[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention is a continuous vertical transfer device suitable as a device for transferring excavated soil to a high place such as above ground, especially in an underground excavation work site, in particular, a boat type connected at appropriate intervals. The transport container is circulated and rotated in a Z-shaped circulation path that is composed of a lower horizontal path that constitutes the transported object input section, an upper horizontal path that configures the transported object discharge section, and a vertical path that connects both horizontal paths. The present invention relates to a continuous vertical transfer device.

2. Description of the Related Art As shown in FIG. 9, a continuous vertical conveying apparatus of this type has an ascending path from an upper horizontal path portion 1a of a lower horizontal path 1 to a vertical path 2 in a Z-shaped circulation path. Upper horizontal path section 3 of upper horizontal path 3 via section 2a
The route to a is defined as a transport route where the boat-shaped transport containers 4 connected at appropriate intervals move while maintaining a horizontal erect posture, and the lower horizontal route 1 which is the starting position of this transport route is described.
The upper horizontal path section 1a of the upper part is the transported object input section 5, and the container reversing path section from the tip turn section 3b of the upper horizontal path 3 which is the end position to the lower horizontal path section 3c is the transported object discharge section 6. However, in this type of conventional continuous transport apparatus, the transport container 4 is rotated by 180 degrees at the end turn portion 1b of the upper horizontal path 3 to change the posture to the horizontal inverted position, so that the transport container in the transport container is rotated. It was designed to release objects by gravity.

In the case of dry powdery or granular materials such as grains,
The transported object in the transport container 4 is almost completely discharged simply by rotating the transport container 4 by 180 degrees at the end turn portion 1b of the upper horizontal path 3 to change the posture to the horizontal inverted position. In the case of clayey mud with high moisture and high viscosity, such as excavated sediment, it is rare that the carrier 4 is completely discharged simply by inverting the container upside down. There is a high possibility that the residue will remain. When such clay-like muddy earth and sand adheres and remains in the container, the residue in the container moves due to gravity or gravity in the path portion where the empty transfer container 4 moves in the horizontal upside down posture or the vertical posture. It may slide down due to vibration, and may be attached to a drive chain (in the conventional example shown in FIG. 9, the drive chains 7 and 8 that also serve as container attitude control) or a guide rail that circulates the transport container 4, causing a failure, Even if it is not so, it is fully conceivable that finally the sediment deposited in the case containing the container circulation path will cause the same failure.

In the continuous vertical transfer device constructed as described above, the drive toothed wheel 14 is rotationally driven by the motor 16 in a predetermined direction to rotate the drive chains 15a and 15b, whereby each transfer container 4 is moved. However, from the upper horizontal path portion 1a of the lower horizontal path 1 to the ascending path portion 2a of the vertical path 2, the upper horizontal path portion 3a of the upper horizontal path 3, the tip turn portion 3b, the lower horizontal path portion 3c, and the vertical path 2 descending. The Z-shaped circulation path is rotated so as to pass through the path portion 2b, the lower horizontal path portion 1b of the lower horizontal path 1, and the tip turn portion 1c in this order. At this time, the transport container 4 includes the drive chains 15a, 1
5b, it is suspended swingably around horizontal support shafts 23a, 23b. As shown in FIG. 5, in the upper horizontal path portion 1a of the lower horizontal path 1, the container attitude control means 28 is provided. All the guide rollers 19a to 20b are supported by the guide rail 27, and move horizontally while being held in the horizontal erect posture. In the turn section of the vertical path 2 to the rising path section 2a, the guide path moves rearward in the groove-shaped guide rail 26B.

It moves horizontally while being held in an upright position. Thereafter, as shown in FIG. 7, when the transport container 4 moves the transported object discharging portion 6 from the tip turn portion 3b to the lower horizontal path portion 3c, the guide rails 26A and 27 and the container attitude control means are used. Each of the guide rollers 19a to 37 has grooved guide rails 25B and 26B.

The guide rail 27 of the container attitude control means 36 of FIG.

As shown in FIG. 6, the transport container 4 which moves in a horizontal upside down posture has a groove-shaped guide rail 25.
Each of the guide rollers 19a to 20b is sequentially guided by the guide rollers B and 26B, and rotates from the inverted posture to the horizontal erect posture again,
The vehicle enters the descending path portion 2b of the vertical path 2 as it is. The transport container 4 in the descending path portion 2b is
One guide rail 25A, 26A is
By contacting the inside of a to 20b, it moves downward while being maintained in the horizontal erect posture.

From the lower end of the descending path portion 2b to the lower horizontal path 1
The transport container 4 that moves to the lower horizontal path portion 1b is moved by the guide rollers 20a and 20b outside the rear end moving inside the groove-shaped guide rail 26B of the container attitude control means 32.
Lower horizontal path portion 1b while changing to a tilting position of falling forward
After entering the inside and maintaining the tilted posture for a certain distance,
It is switched to the horizontal upright posture again. Thereafter, the transport container 4 is horizontally moved while being held in the horizontal erect posture by the guide rollers 19a to 20b being supported by the guide rail 27 of the container posture control means 29, and subsequently, the groove-shaped guide rails 25B and 26B. Inside each guide roller 19a-20b
Moves, the transport container 4 rotates upwardly on the tip turn portion 1c while maintaining the horizontal erect posture, and enters the original upper horizontal path portion 1a.

Therefore, if excavated earth and sand or the like is fed from the object-to-be-conveyed portion 5 into each of the transport containers 4 that horizontally move by connecting the upper horizontal route portion 1a of the lower horizontal route 1 in a daisy chain, And the like are transported to the tip turn portion 3b of the upper horizontal path 3 by the transport container 4 which moves while maintaining the horizontal upright posture, and the transport container 4 is brought to the vertical posture in the subsequent object discharge part 6. It is switched and further changed to a horizontal upside-down posture, so that it is released by gravity.

Explaining in more detail the phenomenon of discharge of earth and sand, etc., when the transport container 4 moving from the tip turn portion 3b to the lower horizontal path portion 3c is switched to the vertical posture by the container posture control means 37, The earth and sand try to lower to the lower end (front end) side of the transport container 4 which is in a vertical posture due to gravity, but the transport container 4 does not continuously turn over to the horizontal upside-down posture, but keeps its vertical posture. Since it moves over a distance, the soil and the like inside is surely given an opportunity to slide by gravity toward the lower end (front end) side of the transport container 4 in the vertical posture. Moreover, the elastic sheet 38 moves toward the outside of the transport container 4 while being deformed so as to hang down integrally with the earth and sand along with the tendency of the earth and sand to slide, and at the same time, the elastic sheet 38 is separated from the protrusion 40 to cause the protrusion. Since the elastic sheet 38 that has been deformed in a wave shape along the line 40 is in a freely deformable state,
The inner sheet and the like and the elastic sheet 38 which tend to slide downward
Large relative slip occurs between the elastic sheet 3 and the elastic sheet 3.
The sliding resistance of the soil and the like against the ground 8 is greatly reduced, and the soil and the like inside slide down vigorously with inertia.

While the transport container 4 moves while maintaining its vertical posture, most of the earth and sand inside will slide off from the transport container 4, but some of it will be deformed and remain in the container. The sheet remains in the state of being wound around the sheet 38 or attached to the elastic sheet 38. However, next, the transport container 4 rotates to the horizontal upside down posture, and at this time, the elastic sheet 38 is deformed so as to hang completely outside the container due to gravity as shown in FIG. Due to the inertia applied to the adhered earth and sand and the relative slippage due to the deformation of the elastic sheet 38, almost all of the earth and sand adhering and remaining on the elastic sheet 38 is easily separated from the elastic sheet 38 and falls. Become.

After that, the transport container 4 in the horizontal upside-down posture passes over the scraper 41. At this time, the elastic sheet 38 hanging in an arc shape from the container deforms and rides over the scraper 41 while sliding on the scraper 41. It will be. Therefore, the residue attached to the elastic sheet 38 is
It is completely scraped off by the scraper 41.

The emptied transport container 4 in the upside down position descends with the descending path portion 2b of the vertical path 2 returned to the horizontal erecting position, and the lower horizontal path section 1 of the lower horizontal path 1
b. At this time, since each of the transport containers 4 temporarily changes to a tilted posture, if necessary, the cleaning means 3 is moved toward the inside of each of the transport containers 4 which changes from a horizontal erect posture to a tilted posture.
By injecting cleaning water from the nozzle 33 of No. 4, it is possible to wash off the earth and sand adhering and remaining on the inner surface of the transport container 4 including the surface of the elastic sheet 38. The cleaning water does not accumulate in the transport container 4 because the cleaning water moves while maintaining the tilting posture for a while.

Note that the lower horizontal path section 1 of the lower horizontal path 1
b and the descending path portion 2b of the vertical path 2, the transport container 4 is in an inverted posture parallel to the moving direction (the moving posture of the transport container 4 in the latter half of the lower horizontal path portion 3c in the upper horizontal path 3). You may comprise so that it may move. In this case, if the cleaning means 34 is provided side by side, for example, the cleaning water may be sprayed toward the inner surface of the transport container 4 that descends the descending path portion 2b of the vertical path 2. Further, depending on the property of the material to be transported such as earth and sand, a conventional configuration in which the transport container 4 is inverted to the horizontal upside down posture at the tip turn portion 3b of the upper horizontal path 3 can also be adopted.

[0030]

According to the continuous vertical transfer device of the present invention which can be implemented and used as described above, when the elastic sheet overlapping the inner bottom surface of the transfer container is in the horizontal upside down posture. It is stretched so that it hangs away from the inner bottom surface of the container due to gravity, so the transfer container is reversed at the container reversal path part (transported material discharge part) from the tip turn part of the upper horizontal path to the lower horizontal path part. At this time, the elastic sheet is deformed so as to hang down apart from the inner bottom surface of the container due to gravity together with the earth and sand which are about to fall.

That is, even if the transport container is turned upside down 180 degrees at the end turn portion of the upper horizontal path, the adhesion between the elastic sheet and the container inner bottom surface is not affected by the elastic sheet and the covered sheet. It is small compared to the adhesiveness with the transported material such as earth and sand.Therefore, the earth and sand that is in direct contact with the inner bottom surface of the transport container that has been turned upside down will adhere to the inner bottom surface of the container. Even if gravity makes it difficult to separate and drop by gravity alone, the elastic sheet easily separates from the inner bottom surface of the container, which promotes the falling motion of earth and sand in the container.

Moreover, since the elastic sheet hanging from the inner bottom surface of the container is largely deformed from the shape when it overlaps with the inner bottom surface of the container, the elastic sheet and the earth and sand contacting the elastic sheet are deformed due to the sagging deformation of the elastic sheet. Relative slippage occurs between the two, and the two can be easily separated.
Furthermore, the inertial force acting on the earth and sand that tends to fall out of the container with the sagging of the elastic sheet effectively acts as a separating force of the earth and sand from the elastic sheet when the sagging deformation of the elastic sheet is completed. As
Even when handling conveyed objects that tend to adhere to and remain on the inner surface of the conveyed container, such as clayey mud with high moisture content and high viscosity, the conveyed container that is turned over at the conveyed object discharge section It can be released reliably.

Further, according to the structure of the present invention, a scraper is provided on the lower side of the object discharge portion for overcoming the elastic sheet hanging from the horizontally inverted container while sliding over and deforming the elastic sheet. Even if there is a residue attached to the sheet, it can be finally scraped off and cleaned with the scraper. In other words, due to the combination of the elastic sheet and the scraper that promotes the discharge of the transported object in the container, the structure is complicated, such as the scraper that automatically enters the moving transport container to clean the inner surface. A scraper that requires high accuracy is no longer required, and the extremely simple means of arranging a rod-shaped or plate-shaped fixed scraper under the passage path of the transfer container ensures scraping and cleaning of the residue inside the container. It has become possible to do it. Of course, since the scraper is in sliding contact with the elastic sheet that is hanging down, even if the scraper placement accuracy is low, there is no possibility that a pressing force above a certain level will act between them, and the service life is long.

For the above reasons, in the path portion where the empty transport container moves in the horizontal upside down posture or the vertical posture,
Eliminates or significantly reduces failures caused by the constant residue sliding in the container due to gravity and vibration, and requires frequent maintenance work including cleaning the inside of the equipment to avoid such a situation. Also disappears.
