The invention discloses an automatic detection and control device and method for controlling an electric handle of a stand column. The automatic detection and control device comprises the electric handle, an PLC, an alarm unit, a display unit and a proportional electromagnetic group valve, wherein the electric handle, the alarm unit, the display unit and the proportional electromagnetic group valve are all connected with the PLC, the proportional electromagnetic group valve is connected with an oil cylinder on the stand column, and the PLC is connected with a tilt sensor on the stand column. According to the method, the work condition of the electric handle can be monitored in real time through the PLC, the short circuit protection and the disconnection protection are enhanced for the electric handle, and fault causes can be provided for a manipulator on a display screen. Meanwhile, the manipulator can more regularly and safely operate the electric handle under the condition that no expenses are increased.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an automatic detection and control device and method for an electric handle used to control a column. Background technique [0002] In the control of large-scale piling equipment, the control of the column is undoubtedly one of the key points of the machine motion control. The electric handle is an electronic device that controls the movement of the column. [0003] Because the working environment of piling equipment is very harsh, rain, dust, pollution of hydraulic oil, aging of electrical lines and severe vibration of machines will affect the normal operation of electronic equipment and even cause it to fail. When the electric handle fails, the mast or column will not work according to the wishes of the operator. Regardless of whether the electric handle is open or short circuited, the column will move abnormally, thus causing the machine to overturn. [0004] A...
