The end is fixed in the groove through a cushion block T-shaped groove, and the cushion block is detached by using the impact force of the power-assisted sleeve to the limiting block. The utility model overcomes clearance diminishes behind rotor tip coil die mould back cushion, and frictional force is big, and the limited scheduling problem of operating space has realized that high-efficient dismantlement rotor tip cushion convenient, the utility model discloses the commonality is strong, is applicable to various units, simple structure, labour saving and time saving.

Description

Turbo generator rotor cushion dismounting device

Technical Field

The utility model relates to a turbo generator field especially relates to a turbo generator rotor cushion dismounting device.

Background

In the process of assembling a rotor winding of the turbonator, a cushion block needs to be assembled between a rotor end coil and a rotating shaft and is used for profiling the rotor end coil. In order to achieve the purpose of profiling the coil at the end part of the rotor, the coil needs to be compressed by the rotor end pressure ring device, so that the gap between the cushion blocks is compressed, the friction force is increased, the operation space is limited, and the cushion blocks are difficult to disassemble.

Disclosure of Invention

The utility model aims to overcome above defect, design a turbo generator rotor cushion dismounting device, through this device, can dismantle rotor tip cushion high-efficiently conveniently, solve because of the limited and too big difficult problem that leads to the unable dismantlement of cushion of operating space. The technical scheme of the utility model is that: the power assisting device comprises an end head, an extension rod, a power assisting sleeve, a limiting block and a handle, wherein the end head is welded with the extension rod, the limiting block is fixed at the tail part of the extension rod, the power assisting sleeve is positioned between the end head and the limiting block, and the handle is fixed on the limiting block.

In the device for dismounting the rotor cushion block of the steam turbine generator, the inner diameter of the power-assisted sleeve is larger than the diameter of the extension rod, and the outer diameter of the power-assisted sleeve is smaller than the diameter of the limiting block.

Technical effects

The utility model provides a turbo generator rotor cushion dismounting device uses with the cushion cooperation after the change structure, and it is big to have solved cushion frictional force, and the restricted problem that leads to the unable dismantlement of cushion of operating space. The disassembly efficiency is high, the disassembly tool can be universally used for various units, the structure is simple, and time and labor are saved.

1-end head; 2-an extension rod; 3-a power-assisted sleeve; 4-a limiting block; 5-a handle; 6-cushion block; 7-shaped groove.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 and 2, the structure of the cushion block 6 is changed, and a T-shaped groove 7 is processed in the outer side direction of the assembled machine, wherein the size of the T-shaped groove 7 is designed to be matched with the end head 1 of the dismounting device. During the dismantlement, end 1 with dismounting device is deep in the same direction as T type groove 7 upper end, and end 1 stretches into the inslot back, carries out 90 rotations with end 1 through rotatory handle 5, makes its card in T type groove 7, and at extension rod 2 within ranges, slip helping hand sleeve 3 utilizes helping hand sleeve 3 to stopper 4's impact, realizes the impact of end 1 to the cushion, produces outside pulling force when making the cushion produce the vibration to reach the purpose of dismantling the cushion.

Finally, the scope of protection of the present invention is not limited to the embodiments described above. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
