As shown in FIG. 5, the fixing surface portion 21 is placed on the upper surface portion 121a of the upper beam 121, and is fastened and fixed to the upper beam 121 via a fixing bolt 61. A support surface portion 22 is formed continuously at one end of the fixed surface portion 21 substantially vertically.
[0030]
　The support surface portion 22 is bent substantially vertically from one end of the fixed surface portion 21 toward the upper side in the vertical direction. The support surface portion 22 is provided with a fastening portion 22a into which the support bolt 62 is screwed. As shown in FIG. 5, the support pillar 31 of the work floor assembly 15, which will be described later, is fastened and fixed to the support surface portion 22 via the support bolt 62. Further, a reinforcing surface portion 25 is provided at a corner portion between the fixed surface portion 21 and the support surface portion 22 so as to connect the fixed surface portion 21 and the support surface portion 22.
[0031]
　A regulation plate 23 is provided at the other end of the fixed surface 21 opposite to the one end where the support surface 22 is provided. The regulation plate 23 is bent substantially vertically downward in the vertical direction from the end portion of the fixed surface portion 21 opposite to the end portion on which the reinforcing surface portion 25 is provided. When the fixed surface portion 21 is placed on the upper beam 121 on the upper surface portion 121a, the regulation plate 23 is inserted into the accommodation recess 131a of the accommodation member 131.
[0032]
　Further, a protective cover 24 is attached to the other end of the fixed surface portion 21 by a fixing screw 28. The protective cover 24 protrudes from the other end of the fixed surface portion 21 by a predetermined length, and the tip portion is bent downward in the vertical direction. When the fixed surface portion 21 is placed on the upper beam portion 121 on the upper surface portion 121a, the protective cover 24 covers the upper part of the switch 136 of the stop device 130 in the vertical direction.
[0033]
　Further, as shown in FIGS. 3 and 4, the second connecting member 12 has a fixed surface portion 21 and a supporting surface portion 22 like the first connecting member 11. The second connecting member 12 has a configuration in which the regulation plate 23 and the protective cover 24 are removed from the first connecting member 11, and the other configurations are the same, so the description thereof will be omitted.
[0034]
　Next, the work floor assembly 15 will be described.
　FIG. 8 is a side view showing a state in which the work floor assembly 15 is folded.
[0035]
　As shown in FIGS. 3 to 5, the work floor assembly 15 has two support columns 31, 31 and a base portion 32, and a floor member 34. The two support columns 31, 31 are fixed to the first connecting member 11 or the second connecting member 12 via the support bolts 62. Further, as shown in FIG. 5, the lower end portion of the support column 31 in the vertical direction is fastened and fixed to the side surface portion 121c of the upper beam 121 via a fixing bolt 63.
[0036]
　Further, as shown in FIG. 3, the reinforcing member 52 is fixed so as to connect the two support columns 31 and 31. Further, as shown in FIG. 5, a locking portion 31a is formed on the support column 31. The locking portion 31a is formed by cutting out an end portion on the side opposite to the upper beam 121 at the lower end portion in the vertical direction of the support column 31.
[0037]
　A rotating shaft 36 is attached to the upper end of the support column 31 in the vertical direction. The base portion 32 is rotatably supported by the rotating shaft 36. Therefore, the two support columns 31, 31 and the base portion 32 are connected via the rotation shaft 36.
[0038]
　As shown in FIG. 8, by rotating the two support columns 31 and 31 around the rotation shaft 36, the two support columns 31 and 31 and the base portion 32 overlap each other. As a result, the work floor assembly 15 can be folded into a small size, and the work floor assembly 15 can be easily transported. Further, the space for storing the work floor assembly 15 can be reduced.
[0039]
　The base portion 32 is formed in a substantially flat plate shape. A plurality of openings 32a are formed on one surface of the base portion 32. As a result, the weight of the work floor assembly 15 can be reduced. A support 37 is rotatably attached to the side surface of the base 32.
[0040]
　The support 37 is formed by bending a rod-shaped member. A rotating pin 37a is provided at one end of the support 37. The rotation pin 37a is rotatably supported by the side surface portion of the base portion 32. Further, after the work floor assembly 15 is unfolded, a locking piece 37b is provided at the other end of the support 37 opposite to one end. The locking piece 37b is detachably locked to the locking portion 31a. Therefore, the support 37 is interposed between the base portion 32 and the support pillar 31.
[0041]
　Further, as shown in FIG. 3, a floor member 34 is placed on one surface of the base portion 32. The floor member 34 is formed in a rectangular flat plate shape. A skirting board 34a is formed on the peripheral edge of the floor member 34. The skirting board 34a is bent substantially vertically from the peripheral edge portion of the floor member 34 toward the upper side in the vertical direction.
[0042]
　In this example, an example in which the skirting board 34a is provided on the floor member 34 has been described, but the present invention is not limited to this, and the skirting board may be provided on the base portion 32, or the skirting board may be provided on the base portion 32. Or the floor member 34 may be configured as a separate member.
[0043]
　Further, the reinforcing member 51 is fixed to the other surface of the base portion 32 on the side opposite to the one surface on which the floor member 34 is provided. The strength of the base portion 32 is increased by the reinforcing member 51.
[0044]
　A fall prevention book 16 is detachably attached to the base portion 32. The fall prevention book 16 has four legs 41, a handrail 42, and a fixing member 43. The four legs 41 are fixed to the four corners of the base 32 via fixing members 43. A handrail 42 is attached to the upper end of the leg 41 in the vertical direction via a fixing screw 64. The handrail 42 is attached to three sides except one side of the hall 301 side (see FIG. 4) of the building structure where the worker enters and exits. The handrail 42 ensures the safety of the operator during maintenance and inspection.
[0045]
　The configuration of the work floor assembly 15 and the fall prevention book 16 is not limited to the above-mentioned example, and various other configurations can be applied. For example, a chain, a rope, or the like may be used as the handrail 42 of the fall prevention book 16. Further, the base portion 32 and the floor member 34 of the work floor assembly 15 may be configured by a plurality of members, or the base portion 32 may be configured to be foldable in half.
[0046]
2. 2. Example of installation work of workbench for elevator
　Next, an example of installation work of workbench 10 having the above-described configuration will be described.
　First, as shown in FIG. 1, the car 120 is raised to the vicinity of the maintenance target device 150. As a result, as shown in FIGS. 3 and 4, one end of the lock member 132 in the stop device 130 faces the regulation hole 201a provided in the car side guide rail 201. Then, as the lock member 132 slides along its axial direction, one end of the lock member 132 is removably inserted into the regulation hole 201a. As a result, the ascending / descending movement of the car 120 can be mechanically regulated by the stop device 130.
[0047]
　Further, when the lock member 132 slides and moves and is inserted into the regulation hole 201a, the switch 136 outputs a stop signal to a control unit (not shown). As a result, the control unit stops the drive of the hoisting machine. As a result, the ascending / descending movement of the car 120 is electrically regulated by the stop device 130. As a result, it is possible to prevent the car 120 from moving up and down against the intention of the operator during maintenance and inspection, and it is possible to ensure safety during maintenance and inspection.
[0048]
　Next, the fixed surface portion 21 of the first connecting member 11 and the second connecting member 12 of the workbench 10 is placed on the upper surface portion 121a of the upper beam 121. At this time, the regulation plate 23 of the first connecting member 11 is inserted into the accommodating recess 131a of the accommodating member 131. The regulation plate 23 faces the other end of the lock member 132. Next, the first connecting member 11 and the second connecting member 12 are fastened and fixed to the upper beam 121 by the fixing bolt 61. In this way, by fixing the first connecting member 11 and the second connecting member 12 to the upper beam 121, which has relatively high strength in the car 120, the workbench 10 can be stably installed.
[0049]
　As shown in FIG. 2, when the lock member 132 of the stop device 130 is not inserted into the regulation hole 201a, the other end of the lock member 132 is accommodated in the accommodating recess 131a. Therefore, since the regulation plate 23 of the first connecting member 11 and the lock member 132 interfere with each other, the first connecting member 11 cannot be fixed to the upper beam 121.
[0050]
　That is, the first connecting member 11 cannot be fixed when the stop device 130 is activated and safety is not ensured. Then, as shown in FIGS. 3 and 4, the first connecting member 11 can be fixed and the workbench 10 can be installed only when the stop device 130 is operated and safety is ensured.
[0051]
　Further, when the first connecting member 11 is placed on the upper beam 121, the protective cover 24 covers the upper part of the switch 136 of the stop device 130 in the vertical direction. As a result, the protective cover 24 can prevent the operator from accidentally stepping on the switch 136 during maintenance and inspection, and can prevent the switch 136 from being damaged.
[0052]
　Next, the work floor assembly 15 is unfolded to lock the locking piece 37b of the support 37 to the locking portion of the support pillar 31. As a result, since the support body 37 is interposed between the base portion 32 and the support pillar 31, it is possible to prevent the base portion 32 from rotating toward the support pillar 31 around the rotation shaft 36. As a result, it is possible to prevent the work floor assembly 15 from being folded against the intention of the operator during maintenance and inspection, and it is possible to improve work safety.
[0053]
　Then, the two support columns 31 and 31 are fastened and fixed to the first connecting member 11 and the second connecting member 12 by the support bolts 62. Further, as shown in FIG. 5, the lower end portion of the support column 31 is fastened and fixed to the side surface portion 121c of the upper beam 121 via the fixing bolt 63.
[0054]
　The locking operation of the support 37 may be performed after fixing the two support columns 31, 31 to the first connecting member 11, the second connecting member 12, and the upper beam 121.
[0055]
　Next, the floor member 34 is placed and attached to one surface of the base portion 32. Further, the four legs 41 of the fall prevention book 16 are erected at the four corners of the base portion 32. Then, the leg portion 41 is fixed to the base portion 32 by the fixing member 43. Next, the handrail 42 is attached to the upper end of the leg 41 using the fixing screw 64. As a result, the installation work of the workbench 10 is completed.
[0056]
　Further, since the restricting plate 23 faces the other end of the lock member 132, the movement of the lock member 132 toward the other end in the axial direction is restricted. Therefore, when the first connecting member 11 is placed on the upper beam 121, the lock member 132 cannot be pulled out from the regulation hole 201a. That is, the regulation plate 23 regulates the operation of the stop device 130 in the direction of releasing the restriction on the ascending / descending movement of the car 120. As a result, during maintenance and inspection, the restriction on the vertical movement of the car 120 in the stop device 130 is not lifted, so that the safety during maintenance and inspection can be improved.
[0057]
　Further, the stop device 130 cannot release the restriction on the vertical movement of the car 120 until the first connecting member 11 is removed from the upper beam 121 and the regulation plate 23 comes out of the accommodating recess 131a. In this way, since the stop device 130 is not released until the workbench 10 is removed from the car 120, the workbench 10 can be safely removed.
[0058]
　As described above, the workbench 10 cannot install the car 120 until the stop device 130 is activated. As a result, the workbench 10 cannot be installed in the car 120 during normal operation other than maintenance and inspection, so that the weight of the car 120 can be reduced.
[0059]
　The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the gist of the invention described in the claims. In the above-described embodiment, the example in which the regulation plate 23 and the protective cover 24 are provided only on the first connecting member 11 has been described, but the present invention is not limited to this, and the regulation plate 23 is also provided on the second connecting member 12. And the protective cover 24 may be provided.
[0060]
　For example, when the maintenance target device 150 is installed in the hoistway 110 on the other end side of the upper beam 121 in the longitudinal direction in the car 120, the second connecting member 12 is the other end portion of the upper beam 121 in the longitudinal direction. Is fixed to. Then, the regulation plate 23 provided on the second connecting member 12 is inserted into the accommodating recess of the stop device arranged at the other end of the upper beam 121 in the longitudinal direction.
[0061]
　Moreover, it is not limited to this. The regulation hole 201a into which the lock member 132 is removably inserted is not limited to that provided in the car side guide rail 201. A regulation hole may be formed in a member different from the car-side guide rail 201 provided in the hoistway 110, for example, a rail bracket or a weight-side guide rail that slidably supports a balance weight.
[0062]
　Although words such as "parallel" and "orthogonal" have been used in the present specification, these do not mean only strict "parallel" and "orthogonal", but include "parallel" and "orthogonal". Further, it may be in a "substantially parallel" or "substantially orthogonal" state within a range in which the function can be exhibited.
