The upper end of the spherical skateboard 143 is in contact with the spherical crown plate 141, and the lower end of the spherical skateboard 143 is in contact with the upper end of the support lower plate 12. That is to say, the upper end of the support lower plate 12 is provided with a spherical surface that cooperates with the spherical skateboard 143. The spherical skateboard 143 can slide relative to the support lower plate 12. By utilizing the sliding between the plane skateboard 142 and the support upper plate 11, it can adapt to the horizontal movement of the bridge. By utilizing the sliding between the spherical skateboard 143 and the spherical crown plate 141, it can adapt to the rotation of the bridge while allowing the support upper plate 11 to slide or rotate relative to the support lower plate 12.

[0048] like Figure 1 to Figure 2As shown, the adjustment mechanism 13 is arranged at the lower end of the support upper plate 11, and the adjustment mechanism 13 protrudes downward to the side of the support lower plate 12, and then the adjustment mechanism 13 limits the displacement of the support lower plate 12 on this side, thereby adjusting the displacement of the support lower plate 12 on the horizontal plane; the adjustment mechanism 13 is arranged on at least one side of the support upper plate 11, that is, the adjustment mechanism 13 can be arranged in the following ways:

[0049] In an optional embodiment, in the horizontal direction, when adjusting the side of the upper plate 11 of the bearing arranged in the transverse direction, the bridge bearing can move bilaterally in the longitudinal direction and can move unilaterally in the transverse direction;

[0050] In another optional embodiment, in the horizontal direction, the adjustment mechanism 13 is arranged on opposite sides of the support upper plate 11 in the transverse direction, so that the support lower plate 12 can move bilaterally in the longitudinal direction, but the displacement of the bilateral movement in the transverse direction is limited by the adjustment mechanism 13;

[0051] In another optional embodiment, in the horizontal direction, when adjusting the side of the upper plate 11 of the bearing arranged in the longitudinal direction, the bridge bearing can be moved bilaterally in the transverse direction and can be moved unilaterally in the longitudinal direction;

[0053] In the above four embodiments, any combination can be made when the technical solutions do not conflict, for example, adjusting mechanisms 13 are simultaneously set on both sides of the longitudinal and transverse directions to simultaneously control the displacement of the lower plate 12 of the support in the transverse and longitudinal directions; in actual use, the setting position and number of the adjusting mechanisms 13 can be changed according to actual needs, so as to flexibly adjust the displacement of the lower plate 12 of the support in the longitudinal and transverse directions in the horizontal direction, so that the bridge support forms a one-way movable support, a two-way movable support or a fixed support, so that when the operator makes a mistake in the transverse and longitudinal installation of the support, it can also be adjusted in time through the adjusting mechanism 13, and there is no need to disassemble the bridge support again, which greatly improves the tolerance of the installation and saves construction costs. It should be noted that in this application, the displacement of the lower plate 12 of the support is the relative displacement generated between the lower plate 12 of the support and the upper plate 11 of the support, that is, it can be regarded as the displacement of the lower plate 12 of the support relative to the upper plate 11 of the support, and it can also be regarded as the displacement of the upper plate 11 of the support relative to the lower plate 12 of the support.

[0054] In this application, if Figure 2 , Figures 4 to 5The adjusting mechanism 13 includes a limit stopper 132 and a detachable patch 131. One end of the limit stopper 132 is connected to the support upper plate 11, and the limit stopper 132 protrudes toward the support lower plate 12 in the vertical direction, protruding to the side of the support lower plate 12, and there is a spacing between the limit stopper 132 and the support lower plate 12; the other end of the limit stopper 132 is connected to the detachable patch 131, that is, the detachable patch 131 is connected to the lower end of the limit stopper 132, and in the horizontal direction, the detachable patch 131 protrudes toward the support lower plate 12 The detachable patch 131 can adjust the distance between the limit block 132 and the lower plate 12 of the support; the detachable patch 131 is provided with a mounting groove 1311, and the mounting groove 1311 opens upward, that is, the mounting groove 1311 is opened at the upper end of the detachable patch 131, and the inner contour of the mounting groove 1311 is adapted to the outer contour of the limit block 132, so that the inner wall of the mounting groove 1311 fits with the outer wall of the limit block 132, so that the detachable patch 131 is connected to the lower end of the limit block 132 through the mounting groove 1311.

[0055] It should be noted that the limit blocks 132 can be pre-set on the four sides of the support lower plate 12 in the horizontal direction, that is, in the horizontal direction, the limit blocks 132 are set on the opposite sides of the support upper plate 11 in the transverse and longitudinal directions, so that the support lower plate 12 is surrounded by the limit blocks 132 on all sides. When it is necessary to install the removable patch block 131 to adjust the displacement, the removable patch block 131 can be installed to the limit block 132 at the corresponding position. In this way, the horizontal displacement of the support lower plate 12 relative to the support upper plate 11 can be flexibly adjusted, saving maintenance costs.

[0056] like Figure 3 As shown, in the horizontal direction, the length of the limit stopper 132 is greater than or equal to the length of the support lower plate 12, and the length of the limit stopper 132 is less than the length of the support upper plate 11, that is, the limit stopper 132 can completely limit and block the support lower plate 12, and can save materials and manufacturing costs; and the length of the detachable patch 131 is the same as the length of the limit stopper 132, that is, the ends of the detachable patch 131 and the limit stopper 132 are aligned; as shown in FIG. Figure 3 to Figure 4 , Figure 6As shown, the mounting groove 1311 is opened at both ends of the detachable patch block 131, that is, when the detachable patch block 131 and the limit stopper 132 are installed, the detachable patch block 131 can be moved in the horizontal extension direction from the opening of the mounting groove 1311, and the limit stopper 132 can be translated and inserted into the mounting groove 1311 in the horizontal direction to realize the installation connection between the limit stopper 132 and the detachable patch block 131; wherein, the adjustment mechanism 13 also includes a fixing bolt 133 and a fixing card 134, the fixing card 134 is arranged at the end that is flush with the limit stopper 132 and the detachable patch block 131, the fixing card 134 is provided with a jack for inserting the fixing bolt 133, the limit stopper 132 is provided with a mounting hole for installing the fixing bolt 133, the fixing bolt 133 passes through the fixing card 134 and the limit stopper 132 in sequence, thereby realizing the connection between the fixing card 134 and the limit stopper 132, wherein, as Figure 4 As shown, the left side, right side and lower side walls of the fixed card 134 extend beyond the side of the limit block 132 to the removable patch 131, so that the fixed card 134 can limit the removable patch 131, and can effectively prevent the removable patch 131 from shifting relative to the limit block 132 in the extension direction, further ensuring the connection stability between the limit block 132 and the removable patch 131.

[0057] Further, such as Figure 4 , Figure 5 As shown, in the horizontal direction, the detachable patch 131 includes an adjustment portion 1313, which is a portion located between the limit block 132 and the lower bracket seat, and the length of the adjustment portion 1313 in the horizontal plane is L1, and the spacing between the limit block 132 and the adjacent side walls of the support lower plate 12 is L2, wherein, in this embodiment, L2≥L1>0; when L2=L1, the detachable patch 131 completely restricts the displacement of the support lower plate 12 on this side; it should be noted that the length of the adjustment portion 1313 of the detachable patch 131 in the horizontal plane can be set to be different, and when the length of the adjustment portion 1313 is different, the displacement of the support lower plate 12 in this direction by the adjustment mechanism 13 is also different, and then in actual use, by replacing detachable patches 131 of different sizes, it is possible to achieve fine adjustments to the amount of displacement, thereby increasing the adjustment range of the bridge bearing and its scope of application.

[0058] like Figure 4 As shown, in the vertical direction, the top of the adjustment portion 1313 of the removable patch block 131 exceeds the top of the support lower plate 12, or the top of the adjustment portion 1313 is flush with the top of the support lower plate 12, so that when the removable patch block 131 is fully limited to the support lower plate 12, the removable patch block 131 can maximize the contact area with the support lower plate 12 and improve the limiting effect.

[0059] Further, such as Figure 5 As shown, the detachable patch block 131 is provided with a limiting protrusion 1312, the limiting protrusion 1312 is located in the installation groove 1311, the bottom of the limiting protrusion 1312 is connected to the side wall of the installation groove 1311, and the limiting protrusion 1312 protrudes toward the center of the installation groove 1311 in the horizontal direction. Correspondingly, the limiting block 132 is provided with a limiting groove 1321 that matches the limiting protrusion 1312, the limiting groove 1321 is recessed toward the center direction of the limiting block 132, and the limiting groove 1321 opens on the side wall of the limiting block 132; the inner portion of the limiting groove 1321 is provided with a limiting groove 1321 that matches the limiting protrusion 1312. The wall fits with the outer wall of the limiting protrusion 1312, that is, the formation of the limiting groove 1321 matches the limiting protrusion 1312. When the detachable patch block 131 is connected to the limiting block 132 through the installation groove 1311, the limiting protrusion 1312 is inserted into the limiting groove 1321. In the vertical direction, the limiting groove 1321 limits and supports the limiting protrusion 1312, thereby effectively preventing the detachable patch block 131 from being easily disconnected from the limiting block 132 due to its own weight, thereby enhancing the connection stability between the limiting block 132 and the detachable patch block 131.

[0060] Furthermore, the limiting protrusions 1312 are arranged on the opposite side walls of the installation groove 1311, that is, the limiting block 132 can be connected to both sides of the detachable patch block 131; there is at least one limiting protrusion 1312 arranged on each side wall of the installation groove 1311. In this embodiment, preferably, there are 4 limiting protrusions 1312, such as Figure 5 As shown, the limiting protrusions 1312 are evenly divided into two groups and arranged on the opposite side walls of the installation groove 1311, that is, two limiting protrusions 1312 are arranged on each side wall, and the limiting protrusions 1312 of each group are arranged at equal intervals. The limiting protrusions 1312 are preferably arranged in the middle part of the installation groove 1311, which can be evenly stressed and increase the connection stability between the detachable patch 131 and the limiting block 132. The limiting protrusions 1312 can be set to a rectangular, isosceles trapezoidal or arc shape. In this embodiment, the limiting protrusions 1312 are set to a rectangular shape, which can increase the connection stability between the limiting block 132 and the detachable patch 131.

[0061] It should be noted that the various embodiments of the present application can be arbitrarily combined into a new embodiment if the solutions do not conflict and the technical solutions can coexist.
