[0001] The invention relates to the technical field of bases, in particular to a steam turbine base. 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 is then sprayed onto the blades, causing the rotor equipped with the blade rows to rotate and perform work externally. The emergence of steam turbines has promoted the development of the electric power industry. Steam turbines are widely used in various sectors of the social economy. 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. With the continuous development of science and technology, the single-unit power of steam turbines is also increasing. During the use of a steam turbine, the position of the steam turbine may need to be changed due to changes in the site of use.

After moving to a suitable location, the lower base 1 is supported by the hydraulic cylinder 30 in the above manner, and the driving motor 15 is started to make the rotating frame 5 rotate in the opposite direction and enter the interior of the protective cover 32 for reset, and then the hydraulic cylinder 30 is started to shrink so that the plurality of supporting bottom plates 31 support the bottom of the lower base 1.

[0027] like Figure 2 and Figure 3 As shown, a fixing frame 22 is fixedly installed on one side of the inner part of the first fixing groove 6, and an electric push-pull rod 23 is fixedly sleeved inside the fixing frame 22. The electric push-pull rod 23 is electrically connected to the PLC controller, and a supporting hole 25 is provided on one side of the fixing frame 22. A third limiting column 24 is movably sleeved on the inner circular wall of the supporting hole 25.

Through the provided electric push-pull rod 23, when the moving wheel 3 is in an upright state, in order to prevent the moving wheel 3 from rotating sideways, the electric push-pull rod 23 is started to push the third limit column 24 into the interior of the limit groove 29 and then limit the rotating frame 5, so that the rotating frame 5 will no longer rotate, thereby ensuring the movement effect.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a plurality of third fixing holes 33 are opened on the top surface of the lower base 1, a hydraulic cylinder 30 is fixedly sleeved on the inner circular wall surface of the third fixing hole 33, a plurality of supporting base plates 31 are fixedly installed on the bottom surface of the lower base 1, a protective cover 32 is fixedly sleeved inside the first fixing groove 6, and the outer circular wall surface of the second limiting column 19 is coated with grease.

[0030] It should be noted that when the present invention is in use, through the lower base 1, when the user needs to move the upper base 2 (the upper base 2 is the same as the upper base in the reference document), the hydraulic cylinder 30 is started at this time to extend the telescopic shaft to lift the lower base 1, and the plurality of supporting base plates 31 no longer support the lower base 1, thereby starting the drive motor 15 to drive the connecting column 20 to rotate and drive the two face gears 16 to rotate, and through the support plate 18, the support plate 18 is in the groove on the outer circumferential wall of the second limiting column 19 to support and limit the second limiting column 19, and the rotating face gear 16 drives the second meshing face gear 16 to rotate. The rotation of the second limit column 19 drives the universal joint 17 and the threaded column 12 to rotate, and the threaded column 12 and the bent threaded tube 11 convert the rotational motion into a linear motion, so that the length of the bent threaded tube 11 and the threaded column 12 becomes longer, so that the bent threaded tube 11 pushes the connecting ring 10 to drive the fixed column 8 and the rotating frame 5 to rotate with the first fixed plate 4 as the center of the circle, so that the rotation of the rotating frame 5 drives the first limit column 7 and the moving wheel 3 to flip so that the moving wheel 3 is in an upright state. At the same time, the electric push-pull rod 23 is started so that the telescopic shaft pulls the electric push-pull rod 23 into the inside of the support hole 25. Then, when the rotating frame 5 is erected, the electric push-pull rod 23 is started so that the third limit column 24 moves The lower base 1 is supported by the movable wheels 3, and the movable wheels 3 can be rotated by the first limiting column 7 during movement, so that the lower base 1 is turned, thereby facilitating the user to move the lower base 1. After moving to a suitable location, the lower base 1 is supported by the hydraulic cylinder 30 in the above manner, and the driving motor is started. 15 makes the rotating frame 5 rotate in the opposite direction and enter the interior of the protective cover 32 to reset, and then starts the hydraulic cylinder 30 to contract so that the multiple supporting base plates 31 support the bottom of the lower base 1, thereby achieving the effect of moving the lower base 1, so that there is no need to manually operate the lifting and lowering of the moving wheels 3 to support the heavy lower base 1 for moving, which saves manpower, and the lubricating oil of the bearings of the moving wheels 3 will not be lost, avoiding affecting the movement of the upper base 2. At the same time, the side of the lower base 1 can be pushed to make the moving wheels 3 rotate slightly and then the lower base 1 can be turned, which is convenient for use, ensures the movement effect of the upper base 2, and is more practical.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
