Description

TECHNICAL FIELD

[0001] The present application relates to the field of bridge facilities equipment, in particular to an intelligent swivel spherical hinge. BACKGROUND

[0002] The existing swivel spherical hinge is widely used in the construction process of large structures such as bridges, especially in situations where structure rotation is required. It is usually composed of two spherical hinges, with smooth spherical structures, allowing the two parts to rotate relative to each other, thereby supporting the bridge or other building structures to smoothly perform swivel operations during the construction process. The design principle of such a swivel spherical hinge not only ensures smooth and stable rotation of the bridge structure, but also plays a supporting and load-bearing role, which is an indispensable key component in large building structures. However, the existing swivel spherical hinge lacks intelligent functions, especially in terms of posture monitoring and load measurement. The existing spherical hinge cannot monitor or adjust its load-bearing state in real time, and cannot provide feedback on changes in posture and stress, which makes its performance and safety difficult to guarantee in complex or dynamic working environments.

[0003] In addition, the existing technology also has obvious shortcomings when using the swivel spherical hinge in low temperature environments. Low temperature environments can cause the grease used in them to solidify, significantly reducing its lubricating performance, thereby increasing friction and wear, affecting the rotational flexibility of the spherical hinge. This solidification phenomenon is particularly serious in cold regions or extreme weather conditions, especially during bridge construction or structure rotation. Insufficient lubrication can cause the swivel spherical hinge to work unevenly, even causing damage to mechanical parts, seriously affecting construction progress and safety. In addition, the solidification of the grease in low temperature environments can also cause pressure concentration during structure rotation, thereby accelerating the damage of the equipment and reducing the service life of the swivel spherical hinge.

[0004] Therefore, it is particularly urgent to solve the problem of grease solidification in low temperature environments. In traditional methods, although the use of low-temperature-adapted grease can alleviate this problem, it still cannot fundamentally eliminate the phenomenon of reduced lubricating performance at extremely low temperatures. The properties of the grease limit its flowability at low temperatures, resulting in that even with specially designed grease, it cannot fully meet the needs of low-temperature working environments. Therefore, improving the lubricating performance and intelligent level of the swivel spherical hinge in low temperature environments has become a technical problem that needs to be solved urgently. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to at least overcome one of the deficiencies of the prior art, and to provide an intelligent swivel spherical hinge. The swivel spherical hinge introduces a heating device and multiple sensors. The heating device can effectively heat the working part of the swivel spherical hinge, prevent the grease from solidifying in low temperature environments, maintain its flowability and lubricating performance, and improve the intelligent level of the spherical hinge through multiple sensors sensing spherical hinge data, to meet the needs of intelligent control of bridges.

[0006] To achieve the above object, the application discloses an intelligent rotating body ball hinge, which comprises an upper ball hinge, a lower ball hinge opposite to the upper ball hinge, and at least one heating assembly arranged in the lower ball hinge, wherein the upper ball hinge and the lower ball hinge are matched through a curved surface structure, and a sliding plate is mounted on the matching surface of the upper ball hinge and the lower ball hinge; the heating assembly at least heats the matching surface of the lower ball hinge and the lower ball.

[0007] As an optional technical solution, the center between the upper ball hinge and the lower ball hinge is matched through a rotating shaft structure, which is a shaft column protruding on the lower ball hinge and a central shaft sleeve recessed in the upper ball hinge.

[0008] As an optional technical solution, a posture sensor is mounted on the upper ball hinge and / or the lower ball hinge to sense the matching posture of the upper ball hinge and the lower ball hinge.

[0009] As an optional technical solution, the upper ball hinge and the lower ball hinge are provided with connecting bolts for connecting external structures.

[0010] As an optional technical solution, the upper ball hinge and the lower ball hinge are provided with anchor rods for connecting external structures.

[0011] As an optional technical solution, a weight sensor is mounted in the lower ball hinge.

[0012] As an optional technical solution, the heating assembly has a plurality of heating assemblies close to the matching surface of the upper ball hinge and the lower ball hinge. Preferably, the heating assembly is annular.

[0013] As an optional technical solution, the lower ball hinge has a support structure at the bottom.

[0014] As an optional technical solution, the upper ball hinge is in an inverted character-like convex shape, and the upper ball hinge is in a character-like concave shape.

[0015] Compared with the prior art, the application has at least one of the following beneficial effects:

[0016] 1. Improve the lubrication performance in low temperature environment: by introducing the heating device, the intelligent rotating body ball hinge can effectively prevent the solidification of the lubricating grease in the low temperature environment, maintain the fluidity of the lubricating grease, thereby reducing the friction and wear, and ensuring the smooth operation of the rotating body ball hinge. This technology effectively solves the problem of solidification of lubricating grease in low temperature environment in traditional technology, and improves the stability and reliability of the ball hinge in cold climate conditions.

[0017] 2. Real-time monitoring and feedback of working status: By integrating attitude sensors and weight sensors, the intelligent swivel ball hinge can monitor the attitude changes and load-bearing conditions of the ball hinge in real time. This enables the device to dynamically adjust during the structural rotation according to real-time data, ensuring rotation accuracy and stability, and avoiding performance loss and equipment damage caused by attitude deviation or uneven load.

[0018] 3. Enhanced adaptive capability: Combined with heating devices and sensor technology, the intelligent swivel ball hinge can automatically adjust the working status to adapt to changes in different temperature and load environments. This adaptive capability enables the swivel ball hinge to maintain high efficiency in complex working environments, prolongs the service life of the device, and improves the safety and reliability of the construction process.

[0019] 4. Simplified maintenance and extended service life: As the heating components can effectively prevent the solidification of lubricating grease at low temperatures, and the sensor monitoring function can timely detect potential faults or abnormalities, the intelligent swivel ball hinge reduces the dependence on regular maintenance and reduces the equipment failure rate. This design not only prolongs the service life of the swivel ball hinge, but also reduces maintenance costs and downtime. The above listed benefits are not exhaustive of all advantages. Other potential benefits and detailed technical implementations will be further disclosed in the embodiments or other description sections of this application. BRIEF DESCRIPTION OF DRAWINGS

[0027] Reference is made to the accompanying drawings Figure 1 The following is a description of the embodiments with reference to the appended drawings:

[0028] The present embodiment provides an intelligent swivel ball hinge, mainly used for the rotation operation of large structures such as bridges, and is particularly suitable for occasions that require high-efficiency rotation performance in low-temperature environments. The swivel ball hinge introduces a heating device on the basis of the traditional swivel ball hinge, aiming to solve the problem of solidification of lubricating grease and the decline of lubrication performance in low-temperature environments, so as to ensure that the swivel ball hinge can work smoothly in cold environments. Specifically, the technical scheme provided by the present embodiment achieves the above-mentioned target in the following way.

[0029] Firstly, the swivel ball hinge is composed of an upper ball hinge 1 and a lower ball hinge 2, which are matched through cambered surface structure. The mating surface of the upper ball hinge 1 and the lower ball hinge 2 is installed with a sliding plate 3, which functions to reduce friction and wear, thereby improving the running efficiency of the ball hinge and ensuring smooth rotation. Through the precisely designed matching structure, mechanical failure caused by excessive friction during the rotation of the swivel ball hinge can be effectively avoided. In addition, the sliding plate 3 is made of materials with strong wear resistance and low friction coefficient, such as engineering plastics or alloy materials, which further improves the service life and running efficiency.

[0030] To address the lubrication problem in low temperature environment, at least one heating assembly 8 is configured in the swivel spherical hinge. The heating assembly 8 is located in the lower spherical hinge 2 and is mainly used to heat the contact surface between the lower spherical hinge 2 and the lower spherical hinge, thereby preventing the grease from solidifying in low temperature environment. Specifically, the heating assembly 8 adopts a ring design and is uniformly distributed around the contact surface between the lower spherical hinge 2 and the lower spherical hinge, ensuring uniform heating. The heating assembly 8 adopts an electric heating method, and the heating power can be adjusted according to the actual needs of the site environment, ensuring that the grease maintains good fluidity and lubricity in low temperature.

[0031] Further, the number of heating assemblies 8 can be increased or decreased according to actual work requirements, and the configuration of multiple heating assemblies 8 can better ensure the appropriate temperature of the lubricated surface in low temperature. In addition, the heating assembly 8 used in the present embodiment can select different materials and power to meet the needs in different use environments. For example, in extremely low temperature environment, a higher power heating device can be used to ensure the heating effect.

[0032] In terms of structural design, the upper spherical hinge 1 and the lower spherical hinge 2 are connected through a rotating shaft structure, which includes a shaft column 4 protruding on the lower spherical hinge 2 and a central shaft sleeve 5 recessed in the upper spherical hinge 1. The rotating shaft structure can ensure the precise fit between the upper spherical hinge 1 and the lower spherical hinge 2, and make them flexible to rotate. Through this structure, the instability problem caused by axial deviation during rotation can be effectively avoided, thereby ensuring the smooth operation of the swivel spherical hinge.

[0033] To further improve the performance of the swivel spherical hinge, the present embodiment also configures a posture sensor 6. The sensor 6 can be installed on the upper spherical hinge 1 or the lower spherical hinge 2 and is used to sense the relative fitting posture between the two. The posture sensor 6 can monitor the rotation state of the spherical hinge in real time and feed back the data to the control system. When the sensor 6 detects an abnormality, it can timely send out an alarm signal to prevent mechanical damage or functional failure caused by abnormal fitting posture. The posture sensor 6 usually adopts a high-precision sensor module to ensure the accuracy and reliability of the data.

[0034] In addition, in order to facilitate the installation and connection of external structures, the upper spherical hinge 1 and the lower spherical hinge 2 are both provided with connecting bolts or anchor rods 9 for connecting external structures. The connecting bolts and anchor rods 9 enable the swivel spherical hinge to be firmly connected with the bridge or other building structures and can withstand the gravity and rotating force from the external structure. The design of the connecting part adopts high-strength materials such as alloy steel or stainless steel, which can effectively improve the stability and safety of the connection and ensure the reliability in long-term use.

[0035] A weight sensor 7 is also installed in the lower ball hinge 2, which is used to monitor the load condition of the rotating ball hinge in real time during rotation. The weight sensor 7 transmits monitoring data to the control system through the data acquisition module, and adjusts the working state of the rotating ball hinge according to the real-time load condition. This design can effectively avoid damage to the rotating ball hinge caused by overload or unbalanced load condition, thereby prolonging the service life of the equipment.

[0036] In one embodiment, referring to the accompanying Figure 2 The bottom of the lower ball hinge 2 is provided with a support structure 10 to enhance its support force and stability. The support structure 10 is fixed with the lower ball hinge 2 to ensure that the rotating ball hinge will not be displaced or damaged when subjected to external force, increasing its reliability in long-term use. The support structure 10 uses high-strength materials and stable fixing methods to ensure its long-term durability.

[0037] In the shape design of the upper ball hinge 1 and the lower ball hinge 2 in this embodiment. The upper ball hinge 1 is inverted and similar to the convex shape, while the lower ball hinge 2 is similar to the concave shape. This structural design can effectively improve the matching precision between the two, and ensure a more stable contact surface contact during rotation, making the overall movement process more smooth and stable.

[0038] Through the above design, the rotating ball hinge with heating of the present embodiment can effectively solve the lubrication problem in low temperature environment, and ensure that the rotating ball hinge can work smoothly in cold conditions. Compared with traditional rotating ball hinge, the present embodiment can significantly improve the working efficiency, stability and safety of the equipment, and is especially suitable for large bridge construction, offshore platform construction and other application scenarios in extremely cold or high altitude areas. Through the introduction of the heating device, the lubrication performance can be maintained in low temperature environment, thereby prolonging the service life of the equipment, reducing the maintenance frequency, and ensuring the long-term stable operation of the rotating ball hinge.

Therefore, all changes and modifications are included in the protection scope of the present disclosure defined by the claims.
