Embodiment Construction
[0019] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0020] As shown in the accompanying drawing 1, a measurement and control system for identifying the working state of a hydraulic rock drill according to the present invention includes a power mechanism, an actuator, an overflow valve, a rock drilling control valve group, and a measurement and control system; wherein:
[0021] The power mechanism includes two one-way pumps B1 and B2. The one-way pump B1 is driven by a motor M1 equipped with a frequency converter T. Adjust the frequency converter T to change the speed of the motor M1, thereby changing the displacement of the pump B1 to change the speed of the load. The identification result of the working state of the measurement and control system makes R feedback to control the frequency converter T; the one-way pump B2 is driven by the motor M2 to provide the required pressure oil.
[0022] The executive ...
