Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a vehicle body structure reversing method and apparatus for improving the efficiency of outfitting work of a vehicle. It is characterized by adopting the air reversal method.

[Conventional technology]

In the manufacture of vehicles such as electric trains, first, a vehicle structure including a floor portion, both side portions and a roof portion is constructed, and various electric and mechanical parts are mounted on them.

The above-mentioned work is generally called outfitting work, and an extremely large number of various parts must be installed in the lower floor and the ceiling.

In that case, the worker has to work in an upward position, which is painful and inefficient.

Therefore, it has been proposed to perform the work by inverting or rolling over the vehicle structure. Conventionally, as such a device, the invention disclosed in JP-A-59-143759 is provided.

The above device is a plurality of fixing devices that are connected to both ends of the vehicle body,
It is composed of a plurality of supporting devices for rotating and supporting the vehicle body through the fixing device, and a fixing device for stopping the rotation of the vehicle body at a predetermined position.

In addition, a turning device for a trolley conveyor used for manufacturing automobiles and the like (Japanese Patent Publication No. 56-51965) is also provided.

[Problems to be solved by the invention]

Since the invention described in JP-A-59-143759 is provided on the ground, the ground space is occupied by these devices, the reversal location is specified, and vehicles of various sizes are further provided.

In that state, it is supported on a temporary stand, that is, on a temporary underframe or a temporary carriage.

〔Example〕

An example of an apparatus for carrying out the method of the present invention will be described with reference to the drawings.

In the figure, (A) is a vehicle structure including a floor portion (1), both side portions (2), a roof portion (3), and the like.

According to the present invention, a protective frame (B) is provided which surrounds the floor portion (1), both side portions (2) and roof portion (3) of the vehicle structure (A) and is provided with a chain guide (4) on the outer peripheral surface. It

More specifically, the protective frame (B) is composed of a lower frame (5) shown in FIGS. 2 to 4 and an upper frame (6) shown in FIGS. 5 to 7 in consideration of practical use. Has been done.

First, the lower frame (5) will be described. The lower frame (5) has a length such that the lower frame (5) can be fixed to the pillow elastic portion (7) under the floor of the vehicle structure (A) and protrudes to both sides of the vehicle structure (A). Composed.

In addition, the pillow tension portion (7) is a portion to which a truck is attached later, and is an important portion for bearing the load of the vehicle structure (A).
It is a part that is strongly structured.

The lower frame (5) is configured to have sufficient strength, and a guide pin (5a) adapted to a through hole (7a) provided in the pillow elastic portion (7) of the vehicle structure (A) in the center thereof. Are provided, spacers (9) having mounting holes (8) are provided on both sides thereof, and mounting holes (10) are further provided on both sides thereof.
Spacers (11) each having the above are provided, and the vehicle structure (A) can be fixed to the pillow elastic member (7) by using the mounting holes (8) and (10) with bolts, nuts or the like.

Further, the both ends of the vehicle structure (A) projecting from both sides are respectively connected with the upper frame (6) described later.

Each of the coupling portions is composed of a guide pin (12) that fits into a through hole (6a) provided on the upper frame (6) side and a mounting hole (13) provided around the guide pin (12).

The chain guide (4) is composed of pipe deformation ribs provided in parallel at appropriate intervals, and the reversing chain (15) is wound around the ribs.

Next, the upper frame (6) will be described. The upper frame (6) is formed in a substantially U shape surrounding both side portions (2) and the roof portion (3) of the vehicle structure (A), and both ends thereof are The connection part with the said lower frame (5) is each comprised.

Each of the coupling portions has a through hole (6a) that fits with the guide pin (12) provided on the lower frame (5) side and a mounting hole (16) that fits with the mounting hole (13) on the lower frame (5) side. It is composed of.

Therefore, if the connecting portions at both ends of the lower frame (5) and the upper frame (6) are overlapped and the mounting holes (13) and (16) are connected by bolts, nuts, etc. Structure (A)
The floor portion (1), the side portions (2), and the roof portion (3) are enclosed in a rectangular shape to form a protective frame (B).

Further, a chain guide (4) is provided on the outer peripheral surface of the upper frame (6) as in the lower frame (5). They are the lower frame (5)
Although it may be provided on the entire outer peripheral surface of the protective frame (B) including the upper frame (6), in the case of the illustrated embodiment, it is mainly provided at the corner portion.

Then, the reversing chain (15) is wound around the chain guides (4).

The reversing chain (15) preferably employs a roller chain in order to more reliably hold the protective frame (B) when the center of gravity of the vehicle structure (A) changes during reversing or when the suspension angle changes. .

Further, in the present invention, the inversion chain drive unit (1
8) is provided.

Although not shown in detail, the reversing chain drive unit (18) is provided with a drive sprocket for suspending the reversing chain (15) so as not to come off and for decelerating and rotating in the forward and reverse directions. Other safety devices are provided and can be lifted and lowered by being suspended and supported by an overhead traveling crane (19) or the like.

In the above-mentioned structure, the vehicle structure (A) is hoisted by a hoisting crane (not shown) of the vehicle structure (A), etc.
As shown in the second illustration, first, the lower frame (5) is fixed.

As already mentioned, they adapt the guide pin (5a) of the lower frame (5) to the through hole (7a) of the pillow elastic part (7), and use the mounting holes (8) and (10) for bolts, It is performed by nuts and the like.

Then, they are placed on a temporary stand (not shown), that is, on a temporary underframe or a temporary truck, and the upper frame (6) is lowered from above by using a crane or the like, and the lower frame (5).

As a result, the pillow elastic portions (7) on both ends of the vehicle structure (A)
A protective frame (B) is set in each of them.

After that, as shown in the first drawing, the reversing chain (15) is wound around the chain guide (4) part and the reversing chain driving part (18) formed on the outer peripheral surface of the protective frame (B), and the reversing chain (15) is circulated. The drive chain (15) is rotated by a reversible chain drive unit (18) which can be raised and lowered.

That is, the crane (19) uses the reverse chain drive (1
8) is lifted, the vehicle structure (A) is suspended and supported in the air by the reversing chain (15), and then the reversing chain drive unit (18) is driven, so that the vehicle structure (A) can be arbitrarily moved. It can be tilted at an angle, rolled over, inverted, etc.

Then, it may be supported and fixed on the prepared temporary stand, that is, on the temporary underframe or the temporary bogie.

Further, in the present invention, with the protective frame (B) attached, it can be moved to another factory in order to perform another work by coupling it with the temporary carriage in the state of overturning, reversing or the like.

The reversing chain drive section (18) provided at both ends of the vehicle structure (A) is synchronously controlled, and it is easy to perform wireless control as well as wired switch control.
