  In a conventional elevator, when replacing an existing control panel with a new control panel, for example, until the new control panel is in a state where all control of the equipment to be controlled by the new control panel can be performed, Some control may be performed by the existing control panel.

At this time, the new control panel provided alongside the existing control panel is provided at a temporary position in the machine room and connected to the relay box via a temporary cable. That is, the new control panel controls the control target devices that are communicably connected via the temporary cable, the relay box, and the second cable.
The temporary cable is removed, for example, at an appropriate time after the new control panel is in a state where it can perform full control of the equipment to be controlled by the elevator. Further, the existing control panel is removed together with the first cable, and after the new control panel is moved to the original installation position, the main cable is attached so as to connect between the new control panel and the relay box.
Thus, the replacement work from the existing control panel to the new control panel is completed.

  Here, a temporary cable can be used in order to replace an existing control panel of a different elevator with a new control panel. Since the distance between the temporary position of the new control panel and the relay box is different for each elevator, the temporary cable is used so that the distance between the temporary position of the new control panel and the relay box can be increased. It is necessary to use a material that has been prepared for a long time.

  In replacement work from the existing control panel to the new control panel, when the new control panel installed at the temporary position and the relay box are connected by a temporary cable, the surplus portion of the temporary cable is placed on the floor of the machine room. Will be. In this case, there is a problem that work space on the floor of the machine room is not sufficiently secured, and work efficiency when the existing control panel is replaced with a new control panel is lowered.

  Also, when replacing the existing control panel with the new control panel, the length of the temporary cable placed on the floor of the machine room is kept to a minimum and the work space is secured to ensure an appropriate length. When a temporary cable is prepared, it is necessary to prepare a temporary cable having a dedicated length for each elevator, which increases costs.

  The present invention has been made to solve the above-described problems, and it is possible to replace an elevator control panel using a temporary cable without reducing the work space on the floor of the machine room and using a different elevator control panel. An object is to obtain an elevator control panel replacement method that can use a common temporary cable even in the case of replacement.

  An elevator control panel replacement method according to the present invention includes an existing control panel provided in a machine room, a control target device provided outside the machine room, and a communication path between the existing control panel and the control target device. A method of replacing an elevator control panel for replacing an existing control panel of an elevator comprising a cable that is incorporated and connected at one end to the existing control panel, the step of temporarily installing a new control panel in the machine room, and the control A step of connecting the relay device provided for communication with the target device and the new control panel by a temporary cable so as to be able to communicate; a step of holding the temporary cable above the floor of the machine room; and an existing control panel A step of removing, a step of removing the temporary cable, and a step of arranging the new control panel at the main position and connecting the new control panel and the relay device with the main cable so as to communicate with each other.

  According to the elevator control panel replacement method according to the present invention, since there is a step of holding the temporary cable above the floor of the machine room, the temporary cable is placed on the floor surface of the machine room during work using the temporary cable. It is possible to avoid the placement and secure a working space on the floor of the machine room. Even if the temporary cable is long, the temporary cable can be disposed in the space above the floor of the machine room without any problem if a measure is taken such as circulating a part of the temporary cable. By making the temporary cable long in advance, for example, it is possible to cope with a case where the distance between the temporary position of the new control panel and the relay device becomes long. That is, since a common temporary cable can be used for exchanging existing control panels of different elevators, the cost for exchanging existing control panels for a plurality of elevators can be reduced.

The state which connected between the boards with the temporary cable is shown. FIG. 4 is a diagram for explaining an elevator control panel replacement method according to an embodiment of the present invention, and shows a state in which the new control panel is moved to the main position after the existing control panel is removed.

As shown in FIG. 3, the operator installs the new control panel 15 </ b> B at the temporary position in the machine room 3 while leaving the existing control panel 15 </ b> A as it is.
Next, the worker installs the relay device 19 described below, for example, at a position in the machine room 3 where the first cable 22 is suspended into the hoistway 2.

In addition, for example, the first cable 22 is cut in advance, and the portion of the cut first cable 22 is connected via the relay device 19. Of the separated first cables 22, the one arranged inside the hoistway 2 and connecting the relay device 19 and the car 10 is the hoistway cable 23, and the one arranged in the machine room 3 is the machine room. The cable 24 is used.
The relay device 19 has a function of connecting the temporary cable 25 and the cable in the hoistway so that communication is possible, and also connecting the machine room cable 24 and the cable in the hoistway so that communication is possible.

  The two cables obtained by cutting the first cable 22 have been described as being connected via the relay device 19. For example, the cable in the hoistway and the relay device 19 and the existing control panel 15A are connected to each other. Each machine room cable to be connected may be newly prepared and the first cable 22 may be removed, and then the new machine room cable and the hoistway cable may be connected via the relay device 19.

  Next, the worker connects the new control panel 15 </ b> B and the relay device 19 with the temporary cable 25. The temporary cable 25 has a plurality of signal lines, like the first cable 22.

  Further, the temporary cable 25 is held above the floor 3a of the machine room 3 by the holding means 30 described below.

  Here, the length of the temporary cable 25 is set to be long so that the existing control panel of different elevators can be replaced using the common temporary cable 25. That is, the length of the temporary cable 25 is set to be long so that it can cope with a case where the distance between the new control panel 15B and the relay device 19 becomes long.

The holding means 30 includes a cable support member 31 and a clip 34 as a fixing member that fixes the temporary cable 25 to the cable support member 31.
The cable support member 31 includes a pair of support columns 32 and a wire 33 that connects between the support columns 32.

  The worker erects one support column 32 at the position of the floor 3a of the machine room 3 corresponding to the relay device 19 with the length direction aligned with the height direction. In addition, the worker erects the other support column 32 at the position of the floor of the machine room 3 corresponding to the new control panel 15B, with the length direction aligned with the height direction.

  Next, the operator connects and fixes one end and the other end of the wire 33 to the upper end of the one support column 32 and the upper end of the other support column 32 so as to connect the upper ends of the pair of support columns 32. At this time, for example, the wire 33 is higher than the operator with respect to the floor 3a, and is stretched in parallel to the horizontal plane.

Next, the operator connects one end of the temporary cable 25 to an input / output terminal provided on the new control panel 15B, and connects the other end of the temporary cable 25 to an input / output terminal provided on the relay device 19. The relay device 19 and the new control panel 15B are connected by the temporary cable 25.
Needless to say, the temporary cable 25 is provided so as to constitute a part of the communication path between the new control panel 15B and the control target device.

Next, the operator holds the plurality of portions of the temporary cable 25 with the clips 34 so that the temporary cable 25 is held above the floor 3 a of the machine room 3 with respect to the support columns 32 and the wires 33. And fixedly connected to the wire 33.
The clip 34 is provided with respect to each of the support column 32 and the wire 33 so as to be spaced apart from each other in the longitudinal direction of the support column 32 and the wire 33.

For example, the surplus portion of the temporary cable 25 extends, for example, so as to go around a predetermined section in the vertical direction along the support pillar 32, and is then fixed to the support pillar 32 by the clip 34 above the floor 3 a. .
As described above, the temporary cable 25 is held above the floor 3 a of the machine room 3.
In this state, the new control panel 15B and the existing control panel 15A can perform system control of the elevator 1 jointly.
In addition, when a control target device such as a car operation panel is replaced with a new one, the existing one is replaced with a new one as appropriate.

  Next, when the worker has proceeded with the work until the elevator system can be controlled only with the new control panel 15B, the machine room cable 24 is disconnected from the relay device 19, and the existing control panel 15A and the machine room cable 24 are removed. To do.

  Next, the worker has a plurality of signal lines in the same manner as the first cable 22, and arranges a connection cable 27 as a main cable prepared in advance instead of the machine room cable 24.

The worker removes the temporary cable 25 and moves the new control panel 15B from the temporary position to the original position (main position) where the existing control panel 15A was installed.
Next, the worker connects the relay device 19 and the new control panel 15B with the connection cable 27. Needless to say, the connection cable 27 is provided so as to constitute a part of the communication path between the new control panel 15B and the control target device.
This completes the work of replacing the existing control panel 15A with the new control panel 15B.

  According to the elevator control panel replacement method of the present invention, the process of providing the new control panel 15B in the machine room 3, the process of connecting the new control panel 15B and the relay device 19 by the temporary cable 25, the machine room A step of holding the temporary cable 25 above the third floor 3a, a step of removing the existing control panel 15A, a step of removing the temporary cable 25, a new control panel 15B at the main position, and a new control panel. 15B and the relay device 19 are connected by a connection cable 27.

  Since there is a step of holding the temporary cable 25 above the floor 3a of the machine room 3, it is possible to avoid placing the temporary cable 25 on the floor 3a of the machine room 3 during work using the temporary cable 25. A work space on the floor 3a of the machine room 3 can be secured. Even if the temporary cable 25 is long, the temporary cable 25 can be disposed in the space above the floor 3a of the machine room 3 without any problem if a measure is taken such as circulating a part of the temporary cable 25. By making the temporary cable long in advance, for example, it is possible to cope with a case where the space between the temporary position of the new control panel 15B and the relay device 19 becomes long. That is, since the common temporary cable 25 can be used for exchanging the existing control panel 15A of different elevators, the cost for replacing the existing control panel 15A for a plurality of elevators can be reduced.

Further, when the temporary cable is placed on the floor 3a as in the prior art, the worker or the tool carried by the worker does not hit the temporary cable and damage the temporary cable, It is necessary to prepare a protective member for avoiding the operator from being caught by the convex portion.
In the present invention, since the temporary cable 25 is held above the floor 3a of the machine room 3, it is possible to omit the preparation of a protective member and to reduce the cost required to replace the existing control panel 15A with the new control panel 15B. .

  Further, as in the prior art, when a temporary cable is placed on the floor 3a of the machine room 3, in order to secure a work space, a dedicated temporary cable made to an appropriate length is provided for each elevator 1. It is necessary to prepare. In this case, when producing the temporary cable, considering the shape of the machine room 3 of each elevator 1, the appropriate length of the temporary cable is determined from the distance between the temporary position of the new control panel 15B and the installation position of the relay device 19. You have to do the work you want. In the present invention, this work is not necessary, and the cost is reduced from the viewpoint of the design of the temporary cable 25. Moreover, the replacement work of the existing control panel 15A of the elevator 1 can be started immediately by using the temporary cable 25 prepared in advance without having to wait for the delivery date of the temporary cable 25.

In the above embodiment, the holding means 30 has been described as being configured by the cable support member 31 and the clip 34 as a fixing member. However, the configuration of the holding means 30 is not limited to this, for example, cable support. The member 31 may be a bar-like member or a wire fixed so as to extend parallel to the horizontal plane above the floor 3 a using the wall of the machine room 3.
Further, although the fixing member has been described as the clip 34, for example, a string that binds and fixes the temporary cable 25 to the cable support member 31 or the wire 33 may be used.

  Further, although the main cable has been described as the connection cable 27 newly prepared at the time of replacement work from the existing control panel 15A to the new control panel 15B, the new cable is connected between the new control panel 15B and the relay device 19. However, if the machine room cable 24 can be used as it is, the machine room cable 24 may be used as a permanent cable without being removed. That is, it is not necessary to newly prepare the connection cable 27 as a permanent cable.

  The new control panel 15B has been described as moving from the temporary position to the permanent position where the existing control panel 15A was placed. For example, the new control panel 15B is not moved, and the temporary position is set as the permanent position. Alternatively, a position different from the position where the existing control panel 15A is provided may be set as the permanent position.

In addition, although it has been described that the relay device 19 is not provided in the elevator 1 before the repair, the existing control panel and the car are connected using the relay device 19 in the elevator 1 before the repair. Also good. That is, the existing control panel 15A and the relay device 19 may be connected by a first cable (machine room cable), and the relay device 19 and the car 10 may be connected by a cable in a hoistway. In this case, the first cable (machine room cable), the relay device 19, and the cable in the hoistway constitute a communication path between the existing control panel 15A and the car 10.
In this case, when the elevator 1 is repaired, the cable in the hoistway does not have to be replaced with a new one.
