Description
Technical field
The present invention relates to a kind of wire clamp preloader, particularly a kind of wedge shape wire clamp preloader.
Background technology
The making of current power transmission and distribution shaft tower bracing wire all adopts manually free-hand carrying out, without Special assisting tool, such simple and easy mode of operation very easily causes bracing wire to be connected not tight with the tongue plate of wire clamp, it is difficult to reach technical regulation requirement, in order to make steel strand contact closely with wedge shape wire clamp, when installing wedge shape wire clamp, traditional method is all adopt hammer to beat wire clip body part, reach wire clamp pretensioning effect, this kind of form of construction work very easily destroys the zinc coating of wire clamp, even damage wire clamp, wire clamp is got rusty in operational process in the wild, corrosion, reduce bracing wire intensity, affect circuit safe operation.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, and provide a kind of and replace what the mode of operation beaten carried out, contact closely with wedge shape wire clamp so that steel strand can be made, avoid bracing wire and the impaired wedge shape wire clamp preloader of wire clamp.
A kind of wedge shape wire clamp preloader, include a tooth bar, the upper end of tooth bar is provided with the parallelogram four-bar mechanism that take tooth bar as fixed link, this parallelogram four-bar mechanism is downward under the effect of deadweight when normality, time downward, the tooth bar of parallelogram four-bar mechanism and connecting rod are in the state closed up, tooth bar and connecting rod face in opposite directions is provided with locking tooth to clamp bracing wire, wedge shape wire clamp preloader is also provided with the gear for driving tooth bar, described gear is arranged in gearcase, tooth bar is through gearcase, the other end at tooth bar is provided with tongue piece regulating mechanism, described tongue piece regulating mechanism includes the U shape that can embed above wedge shape wire clamp between bracing wire two ends and regulates block, U shape regulates the opening down of block, the multiple hole being provided with on a sidewall of block along the arrangement downwards of sidewall trend is regulated in U shape, another sidewall of U shape adjustment block has offered bar-shaped trough downwards along the trend of sidewall, the opening place of bar-shaped trough is provided with closed pin, described tongue piece regulates block also to include pressure tongue bars, described pressure tongue bars one end is hinged in the hole that U shape regulates block one sidewall, another side can regulate in the bar-shaped trough of another sidewall of block in U shape and move up and down, described wedge shape wire clamp preloader also includes a ratchet and pawl arrangement rotated for driving gear, described ratchet or directly coaxial with gear, or by reversing gear driven gear rotation again, ratchet shaft is provided with rocking handle mechanism, switch is connected described ratchet with turning to, turn to on-off control ratchet in running order and turn and open an angle and be in off working state.
The wedge shape wire clamp preloader of the present invention, in use, first tongue piece regulating mechanism is filled between two bracing wire heads of the wedge shape wire clamp upper end wearing bracing wire, then upwards pull the parallel four limit row four-bar mechanisms of tooth bar upper end, connecting rod and the tooth bar of parallel four limit row four-bar mechanisms are opened, again main line card in bracing wire is entered between connecting rod and tooth bar, then shake rocking handle mechanism, just can realize straining the tongue piece of wedge shape wire clamp and steel strand, when needs make tooth bar return, what only need to pull ratchet turns to switch, ratchet is made to be in off working state, thus make gear go back to position. if the tongue piece termination of wedge shape wire clamp is exposed undesirable, then pressure tongue bars is utilized to compress tongue piece. the wedge shape wire clamp preloader of this kind of structure, simple to operate, convenient and swift, easy to carry, wire clamp can not be damaged during work, tongue piece can also be played the effect of compacting simultaneously. described locking tooth refers to that then locking tooth is more big to the power that holds of bracing wire when pulling force suffered by it is more big,
Described ratchet mechanism adopts two ratchet to be symmetrically arranged in the both sides of gearcase.
Two ratchet is adopted to be arranged symmetrically with driven gear motion, symmetrical by power, balanced, lifting process there will not be deflection so that operate steadily.
The tooth bar of described wedge shape wire clamp and connecting rod adopt 65 manganese steel to make.
In sum, the present invention's following advantage compared to existing technology:
1, prior art is normally undertaken beaing wire clamp by iron hammer or wooden mallet and reaches pretensioning effect, and it is inadequate that wooden mallet beats strength, does not reach pretensioning effect, and iron hammer beats the light wire clamp zinc coating that then destroys affects the wire clamp life-span, heavy then directly damage wire clamp. And the present invention changes operational method, be instead of the pretensioning effect that the mode beaten reaches wire clamp by mechanical lifting mechanism.
2, traditional work method is positioned in the middle of the steel strand of bracing wire due to the tongue piece of wedge shape wire clamp, limited space, regulates tongue piece to there is certain inconvenience, and the present invention utilizes tongue piece regulating mechanism can accurately regulate the position of tongue piece at any time.
3, traditional method is easy to beat in bracing wire by hammer in the process beaten, and causes bracing wire impaired, and present method does not exist and beats step, so it is impaired to effectively prevent bracing wire.
