Description

Real-time monitoring system of gantry crane

The present invention relates to a crane monitoring system, and more particularly, to a gantry crane real-time monitoring system for providing real-time monitoring information on the operation and abnormal operation of a gantry crane installed at a container pier.

In general, a gantry crane refers to a crane installed at a pier for unloading a container loaded on a container ship from a ship or loading a container loaded in a yard onto a ship, and is also referred to as a container crane.

Gantry cranes can be classified into Quay (STS Crane; Ship To Shore Crane) and Yard cranes according to their installation location and purpose of use.

When a ship enters the pier, a container crane (quay crane) lifts and moves the container from the ship, and moves it to a container yard (CY; Ccontainer Yard) where the container is temporarily stored through a yard tractor, where the container is removed from the vehicle. The equipment that unloads and loads the container yard is called a transfer crane or yard crane.

Such a gantry crane is an indispensable main loading and unloading equipment in a port facility, and is a very large-sized equipment. When a problem occurs, it can lead to a large-scale accident as well as costly loss, so safety equipment is very important.

Therefore, the gantry crane device has an overload safety device, and the safety device is composed of a mechanical or electronic safety device.

However, such an overload device was not sufficient to ensure the safety of the gantry crane device.

Korean Patent Registration No. 1863115 proposes a “smart crane safety management system” to solve the above problems.

Such a conventional crane safety management system is intended to provide a smart crane safety management system that can efficiently manage crane devices and check safety using big data measured from multiple sensors,

A load cell, a noise sensor, a vibration sensor, a displacement sensor, and a current and voltage sensor provided at each of a plurality of locations of the crane device include hoisting load, noise, vibration, displacement, current and voltage values at each location. It configures a detection module that detects the crane safety information to be detected, receives the crane safety information sensed from the detection module in real time, provides it on the management and web page, and provides the crane safety information in the management application through the smart terminal means. so that it can be checked in

As such, the conventional smart crane safety management system can efficiently and systematically manage crane devices and check safety using big data measured from multiple sensors. In addition, since the information of various sensors can be easily and conveniently checked using a mobile phone application, the efficiency and safety of the crane can be increased.

However, in order to perform safety management by monitoring a gantry crane that is larger and provides various functions, more detailed information on crane operation is required, and the conventional smart crane safety management system is not sufficient.

There is a high frequency of failures during operation due to wear and tear.

Because the productivity of a container terminal is inevitably affected by the operation rate of stevedoring equipment in the terminal, that is, the productivity of a container terminal is affected by the failure frequency of the gantry crane, so preventive maintenance suitable for the characteristics of the gantry crane is required. .

Preventive maintenance is to maintain the system at any point in time before a system failure occurs. Since it is before a failure actually occurs, system maintenance costs will be incurred, but system idle costs and opportunity loss costs due to failures can be prevented. In recent years, the need for preventive maintenance has increased.

Failure occurs when the accumulated fatigue due to long-term use of parts exceeds the endurance limit, and wear and failure can be prevented through inspection and replacement of parts before the life of parts arrives, and also stress such as vibration, pressure, and voltage of equipment Failure occurs when exceeds the strength of the part, and failure due to stress can be prevented in advance by preventing excessive stress through monitoring and risk detection.
