Embodiment Construction
[0011] see Figure 1-Figure 4 , the present invention comprises cage 1 and hoisting device, and hoisting device has hoisting steel rope 10, and one end of hoisting steel rope 10 is fixed on the winch on the ground, and the pulley 11 on the hoisting cage beam 2 of the hoisting cage top that the other end walks around serves as hoisting main rope. Its key technology is to install the reel 8 through the reel shaft 20 at the two ends of the hanging cage beam 2, wind the safety steel rope 9 on the reel 8, and fix the other end of the safety steel rope 9 on the fixed anchor point above the shaft. Rope 9 is freely retractable along with the rotation of reel 8. The braking device is fixed at one end of the reel 8. The braking device is to fix the braking tooth 7 at one end of the reel 8. The braking tooth 7 rotates with the reel 8. The braking tooth 7 is fixed on the reel through the brake sliding seat 4. On the bearing seat 6, a brake card 5 is arranged in the brake card slide seat...

The invention relates to a safe perpendicular conveying device, in particular to a vertical shaft suspension cage. The drum type safe suspension cage comprises a suspension cage body and a lifting steel rope. The drum type safe suspension cage is characterized in that drums are arranged at two ends of a suspension cage transverse beam, safe steel ropes are wound on the drums, and the other ends of the safe steel ropes are fixedly arranged on fixing anchor points above a vertical shaft. A braking device is fixedly arranged at one end of each drum, a ratchet mechanism is arranged on a drum shaft at the other end of each drum through a friction coupler, the tail end of each drum shaft is connected with a flexible shaft through a flexible shaft coupler, and the other end of each flexible shaft is fixedly connected with a pulley shaft. The drum type safe suspension cage has the advantages that the safe steel ropes and the safe steel rope drums are arranged on the suspension cage transverse beam on the top of the suspension cage body, the suspension cage can be prevented from falling down when the lifting steel rope is broken, safety hazards of working staff is reduced, and working efficiency is improved. The problems that material conveying by the suspension cage is not safe and losses happen to personnel and equipment are solved, and safe and quick conveying of construction materials of the vertical shaft from top to bottom is achieved.
Description
technical field [0001] The invention relates to a safe vertical transportation device, in particular to a vertical shaft cage, and belongs to the technical field of construction. Background technique [0002] At present, in the construction of water conservancy and hydropower projects, simply using two steel wire ropes to lift the cage to transport materials, the construction safety risk is extremely high, and it poses a great threat to the life safety of the construction workers. It is necessary to take protective measures to prevent the cage from falling to ensure the operation of the cage Safety. Contents of the invention [0003] The problem to be solved by the present invention is to provide an anti-fall safety cage for the above deficiencies. Its technical scheme is as follows: [0004] It comprises a cage and a lifting device, the lifting device has a hoisting steel rope, one end of the hoisting steel rope is fixed on the winch on the ground, and the other end goe...
