[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] like Figures 1 to 5 As shown, a heavy-duty long-axis component stabilization device includes:

[0036] The support assembly includes two support rollers 6, whose axes are parallel to the axis of the long shaft component 7, with the distance between the two support rollers 6 being less than the diameter of the long shaft component 7. The support rollers 6 are rotatably connected to the lifting plate 1. The base 2 has a through hole 1, and the lifting plate 1 has a through hole 2. A guide rod 19 extends through through holes 1 and 2, respectively. A compression spring 18 is provided on the outside of the guide rod 9, located between the base 2 and the lifting plate 1. A damper is provided between the compression spring 8 and the base 2. There are two support assemblies. There are four guide rods 19, located at the four corners of the lifting plate 1.

[0037] A mounting plate 101 is fixed on the lifting plate 1, and the end of the mounting plate 101 away from the axis of the long-axis component 7 is tilted upward; the support roller 6 is rotatably connected to the mounting seat 5, and the mounting seat 5 is connected to the mounting plate 101 by a bolt 103. The mounting plate 101 is tilted so that the force on the vertical plate 501 is perpendicular to the vertical plate 501, thereby preventing the vertical plate 501 from deforming.

[0038] The mounting base 5 includes a base plate 502 and two vertical plates 501 fixed on the base plate 502. The upper end of the vertical plate 501 is provided with a mounting groove 503. The support roller 6 is rotatably connected to the mounting shaft 505 through a bearing 504. Both ends of the mounting shaft 505 are installed in the mounting groove 503. Both ends of the mounting shaft 505 are provided with external threads. Both ends of the mounting shaft 505 are threadedly connected with locking nuts. The locking nuts lock the mounting shaft 505 and the vertical plates 501. The base plate 502 is connected to the mounting plate 101 through bolts 103.

[0039] A limiting boss 102 for limiting the mounting seat 5 is fixedly provided at one end of the mounting plate 101 adjacent to the axis of the long-axis component 7. The limiting boss 102 plays a positioning role for the base plate 502 of the mounting seat 5. When the mounting seat 5 is installed after maintenance, it is convenient to install the mounting seat 5 to the specified position, thereby improving the installation efficiency, reducing the load on the bolt 103, and increasing the service life of the bolt 103.

[0040] Guide rod 1 (9) has external threads at both ends. Limit nuts are threaded onto both ends of guide rod 1 (9), one of which presses against the upper end of lift plate 1, while the other locknut presses against the lower end of base 2. Guide tube 10, corresponding to guide rod 1 (9), is fixed to both lift plate 1 and base 2. Guide rod 1 (9) is mounted inside guide tube 10. Guide rod 1 (9) is positioned vertically. The arrangement of guide rod 1 (9) and guide tube 10 guides the vertical movement of lift plate 1 and positions the compression spring, ensuring more stable movement of lift plate 1. The outer diameter of guide rod 9 matches the inner diameter of guide tube 10.

[0041] Rollers 201 are fixed to the lower end of base 2, movably connected to track 3 via these rollers. Track 3's length is perpendicular to the axis of heavy-duty, long-axis components 7. Track 3 and stopper 4 are both fixedly connected to the ground. Four rollers 201 are located at the four corners of base 2, with two rollers 201 on each side corresponding to one track 3.

[0042] Limiting seats 4 are provided at both ends of the track 3. A vertical plate 202 is fixed to the base 2. Vertical plate 202 has a through hole 3. The limiting seat 4 has a through hole 4 corresponding to through hole 3. A guide rod 2 12 passes through through holes 3 and 4 and is arranged along the length of the track 3. A compression spring 2 11 is provided between the vertical plate 202 and the limiting seat 4. The compression spring 2 11 is located outside the guide rod 2 12. Both ends of the guide rod 2 12 have external threads, and connecting nuts are threadedly connected to the ends of the guide rod 2 12. The connecting nuts press against the end face of the limiting seat 4 facing away from the compression spring 2 11. A guide tube 2 13 is fixed to the vertical plate 202, corresponding to through hole 3. The guide rod 2 12 is mounted inside the guide tube 2 13. The guide rod 2 12 serves as a guide during the movement of the base 2, while the limiting seat 4 serves as a limiter. A damper is provided between the compression spring 2 11 and the limiting seat 4.

[0043] Working process:

[0044] Action implementation:

[0045] By rotating the limit nut to adjust the compression amount of the compression spring 18, and then adjust the height of the lifting plate 1, the purpose of contact between the long-axis component 7 and the support roller 6 is achieved, and a supporting effect is played. During the rotational movement of the long-axis component 7, the long-axis component 7 runs more stably under the support of the support roller 6. The setting of the compression spring 18 enables the support roller 6 to have a certain range of motion in height, and can play a supporting role even if the long-axis component 7 is deformed. The compression spring 2 11 can enable the support roller 6 to have a certain range of movement in the horizontal direction, thereby improving the applicability of the device.

[0046] Maintenance operations:

[0047] By adjusting the limit nut, the support roller 6 can be separated from the long shaft parts, and then the bolt 103 of the mounting seat 5 can be removed, and the mounting seat 5 and the support roller 6 can be replaced as a whole without removing the long shaft rotating parts, which is convenient for maintenance operations.
