Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by specific embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " including " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other units
Part or other parts.
Professional teams and groups prove by analysis, it is believed that original mounting means is hot jacket structure, it is necessary to using big intensity speed heat method
Processed, as shown in Figure 1 to Figure 3, the dismounting of Low Pressure Steam Turbine according to the utility model specific embodiment to taking turns
Instrument meets 40T with upper pulling force, and possesses adjustable and retractable amount not less than 600MM, possesses sufficient space and fixed pivot, it is ensured that
Two 280mm height hydraulics jack can place its between wheel, synchronous ascending.The Low Pressure Steam Turbine is torn open to wheel
The concrete structure for unloading instrument includes：Bearing plate 1, pull bar 2 and suspender 3.Wherein, bearing plate 1 passes through pull bar 2 with low pressure rotor to wheel
4 connections, intermediate gaps install hydraulic jack, and hydraulic jack is arranged on bearing plate and rotor center position, in jack pair
When bearing plate and rotor apply external force, bearing plate is together displaced outwardly together with low pressure rotor to wheel, makes to separate wheel with rotor.Should
