Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gravity transport method for transporting earth and sand.

Is it possible to circulate earth and sand by gravity using continuous trolleys? The present applicant has previously proposed a gravity-type transportation system for transportation.

However, the number of trolleys is determined by the transport distance and the total length of the trolley.

Therefore, although it is suitable for transporting large amounts of soil, it is not necessarily suitable for transporting medium or small amounts of soil.

The present invention has been made in view of the above circumstances, and its purpose is to make it easier to load earth and sand onto trolleys at loading yards, and to reduce the gaps between trolleys so that spill guards can be easily installed. The aim is to make it possible to load all the earth and sand onto a trolley simply by installing the earth and sand without dropping it onto the tracks.

Hereinafter, the present invention will be explained with reference to the drawings.

In addition, the tension relaxation device 7 is (length of the main chain 49)
> (length of the trolley 30 x 2 + length of the coupler 20), otherwise the meshing of the claws 50 of the trolley 30 and the main chain 49 will be incomplete.

The entire loading device 64 in the loading area 5 is shown in FIGS. 16 and 17.

The loading device 64Vi is equipped with four sprockets 66, 67, 68, and 69 that are rotatably supported on the base frame 65. A chain 70 is hung between the sprockets 66 to 69, and the chain 70 is connected at a predetermined interval. Multiple spill guards 71
is the installation.

The spill guard 71 is equipped with a roof-shaped card body 72, a guide 73 is attached to the guard body 72 to prevent dirt from collapsing from side to side, and the guard body 72 is equipped with all wheels 74.

Upper and lower guide rails 75 and 76 are attached to the base frame 65, and a sprocket 66 is used for driving and is rotated by a motor 77.

In the drawing, 78 is a hopper, and 79 is an apron feeder.

Next, the operation will be explained.

In the vicinity of the loading area 5, as shown in FIG.
0 should just travel to position B. This is the case due to the above-mentioned topography. Therefore, the loading area 5 is a slack section of the coupler 20,
The trolley speed is slow, which makes loading easier, and the distance between the trolleys can be reduced.

Then, the υ sprocket 66 is driven by the motor 77, the chain 70 is run, and the spill guard 71 is run on the lower rail 76, so that the spill guard 71 closes the gap 80 between the trolleys 30 from above. In this state, hopper 7
The earth and sand in 8 is sent by an apron feeder 79 and transported to a trolley.

Load on 30.

In this way, earth and sand are continuously loaded into the trolley 30.
Then, the group of trolleys 30 travels on the downward track 2 and enters the tension relief device 7.

If the strain relief device 7 is simply installed on a slope, as shown in FIG.
becomes loose (because the apparent distance between the trolleys 30 becomes shorter), and the claws 50 of the downward track side tension relief part and the claws 18 of the trolley 30 no longer engage with each other.

However, as mentioned above, the input alloy 11 of the tension relief device 7]
As shown in Fig. 4, the downward track 2 is V-shaped so that the trolley 3 enters the tension relief device 7.
0. Since the downward force of the trolley 302 + 303 + 304 is applied to the coupler 20 and the coupler 20 is always tensioned, the trolley 3
The pawl 18 of 0 and the pawl 50 of the descending track side tension relief part 44 mesh well.

When the claw 18 of the trolley 30 and the claw 50 of the descending track side tension relief section 44 engage, power is applied to the shaft 62 via the main chain 49, main sprocket 47, and transmission sprocket 53, and the gears 63° 63', 1fl'll. 52"'
The tension is transmitted to the tension relaxation section 45 on the upward track side through the rotation of the main chain 49', and the trolley 30 on the upward track side 1 is driven.

Further, a portion of the power that has entered the main sprocket 47 enters the power generator 53 and excess energy is absorbed. In this way, the overall trolley vehicle speed is controlled.

When the trolley 30 leaves the tension relief device 7, the eave side wheels 38 run onto the earth removal rail 70 at the earth removal site 6, and the vessel 3
2 falls to the side 1, the opening/closing door 39 opens, and the earth and sand are discharged.

The trolley 30, with all 6 of the discarded earth prostitutes, enters the upward trajectory 1.

The present invention has been described in detail above, and the up track 1 and the down track 2 are installed in a loop from a high point Q to a low point R, and adjacent trolleys 30 are connected endlessly by a coupler 20 made of a chain. In a system in which 30 groups of trolleys circulate on the orbit by gravity, the high WT of the descending orbit 1
Normal running section 8 on the entrance side of the loading area 5 provided on the Q side
The vehicle speed of the trolleys 30 is reduced by making the downhill track 1 of the loading yard 5 have a downward slope, and by giving the descending track 2 of the normal running section 9 on the exit side of the loading yard 5 an upward slope to reduce the gap between the trolleys 30 at the loading yard 5. This makes it easier to load earth and sand onto the trolleys 30 at the loading dock 5, and since the gaps between the trolleys 30 are small, earth and sand can be dropped onto the track simply by installing a simple spill guard. Earth and sand can be loaded onto the trolley 30 without any problems.
