Description

The disclosure relates to the field of machinery, and in particular to a method for automatically controlling the development of partially forward and partially reverse stroke, based on the transformation of hydraulic measurements, and to an automatic control system for the development of partially forward and partially reverse stroke, based on the transformation of hydraulic measurements.

State of the art

The corresponding digging and excavating mining machine is capable of fast mining and digging using the reciprocating impact mining and digging mode and/or using the telescopic oil cylinder mining and digging mode, while the material mining and digging efficiency is high, but the mining head and digging head often cause stop or even damage mining generator or engine by overload due to mining and digging harder material, especially reciprocating impact digging machine and reciprocating impact excavator with high material mining speed, are capable of mining and dig hard material above F4, so the reciprocating impact digging machine and reciprocating impact excavator are the most advanced, scientific and practical equipment for mining and digging, because the reciprocating impact digging machine blunt impact and reciprocating impact excavator sometimes stop when the impact teeth hit the material wall, the mining and digging motor and the travel motor burn out due to overload; In order to solve the problem of engine combustion due to overload, the running power and reciprocating impact power of the reciprocating impact excavator and reciprocating impact digging machine are replaced with hydraulic motor drive or telescopic oil cylinder drive, but the mining head and the digging head of the hydraulic motor drive or the telescopic oil cylinder drive often presses against the wall of the material, resulting in a transient overpressure, so that the motor and the oil cylinder stop, and the motor and the oil cylinder cause deformation of the sealing member and the like due to the overpressure and high temperature , and even damaged, when the material mined and excavated by the machine contains little dust and has low power consumption, the engine and oil cylinder can still be damaged by frequent overpressure and stop, and m unnecessary damage to the hydraulic system can also be caused by restarting the engine and oil cylinder, which wastes time, labor and material resources, seriously reduces the production efficiency, and improves the energy-saving and environmental performance of the reciprocating impact digging machine and reciprocating excavator. - translational impact is seriously hampered; the cutting and cutting part of the corresponding mobile and crushing excavator for mine is capable of changing the power of the engine and allowing the cutting roller to rotate and crush the rock through the transmission mechanism; when coal and rock above F4 meet, because the rotary cutting motor has increased torque and runs under overload, the motor is often burned out, causing production to stop, and since the motor is used to drive the cutting part to rotate and cut the material, so as to protect the cutting teeth from damage, the rotation speed of the cutting wheel is reduced to a speed that does not exceed 45 rpm, and the rotation speed of the motor is about 1500 rpm, while the rotation speed is gradually reduced to a speed that does not exceed 45 rpm through the transmission mechanism ; In order to save space, the mobile and pulverizing excavator can use a rocker as a transmission mechanism to transmit power to the rotating roller, all of which leads to the rocker being huge, blocking the space for coal transportation, and reducing the efficiency of coal transportation, and since the rocker transmits power through the transmission mechanism, when the power is transmitted to the rotating roller, it must be ensured that the driving shaft of the rotating roller is parallel to the drive shaft of the rocker transmission mechanism, so it is necessary that the size of the connecting part of the rocker arm and the rotating roller is too large, the production cost increases, and the space for transporting scraper coal conveyor is blocked by the connecting part of the rocker arm and roller.
