  As described above, the guide rails are provided on the left and right side frames constituting the frame, and the carriage is driven by engaging the wheel with the wheel interval fixed to the guide rail. Even if the transport carriage loaded with is moved along the guide rail, the distance between the left and right side frames is kept constant by the transport carriage with fixed wheel spacing. As a result, the distance between the side frames on both sides, in other words, the distance between the guide rails does not change, and it is possible to prevent the component parts from dropping from the side frames due to the wheel removal of the carriage.

  Hereinafter, the passenger conveyor repair method using the passenger conveyor component delivery method according to the present invention is based on the escalator repair method in which a new escalator is installed using the existing escalator frame shown in FIGS. explain.

  FIG. 3 shows the frame 1 after the components of the existing escalator have been removed. The existing frame 1 includes side frames 2A and 2B located on the left and right sides, and the heights of these side frames 2A and 2B. The lower cross beam 3 that connects the lower portions of the direction and the intermediate cross beam 4 that connects the intermediate portions in the height direction of the side frames 2A and 2B. Further, the side frames 2A and 2B respectively include an upper chord member 5A extending over the entire length in the longitudinal direction of the frame 1, a lower chord member 5B positioned at a distance from the upper chord member, and the upper chord member 5A and the lower chord member 5B. It is comprised with the connection material 6 which connects. In the frame 1 after removing most components, step upper rails 7A, 7B for guiding steps (not shown) are fixed to the intermediate cross beam 4, and the step lower rails 8A, 8B are It is fixed to the connecting member 6 of the side frames 2A and 2B via brackets 9A and 9B.

  By the frame 1 having such a configuration, the distance between the left and right side frames 2A and 2B is kept constant. However, when the new escalator frame is accommodated and supported in such an existing frame 1, the upper rails 7A and 7B for the steps, the intermediate cross beam 4, the lower rails 8A and 8B for the steps, and the brackets 9A and 9B. Becomes a hindrance and cannot accommodate a new frame.

  Therefore, as shown in FIG. 4, only the left and right side frames 2A and 2B and the lower cross girder 3 are left, and the others are removed to form the frame 1 in a U-shaped cross section. Thereafter, as shown in FIGS. 5 and 6, guide rails 10A and 10B are mounted on the upper chord material 5A of the left and right side frames 2A and 2B over the entire length thereof. The guide rails 10A and 10B have a triangular cross section with a vertex, and are fixed to a support seat 12 fixed on the mounting bracket 11 with fixing pieces 13A and 12B and bolts B2. The mounting bracket 11 has an inverted U shape that engages with the upper chord material 5A from above, and is fixed by the bolt B1.

  Next, a transport carriage 14 as shown in FIGS. 1, 2, 7 and 8 is caused to travel on the guide rails 10A and 10B fixed on the left and right side frames 2A and 2B. The carriage 14 includes two sets of wheels 15 and 16 including a pair of left and right wheels 15A and 15B and wheels 16A and 16B, and wheel seats 17A and 17B that pivotally support the wheels 15A and 15B and the wheels 16A and 16B, respectively. The side members 18A and 18B for connecting the wheel seats 17A and 17B in the direction along the guide rails 10A and 10B, the connecting member 19 for connecting the side members 18A and 18B, and the side members 18A and 18B stand up. Main columns 20A, 20B to be installed, movable columns 21A, 21B extending from the main columns 20A, 20B, and an elevating mechanism 22 for moving the movable columns 21A, 21B up and down relative to the main columns 20A, 20B; The suspension beam 23 straddling between the movable columns 21A and 21B, and a weighting device 24 such as a chain block provided on the suspension beam 23 are provided. The two sets of wheels 15 (15A, 15B), 16 (16A, 16B) have triangular concave grooves that match the guide rails 10A, 10B having a triangular cross section. The distance between the pair of left and right wheels 15A and 15B and the distance between the wheels 16A and 16B is set so that the wheels 15 and 16 of each set have the same distance as the distance between the guide rails 10A and 10B. 23 so as not to change.

  The elevating mechanism 22 has a protrusion projecting outside the main pillars 20A and 20B on at least one of the movable pillars 21A and 21B accommodated inside the hollow main pillars 20A and 20B. An endless chain extending in the longitudinal direction of the main pillars 20A and 20B is connected to the protrusion, and the movable pillar is driven in one direction by a ratchet mechanism that fixes the chain to the main pillar. It is made to protrude upward from. When the protruding movable column is accommodated in the main column, by releasing the ratchet mechanism, the movable column can be lowered by its own weight and accommodated in the main column.

  The wheel 15A and the wheels 16A and 16B are engaged with the left and right guide rails 10A and 10B installed on the side frames 2A and 2B of the existing frame 1 with the transport cart 14 configured as described above. By making it drive | work, the change of the space | interval of the left and right side frames 2A and 2B is prevented by the transport carriage 14. Therefore, it is possible to prevent the carriage 14 from being removed from the guide rails 10A and 10B. The distance between the pair of left and right wheels 15A and 15B and the wheels 16A and 16B is constant depending on the axle that supports the wheels 15A and 15B coaxially and the axle that supports the wheels 16A and 16B coaxially. You may make it fix to.

  Further, on the side of the upper floor UF of the side members 18A and 18B of the transport carriage 14, a traction rope 25 is connected to a connecting member 19 that is attached when components are conveyed, and this traction rope 25 is installed on the upper floor UF. The transport carriage 14 is moved up and down along the guide rails 10A and 10B by winding and rewinding with the driving means 26 such as the winch. When the transport carriage 14 is in the horizontal section of the guide rails 10 </ b> A and 10 </ b> B, an operator can easily move the transport carriage 14 by pushing the transport carriage 14. However, when the transport carriage 14 is in the inclined section of the guide rails 10A and 10B, it is safe to raise and lower the transport carriage 14 using the braking mechanism received by the tow rope 25, the drive means 26, and also the drive means 26. Can be carried.

  Next, one or a plurality of transport carts 14 configured as described above are connected to run on the guide rails 10A and 10B, and a floor on which new escalator components are installed, for example, the upper floor Move to the floor UF side, adjust the height of the suspension beam 23 by the lifting mechanism 22 and operate the hoisting device 24 to lift the components 27 such as the divided frame of the new escalator to the transport carriage 14, As shown in FIG. 1, it moves to the accommodation place of the existing frame 1. When the transport carriage 14 is moved to the accommodation place, the elevating mechanism 22 and the hoisting device 24 are operated to lower the component 27 and temporarily fix it. Such operations are repeated to temporarily fix the new escalator components at the necessary locations, and then integrate the components to install and complete the new escalator frame in the existing frame 1. After that, other components of the new escalator are carried in and assembled using the transport carriage 14, and finally the transport carriage 14 and the guide rails 10A and 10B are withdrawn, and then a balustrade member is set up on the side frame of the new escalator. Set up and complete a new escalator.

  By the way, when two or more transport carts 14 are used in the present embodiment, a rope or a bar having a universal joint is used so that the distance between the two transport carts 14 and 14 is constant. By connecting and moving with the connecting member 28, the two transport carriages 14 and 14 can be stably driven.

  As described above, according to the present embodiment, even if the transport carriage 14 is driven using the side frames 2A and 2B constituting the existing frame 1, the guide rails 10A and 10B are engaged. Since the wheels 15A, 15B, 16A, 16B and the components of the transport carriage 14 can prevent the deformation of the side frames 2A, 2B, in particular, the change in the distance between the upper chord members 5A, 5B, the transport carriage 14 can be removed from the guide rails 10A, 10B. It is possible to safely carry in the components without removing the wheel.

  By the way, the present embodiment describes a method for repairing a passenger conveyor using a method for carrying in components of a passenger conveyor, but the present invention can also be used when carrying out components of an existing escalator. Needless to say.

  That is, when carrying out the components of the existing escalator, as shown in FIG. 3, after removing the balustrade members located on the upper chord members 5A and 5B, the guide rail 10A is placed on the upper chord members 5A and 5B. , 10B is attached and the transport cart 14 is caused to travel. In this state, the components of the existing escalator, for example, the drive motor, the control panel, or the structural members of the frame body are removed as they are or separated and the transport cart 14 is removed. And is carried out of the existing frame 1. Even during such unloading work, the wheel 15A, 15B, 16A, 16B of the transport carriage 14 and the constituent members of the transport carriage 14 can prevent the distance between the side frames 2A, 2B from being deformed. , 10B, and the components can be safely carried out. Thus, after carrying out the components of the existing escalator using the transport carriage 14, the escalator can be repaired efficiently by carrying in the new components of the escalator using the same transport cart 14. Can do.

  In each of the above explanations, the laying range of the guide rails 10A and 10B is the range of the upper chord members 5A and 5B of the side frames 2A and 2B, but as in the second embodiment shown in FIG. By extending the guide rails 10A and 10B beyond the upper chord members 5A and 5B to the upper floor UF and / or the lower floor LF, the transport carriage 14 is moved to the upper floor UF and / or the lower floor LF. As a result, the components can be loaded and unloaded onto the transport carriage 14 in a wide space of the upper floor UF and / or the lower floor LF, so that the loading and unloading work can be performed safely.

  In addition, the guide rails 10A and 10B have a triangular cross section having apexes, and the wheels 15 (15A and 15B) and 16 (16A and 16B) have a triangular shape matching the guide rails 10A and 10B having a triangular cross section. However, it is not particularly limited to this kind of cross-sectional shape. For example, when the guide rails 10A and 10B are square cross-sections or circular cross-sections, the grooves corresponding to those cross-sectional shapes are provided. If the guide rails 10A and 10B have a concave cross section, the wheels 15 (15A and 15B) having a cross section that engages with the concave cross section. , 16 (16A, 16B).

  In the above description, the dedicated guide rails 10A and 10B are attached to the upper chord members 5A and 5B, and the transport carriage 14 is caused to travel. However, if there are no obstacles on the top surfaces of the upper chord members 5A and 5B, the upper chord members 5A and 5B themselves may be used as the guide rails 10A and 10B. In this case, the dedicated guide rails 10A and 10B may be omitted. it can.

  In addition, when the new escalator is installed at the new installation location, the left and right side frames of the new escalator can be used as guide rails, or guide rails can be installed on the left and right side frames, respectively. The truck can be run and loaded with new escalator components and transported to the required part of the frame.
