Wire releasing device with replaceable outer sleeve

Abstract

The invention provides a wire releasing device with a replaceable outer sleeve. The replaceable outer sleeve is sheathed on a winding drum and the outer sleeve is provided with an outer bulge; a shock absorber is arranged inside of the outer bulge connected with a pulling rope to carry out combined shock absorption. The wire laying device takes full account of vibration state of the optical fiber and can be well applied to the occasions where the wiring requirements are high. The wire laying device has the advantages of artful structure and low cost.

Description

technical field [0001] The invention relates to a reel pay-off device, in particular to an optical fiber pay-off device with a replaceable jacket. Background technique [0002] In the process of fiber optic cable cutting, due to the large number of fiber cables, it is usually necessary to cooperate with a pay-off device to cut the fiber cables. At present, in the optical fiber, cable and other industries, passive pay-off devices are being widely used, but most of them have simple structures, insufficient protection, and harsh use environments. Jitter occurs when changing from a coiled state to a straightened state, affecting the wiring environment. [0003] In order to solve the problem of optical fiber distribution, in a mechanical damping passive pay-off device disclosed in Patent Document 1, a passive pay-off reel 10 for cable pay-off is provided, but it does not take into account that sometimes the optical fiber will Work in a harsh environment, but can not protect the...

Problems solved by technology

At present, in the optical fiber, cable and other industries, passive pay-off devices are being widely used, but most of them have simple structures, insufficient protection, and harsh use environments. Jitter occurs when changing from winding state to straight state, which affects the wiring environment

[0003] In order to solve the problem of optical fiber distribution, in a mechanical damping passive pay-off device disclosed in Patent Document 1, a passive pay-off reel 10 for cable pay-off is provided, but it does not take into account that sometimes the optical fiber will Work in harsh environment, but can't protect the fiber well

[0004] Correspondingly, in order to protect the optical fiber, in the optical fiber winding device disclosed in Patent Document 2, a housing 10 providing optical fiber protection is provided outside the movable winding core 20, but the housing is not universal and cannot be replaced. The problem of affecting the wiring environment due to the jitter generated when the optical fiber is changed from the coiled state to the straightened state is not considered when the optical fiber is arranged in a long-distance, high-altitude, etc.

[0005] In Patent Document 3, a fiber performance testing mechanism is disclosed, and a shock absorbing device 40 for optical fiber vibration is disclosed, but the shock absorbing device 40 is provided independently, and the shock absorbing device is only a simple cylinder type The structure cannot be well matched with the reel for shock absorption, and the structure is complex, and the optical fiber enters the shock absorbing device along the axis of the reel. The main problem to be solved is that after the optical fiber is released along the axis of the reel, The shock absorption is performed when the vibration occurs due to the torsion generated by the torsion, and the problem of the vibration generated by its own gravity is not considered when the optical fiber is released along the direction perpendicular to the axis of the reel due to the long distance of the optical fiber arrangement. Considering the vibration problem caused when the optical fiber moves laterally on the reel due to laying, more importantly, its shock absorption effect is not very good

At the same time, the shock absorbing device 40 can only perform shock absorption for optical fibers with a specific diameter, but cannot perform shock absorption for optical fibers with larger diameters, or for optical fibers with smaller diameters, the shock absorption effect is not good.
