[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 2 ,Figure 3 and Figure 4 The figure shows a device for preventing elastic deformation of a thrust bearing seat in a horizontal generator unit, including an internally threaded sleeve 1 and a tightening structure 2 at both ends. There are three internally threaded sleeves 1, which are evenly distributed in a fan-shaped arc. The tightening structure 2 includes a first screw 201 and a second screw 202. The first screw 201 and the second screw 202 are threaded to both ends of the internally threaded sleeve 1. The other ends of the first screw 201 and the second screw 202 are respectively welded to fixed lifting lugs 204. The threads of the first screw 201 and the second screw 202 are opposite in direction. Tightening nuts 203 are threaded to both the first screw 201 and the second screw 202. One of the fixed lifting lugs 204 is equipped with a fan-shaped wall steel plate 4, and the other fixed lifting lug 204 is equipped with a connecting structure 3.

[0019] It is worth noting that three evenly distributed fan-shaped internal threaded sleeves 1 are placed at appropriate positions on the thrust bearing housing. Then, a first screw 201 and a second screw 202 are threaded to both ends of each internal threaded sleeve 1. Fixing lugs 204 are welded to the other ends of the first screw 201 and the second screw 202 for subsequent connection and fixation. A fan-shaped wall steel plate 4 is installed on one of the fixing lugs 204 to provide additional support and stability. A connecting structure 3 is installed in the area of ​​the other fixing lug 204 to fix the entire thrust bearing housing, thus securing the entire horizontal machine... The reinforcement of the unit bearing housing reduces longitudinal displacement. Furthermore, by adjusting the position of the tightening nut 203, the tightening degree of the first screw 201 and the second screw 202 can be controlled, ensuring the stability of the thrust bearing housing. In addition, the design of the fan-shaped, evenly distributed internal thread sleeve 1 not only enhances the structural strength of the entire device but also effectively distributes stress, preventing deformation caused by excessive local stress. The design of the connecting structure 3 also fully considers actual installation requirements, ensuring that the thrust bearing housing can be firmly fixed in the predetermined position, further improving the safety and stability of the unit's operation.

[0020] Please see Figure 1 , Figure 2 and Figure 3The connecting structure 3 includes a reinforcing steel plate 301 and a clamping plate 303. Reinforcing steel plates 301 are installed on both sides of the clamping plate 303, and a welding protrusion 304 is welded to the bottom of the clamping plate 303. Notably, the welding protrusion 304 is welded to the outside of the thrust bearing housing. The combined design of the reinforcing steel plate 301 and the clamping plate 303 allows the welding protrusion 304 to be positioned and inserted into the two reinforcing steel plates 301 for welding, making the bearing housing connection point area more robust. The welding protrusion 304, acting as a connecting bridge, is welded to the outside of the thrust bearing housing, ensuring the accuracy and stability of the connection. The combination of the reinforcing steel plate 301 and the clamping plate 303 acts as a sturdy barrier, protecting the stability of the entire connecting structure 3. This design not only improves the load-bearing capacity of the device but also effectively prevents elastic deformation caused by external forces, further ensuring the safe and stable operation of the horizontal unit.

[0021] Please refer to Figure 1 and Figure 2 The front end face of the fan-shaped wall steel plate 4 is welded with an installation component 402 equal in number to the internal threaded sleeve 1. The fan-shaped wall steel plate 4 has several evenly arranged installation holes 401. The fan-shaped wall steel plate 4 is made of arc-shaped steel plate and fixed by multiple chemical bolts to ensure tensile strength greater than 80t and high vibration resistance.

[0022] See Figure 1 , Figure 2 and Figure 4 The reinforcing steel plate 301, clamping plate 303, and mounting component 402 are all equipped with insertion holes 207, each containing a connecting pin 205. The reinforcing steel plate 301, clamping plate 303, and mounting component 402 are all connected to adjacent fixed lifting lugs 204 via connecting pins 205. The connection method uses connecting pins 205 for fixing, ensuring easy disassembly and not affecting on-site equipment maintenance. The design of connecting pins 205 not only enhances the connection strength of the structure but also makes the connection between various components more flexible. When needed, workers can easily disassemble components by pulling out the connecting pins 205 for necessary maintenance or replacement, improving maintenance efficiency. Simultaneously, the insertion holes 207 ensure that the connecting pins 205 can be accurately and securely inserted. Tightening the nuts 203 secures the inserted connecting pins 205, avoiding safety hazards caused by unstable connections.

[0023] See Figure 4 One end of the connecting pin 205 is fixedly provided with a limiting rod 206, which provides a force point for removing the connecting pin 205, making it easy to pull out the connecting pin 205.

[0024] See Figure 2 and Figure 3The two reinforcing steel plates 301 and the clamping plate 303 are connected and installed by bolts 302 and corresponding mounting nuts 306. The top of both the reinforcing steel plates 301 and the clamping plate 303 are provided with buckle holes 305. The buckle holes 305 are designed to cooperate with other fasteners or hoisting equipment so that the entire thrust bearing seat device can be easily fixed or hoisted during installation or disassembly. At the same time, the connection method of bolts 302 and mounting nuts 306 further enhances the connection strength between the reinforcing steel plates 301 and the clamping plate 303, making the entire device more stable and reliable.

[0025] Working principle: Three evenly distributed fan-shaped internal threaded sleeves 1 are placed at appropriate positions on the thrust bearing housing. Then, a first screw 201 and a second screw 202 are threaded to both ends of each internal threaded sleeve 1. Fixing lugs 204 are welded to the other ends of the first screw 201 and the second screw 202 respectively for subsequent connection and fixation. A fan-shaped wall steel plate 4 is installed on one of the fixing lugs 204 to provide additional support and stability. In the area of ​​the other fixing lug 204, a connecting structure 3 is installed. This structure includes a reinforcing steel plate 301 and a clamping plate 303. The welding protrusion 304 is welded to the outside of the thrust bearing housing bearing box to ensure the accuracy and stability of the connection. In addition, the reinforcing steel plate 301, the clamping plate 303 and the mounting part 402 are all provided with insertion holes 207 and connected to the adjacent fixing lugs 204 through connecting pins 205. This connection method not only enhances the connection strength of the structure, but also makes the connection between the various components more flexible, and facilitates disassembly and maintenance.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
