DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic construction wiring system for inserting electric wires into pipelines in a building under construction or a road under construction.

[0002]

2. Description of the Related Art Conventionally, when an electric wire, a telephone line, a data transmission line, and the like (hereinafter, generally referred to as an electric wire) are inserted into a building under construction or a road under construction, the road is generally provided with a pipeline. Are buried, and in the case of a building, conduits are attached to the inside of the wall of the building or the ceiling, and the electric wires are inserted into these conduits.

[0003] When inserting an electric wire into this pipeline,
Workers are arranged at both ends of the pipeline, respectively, and a nominal line is inserted through the pipeline in advance. When a worker arranged at the other end of the conduit approaches the above-mentioned nominal line and inserts an electric wire into the conduit, and a tip of the electric wire is exposed at the other end of the conduit, a series of electric wires are connected. Is completed. After the work is completed, a worker arranged at the other end of the conduit breaks the binding between the end of the above-mentioned nominal line and the end of the electric wire to separate them. In this case, the worker arranged at one end of the pipe line breaks the binding of the nominal line and the electric wire because the calling line and the electric wire approached at the other end are caught in the pipe line or at one end of the pipe line. In order to avoid timing, the wire is sent out into the pipeline at the speed of the approaching of the nominal line, but in order to take the timing between the approaching side and the sending side, the worker from one end to the worker on the other side After the screaming signal, the above insertion work is performed.

[0004]

As described above, in the conventional operation of connecting electric wires to a pipeline, it is necessary to arrange two working personnel, one at each end of the pipeline, so that labor costs are increased. In addition to the bulkiness, the force applied to the wires is uneven because the wires are pulled by human power, which leads to a failure in smooth entry of the nominal line into the conduit and the binding of the nominal line and the wire. There was a case where the part was melted in the pipeline. In addition, there was a problem that the connection between the nominal line and the electric wire was troublesome. The present invention has been made in view of the above-described problems, and it is possible to reduce the cost of line work due to the reduction in the number of line work personnel, and it is possible to automate the line work and shorten the work time. It is an object of the present invention to provide a construction automatic wiring device that becomes possible.

In this embodiment, the case where the pipeline 1 is buried in the road 2 is illustrated, but it is needless to say that the pipeline 1 is also applied to a case where the pipeline 1 is provided in a building. In the automatic wiring device of the present embodiment for inserting an electric wire into the conduit 1, as shown in FIGS. 1 and 2, a flexible wire 3 as a nominal wire is wound around a wheel 4, The rotation of a motor 6 is transmitted to a gear 4 b attached to a rotary shaft 4 a of the motor 4 via a transmission gear 5. The motor 6 is installed on the frame 7,
Is fixed on the base plate 8. A plurality of wheels 9 with stoppers are attached to the base plate 8. The base plate 8 can be freely moved by the wheels 9 with stoppers.

[0007] A battery 10 is mounted as a power source below the frame 7.
The rotation of the motor 6 is performed, and power is supplied as an operation power supply of a control device described later. Above this battery 10,
A control panel 11 is disposed on the frame 7. As shown in FIG. 3, the control panel 11 includes a control device 11a and a radio device receiver 11b. This receiver 11b
Is connected to the antenna 12. In this embodiment, a description will be given of a case where radio waves are used as an example of a wireless device. However, a wireless device that transmits and receives ultrasonic waves or irradiates and receives light with a light beam such as a laser beam may be used.

The receiver 11b receives a signal from a transmitter 21 for sending a command signal for rotating the motor 6 in the normal and reverse directions and outputs the signal to the control device 11a. The control device 11a performs forward and reverse rotation control and stop control of the motor 6 based on the control. Further, the control panel 11 also includes a storage device 11c as shown in FIG. This storage device 11c stores the feeding length of the flexible wire 3 when the flexible wire 3 reaches from one end to the other end of the pipe 1 when the flexible wire 3 is inserted into the pipe 1. It is. The unreeling length is measured by a measuring device 11d provided in the control panel 11, for example, when the flexible wire 3 is inserted from one end of the pipeline 1 and reaches the other end thereof.
And the amount of rotation of the rotating shaft of the motor 6 is stored in the storage device 11c. The content stored in the storage device 11c is such that a reverse rotation command signal from the transmitter 21 described below is transmitted via the receiver 11b to the control device 11a. Is input from the storage device 11c to the control device 11a. If the length of the pipeline 1 is known in advance at the construction site, the size of the electric wire 13 inserted into the pipeline 1 may be stored in the storage device based on the length.

When a reverse rotation command signal is input from the transmitter 21, the control device 11a controls the motor 6 to rotate in the reverse direction, and the flexible wire 3 is wound around the wheel 4 by the length stored in the storage device 11c. Then, the motor 6 is controlled to stop driving. When an overload is applied to the motor 6, the protection device (not shown) automatically stops the motor 6. Also, the wheel 4 is
A lid 14a is provided at a predetermined location on the upper part of the casing 14, and the lid 14a can be opened and closed with respect to the casing 14 by a hinge 15.
By opening the lid 14a, the wheel 4 and the like can be inspected.

Further, a substantially U-shaped handle 16 is attached near one end of the base plate 8. By pressing the grip 16 while holding it, the base plate 8 can be freely moved and moved to a desired passage. Also,
Through the casing 14, a handle 17 is attached to the rotation shaft of the wheel 4. The handle 17 is used when manually winding and rewinding the flexible wire 3. When the handle 17 is used, the wheel 4 and the motor 6 are used to reduce the rotation of the wheel 4.
The intermediate transmission gear 5 can be removed from the wheel 4.

On the other hand, in FIG. 1 and FIG.
It is attached to the doorway. The insertion adapter 18 is inserted into one end of the pipe 1 and guides the flexible wire 3 sent out to the pipe 1 and the flexible wire 3 wound up by the wheel 4 and pulled out from the pipe 1. is there. As shown in an enlarged perspective view in FIG. 4, the insertion adapter 18 is formed in a cylindrical shape that gradually tapers as it curves and goes toward the distal end. The insertion adapter 18 has flexibility, and is adapted to be freely adapted to the insertion shape and shape of the conduit 1. Also,
Reference numeral 19 denotes an electric wire drum around which the electric wire 13 is wound. An end 13 a of the electric wire 13 wound around the electric wire drum 19 is connected to a connector 20 attached to an end of the flexible wire 3. .

FIGS. 5A and 5B show an example of the connector 20, FIG. 5A is a side view of the connector 20, and FIG. 5B is a front view thereof. As shown in FIG. 5A, the connector 20 is attached to the distal end of the flexible wire 3 in advance, and the connector 20 has two holes 20a and 20b as shown in FIG. 5B. Then, as shown in FIG. 5C, the distal end 13a of the electric wire 13 is inserted into these two holes 20a and 20b and folded, and the folded distal end is wound around the vicinity of the distal end of the electric wire 13 and fixed. The flexible wire 3 and the electric wire 13 are bound. Here, the description returns to FIGS. 1 and 2 again. Reference numeral 21 shown in FIG. 1 is a transmitter of a wireless device as described above. The transmitter 21 wirelessly transmits a forward rotation instruction and a reverse rotation instruction of the motor 6 to the receiver 11b by an operation of a worker (not shown). And is usually carried by workers.

Next, the operation will be described. According to the present invention, the electric wire 13 wound around the wheel 14 is inserted into the pipeline 1 by one worker. First, one worker pushes the wheel 9 with the stopper by grasping the handle 16 and pressing it. The rolling device is rolled to move the wiring device to a place where the conduit 1 through which the electric wire 13 is inserted, and when it reaches a predetermined position, the stopper of the wheel 9 with stopper is operated to stop the base plate 8. Subsequently, the insertion adapter 18 is inserted into one end of the conduit 1 as shown in FIG. In this state, the motor 6
, The receiver 11b provided on the control panel 11 receives the forward rotation command, and outputs a received signal to the control device 11a. Thus, the control device 11a drives the motor 6 to rotate forward.

When the motor 6 rotates forward, the motor 6
Is transmitted to the speed change gear 5, the speed is changed to a predetermined number of revolutions by the speed change gear 5, and the torque is transmitted to the gear 4 b of the wheel 4 to the rotating shaft 4 a to rotate the wheel 4 forward.
With the forward rotation of the wheel 4, the flexible wire 3 wound around the wheel 4 is paid out and starts to be inserted into the pipeline 1 via the insertion adapter 18. During this time, the worker moves to the wheel 19 while carrying the transmitter 21. Then, the measuring device 11d starts measuring the number of rotations of the motor 6 or the wheel 4 at the same time as the normal rotation of the motor 6 starts, or from the time when the connector 20 starts insertion into the line 1, The length of the pipe 1 and thus the length of the flexible wire 3 inserted into the pipe 1 are measured from the rotation speed of the motor by measuring the time until the wire is exposed. This connector 20 is connected to the pipe 1
The measurement result at the time of exposure from is stored in the storage device 11c.

At the time when the connector 20 is exposed from the pipeline 1, the worker operates the transmitter 21 to transmit a stop command to the motor 6, and the stop command is received by the receiver 11b, and the reception output is controlled. It is sent to the device 11a. Thus, the control device 11a controls the rotation of the motor 6 to stop. As the rotation of the motor 6 stops, the feeding of the flexible wire 3 also stops. At this time, as described above, since the worker has already moved to the wire drum 19 side on which the wire 13 has been wound, the worker attaches the distal end 13a of the wire 13 to the connector 20 as shown in FIG. Fix it. In this state, the operator operates the transmitter 21 again, and sends a reverse rotation command of the motor 6 from the transmitter 21.
This reverse rotation command is received by the receiver 11b,
a, and outputs a received signal to the motor 6 by the control device 11a.
The reverse rotation control is performed. As a result, the motor 6 and the wheel 4 are driven in reverse, and this time the flexible wire 3
Is wound on the wheel 4.

At the same time, the electric wire 13 fixed to the connector 20 is inserted into the conduit 1 and the end 13a of the electric wire 13 comes out to the insertion adapter 18 side of the conduit 1, that is, stored in the storage device 11c. When the flexible wire 3 is wound around the wheel 4 by the specified size, the rotation of the motor 6 is automatically stopped by the control of the control device 11a. After the motor 6 is stopped, the operation of inserting the electric wire 13 into the pipeline 1 is completed by removing the electric wire 13 from the connector 20. During these operations, when the motor 6 is hindered for some reason, such as when the flexible wire 3 is fed or wound, and the motor 6 is overloaded, the rotation of the motor 6 is automatically controlled by the control device 11a. Stop by the control of.

The structure of the connector 20 is shown in FIG.
Instead of the structure shown in FIGS. 6A and 6B, FIGS.
(B). That is, FIG.
6B is a side view of another example of the connector, FIG. 6B is a front view of the same, and FIG. 6C is a side view showing a state where the electric wire 13 is attached to the connector of FIGS. 6A and 6B. . This figure 6
As is clear from (a), (b), and (c), the tip of the flexible wire 3 is connected to one end of the tapered screw 22, and the nut 23 is screwed onto the tapered screw 22, and the right end side of the tapered screw 22. By inserting the tip 13a of the electric wire 13 into the nut and screwing the nut 24, the electric wire 13 is
The connector fixed to 2 has the same effect as the above embodiment.

Further, in each of the above embodiments, the case where the feeding and winding of the flexible wire 3 and the insertion of the electric wire 13 into the pipe line 1 are performed automatically by the drive control of the motor 6 has been described in each case. It is also possible to insert the electric wire 13 into the pipeline 1. In this manual operation, the handle 17 is attached to the rotating shaft of the wheel 4 and the transmission gear 5 is removed, so that the wheel 4 is independent of the transmission gear 5 and the motor 10, and the flexible wire 3 is connected to the pipeline 1. In order to insert the electric wire 13 into the conduit 1, the handle 17 is rotated in the normal direction. If you rotate to
The electric wire 13 can be inserted into the conduit 1. further,
The operation of the transmitter 21 of the wireless device may be performed by a push button, a foot switch, a voice switch, or the like.
