Detection device

Abstract

The application relates to the technical field of non-standard detection, in particular to a detection device. The detection device comprises a base, a load detection assembly, a torque detection assembly and a noise detection assembly. The base has a bearing area for bearing a main rod of a steering machine. The load detection assembly is arranged on the base along a first direction, and is used for detecting the size and direction of the load borne by the main rod of the steering machine during rotation. The torque detection assembly is arranged on the base along a second direction, and is used for detecting the size and direction of the torque borne by the main rod of the steering machine during rotation. The noise detection assembly comprises a soundproof cover and a sound measuring instrument, and the bearing area and the sound measuring instrument are arranged in the soundproof cover. Through synchronous monitoring of mechanical parameters (load / torque) and acoustic parameters (noise), a comprehensive evaluation system of the running state of the main rod of the steering machine can be established, multi-dimensional data support for analyzing mechanical transmission efficiency and component wear degree is provided, and the detection efficiency is effectively improved.
