Abstract
The utility model relates to a hoist, in particular to an equalizing beam for hoisting a rotor. The equalizing beam, which is hung on the hook of the hoist through a steel rope, comprises a crossbeam, both ends of which are respectively provided with a pair of lifting lugs, four lifting lugs in total, two of the lifting lugs are connected with the front and the rear bearing positions of a rotary shaft through steel ropes, and the other two lifting lugs are connected with the hook of the hoist through a steel rope. The utility model can prevent the airtight strips of the rotor from being injured, and has the advantages of simple structure and convenient use.
Description
Technical field
The utility model relates to overhead hoist, relates in particular to the rotor overhead hoist.
Background technology
The following method of the former employing of TRT turbine rotor lifts, steel rope is connected the axle journal place of rotor front and back bearings, arrive the lifting mode like this, can run into following two problems: 1, can produce certain included angle between steel rope and the rotor step, after steel rope is stressed, the step limit of rotor forms extruding to steel rope easily, can cause the damage of steel rope, reduces its service life; 2, steel rope is hoisting or the falling process, accidentally, is easy to make that the sealing gland sheet of wire rope hanging place rotor sustains damage.
But because rotor is accurate, visual plant, in the lifting work of rotor above-mentioned accident can not take place.
Summary of the invention
The utility model is intended to solve the problems referred to above in the existing rotor handling, and a kind of equalizing bar that is used to lift rotor is provided.The utility model guarantees that rotor sealing gland sheet is injury-free, and the utility model is simple in structure, easy to use.
The utility model is achieved in that
A kind of equalizing bar that is used to lift rotor, it is suspended on the suspension hook of loop wheel machine by steel rope, it comprises: a crossbeam, the two ends of described crossbeam respectively carry a pair of hanger, amount to four, wherein two are utilized steel rope to be connected former and later two position of bearingss of rotating shaft, and two hangers utilize steel rope to be connected with the loop wheel machine suspension hook in addition.
The described equalizing bar that is used to lift rotor, described four hangers are the steel plate that an end has an aperture, and are welded to connect on crossbeam with the other end, and the hanger of each side is respectively in the upper surface and the lower surface of crossbeam.
The special equalizing bar of making of the utility model utilization comes the handling rotor, guarantees that rotor sealing gland sheet is injury-free, and the utility model is simple in structure, easy to use.
Description of drawings
Below, further specify the utility model in conjunction with the accompanying drawings:
Fig. 1 is for utilizing the utility model handling view;
Fig. 2 is the utility model scheme drawing.
The specific embodiment
As depicted in figs. 1 and 2: a kind of equalizing bar that is used to lift rotor, it is suspended on the suspension hook 2 of loop wheel machine by steel rope 1, it comprises: a crossbeam 3, the two ends of described crossbeam 3 respectively carry a pair of hanger 4, amount to four, two hangers 4 wherein utilize steel rope 1 to be connected rotating shaft 5 former and later two position of bearingss, and two hangers 4 utilize steel rope 1 to be connected with loop wheel machine suspension hook 2 in addition.
Described four hangers 4 are the steel plate that an end has an aperture, and are welded to connect on crossbeam 3 with the other end, and the hanger 4 of each side is respectively in the upper surface and the lower surface of crossbeam 3.
Claims (2)
