Abstract
The utility model relates to a multi-purpose overturning sheave pulley, which solves the problem that as no sheave pulley is matched with the swallow-wing cross arm, the cable is arranged on a cross arm to be manually drawn, thereby damaging the main insulation protection layer of the cable. The multi-purpose overturning sheave pulley is characterized in that a pulley frame is arranged on a main plate, the middle of the pulley frame is provided with a pulley through a pulley shaft, the upper part of the pulley frame is provided with a through hole, an anti-falling pin is inserted in the through hole and jacket with a roll sleeve, a positioning bolt is arranged under the main plate and movably jacketed with a fixing clamp plate, the lower end of the positioning bolt is provided with a locking nut, and limit clamps are welded under the two sides of one end of the main plate. When being used, the utility model can prevent the direct abrasion of the cable and the cross arm to damage the insulation protection layer of the cable, save the labor, and improve the working efficiency. Moreover, the utility model is applicable to the swallow-wing cross arm and also various types of cross arms.
Description
Technical field
The utility model belongs to the equipment that is used to install, safeguard, repair or dismantle cable, particularly is used for the device of drum cable.
Background technology
Panjin electric company introduced novel electric power equipment such as swallow-wing cross-arm, synthetic insulator in 2007, and widely applied in the equipment.Because swallow-wing cross-arm profile is special, top not supporting with it towards the sky coaster, therefore in setting up the tight payingoff construction process of distribution line, the lead of dispensing can only be placed on the cross-arm and rub, the workmen stands on the ground and stretches the meaning.Main insulation protective layer to suspended insulated guide wire has caused permanent damage like this.
Content of the present utility model
Not have supporting with it coaster in order solving at the swallow-wing cross-arm, to cause cable placed on the cross-arm and stretched the meaning by the people, the problem of damage cable main insulation protective layer proposes following technical scheme.
A kind of use towards the sky coaster more, its special character is an installation pulley yoke on mainboard, pulley is installed by pulley spindle in the middle part of pulley yoke, top at pulley yoke is provided with through hole, wherein inserts the anticreep pin, and locking pin nails on the suit roll sleeve, installing and locating bolt below mainboard, movable set strap on the bolt, there is locking nut the lower end of bolt, welded limiting card below end both sides of mainboard.
Use in the time of to use towards the tight payingoff construction of sky apparatus for suspension establishing electric line more, at first two spacing cards below the mainboard are ridden on the swallow-wing cross-arm, then bolt is inserted in the middle pin insulator jack of swallow-wing cross-arm, strap is enclosed within on the bolt that passes the swallow-wing cross-arm, and make strap be close to the lower surface of swallow-wing cross-arm, use nut screwing clamping afterwards, will use towards the sky coaster like this to be fixed on the swallow-wing cross-arm more.Extract the anticreep pin then, cable is placed on the pulley, and then insert the anticreep pin, when inserting the anticreep pin, roll sleeve is enclosed within locking pin and nails on, so that reduce friction between cable and the anticreep pin.The purpose of doing like this is to prevent that cable from coming off from pulley yoke.
In setting up the tight payingoff construction process of distribution line, use to use towards the sky coaster more and can avoid cable directly to contact friction, damage the cable insulation protective layer with cross-arm, and laborsaving, increase work efficiency.
Should use more and not be only applicable to the swallow-wing cross-arm, and can on existing all kinds cross-arm, use towards the sky coaster.

Embodiment
Embodiment
A kind of use towards the sky coaster more, because it is wide that the swallow-wing cross-arm is an end, the other end is narrow, therefore should use also correspondingly towards the shape of the mainboard 4 of sky coaster more, present an end roughly rectangle wideer than the other end, three groups of pulley yokes 6 are installed above mainboard 4, by pulley spindle 7 pulley 8 are installed at the middle part of every group of pulley yoke 6.In order to prevent that cable from coming off from pulley yoke, be provided with through hole on the top of pulley yoke 6, wherein insert anticreep pin 9.In order to reduce the friction between anticreep pin 9 and the cable, suit roll sleeve 10 thereon when inserting anticreep pin 9.Installing and locating bolt 3 below mainboard 4, suit strap 2 on the bolt 3, strap 2 can move up and down along bolt 3, is combined with nut 1 in the lower end of bolt 3.A spacing card 5 is respectively welded in both sides below an end of mainboard 4.
In setting up the tight payingoff construction of distribution line, use in the time of to use towards the sky coaster more, at first two spacing cards 5 below the mainboard are ridden on the swallow-wing cross-arm, bolt 3 is inserted in the middle pin insulator jack of swallow-wing cross-arm then, strap 2 is enclosed within on the bolt 3 that passes the swallow-wing cross-arm, and make strap 2 be close to the lower surface of swallow-wing cross-arm, tighten with nut 1 afterwards, will use towards the sky coaster like this to be fixed on the swallow-wing cross-arm more.Extract anticreep pin 9, cable is placed on the pulley, and then insert anticreep pin 9, when inserting anticreep pin 9, roll sleeve 10 is enclosed within locking pin and nails on 9, so that reduce the friction between cable and the anticreep pin 9.Use to use towards the sky coaster more and can set up three cables simultaneously.
Claims (1)
1, a kind of use towards the sky coaster more, it is characterized in that installation pulley yoke on mainboard, pulley is installed by pulley spindle in the middle part of pulley yoke, top at pulley yoke is provided with through hole, wherein inserts the anticreep pin, and locking pin nails on cover dress Roll cover, installing and locating bolt below mainboard, movable set strap on the bolt, there is locking nut the lower end of bolt, welded limiting card below end both sides of mainboard.
