Abstract

The present invention relates to the technical field of electric installation equipment, and provides a corner pay-off block, which includes a bracket, a pulley fixed on one side of the bracket, and a fixing device arranged on the other side of the bracket; There are two guide pulleys and supporting pulleys, the guiding pulleys are provided with two, and the two guiding pulleys are respectively arranged on both sides of the supporting pulley; the fixing device includes two fixed side plates hinged together. The corner pay-off block of the present invention is simple in structure and easy to use, and the block can be fixed at the corner of the building, increasing the contact area between the block and the building, protecting the building from damage, and effectively preventing the cable from being unhooked. The included angle is adjustable, making the tackle highly adaptable.

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...
