Next, I will explain the operation〇 The wire catching device 13 is activated prior to the series of operations.

Explain the movement.

(1) When picking up the wire t Since the wire catching device t3 of the trolley 10 is located at a high position above the rail 60, when the wire 9 is caught and traveling, the wire catching device t3 of the trolley 10
ri! As shown in J, the wire 9 hangs down before and after the wire catching device 130. In other words, the wire 9 needs to run at a higher position than the top surface of the rail 60 at the catching place (see Figures 10 and 11). .

When the trolley 10 enters the wire catching place and the wire catching guide rail 27 contacts the shaft 15 through the arm 18, the threaded part 169 rotates, and the left and right catching members 21, 22 opens against springs 25 and 26. Furthermore, when the Torotsu lO runs and the four-ra 19 comes off the wire catching guide rail, the shaft holder 5 is moved downward by the weight of the low-y19 itself, and the shaft holder 5 is moved to the 90 position via the arm 18.
f rotation, and the left and right catching members 21 * 22 are closed via the threaded portions 16 and 171 to bite the wire 9t').

(2) When releasing the wire, as shown in Fig. 12, since the wire 9 hangs down before and after the wire catching device I3 while running as described above, the wire 90 should be placed at the same level as the running surface of the wire 90 and the rail surface t- and then laterally. If you create a wire release field with a wire release guide rail 29 installed at The catching members 21 and 22 are the springs 25
．． Open against 26. Therefore, the wire 9 falls downward and the wire 9 is released.Next, a series of operations will be explained.

(2) Empty armor r10 that has captured the wire 9 and moved up the upward track l releases the wire 9 by the wire release guide rail 3I while traveling from point B to point B.

(2) The trolley 10 with the wire 9 released is accelerated while traveling down the nine slopes from point B to point 0, and passes through the high-altitude side switching point 5.

This high-altitude side switching point) S is able to reach point %D without derailing if TRON WIQ approaches from either direction from point 0 or point H due to the spring 61, but trolley 10 from the direction of point D When it enters, it always moves in the direction of point B.

■ After passing the high-altitude side switching point 5, the trolley IO climbs uphill and stops before reaching point D and starts moving backwards.

■ Retrograde Tron: ff1Ot! The switching point 5 advances towards the pli point and captures the wire 9 while traveling between points. -〇 When the trolley io that has captured the wire 9 reaches the zero point, the apron feeder 58 of the loading device 59 shown in FIGS. 21 and 22 is driven and the earth and sand 63 is loaded.

■ After that, the toy loaded with 63 earth and sand: f+.

travels on the lower p track 2 while pulling the wire 9.

■ Trolley running on down track 2 1 from 1oFiI point
While traveling the point, the wire 9 is released and the vehicle descends freely on the downward trajectory.

The strain relief device 45 has the function of reducing the force exerted by the lower load truck IO on one wire 9 or 9' to below the allowable tension of the wire 9,9', and connecting the loops of adjacent wires 9,9'. It has the following.

, If you do as shown in Part B, the speed of wires 9 and 9'(T4''
: I + OO linear speed) becomes constant over the entire line, and 9p control becomes easier.

That is, by running the wire 90, the second main idler 46
rotates, and this rotation is transmitted to the third type idler 47 via gears 49, 51 and interferes with the running of the wire 9'.

In addition, the 460 rotations of the second type idler drive the generator 53t through the speed increaser 52 and are used to generate electricity. Trap and reach the soil removal site.
Exclude. That is, when the overturning wheel 38 is on the earth removal guide rail 44, the vessel 32 falls to the side using the bin 36 as a fulcrum. At the same time, the opening/closing door 39 opens and the earth and sand in the vessel 32 is discharged.

(2) When the trolley 10 reaches the end point KsP of the discharge location, the vessel 32 returns to its original position, and the trolley 10 further passes the discharge location and releases the wire 9' between point M and point N.

[Phase] After releasing the wire 9', the trolley 10 descends downhill, passes the switching point 6t-, and proceeds in the direction of the 0 point. At this point, the trajectory becomes uphill, and by the time it reaches the 0 point, the trajectory has stopped and started moving backwards.

■ Move the trolley lot that has gone backwards to the upward trajectory IK at switching point r6. The empty trolley 10, which has moved up the upward track IK, falls freely down the downhill slope, catches the shear wire 9' by the wire catching guide rail 30 installed between points 7 and υ, and advances on the upward track 1t.

[Phase]) The wire 10 releases the wire 9' between points V and reaches the tension relief device 45, exits this tension relief device 45, and captures the wire 9 between points X and one point. nothing.

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 1" from a high place Q to a high place Q. The high-altitude side switching point 5, which switches the track to the lower orbit 2, and the low-altitude side switching point 6, which switches the orbit from the lower orbit 2 to the upper IK orbit at the low point R, constitute the entire transport area, and this whole transport section The district is divided into a plurality of sections, a loop-shaped wire 999' is installed in each section so that it can run in a circular manner, and one wire 9 runs between the wires 9#9' in each section while the other wire 9' runs. The upper and lower tracks 1 are connected via a tension relief device 45 that interferes with running.
．． This is characterized in that the trolley 10 running on the second floor is equipped with a wire catching device 13Yr for catching one of the wires 9,9' and releasing the catching.

Therefore, the gravity wire 9.9' of the trolley 10
It is possible to reduce the tension of the wires to less than the allowable tension, and to equalize the speeds of adjacent wires 9g and 9', making it possible to transport earth and sand even in places with large transport distances and large height differences.
