Multi-core optical fiber composite carrier cable production device and production process

Abstract

The invention relates to a multi-core optical fiber composite carrier cable production device which comprises an optical fiber pay-off rack, a stainless steel plate pay-off rack, a coating mechanism, a primary stranding mechanism, a secondary stranding mechanism and a pay-off rack, wherein the coating mechanism, the primary stranding mechanism, the secondary stranding mechanism and the pay-off rack are sequentially arranged from front to back, and the coating mechanism comprises a base. An insulating coating assembly, a coating assembly and an online welding assembly are sequentially arranged on the base from front to back. Stainless steel coating and two-wire twisting are successively carried out on the multi-core optical fiber, so that the strength of the optical fiber is improved, the problem that the optical fiber is easy to break when the current optical fiber carrier cable is subjected to high-strength mechanical external force is solved, the damage of the surrounding environment to the optical fiber can be prevented, real-time monitoring, real-time evaluation and real-time alarm of the carrier cable are realized, the operation and maintenance quality of a contact network system can be greatly improved, and even if an individual optical fiber is broken, the signal transmission of the whole multi-core optical fiber is not influenced.

Description

Technical field [0001] The present invention relates to electric railway catenary and rail transportation technology, particularly to a multi-core optical fiber composite catenary production equipment and production processes. Background technique [0002] Along the railway catenary erected over a particular type of transmission line, which usually consists of several parts catenary, the contact wire, cantilever means, positioning means, and the base struts and the like, wherein the main catenary suspension play contacting the line of action. Current of high-speed railway catenary essentially copper alloy stranded wire, primarily as a load acting in the suspension are subjected to contact, along with the carrier function. Catenary working condition is extremely important in high winds, ice and other special conditions may cause catenary off the bow, break failure, causing train accidents, require frequent maintenance and overhaul. At present, the Chinese high-speed rail catenary ...

AI Technical Summary

Problems solved by technology

The working state of catenary cables is extremely important. Under special working conditions such as strong winds and icing, it may cause failures such as catenary detachment and wire breakage, resulting in safety accidents in train operation. Therefore, frequent maintenance and repairs are required

At present, the daily operation and maintenance of China's high-speed railway catenary system requires a large number of catenary workers with sufficient professional skills and experience. The continuous recording and monitoring of the operating status and technical parameters of the catenary cannot detect and eliminate problems in the operating status of the catenary in real time, and cannot predict and determine possible faults in the catenary in advance, requiring many experienced staff in daily maintenance. It is easy to make misjudgments when judging in the process

When a fault occurs in the catenary, many people are required to search for the fault location separately along the line, which consumes a lot of manpower and material resources, and the efficiency is extremely low

[0003] At present, there are also catenary cables embedded with optical fibers. The tiny optical fibers are covered by cable sheath, aramid yarn, and buffer layer, and finally encapsulated in a plastic sheath. When the mechanical force is strong, the optical fiber is easy to break, the signal is lost, or the entire optical fiber channel is disconnected, and the signal cannot be transmitted. The production process is unreasonable, the production cost is increased, and the yield is low.
