Detailed Implementation

[0072] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0073] Example 1

[0074] like Figures 1-5 As shown, this embodiment proposes an easily adjustable segmented splicing trough type continuous support track structure, including a concrete base 1, a trough sleeper 2, a splicing trough 3, a horizontal adjustment device 4, and an elastic constraint structure 5.

[0075] The trough sleepers 2 are fixedly installed on the concrete base 1. Specifically, two rows of trough sleepers 2 are symmetrically arranged on both sides of the center line of the concrete base 1. The splicing trough body 3 is installed on the trough sleepers 2. The splicing trough body 3 is provided with the elastic constraint structure 5, which covers the lower part of the rail 51 and is used to continuously support and lock the rail 51. The splicing trough body 3 is connected to the trough sleepers 2 through the horizontal adjustment device 4. The horizontal adjustment device 4 is used to adjust the longitudinal, lateral, and vertical positions of the splicing trough body 3, wherein the longitudinal direction is the track direction.

[0076] The concrete base 1 can be designed as a square plate or an arc shape depending on the line conditions to accommodate surface or underground lines. Depending on the line and construction requirements, the sleeper 2 can be designed as a plate-type sleeper or a wall-type sleeper, and can be constructed using either prefabrication or cast-in-place methods.

[0077] like Figure 3 As shown, multiple mounting slots 22 are spaced apart on both the left and right sides of the groove pillow 2, and the mounting slots 22 on both sides of the groove pillow 2 are symmetrically arranged, with the multiple mounting slots 22 being equally spaced. A positioning tube 21 is pre-embedded in the groove pillow 2, and the positioning tube 21 is set horizontally through the groove pillow 2. The positioning tube 21 is pre-embedded in the groove pillow 2 at the positions where the mounting slots 22 are opened, and the two ends of the positioning tube 21 are respectively connected to the mounting slots 22 on both sides of the groove pillow 2.

[0078] like Figure 4 As shown, the splicing groove 3 includes an adjusting groove 31 and a groove side plate 32. The upper part of the adjusting groove 31 is supported on the top surface of the groove pillow 2 and is located at the top of the mounting groove 22. The lower part of the adjusting groove 31 extends into the mounting groove 22. A through hole is provided on the adjusting groove 31 at a position corresponding to the positioning tube 21. Figure 5 As shown, the horizontal adjustment device 4 includes an adjusting plate 41, a positioning eccentric sleeve 42, an adjusting bolt 43, an adjusting nut 44, and an elastic washer 45. The positioning eccentric sleeve 42 is installed inside the positioning tube 21. The adjusting plate 41 is installed at the end of the positioning tube 21, located between the adjusting groove 31 and the groove support 2. The adjusting bolt 43 passes sequentially through the adjusting groove 31 on one side of the groove support 2, the adjusting plate 41, the positioning eccentric sleeve 42, and the adjusting groove 31 on the other side of the groove support 2, and is connected to the adjusting nut 44. The elastic washer 45 is installed between the adjusting bolt 43 and the adjusting groove 31.

[0079] With the above structure, multiple pairs of adjustment slots 31 will be formed on the top surface of the slot pillow 2. Each pair of adjustment slots 31 is installed on the top of the mounting slots 22 on the left and right sides of the slot pillow 2. The multiple pairs of adjustment slots 31 form an intermittent slot structure. Adjacent adjustment slots 31 arranged along the line direction are connected by slot side plates 32 to form a continuous slot structure. In this embodiment, the adjustment slots 31 and the slot side plates 32 are mechanically connected, such as by bolting, riveting, bonding, or keying, to facilitate installation and disassembly.

[0080] In this embodiment, the adjustment trough 31 is made of steel, and the side plate 32 of the trough is made of lightweight and low-cost board. Therefore, the splicing trough 3 is made of adjustment trough 31 and side plate 32 of different materials in sections, which effectively reduces the overall weight and cost of the splicing trough 3.

[0081] In this embodiment, the upper part of the adjusting groove 31 includes a horizontal support plate and a first vertical plate. The horizontal support plate is placed on the top surface of the groove pillow 2 and is located above the mounting groove 22. The first vertical plate is fixedly connected to the inner side of the horizontal support plate and is arranged perpendicular to the surface of the horizontal support plate. A rib plate connects the horizontal support plate and the first vertical plate. The first vertical plates on both sides of the groove pillow 2 are arranged opposite to each other, forming a groove between the two and the top surface of the groove pillow 2. The lower part of the adjusting groove 31 includes a second vertical plate. The second vertical plate is also fixedly connected to the inner side of the horizontal support plate, and the second vertical plate and the first vertical plate are located in the same vertical plane. A rib plate also connects the horizontal support plate and the second vertical plate. A through hole is provided on the second vertical plate for the adjusting bolt 43 to pass through.

[0082] Considering different line requirements and manufacturing processes, the adjustment tank 31 can be manufactured by integral casting or assembly welding.

[0083] The elastic constraint structure 5 includes an elastic damping material 52. A rail 51 is installed in the splicing groove 3 and filled with the elastic damping material 52. The elastic damping material 52 wraps around the lower part of the rail 51 and locks the rail 51 in place. The elastic damping material 52 can be any material that meets the requirements of the track structure, such as polyurethane or epoxy resin.

[0084] With the above structure, the vertical position of the positioning tube 21 can be adjusted to meet the requirements of the line for different splicing groove 3 heights, and the width of the groove pillow 2 can be adjusted to meet the requirements of the line for different splicing groove 3 widths.

[0085] The horizontal adjustment device 4 has longitudinal, lateral, and vertical adjustment functions. Unlike traditional fixed adjustment devices that are vertically fixed, this device adopts a horizontal placement. Through adjusting bolts 43, adjusting nuts 44, and elastic washers 45, and in conjunction with the installation of the positioning eccentric sleeve 42 and the positioning tube 21 pre-embedded on the slot support 2, the geometric state of the splicing slot 3 can be adjusted vertically, longitudinally, and laterally. The principle of adjusting the longitudinal, lateral, and vertical positions of the splicing slot 3 through the horizontal adjustment device 4 is as follows: Lateral adjustment of the splicing slot 3 is achieved by replacing adjusting pieces 41 of different thicknesses; longitudinal and vertical adjustment of the splicing slot 3 is achieved by replacing positioning eccentric sleeves 42 with different hole sizes installed in the positioning tube 21. For example, when the center of the positioning eccentric sleeve 42 shifts upward, the vertical position of the splicing slot 3 moves upward; when the center of the positioning eccentric sleeve 42 shifts along the line direction, the longitudinal position of the splicing slot 3 shifts. Vertical adjustment of the splicing groove 3 can also be achieved by installing elastic plates of different thicknesses between the splicing groove 3 and the groove support 2. By adjusting the splicing groove 3, the three-dimensional geometric state of the elastic constraint structure 5 within the groove can be adjusted, thereby meeting the needs of line operation and maintenance, and maximizing the adaptation to line construction errors.

[0086] The construction method for the aforementioned easily adjustable segmented splicing groove-type continuous support track structure includes the following steps:

[0087] S1: Trench sleeper construction;

[0088] After the concrete base 1 is constructed, the channel sleeper 2 is installed on the concrete base 1. Depending on the line design, if a cast-in-place wall-type channel sleeper is used, connecting steel bars need to be pre-embedded during the construction of the concrete base 1; if a precast slab-type channel sleeper is used, it can be directly installed and fixed on the concrete base 1.

[0089] S2: Rail welding;

[0090] The rail 51 is placed on the grooved sleeper 2. Starting from the beginning of the rail welding, special rail fixing fixtures are installed at each or every positioning tube 21. Then, the rail 51 is flash welded or aluminothermic welded to weld it into a long rail. After welding, the rail 51 is temporarily locked using the special rail fixing fixtures. This process is repeated to complete the welding of the rail 51. After the rail 51 is welded, stress release and surface treatment are performed on the rail 51 in situ.

[0091] S3: Installation of splicing groove;

[0092] Before installing the splicing trough 3, first remove the special fixing fixture for the rails. Based on the measured elevation, place an elastic plate of the corresponding thickness on the trough sleeper 2. Then, place a matching positioning eccentric sleeve 42 in the positioning tube 21. Next, install the adjusting trough 31, placing the adjusting plate 41 according to the designed trough width, and lock the splicing trough 3 in place using adjusting bolts 43 and adjusting nuts 44. After the two longitudinal adjusting troughs 31 are installed, the trough side plates 32 can be installed and fixed to the adjusting troughs 31 using a mechanical connection, thus forming a continuous and complete splicing trough 3.

[0093] S4: Construction of elastically constrained structures.

[0094] First, after cleaning the inside of the splicing groove 3, the rail 51 is geometrically adjusted and locked. Then, the elastic damping material 52 is poured to fill the remaining space inside the splicing groove 3, and the rail 51 is fixed in the U-shaped groove of the splicing groove 3, thus completing the construction of the entire track structure.

[0095] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
