Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applicable to the removal of equipment installed in an elevator hoistway,
This relates to work equipment during new installation work.

<Prior Art> Conventionally, there is a device of this type described in Japanese Utility Model Application Publication No. 52-14673. Figures 3 and 4 are explanatory diagrams showing this conventional device, with Figure 3 being a front view and Figure 4 being a side view of the main parts. supporting frame 2
Place the apron 3 around the support shaft 4, for example, 2 in Fig. 4.
The apron 3 is formed so that it can rotate 90 degrees from the position shown by the dotted chain line to the position shown by the solid line, and one end of the apron 3 is fixed to the ball floor 5 with bolts, etc., and the worker rides on this apron 3 to move up and down the elevator passageway (Fig. The plan is to remove the desired equipment (not shown) and install new equipment. Incidentally, while the passenger car 1 is being raised and lowered, the apron 3 is released from being fixed to the hall floor 5, rotates 90 degrees, and is fixed to the lower part of the passenger car 1.

Problems to be Solved> In conventional work, one end of the apron 3 is fixed to the pole floor 5, so it is impossible to work in this fixed position, and when moving the work position, the above-mentioned method is required. The apron 3 has to be unfixed and moved, and the apron 3 has to be fixed to another pole floor 5, and it takes time to fix and release the apron 3, and it is not always possible to secure the optimum working position, which reduces work efficiency. It was bad.

In addition, since the length of the nib t-contact 3 is limited, the working posture of the apron 3 cannot be adjusted to a sufficient height, as shown in Fig. 3. Because they were in a squatting position and the working space was small, they were prone to fatigue during long hours of work.

That is, the above-mentioned prior art is designed for continuous movement work and work posture.

First, there was a problem of lowering work efficiency, and one problem was that it did not promote worker fatigue.

SUMMARY OF THE INVENTION In view of the problems of the prior art described above, an object of the present invention is to provide an elevator working device that can secure a wide working range and improve work efficiency by reducing worker fatigue. It is.

Means for Solving the Problems In order to achieve the above object, the present invention provides a working device for an elevator that performs the removal and new installation of equipment installed in the hoistway of an elevator having a car. At least the lower part of the car is provided with a work floor that is raised and lowered integrally with the raising and lowering of the car.

As mentioned above, the present invention provides a working floor at least below the car that can be raised and lowered integrally with the raising and lowering of the car. There is no need to fix it to the floor or release it, and the work position can be secured at any position on the hoistway.

The working floor is large enough to allow the elevator to be raised and lowered, and for example, it can be provided with enough space to allow workers to work in a standing position, ensuring a wide working range. can.

・ζ′ Embodiment> The elevator working device of the present invention will be described below with reference to FIG.

FIG. 1 is a front view showing a first embodiment of the present invention.

In the figure, 1 is a board similar to that shown in Figure 3;
6 is a hoistway in which this car 1 is arranged so that it can be raised and lowered;
Although not shown in the drawings, the hoistway 6 is provided with in-tower wiring and various types of equipment. 7 is provided at the bottom of the car 1,
This work floor is raised and lowered integrally with the east car 1, and a support frame 8 forming the upper part thereof is removable from the lower frame 0 of the car 1 via bolts. For example, as shown in FIG. 1, this work floor 7 is set to have a height dimension that provides a sufficiently large work space that allows a worker to work in a standing position. In addition, 10 is a handrail provided on this fl-leaf body 7, and 11 is an operation panel that is attached to this handrail 1O and can control the elevation and descent of the car 1, for example.

In the embodiment of FIG. 1 configured in this way, for example,
When removing equipment or installing new equipment in the hoistway 6 in a building with 1st to 8th floors, the working floor 7 shall be provided at the bottom of the car 1 during the normal usage hours of this building. Therefore, the first floor landing will not be used and the elevator will operate normally between 2 and 8 Wj. Then, at night or on closed days, a worker gets on the work floor 7 and operates the operation panel 11 to remove or install a desired piece of equipment in the hoistway 6.

According to this embodiment, the work floor 7 moves up and down integrally with the car 1, so that the work floor 5 and the car 1 are placed on the hall floor or the like.
Excellent work efficiency can be achieved because desired equipment, etc. can be removed or new installation work can be carried out at any lifting/lowering position of the car without the need for work to fix the car. Since the space is set to be large enough to allow workers to work in a standing position, a wide working range can be secured, which also increases work efficiency. Furthermore, since a sufficient amount of space can be secured in this way, the movement of the worker's body is not restricted so much, and the fatigue of the worker can be reduced.

In addition, since the work floor 7 is provided at the bottom of the car 1,
Work in the pit in the lower part of the hoistway 6 can also be carried out easily.

In addition, since the working floor 7 is provided at the bottom of the car as mentioned above, during normal use of the building, the working floor 7 is
Elevators on the 8th floor can be operated, and desired removal and new construction work can be carried out on days when the building is closed or at night, with little inconvenience to the traffic of people in the building.

Further, since the operation panel 11 is attached to the handrail 10, a worker on the work floor 7 can perform the desired work while controlling the elevation and descent of the platform 1, which also improves work efficiency.

FIG. 2 is a front view showing a second embodiment of the invention.

In this second embodiment, a work floor 7 is provided at the bottom of the car 1, and another work floor 12 is provided at the top of the car 1.

According to this embodiment, equipment located on one side of the hoistway 6 and the like can be easily removed and new equipment installed.

In addition, if this second embodiment is applied to a building having 1st to 8th floors, normal operation can be performed between the 2nd to 7th floors during normal use of the building, and the desired removal can be carried out on days when the building is closed. ,
New construction work can be carried out, and therefore these σ) removal and new construction works can be carried out with little inconvenience to the people in the building.

<Effects of the Invention> According to the present invention, since the work floor can be raised and lowered together with the car, there is no need to fix the work floor, and equipment, etc. in the hoistway can be removed and new work positions can be moved freely. Since it can be moved continuously to the ascending and descending position and sufficient work floor space can be secured, work efficiency is significantly improved during elevator removal and new installation work, and the fatigue of workers is reduced. is possible.
