[0045] In addition, if the embodiments of the present application involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0046] Please refer to Figure 1 As shown in the drawings, the present application provides a large-tonnage block assembly type swivel spherical hinge 10, which includes a lower spherical hinge 11, an upper spherical hinge 12 and a pre-embedded base 13.

[0047] Please refer to Figure 2 , Figure 4 and Figure 5 As shown in the drawings, the upper spherical hinge 12 is divided into two upper spherical hinge sub-modules 121, the lower spherical hinge 11 is divided into two lower spherical hinge sub-modules 111, and the pre-embedded base 13 is divided into two pre-embedded base sub-modules 131. In this embodiment, the upper spherical hinge 12, the lower spherical hinge 11 and the pre-embedded base 13 are generally cylindrical, and the upper spherical hinge 12, the lower spherical hinge 11 and the pre-embedded base 13 are divided from the diameter direction. Thus, after division, the two parts have the same mass and volume, which, under the premise of facilitating transportation, avoids a large number of divided blocks, improves the difficulty of on-site installation and debugging, increases the on-site installation and debugging time, and causes the construction progress to slow down. Further, the lower spherical hinge 11 has a concave spherical surface 112, the upper spherical hinge 12 has a convex spherical surface 122, and the lower spherical hinge 11 and the upper spherical hinge 12 are arranged at the rotation shaft as the rotation center. In this embodiment, the two lower spherical hinge sub-modules 111 are assembled with each other to form the concave spherical surface 112, the two upper spherical hinge sub-modules 121 are assembled with each other to form the convex spherical surface 122, and the pin shaft 14 is arranged on the pre-embedded base 13. The center of the lower spherical hinge 11 is arranged in the pin hole 113 through which the pin shaft 14 passes. Specifically, the two lower spherical hinge sub-modules 111 are each provided with a through half-circular assembly hole 1111, and the half-circular assembly holes 1111 are assembled to form the pin hole 113. Please refer to Figure 6As shown, the upper spherical hinge sub-module 121 is provided with a semicircular groove 1211 on the bottom surface of the upper spherical hinge sub-module 121, and the semicircular groove 1211 is arranged at the center of the upper spherical hinge sub-module 121. After the two upper spherical hinge sub-modules 121 are assembled, the semicircular groove 1211 is not penetrated, so that the two semicircular grooves 1211 can be inserted into the pin shaft 14 to form a rotating shaft for the rotation of the upper spherical hinge 12. In the actual rotation process, the bridge is fixedly connected to one side of the upper spherical hinge 12 away from the convex spherical surface 122. The construction personnel only need to rotate the bridge, and the upper spherical hinge 12 can rotate around the rotating shaft under the action of the bridge torque, thereby realizing the rotation of the upper spherical hinge 12 on the lower spherical hinge 11.

[0048] Please refer to Figure 7 As shown, the embedded base 13 is used for embedding into the foundation pit 20. In actual installation, the foundation pit 20 can be first filled with concrete, and then the embedded base 13 is inserted into the foundation pit 20 to realize that the embedded base 13 and the foundation pit 20 form an integral structure, or the embedded base 13 is first inserted into the base, and then the concrete is poured into the pouring hole 136 of the embedded base 13 to realize that the embedded base 13 and the foundation pit 20 form an integral structure. In this embodiment, the latter is used to realize the connection between the embedded base 13 and the foundation pit 20. The advantage of this arrangement is that the pouring amount of concrete can be accurately controlled through the pouring hole 136, so as to avoid that when the pouring amount is small, the concrete is difficult to be effectively connected with the foundation pit 20, resulting in poor connection tightness, and when the pouring amount is large, since there is too much concrete in the foundation pit 20, it is difficult to ensure the flatness of the surface of the embedded base 13 after the embedded base 13 is inserted into the foundation pit 20, that is, the embedded base 13 is prone to tilt during installation. It is not difficult to understand that the embedded base 13 has the advantages of being able to make the large-tonnage split-assembled rotating spherical hinge 10 firm and immovable, thereby improving the safety and reliability.

[0049] The two lower spherical hinge sub-modules 111 each have a first split surface 1112 formed by splitting. The outer periphery of the lower spherical hinge sub-module 111 is provided with a first connecting portion 1113, and the first split surface 1112 of the lower spherical hinge sub-module 111 is provided with a second connecting portion 1114. The first connecting portion 1113 and the second connecting portion 1114 are used for pre-connecting the lower spherical hinge 11. In actual construction, the first connecting portion 1113 and the second connecting portion 1114 can be used to pre-connect the two lower spherical hinge sub-modules 111 during pouring of the embedded base 13 and the foundation pit 20, thereby shortening the construction time and improving the construction efficiency. At the same time, the first connecting portion 1113 and the second connecting portion 1114 can be connected to the two lower spherical hinge sub-modules 111 from two different directions in different directions, thereby improving the connection strength and the tightness and stability of the two lower spherical hinge sub-modules 111. In addition, the first connecting portion 1113 and the second connecting portion 1114 can also improve the diversity of the connection.

[0050] The embedded base 13 is provided with a clamping groove 132 for inserting the lower spherical hinge 11. In this embodiment, the area of the clamping groove 132 is matched with the area of the lower spherical hinge 11, so as to meet the insertion of the lower spherical hinge 11. It can be understood that the connection of the lower spherical hinge 11 and the embedded base 13 is realized through the clamping groove 132, compared with the connection realized through fasteners such as bolts, the connection process is simplified, the installation time is shortened, at the same time, the clamping groove 132 can provide positioning for the lower spherical hinge 11, in addition, the lower spherical hinge 11 is subjected to the vertical gravity of the upper spherical hinge 12, when the lower spherical hinge sub-module 111 generates a horizontal component force, the groove wall of the clamping groove 132 can provide support force for the lower spherical hinge sub-module 111, so as to avoid the disassembly of the lower spherical hinge 11.

[0051] The two upper spherical hinge sub-modules 121 have a second division surface 1212 formed by division, the second division surface 1212 of one upper spherical hinge sub-module 121 is provided with a positioning step 1213, and the second division surface 1212 of the other upper spherical hinge sub-module 121 is provided with a matching step 1214, the positioning step 1213 and the matching step 1214 are used for pre-positioning the upper spherical hinge 12. In actual installation, only the positioning step 1213 and the matching step 1214 of the two upper spherical hinge sub-modules 121 are aligned and clamped with each other, and then the two upper spherical hinge sub-modules 121 are hoisted to the concave spherical surface 112 of the lower spherical hinge 11, the installation of the large-tonnage block assembly type swivel hinge 10 can be completed, it can be understood that since the matching step 1214 can provide a clamping position for the positioning step 1213, the assembly of the two upper spherical hinge sub-modules 121 is facilitated, at the same time, since the matching step 1214 and the positioning step 1213 are clamped with each other, the misalignment of the two upper spherical hinge sub-modules 121 can be avoided during hoisting, and the need for multiple debugging is avoided, so as to shorten the assembly time and improve the installation efficiency.

[0052] Further, the second split surface 1212 of one upper spherical hinge sub-module 121 is convex to form a positioning step 1213, and the second split surface 1212 of another upper spherical hinge sub-module 121 is concave to form a matching step 1214. In the embodiment, the second split surface 1212 has a first side 12121 and a second side 12122 arranged oppositely, wherein the first side 12121 is connected with the convex spherical surface 122, the positioning step 1213 is arranged on the second split surface 1212 of one upper spherical hinge sub-module 121 close to the second side 12122, and the matching step 1214 is arranged on the second split surface 1212 of another upper spherical hinge sub-module 121 close to the second side 12122. In this way, after the positioning step 1213 and the matching step 1214 are clamped, the two upper spherical hinge sub-modules 121 are close to each other under the action of gravity during hoisting, and the upper spherical hinge sub-module 121 is not prone to dislocation. The positioning step 1213 and the matching step 1214 extend from the second split surface 1212 along the cutting direction, so that the contact area of the positioning step 1213 and the matching step 1214 is increased, and the stability of the connection is improved. The positioning step 1213 has a positioning surface 12131, and the matching step 1214 has a matching surface 12141. The positioning surface 12131 and the matching surface 12141 are both flat surfaces, so that the positioning surface 12131 and the matching surface 12141 can be attached to each other, thereby improving the stability of the connection and facilitating the production and manufacture of the positioning step 1213 and the matching step 1214.

[0053] Please refer to Figure 1 As shown in FIG. 1, the two lower spherical hinge sub-modules 111 are assembled from a first direction, and the two pre-embedded base sub-modules 131 are assembled from a second direction. The first direction and the second direction can intersect. Herein, the first direction and the second direction intersect means that the first direction and the second direction are two different directions, that is, the assembly direction of the two lower spherical hinge sub-modules 111 and the assembly direction of the two pre-embedded base sub-modules 131 are staggered. The advantage of this arrangement is that the horizontal component direction of the force of the two lower spherical hinge sub-modules 111 and the assembly direction of the two pre-embedded base sub-modules 131 are different, so that the force of the pre-embedded base 13 is more stable, thereby improving the stability of the lower spherical hinge 11.

[0054] Preferably, the first direction and the second direction intersect at an angle of 90°, which can further improve the stability of the force of the pre-embedded base 13.

[0055] Please refer to Figure 7 and Figure 8As shown, the bottom surface of the embedded base 13 is provided with a plurality of anchor bars 133. Among them, the anchor bars 133 are used to contact the bottom surface of the foundation pit 20 to realize the standing of the embedded base 13 on the foundation pit 20, and then realize the pouring of the concrete in the foundation pit 20 through the pouring hole 136 on the embedded base 13. Further, the plurality of anchor bars 133 are each provided with a height-adjusting bolt 1331, and the plurality of height-adjusting bolts 1331 are each height-adjustable. Among them, the height-adjusting bolt 1331 is arranged at the bottom of the anchor bar 133, the bottom of the anchor bar 133 is provided with a bolt connecting port for the height-adjusting bolt 1331 to be screwed into, and the bolt connecting port extends from the height direction of the anchor bar 133, the height-adjusting bolt 1331 is used to be tightened to realize the height reduction of the anchor bar 133, and the height-adjusting bolt 1331 is used to be loosened to realize the height increase of the anchor bar 133. The advantage of such arrangement is that on the one hand, the height-adjusting bolt 1331 can be adjusted according to the height of the foundation pit 20, so as to realize the flush of the embedded base 13 with the foundation pit 20, so as to avoid that the height of the anchor bar 133 is too high or too low to meet the depth requirement of the on-site foundation pit 20, and on the other hand, since the bottom surface of the foundation pit 20 is uneven, the height-adjusting bolts 1331 of the plurality of anchor bars 133 can be adjusted with each other to adapt to the uneven bottom surface of the foundation pit 20, so as to realize that the embedded base 13 is erected on the foundation pit 20 in a horizontal posture, and avoid the inclination.

[0056] Please refer to Figure 9As shown, the bottom surface of the embedded base 13 is provided with a plurality of reinforcing ribs 134 in a longitudinal and transverse staggered manner. It is not difficult to understand that the reinforcing ribs 134 can improve the structural strength of the embedded base 13 to meet the requirement of bearing the upper spherical hinge 12 and the lower spherical hinge 11, so as to improve the stability of the structure. Further, the reinforcing ribs 134 and the bottom surface of the embedded base 13 form pouring cavities 135. It is easy to understand that when the concrete enters the foundation pit 20, it can be in contact with the bottom surface of the embedded base 13 and fill the pouring cavities 135, thereby increasing the contact area between the concrete and the embedded base 13 to increase the stability of the connection between the embedded base 13 and the concrete. Further, each pouring cavity 135 is provided with a pouring hole 136, a vibrating hole 137 and a ventilation hole 138 penetrating through the bottom surface of the embedded base 13. Among them, the concrete can enter the foundation pit 20 through the pouring hole 136, the vibrating hole 137 is used for inserting the vibrating rod to realize the vibrating rod vibrating the concrete in the foundation pit 20, and the ventilation hole 138 is used for discharging air in the concrete. It can be understood that since the concrete in the foundation pit 20 is in a loose state after pouring, which contains 5-20% of the volume of the concrete, by vibrating the vibrating rod, the internal voids and residual air in the concrete can be removed to realize the compactness of the concrete, thereby ensuring the connection quality between the embedded base 13 and the foundation pit 20. Further, the diameter of the pouring hole 136 is greater than that of the vibrating hole 137, and the diameter of the vibrating hole 137 is greater than that of the ventilation hole 138. The advantages of such arrangement are that by using a larger pouring hole 136, the pouring speed of the concrete can be improved to fill the foundation pit 20 in a shorter time, and by using a smaller ventilation hole 138, the structural strength of the embedded base 13 can be reduced due to the large hole in the bottom surface of the embedded base 13. Further, the pouring hole 136 in each pouring cavity 135 is arranged in the middle, and the vibrating hole 137 and the ventilation hole 138 are arranged around. The advantages of such arrangement are that by arranging the pouring hole 136 in the middle, the concrete poured into the foundation pit 20 can spread around the foundation pit 20 under the action of gravity, so as to facilitate the vibrating rod to vibrate, and by arranging the vibrating hole 137 around, the vibrating rod can be in full contact with the concrete to facilitate the removal of the gaps and residual air in the concrete, and by arranging the ventilation hole 138 around, the air removal efficiency can be improved, the removal time can be shortened, and the construction time can be shortened.

[0057] Please refer to Figure 10As shown, the first connecting part 1113 comprises a connecting groove 111311 arranged on the outer wall of the lower spherical hinge sub-module 111, the connecting groove 111311 is recessed towards the inside of the lower spherical hinge sub-module 111, and the lower spherical hinge sub-module 111 further comprises a connecting protrusion 11132, both ends of the connecting protrusion 11132 are provided with a connecting protrusion part 111321, and the connecting protrusion part 111321 is used for inserting into the connecting groove 111311 to connect two lower spherical hinge sub-modules 111. Specifically, in actual use, the two connecting protrusion parts 111321 of the connecting protrusion 11132 can be respectively inserted into the connecting grooves 111311 on the two lower spherical hinge sub-modules 111 to realize the connection of the two lower spherical hinge sub-modules 111. It can be easily understood that the advantage of such arrangement is that by inserting the connecting protrusion 11132 into the connecting groove 111311, the horizontal disassembly of the two lower spherical hinge sub-modules 111 can be avoided to a certain extent, and the vertical disassembly of the two lower spherical hinge sub-modules 111 can also be avoided, thereby improving the connection strength of the two lower spherical hinge sub-modules 111, and since the connecting protrusion 11132 can be connected with the outer walls of the two lower spherical hinge sub-modules 111 as a whole, the integrity of the two lower spherical hinge sub-modules 111 can be improved.

[0058] Further, the connecting groove 111311 is arranged on the outer wall of the lower spherical hinge sub-module 111 close to the first division surface 1112. It can be easily understood that the advantage of such arrangement is that the length of the connecting protrusion 11132 is relatively short, and after the connecting protrusion part 111321 is inserted into the connecting groove 111311, the two lower spherical hinge sub-modules 111 are not easy to separate, and since the length of the connecting protrusion 11132 is relatively short, the connecting protrusion 11132 is not easy to be damaged due to the vertical force generated by the up-down misalignment of the two lower spherical hinge sub-modules 111. The lower spherical hinge sub-module 111 is also provided with an embedding groove 111312, the embedding groove 111312 is recessed from the first division surface 1112 and extends towards the connecting groove 111311, and the groove depth of the embedding groove 111312 is consistent with the thickness of the connecting protrusion 11132. Specifically, the embedding groove 111312 is used for inserting the connecting protrusion 11132, since the embedding groove 111312 extends towards and communicates with the connecting groove 111311, the embedding groove 111312 and the connecting groove 111311 can form a stepped groove 11131, after the connecting protrusion 11132 is inserted into the embedding groove 111312, the connecting protrusion 11132 can be integrally fitted in the stepped groove 11131, so that the connecting protrusion 11132 can be hidden on the outer walls of the two lower spherical hinge sub-modules 111 to improve the integrity and further improve the aesthetic appearance, and since the upper and lower sides of the connecting protrusion 11132 can contact the inner wall of the stepped groove 11131, the vertical positioning of the two lower spherical hinge sub-modules 111 is further realized.

[0059] Further, the connecting groove 111311 is provided with a bolt connecting port, and the connecting convex part 111321 is provided with a bolt through hole for the bolt insertion. The bolt can be inserted into the bolt through hole and threadedly connected with the bolt connecting port. It can be understood that the connecting convex part 11132 can be fixed in the stepped groove 11131 through the bolt and the bolt connecting port threadedly connected, so as to avoid the connecting convex part 11132 from falling off from the stepped groove 11131, thereby causing the two lower spherical hinge sub-modules 111 to be scattered.

[0060] The second connecting part 1114 includes an insertion convex part 11141 and an insertion groove 11142. One of the insertion convex part 11141 and the insertion groove 11142 is arranged on the first division surface 1112 of one lower spherical hinge sub-module 111, and the other is arranged on the first division surface 1112 of another lower spherical hinge sub-module 111. In actual operation, the insertion convex part 11141 of one lower spherical hinge sub-module 111 is only inserted into the insertion groove 11142 of another lower spherical hinge sub-module 111, so as to realize the assembly of the two lower spherical hinge sub-modules 111. The advantage of such arrangement is that the assembly process of the two lower spherical hinge sub-modules 111 is simplified, and after the assembly of the two lower spherical hinge sub-modules 111, the insertion convex part 11141 and the insertion groove 11142 can be hidden, so as to improve the integrity and the aesthetic appearance.

[0061] Please refer to Figure 11 , Figure 12 and Figure 13As shown, the bottom surface of the clamping groove 132 is provided with an anti-rotation groove 1321 recessed towards the inside of the embedded base 13. In this embodiment, two anti-rotation grooves 1321 are provided opposite to the two sides of the clamping groove 132. Further, the bottom surface of the lower spherical hinge sub-module 111 is provided with a matching groove 1115 recessed towards the inside of the lower spherical hinge sub-module 111. In this embodiment, two matching grooves 1115 are provided on the bottom surface of the two lower spherical hinge sub-modules 111. The lower spherical hinge sub-module 111 further comprises an anti-rotation protrusion 1116, the thickness of the anti-rotation protrusion 1116 is greater than the groove depth of the anti-rotation groove 1321. It can be understood that in this way, the anti-rotation protrusion 1116 can be exposed from the anti-rotation groove 1321. Further, the thickness of the anti-rotation protrusion 1116 is less than the sum of the groove depths of the anti-rotation groove 1321 and the matching groove 1115. It can be easily understood that in this way, the anti-rotation protrusion 1116 can avoid lifting the lower spherical hinge sub-module 111, affecting the stability of the lower spherical hinge 11. During the use process, the anti-rotation protrusion 1116 is only placed in the anti-rotation groove 1321, and the matching groove 1115 of the lower spherical hinge sub-module 111 is aligned with the anti-rotation protrusion 1116 to complete the installation. When the upper spherical hinge 12 is rotated by the torque of the bridge, the upper spherical hinge 12 will drive the lower spherical hinge sub-module 111 to rotate, and the anti-rotation protrusion 1116 can provide a limit for the lower spherical hinge sub-module 111 to avoid rotation of the lower spherical hinge sub-module 111.

[0062] Further, the anti-rotation groove 1321 extends from the bottom surface of the clamping groove 132 to the outer periphery of the embedded base 13, and the matching groove 1115 extends from the bottom surface of the lower spherical hinge sub-module 111 to the circumferential side of the lower spherical hinge sub-module 111. Specifically, the extension directions of the anti-rotation groove 1321 and the matching groove 1115 are both the radial direction of the clamping groove 132. It can be easily understood that the direction of the torque received by the lower spherical hinge sub-module 111 from the upper spherical hinge 12 is the circumferential direction. After the anti-rotation protrusion 1116 is placed in the anti-rotation groove 1321, the length direction of the anti-rotation protrusion 1116 is the radial direction of the clamping groove 132, and the radial direction of the clamping groove 132 is perpendicular to the circumferential direction. In this way, the anti-rotation protrusion 1116 can effectively resist the torque received by the lower spherical hinge sub-module 111. Further, the anti-rotation groove 1321 forms a first opening 1322 from the outer periphery of the embedded base 13, and the matching groove 1115 forms a second opening 11151 from the circumferential side of the lower spherical hinge sub-module 111. The advantage of this arrangement is that the anti-rotation protrusion 1116 can be inserted into the anti-rotation groove 1321 and the matching groove 1115 from the first opening 1322 and the second opening 11151, so as to quickly realize the installation of the anti-rotation protrusion 1116, thereby shortening the on-site installation and debugging time.

[0063] Further, the anti-rotation protrusions 1116 are provided with anti-rotation rods 11161, and the anti-rotation rods 11161 are provided in plurality and arranged along the length direction of the anti-rotation protrusions 1116. The groove bottom of the matching groove 1115 is provided with anti-rotation holes 11152 for the anti-rotation rods 11161 to insert, and the anti-rotation holes 11152 are provided in plurality and arranged along the length direction of the matching groove 1115. It is not difficult to understand that by inserting the anti-rotation rods 11161 into the anti-rotation holes 11152, the rotation of the lower ball hinge sub-modules 111 can be further avoided.

[0064] In an embodiment, the concave spherical surface 112 of the lower ball hinge 11 is provided with annular protrusions 1117. Specifically, in this embodiment, the concave spherical surface 112 of the lower ball hinge 11 is provided with four annular protrusions 1117 to divide the concave spherical surface 112 into four annular laying areas for laying wear-resistant plates. It is easy to understand that the wear-resistant plates can prevent the upper ball hinge 12 and the lower ball hinge 11 from being damaged due to wear. Further, the annular protrusions 1117 are provided with sector-shaped wear-resistant plates 15, and the sector-shaped wear-resistant plates 15 are spliced with each other to cover the concave spherical surface 112. It is easy to understand that the wear-resistant plates are designed as sector-shaped, which can ensure complete coverage of the annular laying areas, and on the other hand, due to the large volume of the lower ball hinge 11, laying smaller sector-shaped wear-resistant plates 15 can reduce the production cost, facilitate transportation and on-site installation. In addition, since the lower ball hinge 11 is assembled by the lower ball hinge sub-modules 111, the sector-shaped wear-resistant plates 15 can be installed and fixed on the lower ball hinge sub-modules 111 in advance before on-site installation and debugging, so as to improve the on-site installation efficiency.

[0065] In an embodiment, the upper spherical hinge sub-module 121 is concavely provided with a concrete placement cavity 1215 for placing concrete. It is not difficult to understand that, compared with the traditional method of placing concrete on the side of the upper spherical hinge 12 away from the convex spherical surface 122 and connecting with the bridge, by placing the concrete in the concrete placement cavity 1215 and then connecting with the bridge, the contact area of the concrete and the upper spherical hinge 12 can be increased, thereby improving the stability of the connection between the upper spherical hinge 12 and the bridge. At the same time, since the upper spherical hinge sub-module 121 is provided with the concrete placement cavity 1215, the mass of the upper spherical hinge sub-module 121 is lighter, which is conducive to the transportation and manufacturing of the upper spherical hinge sub-module 121, and further reduces the difficulty of on-site installation and debugging of the upper spherical hinge sub-module 121. Further, the concrete placement cavity 1215 is provided with radial reinforcing ribs 1216 and annular reinforcing ribs 1217 to divide the concrete placement cavity 1215 into multiple. In this embodiment, the radial reinforcing ribs 1216 are convexly provided along the vertical direction from the bottom surface of the concrete placement cavity 1215 and extend from the center of the upper spherical hinge sub-module 121 to the inner wall of the concrete placement cavity 1215, and the annular reinforcing ribs 1217 are convexly provided along the vertical direction from the bottom surface of the concrete placement cavity 1215 and are concentrically arranged with the center of the upper spherical hinge sub-module 121. The radial reinforcing ribs 1216 and the annular reinforcing ribs 1217 intersect to divide the concrete placement cavity 1215 into multiple. The advantage of such arrangement is that the radial reinforcing ribs 1216 and the annular reinforcing ribs 1217 can improve the structural strength of the upper spherical hinge sub-module 121, and after the concrete is mixed with the radial reinforcing ribs 1216 and the annular reinforcing ribs 1217, the shear capacity of the concrete can be improved to avoid the separation of the bridge and the upper spherical hinge 12 during the rotation of the bridge. In addition, dividing the concrete placement cavity 1215 into multiple can increase the contact area of the concrete and the concrete placement cavity 1215, thereby improving the connection tightness of the concrete and the upper spherical hinge sub-module 121. Further, the radial reinforcing ribs 1216, the annular reinforcing ribs 1217 and the upper spherical hinge sub-module 121 are integrally formed, and the radial reinforcing ribs 1216, the annular reinforcing ribs 1217 and the upper spherical hinge sub-module 121 can be integrally formed by any one of injection molding, blow molding, drawing, stamping and 3D printing. The advantage of integrally forming is that it is convenient for the production and manufacturing of the upper spherical hinge sub-module 121, the production cost is low, and the structural strength of the upper spherical hinge sub-module 121 can be improved.

[0066] Further, the second division surface 1212 of the two upper spherical hinge sub-modules 121 is correspondingly provided with a through connecting hole 12123. The positions and sizes of the connecting holes 12123 on the two second division surfaces 1212 correspond. Further, the connecting hole 12123 is installed with a hinge hole bolt 1218. Please refer to Figure 14The hinge hole bolt 1218 has a smooth rod section 12181 and a threaded section 12182. The smooth rod section 12181 has a shaft diameter matched with the hole diameter of the connecting hole 12123, and is used to be inserted into the connecting hole 12123 to position the two upper spherical hinge sub-modules 121 and avoid loosening of the two upper spherical hinge sub-modules 121 in the vertical direction. The threaded section 12182 is used to be screwed with a nut after the smooth rod section 12181 is inserted into the connecting hole 12123, to fasten the two upper spherical hinge sub-modules 121 and avoid loosening of the two upper spherical hinge sub-modules 121 in the horizontal direction. Further, the connecting hole 12123 is provided with a plurality of connecting holes 12123, each of which extends from the second division surface 1212 along the cutting direction, and each of which is provided with a hinge hole bolt 1218. This arrangement has the advantage that the connection strength of the two upper spherical hinge sub-modules 121 can be improved by the cooperation of the plurality of connecting holes 12123 and the plurality of hinge hole bolts 1218, so as to improve the stability of the connection of the two upper spherical hinge sub-modules 121.
