Abstract
The utility model discloses a hydroelectric set rotor hoist device comprises hanging beam box, lug, connection U-shaped ring, fixing bolt, adjusting bolt, adjustment fixed block. The utility model has the advantages of simple structure, convenient and practical, the reliability is high, all can use to different hoist and mount weight and hoist and mount radius. The utility model discloses when can be applied to hydroelectric set installation and maintenance, the hoist and mount operation of hydroelectric set rotor.
Description
Technical Field
The utility model relates to a hydraulic generator field especially relates to a hydroelectric set rotor hoist device.
Background
The hydroelectric generating set rotor is relatively heavy, the structure is complex, the hoisting operation can not be carried out only by using hanging strips or lifting ropes, a special hoisting device is needed for hoisting, the main shaft is used as a main stress component when the rotor is hoisted, particularly, in the installation process, the condition of existence of the rotor is considered, the lifting lugs are required to be replaced, so that different hoisting radiuses in different states are ensured, and for the rotors with different weights, the connecting U-shaped rings with different thicknesses are required to be replaced for ensuring the hoisting safety, and the limiting conditions are provided for the design of the hoisting device. Therefore, in order to guarantee the hoisting of the rotor of the water turbine generator set, a rotor hoisting device is necessary to be developed aiming at the structural characteristics of the rotor, the hoisting device is convenient and reliable and is easy to hoist, so that the hoisting steps of the rotor of the generator are reduced, the installation period is saved, and the installation cost is reduced.
When the hydroelectric generating set is installed and overhauled, the rotor needs to be hoisted, so the service cycle of the hoisting device is generally long, the reliability of the hoisting device is required to be high, the distance between the stator and the rotor of the hydroelectric generating set is small when the stator and the rotor are in a foundation pit, the position can be corrected by a small distance in the hoisting process, if the position is corrected only through the lifting hook, the position correction cannot be completed, and certain difficulty is brought to the installation and the hoisting of the rotor.
Disclosure of Invention
In view of this, the utility model aims at providing a hydroelectric set rotor hoist device compares hydroelectric set rotor hoist device's original structure type form, the utility model has the advantages that, simple structure, convenient and practical can come the correction to the less distance in hoist and mount center by adjusting bolt. The technical scheme of the utility model is that: the lifting beam box body is connected with the lifting lug in a threaded manner, the connecting U-shaped ring is connected with the lifting beam box body in a fixed bolt manner, the adjusting fixed block is welded on the side part of the lifting beam box body, a threaded hole is formed in the adjusting fixed block, and the adjusting bolt is installed.
In the rotor hoisting device of the hydroelectric generating set, the number of the adjusting fixed blocks is 4, and the adjusting fixed blocks are welded on the front side and the back side of the hanging beam box body.
In the hoisting device for the rotor of the hydroelectric generating set, the connecting U-shaped rings are 2 and semicircular.
Technical effects
Compared with the prior art, the beneficial effects of the utility model are that:
1. simple structure, convenient and practical, the reliability is high, can come to carry out the artificial correction of less distance to the hoist and mount center by adjusting bolt to prevent the scraping of hoist and mount in-process stator and rotor and collide with.
2. With the mode of connecting U-shaped ring and lug change, guarantee all can accomplish the hoist and mount operation to the rotor of different weight, also can adjust the hoist and mount radius, the weight that can hoist and mount is big, and the structure atress is reasonable, can guarantee that hoist device satisfies the operation requirement to the rotor of isostructure.
