Vibrating conveyor operation detection method and detection device using the method

Abstract

The invention discloses a vibrating conveyer operation detection method and a detection device using the vibrating conveyer operation detection method. According to the vibrating conveyer operation detection method, an approach switch is arranged in an amplitude range of downward vibration of a vibrating material groove, a signal output end of the approach switch is connected with a programmable logic controller (PLC), discontinuous approach signals which are generated by periodic reciprocating motion of the vibrating material groove are transmitted to the PLC through the approach switch, abnormal work of a vibrating conveyer caused by the facts such as a broken motor belt of the vibrating conveyer, a broken bearing, a problem of a shock excitation mechanism can be detected, accumulation of sand in the vibrating conveyer and pits is avoided, and equipment faults are prevented from worsening.

Description

technical field [0001] The invention relates to the field of vibrating conveyors, in particular to a method for detecting the operation of a vibrating conveyor and a detecting device using the method. Background technique [0002] At present, the protection of the vibrating conveyor mainly includes: motor overload protection, power supply phase loss protection, etc., but if there is a problem with the driving parts of the vibrating conveyor, such as vibration caused by a broken motor belt of the vibrating machine, broken bearings, and problems with the excitation mechanism, etc. The vibrating conveyor is not working normally, and the materials in the vibrating conveyor cannot be conveyed out, but the motor is running normally, so the protection systems such as motor overload protection and power supply phase loss protection cannot detect abnormalities, so that the upstream conveying equipment cannot receive corresponding instructions and will continue to run. Conveying mater...

Problems solved by technology

[0002] At present, the protection of the vibrating conveyor mainly includes: motor overload protection, power supply phase loss protection, etc., but if there is a problem with the driving parts of the vibrating conveyor, such as vibration caused by a broken motor belt of the vibrating machine, broken bearings, and problems with the excitation mechanism, etc. The vibrating conveyor is not working normally, and the materials in the vibrating conveyor cannot be conveyed out, but the motor is running normally, so the protection systems such as motor overload protection and power supply phase loss protection cannot detect abnormalities, so that the upstream conveying equipment cannot receive corresponding instructions and will continue to run. Conveying materials, resulting in the accumulation of materials at the vibrating conveyor in a short period of time until the motor is overloaded and detected by the motor overload protection system to stop the operation of the equipment

Especially when the vibrating conveyor is installed in pits, closed spaces, etc., and is in an unattended state, this lack of detection of the actual operation of the vibrating conveyor cannot shut down the equipment in time to avoid material accumulation, which can easily cause equipment damage , so that there is a great hidden danger in production
