DETAILED DESCRIPTION

[0072] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0073] Example 1

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

[0075] The trough sleeper 2 is fixedly mounted 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 mounted on the trough sleeper 2. The splicing trough body 3 is provided with the elastic constraint structure 5. The elastic constraint structure 5 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 sleeper 2 through the transverse adjustment device 4. The transverse adjustment device 4 is used to adjust the longitudinal, transverse and vertical positions of the splicing trough body 3, wherein the longitudinal direction is the line direction.

[0076] The concrete base 1 can be designed as a square plate or arc shape according to the line conditions to adapt to the ground line or underground line. According to the line and construction requirements, the trough pillow 2 can be designed as a plate trough pillow or a wall trough pillow, and can be prefabricated or cast-in-place respectively.

[0077] like Figure 3 As shown, a plurality of installation slots 22 are provided at intervals on both sides of the slot pillow 2, and the installation slots 22 on both sides of the slot pillow 2 are symmetrically arranged, and the plurality of installation slots 22 are provided at equal intervals. A positioning tube 21 is pre-buried on the slot pillow 2, and the positioning tube 21 is arranged to pass through the slot pillow 2 horizontally, and the positioning tube 21 is pre-buried at the position where the installation slot 22 is provided on the slot pillow 2, and the two ends of the positioning tube 21 are respectively connected to the installation slots 22 on both sides of the slot pillow 2.

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

[0079] Through the above structure, the top surface of the slot pillow 2 will be formed with multiple pairs of the adjustment slot bodies 31, and each pair of the adjustment slot bodies 31 is respectively installed on the top of the installation slots 22 on the left and right sides of the slot pillow 2. Multiple pairs of the adjustment slot bodies 31 form a discontinuous slot body structure, and the slot body side plates 32 are connected between two adjacent adjustment slot bodies 31 arranged along the line direction to form a continuous slot body structure. In this embodiment, the adjustment slot body 31 and the slot body side plates 32 are mechanically connected, such as bolting, riveting, bonding or key connection, to facilitate installation and disassembly.

[0080] In this embodiment, the adjustment tank body 31 adopts a steel structure, and the tank body side panels 32 adopt a lightweight and low-cost plate material. Therefore, the spliced ​​tank body 3 is formed by splicing the adjustment tank body 31 and the tank body side panels 32 made of different materials in sections, which effectively reduces the overall weight and cost of the spliced ​​tank body 3.

[0081] In this embodiment, the upper part of the adjustment slot body 31 includes a horizontal support plate and a vertical plate 1, the horizontal support plate is placed on the top surface of the slot pillow 2 and is located above the mounting slot 22, the vertical plate 1 is fixedly connected to the inner side of the horizontal support plate and is arranged perpendicular to the plate surface of the horizontal support plate, a rib plate is connected between the horizontal support plate and the vertical plate 1, the vertical plates 1 on both sides of the slot pillow 2 are arranged oppositely, and a slot body is formed between the two and the top surface of the slot pillow 2. The lower part of the adjustment slot body 31 includes a vertical plate 2, the vertical plate 2 is also fixedly connected to the inner side of the horizontal support plate, and the vertical plate 2 and the vertical plate 1 are located in the same vertical plane, the horizontal support plate and the vertical plate 2 are also connected with a rib plate, and a through hole is opened on the vertical plate 2 for the adjustment bolt 43 to pass through.

[0082] Taking into account different line requirements and manufacturing processes, the adjustment tank body 31 can be processed 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 slot 3 and filled with the elastic damping material 52. The elastic damping material 52 is wrapped around the lower part of the rail 51 to lock the rail 51. The elastic damping material 52 can be made of any material that meets the performance of the track structure, such as polyurethane, epoxy resin, etc.

[0084] By adopting the above structure, the vertical position of the positioning tube 21 can be adjusted to meet the line's requirements for different heights of the spliced ​​trough bodies 3 , and the width of the trough pillow 2 can be adjusted to meet the line's requirements for different widths of the spliced ​​trough bodies 3 .

[0085] The transverse adjustment device 4 has longitudinal, transverse and vertical adjustment functions. Different from the vertical fixing of the traditional fixed adjustment device, the device adopts a horizontal transverse mode. Through the adjustment bolt 43, the adjustment nut 44 and the elastic washer 45, the positioning eccentric sleeve 42 and the installation of the pre-buried positioning tube 21 on the slot pillow 2 can adjust the geometric state of the spliced ​​slot body 3 in the vertical, longitudinal and transverse directions. The principle of adjusting the longitudinal, transverse and vertical position of the spliced ​​slot body 3 by the transverse adjustment device 4 is as follows: the lateral adjustment of the spliced ​​slot body 3 is carried out by replacing the adjustment sheet 41 with different thickness specifications; the longitudinal and vertical adjustment of the spliced ​​slot body 3 is realized by replacing the positioning eccentric sleeve 42 with different hole specifications installed in the positioning tube 21. For example, when the center of the positioning eccentric sleeve 42 is offset upward, the vertical position of the spliced ​​slot body 3 moves upward, and when the center of the positioning eccentric sleeve 42 is offset along the line direction, the longitudinal position of the spliced ​​slot body 3 is offset. The vertical adjustment of the spliced ​​trough body 3 can also be achieved by installing elastic plates of different thicknesses between the spliced ​​trough body 3 and the trough pillow 2. By adjusting the spliced ​​trough body 3, the three-way geometric state adjustment of the elastic constraint structure 5 in the trough is driven, thereby meeting the line operation and maintenance requirements and adapting to the line construction error to the greatest extent.

[0086] Example 2

[0088] S1: trough and pillow construction;

[0089] After the construction of the concrete base 1 is completed, the trough sleeper 2 is installed on the concrete base 1. According to the line design, if a cast-in-place wall trough sleeper is used, it is necessary to pre-embed the connecting steel bars during the construction of the concrete base 1; if a prefabricated plate trough sleeper is used, it can be directly installed and fixed on the concrete base 1.

[0090] S2: Rail welding;

[0091] The rail 51 is placed on the slot sleeper 2, and starting from the starting point of the welded rail, a special fixing tool for the rail is installed at the positioning tubes 21 one by one or at regular intervals, and then the rail 51 is flash welded or thermite welded, and after the rail 51 is welded into a long rail strip, the rail 51 is temporarily locked by the special fixing tool for the rail, and the welding of the rail 51 is completed in this cycle. After the welding of the rail 51 is completed, the stress release and surface treatment of the rail 51 are performed in situ.

[0092] S3: splicing tank installation;

[0093] Before installing the spliced ​​trough 3, first remove the special fixing tool for the rail, place the elastic plate of the corresponding thickness specification on the trough sleeper 2 according to the measured elevation, then place the matching positioning eccentric sleeve 42 in the positioning tube 21, and then install the adjustment trough 31, place the adjustment sheet 41 according to the designed trough width, and lock the spliced ​​trough 3 with the adjustment bolt 43 and the adjustment nut 44. After the installation of the two adjustment troughs 31 in the longitudinal direction is completed, the trough side plate 32 can be installed, and it can be fixed to the adjustment trough 31 by mechanical connection, so as to form a full-length spliced ​​trough 3.

[0094] S4: Construction of elastically constrained structures.

[0095] First, clean the splicing trough 3, adjust the geometric state of the rail 51 and lock it, then pour the elastic damping material 52 to fill the remaining space in the splicing trough 3, fix the rail 51 in the U-shaped groove of the splicing trough 3, and complete the construction of the entire track structure.
