Portable subspan measuring device

Abstract

A portable subspan measuring device comprises a positioning frame, a traveling wheel, a measuring wheel, a counter, a control chip and a display. The positioning frame comprises an upper positioning plate and a lower positioning plate which are connected with each other, and the right side of the upper positioning plate is provided with a first horizontal positioning shaft, the traveling wheel is arranged on the first positioning shaft through a bearing, the right side of the lower positioning plate is provided with a horizontal second positioning shaft, the measuring wheel is disposed on the second positioning shaft through the bearing, the traveling wheel and the measuring wheel are corresponding to each other and are provided with a gap therebetween for accommodating the wire, and the counter is located on the lower positioning plate and used to calculate the walking distance of the measuring wheel; the control chip and the display are fixed on the upper positioning plate, and the signal output end of the counter is connected with the input interface of the control chip, and the display is connected with the output interface of the control chip. The device only needs an operator to push the traveling wheel to walk on the wire, so that the subspan measurement can be completed accurately and quickly, thereby greatly improving the subspan measurement efficiency.

Description

Technical field [0001] The invention relates to a portable secondary gear distance measuring device. Background technique [0002] The secondary pitch refers to the distance between the split conductor spacer rods. With the growing scale of the power grid and the higher and higher voltage levels, how to effectively, safely and reliably improve the transmission capacity is a major problem facing my country's power grid. At present, the transmission capacity is continuously increasing. In order to reduce corona loss and corona interference, and for the economy and reliability of transmission lines, multi-split conductors are widely used in transmission lines. Secondary pitch oscillation is a form of wire vibration unique to split wire. The problem of split conductor damage caused by the second-gear pitch oscillation has become a key issue affecting the safe operation of the power grid. The second-gear pitch is an important factor in the damage of the split conductor caused by th...
