Abstract
The invention discloses a pretensioner of a wedge-shaped wire clamp. The pretensioner of the wedge-shaped wire clamp comprises a rack, wherein a parallelogram-shaped four-bar mechanism is arranged at the upper end of the rack, the rack and the connecting rod of the parallelogram-shaped four-bar mechanism are connected in a closed mode, and retaining teeth are arranged on one side, facing the connecting rod, of the rack to clamp a stay wire. The pretensioner of the wedge-shaped wire clamp is further provided with a gear used for driving the rack, wherein the gear is arranged in a gear box, the rack penetrates through the gear box, and a tongue piece adjusting mechanism is arranged at the other end of the rack. The pretensioner of the wedge-shaped wire clamp further comprises a ratchet-and-pawl mechanism used for driving the gear to rotate, wherein a ratchet wheel is either coaxial with the gear directly or drives the gear to rotate through a reversing gear, a rocking handle mechanism is arranged on a ratchet shaft, a pawl is connected with a reversing switch, and the reversing switch controls the pawl to be in a working state or in a non-working state by switching a certain angle. The pretensioner of the wedge-shaped wire clamp is capable of avoiding damage to the stay wire and the wire clamp.
Description
Technical field
The present invention relates to a kind of wire clamp preloader, particularly a kind of wedge clamp preloader.
Background technology
Artificial free-hand carrying out all adopted in the at present making of power transmission and distribution pole wire, without Special assisting tool, it is not tight that simple and easy operating type so very easily causes backguy to be connected with the hyoplastron of wire clamp, be difficult to reach the technical regulation requirement, for steel strand wire are contacted with wedge clamp closely, when wedge clamp is installed, traditional method all is to adopt hammer to beat the wire clip body part, reach wire clamp pretension effect, this form of construction work is very easily destroyed the zinc coat of wire clamp, even damages wire clamp, so that wire clamp gets rusty in the running in the open air, corrosion, reduce backguy intensity, affect the line security operation.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, replace that the operating type that beats carries out and provide a kind of, contact closely, avoid backguy and the impaired wedge clamp preloader of wire clamp with wedge clamp can make steel strand wire.
A kind of wedge clamp preloader, include a tooth bar, the upper end of tooth bar is provided with a parallelogram four-bar mechanism take tooth bar as fixed lever, this parallelogram four-bar mechanism is downward under the effect of deadweight when normality, tooth bar and the connecting rod of parallelogram four-bar mechanism are in the state that closes up in the time of downwards, be provided with locking tooth to clamp backguy at tooth bar and connecting rod face in opposite directions, on the wedge clamp preloader, also be provided be used to the gear with carry-over bar, described gear is arranged in the gearcase, tooth bar passes gearcase, the other end at tooth bar is provided with the tongue piece governor motion, described tongue piece governor motion includes the U-shaped regulating block that can embed between the wedge clamp top backguy two ends, U-shaped regulating block opening down, sidewall at the U-shaped regulating block is provided with a plurality of hole of arranging along the sidewall trend downwards, trend along sidewall on another sidewall of U-shaped regulating block offers bar-shaped trough downwards, opening part at bar-shaped trough is provided with closed pin, described tongue piece regulating block also includes the pressure tongue bars, described pressure tongue bars one end is hinged in the hole of U-shaped regulating block one sidewall, opposite side can move up and down in the bar-shaped trough of another sidewall of U-shaped regulating block, described wedge clamp preloader also includes one and is used for the ratchet and pawl arrangement that driven wheel rotates, described ratchet or directly coaxial with gear, or by again driven gear rotation of tumbler gear, be provided with rocking handle mechanism at ratchet shaft, described ratchet links to each other with pole changer, and the in running order and angle of turn-off of pole changer control ratchet is in non operating state.
Wedge clamp preloader of the present invention, in use, first the tongue piece governor motion is filled between two pull wire head of the wedge clamp upper end that penetrates backguy, then upwards pull the parallel four limit row four-bar mechanisms of tooth bar upper end, so that connecting rod and the tooth bar of parallel four limit row four-bar mechanisms open, again main line in the backguy is snapped between connecting rod and the tooth bar, then shake rocking handle mechanism, just can realize tongue piece and steel strand wire tension with wedge clamp, when needs make the tooth bar return, only need to pull the pole changer of ratchet, make ratchet be in non operating state, thereby make the gear return.If it is undesirable that expose the tongue piece termination of wedge clamp, then utilize and press tongue bars to compress tongue piece.The wedge clamp preloader of this structure, simple to operate, convenient and swift, easy to carry, can not damage wire clamp during work, can also play to tongue piece the effect of compacting simultaneously.Described locking tooth refer to when its suffered pulling force larger, then locking tooth holding of backguy puted forth effort larger,
Described ratchet mechanism adopts two ratchets to be symmetrically arranged in the both sides of gearcase.
Adopt two ratchets to be arranged symmetrically with the driven gear motion, stressed symmetry, equilibrium deflection can not occur in the lifting process, so that operate steadily.
The tooth bar of described wedge 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 beaten wire clamp by iron hammer or wooden mallet and reached the pretension effect, and it is inadequate that wooden mallet beats strength, do not reach the pretension effect, and iron hammer beats and gently then destroys the wire clamp zinc coat and affect the wire clamp life-span, and is heavy then directly damage wire clamp.And the present invention has changed operational method, has replaced the pretension effect that the mode of beaing reaches wire clamp by mechanical lifting mechanism.
2, the traditional work method is because the tongue piece of wedge clamp is positioned in the middle of the steel strand wire of backguy, and limited space regulate tongue piece and have certain inconvenience, and the present invention utilizes the tongue piece governor motion can accurately regulate at any time the position of tongue piece.
3, conventional method is easy to hammer is beaten in backguy in the process of beaing, and causes backguy impaired, and this method do not exist and beat step, so effectively avoided backguy impaired.
