[0002] To control noise inside aluminum alloy subway cars, sound-absorbing material needs to be filled into the cavities of hollow aluminum profiles in the roof and side walls during manufacturing. Due to the limited length of the cavities, compressed air is generally used to blow the traction wire into the cavity, and after passing through, the sound-absorbing material is pulled into the cavity. To avoid the traction wire getting stuck when passing through the cavity, three standard air source ducts are currently used as the power source and connected to a straight connector for operation.
