DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting traverser facility for attaching and detaching a bogie of a railway vehicle,
The present invention relates to a device for supporting a vehicle after a bogie has been removed.

[0002]

2. Description of the Related Art JP-A-8-99797, which is a prior application filed by the present applicant, describes a facility for maintaining, inspecting, and repairing bogies and wheels of railway vehicles, underfloor equipment, and the like. A lifting traverser facility as shown in FIG. 14 is used. That is, the lifting traverser equipment is formed by digging a slot 40 having a width which allows the carriage B to be pulled out and lowered in the transfer path of the vehicle A so as to extend in a direction orthogonal to the transfer path in plan view. Inside, trolley B
A lift device 41 provided with a lifting table 42 on which is mounted is movably arranged along the longitudinal direction of the slot 40. Reference numeral 43 denotes a rail laid at the bottom of the slot 40.

[0003] Then, by transporting the vehicle A with the lift 42 of the lift device 41 raised, the carriage B is positioned at the place of the lift 42, and then the lift 42 is lowered to move the carriage B. Then, the lift device 41 is transferred to the position of the carriage transport path to raise the elevator 42, and then the carriage B
Is mounted on a transport rail and transported to the site of maintenance or the like. After the maintenance or the like, the truck B is mounted on the vehicle A and the vehicle A is transferred through the reverse process.

In this step, it is necessary to support the vehicle (body) A at a position near the bogie B from which the vehicle has been removed. Conventionally, a pair (or a plurality of pairs) of jacks 44 are placed on the left and right sides of the vehicle A on the floor, and the jacks 44 support the left and right edges of the vehicle A. .

[0005]

The vehicle body of the conventional vehicle A is provided with a steel base frame (car chassis) A1 extending substantially over the entire length thereof.
It had a structure with a floor panel and a torso attached to it. Therefore, when removing the bogie B from the conventional vehicle A, the base frame
A jack 44 was applied to A1.

On the other hand, in recent years, the vehicle A has a rigid structure by not having the base frame A1 but having a cylindrical structure as a whole, so that the vehicle A is reinforced only at a portion where the bogie B is mounted. There are many types called monocoques in which members are arranged. And while a large load acts intensively on the place where the jack 44 is applied, since the strength per unit area of each part is not large in the vehicle with the monocoque structure, the support part where the jack 44 can be applied Is limited to the location of the reinforcing member to which the truck B is attached.

Therefore, the conventional means for supporting the vehicle A by placing the jack 44 on the floor outside the slot 37 is difficult to remove the bogie B from the monocoque type vehicle A. (In order to support the monocoque type vehicle A by the method using the conventional jack 44, a long square member is applied to the lower surface of the vehicle A, and this is jacked.
It must be supported at 44, which is troublesome.)

SUMMARY OF THE INVENTION It is an object of the present invention to enable a truck to be easily and reliably attached and detached efficiently even in a monocoque type vehicle.

[0009]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a vehicle having a transport passage supported by a trolley, which is provided with a horizontal slot through which the trolley can be pulled out and lowered, in a direction crossing the transport passage in plan view. In the lifting traverser equipment in which a lift device for attaching and detaching the bogie is disposed so as to be freely movable along the longitudinal direction of the slot, the straddle spans the slot. A pair of frames for supporting the vehicle stopped in the state on both left and right sides thereof are arranged so as to extend across the slot.

In this case, the frame is preferably provided so as to be movable toward and away from the vehicle. Further, as a specific structure for supporting the vehicle with the frame, as described in claim 2, a support body in which the height of the receiving member that hits the lower surface of the vehicle is freely attached to the left and right frames is provided in the longitudinal direction of the frame. Or a small jack such as a screw-type jack may be mounted on a frame and the small jack may support the vehicle.

[0011]

According to the present invention, since the vehicle (vehicle body) is supported by the frame arranged so as to straddle the slot, the monocoque type in which the support portion of the vehicle is near the mounting position of the bogie. Even a vehicle can be easily and reliably supported. Therefore, the present invention
The support operation can be performed efficiently regardless of the difference in the structure of the vehicle, and the bogie can be efficiently extracted.

In particular, when the vehicle is transported, the frame may be retracted while the vehicle is being transported, so that it does not hinder the vehicle transport process or work under the floor. In addition, there are various types of vehicles having different sizes and structures, and the position of the support portion varies depending on the type of the vehicle. In claim 2, the position of the support portion is determined by the movement of the frame and the movement of the support. Easy to handle differences.
