Multiple sets of steel pipe clamps 200 are installed on the welding platform 100. When operating the butt joint mechanism of the present invention, the opposite end sides of the two steel pipes 300 are first manually contacted and aligned, and then the steel pipe clamps 200 are used to fix the steel pipes 300.

[0034] The welding platform 100 is provided with a plurality of mounting holes 101 for fixing and mounting the steel pipe clamp 200 .

[0035] As a preference, Figure 1 and Figure 6 As shown, in one embodiment of the present utility model, the steel pipe clamp 200 includes a base 201, and the base 201 is fixedly installed on the welding platform 100 by bolts matching the mounting holes 101; a lower clamp 202 is fixedly provided on the base 201, and the steel pipe 300 to be fixed is placed on the lower clamp 202; the steel pipe clamp 200 also includes a lifting plate 208, and an upper clamp 203 is fixedly provided on the lower surface of the lifting plate 208, and the upper clamp 203 is located directly above the lower clamp 202; a top plate 205 is also fixedly installed on the base 201 through column support, and a fixed screw rod 206 is penetrated by a threaded connection on the top plate 205, and the bottom end of the fixed screw rod 206 is rotatably connected to the lifting plate 208, and an operating handle 207 is provided on the top of the fixed screw rod 206;

[0036] The end of the lifting plate 208 is slidably mounted on the column to guide the lifting plate 208 in its up and down movement process;

[0037] The upper fixture 203 is fixed with a lifting guide rod 204, which slides through and extends into the side inner cavity of the lower fixture 202. The lifting guide rod 204 also guides the upper fixture 203 during its up and down movement.

[0038] When clamping and fixing the steel pipe 300, place the steel pipe 300 on the lower clamp 202, and then manually use the operating handle 207 to drive the fixed screw rod 206 to rotate, and then push the lifting plate 208 downward according to the rotation direction of the fixed screw rod 206, that is, drive the upper clamp 203 downward, thereby fixing the steel pipe 300.

[0039] Furthermore, the large-diameter steel pipe welding and butting mechanism of the embodiment of the present invention also includes a detection module corresponding to the steel pipe 300, which is used to detect the coaxial state of the steel pipe 300 to ensure that the two steel pipes 300 maintain a coaxial state when aligned.

[0040] Among them, each steel pipe 300 corresponds to a detection module, and each detection module includes a first detection device 400 and a second detection device 500. The first detection device 400 and the second detection device 500 are respectively arranged on both sides of the steel pipe 300; it can be understood that the first detection device 400 and the second detection device 500 of this embodiment are only exemplary, and more detection devices can be set to detect different positions on different sides of the steel pipe 300.

[0041] Since the first detection device 400 and the second detection device 500 have the same structure, Figure 1 and Figure 2 The specific structure of the first detection device 400 provided in an embodiment of the present utility model is described.

[0042] The first detection device 400 includes a fixing base 407, which is fixedly mounted on the welding platform 100; optionally, the fixing base 407 is fixed to the welding platform 100 using bolts that match the mounting holes 101;

[0046] During specific use of the first detection device 400 of the embodiment of the present invention, the detection pressure rod 401 is placed on the steel pipe 300. Due to the provision of the torsion spring 402, the detection pressure rod 401 will be tightly attached to the steel pipe 300. At this time, the first scale data indicated by the indicator needle 405 on the scale disk 404 can be obtained; correspondingly, for the second detection device 500, other parts of the steel pipe 300 can be inspected and corresponding second scale data can be obtained; by providing more detection devices, more scale data can be obtained, and by comparing the scale data of different detection devices corresponding to the two steel pipes 300, it can be determined whether the two steel pipes 300 are in a coaxial alignment state.

The adjusting screw 209 passes through the internal threaded through hole 211 set on the lower clamp 202 by a threaded connection. By rotating the adjusting screw 209, the adjusting screw 209 is pushed to move in the vertical direction, so that the support bracket 210 moves upward to push the steel pipe 300 to move, thereby achieving fine-tuning of the steel pipe 300 and ensuring that the two steel pipes 300 are in a coaxial alignment state, which is beneficial to subsequent welding operations.

[0049] It can be understood that a number of mounting holes 101 are provided on the welding platform 100 of the present invention, which are used for the fixed installation of the steel pipe clamp 200 on the one hand; and the pipeline welding equipment can be installed at a designated position on the welding platform 100 as needed to use the pipeline welding equipment to weld the steel pipe 300; accordingly, the mounting holes 101 also facilitate the installation and fixation of multiple first detection devices 400 and second detection devices 500.

[0050] It should be noted that, when the present invention is implemented, the method of aligning first and then fixing is adopted, that is, the two steel pipes 300 are first aligned and contacted at the ends, and then the steel pipe clamp 200 is used to fix the steel pipes 300; of course, the method of fixing first and then aligning can also be adopted. In this method, the steel pipe clamp 200 is installed on the welding platform 100 in a movably manner. In such a structure, the steel pipe 300 is first fixed by the steel pipe clamp 200, and then the hydraulic telescopic rod is used to push the steel pipe clamp 200 to move, so that the steel pipe 300 fixed by the steel pipe clamp 200 is aligned and contacted at the ends.
