Abstract
The utility model relates to a kind of duct optical cable laying system, its difference is: it comprises terminal draw-gear, several intermediate draw gears, dragrope, guide piece, pulley and the cable laying dish for coiling cable of giving out light, described guide piece and several intermediate draw gears are placed in adjacent each manhole shaft along lead successively, described pulley is arranged on optical cable and enters, manhole shaft of coming in and going out is sentenced and is avoided optical cable and manhole friction, the head end of the optical cable on described cable laying dish is connected with dragrope by drawing head, optical cable is guided by dragrope and is drawn by described terminal draw-gear after the propelling of described guide piece and intermediate draw gear and lays.The not easy-to-draw damage optical cable of the utility model, laying optical cable length is long.
Description
Technical field
The utility model relates to a kind of duct optical cable laying system.
Background technology
Traditional duct optical cable lay general by manpower in front dragline straw line laying optical cable, and when manually laying, length is unsuitable long, and easily causes optical cable to draw damage, and efficiency is low.
Summary of the invention
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of duct optical cable laying system, and not easy-to-draw damage optical cable, laying optical cable length is long.
For solving above technical matters, the technical solution of the utility model is: a kind of duct optical cable laying system, its difference is: it comprises terminal draw-gear, several intermediate draw gears, dragrope, guide piece, pulley and the cable laying dish for coiling cable of giving out light, described guide piece and several intermediate draw gears are placed in adjacent each manhole shaft along lead successively, described pulley is arranged on optical cable and enters, manhole shaft of coming in and going out is sentenced and is avoided optical cable and manhole friction, the head end of the optical cable on described cable laying dish is connected with dragrope by drawing head, optical cable is guided by dragrope and is drawn by described terminal draw-gear after the propelling of described guide piece and intermediate draw gear and lays.
Contrast prior art, beneficial features of the present utility model is:
1), this duct optical cable laying system comprises several intermediate draw gears and terminal draw-gear, and tractive force is strong, and laying optical cable length is longer, and when laying, optical cable has multiple stress point and is evenly distributed, not easy-to-draw damage optical cable;
2), come in and go out man-hole opening place be provided with pulley, avoid optical cable and manhole frictionally damage optical cable.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the utility model embodiment using state figure;
Wherein: 1-terminal draw-gear, 2-intermediate draw gear, 3-dragrope, 4-guide piece, 5-pulley, 6-optical cable, 7-cable laying dish, 8-manhole shaft, 9-drawing head.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail below by embodiment.
Please refer to Fig. 1 and Fig. 2, the utility model embodiment duct optical cable laying system, it comprises terminal draw-gear 1, several intermediate draw gears 2, dragrope 3, guide piece 4, pulley 5 and the cable laying dish 7 for coiling cable 6 of giving out light, described pulley 5 is arranged on optical cable 6 and enters, manhole shaft 8 of coming in and going out is sentenced and is avoided optical cable 6 and manhole friction to cause wearing and tearing, described guide piece 4 and several intermediate draw gears 2 are placed in adjacent each manhole shaft 8 along lead successively, the head end of the optical cable 6 on described cable laying dish 7 is connected with dragrope 3 by drawing head 9, optical cable 6 is guided by dragrope 3 and is drawn by described terminal draw-gear 1 after the propelling of described guide piece 4 and intermediate draw gear 2 and lays.
Please refer to Fig. 1 and Fig. 2, the utility model embodiment comprises multiple intermediate draw gear 2, avoid tradition lay in the stressed situation of only optical cable 6 head end, ensure that optical cable 6 uniform force, avoid optical cable 6 to lay and middlely drawn damage, and multiple intermediate draw gear 2 accessory terminal draw-gear 1 laying optical cable 6, laying optical cable length is longer, and optical cable 6 can avoid optical cable 6 and manhole friction to cause wearing and tearing through pulley 5 into and out of entering manhole shaft 8.
Above content is the further description done the utility model in conjunction with concrete embodiment, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the those of ordinary skill of the technical field belonging to the utility model, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
