Description
Technical field
The invention belongs to the power transmission and transformation technical field, particularly make somebody a mere figurehead the Line tool of holding that uses when electric wire or cable are installed.
Background technology
In the power transmission and transformation line construction, vigorously advocate equalization of strain unwrapping wire method.In construction for the safe distance of equalization of strain after guaranteeing lead and pulling equipment being connected and circuit scissors crossing, just wire fastening device without wire outlet, haulage cable must be installed in lead, the correct position on the ground wire, promptly this point is more than 1.2 times of iron tower height to the distance of iron tower, it could be landed connection like this.Originally all be to remove to install wire fastening device without wire outlet by the method that the workman climbs out of lead wire and earth wire (promptly hang coaster, advance along lead), operating personnel's safety is difficult to guarantee that waste time and energy, operating efficiency is low, influences construction schedule.
Content of the present invention
Use original wire fastening device without wire outlet to waste time and energy in order to solve, the problem that operating efficiency is low proposes following technical scheme.
A kind of wire fastening device without wire outlet, its special character is respectively to open a gap 3 at the two ends up and down of substrate 5, be provided with pedestal 2 in the both sides of breach 3, by the axle on the pedestal 21 pulley 4 is installed, pass through first bolt 18 and second bolt 7 mounting groove clevis plates 19 respectively in the both sides, bottom of substrate 5, the other end of clamping plate 19 is installed the fixture block 12 that its inner surface is the face of cylinder respectively by the 3rd bolt 13 and the 4th bolt 9, the outside of clamping plate 19 is provided with on it, there is the gusset 15 in first hole 14 and second hole 16 at following two ends, main closing hook 6 is installed on first bolt, 18 tops, by bearing pin 8 secondary closing hook 17 is installed on the main closing hook 6, main, the mouth of hook direction of secondary closing hook is opposite, all overlap mutually with second bolt 7, and use nut check, on the top of the 3rd bolt 13 flexible closing hook 11 is installed, the opening of flexible closing hook 11 and the 4th bolt 9 overlap joints, closed.
Above-mentioned bolt all can replace with bearing pin, and why adopting bolt is to be convenient to use the nut check closing hook.The inner surface of fixture block 12 is the recessed face of cylinder, is processed with impression on it, so that fully contact with lead and increase static friction power.For damage wires not, fixture block 12 is made by aluminium alloy, and pulley 4 is made of copper.
When using this wire fastening device without wire outlet to remove lead wire and earth wire, the operating personnel opens the closing hook on the wire fastening device without wire outlet before the strain insulator power string bottle of iron tower, and lead is placed in the wire fastening device without wire outlet, makes pulley be close to lead, again with the closing hook closure, so wire fastening device without wire outlet is installed on the lead.The two ends of a steel wire rope are tied up to respectively on first hole 14 of two gussets 15, tie up to the mid point of above-mentioned steel wire rope again with an end of another steel wire rope, the other end links to each other with pulling equipment after passing the fixed pulley that is fixed on iron tower or the earth anchor, fastens two ropes respectively on second hole 16 of two gussets 15.Spur rope by the Ground Operation personnel then, wire fastening device without wire outlet is draged assigned address.Ground afterwards personnel unclamp rope, and the pulling equipment haulage cable lands lead wire and earth wire and is connected with the tension force pulling equipment, after tension stringing equipment is stressed, unclamps haulage cable, and steel wire rope is not stressed.At this moment the ground staff along draging perpendicular to the direction of substrate longitudinal axis, promptly to two laybacks, opens two ropes with clamping plate 19, and fixture block 12 breaks away from lead.With rope wire fastening device without wire outlet is draged then and get back to the iron tower place, closing hook is opened, wire fastening device without wire outlet is removed from lead by the operating personnel.The using method of this wire fastening device without wire outlet is same as described above during tight hanging wire.
Use this wire fastening device without wire outlet, the operating personnel needn't climb out of lead, just can install or remove wire fastening device without wire outlet at the iron tower place, and is time saving and energy saving, improved operating efficiency greatly.
