Detailed Description
All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example (b): referring to fig. 1-4, the main components of the present invention are: the device comprises a device mounting plate 1, wherein an efficient braking anti-falling structure for the elevator is mounted on the device mounting plate 1;

the mounting seat 2 is installed on the front wall face of the equipment mounting plate 1, the mounting shell 3 is installed on the mounting seat 2, the mounting cavity 4 is opened at the inner position of the mounting shell 3, the brake transmission shaft 5 penetrates through the equipment mounting plate 1 to be installed on the mounting seat, the brake gear 6 is installed at the rear end position of the brake transmission shaft 5, the cone drum brake 7 is installed in the mounting cavity 4, the centrifugal speed limiter 8 is installed in the cone drum brake 7, the centrifugal block 9 is installed on the centrifugal speed limiter 8, the brake transmission shaft 5 is connected with the centrifugal speed limiter 8, the pressure spring 10 is installed at the front position in the mounting cavity 4, the pressure spring 10 is connected with the cone drum brake 7, the fixing plate 11 is installed at the front wall face of the equipment mounting plate 1 and close to the right position, and the power supply device 12 is installed on the fixing plate 11.
It should be noted that, when a gear cone drum-shaped anti-falling assembly is used, when a suspension cage of a construction elevator falls at a high speed, a centrifugal block 9 inside an anti-falling safety device generates centrifugal force due to the increase of the sliding speed, the centrifugal block 9 is completely opened due to the suddenly generated centrifugal force to drive a centrifugal speed limiter 8 to start, the centrifugal speed limiter 8 installed inside a cone drum-shaped brake 7 drives a brake transmission shaft 5 to rotate at a high speed by matching with a pressure spring 10 and the cone drum-shaped brake 7, the brake transmission shaft 5 rotates to drive a brake gear 6 to rotate, and the brake gear 6 rotates to provide a reverse force to start emergency braking on the suspension cage of the elevator due to the meshed state of the brake gear 6 and a brake rack on an external guide rail frame when the elevator falls.
In one embodiment, the present invention provides a friction drag reducing assembly comprising: the device comprises a fixed seat 13, a pair of driving hydraulic cylinders 14, a moving plate 15, an installation box 16, three friction wheels 17 and a pair of resistance friction blocks 18;

When the elevator cage drops rapidly when the resistance friction anti-falling assembly is used, the output end of the driving hydraulic cylinder 14 mounted on the fixed seat 13 extends out, the driving hydraulic cylinder 14 drives the movable plate 15 to move outwards, the movable plate 15 drives the installation box 16 to move outwards, the friction wheel 17 mounted on the installation box 16 and the pair of resistance friction blocks 18 abut against an external braking track, and the dropping speed of the cage is reduced through high-pressure friction force, so that auxiliary braking is realized.
