Abstract

The invention relates to the technical field of power installation equipment, and provides a corner line laying pulley. The corner line laying pulley comprises a support, a pulley fixed at one side of the support, and a fixation apparatus arranged at the other side of the support; the pulley comprises guiding pulleys and a supporting pulley which are arranged to be vertical to each other, and the two guiding pulleys are respectively arranged at the two sides of the supporting pulley; and the fixation apparatus comprises two fixation side plates hinged to each other. The corner line laying pulley is simple in structure and convenient to use, can fix the pulley at a corner of a building, enhances the contact area between the pulley and the building, protects the building from being damaged, effectively prevents a cable from unlocking and is higher in adaptability due to an adjustable included angle between the two fixation side plates.

Description

technical field [0001] The invention belongs to the technical field of electric installation equipment, and in particular relates to a corner pay-off pulley. Background technique [0002] The pay-off block is widely used in the electric power industry. It is used to extend and change the direction of cables when laying pipelines, to protect cables and reduce friction, reduce pipeline damage, and improve work efficiency. At present, in the process of unwinding power cables, the general terrain is complex, and it is often encountered that cables need to turn when passing through buildings and wells. The commonly used method is to place various corner blocks at the corners, but the existing blocks are often movable, and various types of supports need to be added during construction to fix the force on the cables, protect the blocks themselves from being pulled, and protect the cables from decoupling , to protect the building itself. The effect of this method is not ideal. Due...
