Chassis measurement positioning device and calibration method

Abstract

The invention discloses a chassis measurement positioning device and a calibration method. The chassis measurement positioning device comprises a base frame, a rotating rod, a first probe, a second probe, a measuring ring, a locking device and a probe moving device, wherein the locking device is installed on the upper part of the base frame, the first probe is fixedly connected with the locking device, the first probe and the locking device are both located in the base frame, and the rotating rod is connected with the locking device. The method comprises the steps of S1, inputting the model ofan electric pole, and obtaining the bottommost diameter length value d of the electric pole according to the model of the electric pole; S2, reading a measurement value D of the first probe; S3, obtaining a measurement value h of an electronic measurement ruler; and S4, acquiring measurement data of an electronic scale, and calculating according to a perimeter formula to obtain a measurement diameter L. Through the first probe, the second probe and the measuring ring, two kinds of measurement of the chassis burial depth of the electric pole are achieved, one pole can be reused, data can be measured and checked, and the measuring precision of the chassis burial depth of the electric pole is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to a chassis measurement and positioning device and a calibration method. Background technique [0002] In order to stabilize the pole during power line construction and prevent the pole from tilting or sinking, the chassis is generally fixed to the bottom of the pole. The chassis is actually the prefabricated concrete foundation of the pole. This kind of foundation is mostly used for concrete poles and is mainly assembled on site. At present, in the construction of poles, there are problems of missing chassis or insufficient buried depth of the chassis, and it is difficult to be found, which is easy to cause damage to the line. Construction defects such as pole tilting and pole sinking endanger the safety of the line; therefore, it is particularly necessary to develop a test device that can locate the chassis and accurately measure the buried depth of the chassi...

Problems solved by technology

[0005] The invention mainly solves the problem of poor measurement accuracy and inability to calibrate the buried depth of the chassis of the electric pole in the existing technology; it provides a chassis measurement and positioning device and a calibration method, which realizes multiplexing of one pole, and can directly measure the buried depth. The buried depth value can also be obtained by measuring the perimeter, and mutual verification is carried out, which greatly improves the measurement accuracy of the buried depth of the pole
