Description

Technical Field

[0001] This utility model belongs to the field of swivel ball joint technology, specifically, it relates to an assembled swivel ball joint. Background Technology

[0002] Bridge rotation construction technology is a method that utilizes the bridge structure itself and its steel components as construction facilities. Through a sliding track with a very low coefficient of friction and a well-designed turntable structure, the prefabricated bridge structure is rotated and installed into place as a whole. This construction method can minimize the impact on nearby transportation routes and overcome the challenges of constructing long-span bridges in high mountain valleys, deep and fast-flowing waterways, or areas with frequent ship traffic.

[0003] Currently, the axis used in the rotation construction of highways and bridges in China is mostly a separate concrete or steel structure. These components need to be dismantled after the rotation is completed, which not only increases the use of engineering materials but also prolongs the construction period and greatly reduces work efficiency.

[0004] In recent years, with the continuous development of bridge rotation construction technology, the rotating spherical hinge structure, as a new type of mechanical connection, has been widely used in various mechanical equipment. The rotating spherical hinge structure combines a spherical hinge structure with a rotational connection method, enabling free rotation in multiple directions, bearing greater loads, and exhibiting better adaptability. However, for ultra-large tonnage rotating spherical hinge bearings, such as those with a diameter exceeding 5 meters, the increased structural dimensions and weight pose significant challenges in processing and transportation. Furthermore, for large-tonnage rotating spherical hinge bearings, the grouting concrete at the lower spherical hinge is difficult to compact, which affects the performance of the spherical hinge and reduces its load-bearing capacity and durability.

[0005] In summary, existing technologies present numerous difficulties in the processing, transportation, hoisting, and installation of ultra-large tonnage rotating ball joint supports, necessitating a new device to overcome these shortcomings. Utility Model Content

[0007] The technical solution used in this utility model is as follows:

[0008] An assembled rotating ball joint includes an upper ball joint assembly, a lower ball joint assembly, a sliding plate, a pre-embedded steel plate, an anchoring assembly, and a leveling mechanism. The upper ball joint assembly has annular and radial stiffening ribs on its top surface and a circular arc surface on its bottom surface. The lower ball joint assembly has a concave arc surface on its top surface. The upper and lower ball joint assemblies are rotatably connected. The sliding plate is distributed between the upper and lower ball joint assemblies. The pre-embedded steel plate is composed of multiple steel plate segments and is fixedly connected to the bottom of the lower ball joint assembly. Multiple grouting holes are provided on the pre-embedded steel plate. The anchoring assembly is fixedly connected to the pre-embedded steel plate. The leveling mechanism is disposed on the pre-embedded steel plate.

[0009] Furthermore, the upper ball joint assembly includes a central upper ball joint and an outer ring upper ball joint. The central upper ball joint and the outer ring upper ball joint are fixedly connected by circumferential fixing bolts. The outer ring upper ball joint is composed of multiple outer ring upper ball joint pieces, which are fixedly connected by radial fixing bolts.

[0010] Furthermore, the outer edge of the central ball joint is provided with a concave groove one, and the inner ring of the outer ring ball joint is provided with a concave groove two, and the concave groove one and the concave groove two cooperate with each other.

[0011] Furthermore, the lower ball joint assembly includes a central lower ball joint and an outer ring lower ball joint.

[0012] Furthermore, the outer periphery of the central lower ball joint is provided with a concave groove one, and the inner ring of the outer ring lower ball joint is provided with a concave groove two. The concave groove one and the concave groove two cooperate with each other, the central lower ball joint is fixedly connected to the outer ring lower ball joint, and the lower ball joint assembly is fixedly connected to the embedded steel plate through the anchoring assembly.

[0013] Furthermore, the lower ball joint assembly also includes a fixing plate and fixing bolts, and multiple fixing plates and fixing bolts are provided. The outer ring lower ball joint is composed of multiple outer ring lower ball joint pieces. The fixing plate is provided at the circumferential splice of every two outer ring lower ball joint pieces. The fixing bolts pass through the fixing plate and are fixedly connected to the outer ring lower ball joint pieces.

[0014] Furthermore, the lower ball joint assembly is fixedly connected to the embedded steel plate by multiple pins, and the joints formed between the steel plate segments are staggered from the joints formed between the lower ball joint segments of the outer ring.

[0015] Furthermore, the top surface of the lower ball joint assembly is provided with a sliding plate mounting groove, and the sliding plate is disposed in the sliding plate mounting groove.

[0016] Furthermore, it also includes a ball joint bracket, which is located at the bottom of the embedded steel plate and is fixedly connected to the leveling mechanism.

[0017] Furthermore, it also includes a central pin, which is fixed in the center of the lower ball joint assembly and the embedded steel plate. The upper ball joint assembly has a hole in the center, which mates with the central pin.

[0019] 1. The upper ball joint assembly of this utility model includes a central upper ball joint and an outer ring upper ball joint, connected by circumferential fixing bolts and radial fixing bolts; the lower ball joint assembly also adopts a split design, consisting of a central lower ball joint and an outer ring lower ball joint.

[0021] 3. This utility model adjusts the flatness of the embedded steel plate by adjusting the screw, which further ensures the flatness and uniformity of the force distribution during the installation of the lower ball joint assembly, and improves the efficiency and accuracy of the installation and adjustment.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] The technical solutions in the embodiments of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0034] This utility model provides an assembled rotating ball joint, including an upper ball joint assembly 1, a lower ball joint assembly 2, a sliding plate 3, a pre-embedded steel plate 4, anchoring components 8, and a leveling mechanism 9. The upper ball joint assembly 1 has annular and radial stiffening ribs on its top surface, and its bottom surface is an arc surface. The top surface of the lower ball joint assembly 2 is a concave arc surface, and the arc surface and the concave arc surface have the same curvature. The upper ball joint assembly 1 and the lower ball joint assembly 2 are rotatably connected. The sliding plate 3 is distributed between the upper ball joint assembly 1 and the lower ball joint assembly 2. The pre-embedded steel plate 4 is composed of multiple steel plate segments 41 and is fixedly connected to the bottom of the lower ball joint assembly 2. Multiple grouting holes 42 are opened on the pre-embedded steel plate 4. Multiple anchoring components 8 are fixedly connected to the pre-embedded steel plate 4. Multiple leveling mechanisms 9 are provided, all of which are set on the pre-embedded steel plate 4.

[0035] After assembling and splicing the pre-embedded steel plate 4, it is fixedly connected to the lower ball joint assembly 2, ensuring that the concave arc surface of the lower ball joint assembly 2 faces upward. A sliding plate 3 is laid on the concave arc surface of the lower ball joint assembly 2 to reduce the frictional resistance between the upper ball joint assembly 1 and the lower ball joint assembly 2 during relative rotation, making the rotation process smoother and reducing energy consumption and wear. The arc surface of the upper ball joint assembly 1 is aligned with the concave arc surface of the lower ball joint assembly 2 and rotated and connected. The anchoring assembly 8 set on the pre-embedded steel plate 4 is used to firmly anchor the rotating ball joint to the foundation. The flatness of the pre-embedded steel plate 4 is adjusted by the leveling mechanism 9, thereby accurately leveling the entire rotating ball joint to ensure stability and safety during the rotation process. Finally, grouting materials such as mortar are injected through the grouting holes 42 on the pre-embedded steel plate 4 and it is observed whether the filling is dense. After the grouting material is completely cured, the stability of the entire rotating ball joint is further improved.

[0036] Example 1

[0037] Specifically, such as Figure 1 and Figure 2 As shown in Embodiment 1, the upper ball joint assembly 1 includes a central upper ball joint 11 and an outer ring upper ball joint 12. The central upper ball joint 11 and the outer ring upper ball joint 12 are fixedly connected by a circumferential fixing bolt 13. The outer ring upper ball joint 12 is composed of multiple outer ring upper ball joint pieces. In this embodiment, four pieces are provided. The four outer ring upper ball joint pieces are fixedly connected by a radial fixing bolt 14.

[0038] like Figure 3 As shown, the lower ball joint assembly 2 includes a central lower ball joint 21, an outer ring lower ball joint 22, a fixing plate 23, and fixing bolts 24.

A fixing plate 23 is provided at the circumferential joint of every two outer ring lower ball joint pieces. The fixing bolts 24 pass through the fixing plate 23 and are fixedly connected to the outer ring lower ball joint pieces. Thus, the outer ring lower ball joint pieces are fixedly connected to each other, forming a single unit. This modular design simplifies the assembly and disassembly process, facilitating rapid on-site construction and subsequent maintenance.

[0039] like Figure 1 As shown, the lower ball joint assembly 2 and the embedded steel plate 4 are fixedly connected by multiple pins 6. A central pin 5 is also fixed in the center of the lower ball joint assembly 2 and the embedded steel plate 4. A hole is opened in the center of the upper ball joint assembly 1. The hole cooperates with the central pin 5 to realize a reliable rotational connection between the upper ball joint assembly 1 and the lower ball joint assembly 2.

[0040] like Figure 4As shown, in this embodiment, the embedded steel plate 4 is composed of four steel plate segments 41. The joints formed between each steel plate segment 41 are staggered from the joints formed between the lower ball joint pieces of the outer ring, which facilitates splicing and fixing, ensures the overall performance of the large-tonnage ball joint device, and reduces the difficulty of transporting, processing and installing the ball joint device.

[0041] like Figure 1 As shown, in order to facilitate the leveling of the embedded steel plate 4 and ensure the flatness and uniformity of the lower ball joint assembly 2 during installation, a ball joint bracket 7 is also provided. The ball joint bracket 7 is located at the bottom of the embedded steel plate 4, and multiple leveling mechanisms 9 are fixedly installed on the ball joint bracket 7. The ball joint bracket 7 can stably support and fix the embedded steel plate 4 and the lower ball joint assembly 2, providing a solid foundation for the leveling mechanism 9. Due to the presence of the ball joint bracket 7, the leveling mechanism 9 has a larger adjustment space and flexibility. The leveling mechanism 9 will not be disturbed by external factors during the adjustment process, thereby improving the accuracy and reliability of leveling.

[0042] Example 2

[0043] Specifically, such as Figure 5 and Figure 6 As shown in Embodiment 2, the upper ball joint assembly 1 includes a central upper ball joint 11 and an outer ring upper ball joint 12. The central upper ball joint 11 has a circular hole at the bottom center. A concave groove 1 is provided on the outer edge of the central upper ball joint 11. A concave groove 2 is provided on the inner ring of the outer ring upper ball joint 12. The concave groove 1 and the concave groove 2 are engaged and secured with a circumferential fixing bolt 13. The outer ring upper ball joint 12 is composed of multiple outer ring upper ball joint pieces, which are fixed together with radial fixing bolts 14.

[0044] Specifically, such as Figure 5 and Figure 7 As shown, the top surface of the lower ball joint assembly 2 is provided with a sliding plate mounting groove 25, and the sliding plate 3 is embedded in the sliding plate mounting groove 25. The lower ball joint assembly 2 includes a central lower ball joint 21 and an outer ring lower ball joint 22. A cylindrical boss is provided in the center of the central lower ball joint 21. The cylindrical boss cooperates with the circular hole of the central upper ball joint 11 to realize the rotational connection between the upper ball joint assembly 1 and the lower ball joint assembly 2. In addition, a concave groove 1 is provided on the outer periphery of the central lower ball joint 21, and a concave groove 2 is provided on the inner ring of the outer ring lower ball joint 22. The concave groove 1 and the concave groove 2 cooperate to fix the central lower ball joint 21 and the outer ring lower ball joint 22. The grooves of the upper and lower ball joint assemblies 2 are interlocked, which facilitates splicing and fixing. This design not only ensures the overall load-bearing capacity of the ball joint support, but also reduces the difficulty of installation and adjustment of the upper and lower ball joint assemblies 2. Through precise splicing and fixing, the stability and safety of the ball joint during rotation can be ensured. An anchoring component 8 is provided around the outer ring lower ball hinge 22. The lower ball hinge component 2 and the pre-embedded steel plate 4 are fixedly connected by the anchoring component 8.
