Abstract

The invention discloses a cable protection pipe sleeve for track traffic. The cable protection pipe sleeve comprises a sleeve body, wherein the sleeve body comprises a core layer; an outer layer is fixedly connected onto the outer surface of the core layer; an organic silica gel layer is fixedly connected onto the outer surface of the outer layer; an inner cavity of the core layer is fixedly connected with an anticorrosion layer; an inner cavity of the anticorrosion layer is fixedly connected with an electromagnetic shielding layer; an inner cavity of the electromagnetic shielding layer is fixedly connected with a waterproof layer; an inner cavity of the waterproof layer is fixedly connected with an anti-impact layer; an inner cavity of the anti-impact layer is fixedly connected with an alkali-free glass braided layer. Through the arrangement and the matched use of the sleeve body, the core layer, the outer layer, the organic silica gel layer, the anti-corrosion layer, the electromagnetic shielding layer, the waterproof layer, the anti-impact layer, the alkali-free glass braided layer and the fixing frame, the problem of short service life of the existing track traffic universal cable protection pipe sleeve is solved. The cable protection pipe sleeve for track traffic has the advantage of long service life and is worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a cable protection sleeve for rail transit. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of trains and railway technologies, There are more and more types of rail transit, which are not only used in long-distance land transportation, but also widely used in short- and medium-distance urban public transportation. During the construction of rail transit, it is necessary to take protective measures to protect cables. Extend the service life of the cable. The existing rail transit cable protection sleeve has a short service life. Problems with the protection sleeve may affect the use of the cable, bring unnecessary trouble to th...
