Abstract：The top beam of the hydraulic support is the main bearing part of the support.In the type in-spection of the hydraulic support,whether the deformation of the top beam exceeds the standard is one of the main technical indicators to determine whether the product is qualified.It is necessary to measure the deformation of the top beam in order to verify the structural strength of the top beam when the hydraulic support is tested.In order to solve the problems of low efficiency and low repeat-ability in manual measurement of the deformation of the top beam of hydraulic support,this paper proposes a new method of deformation detection of the top beam of hydraulic support based on three-dimensional laser scanning technology,introduces the technical design scheme,analysis of results and verification of measurement results,and realizes the detection of the deformation of the top beam of hydraulic support with high accuracy and wide adaptability.The highest detection accuracy is 0.02 mm/m,which can meet the requirements of hydraulic support inspection,and also provide data support for hydraulic support inspection and design.
