Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a pipe conveying device with good transportation efficiency that can collectively convey a large number of bent pipes in a pipe bending factory or the like.

[Prior Art] Conventionally, when transporting a pipe that has been bent at a pipe bending factory, etc., it is difficult to determine the center of gravity of the bent pipe. After hooking the pipes C one by one onto the hook d of an overhead crane (not shown) and transporting them to a predetermined location, the worker a had to repeat the process of removing the pipes C one by one from the hook d.

[Problems to be Solved by the Invention] However, transporting pipes in the manner described above not only incurs large labor costs and time losses during transport, but also requires continuous pipe assembly processes using a series of flow production methods. There were also problems, such as having a negative impact on

Means for Solving the Problems] The present invention is intended to solve the above-mentioned problems.
A hanging beam suspended from a crane, a plurality of swing beams whose central portions are rotatably supported via a hanging cart that moves in the longitudinal direction of the beam along the hanging beam, and a vibrator holding device attached to the swing beams. and a magnet as the pipe holding device.

[Function] By adjusting the spacing between the rotating beams according to the length of the pipe to be transported, it is possible to transport many types of pipes with uneven lengths at once, and by moving the rotating beam in the longitudinal direction of the hanging beam. It is possible to eliminate the shift in the center of gravity of the entire pipe in the pipe length direction, and it is also possible to stably transport a large number of pipes by rotating the rotating beam and holding the pipes with the pipe holding device crossing the pipes at right angles. . Furthermore, by configuring the pipe holding device with a magnet, a large number of pipes can be magnetically attached instantly, thereby saving labor and greatly shortening transportation time.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
The figures to FIG. 5 show a first embodiment of the present invention.
In the figure, 1 is a box-shaped suspension boom suspended from a hook 3 of an overhead crane (not shown) via a suspension row 12; 4 is a suspension boom that moves along the suspension beam 1 in the longitudinal direction; A suspension carriage 6 that supported the parts in a rotatable manner is a pipe holding device suspended from each swing beam 5.

As shown in FIG. 3, each suspension truck 4 is equipped with wheels 8 that run on a flange 7 provided on the side of the suspension beam 1, a pivot shaft 10 on which a swing beam 5 is suspended via a thrust bearing 9, and a rotating shaft 10 that is attached to these wheels. It consists of a frame 12 having an octopus-shaped cross section.

Each frame 12 has a winding 491 provided on the hanging beam 1.
One end of a chain (not shown) driven by 3.13 is connected, and when the chain is driven using each winder tR13, each hanging carriage 4 moves along the hanging beam 1, and each winding machine 13.13 is supplied with power via a cable junction box 26.

In order to lock the turning beam 5 at a desired turning angle position,
As shown in FIG. 4, an operating lever 1G is provided which has a spur gear-shaped brake wheel 14 with teeth carved around its semicircumference and a pawl 15 that engages in the tooth groove of the brake wheel 14 in a manner that allows it to fit and detach. , the brake wheel 14 is fixed to the swing beam 5, and the operating lever 16 is pivotally mounted to a pin 17 fixed to the frame 12.

Next, the handling procedure for this device will be explained.

When lifting pipes, in order to transport as many pipes as possible at once, the pipes 25 are placed close to each other and parallel to each other (see Figure 5). The distance t between the rotating beams 5.5 is adjusted appropriately depending on the length. In order to securely hold the pipes with the holding device 6, the holding device 6 turns the swing beams 5, 5 so as to be perpendicular to each pipe 25, and then lowers them onto the pipes 25 (see Fig. 2). 14 to lock the swing beam 5.5 (see FIG. 4).

Since it is difficult to predict the center of gravity position 30 (see FIG. 2) of the entire vibrator held, the shift in the center of gravity is corrected as follows so that the center of gravity position 30 is directly below the 7-piece 3. For this purpose, first, the entire transport device and the vibrator held therein are slightly lifted using an overhead crane, and some of the pipes are placed in an inclined state where one side is in contact with the ground and the other side is lifted up. When the swing beams 5, 5 are moved in the longitudinal direction of the hanging arm 1 (arrow h), the shift in the center of gravity in the vertical plane including the hanging beam 1 is removed. In this state, the deviation of the center of gravity in the direction perpendicular to the vibrator has not yet been removed, so if you lift the part that has touched the ground and move the pipe 25, conveyance device, hook 3, etc. in the direction perpendicular to the pipe (arrow i), the center of gravity of the vibrator will be located at 30.
is directly below hook 3. At this time, each swing beam 5 and each holding device 6 are slightly inclined, but the deviation of the center of gravity in the direction perpendicular to the pipe is small compared to the deviation in the length direction of the pipe, and compared to the height of the overhead crane. is sufficiently small that the inclination of the holding device 6 is very small and does not adversely affect the holding of the pipe. Now that preparations for transportation are complete, the pipes 25 are lifted to a predetermined height and transported to a predetermined location. After that, the pipes are removed from the holding device 6, and all the pipes 25 are lowered to the ground in the same arrangement as when they were originally lifted. It will be done.

Next, a second embodiment of the present invention will be described with reference to FIGS. 6 to 8. In this example, the pipe holding device in the first embodiment is configured with magnets, and the magnet 6a is fixed to a beam-shaped core 19 with a hollow chamber 18 of rectangular cross section attached to the lower side, and to both sides of the core 19. hollow chambers 22, each i 18, 22.2, supported by brackets 20° 20 and extending parallel to each side of said hollow v 18;
The head 23 extends into the room through a slot provided on the lower surface of the magnetic head 2, and has a head 23 projecting on both sides, and is composed of a large number of magnetic pole pieces 24 arranged adjacent to each other.

The thickness of each magnetic pole piece 24 is set so that when a pipe 25 is magnetically attached as described later, several magnetic pole pieces 24 for each pipe move upward as appropriate and almost surround the upper half of the pipe. (See Figure 8).

In the figure, 27 is a connection box for cables that supply power to each magnet 6a.

Next, the operation of the magnet 6a will be explained.

Pipes 2 arranged in line on the ground as shown in Figure 5
Lower the magnet 6a so that it is perpendicular to the top of the magnet 5. Here, each 11FjA piece 24 is pushed upward by the pipe 25 located below the magnetic pole piece (as indicated by the arrow), and several magnetic pole pieces 24 almost surround the upper half of the pipe (see Figure 8).
. When the magnet 6a is energized and the core 19 is magnetized, a magnetic flux 28 with a high density is generated (see Fig. 7), and the pipe 25 is connected to the magnet Oak:! Let them wear a.

Note that the present invention is not limited to the above-described embodiments, and various changes may be made without departing from the gist of the invention, such as the possibility of providing three or more sets of rotating beams and pipe holding devices. Of course.

[Effects of the Invention] As described above, the present invention exhibits the following excellent effects.

(1) Since the swing beam can be moved in the longitudinal direction of the hanging beam, by adjusting the spacing between the beams, pipes of uneven length can be conveyed all at once.

G) For the same reason as in item (1), it is possible to eliminate the shift in the center of gravity of the pipes in the longitudinal direction, and it is possible to transport a large number of pipes in a stable state.

0 Since the pivot beam can pivot relative to the hanging beam, the pipe holding device can be lowered onto the pipe perpendicularly to the pipe, and therefore a large number of pipes can be stably held.

) By using magnets, many pipes can be instantly magnetically attached. Therefore, it is possible to save labor and improve transportation speed.
