A stopper for connecting and fixing 5 in a closed state, and 135 are suspension hooks used when the pipe material inspection machine 53 is carried into the common groove 1 or removed.

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

First, when the pipe material 5 is hung from the carry-in port 2 of the common groove 1 by a crane or the like and placed on the trolley 17 of the pipe material sending machine 6, the inner frame 14 of the pipe material sending machine 6 is driven by the expansion / contraction motor 15. The pinion 16 is driven to extend as shown in FIG.
While being hung on the frame support jig 44 shown in
The trolley 17 on which the pipe member 5 is placed is sent to the tip 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 trolley 17 is sent to the tip side of the inner frame 14 and is opened and closed as indicated by the phantom line in FIG.
When the pipe material 5 is located on the pipe 7, the opening / closing arm 37 is rotated around the pin 36 by the contraction operation of the opening / closing cylinder 35, and the pipe material 5 is moved to the fixed arm 34 side while being held. Is in a state of being supported at three points by the rollers 38, 39 and 42.

When the pipe material 5 is placed on the pipe material conveying / supporting device 7, the inner frame 14 of the pipe material feeding device 6 contracts and the carriage 17 returns to the original position below the carry-in port 2. Then, after this, the pipe material conveying / supporting machine 7 on which the pipe material 5 is placed
Travels along the transport rail 4 to the installation point.

Here, a counterweight or the like is provided on the side of the pipe material feeder 6 opposite to the pipe material conveying / supporting device 7 so that the pipe material feeder 6 can be prevented from tipping over when the pipe material 5 is fed, and a pipe is attached to the tip of the frame. When it can bear the load when placed, the inner frame 14 of the pipe material feeder 6
It is not always necessary to provide the frame support jig 44 for supporting the distal end portion, and in the case where the carry-in port 2 of the common groove 1 is provided on the upper side of the pipe material conveying / supporting machine 7, the pipe material sending machine. It goes without saying that 6 is not necessarily provided.

When the pipe material carrier 7 on which the pipe material 5 is placed reaches the installation point, first, the slide block 28 shown in FIG. 8 is moved in the horizontal direction by driving the ball screw 30 by the horizontal movement motor 29, and at the same time, Pipe material gripping tool 31
Is moved up and down along the up-and-down guide 33 by driving the up-and-down jack 32, and the tube material 5 is centered with respect to the already installed tube material 5 '.

When the centering of the pipe material 5 is completed, the tip end portion of the pipe material 5 is aligned with the rear end portion of the installed pipe material 5'on site, and when the pipe material 5 needs to be machined, as shown in FIG.
As shown in FIG. 3 and FIG. 14, the pipe material processing machine 50 is arranged at the tip of the pipe material 5, and the position of the gas cutting machine 55 of the pipe material processing machine 50 is adjusted with respect to the pipe material 5 in the height direction, the lateral direction, and the like.

When a sensor or the like detects that the backing jig 96 has reached the joint portion of the pipe materials 5 and 5 ′, the welding auxiliary device 94 is stopped and the hydraulic pressure sent from the hydraulic unit 95 causes the backing wave to be used. The backing jig 96 is expanded in the radial direction, and the joint portions of the pipe members 5 and 5'are straightened so as to form a perfect circle.

When the backing jig 96 for backing is inserted into the joint portion of the pipe members 5 and 5 ', the pipe member holding the annular guide rail 105 in an open state as shown by a phantom line in FIG.

Fixed by 3.

When the annular guide rail 105 is set, the welding carriage 108 moves the orbiting motor 109 while adjusting the leading angle and the vertical position of the welding torch 111.
Driving the traveling roller 110 causes the pipe material 5, 5 ′ to circulate along the annular guide rail 105.
The first layer is welded at the 5'seam.

When the welding of the first layer at the joint portion of the pipe materials 5 and 5'is completed, the backing backing jig 96 contracts in the radial direction, and the welding auxiliary device 94 causes the supporting member of the pipe material welding auxiliary machine 51 to support. 90 While returning to the top, the annular guide rail 10
After the pipe 5 is once opened, the pipe material grasping tool 31 of the pipe material conveying / supporting machine 7 on the front end side of the pipe material 5 and the pipe material 5, 5 ′ by the pipe material grasping tool of the pipe support device 49 on the rear end side of the pipe material 5 ′ shown in FIG. Is released from the support state, the pipe supporter 7 and the pipe support 49 move to the rear end side of the pipe 5, and the pipe support 49
The rear end portion of the pipe material 5 is supported by the pipe material 5, and the supporting state of the pipe material 5 by the pipe material gripping tool 31 of the pipe material transport supporting machine 7 supporting the rear end side of the pipe material 5 is released. 7 is connected to the connecting arm 136 of the pipe material conveying / supporting machine 7 with the traveling motor 24, and the frame supporting jig 44 is accommodated between the two, and the pipe material conveying / supporting machine without a drive device. 7 and the frame support jig 44 support the tip end side of the pipe member 5 for traveling motor 24

When the pipe inspection machine 53 is moved to the joint portion of the pipes 5 and 5 ', a magnet check (not shown) with a film is attached to the inspection target portion, and the lifting jack 121 is driven. As a result, the lifting table 122 is moved up and down, and the lateral feeding table 123 is moved in the lateral direction perpendicular to the pipe materials 5 and 5 ′ by the driving of the lateral feeding motor 124,
The position of the X-ray generator 131 is adjusted with respect to the joint portion of the pipe members 5 and 5 ', and thereafter, the opening / closing tandem cylinder 1 is opened.
When 26 is extended, the annular guide rail 125 is closed so as to clamp the pipe member 5 ′ as shown in FIG. 20, and is fixed by the stopper 134.

When the annular guide rail 125 is set, the inspection carriage 128 moves the outer circumference of the pipe material 5'along the annular guide rail 125 by driving the traveling roller 130 by the orbiting motor 129, and the film 180
The X-ray generator 131 is installed at the opposite position, and X-ray imaging is performed on the joint portion of the pipe materials 5 and 5 '. still,
X-ray photography is not always performed on all the pipe materials 5 and 5 '.

Thereafter, the same work as described above is repeated, and the pipe materials 5 are successively added.

In this way, it becomes possible to mechanically handle the installation work of the piping, which relied entirely on human power, and it is possible to significantly reduce the burden on the worker and to improve safety and work efficiency. Is possible.

The pipe installation apparatus of the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the scope of the present invention.

[0056]

As described above, according to the pipe installation device of the present invention, it is possible to reduce the burden on the worker and to improve the safety and work efficiency.
