  However, in the conventional elevator apparatus disclosed in Patent Document 1 described above, the work table is disposed below the elevator equipment, and therefore, when there is a hoistway fixing member or the like below the elevator equipment, The width is limited to the width of the storage space or less. For this reason, the width of the workbench is smaller than the width of the elevator equipment. Therefore, when checking the part of the elevator equipment outside the workbench, it is necessary for the worker to get out of the workbench and inspect it. Yes, with danger. Moreover, the part which does not reach from a work stand arises among the apparatuses for elevators, and inspection work cannot be performed with respect to this part. As described above, there is a problem that the safety and workability of the inspection work of the elevator equipment are low.

  The present invention has been made in view of such a state of the art, and an object of the present invention is to provide an elevator equipment inspection work table that can reliably perform inspection work on elevator equipment without causing danger. It is to provide.

  In order to achieve the above object, an elevator work inspection platform according to the present invention is provided at a lower end of an elevator equipment and fixed to a hoistway wall, and at one end of the fixed base. A work table that rotates around the fulcrum and a support that supports the work table perpendicularly to the fixed base. The elevator device is inspected on the work table, and the support is used when not in use. In the elevator work table for folding and storing the work table by removing the work table, the work table is composed of a base supported by the support column and a rectangular parallelepiped arranged above the base and facing the base And a rotating shaft that is provided between the base and the platform and rotatably supports the platform.

  In the present invention configured as described above, since the stepped base made of a rectangular parallelepiped can rotate around the rotation axis with respect to the base, the stepped base is rotated by rotating the step with respect to the base when the worktable is not used. By aligning the short side with the storage space, removing the support and folding the work table below the elevator device, the work table can be stored even when there is a hoistway fixing member or the like below the elevator device.

  At the time of inspection work in which the work table is used, a support is attached, the base is supported vertically with respect to the fixed base, the step is rotated with respect to the base, and the long side of the step is aligned with the elevator equipment. Can be made larger than the width of the elevator equipment. Thereby, it is possible to check the elevator equipment safely and reliably on the work table without the worker getting out of the work table. Thus, even if the width of the work table is limited to be equal to or less than the width of the storage space, it is possible to reliably perform the inspection work for the elevator equipment without any danger.

  The inspection work platform for elevator equipment according to the present invention is characterized in that the rotary shaft is provided by being shifted from the center of the platform. When comprised in this way, since the space | interval between the elevator apparatus and a step board can be made small when performing the inspection operation | work of an elevator apparatus, while being able to prevent an operator getting on the front from a workbench, Thus, it is possible to easily perform the inspection work of the elevator equipment from the work table.

  In the elevator work inspection platform according to the present invention, the work platform is provided between a base supported by a support column, a stepped base that is disposed above the base and is a rectangular parallelepiped facing the base, and the base and the stepped base. And a rotating shaft that rotatably supports the platform. During non-inspection work where the platform constructed in this way is not used, the platform is rotated with respect to the base so that the short side of the platform is aligned with the storage space. By rotating and aligning the long side of the platform with the elevator equipment, the lateral width of the platform can be made larger than the width of the elevator equipment when the elevator equipment is inspected when it can be folded and stored below the elevator equipment. it can. As a result, it is possible to perform the inspection work of the elevator equipment on the work table without the operator getting out of the work table, and to improve the safety and workability of the inspection work of the elevator equipment. it can.

FIG. 3 is a cross-sectional view showing a state in use of the first embodiment of the present invention along the line AA in FIG. 1, and FIG. 3 (a) shows the state when the phase of the platform is the same as the base. The figure shown, (b) figure is a figure which shows a state when a phase differs 90 degrees with respect to a base.

  As shown in FIG. 1, the elevator work inspection work platform according to the present invention is provided below the elevator equipment 2 attached to the wall in the elevator hoistway 1, and is arranged below the elevator equipment 2. The fixed base 3 that is fixed to the wall of the hoistway 1, the work table 15 that rotates around a fulcrum 10 provided at one end of the fixed base 3, and the work table 15 that is perpendicular to the fixed base 3. The support column 5 is supported.

  The work table 15 is disposed above the base 4 and the base 4 supported by the column 5, for example, the base 4 having one end of the column 5 engaged with the recess 20 of the fixed base 3 and the center supported by the other end. A step 6 made of a rectangular parallelepiped facing the base 4, for example, a step 6 made of a rectangular parallelepiped whose length of the short side is equal to the length of the short side of the base 4 and whose length of the long side is equal to the lateral width of the elevator device 2; A rotary shaft 8 provided between the base 4 and the platform 6 and rotatably supporting the platform 6, for example, is attached to the central upper surface of the base 4 and has a diameter larger than the rotation shaft 8 and a diameter larger than the width of the platform 6. And a rotating shaft 8 that rotatably supports the step 6 via a small disk 16.

  A pair of hooks 7 are attached to the back surface of the step 6 so as to face each other, and the step 6 is engaged with these hooks 7 so as to sandwich the disc 16 from the outside. Further, four stoppers 9a and 9b are alternately mounted around the rotary shaft 8 at equal intervals on the lower surface of the disc 16, and the pair of hooks 7 abut against the stoppers 9a and 9b, respectively, thereby causing the platform 6 The angle at which the motor rotates with respect to the base 4 is limited to 90 degrees or less. Note that one end of the column 5 is connected to the center of the base 4, and can be rotated around a fulcrum 11 at the center of the base 4.

  Here, for convenience, the state in which the longitudinal direction of the platform 6 and the longitudinal direction of the base 4 are parallel is in the same phase, and the state in which the longitudinal direction of the platform 6 and the longitudinal direction of the base 4 are orthogonal is 90 degrees different in phase. I will call it.

  As shown in FIG. 2, in the case of non-inspection work that does not use the first embodiment of the present invention, the column 5 is removed from the recess 20 of the fixed base 3 and the work table 15 is kept in phase with the elevator equipment 2. Folded downward and stored.

  In the case of inspection work using the first embodiment of the present invention, as shown in FIG. 1, first, the column 5 is engaged with the recess 20 of the fixed base 3 to support the work table 15 vertically with respect to the fixed base 3. To do. At this time, as shown in FIG. 3A, the hook 7 is in contact with the stopper 9a, and the work table 15 is in the same phase. Next, as shown in FIG. 3B, the step 6 is rotated 90 degrees with respect to the base 4. At this time, the hook 7 comes into contact with the stopper 9b located next to the stopper 9a, and the work table 15 is in a state where the phase is different by 90 degrees. In this state, the worker inspects the elevator equipment 2 from above the platform 6.

  According to the first embodiment of the present invention configured as described above, in the case of non-inspection work that does not use the work table 15, the work table 15 is rotated with respect to the base 4 so that the work table 15 has the same phase. Even if it is a narrow place where the fixing member of the hoistway 1 or the like is below the elevator equipment 2 by removing the support column 5 from the recess 20 of the fixed base 3 and folding the work table 15 below the elevator equipment 2. The work table 15 can be stored compactly.

  In the case of inspection work using the work table 15, the support column 5 is engaged with the recess 20 of the fixed base 3 to support the base 4 vertically with respect to the fixed base 3, and the step 6 is supported with respect to the base 4. By rotating the work table 15 so that the phase is 90 degrees different, the width of the platform 6 can be adjusted to the width of the elevator equipment 2. Accordingly, it is possible to check the elevator device 2 safely and reliably on the work table 15 without an operator getting out of the work table 15. Thus, even if the width of the work table 15 is limited to be less than or equal to the width of the storage space, the inspection of the elevator equipment 2 can be performed safely and reliably without any danger, and the inspection of the elevator equipment 2 can be performed. Work safety and workability can be improved.

  In the first embodiment of the present invention, the step 6 is engaged with the pair of hooks 7 so that the disc 16 is sandwiched from the outside, so that the step 6 does not come off the base 4 and the step 6 becomes the base 4. On the other hand, it can be rotated smoothly. Thereby, high structural stability of the work table 15 can be ensured.

  In the first embodiment of the present invention, the hook 7 of the step 6 abuts against the four stoppers 9 a and 9 b attached to the lower surface of the disc 16, so that the angle at which the step 6 rotates with respect to the base 4 is increased. Since it is limited to 90 degrees or less, it is easy to set the direction of rotation of the platform 6 with respect to the base 4, and the work table 15 can be easily set in the same phase or in a 90-degree different state. Further, the operator can easily grasp the state of the phase of the work table 15, which is convenient.

[Second Embodiment]
FIG. 4 is a cross-sectional view showing a state in use of the second embodiment of the present invention along the line AA in FIG. 1, and FIG. 4A shows a state when the phase of the platform is the same as that of the base. The figure shown, (b) figure is a figure which shows a state when a phase differs 90 degrees with respect to a base.

  As shown in FIG. 4, the second embodiment of the present invention is different from the first embodiment described above in that the rotation shaft 8 is shifted from the center of the platform 6, and other configurations are the first embodiment. The form is the same.

  According to the second embodiment of the present invention configured as described above, as shown in FIG. 4B, the interval between the elevator equipment 2 and the platform 6 is reduced in a state where the phase of the work table 15 is different. Therefore, it is possible to prevent the worker from getting out of the work table 15 and to easily check the elevator apparatus 2 from the work table 15.
