Next, the operation will be explained.

Prior to the series of operations, the operation of the wire catching device 13 will be explained.

(1) When catching the wire The wire catching device 13 of the trolley 10 is located at a higher position than the top surface of the rail 60, so when the trolley 10 runs while catching the wire 9, the wire 9 hangs in front and behind the wire catching device 13 as shown in Fig. 9. Go down. In other words, the wire 9 needs to run at a higher position than the top surface of the rail 60 at the wire catching location (first
(See Figures 0 and 11).

When the trolley 10 enters the wire catching place and the roller 19 comes into contact with the wire catching guide rail 27, the shaft 15 rotates via the arm 18, the threaded parts 16 and 17 rotate, and the left and right catching members 21 and 22 are released by the spring. Open against 25 and 26. When the trolley 10 further travels and the roller 19 comes off the wire catching guide rail, the roller 19 descends due to its own weight, the shaft 15 rotates 90 degrees via the arm 18, and the shaft 15 rotates through the threaded portions 16 and 17 to the left and right sides. Capture members 21, 22 close and grip wire 9.

(2) When releasing the wire, since the wire 9 hangs down before and after the wire catching device 13 while running as described above, the running surface of the wire 9 and the rail surface should be at the same level as shown in FIG. If you create a wire release field with a wire release guide rail 29 installed, Trotsko 10
is running, the shaft 15 is rotated by the wire release guide rail 29 via the roller 19 and the arm 18, and the left and right catching members 21,
22 opens against springs 25 and 26. Therefore, the wire 9 falls down and the wire 9 is released.

Next, a series of operations will be explained.

An empty trolley 10 which has captured the wire 9 and ascended the upward track 1 releases the wire 9 by the wire release guide rail 31 while traveling from point A to point B.

The trolley 10 with the wire 9 released is accelerated while traveling downhill from point B to point C and passes through the high-altitude side switching point 5.

This high-altitude side switching point S can reach point D without derailing even if the trolley 10 approaches from either point C or H due to the spring 61, but the trolley 10 from the direction of point D
When it enters, it always moves in the direction of point H.

Trotko 1 that passed the high-altitude side switching point 5
0 climbs uphill, stops before reaching point D, and starts moving backwards.

The trolley 10, which has moved backward, moves toward point H by the switching point 5 and captures the wire 9 while traveling between points E and F.

When the trolley 10 that has captured the wire 9 reaches point G, the apron feeder 58 of the loading device 59 shown in FIGS. 21 and 22 is driven to load earth and sand 63 onto the trolley 10.

Thereafter, the trolley 10 loaded with earth and sand 63 runs on the downward track 2 while pulling the wire 9.

The trolley 10 traveling on the downward trajectory 2 releases the wire 9 while traveling from point I to point J and freely descends on the downward trajectory 2.

The strain relief device 45 has the function of reducing the force exerted by the downward loading trolley 10 on one wire 9 or 9' to below the allowable tension of the wires 9, 9', and connecting the loops of adjacent wires 9, 9'. It is something.

In this way, the speed of the wires 9, 9' (vehicle speed of the trolley 10) becomes constant over the entire line and control becomes easy.

That is, the second main idler 46 rotates as the wire 9 runs, and this rotation is caused by the gears 49 and 5.
1 to the third type idler 47 and interferes with the running of the wire 9'.

Also, the rotation of the second type idler 46 is controlled by the speed increaser 52.
The power generator 53 is driven through the power generator 53 to generate electricity.

The trolley 10 that has passed through the tension relaxation device 45 captures the wire 9' between points K and L, reaches the soil removal site, and discharges the soil. That is, the overturning wheel 38 rides on the earth discharge guide rail 44, and the vessel 32 falls to the side using the pin 36 as a fulcrum, and at the same time, the opening/closing door 39 opens and the earth and sand in the vessel 32 is discharged.

When the trolley 10 reaches the end of the soil removal area, the Bethel 32 returns to its original position, and then the trolley 10 returns to its original position.
0 passes the soil unloading place, and the wire 9' is released between the M point and the N point.

After releasing the wire 9', the trolley 10 descends downhill, passes the switching point 6, and moves toward point O. At this point, the trajectory becomes uphill, and the trolley 10 stops and starts moving backwards by the time it reaches point O.

The trolley 10, which has moved backward, moves to the upward trajectory 1 at the switching point 6. The empty trolley 10, which has moved to the upward trajectory 1, freely descends downhill and reaches point T and U.
Wire catching guide rail 3 installed between points
0, it catches the wire 9' and travels on the upward trajectory 1.

The trolley 10 releases the wire 9' between point V and point W to reach the tension relief device 45,
The wire 9 is captured between the X point and the Y point after exiting the tension relieving device 45.

The present invention has been described in detail above, and includes an upward trajectory 1 from a low place R to a high place Q, a downward trajectory 2 from a high place Q to a low place R, and a downward trajectory 2 from an upward trajectory 1 to a high place Q. The high-altitude side switching point 5, which switches the track to Loop-shaped wires 9 and 9' are installed in each section so that they can run in a circular manner, and the running of one wire 9 interferes with the running of the other wire 9' between the wires 9 and 9' in each section. communicate via a strain relief device 45;
The trolley 10 traveling on the upper and lower tracks 1 and 2 is equipped with a wire catching device 13 that captures the wires 9 and 9' and releases the capture.

Therefore, the tension of the wires 9, 9' due to the gravity of the trolley 10 can be made lower than the allowable tension, and the speeds of the adjacent wires 9, 9' can be made equal. However, it becomes possible to transport soil.
