Abstract
The invention provides a turbonator disassembling and assembling system. The turbonator disassembling and assembling system comprises a crown block device used for hoisting a turbonator rotor and a tackle assembly used for sliding the turbonator rotor. The tackle assembly comprises a sliding rail arranged next to a turbonator and a tackle arranged on the sliding rail in a slidable mode. The tackle is provided with a stable groove designed to be of a smooth arc structure, and an arc-shaped cover is detachably arranged on the upper side of the stable groove. The tackle assembly is arranged at the turbonator end and used for supporting and moving the rotor, and therefore the problem that traction force for sliding the rotor is so large that the rotor fails to move reliably is solved. The tackle assembly plays a role in lifting the excitation end of the rotor, the traction direction of the tackle assembly is consistent with the axis of the rotor, the tail of a rotor spindle is prevented from bearing bending moment, and equipment safety is guaranteed. The tackle and a guide rail are combined, so that the situation that the excitation end of the rotor is lifted by a rope, the walking rotor is not stable inside a stator, and a stator core is damaged by collisions is avoided. External tackle sizing blocks are lowered, so that load bearing of a journal bracket and load bearing of a supporting plate are switched.

3, step 3:
(1) when Journal bracket arrives vapour end arc skateboard end, below rotor body, fill in supporting plate, supporting plate leaves retaining ring and is about 100mm.
(2) decline lifting rope, and reducing outer little height, to make rotor encourage end lower slightly, weight is transferred on supporting plate by Journal bracket, continues to advance by encouraging end traction, and rotor weight is carried by supporting plate.
4, step 4:
(1) continuing to advance by encouraging end traction, stopping when core ends is about 700mm until encourage inside end retaining ring.
5, step 5:
(1) hang high rotor and encourage end, raising outer little height, to make rotor encourage end slightly high, and lifting rope changes and hangs to vapour end, supporting plate, arc skateboard, iron core baffle is extracted out to encouraging end respectively with nylon rope.
(2), after pumping supporting plate, arc skateboard, iron core baffle, traveling crane rotor vapour end, encourages end and continues the outer dolly of traction, carry out rotor to final position.
(3) vapour side shaft journal bracket turn over and hang.
6, step 6:
(1), after rotor arrives final position, train operation adjustment rotor height of lift, ploughs under second spheric seating of vapour end bearing and bearing in bearing pedestal.
(2) install rotor to complete, can load onto and encourage end bearing block and bearing.Encouraging end rotor as turned over watt needs, one can to keep off outside lifting trunnion.
7, rotor step is extracted out and to install sequence of steps contrary, (step 6---step one).
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
