Description
Technical field
The present invention relates to wire grip, particularly a kind of wire grip that on a kind of transmission line, operation uses, it is applicable to the operation of large load implement.
Background technology
Along with technical development, on ultra-high-tension power transmission line, on the high tower of particularly some long-span electric transmission line, the equipment adopted is all the implement of large load, long span super high town design in such as 220kV high standing grain I, II road adopts the leap mode of strain insulator-straight line-straight line-straight line-straight line-strain insulator, and engineering wire adopts two division extra-heavy shaped steel core aluminium alloy wire (in anticorrosion), sectional area S=729.0mm2, outside diameter d=35.1mm, calculated mass G=3297 ㎏/㎞; The every phase suspension string of high tower adopts the two string composition of 22 FC400/205, and monolithic glass insulator structure height is 205mm, and insulator string is long is 4510mm, insulator string assembled height 5685mm, and insulator string gross mass is 308 ㎏.Equipment due to these large loads is the several times of common line, and common live line working wire grip is stressed too large, and operating difficulties, cannot carry out valid function to this equipment, considerably increase the labour intensity of operating personnel, and operating efficiency be extremely low.
Summary of the invention
The object of the invention is to provide according to the deficiencies in the prior art part a kind of easy to operate, wire grip of reducing labour intensity, increasing work efficiency.
The object of the invention is to be realized by following approach:
Wire grip, its structural feature is, includes outer loop bar, nut sleeve, screw rod, operating grip, adjustment means, fixed mount and gear train; Outer loop bar comprises upper boom and lower beam, and nut sleeve is positioned at the inner chamber of outer loop bar, through whole outer loop bar, and screw rod is arranged in nut sleeve inner chamber, and two ends expose to outside nut sleeve, and is respectively arranged with the first connecting portion and the second connecting portion; Adjustment means includes the cross bar that is connected with operating grip and is positioned at the connecting rod of crossbar end perpendicular to cross bar, connecting rod and the T-shaped structure of cross bar, connecting rod is a kind of ratchet mechanism, and corresponding crossbar end is a kind of detent mechanism, and the two connects to form click component; The two ends of connecting rod are respectively fixedly connected with lower beam with upper boom respectively by one group of fixed mount; Gear train includes intermeshing driving wheel and driven pulley, and wherein driving wheel is diameter comparatively pinion, and driven pulley is larger diameter gear, driving wheel is arranged on the side of connecting rod, between cross bar and fixed mount, driven pulley, between upper boom and lower beam, is fixedly connected with nut sleeve.
During use, rotate adjustment means by operating grip, and drive the driving wheel be positioned on connecting rod to rotate, driving wheel drives driven pulley to rotate further, driven pulley drives nut sleeve to rotate, thus the screw rod being positioned at nut sleeve inner chamber is moved up and down, and operates to coordinate other insulating tools; Wherein said click component can make adjustment means drive connecting rod to be one-directional rotation.Because wire grip of the present invention is for promoting or length between change equipment and distance, especially outer loop bar is separated, nut sleeve is exposed to install gear wheel in centre, then pinion is adopted to drive the mode of gear wheel, the speed ratio of adjustment gear wheel and pinion can save operation firmly greatly, make operation more convenient, laborsaving, greatly reduce the labour intensity of operating personnel, improve operating efficiency.
The present invention can be specially further:
The position that the upper boom of nut sleeve loop bar is outside relative with lower rod end surface is provided with spacing preiection.
Like this, this spacing preiection for limiting upper boom and the relative position of lower beam in nut sleeve, meanwhile, for driven pulley provides enough and reliable safe space.
Screw rod comprises screw rod and lower screw rod, upper screw rod is positioned at a side of nut sleeve inner chamber, the one end exposing to nut sleeve connects the first connecting portion, lower screw rod is positioned at another side of nut sleeve inner chamber, the other end exposing to nut sleeve connects the second connecting portion, and upper screw rod is rightabout screw thread with the internal thread of the nut sleeve that the corresponding spiral of lower screw rod connects.
Like this, about two counterscrew be screwed with nut sleeve can under the drive of nut sleeve, simultaneously to outside two of nut sleeve or medial movement, thus produce the flexible change of axis, the power tightened up or loosen can be provided when replacing insulator under electrified, be convenient to the insulator string promoting large load.Screw rod is divided into two sections, singe screw compared to existing technology, can when nut sleeve provides same rotating distance, obtain the stroke of double screw rod, thus obtain double stroke distances, like this, under the prerequisite needing same stroke distances, only need the stroke operating rotating nut cover half, make further to operate more laborsaving convenience.
Further, the one end being positioned at nut sleeve inner chamber at upper screw rod and lower screw rod is provided with retaining pin, corresponding is provided with spacing hole slot inside the both ends of nut sleeve, spacing hole slot and retaining pin suitable.
Because screw rod is divided into two, therefore its total travel is also shorter, for preventing screw rod from use deviating from nut sleeve, preferably installs retaining pin, and the processing safety of instrument is protected.
The present invention can also be specially further:
In adjustment means, be provided with a cuphead pilotage in cross bar, the ratchet in detent mechanism is withstood in this cuphead pilotage one end, and the other end is connected to by a spring and the hold-down screw that is connected with spring the end that cross bar is connected with operating grip.
Cuphead pilotage is used for ratchet to engage with ratchet reliably, ensures the reliability of operation.
In sum, the invention provides a kind of wire grip, it is for promoting or length between change equipment and distance, especially outer loop bar is separated, exposes nut sleeve in centre to install gear wheel, then adopt pinion to drive the mode of gear wheel, the speed ratio of adjustment gear wheel and pinion can save operation firmly greatly, make operation more convenient, laborsaving, greatly reduce the labour intensity of operating personnel, improve operating efficiency.
