Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steam turbine pedestal beam reinforcement, in particular to a reinforcement device for a steam turbine pedestal beam of a thermal power plant. Background Technique
[0002] The steam turbine pedestal beam of a thermal power plant is composed of two support columns and a base beam. A steam turbine is the abbreviation of a steam engine and a steam turbine. After long-term use of the steam turbine in a thermal power plant, high-frequency vibration will occur during the rotation of the steam turbine impeller. This high-frequency vibration will drive the steam turbine pedestal beam to produce a resonance effect. If the steam turbine pedestal beam is subjected to such high-frequency vibration for a long time, the support columns and the base beam in the steam turbine pedestal beam will become loose, and then it is necessary to reinforce the steam turbine pedestal beam.
[0003] The common reinforcement method is to nail the support columns and the base beam for reinforcement. However, nailing reinforcement will cause different degrees of damage to the steam turbine pedestal beam, destroy the original stress structure, and cause the steam turbine pedestal beam to deform and collapse. Therefore, those skilled in the art provide a reinforcement device for a steam turbine pedestal beam of a thermal power plant to solve the problems raised in the above background technique.

[0008] Preferably, one end of the third link is connected to the first link, and the other end of the third link is connected to the second link. By rotating the bidirectional screw on the two third links, the two third links contract relative to each other, thereby stretching the first link and the second link on the two columns to a tightened state. When the first link and the second link are tightened, the frictional force between the bottom clamping fixture, the top clamping fixture and the column increases, and the connection becomes tighter.
[0009] Preferably, the upper side of the supporting plate is in supporting contact with the base beam, and the supporting plate is concave to be in supporting contact with the base beam, which can effectively support and reinforce the connection between the column and the base beam.
[0010] Preferably, the inner walls of both sides of the supporting plate are threadedly connected with hexagon socket head cap screws. A rubber pad is installed at one end of the hexagon socket head cap screw facing the base beam. By rotating the hexagon socket head cap screw, the end with the rubber pad can be squeezed into contact with the base beam, so that the supporting plate can be squeezed and fixed to the base beam.
[0011] (III) Advantageous Effects

At this time, the frictional force between the bottom clamping fixture, the top clamping fixture and the column increases, and the connection becomes tighter, and the supporting plate on the top clamping fixture supports more stably. In this structure, there is no need to drill holes and drive nails in the column and the base beam, which will not damage the original stress structure of the base beam, and avoid the problems of deformation and collapse of the base beam.

[0019] The present invention provides a technical solution, a reinforcement device for the steam turbine base beam 1 of a thermal power plant.

[0020] Please refer to Figure 1 , Figure 3 , the upper side of the supporting plate 6 is in supporting contact with the base beam 1, and the supporting plate 6 is concave to make supporting contact with the base beam 1, which can effectively support and reinforce the connection between the column 2 and the base beam 1. Internal hexagonal bolts 8 are threadedly connected to both side walls of the supporting plate 6, and a rubber pad 9 is installed at one end of the internal hexagonal bolt 8 facing the base beam 1. By rotating the internal hexagonal bolt 8, the end with the rubber pad 9 can be pressed against the base beam 1, so that the supporting plate 6 can be pressed and fixed to the base beam 1. One end of the third connecting rod 12 is connected to the first connecting rod 10, and the other end of the third connecting rod 12 is connected to the second connecting rod 11. By rotating the double-threaded screw 13 on the two third connecting rods 12, the two third connecting rods 12 are relatively contracted, so that the first connecting rod 10 and the second connecting rod 11 on the two columns 2 are stretched to a taut state. When the first connecting rod 10 and the second connecting rod 11 are taut, the frictional force between the bottom clamping and fixing part 3 and the top clamping and fixing part 5 and the column 2 increases, and the connection is tighter, so that the supporting plate 6 on the top clamping and fixing part 5 supports more stably.
[0021] In this utility model, a bottom clamping and fixing member 3 and a top clamping and fixing member 5 are respectively installed at the upper and lower ends of the column 2. Both the bottom clamping and fixing member 3 and the top clamping and fixing member 5 are composed of a pressing plate and a bolt. The two pressing plates are clamped on the column 2 by the bolt.
[0022] A supporting plate 6 is installed on the top clamping and fixing member 5. The supporting plate 6 is concave and makes a supporting contact with the base beam 1. Inner hexagon bolts 8 are threadedly connected to the two side walls of the supporting plate 6. By rotating the inner hexagon bolts 8, the end with the rubber pad 9 can be pressed against the base beam 1, so that the supporting plate 6 can be pressed and fixed to the base beam 1. And the included angle between the top clamping and fixing member 5 and the supporting plate 6 is ninety degrees. With the cooperation of the reinforcing plate 7, the connection between the column 2 and the base beam 1 can be effectively supported and strengthened, avoiding deformation at the connection between the column 2 and the base beam 1.
[0023] A connecting plate 4 is installed on one side of the bottom clamping and fixing member 3. A first connecting rod 10 is rotatably connected to the connecting plate 4. A second connecting rod 11 is rotatably connected to the reinforcing plate 7 on one side of the top clamping and fixing member 5. A third connecting rod 12 is arranged between the second connecting rod 11 and the first connecting rod 10. The third connecting rod 12 connects the first connecting rod 10 and the second connecting rod 11. Then, by rotating the bidirectional screw 13 on the two third connecting rods 12, the two third connecting rods 12 are relatively contracted, so that the first connecting rod 10 and the second connecting rod 11 on the two columns 2 are stretched to a tightened state. At this time, under the fastening of the bidirectional screw 13, with the tightening of the first connecting rod 10 and the second connecting rod 11, the frictional force between the bottom clamping and fixing member 3 and the top clamping and fixing member 5 and the column 2 increases, and the connection is tighter. And the supporting plate 6 on the top clamping and fixing member 5 is supported more stably.
