Description

Technical Field

[0001] The utility model relates to a device capable of stably supporting and protecting a roller table radiating grating, and belongs to the technical field of signal detection equipment for a bar production line. Background Art

[0002] The beam grating is used to detect rebar at the double flat drag of the bar production line. When the rebar passes through the double flat drag roller and reaches the beam grating, the beam grating loses the signal. When the rebar completely passes through the beam grating, the beam grating gets the signal again, and the double flat drag moves the rebar to the inspection table. The existing beam grating transmitter and receiver are distributed on both sides of the double flat drag roller. The beam grating transmitter and receiver are installed on the bracket respectively. Due to the large vibration during the operation of the roller, the beam gratings independently installed on the bracket will shake irregularly when the roller vibrates during operation, making the beam grating unable to work stably. The signal of the beam grating receiver is intermittent, causing the double flat drag to often malfunction. At the same time, the existing beam grating is installed on the bracket without external protection and is easily damaged by external impact, which seriously affects the production of bars.
