Title:
WOBBLER MECHANISM AND CONCRETE PUMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/035903
Kind Code:
A1
Abstract:
A wobbler mechanism is used for driving a distributing valve of a concrete pumping device to wobble, and comprises a wobbling arm (6) for driving the distributing valve, and two hydraulic oil cylinders (2, 4) for driving the wobbling arm (6) to wobble from side to side. One end of each of the two hydraulic oil cylinders (2, 4) is connected to left and right sides of the wobbling arm (6), and the hydraulic oil cylinders (2, 4) are two-stage hydraulic oil cylinders (2, 4). Also disclosed is a concrete pumping device having the wobbling mechanism. The wobbling mechanism and the concrete pumping device having the wobbling mechanism is fast in direction change and has a low impact, so that the direction change time of the wobbling mechanism is close to that of a master cylinder of the concrete pumping device, thereby greatly improving pumping continuity.
