Description

Technical Field

[0001] The invention belongs to the field of rail transit vehicle new manufacturing and maintenance equipment installation, and in particular, relates to a vehicle wire duct preassembly positioning device and a vehicle wire duct installation method. Background Art

[0002] During the installation of the central cable duct of existing high-speed rail vehicles, the manufacturing errors of the car body cross beam slide, car body mounting seat, and equipment mounting ears lead to uncertainty in the accurate connection dimensions between the cable ducts. During installation, the cable duct needs to be positioned according to the actual conditions of the car body cross beam slide and car body mounting seat, and pre-positioning must be performed on the car body before wiring the cable duct.

[0003] The installation steps of the central cable duct of the existing high-speed rail vehicle include the following steps:

[0004] (1) Wire duct transportation and pre-installation: Place the wire duct on a special storage and transportation tooling trolley and transport it to the installation position under the vehicle. Align the lifting ears of the wire duct with the embedded bolts of the vehicle body cross beam slide and the eyelets of the vehicle body mounting seat. Use nuts to pre-tighten the wire duct. Then pre-tighten the entire vehicle wire duct from the first end to the second end.

[0005] (2) Wire trough adjustment and marking: After all wire troughs on one side are pre-tightened, the connection position of the wire trough may not be aligned due to the error of the body beam slide groove. In this case, the X-direction positioning of each wire trough needs to be adjusted through the oblong mounting holes on the wire trough ears to ensure that the connection between each wire trough can be penetrated by bolts for installation. After the adjustment is completed, mark the relative position of the wire trough connection.

[0006] (3) Disassembly of the cable trough: Remove the bolts at the connection between the cable troughs, remove the installation bolts at the cable trough ears, move the cable trough to the storage and transportation tooling, and transport it to the cable trough pre-assembly position, and place it in sequence from the first end to the second end according to the installation sequence of the existing vehicle.

[0007] (4) Wire duct connection and wiring: At the wire duct pre-assembly station, determine the relative positions of the wire ducts according to the marking records, and use bolts and nuts to pre-assemble the vehicle wire ducts together, and then carry out wiring after the connection is completed.

[0008] Therefore, when installing the cable duct of the current high-speed rail vehicle, the cable duct needs to be pre-assembled and positioned on the vehicle body, and the cable duct is transported multiple times between the installation station and the pre-wiring station, resulting in low installation efficiency of the cable duct.
