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 utility model discloses simple structure, symmetry, slider atress are even, the cost is low, easy to operate, its use not only makes the adjustment to the generator rotor levelness become convenient, light, rapid, makes the adjustment precision to the generator rotor levelness higher, but also because the slider operates steadily, can guarantee this especially big part of generator rotor at the in-process safety of adjustment, satisfies its operating specification requirement, lays solid foundation for the circularity of this back accurate measurement generator rotor.
Description
Technical Field
The utility model relates to a large-scale power station generator rotor overhauls auxiliary assembly, especially a special levelness adjustment cushion of generator rotor roundness measurement.
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
An object of the utility model is to overcome above-mentioned prior art not enough, and provide a special adjustment cushion for solve when measuring the generator rotor circularity because of the highly non-uniform of each buttress and lead to placing the rotor on the buttress can not reach the problem of horizontality.
The purpose of the utility model can be realized by the technical proposal that the device is arranged on a buttress and is used for assisting the generator rotor placed on the buttress to reach the adjusting cushion block of the horizontal state when measuring the roundness of the generator rotor, namely the special levelness adjusting cushion block for measuring the roundness of the generator rotor, and the device consists of a double-leg wedge-shaped slider, a double-slide-way wedge-shaped base matched with the double-leg wedge-shaped slider, an adjusting screw rod and two fixing screws, wherein the lower part of the joint of the front double-leg wedge-shaped slider and the front double-leg is provided with a thread sleeve matched with the adjusting screw rod and is positioned between two slideways of the double-slide-way wedge-shaped base; 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 utility model provides a special levelness adjustment cushion of this kind of generator rotor roundness measurement, moreover, the steam generator is simple in structure, the symmetry, the slider atress is even, the cost is low, easy to operate, its use not only makes the adjustment to the generator rotor levelness become convenient, light, rapidly, it is higher to the adjustment precision of generator rotor levelness, and still because the slider operates steadily, can guarantee this especially big part of generator rotor at the in-process safety of adjustment, satisfy its operating specification requirement, solid basis has been put down for the circularity of this back accurate measurement generator rotor. The utility model discloses an use, all have important meaning to alleviateing staff intensity of labour, improving work efficiency, improving maintenance work quality.

Detailed Description
The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention.
Referring to the attached drawings, the embodiment of the utility model provides a special levelness adjusting cushion block for measuring the roundness of a generator rotor, which comprises a double-leg wedge-shaped sliding block 1, a double-sliding-channel wedge-shaped base 2 matched with the double-leg wedge-shaped sliding block, an adjusting screw rod 3 and two fixing screws (not shown in the figure), wherein the lower part of the joint of the front end and the double legs of the double-leg wedge-shaped sliding block 1 is provided with a thread sleeve 11 matched with the adjusting screw rod 3 and is positioned between two sliding channels 21 of the double-sliding-channel wedge-shaped base 2; the double-slideway wedge-shaped base 2 is provided with a fixing boss 23 at the front end, blocking edges 22 at two sides, an adjusting screw rod 3 is arranged in the center of the fixing boss 23 at the front end to arrange a bayonet, and a vertical fixing screw hole 24 is respectively arranged at two sides of the arranging bayonet and used for being installed on a 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 embodiment of the utility model provides a special levelness adjustment cushion of this kind of generator rotor circularity measurement, the regulation stroke of slider is 60mm, and the altitude mixture control volume can reach 5.25mm, can satisfy the technical requirement of generator rotor levelness adjustment.
