[0019] As attached Figure 1-2 As shown, a welding leveling device includes a base plate 1. Two sets of columns 2 are fixedly connected to the top of the base plate 1. The two sets of columns 2 are preferably symmetrically arranged. Each set of columns 2 includes two symmetrically arranged columns 2. A top bar 3 is slidably installed inside the column 2. A clamping gap is formed between the top bars 3 of the two symmetrical columns 2 for clamping a pipe 4. A sliding groove 11 is provided between the two sets of columns 2. The sliding groove 11 is preferably two as shown in the figure. The two sliding grooves 11 are arranged in parallel and parallel to the length direction of the clamped pipe 4. Each sliding groove 11 is preferably located between the columns 2 on the same side of the two sets of columns 2. A sliding column 5 is slidably connected inside the sliding groove 11. The sliding column 5 is connected to a pressing mechanism.

[0020] Further details are attached. Figure 3 As shown, a sliding space is provided inward on the side of the column 2. The inside of the column 2 is slidably connected to the sliding sleeve 22 through the sliding space. Preferably, as shown in the figure, the top and / or bottom of the sliding space are provided with limiting grooves 21 along the sliding direction of the sliding sleeve 22. The top and / or bottom of the sliding sleeve 22 are provided with sliders that cooperate with the limiting grooves 21. The top bar 3 is preferably L-shaped as shown in the figure. One end of the L-shape is slidably connected to the inside of the sliding sleeve 22. The other end of the L-shaped top bar 3 extends outward and forms a clamping surface. The clamping surface is preferably concave and provided with an anti-slip pad. A stud 33 is provided on the side of the limiting groove 21. One end of the stud 33 is located outside the column 2. The other end of the stud 33 passes through the column 2, extends into the limiting groove 21, and abuts against the top bar 3. Alternatively, the head end of the column 2 can be a smooth rod that is inserted into and rotated to connect the top bar 3. The stud 33 and the column 2 are threaded together to form a tightening screw.

[0021] Furthermore, the top bar 3 includes a right top bar 31 and a left top bar 32, which are respectively located in two sets of columns 2. The end of the right top bar 31 is hinged to one end of the locking bar 34, which is connected by a hinge 35 and preferably by a hinge. The other end of the locking bar 34 is provided with a locking head 341. The end of the left top bar 32 is provided with a hole and groove that cooperates with the locking head 341. The direction of the hole and groove is set along the direction of rotation of the locking head 341, so that as the locking bar 34 rotates, the locking head 341 can slide into the hole and groove along the circumferential trajectory of rotation, so that the movement will not interfere.

[0022] Further details are attached. Figure 3 As shown, the sliding column 5 is a threaded column, with a sliding groove 11 slidably connected to its bottom end. The top end of the sliding column 5 extends upward from the base plate 1 and is threadedly connected to a rotating sleeve 6. A retaining sleeve 61 is rotatably connected to the top of the rotating sleeve 6, and a limiting sleeve 7 is fixedly connected to the top of the retaining sleeve 61. The limiting sleeve 7 is plate-shaped, with an arc-shaped protrusion in the middle for pressing against the top of the pipe 4. Preferably, a retaining sleeve 61 is fixedly connected to each end of the limiting sleeve 7, and the rotating sleeve 6 and the sliding groove 11 are sequentially fitted to form a gate-shaped structure. The pressing mechanism formed by the limiting sleeve 7 is provided with at least one... The set is preferably set in two groups, as shown in the figure. The top of the rotating sleeve 6 extends inward along the inner edge, and the bottom of the retaining sleeve 61 is rod-shaped. The rod-shaped structure passes downward through the hole between the inner edges and extends outward along the outer edge, so that the two are rotatably connected and form a limit in the vertical direction. The top of the retaining sleeve 61 has a threaded groove, and a screw 62 is threaded inside the threaded groove. The surface of the limiting sleeve 7 has an adapter groove at the position corresponding to the screw 62. The screw 62 is adapted to the adapter groove, and the limiting sleeve 7 is fixedly snapped into the outer ring of the screw 62 and the top of the retaining sleeve 61.

[0023] Furthermore, the inner walls on both sides of the slide groove 11 are recessed to form a strip slide groove 12, and the bottom of the slide column 5 is a hexagonal head 51. The hexagonal head 51 is hexagonal, and both sides of the hexagonal head 51 extend into the strip slide groove 12, so that the slide groove 11 limits the hexagonal head 51 in the vertical direction.

[0024] This pipe welding leveling device adapts to pipes of different diameters by setting up structures such as columns 2, sliding sleeves 22, and top bars 3. The two pipes 4 to be welded are placed between the top bars 3. By rotating the studs 33, the gap between the top bars 3 is gradually reduced, clamping the pipes 4 between the top bars 3 and initially fixing the position of the pipes 4. When welding pipes 4 of different diameters, since the sliding sleeve 22 acts as an extension sleeve of the top bars 3, the top bars 3 can adapt to pipes 4 of different diameters, thus achieving the effect of adapting to pipes 4 of different diameters.

[0025] The pipe welding leveling device uses a structure including a sliding groove 12, a sliding column 5, and a limiting sleeve 7 to assist welding. After fixing, there may be upturned edges at the opening of the pipe 4. Pulling the retaining strip 34 exposes the weld joint between the pipes. The limiting sleeve 7 is moved to the opening of the upturned pipe by sliding the sliding column 5 and the rotating sleeve 6. If both pipe 4 ends are upturned, the two limiting sleeves 7 are moved to the different pipe 4 ends for limiting. Rotating the rotating sleeve 6 gradually lowers its position, causing the limiting sleeve 7 to squeeze the upturned pipe 4, aligning the upturned pipe 4 with the non-upturned pipe 4. Welding can then be performed, thus achieving the effect of assisting welding.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
