Climbing frame system and chain block device thereof

The utility model discloses a climbing frame system and a chain block device thereof. The climbing frame system comprises a climbing frame main body, a loop chain hoist and the chain block device, before the climbing frame system climbs along a building, the connecting structure at the end of the chain traction section is fixedly connected to the building, meanwhile, the extending end of the rope of the chain block device is connected to the traction section, then the loop chain hoist is started to gradually pull the traction section, so that part of the traction section is pulled to the non-traction section side, and the traction section is pulled to the non-traction section side. When the traction section acts, the extending end of the rope is always connected to the traction section and can synchronously act along with the traction section. When the climbing frame system ascends to a preset position, the chain block device is started to pull the rope to move upwards or downwards, and then the chain is grad
