Description

Technical Field

[0001] The utility model belongs to the technical field of steam turbines, in particular to a steam turbine base frame with a protection structure. Background Art

[0002] A steam turbine, also known as a steam turbine engine, is a rotary steam power device. High-temperature and high-pressure steam passes through a fixed nozzle to become an accelerated airflow and then is sprayed onto the blades, causing the rotor equipped with blade rows to rotate and perform work externally. Steam turbines are the main equipment in modern thermal power plants and are also used in the metallurgical industry, chemical industry, and ship power plants. The steam turbines in the prior art are huge in size, and maintenance personnel often need to climb to the top of the steam turbine during maintenance, which is very inconvenient. To address this problem, a mounting base for a gas plant steam turbine is provided.

[0003] Prior art, such as: CN216518174U A gas plant steam turbine mounting base, including a base, baffles are respectively arranged on the left and right sides of the top of the base, guide rods are respectively arranged on the front and rear ends of the inner sides of the two baffles, the outer walls of the two guide rods are respectively slidably sleeved with moving blocks, ladders are fixedly installed on the tops of the two moving blocks, sliding boxes are respectively arranged on the inner sides of the two moving blocks, and the inner cavities of the two sliding boxes are respectively provided with fixed components. The utility model relates to the technical field of power generation equipment, and solves the problem that the steam turbine is huge in size and maintenance personnel often need to climb to the top of the steam turbine during maintenance, which is very inconvenient during maintenance.

[0004] However, the above and other typical existing technologies still have certain problems when used:

[0005] 1.

[0006] 2. The steam turbine base frame of the patent does not have a device to fix the steam turbine so that it will not move. Although the steam turbine is huge, the center of gravity of the steam turbine is mostly upward, which will cause the steam turbine to move when heavy objects appear on the steam turbine, which is very dangerous.
