ANTI-FALLING ASSEMBLY AND LIFTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/067195
Kind Code:
A1
Abstract:
An anti-falling assembly and a lifting device. The anti-falling assembly (100) comprises a sliding plate (110), a connector (120), an assistance mechanism (130), and a locking mechanism (140). The sliding plate (110) is in limiting connection with a stand column (200) in a first direction; the connector (120) abuts against the sliding plate (110), and is used for connection to a lifting rope (300), so that the lifting rope (300) can drive the sliding plate (110) to ascend and descend in a second direction by means of the connector (120); the assistance mechanism (130) is arranged between the connector (120) and the sliding plate (110), and the assistance mechanism (130) is used for driving the connector (120) to descend relative to the sliding plate (110) in the second direction when the lifting rope (300) fails; and the locking mechanism (140) is arranged on the sliding plate (110) and comprises a transmission structure (141) and a locking block (142), wherein the transmission structure (141) is used for being driven by the connector (120) to drive the locking block (142) to move toward the stand column (200) when the connector (120) descends relative to the sliding plate (110) in the second direction, so that the locking block (142) abuts against a surface of the stand column (200), and the sliding plate (110) stops descending. When the lifting rope (300) fails, the sliding plate (110) can stop falling and be fixed to the stand column (200), so as to avoid safety accidents.
