[0035] Example 1

[0036] Please refer to Figures 1-6The utility model provides a square rail slider bearing device special for rail vehicle, including: square rail 1, the upper side of square rail 1 is slidably fitted with slider main body 2, and the sliding assembly 3 is arranged between slider main body 2 and square rail 1, the upper side of slider main body 2 is installed with bearing block 4, and the bearing assembly 5 is arranged between bearing block 4 and slider main body 2, square rail 1 is recessed towards the inside along its length direction and is provided with guide recess 9. Dust baffle 6 is installed at both ends of square rail 1, and a plurality of threaded grooves 7 are formed in the side edges of both ends of square rail 1, and the side edges of dust baffle 6 are provided with mounting bolts 8 which are threadedly engaged with threaded grooves 7. Drainage groove 10 is formed in the bottom of guide recess 9, and drainage groove 10 penetrates along the length direction of square rail 1, and drainage holes 11 are formed in the bottom of drainage groove 10 at intervals. Bearing assembly 5 includes a plurality of dampers 501 and buffer springs 502 which are installed between slider main body 2 and square rail 1, and rust-proof corrugated pipe 503 is sleeved on buffer spring 502 and installed between slider main body 2 and square rail 1. Anti-skid pattern 504 is arranged on the top surface of bearing block 4, and mounting blocks 505 are arranged at the four corners of bearing block 4.

[0037] Implementation process: bearing block 4 is installed on slider main body 2 through bearing assembly 5. The plurality of dampers 501 and buffer springs 502 in bearing assembly 5 work cooperatively, when bearing block 4 is subjected to upward load pressure, buffer spring 502 is first compressed to absorb part of the impact force, thereby achieving the effect of preliminary buffering. Damper 501 restrains the excessive elastic deformation of buffer spring 502 to prevent secondary impact caused by spring rebound, thereby making the bearing more stable. Rust-proof corrugated pipe 503 is sleeved on buffer spring 502 to prevent external moisture, dust and other substances from eroding the spring, thereby prolonging the service life of the spring and ensuring long-term stable bearing performance; dust baffle 6 at both ends of square rail 1 is fixed on threaded groove 7 through mounting bolt 8, which effectively prevents dust, debris and other substances from entering the gap between the rail and the slider, thereby preventing problems such as jamming and wear caused by the entry of foreign matter and ensuring smooth sliding.

[0038] Implementation benefits: reliable bearing support is provided for bearing block 4, and the impact force from above is effectively buffered.

[0039] Example 2

[0040] The sliding assembly 3 comprises guide blocks 301 arranged on the inner walls of the two sides of the guide groove 9, and a plurality of guide rollers 302 are rotatably arranged on the bottom of the sliding block body 2 and cooperated with the guide blocks 301.

[0041] Implementation process: the sliding block body 2 and the square guide rail 1 are relatively slid by the sliding assembly 3. The guide blocks 301 arranged on the inner walls of the two sides of the guide groove 9 provide lateral guidance for the sliding of the sliding block body 2, and ensure the stable movement of the sliding block body 2 along the square guide rail 1. The plurality of guide rollers 302 on the bottom of the sliding block body 2 are located between the two guide blocks 301 and cooperated with the guide blocks 301, and the rolling friction greatly reduces the resistance of the sliding block during movement, so that the sliding block can smoothly slide on the guide rail. The damping rubber blocks 303 not only have a certain buffering effect to reduce the hard impact between the guide rail and the sliding block due to vibration, but also assist in supporting the sliding block body 2 to ensure the stability of the overall structure. The oil inlet 305 on the top surface of the sliding block body 2 and the oil inlet groove 306 connected thereto provide a lubrication path for the roller bearing 304. The operator can inject lubricating oil through the oil inlet 305, and the lubricating oil flows to the roller bearing 304 along the oil inlet groove 306, which reduces the wear of the bearing during rotation, ensures the smooth operation of the guide roller 302, reduces the operating resistance of the equipment, and prolongs the equipment maintenance cycle.

[0042] Implementation benefits: the frictional resistance of the sliding block body 2 sliding on the square guide rail 1 is reduced.
