TECHNICAL FIELD The present invention relates to bogie changing equipment for railway vehicles used for separating or connecting bogies to bogies when exchanging bogies or inspecting or repairing lower parts of the bogies while the trains are in a set state.

For example, Japanese Unexamined Patent Application Publication No. 2002-100001 discloses a bogie replacement facility for conventional railway vehicles. As shown in FIG. 11, the bogie exchange facility (bogie transfer facility) disclosed in Patent Document 1 includes a car body support device 101 for supporting a car body W1 of a vehicle (railway car) W on a main rail, and a straight line on the main rail. and positioned at an angle to the direction of the main rail at substantially floor level below the main rail on the side of the carriage support rail. A lifting device 104 for raising and lowering the side rail 103 and the truck supporting rail 102 between the main rail and the side rail, and rotating the truck supporting rail 102 between the main rail and the side rail. It substantially covers the first rotating device 105 resting on the device 104 and the pit 106 in which the first rotating device 105 and the lifting device 104 are installed. A bogie transfer facility 100 for vehicles comprising a second rotating device 107 rotated by rotation of a rotating device 105 .
According to the bogie transfer equipment 100, when the bogie W2 of the vehicle W that has traveled on the main rail and entered the vehicle is mounted on the bogie supporting rail 102, the traveling of the bogie W2 is stopped. 101, and then the elevator device 104 is operated to lower the truck support rail 102 to remove the truck W2 from the vehicle body W1. to match the side rail 103, and in this state, the truck W2 can be pulled out to the side rail 103.例文帳に追加

However, the second rotating device 107 of the bogie transfer facility 100 serves as a scaffolding during the work of separating or connecting the car body W1 and the bogie W2. It rotates with and substantially covers the pit 106 in which the first rotating device 105 and the lifting device 104 are installed and rests on the pit 106 . Therefore, the second rotating device 107 is always positioned at the same height as the lateral rail 103 . As a result, the height difference of the side rails 103 with respect to the main rail determines the height of the scaffolding during the work of separating or connecting the vehicle body W1 and the truck W2, and the height of the scaffolding is determined according to the height of the worker, the type of vehicle, etc. is difficult to adjust, and there is a problem that work efficiency and safety are lowered.

The present invention has been made to solve such problems, and adjusts the scaffolding height when separating or connecting the car body and the bogie when replacing the bogie or inspecting or repairing the lower part of the car body. To provide bogie replacement equipment for railway vehicles capable of improving work efficiency and safety.

In order to achieve the above object, the bogie exchange facility for railway vehicles according to the present invention has the following configuration.
(1) Car body support equipment for supporting the car body of the railway vehicle on the main rail, a bogie support rail formed so as to be arranged in a straight line with the main rail, and a first rail formed around the bogie support rail. a table, a side rail disposed on a floor surface lower than the main rail on the side of the truck support rail and facing in a direction intersecting the main rail, and the truck support rail stored in a pit. a rotating device that horizontally rotates the first table between the main rail and the side rail; 1 lifting device, and bogie replacement equipment for railway vehicles,
A second lifting device is provided in the pit for separating the first table from the truck support rail and lifting and lowering the first table between the main rail and the side rail.

In the present invention, since the first table is separated from the truck support rails in the pit and provided with the second lifting device for moving up and down between the main rail and the side rail, the first table and the truck support rails are provided. The first table can be independently raised and lowered so as to separate them in the vertical direction. Therefore, after the truck support rail and the first table are raised to the height of the main rail, the truck enters the truck support rail, and the truck support rail is stopped at that position. The table can be lowered to any height. As a result, the first table can be used as a scaffolding for separating or connecting the car body and the bogie when replacing the bogie or inspecting or repairing the lower part of the car body, and its height can be arbitrarily adjusted.

Further, according to the present embodiment, the first table 4 includes the first support portion 42 that supports the carriage support rail 3 from below, and the second table 9 supports the first table 4 from below. Since the second support portion 92 is provided, when the bogie W2 of the railway vehicle W enters the bogie support rail 3 from the main rail 1, the load applied to the bogie support rail 3 and the first table 4 is reduced to the second It can be received by the fall arrest device 9R via the table 9. Therefore, the load on the first lifting device 7 and the rotating device 6 can be reduced, and the first lifting device 7 and the rotating device 6 can be made compact.
As a result, while the first lifting device 7 and the rotating device 6 are made compact, the scaffolding for the work of separating or connecting the vehicle body W1 and the truck W2 can be widened, and work efficiency and safety can be further improved. . Note that the first support portion 42 and the second support portion 92 are preferably arranged below the rail.

Further, according to this embodiment, since the auxiliary table 5T rotating in the horizontal direction is provided on the extension of the siding rail 5, the vehicle body W1 of the railway vehicle W can be separated while being supported by the vehicle body support equipment 2. The carriage W2 can be moved to the auxiliary table 5T and can be easily unloaded. Further, the carriage W2 after repair can be placed on the auxiliary table 5T, moved to the carriage support rail 3, and connected to the vehicle body W1. As a result, it is possible to further improve the working efficiency at the time of replacing the carriage.

Although the bogie exchange facility 10 of the railway vehicle of the present embodiment has been described in detail above, the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention. For example, in the present embodiment, the second table 9 and the first table 4 are formed separately in the horizontal direction, but the second table 9 may be eliminated and only the first table 4 may be provided. In this case, the table support portion 81 of the second lifting device 8 is brought into sliding contact with the lower end of the first table 4 so that the first table 4 can rotate horizontally together with the rail 3 for supporting the carriage. In this embodiment, the auxiliary table 5T does not move up and down. The truck W2 can be transported to an inspection and repair site without using a crane.
