Fig. 9 is a front view of the cable body 5a of the control panel 4 shown in fig. 3. Fig. 10 is a right side view of the cable body 5a of the control panel 4 shown in fig. 3. The cable body 5a includes a metal pipe 10 as a cover member bent in a U shape and a connection cable 11 housed inside the metal pipe 10.
Each cable connector 14 is configured to be attachable to and detachable from the upper frame connector 16, the lower frame connector 17, the three upper side connectors 12a, 12b, and 12c, and the three lower side connectors 13a, 13b, and 13c of the frame 8 by one operation.
Thus, the upper frame connector 16 serves as both an attachment portion for mechanically attaching the respective cable bodies 5a, 5b, 5c, and 5d to the frame 8 and a connection portion for electrically connecting the connection cable 11 to the existing cable 6. The lower frame connector 17 serves as a mounting portion for mechanically mounting the cable bodies 5a, 5b, 5c, and 5d to the frame 8 and a connecting portion for electrically connecting the connection cable 11 to the motor cable 7. Further, the upper- side connectors 12a, 12b, and 12c and the lower- side connectors 13a, 13b, and 13c serve as attachment portions for mechanically attaching the cable bodies 5a, 5b, 5c, and 5d to the control units 9a, 9b, and 9c and connection portions for electrically connecting the connection cables 11 to the control units 9a, 9b, and 9 c.
Next, a maintenance and inspection method of the control panel 4 will be described with reference to fig. 3 and 11. When performing maintenance work on the control panel 4, a control unit requiring maintenance among the control units 9a, 9b, and 9c is detached from the frame 8.
Fig. 11 is a diagram showing a state where the control units 9a, 9b, and 9c are detached from the control panel 4 shown in fig. 3. In the following description, the mounting state of each of the cable bodies 5a, 5b, 5c, and 5d shown in fig. 3 is referred to as the 1 st mounting state. The respective mounting states of the cable bodies 5a, 5b, and 5c shown in fig. 11 are set as the 2 nd mounting state. That is, the mounting state of the cable bodies 5a, 5b, and 5c with respect to the control units 9a, 9b, and 9c can be selected between the 1 st mounting state shown in fig. 3 and the 2 nd mounting state shown in fig. 11.
First, a state before the control units 9a, 9b, and 9c are detached from the control panel 4 will be described with reference to fig. 3.
In the 1 st mounted state shown in fig. 3, the control units 9a, 9b, and 9c are electrically connected to the connection target devices via the connection cables 11 of the cable bodies 5a, 5b, 5c, and 5d, respectively. The connection target devices corresponding to the control units 9a, 9b, and 9c are the existing cables 6, the motor cables 7, or other adjacent control units. That is, the connection target devices corresponding to the control unit 9a are the existing cable 6 and the adjacent other control unit 9 b. The connection target device corresponding to the control unit 9b is the other two adjacent control units 9a and 9 c. Further, the connection target devices corresponding to the control unit 9c are the other control unit 9b and the motor cable 7 adjacent thereto.
Next, in the separation step, the cable bodies 5a, 5b, 5c, and 5d are separated from the existing cable 6, the motor cable 7, and the three control units 9a, 9b, and 9 c. That is, the 1 st end 51a and the 2 nd end 52a of the cable body 5a are separated from the upper frame connector 16 of the frame 8 and the upper side connector 12a of the control unit 9 a. Further, the 1 st end 51b and the 2 nd end 52b of the cable body 5b are separated from the lower side connector 13a of the control unit 9a and the upper side connector 12b of the control unit 9 b. Further, the 1 st end 51c and the 2 nd end 52c of the cable body 5c are separated from the lower side connector 13b of the control unit 9b and the upper side connector 12c of the control unit 9 c. Further, the 1 st end 51d and the 2 nd end 52d of the cable body 5d are separated from the lower side connector 13c of the control unit 9c and the lower side frame connector 17 of the frame 8.
Next, in the mounting step, as shown in the 2 nd mounting state of fig. 11, the respective cable bodies 5a, 5b, and 5c are mounted on the control units 9a, 9b, and 9c while being shifted in position from the 1 st mounting state. That is, the 1 st end 51a of the cable body 5a is attached to the upper side connector 12a of the control unit 9a, and the 2 nd end 52a is attached to the lower side connector 13 a. The 1 st end 51b of the cable body 5b is attached to the upper connector 12b of the control unit 9b, and the 2 nd end 52b is attached to the lower connector 13 b. The 1 st end 51c of the cable body 5c is attached to the upper side connector 12c of the control unit 9c, and the 2 nd end 52c is attached to the lower side connector 13 c. Thus, the cable bodies 5a, 5b, and 5c can be used as gripping portions for individually pulling out the control units 9a, 9b, and 9c from the frame 8. At this time, the respective cable bodies 5a, 5b, and 5c are separated from the connection target devices.
In addition, during the maintenance and inspection work of the control units 9a, 9b, and 9c, the cable body 5d is temporarily placed in an appropriate storage place in a state of being separated from the control panel main body 9 and the frame 8.
As shown in fig. 11, in the drawing step of the control units 9a, 9b, and 9c, the cable bodies 5a, 5b, and 5c attached to the control units 9a, 9b, and 9c, respectively, function as gripping portions. The operator pulls out the control units 9a, 9b, and 9c, which are part of the control panel main body 9, from the recesses 8a, 8b, and 8c of the frame 8 in which the control panel main body 9 is housed, by using the respective cable bodies 5a, 5b, and 5c, which are the gripping portions. After that, maintenance work is performed on the pulled out control units 9a, 9b, and 9 c. All of the control units 9a, 9b, and 9c may be pulled out from the frame 8, or one or both of the control units may be pulled out from the frame 8. In addition, in the 2 nd mounting state shown in fig. 11, the cable bodies 5a, 5b, 5c, and 5d that are temporarily separated from the frame 8 and the control units 9a, 9b, and 9c can be mounted to any of the control units 9a, 9b, and 9 c.
After that, when the maintenance work for the control unit requiring maintenance is completed, the control units 9a, 9b, and 9c are stored in the frame 8 in the reverse order to the above. Thereafter, the installation state of each of the cable bodies 5a, 5b, 5c, and 5d to the control panel main body 9 is set to the 1 st installation state, and the maintenance work of the control panel 4 is completed.
As described above, each of the cable bodies 5a, 5b, 5c, and 5d as the gripping portion provided in the control panel 4 of the present embodiment includes the connection cable 11 for electrically connecting the control units 9a, 9b, and 9c to the devices to be connected, respectively. In addition, the mounting state of the cable bodies 5a, 5b, and 5c to the control units 9a, 9b, and 9c can be selected between a 1 st mounting state in which the control units 9a, 9b, and 9c are electrically connected to the connection target device via the connection cable 11 and a 2 nd mounting state in which the cable bodies 5a, 5b, and 5c are separated from the connection target device. Therefore, the cable bodies 5a, 5b, and 5c integrated with the connection cable 11 can be used as the gripping portions simply by changing the positions of the cable bodies 5a, 5b, and 5c with respect to the control units 9a, 9b, and 9 c. As a result, the control units 9a, 9b, and 9c can be detached from the frame 8 during maintenance work by grasping the respective cable bodies 5a, 5b, and 5 c. That is, when the control units 9a, 9b, and 9c are detached from the control panel 4, the connection cable provided separately from the grip portion does not become an obstacle. Further, the operator does not have to pull around the connection cable and concentrate the connection cable to a place where the operator does not interfere with the work. Therefore, the burden of maintenance work on the control panel 4 can be reduced.
Further, in the case where the control units 9a, 9b, and 9c pulled out from the frame 8 are connected to the connection cables provided separately from the grip portions, the moving range is limited by the length of the connection cables. Therefore, places where the control units 9a, 9b, and 9c can be placed are limited. In contrast, in the control panel 4 and the maintenance and inspection method for the control panel 4 according to the present embodiment, since the cable bodies 5a, 5b, and 5c having the connection cable 11 can be used as the gripping portions, the maintenance and inspection work can be performed on the control units 9a, 9b, and 9c at any place.
The control panel main body 9 has a plurality of control units 9a, 9b, and 9 c. That is, another control unit different from the specific control unit is set as the connection target device, and the specific control unit is electrically connected to the other control unit via the connection cable 11 in the 1 st mounting state. Therefore, only the control units that require maintenance work can be taken out of the control units 9a, 9b, and 9c that are part of the control panel main body 9. Further, since each control unit 9a, 9b, or 9c can be detached from the control panel 4, the burden on the operator is reduced as compared with a case where the control panel main body 9 as a single component is taken out.
Each of the cable bodies 5a, 5b, 5c, and 5d has a metal pipe 10 as a cover member for housing a connection cable 11. Thus, when the cable bodies 5a, 5b, 5c, and 5d are used as the holding portions, the connection cable 11 is protected by the metal pipe 10, and disconnection is prevented. Further, the operator can grip the cable bodies 5a, 5b, 5c, and 5d more easily, and the workability is further improved.
In the 2 nd mounting state shown in fig. 11, the 1 st end portions 51a, 51b, and 51c of the cable bodies 5a, 5b, and 5c are mounted on the 1 st mounting portions of the control units 9a, 9b, and 9c, i.e., the upper side connectors 12a, 12b, and 12 c. In the 1 st mounted state shown in fig. 3, the upper connectors 12a, 12b, and 12c also serve as connection portions for electrically connecting the connection cables 11 of the cable bodies 5a, 5b, and 5c to the control units 9a, 9b, and 9 c. This enables the upper connectors 12a, 12b, and 12c to be used as attachment portions for the grip portions and connection portions for connecting the cables 11, and the structures of the control units 9a, 9b, and 9c to be simplified.
Further, in the 2 nd mounting state shown in fig. 11, the 2 nd end portions 52a, 52b, and 52c of the cable bodies 5a, 5b, and 5c are mounted on the 2 nd mounting portions of the control units 9a, 9b, and 9c, i.e., the lower- side connectors 13a, 13b, and 13 c. In the 1 st mounted state shown in fig. 3, the lower connectors 13a, 13b, and 13c also serve as connection portions for electrically connecting the control units 9a, 9b, and 9c to the devices to be connected, respectively. Accordingly, the lower connectors 13a, 13b, and 13c can be used as the mounting portions and the connecting portions, as in the upper connectors 12a, 12b, and 12c, and the configurations of the control units 9a, 9b, and 9c can be simplified.
In the maintenance and inspection method of the control panel 4 according to the present embodiment, the cable bodies 5a, 5b, 5c, and 5d are separated from the control units 9a, 9b, and 9c of the control panel main body 9 and the connection target devices in the separation step, respectively, but the method is not limited thereto. For example, after the 1 st end 51a of the cable body 5a is separated from the connection target device, the cable body 5a may be rotated around the 2 nd end 52a attached to the upper connector 12 a. Thus, the 1 st end 51a of the cable body 5a is attached to the lower side connector 13a of the control unit 9a, and the cable body 5a can be used as a grip. The cable bodies 5b and 5c can be used as the gripping portions by rotating and moving in the same manner. At this time, the 1 st end 51d of the cable body 5d not used as the grip is also separated from the lower side connector 13c of the control unit 9 c.
In the present embodiment, the number of control units constituting the control panel main body 9 is not limited to three.
The cover member is not limited to a metal pipe, and may be a plastic pipe.
Further, not limited to this embodiment, the 1 st mounting portions of the control units 9a, 9b, and 9c may be the lower side connectors 13a, 13b, and 13c, and the 2 nd mounting portions may be the upper side connectors 12a, 12b, and 12 c.
