Intelligent monitoring system for hydraulic grab

Abstract

The invention provides an intelligent monitoring system for a hydraulic grab. The intelligent monitoring system comprises an information collection system, a site parameter monitoring system, a site display terminal system and a remote terminal system, wherein the information collection system is arranged on the grab; the site parameter monitoring system and the site display terminal system are connected with the information collection system; the remote terminal system is connected with the site display terminal system. The intelligent monitoring system can be used for comprehensively detecting the working condition of each system of the hydraulic grab and sending the data to a site display terminal and a remote terminal via a wired / wireless data chain during a working process of the hydraulic grab. Therefore, when the hydraulic grab is in work, the data of each part of a hydraulic system can be acquired and displayed in real time; when monitoring items are over the limit because of abnormity of the system, the system is capable of automatically giving an alarm to remind an operator; meanwhile, according to the system, only a plurality of brackets need to be arranged for mounting a sensor and a site monitoring system, so the system causes small changes of the original structure of the hydraulic grab and is beneficial for batched upgrading and reconstruction.

Description

technical field [0001] The invention relates to a hydraulic grab, in particular to an intelligent monitoring system for a hydraulic grab. Background technique [0002] The hydraulic grab is a grabbing spreader that uses a hydraulic system to control the opening and closing of the grab to complete the work. A typical hydraulic grab is mainly composed of a grab body, a hydraulic grab motor, and a hydraulic grab hydraulic assembly. Compared with the traditional mechanical grab, the hydraulic grab has high working efficiency and can be used without large-scale modification of the crane. The control system of the hydraulic grab is mainly completed by the electronically controlled reversing valve, so its control system can be matched with automation. control system, resulting in better system expansion. [0003] However, since the grab is a remote-controlled grab spreader, the distance between the grab and the operator is tens of meters or even tens of meters in some working env...

AI Technical Summary

Problems solved by technology

Therefore, when the traditional hydraulic grab is working, it is impossible to monitor the working status of the grab

Once the grab breaks down during the working process, it will easily cause the hydraulic grab to grab weakly, the grab speed will drop, or even accidentally loosen when the grab is closed, or the motor will be burned due to overload, causing serious accidents.
