Bridge crane wheel group operation safety detecting method

Abstract

The invention discloses a bridge crane wheel group operation safety detecting method, which comprises the following steps that when a bridge crane operates, the wheel axial displacement distance is detected by an inductance approach switch; when the axial displacement distance of the wheel exceeds the set displacement allowable deviation, a warning indicating lamp is on; a warning loudspeaker gives an alarm; when the bridge crane operates, the wheel group operation noise value is detected by a free field measuring microphone; when the noise value is increased and exceeds the set allowable deviation, the warning indicating lamp is on; the warning loudspeaker gives an alarm; when the bridge crane operates, the wheel group operation temperature is detected by an infrared thermometer; when thetemperature raise caused by serious friction of each component in the wheel group occurs or the temperature exceeds the set operation temperature allowable deviation, the warning indicating lamp is on; the warning loudspeaker gives an alarm. The crane operation during the work is monitored in real time; the equipment operation efficiency is improved; the potential safety hazard of the bridge crane is reduced.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a method for detecting the running safety of a wheel set of a bridge crane. Background technique [0002] Bridge crane is a kind of bridge type crane whose bridge frame runs on elevated track, also known as overhead crane. The bridge frame of the bridge crane runs longitudinally along the rails laid on the elevated sides on both sides, and the hoisting trolley runs horizontally along the rails laid on the bridge frame, forming a rectangular working range, which can make full use of the space under the bridge frame for hoisting and transporting materials. Hindered by ground equipment. This kind of crane is an important tool and equipment to realize the mechanization and automation of the production process in modern industrial production and lifting transportation. have been widely used. [0003] Among them, due to the frequent operation of the active wheel group of ...

AI Technical Summary

Problems solved by technology

The disadvantages of this are: 1. The bridge crane stops running during the inspection, which affects the operation and use of the equipment; 2. Professionals are required to perform the inspection, and the inspection time is long, and the work efficiency of the personnel is low; 3. The inspectors carry out the inspection at high altitude. The working environment is more dangerous; 4. Existing problems can only be found during parking inspections, and cannot be monitored during operation, and there are still potential safety hazards during the inspection interval
