Abstract
Description
Technical Field
[0001] The utility model relates to a rotor bracket. Background Art
[0002] The rotor bracket is used to hold up large and medium-sized rotors during maintenance in the petrochemical, electric power, heating, shipbuilding and other industries. The rotor bracket consists of two rotor brackets, the active end bracket and the driven end bracket. After the equipment is dismantled and the rotor is lifted out, the shaft necks at both ends of the rotor are placed on the rotor bracket. However, due to the constraints of on-site conditions, large equipment manufacturers such as steam turbine generator sets will be equipped with special rotor brackets. However, due to cost considerations, special rotor holding equipment can only serve as a support and cannot meet the actual needs of the site. For example, when the equipment maintenance time is relatively long, it is necessary to regularly turn the rotor to ensure that the rotor is not subjected to gravity bending. At the same time, when the rotor is turned, the rotor shaft neck position must be lubricated to a certain extent; another situation is that special generator or motor rotors need to prevent static electricity, so it is necessary to give special consideration to the material of the rotor holding equipment support contact position. Summary of the invention
[0003] The utility model aims to provide a rotor bracket, which improves the maintenance efficiency, reduces the risk of personnel operation, shortens the maintenance time, and reduces the occurrence of self-gravity bending of the rotor due to the inability to regularly turn the rotor. The technical scheme of the utility model is: a rotor bracket, the bracket rotor (1) is composed of a fixing bolt (2), a bearing baffle (3), a lubricating oil chamber (4), a copper sleeve (5), a roller pressing block (6), a roller rotor (7), a lifting lug (8), an adjusting pad (9), an oil drain port (10), a roller inner sleeve (11), a bearing (12), a bolt hole (13), a roller body (14), and a rib plate (15), the bearing (12) is sleeved on the roller rotor (7), each roller body (14) is fixed to the outside of the lubricating oil chamber (4) by the roller pressing block (6), two lifting lugs (8) are symmetrically installed on both sides of two bracket lubricating oil chambers (4), two oil drain ports (10) are installed at the bottom of the lubricating oil chamber (4), the rib plate (15) is installed and fixed inside the lubricating oil chamber (4), the bottom plate of the lubricating oil chamber (4) is fixedly connected to the bracket body (1), and the oil drain port (10) is installed below the lubricating oil chamber (4).
[0004] A lubricating oil chamber (4) is installed on the rotor bracket (1).
[0005] The copper sleeve (5) can be made of a high-strength nylon sleeve made of antistatic material.
[0006] An adjusting pad (9) is installed at the lower part of the roller rotor (7).
[0007] An oil drain port (10) is installed below the lubricating oil chamber (4) of the rotor bracket (1).
[0008] The working principle of this utility model:
[0009] The utility model symmetrically mounts two roller bodies (14) on a rotor bracket (1), and an adjusting pad (9) is mounted on the lower part of the roller rotor (7) to adjust the height of the roller body (14) according to rotors of different sizes, so as to ensure that the rotor is in a stable state when placed on the rotor bracket. The roller body (14) is tightly fixed to the outer side of the lubricating oil chamber (4) by a roller pressing block (6). A certain amount of lubricating oil is injected into the lubricating oil chamber (4), and the lubricating oil liquid level can submerge the copper sleeve (5) at the lower part of the roller body (14), so that when the roller body (14) rotates, the surface of the copper sleeve (5) can be stained with lubricating oil, and the lubricating oil can fully lubricate the shaft diameter of the rotor, so as to protect the shaft diameter of the rotor when the rotor rotates. After the rotor bracket is overhauled and used, the lubricating oil in the lubricating oil chamber (4) is drained through the oil drain port (10). The rib plate (15) is welded to the lubricating oil chamber (4) to play a role of reinforcement and support, and is hung on the lifting lug (8) by a crane or lifting equipment for movement and transportation.
[0010] Technical effects of this utility model:
[0011] The utility model designs a bracket capable of bearing and supporting a rotor. By installing and arranging rollers capable of smoothly rotating on the bracket body, after the lubricating oil chamber is filled with oil, the lubricating oil is in full contact with the rollers. When the rotor is rotated, the shaft diameter of the rotor can be fully lubricated, thereby protecting the shaft diameter of the rotor when the rotor rotates. After the rotor bracket is overhauled and used, the lubricating oil in the lubricating oil chamber (4) is drained through the oil drain port (10). BRIEF DESCRIPTION OF THE DRAWINGS
