FIGS. 1 to 3 show an assembled maintenance work gantry, and 1A and 1B are two trolleys having the same structure. The truck 2 has a rectangular carriage 2 and an enclosing frame 3 erected from the periphery of the carriage 2. The carriage 2 is formed of two corners of one of the rectangular peripheral frames 4 at both ends of one long side. A fixed wheel 5 fixed in a direction parallel to the short side is attached to the lower side of the part, and a free wheel rotatable around a vertical axis is provided below the other end of the other long side. A bottom plate 7 made of expanded metal or the like is laid above the peripheral frame 4. The surrounding frame 3 includes a surrounding frame 8 which is the same as the surrounding frame 4 of the bogie unit 2, four supporting members 9 for connecting the corners of the two surrounding frames 4, 8, and supporting members 9 at both ends of both short sides. And a transverse member 10 installed at an intermediate height.
[0010]
Each of the trolleys 1A and 1B will be described below with the long side on which the directionally fixed wheel 5 is disposed on the inside and the long side on which the free wheel 6 is disposed on the outside. At the upper end of the support member 9, there are provided connecting member mounting portions 11a and 11b having screw holes and the like. By using the connecting member mounting portions 11a and 11b, the two carts 1A and 1B In use, they are connected by two connecting members 12A and 12B. That is, the connecting members 12A and 12B are provided at both ends with mounting plates 14 which are removably fastened to the connecting member mounting portions 11a and 11b of the two carts 1A and 1B by the bolts 13 and extend in the longitudinal direction. A hanging portion 17 of a chain block (work hanging tool) 16 composed of an eye plate 15 fixed to the side surface at the center position is provided. Thus, the two carts 1A and 1B are connected to each other by the two connecting members 12A and 12B in a state where the two carts 1A and 1B face each other with the insides thereof facing each other across the work suspension space S as shown in FIG. Will be done.
[0011]
Between the two connecting members 12A, 12B, two lateral connecting members 18A, 18B are detachably mounted. As shown in FIG. 3, the lateral connecting members 18A and 18B have hook members 19 at both ends which can be fitted and locked to the connecting members 12A and 12 from above. Can be installed between the connecting members 12A and 12B only by fitting the connecting members 12A and 12B from above, but the hook member 19 fitted to the connecting members 12A and 12B is connected to the connecting members 12A and 12B.

[0012]
As described above, the maintenance work suspension frame composed of the two carts 1A and 1B integrally connected by the connection members 12A and 12B is used to make the floor using the wheels 5 and 6 at the bottom of the carts 1A and 1B. It can be moved freely on the surface. Therefore, for example, a transport train as shown by a virtual line in the drawing, that is, a train that is self-propelled by an autopilot mechanism on a fixed route set on the floor surface, and transports the load to the upper side in the left and right lateral direction. When performing maintenance work and the like of the transport train 21 provided with the transfer conveyor 20, the transport train 21 stopped on the floor enters the work suspension space S between the two carriages 1A and 1B. The two carts 1A and 1B are moved together as described above. When the two connecting members 12A and 12B connecting the two carts 1A and 1B are located at predetermined positions above the transport train 21, the two connecting members 12A and 12B are suspended by using the hanging parts 17 of the hanging members. The transport train 21 is hoisted to a predetermined height above the floor surface using the two right and left chain blocks 16 and an appropriate hanging cable 22.
[0013]
The transport train 21 lifted as described above can be transported to the maintenance work support stand 23 installed on the floor surface by moving the two carriages 1A and 1B together. Of course, depending on the case, in a state where the transport train 21 is lifted from the floor surface as described above, the maintenance work support base 23 may be loaded and installed on the lower floor surface of the transport train 21. . In any case, if the suspended transport train 21 is positioned above the maintenance work support 23, the chain train 16 is operated to lower the transport train 21 and the maintenance work support 23 Transfer and support on. This makes it possible to safely and easily carry out maintenance work and the like on the transport train 21. However, in the case of hindering this work, remove the hanging cable 22 and move both carriages 1 </ b> A and 1 </ b> B away from the transport train 21. It is only necessary to move and retreat.
[0014]
When storing without using the maintenance work suspension frame composed of the two carts 1A and 1B integrally connected by the connecting members 12A and 12B, the two lateral connecting members 18A and 18B are connected to the connecting members 12A and 12B. At the same time, the connecting members 12A, 12B are removed from the two trolleys 1A, 1B by removing the bolt 13 connecting the connecting members 12A, 12B and the two trolleys 1A, 1B. As a result, the two carts 1A and 1B can be freely moved on the floor separately, so that the two carts 1A and 1B are fixed to the direction fixed wheels 5 as shown in FIGS. The short sides are connected in series so that the short sides are adjacent to each other so that a certain inside is located on the same side. In this state, the two carts 1A and 1B are connected and integrated with each other by two sets of direct connection means 24.
[0015]
Each of the direct connecting means 24 is connected to both ends of the flat bar 26 abutting over the outer surface near the lower end of the column member 9 at both ends of the short sides adjacent to each other of the both trucks 1A and 1B by bolts 25a and 25b, respectively. 1A and 1B, the flat bar 26 is not removed from both carts 1A and 1B when not in use, and the bolts 25a or 25b (or The non-removable support shaft) may be left attached to the fulcrum so as to be vertically swingable. Of course, the direct connection means 24 is not limited to the above, and may have any configuration such as a structure in which a hook mounted on one carriage is engaged with a locked portion provided on the other carriage. It may be something.
[0016]
In a state where the two carts 1A and 1B are connected and integrated with each other by the two sets of direct connecting means 24 as described above, the storage space 27A surrounded by the surrounding frame 3 above the cart unit 2 of each of the carts 1A and 1B. , 27B communicate with each other between the column members 9 at both ends of the short sides of the carriages 1A, 1B which are adjacent to each other because the respective side surfaces of the surrounding frame 3 are not closed by a plate material or the like. Therefore, as shown by phantom lines in FIG. 5, the two long connecting members 12A and 12B and the two lateral connecting members 18A and 18B straddle the storage spaces 27A and 27B of the two trucks 1A and 1B. Can be stored. In this case, it is desirable to store the carriages 1A, 1B connected in series so that the stored items do not protrude from the storage spaces 27A, 27B. Accordingly, the long connecting members 12A and 12B are stored diagonally across the storage spaces 27A and 27B in which the two trucks 1A and 1B are connected in series, as shown in the figure, and the middle part is adjacent to the two trucks 1A and 1B. It can be supported by the horizontal member 10. The lateral connecting members 18A and 18B can be placed directly on the bottom plate 7 of the bogie unit 2 of both the trucks 1A and 1B, but the lateral connecting members 18A and 18B are also similar to the connecting members 12A and 12B. Can be stored diagonally. In addition, the chain block 16 and the hanging cable 22 can be stored in the storage spaces 27A and 27B (on the bottom plate 7 of the bogie unit 2) of the bogies 1A and 1B.

Can be prevented. If a part of the long connecting members 12A, 12B and the like may protrude from the upper ends of the trolleys 1A, 1B (the upper ends of the storage spaces 27A, 27B), the entire periphery of the storage spaces 27A, 27B (the surrounding frame) 3 may be closed with a plate material or the like, and only the upper end may be opened so that the connecting members 12A and 12B can be stowed vertically. Also in this case, in order to facilitate the storage and removal of small items, an opening is provided in the lower half of the side surface of the surrounding frame 3 that is exposed to the outside when the bogies 1A and 1B are directly connected to each other. It is desirable to provide.
[0018]
As described above, all the accessories including the connection members 12A and 12B can be stored so as not to protrude from the storage spaces 27A and 27B of the two trolleys 1A and 1B connected in series. 4, it is easy to use the dustproof cover 28 that can cover the whole of the two trucks 1 </ b> A and 1 </ b> B connected in series, as indicated by phantom lines in FIGS. 4 to 6. As the dustproof cover 28 in this case, as shown in FIG. 7, for example, various front and back sides 29a and 29b, a back part 29c, and a top part 29d are opened with various dustproof cloths or plastic sheets. The left and right sides of the front cover portion 31 which is formed on the front edge of the top portion 29d and which are formed on the front body 29d of the cover main body 30 are fixed to the left and right side portions 29a and 29b by band fasteners (including band fasteners) 32a and 32b and buttons. It is preferable that the front edge can be freely closed and the front cover 31 is opened when the dustproof cover 28 is attached or detached so that the work can be easily performed. As shown, a pocket 33 for storing a work slip or the like can be provided on each outer surface around the dustproof cover 28 or on one or more selected outer surfaces.
[0019]
