Problems solved by technology
However, under normal working conditions, the solenoid valve inside the hydraulic safety valve is in a energized state. When the operator's operating posture is incorrect, or the operator touches the operating mechanism by mistake when getting off the vehicle, it is very easy to cause an accident.
[0004] However, with the existing hydraulic safety valve, it is impossible to detect the operator's operating state in real time, which reduces the safety of construction machinery

The present application provides a safety protection system and method for construction machinery, which relate to the technical field of construction machinery. The system includes: multiple sets of sensors, controllers, control valves, hydraulic safety valves and operating mechanisms; the control valves, hydraulic safety valves and operating mechanisms are connected in sequence through oil circuits; the controller is electrically connected to the pilot solenoid valve in the hydraulic safety valve to Detect whether the pilot solenoid valve is energized; multiple sets of sensors are respectively installed in different positions in the operating room of the construction machinery; the controller is electrically connected to multiple sets of sensors to detect multiple sets of operation data obtained from multiple sets of sensors when the pilot solenoid valve is powered on; The controller is also electrically connected with the control valve to judge whether the safe operation condition is satisfied according to multiple sets of operation data, and if not, the control valve is closed to prevent the hydraulic oil from supplying oil to the operating mechanism. In the solution of the present application, the operating state of the driver can be detected, so that the safety protection of the construction machinery in the working state is realized, and the safety of the construction machinery is improved.
Description
technical field [0001] The invention relates to the technical field of construction machinery, in particular to a safety protection system and method for construction machinery. Background technique [0002] With the development of society and the needs of construction, the scope of use of construction machinery is becoming wider and wider. For example, excavators, bulldozers and loaders play a pivotal role in mineral development, water conservancy construction and road construction. During the construction process, accidents are easily caused due to irregular operation of the driver or accidental contact with the operating mechanism when the solenoid valve inside the hydraulic safety valve is energized. [0003] At present, when construction machinery is not working, the solenoid valve inside the hydraulic safety valve is not energized, which can prevent the driver from accidentally touching the operating handle when getting on and off the vehicle, and avoid safety acciden...
