Description

A support assembly for disassembling and assembling generator sealing tile chambers Technical Field

[0001] This utility model relates to the field of generator disassembly and assembly tools, and in particular to a support assembly for disassembling and assembling generator sealing tile chambers. Background Technology

[0002] In modern power production, the generator sealing tile chamber is a key component that ensures the safe and stable operation of the generator. The quality and efficiency of its installation and disassembly directly affect the reliability and maintenance cycle of the unit.

[0003] In existing technology, due to the relative sliding between the lower bearing and the lower sealing tile chamber, the sealing tile chamber is usually disassembled and assembled using a special tool and a hand-operated hoist. Generally, the lower bearing must be removed first, followed by the lower sealing tile chamber. Due to the presence of the stator shaft support, to avoid interference, the lower bearing must be rotated upwards before disassembly. After the lower bearing is disassembled, the lower sealing tile chamber is rotated upwards. At this point, the lower sealing tile chamber, without the inner ring support, lacks effective restraint and is very prone to tilting under its own weight and external operating forces. Once tilting occurs, the lower sealing tile chamber will inevitably scrape against the generator rotor shaft diameter or sealing strip, directly causing scratches or damage to the surface of the generator rotor shaft diameter, affecting its operational stability and service life; or damaging the generator's sealing performance, leading to safety hazards such as hydrogen leakage and oil leakage.

[0004] Therefore, there is an urgent need for a support assembly for the disassembly and assembly of generator sealing tile chambers to avoid the problem of the lower sealing tile chambers easily tipping over during the disassembly and assembly process. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a support assembly for disassembling and assembling generator sealing tile chambers, which solves the technical problem that the lower half of the sealing tile chamber is prone to tipping over during disassembly and assembly.

One end face of the support assembly is an arc-shaped surface, which can be slidably connected to the outer periphery of the stator shaft. When the support assembly is connected to the lower half sealing tile chamber, the arc-shaped surface abuts against the outer periphery of the stator shaft to support the lower half sealing tile chamber on the stator shaft.

[0010] Preferably, it includes a plate and a positioning block. The plate is detachably connected to the lower half-sealing tile chamber, and the arc-shaped surface is provided on the end face of the plate near the stator shaft. The positioning block is provided on the side of the plate near the lower half-sealing tile chamber, and the positioning block matches the groove of the lower half-sealing tile chamber.

[0011] Preferably, a first connecting hole is provided on the plate; the positioning block is detachably connected to the first connecting hole on the plate through a first connecting member.

[0017] (III) Beneficial Effects

[0018] The beneficial effects of this utility model are:

[0019] This utility model discloses a support assembly for disassembling and assembling generator sealing tile chambers. The support assembly is connected to the axial end face of the lower half of the sealing tile chamber. One end face of the support assembly is arc-shaped, which can slide onto the outer circumference of the stator shaft. When the support assembly is connected to the lower half of the sealing tile chamber, the arc-shaped surface abuts against the outer circumference of the stator shaft to support the lower half of the sealing tile chamber on the stator shaft, thus providing a reliable connection and support structure for the lower half of the sealing tile chamber, which has lost its inner ring support. Compared to the lack of effective restraint during the disassembly of the lower half of the sealing tile chamber in existing technologies, this support assembly, through its stable connection with the stator shaft after the lower half bearing is disassembled, effectively limits its tilting due to its own weight and external operating forces, fundamentally solving the problem of the lower half of the sealing tile chamber easily tipping over, and thus significantly improving the safety of generator sealing tile chamber disassembly and assembly operations.

[0020] Meanwhile, the design of the detachable connection between the support component and the lower semi-sealed tile chamber allows the support component to be quickly installed and separated from the lower semi-sealed tile chamber, making the operation simple and convenient and improving the efficiency of disassembly and assembly. In addition, the arc-shaped end face of the support component, which is adapted to the outer circumference of the stator shaft, makes it suitable for disassembly and assembly operations of generators of various specifications, with strong versatility, which helps to promote its application.

[0033] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] In this embodiment, the generator sealing tile chamber includes an upper half sealing tile chamber and a lower half sealing tile chamber 3 arranged vertically. During the disassembly and assembly of the sealing tile chamber, the upper half sealing tile chamber, the upper half bearing, the lower half bearing 2, and the lower half sealing tile chamber 3 are removed sequentially. Figure 1 shows a schematic diagram of the generator sealing tile chamber after the upper half bearing and the upper half sealing tile chamber have been removed. In practical applications, to prevent the stator shaft 4 from rotating, it needs to be supported by the stator shaft support seat 5.

[0035] As shown in Figures 2-4, this embodiment of the invention provides a support assembly 1 for disassembling and assembling generator sealing tile chambers. The support assembly 1 is detachably connected to the axial end face of the lower half sealing tile chamber 3. One end face of the support assembly 1 is an arc-shaped surface, which can slide on the outer periphery of the stator shaft 4. When the support assembly 1 is connected to the lower half sealing tile chamber 3, the arc-shaped surface abuts against the outer periphery of the stator shaft 4 to support the lower half sealing tile chamber 3 on the stator shaft 4, thereby providing a reliable connection and support structure for the lower half sealing tile chamber 3, which has lost its inner ring support. Compared with the lack of effective restraint during the disassembly of the lower half sealing tile chamber 3 in the prior art, this support assembly 1 can effectively limit the tilting caused by its own weight and external operating forces after the lower half bearing 2 is disassembled through a stable connection with the stator shaft 4, fundamentally solving the problem of the lower half sealing tile chamber 3 being prone to tipping over, and thus greatly improving the safety of generator sealing tile chamber disassembly and assembly operations.

[0036] Meanwhile, the design of the detachable connection between the support component 1 and the lower semi-sealed tile chamber 3 allows the support component 1 to be quickly installed and separated from the lower semi-sealed tile chamber 3, making the operation simple and convenient and improving the efficiency of disassembly and assembly. In addition, the arc-shaped end face of the support component 1, which is adapted to the outer periphery of the stator shaft 4, makes it suitable for disassembly and assembly operations of generators of various specifications, with strong versatility, which helps to promote its application.

[0037] As shown in Figures 5 and 6, the support assembly 1 includes a plate 11 and a positioning block 12. The plate 11 is detachably connected to the lower semi-sealing chamber 3. An arc-shaped surface is located on the end face of the plate 11 near the stator shaft 4. The positioning block 12 is located on the side of the plate 11 near the lower semi-sealing chamber 3, and it matches the groove of the lower semi-sealing chamber 3. The positioning block 12 enhances the stability and accuracy of the connection between the support assembly 1 and the lower semi-sealing chamber 3. Through the cooperation of the positioning block 12 and the groove, the positioning and installation of the support assembly 1 and the lower semi-sealing chamber 3 can be achieved quickly and accurately, avoiding misalignment problems that may occur during the connection process. At the same time, it also helps to improve disassembly and assembly efficiency, reduce installation and debugging time, and make the entire disassembly and assembly operation more convenient and efficient.

[0038] To facilitate the installation and removal of the positioning block 12, a first connecting hole 111 is provided on the plate 11. The positioning block 12 is detachably connected to the first connecting hole 111 on the plate 11 via a first connecting piece 13. When dealing with lower semi-sealed tile chambers 3 of different specifications or structures, the positioning block 12 can be replaced or adjusted according to actual needs, enhancing the adaptability of the support assembly 1. At the same time, the detachable connection method facilitates the maintenance and component replacement of the support assembly 1. When the positioning block 12 is worn or damaged, it can be quickly repaired or replaced, reducing the maintenance cost of the support assembly 1 and extending its service life.

[0039] To reduce friction between the support assembly 1 and the stator shaft 4 and avoid damage to the stator shaft 4, the support assembly 1 also includes multiple sets of roller assemblies 15. The multiple sets of roller assemblies 15 are spaced apart on the side of the plate 11 near the stator shaft 4, and the rolling surfaces of the multiple sets of roller assemblies 15 are in rolling contact with the stator shaft 4. The rolling surfaces of the multiple sets of roller assemblies 15 form an arc-shaped surface, thereby converting the sliding friction between the arc-shaped surface and the stator shaft 4 into rolling friction. This greatly reduces the friction during disassembly and assembly, avoids damage to the stator shaft 4, and makes the lower semi-sealing chamber 3 move more smoothly, reducing the need for external operating force.

[0040] As shown in Figures 5 and 6, each roller assembly 15 includes a connecting shaft 151 and two rollers 152. The connecting shaft 151 is mounted on the plate 11, and the two rollers 152 are respectively located on both sides of the connecting shaft 151. The rolling surfaces of the rollers 152 abut against the outer periphery of the stator shaft 4. The double-sided roller design of the roller assembly 15 further enhances the support and guidance for the lower sealing tile chamber 3, enabling the sealing tile chamber to maintain balance during movement along the stator shaft 4 and preventing displacement or tilting due to uneven force on one side. At the same time, the double-sided rollers 152 can contact the stator shaft 4 more stably, ensuring the reliability of the rolling connection and effectively reducing the possibility of jamming or detachment of the roller assembly 15 during use, thus ensuring smooth disassembly and assembly operations.

[0041] The roller 152 is made of rubber. Rubber has good elasticity and wear resistance. On the one hand, it can effectively buffer the impact force caused by collision or vibration during disassembly and assembly, reduce damage to the surface of the stator shaft 4, and protect the integrity of the stator shaft 4. On the other hand, the rubber roller 152 has appropriate friction with the stator shaft 4, which can ensure that the roller 152 rolls stably on the stator shaft 4, and prevent the sealing chamber from moving out of control due to insufficient friction, thereby further improving the safety and reliability of disassembly and assembly operations.

[0042] As shown in Figure 6, the plate 11 has at least two second connecting holes 112, which are spaced apart. The plate 11 is detachably connected to the lower semi-sealing tile chamber 3 via a second connector 14 passing through the second connecting holes 112. The second connecting holes 112 are elongated. The multiple second connecting holes 112 increase the connection points between the support assembly 1 and the lower semi-sealing tile chamber 3, making the connection more secure and stable. The elongated design allows the second connector 14 some adjustment space within the hole, enabling it to better accommodate minor deviations in the mounting hole position of the sealing tile chamber when connected to the lower semi-sealing tile chamber 3, reducing installation difficulty and improving the accuracy and convenience of the connection.

[0043] It should be noted that in this embodiment, the first connector 13 and the second connector 14 are connecting bolts.
