Abstract

This application provides a rail vibration damping component and a rail device. The rail vibration damping component includes a base, two support seats, a rail, and two damping seats. Both support seats are mounted on the same base and are embedded in the base. The two support seats are arranged opposite to each other and form a receiving groove. Each support seat has a locking arm. The rail is received in the receiving groove and has a bottom support arm. Both damping seats are located within the receiving groove, each damping seat contacting the rail and the support seat and filling the gap between them.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0041] Please refer to the attached document. Figures 1-6 This application provides a rail vibration damping component 100, which is applied to a rail 30 device and is used to dampen vibration and perform multi-directional positioning on the rail 30.

[0042] Please refer to the attached document. Figures 1-6In this embodiment, the rail vibration damping assembly 100 includes a base 10, two support seats 20, a rail 30, and two damping seats 40. Both support seats 20 are mounted on the same base 10 and are embedded in the base 10. The two support seats 20 are arranged opposite to each other and form receiving grooves 20a. Each support seat 20 is provided with a locking arm 21. The rail 30 is received in the receiving groove 20a and has a bottom support arm 31. Both damping seats 40 are located within the receiving groove 20a, and each damping seat 40 contacts the rail 30 and the support seat 20, filling the groove. The gap between the rail 30 and the support 20; the vibration damping seat 40 is provided with a corner end 41, which contacts the locking arm 21 and is connected to the locking arm 21 in a locking connection structure; the vibration damping seat 40 is provided with a locking groove 40a, which is connected to the bottom support arm 31 in a locking connection to perform multi-directional positioning of the rail 30, so that the two vibration damping seats 40 can perform vibration damping and multi-directional positioning of the rail 30, thereby making the rail 30 unable to move, avoiding the situation where the vibration damping seat 40 only limits the position in one direction and the rail 30 is easy to loosen, thus improving the vibration damping effect of the rail vibration damping assembly 100.

[0043] Please refer to the attached document. Figures 1-6 In this embodiment, the base 10 serves as a support part of the rail vibration damping assembly 100, and is used to support two support seats 20, the rail 30, and two vibration damping seats 40. Optionally, the base 10 is connected to the external ground by bolts.

[0044] Both support bases 20 are installed on the same base 10 and are embedded in the base 10, which ensures the installation stability of the two support bases 20 relative to the base 10; the two support bases 20 are arranged opposite to each other and form a receiving groove 20a; the support base 20 is provided with a locking arm 21.

[0045] The rail 30 is accommodated in the receiving groove 20a so that the rail 30 can be fixed between the two support seats 20, thereby making full use of the space of the receiving groove 20a; the rail 30 is provided with a bottom support arm 31.

[0046] Both vibration damping seats 40 are located within the receiving groove 20a. Each vibration damping seat 40 contacts the rail 30 and the support seat 20, filling the gap between the rail 30 and the support seat 20, so that the two surfaces of each vibration damping seat 40 respectively contact the rail 30 and the support seat 20. The vibration damping seat 40 is provided with a corner end 41, which contacts the locking arm 21 and forms a locking connection with the locking arm 21, ensuring the connection stability between the vibration damping seat 40 and the support seat 20. The vibration damping seat 40 is provided with a locking groove. 40a, the engaging groove 40a is engaged with the bottom support arm 31 to perform multi-directional positioning of the rail 30, so that the two vibration damping seats 40 can perform vibration damping and multi-directional positioning of the rail 30, thereby making the rail 30 unable to move. This avoids the situation where the vibration damping seat 40 only restricts the position in one direction and the rail 30 is easy to loosen, thus improving the vibration damping effect of the rail vibration damping component 100. It realizes the prefabricated structure design, and at the same time has excellent vibration damping effect and construction convenience. The prefabricated structure design is conducive to construction and maintenance.

[0047] Please refer to the attached document. Figures 1-3 In this embodiment, the rail 30 has a main body 32, which is connected to the bottom support arm 31. The main body 32 is located on the upper side of the bottom support arm 31 to facilitate the fixation of the main body 32 to the upper side of the bottom support arm 31, ensuring the stability and integrity of the rail 30. The sidewalls of each vibration damping seat 40 facing the rail 30 are in contact with the sidewalls of the main body 32. A cavity 40b is formed between two vibration damping seats 40, which is used for the rail 30 to pass through. The inner sidewall of the cavity 40b is in contact with the sidewalls of the main body 32 and the bottom support arm 31, ensuring that the vibration damping seat 40 can effectively absorb and disperse the vibrations generated by the rail 30 during operation. Simultaneously, the tight fit between the inner sidewall of the cavity 40b and the main body 32 and the bottom support arm 31 creates a relatively enclosed environment, reducing the erosion of the main body 32 and the bottom support arm 31 by external factors.

[0048] Please refer to the attached document. Figures 1-3 In this embodiment, the vibration damping seat 40 incorporates a resonant mass damping block 42. The vibration damping seat 40 and the resonant mass damping block 42 form an integrated structure, improving the connection strength between them and ensuring connection stability. The resonant mass damping block 42 is used to reduce low-frequency and high-frequency vibrations, allowing the vibration damping seat 40 to integrate both low-frequency and high-frequency vibration reduction effects. Optionally, the vibration damping seat is a longitudinally continuous support fastener structure, making the under-rail support stiffness more uniform. This resonant mass damping block 42 effectively addresses the generation and development of abnormal rail corrugation, providing a certain damping effect and improving vibration reduction performance.

[0049] Please refer to the attached document. Figures 1-3In embodiment 6 of this application, two adjacent vibration damping seats 40 are in contact with each other in the receiving groove 20a and are flatly mated together; this ensures a tight connection between the vibration damping seats 40 and avoids vibration transmission or structural instability caused by gaps or unevenness. The outer wall of the bottom support arm 31 is arranged at an angle, and the inner wall of the engaging groove 40a is adapted to the outer wall of the bottom support arm 31, so as to improve the contact area and contact angle between the inner wall of the engaging groove 40a and the outer wall of the bottom support arm 31, thereby enhancing the stability and vibration damping effect of the vibration damping seat 40 and the rail 30.

[0050] Please refer to the attached document. Figures 1-5 In this embodiment, the base 10 is provided with an embedding groove 10a; the support 20 is provided with an L-shaped support arm 22, which is embedded in the embedding groove 10a and restricted by the inner sidewall of the embedding groove 10a, ensuring that the L-shaped support arm 22 remains stable within the embedding groove 10a and preventing the support 20 from shifting or loosening relative to the base 10; the L-shaped support arm 22 is connected to a reinforcing rib 221, which can distribute and bear external forces, enhancing the stability of the L-shaped support arm 22. Simultaneously, the L-shaped support arm 22 provides support for the base 10 and the vibration damping seat 40.

[0051] Please refer to the attached document. Figures 1-5 In this embodiment, there are multiple L-shaped support arms 22, which are arranged along the length of the support base 20. By arranging multiple L-shaped support arms 22, the support force of the base 10 and the vibration damping seat 40 is increased. A first mounting seat 222 is connected between two adjacent L-shaped support arms 22. The first mounting seat 222 is detachably mounted on the base 10 so that the first mounting seat 222 can be connected to or detached from the base 10. This facilitates the connection or detachment of multiple L-shaped support arms 22 relative to the base 10 through the first mounting seat 222, thereby improving the ease of mounting and dismounting of the support base 20.

[0052] Please refer to the attached document. Figures 1-5 In this embodiment, the base 10 is provided with a second mounting seat 11, which is inserted into the first mounting seat 222, so that the second mounting seat 11 and the first mounting seat 222 are in a snap-fit ​​connection structure, so that multiple L-shaped support arms 22 can be detachably connected through the cooperation of the first mounting seat 222 and the second mounting seat 11. When the second mounting seat 11 and the first mounting seat 222 are snapped together, the multiple L-shaped support arms 22 are in a stationary state relative to the base 10. When the second mounting seat 11 is disengaged from the first mounting seat 222, the multiple L-shaped support arms 22 are disengaged from the base 10.

[0053] Please refer to the attached document. Figures 1-5In this embodiment, the second mounting base 11 is provided with a groove 11a for the screw to pass through, so that the second mounting base 11 can avoid the screw through the space of the groove 11a, thereby facilitating the screw to pass through the second mounting base 11. The end of the screw is located in the groove 11a, and the threaded end of the screw passes through the second mounting base 11 and the first mounting base 222, and can be connected with an external nut, so that the screw and the external nut can cooperate to further strengthen the connection strength between the first mounting base 222 and the second mounting base 11, ensuring the connection stability between the first mounting base 222 and the second mounting base 11, and preventing the first mounting base 222 and the second mounting base 11 from separating during use.

[0054] Please refer to the attached document. Figures 1-5 In this embodiment, the side wall of the support base 20 is provided with two limiting protrusions 23, which are arranged opposite to each other along the length of the support base 20. The opposite side walls of the vibration damping seat 40 respectively contact the corresponding limiting protrusions and are limited by the two limiting protrusions, so that the support base 20 can limit the different positions of the vibration damping seat 40 by the two limiting protrusions 23, thereby facilitating the base 10 and the support base 20 to cooperate in limiting the vibration damping seat 40 in multiple directions and ensuring the multi-directional positioning of the vibration damping seat 40.
