Optical cable stress-free retractable device

Abstract

The invention relates to an unstressed winding and unwinding device for an optical cable. The unstressed winding and unwinding device comprises a base arranged on the ground, a star-shaped bracket, an optical cable end fixing mechanism and a plurality of universal wheels, wherein the star-shaped bracket is rotationally arranged on the base, a plurality of hollow primary rods are uniformly distributed on the star-shaped bracket in the direction from the rotary center to the periphery, secondary rods are inserted into the primary rods, insertion holes are formed in the primary rods and the secondary rods respectively, a pin rod is inserted into a pin hole in each secondary rod outside each primary rod, and pin rods for limiting the inner ring of the optical cable are inserted into a pair of pin holes in the coincident part of the primary rod and the secondary rod; the optical cable end fixing mechanism is connected to the longitudinal side surface of the one primary rod. According to the unstressed winding and unwinding device, the pin rods are arranged on the star-shaped bracket with the primary rods and the secondary rods, so that the commonality of operation of winding and unwinding optical cables with different specifications is improved; the end fixing mechanism is arranged, so that the end of the optical cable can be firmly limited in the corresponding position of the star-shaped bracket as needed during cable winding, and the working efficiency of initial cable winding operation is improved.

Description

technical field [0001] The invention relates to the field of optical cable production equipment, in particular to an optical cable stress-free retractable device. Background technique [0002] At present, when selling short and long optical cables, in order to ensure the consistency of the optical cable winding, the optical cable needs to be wound on the optical cable reel first, and then removed from the optical cable reel, which consumes a lot of manpower and occupies production equipment. In addition, the optical cable samples sent by the existing production department for inspection are manually wound, and the winding radius of each turn is inconsistent, so the existing tools cannot be used for cable laying operations. During the inspection, it is completely necessary to rely on manual laying of the cable, which is time-consuming and labor-intensive. Due to the different sizes of optical cables, the position of the inner ring of the optical cable changes, and the fixed ...

Problems solved by technology

[0002] At present, when selling short and long optical cables, in order to ensure the consistency of the optical cable winding, the optical cable needs to be wound on the optical cable reel first, and then removed from the optical cable reel, which requires a lot of manpower and occupies production equipment.

In addition, the optical cable samples sent by the existing production department for inspection, because they are manually wound, the winding radius of each turn is inconsistent, and the existing tools cannot be used for cable laying operations

During the inspection, it is completely necessary to rely on manual cable laying, which is time-consuming and laborious

Due to the different sizes of optical cables, the position of the inner ring of the optical cable changes, and the fixed position of the cable end must also be adjusted according to the above-mentioned requirements during the cable winding operation. The existing cable winding operation usually uses adhesive tape to paste the end of the optical cable. On the cable take-up device, the connection strength is very low, so that the initial part of the cable take-up operation must be carried out at a slow speed to prevent the end of the optical cable from falling off; The process is accompanied by an eccentric pulling force tangential to the outer ring of the optical cable, which makes the cable receiving device prone to deformation after long-term operation, which affects the winding quality of the optical cable and reduces the service life of the cable receiving device
