Embodiment Construction

[0022] Such as figure 1 As shown, this special equipment has a frame structure composed of a base 8, left and right uprights 20 and 21, and a cross beam 1. The equipment is also equipped with a level adjustment device 9, which is composed of 4 screws, lock nuts and pressure blocks arranged on the legs of the base. The level adjustment device 9 is supported on the ground and can be adjusted by rotating the 4 screws. The horizontality keeps the columns 20, 21 and the linear guide 12 upright to ensure that the special equipment can also perform normal milling work on the ground that is not flat enough. A lifting platform 10 is arranged between the left and right upright columns 20 and 21, and two screw rods 11 that are connected to the lifting platform and drive the lifting platform to move up and down are arranged on both sides of the lifting platform. Sliders (not shown) are provided on both sides of the lifting platform 10, and slide along the two linear guides 12 inside the le...

Abstract

Large-scale hydrogenerators belong to heavy and major equipment of special purposes. Hydropower stations have no machine tool that can process such heavy and major components on site. Therefore, processing equipment special for site processing of a hydrogenerator rotor spider stud needs to be developed. In order to make up the deficiency, the invention provides special and convenient processing equipment specifically for large-scale hydrogenerator rotor spider studs.

Description

Technical field [0001] The invention belongs to the field of hydroelectric generator processing. [0002] Background technique [0003] Large hydroelectric generators are heavy-duty and major special equipment. The rotor support in the hydro-generator has a diameter of more than ten meters, its height is more than 3.5 meters, and its weight is more than 160 tons. Such a large and heavy rotor support cannot be transported over long distances by road or railway, so it is large The rotor bracket of the hydro-generator is transported in a split manner, and then assembled and welded after reaching the hydropower station. However, due to welding deformation, the accuracy of the generator rotor bracket after welding cannot meet the installation requirements, so the rotor bracket needs to be machined to meet the installation size requirements after the assembly welding is completed. [0004] There is no machine tool capable of processing such heavy and important parts at the hydropower st...
