Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable drawing method and a cable drawing apparatus, and more particularly to a cable drawing method and a cable drawing apparatus suitable for drawing a new cable in a building such as a power plant. .

[0002]

2. Description of the Related Art Conventionally, tens of thousands of cables have been extended in a building of a power plant represented by a thermal power plant or a nuclear power plant. The length of the cable extended into these buildings is more than 1 kilomail, and the control panel and other devices are connected to each other for signal transmission.

The following method is known as a method of extending such a cable. FIG. 8: is explanatory drawing which shows the work of the cable drawing using a ball drawing machine. As shown in FIG. 1 (1), the ball drawing machine 1 is composed of a pair of rotatable balls 2.
Cable 3 to be extended in the space (gap between balls 2)
Is taken in and the ball 2 is rotated, so that the cable 3 can be sent out along the extending direction (see arrow 4 in the drawing).

When the ball drawing machine 1 is arranged at an arbitrary interval along the extending direction of the cable 3 as shown in FIG. 2B, the cable 3 sandwiched by the ball drawing machine 1 becomes
The cable 3 is sent out in the direction of the arrow 5 (that is, the wire extension path) (and the tip of the cable 3 is pulled by the leading conductor 6), and the cable 3 is extended.

However, in the ball drawing machine 1 described above, the distance between the balls 2 is fixed, so that if the outer shape of the cable changes, the amount of pinching of the cable changes. For this reason, when a large-diameter cable is used, excessive pinching may occur, and the cable may be damaged (breakage or the like). On the other hand, if a small-diameter cable is used, the amount of pinching becomes small, and there is a possibility that the cable cannot be reliably sent out. Needless to say, it is not possible to send out multiple cables at the same time.

And for such a ball drawing machine 1,
As disclosed in Japanese Examined Patent Publication No. 2-59097, there is known a wire drawing device that is not affected by the outer diameter of a cable and can pull a plurality of cables at the same time. This is one in which two types of gripping tools that are curved toward the other side are mounted on a carriage that can be reciprocated, and during wire drawing work, the gripping tool grips a cable and moves the carriage.
Then, after the movement of the carriage is completed, the grip of the cable is released and the carriage is returned to the origin. If you repeat such work,
The cable can be reliably extended regardless of the outer diameter of the cable or the number of cables.

[0007]

However, when the above wire drawing device is used, there are the following problems. That is, when a cable is sent out using the wire drawing device, a series of operations for returning the origin of the moving carriage gripping of the cable gripping carriage gripping the carriage are repeatedly performed, so that the cable sending out is intermittent. . For this reason, it is not possible to synchronize with the cable drum rotating machine on the feeding side of the cable, and when the wire gripping device releases the grip of the cable, tension (back tension) is applied to the cable from the feeding side. Cable, the tension could pull the cable back.

The present invention focuses on the above-mentioned conventional problems, and provides a cable drawing method and a cable drawing apparatus capable of continuously feeding these cables regardless of the outer diameter and the number of the cables. With the goal.

[0009]

According to the present invention, a plurality of wire drawing devices capable of gripping a cable are arranged along a wire drawing path,
This is based on the knowledge that the cable can be continuously fed out by operating these wire drawing devices with a time lag.

That is, in the cable drawing method according to the present invention, a cable for drawing a wire is staggered in a pin row composed of a plurality of pins.
Arrange in two rows so that the pin rows are narrowed
The wire extension cable is deformed in a meandering shape to be gripped and moved from the origin, and after the movement is completed, the grip of the wire extension cable is released and the origin is returned, and this is repeated. At this, the cable drawing work for sending out the cable for wire drawing is performed at a plurality of points, and by giving a time difference to the cable wire drawing work at the plurality of points, the cable for wire drawing is continuously sent out. did.

Further, the cable drawing apparatus according to the present invention has a row
Arrange multiple pins in a staggered pattern in two rows
Place the pins in a row and narrow the row spacing of the pins
By sandwiching the extension cable, the extension cable is
A plurality of cable drawing machines that have a moving means that deforms into a line shape and grips is provided, and that enables the feeding of the cable for drawing wire, and the plurality of cable drawing machines are operated with a time difference. The controller is connected, and the cable drawing machine is operated by an instruction from the controller to enable continuous feeding of the drawing cable.

A plurality of the cable drawing machines are arranged as one unit and a plurality of the units are arranged,
The controller may be made to perform synchronous operation for each unit, and further, the cable drawing machine is provided with hubs for transmitting and receiving operation signals from the gripping means and the moving means, and these hubs are provided with bus lines. The controller may be connected to the cable drawing machine via the bus line by connecting the controller via the bus line.

[0013]

[0014]

According to the present invention configured as described above, the wire-extending cable can be fed out by gripping the wire-extending cable and moving from the origin. Here, in a single cable drawing machine, after grasping the drawing cable and moving it from the origin, the grip of the drawing cable is released and the origin is restored, so the sending of the drawing cable is intermittent. However, during the wire drawing work, the plurality of cable drawing machines operate with a time lag so as not to stop the sending of the wire drawing cable, so that the wire drawing cable can be sent continuously.

Since a controller is connected to the cable drawing machine, when an operation signal is transmitted from the cable drawing machine to the controller, the controller receives the operation signal and the controller receives another operation. Give operation instructions. In this way, since the other cable drawing machines operate by using the operation signal from the cable drawing machine as a trigger, the drawing cable can be continuously sent out.

A plurality of cable drawing machines arranged in one
A unit and multiple units are arranged.
And if you try to operate these units synchronously,
Since the wire-drawing cable can be sent out by each unit, the wire-drawing cable can be reliably sent out even in a long wire-drawing path. The synchronous operation between the units is performed by a command from the controller, and the trigger signal at this time may use the operation signal from the cable for wire extension that constitutes the unit.

In order to connect each arranged cable drawing machine to the controller, it is necessary to draw wires from the gripping means and the moving means and connect them to the controller, which may increase the number of wires. And hubs (concentrators) that send and receive operation signals from the moving means are provided, and if a controller is connected to these hubs via bus lines, they will be linked to the numbers assigned to each cable drawing machine. Since the operation signal is transmitted to the controller or the hub via the bus line, it is possible to prevent an increase in wiring due to the addition of the cable drawing machine without disturbing the synchronous operation.

Further, if the gripping means is arranged in two rows so that the pin rows composed of a plurality of pins are arranged in a zigzag arrangement, the interval between the pin rows can be narrowed, so that the extended line sandwiched between the pin rows is formed. The cable for use is meshed with the pins arranged in a zigzag manner, and is formed in a meandering shape, and is gripped by the pins. When the pins are separated from each other, the wire extension cable changes from a meandering shape to a linear shape, and the grip is released. If the pressing and releasing are repeated using the pin row in this manner, the concentrated stress is not applied to the cable for wire extension, and the grasping can be released from one direction.

The main configuration is the controller 14 for control that has been performed.

Then, the cable for wire drawing 18 drawn from the cable drum 16 is pulled by a not-shown conductor and the cable drawing machine 12 is used.
It is designed to be sent to the position of the control panel 20 by and. Further, the above-described controller 14 operates each cable drawing machine 12 with a time lag so that the cable drawing machines 12 arranged along the drawing path can continuously send out the drawing cable 18. I am trying.

FIG. 2B is an enlarged view of the main part of the extended wire path. As shown in FIG. 2B, a gutter-shaped cable storage tray 22 is formed along the wire extension path, and the cable drawing machine 12 is attached to the edge of the cable storage tray 22. Then, after the cable for wire drawing 18 is sent out by the cable drawing machine 12, the cable for wire drawing 18 is removed from the cable drawing machine 12 and stored in the cable storage tray 22.

FIG. 2 is an explanatory view showing the structure of the cable drawing machine 12. As shown in FIG. 1A, the cable wire drawing machine 12 has a gripping device that serves as a gripping means for gripping and releasing the wire drawing cable 18, and reciprocates the gripping device along the wire drawing direction. It is composed of a moving device as a moving means.

In the gripping device for gripping the extension cable 18, pillars 26 are attached to the upper surfaces of a pair of rod-shaped blocks 24L and 24R at equal intervals (four in the figure). The pillar 26 is attached to the pair of block bodies 24L and 24R at positions shifted by a half pitch, and the block body 24L and the block body 24R are attached.
Pillars 2 mounted on top of each other when contacted with
The six do not interfere with each other.

Further, connecting rods 28L and 28R are provided on the sides of the pair of block bodies 24L and 24R, and the tips of the connecting rods 28L and 28R are inside the mechanism portion 12A of the cable drawing machine 12. It is attached to an air cylinder (not shown) provided. The connecting rod 28L is operated by operating the air cylinder (not shown).
And the connecting rod 28R
Pull in to the A side. This operation is performed by connecting rod 28
Block body 2 connected to L and 28R
The distance between 4L and 24R can be reduced. Further, when the block bodies 24L and 24R are separated from each other, this time, the connecting rod 28R may be projected and the connecting rod 28L may be pulled toward the mechanism section 12A. By reciprocating the air cylinder in this manner, it is possible to move the connecting rods 28L and 28R and repeat contact and separation of the block bodies 24L and 24R. The block body 24L is formed with a through hole larger than the outer diameter of the connecting rod 28R. The connecting rod 28R is inserted into the through hole, and the tip of the connecting rod 28R is attached to the mechanical portion. Since it is attached to the 12A side, the connecting rod 28R can operate the block body 24R without being affected by the operation of the block body 24L.

The air cylinder for operating the connecting rods 28L, 28R is mounted on a slider (not shown) inside the mechanism section 12A. The slider is
Reciprocating movement is possible along the longitudinal direction of the mechanism portion 12. Thus, by synchronizing the operation of the gripping device, the wire-drawing cable 18 can be gripped and sent forward. An air cylinder is used for the moving device that reciprocates the slider, similar to the gripping device.
Further, by using air cylinders for the actuators of the gripping device and the moving device, it is possible to unify the power sources, and it is possible to improve response characteristics and reduce weight by using air as compared with the electric type.

FIG. 2B shows a side view of the block body 24R. As shown in FIG. 2B, a column 26 is attached to the upper surface of the block 24R. The column 26 has a so-called drum shape in which the central portion of the column is constricted. When the pillars 26 approach each other, a closed space is formed by the outer edges of the pillars 26, and the cable 1 for wire extension is formed.
8 can be included. Therefore, the cable 18 for wire extension
Even if there are multiple cables, the wire extension cable 18 that is not gripped
All the cables 18 for wire extension are contained in the closed space without causing the occurrence, and the grip can be surely performed. A rubber member is used on the surface of the pillar body 26, that is, a portion that comes into contact with the wire-drawing cable 18, so that the wire-drawing cable 18 is reliably gripped, and the wire-drawing cable 18 is damaged by gripping. I try to prevent it.

FIG. 3 is an operation explanatory view showing a procedure in which the above cable drawing machine 12 sends out the drawing cable 18. Explaining the procedure of sending the cable 18 for wire drawing from the left side to the right side in the figure, as shown in FIG. 1A, first, in the cable drawing machine 12, the cable 18 for wire drawing is divided into blocks 24L, 24R. Insert it in between,
The gripping device of the cable drawing machine 12 is released.
That is, the block bodies 24L and 24R are separated from each other, and
Increase the space of 6.

After the extension cable 18 is inserted between the block bodies 24L and 24R in this way, as shown in FIG.
The space between L and 24R is narrowed, and the pillar 26 is extended to the cable 18
The wire-drawing cable 18 is sandwiched by being pressed against. If the cable 18 for wire extension is sandwiched between the pillars 26 in this way, the cable 1 for wire extension
The column 8 is pressed by the column 26 so as to be deformed in a meandering shape (not actually deformed) to obtain a gripping force, and is fixed to the gripping device.

After gripping the wire-drawing cable 18 as shown in FIG. 2B, a moving device (not shown) is operated as shown in FIG. 3C to move the block body from the left side to the right side in the figure. Move 24L and 24R. Along with the movement of the block bodies 24L and 24R, the cable 18 for wire extension held by the column body 26 also moves from the left side to the right side in the drawing.

After moving the block bodies 24L and 24R as shown in FIG. 3 (3) and sending out the cable 18 for wire drawing, the block body 24L is shown in FIG. 4 (4). , 24R are separated from each other, and the cable for wire extension 1
Release the grip of 8. Then, the pressing of the wire extension cable 18 from the column is released, so that the wire extension cable 18 can be freely inserted between the block bodies 24L and 24R. After the gripping device releases the wire-drawing cable 18, the gripping device may be returned to the origin position shown in FIG. Further, by repeating the operations from (1) to (4) in the figure, the cable 18 for wire extension can be sent out.

FIG. 4 is an operation explanatory view showing a procedure for arranging three cable drawing machines 12 along the drawing cable 18 and sending the drawing cable 18 as one unit. In the figure, three cable wire drawing machines 12 are arranged along the wire drawing path, and this is regarded as a single unit 30. Note that the cable drawing machine 12 has a movable range within a range indicated by a dimension A in the drawing, and allows the block bodies 24L and 24R to reciprocate within the movable range.

Then, as shown in FIG. 1A, the individual cable drawing machines 12 are operated with a time difference. That is, when the cable drawing machine 12 on the left side of the drawing is located at the origin that is the leftmost end of the movable range, the cable drawing machine 12 in the center of the drawing has already grasped the drawing cable 18 and The wire extension cable 12 is sent out in the line direction. Further, the cable drawing machine 12 on the right side of the drawing completes the feeding of the drawing cable 12 at the same point and is located on the rightmost side of the movable range.

FIG. 2B shows a state in which a predetermined time has elapsed from the state shown in FIG. That is, the cable drawing machine 12 on the left side of the drawing grasps the drawing cable 18 and extends the drawing cable 18 to the central portion of the movement range.
Is being sent out. Then, the cable drawing machine 12 in the center of the drawing completes the sending out of the drawing cable 12,
The cable drawing machine 12 located on the rightmost side of the movable range and further on the right side of the drawing performs origin return from the rightmost side of the movable range, and is located on the leftmost end of the movable range.

FIG. 3C shows a state in which a predetermined time has elapsed from the state in FIG. 2B. That is, the cable drawing machine 12 on the left side in the drawing has completed feeding of the drawing cable 18 and is located on the rightmost side of the movable range. At the same time, the cable drawing machine 12 in the center of the figure is
The origin return is performed from the rightmost side of the movable range and is located at the leftmost end of the movable range. On the other hand, the cable wire drawing machine 12 on the right side of the drawing grips the cable 18 for wire extension from the origin position and moves in the moving range. The cable 18 for wire extension is sent to the central portion.

Thus, these three cable drawing machines 1
If 2 is operated with a time lag, cable 1 for wire extension
No. 8 is sent out by any of the three cable drawing machines 12, so that the wire drawing cable 12 is not sent out intermittently and can be sent out continuously. Therefore, even if a back tension is applied to the cable 18 for wire drawing from the feeding side of the cable 18 for wire drawing, since the cable 18 for wire drawing is continuously fed, the cable 18 for wire drawing is suddenly backed up. The cable body will not be pulled back due to tension. Further, since it is possible to continuously feed the wire-drawing cable 18, it is possible to synchronize with the not-shown lead conductor and the cable drum 16. If a plurality of units 30 including the three cable drawing machines 12 are arranged along the wire extension path and the units 30 are operated synchronously, the wire extension cable 18 can be reliably extended even if the wire extension path is extended. Can be sent out.

FIG. 5 is a drawing cable 1 described with reference to FIG.
It is explanatory drawing which shows the structure of the cable drawing apparatus 10 for achieving continuous feeding of 8, and FIG. 6 shows the enlarged view of the cable drawing machine 12 in FIG.

As shown in FIG. 5, the cable drawing device 10
Is a plurality of (10 in the figure) cable drawing machines 12,
A main configuration is a controller 14 that issues an operation command for these cable drawing machines 12, and the controller 14 and a plurality of the cable drawing machines 12 are control cables 32 (2-core type, see FIG. 6) that are bus lines. ) Is connected. Further, the cable drawing device 10 is provided with a small air compressor 34 (hereinafter, referred to as a compressor 34), and an air supply pipe 36 is drawn out from the compressor 34, and is connected to each cable drawing device 12. Air is supplied by using the lead-in pipe 38.

By the way, as shown in FIG. 6, the air cylinders are used for the gripping device 36 and the moving device 38 in the cable drawing machine 12 as described above. Solenoid valve). This solenoid valve is a 4-port 2-position switchable type that allows the air cylinder to reciprocate, and one GND terminal is used as its control terminal.
A terminal and two direction control terminals are provided. By applying a voltage based on the ground voltage from the outside of the solenoid valve to the direction control terminal, the solenoid valve is switched to enable the air cylinder to reciprocate.

A hub 40 is connected to the gripping device 36 and the moving device 38 having such an electromagnetic valve. Here, the hub 40 can control the output of voltage from an output port provided in advance in the hub 40 according to a signal from the outside, and this output port and various terminals provided in the solenoid valve are provided. Is connected using the connection wire 42 and the connection wire 44, the solenoid valve can be controlled by the hub 40, that is, the gripping device 36 and the moving device 38 can be controlled.

By the way, the hub 40 is connected to the control cable 32 pulled out from the controller 14 so that it can control the output port by receiving a signal sent from the controller 14. Hub 40
Are individually attached to the plurality of cable drawing machines 12, so in order to operate an arbitrary hub 40, the individual IDs (Identifica
must be assigned in advance. For this reason, the hub 40 is provided with a DIP switch or the like so that an ID number can be set for each person, and a single control cable 32 pulled out from the controller 14 can be used to specify and operate any hub 40. It has become.

FIG. 7 is an explanatory diagram showing the contents of the output signal sent from the controller 14 to the hub 40 via the control cable 32. As shown in the figure, the output signal 46 sent to the hub 40 has an ID number 48 added to the beginning thereof. This is for causing the output signal 46 to be sent to an arbitrary hub 40, and the output signal 46 sent to the control cable 32 is received by the hub 40 whose ID number 48 matches. A terminating resistor (terminator), not shown, is attached to the tip of the control cable 32, and the output signal sent to the control cable 32 is output by the control cable 32.
I try to prevent it from bouncing at the tip of.

Then, in the output signal 46, the ID number 4
8, the gripping signal (grip release signal) 50 in the gripping device 36 and the origin movement signal 52 in the moving device 38.
And a home return signal 54, or an emergency stop signal 56 and other signals 58 follow. When an arbitrary hub 40 receives the output signal 46 having such a transmission order, the hub 40 controls the output of the voltage from the output port according to the output signal 46 and operates the gripping device 36 and the moving device 38. . After the gripping device 36 and the moving device 38 are operated by the hub 40, a reply signal is sent from the hub 40 to the controller 14. The reply signal is a gripping signal (grasping signal) in the gripping device 36.
In addition, it is a completion signal of origin movement or origin return, and the controller 14 can detect an abnormality in the feeding of the wire drawing cable 18 based on the time difference between the output signal 46 and the reply signal. That is, when the time difference between the output signal 46 and the reply signal becomes larger than the set value in the arbitrary hub 40, it is determined that the wire pulling cable 18 has a poor grip or a poor feed. When the controller 14 determines that such an abnormal situation has occurred, the controller 14 concerned
Sends an output signal 46 including an emergency stop signal to all the cable drawing machines 12 to cause the cable drawing machines 12 to make an emergency stop.

The cable drawing device 1 configured as described above
The operation of continuously sending out the wire-drawing cable 18 will be described using 0. As described above, the unit 3 includes the three cable drawing machines 12 arranged continuously along the drawing path.
Set to 0. Then, in the unit 30, as shown in FIG. 4, any one of the cable drawing machines 12 may grasp the drawing cable 18 and send it out. In this operation method, the controller 14 sends the output signal 46 to another cable drawing machine 12 after receiving a reply signal from any cable drawing machine 12 in the unit 30. The output signal 46 may be sent to each cable drawing machine 12 based on the timing.
If the operations of the cable drawing machines 12 are synchronized with each other in this way, the cable drawing machines 12 can be operated with an arbitrary time difference, and the drawing cables 18 can be continuously sent out. it can.

Further, by synchronizing the operations of the adjacent units 30, even if the wire extension path is extended, the wire extension cable 1
You can send out 8. The adjacent units 30
In order to synchronize the operation of the cable drawing machine 12, the cable drawing machine 12 in another unit 30 may be operated with reference to the output signal 46 or the reply signal of the cable drawing machine 12 in the unit 30.

As described above, when the controller 14 is used to operate the other cable drawing machines 12 synchronously with the output signal 46 or the reply signal to the cable drawing machine 12 as a reference, the hub 40 is not used and each cable drawing machine is operated. It is also possible to individually wire the line machine 12 to the controller 14 and perform the operation by logic control. However, each cable drawing machine 1
2 is controlled by logic, the gripping device 3
6 or all the terminals of the solenoid valve provided with the moving device 38 and the like must be connected to the controller 14, and the wiring becomes very complicated. Further, in the above control method, since the individual cable drawing machines 12 are directly operated, it is very difficult to replace, add or delete the cable drawing machines 12. On the other hand, if the hub 40 is used and the hub 40 and the controller 14 are connected by the control cable 32, only the control cable 32 needs to be wired from the controller 14, and the cable wire drawing machine 12 can be replaced.
Addition and deletion can be dealt with only by changing the ID of the hub 40, and it is possible to deal flexibly with the convenience of the wire drawing work site.

In this embodiment, the output signal 4
Although 6 has a format as shown in FIG. 7, it is not limited to this format, and the order of various signals may be changed according to the convenience of the device.
