Anti-fall device

Abstract

The invention discloses an anti-fall device, which comprises an anti-fall hook, wherein the upper end of the anti-fall hook is a hinged end, and the lower end of the anti-fall hook is provided with a hook-shaped part; the top of the hook-shaped part is provided with an anti-fall supporting surface, and the bottom of the hook-shaped part is provided with a lower guide inclined plane; a ratchet is arranged on the anti-fall hook and is provided with a plurality of ratchet teeth; when the ratchet teeth rotate to a position above the anti-fall supporting surface along with the ratchet, the end parts of the ratchet teeth point to the tip of the hook-shaped part; an upper guide inclined plane which inclines towards a direction opposite to the upper guide inclined plane is formed on the upper side of the ratchet teeth; and the ratchet teeth are at least locked at a position where the upper guide inclined plane is formed and are prevented from rotating towards the anti-fall supporting surface. Compared with the prior art, the anti-fall device has a simple and compact structure, fulfills the aim of preventing a vehicle carrying plate from falling off without additional control, is safe and reliable, is convenient to use, and can be widely applied to various types of parking equipment.

Description

technical field [0001] The invention relates to an anti-falling device, in particular to an anti-falling device which is applied in a lift and traverse parking equipment to prevent a vehicle-carrying plate from falling. Background technique [0002] With the increasing popularity of cars, the urban space is becoming more and more narrow, especially in areas where office buildings, commercial buildings and residential buildings are densely packed, parking spaces are very tight. The multi-storey lifting and traversing parking equipment solves this problem very well. At present, the general-purpose multi-storey lifting and traversing parking equipment is generally equipped with a fall prevention device, which is used to prevent the vehicle from falling due to the breakage of the chain or wire rope of the vehicle-carrying plate when the vehicle is in a stationary state. However, these anti-falling devices generally have the disadvantages of complex structure and inconvenient co...
