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 a vertical direction, but they produce a lot of noise when loading and discharging earth and sand.

■While the skip is going up and down, it is an intermittent operation that interrupts the work, so it is inefficient especially if the difference in height is large. ■Twiya rope for hoisting is easy to wear and break, requiring time and skill to replace the rope, and if it is cut, the skip will skip. The disadvantage is that there is a risk of falling.

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 jamming.

As a result, resistance increases, causing wear and noise, and when a highly viscous material such as clay soil is pressurized, the wear resistance increases rapidly and may become inoperable.

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

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

A device that can transport materials continuously and efficiently without intermittent operation like a Φskip.

A transport device that can reduce the area occupied within a shaft by several minutes of IVC compared to a Φskip device, thereby making effective use of the shaft space or reducing the shaft area.

ΦA transportation device that does not use wire ropes, so there is no need for troublesome wire hanging, and there is no risk of accidents due to cutting.

A conveying device that does not cause sliding contact between the inner surface of the Φ pipe and the material, causing no wear, noise, or clogging of the pipe.

■Compared to skip equipment, the ground height of the shaft can be lowered,
A transportation device that can keep the overall height low by installing a gate-type crane, etc. on the top.

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

◇A transportation device that can easily transport even clayey soil.

■Transportation device that requires less power to operate compared to skips, etc.

Next, an example will be described.

This transport device is mainly composed of a packet 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 vertically long pipe with a discharge port 11 at the top.
, an input port 12 is provided at the lower side, and no partitions are provided inside either the vertical direction or the transverse direction.

In the embodiment, the input port 12 has a structure in which it is connected to a hopper 13 by a screw conveyor 14, but any structure may be used as long as earth and sand can be input from the side of the vertical tube 1.

<2> Elevating Packet Groups Two sets of packet groups, namely a left packet group 2L and a right packet group 2R, are installed in the vertical tube 1 in parallel in the vertical direction.

Each packet group consists of a plurality of pan bottom packets 2, and the pan bottom packets 2 are arranged in the vertical direction, and the pan bottom packets 2 are connected by a vertical connecting member 21 so that each packet group can move up and down as one unit. Configure.

The left packet group 2L is connected to the left lifting drive source 22L, and the right packet group 2R is connected to the right lifting driving source 22R.

Examples of the elevating drive sources 22L and 22R include a system in which a hydraulic cylinder is provided at the bottom of the vertical tube 1 to lift it up, as shown in FIG. 1, and a system in which a hydraulic cylinder is provided at the top to lift it up.

In addition, as shown in FIG. 2, two packet groups 2L and 2R
When the upper part of the machine is connected with one chain C and the chain C is suspended via the sprocket C1 installed at the upper end of the vertical tube 1, the weight of the left and right packet groups 2L and 2R is balanced, and the power required for raising and lowering is equal to the weight of the machine. It is extremely economical as the difference is only small.

Further, it is also possible to adopt a method in which a vertical rank is vertically attached to the vertical tube 1 side and engages with a binion installed in the packet group to raise and lower the packet group.

On the other hand, the dish bottom packet 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 packet 2 has a shape in which two sides are open: the mutually inwardly facing side and the upper side.

Note that the above example has been explained in which a plurality of packets 2 are combined together to form a packet group, and two sets of these packet groups are provided facing each other, but if the lifting distance is short, one packet 2 is moved up and down. structure can also be adopted.

Also at this time, since a rotary plate 3 which also serves as a door, which will be described later, is provided on one side of the packet 2 on the bottom of the dish, the earth and sand inside the packet 2 can be scooped out reliably, quickly, and noiselessly.

3> Rotating plate As described above, each temporary-fitting packet 2 is an arc-shaped container with an open inner side and an upper surface, and a rotating plate 3 is provided at the open inner side of each packet 2.

This rotary plate 3 is a plate that functions as both a door and a scraper, and has a rotary shaft 31 located at the central axis of the circular arc surface, and can rotate only in the direction of scraping out the contents of the packet toward the inner opening. Configure.

A rotation mechanism is provided so that all rotary plates 3 rotate simultaneously for each packet group.

As this rotating mechanism, for example, as shown in FIGS. 1 and 3, the crank arms 32 of all the rotary plates 3 are connected by one shaft 33.

The shaft 33 and the crank arm 32 are rotatable, and the crank arm 32 is fixed to the rotating shaft 31 of the rotating plate 3. By raising and lowering the crank arm 33 once, the rotating shaft 31 rotates once. I will do it.

In this case, if the shaft 33 is only provided on one side of the rotating shaft 31, it will stop moving or return at the vertical dead center, but if the shaft 33 is provided on both sides of the rotating shaft 310 and the angle of the left and right crank arms 32 is If they are made different, the problem of dead center will not occur.

Furthermore, a rotating plate cylinder 34 is provided at the lower end of the shaft 33.

This cylinder 34 moves up and down together with the second group of temporarily fitted packets, and after stopping the second group of packets at the raised position, it expands and contracts once and rotates the rotary plate 3 once.

Furthermore, instead of moving the crank arm 32 up and down with the shaft 33, it is also possible to rotate the rotary plate 3 in accordance with the rise and fall of the packet 2.

That is, as shown in FIG. 4, a pin 35 is provided protruding from a position different from the rotating shaft 31 of the rotary plate 3, and this pin 35 is engaged with the guide groove 36.

The guide groove 36 is provided vertically, but if the guide groove 36 is bent inward only at the position where you want the rotary plate 3 to rotate, the rotary plate 3
will rotate once as packet 2 rises.

Further, as shown in FIG. 5, a motor reducer 37 is attached to only one packet 2 of a group of packets, and the rotation of this motor 37 is changed to the vertical movement of the shaft 33 via a link 38. A structure in which the crank arm 32 of each packet 2 is pivotally supported on the shaft 33 is also possible.

Furthermore, if the number of packets is small and there is no problem even if there is some deviation in the rotation of the scraper, a motor reducer 37, sprocket 39, and chino 40 are attached to each packet 2 as shown in FIG. Sometimes a method is adopted in which each of the two units is operated independently.

Next, the earth and sand transport process will be explained.

(Figures 7 to 14) (1) (Stop-Stop) In the example of the state diagram, each packet group 2L, 2R is connected by a connecting member 21 with an interval of 3 heights of packets 2, at the bottom left. A state in which the earth and sand filling the packet L1 gradually rises will be explained.

(2) (Rising - Stopping) State Lower left packet L1 rises by 3 frames, lower right packet R1 stops.

The lower left packet L1 rises to 1 from the lower right packet R1.
Since the frame becomes higher, if the rotary plate 3 of the lower left packet L1 is rotated, the earth and sand will be transferred to the lower right packet R0.

(3) (Down-Stop) state Lower left packet L1 goes down 3 frames, lower right packet R1 stops, and (4) (Stop-Up) state Lower left packet L1 stops, Lower right packet R1 goes up 3 frames.

Since the lower right packet R1 is one frame higher than the lower left packet L1, if the rotary plate 3 of the lower right packet R1 is rotated, the earth and sand will be transferred to the upper left packet L2.

(Event (stop-down) state Stop on the left, descend 3 frames on the right.

(6) (rise-stop) state The left one goes up 3 frames, the right one stops.

Since the existing packet L2 is one frame higher than the upper right packet R2, the rotation of the rotary plate 3 moves the earth and sand to the upper right bucket X/R2.

(7) (Down-stop) state The left one goes down 3 frames, the right one stops.

(8) (Stop-Rise) status The left one stops, the right one goes up 3 frames.

The earth and sand moves from the upper right packet R2 to the upper left packet L3.

(9) In the same way, by repeating the cycle of (ascend-stop) state, (descend-stop) state, (stop-ascend) state, (stop-descend) state, the earth and sand will move to the right and left. The soil rises and is finally discharged from the discharge port 11.

The diagram above shows the movement of soil in an easy-to-understand manner.In reality, the left and right sides of the packet group simultaneously move in opposite directions, improving work efficiency and reducing power consumption.

Next, a method for expanding the vertical tube 1 will be explained.

(1) A method in which the vertical stroke is constant (FIG. 15) This is a method in which the vertical interval t between packets 2 and 2 is not changed.

When the excavation has progressed by a distance corresponding to the length t of the connecting member 21, the newly installed vertical tube 1' is connected above or below the old vertical tube 1, and a new packet z is also installed via the newly installed connecting member 21'.

In this system, the lifting stroke of the packet 2 is always constant, and even if the length of the vertical cylinder 1 increases, the carrying capacity does not change.

(2) Method in which the number of packets is constant (FIG. 16) This is a method in which the interval t between the upper and lower packets 2 is changed as the excavation progresses.

Since the number of packets does not increase, the carrying capacity decreases as the excavation length increases.

As described above, the present invention arranges two sets of packets that move up and down externally in close proximity to each other, and each packet has a rotary plate that also serves as a door to scrape out the contents toward the inside of the outer cylinder. This is a transportation device provided.

Therefore, the following effects can be expected.

4) Since the operation is by raising the packet and scraping it out by a rotating plate, it generates almost no noise and there is no problem even when working in a city.

Since the earth and sand and other objects to be transported rise almost continuously, it is much more efficient than an intermittent operation with a long waiting time, such as a skip.

As a result of the large amount of work per 8 hours, the space occupied by the skimp device can be reduced to a fraction of that of the skimp device.

■Compared to the method of moving objects inside a tube, the objects to be transported do not come into contact with the inner surface of the outer cylinder, so there is no encroachment of soil, and there is no phenomenon of sudden load increase, generation of noise, or falling objects.

■It is possible to handle not only loose materials but also highly viscous soil, oil, tar, etc. because the transported objects do not come into contact with walls, etc. during movement, and scrapers are used to scrape them out.

■The rotary plate of the packet serves both as a door and a scraper, so the structure is simple, hard to break down, and economical to operate and maintain.

(g) The system in which the rotary plates of each packet group are operated by a single drive unit eliminates operational errors of each rotary plate, has a simple structure, occupies a small space, and is efficient.

■When the operation of the drive unit at one location on the rotating plate is transmitted to the rotating plate with a phase shift, there is no dead center, the rotational movement is smooth, and no noise is generated.

■The height above ground of the shaft is lower than that of a skip, etc., and the upper space of 3 can be used for an intermediate crane, etc.

<10> It can be used as a sloping equipment from the time of shaft excavation.

庺1〉If one type of elevator is used, the driving force per unit is equal to the difference in the weight of the earth and sand between the two packet groups, which is extremely economical.

42> Even highly adhesive soil is forcibly scraped out by the rotating plate, so it does not remain in the packet and can be transported efficiently.
