specific Embodiment approach

[0028] Please refer to figure 1 , a motor vehicle cable protection device, which includes a sheath 4, a pad and a base 3, the pad is fixed on the base, the sheath 4 overlaps the pad, preferably, the pad is a split structure, and the pad includes a spacer A plurality of pads attached to the base 3 have gaps between adjacent pads. The specific implementation is as follows:

[0029] Please refer to figure 1 , the high-voltage EMU car end high-voltage cable protection device is composed of a sheath 4 and a car body part, and the sheath 4 is lapped on the upper part of the car body part.

[0030] Please refer to figure 2 , the sheath 4 includes a rubber part 41 and a third fixing element 43 . The rubber part 41 is covered on the outside of the cable, and the middle position of the rubber part 41 has a groove that matches the third fixing element 43. The third fixing element 43 is installed in the groove to lock the rubber part 41 to prevent the sheath 4 from Slip relative to ...

Abstract

The invention belongs to the technical field of railway traffic equipment, and discloses a protective device for a motor car cable. The protective device comprises a sheath, cushion blocks and a base, wherein the cushion blocks are fixed on the base; the sheath is in lap joint with the cushion blocks; preferably, the cushion blocks are of split type structures; the cushion blocks comprise a plurality of cushion blocks attached on the base at intervals, and a gap is formed between every two adjacent cushion blocks. According to the protective device, through the design of the independent rubber cushion blocks, external action time is effectively shared to each rubber cushion block unit, so that sustained stress for the rubber cushion blocks is avoided, the service life of each rubber block is prolonged, later maintenance is facilitated, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of rail transit equipment, and in particular relates to a cable protection device for motor vehicles. Background technique [0002] The high-voltage cable on the roof of the high-speed EMU is a particularly important power transmission cable required for its operation. It is mainly responsible for transmitting the high-voltage power of the pantograph to each high-speed power unit vehicle, but it is often attacked by severe weather. [0003] The protective base of the currently used high-voltage cable protection device is severely worn, and the wear-resistant rubber of the base is severely worn, torn or even peeled off. The main reason is that the rubber sheath and the rubber base continue to rub. Continuous wear and stress will cause the rubber base to tear or fall off, and the two ends of the damaged base are not severely worn, but they need to be replaced together, which is a waste.
