Description

Technical Field

[0001] This utility model relates to the field of railway engineering technology, and in particular to an adjustable support for railways. Background Technology

[0002] As a key component connecting the superstructure and substructure of railway bridges, railway bearings have the core function of stably transmitting the huge vertical and horizontal loads from trains and track structures, ensuring the safety and stability of the bridge structure. During the construction and long-term operation and maintenance of railways, there are extremely high requirements for the installation accuracy of the bearings.

[0003] To address the needs of construction errors, uneven foundation settlement, and subsequent line maintenance and adjustments, adjustable bearings have emerged. Existing adjustable bearings typically use the addition or removal of shims or a simple screw mechanism to adjust the height. However, adjusting by adding or removing shims is cumbersome, requiring the upper structure to be lifted, which is not only time-consuming and labor-intensive, but also the adjustment accuracy is limited by the thickness of the shims, making it difficult to achieve continuous and precise adjustments.

[0004] More importantly, the railway operating environment is extremely harsh. When trains pass by at high speeds, they generate strong and continuous vibrations and impacts. For many existing adjustable bearings, the locking structure after adjustment is often not stable enough. Under long-term dynamic loads, these locking components are prone to the accumulation of small displacements, loosening, or even failure, resulting in slow and imperceptible changes in bearing height. This height instability will directly damage the smoothness of the track, aggravate the wear of the wheel-rail system, and pose a serious potential threat to traffic safety.

[0005] Therefore, this utility model proposes an adjustable support for railways to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an adjustable support for railways, aiming to improve the problems of cumbersome adjustment process, low precision, and low reliability of locking structure under long-term vibration in the existing adjustable supports for railways.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable support for railways, comprising: an upper support, a lower support, a support column connecting the upper support and the lower support, an adjustment component, and a locking component.

[0008] The adjustment assembly includes a fixed frame and an adjustment plate slidably disposed within the fixed frame, and the adjustment plate is fixedly connected to the support column.

[0009] The locking assembly includes a locking bolt and a nut; both the fixed frame and the adjusting plate have corresponding locking holes, and the locking bolt can be inserted into the corresponding locking holes and locked by the nut, thereby locking the adjusting plate relative to the fixed frame.

[0010] Preferably, the adjustment component further includes a protrusion disposed on the inner wall of the fixed frame for guiding and limiting the sliding of the adjustment plate.

[0011] Preferably, the adjustment assembly further includes a first spring and a second spring, which are disposed between the fixed frame and the adjustment plate to provide cushioning for the movement of the adjustment plate.

[0012] Furthermore, the first spring is located above the adjusting plate, and the second spring is located below the adjusting plate.

[0013] Preferably, the adjustable railway support further includes an upper anchor bolt for connecting the upper support to an external structure.

[0014] Preferably, the adjustable railway support further includes a lower anchor bolt for connecting the lower support to an external structure.

[0015] Preferably, the adjustable railway bearing further includes a support pile connected to the bottom of the lower bearing to enhance the overall support strength.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, by setting an adjustment plate that can slide within the fixed frame and using locking bolts to lock the adjustment plate through the corresponding locking holes on the fixed frame, the problem of the difficulty in accurately adjusting the height of railway supports and the easy loosening of the locking structure under vibration in the prior art is solved.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4 The present invention provides an embodiment of an adjustable railway support, which aims to solve the problems of inconvenient height adjustment and unstable locking structure of existing railway supports.

[0027] The adjustable railway support includes an upper support 1, a lower support 2, and a support column 3 connecting the upper support 1 and the lower support 2. The upper support 1 and the lower support 2 constitute the upper and lower support structure of the device. The support column 3 plays the main role of connection and load bearing. The core part of the adjustable railway support also includes an adjustment component 4 for height adjustment and a locking component 5 for fixing after adjustment.

[0028] The adjustment assembly 4 includes a fixed frame 401 and an adjustment plate 402. The adjustment plate 402 is slidably disposed inside the fixed frame 401 and is fixedly connected to the support column 3. The lifting and lowering movement of the support column 3 can directly drive the adjustment plate 402 to lift and lower synchronously within the fixed frame 401. To ensure the smoothness and accuracy of the adjustment process, a protrusion 403 is provided on the inner wall of the fixed frame 401. The protrusion 403 cooperates with the edge of the adjustment plate 402 to guide and limit the sliding of the adjustment plate 402 and prevent it from tilting during movement.

[0029] The adjustment assembly 4 also includes a first spring 404 and a second spring 405. The first spring 404 is located above the adjustment plate 402, and the second spring 405 is located below the adjustment plate 402. Both the first spring 404 and the second spring 405 are located between the fixed frame 401 and the adjustment plate 402, providing buffering and restoring elasticity for the movement of the adjustment plate 402.

[0030] The locking assembly 5 includes a locking bolt 501 and a nut 503 that cooperates with it. Both the fixed frame 401 and the adjusting plate 402 have multiple locking holes 502 that are distributed along the height direction and correspond to each other. When the adjusting plate 402 slides to a predetermined height, the locking holes 502 on it are aligned with the locking holes 502 on the fixed frame 401. At this time, the locking bolt 501 is inserted into the aligned locking holes 502 and locked from the other end by the nut 503. Through the fastening action of the bolt and the nut, the adjusting plate 402 is finally firmly locked in the designated position in the fixed frame 401.

[0031] The locking assembly 5 includes a locking bolt 501 and a nut 503, which are key components for achieving final fixation. In cooperation with the locking assembly 5, the fixing frame 401 and the adjusting plate 402 are provided with a plurality of locking holes 502 arranged along their sliding direction.

[0032] When adjusting the height, the adjusting plate 402 slides inside the fixed frame 401. When the height is adjusted to a certain target height, a certain locking hole 502 on the adjusting plate 402 is aligned with a certain locking hole 502 on the fixed frame 401.

[0033] The locking bolts 501 are passed through the locking holes 502 of the aligned fixed frame 401 and the locking holes 502 of the adjusting plate 402 in sequence. Then, the nuts 503 are threadedly connected to the locking bolts 501 and tightened. This structure, in which the locking bolts 501 and nuts 503 are passed through and locked in the corresponding locking holes 502, makes a firm rigid connection between the adjusting plate 402 and the fixed frame 401, thereby ensuring that the height of the support remains stable when subjected to the huge impact and vibration generated by railway operation.

[0034] To ensure a stable connection between the entire support device and the external environment, the adjustable railway support also includes an upper anchor bolt 6, a lower anchor bolt 7, and a support pile 8. The upper anchor bolt 6 is used to connect the upper support 1 to the external structure, and the lower anchor bolt 7 is used to connect the lower support 2 to the external structure. The support pile 8 is connected to the bottom of the lower support 2 and is used to transfer the load of the entire support to a deeper foundation, further enhancing the support strength and stability of the overall device.

[0035] In order to provide precise guidance and limit for the sliding process of the adjustment plate 402, the adjustment assembly 4 also includes a protrusion 403. The protrusion 403 is disposed on the inner wall of the fixed frame 401 and slides in contact with the side edge of the adjustment plate 402 to ensure that the adjustment plate 402 moves smoothly along the preset trajectory.

[0036] To make the height adjustment process smoother and have a buffering effect, the adjustment component 4 also includes a first spring 404 and a second spring 405, both of which are disposed between the fixed frame 401 and the adjustment plate 402. More specifically, the first spring 404 is disposed above the adjustment plate 402, and the second spring 405 is disposed below the adjustment plate 402. The two springs provide bidirectional buffering and restoring elastic force for the movement of the adjustment plate 402 through their own elastic deformation.

[0037] In order to reliably install the entire support in the application environment, the railway adjustable support also includes an upper anchor bolt 6 for connecting the upper support 1 to the external structure and a lower anchor bolt 7 for connecting the lower support 2 to the external structure. The fastening action of the upper anchor bolt 6 and the lower anchor bolt 7 ensures the stability of the support body and the external connection structure.

[0038] The adjustable bearing for railway also includes a support pile 8, which is connected to the bottom of the lower bearing 2 to effectively transfer the load borne by the bearing to the foundation structure.

[0039] Working principle: In the initial installation and support state, the whole device forms an upper and lower support plane through the upper support 1 and the lower support 2. The support column 3 acts as a load-bearing component to transfer the load. The upper anchor bolt 6 and the lower anchor bolt 7 firmly connect the upper support 1 and the lower support 2 to the railway facilities and foundation structure, respectively. The support pile 8 at the bottom further enhances the support strength and stability of the entire support.

[0040] When the height of the support needs to be adjusted to fit the railway facilities, first loosen the nut 503 of the locking assembly 5 and remove the locking bolt 501 to release the lock on the adjusting plate 402; then, by applying external force, the support column 3 is raised and lowered. Since the adjusting plate 402 is fixedly connected to the support column 3, the adjusting plate 402 slides up and down synchronously inside the fixed frame 401; during this sliding process, the protrusion 403 on the inner wall of the fixed frame 401 guides and limits the movement path of the adjusting plate 402, ensuring its straightness and stability.

[0041] Meanwhile, when the adjusting plate 402 moves, the first spring 404 and the second spring 405 above or below it will undergo corresponding elastic deformation. This deformation process provides effective buffering for the movement of the adjusting plate 402, making the entire height adjustment process more stable, smooth and easy to control, avoiding impact and jamming.

[0042] After the adjusting plate 402 moves to the target height position, its locking hole 502 is aligned with the corresponding locking hole 502 on the fixed frame 401. The locking bolt 501 is inserted into the aligned locking hole 502 and locked with the nut 503, thereby establishing a firm mechanical lock between the adjusting plate 402 and the fixed frame 401, effectively resisting the vibration and impact brought by railway operation and preventing any change in height. Through the cooperation of the adjusting component 4 and the locking component 5, this utility model solves the problems of complex adjustment and unreliable locking of existing supports.
