Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, and more specifically, the utility model relates to a welding device for a non-negative pressure manifold pipe. Background Art

[0002] The so-called manifold pipe is a pipe fitting assembly formed by welding multiple parallel stainless steel pipes to a vertical stainless steel pipe. The liquids flowing in the multiple parallel pipes are collected into a vertical pipe.

[0003] The current welding solution is as follows: Place the horizontal pipe and the vertical pipe to be welded on the workbench, align the intersection line, and have two people operate the welding. One person holds it firmly by hand to prevent the intersection line position of the two pipes from shifting (the intersection line is previously cut by a laser cutting machine), and the other person holds the welding torch to spot weld and fix the position, and then perform full welding.

[0004] The disadvantages of this solution are as follows:

[0005] ① The pipes are not fixed and rely on being held by hand, which is unstable. The set position is very likely to move, resulting in a deviation between the two intersection lines. As a result, the welded welds are uneven, with inconsistent widths, heights, overburning or incomplete penetration, causing weld leakage and water leakage during the operation of the non-negative pressure equipment.

[0006] ② The time for aligning the intersection line is too long, the work efficiency cannot be improved, and the labor productivity is low. Content of the Utility Model

[0007] To solve the above technical problems, the utility model provides a welding device for a non-negative pressure manifold pipe, which includes an I-beam. A number of sets of latching plate components are arranged on the top of the I-beam. The latching plate components are stuck on the top end of the I-beam and slide back and forth along the top end of the I-beam. An openable clamping device is installed on the top of the latching plate components, and the clamping device is used to clamp and fix the end of the manifold pipe.

[0008] In a preferred embodiment, the latching plate component includes an intermediate latching plate located on the top of the I-beam and a lower latching plate located below the intermediate latching plate. A dovetail groove is embedded at the bottom of the intermediate latching plate, and the dovetail groove is stuck on the top of the I-beam. The lower latching plate is located below both ends of the intermediate latching plate and is clamped on both sides of the I-beam.

[0009] In a preferred embodiment, the clamping device includes a first upper latching plate attached to the top of the intermediate latching plate and a second upper latching plate located on one side of the first upper latching plate. The corners of the first upper latching plate and the second upper latching plate are movably hinged through a hinge.

[0010] In a preferred embodiment, first bolts penetrate through both edges on both sides of the first upper bridging plate. The first bolts sequentially penetrate downward through the middle bridging plate and the lower bridging plate, and the two first bolts are located on both sides of the I-beam.

[0011] In a preferred embodiment, semi-circular pipe grooves are provided at the edges where the first upper bridging plate and the second upper bridging plate are close to each other. Through positioning holes are further provided on the first upper bridging plate outside the pipe grooves, and positioning bolts penetrate between the first upper bridging plate and the middle bridging plate.

[0012] In a preferred embodiment, embedded slots are provided at the edges of the first upper bridging plate and the second upper bridging plate away from the hinged side. A rotating screw rod is installed in the slot of the first upper bridging plate. The screw rod extends into the slot of the second upper bridging plate and extends outward for a certain distance, and a gasket and a nut are installed at the end of the screw rod.

The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0020] As Figures 1-3 shown, a welding device for a non-negative pressure manifold pipe includes an I-beam 1. A number of sets of bridging plate components are arranged on the top of the I-beam 1. The bridging plate components are stuck on the top end of the I-beam 1 and slide back and forth along the top end of the I-beam 1. An openable and closable clamping device is installed on the top of the bridging plate components, and the clamping device is used to clamp and fix the end of the manifold pipe.

[0021] The bridging plate components include an intermediate bridging plate 2 located on the top of the I-beam 1 and a lower bridging plate 3 located below the intermediate bridging plate 2. A dovetail groove 4 is embedded at the bottom of the intermediate bridging plate 2, and the dovetail groove 4 is stuck on the top of the I-beam 1. The lower bridging plate 3 is located below both ends of the intermediate bridging plate 2 and is clamped on both sides of the I-beam 1;

[0022] On the above basis, when installing the device, select an I-beam 1 with a suitable length, calibrate the flatness after quenching and tempering. The length of the I-beam 1 meets the number of vertical manifold pipes 16 to be welded, and the flatness of the I-beam 1 meets the perpendicularity requirements of the vertical manifold pipes 16.

[0023] Design and manufacture the lower bridging plate 3 and the intermediate bridging plate 2. The intermediate bridging plate 2 is milled with a dovetail groove 4 and stuck on the I-beam 1, and can move freely parallel to the I-beam 1;

[0024] The clamping device includes a first upper bridging plate 5 attached to the top of the intermediate bridging plate 2 and a second upper bridging plate 6 located on one side of the first upper bridging plate 5. The corners of the first upper bridging plate 5 and the second upper bridging plate 6 are movably hinged through hinges;

[0025] First bolts 7 penetrate through both sides of the edge of the first upper bridging plate 5. The first bolts 7 sequentially penetrate down through the intermediate bridging plate 2 and the lower bridging plate 3. The two first bolts 7 are located on both sides of the I-beam 1;

[0026] On the above basis, the lower bridging plate 3 is connected below both ends of the intermediate bridging plate 2 through two first bolts 7. The first bolts 7 penetrate through the first upper bridging plate 5, the intermediate bridging plate 2 and the lower bridging plate 3, locking the lower bridging plate 3 and the intermediate bridging plate 2 on the I-beam 1. The openable and closable clamping device clamps the bottom end of the vertical manifold pipe 16. After locking the first bolts 7, the vertical manifold pipe 16 is fixedly clamped.

[0027] The upper bridging plate 1 is connected to the upper bridging plate 2 through a quick clamping device to clamp the vertical manifold pipe 16 to be welded, and lock the bolts, and the manifold pipe is clamped

[0028] Semicircular pipe grooves 8 are respectively opened at the adjacent edges of the first upper bridging plate 5 and the second upper bridging plate 6. A through positioning hole 9 is further opened on the first upper bridging plate 5 outside the pipe groove 8. A positioning bolt 10 also penetrates between the first upper bridging plate 5 and the intermediate bridging plate 2;

[0029] An embedded slot 11 is provided at the edge of the first upper strap 5 and the second upper strap 6 away from the hinge side, and a rotating screw 12 is installed in the slot 11 of the first upper strap 5. The screw 12 extends to the inside of the slot 11 of the second upper strap 6 and extends outward for a distance, and a gasket 13 and a nut 14 are installed at the end of the screw 12.

[0030] Based on the above, one side of the first upper strap 5 and the second upper strap 6 are hinged to realize the opening and closing of the two, and the other side is fixed by the screw 12 rotating in the slot 11 and the gasket 13 and nut 14 at the end of the screw 12 to clamp the vertical manifold 16 to be welded;

[0031] During the process of fixing and installing the first upper strap 5, the middle strap 2 and the lower strap 3 on the I-beam 1, positioning pins can be used to assist in limiting the first upper strap 5 and the middle strap 2 to prevent shaking during the installation process.

[0032] Then place the bottom end of the vertical collector 16 to be welded on the inner side of the tube groove 8, rotate the second upper strap 6 to close it with the first upper strap 5, and then rotate the screw 12 in the slot 11 of the first upper strap 5 to move the screw 12 into the slot 11 of the second upper strap 6, and then rotate the nut 14 and the gasket 13 at the end of the screw 12 to partially lock the screw 12, so as to achieve locking between the first upper strap 5 and the second upper strap 6, and clamp and fix the vertical collector 16.

[0033] Furthermore, the positioning bolt 10 may be inserted into the flange at the end of the vertical manifold 16 through the positioning hole 9 to fix the angle of the vertical manifold 16 on the I-beam 1 .

[0034] On the basis of the above, the first upper strap 5 and the lower strap 3 are connected to the middle strap 2 by two first bolts 7 and can be locked on the I-beam 1;

[0035] The middle slat 2 has a dovetail groove 4 milled inside, which is clamped on the I-beam 1 and moves freely horizontally along the I-beam 1, and moves with the clamped vertical manifold 16 during the movement;

[0036] The flange surface at the lower end of the vertical manifold 16 contacts the plane of the I-beam 1 after modulation and calibration, ensuring that the vertical manifold 16 is in a vertical state;

[0037] Move the middle plate 2 until the intersection line of the vertical manifold 16 and the intersection line of the horizontal manifold 15 are aligned, tighten all bolts, fix the device on the I-beam 1, spot weld the intersection line, and fully weld the weld after spot welding;

[0038] By replacing the specifications and dimensions of each clamping plate, vertical busbars 16 with different diameters can be clamped, ensuring that busbars within a certain diameter range can all be welded.
