Multipurpose on-tower pulley hanger

Abstract

The invention discloses a multipurpose on-tower pulley hanger for hanging a pulley on a tower during guide line spreading of high-tension transmission lines. The multipurpose on-tower pulley hanger comprises an outer bending plate, an inner bending plate, an inclined bending plate and four hang points. The outer bending plate and the inner bending plate are two angle-steel-shaped 90-degree bending plates, third hang points are welded on a plane of an outer side of the outer bending plate, fourth hang points are welded at a symmetrical center of the outer side of a bending, and second hang points are welded on a plane of the inner side of the inner bending plate. Two ends of the inclined bending plate bend inwardly and symmetrically, bending angles are both 135 degrees, and first hang points are welded at a symmetrical center of a plane of the inner side of the inclined bending plate. Each hang point is composed of two hang plates with the same structure, and connecting holes are arranged on end portions of the hang plates so as to form an integral hang point. Three hang plate end portions are all provided with the connecting holes through bolts and nuts, and are connected integrally and are fixed on an iron tower angle steel. Due to the fact that opening directions of angle steel planes on an iron tower may be different, only one of the hang points is needed to be selected during hanging connection, so that hanging connection of the pulley can be achieved.

Description

technical field [0001] The invention belongs to an auxiliary tool for hanging a wire pulley on an iron tower when a wire is deployed during the construction of a high-voltage transmission line, and in particular relates to a multi-purpose pulley hanger on a tower. Background technique [0002] When laying out wires during the construction of high-voltage transmission lines, the wire pulley must be suspended on a horizontal component angle steel of the iron tower. The existing technology generally adopts two suspension methods. Forming a hanging point, this method is not only poor in safety, but also the hanging point may shift when the wire is laid out. The second is to punch holes on the angle steel to form hanging points. This method is both troublesome and unsafe when punching holes at high altitude. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and propose a multi-purpose tackle hanger on the ...
