Potential load mechanism braking torque detecting system for harbor machine

Abstract

The invention provides a potential load mechanism braking torque detecting system for a harbor machine. The potential load mechanism braking torque detecting system comprises a testing operation terminal and a host PLC control system. The testing operation terminal comprises a remote substation interface module, a DI/DO module and an operation panel. The operation panel comprises an HMI for designating parameters and a testing result set by a brake, a key switch for selecting the testing mode, a mechanism selecting switch for selecting a tested single mechanism, a band lamp operation button for activating testing, a preparation condition indicating lamp, a testing succeeding indicating lamp and a testing failing indicating lamp. The testing operation terminal transmits operation instructions and parameter setting to the host PLC control system in the manner of Ethernet. According to the technology, a brake torque detecting control console is arranged near a tested brake, a maintainer can detect the braking torque of the brake through one key by means of a PLC, a frequency converter, a motor and other devices of the on-machine control system, the system automatically judges the detecting result, and archival storage is achieved.

Description

technical field [0001] The invention relates to the technical field of port machinery, in particular to a detection system for braking torque of a potential load mechanism for port machinery. Background technique [0002] Whether the braking torque of potential energy load mechanisms such as lifting and pitching of port machinery meets the design requirements directly affects the production and operation safety of the equipment. At present, in elevators, automobiles and other fields, the brake torque can be monitored by installing pressure detection sensors on the brake discs. However, due to the differences in the mechanical structure of the equipment, the use environment, and the type of load, the relevant detection devices are not practical in port machinery. application. The maintenance personnel of port machinery generally detect the braking torque by measuring the gap between the brake disc and the brake pad. Whether the braking torque meets the safety production requ...

AI Technical Summary

Problems solved by technology

The maintenance personnel of port machinery generally detect the braking torque by measuring the gap between the brake disc and the brake pad. Whether the braking torque meets the safety production requirements cannot be accurately judged. If the port machinery fails to brake during work, Major safety accidents such as load falling or equipment overturning are very likely to occur, posing a great threat to personal and property safety
