Description

Device for dismounting pin of rotor coupling of steam turbine generator

Technical Field

The utility model belongs to the technical field of auxiliary tools of turbonators, and particularly relates to a device for dismounting a pin of a rotor coupling of a turbonator.

Background

At present, tools used for dismantling a rotor coupling pin of a steam turbine generator are a copper bar and hammer foundation bench worker tool which is purely manually adopted, and a special hydraulic wrench. Although the two tools meet the requirement for dismantling the pin of the rotor coupling of the steam turbine generator, the basic fitter tool is simple, does not have a fixed standard, is dismantled manually by means of pure hands, and is difficult to dismantle and slow in speed; the special hydraulic wrench saves manpower, but is expensive, has various parts and high defect rate, needs to be maintained regularly, and needs to be connected with a temporary power supply. Therefore, a dismantling tool which is simple to manufacture, simple to operate, labor-saving, low in price and free of electricity is specially designed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a device for removing a rotor coupling pin of a steam turbine generator, which aims to solve the problems.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the utility model provides a turbo generator rotor shaft coupling pin demolish device, includes the sleeve, the sleeve is the open end towards the one end of shaft coupling pin, and the other end is the blind end, sets up the through-hole on the blind end, wears to establish the pin in the through-hole, and the tip that the pin is located the sleeve sets up link I, and the one end that the pin is located the sleeve outside sets up link II, sets up hexagon nut on the link II.

In order to further realize the utility model, a thrust bearing is arranged on the outer wall of the closed end, the circle center of the thrust bearing is overlapped with the circle center of the through hole, and the inner diameter of the thrust bearing is smaller than the diameter of the through hole. The thrust bearing is arranged to ensure that the hexagonal nut and the sleeve can rotate relatively when the hexagonal nut is fastened.

In order to further realize the utility model, the pin is arranged in the thrust bearing in a penetrating way, and the pin is matched with the thrust bearing.

In order to further realize the utility model, T-shaped threads which are matched with each other are arranged between the hexagonal nut and the connecting end II. The screw thread adopts positive T type screw thread, improves tensile moment to prevent that link I and shaft coupling pin junction from becoming flexible.

In order to further realize the utility model, the connecting end I and the pin hole are provided with mutually matched threads.

To further realize the utility model, the diameter of the sleeve is not smaller than that of the coupling pin hole.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model changes the mode that a basic fitter tool has no fixed reference and is purely manual, fixes the connecting end I of the pin on the coupling pair wheel by a semi-mechanical structure of the fixed reference to play a role of fixing a dismantling tool, adopts other tools to rotate the hexagonal nut, can utilize pin drawing force to replace the pure manual, can easily dismantle the coupling pin by a single person, and solves the problems of no fixed reference, pure manual, difficult dismantling and slow speed.
