A drive wiring 22 has one end connected to the control panel 13 and the other end connected to the hoisting machine 7 via the wiring duct 17. Although not shown, a power supply line is drawn in from the outside and connected to the control panel 13.

[0006] In the elevator as described above, each device is regularly maintained and inspected to maintain required functions. In order to improve the performance of the elevator, renovation work using the latest electronic technology will be carried out with the aim of saving power and improving ride comfort compared to the existing elevator. In such repair work, an existing device is used for some devices, and work is performed to replace other devices, mainly control devices, with updated devices.

[0007]

In the repair work in which existing equipment is used for some of the equipment described above and other equipment is updated, the power supply is cut off and the existing equipment that is updated first is sequentially removed. Work is performed. Next, an operation of attaching the updated device to the location of the removed existing device is performed. However, there are the following problems in removing and updating such devices.

That is, in general, the update hoisting machine and the update control panel are different from the existing products corresponding to the external dimensions and the positions where the wiring is drawn in. Therefore, it is necessary to change the position of the existing wiring duct 17. For this reason, for example, the work of removing the wiring duct 17 on the floor 3 of the machine room 2 and installing the renewal wiring duct in its place is complicated and requires a long time. Also,
A lot of labor and a long time are required for storing the updated hoistway wiring and the updated moving cable in the existing wiring duct 17 and for fixing the updated hoistway cable to the wall of the hoistway 1.

[0009] Generally, the renewal moving cable is carried to a construction site in a state of being wound around a drum. For this reason, the basket 11 has a winding habit immediately after being pulled out of the drum.
When the is moved up and down, the curved portion swings complicatedly near the fixed portion to the wall of the hoistway 1, and there is a problem that the update moving cable contacts the equipment of the hoistway 1. Therefore, it is necessary to stop the curving portion of the renewal moving cable in the vertical state for a predetermined time after the suspension work and remove the curl.

[0010] Due to the above-mentioned reasons, work noise is generated, dust such as waste concrete is generated, and repair work for carrying out waste equipment takes a long time. For this reason, the user of the building where the elevator is installed is hindered from being calm, and the benefit of the user of the elevator is impaired due to long-term suspension of the elevator due to prolonged repair work.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem. In the first half of the repair work, the elevator can be used depending on the time zone, and in the latter half of the repair work, the elevator can be stopped for a shorter period of time. The purpose is to obtain a renovation method.

[0012]

In the repair method for an elevator according to the present invention, the first step of suspending the operation of the elevator at a predetermined time throughout the day and mounting the renewal equipment at an approximate position of the existing equipment; A later step of suspending the operation of the elevator for a longer time than the work, removing the existing equipment, and installing the update equipment at the existing equipment position is performed.

[0013] In the elevator repair method according to the present invention, the renewal wiring duct is mounted at an approximate position of the existing wiring duct in the elevator machine room in the first step.

In the elevator repair method according to the present invention, the renewal moving cable is disposed at an approximate position of the existing moving cable suspended from the machine room of the elevator in the first half of the process, and one of the steps of ascending and descending the elevator car is performed. At the position above the / 2 position, the update moving cable is fixed to the hoistway wall of the elevator by the update fixture, and the lower end is suspended for a predetermined time.

Further, in the elevator repair method according to the present invention, in the first step, the updated hoistway wiring is installed at an approximate position of the existing hoistway wiring wired from the machine room of the elevator to the hoistway.

2 is removed, the update drive wiring 37 is connected to the update control panel 25 by a connector, and connected to the update hoisting machine 27 by a connector 38. Although illustration is omitted,
A power supply line is drawn in from the outside and connected to the update control panel 25.

As described above, firstly, the operation of the elevator is suspended at a predetermined time throughout the day, and the work of the first step of performing the regular work of mounting the update equipment at the approximate position of the existing equipment is performed. For example, the operation of the elevator is paused for several hours in the daytime zone of the day to perform a periodic work. For this reason, the elevator can be used when commuting to work in the morning and evening, and the benefits of the elevator user can be secured.

The wires such as the renewal moving cable 30 and the existing hoistway wiring 18 are adjusted to a required length as a bundle of wires at a factory, and a connector is provided at an end. For this reason, the number of operations at the repair work site is reduced, so that the man-hours of the first-stage process are reduced and the period can be shortened. Next, on the whole day, the operation of the elevator was suspended for a longer time than the work of the above-mentioned first step, the existing equipment was removed, the update equipment was installed at the existing equipment position, and the electrical connection of the update equipment was performed. The work of the latter stage in which the whole-day work of performing the above is performed is performed.

In the first step, an elevator can be used depending on the time zone, and the period of the second step in which work is performed all day can be shortened. As a result, it is possible to reduce the cost of the repair work of the elevator, and also to shorten the entire elevator downtime in the repair work. For this reason, the inconvenience of the user of the elevator can be reduced. In addition, work noise is generated, dust such as waste concrete is generated, and the period of the repair work for carrying out the waste equipment is shortened. Therefore, the period during which the environment of the building in which the elevator is installed is reduced can be reduced.

Further, in the first step, the tip side of the update moving cable 30 is once suspended and arranged in a stationary state to remove the curl. Thereby, the update moving cable 30
The stabilization of the dynamic characteristic of the elevator causes the update moving cable 30 to swing in a complicated manner due to the elevation of the car 11 when the operation of the elevator is resumed, and the occurrence of a problem of contact with the equipment on the hoistway 1 during a short repair period. It can be easily eliminated.
