Description

Technical Field

[0001] This utility model relates to the field of rotating support technology, and more specifically, to a rotating support with permanent and temporary connections. Background Technology

[0002] Currently, when a new bridge needs to cross an existing railway line or highway, to avoid interfering with the normal operation of the existing railway line or highway, the new bridge is often constructed by rotating it alongside the existing line. Currently, bridge rotation construction mostly uses temporary rotating bearings (such as rotating pot bearings and rotating spherical bearings). After the rotation is completed, the temporary rotating bearings are cast together with the pier and cannot be reused, resulting in resource waste. After the bridge is completed by rotation, it no longer has the ability to rotate, failing to consider the bridge's rotation requirements. To address these issues, and to avoid the waste of bearings after rotation, meet the normal functional requirements of the bridge bearings after completion, and meet the future rotation requirements of the bridge, a combined permanent and temporary rotating bearing is proposed. Utility Model Content

[0003] The present invention aims to provide a combination of permanent and temporary rotating bearings to solve the problems in the existing bridge rotation construction, where the temporary rotating bearings are cast and fixed together with the piers after the rotation is completed, and the bearings cannot be used anymore, resulting in resource waste. Furthermore, after the bridge is rotated into a bridge, it no longer has the ability to rotate, which cannot meet the possible rotation requirements in the future.

[0004] This utility model is achieved using the following technical solution: This utility model provides a rotating support that combines permanent and temporary support, including an upper support plate, a spherical crown liner, an intermediate steel plate and a lower support plate; The upper support plate and the spherical crown liner form a planar friction pair, the spherical crown liner and the intermediate steel plate form a spherical friction pair, and the intermediate steel plate and the lower support plate form a planar rotational friction pair. Lateral limiting blocks are formed on both sides of the upper support plate, and the lateral limiting blocks are located on both sides of the middle steel plate. Temporary limiting blocks are detachably connected to both longitudinal sides of the upper support plate, and the temporary limiting blocks are located on both sides of the middle steel plate. A locking device is detachably connected between the intermediate steel plate and the lower support plate.

[0005] As a preferred technical solution: The temporary limiting block comes into contact with the intermediate steel plate.

[0006] As a preferred technical solution: A rotating pin is installed at the center of the lower support plate, and a rotating groove is opened at the bottom of the intermediate steel plate. One end of the rotating pin is placed in the rotating groove, and the intermediate steel plate and the lower support plate can rotate relative to each other.

[0007] As a preferred technical solution: A rotating sleeve is fitted around the rotating pin, and the rotating sleeve is located in the rotating groove.

[0008] As a preferred technical solution: The intermediate steel plate has multiple waist-shaped holes evenly spaced along its circumference.

[0009] As a preferred technical solution: The lower support plate is provided with a plurality of connecting holes evenly spaced apart. The connecting holes correspond to the waist-shaped holes. The locking member passes through the corresponding waist-shaped holes and the connecting holes to connect the intermediate steel plate to the lower support plate.

[0010] As a preferred technical solution: The temporary limiting blocks are symmetrically arranged on the upper support plate.

[0011] As a preferred technical solution: The temporary limiting block is connected to the upper support plate by a temporary connecting bolt; The locking component is a locking bolt.

[0012] As a preferred technical solution: A first planar sliding plate is provided between the upper support plate and the spherical crown liner plate. The first planar sliding plate is installed in the groove on the top surface of the spherical crown liner plate. The upper support plate and the first planar sliding plate form a planar friction pair. A spherical sliding plate is provided between the spherical crown liner and the intermediate steel plate. The spherical sliding plate is installed in a groove on the top surface of the intermediate steel plate, and the spherical crown liner and the spherical sliding plate form a spherical friction pair.

[0013] As a preferred technical solution: A second planar sliding plate and a stainless steel plate are installed between the intermediate steel plate and the lower support plate. The second planar sliding plate is installed in a groove on the bottom surface of the intermediate steel plate, and the stainless steel plate is fixed on the top surface of the lower support plate. The second planar sliding plate is in contact with the stainless steel plate, and the second planar sliding plate and the stainless steel plate form a horizontal rotating friction pair.

[0014] As a preferred technical solution: The upper support plate is connected to an upper anchoring assembly, and the lower support plate is connected to a lower anchoring assembly.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The permanent-temporary combined rotating support of this utility model uses temporary connecting bolts to connect temporary limiting blocks to the upper support plate to restrict the upper displacement of the support. The middle steel plate and the lower support plate form a planar rotational friction pair to realize the horizontal rotation function of the support. A rotating pin and rotating sleeve are set at the center of the support to fix the rotation center. After rotation, locking bolts are used to lock the middle steel plate and the lower support plate to fix the horizontal rotation surface. The temporary limiting blocks are removed to release the displacement of the support in the direction of displacement movement, which meets the displacement requirements after the bridge is completed. This realizes the transformation of the support from a temporary rotating state to a permanent support state, avoids the waste of the rotating support after the bridge rotates, and reduces the project cost. When the bridge needs to rotate, temporary connecting bolts are used to connect temporary limiting blocks to the upper support plate to fix the upper structure of the support. The locking bolts between the middle steel plate and the lower support plate are removed to release the horizontal rotation, and the support restores the bridge rotation function, which can meet the bridge rotation requirements.

Detailed Implementation

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

[0023] Example 1 like Figures 1-4 As shown, this embodiment proposes a permanent and temporary combined rotating support, which includes an upper support plate 1, a spherical crown liner plate 4, an intermediate steel plate 6 and a lower support plate 10 arranged from top to bottom.

[0024] The upper support plate 1 and the spherical crown liner 4 form a planar friction pair, the spherical crown liner 4 and the intermediate steel plate 6 form a spherical friction pair, and the intermediate steel plate 6 and the lower support plate 10 form a planar rotational friction pair.

[0025] Lateral limiting blocks 20 are formed on both sides of the upper support plate 1, and the lateral limiting blocks 20 are located on both sides of the intermediate steel plate 6. The lateral limiting blocks 20 are used to limit the displacement of the support in the support limiting direction. When the support is in normal use, the lateral limiting blocks 20 are used to limit the displacement of the support in the transverse direction of the bridge.

[0026] Temporary limiting blocks 17 are detachably connected to both longitudinal sides of the upper support plate 1, and the temporary limiting blocks 17 are located on both sides of the intermediate steel plate 6. The temporary limiting blocks 17 are used to temporarily restrict the displacement of the support in the direction of displacement movement, so as to facilitate the rotation of the bridge.

[0027] A locking element is detachably connected between the intermediate steel plate 6 and the lower support plate 10.

[0028] Since the temporary limiting block 17 and the locking member are detachable, they can be installed or removed as needed.

[0029] When bridge rotation is required, the temporary limiting block 17 is installed on the upper support plate 1. The temporary limiting block 17 is located on both sides of the intermediate steel plate 6, restricting the displacement of the intermediate steel plate 6 in the direction of displacement. At this time, the locking member is not installed, and the intermediate steel plate 6 and the lower support plate 10 can rotate relative to each other in the plane, meeting the needs of the support for bridge rotation construction and realizing the support rotation function. Moreover, this utility model uses the temporary limiting block 17 to fix the upper part of the support during rotation, so that the bridge rotation occurs on the horizontal rotation surface of the lower part of the support, ensuring the stability of the upper structure and ensuring the safety and stability of the bridge rotation process.

[0030] After the rotation is completed, the locking member is connected between the intermediate steel plate 6 and the lower support plate 10, and the intermediate steel plate 6 and the lower support plate 10 are locked together to fix the horizontal rotation friction pair, so that the lower part of the support is fixed. In this way, it can resist the horizontal load during the normal use of the support in the later stage; the temporary limiting block 17 is removed to release the restriction on the displacement direction of the support after the bridge is completed.

[0031] After the bridge is completed, the rotating support of this utility model meets the normal displacement and rotation requirements of the support through the planar friction pair and the spherical friction pair. The locking member locks the lower rotating surface of the support after rotation. After locking the horizontal rotating friction pair, the support meets the requirement of resisting horizontal force. The support can be used as a permanent support, avoiding waste of the support after rotation.

[0032] When there is a need for bridge rotation, the temporary limiting block 17 is installed on the upper support plate 1 to restrict the displacement of the intermediate steel plate 6 in the direction of displacement. The locking device is removed to release the horizontal rotational friction pair formed by the intermediate steel plate 6 and the lower support plate 10, so that the support can regain its rotational ability. Then, the rotational construction is carried out according to the rotational construction plan.

[0033] Therefore, the rotating support of this utility model can continue to be used after the rotation is completed, avoiding the waste of the rotating support after the bridge is rotated and reducing the project cost; moreover, the support can restore the horizontal rotation function after the bridge is completed, restore the bridge's rotation capacity, and meet the bridge's rotation requirements.

[0034] Preferably, the temporary limiting block 17 is in contact with the intermediate steel plate 6.

[0035] Preferably, the temporary limiting block 17 can be connected to the upper support plate 1 via, but is not limited to, a temporary connecting bolt 16. Before rotation, the temporary limiting block 17 is connected to the upper support plate 1 using the temporary connecting bolt 16. The temporary limiting block 17 fixes and limits the intermediate steel plate 6 to prevent displacement of the upper part of the support. The rotation function of the support is achieved by the planar rotational friction pair formed by the lower support plate 10 and the intermediate steel plate 6. After rotation, the temporary connecting bolt 16 and the temporary limiting block 17 are removed to release the displacement in the direction of the support's movement, so that the support meets the functional requirements of displacement and rotation after the bridge is completed. The permanent and temporary combined rotating support of this utility model is no longer cast together with the pier and continues to be used as a permanent support.

[0036] Preferably, the locking element can be, but is not limited to, a locking bolt 18. After rotation, the locking bolt 18 is used to lock the intermediate steel plate 6 to the lower support plate 10 to fix the rotation surface of the lower part of the support. When rotation is required, the temporary connecting bolt 16 is used to connect the temporary limiting block 17 to the upper support plate 1, which again fixes and limits the intermediate steel plate 6, restricting the displacement of the upper part of the support. The locking bolt 18 connecting the intermediate steel plate 6 and the lower support plate 10 is then removed to release the horizontal rotation of the lower part of the support and meet the rotation requirement.

[0037] Preferably, a rotating pin 9 is installed at the center of the lower support plate 10, and a rotating groove is provided at the bottom of the intermediate steel plate 6. One end of the rotating pin 9 is placed in the rotating groove, and the intermediate steel plate 6 and the lower support plate 10 can rotate relative to each other.

[0038] Preferably, a rotating sleeve 8 is fitted around the outside of the rotating pin 9, the rotating sleeve 8 is located in the rotating groove, and the rotating sleeve 8 is located between the rotating pin 9 and the intermediate steel plate 6. During the rotation process, the upper part of the support rotates around the rotating pin 9 and the rotating sleeve 8 located at the center of the support.

[0039] Preferably, a first planar sliding plate 2 is provided between the upper support plate 1 and the spherical crown liner 4. The first planar sliding plate 2 is installed in the groove on the top surface of the spherical crown liner 4, and the upper support plate 1 and the first planar sliding plate 2 form a planar friction pair. A spherical sliding plate 5 is provided between the spherical crown liner 4 and the intermediate steel plate 6. The spherical sliding plate 5 is installed in the groove on the top surface of the intermediate steel plate 6. The spherical crown liner 4 and the spherical sliding plate 5 form a spherical friction pair. A second planar sliding plate 7 and a stainless steel plate 19 are installed between the intermediate steel plate 6 and the lower support plate 10. The second planar sliding plate 7 is installed in a groove on the bottom surface of the intermediate steel plate 6, and the stainless steel plate 19 is fixed to the top surface of the lower support plate 10. The second planar sliding plate 7 and the stainless steel plate 19 are in contact, forming a horizontal rotational friction pair. The contact surface between the second planar sliding plate 7 and the stainless steel plate 19 serves as a horizontal rotational surface.

[0040] Preferably, a sealing ring 3 is also provided between the upper support plate 1 and the spherical crown liner plate 4.

[0041] Preferably, the lower support plate 10 is connected to the pre-embedded steel plate 11.

[0042] Preferably, the upper support plate 1 is connected to an upper anchoring assembly 15, the upper anchoring assembly 15 including an upper anchoring bolt 14, and the lower support plate 10 is connected to a lower anchoring assembly 12, the lower anchoring assembly 12 including a lower anchoring bolt 13.

[0043] Example 2 The difference between this embodiment and Embodiment 1 is that: like Figure 5 As shown, the intermediate steel plate 6 has a plurality of waist-shaped holes 601 evenly spaced on its circumference, and the lower support plate 10 has a plurality of connecting holes evenly spaced on its circumference. The connecting holes correspond to the waist-shaped holes 601. The locking bolts 18 are set through the corresponding waist-shaped holes 601 and the connecting holes, thereby connecting the intermediate steel plate 6 and the lower support plate 10.

[0044] This design not only adapts to various rotation angles during bridge rotation construction, ensuring that the waist-shaped hole 601 of the intermediate steel plate 6 easily aligns with the connection hole of the lower support plate 10 after rotation, and the two can be connected by the locking bolt 18, thus effectively locking the intermediate steel plate 6 and the lower support plate 10 after bridge rotation, solving the problem of the intermediate steel plate 6 and the lower support plate 10 not being effectively locked after bridge rotation; but also the design of the waist-shaped hole 601 has a certain assembly allowance, allowing the locking bolt 18 to smoothly lock the intermediate steel plate 6 and the lower support plate 10. After the intermediate steel plate 6 and the lower support plate 10 are locked, they can provide the ability to resist and transmit horizontal forces.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
