Title:
CANTILEVER SUPPORT AND WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/021300
Kind Code:
A1
Abstract:
A cantilever support and a work machine. The cantilever support comprises a telescopic cantilever (100), a first valve set (102) and an emergency pipeline (201), wherein the telescopic cantilever (100) comprises an inner cavity (101); the first valve set (102) is configured to be connected to an executing element of a spreading cantilever section set (130); the emergency pipeline (201) is arranged in the inner cavity (101), and one end of the emergency pipeline (201) is connected to the first valve set (102), and the other end of the emergency pipeline (201) is suspended. In order to overcome the defect that in the prior art, under the extreme condition of no electricity, the cantilever support cannot be withdrawn, according to the cantilever support, an emergency pipeline (201) is connected to a first valve set (102), the emergency pipeline (201) is arranged in an inner cavity (101) of a telescopic cantilever (100), and under the extreme state of no electricity, etc., the emergency pipeline (201) is connected to an emergency hydraulic system, so that a spreading cantilever section set is withdrawn, and the reliability of emergency withdrawing of a cantilever support is improved.
