Description

[Technical Field]

[0001] The present invention relates to a horizontal moving body, a horizontal moving device, a horizontal moving system, and a pipe rail mounting base for horizontally moving materials used to erect scaffolding. [Background technology]

[0002] Scaffolding used in construction work is completed by assembling various components (hereinafter referred to as "scaffolding components") such as steel pipe supports, antis (scaffolding boards, treads) that serve as work floors, and handrails in multiple layers. When assembling this multi-level scaffolding, the first level is assembled first, and then the worker moves around the assembled work floor of the first level while assembling the second level of scaffolding. This process is repeated, with the worker moving around the assembled work floor of the next level while assembling the scaffolding, until the final level of scaffolding is assembled. The worker must then carry or manually carry the scaffolding members required for assembling the next rung while moving across the work floor to assemble the next rung. Furthermore, when assembling scaffolding on the roof of a building, the necessary scaffolding components must first be brought onto the roof and placed in specific locations, and then workers must assemble the scaffolding components while moving them by hand. In this case, it takes a great deal of effort and time for workers to move around on the already assembled steps by holding or carrying the scaffolding components by hand, so it is convenient to have a moving device that can carry multiple scaffolding components and move them over the already assembled scaffolding, especially over horizontally installed pipe rails, as well as a platform on which to place the pipe rails. Various proposals have been made regarding vehicles and devices that move on horizontally installed pipes.

[0003] For example, Patent Document 1 (Japanese Utility Model Application Publication No. 6-6149) discloses a bogie in which a pair of pipes 4 are each inserted with a bolt 5, and a pair of C-shaped steel beams 3 are fastened together with the bolts 5 protruding from each pipe 4 so that their side walls are parallel to each other to form an underframe 1, and a support member 9 is provided which fits into the inner surface of the C-shaped steel beam 3 and is fixed thereto with the bolts 5, and a connecting plate 11 which has a roughly V-shaped cross section and protrudes outward from the support member 9 is formed along the longitudinal direction of the C-shaped steel beam 3, and a pair of rollers 8 are axially attached to the connecting plate 11 so that they are facing each other and abut against a pipe-shaped track 12. However, in the bogie of Patent Document 1, a pair of rollers 8 are axially attached to the connecting plate 11 using screws 8b via bearings 8a, which creates a problem in that the screws 8b may loosen due to vibrations or the like while the bogie is running, causing the rollers 8 to fall off the connecting plate 11 and making it impossible for the bogie to run. Furthermore, in the bogie of Patent Document 1, the pair of rollers 8 are axially attached to the connecting plate 11 by separate screws 8b, and therefore there is a risk that the axle attachment positions may shift in the running direction of the bogie. If the axle attachment positions of each of the pair of rollers 8 shift in the running direction of the bogie, and the track pipe is deformed into a wavy shape or curved, etc., and the straightness of the track pipe is lost, there will be a problem that the bogie will not be able to run smoothly on the track pipe. Furthermore, in the bogie of Patent Document 1, when the support member 9 is placed on the track pipe, in order to have the outer circumferential surfaces of the pair of rollers 8 abut against the track pipe without the ridge line of the connecting plate 11 contacting the track pipe, each of the pair of rollers 8 needs to be spaced the same distance from the connecting plate 11, and it is not easy to adjust each roller 8 to be the same distance away from the connecting plate 11. If the adjustment is incorrect and the distance between each roller 8 and the connecting plate 11 is different, the bogie will tilt or only one of the rollers 8 will abut against the track pipe, causing the problem that the bogie will not be able to run stably on the track pipe.

[0004] Next, Patent Document 2 (JP 2012-56492 A) discloses a pipe rail traveling device 1 in which wing-shaped inclined sections 3 are formed at the same inclination angle on both the left and right sides of both ends along the longitudinal direction of a base member 2, support shafts 4 are protruding from these inclined sections 3, bearings 5 ​​are attached to these support shafts 4, and wheels 9 are formed to straddle and come into contact with the upper outer periphery of pipes 7 that form traveling rails 10, and pipe clamps 13 are joined integrally to the top of the base member 2 of this pipe rail traveling device 1, and the pipe rail traveling device 1 is connected by the pipe clamps 13 to both sides of two lower frame pipes 18 that are arranged at a distance on top of traveling rails 10 formed by two pipes 7 arranged in parallel, and an upper frame pipe 19 that is arranged perpendicular to and at a distance from the lower frame pipes 18 is connected to the top of the lower frame pipes 18 by orthogonal pipe clamps 21, and the wheels 9 formed by the bearings 5 ​​run on the traveling rails 10 so that they straddle the traveling rails 10. However, in the trolley of Patent Document 2, a bearing 5 is attached to a support shaft 4 that protrudes from this inclined section 3, but in order to removably attach the bearing 5 to the support shaft 4, the support shaft 4 must be screwed or otherwise made removable from the inclined section 3. In that case, as in Patent Document 1, there is a risk that the screw on the support shaft 4 may loosen due to vibration or the like while the trolley is running, causing the bearing 5 to fall off the inclined section 3, making it impossible for the trolley to run. Furthermore, in the trolley of Patent Document 2, the bearings 5 ​​that face each other across the running rail 10 are attached to separate support shafts 4 that protrude from the inclined section 3, so there is a risk that the position of each support shaft 4 will shift in the axial direction of the running rail 10. If the position of each support shaft 4 shifts in the axial direction of the running rail 10, as in Patent Document 1, the running rail 10 will become wavy or curved, causing a lack of linearity in the running rail 10, which will result in the trolley being unable to run smoothly on the running rail 10. Furthermore, in the trolley of Patent Document 2, the left and right ends of the base member 2 along the longitudinal direction are bent diagonally upward in a wing-like shape to form the inclined portions 3, but it is not easy to bend the base member 2 so that the inclination angles of the left and right inclined portions 3 are the same, and if the inclination angles of the left and right inclined portions 3 are different, as in Patent Document 1, the trolley will tilt or one of the bearings 5 ​​will come off the running rail 10, resulting in the trolley being unable to run stably on the running rail 10.

As shown in FIGS. 8 and 9, the pipe rail mounting base 60 is made up of a first pipe rail mounting base 61 and a second pipe rail mounting base 62 that are arranged at a fixed interval. The first pipe-type mounting base 61 is composed of a vertical pipe fitting base 61a and Y-shaped plates 61b and 61c.

The vertical pipes 63a and 63b are fixed circular pipes made of metal that extend in the vertical direction (Z direction) and serve as the base of the scaffolding, and are arranged side by side in the front-to-rear direction (Y direction).

In this case, protruding pins (not shown) are provided on the vertical pipes 63a and 63b, and pin holes into which the protruding pins fit are provided on the vertical pipes 61a2 and 61a3. When the vertical pipes 61a2 and 61a3 are fitted into the vertical pipes 63a and 63b, the protruding pins fit into the pin holes, preventing the vertical pipes 61a2 and 61a3 from slipping off the vertical pipes 63a and 63b.

In the pipe rail mounting base 60, the first pipe-shaped mounting base 61 is attached to vertical pipes 63a and 63b, and the second pipe-shaped mounting base 62 is attached to vertical pipes 63c and 63d.
