Abstract

PURPOSE:To improve the working properties of a system in which upward empty trucks and downward loaded trucks are circulated on a looped track, by enabling the endless movement of the trucks even if there is no earth and sand loaded on the downward trucks at the beginning of the operation of the system. CONSTITUTION:In a system, a plurality of trucks 3 are endlessly connected to one another through couplers 4 and circulated on a looped track consisting of a downward line 2a and an upward line (not shown in the drawing). To construct a brake mechanism A at a part of the downward line 2a, a chain 50 which is sequentially engaged with a first, a second, a third and a fourth idlers 401-404 and a sprocket 41 is provided with claws 80 which are located at prescribed intervals and can be engaged with the pins 90 of the trucks 3. The sprocket 41 is connected through a chain 65 to an accelerating mechanism 66, which is driven by a motor 70 through a chain 69. As a result, the power driving of the trucks 3 at the beginning of operation is enabled. When the downward moving force of the trucks 3 has become high, the motor 70 is stopped.

Description

[Detailed Description of the Invention] This invention relates to a method of operating the gravity type continuous transportation system.@ The gravity type continuous transportation system has four unloaded trucks moving up a loop-shaped track and four loaded trucks running down a loop-shaped track. This is a system for transporting soil. In other words, it is a system that transports the earth and sand by moving the loaded earth and sand using gravity.Problems with this platform When operating for the first time First, it cannot move without power, so it is necessary to load earth and sand onto the rick by some method. The present invention was made in view of the above points, and the purpose is to: During the first operation, the descending side trolley 3 is not loaded with earth and sand.It is now possible to run the endless trolley even on one occasion, and there is no need to load earth and sand onto the descending side cart 3 in some way as in the past. An object of the present invention is to provide a method of operating a gravity continuous transportation system that can efficiently carry out the following.The present invention will be described in detail below with reference to the drawings. A track 2 is installed, forming a downward track 2 m and an upward moving track 2 h, and on the endless track 2 is an endless bogie in which unit bogies 3 of Cape Totsuko are connected in an endless manner via a connecting member 4. 5 is provided so that it can run freely. A Hola Puff equipped with a stock pile 6 is provided at the bent portion 2' on the high side of the endless track 2, so that earth and sand can be dropped and loaded onto the unit truck 3. This constitutes the earth and sand loading mechanism 8 ◎Also, the lower bent portion 2 of the endless track 2
A guide rail 9 is provided which is curved upward along '.

As shown in FIG. 2, the unit truck 3 has a structure in which a vessel 12 is swingably attached to a traveling body II equipped with wheels IO with a pin I3 in a direction perpendicular to the traveling direction.
26ct-2 Auxiliary wheel 1-4 in contact with the guide rail 9
1115 is attached to the door 12 so that it can be opened and closed freely by a bin 16, and the door 15 and the connecting rod 17 supported on the traveling body 11 so as to be swingable and movable are connected via a link mechanism 18. When the auxiliary wheel 14 rides on the guide rail 9, the vessel 12 is tilted and the door 15 is opened.

Then, the earth and sand in the vessel 12 is discharged and loaded onto the purge ship 19.

As shown in FIG. 3, a tension relief device is shown, which is installed across the down track 26 and up track 2h, and connects the braking mechanism A provided on the down track IK and the drive mechanism B provided on the up track 2k as shown in C, the loading unit truck 3 running on the down track 2G is braked, and the braking force is transmitted via the connecting shaft C to the empty loading unit truck 3 on the up track 2b.

On the other hand, the pair of unit bogies 3 and 3 are connected via a coupler 4 as shown in Figure #I4, but since the coupler 4 has play, for example, in Figure 3, the brake is not applied on the downward track 2G. As a result of receiving the braking force from the mechanism 1, the unit truck 3 which is running at a higher place (Im3 Figure A) is lowered by the force of gravity, so the play in the coupler 4 is closed and its length becomes As. %Also, like the unit bogie 3tJ running at a location lower than the braking mechanism A (3rd diagram), the luster of the coupler 4 deteriorates due to gravity.

The first guide rail is held in a prominently protruding position.0 As shown in Figure 15, the drive mechanism Bfd is approximately the same as the braking mechanism l, and the generator flow is not tough Qc. Also, the inclined guide surface 72'G of the second guide rail 2 is provided on the entry side of the unit truck 3, and the third. The only difference is that the fourth idlers 40m and 40m and the sprockets 41 are installed upside down and the % chain 50' rolls in the opposite direction, so the same parts have the same reference numerals. If you add "'" to indicate that they are the same, the explanation will be omitted.The sprocket shaft 59' of the drive mechanism B and the sprocket shaft 59 of the braking mechanism A are connected by a coupling 10G as shown in Fig. 16. It is connected via.

5. The chain 50 is rotated via a transmission sprocket 64, and the endless cart 5 is driven via a claw member 80. In this case, the vehicle speed of the endless trolley 5 is the vehicle speed during transportation.

The position is appropriate.

The earth and sand are sequentially loaded onto the unit truck 3 by the earth and sand loading mechanism 8.
The power consumption of the motor 70C gradually decreases, so control the motor output with a chirotsuba etc. while monitoring the vehicle speed of the endless bogie 5. When the power consumption of the motor 70C becomes zero, turn off the power to the motor OC and start generating power. Turn on the circuit for machine 70. After that, earth and sand transport will begin without power.

Then, the lowering track 26 and the track 35 of the braking mechanism I are continuous, and the one load position truck 3 travels from the lowering track 2G to the track 351 of the braking mechanism A. When reaching this point, the first bottle 90s comes into contact with one side 84 of the claw member 80 and rolls on the chain 50.

From this point, the sprocket 41 rotates once and is transmitted to the sprocket nut shaft 59' of the drive mechanism B via the rotation control wheel 59% coupling 100, so the chain 50' is rolled and the pawl member 80 ' and via the bin 90) side 2
◎ Therefore, the downward side 24! A part of the downward energy (velocity) of the loading unit truck 3 at

Also, ill, second and third pins 90 turtles, 90 dews, 90 ■
The pitch of the pitch and the pitch of each claw member 80 are shown in FIG. 17(a).
As shown, when the first bottle 90 contacts one claw member 80, the other claw member 80 and the second and third pins 90m = 9

0 and the gap S, <S, above the coupler play t) is 13 pins 90. The gap Ss (St is - of the coupler play t) between the coupler 4 and the claw member 80 is narrower.
The rattle is closed.

When reaching the end of M, the first pin 90 of the following unit truck 3
The backlash of the coupler 4 where I comes into contact with the claw member 80 is closed.

Then, as shown in Figure 1) (e), the claw member 80 moves to the inclined guide surface 2' G K li! -#, the movable plate 83 of the claw member 80 is rotated clockwise about the horizontal axis 82 and the p-ra 84 moves together with the first pin 901, so that the leading unit truck 3 and the following unit truck 3 When Fi is separated by the sand, the gap S is separated by 12 pins 90.
- comes into contact with the claw member 80. Therefore, the connection Ii4 is opened by the play It<that is, the gap S).

Then, as shown in FIG. 17C), the claw member 80 in contact with the first and second pins 90m reaches the inclined guide surface 72'-.Similarly to the above, the leading unit truck 3 and the following unit truck 3 are separated. Kotok na sho, the difference between the above-mentioned − interval S and the gap S1 C5*

For this reason, the play of the coupler is 11j (tsho, gap S,)
Only open.

And the third pin as shown in Figure 17-)? When the claw member 80 in contact with Oa reaches the inclined guide surface 2'aK, the leading unit truck 3 and the following unit truck 3 are separated, and the play in the connection I14 is further opened i, passing through the inclined guide surface 2'aK and passing through the inclined guide surface 2'aK. When the third bottle 9-' and the claw material 80 are separated, the play in the coupler 4 becomes completely open.
i to the chain 50 while the chain 5.0 tube is rolling
The running force moves by t.

From this, when the play L of the Ks coupler 4 passes through the braking mechanism l, it becomes ttco, Lt, t, t in sequence.
゜No sudden change from closed state to open state.
Therefore, a large impact force is applied to one coupler 4 and the other coupler 4
Don't damage the drive mechanism BK. Since the chain 50' is reversed and the claw member 80' moves from the inclined guide 1t72'g to the horizontal guide 1i721, the first pin 90i
When the K claw member 80 comes into contact, it pushes up the preceding unit 6 wheel 3, closes the play in the connection I14, and then closes the second degree bin 9C.
bK claw member 80 contacts and pushes up to close the play in connection I #4, and #13 bottle 90 contacts and pushes up to close the play in connector 4. The empty cargo unit truck 3 and the chain 50' are 11L.
During the pushing up, the empty unit truck 3 moves backward by -t with respect to the chain SO', so the looseness of the connection I14 is caused by -t, -t, t on the track side 3. Avoid applying strong impact force.

In addition, since the first braking mechanism/1IIC is equipped with a generator 70 connected to the brake mechanism 41, it is possible to generate electricity using only one lower gear. ``Furthermore, when stopping the 1-meter floating trolley 5, the sprocket shaft 5g#59' can be braked and stopped by the disc brakes 63 and 63' provided with the braking mechanism l and the drive mechanism BIIc. As described above, the endless bogie 5, which is freely movable on the endless track 2 installed at an inclination, is first driven by the motor Oc, and the unit bogies 3 constituting the endless bogie 5 are sequentially filled with earth and sand. Since the lowering force of the unit truck 3 that is loaded and lowered gradually becomes so hot that the power consumption of the motor 7oe becomes zero, the endless truck 5 is run without power. It is now possible to run the endless cart 5 even when loading earth and sand onto the cart 3 on the lower side, and there is no need to load earth and sand into the cart 3 on the descending side by some method as in the past, making operation more efficient. It can be carried out.
