Power transmission and distribution line concrete pole steel strand manufacturing platform

Abstract

The invention discloses a power transmission and distribution line concrete pole steel strand manufacturing platform comprising an upper cross beam and a lower cross beam which are arranged in parallel. A connecting plate is vertically arranged between the upper cross beam and the lower cross beam; the upper beam is provided with a wedge-shaped clip fixing device and a steel strand back binding fixing device; and the joint of the connecting plate and the lower cross beam is provided with a radian grab bend fixing device. The invention can strictly control the dimensions, the bent radians and the connection tightness of all parts in the concrete pole steel strand manufacturing process, and can completely meet the quality standard specified in DL / T 741-2001 Overhead Transmission Line Operation Rules. The invention mainly satisfies the demands of the quality standard and the technical standard in the concrete pole steel strand manufacturing process, reduces the labor strength of operation staff and the number of the operation staff to the minimum, can be operated by one person only and has strict quality standard control on dimension scales, steel strand bent radians, the connection tightness of all parts, a binding process, a compression joint process and the like in steel strand manufacture.

Description

technical field [0001] The invention belongs to the technical field of power system transmission and distribution line construction, and in particular relates to a production platform for concrete pole steel strands of power transmission and distribution lines. Background technique [0002] The steel strand of the concrete pole is widely used in the transmission and distribution lines of the power system. It is an important part of the transmission and distribution line. Tilting, toppling, and even more serious accidents such as broken poles and broken wires, seriously affect the normal operation of the power system. [0003] In the existing construction work, the production of steel strands for concrete poles needs to be carried out on the construction site by two or more persons; the labor intensity is high, the efficiency is low, and the unqualified rate of the process quality of steel strand production is high, so it is difficult to achieve " The quality standard of Ove...

AI Technical Summary

Problems solved by technology

[0002] The steel strand of the concrete pole is widely used in the transmission and distribution lines of the power system. It is an important part of the transmission and distribution line. Tilting, toppling, and even more severe accidents such as downed poles and broken wires, seriously affect the normal operation of the power system

[0003] In the existing construction work, the production of steel strands for concrete poles needs to be carried out on the construction site by two or more persons; the labor intensity is high, the efficiency is low, and the unqualified rate of the process quality of steel strand production is high, so it is difficult to achieve " Quality Standards of Operation Regulations for Overhead Lines

After most of the steel strands of concrete poles are manufactured, there is a large gap between the tongue plate of the wedge-shaped clamp of the steel strands and the steel strands (the gap width is 3-5 mm); Under the action of balance tension or natural external force, the steel strand will be loosened and the concrete pole will be inclined.

At present, the market and domestic power equipment manufacturers have not yet appeared or produced a device that can use special equipment to make concrete rod steel strands
