Abstract
The utility model provides a runner hanging structure of a large-sized impulse water turbine, aiming to solve the problems that for the runner hanging structure of the large-sized impulse water turbine in the prior art, a runner screw hole is not easily aligned with a main shaft screw hole, and the potential safety hazard exists and the like. The runner hanging structure of the large-sized impulse water turbine comprises a chain hanger, a tray and a hoisting fork head, wherein the hoisting fork head is connected with the center of the tray and the tray is placed at the center of the bottom of a runner; the chain hanger passes through a central through hole of a main shaft; and one end of the chain hanger is connected with a travelling crane and the other end of the chain hanger is connected with the hoisting fork head. The runner hanging structure of the large-sized impulse water turbine has the beneficial technical effects of sufficiently utilizing the hoisting capability of the travelling crane, guaranteeing the accurate alignment of the rubber and the main shaft screw hole, and eliminating the potential safety hazard that a steel wire rope which is used for bundling a water bucket is easy to slide off.
Description
Technical field
The utility model relates to large-scale impact type waterturbine wheel hoisting technology, specially refers to a kind of large-scale impact type waterturbine wheel hoisting structure.
Background technology
The impact type vertical shaft water turbine winches to spindle flange with runner from the dolly of inspection platform when mounted and is attached thereto, dismantles to dolly from spindle flange during maintenance, and the about 2m of sling height, runner weight is about 3～15 tons.Because the space is narrow and small in the casing, can't use large-scale suspender or automatic rising-sinking platform, lifting is difficulty comparatively.Four hanging bolt holes that the large-scale impact type waterturbine wheel hoisting structure of prior art is provided with on inner top cover when utilizing the unit design; Suspension ring are fixed on the inner top cover; Bucket place with runner ties with steel rope; Lifting steel rope one end connects four hanging bolts, and the other end is connected bottle gouard moved by hands through runner with suspension ring, with four bottle gouards moved by hands runner is lifted respectively when adopting the manual interlocking.The large-scale impact type waterturbine wheel hoisting structure of prior art has been fixed four orientation of runner, and runner can not rotate when runner connects with main shaft, and the runner screw is not easy to aim at the main shaft screw.In addition, when runner lifted by crane near setting height(from bottom), the distance of runner and suspension ring hook diminished, and rigging lifting angle strengthens, and there is potential safety hazard in the easy slippage of steel rope of binding bucket.
Summary of the invention
Be not easy to aim at the main shaft screw and have problem such as potential safety hazard for overcoming runner screw that the large-scale impact type waterturbine wheel hoisting structure of prior art exists, the utility model proposes a kind of large-scale impact type waterturbine wheel hoisting structure.The large-scale impact type waterturbine wheel hoisting structure of the utility model comprises chain suspender, pallet and lifting jaw; Wherein, The lifting jaw is connected the pallet center; Pallet is placed on runner bottom centre, and the chain suspender passes alignment of shafts through hole one end and is connected on the driving crane, and the other end connects the lifting jaw.
The useful technique effect of the large-scale impact type waterturbine wheel hoisting structure of the utility model is the crane capacity that makes full use of the driving crane, guarantees the accurate contraposition of runner and main shaft screw, has eliminated the potential safety hazard of the easy slippage of binding bucket steel rope.
Description of drawings
Accompanying drawing 1 is the scheme drawing of the large-scale impact type waterturbine wheel hoisting structure of prior art;
Accompanying drawing 2 is scheme drawings of the large-scale impact type waterturbine wheel hoisting structure of the utility model.
Below in conjunction with accompanying drawing and specific embodiment further specifying to the large-scale impact type waterturbine wheel hoisting structure of the utility model.
The specific embodiment
Accompanying drawing 1 is the scheme drawing of the large-scale impact type waterturbine wheel hoisting structure of prior art, and among the figure, 1 is inner top cover, and 2 is suspension ring, and 3 is runner, and 4 are the lifting steel rope.Can know by figure; Four hanging bolt holes that the large-scale impact type waterturbine wheel hoisting structure of prior art is provided with on inner top cover when utilizing the unit design; Suspension ring are fixed on the inner top cover, and the bucket place with runner ties with steel rope, and an end of lifting steel rope connects hanging bolt; The other end is connected bottle gouard moved by hands through runner with suspension ring, with four bottle gouards moved by hands runner is lifted respectively when adopting the manual interlocking.The large-scale impact type waterturbine wheel hoisting structure of prior art has been fixed four orientation of runner, and runner can not rotate when runner connects with main shaft, and the runner screw is not easy to aim at the main shaft screw.In addition, when runner lifted by crane near setting height(from bottom), the distance of runner and suspension ring hook diminished, and rigging lifting angle strengthens, and there is potential safety hazard in the easy slippage of steel rope of binding bucket.
Accompanying drawing 2 is scheme drawings of the large-scale impact type waterturbine wheel hoisting structure of the utility model, and among the figure, 5 is main shaft, and 6 is the chain suspender, and 7 is pallet, and 8 are the lifting jaw.Can know by figure; The large-scale impact type waterturbine wheel hoisting structure of the utility model comprises chain suspender 6, pallet 7 and lifting jaw 8; Wherein, lifting jaw 8 is movably connected in pallet 7 centers, and pallet 7 is placed on runner bottom centre; Chain suspender 6 passes alignment of shafts through hole one end and is connected on the driving crane, and the other end connects lifting jaw 8.The useful technique effect of the large-scale impact type waterturbine wheel hoisting structure of the utility model is the crane capacity that makes full use of the driving crane, adopts pallet that runner is held and lifted, and through driving crane lifting runner, makes its safety, steady, efficient.In addition, because the lifting jaw is movably connected in the pallet center, the chain suspender connects the lifting jaw again, and therefore, runner is rotatable in the lifting process, has guaranteed the accurate contraposition of runner and main shaft screw, has eliminated the potential safety hazard of the easy slippage of binding bucket steel rope.
