The invention comprises a small-size hydraulic automatic tamping
machine and an
intelligent control method, and belongs to the field of maintenance machines for railway permanent ways. The small-size hydraulic automatic tamping
machine comprises a
machine frame, a lifting platform (9), an upper Hall sensor (23), a lower Hall sensor (24), a
power battery pack (15), a magnetic component (25), a large-power
direct current motor (16), a pressurizing
oil pump (12), a multi-way reversing
solenoid valve (13), a hydraulic tightly-clamping mechanism (6), a multi-way
relay switch (14), a hydraulic lifting mechanism (17) and an intelligent operating platform (10), wherein the lifting platform (9) can move vertically along the machine frame; the upper Hall sensor (23) and the lower Hall sensor (24) are arranged on one of guide rails; the
power battery pack (15) is arranged on the lifting platform (9); the multi-way
relay switch (14) controls the multi-way reversing
solenoid valve (13); the hydraulic lifting mechanism (17) drives the lifting platform (9) to move vertically; and the intelligent operating platform (10) is arranged above a bearing beam (19). The small-size hydraulic automatic tamping machine has the characteristics and the advantages of saving energy, adopting an
intelligent control strategy and a man-machine conversation mode, reducing labor intensity of operators, enhancing
operability and embodying humanization, further improving efficiency and quality of railway maintenance operation and the like, along with low operating
noise and environmental friendliness.
