Description

TECHNICAL FIELD

[0001] The utility model relates to water conservancy and hydropower technology field, concretely relates to an easy operation type tail water overhauling platform. BACKGROUND

[0002] For the axial flow variable pitch unit, the runner chamber diameter is large, and the blade of the axial flow variable pitch unit is located on the upper part of the runner chamber. Due to the scouring of water flow to the blade, impurities in water can cause destructive damage to the blade, so regular maintenance and replacement when the blade is damaged are required. The runner chamber is also subjected to water scouring all the year round, and the wear condition is also relatively serious, so it also needs to be checked and repaired. The conventional overhauling platform is built by building steel structure from the bottom, and it is built layer by layer to reach the overhauling operation surface, which is laborious and time-consuming, and the operation is not convenient, and there is a certain risk in dismounting and building.

[0006] The pressing mechanism is composed of a shell and a roller, the roller is arranged in the shell, the lower surface of the roller is in contact with the upper surface of the support rod, and the bottom of the shell is fixed to the ground;

[0007] The supporting mechanism is composed of a base and a ball, the ball is arranged on the base, the upper end of the ball is in contact with the lower surface of the support rod, and the bottom of the base is fixed to the ground.

[0008] While the above technical scheme is adopted, the utility model can also adopt or combine the following technical schemes:

[0009] As a preferred technical scheme of the utility model: the other end of the support rod is arranged in the reserved perforation in the runner chamber.

[0010] As a preferred technical scheme of the utility model: the support rod is a channel steel.

[0011] As a preferred technical scheme of the utility model: a steel plate or a wooden plate is arranged on the platform overhauling frame.

[0012] As a preferred technical scheme of the utility model: the bottom of the shell is fixed to the ground through expansion bolts.

[0013] As a preferred technical scheme of the utility model: the bottom of the base is fixed with the ground through expansion bolts.

[0014] The utility model provides an easy operation type tail water maintenance platform has the following beneficial effects: through setting down pressure mechanism, supporting mechanism passes through down pressure structure downwardly and down pressure, and supporting mechanism supports upwardly, make maintenance platform build more simple, just a small amount of personnel can easily complete platform building, need not complex steel structure building and multilayer platform building, save a lot of manpower and material resources, platform maintenance frame can be directly worn on the supporting rod, need not carry out tedious welding or bolt connection, further simplify the building process, improve the efficiency, use less parts can complete the building of maintenance platform, shorten the unit overall maintenance period, simultaneously, tail water maintenance platform can be removed and reused, avoid the time and cost waste brought by repeated building, because the platform building and removal process are simple, effectively shorten the unit overall maintenance period, improve the unit operation efficiency.
