Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repair pit used for inspection / detachment of a bogie or underfloor equipment of a vehicle.

[0002]

2. Description of the Related Art In a vehicle repair pit, a work floor on which a bogie or underfloor equipment of a vehicle is placed and which is raised or lowered is moved to a lower portion of the vehicle to remove the bogie or underfloor equipment or the like. After the placement, the work floor is moved to the inspection / repair position for inspection / repair work. After the inspection / repair work is completed, the work floor is moved to the lower part of the vehicle and attached to the vehicle.

For this reason, a working floor is provided in the pit so as to be traversable between a mounting / removing position on a vehicle and an inspection / repair position, and a closing floor for closing an opening adjacent to the working floor is provided. When the work floor is in the installation / removal position on the vehicle, the inspection / repair position of the pit, which is the opening, is closed by the closing floor, and when the work floor crosses to the inspection / repair position, the closing floor is lifted by a crane or the like. It was removed and, if necessary, moved to an empty mounting / removal position.

[0004]

However, this closed floor is heavy because the load capacity in the work is taken into consideration.
It was a complicated task to move the work floor every time the work floor was moved.

Therefore, an object of the present invention is to provide a repair pit for a vehicle in which the movement of the closed floor is facilitated.

[0006]

In order to achieve the above-mentioned object, the present invention provides a work floor for mounting and removing a dolly or underfloor equipment of a vehicle in a pit and mounting / removing the work floor to / from the vehicle. And the inspection / repair position so as to be traversable, and the closing floor is provided so as to be traversable in the repair pit of the vehicle provided with the closing floor for closing the opening adjacent to the work floor.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on embodiments shown in the drawings.

The pit 1 is provided with a traveling carriage 3 having a working floor 2 which can be raised and lowered, and a closing floor 4 which closes an opening adjacent to the working floor 2. The traveling carriage 3 has a scissors provided on the upper surface thereof. The work floor 2 is moved up and down by opening and closing the link 5 with a cylinder (not shown), and the rail 6 laid on the bottom surface of the pit 1 can be traversed.

The closing floor 4 has on both sides rollers 8 for rolling guide rails 7 provided on both side walls of the pit 1 parallel to the rails 6, and by rotating the rollers 8 by driving a motor 9, The traveling carriage 3 is provided so as to be able to traverse in the transverse direction.

Further, on both side walls of the pit 1, there are formed grooves 11 with which a stopper 10 provided on the lower surface of the work floor 2 is engaged, and the stopper 10 is projected from the side surface of the work floor 2 to form the groove 11. The upper surface of the working floor 2 is closed by making it engage with the upper surface of the floor 4 and the floor surface outside the pit, and the weight of the vehicle 12 traveling on the working floor 2 for inspection / detachment is reduced. It is supported on the work floor 2.

As a result, the weight of the vehicle 12 is reduced by the traveling carriage 3
Since it is not necessary to support it, the load of the traveling carriage 3 can be reduced, and the load of the traveling carriage 3 can be made to correspond to the weight of the truck 13 having the first weight. Further, by engaging the stopper 10 with the groove 11, it is possible to prevent the work floor 2 from being lowered due to the leakage of fluid pressure in the cylinder that opens and closes the scissor link 5.

It should be noted that the work floor 2 may be prevented from lowering not only by the above means but also by other means.

The attachment / detachment work of the bogie 13 of the vehicle 12 by the pit 1 thus constructed will be described with reference to FIG. 4. As shown in FIG. 4A, the working floor 2 of the traveling bogie 3 is the vehicle. With the trolley 13 mounted and removed, the vehicle 12 is moved to position the trolley 13 on the work floor 2, the vehicle 12 is supported by a jack or the like outside the pit, and the trolley 13 is removed from the vehicle 12. On the work floor 2, pulling the stopper 10 inside the side surface of the work floor 2 to release the engagement with the groove 11, and open the scissor link 5 as shown in FIG. 4 (b). The work floor 2 is lowered, and FIG.
As shown in FIG. 3, the traveling carriage 3 is traversed to the inspection / repair position while the work floor 2 is lowered.

Interlocking with the traverse of the traveling carriage 3, the motor 9 of the closing floor 4 is driven to mount the work floor 2 before.
The floor 4 is traversed to the removal position to traverse the floor to close the opening, and as shown in FIG. 4D, the scissors link 5 is closed to raise the working floor 2 to the upper surface of the pit 1 and work the stopper 10. The carriage 13 is inspected and repaired by projecting from the side surface of the floor 2 and engaging with the groove 11. When the carriage 13 is attached to the vehicle 12, the order is reversed.

In this way, the interlocking floor 4 is traversed in the opposite direction in conjunction with the traverse of the traveling vehicle 3 to obstruct the opening, so that the interlocking floor 4
It is easy to move to the opening, and it is possible to prevent the danger by reducing the time when the opening is generated, and to shorten the working time.

Reference numeral 14 is a power supply cable for a transverse drive motor (not shown) of the traveling vehicle 3. Further, a small lift device may be provided on the upper surface of the work floor 2 for facilitating attachment and detachment of underfloor equipment such as a condenser.

[0017]

As described above, in the vehicle repair pit of the present invention, the work floor for mounting and removing the truck or underfloor equipment of the vehicle in the pit is used as the mounting / removing position for the vehicle. In addition to being able to traverse to the inspection / repair position, the closing floor that closes the opening adjacent to the work floor is provided so that it can easily move to the opening of the closing floor, and an opening occurs. The time can be reduced to prevent danger and work time can be shortened.
