A tension-resistant drainage lap ladder

Abstract

A tension drainage overlap joint ladder relates to the power transmission line maintenance tool technology field. The ladder comprises a pole and tower fixing lock regulator (6), an elevating side ladder (7), an X-type safety stay wire (8) and a manned transverse ladder (12). The ladder has advantages that the structure is simple; installation and maintenance are convenient; work efficiency is high; work intensity is small; a drainage wire is in a natural pendulous circular arc shape after being installed, is not distorted and has no hard bending portions and other defects; a pressing plate of a drainage end is connected to a bolt in a tightening-moderate mode; and a technology is good and maintenance cost is reduced.

Description

1. Technical field [0001] The invention relates to the technical field of maintenance tools for power transmission lines, in particular to a tension-resistant drainage lap ladder. 2. Background technology [0002] With the rapid development of the economy and society, the number of electricity customers continues to increase, and the load of transmission lines has increased significantly, making the line run at full load or overload. At the same time, when the construction process of the drainage part is not in place or there are remaining defects, the drainage line and the parallel ditch line will also generate heat and corona discharge during the construction of the line. The above conditions will eventually cause the transmission line to withstand tension. The drain line is disconnected, which affects the normal operation of the transmission line and causes a line trip accident; the traditional method of overlapping the drain line is that the operator drags the two ends o...

Problems solved by technology

[0002] With the rapid development of the economy and society, the number of electricity customers continues to increase, and the load of transmission lines has increased significantly, making the line run at full load or overload. At the same time, when the construction process of the drainage part is not in place or there are remaining defects, the drainage line and the parallel ditch line will also generate heat and corona discharge during the construction of the line. The above conditions will eventually cause the transmission line to withstand tension. The drain line is disconnected, which affects the normal operation of the transmission line and causes a line trip accident; the traditional method of overlapping the drain line is that the operator drags the two ends of the drain line to the cross-arm for connection and then puts it back under the cross-arm; but due to The limitation of the cross-arm operation not only fails to meet the safety distance between the drainage line and the cross-arm, but also brings great hidden dangers to the later operation due to poor workmanship and drainage deformation. Therefore, in order to ensure the safety and stability of the transmission line operation, During the construction period of the transmission network, it is necessary to produce drainage lines with excellent craftsmanship or promptly repair and replace broken lines for drainage, and develop a tension-resistant drainage lap ladder
