Assembled aluminium alloy scaffold maintenance platform used for hydropower station unit

Abstract

The invention provides an assembled aluminium alloy scaffold maintenance platform used for a hydropower station unit. The cross section of the maintenance platform is in the shape of a regular hexagon; the maintenance platform comprises vertical bracing frames, crossbeams, a pedal and guardrails; six vertical bracing frames are arranged, and form a rectangular framework structure, and each vertical bracing frame comprises an inner vertical bar, an outer vertical bar, and cross bars connected between the inner vertical bar and the outer vertical bar; each crossbeam is fixedly connected between two adjacent vertical bracing frames, and the crossbeams connect and fix the vertical bracing frames to form a regular hexagonal prism framework structure; six guardrails are arranged, two sides of each guardrail are provided with spring locks, each guardrail is installed on the extension positions of the tops of two adjacent outer vertical bars, and the six guardrails form a regular hexagon together. The assembled aluminium alloy scaffold maintenance platform gives consideration to flexibility and safety of maintenance work, and is humanized in design, the maintenance efficiency is improved, and the safety of maintenance workers can be well guaranteed.

Description

technical field [0001] The invention provides an aluminum alloy scaffold maintenance platform, in particular to an assembled platform used for maintenance of main shafts, flanges and auxiliary structures of generators in hydropower stations. Background technique [0002] my country has a vast territory and numerous rivers. Hydropower is currently the most important source of power supply in my country. At present, my country has a very large number of hydropower stations. The most critical part of a hydropower station is the unit. The main shaft of a hydropower station unit is generally a high-quality steel overall hollow structure, and its main function is to transmit torque. The commonly used main shaft diameter is 1150mm. The diameter of the flange connecting the main shaft of the generator motor and the major shaft of the pump turbine on the upper part of the waterwheel room of the unit is 1900mm, and the upper part of the flange connection is the generator motor and its...
