Description

The present invention relates to an indoor storage facility.

Coal and minerals transported to the plant are temporarily stored in storage facilities, and when and in the required amount, they are discharged. Discharge of stored items such as coal and minerals is performed using a reclaimer (see, for example, Patent Document 1). Such storage equipment is often installed outdoors, in which case particles of the storage may be scattered by the wind in the vicinity. On the other hand, if it is an indoor storage facility equipped with a building, it is possible to prevent the storage from scattering.

JP-A-2019-59605

However, since the indoor storage facility is equipped with a building, the construction cost is higher than that of the outdoor storage facility. Therefore, in order to reduce the construction cost of the indoor storage facility, the inventors of the present invention focused on the maintenance area of the reclaimer.

Since the reclaimer requires maintenance using heavy machinery, it is necessary to secure a maintenance area where heavy machinery can enter in the storage facility equipped with the reclaimer. If this maintenance area can be omitted or reduced in the indoor storage facility, the size of the building can be suppressed, and the construction cost of the indoor storage facility can be suppressed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an indoor storage facility in which the maintenance area of the reclaimer can be omitted or reduced and the reclaimer is highly maintainable.

The indoor storage facility according to one aspect of the present invention includes a storage table on which the storage is loaded, a reclaimer that scrapes the storage on the storage table and discharges the storage in a predetermined payout direction, and the storage table. A rail located outside the payout direction and running the reclaimer along the storage table, a conveyor located outside the storage table in the payout direction and carrying the reclaimer paid out, and the storage table. A building that houses the reclaimer, the rail, and the conveyor and has at least one opening formed on the wall surface on the payout direction side, and a floor surface and the storage near the opening beyond the rail and the conveyor. It includes a bridge position that bridges the platform and a bridge that can move between retracted positions that do not interfere with the traveling reclaimer.

According to this configuration, when the bridge is in the bridge position, heavy equipment can move across the bridge onto the storage table. Therefore, the heavy machine can perform the maintenance work of the reclaimer on the storage table. As a result, the reclaimer maintenance area can be omitted or reduced. Further, since the heavy machine can be arranged in the vicinity of the reclaimer, the reclaimer is easy to maintain.

According to the above configuration, it is possible to omit or reduce the maintenance area of the reclaimer, and it is possible to provide an indoor storage facility having high reclaimer maintainability.

As shown in FIGS. 1 and 2, the indoor storage facility 100 according to the present embodiment includes a storage stand 10, a reclaimer 20, a rail 30, a conveyor 40, a building 50, and a bridge 60. .. Hereinafter, these components will be described in order.

The storage table 10 is a portion on which a storage material 101 such as coal or mineral is loaded. As shown in FIGS. 1 and 2, the storage table 10 of the present embodiment includes a base portion 11 located below, a central wall 12 located at the center of the base portion 11 in the left-right direction and extending in the front-rear direction, and a central wall 12. It has a plurality of partition walls 13 extending from the left and right sides, respectively. The upper surface of the storage table 10 is a storage area 14 on which the storage material 101 is loaded, and the storage area 14 is divided by a central wall 12 and a partition wall 13.

As shown in FIG. 2, the upper surface of the base portion 11 is inclined so that the central portion in the left-right direction is low and the end portion in the left-right direction is high. Further, both ends of the base portion 11 in the left-right direction project outward in the left-right direction and are located above the floor surface. The upper surface of the base portion 11 may be horizontal. Further, both ends of the base portion 11 in the left-right direction may be located at the same height as the floor surface.

The reclaimer 20 is a device for discharging the stored material 101 loaded on the storage table 10. The indoor storage facility 100 according to the present embodiment includes four reclaimers 20, two of which are arranged on the right side of the storage table 10 and two on the left side of the storage table 10. However, the number of reclaimers 20 included in the indoor storage facility 100 is not particularly limited. The reclaimer 20 of the present embodiment is a traveling device 21 that travels in the front-rear direction along the base portion 11, a portal 22 that extends from the traveling device 21 toward the upper end surface of the central wall 12 of the storage base 10, and a traveling device 21. It has a boom 23 extending toward the center in the left-right direction of the base portion 11.

The tip of the portal 22 is supported by the upper end surface of the central wall 12, and is configured to be movable in the front-rear direction along the upper edge surface of the central wall 12. The reclaimer 20 of the present embodiment is a "semi-portal type" in which the portal 22 extends from one end side in the left-right direction of the storage area 14 (storage stand 10) to the central portion, but the portal 22 is one end in the left-right direction of the storage area 14. It may be a "full portal type" extending from the side to the end side. Further, when the reclaimer 20 is a semi-portal type, the left half or the right half of the storage table 10 can be omitted.

The boom 23 has a drive unit 25 formed of a huge chain orbiting around the arm 24, and a plurality of scrapers 26 having a plate-like shape and provided on the drive unit 25. As the drive unit 25 goes around, the scraper 26 scrapes the stored material 101 loaded on the storage table 10 and discharges it in a predetermined payout direction (see the white arrow in FIG. 2). In the present embodiment, the storage 101 loaded on the left side of the central wall 12 is paid out to the left, and the storage 101 loaded on the right side of the central wall 12 is paid out to the right.

Further, the boom 23 is rotatably supported by the traveling device 21 at the base end portion and is suspended from the portal 22 via the hanging wire 27. Therefore, if the length of the hanging wire 27 is adjusted, the elevation angle of the boom 23 changes, and the boom 23 can be arranged at an appropriate position with respect to the storage 101. The reclaimer 20 of the present embodiment is a "scraper type" in which the storage material 101 is scraped and discharged by the scraper 26, but a reclaimer other than the scraper type may be used.

The rail 30 is laid so as to extend in the front-rear direction along the storage table 10. The traveling device 21 of the reclaimer 20 travels along the rail 30. That is, the reclaimer 20 travels in the front-rear direction along the rail 30. The rail 30 of the present embodiment is located outside the storage table 10 in the left direction and outside in the right direction. That is, the rail 30 is located outside the storage table 10 in the payout direction. Further, the rail 30 is laid on the floor surface and is located at a position lower than the left-right end portion of the base portion 11. However, unlike the case of the present embodiment, when the left-right end portion of the base portion 11 is at the same height position as the floor surface, the rail 30 is laid at a position lower than the floor surface.

The conveyor 40 is a device for transporting the storage 101 discharged by the reclaimer 20. The conveyor 40 extends in the front-rear direction along the storage table 10. In the present embodiment, the conveyor 40 conveys the storage 101 rearward and supplies the storage 101 to a facility different from the indoor storage facility 100 located outside the indoor storage facility 100. The conveyor 40 may convey the stored material 101 forward. The conveyor 40 is left-sided and right-sided (that is, outside in the payout direction) and is located between the storage table 10 and the rail 30. Further, the conveyor 40 is located below the left-right end of the base 11 to receive the storage 101 discharged from the storage base 10. That is, in a plan view, a part of the conveyor 40 overlaps with the left-right end portion of the base portion 11.

The building 50 houses the storage stand 10, the reclaimer 20, the rail 30, and the conveyor 40. The building 50 has a left side wall 51, a right side wall 52, a front wall 53, a rear wall 54, and a roof 55. In the present embodiment, a plurality of openings 56 (see FIG. 3) are formed on the left side wall 51, and the openings 56 are arranged at predetermined intervals in the front-rear direction. Similarly, a plurality of openings 56 are formed on the right side wall 52, and the openings 56 are arranged at predetermined intervals in the front-rear direction. As described above, a plurality of openings 56 are formed in the side walls 51 and 52 on the payout direction side of the building 50. Each opening 56 of the present embodiment can be opened and closed by a door (not shown). Further, the opening 56 has an opening area sufficient for a heavy machine for maintenance of the reclaimer 20 to pass through.

The bridge 60 is a device that bridges between the floor surface in the vicinity of the openings 56 formed in the side walls 51 and 52 and the storage table 10. FIG. 3 is a perspective view of the bridge 60, which is a view seen from the center of the storage table 10 in the left-right direction toward the left wall 51. The bridge 60 is arranged in the vicinity of the left side wall 51 and is arranged in the vicinity of the right side wall 52. The bridges 60 arranged in each of them are configured in the same manner. Therefore, the bridge 60 arranged in the vicinity of the left side wall 51 will be described below, and the description of the bridge 60 arranged in the vicinity of the right side wall 52 will be omitted.

As shown in FIG. 3, the bridge 60 of the present embodiment is provided on the frame member 61. The frame member 61 includes an upper frame portion 62 that is located in the upper portion and extends in the front-rear direction, a front frame portion 63 that extends downward from the front end portion of the upper frame portion 62, and a lower end portion of the upper frame portion 62. It has a rear frame portion 64 extending toward it. The frame member 61 of the present embodiment has an opening area similar to that of the opening 56.

Above the frame member 61, a frame rail 65 extending in the front-rear direction over the entire building 50 is provided. A plurality of rollers 66 are provided on the upper frame portion 62 of the frame member 61. The frame member 61 is suspended from the frame rail 65 via these rollers 66, and the frame member 61 can move in the front-rear direction along the frame rail 65. As a result, the bridge 60 attached to the frame member 61 can move along the side walls 51 and 52 on the payout direction side of the building 50, and the bridge 60 can be arranged at a position corresponding to each opening 56. it can.

The bridge 60 has a connecting portion 67 at the lower end portion, and is connected to the lower portion of the front frame portion 63 and the lower portion of the rear frame portion 64 via the connecting portion 67. The bridge 60 rotates up and down around the connecting portion 67. That is, the bridge 60 rotates about a rotation shaft 68 that passes through the lower portion of the frame member 61 and extends in the front-rear direction.

A winch 69 is provided at the boundary between the upper frame portion 62 and the front frame portion 63 of the frame member 61, and similarly, a winch 69 is provided at the boundary portion between the upper frame portion 62 and the rear frame portion 64 of the frame member 61. ing. A wire 70 is wound around these winches 69, and the tip of each wire 70 is attached to an upper portion of the bridge 60. Therefore, by driving the winch 69, the bridge 60 rotates about the rotation shaft 68.

The bridge 60 of the present embodiment can be moved between the "bridge position" and the "evacuation position" by driving the winch 69. The cross-linking position is a position where the floor surface near the opening 56 and the storage table 10 are bridged. By feeding out the wire 70 from the winch 69, the bridge 60 can be positioned at the cross-linking position. FIG. 3 shows a state in which the bridge 60 is located at the bridge position. As shown in FIG. 3, when the bridge 60 is located at the bridge position, the bridge 60 functions as a slope connecting the floor surface and the storage table 10 beyond the rail 30 and the conveyor 40.

On the other hand, the retracted position is a position that does not interfere with the traveling reclaimer 20. When the bridge 60 is in the above-mentioned bridge position, the bridge 60 interferes with the traveling reclaimer 20. Therefore, when the reclaimer 20 is driven, the bridge 60 is positioned at the retracted position. In the present embodiment, when the bridge 60 is located in the retracted position, the bridge 60 is substantially perpendicular to the floor surface (see FIG. 2). The winch 69 winds up the wire 70 so that the bridge 60 can be positioned in the retracted position.

As described above, the indoor storage facility 100 according to the present embodiment is a reclaimer 20 that scrapes the storage table 10 on which the storage material 101 is loaded and the storage material 101 loaded on the storage table 10 and discharges them in a predetermined payout direction. A rail 30 located outside the storage table 10 in the payout direction and running the reclaimer 20 along the storage table 10 and a storage 101 located outside the storage table 10 in the payout direction and paid out by the reclaimer 20.

It includes a bridge position that bridges the floor surface near the opening 56 and the storage table 10 and a bridge 60 that can move between the retracted positions that do not interfere with the traveling reclaimer 20.

As described above, in the indoor storage facility 100 according to the present embodiment, by locating the bridge 60 at the bridge position, the heavy machinery can enter the storage table 10 across the bridge 60. Therefore, maintenance of the reclaimer 20 using heavy machinery can be performed on the storage table 10. As a result, it is not necessary to provide a maintenance area separate from the storage table 10 (storage area 14). The indoor storage facility 100 may be provided with a maintenance area, but even in this case, a large maintenance area capable of accommodating a plurality of reclaimers 20 is unnecessary, and the maintenance area can be reduced. Further, according to the indoor storage facility 100 according to the present embodiment, since the heavy machinery can be arranged in the vicinity of the reclaimer 20, the reclaimer 20 is highly maintainable.

Further, in the indoor storage facility 100 according to the present embodiment, a plurality of openings 56 are formed in the side walls 51 and 52 on the payout direction side of the building 50, and the bridge 60 is the side wall 51 on the payout direction side of the building 50. It is configured to be movable along 52.

Therefore, in the present embodiment, the bridge 60 can be moved to a position corresponding to each opening 56, and as a result, it is not necessary to provide the bridge 60 corresponding to each opening 56, and the number of bridges 60 is suppressed. can do.

However, a bridge 60 may be provided for each opening 56. FIG. 4 is a perspective view of the bridge 60 according to the modified example. As shown in FIG. 4, the bridge 60 may be provided directly in the opening 56 so as to close the opening 56 when it is in the retracted position. In this case, the bridge 60 rotates about a rotation shaft 68 extending in the front-rear direction in the lower portion of the opening 56. According to this configuration, since the bridge 60 can close the opening 56 when it is in the retracted position, the bridge 60 can function as a door of the opening 56. As a result, it is not necessary to provide the door of the opening 56 separately from the bridge 60.

Further, in the indoor storage facility 100 according to the present embodiment, the bridge 60 rotates around a rotation shaft 68 extending parallel to the side walls 51 and 52 on the payout direction side of the building 50 in the vicinity below the opening 56. It is configured to work. Therefore, the bridge 60 can easily move between the bridge position and the retracted position.

Further, in the present embodiment, the winch 69 and the wire 70 are used to rotate the bridge 60, but the bridge 60 may be rotated by a different mechanism. For example, the bridge 60 may be rotated by using a hydraulic cylinder or an electric cylinder. Further, the bridge 60 may be moved between the bridge position and the retracted position without rotating the bridge 60. For example, the bridge 60 may be moved up and down to move between the bridge position and the retracted position.

Further, the bridge 60 of the present embodiment may be configured to be foldable as shown in FIG. The bridge 60 shown in FIG. 5 includes a lower plate portion 71, an upper plate portion 72 that is rotatable with respect to the lower plate portion 71, and an electric cylinder 73 that rotates the upper plate portion 72 with respect to the lower plate portion 31. I have. Then, when the bridge 60 is in the retracted position, the bridge 60 is folded, and when the bridge 60 is in the bridge position, the bridge 60 is unfolded. If the bridge 60 is configured to be foldable in this way, the height of the bridge 60 when it is in the retracted position can be suppressed.

When the bridge 60 is configured as shown in FIG. 5, a hydraulic cylinder or an electric cylinder for moving the bridge 60 between the bridge position and the retracted position may be provided in the lower plate portion 31. Further, the bridge 60 may be configured to be expandable and contractible. For example, if the lower plate portion is configured so that the upper plate portion can be accommodated inside and the upper plate portion is configured to be slidable inside the lower plate portion, the bridge 60 can be expanded and contracted. Also in this case, the height of the bridge 60 when it is in the retracted position can be suppressed.
