Description

Technical Field

[0001] This utility model relates to the field of ballastless track construction technology, and in particular to a ballastless track frame adjustment device. Background Technology

[0002] Ballastless track refers to a track structure that uses a monolithic foundation of concrete, asphalt mixture, etc., instead of loose gravel ballast. Compared to ballasted track, ballastless track avoids ballast splashing, offers better smoothness, stability, service life, durability, and requires less maintenance. Train speeds can reach over 350 km / h. Currently, ballastless track construction typically employs a frame-based construction method. The frame is reinforced and fine-tuned using specialized equipment and either top-mounted or supported. Specifically, after the track slab formwork is installed, the frame is installed and undergoes coarse and fine adjustments. Fine-tuning requires calibration using a total station or other specialized instruments. After fine-tuning, concrete is quickly poured until the entire track is fully formed.

[0003] In the relevant disclosed technology, two support mechanisms are arranged at intervals, with the two ends of the crossbeam respectively mounted on the top supports of the two support mechanisms. The two ends of the connecting rod are connected to the supports of the two support mechanisms. A rail support adjustment mechanism is set on the crossbeam to fix and adjust the rail. The support plate of the top support can be raised and lowered, thereby adjusting the height of the rail. The rail support adjustment mechanism can adjust the position of the rail. When using this equipment for adjustment, the height and lateral adjustment of the frame are entirely adjusted through mechanisms in different positions. During the adjustment process, it is difficult to ensure that the frame is quickly adjusted to the correct position, requiring multiple adjustments, resulting in low work efficiency.

[0026] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1-3 As shown, an embodiment of this utility model provides a ballastless track frame adjustment device, including a base 1, a first adjustment component, and a second adjustment component. The first adjustment component is arranged along a first direction, and the second adjustment component is arranged along a second direction. The first adjustment component is connected to the base 1, and the second adjustment component is connected to the first adjustment component. For example, the first direction is a vertical direction relative to the horizontal plane, and the second direction is a horizontal direction. During adjustment, the device is installed on the ground (track bed), i.e., the base 1 is fixed to the ground, and the bottom end of the first adjustment component is connected to the base 1. The second adjustment component is arranged laterally along the track. The first end of the second adjustment component is connected to the movable part of the first adjustment component, and the movable part of the second adjustment component is connected to a support seat 2 supporting the track frame. Thus, the support seat 2 has the aforementioned two degrees of freedom for adjustment, allowing direct adjustment of the corresponding support position of the track frame via the device.

[0030] During the actual adjustment of the prefabricated frame, because the frame has a certain length along the longitudinal direction of the track, it needs to be adjusted by multiple devices arranged along the longitudinal direction of the track on both sides to bring the frame to a preset posture. Each device adjusts a specific support position of the frame.

[0031] In this embodiment, the first adjustment assembly includes a first lead screw 3, a first movable seat 4, and a first drive unit. The first lead screw 3 is arranged along a first direction, and the first movable seat 4 is threadedly engaged with the first lead screw 3 so that the first movable seat 4 can move along the first direction when the first lead screw 3 rotates. The first end of the first lead screw 3 is rotatably connected to the base 1. The first drive unit includes a first drive motor 5 and a first transmission structure. The first transmission structure can be a gear or similar transmission method and is arranged inside the base 1. The first drive motor 5 is connected to the base 1, and the output end of the first drive motor 5 is connected to the first lead screw 3 via the first transmission structure, thereby driving the first lead screw 3 to rotate. Because the device requires fine-tuning of the frame, the first drive motor 5 needs to be a high-precision motor.

[0032] Meanwhile, to ensure the compactness and sealing of the structure, the first adjusting component in this embodiment is further provided with a first fixed seat 6. The first end of the first fixed seat 6 is fixedly connected to the base 1, and the first fixed seat 6 is configured as a cylindrical structure. The first lead screw 3 is located inside the first fixed seat 6, and the lower part of the first movable seat 4 is also located inside the first fixed seat 6, forming a sleeve with the first fixed seat 6. Therefore, the first fixed seat 6 can also provide a certain guiding and limiting effect on the first movable seat 4, so that the movement of the first movable seat 6 is more stable. It should also be noted that the first movable seat 6 itself also adopts a cylindrical structure, and the upper part of the first lead screw 3 is inserted into the first movable seat 4 and mates with the threaded hole of the first movable seat 4.

[0033] It is understood that the second adjustment component, support base 2, and supporting frame are all located on one side (inner side) of the first adjustment component. To make the first adjustment component more robust and maintain vertical accuracy, in this embodiment, a balance rod 7 is further provided on the other side (outer side) of the first adjustment component. The balance rod 7 can be in the form of a cylinder rod or a simple rod. One end of the balance rod 7 is fixed to the ground, and the other end is connected to the first fixed base 6 to make the torque on the first adjustment component more balanced. In one specific embodiment, the other end of the balance rod 7 is connected to the first fixed base 6 through a connecting seat 8. The connecting seat 8 is hinged to the end of the balance rod 7 to facilitate installation and adjustment.

[0034] In this embodiment, the second adjustment assembly includes a second lead screw 9, a second fixed base 10, and a second drive unit. The second fixed base 10 is fixedly connected to the first movable base 4. The second lead screw 9 is arranged laterally along the track. The support base 2 is threadedly engaged with the second lead screw 9 so that the support base 2 can move in a second direction when the second lead screw 9 rotates. The first end of the second lead screw 9 is rotatably connected to the second fixed base 10. The second drive unit includes a second drive motor 11 and a second transmission structure. The second transmission structure can also be a gear or similar transmission method. It is arranged inside the second fixed base 10. The second drive motor 11 is connected to the second fixed base 10, and the output end of the second drive motor 11 is connected to the second lead screw 9 via the second transmission structure, thereby driving the second lead screw 9 to rotate. Similarly, the second drive motor 11 needs to be a high-precision motor.

[0035] To ensure smoother rotation of the second lead screw 9, a bearing 12 is provided at a corresponding position on the second fixed base 10 in this embodiment. The bearing 12 supports the rotation of the second lead screw to improve stability and thus enhance adjustment accuracy. Similarly, a bearing 12 is also provided at a corresponding position on the first fixed base 6 or the base 1 to support the rotation of the first lead screw 3.

[0036] Therefore, the ballastless track frame adjustment device provided in this embodiment, through the setting of the first adjustment component and the second adjustment component, can adjust the support position of the support base 2 and the corresponding frame in two directions, such as vertical and horizontal adjustment of the track, so that the frame can be finely adjusted in place on site. The overall structure of the device is simple and can complete the adjustment in two directions simultaneously, simplifying the difficulty of on-site layout and facilitating on-site operation. Through the first drive motor 5 and the second drive motor 11, an automated adjustment method can be adopted, which improves the efficiency and accuracy of fine adjustment of the ballastless track frame, thereby improving the construction quality.

[0037] In other embodiments, the first and second adjustment components may not be driven by lead screws, but instead can be replaced by other types of linear adjustment components, as long as the adjustment accuracy meets the requirements. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not contradict each other, they should be considered within the scope of this specification.

[0038] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
