Abstract
The utility model discloses a wire pay-off pulley for a swallow-wing crossarm, comprising a traditional wire pay-off pulley. The utility model is characterized in that a connector is arranged at the traditional wire pay-off pulley through a first bolt; the swallow-tailed base plate of the connector is provided with a hole for connecting the connector with the traditional wire pay-off pulley; through holes are respectively arranged on the swallow wings at both sides of the base plate, second bolts and nuts matched with the second bolts are arranged in the through holes respectively, a fixing hook is welded at the lower end of each second bolt; two reinforcing rib plates are welded respectively on the front surface and the back surface of the swallow-tailed base plate. When the wire pay-off pulley is used, firstly, the swallow-tailed base plate is arranged on the swallow-wing crossarm, the bolts and the fixing hooks arranged on the two swallow wings are positioned at both sides of the swallow-wing crossarm, the underside of the swallow-wing crossarm is hooked by the fixing hooks; and then the nuts are screwed down to make the fixing hooks be closely hooked on the lower flange of the croassarm; finally, the wire pay-off pulley is arranged on the swallow-wing crossarm. The wire pay-off pulley of the utility model solves the problem that the insulating layer is easily damaged when wire pay-off is operated on the swallow-wing crossarm.
Description
Technical field
The utility model belongs to the equipment of installation, maintenance, dismounting cable, the particularly device of aerial cable.
Background technology
Traditional releasing pulley is that a fixed pulley is installed on support, is provided with on a side stand and seals up a door, and at the top of support hook is installed, and the U type base that is transverse opening is arranged, the bolt that screwed hole is arranged on the U type base and cooperate with it in the bottom of support.This releasing pulley is applicable to the cross-arm of angle bar class.In use, U type spare is stuck on the angle bar, tights a bolt then, releasing pulley is fixed on the angle bar.My company introduces novel electric power equipment such as " swallow-wing cross-arm ", synthetic insulator in recent years, and is widely used in the equipment.Because " swallow-wing cross-arm " is downward bathtub construction, traditional releasing pulley can't be fixed, and novel " swallow-wing cross-arm " do not have corresponding supporting releasing pulley.Therefore in construction, lead can only be placed on and drag cunning on the cross-arm, cause the insulating barrier damage of cable like this.
The content of utility model
Do not have supporting with it coaster in order to solve " swallow-wing cross-arm ", cause cable placed on the cross-arm and stretched the meaning by the operating personnel, the problem of damage cable insulation protective layer proposes following technical scheme.
The releasing pulley of a kind of being used for " swallow-wing cross-arm ", it comprises traditional releasing pulley, its special character is to pass through the first bolt mounted connector in the bottom of traditional releasing pulley, described connector is to be useful on the hole that is connected with traditional releasing pulley on the base plate of dove-tail being, through hole is respectively arranged on the swallow-wing of base plate both sides, second bolt of its lower end welding stay hook and nut engaged with it wherein are installed, at the two sides, front and back of dove-tail base plate welding reinforcement gusset.
When using this releasing pulley, at first the base plate with dove-tail places on the swallow-wing cross-arm, make be installed in both sides, stay hook that second bolt and stay hook on two swallow-wings be positioned at the swallow-wing cross-arm be hooked in cross-arm below, fastening nut, elevator bolt make and fixedly hook the lower edge that is hooked in cross-arm then.Like this this releasing pulley is installed on the swallow-wing cross-arm.Below operation is identical with traditional releasing pulley.
The utlity model has following advantage.
Use this releasing pulley to solve the difficult problem of on swallow-wing cross-arm unwrapping wire or stringing, avoid the insulating barrier damage.Can recover traditional releasing pulley after unloading lower connector, stand good in the cross-arm of angle bar class, easy to use.
