CONCRETE PUMPING DEVICE, AND TRAVEL CONTROL APPARATUS AND METHOD FOR SERIES OIL CYLINDER

摘要

A concrete pumping device, and a travel control apparatus and method for a series oil cylinder. The travel control apparatus for a series oil cylinder comprises: a first position detection unit (30) mounted on a first oil cylinder (10) and used for detecting a first motion position (X) of a piston (12) in real time and generating a first motion position signal; a second position detection unit (40) mounted on a second oil cylinder (20) and used for detecting a second motion position (Y) of a piston (22) in real time and generating a second motion position signal; and a controller (50) connected to the first position detection unit (30) and the second position detection unit (40), the controller (50) receiving the first motion position signal and the second motion position signal, and controlling a volume of a communicating cavity according to a predetermined control policy, so as to control a travel of the series oil cylinder. According to the travel control apparatus, the travel of the oil cylinder can be adjusted in time.
