The utility model relates to a rope ladder, especially a shaft tunnelling safety rope ladder. When the device is applied to shaft excavation and shaft deepening, personnel can safely evacuate after failures such as sudden power failure and lifting during shaft excavation are prevented.
Background
When a vertical shaft is excavated and a vertical shaft is deepened, in order to prevent personnel from safely evacuating after failures such as sudden power failure, lifting and the like occur during the driving of the vertical shaft, safety facilities need to be installed in the vertical shaft, so that the vertical shaft driving safety rope ladder is manufactured, and the technical problem which needs to be solved at present is solved.
Disclosure of Invention
The utility model aims to solve the technical problem that a shaft tunnelling safety rope ladder is provided.
The technical proposal of the utility model for solving the technical problem is that:
a shaft tunneling safety rope ladder comprises two steel wire ropes arranged in parallel, two ends of each steel wire rope are connected with fixed rope protecting rings used for fixing the rope ladder through rope clamps, and pedal cross rods with intervals suitable for people to go up and down are uniformly distributed between the two parallel steel wire ropes.
As a preferred scheme of the utility model, pedal horizontal pole be stud, with wire rope through the people for counter-force and with the head of bolt stopper in the middle of wire rope, fixed stud and the wire rope of both sides with packing ring and nut.
As a preferred scheme of the utility model, stud be ordinary stud, at the head with the bolt plug in wire rope to preceding at first precession a nut call interior rum, cluster last packing ring call interior packing ring, then with the head of bolt plug in wire rope in the middle of, cluster last packing ring call outer packing ring again, and it calls outer nut to spin up a nut again, stud passes through interior rum, interior packing ring, outer packing ring and outer nut at both ends and wire rope are fixed.
As a preferred scheme of the utility model, stud be double-diameter stud be stud from taking the inner washer, directly fill in the wire rope with the head of bolt in the middle of, cluster a packing ring, a nut of screwing on again, double-diameter stud is fixed with wire rope through the packing ring and the nut at both ends.
As an optimal scheme of the utility model, be equipped with the round pin shaft hole at stud's end, be provided with the split pin in the round pin shaft hole.
The utility model discloses a use method:
will the utility model discloses an on one end was fixed in shaft pit shaft lower floor platform sling stand, folding receipts were rolled up at ordinary times, were put on lower floor's platform sling, and occupation space is little, when needing to use (after having a power failure suddenly and promoting etc. broke down), will the utility model discloses a vertical below of other end to platform sling below working face, personnel can withdraw to shaft pit shaft platform sling safely by the safe rope ladder.
Compared with the prior art, the utility model is made of steel wire ropes, has few parts, light weight, simple structure and easy manufacture; the use is light, flexible, small in occupied space and safe; can be folded, rolled or lengthened at any time, and is convenient to assemble, disassemble, use and transport.
