Embodiment Construction

[0018] A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0019] The present invention is a self-towline type low-noise towline cable such as figure 1 As shown, it includes a cable body 1, the cable body 1 includes a sheath layer 2, and a cable core arranged in the sheath layer 2; Made of ground TPU material, it can effectively cover the cable core and protect the cable core. At the same time, it greatly enhances the wear resistance and resilience of the cable, and also plays a certain role in supporting the cable.

[0020] Such as figure 1 As shown, the cable core includes a first cable core 3, a second cable core 4 and a third cable core 5 arranged side by side, and the second cable core 4 and the third cable core 5 are located at the left and right sides of the first cable co...

Abstract

The invention discloses a self-trailing chain type low-noise trailing cable, comprising a cable core and a sheathing layer, wherein the cable core comprises a first cable core, a second cable core anda third cable core arranged side by side; The first cable core includes a first rigid nylon hollow tube and a first core wire arranged around the exterior of the first rigid nylon hollow tube. A second cable core comprises a second rigid nylon hollow tube and a second core wire, wherein the second core wires are arranged in an annular shape against each other, and the second rigid nylon hollow tube is located in a gap formed by the adjacent second core wires and / or an annular hole formed by the second core wires; The third cable core comprises a shielding layer, and twisted pairs of wires arranged in the shielding layer and a third rigid nylon air tube, wherein the twisted pairs of wires are arranged in a ring shape against each other, and the third rigid nylon air tube is positioned between adjacent twisted pairs of wires. The invention has simple structure, eliminates chain rails, and enables the cable to automatically drag the chain without the chain rails through the own structure, thereby reducing noise.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a self-towline low-noise towline cable. Background technique [0002] Most of the existing towline cables are installed in the towline chain rail, and the motor drives the chain rail to move as a whole. However, a big disadvantage of this installation method is that it is very noisy. The source of the noise is mainly the chain rail and the chain rail. It is caused by the impact of the bearing platform, and this installation method cannot be used in places with relatively high noise requirements. [0003] At present, the way to solve the noise of the drag chain is to carry out sound insulation treatment on the drag chain system, put the drag chain system into the soundproof box to run, and at the same time, change the drag chain carrying platform into a soft rubber pad, but this treatment has high installation costs, All-round sealing cannot be achieved, and the anti-noise effect ...
