The main body frame 2 is formed to have a width dimension in the left-right direction that allows it to move along the travel path R. Further, the main body frame 2 is formed so that the overall length in the front-rear direction is approximately the same as the interval between four panels 110 arranged in the front-rear direction.

Such a main body frame 2 is formed of, for example, aluminum or an aluminum alloy. By forming the main body frame 2 from aluminum or aluminum alloy in this way, the weight of the mobile scaffolding 1 for assembling automatic warehouse racks can be reduced, and the mobile scaffolding 1 for assembling automatic warehouse racks can be easily moved. Become.

A plurality of casters 3 are attached to the bottom of the main body frame 2 and support the main body frame 2 from below. A plurality of casters 3 are provided on each of the left and right sides of the main body frame 2. Each of the casters 3 provided on the left side of the main body frame 2 contacts the floor surface of the building 101 on the left side of the lower rail 103a. Each of the casters 3 provided on the right side of the main body frame 2 contacts the floor surface of the building 101 on the right side of the lower rail 103a. Each caster 3 can roll on the floor surface of the building 101, and supports the main body frame 2 so as to be movable in the front-rear direction (horizontally movable).

The elevating steps 4 are provided at the front end and the rear end of the main body frame 2, respectively. Each lifting step 4 extends from the lower part of the main body frame 2 so as to approach the floor surface of the building 101. By using these lifting and lowering steps 4, a worker can easily climb up and down between the floor and the main body frame 2.

The overhanging scaffold 5 is a scaffold that can extend from the main body frame 2 in the left-right direction. As shown in FIG. 4, the overhanging scaffold 5 is arranged at the rear end side of the main body frame 2. In this embodiment, a plurality of overhanging scaffolds 5 are arranged in the vertical direction. That is, the mobile scaffolding 1 for assembling automated warehouse racks is provided with a plurality of overhanging scaffolds 5 arranged at different heights.

As shown in FIG. 5, in this embodiment, the overhanging scaffold 5 includes a left side overhang scaffold 10 (first overhang scaffold) placed on the left side of the main body frame 2, and a left side overhang scaffold 10 (first overhang scaffold) placed on the right side of the main body frame 2. A right side overhanging scaffold 11 (second overhanging scaffold) is provided. The left side extending scaffold 10 can extend to the left side, which is one side in the horizontal direction orthogonal to the moving direction of the main body frame 2. Further, the right side extending scaffold 11 can extend to the right side, which is the other side in the horizontal direction orthogonal to the moving direction of the main body frame 2.

FIG. 6 is a schematic enlarged view of the overhanging scaffold 5. As shown in this figure, the overhanging scaffold 5 is a plate-shaped portion whose end is pivotally supported with respect to the main body frame 2. The overhanging scaffold 5 can change its posture by rotating around the pivoted part. In this embodiment, such an overhanging scaffold 5 can change its posture between an extended posture and a stowed posture.

The overhanging scaffold 5 is a plate-shaped member whose one side is a top surface 5a that supports a worker. The overhanging posture is a posture shown by a solid line in FIG. 6, and is a posture in which the top surface 5a is directed upward. The overhanging scaffolding 5 is placed in the overhanging posture and becomes in a state of overhanging from the main body frame 2 in the horizontal direction.

In addition, the left side overhanging scaffold 10 will be in a state of overhanging toward the left side from the main body frame 2 by assuming an overhanging posture. In addition, the right-side overhanging scaffold 11 is in an overhanging posture and is in a state of overhanging from the main body frame 2 toward the right side.

The storage posture is a posture shown by imaginary lines in FIG. 6, and is a posture in which the top surface 5a is directed to the side. When the overhanging scaffold 5 is in the housed position, the amount of horizontal overhang from the main body frame 2 is suppressed compared to when in the extended position. Since such an overhanging scaffold 5 is in the storage position, it will not interfere with the rack 102 even if the mobile scaffold 1 for assembling an automated warehouse rack is moved in the front-rear direction.

In addition, the left side overhanging scaffold 10 is in a state in which the top surface 5a is directed to the left side by being in the storage attitude. In addition, the right side overhanging scaffold 11 is in the accommodated attitude, so that the top surface 5a is directed to the right side.

With the overhanging scaffold 5 in such an overhanging posture, the overhanging scaffold 5 will be in a state of being overhanging from the main body frame 2 toward the assembly location of the rack 102. Therefore, the worker can easily move to the assembly location of the rack 102 by passing through the top surface 5a of the overhanging scaffold 5 in the overhanging posture.

The scaffold support section 6 is a tension rod that supports the overhanging scaffold 5 in an overhanging posture from below, and is connected to the main body frame 2. For example, when the overhanging scaffold 5 is in the storage position, the scaffold support part 6 hangs down from the main body frame 2 without supporting the overhang scaffold 5.

In addition, in this embodiment, as shown in FIG. 6, when the overhanging scaffold 5 is changed from the extended position to the stowed position, the overhanging scaffold 5 is rotated so that the tip of the overhanging scaffold 5 faces downward. It is. However, when changing the overhanging scaffold 5 from the extended position to the stowed position, the overhang scaffold 5 may be rotated so that the tip of the overhang scaffold 5 faces upward. That is, in the present embodiment, the overhanging scaffold 5 is rotated so as to be folded downward to change from the overhanging posture to the stowed posture, but by rotating the overhanging scaffold 5 so as to be folded upward, the overhanging posture is changed to the stowed posture. You may also do so. In such a case, for example, a configuration may be adopted in which the scaffold support section 6 suspends and supports the overhanging scaffold 5 in the overhanging posture from above.

The rack abutting portion 7 is a portion that can come into contact from the main body frame 2 side with a part of the rack 102 that is arranged to face the main body frame 2 from the left and right. That is, the mobile scaffolding 1 for assembling automated warehouse racks includes the rack abutting portion 7 that can abut from the main body frame 2 side against a part of the rack 102 that is disposed opposite to the main body frame 2.

The rack abutting portion 7 can extend from the main body frame 2 in the left-right direction, and as shown in FIG. . In this embodiment, a plurality of rack contact portions 7 are arranged in the vertical direction. That is, the mobile scaffolding 1 for assembling automated warehouse racks is provided with a plurality of rack abutting parts 7 arranged at different heights. Furthermore, two rack abutting portions 7 are provided arranged at the same height in the front-rear direction.

As shown in FIG. 5, in this embodiment, the rack abutting parts 7 include a left rack abutting part 12 disposed on the left side of the main body frame 2, and a right rack abutting part 12 disposed on the right side of the main body frame 2. A contact portion 13 is provided. The left rack contact portion 12 can extend to the left side, which is one side in the horizontal direction orthogonal to the moving direction of the main body frame 2. Further, the right rack contact portion 13 can extend to the right side, which is the other side in the horizontal direction orthogonal to the moving direction of the main body frame 2.

FIG. 7 is a schematic enlarged view of the rack contact portion 7. As shown in FIG. As shown in this figure, the rack abutting section 7 is a rod-shaped member whose end is pivotally supported with respect to the main body frame 2. As shown in FIG. The rack abutting portion 7 can change its posture by rotating around the pivotally supported portion. In this embodiment, the rack abutting portion 7 can change its posture between a contacting posture and a storage posture.

The rack contact portion 7 includes a tip portion 7a that comes into contact with the protrusion 114 of the rack 102, an extendable shaft portion 7b, and an operating portion 7c that adjusts the amount of expansion and contraction of the shaft portion 7b. . In this embodiment, the shaft portion 7b expands and contracts by turning the handle of the operating portion 7c. The tip portion 7a is moved in the direction in which the shaft portion 7b extends as the shaft portion 7b expands and contracts.

Note that the mounting position of the rack abutting portion 7 in the vertical direction with respect to the main body frame 2 may be changeable. By being able to change the mounting position in the vertical direction with respect to the main body frame 2, the tip end 7a of the rack contacting part 7 can be reliably brought into contact with the protruding part 114 of the rack 102.

Such a contacting posture of the rack abutting portion 7 is a posture shown by a solid line in FIG. 7, and is a posture in which the shaft portion 7b is parallel to the left-right direction. The rack contact portion 7 extends horizontally from the main body frame 2 by being in the contact attitude.

In addition, the left rack contact portion 12 assumes a position extending to the left from the main body frame 2 by assuming the contact position. In addition, the right side rack abutting portion 13 assumes an abutting attitude, thereby extending from the main body frame 2 to the right side.

The storage position is shown by the imaginary line in FIG. 7, and is a position in which the tip portion 7a is directed diagonally downward. When the rack contact portion 7 is in the storage position, the amount of horizontal extension from the main body frame 2 is suppressed compared to that in the contact position. By being in the storage position, the rack abutting portion 7 does not interfere with the rack 102 even if the mobile scaffolding 1 for assembling automated warehouse racks is moved in the front-rear direction.

Note that when the left rack abutment portion 12 is in the storage position, the tip end portion 7a is directed diagonally downward to the left. Furthermore, when the right side rack abutting portion 13 is in the storage position, the tip end portion 7a is oriented diagonally downward to the right.

When the rack abutting portion 7 assumes the abutting attitude and the tip end 7a abuts the protruding portion 114 of the rack 102, the mobile scaffold 1 for assembling an automated warehouse rack is supported by the rack 102 from the side. Therefore, it is possible to prevent the mobile scaffolding 1 for assembling automated warehouse racks from tilting in the left-right direction.

The upper guide part support part 8 is a frame member connected to the upper part of the main body frame 2, as shown in FIG. The upper guide support portion 8 is provided to protrude forward from the main body frame 2. The upper guide part support part 8 supports an upper guide part 15, which will be described later, which is one of the guide parts 9.

The guide portion 9 is a portion movably connected to rails 103 laid in the automated warehouse 100. The guide portion 9 is guided by the rails 103 when the mobile scaffolding 1 for assembling automated warehouse racks is moved in the front-back direction. The guide section 9 includes, for example, a plurality of guide rollers that come into contact with the rails 103. Note that the guide section 9 does not necessarily need to include a guide roller, and may be configured to include a sliding section that slides on the rail 103.

In this embodiment, the guide section 9 includes a lower guide section 14 and an upper guide section 15. The lower guide portion 14 is provided at the bottom of the main body frame 2, and is connected to the lower rail 103a. The upper guide part 15 is connected to the main body frame 2 via the upper guide part support part 8 and is located above the lower guide part 14.

The upper guide section 15 is fixed to the tip of the upper guide section support section 8 that protrudes forward from the main body frame 2 . As a result, the upper guide portion 15 is disposed further forward than the main body frame 2. In addition, when assembling the rack 102, the automatic warehouse rack assembly movable scaffold 1 is moved from the front side to the rear side. Therefore, the upper guide portion 15 is disposed on the rear side of the main body frame 2 in the direction in which the main body frame 2 moves.
