Description
Technical field
The present invention relates to overhead transmission line regulating device technical field.
Background technology
Traditional optical cable installation stringing, it is the sag degree with one group of fixed pulley adjustment optical cable, need many people to coordinate when operation, firmly pulling rope, just can meet the requirements of sag degree, complicated operation through repeatedly adjusting, 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 adjustment optical cable sag degree, although laborsaving, because Lever Blocks is heavier, volume is also comparatively large, brings very big inconvenience to carrying and construction usage.
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 to clamp wire, carries out stringing adjustment, easily damage optical cable, be unsuitable for optical cable installation stringing.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of optical cable tightener, and to optical cable fanout free region, and structure is simple, easy to use, is particularly suitable for 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 tightener, 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, described rope sheave is wound with wire rope, and the free end of described wire rope is fixed with traction hook, mounts with preformed armor rods strain clamp.
Described traction hook is anti-run safety hook.
The right-hand member of described link is provided with fixing link, and described wire rope is provided with travelling block, and travelling block is between traction hook and fixing link.
Described travelling block is provided with anti-run safety hook.
Described spanner is ratchet spanners.
Also be provided with the rope sling mounted with fixed hook, rope sling is the wire rope of one two the equal bands of free end.
The beneficial effect adopting technique scheme to produce is: the present invention adopts preformed armor rods strain clamp and optical cable to be intertwined and connected, and to optical cable fanout free region, and structure is simple, easy to use, is particularly suitable for 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 by existing turnbuckle and forms, remove fixing-line device part, be provided with traction hook in the end of wire rope free end, when the tractive force that erecting optical cables circuit is shorter, bear is little, the end of optical fiber strain insulator preformed armor rods directly hung on traction hook; When lightguide cable link is longer, tractive force is very large, traction hook is hung on fixing link, 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 feature of operating environment.

Mark in figure: 1-fixed hook; 2-link; 3-wire rope; 4-rope sheave; 5-spanner; 6-preformed armor rods strain clamp; 7-draws hook; 8-travelling block; 9-fixes link; 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, described rope sheave 4 is wound with wire rope 3, the free end of described wire rope 3 is fixed with traction hook 7, and mount with preformed armor rods strain clamp 6, the right-hand member of described link 2 is provided with fixing link 9, described wire rope 3 is provided with travelling block 8, and travelling block 8 is between traction hook 7 and fixing link 9; Also be provided with the rope sling 10 mounted with fixed hook 1, rope sling 10 is the wire rope of one two the equal bands of free end.
Described travelling block 8 is provided with anti-run safety hook, and described traction hook 7 is anti-run safety hook, uses anti-run safety hook can prevent the object hung thereon from coming off.
The present invention is improved by existing turnbuckle and forms, remove the fixing-line device part of existing turnbuckle, adopt fixing link 9, travelling block 8 and traction hook 6, be intertwined by means of preformed armor rods strain clamp 6 and optical cable, avoid and directly contact with optical cable and the optical cable breakage that causes, can be good at protection optical cable; At the free end of wire rope 3, grafting one becket bridle, be used for mounting traction hook 6, arrange sleeve pipe in plugging position, because the position of wire rope 3 grafting can be jagged, sleeve pipe plays the effect of protection operating personnel; Flexible steel cable or oil thread rope can be selected, be convenient to bending operation.
Preformed armor rods strain clamp structure is simple, is easy to install, easy to use, just free-handly rapidly can complete installation by a people; Stable performance, still can normally run at the environment running into extreme, grip never discharges, without harmful stress concentration point, it can reduce dynamic stress, prevents from disconnected stock phenomenon occurs because of fatigue of materials, preformed armor rods strain clamp itself has certain anti-vibration functions, the resistance to ability of shaking of wire can be improved, can ensure that strain clamp itself can not produce and the hurtful stress of optical cable is concentrated, thus ensure the ordinary life of fiberoptic cable system.
Utilize wire rope 3 to make a rope sling 10, the collar is all with in its two ends, and in use, firmly fixture is as stiff end to select one at the construction field (site), and above rope sling 10 is enclosed within, 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 are closely intertwined, and traction hook 6 hangs on preformed armor rods strain clamp 6, and rotating spanner 4 can carry out stringing operation to optical cable, simple and quick, safe, reliable and convenient, reduce labour intensity, improve operating efficiency.
Embodiment 2:
Embodiment 2 is with the difference of embodiment 1: during use, traction hook 6 is hung on fixing link 9, hangs on the hook of travelling block, utilize travelling block labour-saving principle by preformed armor rods strain clamp 6, reduce labour intensity, increase work efficiency.
General lightguide cable link adjustment operation, embodiment 1 can meet the requirement of use, and when needing, the optical cable of adjustment is longer, when tractive force is larger, adopts embodiment 2 more suitable.
The present invention is lightweight, volume is little, be easy to carry, and to optical cable fanout free region, is particularly suitable for the mobility of optical cable installation and the diversity feature of operating environment.
