Description

Technical Field

[0001] This application relates to the field of railway track construction technology, and in particular to a three-dimensional adjustment support device for track panel frames. Background Technology

[0002] Twin-block ballastless track, with its excellent stability, durability, and smoothness, has been widely used in high-speed railways and urban rail transit. During the construction of twin-block ballastless track, the positioning and adjustment of the track panel frame is a crucial process affecting the geometric accuracy of the track, and its adjustment accuracy directly relates to the final alignment quality of the track after subsequent concrete pouring.

[0003] Currently, the adjustment of the track panel frame is generally divided into two stages: coarse adjustment and fine adjustment. The coarse adjustment stage initially adjusts the track panel frame to a position close to the design, while the fine adjustment stage uses high-precision measuring instruments such as total stations and track inspection trolleys to finely adjust the track geometry parameters.

[0004] In existing track panel frame adjustment systems, the adjustment devices generally adopt a split structure design, meaning that the vertical adjustment bolts, lateral adjustment screws, and longitudinal positioning devices are set up independently. During fine-tuning operations, when operators need to switch from one adjustment direction to another, it is usually necessary to loosen the fastening devices of the previously adjusted direction. This can cause the track panel to slip or sink unexpectedly under the influence of gravity or structural stress.

[0005] Meanwhile, the force points of the split adjustment device are relatively dispersed, making it difficult to form a uniform and continuous support constraint on the track frame throughout the adjustment process. This can easily lead to the twisting and deformation of the track frame, which not only makes it difficult to meet the requirements of high-precision three-dimensional coordinate adjustment, but repeated corrections and adjustments may also damage the track structure.

[0006] Furthermore, existing adjustment devices lack stability and effective auxiliary fixing structures. For example, tray-type adjusters are prone to slippage when subjected to uneven force, leading to a decrease in track panel positioning accuracy and requiring frequent manual intervention during construction. During the concrete pouring stage, the exothermic expansion caused by hydration heat can easily cause the track panels to float, further affecting the final track forming quality. Summary of the Invention

[0007] In order to improve the problems of existing track panel frame adjustment devices being unable to maintain the continuity of track panel force during dynamic adjustment and being unable to suppress slippage and deformation, this application provides a three-dimensional adjustment support device for track panel frames.

[0008] The technical solution of the three-dimensional adjustment support device for track panel frame provided in this application is as follows: A three-dimensional adjustment support device for a track panel frame, comprising: A vertical support frame, with a base plate fixedly connected to its bottom; A three-dimensional adjustment mechanism is installed on the side of the vertical support frame, including a base, a bottom platform, a middle platform, and an upper platform stacked sequentially from bottom to top. The upper platform is raised and lowered on the middle platform and is provided with a rail interface for receiving the rail frame. The middle platform is slidably mounted on the bottom platform and is equipped with a longitudinal adjustment drive component. The bottom platform is slidably mounted on the base and is equipped with a transverse adjustment drive component. The upper platform is connected to the middle platform by a vertical adjustment bolt. A crossbeam is connected between the upper parts of two opposing vertical support frames, and the crossbeam is adjustablely suspended above the rail frame to limit the vertical displacement of the rail frame after adjustment and to connect the two vertical support frames.

[0009] Furthermore, the bottom of the middle platform is provided with a longitudinal groove, and the upper part of the bottom platform is provided with a longitudinal slide rail that cooperates with the longitudinal groove. One end of the longitudinal slide rail is provided with a longitudinal baffle fixed to the bottom platform. The longitudinal adjustment drive is mounted on the longitudinal baffle and is used to drive the central platform to generate longitudinal displacement along the longitudinal slide rail.

[0010] Furthermore, the bottom of the bottom platform is provided with a horizontal groove, and the upper part of the base is provided with a horizontal slide rail that cooperates with the horizontal groove. One end of the horizontal slide rail is provided with a horizontal baffle fixed to the base. The lateral adjustment drive is mounted on the lateral baffle and is used to drive the bottom platform to generate lateral displacement along the lateral slide rail.

[0011] Furthermore, a vertical adjustment drive is installed on the middle platform to drive the upper platform to produce vertical displacement. The longitudinal adjustment drive and / or the lateral adjustment drive and / or the vertical adjustment drive are adjustment bolts acting on the corresponding platform; or they are configured as linear drive components.

[0012] Furthermore, the upper platform is provided with a handle for disassembly and handling on the side where the rail interface is located.

[0013] Furthermore, the vertical support frame is composed of two parallel metal plates joined together and has a positioning cavity at the top for the end of the crossbeam to be inserted. The upper part of the vertical support frame is provided with a vertical adjustment structure for adjusting and locking the vertical position of the crossbeam.

[0014] Furthermore, the vertical adjustment structure includes: Positioning pin holes are provided at the corresponding positioning cavities of the vertical support frame, and multiple such holes are provided. A through-hole is provided at the end of the crossbeam; The positioning pin is adapted to both the positioning pin hole and the through pin hole, and is used to adjust the vertical position of the end of the crossbeam when inserted into positioning pin holes of different heights.

[0015] Furthermore, it also includes: A pin is rotatably mounted on the top of the vertical support frame, and several pins are provided. The locking bolt has a thread that passes through the pin, and its free end is used to press against the upper end face of the crossbeam.

[0016] Furthermore, the vertical support frame has a guide rail interface reserved on its side, and a reinforcing guide rail is embedded in multiple guide rail interfaces on the same side. The reinforcing guide rail is connected to the vertical support frame by bolts.

[0017] Furthermore, the base plate is fitted with anchors that extend to the bottom of the foundation.

[0018] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating the lateral adjustment drive, longitudinal adjustment drive, and vertical adjustment drive into the same three-dimensional adjustment mechanism, and making the adjustment structures in the three directions relatively independent and non-interfering with each other, the support constraints in the other two directions remain effective when adjusting the position in any direction. This creates a continuous support state for the track panel frame throughout the entire adjustment process, effectively eliminating the track panel slippage and sinking problems caused by the support gap when switching adjustment directions in traditional split-type adjustment devices, and significantly improving the accuracy and efficiency of three-dimensional adjustment. 2. Two opposing vertical support frames are connected by a crossbeam and suspended above the track panel frame. After the track panel frame is adjusted into place, the crossbeam applies vertical constraints to the track panel frame. This effectively prevents the track panel from floating due to the heat release and expansion of the concrete during the concrete pouring stage, and also pulls the two vertical support frames in the lateral direction. At the same time, in conjunction with the reinforcing guide rail, multiple vertical support frames are pulled in the longitudinal direction. The crossbeam and the reinforcing guide rail together form a spatial frame constraint in both the lateral and longitudinal directions, realizing the all-round stability of the track panel frame in three-dimensional space. This improves the problem of track panel frame deformation caused by the lack of auxiliary fixing structures in the existing technology. 3. Through the positioning cavity at the top of the vertical support frame, multiple positioning pin holes spaced along the height direction, through pin holes at the ends of the crossbeam, and the matching structure of positioning pins, the vertical installation position of the crossbeam can be quickly adjusted and reliably locked. This allows the support device to adapt to rail panel frames of different heights and different construction conditions. At the same time, after the crossbeam is locked, the connection rigidity between the crossbeam and the vertical support frame is enhanced by further tightening of vertical bolts and longitudinal bolts, taking into account both adjustment flexibility and structural stability. 4. The side-mounted design of the three-dimensional adjustment mechanism and the vertical support frame, along with the sliding fit and threaded drive between the various platforms within the three-dimensional adjustment mechanism, makes the entire adjustment process simple, intuitive, and easy to implement. Furthermore, the horizontal, vertical, and lateral adjustment bolts can all be operated with ordinary tools, eliminating the need for specialized equipment and reducing construction costs and operational barriers. Additionally, a handle is provided on the upper platform of the three-dimensional adjustment mechanism, facilitating quick disassembly, assembly, and transportation of the device, further enhancing the convenience of on-site construction. 5. The entire support device is fixedly connected to the bottom of the foundation by anchors on the base plate. At the same time, it is connected to the track bed formwork by reinforcing flanges and L-shaped reinforcing bolts on the reinforcing guide rail, forming a complete force transmission path from the bottom of the foundation to the track bed formwork. This significantly improves the anti-slip and anti-overturning capabilities of the support device under dynamic construction loads, effectively improving the problem of easy slippage of the existing tray-type adjuster when the force is uneven, and ensuring the long-term stability of the track panel positioning accuracy.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] Reference Figures 1-4 This application discloses a three-dimensional adjustment support device for a track panel frame, which includes a vertical support frame 51, a base plate 511, a three-dimensional adjustment mechanism, a crossbeam 52, and a reinforced guide rail 41.

[0024] The bottom of the vertical support frame 51 is fixedly connected to a base plate 511, which is used for fixed connection with the bottom of the foundation. Preferably, the base plate 511 is provided with an anchor 517 extending to the bottom of the foundation. The anchor 517 can be an extended bolt. By inserting the extended bolt into the bottom of the foundation, the entire device is reliably anchored, thereby effectively improving the overall stability of the device during subsequent adjustment operations and concrete pouring. In some embodiments, the anchor 517 can also be other forms of connecting components such as anchor bolts, expansion bolts, or pre-embedded connectors, as long as it can achieve a fixed connection between the base plate 511 and the bottom of the foundation.

[0025] Reference Figure 3 and Figure 4The three-dimensional adjustment mechanism is installed on the side of the vertical support frame 51, including a base 311, a bottom platform 321, a middle platform 331, and an upper platform 341 stacked sequentially from bottom to top. The base 311, as the lowest component of the three-dimensional adjustment mechanism, is directly or indirectly installed on the side of the vertical support frame 51. The bottom platform 321 is slidably disposed on the base 311 and equipped with a lateral adjustment drive component for driving the bottom platform 321 to slide laterally relative to the base 311. The middle platform 331 is slidably disposed on the bottom platform 321 and equipped with a longitudinal adjustment drive component for driving the middle platform 331 to slide longitudinally relative to the bottom platform 321. The upper platform 341 is vertically disposed on the middle platform 331. Specifically, the upper platform 341 is connected to the middle platform 331 through a vertical adjustment drive component, which enables the vertical lifting of the upper platform 341. The upper platform 341 is provided with a rail panel interface 343 for receiving the rail panel frame 1. The rail panel frame 1 can be fixedly connected to the upper platform 341 through the rail panel interface 343.

[0026] Reference Figure 2 and Figure 4 A crossbeam 52 connects the upper parts of two opposing vertical support frames 51, and is adjustablely suspended above the track panel frame 1. The crossbeam 52 has a dual function: firstly, spanning above the track panel frame 1, it applies a vertical constraint to the track panel frame 1 after it has been adjusted into position, limiting its vertical displacement and preventing the track panel from floating due to the thermal expansion of the concrete during subsequent concrete pouring; secondly, connecting the two opposing vertical support frames 51 provides lateral tension, enhancing the overall rigidity between the two vertical support frames 51 and further improving the structural stability of the entire support device.

[0027] Thus, the three-dimensional adjustment support device of this application, through the close combination of the vertical support frame 51, the three-dimensional adjustment mechanism and the crossbeam 52, forms a support system that can not only achieve precise adjustment of the track frame 1 in the horizontal, longitudinal and vertical directions, but also maintain the track frame 1 under stable force throughout the adjustment process.

[0028] In some embodiments, refer to Figure 3 and Figure 4The base 311 is fixedly connected to the mounting platform on the side of the vertical support frame 51 by bolts. A transverse groove 325 is provided at the lower part of the bottom platform 321, which engages with the transverse slide rail 313 on the upper part of the base 311, allowing the bottom platform 321 to slide relative to the base 311 along the transverse slide rail 313. A transverse baffle 312 fixed to the base 311 is provided at one end of the transverse slide rail 313, and a transverse adjustment drive is provided on the transverse baffle 312 to drive the bottom platform 321 to generate transverse displacement along the transverse slide rail 313. For example, the transverse adjustment drive is a transverse adjustment bolt 322, one end of which passes through the transverse baffle 312 and is threadedly connected to the bottom platform 321; when the transverse adjustment bolt 322 is rotated, the end of the transverse adjustment bolt 322 pushes the bottom platform 321 to slide along the transverse slide rail 313, thereby realizing the position adjustment of the three-dimensional adjustment mechanism in the transverse direction. In other embodiments, the lateral adjustment drive can also be configured as a linear drive, such as an electric push rod, a hydraulic cylinder or a pneumatic cylinder, as long as it can achieve lateral drive of the bottom platform 321.

[0029] In some embodiments, the upper part of the bottom platform 321 is provided with a longitudinal slide rail 324 extending in the longitudinal direction, and the bottom of the middle platform 331 is provided with a longitudinal groove 333. The longitudinal groove 333 cooperates with the longitudinal slide rail 324 on the upper part of the bottom platform 321, so that the middle platform 331 can slide relative to the bottom platform 321 along the longitudinal slide rail 324. One end of the longitudinal slide rail 324 is provided with a longitudinal baffle 323 fixed to the bottom platform 321, and a longitudinal adjustment drive is provided on the longitudinal baffle 323 for driving the middle platform 331 to generate longitudinal displacement along the longitudinal slide rail 324. Exemplarily, the longitudinal adjustment drive is a longitudinal adjustment bolt 332, one end of the longitudinal adjustment bolt 332 passes through the longitudinal baffle 323 and is threadedly connected to the middle platform 331; when the longitudinal adjustment bolt 332 is rotated, the end of the longitudinal adjustment bolt 332 pushes the middle platform 331 to slide along the longitudinal slide rail 324, thereby realizing the position adjustment of the three-dimensional adjustment mechanism in the longitudinal direction. In other embodiments, the longitudinal adjustment drive can also be configured as a linear drive, such as an electric actuator, hydraulic cylinder, or pneumatic cylinder.

[0030] In some embodiments, a vertical adjustment drive is installed on the middle platform 331 to drive the upper platform 341 to generate vertical displacement; specifically, the upper platform 341 is connected to the middle platform 331 via a vertical adjustment bolt 342. Preferably, the vertical adjustment bolt 342 is a thickened bolt with a hexagonal protrusion on its upper part to facilitate rotation by an operator using tools such as a wrench; the upper platform 341 is provided with a threaded hole or a threaded sleeve, and the vertical adjustment bolt 342 is rotatably mounted on the middle platform 331 and threadedly engaged with the threaded hole or threaded sleeve of the upper platform 341. When the vertical adjustment bolt 342 is rotated, the upper platform 341 rises or falls vertically under the drive of the threaded pair, thereby realizing the position adjustment of the three-dimensional adjustment mechanism in the vertical direction. In other embodiments, the vertical adjustment drive can also be configured as a linear drive, such as an electric push rod, a hydraulic cylinder, or a pneumatic cylinder.

[0031] In this embodiment, each of the above-mentioned adjustment driving components is set as an adjustment bolt. Thus, through the coordinated operation of the above-mentioned lateral adjustment bolt 322, longitudinal adjustment bolt 332 and vertical adjustment bolt 342, the operator can adjust the position of the track frame 1 in the lateral, longitudinal and vertical directions in sequence or alternately without loosening any fastening device, so that the track frame 1 always maintains an effective support and constraint state throughout the adjustment process.

[0032] In addition, refer to Figure 2 and Figure 3 On the side of the upper platform 341 where the rail interface 343 is set, a handle 344 is preferably provided. The handle 344 facilitates the quick operation of the operator when disassembling, assembling or moving the three-dimensional adjustment mechanism, which improves the convenience and efficiency of on-site construction.

[0033] In some embodiments, refer to Figure 2 and Figure 4 The vertical support frame 51 is composed of two parallel metal plates joined together. Preferably, both metal plates are hollow alloy plates. The hollow structure effectively reduces the overall weight of the vertical support frame 51 while ensuring that the support frame has sufficient structural strength. At the same time, the hollow design also facilitates observation, inspection and daily maintenance on the construction site.

[0034] The upper part of the vertical support frame 51 has a positioning cavity for inserting the end of the crossbeam 52. The end of the crossbeam 52 can be inserted into the positioning cavity. The upper part of the vertical support frame 51 is also provided with a vertical adjustment structure for adjusting and locking the vertical position of the crossbeam 52.

[0035] In some embodiments, the vertical adjustment structure includes a positioning pin hole 512, a through pin hole 521, and a positioning pin 513. The positioning pin holes 512 are formed at the corresponding positioning cavity locations on the vertical support frame 51, and multiple holes are provided and distributed in different height directions. The through pin holes 521 are formed through the end of the crossbeam 52. When the end of the crossbeam 52 is inserted into the positioning cavity, the through pin holes 521 align with the corresponding positioning pin holes 512. The positioning pins 513 are inserted into both the positioning pin holes 512 and the through pin holes 521. By inserting the positioning pins 513 into the positioning pin holes 512 at different heights, the vertical installation height of the end of the crossbeam 52 on the vertical support frame 51 can be adjusted, thereby allowing the crossbeam 52 to adapt to different heights of the track panel frame 1 or different construction conditions.

[0036] In some embodiments, a pin 514 may be rotatably mounted on the top of the vertical support frame 51, and several pins 514 are provided; a locking bolt 515 is threaded through the pin 514, and the free end of the locking bolt 515 is used to press against the upper end face of the crossbeam 52. By rotating the locking bolt 515 so that its free end presses downward against the upper end face of the crossbeam 52, the crossbeam 52 and the vertical support frame 51 can be further locked, enhancing the vertical constraint effect of the crossbeam 52 on the track frame 1 and preventing the crossbeam 52 from loosening during the concrete pouring process.

[0037] In other embodiments, reference is made to Figure 1 , Figure 2 and Figure 4 The vertical support frame 51 has a guide rail interface 516 pre-reserved on its side. Multiple guide rail interfaces 516 on the same side are fitted with reinforcing guide rails 41, which are bolted to the vertical support frame 51. The reinforcing guide rails 41 connect multiple vertical support frames 51 on the same side into a whole, effectively enhancing the overall rigidity and torsional resistance of the entire track panel frame 1 support system in the longitudinal direction. Furthermore, multiple reinforcing flanges 42 can be installed on the reinforcing guide rails 41. The reinforcing flanges 42 can be connected to the track bed template 2 via L-shaped reinforcing bolts 43, thereby achieving a reliable connection between the support device and the track bed template 2, further improving the overall stability of the entire device during the concrete pouring stage.

[0038] A typical construction method for a double-block ballastless track according to an embodiment of this application is as follows: S1. The vertical support frame 51 is installed on the base plate 511, and the base plate 511 is fixedly connected to the bottom of the foundation by anchors 517. Next, multiple vertical support frames 51 on the same side are connected by reinforcing guide rails 41. The reinforcing guide rails 41 are embedded in the guide rail interfaces 516 on the side of the vertical support frame 51, and the reinforcing guide rails 41 are fixedly connected to each vertical support frame 51 by high-strength bolts. Reinforcing flanges 42 can be pre-installed on the reinforcing guide rails 41. The reinforcing flanges 42 are connected to the track bed template 2 by L-shaped reinforcing bolts 43 to achieve a fixed connection between the support device and the track bed template 2.

[0039] S2. A three-dimensional adjustment mechanism is installed on the side of the vertical support frame 51, and the rail panel frame 1 is connected to the three-dimensional adjustment mechanism through the rail panel interface 343 on the upper part of the three-dimensional adjustment mechanism. The rail panel frame 1 can be fixedly connected to the rail panel interface 343 of the upper platform 341 by bolt connection, pin connection or other detachable connection methods.

[0040] S3. In the coarse adjustment stage of the track panel frame 1, the operator rotates the transverse adjustment bolt 322, longitudinal adjustment bolt 332, and vertical adjustment bolt 342 according to the measurement data to initially adjust the track panel frame 1 to a position close to the design. In the fine adjustment stage, high-precision measuring instruments such as a total station and a track inspection trolley are used to measure the track geometry parameters of the track panel frame 1 in real time, and the transverse adjustment bolt 322, longitudinal adjustment bolt 332, and vertical adjustment bolt 342 are finely adjusted according to the measurement results until the spatial position of the track panel frame 1 meets the design accuracy requirements.

[0041] It is important to note that during the adjustment process, the lateral adjustment bolt 322, longitudinal adjustment bolt 332, and vertical adjustment bolt 342 correspond to three mutually orthogonal adjustment directions, and each bolt is respectively mounted on the base 311, bottom platform 321, and middle platform 331 of the three-dimensional adjustment mechanism. These three components are structurally independent and functionally independent. When the operator adjusts the position in any direction, the locking status of the other two directions remains unaffected. That is, when adjusting the lateral position, the longitudinal and vertical support constraints remain effective; when adjusting the longitudinal position, the lateral and vertical support constraints remain effective; and when adjusting the vertical position, the lateral and longitudinal support constraints remain effective. Thus, throughout the entire adjustment process, the track panel frame 1 is always subject to support constraints in at least two directions, preventing any support gaps caused by switching adjustment directions.

[0042] S4. After the track panel frame 1 is adjusted into place, the crossbeam 52 is adjusted above the track panel frame 1 and locked, so that the crossbeam 52 applies a vertical clamping force to the track panel frame 1 to prevent the track panel from floating during the concrete pouring process.

[0043] S5. Construct the track bed concrete. During the concrete pouring and curing process, due to the combined action of the three-dimensional adjustment mechanism, vertical support frame 51, reinforced guide rail 41 and crossbeam 52, the track frame 1 is effectively constrained in the horizontal, longitudinal and vertical directions, which can resist various construction loads generated during the concrete pouring and curing process, and maintain the spatial positional stability of the track frame 1 until the concrete reaches the design strength.

[0044] In the above method, the operation of each adjusting bolt can be done manually or with auxiliary tools such as electric wrenches to improve adjustment efficiency. In cases where the track panel frame 1 requires frequent or large adjustments, the lateral, longitudinal, and / or vertical adjusting drive components can be configured as linear drive components such as electric push rods, hydraulic cylinders, or stepper motor-driven screw mechanisms. These components can share data with detection equipment such as total stations, and, in conjunction with controllers and displacement sensors, achieve automated or semi-automated precise adjustment.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
