  By the way, when inspecting and repairing railways and road tunnels, the working time is often limited to the night when the railway operation is stopped or the traffic volume is reduced. In such a case, if it takes time to assemble or disassemble the scaffold, it is impossible to secure a sufficient work time. Therefore, it is conceivable to make the scaffold mobile and shorten the installation time for each work location. .

  On the other hand, if the scaffold is made large, workability will be improved because the workable range will be widened, but the amount of materials that make up the scaffold will increase accordingly, and the time taken for the placement of the scaffold will become longer.

The number and arrangement of the wheels 21 can be arbitrarily changed according to the size of the pedestal 24. By arranging an insulator such as a rubber member on a portion of the wheel 21 that is in contact with the railroad rail 12, occurrence of a track short circuit can be suppressed.

  When the side from which the wheel 21 protrudes in the pedestal 24 is the lower surface side, it is preferable that the four jacks constituting the angle adjusting mechanism 25 are detachably mounted on the upper surface side of the pedestal 24 at a position corresponding to the axle 23. When the railway rail 12 is inclined by a curve or the like, a horizontal scaffolding is secured by appropriately expanding and contracting the four jacks constituting the angle adjusting mechanism 25 as shown by the two-dot chain line and the solid line in FIG. can do. Also, four jacks can be used to adjust the height of the movable base 50.

  As shown in FIGS. 2 and 3, the rotation mechanism 30 includes a support frame 32 having a rectangular frame shape in plan view that is detachably mounted on four jacks constituting the angle adjustment mechanism 25, and forms an annular shape. The rotating body 31 is rotatably supported on the support housing 32.

  As shown in FIG. 3, the rotation mechanism 30 preferably includes a rotation restricting portion 33 that restricts the rotation of the rotating body 31. For example, the rotation restricting unit 33 includes a moving body that locks the rotating body 31 when moving toward the rotation center of the rotating body 31, and the rotation mechanism 30 moves the rotation restricting unit 33. 34. Then, when the rotation restricting portion 33 is moved by the rotation operation of the operation portion 34 and engaged with the engaging portion 31 a provided on the rotating body 31, the rotation of the rotating body 31 is restricted. The engaging portions 31a can be provided at predetermined intervals along the outer edge of the rotating body 31, for example.

  As shown in FIG. 4, a scaffolding rail 41 made of a pair of channel steels connected by a connection reinforcing member 42 is fixed on the annular rotating body 31. The scaffolding rail 41 can be changed to any length. In this way, the movable base 50 is detachably disposed on the scaffolding rail 41 fixed to the rotating body 31. The movable platform 50 includes a plurality of (for example, four) rollers 51 that are slidably engaged with the scaffold rail 41, a rectangular plate-shaped scaffold platform 52 that supports the rollers 51 rotatably, It is preferable that the roller 51 is engaged with the groove of the grooved steel constituting the scaffolding rail 41 from the inside.

  Further, as shown in FIG. 5, the length of the scaffolding rail 41 may be extended by detachably connecting the rail extension 60 to the scaffolding rail 41. In this case, the rail extension portion 60, similarly to the scaffold rail 41, includes a connection rail 61 made of a pair of channel steels connected by a connection reinforcing material 62, and a support column 63 that can support the connection rail 61. It is good to have.

  The position of the column 63 can be arbitrarily set according to the length of the connecting rail 61 and the like. For example, it is preferable to dispose the columns 63 at the joint between the scaffolding rail 41 and the connecting rail 61, or at the intermediate portion of the connecting rail 61, and the like, which can effectively suppress the deflection of the rails 41 and 61.

  When the rotating body 31 is rotated with respect to the support housing 32, the movable base 50 and the scaffolding rail 41 are also rotated together with the rotating body 31, so that the direction of the movable base 50 is changed, or along the scaffolding rail 41, It becomes possible to move the movable base 50 in a direction different from the extending direction of the rails 12 for railroad. The rail extension 60 may be coupled to the scaffolding rail 41 after the scaffolding rail 41 is pivoted together with the pivoting body 31.

  As shown in FIG. 6, the movement restricting portion 53 is configured to be displaceable between a state of being placed on the top surface of the rails 41 and 61 and a state of being apart from the rails 41 and 61 (the state shown in FIG. 1). Leg. When the movement restricting portion 53 is placed on the top surface of the rails 41 and 61, the weight of the movable base 50 is supported by the rails 41 and 61 via the movement restricting portion 53, so that the roller 51 is rotated. The movement of the movable table 50 is restricted. On the other hand, when the movement restricting portion 53 is separated from the rails 41 and 61, the weight of the movable table 50 is supported by the rails 41 and 61 via the rollers 51, and the movable table 50 is rolled by the rollers 51. It becomes possible to move along the rails 41 and 61.

  When the scaffolding rail 41 and the coupling rail 61 are coupled, or when the coupling rails 61 are coupled to each other, for example, a coupling fitting 64 as shown in FIG. 6 may be used. The connection fitting 64 has a base end side (left end side in FIG. 6) fixed to the scaffolding rail 41 by welding or the like, and a collar portion 64a provided on the distal end side (right end side in FIG. 6) is provided with a connection rail 61. It is latched by the latching protrusion 61a provided in the. Further, the head portion of the bolt 65 is locked in an insertion hole (not shown) provided in the fixed protrusion 43 provided in the scaffolding rail 41, and the shaft portion of the bolt 65 is connected to the locking protrusion of the connecting rail 61. The coupling between the scaffolding rail 41 and the coupling rail 61 may be strengthened by screwing into a screw hole (not shown) of the screwing portion 66 provided in 61a.

  As shown in FIG. 7, the movable platform 50 supports a scaffold structure 55 assembled on the scaffold platform 52. The scaffold structure 55 includes an outer frame 56 that also functions as a handrail, one or a plurality of floor boards 57, a ladder 58 that connects a plurality of floor boards 57 that are spaced apart from each other, and the like. Can be changed. The movable platform 50 and the scaffold structure 55 can be used while moving one of the scaffolds 41 arranged on the scaffold rail 41 toward the connecting rail 61. Alternatively, as shown in FIG. A plurality of movable platforms 50 and scaffolding structures 55 can also be arranged on the top.

Next, the operation of the mobile scaffold device 11 of this embodiment will be described.
When inspecting tunnels and bridges, etc., that are located along the railway line, move to a high place while moving within a limited time (about 3 hours) at night when the railway operation is suspended. It is necessary to install a scaffold for the work.

  In that respect, in the mobile scaffold device 11 of the present embodiment, the carriage 20 that supports the scaffold structure 55 has the wheels 21 that can roll on the rails for rails 12. The scaffold can be easily moved along the rail 12. In addition, after the carriage 20 has moved, the carriage 20 can be stopped by restricting the rotation of the wheels 21 by the brake mechanism 22.

  Moreover, since the moving scaffold apparatus 11 is provided with the rotation mechanism 30 arrange | positioned between the trolley | bogie 20 and the movable stand 50, the direction of the movable stand 50 can be changed arbitrarily by rotating the rotary body 31. it can. And since the rotation mechanism 30 supports the structure 55 for scaffolds which comprises the scaffold for work via the rotation body 31, the direction of the structure 55 for scaffolds is rotated by rotating the rotation body 31. As shown in FIG. Can be changed.

  Moreover, after adjusting the direction of the movable stand 50, the rotation restricting portion 33 restricts the rotation of the rotating body 31, whereby the scaffold can be stabilized. Since the movement, rotation, and stop of these can be easily performed by human power, it is not necessary to prepare power for movement or rotation, and can be used in any place such as in the mountains. .

  Further, by moving the movable platform 50 by rolling the roller 51 of the movable platform 50 on the scaffolding rail 41 and the connecting rail 61, the working range is separated from the rail 12 on which the carriage 20 is placed. Can be extended to different positions. For example, when inspecting a tunnel in a double track section, one or a plurality of connecting rails are arranged such that the carriage 20 is arranged on one rail 12 and extends on the rail 12 adjacent to the rail 20. If 61 is connected to the scaffolding rail 41, the movable base 50 can be moved along the rails 41, 61. Therefore, even when inspecting a wide tunnel with double tracks, if the carriage 20 is placed on one rail 12 for rail, the entire range in the tunnel can be set as a work range.

  In the mobile scaffold device 11, the angle adjustment mechanism 25, the rotation mechanism 30, and the scaffolding rail 41 are detachably attached to the carriage 20, and the scaffolding rail 41 includes one or more scaffolds. The connecting rail 61 is detachably connected. Therefore, even within the limited time at night, the constituent members can be quickly combined according to the work location, and the scaffold can be secured in a short time or can be disassembled in a short time.

  In the mobile scaffold device 11, the base 24 of the carriage 20 and the support housing 32 of the rotation mechanism 30 are made into a frame shape, for example, so that assembly and disassembly can be easily performed manually by reducing the weight of the constituent members. It becomes possible. In addition, it is possible to quickly perform assembly and disassembly by human power by facilitating the attachment and detachment of the constituent members, such as by using a connection fitting 64 that facilitates the attachment and detachment of the scaffolding rail 41 and the connection rail 61. Moreover, since installation, movement, and dismantling can be performed quickly by human power, it is easy to escape from the track even in the event of an emergency, and the train operation is not hindered.

  As a result of simplifying the work of assembling and disassembling the scaffold structure 55 constituting the scaffold in this way, it becomes possible to secure work time for inspection or repair, thereby reducing the work days. In addition, the number of workers can be reduced, and work such as inspection can be performed efficiently.

According to the embodiment detailed above, the following effects are exhibited.
(1) Since the orientation of the scaffold structure 55 can be freely changed by rotating the pivot body 31 that supports the scaffold structure 55, the workability is good.

(2) Since the working range can be expanded by moving the scaffold structure 55 along the scaffold rail 41 attached to the rotating body 31, workability is good.
(3) By connecting the connecting rail 61 supported by the support column 63 to the scaffolding rail 41, the work range can be extended to a position away from the carriage 20 (or the rail 12 for railways). Is good.

  (4) Since the movement restricting portion 53 restricts the relative movement of the movable platform 50 with respect to the scaffold rail 41, the scaffold structure 55 can be stopped at the time of work, so that workability is good.

(5) By restricting the rotation of the rotating body 31 by the rotation restricting portion 33, the scaffold structure 55 can be stopped at the time of work, so that workability is good.
