Abstract
The invention discloses a protection method used for cable rapid transmission. The center of gravity of an adjusting block is constantly positioned above a connecting rod so that tension force of cables on a cable reel is enabled to be constantly stable in traction. Meanwhile, a traction block is rotatably arranged in a rectangular groove via a universal ball, i.e. optical fibers are enabled to radially swing within a certain range so that sharp swinging of the cables caused by increasing of traction force in long distance laying can be buffered, and generation of phenomena of cable swirling and surge can be avoided.
Description
Technical field
The present invention relates to cable laying field, specifically refer to the guard method for cable fast pulldown.
Background technology
In daily life, because light is more much lower in the loss of electric wire conduction than electricity in fibre-optic conduction loss, optical fiber is used as the information transmission of long distance.Fiber optic cables are a kind of telecommunication cables, and be made up of two or more glass or plastic light fibre core, these fiber cores are positioned at the coating of protectiveness, are covered by plastic pvc outer sleeve.
In the long distance process of deployment of cable, because the dynamics of factor cable when drawing of distance can increase with the increase of distance, therefore may cause being partially damaged because imposed stress concentrates in the local of cable, easily there is surge phenomenon in cable dish exit in the cable put with duration distance, the middle part of cable and the end of cable is made to occur looping, namely probably cause the bending radius of cable to be less than 15 ~ 20 times of its external diameter, increase the possibility of the impaired fracture of optical fiber.
Summary of the invention
The object of the present invention is to provide the guard method for cable fast pulldown, ensure the quick outlet transmission of cable, avoid cable because to loop and the phenomenon of surge occurs and occurs impaired.
Object of the present invention is achieved through the following technical solutions:
For the guard method of cable fast pulldown, comprise the following steps,
(A), be placed in wire casing by the optical cable the end of a thread on cable dish, start by wire casing laying optical cable being carried out to scheduled circuit, on cable dish, optical cable distributes layer by layer, and therefore the traction of optical cable starts in layer to be drawn out according to the axis direction of cable dish;
(B), by regulating block be slidably arranged on connecting rod, regulating block starts to slide on connecting rod with the outlet direction of optical cable on cable dish, and by the adjustment to optical cable outlet, and then at the axial direction of cable dish, reduction optical cable occurs that the phenomenon significantly swung occurs;
(C), regulating block is eccentric relative to connecting rod, and namely the center of gravity of regulating block is not on connecting rod, and then ensures that the center of gravity of regulating block is in the top of connecting rod all the time;
(D) on regulating block, rotate the anti-springboard being provided with U-shaped, and the middle part of anti-springboard is connected with two end by two Flexible Connectors, when the outgoing line part of cable raises up, offer just to the deep-slotted chip breaker at wire casing center in the middle part of anti-springboard, after wire casing put into by cable, this deep-slotted chip breaker can coordinate with wire casing the entirety of cable is limited in border circular areas;
(E), guiding piece rotated by multi-directional ball and is arranged in rectangular channel, optical fiber namely can be made to realize within the specific limits radially wobbling, significantly swing to be buffered in the optical cable caused because traction dynamics increases when long distance is laid;
