Detailed Description

The technical solution of the present invention will be described in detail below with reference to specific examples.

As shown in fig. 1-3, fig. 1 is a schematic structural view of a high-safety lifting scaffold according to the present invention; fig. 2 is a schematic structural diagram of the high-safety lifting scaffold when the lifting frame brakes the lifting frame; fig. 3 is a schematic structural diagram of the anti-falling assembly in the high-safety lifting scaffold.

Referring to fig. 1 to 2, the present invention provides a high safety lifting scaffold, including: an adhere to frame 1, can install crane 2 on adhering to frame 1, be used for driving crane 2 up-and-down motion's actuating mechanism and prevent weighing down subassembly 3 for fixed mounting on wall or its building, up-and-down sliding, wherein: the lifting frame 2 is provided with a plurality of cross rods 4 which are arranged at equal intervals along the height direction, and a baffle 5 is arranged on the attachment frame 1 and on one side of each cross rod 4 in the arrangement direction.

The anti-falling assembly 3 comprises a rotating shaft 31 and a swinging block 32 which is arranged on the rotating shaft 31 in a swinging manner, one end of the swinging block 32 is positioned below the baffle 5, and the other end of the swinging block is provided with a V-shaped bayonet a with an opening facing the cross rod 4; the upper side edge and the lower side edge of the V-shaped bayonet a are arranged up and down, the upper side edge of the V-shaped bayonet a is longer than the lower side edge of the V-shaped bayonet a, when the swinging block 32 is abutted to the baffle 5, the swinging block 32 is in a horizontal state, the upper side edge of the swinging block 32 is located on one side of the moving track of the cross rod 4, and the lower side edge of the swinging block 32 is located on one side of the moving track of the cross rod 4. The rotating shaft 31 is positioned between the baffle 5 and the cross rod 4 and is parallel to the cross rod 4, a torsion spring which is connected with the swinging block 32 and is used for providing assistance for the resetting of the swinging block 32 is installed on the rotating shaft 31, and when the swinging block 32 is abutted against the baffle 5, the torsion spring is in a force accumulation state; when the torsion spring is in a natural state, a space is reserved between one end of the swinging block 32, which is positioned below the baffle 5, and the baffle 5, the upper side of the V-shaped bayonet a in the swinging block 32 is positioned on one side of the moving track of the cross rod 4, and the lower side of the V-shaped bayonet a is positioned on the moving track line of the cross rod 4.
