positioning column 534 limit the positions of the four T-shaped movable adjustment seats 51 on the base 11. The locking bolt 535 is screwed into the locking plate 533 and the locking hole 531 to achieve the locking of the position of the locking plate 533. At this time, the positions of the T-shaped movable adjustment seat 51 and the base 11 are relatively fixed, which reduces the amount of bolts used and further improves the connection stability between the T-shaped movable adjustment seat 51 and the base 11.

[0054] The L-shaped stabilizer 61 is slidably installed between the ceiling 13 and the rectangular part 2 of the four bases 11. The four L-shaped stabilizers 61 are fixed to the front side panel 121, the rear side panel 122, the left side panel 123 and the right side panel 124 by bolts. The L-shaped side walls of the four L-shaped stabilizers 61 limit the adjacent front side panel 121 and the left side panel 123, the front side panel 121 and the right side panel 124, the left side panel 123 and the rear side panel 122, and the rear side panel 122 and the right side panel 124 respectively.

[0055] During the movement of the L-shaped stabilizer 61, the rack 62 is driven to engage with the corresponding adjusting gear 331, driving the adjusting gear 331 to rotate, and the adjusting gear 331 drives the rotating shaft 332 and the adjusting block 1 333 to rotate. After the adjusting block 1 333 rotates to contact the adjusting block 2 335, it pushes the adjusting block 2 335 and the limit block 334 to move. The spring is compressed, and the limit block 334 changes from being in the inner cavity of the adjusting cylinder 31 to partially sliding to the outside of the adjusting cylinder 31. The limit block 334 slides through the adapter tube 1 34 to lock the position of the adapter tube 1 34 on the adjusting cylinder 31. At this time, the positions of the ceiling 13 and the front side panel 121, the rear side panel 122, the left side panel 123 and the right side panel 124 are relatively fixed.

[0056] When moving, the L-shaped stabilizing member 61 drives the extension plate 63 to move toward the corresponding fixed adjustment seat 42 until the locking bolt 2 64 engages into the corresponding locking hole 1 43 on the clamping member 41 and the fixed adjustment seat 42. The locking bolt 2 64 locks the position of the clamping member 41 and the fixed adjustment seat 42. At this time, the positions of the T-shaped movable adjustment seat 51 and the front side panel 121, the rear side panel 122, the left side panel 123 and the right side panel 124 are relatively fixed, which further improves the connection stability of the T-shaped movable adjustment seat 51, the base 11, the side panel assembly 12 and the ceiling 13 while reducing the amount of bolts used.

[0057] Reference Figure 1-Figure 12 The specific operation steps of the pipeline welding protection device are as follows: first, prepare, place the base 11 on the horizontal ground, place the ceiling 13 on the base 11, insert four positioning columns 22 downward into the corresponding positioning holes 23 on the ceiling 13 and connect them with the threaded holes 21, place the front side plate 121, the rear side plate 122, the left side plate 123 and the right side plate 124 on the side of the ceiling 13, and connect them to the ceiling 13 through the adjustment tube 31, and connect them to the base 11 through the clamping member 41 and the T-shaped movable adjustment seat 51.

[0058] After all the preparations are completed, the T-shaped movable adjustment seat 51 is manually pushed toward the middle of the base 11 from the front, back, left and right directions of the base 11 at the same time, and the front side panel 121, the rear side panel 122, the left side panel 123 and the right side panel 124 gradually change from a tilted state to a vertical state, and push the ceiling 13 to rise vertically along the positioning column 122. The base 11, the side panel assembly 12 and the ceiling 13 are assembled into a three-dimensional structure by a flat structure. The locking plate 533 and the positioning column 2 534 simultaneously limit the positions of the four T-shaped movable adjustment seats 51 on the base 11, and the L-shaped stabilizing member 61 is slidably installed between the ceiling 13 and the rectangular member 2 of the four bases 11. While limiting the front side panel 121, the rear side panel 122, the left side panel 123 and the right side panel 124, the position of the adapter tube 1 34 rotating around the adjustment cylinder 31 is locked, and the position of the clamping member 41 and the fixed adjustment seat 42 are locked.
