Supporting leg span measuring method and device

Abstract

The embodiment of the invention provides a supporting leg span measuring method and device, and belongs to the technical field of engineering machinery. The method comprises the steps of placing a laser range finder at a measuring point, wherein the measuring point is located at a first preset distance of a vertical oil cylinder of a first supporting leg; controlling the laser range finder to measure a first distance to a first position of a second supporting leg and a first vertical height between the laser range finder and the first position, wherein the second supporting leg is an adjacentsupporting leg of the first supporting leg; measuring a first horizontal rotation angle of the laser range finder from measuring the first distance to measuring the second distance; and calculating afirst supporting leg span between the first supporting leg and the second supporting leg according to the first distance, the first vertical height, the second distance, the second vertical height andthe first horizontal rotation angle. The supporting leg span measurement method and device can significantly improve the measurement efficiency and measurement precision of the supporting leg span.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a method and equipment for measuring the span of an outrigger. Background technique [0002] In the related art, the worker uses a tape measure to measure the span of the outrigger. During the specific measurement, two staff members hold one end of the tape measure respectively, place the tape measure close to the center of the same side of the outrigger cylinder, try to stretch the tape measure at the same height as far as possible, and read the measured value of the tape measure visually, and then the worker Personnel record measurements. This outrigger span measurement method has the following drawbacks: [0003] (1) Low measurement efficiency and waste of personnel: The measuring tape must be measured by two people, and it is necessary to squat down during the measurement process. The measured value can only be read after confirming that the tape is stretched ...

Problems solved by technology

[0003] (1) Low measurement efficiency and waste of personnel: The measuring tape must be measured by two people, and it is necessary to squat down during the measurement process. The measured value can only be read after confirming that the tape is stretched straight and placed at the same height at both ends. After the measurement is completed, the tape must be wiped clean after recycling

[0004] (2) Poor measurement accuracy: the tape measure will naturally sag due to the action of gravity during the measurement, especially if the water and oil in the debugging position stick to the surface of the tape measure, it will cause the sag to increase, resulting in large deviations in the measurement results
