Example Embodiment

[0027] Figure 4 Shown are the structural schematic diagrams of the asymmetric traction plate and the pay-off block of the present invention.

[0028] The asymmetric traction plate of the present invention mainly includes four parts: a large guiding plate 31, a traction plate body 32, a small guiding plate 33 and an anti-twist device 34. The traction plate body 32 adopts an asymmetrical structure, and one side can be connected with two wires, and the other side can be connected with only one wire. The large guide pull plate 31 is located at the front end of the traction plate body 32, the large guide pull plate 31 is used to connect the main traction rope; the anti-twist device 34 is connected to the tail end of the traction plate body 32, so The anti-twist device 34 is coaxial with the large guide pull plate 31. The small guide pull plates 33 are provided on both sides of the anti-twist device 34 at the tail end of the traction plate body, and two small guide pull plates are pr...

Abstract

The invention provides a matching asymmetric traction plate and a line release pulley for construction of one-pull-three tension line release. The asymmetric traction plate comprises a large guided pulling plate, a traction plate body, small guided pulling plates and an anti-twister. Two small guided pulling plates and one small guided pulling plate are respectively arranged at both sides of the anti-twister of the tail end of the traction plate, and two leads and one lead are respectively connected with both sides. The line release pulley comprises a hanging plate, a bracket, a bearing shaft,a steel wire rope pulley and wire pulleys. Two wire pulleys and one wire pulley are respectively arranged at both sides of the steel wire rope pulley, and the position of the wire pulley, which corresponds to the steel wire rope pulley, is in one-to-one corresponding with the position of the small guided pulling plate, which corresponds to the anti-twister. The traction plate cannot overturn dueto the guarantee of the requirements on a certain distance from the small guided pulling plate to an axial line of the anti-twister as well as a lightening hole and a balancing weight which are additionally arranged on a certain position of the traction plate body. The line release pulley is hung on a transmission tower by two hanging holes of the hanging plate, asymmetric loads subjected in linerelease are transmitted to the tower through a connecting piece, thereby guaranteeing the stability of the pulley.

Description

technical field [0001] The invention belongs to the field of tension pay-off construction equipment for overhead power transmission lines, and in particular relates to an asymmetrical traction plate and a pay-off pulley for "one pull three" tension pay-off. Background technique [0002] Tension unwinding refers to the use of tractors, tension machines, pay-off blocks, traction plates and other construction equipment and tools to spread out the wires, so that the wires have a certain tension during the unwinding process, so that they are lifted off the ground and cross obstacles in the air. A setting-out construction method in which the state is laid out on each foundation tower in the setting-out section. At present, tension setting-out has become the most important construction method for the erection of overhead transmission line conductors at home and abroad. Compared with manual setting-out, it has obvious advantages such as less wear of wires, saving manpower, and impro...
