Description

  The present invention relates to a work table apparatus for a vehicle that is detachably mounted on a vehicle connector.

  2. Description of the Related Art Conventionally, an operator performs inspection work or replacement work on a wiper device or a front glass of a railway vehicle in a state where the railway vehicle is stopped on an indwelling line of a vehicle base. For example, when inspection platforms such as a simple platform for crew members or a service deck for cleaning the inside of a vehicle are installed on both sides of a detention line at a vehicle base, the scaffolding plates cross the front of the railway vehicle and The worker is working over the bridge. However, when such an inspection table is not installed on both sides of the indwelling line, there is a problem that the scaffolding plates cannot be bridged on the inspection tables on both sides and the operator cannot work. In addition, when a pit with H-shaped steel welded rails laid on a concrete post is installed on the indwelling line for inspection or maintenance under the floor of a railway vehicle, the scaffolding plates are bridged between the left and right rails. An operator works by installing a pantograph type work table that can be moved up and down on the scaffolding plate. However, if there are no walls that support the scaffolding plate outside the left and right rails, the workable range is limited between the left and right rails, and workers must work outside the left and right rails. There is a problem that can not be. On the other hand, it is conceivable that a clamp mechanism for detachably clamping the rail abdominal portions of the left and right rails is installed on the work table so that workers can work even outside the left and right rails. However, when electric wires are laid on the rail abdomen of the left and right rails, there is a problem that the rail abdomen cannot be clamped by the clamp mechanism. For this reason, a work table apparatus for a vehicle for solving such a problem has been proposed.

  A conventional vehicle workbench device includes a base disposed between adjacent tracks on which a railway vehicle travels, a workbench whose one end is rotatably supported by the base, and a base. A platform that is formed at the end of the work platform opposite to the side to be mounted and on which the work platform rides when rotating, a cart that travels integrally with the work table, and along the length of the base A traveling rail for movably guiding the carriage is provided (for example, see Patent Document 1). In such a conventional vehicle work table device, the work table is rotated so as to cross this track while the front of the railcar body is stopped so that it is lined up on each track. A table is placed on the work table, and an operator cleans the front of the vehicle body. In this conventional vehicle work table apparatus, when the cleaning of the front surface of the railway vehicle body on one track is completed, the work table is rotated to the opposite side to clean the front surface of the rail vehicle body on the other track. After the cleaning operation is completed, the work table is rotated to a position where it can be stored in the base.

Below, as shown in FIG. 6, the case where the vehicle 5 provided with the coupler 12A is stopped and the vehicle 5 provided with the coupler 12B travels and is connected to the vehicle 5 provided with the coupler 12A is taken as an example. I will explain.
As shown in FIG. 6 (A), the release lever 16c by the biasing force of the spring 16d returns a connection state before (spring force) is being urged A ₁ direction, with respect to the center line of the coupling body 13 The flat surface of the key 16b is positioned at a rotation angle of approximately 45 °. As shown in FIG. 6B, when the coupler 12B approaches the coupler 12A, the guide part 13b on the coupler 12A side enters the guide insertion part 13c on the coupler 12B side, and the guide part on the coupler 12B side. 13b enters the guide insertion portion 13c on the coupler 12A side. When the guide portion 13b on the coupler 12A side contacts the key 16b on the coupler 12B side, the key 16b is forcibly rotated in the key chamber 16a by the guide portion 13b, and the key is locked with respect to the center line of the coupler body 13. The flat surface of 16b is located at a rotation angle of approximately 0 °. Similarly, when the guide part 13b on the coupler 12B side contacts the key 16b on the coupler 12A side, the key 16b is forcibly rotated in the key chamber 16a by the guide part 13b, and the center line of the coupler body 13 is reached. On the other hand, the flat surface of the key 16b is positioned at a rotation angle of approximately 0 °. As a result, the flat surface of the key 16b on the coupler 12A side and the flat surface of the key 16b on the coupler 12B side are gradually joined, and the release lever is integrated with the key 16b against the urging force of the return spring 16d. 16c the spring 16d is extended back to rotate in the a ₂ direction.

As shown in FIG. 6C, when the coupler 12B further approaches the coupler 12A, the coupling surface 13a on the coupler 12A side and the coupling surface 13a on the coupler 12B side are joined. At the same time, coupling the flat surface of the 12A side of the key 16b and the flat surface of the coupler 12B side of the key 16b is completely bonded, releasably been key 16b integrally by the biasing force of the return spring 16d lever 16c is A ₁ The return spring 16d shrinks by rotating in the direction. For this reason, the key 16b on the coupler 12B side is fitted into the key chamber 16a on the coupler 12A side, and the key 16b on the coupler 12A side is fitted into the key chamber 16a on the coupler 12B side. As a result, the coupling surface 13a on the coupler 12A side and the coupling surface 13a on the coupler 12B side are in close contact with each other, and the couplers 12A and 12B are in a coupled state.

When switching from the connected state shown in FIG. 6 (C) to the released state shown in FIG. 6 (A), one of the release levers 16c of the couplers 12A and 12B shown in FIG. 6 (C) is biased by the return spring 16d. It rotates in the a ₂ direction against the. As a result, in a state where the flat surface of the key 16b on the coupler 12A side and the flat surface of the key 16b on the coupler 12B side are completely joined, the flat surface of the key 16b is substantially the same as the center line of the coupler main body 13. The key 16b rotates until it is located at a rotation angle of 0 °. For this reason, the key 16b on the coupler 12A side comes out of the key chamber 16a on the coupler 12B side, and the key 16b on the coupler 12B side comes out of the key chamber 16a on the coupler 12A side, and the key chamber 16a and the key 16b. The fitting state is released, and the vehicles 5 can be separated from each other.
