Description

Technical Field

[0001] This utility model relates to the field of bridge bearing technology, specifically a low-friction torque rotating bearing. Background Technology

[0002] Swing bearings are crucial components in bridge construction, playing a vital role in bridge rotation during construction and subsequent use. During bridge rotation, the traction equipment must overcome the frictional torque of the swing bearing itself to achieve smooth rotation; therefore, reducing the frictional torque of the swing bearing is key to ensuring successful bridge rotation.

[0003] Applying lubricant to the friction pairs of a slewing support is an effective way to reduce rotational friction. However, over time, the lubricant gradually decreases due to evaporation, aging, and wear during mechanical movement. This directly leads to a gradual increase in frictional resistance during rotation of the slewing support friction pairs, increasing the rotational traction force and exacerbating the risks associated with rotation.

[0004] Furthermore, during the installation of the slewing bearing, if the bearing becomes detached or deformed, the frictional torque of the bearing will increase significantly, seriously affecting the safety of the bridge rotation. Current technology does not offer specific optimizations for this situation, requiring extra attention to installation details to minimize the risk of detachment or deformation. This leads to slow construction progress, and since detachment is often unavoidable, it severely impacts construction quality.

[0005] Therefore, those skilled in the art urgently need a rotating support with low friction, high installation efficiency, and low detachment deformation. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a low frictional torque rotating support to solve the problems of high frictional resistance, low installation efficiency and easy delamination and deformation during the installation process of the existing rotating support.

[0007] This utility model provides a low-friction torque rotating support, which includes: an upper spherical panel, a wear-resistant sliding plate, a lower spherical panel, and an embedded plate. The embedded plate is pre-installed by concrete pouring, and the lower spherical panel is fixedly disposed on the upper surface of the embedded plate. The wear-resistant sliding plate is disposed within the concave spherical surface at the top of the lower spherical panel, and the upper spherical panel is disposed on the upper part of the wear-resistant sliding plate corresponding to the lower spherical panel, and can slide relative to the lower spherical panel. At least one lubricating medium replenishment channel is provided on the side of the lower spherical panel, and the lubricating medium replenishment channel is connected to the surface of the wear-resistant sliding plate for providing lubricating medium.

[0008] Furthermore, the lower ball panel has an upwardly extending pin at its axis, and the upper ball panel has a pin hole corresponding to the pin at its axis, the pin hole engaging with the pin for displacement limiting.

[0009] In this embodiment of the invention, the upper surface of the wear-resistant sliding plate has a grease storage channel, which includes multiple guide channels and multiple evenly arranged storage tanks. The lubricating medium replenishment channel is connected to the guide channels, and the multiple storage tanks are interconnected through the guide channels to transport the lubricating medium.

[0010] Furthermore, a pipe plug is provided at the inlet end of the lubricating medium replenishment channel.

[0011] In this embodiment of the invention, the bottom surface of the embedded plate is fixedly provided with a rib structure for strengthening the structural strength of the embedded plate and serving as a casting template.

[0012] Furthermore, the rib structure includes an annular rib and longitudinal and transverse ribs, wherein the annular rib is disposed around the bottom circumference of the embedded plate, and the longitudinal and transverse ribs are disposed on the bottom surface of the embedded plate within the range of the annular rib.

[0013] Furthermore, the surface of the embedded plate has multiple grouting holes for injecting concrete.

[0014] In this embodiment of the invention, the top of the upper ball panel has a rib structure to enhance structural strength.

[0015] In the embodiments of this utility model, the curvature of the lower surface of the upper ball panel, the curvature of the wear-resistant sliding plate, and the curvature of the upper surface of the lower ball panel are all adapted to each other.

[0016] In this embodiment of the invention, the upper surface of the lower ball panel has a mounting groove, and part of the wear-resistant sliding plate is located in the mounting groove, while part of it extends beyond the mounting groove.

[0017] As can be seen from the above embodiments, the low friction torque rotating bearing provided by this utility model has at least the following benefits: the rotating bearing can replenish the lubricating medium during use, so that the sliding surface of the bearing is always in a long-term lubricated state, reducing the friction coefficient between friction pairs, reducing wear, improving service life, maintaining accurate rotation performance, and providing a solid guarantee for the high-quality construction and operation of bridge engineering.

[0018] In addition, the annular ribs at the bottom of the embedded plate are set at the same height as the pad stone and can also act as concrete formwork, eliminating the need for the support process of erecting pad stone formwork and improving construction efficiency. Furthermore, pouring concrete through the grouting holes on the embedded plate can increase the density of the concrete under the embedded plate and prevent the support from becoming void or deformed.

[0030] Various exemplary embodiments of the present invention are now described in detail. This detailed description should not be considered as a limitation of the present invention, but should be understood as a more detailed description of certain aspects, features and implementations of the present invention.

[0031] Various improvements and variations can be made to the specific embodiments described in this utility model without departing from the scope or spirit of this utility model, which will be obvious to those skilled in the art. Other embodiments derived from this utility model description will also be obvious to those skilled in the art. This application specification and embodiments are merely exemplary.

[0032] This utility model provides a low-friction torque rotating support, such as... Figures 1-3The diagram shows the structure of the rotating support. In a specific embodiment, the rotating support includes: an upper ball face plate 1, a wear-resistant sliding plate 2, a lower ball face plate 3, and an embedded plate 4. The embedded plate 4 is pre-installed by concrete pouring, and the lower ball face plate 3 is fixedly mounted on the upper surface of the embedded plate 4. In this embodiment, the embedded plate 4 and the lower ball face plate 3 can be fixed by bolts, welding, or a flat key connection.

[0033] The wear-resistant sliding plate 2 is disposed within the concave spherical surface at the top of the lower ball panel 3. The upper ball panel 1 is disposed above the wear-resistant sliding plate 2, corresponding to the lower ball panel 3, and is fitted to fit against the wear-resistant sliding plate 2, allowing it to slide relative to the lower ball panel 3. The wear-resistant sliding plate 2 reduces the sliding friction resistance of the upper ball panel 1, improving the rotational flexibility of the support.

[0034] At least one lubricating medium replenishment channel 32 is provided on the side of the lower ball panel 3, which connects to the surface of the wear-resistant slide plate 2 to provide lubricating medium. In this embodiment, the lubricating medium can be continuously replenished to the wear-resistant slide plate 2 through the lubricating medium injection device, reducing the frictional resistance between the upper ball panel 1 and the wear-resistant slide plate 2, further improving the flexibility of the support rotation, and reducing the wear of the wear-resistant slide plate 2, thereby extending its service life.

[0035] Furthermore, the lower ball panel 3 has an upwardly extending pin 31 at its axis, and the upper ball panel 1 has a pin hole 11 corresponding to the pin 31 at its axis. The pin hole 11 and the pin 31 are sleeved together for displacement limiting. There is a certain redundant clearance between the pin hole 11 and the pin 31 to facilitate installation and prevent rotation or displacement jamming.

[0036] In specific embodiments of this utility model, such as Figure 3 As shown, the upper surface of the wear-resistant sliding plate 2 has a grease reservoir, which includes multiple guide channels 21 and multiple evenly arranged storage tanks 22. The lubricating medium replenishment channel 32 is connected to the guide channels 21, and the multiple storage tanks 22 are interconnected through the guide channels 21 to transport the lubricating medium. Preferably, the lubricating medium is silicone grease. During the later stages of use of the support, as the upper ball panel 1 rotates, the silicone grease in the grease reservoir is continuously replenished to the surface of the wear-resistant sliding plate 2 under the action of friction. This continuous replenishment mechanism ensures that the surface of the wear-resistant sliding plate 2 is always covered with a uniform silicone grease lubricating film, effectively reducing the coefficient of friction between the upper ball panel 1 and the wear-resistant sliding plate 2, reducing wear, and thus achieving a long-lasting lubrication effect, greatly extending the service life of the support.

[0037] Furthermore, a pipe plug 33 is provided at the inlet end of the lubricating medium replenishment channel 32 to prevent the lubricating medium from flowing out.

[0038] In specific embodiments of this utility model, such as Figure 2As shown, the bottom surface of the embedded plate 4 is fixedly provided with a rib structure 41 for strengthening the structural strength of the embedded plate 4 and serving as a casting template.

[0039] Furthermore, the rib structure 41 includes annular ribs and longitudinal and transverse ribs. The annular ribs are disposed around the bottom circumference of the embedded plate 4, and the longitudinal and transverse ribs are disposed on the bottom surface of the embedded plate 4 within the range of the annular ribs.

[0040] Normally, a pad stone is required when pouring embedded plates. In this application, the annular rib plate is set at the same height as the pad stone and can also serve as a concrete formwork, eliminating the need for the support process of erecting pad stone formwork and improving construction efficiency.

[0041] The longitudinal and transverse ribs are set within the range of the annular ribs, which plays a role in strengthening the structural strength of the embedded plate 4 and reducing the deformation during the processing and installation of the embedded plate.

[0042] Furthermore, the surface of the embedded plate 4 has multiple grouting holes 42 for pouring concrete. Grouting is carried out one by one through the grouting holes 42 to ensure the compactness of the concrete under the embedded plate 4 and to prevent the support from becoming void and deformed.

[0043] In a specific embodiment of this utility model, the top of the upper ball panel 1 has a rib structure to strengthen the structural strength, prevent deformation, and improve the durability and lifespan of the upper ball panel 1.

[0044] In a specific embodiment of this utility model, the curvature of the lower surface of the upper ball panel 1, the curvature of the wear-resistant sliding plate 2, and the curvature of the upper surface of the lower ball panel 3 are all matched, making the cornering and sliding process smoother.

[0045] In a specific embodiment of this utility model, the upper surface of the lower ball panel 3 has a mounting groove, and part of the wear-resistant sliding plate 2 is located in the mounting groove, while part of it protrudes above the mounting groove. The top surface of the wear-resistant sliding plate 2 protruding above the mounting groove contacts and slides against the bottom surface of the upper ball panel 1. This avoids direct contact between the upper ball panel 1 and the lower ball panel 3.

[0046] The above description is merely an illustrative embodiment of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model shall fall within the scope of protection of this utility model.
