Jib type crane operating status record and security protection system

Abstract

The invention relates to a work-state storing and safety protecting system used for a jib crane. The system comprises a lower computer, an upper computer, sensors and a data transmission module. The lower computer comprises an RF identification module, a CPU, a data collecting module, an output control module, a main-control system locking module, a keyboard, a storage, a display, an indicator and a buzzer. The lower computer is arranged in a cab. The upper computer comprises a computer, a control program module and an RF solidifying module. The upper computer is arranged in a ground-based office. The sensors are arranged on the key positions of the jib crane and the signals of these sensors are collected and calculated by the lower computer and then the upper computer communicates with the lower computer through the data transmission module, thus realizing the timely monitoring and data storing to the work state of the jib crane and carrying out safety protection by the judgement on the detection data.

Description

technical field [0001] The invention relates to jib cranes, in particular to a system for real-time recording and safety protection of the status of jib cranes and remote unified monitoring and management of jib crane groups. Background technique [0002] Crane accidents will not only cause huge economic losses, but also have adverse social impacts. At present, most of the overload safety protection devices of domestic jib cranes are mechanical moment limiters and lifting capacity limiters, which adopt a simple method of actuating the limit switch after the deformation of the steel plate under force, so there are the following problems: [0003] 1. Low control precision and poor repeatability. [0004] 2. The load and operating status of the jib crane cannot be displayed and reflected in real time, and the driver cannot control and adjust the operating status of the equipment accordingly. Due to the low reliability of this kind of mechanical protection device, once it fail...

AI Technical Summary

Problems solved by technology

[0009] In order to overcome the above-mentioned shortcomings of the prior art, the task of the present invention is to provide a working state record and safety protection system of a jib type crane, which solves the problems of low control accuracy and inability of the existing jib type crane overload safety protection device. Real-time display and reflection of the load and operating status of jib cranes, remote monitoring and unified management of a large number of jib cranes, etc.
