A Method for Measuring the Dynamic Axis Spatial Position of the Rotary Kiln Supporting Wheel Group

Abstract

The invention discloses a method for measuring the dynamic axis space position of a rotary kiln supporting wheel set, relating to a method for measuring the axis space position during rotation. Its purpose is to provide a measuring method capable of high-efficiency and high-precision measurement of axes of a plurality of support wheel sets, and with high use safety. The measuring method of the present invention comprises the following steps: arranging a target base on the base of the support roller, on which a prism target ball is installed; using a total station to measure the central coordinates of the prism target ball; replacing the prism target ball with a visual measurement target ball , lay out visual measurement points on the protective shell; use monocular visual measurement equipment to measure the coordinates of the visual measurement point and the visual measurement target ball; arrange a dynamic measurement point on the rotating shaft of the supporting wheel; start the binocular visual measurement equipment to measure dynamic The coordinates of the rotation position of the measuring point, take the coordinates of all dynamic measuring points and fit the circle with the least square method, and the normal line of the center of the circle is the axis of the supporting wheel; repeat the above process to obtain the spatial position of the axis of the entire supporting wheel group.

Description

technical field [0001] The invention relates to the technical field of spatial position measurement methods, in particular to a method for measuring the spatial position of a dynamic axis of a rotary kiln supporting wheel set. Background technique [0002] As the key core production equipment in the cement firing process, the rotary kiln is generally supported by a supporting wheel set composed of more than three sets of supporting wheels. During the cement production process, the supporting wheel set supports the rotary kiln to continue rolling work. In the long-term uninterrupted operation, due to the long-term heat deformation of the supporting roller group, the wear and tear of the rolling and the subsidence of the foundation, etc., the rotation axes of the supporting roller group are twisted and uneven, resulting in greater resistance during the rolling process of the rotary kiln and increased production. The energy consumption in the furnace may even cause the rotary k...

Problems solved by technology

[0006] 3) High measurement accuracy requirements:

[0009] 1) There are certain uncertainties and human errors in the axis of manual positioning;

[0010] 2) The optical prism can only be placed on the shaft at the end of the supporting wheel, and the protective shell at the end of the supporting wheel needs to be opened during installation. Due to the high temperature environment and high-speed operation of the equipment, there is a certain degree of danger in actual operation
