Problems solved by technology

Because there are many lines inside the cable, the whole is relatively thick, and it is difficult to fix the wiring, requiring the assistance of multiple workers, which is laborious. In addition, because the installation height of the cable is not fixed, it is necessary to add additional height-increasing equipment on the shelf when connecting, which is more cumbersome.

Embodiment 1

[0036] refer to Figure 1-4 , the present invention provides a differential network communication cable for a rail transit vehicle, comprising a support base 1, the top left side of the support base 1 is fixedly connected with a fixing platform 3, and the top right side of the support base 1 is fixedly connected with a second fixing platform at the front and rear ends. Block 17, fixed stage 3 and second fixed block 17 adjacent side front and rear ends are all fixedly connected with slide bar 10, and the outer periphery of slide bar 10 is slidably connected with mobile stage 11, and the top middle part of fixed stage 3 and mobile stage 11 is all fixed A second clip 15 is connected, and the top side of the second clip 15 is rotatably connected with the first clip 9, and the top side of the first clip 9 is fixedly connected with a connector 16, and the top rear of the fixed table 3 and the mobile table 11 Both are rotatably connected with a hydraulic cylinder 8, and the top of th...

Embodiment 2

[0039] refer to Figure 1-3 In this embodiment, on the basis of the structural scheme disclosed in the above-mentioned embodiments, threaded rods 6 are threadedly connected to the four corners of the top of the support base 1, and the bottom ends of the threaded rods 6 are rotatably connected to supporting feet 4, and the top ends of the threaded rods 6 All are provided with hexagonal prisms, the material of the supporting feet 4 is rubber and the shape of the supporting feet 4 is hemispherical. When in use, the supporting base 1 is placed under the cable main body 5, and the height of the supporting base 1 is adjusted by rotating the threaded rod 6.

Embodiment 3

[0041] refer to Figure 1-2 In this embodiment, on the basis of the structural scheme disclosed in the above-mentioned embodiments, several light poles 7 are equidistantly fixedly connected to the rear end of the top middle of the support base 1. The light poles 7 are goosenecks and the top ends of the light poles 7 are fixedly connected. There is a light bulb, turn on the light pole 7, and adjust the shape of the light pole 7 so that the top of the light pole 7 can be aligned with the position that needs to be wired, so that the wiring work can be completed more efficiently.

[0042] Working principle: when in use, place the support base 1 under the cable main body 5, and turn the threaded rod 6 to adjust the height of the support base 1. After adjusting to a suitable height, place the cable main body 5 on the second clip 15 and Inside the first clip 9, start the hydraulic cylinder 8 to clamp the cable main body 5, and then start the motor 12 to drive the screw 2 to rotate, a...

Abstract

A differential network communication cable for a rail transit vehicle disclosed by the present invention comprises a supporting base, the left side of the top end of the supporting base is fixedly connected with a fixing table, the front and rear ends of the right side of the top end of the supporting base are fixedly connected with second fixing blocks, and the front and rear ends of the sides, adjacent to the second fixing blocks, of the fixing table are fixedly connected with sliding rods. A movable table is slidably connected to the periphery of the sliding rod, second clamps are fixedly connected to the middles of the top ends of the fixed table and the movable table, first clamps are rotatably connected to one sides of the top ends of the second clamps, and connectors are fixedly connected to one sides of the top ends of the first clamps; the rear portions of the top ends of the fixed table and the movable table are rotationally connected with hydraulic cylinders. According to the invention, the cable main body is clamped through the first clamp and the second clamp, then the motor is started, the cable main bodies on the two sides are close to each other, the bulb on the lamp pole is turned on for illumination, and the overall height is adjusted by rotating the threaded rod, so that the efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a differential network communication cable for rail transit vehicles. Background technique [0002] The through-line cable is a cable for transmitting telephone, telegraph, fax files, TV and radio programs, data and other electrical signals. It is twisted by more than one pair of mutually insulated wires. , High transmission stability, good confidentiality, less affected by natural conditions and external interference, etc. Because there are many lines inside the cable, the overall is relatively thick, and it is difficult to fix the wiring, requiring the assistance of multiple workers, which is laborious. In addition, because the installation height of the cable is not fixed, it is necessary to add additional height-increasing equipment on the shelf when connecting, which is cumbersome. [0003] Therefore, it is necessary to develop a differential network communication cable for ...
