Abstract

The utility model relates to a wire paying out and replacing butt connector, which is an instrument used for the construction of a distribution line and a transmission line for the high voltage and the low voltage of an electric power line. Two ends of the utility model is connected with a steel rope, and the utility model is composed of a locking wire sleeve, an outer cone sleeve, an inner cone, a fastening bolt, and a steel rope sleeve. Because the outer cone sleeve and the inner cone core are in taper, the more the outer cone sleeve and the inner cone core are pulled, the more tightly the outer cone sleeve and the inner cone core are. The butt connector can joint two ends of the wire end-to-end as integration. The utility model is soft and elastic, is convenient to construct, can pass through a block smoothly, provides convenience for electric power constructors who work high above the ground, alters an original method for mismatching and bounding two ends of the wire in the past, enhances construction quality and efficiency, saves time, and ensures personal safe.

Description

Lead unwrapping wire docking adapter

The utility model relates to a kind of lead unwrapping wire docking adapter, and genus electric power system high pressure, low pressure are set up distribution line, power transmission sequence, a kind of instrument of using when unwrapping wire, thread-changing.

At present, at electric power system wire erection unwrapping wire, in the process of thread-changing, owing to there is not docking adapter, adopt original method to operate always, therefore exist some shortcoming and defect: with two terminals colligation is connected, like this, rough greatly again and smooth because of diameter of wire, lead is sliding excessively again etc., and difficulty is difficult for tying solid; Operating personnel's upper boom is seen slider, not only labor strength is big, and the operating time is long, and definite operating personnel's personal safety is not had reliable guarantee, and coefficient of safety is poor.

The purpose of this utility model provides a kind of assurance operating personnel personal safety, and is simple in structure and can increase work efficiency high-low pressure lead unwrapping wire docking adapter.

The purpose of this utility model can realize by following technical proposals, it is the external conical sleeve that is connected two ends by steel cable, in the external conical sleeve is cone-shaped cavity, in the inner cone core body that is slidingly matched is arranged, the two tapering face direction contact, Inner awl core is to be clear opening in the middle of the opening, make it to have elastic force and tighten, be with fastening bolt at steel wire rope with the steel wire rope junction, have external screw thread, the steel wire rope termination of the front of screw thread is welded with steel wire loop and the fastening bolt inner hole wall is slidingly matched, the other end at the locking wire cover has the reducing step, has external screw thread on the step, external conical sleeve has internal thread and is threaded with it, locking wire cover endoporus has step for leading directly to, two sides have through hole on the jacket wall of locking wire cover, lead is to insert locking wire cover intermediate throughholes to seal in the inner cone core intermediate throughholes, the locking wire cover all is that the corresponding conical surface matches with external conical sleeve and inner cone core, lead is also fastened after tight can not at will move within it when the spiral shell of the fastening bolt of steel wire rope and locking wire cover is buckled, the scarce hole that locking wire puts is played pin for the chucking lead and is used, having afterburning hole on the fastening bolt is after such lead is docked, the lead that this docking adapter and its are connect can pass through on pulley smoothly, is unlikely stuck on pulley and influence efficiency of construction.

The utility model compared with prior art, because it is simple and reasonable in generation of the present utility model, easy to operate, safe and reliable, in light weight, be easy to carry, high efficiency, changed the bind method of past lead misfit when the unwrapping wire thread-changing, do not need the operating personnel to go up electric pole yet and see slider, minimizing personnel upper boom number of times, calculating every basic electric pole by lead frame high 10 basic electric poles and save 3 minutes than in the past and equal to save 30 minutes, also saved the material of wiring, is the ideal tools of electric power system stringing, unwrapping wire, thread-changing.

Accompanying drawing is the utility model structural representation.

1--locking wire cover, 2--inner cone core, 3--steel wire loop, 4--fastening bolt, 5--steel wire rope, 6--external conical sleeve, the afterburning hole of 7--, 8--locking wire trepanning.

Specifically describe embodiment of the present utility model in conjunction with the accompanying drawings.

The locking wire cover (1) of docking adapter as shown in drawings, external conical sleeve (6), inner cone core (2), steel wire loop (3) 45 ^*Steel, the housing outside is zinc-plated, it all is that taper tapering face direction contacts that the interior clam of the jagged son of inner cone core has screw thread external conical sleeve and inner cone core, cooperation can slide over each other, its butt joint connector is a steel wire rope, the big safe and reliable and soft flexible constructing operation of being convenient to of tension coefficient, locking wire put to be had microscler through hole and is used for tightening.

But locking wire cover fixing cord makes the line can clamping wire at smooth operation inner cone core, and the awl core is jagged, and steel wire loop is used for fixing head end of steel wire rope, and external conical sleeve is in order to fixing inner cone.

This docking adapter is applicable to the High-Voltage Insulation line, steel core aluminium hinge line, aluminium hinge line, copper hinge line.Still wire erection, unwrapping wire, thread-changing, old tape ew line, two head end conductor cross-sections are not equal, and the lead of different size is furnished with the docking adapter of different size for this reason.

Using method, in the unwrapping wire process, earlier docking adapter holding screw, locking wire cover unclamp, lock tube Inner tapered sleeve, seal in certain position in order from the lead head end, screw tight the lock tube set bolt then, two ends are adjusted identical, accent finishes and can carry out unwrapping wire.

Claims

1, a kind of lead docking adapter, it is characterized in that: by steel cable connect two ends be cylindric in for the inner conical sidewall of external conical sleeve (6) external conical sleeve (6) of cavity and cone-shaped and tapered core tapering contact-making surface for being slidingly matched, the centre is a clear opening, external conical sleeve on the steel wire rope of one on steel wire rope, have fastening bolt (4) with external conical sleeve be threaded, steel wire loop (3) that a weldering of steel wire rope is an one can contact with the termination that Inner bores core, reducing place of the other end of external conical sleeve (6) or step place have screw thread and are connected with the external screw thread of its conical locking wire cover (1).
