Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0021] Such as Figure 1 to Figure 11 As shown, the cavity threading auxiliary device for train cable installation of the present invention includes a base 1 of a regular triangular prism structure, twelve fixing blocks 2, twelve fastening screws 3, six rollers 4, and six pin shafts 5 and three clamping bolts6. The twelve fixing blocks 2 are divided into six groups, and each group is symmetrically fixed on an outer wall of the base 1 .
[0022] The size of the base 1 is smaller than the size of the cavity. The base 1 is provided with a large screw hole 1-1 through the side wall at the center of each side wall. The base 1 is symmetrically provided with two holes outside each side wall. Groove 1-2, the shape of the groove 1-2 is the same as that of the fixed block 2 and the roller 4 after assembly, the depth of the groove is equal to the thick...

The invention relates to a cavity threading auxiliary device for mounting a train cable, which relates to the technical field of vehicle wiring and comprises a base, a plurality of fixing blocks, a plurality of fastening screws, a plurality of rollers, a plurality of pins and a plurality of clamping bolts. The roller is sleeved on the pin shaft, one pin shaft is connected with two fixing blocks, and is fixed in the groove of the outer side wall of the base by two fastening screws, and the upper part of the roller is protruded out of the groove. The invention changes the sliding friction between the cable and the mold cavity into rolling friction in the process of threading the mold cavity by installing a roller on the outer wall of the base, and at the same time, different sizes, differentquantities and different kinds of cables can be clamped by adjustable clamping bolts. The device of the invention reduces the number of personnel required for the mold cavity threading process, whichis accomplished by only one person at each end instead of the original four persons, thus greatly reducing the labor intensity. The surface of the cable is effectively protected, and the driving safety is enhanced. The inner surface of the mold cavity is effectively protected, and the aluminum profile structure is more safe and reliable.
Description
technical field [0001] The invention relates to the technical field of vehicle wiring, in particular to a cavity threading auxiliary device for installing train cables. Background technique [0002] The cavity threading in the high-speed EMU project is the most important and difficult process in the vehicle wiring process. In order to reduce the electromagnetic interference of cables, some important cables must pass through the cavity of the car body. Due to the small and long cavity of the car body, the number of cables that need to be threaded in each cavity is different, the cavity threading process often requires multiple workers to push and pull the cables at both ends of the threading, The cable slides in the cavity, the friction is high, and the whole threading process is time-consuming and laborious; the cable rubs against the inner wall of the cavity violently, which damages the cable skin and causes serious scratches on the surface of the aluminum cavity of the ca...
