DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a vehicle
The present invention relates to a temporary bogie for transporting a vehicle body, which is used for performing inspection and repair of each part in a state where the bogie is separated from a vehicle.

[0002]

2. Description of the Related Art FIG.
This will be described with reference to FIG. 4, FIG. 15 and FIG. First, in FIG. 14, reference numeral 1 denotes a vehicle body, and a temporary bogie 2 is a temporary bogie of a type in which the vehicle body 1 is supported by a fixed support 3 and is separately installed on the ground side when performing inspection or repair of a lower portion of the vehicle body. The vehicle body 1 is listed up by the screw jack device 4 thus completed. The screw jack devices 4 are driven by the electric motor 5 and are provided at four places where the vehicle body 1 needs to be listed up in order to lift the vehicle body 1 at four places. Next, in FIGS. 15 and 16, the temporary bogie 6 has a hydraulic jack 8 provided on a support base 7, and the vehicle body 1 is listed up by the hydraulic jack 8.

[0003]

However, in the temporary bogie 2 of the type shown in FIG. 14, the ground equipment such as the screw jack device 4 is used as a means for raising the vehicle body 1. There is a disadvantage that the place where it can be raised is fixed. On the lower surface of the vehicle body 1, there are arranged many control devices or devices that require frequent inspection and maintenance. There are various types of inspections, and it is necessary to raise the vehicle 1 many times while sequentially transporting the vehicle to each shop in the inspection and repair shop. Must be installed as ground equipment. Under these circumstances, if it is possible to transport each shop of the inspection yard by fixing the vehicle body 1 in a constantly raised state, the above-described disadvantages can be solved. However, the ceiling height of the inspection yard, the crane equipment, and the vehicle body When there are restrictions on the height of a scaffold for upper work or an entrance / exit gate, it is impossible to transport the vehicle body 1 at the constantly raised height. Furthermore, recently, the demand for tall vehicles such as two-story vehicles has been increasing, and when transporting to an existing inspection site, the upper part interferes with the ground equipment, causing a huge amount of trouble. They are spending money on major renovations of the ground equipment and redesigning the layout.

Further, in the temporary bogie 6 of the type shown in FIGS. 15 and 16 described above, the hydraulic jack 8 on the temporary bogie 6
Therefore, the height of the vehicle body can be adjusted at an arbitrary position during the transportation. According to this method, the above-mentioned disadvantages of the method can be solved to some extent. However, unlike the above-described method, there is a disadvantage that the state in which the vehicle body 1 is raised is very unstable and danger exists. .
If a lateral load acts on the vehicle body for some reason while the vehicle body 1 is raised, a large moment load acts on the shaft portion of the hydraulic jack 8, and the hydraulic jack 8 falls or breaks, and the vehicle body 1 falls. . Usually, a gantry is installed to prevent this. However, the gantry has a considerable weight and requires a space for holding a large number of gantry. In addition, the work itself of raising the vehicle body 1 with the hydraulic jack 8 must be performed in a well-balanced manner in response to at least four places at the same time.
Operators are arranged at four locations, and the operation is performed while checking the imbalance of the four hydraulic jacks 8. For this reason, the workability is poor and a long time is required, which is a great hindrance to shortening the inspection and repair cycle time.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to move a vehicle body to an arbitrary position within a movable range, and to move the vehicle body to an arbitrary position within a movable range. It is possible to move up and down to the height, so that it can easily respond to the ceiling height of the inspection area, shorten the inspection and repair cycle time by minimizing the elevating operation of the car body, and move and raise the car body It is an object of the present invention to provide a temporary vehicle carrier for transporting a vehicle body that can maintain a safe and stable state of the vehicle body when the vehicle body moves up and down, and simplifies the operation of lifting and lowering the vehicle body to improve the working efficiency.

[0006]

And a restraining mechanism for restraining the frame in a forward / backward, left / right, and rolling direction on the underframe capable of traveling,
It is provided with an elevating mechanism for displacing the gantry in the vertical direction.

[0007]

[Function] Two temporary carriages are disposed, and the vehicle body from which the carriages are removed is supported by displacing the gantry of each temporary carriage upward or downward. And transport it to a place where maintenance work such as inspection is performed. The gantry is restrained from being displaced in the front-rear, left-right, and rolling directions by the restraining mechanism, so that a stable posture is maintained without unnecessary twisting or rotation in any of the supporting state and the running state. If it is necessary to displace the car body upward after moving to the desired place, the electric circuits and the like of each elevating mechanism of the two temporary carriages are connected by a cable so that they are linked to each other. Is displaced upward while synchronizing. The displacement position can be arbitrarily selected by the lifting mechanism. In the process of displacing upward, the gantry is restrained from unnecessary twisting and rotation by the restraining mechanism, and maintains a stable posture. After completing maintenance work,
Displace the gantry downward by the reverse operation of the above upward displacement,
The two temporary carriages are used to convey the trolley (the main trolley) to the vicinity of the place where the trolley (the main trolley) is located.
