Self-detection and safety system and method of hydraulic grab

Abstract

The invention provides a self-detection and safety system of a hydraulic grab. The self-detection and safety system of the hydraulic grab is characterized by comprising a sensor assembly arranged on the grab, a data acquisition and monitoring system connected with the sensor assembly, and a field display terminal system connected with the data acquisition and monitoring system; the data acquisition and monitoring system is used for controlling the hydraulic grab to stop; the field display terminal system is used for displaying relevant working parameters and control states and carrying out remote communication and storage of data. The invention also provides a control method of the self-detection and safety system of the hydraulic grab. The self-detection and safety system of the hydraulic grab is capable of well solving the problems of self-detection and safety monitoring of the hydraulic grab and capable of immediately and quickly finding out problems, thereby guaranteeing the safety of a grab work site.

Description

Technical field [0001] The invention relates to a hydraulic grab, in particular to a hydraulic grab self-detection and safety system and method Background technique [0002] The hydraulic grab is a grabbing spreader that can be controlled remotely. In some working environments, the grab is tens of meters or even tens of meters away from the operator. Therefore, when the traditional hydraulic grab is working, the working state of the grab cannot be monitored. When the grab fails, the fault diagnosis is still limited to manual operation in the detection link. Therefore, the detection and maintenance efficiency is low; the problem cannot be found in the early stage of the grab failure. [0003] Once the grab working process fails, it is easy to cause the hydraulic grab to be weak in grabbing, the grab speed to drop, or even the grab to accidentally loosen in the closed state or the motor to burn due to overload, causing serious accidents. Summary of the invention [0004] The techni...

Problems solved by technology

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

When the grab fails, its fault diagnosis is still limited to manual operation in the detection link

Therefore, the detection and maintenance efficiency is low; the problem cannot be found in the early stage of the grab failure

[0003] 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.
