A stopper 135 for connecting and fixing the pipe member 5 in a closed state is a hanging hook used when the tube material inspection machine 53 is carried into or removed from the common groove 1.

Next, the operation of the above embodiment will be described.

First, when the pipe 5 is suspended from the entrance 2 of the common groove 1 by a crane or the like and placed on the receiving carriage 17 of the pipe feeder 6, the inner frame 14 of the pipe feeder 6 is driven by the telescopic motor 15. When the pinion 16 is driven, the inner frame 14 is extended as shown in FIG.
And is hung over a frame support jig 44 shown in FIG.
The receiving truck 17 on which the tube material 5 is placed is sent out to the front end side of the inner frame 14 by driving the drive sprocket 19 and the chain 20 by the sending motor 18 as shown in FIG.

The opening / closing arm 3 of the tube holder 31 of the tube conveying and supporting machine 7 is opened as shown by the phantom line in FIG.
When the tube 5 is positioned on the pipe 7, the opening / closing arm 37 is rotated about the pin 36 by the contraction operation of the opening / closing cylinder 35, and is moved toward the fixed arm 34 while holding the tube 5. Are supported at three points by the rollers 38, 39 and 42.

When the tube 5 is placed on the tube transporting and supporting machine 7, the inner frame 14 of the tube delivering device 6 contracts and the receiving truck 17 returns to its original position below the entrance 2. After that, the tube material transfer support device 7 on which the tube material 5 is placed
Travels along the transport rail 4 to the installation point.

Here, a counterweight or the like may be provided on the side of the tube material feeder 6 opposite to the tube material transfer support device 7 so that the tube material feeder 6 can be prevented from tipping over when the tube material 5 is sent out, and a pipe is provided at the end of the frame. If it can withstand the load when placed, the inner frame 14 of the tube feeder 6
It is not always necessary to provide the frame support jig 44 for supporting the distal end portion. In the case where the carry-in port 2 of the common groove 1 is provided above the tube material transfer support device 7, the tube material delivery device Needless to say, 6 need not always be provided.

When the tube material transfer supporter 7 on which the tube member 5 is mounted reaches the installation point, first, the slide block 28 shown in FIG. 8 is moved in the lateral direction by driving the ball screw 30 by the motor 29 for lateral movement. Pipe gripper 31
Is moved up and down along the elevating guide 33 by driving the elevating jack 32, and the centering of the tube member 5 ′ is performed on the already installed tube member 5 ′.

When the centering of the tube 5 is completed, the front end of the tube 5 is aligned with the rear end of the installed tube 5 ′.
As shown in FIG. 3 and FIG. 14, a pipe material processing machine 50 is disposed at the tip end of the pipe material 5, and the position adjustment of the gas cutting machine 55 of the pipe material processing machine 50 with respect to the pipe material 5 in the height direction, the lateral direction, and the like is performed. Thereafter, in a state where the flame is radiated from the gas burner torch 68, the pipe member 5 is rotated by driving the roller 42 by the rotation motor 40 of the tube material transporting support machine 7, and the tip of the tube member 5 is cut off. With the torch 68 being tilted at a desired angle about the pin 65, the pipe 5 is rotated by rotating the pipe 5 in the same manner as when cutting, so that the groove of the pipe 5 is processed. The groove processing of the tube 5 can be performed simultaneously with the cutting of the tube 5 by providing another gas burner torch in addition to the gas burner torch 68.

When the cutting and beveling of the tube material 5 are completed, the grindstone 79 of the grinder 56 is rotated by a driving motor 78 while being pressed against the cut surface of the tube material 5 at a desired surface pressure. Rotation motor 40 of transport support machine 7
The rotation of the roller 42 causes the pipe member 5 to rotate, so that the cut surface of the pipe member 5 is finished.
The groove of the tube 5 is finished by rotating the tube 5 while pressing the groove with a desired surface pressure.

In addition, with respect to the rear end of the installed pipe member 5 ',
If the tip of the tube 5 can be joined as it is,
It goes without saying that the tube processing machine 50 does not necessarily need to be used.

When the processing of the pipe material 5 requiring the above processing is completed, the pipe material processing machine 50 is moved to the distal end side of the pipe material 5 'as shown in FIG.
Is moved along the transport rail 4 toward the pipe member 5 ′, and the position of the pipe member 5 ′ is detected by a positioning sensor or the like so that the rear end surface of the tube member 5 ′ and the front end surface of the tube member 5 have an appropriate route interval during welding. , And the pipe welding auxiliary machine 51 is connected to the pipe 5 as shown in FIGS.

After the pipe supporter 49 moves to the rear end side of the pipe 5 so as to pass through the pipe welder 52, the pipe welder 5
The second annular guide rail 105 is closed again, and the welding of the second and subsequent layers is performed in the same manner as the welding of the first layer.

When the welding of the pipes 5, 5 'by the pipe welding machine 52 is completed, the pipe welding machine 52 is moved to the rear end side of the pipe 5 with the annular guide rail 105 opened, and the same operation as described above is performed. Several pipes 5 are added, and thereafter, the pipe inspection machine 53 is connected to the annular guide rail 125.
In the opened state, as shown in FIG.
And as shown in FIG. 20, it is moved to the joint part of the pipe members 5, 5 '.
