[0037] In the description of the embodiments of the present application, "multiple" and "several" mean more than two (including two), unless otherwise clearly and specifically defined.

[0038] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] According to some embodiments of the present application, referring to Figure 1 and Figure 2 shown. Figure 1 This is a schematic diagram of the structural cross-section of the rail powered rack system of the embodiment of the present application. Figure 2 It is a top view of the track power frame system of the embodiment of the present application. The track power frame system of the embodiment of the present application includes: two tool rails 1, multiple sleepers 2, a combined power frame mechanism 3 and a combined power frame mechanism 3, the two tool rails 1 are arranged in intervals and parallel to simulate the tracks on the railway main line; multiple sleepers 2 are arranged in intervals on the bottom surface of the two tool rails 1; the two tool rails 1 are clamped on the combined power frame mechanism 3, the combined power frame mechanism 3 includes a track adjustment component 31, an elevation adjustment component 32 and a curve superelevation adjustment component 33, and the combined power frame mechanism 3 is used to adjust the track parameters of the two tool rails 1; one end of the fixed support and tension mechanism 4 is connected to the combined power frame mechanism 3, and the other end is fixed to the bottom surface of the ballastless track bed.

[0040] Before laying the track on the railway main line, the tool rail 1 is first used to confirm its laying path. Specifically, the tool rail 1 is used to simulate the mold rail on the railway main line, and 60kg / m steel rails are usually used. The length of the tool rail 1 depends on the length of the track slab to be constructed. For example, if the ballastless track bed is cast continuously, a tool rail 1 with a length of 7.142m is generally used. The two tool rails 1 are fixed with a rack connection component and fish bolts.

[0041] The two tool rails 1 are clamped on the combined power frame mechanism 3, the track adjustment component 31 is used to adjust the position of the tool rail 1 along the extension direction of the track, the elevation adjustment component 32 is used to adjust the height of the tool rail 1, and the curve superelevation adjustment component 33 is used to adjust the curve superelevation of the tool rail 1; the fixed support and tension mechanism 4 provides a reliable support for the combined power frame mechanism 3, thereby laying a solid foundation for the track adjustment of the tool rail 1 and ensuring the overall stability during the adjustment process.

[0042] According to some embodiments of the present application, reference Figure 3 and Figure 4 As shown, Figure 3 is a schematic diagram of the structure of the combined power frame mechanism of an embodiment of the present application, Figure 4 The combined power frame mechanism 3 includes an inner support beam 34 and a wedge-shaped clamping plate 35. The inner support beam 34 is provided with two grooves 341. A wedge-shaped seat 342 is provided in each groove 341. Two tool rails 1 are clamped in the wedge-shaped seat 342. Two wedge-shaped clamping plates 35 are provided between each wedge-shaped seat 342. The two wedge-shaped clamping plates 35 are centrally symmetrically arranged. The tool rail 1 is arranged between the two wedge-shaped clamping plates 35. The length of the two wedge-shaped clamping plates 35 extending out of the groove 341 can be adjusted to adjust the distance between the two tool rails 1.

[0043] Specifically, the wedge seat 342 includes two wedge plates, which are centrally symmetrically arranged, and the two wedge clamping plates 35 are also centrally symmetrically arranged, and the wedge plates and wedge clamping plates 35 of the wedge seat 342 on each side are spliced ​​into a rectangle. "Adjusting the length of the two wedge clamping plates 35 extending out of the groove 341" refers to the length of the wedge clamping plates 35 extending out of the groove 341 in a direction perpendicular to the extension direction of the tool rail 1.

[0044] The distance between the two tool rails 1 is a fixed value, which is set to an inner gauge of 1435 mm when leaving the factory. Since the wedge plate of the wedge seat 342 on each side and the wedge clamping plate 35 are in inclined contact, when the wedge clamping plate 35 slides relative to the wedge plate of the wedge seat 342, the inclination angle of the tool rail 1 in the groove 341 changes, and the distance between the two tool rails 1 will change. Therefore, when fine-tuning the distance between the two tool rails 1, the distance between the two tool rails 1 can be increased or decreased by adjusting the length of the two wedge clamping plates 35 extending out of the groove 341.

[0045] According to some embodiments of the present application, reference Figure 3 and Figure 4 As shown, the rail adjustment assembly 31 includes a first motor 311, and an adjustment nut 343 is provided at one end of the inner support beam 34. The first motor 311 includes a rotating shaft 311a, and the rotating shaft 311a is inserted into the adjustment nut 343 of the inner support beam 34 to drive the inner support beam 34 to move along the extension direction of the inner support beam 34.

[0046] Specifically, the rotating shaft 311 a is provided with a thread that is threadedly connected to the adjusting nut 343 .

[0047] The first motor 311 provides power for the rotating shaft 311a, and the rotating shaft 311a is inserted into the adjusting nut 343 of the inner support beam 34. By rotating the rotating shaft 311a in the forward or reverse direction, the inner support beam 34 can be moved toward or away from the first motor 311, thereby adjusting the axial position of the tool rail 1 and realizing automatic adjustment of the tool rail 1 in the rail direction.

[0048] According to some embodiments of the present application, reference Figures 1 to 8 As shown, Figure 5 2 is a cross-sectional view and a top view of the outer joist of an embodiment of the present application. Figure 6 The front view and top view of the connecting socket of the embodiment of the present application are shown in FIG. Figure 7 The front view and top view of the connecting leg of the embodiment of the present application are shown in FIG. Figure 8 The schematic diagram of the structure of the elevation motor adjustment mechanism of the embodiment of the present application. The elevation adjustment assembly 32 includes an outer support beam 321, two connecting seats 322, two connecting legs 323 and two elevation motor adjustment mechanisms 324. The outer support beam 321 is arranged below the inner support beam 34, and the outer support beam 321 and the connecting seat 322 are connected by bolts; one end of the connecting leg 323 is connected to the elevation motor adjustment mechanism 324, and the other end is connected to the connecting seat 322; the elevation motor adjustment mechanism 324 is fixed to the bottom surface of the ballastless track bed, and the elevation motor adjustment mechanism 324 can be extended and retracted up and down to drive the connecting legs 323 to rise and fall.

[0049] Specifically, the outer joist 321 is arranged below the inner joist 34, and there is a certain gap between the outer joist 321 and the inner joist 34, so as to facilitate the rotation of the rotating shaft 311a, so that the inner joist 34 moves toward or away from the first motor 311. At the same time, bolt holes are arranged on the outer joist 321 and the connecting seat 322, and the outer joist 321 and the connecting seat 322 are connected by bolts. One end of the connecting leg 323 is connected to the elevation motor adjustment mechanism 324, and the other end is connected to the connecting seat 322. Since the elevation motor adjustment mechanism 324 can be extended and retracted up and down, it can drive the connecting leg 323 to move up and down. Since the outer joist 321 and the connecting seat 322 are connected, the outer joist 321 is driven to move up and down, and finally the effect of adjusting the elevation of the tool rail 1 is achieved.

[0050] The elevation motor adjustment mechanism 324 includes a second motor 324a, a first outer sleeve 324b and a first inner sleeve 324c. One end of the connecting leg 323 is sleeved on the first outer sleeve 324b. The second motor 324a is drivingly connected to the first inner sleeve 324c. The first outer sleeve 324b and the first inner sleeve 324c are threadedly connected. One end of the first inner sleeve 324c is sleeved in the first outer sleeve 324b. The other end of the first inner sleeve 324c is fixed to the bottom surface of the ballastless track bed. The second motor 324a drives the first inner sleeve 324c to rotate, so that the first inner sleeve 324c can be extended and retracted relative to the first outer sleeve 324b, thereby driving the connecting leg 323 to move up and down.

[0051] Specifically, "the second motor 324a is drivingly connected to the first inner sleeve 324c" means that the second motor 324a can drive the first inner sleeve 324c to rotate, but the second motor 324a and the first inner sleeve 324c are not in contact with each other, and a certain amount of extension and contraction of the first inner sleeve 324c relative to the first outer sleeve 324b needs to be provided.

[0052] The first outer sleeve 324b and the first inner sleeve 324c are threadedly connected, and the second motor 324a drives the first inner sleeve 324c to rotate, so that the first inner sleeve 324c can be extended and retracted relative to the first outer sleeve 324b, thereby realizing the lifting and lowering of the elevation motor adjustment mechanism 324, thereby driving the connecting leg 323 to lift and lower, and then driving the outer support beam 321 to move upward or downward, that is, the elevation of the tool rail 1 can be adjusted.

[0053] In addition, in other embodiments, the elevation motor adjustment mechanism 324 may also include a linear motor, a second outer sleeve and a second inner sleeve, one end of the connecting leg 323 is sleeved on the second outer sleeve, the linear motor is fixedly connected to the second outer sleeve, one end of the second inner sleeve is sleeved in the second outer sleeve and is connected to the linear motor drive, the linear motor drives the second inner sleeve to extend and retract relative to the second outer sleeve, driving the connecting leg 323 to move up and down, and the other end of the second inner sleeve is fixed to the bottom surface of the ballastless track bed.

[0054] The linear motor is drivingly connected to the second inner sleeve and provides driving force for the second inner sleeve to drive the second inner sleeve to extend and retract relative to the second outer sleeve, and can also realize the lifting and lowering of the elevation motor adjustment mechanism 324.

[0055] In other embodiments, reference Figures 1 to 8 The elevation motor adjustment mechanism 324 includes an adjusting screw rod 324d and a plurality of bearing seats 324e. Two bearing seats 324e are arranged on each elevation motor adjustment mechanism 324. The two bearing seats 324e are fixedly arranged on the first outer sleeve 324b at intervals. The connecting leg 323 includes a side nut 323a. The side nut 323a is arranged on one side of the connecting leg 323. Both ends of the adjusting screw rod 324d are rotatably connected to the bearing seats 324e. The adjusting screw rod 324d is inserted into the side nut 323a for manually adjusting the elevation.

[0056] Specifically, the side nut 323a is provided with a thread that cooperates with the adjusting screw rod 324d. And the above-mentioned "one end of the connecting leg 323 is sleeved on the first outer sliding sleeve 324b" wherein the connecting leg 323 can slide up and down relative to the first outer sliding sleeve 324b.

[0057] Two bearing seats 324e are provided on each elevation motor adjustment mechanism 324, and both ends of the adjustment screw rod 324d are rotatably connected to the bearing seats 324e; at the same time, the adjustment screw rod 324d is inserted into the side nut 323a of the connecting leg 323, and by rotating the adjustment screw rod 324d, the connecting leg 323 can move in the extension direction of the adjustment screw rod 324d and slide up and down relative to the first outer sleeve 324b, thereby realizing the manual adjustment function of the elevation, and used as a backup elevation adjustment mechanism. This manual elevation adjustment implementation method can be applied to both of the above two elevation motor adjustment mechanisms 324.

[0058] According to some embodiments of the present application, reference Fig. 9 and Fig.10 , Fig. 9 This is a cross-sectional view of the super-elevation section of the track power frame system of the embodiment of the present application. Fig.10Schematic diagram of the structure of the curve superelevation adjustment component of the embodiment of the present application. The curve superelevation adjustment component 33 includes a fixed seat 331, an adjustment seat 332, an adjustment nut pin 333 and an adjustment bolt 334. The connection seat 322 is provided with a connection hole 322a. The connection hole 322a includes a first connection hole 322a1 and a second connection hole 322a2 arranged at intervals. The diameter of the second connection hole 322a2 is larger than the diameter of the first connection hole 322a1. The adjustment seat 332 abuts against the connection leg 323. The connection leg 323 abuts against the second connection hole 322a1 on the connection seat 322. The connecting hole 322a2 is connected through the adjusting seat 332, and the adjusting nut pin 333 passes through the second connecting hole 322a2 and the connecting leg 323. The adjusting nut pin 333 is driven to move up and down in the second connecting hole 322a2 by screwing the adjusting bolt 334. The rotating shaft 331a of the fixed seat 331 passes through the first connecting hole 322a1 and the connecting leg 323, so that the connecting seat 322 can rotate relative to the rotating shaft 331a, and the adjusting seat 332 drives the connecting leg 323 to move up and down.

[0059] Specifically, the second connection hole 322a2 may be a circular hole, and its diameter is only required to be larger than the diameter of the first connection hole 322a1; in addition, the second connection hole 322a2 may be an oblong hole.

[0060] The rotating shaft 331a of the fixed seat 331 passes through the first connecting hole 322a1 and the connecting leg 323, thereby connecting the connecting seat 322 and the connecting leg 323; at the same time, the adjusting seat 332 abuts against the connecting leg 323, and the connecting leg 323 is connected to the second connecting hole 322a2 on the connecting seat 322 through the adjusting seat 332, and the adjusting nut pin 333 passes through the second connecting hole 322a2 and the connecting leg 323, and the adjusting nut pin 333 is driven to move up and down in the second connecting hole 322a2 by screwing the adjusting bolt 334, at this time, the connecting seat 322 can rotate relative to the rotating shaft 331a of the fixed seat 331, so that the adjusting seat 332 drives the connecting leg 323 to move up and down. The super-height adjustment of the curve is realized.

[0061] According to some embodiments of the present application, reference Fig. 9 The fixed support and tension mechanism 4 includes a connecting rod 41 and two telescopic rods 42. The telescopic rods 42 are arranged at both ends of the connecting rod 41 and can be extended relative to the connecting rod 41. The telescopic rod 42 at one end of the connecting rod 41 is connected to the elevation motor adjustment mechanism 324, and the telescopic rod 42 at the other end of the connecting rod 41 is connected to the bottom surface of the ballastless track bed. The connecting rod 41 is threadedly connected to the two telescopic rods 42. Rotating the connecting rod 41 can shorten or lengthen the two telescopic rods 42 synchronously.

[0062] The fixed support and tension mechanism 4 provides a reliable support for the combined power frame mechanism 3, thereby laying a solid foundation for the track adjustment of the tool rail 1 and ensuring the overall stability during the adjustment process. Since the fixed support and tension mechanism 4 needs to be fixed to the bottom surface of the ballastless track bed, and the bottom surface of the ballastless track bed is not necessarily in a completely flat state, in order to ensure that the elevation motor adjustment mechanism 324 is set vertically, it is necessary to adjust the extension length of the fixed support and tension mechanism 4. By threading the two ends of the connecting rod 41 with the two telescopic rods 42, rotating the connecting rod 41 can make the two telescopic rods 42 shorten or extend synchronously, thereby adjusting the extension length of the fixed support and tension mechanism 4 to ensure that the elevation motor adjustment mechanism 324 is set vertically.

[0063] This application is applicable to ballastless track racks with double-block sleepers, long-sleeper embedded sleepers and elastic support block sleepers, refer to Figure 2 and Fig.11 , Fig.11 It is a top view of the rail powered rack system in other embodiments of the present application.

[0064] The working principle and method of the track power rack system will be introduced in detail below.

[0065] First, support adjustment is performed. Since the fixed supporting and pulling mechanism 4 needs to be fixed to the bottom surface of the ballastless track bed, and the bottom surface of the ballastless track bed is not necessarily completely flat, in order to ensure that the elevation motor adjustment mechanism 324 is set vertically, one end of the fixed supporting and pulling mechanism 4 is connected to the elevation motor adjustment mechanism 324 of the combined power frame mechanism 3, and the two telescopic rods 42 of the fixed supporting and pulling mechanism 4 are synchronously shortened or extended by rotating the connecting rod 41 of the fixed supporting and pulling mechanism 4. After ensuring that the elevation motor adjustment mechanism 324 is in a vertical state, the other end is fixed to the bottom surface of the ballastless track bed.

[0066] Secondly, the track direction is adjusted. An adjustment nut 343 is provided at one end of the inner support beam 34. The rotating shaft 311a of the first motor 311 is inserted into the adjustment nut 343 of the inner support beam 34. By rotating the rotating shaft 311a in the forward or reverse direction, the inner support beam 34 can be moved in the direction close to or away from the first motor 311, thereby adjusting the axial position of the tool rail 1 and realizing the automatic adjustment of the tool rail 1 in the track direction. Since the wedge plate of the wedge seat 342 on each side and the wedge clamping plate 35 are in inclined contact, when the wedge clamping plate 35 slides relative to the wedge plate of the wedge seat 342, the inclination angle of the tool rail 1 in the groove 341 changes, and the distance between the two tool rails 1 will change. Therefore, when fine-tuning the distance between the two tool rails 1, the distance between the two tool rails 1 can be increased or decreased by adjusting the length of the two wedge clamping plates 35 extending out of the groove 341.

[0067] Then the elevation adjustment is performed. The elevation motor adjustment mechanism 324 includes a second motor 324a, a first outer sleeve 324b and a first inner sleeve 324c. The first outer sleeve 324b and the first inner sleeve 324c are threadedly connected.
