Problems solved by technology

[0002] The traditional regular inspection method of cranes installs sensors on site, measures for a period of time according to the detection rules and procedures, and obtains part of the sample data to judge the reliability of the equipment. It cannot understand the actual operation of the crane in real time. operating conditions, this detection method is increasingly unable to meet people's requirements

Embodiment Construction

[0025] The holographic detection method of the portal crane is mainly divided into two aspects: quantitative detection and qualitative detection. The quantitative detection items include the detection of lifting weight, the detection of the amplitude, the detection of the safety distance of the same or different track running mechanism, the detection of working time, and the temperature of lubricating oil. Detection, wind speed detection, environmental factor detection; qualitative detection items include lifting / lowering limit detection, lifting brake safety limit detection, rotation angle limit detection, power supply cable reel safety limit detection.

[0026] Such as Figure 4 As shown, the measurement of the lifting weight is the measurement of the tension of the rope. Install an absolute encoder at the shaft end of the drum of the crane lifting mechanism, detect the absolute angle of the drum through the absolute encoder, measure the length of the wire rope, and transmit...

Abstract

The invention provides a portal crane holographic detection method and a safety monitoring platform. The holographic detection method is divided into a quantitative detection project and a qualitative detection project. The safety monitoring platform comprises a remote terminal 1, internet 2, a gateway 3, a field industrial Ethernet 4 and a plurality of field sensing networks 5, wherein each field sensing network 5 comprises a field instrument 6 and a sensor set 7. The holographic detection method can be used for carrying out comprehensive online monitoring detection on a crane so that the labor intensity of detectors is greatly alleviated, manpower is saved and the working efficiency is improved. The current operation situation of mechanical equipment can be known in real time by equipment using and managing workers; meanwhile, remote real-time monitoring can be carried out; and the problems can be conveniently found in time and corresponding measures are adopted, and accidents are avoided. Manufacturers of equipment can know about the problems in an equipment operation process in time and theoretical foundations are provided for the improvement of the equipment.

Description

technical field [0001] The invention relates to the field of crane safety monitoring, in particular to a holographic detection method for a portal crane. Background technique [0002] The traditional regular inspection method of cranes installs sensors on site, measures for a period of time according to the detection rules and procedures, and obtains part of the sample data to judge the reliability of the equipment. It cannot understand the actual operation of the crane in real time. This detection method cannot meet people's requirements increasingly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a holographic detection method for a portal crane. [0004] In order to solve the above technical problems, the present invention provides a holographic detection method for a portal crane. The holographic detection method is mainly divided into two aspects: quantitative detection and qualitative detection. Quantita...
