Description

Technical Field

[0001] This utility model relates to the field of railway track technology, and in particular to a railway track foundation support mechanism that can be quickly assembled. Background Technology

[0002] The rapidly assembled railway track foundation support mechanism is an innovative railway track infrastructure solution designed to address the problems of long construction cycles, poor structural stability, and high maintenance costs associated with traditional railway track construction. Employing a prefabricated and modular design concept, the mechanism achieves rapid installation and precise positioning of the track foundation through standardized interfaces and mechanical connections. It also boasts excellent vibration damping performance and environmental adaptability, making it widely applicable to various scenarios including high-speed railways, intercity railways, and heavy-haul railways.

[0003] Traditional railway track foundations mostly use cast-in-place concrete bases, which require processes such as formwork, pouring, and curing. They are greatly affected by weather and environment, especially during winter or rainy season when construction efficiency drops significantly. Once damage occurs, the entire track needs to be excavated and repaired, resulting in a large amount of work. Traditional tracks use crushed stone ballast or simple cushioning layers for shock absorption, but the elastic buffering effect is limited. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a railway track foundation support mechanism that can be quickly assembled.

[0005] This utility model is achieved by the following technical solution: a railway track foundation support mechanism that can be quickly assembled, including a prefabricated base, a connecting support base fixedly connected to the upper surface of the prefabricated base, several first fixing holes opened on both sides of the upper surface of the prefabricated base, several first bolts fixedly connected to both sides of the connecting support base, the first bolts being adapted to the first fixing holes, and several limiting supports fixedly connected to the middle of the upper surface of the prefabricated base.

[0006] Through the above technical solution, the precast base and the connecting support base are connected by the first bolt and the first fixing hole, realizing modular installation, reducing on-site construction time, improving efficiency, and the setting of the limiting support enhances the positioning accuracy of the upper and lower components, avoids installation deviation, and ensures the stability of the overall structure. The precast base can be pre-processed, reducing the curing time of on-site concrete pouring and meeting the needs of rapid construction in railway engineering.

[0007] As a further improvement to the above solution, several support limiting holes are provided in the middle of the upper surface of the connecting support base, and the support limiting holes are adapted to the limiting supports.

[0008] Through the above technical solution, the limiting hole of the support pier is adapted to the limiting support pier, which further strengthens the positioning of the connecting support base and the precast base, avoids horizontal displacement, and simplifies the installation process. The positioning structure can ensure the alignment of components without additional measuring tools, thus reducing the difficulty of construction.

[0009] As a further improvement to the above solution, an installation groove is provided in the middle of the inner wall of the connecting support base. A prefabricated track plate is slidably connected to the upper surface of the installation groove. A slider is fixedly connected to the middle of the lower surface of the prefabricated track plate. Limiting blocks are fixedly connected to both sides of the prefabricated track plate.

[0010] Through the above technical solution, the precast track slab is slidably connected to the installation groove by a slider, which can be laid quickly, reducing hoisting time. The limiting block prevents the track slab from moving laterally, enhances the anti-tilting ability of the track system, and improves driving safety.

[0011] As a further improvement to the above solution, several rail fixing devices are fixedly connected to both sides of the upper surface of the precast track slab, and rails are fixedly connected to the upper surface of the rail fixing devices.

[0012] Through the above technical solution, the rail fixing device stably fixes the rail to the precast track slab, ensuring that the rail does not shift when the train is running. The device is integrated with the precast track slab, which facilitates overall replacement or maintenance and reduces the cost of later maintenance.

[0013] As a further improvement to the above solution, the rail fixing device includes a concrete sleeper, a fixing groove is provided in the middle of the inner wall of the concrete sleeper, and a second fixing hole is provided on both sides of the inner wall of the concrete sleeper. A rail pad and an elastic pad are fixedly connected to the inner wall of the fixing groove from top to bottom.

[0014] Through the above technical solutions, the elastic pad and rail pad can absorb the vibration of the train during operation, reduce noise, and extend the service life of the track. The fixing groove design allows the rail load to be evenly transferred to the concrete sleeper, avoiding local stress concentration. The second fixing hole provides positioning for bolt connection and facilitates quick installation of the rail fixing plate.

[0015] As a further improvement to the above solution, rail fixing plates are fixedly connected to both sides of the upper surface of the concrete sleeper. The inner wall of the rail fixing plate is fixedly connected with a second bolt by thread. The second bolt is adapted to the second fixing hole, and the rail fixing plate is adapted to the rail.

[0016] Through the above technical solution, the second bolt cooperates with the second fixing hole to adjust the clamping force of the rail fixing plate and adapt to different rail models.

[0017] As a further improvement to the above solution, mounting grooves are provided on both sides of the lower surface of the connecting support base. A shock-absorbing strip is fixedly connected to the inner wall of the mounting groove. Several adapter holes are provided on the upper surface of the shock-absorbing strip, and the adapter holes are adapted to the limiting support.

[0018] Through the above technical solution, the shock-absorbing strip is set between the connecting support base and the precast base, forming a double shock absorption with the elastic pad layer, reducing the impact of train vibration on the roadbed. The adapter hole and the limiting support pier cooperate to ensure that the shock-absorbing strip does not shift when under force, thus maintaining the shock absorption effect.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model uses prefabricated bases, connecting support bases, and prefabricated track slabs, all of which are factory-prefabricated components. On-site assembly is achieved through bolts (first bolt, second bolt, and sliding groove installation), avoiding the curing time of traditional cast-in-place concrete. The structure of limiting supports and supporting limit holes, sliders and sliding grooves allows for plug-and-play installation, reducing on-site measurement and adjustment procedures. It is suitable for emergency repairs or large-scale railway construction.

[0021] 2. This utility model prevents the connecting support base from lifting by setting a limiting pier to insert into the limiting hole of the pier. The limiting block of the precast track slab engages with the edge of the sliding groove to resist the lateral impact force of the train and ensure the stability of the track geometry. The rail fixing device, precast track slab and other components can be disassembled and replaced individually without overall rework. The elastic deformation of the shock absorption belt can alleviate the impact of minor foundation settlement. The rigid design of the precast base avoids track deformation caused by local collapse. It is suitable for complex geological areas such as soft soil and frozen soil. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5 The railway track foundation support mechanism of this embodiment that can be quickly assembled includes a prefabricated base 1. A connecting support base 2 is fixedly connected to the upper surface of the prefabricated base 1. Several first fixing holes 3 are opened on both sides of the upper surface of the prefabricated base 1. Several first bolts 4 are fixedly connected to both sides of the connecting support base 2. The first bolts 4 are adapted to the first fixing holes 3. Several limiting supports 5 are fixedly connected to the middle of the upper surface of the prefabricated base 1. The prefabricated base 1, as a basic component, is connected to the first bolts 4 of the connecting support base 2 through the first fixing holes 3 to form a detachable rigid connection. The limiting supports 5 protrude upward to provide a positioning reference for the upper component and ensure the verticality and horizontality of the connecting support base 2 during installation.

[0032] Several support limiting holes 6 are provided in the middle of the upper surface of the connecting support base 2. The support limiting holes 6 are adapted to the limiting supports 5. The limiting supports 5 are inserted into the support limiting holes 6 to form a convex-concave fit structure. The position of the connecting support base 2 can be locked before the bolts are fixed to ensure the installation accuracy.

[0033] An installation groove 7 is provided in the middle of the inner wall of the connecting support base 2. A prefabricated track slab 8 is slidably connected to the upper surface of the installation groove 7. A slider 801 is fixedly connected to the middle of the lower surface of the prefabricated track slab 8. Limiting blocks 802 are fixedly connected to both sides of the prefabricated track slab 8. The slider 801 at the bottom of the prefabricated track slab 8 is embedded in the installation groove 7 of the connecting support base 2. The track slab is laid by horizontal sliding. The limiting blocks 802 are in contact with the inner wall of the connecting support base 2 to limit the lateral displacement of the track slab and form a stable support structure.

[0034] Several rail fixing devices 9 are fixedly connected to both sides of the upper surface of the precast track slab 8. Rails 10 are fixedly connected to the upper surface of the rail fixing devices 9. The rail fixing devices 9 are connected to the precast track slab 8 by bolts or buckles. The clamping components on the upper part of the devices hold the rails 10 tightly to the track slab and bear the train load and lateral force.

[0035] The rail fixing device 9 includes a concrete sleeper 901. A fixing groove 902 is provided in the middle of the inner wall of the concrete sleeper 901. A second fixing hole 903 is provided on both sides of the inner wall of the concrete sleeper 901. A rail pad 905 and an elastic pad 904 are fixedly connected to the inner wall of the fixing groove 902 from top to bottom. The bottom of the rail 10 contacts the concrete sleeper 901 through the rail pad 905 and the elastic pad 904. The elastic pad absorbs vibration energy. The train load is transferred to the pad and the pad through the rail, and then evenly distributed to the concrete sleeper and the supporting structure below.

[0036] Both sides of the upper surface of the concrete sleeper 901 are fixedly connected to rail fixing plates 906. The inner wall of the rail fixing plate 906 is fixedly connected to a second bolt 907 by thread. The second bolt 907 is adapted to the second fixing hole 903. The rail fixing plate 906 is adapted to the rail 10. The rail fixing plate 906 is fixed to the concrete sleeper 901 by the second bolt 907. Its inner edge presses against the rail web of the rail 10. The clamping force is adjusted by adjusting the bolt torque to achieve stable fixing of the rail.

[0037] Both sides of the lower surface of the connecting support base 2 are provided with mounting grooves 11. The inner wall of the mounting groove 11 is fixedly connected with a shock-absorbing belt 12. Several adapter holes 13 are provided on the upper surface of the shock-absorbing belt 12. The adapter holes 13 are adapted to the limiting support 5. The vibration generated when the train is running is transmitted to the connecting support base 2 through the track plate. Then, the energy is absorbed by the elastic deformation of the shock-absorbing belt 12, reducing the transmission of vibration to the precast base 1 and the roadbed. The limiting support 5 is inserted into the adapter holes 13 to restrict the lateral movement of the shock-absorbing belt and ensure that it maintains stable shock absorption performance under long-term stress.

[0038] Working principle: The foundation is stabilized by pre-embedding or on-site fixing. The first fixing hole 3 and the limiting support 5 on the upper surface provide positioning reference for the upper components. The limiting support 5 prevents horizontal displacement by inserting into the support limiting hole 6 of the connecting support base.

[0039] The first bolt 4 is fixed to the precast base. The mounting groove 7 on the inner wall is used to support the precast track slab. The mounting groove 11 and the shock-absorbing belt 12 at the bottom cooperate with the limiting support 5 to form a shock-absorbing buffer layer. The shock-absorbing belt 12 absorbs track vibration through elastic material and reduces the impact on the foundation.

[0040] The bottom slider 801 is embedded in the mounting groove 7, and the two side limit blocks 802 engage with the edge of the groove to prevent lateral displacement. The upper surface is connected to the rail through the rail fixing device 9. The rail fixing device 9 consists of a concrete sleeper 901, an elastic pad 904, a rail pad 905, and a rail fixing plate 906. The elastic pad 904 and the rail pad 905 are laid in the fixing groove 902 to buffer the direct impact between the rail and the concrete sleeper. The rail fixing plate 906 is connected to the second fixing hole 903 of the concrete sleeper through the second bolt 907 to clamp the rail 10.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
