Abstract

The present invention relates to an unreeling barrel for a power transmission stranded cable. The present invention has the technical scheme that the power transmission stranded cable which has interlayer relaxation caused by bend is tightly pressed again. The present invention has the technical characteristics that a conical pipe is connected with a rotating shaft of the unreeling barrel through two connecting rods; the power transmission stranded cable is output in the conical pipe at the time of cable unreeling. The present invention has the goal of eliminating the interlayer relaxation of the power transmission stranded cable caused by the bend. The conical pipe is connected with the rotating shaft of the unreeling barrel through the connecting rods, the power transmission stranded cable is output from the conical pipe, and the conical pipe tightly presses the power transmission stranded cable with the interlayer relaxation again, so the present invention reaches the goal.

Description

防止输电绞线松弛的放线筒 Pay-off barrel to prevent the slack of the transmission twisted wire

所属技术领域Technical field

本发明涉及一种输电绞线的放线装置，尤其是放线筒。The invention relates to a pay-off device for a power transmission stranded wire, in particular to a pay-off cylinder.

背景技术Background technique

目前，公知的放线筒是轳筒。放线前，输电绞线绕在放线筒上，张力机牵引输电绞线，输电绞线带动放线筒转动，实现放线筒的放线功能。由于放线筒使输电绞线弯曲，引起输电绞线的层间松弛，导致输电绞线的内摩擦增大，从而加速输电绞线在运行时由微风振动引起的疲劳断股。At present, the known pay-off drum is the drum. Before paying off, the power transmission stranded wire is wound on the pay-off barrel, the tension machine pulls the power transmission stranded wire, and the power transmission stranded wire drives the pay-off barrel to rotate, realizing the pay-off function of the pay-off barrel. Because the pay-off barrel bends the transmission strand, it causes the interlayer relaxation of the transmission strand, which leads to the increase of the internal friction of the transmission strand, thereby accelerating the fatigue strand breakage of the transmission strand caused by breeze vibration during operation.

发明内容Contents of the invention

为了克服现有的放线筒使输电绞线弯曲，引起输电绞线的层间松弛的不足，本发明提供一种放线筒，它能将出现层间松弛的输电绞线重新压紧。In order to overcome the deficiency that the existing pay-off barrel bends the transmission strand and causes interlayer relaxation of the transmission strand, the present invention provides a pay-off barrel, which can re-compress the transmission strand with interlayer relaxation.

本发明解决其技术问题所采用的技术方案是：通过联杆将一锥形管与放线筒的转轴相联，输电绞线从锥形管中输出，锥形管将出现层间松弛的输电绞线重新压紧。The technical solution adopted by the present invention to solve the technical problem is: a conical pipe is connected to the rotating shaft of the pay-off cylinder through a connecting rod, and the stranded power transmission wire is output from the conical pipe, and the conical pipe will have interlayer slack power transmission. The strands are re-tightened.

本发明的有益效果是：消除放线时输电绞线的层间松弛，从而使其内摩擦系数不在放线过程中增大，延长其使用寿命。The invention has the beneficial effects of eliminating interlayer slack of the transmission stranded wire during wire unwinding, so that the internal friction coefficient does not increase during the wire unwinding process and prolongs its service life.

具体实施方式Detailed ways

联杆(2)、(3)的一端与放线筒(1)的转轴相联，另一端与锥形管(4)相联，输电绞线从锥形管(4)中输出。锥形管(4)的材质坚韧，内壁光滑，出口半径等于输电绞线的产品半径，以使输电绞线在通过锥形管(4)后，其半径等于输电绞线的产品半径。One end of the connecting rod (2), (3) is connected with the rotating shaft of the pay-off barrel (1), and the other end is connected with the tapered pipe (4), and the power transmission stranded wire is output from the tapered pipe (4). The material of the tapered pipe (4) is tough, the inner wall is smooth, and the outlet radius is equal to the product radius of the power transmission stranded wire, so that after the power transmission stranded wire passes through the tapered pipe (4), its radius is equal to the product radius of the power transmission stranded wire.

Claims (1)

1.一种输电绞线放线筒，其特征在于一锥形管通过两根联杆和放线筒转轴相联，锥形管的出口半径等于输电绞线的产品半径，放线时，输电绞线从锥形管中输出。1. A power transmission twisted wire pay-off barrel, characterized in that a tapered tube is connected with the shaft of the pay-off barrel through two connecting rods, the outlet radius of the tapered tube is equal to the product radius of the power transmission twisted wire, when the wire is unwound, the power transmission Stranded wire exits the tapered tube.
