Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for vertically transporting excavated earth, cement, concrete, etc.

Skips are widely used for transporting earth and sand in the vertical direction, but they generate a lot of noise when loading and discharging earth and sand. Work is interrupted during the raising and lowering of the skip, which is an intermittent operation, so it has the disadvantage of being inefficient, especially when the height difference becomes large.

A device has also been developed that pressurizes the material inside the pipe and pushes it up, but the material rubs against the inner surface of the pipe, which tends to cause meshing. As a result, resistance increases, causing wear and noise, and when a highly viscous material such as clay soil is pressurized, frictional resistance increases rapidly, sometimes resulting in inoperability.

The present invention has been made to improve these points, and an object of the present invention is to provide the following conveying device.

<1> A transportation device that generates almost no noise when loading and unloading materials and can be used even in urban areas.

<2> The movement is not intermittent like skipping,
A device that can transport materials continuously and efficiently.

<3> A transportation device that can reduce the area occupied in a shaft to a fraction of that of a skip device, thereby making effective use of the shaft space or reducing the area of the shaft.

<4> A transportation device that does not cause abrasion, noise, or clogging of pipes because there is no sliding contact between the inner surface of the pipe and the material.

<5> Compared to a skip device, a transportation device that can lower the height above the ground of a shaft, and can keep the overall height low by installing a gate-type crane or the like on the top.

<6> A transportation device that can be used from the time shaft excavation begins by sequentially extending the device.

<7> A transportation device that can easily transport even clayey soil.

<8> A transportation device that requires less power to operate than a skip, etc.

Next, an example will be described.

This transportation device is mainly composed of a bucket 2 that moves up and down within a vertical tube 1, and a rotary plate 3 that serves both as a scraper and a door.

<1> Vertical tube The vertical tube 1 is a long pipe in the vertical direction, and has a discharge port 11 at the top and an input port 12 at the bottom side, and has no partitions inside either in the vertical direction or in the transverse direction. In the embodiment, the input port 12 is connected to the hopper 13 by a conveyor 14, but any structure may be used as long as it can input earth and sand from the side of the vertical tube 1.

<2> Lifting bucket cant group Inside the vertical tube 1, there are two sets of bucket cants arranged in parallel in the vertical direction, namely the left bucket cant group 2L and the right bucket cant group 2.
Install R.

Each bucket group consists of a plurality of arc-bottomed buckets 2, and the arc-bottomed buckets 2 are arranged in the vertical direction.
The upper parts of the bucket cart groups 2L and 2R are connected by one chain C, and the chain C is suspended from the upper end of the vertical cylinder 1 via a sprocket _C1 provided. The bucket cart moves up and down by driving this sprocket _C1 , but the left and right bucket cart groups 2L and 2R
Since the weights of the two machines are hooked together, the power required for lifting and lowering is equivalent to the difference in the weight of the soil, making it extremely economical.

In addition, in the above description, a plurality of bucket tots 2 are combined together to form a bucket tot group, and this bucket tot group is divided into 2
An example has been described in which the buckets 2 are arranged facing each other, but if the lifting distance is short, a structure in which one bucket bag 2 is raised and lowered as shown in FIG. 2 may also be adopted.

At this time, as a result of transferring the earth and sand in the middle as described later, there is no need to provide earth and sand discharge ports and sand input ports on both sides, even though it is a hanging well type. The advantage arises that it is possible to carry out a rise of .

On the other hand, the arc-bottomed bucket bag 2 is a container with a bottom plate 23 having an arcuate surface, and this arcuate surface is configured to face the center of the vertical cylinder 1. Therefore, each bucket bag 2 has a shape in which two sides, namely, one side facing inward and the upper side, are open.

<3> Rotating Plate As described above, each arc-bottomed bucket 2 is an arc-shaped container with an open inner side and an upper surface, and a rotating plate 3 is provided at the inner open part of each bucket 2.

This rotating plate 3 is a plate body that also functions as a door and a scraper, and the rotating shaft 3 is located at the central axis of the circular arc surface.
1, and is configured to be rotatable only in the direction of scraping out items inside the bucket toward the inner opening.

A rotation drive source for rotating the rotary plate 3 is provided for each bucket.

As this rotation mechanism, for example, as shown in FIG. 3, a motor reduction gear 37, a sprocket 39, and a chain 40 may be attached to each bucket cart 2, and each bucket cart 2 may be operated independently.

Next, the earth and sand transport process will be explained. (4th to 8th
(1) S-S (Fig. 4) In the embodiment shown in the figure, each bucket group 2L, 2R has 2
It has two buckets, which are connected by connecting materials or chains at intervals of three buckets height 2, and explains the situation in which the earth and sand filled in the lower left bucket _L1 gradually rises. .

In this case, each bucket repeats raising and lowering alternately on the left and right sides in a tsurube-ido style with a stroke of only three frames.

(2) L ₁ → R ₁ (Figure 5) Lower left bucket L ₁ rises 3 frames, lower right bucket R ₁ descends 3 frames, so lower right bucket R ₁
1 frame higher.

If the rotary plate 3 of the lower left bucket L ₁ is rotated, the earth and sand will be transferred to the lower right bucket R ₁ .

(3) L ₂ ← R ₁ (Figure 6) The upper left bucket L ₂ goes down 3 frames, and the lower right bucket R ₁ rises 3 frames, so the upper left bucket L ₂
Lower right Bucket R ₁ becomes one frame higher.

If the rotary plate 3 of the lower right bucket _R1 is rotated, the earth and sand will be transferred to the upper left bucket _L2 .

(4) L ₂ → R ₂ (Figure 7) The left side goes up 3 frames and the right side goes down 3 frames.

Since the upper left bucket L ₂ is one frame higher than the upper right bucket R ₂ , the rotation of the rotary plate 3 moves the earth and sand to the upper right bucket R ₂ .

(5) Ejection (Fig. 8) The left side descends 3 frames, the right side rises 3 frames, and the rotating plate 3
By rotating, earth and sand are discharged from the discharge port 11.

The present invention, as described above, attaches upward-opening buckets to both ends of the chain engaged with the sprocket provided at the top of the outer cylinder, and each bucket has a rotary plate that also serves as a door facing toward the inside of the outer cylinder. The outer cylinder is equipped with a dirt discharge port at the upper stop position of the bucket, and a dirt input port at the lower stop position of the bucket. Therefore, the following effects can be expected.

<1> Since the operation is by raising the bucket and scraping by a rotating plate, it generates almost no noise and can be used in urban areas.

<2> Since the earth and sand and other objects to be transported rise almost continuously, it is extremely efficient compared to intermittent operations such as skips, which require a long waiting time.

<3> As a result of the large amount of work per hour, the space occupied is a fraction of that of a skip device.
Can be done.

<4> Compared to the method of moving inside the tube, the transported object does not come into contact with the inner surface of the outer cylinder, so there is no dirt entrapment, which reduces the phenomenon of sudden load increase and noise generation.
No spillage of moving objects, etc.

<5> Since the objects to be transported do not come into contact with walls, etc. during movement, and scrapers are used to scrape them out, it is possible to handle not only loose objects but also highly viscous soil, oil, tar, etc.

<6> The rotary plate of the bucket doubles as a door and a scraper, so it has a simple structure, is difficult to break down, and can be manufactured and maintained economically.

<7> The ground height of the shaft is lower than that of a skip, and the space above the shaft can be used for a gate-type crane, etc.

<8> Can be used as extraction equipment from the time of shaft excavation.

<9> Since it is a hanging well system, the driving force is only about the difference in the weight of the earth and sand between the two bucket groups, making it extremely economical.

<10> Even highly adhesive soil is forcibly scraped out using a rotating plate, so it does not remain in the bucket and can be transported efficiently.

<11> A drive source that rotates the bucket door/rotating plate was attached to each bucket.

Therefore, there is no need to synchronize the rotational operations of the doors of a plurality of buckets, and each bucket can be operated independently, resulting in a simple structure.
