WIPO Patent Application WO/2022/105239
Kind Code:
A1
Abstract:
A work machine, comprising a truck body (1), a turntable (2), a boom (5), and an amplitude change mechanism (6). A slewing assembly (3) located behind a driving cab (4) is mounted on the truck body (1); the turntable (2) is mounted on the slewing assembly (3); the turntable (2) comprises a hinge arm (23); the hinge arm (23) can slew and be positioned above the driving cab (4) with respect to a slewing axis of the turntable (2); a first hinge structure (231) and a second hinge structure (232) are provided on the hinge arm (23); the eccentric distance of the first hinge structure (231) and/or the second hinge structure (232) with respect to the slewing axis of the turntable (2) is greater than the distance between the rear end of the driving cab (4) and the slewing axis; the first hinge structure (231) is hinged to one end portion of the boom (5), the second hinge structure (232) is hinged to one end of the amplitude change mechanism (6), and the other end of the amplitude change mechanism (6) is hinged to the middle of the boom (5). According to the work machine, the boom can slew and be positioned above the driving cab along with the hinge arm, thereby effectively making use of the spare space above the driving cab, greatly increasing the arrangement length of the boom, effectively reducing the overturning moment of the boom, and improving the work capability of the boom.
