Technical Field

The utility model belongs to the technical field of hydroelectric power generation hydraulic turbine technique and specifically relates to an improve extracting tool device of horizontal mixed-flow hydraulic turbine runner.

Background

The horizontal mixed-flow turbine runner and the main shaft are matched by generally adopting taper fit, the runner is not frequently disassembled in the operation process, in addition, the contact surface is tightly matched in the installation process, the runner is difficult to disassemble, the runner is separated from the main shaft by means of a disassembling tool, and the residual task of disassembling is very simple after the runner is separated from the main shaft. In the process of detaching and separating the rotating wheel, the rotating wheel is difficult to detach from the main shaft due to narrow space, and a detaching tool is easy to damage.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an improve extracting tool device of horizontal mixed-flow water turbine runner to the defect that prior art exists, solve in the past the runner dismantle the dismantlement difficulty that exists and the problem that extracting tool easily damaged, this extracting tool still can prevent the runner problem that drops when the installation runner. The utility model discloses runner extracting tool both can conveniently dismantle and not fragile.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a kind of extracting tool apparatus which improves the runner of horizontal mixed-flow turbine, including:

the rotating wheel dismounting tool is provided with a bolt hole and is combined with the rotating wheel handle through a rotating wheel handle combining bolt;

and two axial ends of the telescopic ejection mechanism are respectively abutted against the rotating wheel dismounting tool and the main shaft.

Further, the runner extracting tool has still seted up the screw rod clearing hole, and the runner extracting tool passes through screw rod, nut and back lid and closes, but does not die, and the nut on the screw rod is the state of relaxing promptly, does not contact with the runner extracting tool, guarantees simultaneously that the bolt head that closes the bolt is closer to the runner extracting tool than the nut.

Further, the runner extracting tool is disc-shaped.

Further, the telescopic ejection mechanism is a jack.

Furthermore, the rotating wheel disassembling tool is provided with at least three bolt holes at equal angles, and the rotating wheel disassembling tool is provided with at least three screw rod through holes at equal angles.

Compared with the prior art, the utility model following beneficial effect has:

the dismounting tool not only can simply solve the difficulty of dismounting and separating the rotating wheel and the main shaft, but also can solve the problems that the space in the dismounting process is narrow and small and the dismounting tool is easy to damage, and can effectively prevent the rotating wheel from falling off in the separation process of the rotating wheel and the main shaft, and can also prevent the rotating wheel from falling off by closing the rotating wheel handle when the rotating wheel is mounted, so that the dismounting tool not only can meet the requirement of dismounting the rotating wheel, but also can provide convenience for mounting.

Drawings

Fig. 1 is a schematic structural diagram of the utility model discloses an improve extracting tool device of horizontal mixed-flow turbine runner.

In the figure: 1 screw rod, 2 nuts, 3 runner handle bolt, 4 runner extracting tools, 5 jacks, 6 runners, 7 main shafts and 8 rear covers.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution:

the rotating wheel dismounting tool 4 is provided with a bolt hole and is used for combining the bolt 3 with the rotating wheel handle through the rotating wheel;

and two axial ends of the telescopic ejection mechanism are respectively abutted against the rotating wheel detaching tool 4 and the main shaft 7.

Further, the runner extracting tool has still seted up the screw rod clearing hole, and the runner extracting tool passes through screw rod 1, nut 2 and 8 closeings of back lid, but not dead, and the nut on the screw rod is the relaxed state promptly, does not contact with the runner extracting tool, guarantees simultaneously that the bolt head that closes the bolt is closer to the runner extracting tool than the nut.

Further, the runner extracting tool is disc-shaped. The telescopic ejection mechanism is a jack 5.

The rotating wheel dismounting process: the runner disassembling tool 4 is used for combining the bolt 3 with the runner 6 through the runner, and the combination is a common term in the mechanical industry and means that two objects are connected together by a bolt or a screw; the turning wheel disassembling tool 4 is combined with the rear cover 8 through the screw rod 1 and the nut 2, but the turning wheel disassembling tool is not required to be dead, namely the nut on the screw rod is in a loose state and is not contacted with the turning wheel disassembling tool 4, meanwhile, the turning wheel disassembling tool 4 is not contacted with the rear cover 8, and the bolt head of the combined bolt 3 is ensured to be closer to the turning wheel disassembling tool 4 than the nut 2; with jack 5 upper and lower extreme promptly axial both ends push up respectively on extracting tool 4 and main shaft 7, extend jack 5, when reaching certain effort, runner 6 and main shaft 7 separation, runner 6 is in an instant of 7 separations with the main shaft, the runner can fall because of the influence of gravity, nevertheless because runner extracting tool 4 passes through screw rod 1, nut 2 closes with back lid 8, but not die, can not hinder the runner and dismantle, can also prevent the runner whereabouts, the most important process of runner dismantlement has been solved, the dismantlement process that follows can according to normal dismantlement.

The runner remover 4 can be a disc-shaped structure or other disc-shaped structures with hollows or a radiation frame structure and the like.
