Abstract

The invention aims to provide an automatic detection device of a vibrating screen square girder. The device comprises brackets, axial movement systems and circumferential direction rotation systems, wherein each axial movement system of the device consists of a driving travelling mechanism and a driven travelling mechanism; each driving travelling mechanism comprises a motor, a motor base, a speed reducer, a driving wheel, a initiative wheel bracket, a spring I and a nut I; each driven travelling mechanism comprises a driven wheel, a driven wheel bracket, a spring II and a nut II; each circumferential direction rotation system comprises a connecting plate, a track, a sensor base, a tension spring, an adjusting nut and a sensor box. The traditional manual detection is low in efficiency and difficult in detection at various places, while the device provided by the invention can realize the automatic detection and simplify the detection, remarkably improves the detecting efficiency, is high in automation degree and excellent in movement stability, effectively eliminates the influences of shaking and speed on detection signals, and improves the repeatability and accuracy of detection signals to a great extent.

Description

technical field [0001] The invention relates to a detection device for a square girder, and relates to the field of automatic detection devices. In particular, it relates to an automatic detection device for a square girder of a vibrating screen. Background technique [0002] Mining vibrating screens are used for grading raw coal, medium recovery, dehydration and removal of waste, etc. The vibrating screen is one of the key and valuable equipment in coal preparation production, and its safe operation is directly related to the safety of coal mine production. The beam of the vibrating screen bears the gravity and impact force of the screened material for a long time, and is also subjected to the action of alternating exciting force. The fracture of the beam of the vibrating screen is one of the frequent failures in actual production. [0003] The girder is the core component of the vibrating screen. It bears the gravity and static force of the structure and equipment for a ...
