In the figure, 1 is the elevator hoistway, 2 is the wall of the hoistway 1, 3 is the floor floor position of the lowest floor (not shown) of the building in the hoistway 1, 4 is the floor floor located on the wall 2 Elevator equipment 5 consisting of a control panel arranged slightly above position 3 is a bracket mounted on the wall 2 which forms the main part of the wall 2 of the hoistway 1 and is separated from each other in the horizontal direction. 2 and located below the landing floor surface position 3. A base plate 6 is disposed between the brackets 5, and one side is pivotally attached to the wall 2 side, that is, near the upper end of the bracket 5, and is normally disposed at a retracted position along the wall 2 surface.
[0008]
Reference numeral 7 denotes a holding mechanism. One end of the first member 8 is pivotally attached to the wall 2 side, that is, near the lower end of the bracket 5, and one end is pivotally attached to the rotating end of the base plate 6. The second member 9 pivotally attached to the rotation end, and both the first member 8 and the second member 9 are engaged with each other in a state where they are arranged in a straight line when necessary, thereby preventing relative rotation displacement between the two members. It is comprised by the blocking piece 10 to do. Both of the above are arranged in a straight line in a state where the base plate 6 is placed in a horizontal position, and prevent the base plate 6 from rotating downward.
[0009]
Reference numeral 11 denotes a telescopic ladder, which is slidable on a plurality of trap members 12 formed in a U-shape, and a drawing on both sides of the U-shape of another adjacent trap member 12 provided on the upper end of the U-shape of the trap member 12. The sliding engagement piece 13 which is engaged with the hanger and prevented from deviating at the lower end of the drawing, and a binding tool such as a metal fitting which binds the plurality of trap members 12 in a superposed state (not shown). Yes. The upper end of the trap member 12 at the uppermost stage of the telescopic ladder member 11 is pivotally attached to the rotating end of the base plate 6.
[0010]
Reference numeral 14 denotes a fitting cylinder, which is fixed to both sides of the rotating end of the base plate 6 and is provided with a fitting hole in which the center line is arranged in the vertical direction in the state shown in FIG. Reference numeral 15 denotes a handrail for work. When the maintenance work is performed, that is, the base plate 6 is arranged in a horizontal position, the lower end portion is fitted to the fitting cylinder 14 by an artificial operation, and the rotation end of the base plate 6 is fitted. Established.
[0011]
In the elevator work table apparatus configured as described above, an elevator work table apparatus mainly including the bracket 5, the base plate 6, the holding mechanism 7, and the telescopic ladder 11 is provided near the lower portion of the hoistway 1. And normally, the base plate 6 is arrange | positioned in the retraction position along the wall 2 surface of the hoistway 1.
[0012]
In addition, the telescopic ladder 11 is shortened by binding a plurality of trap members 12 in a superposed state to each other by a binding tool at a normal time, and is disposed at a position along the wall 2 surface of the hoistway 1. As a result, the elevator work table device is held in the retracted state as shown in FIG. And an elevator is normally drive | operated without trouble in the state shown in FIG.
[0013]
Then, at the time of maintenance work for the elevator equipment provided near the lower part in the hoistway 1, the elevator work table device is arranged at the work position as described below. That is, the rotating end of the base plate 6 is lifted from the state shown in FIG. 3, and the base plate 6 is arranged in the working position, that is, the horizontal position as shown in FIG. 6 through the state shown in FIG. In this state, both the first member 8 and the second member 9 of the holding mechanism 7 are arranged in a straight line, the refraction displacement of both is blocked by the blocking piece 10, and the base plate 6 is held in the horizontal position.
[0014]
Next, the telescopic ladder 11 is extended to a suspended state by releasing the binding of the plurality of trap members 12 by the binding tool. Further, the work handrail 15 is fitted into the fitting hole of the fitting cylinder 14 and is erected at the end portion on the rotating side of the base plate 6. As a result, the base plate 6 is held in a horizontal position, the telescopic ladder 11 is extended in a suspended state, and the work handrail 15 is erected on the base plate 6 to be in the state shown in FIG. Maintenance work of equipment such as the control panel 4 near the lower part in the hoistway 1 is performed.
[0015]
In the elevator work table apparatus configured as described above, it is not necessary to carry the ladder stored outside and carry it into the hoistway 1 during maintenance work on the lower part of the equipment in the hoistway 1. Become. In addition, maintenance and inspection of equipment near the lower part in the hoistway 1 can be performed by work from the base plate 6 held in a horizontal position.
[0016]
Thereby, maintenance work can be easily performed and work efficiency can be improved. In addition, since the telescopic ladder 11 is provided to hang down from the base plate 6, it is possible to easily cope with the difference in the pit depth of the hoistway 1 in the elevator. Therefore, it is not necessary to manufacture the telescopic ladder 11 corresponding to the pit depth for each elevator, and the productivity of the elevator work table apparatus can be improved.
