Description

A composite frame track foundation Technical Field

[0001] This utility model relates to a combined frame type track foundation. Background Technology

[0002] Currently in China, dynamic track scales or dynamic overload / off-center load detection devices are required to weigh and inspect the loading capacity and quality of freight cars in operation. To ensure detection accuracy, high requirements are placed on the stability and rigidity of the track foundation in the installation section. Previous practices have involved using monolithic concrete foundations or custom-made sleepers connected together to form a single foundation. Monolithic concrete foundations involve excavating a pit on the track bed, laying reinforcing steel, pouring concrete, and curing. Custom-made sleepers (rectangular in shape) are pre-made with embedded steel structural components. These sleepers are then transported to the installation location, replacing existing ordinary sleepers (such as concrete sleepers), and finally connected into a single frame using connectors. All these methods suffer from drawbacks such as long construction time, significant disruption to train operations, and poor economic efficiency. Summary of the Invention

[0003] This utility model provides a combined frame-type track foundation that meets usage requirements, is easy to install and use, and is inexpensive.

[0004] The technical solution adopted by this utility model is: a combined frame-type track foundation, wherein adjacent concrete sleepers in the track foundation are connected by a frame-type connecting mechanism; the frame-type connecting mechanism includes a bottom support frame and an upper retaining beam; in the assembled state, the bottom support frame is placed on the lower bottom surface of the adjacent sleeper end, and the upper retaining beam is flatly installed on the upper end surface of the adjacent sleeper, and the bottom support frame and the upper retaining beam are fastened together by connecting components; after the frame-type connecting mechanism is installed and tightened at both ends of the adjacent sleepers, they form a connected whole that locks the sleeper ends together, forming an independent integral track foundation.

[0005] The further technical solution is as follows: the bottom support frame includes a bottom support beam, threaded columns, and reinforcing ribs; the reinforcing ribs are arranged on the bottom support beam, and the threaded columns are arranged on the bottom support beam, located on both sides of the reinforcing ribs; in the assembled state, the threaded columns are located between adjacent sleeper ends.

[0006] The further technical solution is: the upper barrier beam is a sheet metal bending part, and the inner groove surface is provided with bolt through holes corresponding to the threaded column.

[0007] The further technical solution is that the bottom support beam is a single-piece structure or a multi-segment structure spliced ​​together.

[0008] The further technical solution is that the upper barrier beam is a single-piece structure or a multi-segment structure spliced ​​together.

[0009] A further technical solution is that the connecting component is a bolt assembly.

[0010] By adopting the above technical solution, one of the combined frame track foundations of this utility model has the following beneficial effects:

[0011] 1. The frame-type track foundation of this utility model is based on the track foundation, which is the same as the line foundation. The line foundation retains the original line foundation unchanged. There is no need to replace it with special overload sleepers or adjust the spacing of the original sleepers (such as concrete sleepers). It only requires the use of the sleeper connection mechanism to connect the original sleepers (such as concrete sleepers) into an integral frame structure, which is fixed and balanced as a whole, providing sufficient stability, ensuring detection accuracy, and greatly reducing the amount of construction work.

[0012] 2. The sleeper connection mechanism of this utility model has a simple, reasonable, reliable, and low-cost structure. It makes full use of the existing sleepers on the track and can connect ordinary cement sleepers (concrete sleepers) into a frame-type sleeper foundation without replacing them with new, specially customized sleepers.

[0013] 3. The assembly of the pillow-to-pillow connection mechanism of this utility model is simple, which greatly reduces the workload of the entire construction and minimizes interference with traffic.

[0014] 4. Saves a lot of manpower and resources in production, transportation, and replacement.

[0015] 5. Easy to use and maintain.

[0016] The technical features of a combined frame track foundation of this utility model will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0034] A composite frame-type track foundation is provided, wherein adjacent concrete sleepers 3 are connected by a frame-type connecting mechanism. The frame-type connecting mechanism includes a bottom support frame 1 and an upper retaining beam 2. In the assembled state, the bottom support frame 1 is placed on the lower surface of the end of the adjacent sleeper, and the upper retaining beam 2 is flatly installed on the upper surface of the corresponding adjacent sleeper. The bottom support frame 1 and the upper retaining beam 2 are fastened together by a connecting component. After the frame-type connecting mechanism is installed and tightened at both ends of the adjacent sleepers, they form a connected whole that locks the sleeper ends together, forming an independent integral track foundation.

[0035] The base support frame 1 is an integral structure welded from multiple individual components, including a base support beam, threaded posts 12, and reinforcing ribs 13. The reinforcing ribs 13 are set on the base support beam, and the threaded posts 12 are set on the base support beam, generally located on both sides of the reinforcing ribs. In the assembled state, the threaded posts 12 are located between adjacent sleeper ends, which facilitates the fastening and installation of the base support frame 1 and the upper railing beam 2.

[0036] The upper barrier beam 2 is a sheet metal bending part, and the inner groove surface is provided with bolt through holes corresponding to the threaded column.

[0037] The bottom support beam is either a single-piece structure or composed of multiple sections spliced ​​together.

[0038] The upper barrier beam 2 is either a single-piece structure or composed of multiple segments spliced ​​together.

[0039] The connecting component is a bolt assembly.

[0040] Depending on the structure and length of the bottom support beam and the upper barrier beam 2, there are several different implementation methods. Example 1:

[0041] As shown in Figures 1-6, a combined frame-type track foundation is provided. Adjacent concrete sleepers 3 are connected by a frame-type connecting mechanism. This mechanism includes a bottom support frame 1 and an upper retaining beam 2. The bottom support frame 1 includes a bottom support beam, threaded columns 12, and reinforcing ribs 13. Both the bottom support beam and the upper retaining beam 2 are integral structures. The following example illustrates a track foundation consisting of three adjacent concrete sleepers forming an independent, integrated structure. The ends of the three adjacent concrete sleepers are connected and fixed by the frame-type connecting mechanism, and the left and right ends are symmetrically installed, forming an independent, integrated track foundation. The bottom support beam is an integral structure bottom support beam 1a, and the upper retaining beam 2 is an integral structure upper retaining beam 2a. The lengths of the integral bottom support beam 1a and the integral upper retaining beam 2a are determined by the length of the overall track foundation. For example, in this embodiment, the length of the integral bottom support beam 1a spans across the three adjacent concrete sleepers, and the length of the integral upper retaining beam 2a is equal to the length of the integral bottom support beam 1a. The integrated bottom support beam 1a is provided with two reinforcing ribs 13, and threaded posts 12 are respectively provided on both sides of the two reinforcing ribs 13. The bottom of the threaded posts 12 is welded to the integrated bottom support beam 1a, and the side of the threaded posts 12 is welded to the reinforcing ribs 13. A threaded post 12 is also provided at each end of the integrated bottom support beam 1a.

[0042] The upper barrier beam 2 is a sheet metal bending part with 6 bolt through holes on the inner groove surface. The hole spacing is consistent with the hole spacing on the inner groove surface of the bottom support beam 1a of the integrated structure, and the upper and lower parts are symmetrical.

[0043] In the assembled state, the bottom support frame 1 is placed on the lower surface of the sleeper end, with the center aligned with the center of the middle sleeper and the threaded post 12 facing upwards. The upper retaining beam 2 is installed flat on the upper end face of the sleeper from top to bottom. The six sets of threaded posts 12 are each aligned with the through holes passing through the inner groove surface of the upper retaining beam 2, and then fastened together with nuts and washers. After the frame-type connecting mechanism of the left and right sleeper ends is installed and tightened, it forms a connecting whole that locks the sleeper end sides together, forming an independent integral track foundation. Example 2:

[0044] As shown in Figures 7-9, a combined frame-type track foundation is provided. Adjacent concrete sleepers 3 are connected by a frame-type connecting mechanism. This mechanism includes a bottom support frame 1 and an upper retaining beam 2. The bottom support frame 1 includes a bottom support beam, threaded columns 12, and reinforcing ribs 13. Both the bottom support beam and the upper retaining beam 2 are composed of multiple segments. The following example illustrates a single, independent track foundation formed by three adjacent concrete sleepers. The ends of the three adjacent concrete sleepers are connected and fixed by the frame-type connecting mechanism, and the left and right ends are symmetrically installed, forming a single, independent track foundation. In this embodiment, the bottom support beam is a multi-segment bottom support beam 1b, and the upper retaining beam 2 is a multi-segment upper retaining beam 2b. The lengths of the multi-segment bottom support beam 1b and the multi-segment upper retaining beam 2b are determined by the length of the overall track foundation and are composed of multiple segments. In this embodiment, the multi-segment bottom support beam 1b is composed of two segments spliced ​​together. Each segment of the bottom support beam is provided with a reinforcing rib 13. A threaded post 12 is provided on both sides of the reinforcing rib 13. The bottom of the threaded post 12 is welded to the multi-segment bottom support beam 1b, and the side of the threaded post 12 is welded to the reinforcing rib 13. The multi-segment upper barrier beam 2b is also composed of two segments spliced ​​together. The inner groove surface of each segment is provided with bolt through holes corresponding to the threaded posts.

[0045] In the assembled state, the two multi-segment bottom support beams 1b are aligned with the center of the adjacent sleepers and placed on the bottom surface of the sleeper ends, with the threaded posts 12 facing upwards. The two multi-segment upper restraining beams 2b are respectively installed flat on the upper end face of the sleepers, corresponding to the two multi-segment bottom support beams 1b. The four sets of threaded posts 12 are each aligned with the through holes passing through the inner groove surface of the upper restraining beam 2, and then the connection is secured with nuts and washers. After the frame-type connecting mechanism of the left and right sleeper ends is installed and tightened, it forms a connecting whole that locks the sleeper ends together, forming an independent integral track foundation. Example 3:

[0046] As shown in Figures 10-12, a combined frame-type track foundation is provided. Adjacent concrete sleepers 3 are connected by a frame-type connecting mechanism. The frame-type connecting mechanism includes a bottom support frame 1 and an upper retaining beam 2. The bottom support frame 1 includes a bottom support beam, threaded posts 12, and reinforcing ribs 13. The bottom support beam is composed of multiple segments, while the upper retaining beam 2 is a single, integral structure. The following explanation uses an example of three adjacent concrete sleepers forming an independent, integrated track foundation. The ends of the three adjacent concrete sleepers are connected and fixed by the frame-type connecting mechanism, and are symmetrically installed on the left and right sides, forming an independent, integrated track foundation. The bottom support beam is a multi-segment bottom support beam 1b, composed of two segments spliced ​​together. Each segment spans between adjacent concrete sleepers. Each segment of the bottom support beam has a reinforcing rib 13, and a threaded post 12 is provided on both sides of the reinforcing rib 13. The bottom of the threaded post 12 is welded to the multi-segment bottom support beam 1b, and the side of the threaded post 12 is welded to the reinforcing rib 13. The upper barrier beam 2 is an integral structure upper barrier beam 2a, with its length spanning three adjacent concrete sleepers, and its inner groove surface is provided with bolt through holes corresponding to the threaded columns.

[0047] In the assembled state, the two multi-segment bottom support beams 1b are aligned with the center of the adjacent sleepers and placed on the bottom surface of the sleeper ends, with the threaded posts 12 facing upwards. The center of the integrated upper retaining beam 2a is aligned with the center of the middle sleeper and placed flat on the upper end surface of the sleeper. The four sets of threaded posts 12 are each aligned with the through holes passing through the inner groove surface of the upper retaining beam 2a, and then the connection is secured with nuts and washers. After the frame-type connecting mechanism at the ends of the left and right sleepers is installed and tightened, it forms a connecting whole that locks the sleeper ends together, forming an independent integral track foundation. Example 4:

[0048] As shown in Figure 13, a combined frame-type track foundation is provided. Adjacent concrete sleepers 3 are connected by a frame-type connecting mechanism. The frame-type connecting mechanism includes a bottom support frame 1 and an upper retaining beam 2. The bottom support frame 1 includes a bottom support beam, threaded posts 12, and reinforcing ribs 13. The bottom support beam is an integral structure, while the upper retaining beam 2 is composed of multiple segments spliced ​​together. The following explanation uses an example of three adjacent concrete sleepers forming an independent, integrated track foundation. The ends of the three adjacent concrete sleepers are connected and fixed by the frame-type connecting mechanism, and the left and right ends are symmetrically installed, forming an independent, integrated track foundation. The bottom support beam is an integral bottom support beam 1a, spanning the length of the three adjacent concrete sleepers. Two reinforcing ribs 13 are provided on the integral bottom support beam 1a, and threaded posts 12 are respectively provided on both sides of the two reinforcing ribs 13. The bottom of the threaded posts 12 is welded to the integral bottom support beam 1a, and the sides of the threaded posts 12 are welded to the reinforcing ribs 13. The upper barrier beam 2 is a multi-segment upper barrier beam 2b, which is composed of two segments spliced ​​together. Each segment has bolt through holes on its inner groove surface that correspond to the threaded column.

[0049] In the assembled state, the center of the base frame 1 is aligned with the center of the middle sleeper and placed on the lower surface of the sleeper end, with the threaded posts 12 facing upwards. The two multi-segment upper retaining beams 2b are sequentially installed flat on the upper end face of the sleeper. The four sets of threaded posts 12 are each aligned with the through holes passing through the inner groove surface of the upper retaining beams 2, and then the connection is secured with nuts and washers. After the frame-type connecting mechanism at the ends of the left and right sleepers is installed and tightened, it forms a connecting whole that locks the sleeper ends together, forming an independent integral track foundation.

[0050] As a variation of the above embodiments, the combined frame track foundation described in embodiments 1-4 can be used as the smallest overall track foundation unit. Based on the length of the overall track foundation, the integrated bottom support beam 1a, the multi-segment bottom support beam 1b, the integrated upper barrier beam 2a, and the multi-segment upper barrier beam 2b can be freely combined into different forms of frame connection mechanisms to connect adjacent concrete sleepers 3, thereby forming an independent overall track foundation.
