Problems solved by technology

It can adjust the span of the sling by setting multiple pairs of hanger mounting holes on the beam, but it can only achieve stepwise adjustment, that is to say, the span of each pair of hanger mounting holes is still determined, so it cannot Meet the lifting requirements of other spans

Embodiment Construction

[0025] see Figure 1 to Figure 4 Summary of the invention: the present invention is a kind of steam turbine rotor hoisting tool, comprises beam 1, a pair of lower hangers 2, a pair of upper hangers 3 and hanger 4. Crossbeam 1 is " work " word crossbeam.

[0026] Such as figure 1 As shown, a lower hanger 2 is suspended on the crossbeam 1, which is arranged symmetrically with respect to the center of gravity of the crossbeam 1. The lower hanger 2 is equipped with a lower sling 6 for hanging the steam turbine rotor. The load capacity and geometric dimensions of the lower hanger 2 are designed according to the largest and heaviest rotor. as follows figure 2 As shown, the hanger 2 is a frame-shaped structure, and the shape inside the frame matches the section profile of the beam 1. The lower hanger is set on the beam 1 and is movably connected with the beam 1, and can slide freely along the longitudinal direction of the beam 1. The span of the frame can be adjusted freely. Be...

Abstract

The invention discloses a steam turbine rotor lifting tool which comprises a beam. A pair of lower hanging brackets are hung on the beam and symmetrically arranged corresponding to the gravity line ofthe beam; the lower hanging bracket is provided with a lower catenary wire used for hanging a steam turbine rotor; the part of the gravity line of the beam on the upper surface of the bream is provided with a hanger used for being hooked by the hook of a traveling crane; the lower hanging bracket is movably connected with the beam; and the span between the two hanging brackets can be freely adjusted. The steam turbine rotor lifting tool is applicable to lifting the rotors matched with various models ranging from small steam turbine of water-feeding pumps of a plurality of thousands of kilowatt to high-power steam turbines of one million kilowatts. The steam turbine rotor lifting tool can be used for improving the production efficiency by not repeatedly replacing the rotor lifting tools during the process of producing and manufacturing the steam turbines, thus saving the costs of labor force and resources for processing and manufacturing the steam turbine rotors. The steam turbine rotor is an important technical progress and has very high practical value.

Description

technical field [0001] The invention relates to a hoisting sling, in particular to a steam turbine rotor lifting tool used in a steam turbine manufacturing workshop, which is suitable for lifting steam turbine rotors of different models and specifications. Background technique [0002] During the steam turbine manufacturing process, the steam turbine rotor needs to be lifted according to the processing and assembly requirements. The steam turbine rotor is a large workpiece, and special lifting tools must be used to ensure the safety of the workpiece and people. The lifting tool is mainly composed of a beam and a pair of hangers suspended on the beam. The slings of the two hangers are respectively hung on the journals at both ends of the rotor, and the driving hook is hung on the center of gravity of the beam. When lifting, keep the balance of the beam to prevent If the workpiece overturns, keep the sling vertical to prevent it from scratching the blade. [0003] Existing h...
