[0002] As a consumable part, the rotor of a large steam turbine mechanical equipment usually needs to be kept in stock to prevent timely replacement when the equipment fails. The packaging of the steam turbine rotor must be able to adapt to long-distance transportation and multiple loading and unloading to ensure that the product arrives safely at the destination. The packaging form of the steam turbine rotor should be adapted to its structural characteristics, importance, precision, transportation conditions and weight. At the same time, the packaging is required to be economical, practical and beautiful.

[0003] At present, most steam turbine rotors are packed in wooden boxes, especially for export products. At present, in the use of wooden boxes for transportation, a few foams are generally stuffed in the four corners of the box body, so that the installation is not tight and not firm, easy to loosen, and often damaged during transportation, causing certain economic losses to enterprises or customers. The patent application with the authorization announcement number CN202244672U discloses a new vacuum packaging structure for large steam turbine generator rotors, which is characterized by: including a composite aluminum foil material for packaging the rotor, a square wood for fixing the rotor, and a stud screw for fixing the square wood. The concave section of the square wood is semicircular, and a buffer material is provided between the square wood and the composite aluminum foil material. However, with the development of the economy, the demand for wood has increased significantly, the contradiction between the supply and demand of wood has gradually become prominent, and the wood used for steam turbine rotor packaging cannot be reused, which leads to an increase in packaging costs year by year, increasing the production cost of steam turbines. Utility Model Content

[0004] In order to overcome the defects of the prior art that wood packaging cannot be reused and has high cost, the utility model provides a packaging bracket for a steam turbine rotor.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a packaging bracket for a steam turbine rotor, comprising a base and an upper bracket, wherein a left bracket and a right bracket for carrying the steam turbine rotor are respectively provided at two ends of the base, a left end cover is detachably connected to the left bracket, and a right end cover is detachably connected to the right bracket, a plurality of legs are provided on the base between the left bracket and the right bracket, and the legs are arranged on the legs, and lifting ears are provided on the front and rear sides of the left bracket and the right bracket.

[0006] As a further improvement of the utility model, the left bracket and the left end cover, and the right bracket and the right end cover are all detachably connected by bolts.

[0007] As a further improvement of the utility model, the supporting legs are connected to the left bracket and the right bracket through a connecting rod.

[0008] As a further improvement of the utility model, the upper bracket is a cage-shaped cover.

[0009] As a further improvement of the utility model, a foot seat is provided at the bottom of the base.

[0010] As a further improvement of the utility model, an anti-slip pad is provided at the lower part of the foot seat.

[0011] Compared with the prior art, the utility model has the following beneficial effects: in this solution, the left bracket and the right bracket are welded to the base, and the left bracket and the right bracket are on the same horizontal line, and are used to support the turbine rotor. The left bracket and the right bracket are provided with lifting ears on both the front and rear sides for easy lifting; the upper bracket has the function of protecting the turbine rotor and supporting the covering cloth; after the lifting is completed, the left end cover and the right end cover are installed, and the left end cover and the right end cover respectively protect the left and right ends of the rotor, and the covering cloth has the function of rain and sun protection, simple structure, high safety, easy disassembly and installation as a whole, and can be reused to reduce costs.
