Abstract

The utility model relates to an elevator of a lightning wire, which comprises a main beam, a fixed seat, supporting brackets, screw rods with hook, adjustable cranks, a U-type screw and a cross arm. The elevator of the lightning wire is characterized in that side walls of the two fixed seat are respectively connected with the supporting brackets, the supporting brackets are respectively connectedwith two ends of the main beam, the middle part of the main beam is fixedly connected with the upper surface of the fixed seat, the lower surface of the fixed seat is connected with the cross arm, theU-type screw is fixedly connected on the lower surface of the fixed seat, the two ends of the main beam are respectively matched and connected with the screw rods with hook, and the top ends of the screw rods with hook are connected with the adjustable cranks. The elevator of the lightning wire has the technical effects of only one person for on-pole operation, easy operation, short operation time, high wire hanging quality, simple tools and wide application range, and has more obvious effects for pole towers with large weight span and large suspension point height difference (the height difference is 100m).

Description

The lightning conducter lifter

Technical field

The utility model relates to a kind of lifter, relates in particular to a kind of lightning conducter lifter.

Background technology

Because the high suspension point lightning conducter of transmission line straight line pole is the hanging wire difficulty in construction or upkeep operation, particularly to big vertical span (500～800m), the lightning conducter model lightning conducter of big (GJ-70), its vertical load big (according to calculating its vertical load in that 3.1KN～6.1KN), the operational method of taking is in the past:

1, little pole method: promptly at lightning conducter cross-arm end with 10# iron wire colligation little pole, metal binding wire cover on little pole again, the steel wire cover connects wire grip, reaches the purpose that promotes lightning conducter by tightening up wire grip.Because lightning conducter cross-arm angle steel or support are simple, do not form truss structure, so colligation is very difficult, be difficult to firmly, and be not all energy colligations of every kind of model shaft tower, this method needs operating personnel on two bars, and the activity duration is long, and operation labor intensity is bigger.

2, method is tightened up at two ends: promptly hang up properly ground wire tortoise pawl at lightning conducter hanging point two ends, winding steel wire cover on the ground wire cross-arm again, respectively the steel wire cover is coupled together with the tortoise pawl with chain block on steel wire cover both sides at last, reach the lax purpose of hanging wire place lightning conducter by tightening up the both sides chain block.This method uses Work tool more, and the activity duration is long.

3, method pickaback: promptly two people use shoulder or bamboo thick stick that lightning conducter is lifted, and this method is only applicable to the GJ-35 lightning conducter of 110KV and following circuit, and are suitable at span less (300m with interior etc. top grade) or in reperusing.

Above-mentioned these methods, the operating personnel is many on the need bar, labour intensity is big, the activity duration is long, the scope of application is little and the normal setting that surpasses of suspension clamp installation site skew.At present, also some ground wire raiser on the market, but only be applicable to the straight line pole of certain several model, most of shaft tower is all inapplicable, and the fitting operation of the double hanging point lightning conducter of uncomfortable crossed belt duplex plate.

Summary of the invention

The purpose of this utility model is to provide a kind of lightning conducter lifter, and this lifter is used for lightning conducter is promoted, so that the hanging wire operation of suspension clamp, duplex plate, U type link and lightning conducter is installed.

The utility model is achieved like this, it comprises girder, holder, support, buckle screw mandrel, adjustable crank, U type screw, cross-arm, the sidewall that it is characterized in that two holders connects support respectively, support connects the two ends of girder respectively, the upper surface of the fixedly connected holder in middle part of girder, the lower surface of holder connects cross-arm, the lower surface of the fixedly connected holder of U type screw, the two ends of the girder buckle screw mandrel that is connected respectively, the top of buckle screw mandrel connects adjustable crank.

Technique effect of the present utility model is: the operating personnel only needs a people on the bar, operation is light, the activity duration is short, and hanging wire quality height, Work tool are easy, applied widely, and, the suspension point discrepancy in elevation big to vertical span is the shaft tower of (discrepancy in elevation 100m) greatly, and action effect is more obvious.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Girder 2, holder 3, support 4, buckle screw mandrel 5, adjustable crank 6, U type screw 7, cross-arm in the drawings, 1,

Embodiment

As shown in Figure 1, the utility model is achieved like this, it comprises girder 1, holder 2, support 3, buckle screw mandrel 4, adjustable crank 5, U type screw 6, cross-arm 7, the sidewall that it is characterized in that two holders 2 connects support 3 respectively, support 3 connects the two ends of girder 1 respectively, the upper surface of the fixedly connected holder 2 in the middle part of girder 1, the lower surface of holder 2 connects cross-arm 7, the lower surface of U type screw 6 fixedly connected holders 2, the two ends of the girder 1 buckle screw mandrel 4 that is connected respectively, the top of buckle screw mandrel 4 connects adjustable crank 5.A whole set of lightning conducter lifter weight is no more than 6.5kg, during operation, only need a cover lifter and that double offset ring spanner is got final product, need not other aids and just can realize the lifting of all kinds of lightning conducters, instrument is more single, and simple installation, and the lightning conducter method for improving is grasped easily, the operating personnel only needs 1 people on the bar, and can easily operate.Activity duration can be from adopting reducing in 30 minutes more than 2 hours of previous methods.After with lifter lightning conducter being promoted,, suspension clamp accurately can be installed on appointed positions, almost can accomplish zero error, so hanging wire quality height because lightning conducter is horizontal.

Claims

1, a kind of lightning conducter lifter, it comprises girder, holder, support, buckle screw mandrel, adjustable crank, U type screw, cross-arm, the sidewall that it is characterized in that two holders connects support respectively, support connects the two ends of girder respectively, the upper surface of the fixedly connected holder in middle part of girder, the lower surface of holder connects cross-arm, the lower surface of the fixedly connected holder of U type screw, the two ends of the girder buckle screw mandrel that is connected respectively, the top of buckle screw mandrel connects adjustable crank.
