The rope connecting ring 24 is connected to the rope connecting ring 24. In this state, the wire stretching machine runs on the power transmission line as shown in FIG.
8 to move and arrange it.

To explain how to operate the wire drawing machine of the present invention, first, the direction switch 17 attached to the control panel 14 is set to forward (to the right in the drawing). Next, the driver selects manual driving, automatic driving, or wirelessly controlled driving using the control switch 16. For example, when manual travel is selected and set, electric circuits such as the timer 19, sensing switch 22, stop switch 25, solenoid 27, motor switch, etc. are connected to the operating state. Next, when the operation switch 15 is turned on, the timer 19 starts, and when the set time has elapsed, the motor 6 is automatically switched on and the motor 6 rotates, at the same time the solenoid 27 is turned on.
to open the braking mechanism 32. That is, the lever 28 is opened against the spring by the solenoid 27, the disk 30 is released via the cable 29, and the grip on the disk 31 is released, so that the motor 6 rotates and is connected to it via the connecting means 13. The drive rollers 10, 10 are rotated to travel forward on the power transmission line. If you want to stop the wire drawing machine while it is running due to work such as connecting the hanging wheel assembly 47, when you pull the towing rope 48 strongly, the rope connecting ring 24 that connects its tip will resist the spring 23. Rotates in the direction of arrow B, operates the stop switch 25 provided in conjunction with it to turn off the motor switch, simultaneously turns off the solenoid 27, operates the lever 28 with the elasticity of the spring, and the cable 29
The disc 30 grabs the disc 31 through the brake mechanism 32 and stops it on the spot. Simultaneously with this stop, the timer 19 is activated and the stop continues for the set time, and after that time the machine starts moving forward again in the same manner as described above. By repeating this operation, a plurality of hanging wheel assemblies 47 are placed on the power transmission line, and when the wire extending machine reaches the steel tower in front, the sensing lever 21 attached to the front of the frame 1 touches the metal fittings such as the yoke. When the wire drawing machine hits, it rotates in the direction of arrow B, and the sensing switch 22, which is provided in conjunction with this, operates and cuts off the electric circuit necessary for running, so the wire drawing machine stops on the spot, and the operator turns the operating switch 15. of
Turn it off and the driving operation ends.

Next, the case where the control switch 16 is set to automatic travel will be explained. First, the direction switch 17 is set to forward travel. Next, after setting the control switch 16 to automatic, turn on the operation switch 15.
Timer 19 for setting stop time, counter 20 for setting mileage, distance meter 26, sensing switch 22,
Electric circuits for operating the stop switch 25, solenoid 27, motor switch, etc. are electrically connected.

At the same time, the timer 19 works and when the set time has passed, the motor 6 is switched on.
Then, the wire drawing machine moves forward in the same manner as above. The rotation pulse detected by the phototube switch of the distance meter 26 provided in conjunction with the traveling device is sent to the counter 2.
0 is counted, the vehicle travels a preset distance, and stops when a predetermined distance is reached, and at the same time, the counter is reset and the timer 19 is activated. When the time preset in the timer 19 has elapsed, the motor 6 is automatically switched on and the vehicle runs again in the same manner as described above. The wire stretching machine travels on the power transmission line while repeating this operation. Work such as connecting the hanging fishing wheel set 47 is performed during the stopped time. Also, if you need to stop while driving,
When the towing rope 48 is strongly pulled, the stop switch 25 is activated as in the case of manual running, and the towing rope is immediately stopped for the set time of the timer 19, and then the towing rope starts running again. When the vehicle reaches the steel tower in front, the sensing switch 22 is actuated to completely stop the vehicle as in the case of manual travel. Note that the action of the braking mechanism 32 is the same as in the manual operation described above.

Next, the case of wirelessly controlled driving will be explained. First, the control switch 16 is set to the wireless driving position, and then the power switch of the transmitter 33 is turned on. (The antenna is extended.) Next, when the operation switch 15 is turned on, the receiver 34, sensing switch 22, stop switch 25, solenoid 27,
Electric circuits for operating motor switches and the like are electrically activated. For example, when one control rod 35 of the transmitter 33 is tilted to the right, the forward switch is turned on, and when it is tilted to the left, the reverse switch is turned on.
When turned ON, the motor 6 rotates in the indicated direction, and the wire extending machine runs in that direction while the control rod 35 is pushed down. When the control rod 35 is released to return to the neutral state, the stopped state is maintained.

Now, the control rod 35 of the transmitter 33 is tilted to the right to move the transmitter 33 forward, and the hanging wheel set 47 is placed on the power transmission line in the same manner as described above. When stopping the running of the line stretching machine,
In addition to setting the control rod 35 of the transmitter 33 to the neutral position, if the towing rope 48 is strongly pulled, the rope coupling ring 24 rotates and the stop switch 25 is activated to stop it. Further, when the sensing lever 21 attached to the front of the frame body 1 hits an obstacle, the sensing switch 22 is activated and stopped.
When the stop switch 25 and the sensing switch 22 act, the motor 6 is completely switched off, so when you want to run it again, you can move the receiver 34 by tilting the other control lever 36 of the transmitter 33 upward, for example. The motor switch can be reset via the After resetting, press the control stick again at 35.
It can be run by operating the . In this way, the wire stretching machine travels on the power transmission line, and when it reaches a metal fitting such as a yoke of the steel tower in front, the sensing lever 21 hits and the sensing switch 22 is activated, turning off the motor 6 and stopping the machine. 47 is completed, the worker turns off the operation switch 15.
and remove the machine.

In addition, in the case of manual and automatic operation, if the detection switch 22 is activated and the motor 6 is turned off and stopped, the operation switch 15 should be turned off once.
It can be reset by turning it off and then turning it on again. In addition, when operating the tower span continuously, it is necessary to operate manually, or in automatic operation to set the distance setting counter 20 to a value greater than the length of the span in advance, or to operate the transmitter 33 during radio-controlled driving. This is possible by continuing to tilt the control rod 35 in the direction of travel. Also, when reversing, press direction switch 1 in manual or automatic mode.
7 in the reverse direction (to the left in the drawing), and for radio control, simply tilt the control rod 35 of the transmitter 33 to the left regardless of the direction switch 17. However, due to the relationship between the mounting positions of the sensing switch 22 and the stop switch 25, it is better to normally use it in the forward direction and to move it backwards by that amount if necessary for work.

The present invention is configured as described above, and can be operated by selecting manual driving, automatic driving, or radio-controlled driving, so that safe and efficient work can be performed depending on the work location and the content of the construction work. can. Moreover, the distance traveled can be set and controlled by the distance meter 26 and counter 20, and the timer 19
The stop time can be set and the motor switch can be reset by a rope coupling ring 24 and a stop switch 25 linked thereto. The vehicle can be stopped automatically.
In addition, an obstacle detection lever 21 and a detection switch 22 linked thereto are provided, so that when the wire extending machine reaches the target steel tower side, it hits a metal fitting such as a yoke near the insulator and rotates, automatically operating the detection switch 22. The control mechanism for running and stopping allows for safe work.

In addition, a braking device consisting of a solenoid 27 or a disc brake is installed, and the brake is released while the motor is rotating (while driving), and the brake is applied when the motor stops, preventing automatic driving due to the slope of the power line. can be retained. In particular, in the case of radio control, operation can be controlled freely by remote control, which improves work efficiency. Furthermore, since the gripping roller 37 is brought into pressure contact with the power transmission line C by the tension of the spring 43 when the lever 40 is operated, the gripping roller 37 is pressed against the power transmission line C regardless of the thickness of the power transmission line, thereby preventing the drive rollers 10, 10 from slipping. It makes sure that you can run safely. Furthermore, since the present invention is lightweight and compact, it has remarkable effects such as being easy to carry and attaching to and detaching from power transmission lines.
