Description

A remote monitoring system for the spreader of jib type portal crane

technical field

The utility model relates to the technical field of remote monitoring, in particular to a remote monitoring system used for the spreader of a jib type portal crane in a shipyard.

Background technique

At present, the operation of portal cranes in shipyards generally relies on the driver to observe the hook in the cab for lifting operations. If the hook is blocked by objects in the cabin or the hull structure, a blind area of sight will be formed. It is necessary to rely on the command of the lifter to carry out the operation. The hoist is not only responsible for hooking and unloading the hook, but also directs the driver to lift the hoist through whistle, walkie-talkie, gestures and other means. At this time, the driver is almost ignorant of the load situation under the hook and the surrounding environment, which brings danger to the hull, the hoisted objects and the personnel who direct the driver to lift.

With the increasing range and lifting load of the crane, the outfitting environment is becoming more and more complex, and the work intensity and difficulty of the driver and the hoist are increasing. Now some super large gantry trolleys are equipped with camera devices. It can help the driver to effectively monitor the lifting points and loads, improve the work efficiency of crane outfitting and avoid hidden dangers of accidents. However, the environment of the production site is complex, and the line of sight of the lifting worker is often blocked by other structures, and it is impossible to observe the complete lifting trajectory. In order to make up for the limitations, sometimes it is necessary to rely on judgment. Due to the narrow hatches of some ship types and insufficient lighting in the area, during the descent, the crane worker cannot judge the situation in the cabin, and sometimes needs to rely on experience to make judgments, and the outfitting has a certain degree of blindness. Although the driver is condescending, with the increase of the range, due to the sight and structural obstruction, it is easy to misjudge the environment of the lifting point, causing hidden dangers in production. In addition, there are many hoisting equipment on the job site, especially the hoisting equipment controlled by frequency conversion, the serial frequency of the signal and the power frequency signals generated by other equipment interfere seriously with each other. The use of optical fiber cables for video signal transmission solves the problem of interference, but the failure rate of video cable breakage due to boom amplitude change is relatively high.

The probe monitoring in the prior art is complicated to operate, and the position of the camera needs to be adjusted frequently to find the monitoring point. Due to the frequent adjustment of the camera monitoring point, the production operation frequency of the crane driver is affected, so that the operator will operate the video monitoring system for a while, and at the same time Knowing how to operate a crane is prone to operational errors, and the monitoring probe vibrates with the operation of the mechanism, causing the camera to shake, making the display screen blurred and affecting safe operation.
