る。2. Description of the Related Art A high-voltage railway line is used to supply electric power for commercial use at a station building and electric power for operating a traffic signal, and as shown in FIG. 8, above a trolley line T for supplying electric power to a train. Or, it is erected by two routes on the upper side. In this way, the two routes are provided so that even if one cannot transmit power for some reason, the other normally operates the traffic signal so that the operation of the train is not hindered.

ものである。In the case of an old Japanese railway company, the high-voltage line W is usually considerably shorter than a general transmission line.
I try to change the time of about a year. In this way, the replacement is performed in a short time in order to further improve the safety of railway operation by replacing the wires before the deterioration of the electric wires leads to a situation where an accident is likely to occur.

て来ている。Conventionally, the replacement of the high-voltage wire W is performed by a construction method generally called a drawing construction method. However, with this construction method, a large slack is generated in the old line being removed and the new line being extended, and this slack electric wire may come into contact with the trolley wire T and the running train E. Therefore, when the high-voltage line W is above the trolley line T, naturally, the construction cannot be performed during the traveling time of the train. Also, considering that rolling may occur due to sudden strong winds, etc. even when it is on the upper side, construction during the running time of the train is not preferable,
Even if it is done during the running time, it is necessary to select a time zone where the number of trains is as small as possible, and to allocate sufficient personnel to monitor the approach of the train at all times. In other words, with the conventional construction method, the working hours are limited to the limited hours at night, and the number of necessary personnel is inevitable. However,
Due to recent changes in the working environment, it has become difficult to secure sufficient work personnel for work under such restricted conditions, and a drastic improvement in the construction method has become an urgent issue.

ものである。The present invention has been made against such a background, and there is no restriction on the workable time zone, and it is possible to change the electric wire in a sufficiently safe state even during the traveling time of the train. The purpose is to provide a method for replacing the high-voltage line for railways that enables more efficient construction.

り換えを簡単に行え、より一層作業の合理化を図れる。This construction method was constructed by paying attention to the fact that the high-voltage line of the railway mentioned above can be re-installed in a short cycle of about 15 years. Since it is re-installed in this short cycle, the degree of deterioration is small and the strength is sufficient. By using the old line holding the cable as a support line for the new line extension, construction can be performed efficiently, without affecting the trolley wire or traveling train, that is, without time constraints. It was done like this. In other words, since the old wire is used as a support wire for the new wire extension, the work of deploying and removing the support wire for the new wire extension can be omitted, and the work can be rationalized accordingly, and the support wire is also supported. The new line and the old line are removed while being supported by a plurality of movable wagons, so there is no significant slack in the new line and the old line. It does not affect the running train. In addition, the utilization of such an old line and a new line as a support line is performed only by the work of interchangeably holding the old line and the new line by an intermediate supporter having the old line holding portion and the new line holding portion. Therefore, the removal of the old line and the extension of the new line can be performed continuously, and the switching from the removal of the old line to the extension of the new line can be easily performed to further rationalize the work.

By combining the semi-circular grooves 6 and 7 of the strips with the semi-circular grooves 8 and 9 of the strips provided on the pressing plates 4 and 5, respectively, the old-line holding portion 10 having a circular hole shape is combined. Also, the new line holding portion 11 is formed.
When the attachment of the intermediate support 1 is completed, the old wire Wa is removed from the insulator fitting G and held by the old wire holding portion 10 of the intermediate support 1. This operation is performed by removing the pressing plate 4 and fitting the old wire Wa into the groove 6, and then reattaching the pressing plate 4.

It is carried out using 0, and it is a mobile wagon 20, 20, ...
While pulling the connecting rope C for connecting the mobile wagons 20, 20, ... While deploying the mobile wagons 20, 20, .. Similarly, the wire rope R is pulled by the self-propelled machine 30 and deployed. In this way, the wire rope R is unfolded while being supported by the mobile money wheel 20 in parallel with the expansion of the mobile wire wheel 20, whereby slack of the wire rope R is prevented. Here, the mobile gold wheel 20 is formed of a traveling portion 21 and a support portion 22 vertically provided from the traveling portion 21, and can travel on the support line Sn and a support line Sa described later by the traveling portion 21. Further, the supporting portion 22 can movably support the extended rope R, the old wire Wa, or the new wire Wn. Also,
As shown in FIG. 4, this movable wheel & pinion 20 has an intermediate support 1
It is more preferable to provide a door 23 that automatically opens when it hits the hanging arm 2 and form a closed space 24 by this door 23 to prevent derailment. When the mobile gold wheels 20, 20, ... Are unfolded, they are positioned and fixed at predetermined intervals. In order to perform this positioning / fixing, as shown in FIG. 3, the connecting rope C is fixed to the support P, and if necessary, each movement is performed by an appropriate braking means provided on the traveling portion 21 of each movable rail 20. The gold wheel 20 is individually fixed to the old line Wa, that is, the support line Sn. Although the figure is simplified and the three columns P and the intermediate support 1 are shown only in one column P, there are actually more columns, and each column has an intermediate column. A support 1 is provided.

より一層作業の合理化を図れる。As described above, the method for replacing the high-voltage line for railway according to the present invention is developed by using the old line for the extension of the new line and the new line for the removal of the old line as the support lines. Because the new line and the old line are removed while being supported by multiple moving wagons, there is no effect on the trolley line and traveling trains due to the looseness of the new line and the old line. Therefore, it is possible to work under better working conditions without being restricted by the workable time zone. Also, since the old wire is used as a support wire for the new wire extension, it can be used for new wire extension. The work for deploying and removing the support line is not required, and the work can be greatly rationalized. Furthermore, the use of the old line and the new line as the support line is performed only by the work of holding the old line and the new line by exchange with the intermediate support. The old line is removed and the new line is extended. To the carried out continuously, also easy to switch to the extended line of the new line from the removal of the old line,
The work can be further streamlined.
