By turning off the current to the electromagnetic magnet 84, the bolt 72 is dropped into the collection box. It is supposed to be collected.

Next, a method for disassembling the trolley by the trolley disassembling apparatus 1 will be described.

First, the trolley 2 removed from the body of the railway vehicle.
Is placed at a predetermined position on the rail 19 of the frame 11 of the bogie disassembling apparatus 1 with a crane or the like (see FIGS. 3 and 4). Then, when the button of the automatic operation switch of the cart disassembling device 1 is pressed to start the automatic operation, the lifter 12 rises and the positioning roller 23 of the positioning rotating device 13 causes the wheel 4 to move.
Push up the flange 26 of the wheel 6 and the wheel 6 is several meters from the rail 19.
/ M rises (see FIG. 6), centering of the wheel set 6 with respect to the bogie disassembling apparatus 1 is completed, and the lifter 12 stops rising.

Next, the wheel inner surface positioning guide 43 of the flexible joint positioning device 38 is operated, and the guide 46 is brought into contact with the inner surface of the wheel 4 by the cylinder 47 as shown in FIG. Then, the flexible joint positioning guide 44 is set at a predetermined position. Next, the flexible joint position detecting device 3
When the sensor 41 of 7 operates and the rotation device 24 of the positioning rotation device 13 operates to rotate the positioning roller 23 and the wheels 4, the flexible joint 10 rotates via the speed reducer 9 that is interlocked with the wheels 4. The position of the reamer bolt 35 and the nut 36 of the nut 36 that connect the flexible joint 10 and the speed reducer 9 are detected by the sensor 41, and the rotating device 2
4 stops.

Then, the detection arm 42 of the flexible joint positioning guide 44 is raised by the operation of the cylinder, and the pins 49, 49 at the tip end hold the reduction gear side joint plate 33 of the flexible joint 10 to complete the positioning of the flexible joint 10. Yes (Fig. 11
reference).

Next, the removal arm 58 of the bolt-nut removal device 39 moves to the nut 36 side by the operation of the cylinder 54, and the socket 55 of the ratchet wheel 56 provided on the upper part of the removal arm 58 contacts the nut 6. At the same time, the two cylinders 52 of the ratchet drive device 57 are activated to operate the socket 55.
Rotates, and the nut 6 is inserted and fitted into the socket 55.
On the other hand, the rotation stopping portion 50 is fitted into the head of the reamer bolt 35 to prevent the reamer bolt 35 from rotating. And
The two cylinders 64 are operated and the tip of the push rod 62 is moved to the ratchet wheel 5.
When the ratchet wheel 56 is rotated by pushing the claw portion 65 of 6, the nut 36
Since it is fitted in the socket 55, it rotates with the rotation of the ratchet wheel 56, but does not move in the horizontal direction, and when the socket 55 rotates a specified number of times (for example, 100 times), the reamer bolt 35 is completely removed from the nut 36. The slack comes out of the joint plate 33 on the reducer side. When a gap is formed between the head portion of the reamer bolt 35 and the reduction gear side joint plate 33, the plate 51 is raised by the cylinder 52, and the screw portion of the reamer bolt 35 is clamped in the U-shaped portion 53. After that, the bolt-nut removing device 39 moves in the horizontal direction, and the reamer bolt 35 is pulled out from the nut 36 and the flexible joint 10. When the reamer bolt 35 is pulled out, the plate 51 descends and the reamer bolt 35 is put into the collection box. Further, the bolt and nut removing device 39 moves in the horizontal direction and the force of the spring 59 in the socket 55 causes the nut 36 to move.
Is ejected from the socket 55 and put into the collection box.

Next, the flexible joint positioning device 38 and the bolt-nut removing device 39 are lowered to the initial position, after which the reamer bolt 35 and nut 36 of the other reducer-side joint plate 33 are removed in the same manner as above. To be done.

The reamer bolt 35 and the nut 3 are also provided.
In parallel with the removal of 6, the bolts 72 attaching the main motor 8 to the bogie frame 3 are also removed.

That is, as the lifter 12 rises, the guide plate 73 ascends and comes into contact with the side surfaces of the mounting legs of the main motor 8 to attach the bolts 72 for mounting the main motor 8 to the bogie frame 3 to the bolt removing device 69. The positioning is performed after the cylinder 81 is rotated 90 °. Thereafter, the two ratchet sockets 78 of the bolt removing device 69 are moved to the bolt 72 side while being rotated by the cylinders 80, 80 and the swing arm 79, and the ratchet socket 78 is inserted and fitted into the bolt 72. Then, the socket with ratchet 78 rotates a prescribed number of times (for example, 140 times), the bolt 72 loosens, is removed from the main motor 8, and remains in the socket with ratchet 78. Then, the socket 78 with a ratchet pivots 90 ° by the rotary cylinder 81, and as the lifter 12 descends, the bolt removing device 6 is removed.
9 descends. After the descent, the cylinder 81 operates again and stops at a position facing the electromagnetic magnet 84 of the bolt recovery device 71. Then, the electromagnetic magnet 84 is moved to the cylinder 86.
As a result, it advances toward the bolt 72 in the socket 78 with a ratchet, and the electromagnetic magnet 84 attracts the bolt 72 and pulls it out of the socket 78 with a ratchet. After that, the electromagnetic magnet 84 to which the bolt 72 is attracted moves backward,
When it descends and comes over the collection box, the current is turned off and the bolt 72 is thrown into the collection box.

When the rietoma bolt 35, the nut 36 of the flexible joint 10 and the bolt 72 of the main electric motor 8 are put into the recovery box, the lifter 12 descends. Therefore, the positioning / rotating device 13, the flexible joint removing device 14 and the main electric motor removing device. 15 descends. Then, when the next wheel set 6 or the bogie 2 comes, these devices are lifted by the lifter 12 and the above operation is repeated.

All the above operations are automatically performed by pressing the button of the automatic operation switch of the trolley disassembling apparatus 1.

Note that the wheel shaft 6 and the main motor 8 are removed from the bogie frame 3 by another device (for example, a robot) after the above operation.

In this embodiment, the trolley disassembling apparatus 1 is provided with the frame 11, but it may be installed in the pit. Further, although the positioning / rotating device 13, the flexible joint removing device 14 and the main motor removing device 15 are mounted on one side of the frame 11, they may be mounted on both sides.
Further, each cylinder may be hydraulic, hydraulic, pneumatic, or a combination of rack and pinion and electric motor,
It is not limited to these.
