When the pipe welding device 100 welds two pipes PR and PF connected to each other in the operation of FIGS. 2 to 7 with each other, the pipe welding device 100 fixes these pipes PR and PF in a centerline aligned state. It is characterized in that the position is adjusted in the vertical direction in the longitudinal direction or transverse direction of the pipe to be fusion-bonded.

And, in front of the pipe fusion device is provided with a pipe conveying device for transferring the subsequent pipe unit (PR) to the pipe fusion device 100. This pipe conveying apparatus is schematically shown in FIG. 2, and as shown in detail in FIGS. 9 to 11, a traction bar 23 installed laterally at a rear end of a subsequent pipe unit PR, and a pipe fusion apparatus. A winding drum 25 is provided on the left and right sides of the 100 and rotated by the drive motor 26 and the chains 28A and 28B, and one end is fixed to both ends of the tow bar 23. The other end consists of a traction wire 24 wound on the winding drum 25 as the winding drum 25 rotates to pull the subsequent pipe unit PR towards the pipe fusion apparatus 100.

In addition, the pipe moving forward by the transfer device is a large diameter and the ring weight (W) is mounted on the outer circumference is heavy. Therefore, it is preferable that a brake device is provided to stop the rotation of the winding drum in order to stop the movement of the pipe accurately at a predetermined position.

The brake device is coupled to the brake hydraulic cylinder 33 installed in the upright direction and the piston rod tip of the hydraulic cylinder 33 as shown in FIGS. 9 to 11 when the hydraulic cylinder 33 is extended.

After the preceding pipe PF and the subsequent pipe unit PR are fused and joined to each other, the upper clamp of the clamp 111 fixing the preceding pipe PF and the subsequent pipe unit PR is removed to fix the pipes. (Fig. 6)

Then, the pipes (PR, PF) fusion-bonded to each other is forwarded by the pipe feeder at a time. At this time, the ring weight W of the subsequent pipe unit PR is passed through without hitting the side of the clamp 111 of the clamping part 110, and the conveyance guide part to roll guide the outer circumferential surface of the ring weight W as it passes. Move the 120 to the position of the clamping unit 110.

That is, as shown in FIGS. 10 and 11, the four lifting hydraulic cylinders 102 are contracted to lower the lifting plate 103 and the clamp 111 disposed on the upper portion thereof so that the front tip of the clamp 111 is lowered. Do not interfere with the outer circumferential surface of the subsequent pipe unit PR. In this state, the lateral positioning hydraulic cylinder 107 is extended to reverse the mounting plate 109 on which the clamping unit 110 is mounted, and the transfer guide 120 is moved forward of the subsequent pipe unit PR. Let's do it.

Then, the four lifting hydraulic cylinders 102 are extended so that the lifting guide roller 121 of the conveying guide 120 contacts the ring weight W of the subsequent pipe unit PR. And raise the conveyance guide 120 disposed on the upper portion.

Then, the pipe feeder is driven to move the subsequent pipe unit PR until the rear end of the subsequent pipe unit PR is positioned at the position of the two clamps 111 in front of the clamping part 110. When the rear end of the subsequent pipe unit PR reaches the vicinity of the front two clamps 111, the hydraulic cylinder 33 of the brake device is extended to bring the brake pad 34 to the ring weight W of the subsequent pipe unit PR. Friction contact with the outer circumferential surface of the) to stop the movement of the subsequent pipe unit (W).

Then, the four lifting hydraulic cylinders 102 are again contracted, and then the lateral positioning hydraulic cylinders 107 are contracted to move the clamping unit 110 to the position where the next subsequent pipe unit PR is to be fixed. The four lifting hydraulic cylinders 102 are then extended so that the clamping portion 110 can secure the next subsequent pipe unit PR. The process described above is repeated to produce a pipeline extending to a predetermined length.
