Abstract

The invention provides an elevation type tail water overhauling platform, which comprises an elevating gear, a platform main girder, a platform auxiliary girder, a support girder and a platform plate. The elevating gear is connected and fixedly arranged on the platform main girder, the platform auxiliary girder is crossly fixed on the platform main girder, the support girder is fixedly arranged on the platform main girder and / or the platform auxiliary girder, both ends of the support girder are respectively connected and fixed on the platform main girder and / or the platform auxiliary girder, and the platform plate is fixedly arranged on the platform main girder, the platform auxiliary girder and the support girder. The platform causes a two-dimensional plane working position to expand to a three-dimensional solid working position by the elevation and descent of the platform, thus facilitating the inspection, maintenance and overhauling of any part such as tail water pipe inner wall and hydroturbine vanes.

Description

technical field [0001] The invention belongs to the technical field of maintenance and construction of hydropower equipment, and in particular relates to a device for installing and using the inner wall of a draft tube of a hydropower plant and the maintenance of a turbine blade and a method for using the device. The device is especially suitable for the inner wall of a draft tube of a hydropower plant And the inspection, maintenance and repair of turbine blades. Background technique [0002] At present, the maintenance of the inner wall of the draft tube of the hydropower plant and the blades of the turbine generally adopts the traditional fixed double-layer maintenance platform for maintenance, that is, the beam hole opened in the draft tube in advance penetrates two profiled steel main girders, and then erects the profiled steel girders on the main girders. Form a temporary platform, or directly use the aluminum alloy tailrace platform through the beam hole, as an inspect...
