Abstract
A levelness adjusting cushion block special for measuring the roundness of a generator rotor comprises a double-leg wedge-shaped sliding block, a double-slide-way wedge-shaped base matched with the double-leg wedge-shaped sliding block, an adjusting screw rod and two fixing screws. The invention has simple and symmetrical structure, uniform stress of the sliding block, low manufacturing cost and easy operation, the use of the invention not only ensures that the levelness of the generator rotor is conveniently, easily and quickly adjusted and the levelness of the generator rotor is adjusted with higher precision, but also ensures that the extra-large part of the generator rotor is safe in the adjusting process because the sliding block runs stably, thereby meeting the requirement of the operation specification and laying a solid foundation for accurately measuring the roundness of the generator rotor.
Description
Technical Field
The invention relates to auxiliary equipment for overhauling a generator rotor of a large hydropower station, in particular to a levelness adjusting cushion block special for measuring the roundness of the generator rotor.
Technical Field
The rotor of the generator is an important component of a generator set of a large hydropower station, and the roundness of the rotor of the generator is likely to change under the influence of factors such as electromagnetic force, mechanical force and the like in the long-term operation process, so that the rotor of the generator needs to be lifted out to measure the roundness in the overhaul process of the generator, the rotor of the generator is firstly horizontally placed on a group of buttresses, but the height of each buttresses cannot be absolutely unified due to the influence of inconsistent mechanical conditions and basic conditions, so that the rotor of the generator placed on the buttresses cannot reach the horizontal state, the existing solution is to place copper skin pads on the buttresses, but only some rough adjustments are carried out on the levelness of the rotor of the generator, so that the accuracy of the roundness measurement of the rotor of the generator is reduced, and problems cannot be solved in time, the phenomenon that the generator rotor operates with faults happens occasionally, and accident potential is formed.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a special adjusting cushion block for solving the problem that a rotor placed on a buttress cannot reach a horizontal state due to non-uniform height of each buttress when the roundness of a generator rotor is measured.
The purpose of the invention can be realized by the technical scheme that the device is arranged on a buttress and is used for assisting a generator rotor arranged on the buttress to reach an adjusting cushion block in a horizontal state when the roundness of the generator rotor is measured, namely the levelness adjusting cushion block special for measuring the roundness of the generator rotor is composed of a double-leg wedge-shaped slide block, a double-slide-way wedge-shaped base matched with the double-leg wedge-shaped slide block, an adjusting screw rod and two fixing screws, wherein the lower part of the joint of the front end and the double legs of the double-leg wedge-shaped slide block is provided with a thread sleeve matched with the adjusting screw rod and is positioned between two slide ways of the double-slide-way wedge-; the double-slideway wedge-shaped base is provided with a fixing boss at the front end, blocking edges are arranged on two sides of the fixing boss, an adjusting screw rod is arranged in the center of the fixing boss at the front end to arrange a bayonet, and a vertical fixing screw hole is respectively arranged on two sides of the arranging bayonet and used for being installed on the buttress through a fixing screw. When the levelness adjusting cushion block special for measuring the roundness of the generator rotor is used, the levelness adjusting cushion block is respectively arranged on each buttress through the fixing screws, and after the rotor of the generator is placed on the levelness adjusting cushion block, the adjusting screw rods of the adjusting cushion blocks on each buttress are rotated by using the spanner, so that the generator rotor placed on each buttress can be conveniently, easily and rapidly brought to a horizontal state.
The levelness adjusting cushion block special for measuring the roundness of the generator rotor, provided by the invention, has the advantages of simple and symmetrical structure, uniform stress on the slide block, low manufacturing cost and easiness in operation, can be used for conveniently, easily and quickly adjusting the levelness of the generator rotor and ensuring higher adjusting precision of the levelness of the generator rotor, and can ensure the safety of a super-large component, namely the generator rotor, in the adjusting process due to the stable operation of the slide block, meet the requirement of the operation specification and lay a solid foundation for accurately measuring the roundness of the generator rotor. The invention has important significance for reducing the labor intensity of workers, improving the working efficiency and improving the quality of maintenance work.
