Description
Technical field
The present invention relates to supply line's construction field, specifically refer to cable tight line apparatus.
Background technology
At electric power system overhead high voltage line laying construction or when making an inspection tour, the tension of high-tension line is a very important job, directly has influence on the use of whole power circuit, if pine passed by by power line, then sag is excessive, easily swings, and collision is short-circuited mutually; If power circuit tension, then easily there is broken string or line bar is broken.Usually the tension for high-tension line adopts artificial tension, but tension effect is undesirable, inefficiency, and labour intensity is also larger.What utilized instrument to realize stringing function is by fixing-line device, cable is blocked recycling lifting device traction cable to realize stringing in the past mostly, but use instrument also exists following problem in line construction and accident treatment: stringing instrument is heavy, moves inconvenience; Employment is many, complicated operation; The fixing tension device of piling, takes up an area and damages masses crops, extend interruption duration without reason.Especially larger for sag, apart from distant circuit, because cable is oversize, tool stroke is limited, cannot carry out tension by a relatively large margin, so two cover wire grips need be with to ascend a height toward contact during real operation, has more increased the weight of the labour intensity of operator.How not only to meet construction requirement but also make stringing utensil lightly nimble in accident treatment with in constructing among a small circle as far as possible, just refer in the middle of problem innovation research.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Portable type tightener, and compact structure is convenient for carrying, and tension is reliable, effectively can prevent cable from falling loose, be applicable to the occasion that tension travel is larger.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Portable type tightener, comprise lifting device, lifting device rear end is connected with fixing-line device by hook a, described lifting device includes hollow square urceolus, one tooth bar slided in urceolus is set in urceolus, urceolus front portion is provided with ratchet box, hinged one ratchet be meshed with tooth bar in ratchet box, the outer hinged one handle of ratchet box, the front ratchet of what handle front end hinged coordinated with ratchet be provided with torsionspring, the also hinged one rear ratchet being provided with torsionspring coordinated with ratchet being positioned at ratchet rear in ratchet box; The front end of described tooth bar arranges the retainer ring of the cross-arm of a connection electric pole, and retainer ring side is worked as lifting device by static line connection one and is retracted to the hook b that fixing-line device can be caught on the most in short-term;
Described fixing-line device comprises the base plate of a subtriangular structure, and one of them drift angle place arranges lower card line cover, and another drift angle is provided with slideway, the 3rd the hinged fastening connecting rod in drift angle place; Described fastening connecting rod is also approximate triangular shape, overlap hinged to overlap with lower card line in close drift angle place with described lower card line coordinate and block the upper card line cover of cable, 3rd drift angle of fastening connecting rod and one, with the pulling rod hinge connection of link, pulls in the slideway of connecting rod cross-under on base plate; Link is connected in the hole of outer tube rear end of lifting device by hook a.
The present invention improves further and is: described rear ratchet is provided with group hand rear ratchet and ratchet separated.
The present invention improves further and is: described upper card line cover and lower card line put and be provided with friction texture.
The present invention improves further and is: the length of described static line is enable the lifting device hook b be retracted on static line the most in short-term catch on the link pulled on connecting rod.
Owing to adopting technique scheme, the beneficial effect that the present invention produces is:
Structure of the present invention is simply small and exquisite, is convenient for carrying, and tension is reliable, effectively can prevent cable from falling loose, be applicable to the situation that tension travel is larger.
The lifting of cable leans on the engagement of the sour jujube wheel and rack of lifting device to realize, and often engage once engagement position and all can fix under the effect of ratchet, effectively prevent cable from falling loose, minimizing is dangerous, improves the coefficient of safety in line construction.
During operation, cable is clamped by fixing-line device, it is also larger that the power contrary with direction of improvement that fixing-line device is subject to goes up more greatly pressure between lower card line cover, along with the reverse drag force of the lifting cable of cable to fixing-line device is also increasing in operation process, also more and more tighter to cable clamp of self-locking fixing-line device.Upper card line cover and lower card line put and are provided with friction texture, provide larger frictional force, make card line more reliable in lifting process to cable.
Retainer ring connects a hook b, if lifting device is retracted to the needs that the most still can not meet stringing, after link can being caught on hook b, a set of fixing-line device circularly enhancing cable is installed again, is applicable to the occasion that tension travel is larger.The length of static line is enable the lifting device hook b be retracted on static line the most in short-term catch on the link pulled on connecting rod, the height promoted need not be sacrificed when such Design of length changes fixing-line device after making cable promoted a stroke, wire grip can be utilized to greatest extent.
