Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of building engineering technology, and more specifically, to a bridge rotation device. Background Technology

[0002] Bridge rotation construction technology involves fabricating the bridge structure in a location other than the design axis, and then rotating it into place. This transforms high-altitude operations into onshore or near-ground operations, greatly reducing construction difficulty and risk. Over time, this technology has evolved into vertical rotation, horizontal rotation, and a combination of both methods, with horizontal rotation being the most widely used.

[0003] Early bridge rotation construction technology had many limitations. The rotation devices were rudimentary, the power systems were simple, and they could not meet the needs of large bridge rotation. Furthermore, precision control was difficult, making it hard to ensure accurate docking after the bridge was rotated. As the scale of bridge construction expands, the span increases, and the structural forms become more complex and diverse, higher requirements are placed on the performance, precision, and stability of rotation construction technology and devices. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a bridge rotation device, which solves the technical problems of the existing bridge rotation construction technology, such as the rudimentary rotation device, the single power system, the difficulty in meeting the requirements of large bridge rotation, and the difficulty in precision control, making it difficult to ensure accurate docking after bridge rotation.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a bridge rotation device, comprising:

[0006] A drive ring, wherein a clamping ring is provided on the outside of the drive ring;

[0007] A drive rotation assembly is disposed inside the clamping ring;

[0008] A splicing fastening assembly, wherein the splicing fastening assembly is disposed on the clamping ring;

[0009] The drive rotation assembly includes a drive cavity, inside which is a mounting shaft. A flipping block is fitted on the mounting shaft, and a push rod is provided on the flipping block. A push block is provided at the end of the push rod. Force teeth are provided on the outer wall of the drive ring, and the push block is in contact with the force teeth.

[0010] As a further technical solution, the flipping block has a connecting hole, the inside of the connecting hole is provided with a stepped groove, and a torsion steel spring is provided in the stepped groove. The top of the torsion steel spring is fixedly connected to the driving cavity.

[0011] As a further technical solution, the splicing fastening assembly includes a connecting piece, which is disposed on the side wall of the clamping ring. The connecting piece is provided with a positioning groove and a clamping buckle. The side wall of the clamping buckle is provided with a clamping piece, and the clamping piece and the connecting piece are fixedly clamped together.

[0012] As a further technical solution, the clamping ring is composed of two semi-circular structures spliced ​​together, and the clamping ring is provided with a connecting buckle, and the clamping ring is connected by the connecting buckle pin.

[0013] As a further technical solution, the inner sidewall of the clamping ring is provided with fitting teeth, which are fixedly fitted with the bridge column.

[0014] As a further technical solution, the force-bearing teeth are ratchet-shaped oblique teeth, and the number of pushing blocks is several, with multiple pushing blocks evenly distributed on the inner sidewall of the clamping ring.

[0015] As a further technical solution, the clamping buckle has an I-shaped structure, and the inside of the clamping buckle is provided with a clamping anti-slip pad.

[0016] As a further technical solution, there are two stepped grooves, which are located at the upper and lower ends of the connecting hole, respectively, and the torsion steel spring is installed inside each of the two stepped grooves.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] In this disclosure, the push rod uses a hydraulic cylinder as its power source, providing stable and controllable thrust. Combined with the ratchet-shaped oblique force-bearing teeth on the outer side of the drive ring, the push block applies force along the direction of the oblique teeth, creating a unidirectional driving effect and avoiding power waste. Multiple push blocks are evenly distributed inside the clamping ring, and their synchronized force application makes the drive ring rotate more smoothly, ensuring uniform power transmission during bridge rotation and reducing swaying and impact. The connecting holes on the flipping block are equipped with stepped grooves and torsion springs. When the push block pushes the force-bearing teeth, the torsion spring is compressed and stores elastic potential energy, which can buffer the rigid force during the pushing process, preventing damage to the drive components due to instantaneous overload. When the hydraulic cylinder resets, the torsion spring releases its potential energy to push the flipping block back to its original position, allowing the push block to quickly disengage from the force-bearing teeth, providing a buffer for the next drive cycle and extending the device's service life.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-4 As shown, a bridge rotation device of this disclosure is illustrated, comprising:

[0032] Drive ring 1, with a clamping ring 2 provided on the outside of drive ring 1;

[0033] Drive rotation component 3, which is located inside clamping ring 2;

[0034] The splicing fastening component 4 is mounted on the clamping ring 2;

[0035] The drive rotation assembly 3 includes a drive cavity 3-1, an installation shaft 3-2 is provided inside the drive cavity 3-1, a flipping block 3-3 is fitted on the installation shaft 3-2, a push rod 3-4 is provided on the flipping block 3-3, a push block 3-5 is provided at the end of the push rod 3-4, and a force-receiving tooth 3-6 is provided on the outer wall of the drive ring 1, and the push block 3-5 is in contact with the force-receiving tooth 3-6.

[0036] The splicing fastening assembly 4 includes a connecting piece 4-1, which is disposed on the side wall of the clamping ring 2. The connecting piece 4-1 is provided with a positioning groove 4-2 and a clamping buckle 4-3. The side wall of the clamping buckle 4-3 is provided with a clamping piece 4-4, which is fixedly clamped to the connecting piece 4-1.

[0037] In some examples, the drive ring 1 is the core component, with the clamping ring 2 tightly fitted on the outside. The drive rotation assembly 3 is placed inside the clamping ring 2. Specifically, the drive cavity 3-1 is first placed in a suitable position, and then the mounting shaft 3-2 is securely placed inside the drive cavity 3-1. After completing the above steps, the push rod 3-4 is installed on the flipping block 3-3. The end of the push rod 3-4 is connected to the push block 3-5, ensuring that the push block 3-5 can make good contact with the force-bearing teeth 3-6 on the outer wall of the drive ring 1. Since the force-bearing teeth 3-6 are ratchet-shaped oblique teeth, there are several push blocks 3-5 evenly distributed on the inner wall of the clamping ring 2. During installation, it is necessary to ensure that the contact position between each push block 3-5 and the force-bearing teeth 3-6 is accurate to achieve efficient power transmission. The splicing fastening assembly 4 is set on the clamping ring 2, the connecting piece 4-1 is installed on the side wall of the clamping ring 2, and the positioning groove 4-2 and the clamping buckle 4-3 are set on the connecting piece 4-1.

[0038] When the pushing block 3-5 pushes the force-bearing tooth 3-6 to rotate the drive ring 1 by a certain angle, the torsion steel spring 3-9 stores elastic potential energy. When the pushing block 3-5 disengages from the current force-bearing tooth 3-6, the torsion steel spring 3-9 releases its elastic potential energy, causing the flipping block 3-3 to reset, so that the pushing block 3-5 can contact the next force-bearing tooth 3-6 and continue to push the drive ring 1 to rotate. During the use of the bridge rotation device, the splicing fastening assembly 4 plays a role in stabilizing the connection. After the clamping ring 2 is fitted with the bridge column, the clamping buckle 4-3 on the connecting piece 4-1 is fixedly clamped to the connecting piece 4-1 through the clamping piece 4-4, which further enhances the stability of the connection between the clamping ring 2 and the bridge column. Especially during the bridge rotation process, it may be subjected to various external forces. The splicing fastening assembly 4 can effectively prevent the clamping ring 2 and the bridge column from loosening or displacement, ensuring the reliability of the entire rotation device. The clamping anti-slip pad 6 inside the clamping buckle 4-3 increases the friction, making the connection more secure.

[0039] like Figures 1-4 As shown, in this embodiment, the flipping block 3-3 has a connecting hole 3-7, the inside of the connecting hole 3-7 is provided with a stepped groove 3-8, and a torsion steel spring 3-9 is provided in the stepped groove 3-8. The top of the torsion steel spring 3-9 is fixedly connected to the drive cavity 3-1.

[0040] In some examples, the flip block 3-3 is fitted onto the mounting shaft 3-2, and the connecting hole 3-7 on the flip block 3-3 mates with the mounting shaft 3-2. A torsion steel spring 3-9 is installed in the stepped groove 3-8 inside the connecting hole 3-7. There are two stepped grooves 3-8, located at the upper and lower ends of the connecting hole 3-7 respectively, and a torsion steel spring 3-9 is installed in both stepped grooves 3-8. The top of the torsion steel spring 3-9 is fixedly connected to the drive cavity 3-1.

[0041] For example, such as Figure 1As shown, the clamping ring 2 is composed of two semi-circular structures spliced ​​together. The clamping ring 2 is provided with a connecting buckle 7, and the clamping ring 2 is connected by a pin through the connecting buckle 7.

[0042] In some examples, the clamping ring 2 is designed as two semi-circular structures, which are spliced ​​together by connecting buckles 7 with pins. When splicing, it is necessary to ensure that the pins of the connecting buckles 7 are installed firmly to prevent loosening during subsequent use.

[0043] For example, such as Figure 1 As shown, the inner sidewall of the clamping ring 2 is provided with a fitting tooth 5, which is fixedly fitted with the bridge column.

[0044] In some examples, the inner wall of the clamping ring 2 is provided with fitting teeth 5, which are used to fix the device to the bridge column. When fitting the device, it is necessary to ensure that the fitting teeth 5 fit tightly with the bridge column. Professional tools can be used for fine adjustment to ensure that the device is firmly connected to the bridge column, providing a solid foundation for subsequent rotation operations.

[0045] For example, such as Figure 1 As shown, the force-bearing teeth 3-6 are ratchet-shaped oblique teeth, and there are several pushing blocks 3-5, which are evenly distributed on the inner sidewall of the clamping ring 2.

[0046] For example, such as Figure 3 As shown, the clamping buckle 4-3 has an I-shaped structure, and the inside of the clamping buckle 4-3 is provided with a clamping anti-slip pad 6.

[0047] In some examples, the clamping buckle 4-3 has an I-shaped structure with an anti-slip pad 6 installed inside. During installation, ensure that the anti-slip pad is in the correct position to enhance the clamping effect. The clamping piece 4-4 on the side wall of the clamping buckle 4-3 is fixedly clamped to the connecting piece 4-1. During installation, the tightness of the clamping should be checked to prevent loosening.

[0048] For example, such as Figure 4 As shown, there are two stepped grooves 3-8, which are located at the upper and lower ends of the connecting hole 3-7 respectively. Torsion steel springs 3-9 are installed inside both stepped grooves 3-8.

[0049] In some examples, when it is necessary to drive the bridge to rotate, the drive rotation component 3 starts to work. An external power source (such as a hydraulic cylinder, not shown in the figure) drives the mounting shaft 3-2 to rotate. The rotation of the mounting shaft 3-2 causes the flipping block 3-3 to rotate around it. During the rotation of the flipping block 3-3, the push rod 3-4 moves with the flipping block 3-3. The push block 3-5 at the end of the push rod 3-4 will contact the force-bearing teeth 3-6 on the outer wall of the drive ring 1 and push the force-bearing teeth 3-6. Since the force-bearing teeth 3-6 are ratchet-shaped oblique teeth, the push block 3-5 will cause the drive ring 1 to rotate during the process of pushing the force-bearing teeth 3-6. Multiple push blocks 3-5 are evenly distributed on the inner wall of the clamping ring 2. They work together to ensure the stability and continuity of the rotation of the drive ring 1. During the process of the push block 3-5 pushing the force-bearing teeth 3-6, the torsion steel spring 3-9 in the connecting hole 3-7 on the flipping block 3-3 plays a role in buffering and resetting.

[0050] In use, the bridge rotation device uses a hydraulic cylinder as the power source for the push rod 3-4. When the device is in its initial state, the drive ring 1, clamping ring 2, drive rotation assembly 3, and splicing fastening assembly 4 are all installed as required. The clamping ring 2 is securely connected to the bridge column through the sleeve teeth 5. At this time, the push rod 3-4 is in its initial position without the hydraulic cylinder applying power. The push block 3-5 and the ratchet-shaped oblique force-bearing teeth 3-6 on the outer wall of the drive ring 1 are in slight contact. The torsion steel spring 3-9 in the connecting hole 3-7 on the flipping block 3-3 is in its natural state and has not deformed.

[0051] When the bridge needs to be rotated, the hydraulic cylinder starts to work. The piston inside the hydraulic cylinder is displaced under the action of hydraulic oil, which in turn pushes the push rod 3-4 connected to the piston. Under the push of the hydraulic cylinder, the push rod 3-4 drives the tilting block 3-3 to rotate around the mounting shaft 3-2. As the tilting block 3-3 rotates, the push block 3-5 at the end of the push rod 3-4 gradually comes into close contact with the force-bearing teeth 3-6 on the outer wall of the drive ring 1 and applies a thrust to it.

[0052] Because the force-bearing teeth 3-6 have a ratchet-like oblique structure, the pusher block 3-5 will push the drive ring 1 to rotate along the oblique direction of the force-bearing teeth 3-6 under the action of thrust. Multiple pusher blocks 3-5 evenly distributed on the inner sidewall of the clamping ring 2 will work together under the synchronous drive of the hydraulic cylinder to ensure that the drive ring 1 can rotate stably and continuously. During the process of the pusher block 3-5 pushing the force-bearing teeth 3-6 to make the drive ring 1 rotate, the rotation of the flipping block 3-3 will compress the torsion steel spring 3-9 in the stepped grooves 3-8 at both ends of the connecting hole 3-7. The torsion steel spring 3-9 stores elastic potential energy and plays a buffering role to avoid rigid impact during the pushing process and protect the device components.

[0053] When the pusher block 3-5 pushes the force-bearing tooth 3-6 to rotate the drive ring 1 by a certain angle, the piston of the hydraulic cylinder reaches its stroke limit and the hydraulic cylinder briefly stops pushing. At this time, the compressed torsion steel spring 3-9 begins to release its elastic potential energy, pushing the flipping block 3-3 to rotate in the opposite direction and reset, so that the pusher block 3-5 disengages from the current force-bearing tooth 3-6 and returns to the vicinity of the initial position. Subsequently, the hydraulic cylinder starts again and repeats the above pushing process. The pusher block 3-5 contacts the next force-bearing tooth 3-6 and continues to push the drive ring 1 to rotate. This cycle repeats, realizing the continuous rotation of the bridge.

[0054] During the bridge rotation process, the splicing fastening assembly 4 and the clamping ring 2 play an important role. The connecting piece 4-1 in the splicing fastening assembly 4 is set on the side wall of the clamping ring 2. The clamping buckle 4-3 is fixedly clamped to the connecting piece 4-1 by the clamping piece 4-4. The clamping anti-slip pad 6 inside the clamping buckle 4-3 increases the friction and ensures that the connection between the clamping ring 2 and the bridge column is stable, preventing loosening or displacement due to force during the rotation. The sleeve teeth 5 on the inner side wall of the clamping ring 2 are tightly engaged with the bridge column, providing a stable support foundation for the entire rotation device and ensuring that the bridge can rotate smoothly when the drive ring 1 rotates.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
