Description
Technical field：
This utility model belongs to overhead line erecting equipment, more particularly to a kind of tightener.
Technical background：
In the work such as construction, power transmission line erection, need tension positioning to be carried out to various bracing wires, electric wire, and adopt
The artificial mode work efficiency low-intensity for tensing colligation is big, and tightening force is little and cannot ensure stringing effect, therefore, special is tight
Line device is widely used in category work.
Existing tightener design adopts single-stage ratchet structure, ratchet easily to occur ratchet, ratchet after a long time use
Plastic deformation damage's problem, causes tightener to fail, while single-stage ratchet is with single-stage movable pulley attachment structure when mounted more
Arduously, not with the function of adjusting gear ratio according to job demand.
The content of the invention：
A kind of tightener goal of the invention of this utility model：There is provided and a kind of can effectively extend ratchet, ratchet service life
Tightener is designed, and allows which to need to change gear ratio according to operating mode.
A kind of tightener, including housing, ratchet, ratchet, capstan winch, hawser and hook；Wherein, ratchet fixation coaxial with capstan winch
And be arranged in housing, ratchet is arranged in housing and is contacted with ratchet, and hawser is connected with hook after being drawn by capstan winch, ratchet shaft
On be provided with crank socket；Ratchet includes at least two contact platforms, and is arranged in same connecting shaft.Set by multiple ratchets
Meter, on tightener ratchet provides multiple work surfaces simultaneously, script is split in multiple works by the pressure that single hook tooth undertakes
Make on face, reduce the stress of single hook tooth, prevent, slow down the generation of plastic deformation, improve its service life.Crank and stringing
Device is disassembled socket type connected mode, and when tightener works, such as inconvenient midway is removed, then can a dismounting crank,
Main tightener surface projection is removed, and prevents from the safety of working environment being affected because of hook personnel, equipment.
Preferably, crank shaft spigot is provided with flywheel.
Preferably, the design also includes crank gear, and the crank gear is engaged with ratchet, and which is installed axle portion and is provided with crank
Socket, provides a kind of underneath drive than selecting for tightener, allows operator as needed from laborsaving by crank gear
Working method.
The design can also include hook capstan winch, and hook capstan winch is installed on capstan winch side and is provided with flywheel, and hawser is from strand
Disk is drawn and is connected with hook after hook capstan winch.Hook capstan winch flywheel is servo-actuated when tightener is installed and does not cause additional friction, inverse
When dynamic flywheel braking make hawser can only opposed member capstan winch slide, so as to reduce tightener remove when payingoff speed, improve behaviour
Make safety.
Preferably, also including hook movable pulley, on hook, hawser around hook movable pulley and draws from after capstan winch extraction
Return and be fixed on housing, provide a weight optional effort-saving mechanism more.
Preferably, also side is linked up with including hook fixed pulley installed in housing, hawser is from after capstan winch extraction in hook movable pulley
Continuously detour between hook fixed pulley, end is fixed on housing；Further, link up with fixed pulley for multiple, coaxial installation with
Improve the pulling force that tightener can be used.
A kind of beneficial effect of tightener of this utility model：Designed by assembly pulley and crank design of gears passes tightener
Dynamic ratio can be adjusted as needed, effectively reduces payingoff speed by linking up with capstan winch, improves safety in utilization, and with multiple ratchets
The structure of contact platform increases service life of equipment.
