Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as any limitation to the present invention.

[0026] see figure 1 : the present invention is applied to the hydraulic structure that is provided with inclined arched trash rack 1, figure 1 One of the forms of the building is shown. From figure 1 It can be seen that the hydraulic structure is on the upstream surface (ie figure 1 middle left) adopts an inclined dam structure, and the direction of water flow is from the upstream to the downstream, that is, from the figure 1 From the middle left to the right, the water intake of the hydraulic structure is located on the upstream face. The bottom of the hydraulic structure is provided with a sill 7, the middle part is provided with an inspection platform 9 close to the upstream surface, the upper part is provided with a water intake tower top 10, and above the water intake tower top 10 is provided ...

Abstract

The invention discloses a tilting type arched trash rack hoisting device and method. According to the tilting type arched trash rack hoisting device, a tilting type rack groove is formed in the frontportion of a hydraulic structure and extends to an overhauling platform from a bottom sill, and a tilting type arched trash rack can vertically slide in the tilting type rack groove; a hoisting bracket is arranged on the overhauling platform, a locking beam is arranged on the position, located at the top of the tilting type rack groove, of the front end of the overhauling platform, and a fixed winch type starting and stopping machine is arranged on a platform where the water taking port tower top is located; and the fixed winch type starting and stopping machine hoist the tilting type arched trash rack through steering fixed pulleys arranged at the front end of the platform where the water taking port tower top is located. According to the tilting type arched trash rack effective hoistingmethod, the principle is feasible, and the structure is simple. A reasonable structure can be designed for the hoisting bracket according to the specific space of the overhauling platform, the flexibility is high, the tilting angle of the hoisting bracket and the tilting angle of the tilting type rack groove are consistent, and it can be ensured that the trash rack smoothly slides into the rack groove.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and in particular relates to a hoisting device and a hoisting method of an inclined arched trash rack. Background technique [0002] In some hydropower projects, according to the overall layout of the hub, only inclined arched trash racks can be installed at the water intake for power generation. Compared with the vertical plane trash rack, the inclined arched trash rack needs a larger hoist bent structure and maintenance platform space to meet the maintenance requirements. In the past, in consideration of saving investment, many projects did not set up permanent opening and closing maintenance equipment for the trash rack. After a certain year of operation, it was very inconvenient to overhaul the trash rack, and some even could not be repaired. Similar problems are often encountered in old power station renovation projects. Contents of the invention [0...
