Description

Technical Field

[0001] This utility model relates to the field of rail, and in particular to an anti-settlement rail system. Background Technology

[0002] Track structures are widely used in transportation, logistics, and other systems, and their structural stability directly affects operational safety and reliability. Traditional track systems typically lay the tracks directly on a base or concrete foundation and fix them with components such as clamping plates. However, during long-term use, the tracks may shift or loosen due to vibrations caused by train operation, lateral impact loads, or slight ground settlement, thereby affecting operational accuracy and structural safety.

[0003] To improve the installation accuracy and service stability of the track, some structures have support plates or connectors under the track. However, most of them still rely on vertical clamping or bolt fastening, lacking effective lateral restraint and anti-lateral displacement structures. Especially when the track is subjected to lateral forces (such as high-speed train turning or side load impact), the support structure is prone to insufficient rigidity, upper plate deformation or track instability.

[0004] Therefore, there is an urgent need for a track support system that combines vertical fixation and lateral reinforcement capabilities to improve its overall resistance to lateral forces and structural stability, ensuring the safe and reliable operation of the track under complex working conditions. This application proposes an anti-settlement track system to address the above problems, featuring multi-directional fixation and strong stability. Utility Model Content

[0005] This utility model provides an anti-settlement track system to solve related technical problems in the background art.

[0006] The technical solution provided by this utility model is as follows: an anti-settlement track system, comprising: a base plate, an upper plate connected to the base plate, a track placed on the upper plate, and a pressure plate connected to the upper plate and fastening the track. The upper plate has a boss at one of its two opposite corners and a bottom plate waist-shaped hole at the other opposite corner. Each boss has a side top seat on its side, and a side top bolt is screwed into the side top seat. The end of the side top bolt is pressed against the side wall of the boss. Each bottom plate waist-shaped hole is fitted with a threaded part to lock it to the bottom plate.

[0007] In one embodiment, the system further includes: pre-embedded anchor bolts, through which the base plate passes and is locked by anchor nuts.

[0008] In one embodiment, leveling bolts are connected to all four corners of the base plate.

[0009] In one embodiment, a U-shaped groove is formed in the side top seat, and a first limiting groove is formed from top to bottom in the U-shaped groove. A side top nut is engaged in the first limiting groove, and a side top bolt passes through the U-shaped groove and is screwed into the side top nut.

[0010] In one embodiment, a second limiting groove is provided on the boss side facing upward and inward.

[0011] In one embodiment, a T-slot is provided on the bottom of the base plate facing upwards, and the threaded parts are a T-bolt and a nut. The T-bolt is placed in the T-slot, passes through the waist-shaped hole of the base plate, and is locked by the nut.

[0012] In one embodiment, a pressure plate T-slot is provided in the boss, and the pressure plate is connected to the boss by the pressure plate T-bolt and pressure plate nut.

[0013] In one embodiment, a pad is provided between the upper plate and the track.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) The anti-settlement track system of this utility model adopts a method in which the upper plate is locked to the bottom plate by threaded parts at one corner to form a vertical fixation, and the other corner is fixed by side bolts to tighten the side wall of the boss to form a horizontal fixation. Through the synergistic effect of the vertical and horizontal clamping structures, the upper plate is stabilized under the action of multi-directional forces, and its overall rigidity and positioning accuracy are improved. Thus, the track system has strong anti-vibration, anti-displacement, and anti-settlement capabilities and long-term stable operation during operation. This solves the technical problem that the existing track structure is easily affected by vibration, settlement or lateral load, resulting in loosening, displacement or insufficient rigidity.

[0017] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0018] This utility model is an anti-settlement track 3 system, which is suitable for scenarios that need to resist lateral disturbances and transverse force transmission of track 3, and can effectively improve the stability and displacement resistance of the structure under lateral load.

[0019] like Figure 1-5 As shown, the anti-settlement track system of this utility model includes: a base plate 1, an upper plate 2 connected to the base plate 1, a track 3 placed on the upper plate 2, and a pressure plate 4 connected to the upper plate 2 for fastening the track 3.

[0020] In this embodiment, the base plate 1 is a metal structural component used to be fixedly laid on the pre-treated foundation and to provide stable support for the superstructure. At the same time, through its high rigidity and distributed force characteristics, it effectively suppresses the overall deformation of the structure caused by foundation settlement and has a certain anti-settlement capability.

[0021] The track 3 is a conventional steel rail or a composite track structure, placed directly on the upper plate 2. To ensure that the track 3 does not shift during operation, it is secured by a pressure plate 4. The pressure plate 4 is connected to the upper plate 2 by fasteners, which can apply a vertical clamping force to the track 3, improving the stability of the track 3 system.

[0022] The two sets of diagonal positions of the upper plate 2 are designed as complementary limiting and locking structures: a boss 5 is provided at one diagonal position, and a side top seat 7 is provided on the side of the boss 5. A side top bolt 8 is screwed into the side top seat 7. The end of the side top bolt 8 is pressed against the side wall of the boss 5, which can provide lateral support and reaction support when the upper plate 2 is subjected to lateral force or uneven stress caused by settlement, further enhancing the overall anti-settlement adaptability of the track system; a bottom plate waist-shaped hole 6 is provided at the other diagonal position, which is convenient to lock with the bottom plate 1 through the threaded part 9, and also has a certain fine adjustment capability to cooperate with the fine position correction during the installation of the track 3.

[0023] As shown in the figure, in this embodiment, pre-embedded anchor bolts 10 are provided below the base plate 1. Specifically, before the track 3 is laid, several sets of anchor bolts 10 are pre-laid in the concrete foundation. When the base plate 1 is installed, the bolt portion of the anchor bolt 10 passes through it, and the anchor nut 11 tightened at the top achieves a firm connection between the base plate 1 and the foundation, effectively preventing the base plate 1 from shifting or sinking due to long-term load, and enhancing the anti-settlement capability of the track system.

[0024] In this embodiment, leveling bolts 12 are provided at each of the four corners of the base plate 1. Each leveling bolt 12 is installed through the base plate 1, and the height difference between the four corners of the base plate 1 and the foundation can be finely adjusted by rotating the bolts, thereby achieving precise adjustment of the posture of the base plate 1. During construction, workers can use a level to assist in tightening or loosening the leveling bolts 12 one by one to make the base plate 1 reach the desired installation level. Alternatively, after foundation settlement or uneven deformation, the posture of the base plate 1 can be restored by readjusting the leveling bolts 12, thus providing anti-settlement adjustment capability during long-term operation.

[0025] Specifically, as shown in the figure, the side top seat 7 has a U-shaped groove 13 inside, which extends downward from the opening and forms a first limiting groove 14 on its inner side. During installation, the side top nut 15 is pre-clamped into the first limiting groove 14 to limit and fix it in the axial direction, preventing misalignment or loosening as the bolt rotates. Subsequently, the side top bolt 8 passes through the U-shaped groove 13 of the side top seat 7 and is screwed into the side top nut 15. After tightening, the bolt end presses against the side wall of the adjacent boss 5 to apply a lateral preload.

[0026] In this embodiment, a boss 5 is provided at one of the corners of the upper plate 2, and a side top seat 7 and a side top bolt 8 are provided. The side top bolt 8 is used to tighten the side wall of the boss 5 to apply a lateral preload to the upper plate 2, thereby improving the ability of the upper plate 2 to resist lateral forces. This achieves the technical effect that the track 3 remains stable and does not shift under lateral load.

[0027] Furthermore, a second limiting groove 16 is provided on the side of the boss 5. This limiting groove can be used to help limit the range of motion of the end of the side top bolt 8, thereby improving the positioning accuracy and fatigue stability of the lateral support structure during long-term service.

[0028] In this embodiment, as shown in the figure, a bottom plate waist-shaped hole 6 is opened at one of the diagonal positions of the upper plate 2, and is locked to the bottom plate 1 by a threaded component 9; a bottom plate T-slot 17 is opened on the lower surface of the bottom plate 1, and the bottom plate waist-shaped hole 6 corresponds to the position of the T-slot; in this embodiment, the threaded component 9 is a bottom plate T-bolt 91 and a bottom plate nut 92; during installation, the bottom plate T-bolt 91 is inserted into the T-slot, so that its threaded part passes through the corresponding bottom plate waist-shaped hole 6, and the bottom plate nut 92 is tightened above. This connection method not only provides a strong vertical fixing force, but also, due to the axially adjustable characteristic of the bottom plate waist-shaped hole 6, the position of the upper plate 2 can be finely adjusted without loosening the bottom plate 1 as a whole, meeting the high precision requirements when laying the track 3.

[0029] In this embodiment, a T-slot 18 for the pressure plate is provided inside the boss 5. By inserting the T-bolt 19 of the pressure plate into the T-slot and passing it through the pressure plate 4, and then tightening the pressure plate nut 20 above the pressure plate 4, a stable connection between the pressure plate 4 and the boss 5 is achieved; the pressure tongue at the front of the pressure plate 4 fastens the track 3. This structure allows the pressure plate 4 to move or be replaced within a certain range, adapting to different models or sizes of track 3 structures, and has good versatility and adaptability.

[0030] Preferably, in order to improve the contact stability and damping characteristics between the track 3 and the upper plate 2, a pad 21 is provided above the upper plate 2. The pad 21 can be made of rubber material to alleviate the high-frequency vibration generated during vehicle operation, improve the vibration reduction capability of the track 3 and the fatigue life of the system; at the same time, it also plays a role in fine height adjustment, further improving the laying accuracy of the track 3.

[0031] Working principle: During the installation of the track 3 system, the base plate 1 is first fixed to the foundation. The base plate 1 is reliably anchored by the pre-embedded anchor bolts 10 and anchor nuts 11. At the same time, the posture of the base plate 1 is precisely adjusted by the leveling bolts 12 set at the four corners of the base plate 1 to ensure that it is installed horizontally. Subsequently, the upper plate 2 is installed onto the base plate 1 and locked to the base plate 1 by means of the waist-shaped holes located at one diagonal position of the upper plate 2 and the pressure plate T-bolts 19 and pressure plate nuts 20; the other diagonal position is tightened laterally by the side top bolts 8; the track 3 is placed on the upper plate 2 and fastened by the pressure plate 4.

[0032] In this embodiment, the upper plate 2 is vertically fixed by locking it to the bottom plate 1 at one diagonal position with threaded parts 9, and horizontally fixed by tightening the side wall of the boss 5 with side bolts 8 at the other diagonal position. Through the synergistic effect of the vertical and horizontal clamping structures, the upper plate 2 is stabilized under the action of multi-directional forces, and its overall rigidity and positioning accuracy are improved. This achieves the technical effect of strong anti-vibration, anti-displacement, and anti-settlement capabilities and long-term stable operation of the track 3 system during operation, and solves the technical problem that the existing track 3 structure is easily affected by vibration, settlement or lateral load, resulting in loosening, displacement or insufficient rigidity.
