【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a schematic explanatory view of a transporting device for transporting a segment.
As shown in FIG. 1, the transport device 2 includes a rail 4 and a transport device 6, and transports the segment 8 from the ground 10 through the vertical shaft 12 to the face side of the underground shaft 14.
Two rails 4 are provided in parallel to the horizontal direction at a predetermined interval. These rails 4 are arranged from the ground 10 through the shaft 12 to the inside of the mine 14 to form a traveling path 16 on which the transport device 6 travels. The
[0008]
The conveying device 6 is disposed on each of the left and right rails 4 and has a traveling body 6A that reciprocates on the rails 4 and a supporting body 6B that is supported between the traveling bodies 6A and has a gripping portion 6C that grips and suspends the segment 8. Etc.
The support body 6B is supported between the traveling bodies 6A so as to be swingable so as to be always maintained in a vertical state, and thereby the support state of the segment 8 is stabilized even if the extending direction of the traveling path 16 is different. It is like that.
The grip portion 6C is pivotally supported by the support 6B, so that the segments 8 can be easily stacked and unloaded.
[0009]
The segment stock device 18 is provided so as to be able to swivel in a horizontal plane, and includes a rotating plate 24 on which the segment 8 is placed on the outer peripheral portion at intervals in the circumferential direction, driving means 26 for rotating the rotating plate 24, and the like. .
The rotating plate 24 is arranged so that the segment 8 placed on the rotating plate 24 is positioned below the rail 4 on which the transport device 6 travels.
In the present embodiment , as shown in FIGS. 2 and 3 , the rotating plate 24 is arranged such that the center of rotation 0 is located outside the rail 4 and half of the rotating plate 24 is located outside the rail 4 in plan view. Has been.
The rotary plate 24 has a radius larger than the length of the segment 8 in the longitudinal direction (the arc direction of the segment). In the embodiment, the rotary plate 24 has a length similar to the width between the left and right rails 4.
As shown in FIG. 1, the rotating plate 24 is supported by supporting an annular ring 30 provided on the outer peripheral portion of the lower surface of the rotating plate 24 on a support roller 32.
[0010]
Eight concave segment mounting bases 22 on which the segments 8 are placed are fixed to the outer peripheral portion of the rotating plate 24 at predetermined intervals in the circumferential direction.
As shown in FIG. 2, the arrangement of the segment table 22 may be inclined by 45 ° from the radial direction to the rotation direction when the longitudinal direction is right rotation, and as shown in FIG. 3, You may arrange | position so that the longitudinal direction of the segment mounting base 22 may follow a radial direction.
[0011]
As shown in FIG. 2 and FIG. 3, the position where the segment mounting base 22 is positioned approximately at the center of the pair of rails 4 is the position where the transport device 6 grips the segment 8, that is, the segment gripping position 28.
The drive device 26 rotates the rotating plate 24 so that each segment table 22 is positioned at the segment gripping position 28. As shown in FIG. 1, the gear 34, the drive pinion 36, the power source 37, and the control device 38 are provided. Etc.
The gear 34 is provided on the lower surface of the rotating plate 24, and a drive pinion 36 is meshed with the gear 34. The drive pinion 36 and the power source 37 are connected. Examples of the power source 37 include a hydraulic motor and an electric motor. Etc. are used.
A control device 38 is connected to the power source 37, and rotation control is performed by the control device 38 so that the rotating plate 24 stops at each segment gripping position 28.
[0012]
Next, the operation will be described.
The segment 8 carried in by a truck or the like is placed on each segment table 22 on the rotary plate 24 from the opposite side of the segment gripping position 28 by an overhead crane, a forklift or the like.
After placement, the rotating plate 24 is rotated by the driving device 26 so that the rotating plate 24 is positioned at each segment gripping position 28.
Then, the segment 8 on the segment table 22 is held by the transport device 6 and suspended.
The transport device 6 travels along the rail 4, moves to a predetermined location in the pit 14 (for example, on the carriage 20), and loads and unloads the segments 8 on the carriage 20.
After unloading, the vehicle travels along the rail 4 to transport the next segment 8, returns to the ground 10, and stops at the segment gripping position 28.
This operation is repeated, so that the segment 8 is continuously carried into the mine shaft 14.
[0013]
According to the present embodiment, since the segment mounting table 22 is arranged on the rotating plate 24 along the circumferential direction thereof, it is needless to say that the segment 8 can be efficiently gripped by the transport device 6. The total length of the segment stock site can be shortened compared to the case where 8 is arranged on a straight line below the rails 4, and it is possible to achieve compactness.
For example, as shown in FIG. 4, when eight segment mounting tables 22 are arranged on the rotating plate 24 so that the longitudinal direction thereof is along the radial direction, the diameter of the rotating plate 24 is about 6 m and the total length of the segment stock site is about 10 m. Thus, as shown in FIG. 5, the total length can be reduced by about 8 m as compared with the case where seven segment platforms 22 are arranged on a straight line below the rails 4.
[0014]
Further, since the half of the rotating plate 24 is disposed outside the rail 4, this portion can be used as a part of the stock yard. For example, the sticking of the segment 8 carried into the stock yard by a truck or the like can be performed after the segment 8 is placed on the rotating plate 24.
Further, as shown in FIG. 2, the segment table 22 is arranged on the rotating plate 24 so that the longitudinal direction thereof is inclined by 45 ° from the radial direction to the rotating direction. 8 can be placed.
Further, as shown in FIG. 3, the segment table 22 is arranged so that the longitudinal direction thereof is along the radial direction, whereby the arrangement of the segments 8 is neatly arranged, and the sticking of the seal to the segment 8 is facilitated.
