The optical cable tightener has the advantages of being simple in structure, light in weight, small in size, convenient to carry and use, free of damage to an optical cable, capable of regulating the sag degree of the optical cable to meet a required standard with time and labor saved, reducing labor intensity, improving working efficiency, and being suitable for mobility of optical cable erection and the diversity of operation environments.
Description
Technical field
The present invention relates to overhead transmission line regulating device technical field.
Background technology
Traditional optical cable installation stringing, to adjust the sag degree of optical cable with one group of fixed pulley, when operation, need many people to coordinate, firmly pull rope, through repeatedly adjusting and just can meet the requirements of sag degree, complicated operation, waste time and energy, inefficiency, operating personnel's labour intensity is large, and is subject to the restriction of working-yard operating environment; Adopt Lever Blocks to adjust optical cable sag degree, although laborsaving, because Lever Blocks is heavier, volume is also larger, uses to carrying and construction and brings very big inconvenience.
At present, the turnbuckle that overhead transmission line stringing instrument is generally applied, easy and simple to handle, but this kind of turnbuckle is provided with fixing-line device, utilizes fixing-line device chucking wire, carries out the stringing adjustment, easily optical cable damaged, and is unsuitable for the optical cable installation stringing.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of optical cable turnbuckle, without injury, and simple in structure, easy to use to optical cable, is particularly suitable for the optical cable installation stringing.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of optical cable turnbuckle, comprise link and rope sheave provided thereon, the left end of described link is provided with fixed hook, the sidepiece of link is provided with wrench, be wound with wire rope on described rope sheave, the free end of described wire rope is fixed with the traction hook, with the preformed armor rods strain clamp, articulates.
Described traction hook is the anti-run safety hook.
The right-hand member of described link is provided with fixedly link, and described wire rope is provided with travelling block, and travelling block is at the traction hook with fixedly between link.
Described travelling block is provided with the anti-run safety hook.
Described spanner is ratchet spanners.
Also be provided with the rope sling articulated with fixed hook, the wire rope that rope sling is two equal bands of free end.
Adopt the beneficial effect that technique scheme produces to be: the present invention adopts preformed armor rods strain clamp and optical cable to be intertwined and connected, without injury, and simple in structure, easy to use to optical cable, is particularly suitable for the optical cable installation stringing.The present invention portably uses conveniently, and the sag degree that can adjust optical cable reach the required standards time saving and energy savingly, increases work efficiency, and reduces labour intensity.The present invention is improved and is formed by existing turnbuckle, remove the fixing-line device part, be provided with the traction hook in the free-ended end of wire rope, when the tractive force that the erecting optical cables circuit is shorter, bear is little, the end of optical fiber strain insulator preformed armor rods directly hung on the traction hook; When lightguide cable link is long, tractive force is when very large, and traction is hung over fixedly on link, and the end of optical fiber strain insulator preformed armor rods is directly hung on travelling block, time saving and energy saving.The present invention is lightweight, volume is little, be easy to carry, and is suitable for the mobility of optical cable installation and the diversity characteristics of operating environment.

Fig. 2 is the structural representation of rope sling;
Mark in figure: 1-fixed hook; The 2-link; The 3-wire rope; The 4-rope sheave; The 5-spanner; 6-preformed armor rods strain clamp; 7-draws hook; The 8-travelling block; 9-is link fixedly; The 10-rope sling.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Embodiment 1:
From Fig. 1 to Fig. 2, the present invention includes link 2 and rope sheave 4 provided thereon, the left end of described link 2 is provided with fixed hook 1, and the sidepiece of link 2 is provided with wrench 5, and spanner 5 adopts ratchet spanners, be wound with wire rope 3 on described rope sheave 4, the free end of described wire rope 3 is fixed with traction hook 7, with preformed armor rods strain clamp 6, articulates, and the right-hand member of described link 2 is provided with fixedly link 9, described wire rope 3 is provided with travelling block 8, and travelling block 8 is at traction hook 7 with fixedly between link 9; Also be provided with the rope sling 10 articulated with fixed hook 1, the wire rope that rope sling 10 is two equal bands of free end.
Described travelling block 8 is provided with the anti-run safety hook, and described traction hook 7 is the anti-run safety hook, uses the anti-run safety hook can prevent that the object of hanging thereon from coming off.
The present invention is improved and is formed by existing turnbuckle, remove the fixing-line device part of existing turnbuckle, adopt fixedly link 9, travelling block 8 and traction hook 6, by means of preformed armor rods strain clamp 6 and optical cable, be intertwined, the optical cable breakage of having avoided directly contacting with optical cable and having caused, can be good at protecting optical cable; At the free end of wire rope 3, the becket bridle of pegging graft, be used for articulating traction hook 6, in plugging position, sleeve pipe is set, because the position that wire rope 3 is pegged graft can be jagged, sleeve pipe plays protection operating personnel's effect; Can select flexible steel cable or oil thread rope, be convenient to bending operation.
The preformed armor rods strain clamp is simple in structure, is easy to install, and convenient the use completes installation by a people is just can be rapidly free-hand; Stable performance, still can normally move running into extremely rugged environment, grip never discharges, without harmful stress concentration point, it can reduce dynamic stress, prevents from, because of fatigue of materials, disconnected burst phenomenon occurs, the preformed armor rods strain clamp itself has certain anti-vibration functions, can improve the anti-ability of shaking of wire, can guarantee that strain clamp itself can not produce the hurtful stress of optical cable concentrated, thereby guarantee the ordinary life of fiberoptic cable system.
Utilize wire rope 3 to make a rope sling 10, the collar all is with at its two ends, and in use, firmly fixture is as stiff end near one of selection at the construction field (site), and rope sling 10 covers in the above, the collar at two ends overlaps, and hangs on fixed hook 1 of the present invention; The optical cable that will adjust and preformed armor rods strain clamp 6 closely are intertwined, and traction hook 6 hangs on preformed armor rods strain clamp 6, and rotating spanner 4 can carry out the stringing operation to optical cable, simple and quick, safe, reliable and convenient, reduced labour intensity, improved operating efficiency.
Embodiment 2:
General lightguide cable link is adjusted operation, and embodiment 1 can meet the requirement of use, longer when the optical cable that needs are adjusted, and when tractive force is larger, adopts embodiment 2 more suitable.
The present invention is lightweight, volume is little, be easy to carry, and optical cable, without injury, is particularly suitable for to the mobility of optical cable installation and the diversity characteristics of operating environment.
