  In the conventional railway vehicle motor maintenance device described in Patent Document 1 and Patent Document 2 described above, both have the advantage of enabling maintenance with the motor mounted on the vehicle, but overhauling the railway vehicle, No consideration is given to the maintenance and inspection of only the motor when performing a detailed maintenance and inspection. Therefore, depending on the railway vehicle, the MG that is a motor with a generator and the MM that is a main motor are selectively attached, and the size of the MM and the MG is almost twice as large. The same commutator cannot be used to maintain the commutator of the electric motor, and handling is low.

  The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to enable maintenance using the same maintenance device regardless of whether the motor is MM or MG. Another object of the present invention is to reduce the area occupied by the maintenance device.

  A feature of the present invention that achieves the above object is a maintenance device for a railway vehicle that maintains a driving machine used in a railway vehicle, and a conveyor line that conveys a rotor of a driving machine transferred from an automatic traveling vehicle that runs on a traveling line. And a grooving device capable of turning the commutator portion of the rotor that has passed through the conveyor line, the conveyor line being capable of transporting the rotor of the motor with the generator, and the first conveyor A first branching conveyor that can change the moving direction of the rotor of the adjacent main motor, a conveyor with a turntable adjacent to the first branching conveyor, and a second conveyor adjacent to the conveyor with the turntable And a third conveyor arranged parallel to the first line and capable of transferring the rotor of the main motor from the autonomous vehicle, and the third conveyor. A second line having a second branch conveyor adjacent to the bear and capable of transporting the rotor of the main motor to the first branch conveyor, and conveyed on both sides of the conveyor with the turntable and the second conveyor The pusher which makes the position of the rotor to be made variable is provided.

  And in this characteristic, it has the 1st rotor pallet which mounts the rotor of the motor with a generator, this 1st pallet is a pair of rotors whose position of the width direction is variable, and with respect to this rotor A pair of fixed rollers spaced apart in the axial direction, and may have height adjusting means for changing the height of the rotor whose position is variable, and a pair of rotors on which the main motor is mounted The second pallet may have a shorter axial length than the pallet on which the generator motor is mounted.

  The grooving device preferably has a cutting means for cutting the insulator held between the commutators of the rotor, and the pusher is a distance between the end face of the rotor and the end face of the first or second pallet. It is desirable to change the position in the direction perpendicular to the conveying direction of the first or second pallet so that is less than a predetermined distance.

  According to the present invention, since the grooving of MG and MM can be performed by the same grooving device, the occupation area of the maintenance device for the railway vehicle motor is reduced. Also, only one grooving device is required per line.

  Hereinafter, an embodiment of a maintenance line for a railway vehicle according to the present invention will be described with reference to the drawings. FIG. 1 is a top view of a maintenance line, and FIG. 2 is a diagram showing a flow of maintenance work. In the figure, the driving routes 15 to 17 for the AGV 40 are indicated by a one-dot chain line. In the present invention, the main motor (MM) 98 and the generator motor (MG) 99 can be maintained and inspected by the same grooving device 74 using the same maintenance line 100. Therefore, two types of motors with different sizes and weights travel on the travel route. Table 1 shows a comparison between the main motor (MM) and the generator motor (MG).

表１から明らかなように、発電機付モータ（ＭＧ）９９の軸長は、主モータ（ＭＭ）に比べて、２倍以上長い。したがって、発電機付モータ（ＭＧ）９９にあわせて保守ライン１００やＡＧＶ４０を設定すると、保守ライン１００が大型化し高価になる。また、主モータ９８の方が使用個数が多いにもかかわらず、頻度の少ない発電機付モータに合わせているので、装置が無駄である。

As is clear from Table 1, the shaft length of the generator-equipped motor (MG) 99 is twice or more longer than that of the main motor (MM). Therefore, if the maintenance line 100 and the AGV 40 are set in accordance with the motor with generator (MG) 99, the maintenance line 100 becomes large and expensive. Further, although the main motor 98 is used in a larger number, the apparatus is useless because it is matched with the generator motor with less frequency.

  For example, although a pallet having a size of about 800 mm square is used, a pallet having a size of 800 × 1600 mm is used, and handling properties are deteriorated. On the other hand, if the maintenance line 100 is set in accordance with the main motor 98, handling of the long generator motor 99 becomes difficult. An embodiment that meets this contradictory requirement is shown in FIG. An example of maintaining and inspecting the main motor 98 on the maintenance line 100 is shown below.

  The main motor 98 is removed from the bogie of the maintenance target railway vehicle that has traveled along the lead-in line 6 at the main motor removal portion where the tip of the travel route 15 is located (step 210). At this time, the main motor 98 is moved and attached to the transfer pallet 110 while keeping the posture taken out from the vehicle body using an overhead crane (not shown). The details are shown in FIG.

  In the posture when the removed main motor 98 is removed, the upper surface is the attachment surface to the vehicle body, and the attachment portion to the transfer pallet 110 is formed on the right side (the state of the broken line). The transfer pallet 110 is guided by a guide 11a formed on the tilting machine 11, and the guide 11b holds as a stopper. The tilting machine 11 has a rotating unit 12 that can rotate by 90 degrees. When the main motor 98 is attached to the transfer pallet 110, the rotating unit 12 that has been in the vertical state is changed to a horizontal state.

  A plurality of rollers 12a are arranged on the upper surface of the rotating unit 12. When the main motor 98 rotates 90 degrees, the transfer pallet 110 is slid on the roller 12a and the main motor 98 is sent to the AGV 40. An empty pallet storage 13 is secured near the tilting machine 11, and the transfer pallet 110 is supplied from the empty pallet storage 13 to the tilting machine when the main motor 98 is maintained and inspected.

  The main motor 98 mounted on the AGV 40 moves from the travel route 15 to the travel route 17 and is put into the maintenance line (step 2 14). The main motor 98 moved to the travel route 17 passes through the two corners and is sent to the air blowing device 68. Although not shown in FIG. 1, the following operations of the AGV 40 are all remotely controlled by commands from the control panel.

  FIG. 4 shows details of the air blowing device 68. In FIG. 4, the arrow indicates the moving direction of the main motor 98. The air blowing device 68 is a device for blowing dust adhering to the outer surface and gaps of the main motor 98 with compressed air, and an air blowing booth 68a for blowing dust is formed at the center. The air blowing booth 68a is a partitioned room, and a dust removal operation is performed by a human or a robot (step 216). The dust generated in the blower booth 68a is sucked from the suction port 66 by the blower 64, and only the dust is separated by the dust remover 63.

  In order to carry the motors to the air blowing device 68, three conveyor lines 30, 32, 34 perpendicular to the traveling route 17 are provided. The conveyor line 30 extends from one side of the circulation path formed by the travel route 17 to the other side, and a direction change conveyor 30e is interposed between the plurality of storage conveyors 30a to 30d and 30f. The conveyor line 30 is mainly used to send the main motor 98 to the air blowing booth 68a of the air blowing device 68. A storage conveyor 34a is disposed beside the direction changing conveyor 30e of the conveyor line 30 and is used to send the main motor 98 sent from the conveyor line 30 to the blowing booth 68a.

  The middle conveyor line 32 is used to send a motor with a generator, which will be described later, to the blowing booth 68a and to return from the blowing booth 68a. The conveyor line 32 includes a storage conveyor 32a, a direction changing conveyor 34b, and a manual turntable 32b disposed in the blowing booth 68a. An automatic door is provided between the blowing booth 68a and the direction changing conveyor 34b to prevent the dust in the blowing booth 68a from leaking to the outside.

  The conveyor line 34 is mainly used to send back the main motor 98 from the blowing booth 68a. The main motor 98 from which the deposits have been removed by the blower booth 68a is changed in the opposite direction by the manual turntable 32b, and is carried in the order of the direction changing conveyor 34b, the storage conveyor 34c, the direction changing conveyor 34d, and the storage conveyor 34e. It is transferred to the AGV 40 located on the route 17.

  Adjacent to the air blowing device 68, an exterior article removing device 42 is arranged. The details of the exterior article removing device 42 are shown in FIG. The exterior article removing device 42 is a conveyor 26 a with a manual turntable 26 b placed near the traveling route 17. The position of the main motor 98 is changed using the turntable 26b according to the work contents, and the external parts and the like that need to be replaced are removed (step 218).

  The main motor 98 from which the exterior product has been removed is sent to the disassembly / assembly support device 70. Details of the disassembly / assembly support device 70 are shown in FIG. In the disassembly / assembly support device 70, the frame, which is the stationary part of the main motor 98, and the rotor are separated (step 220). The main motor 98 is transferred from the AGV 40 to the direction changing conveyor 44 with the manual turntable 44b. Then, the frame and the rotor are separated by being sent to the disassembly / assembly support device 98. The separated rotor is placed on a pallet 46 sent to the direction changing conveyor 44 from an empty pallet storage place provided near the direction changing conveyor 44.

  The separated frame is returned to the air blowing device 68 using the AGV 40 while being placed on the pallet that has been placed on the pallet, and blown around the inside of the frame (step 230). The blown frame is sent to a frame maintenance place 50 having a conveyor 26a with a manual turntable 26b. The defective part or the like is maintained at the frame maintenance place 50 (step 232) and sent to the disassembly / assembly support device 70.

  On the other hand, the rotor cuts the commutator surface worn by contact with the brush after long-term use so that the contact with the brush becomes smooth. Therefore, the AGV 40 equipped with the rotor is sent to the grooving device 74 via the travel route 17. As shown in FIG. 7, the booth of the grooving device 74 has two lines, one for the main motor 98 and the other for the generator-equipped motor 99. In the main motor 98 line, the storage conveyor 58 and the branch conveyor 60 are arranged on a straight line.

  The generator motor 99 line is arranged parallel to the main motor 98 line, and the storage conveyor 36, the branch conveyor 38, the manual turn conveyor 62, and the storage conveyor 92 are arranged in a straight line up to the grooving device 74. . The rotor can be attached to the grooving device 74 past the manual turntable 62. Pushers 93 to 96 are disposed on both sides of the manual turntable 62 and the storage conveyor 92. In order to control the operation of the pushers 93 to 96, a control panel 97 is arranged beside these lines.

  The rotor that has been corrected and grooved by the grooving device 74 (step 244) is returned to 90 degrees by the manual turntable 62, and then returns to the branch conveyor 38 and the conveyor 36 and is mounted on the AGV 40. Then, each component necessary for the rotor is mounted at the rotor component mounting site 48 having the manual turntable 26b and the storage conveyor 26a (step 246). Further, each part of the rotor is maintained and adjusted (step 248). Since the repair of the rotor portion is completed, the rotor is sent to the disassembly / assembly support device 70.

  After the rotor and the frame are assembled together by the disassembly / assembly support device 70 (step 290), the main motor 98 is sent to the exterior product removal device 42 from which the exterior product has been removed for mounting the exterior product. The previously removed exterior product is attached to the main motor 98 (step 292), and the renewed main motor 98 is sent to the rotation test site 78. In the rotation test place 78, it is inspected whether insulation failure or predetermined performance is exhibited (step 294).

  The main motor 98 whose initial performance has been confirmed is temporarily stored in the automatic warehouse 90 and waits for completion of the maintenance of the cart unit and the vehicle body unit. When the maintenance of the cart part and the car body part is completed, the main motor 98 is taken out from the automatic warehouse and automatically travels on the travel line 16 mounted on the AGV 40 and provided with the tilting machine 20. And it can be changed to a pallet by the tilting machine 20, and the attitude | position can be changed from a horizontal direction to a perpendicular direction. As a result, it can be mounted on a carriage.

  The above is the procedure for maintenance and inspection of the main motor 98. Next, the case where the motor mounted on the railway vehicle is not the main motor 98 but the motor 99 with a generator will be described. In the case of the motor 99 with a generator, the axial length is about twice as long as that of the main motor 98, so that there are many restrictions on changing the direction of the motor. Therefore, in this embodiment, the number of direction changes is reduced.

  A detaching device 22 and a mounting device 24 for the generator-equipped motor 99 are provided adjacent to a part of the travel route 17. In the generator motor removing device 22, the motor 99 is removed from the carriage (step 210), and the motor 99 is mounted on the AGV 40 while maintaining the posture. The generator-equipped motor 99 is sent to the disassembly / assembly support device 54, and the rotor, which is a rotating portion, and the frame, which is a stationary portion, are disassembled (step 250). The frame is mounted on the AGV 40 and sent to the blowing booth 68a.

  When the AGV 40 carrying the frame that has traveled along the traveling line 17 arrives at the blowing line, the motor 99 is sent to the blowing booth 68a using the central line shown in FIG. When the air blowing is finished, the frame returns to the conveyor lines 32b, 34b, and 32a in the posture, is mounted on the AGV 40 again, and is sent to the frame maintenance device 56. In the frame maintenance device 56, the frame is maintained and inspected (step 254).

  After the rotor parts are removed from the rotor of the generator-equipped motor 99 by the rotor part attaching device 54 (step 260), the rotor is sent to the air blowing device 68. In the air blowing device 68, the rotor is sent to the air blowing booth 68a by using the middle line, and dust is removed to the inside of the rotor manually or by a robot (step 262). The blown rotor is sent to the position of the grooving device 74 mounted on the AGV 40 in order to correct and groove the commutator surface by the grooving machine 74 (step 264). At the grooving device 74, using a conveyor line extending straight to the grooving device 74, the manual rotary table 62 turns the rotor 90 degrees in a horizontal plane. Thereafter, the rotor is attached to the grooving device 74.

  The rotor whose commutator surface and the like are maintained by the grooving device 74 is integrated with the frame by the disassembly / assembly support device 54 dedicated to the motor 99 with a generator (step 280), and is rotated by attaching an exterior product such as a filter. It is sent to the test site 78. In the rotation test 78, whether or not insulation failure or initial performance is achieved is checked (step 284). If there is no abnormality, the motor 99 with a generator is temporarily stored in the automatic warehouse 90 (step 286). When the maintenance of the cart and the vehicle body is completed, the cart is taken out from the automatic warehouse 90, mounted on the AGV 40 traveling on the travel line 17, and attached to the cart with the motor mounting device 24 with a generator (step 300).

  In the above series of operations, the procedure related to the grooving device 74 will be described in more detail below by taking the motor 99 with a generator as an example. In FIG. 8, the disassembly / assembly apparatus 54 of the motor 99 with a generator is shown. In the disassembly / assembly apparatus 54, the conveyor 52 and the conveyor 54a with a manual rotation turntable are spaced apart and arranged in a straight line.

  A conveyor carriage 53 having a conveyor on the upper surface is placed between the conveyor 52 and the conveyor 54 with a manual rotation turntable. The conveyor carriage 53 is movable between the conveyor 52 and the conveyor 54a. An operation panel 55 is disposed in the vicinity of the disassembling and assembling apparatus 54 and is used when operating the conveyor carriage 53 and the conveyor 54a with a manual turntable. An overhead crane 57 is provided in the vicinity of the conveyor 54a in order to move the motor 99 with a generator placed on the conveyor 54a.

  Details of the work of disassembling the rotor and the frame using the overhead crane 57 are shown in FIG. The motor 99 with a generator carried by the AGV 40 (not shown) is transferred to the conveyor 52 together with the pallet 13. The conveyor cart 53 is brought close to the conveyor 52. On the other hand, a rotor pallet 13b, which will be described in detail later, is placed on the conveyor surface of the conveyor 54a with manual rotation turntable (see FIG. 9A).

  Next, a balance jig 99b fitted to the shaft 99a of the motor 99 with a generator is attached to the shaft 99a. The balance jig 99b has an L-shaped cross section, and a suspension ring to which the hook of the crane 57 is attached is formed in the middle part of the motor 99 in the axial direction. Lift the rotor through the hook on the suspension ring and let it float in the air. In this state, the pallet 13 is moved to the conveyor 52 together with the frame, and the rotor is taken out (see FIG. 9B).

  Fastening portions for bolts and nuts for holding the rotor portion on the frame are formed on the end surface on the shaft 99a side of the motor 99 and on the opposite surface. Therefore, in a state where the motor 99 is transferred to the conveyor carriage 53, the nut of the fastening portion is removed, and the rotor portion 99d is moved laterally (rightward in the drawing) using the crane 57. At this time, the frame 99c remaining on the conveyor cart 53 is returned to the conveyor 52 using the conveyors provided on the upper surfaces of the conveyor cart 53 and the conveyor 52 (see FIG. 4C). The rotor 99d is carried by the crane 57 to the conveyor 54a with a manual rotation turntable, and positioned on the rotor pallet 13d placed on the conveyor 54a.

  Thereafter, the frame 99c is transferred to the AGV 40 together with the pallet 13 and moved to, for example, the conveyor 56 at the retracted position. The rotor 99d placed on the conveyor 54a with manual rotation turntable is subjected to maintenance other than the grooving operation. At that time, when the turntable is raised, the turntable function works and the direction of the rotor 99d can be changed. When the maintenance of the rotor 99d is completed, the conveyor carriage 53 is brought close to the conveyor 54a and transferred to the conveyor carriage 53 together with the rotor pallet 13b. The conveyor carriage 53 is moved to the conveyor 52, and the rotor 99d is transferred from the conveyor 52 to the AGV 40.

  The rotor 99d mounted on the AGV 40 is conveyed to the line of the grooving device 74 shown in FIG. 7 and arrives at the position of the conveyor 62 with the turntable using the conveyor on this line. The subsequent operation will be described with reference to FIG. Since the rotor 99d has reached the conveyor 62, the operator raises the turntable of the conveyor 62 from the operation panel 97. When the turntable is raised, the turntable is free to rotate.

  When the rotor 99d arrives at the conveyor 62 (FIG. 10A), the drive means 93a, 93b, 95a, and 95b included in the pushers 93 and 95 cause the rotor 99d to move in the longitudinal direction (axial direction) in the line direction. It is aligned. Next, the direction of the rotor 99d is changed by 90 degrees so that the rotor 99d can be set in the grooving device 74 ((B) in the figure).

  That is, the pushers 93 and 95 are retracted by the driving means 93a, 93b, 95a, and 95b to approximately the longer longitudinal direction of the pallet 13 or the conveyor 62, and the turntable is rotated. A step pedal (not shown) is attached to the conveyor 62, and when the pedal is depressed, the turntable is free to rotate. Since the turntable is provided with fixing means that can be fixed every 45 degrees, the turntable is freely rotated and fixed when it is rotated 90 degrees. Next, the turntable is lowered using the operation panel 97, and the pushers 93 and 95 are spread at equal intervals (see FIG. 3C).

  In this conveyor 92 as well as the conveyor 62, the pushers 94, 96 arranged on both sides are retracted to the longer longitudinal direction of the pallet 13 or the conveyor 92 by the driving means 94a, 94b, 96a, 96b. In this state, the position adjustment with respect to the mounting position of the grooving device 74 is performed (see FIG. 4D). As shown in detail in FIG. 11, the conveyor 92 has a structure in which the height direction is variable. That is, there is a lifter 116 on the lower side, and a free roller 114 is disposed thereon.

  When the rotor 99d arrives at the conveyor 92, the lifter 116 is raised to make the free roller 114 operable. Since the operation of the free roller 114 is possible, the driving means 94a, 94b, 96a, 96b of the pushers 94, 96 are operated to move the pushers 94, 96 downward in FIG. As the pushers 94 and 96 move, the pallet 13b and the rotor 99d mounted thereon also move. The reason for moving the pushers 94 and 96 is as follows.

  When setting the rotor 99d to the grooving device 74, the setting is performed based on the pallet 13b. Therefore, the distance p from the end surface 122 on the shaft 99a side of the rotor 99d to the end surface 123 of the pallet 13b is 145 mm, and the deviation is 10 mm or less. Thus, the relative position of the rotor pallet 13b and the rotor 99d is set. This is shown in FIG. FIG. 4A shows the case of the rotor 99d of the motor 99 with a generator, and FIG. 4B shows the case of the main motor 98.

  The rotor pallet 13b has rotors 13e to 13h attached at two positions in the axial direction. FIG. 12C shows a top view of the rotor pallet 13b to which the rotors 13e to 13h are attached. The rotors 13e to 13h are formed in two rows in the width direction. Since the rotor 99d of the generator-equipped motor 99 is longer than the main motor 98, a pallet 13b having a size of 800 mm × 1300 mm is used.

  When the rotor 99d is placed on the pallet 13b, there is a high possibility that the rotor 99d is placed shifted in the vertical direction, the horizontal direction, or the like. Therefore, the rotors 13g and 13 on the opposite shaft side are movable in the width direction, and are fixed by changing the position according to the size using the mark 13j. Further, the rotors 13g and 13h can be moved in the height direction, and the vertical position is adjusted by a screw jack 13i provided near the rotors 13g and 13h. The screw jack 13i adjusts the inclination of the rotor 99d in the horizontal direction. When the entire pallet 13b is displaced in the vertical direction, the screw jack 13i is adjusted by a lifter provided in the grooving device 74.

  On the other hand, the axial length of the rotor 98d of the main motor 98 is shorter than that of the motor 99 with a generator. Therefore, only one rotor 13e, 13f is provided in the axial direction. Further, the axial length of the pallet 12b is shortened to 800 mm. The rotor 98d is set so that the deviation of the distance p between the shaft portion 98a end surface 122 and the pallet end surface 123 is 10 mm or less. When the relative positions of the pallets 12b and 13b and the rotors 98d and 99d are set to predetermined positions, the pallets 12b and 13b are moved to predetermined positions of the grooving device 74.

  When the relative positions of the pallets 12b and 13b and the grooving device 74 are determined as shown in FIG. 10D, the conveyor 91 on the grooving device 74 side shown in FIG. The rotors 98d and 99d are transferred to 91, and then the rotors 98d and 99d are held at the center of the grooving device 74. At this time, since the stopper is formed in the depth direction of the grooving device 74, the rotors 99d and 98d cannot move deeper than the stopper position. The stopper is formed by a screw, and the depth position can be finely adjusted by rotating the screw.

  In the rotors 98d and 99d held at both centers of the grooving device 74, the surfaces of the commutators 98e and 99e worn by the contact with the current collecting brushes 98f and 99f are turned by the same method as lathe machining. Thereafter, the insulator filled in the circumferential gap between the commutators is cut with a grooving tool that can move in the axial direction. Since the axially movable distance of the grooving tool is limited, the deviation of the distance p between the pallet end surface 123 and the rotor end surface 122 is set to 10 mm or less.

  Since the rotor pallets 12b and 13b and the grooving device line are configured in this way, the rotors of both the main motor and the motor with the generator, which are greatly different in axial length by the same grooving device, can be maintained. It became so. In addition, in the motor with a generator that has a long shaft amount and a large setting error, the position adjustment means is provided on the pallet, so it is possible to minimize the setting error when setting the rotor to the grooving device. .

  In the above embodiment, the main motor 98 and the generator-equipped motor 99 are mounted on the AGV 40 of the same shape, but the AGV 40 may be dedicated to each. In this case, the main motor 98 is 1 ton specification, and the generator motor 99 is 2 ton specification. Since the number of main motors is larger than that of motors with generators, the 2 ton specification AGV can also transport the main motor. Further, the transport range of the two AGVs is determined in advance and is usually arranged at a position where it does not interfere. However, when transporting the main motor using a large AGV, the small AGV is retracted to a position where it does not interfere.
