The longitudinal belt of the transverse movable bearing has a limit device, so it can only produce transverse movement; the transverse belt of the longitudinal movable bearing has a limit device, so it can only produce longitudinal movement; the transverse and longitudinal belt of the bidirectional movable bearing have no limit devices, so it can produce transverse and longitudinal movement. According to different forms, it can be divided into flat plate bearings, plate rubber bearings, spherical bearings, steel bearings, etc. Among them, the spherical bearing has the characteristics of strong bearing capacity and large horizontal displacement of the pot-type rubber bearing due to its consistent rotation performance in all directions, and it can adapt to the needs of large rotation angles and is widely used in various types of bridges.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] See also Figure 1 and Figure 2 As shown, an embodiment of the present application provides a temporary limiting device for a movable spherical bearing, wherein the movable spherical bearing 1 is a transverse movable bearing or a longitudinal movable bearing, both of which include an upper bearing 10, a lower bearing 11, a slider 13 and two groups of anchor rod assemblies 12, wherein the upper bearing 10 is movably disposed on the lower bearing 11 through the slider 13; the two groups of anchor rod assemblies 12 are disposed on both sides of the lower bearing 11, and the anchor rod assemblies 12 include a plurality of anchor rods 120 penetrating the lower bearing 11, wherein the plurality of anchor rods 120 are arranged at intervals along the length direction of the lower bearing 11, and form a space 2 with the upper bearing 10, and the lower bearing 11 is connected to the bridge pier through the anchor rods.

[0035] See also Figure 3 As shown, when the movable spherical bearing 1 is a transverse movable bearing, the movable bearing has a longitudinal limiting device, which includes two limiting plates. The two limiting plates are arranged on both sides of the lower bearing 11 along the longitudinal bridge direction to limit the movement of the upper bearing 10 along the longitudinal bridge direction, so that the movable bearing can only move along the transverse bridge direction, and the anchor rod assembly 12 of the movable bearing is arranged on both sides of the lower bearing 11 along the transverse bridge direction, and two groups of anchor rod assemblies 12 form two spaces 2 between the upper bearing 10 respectively.

[0036] See also Figure 5 As shown, when the movable spherical bearing 1 is a longitudinal movable bearing, the movable bearing has a transverse limiting device, which includes two limiting plates. The two limiting plates are arranged on both sides of the lower bearing 11 along the transverse bridge direction to limit the movement of the upper bearing 10 along the transverse bridge direction, so that the movable bearing can only move along the longitudinal bridge direction, and the anchor rod assembly 12 of the movable bearing is arranged on both sides of the lower bearing 11 along the longitudinal bridge direction, and two groups of anchor rod assemblies 12 form two spaces 2 between the upper bearing 10 respectively.

[0037] The temporary limiting device of the embodiment of the present application includes two first limiting components 30, and the first limiting components 30 have a use state. When in the use state, the two first limiting components 30 are respectively arranged in the two spaces 2 to fill the spaces 2, and the two sides of the first limiting components 30 are respectively abutted against the anchor rod 120 and the upper support 10 to limit the lateral movement of the upper support 10 of the lateral movable support and the longitudinal movement of the upper support 10 of the longitudinal movable support. By using the anchor rod 120 on the lateral movable support and the longitudinal movable support, a temporary limiting device for limiting the movement of the upper support 10 of the lateral movable support and the longitudinal movable support is formed together with the first limiting components 30.

[0038] The use principle of the temporary limiting device in the embodiment of the present application is:

[0039] When the movable spherical bearing 1 is a transverse movable bearing or a longitudinal movable bearing, the longitudinal movement of the upper bearing 10 of the transverse movable bearing has been restricted, and the transverse movement of the upper bearing 10 of the longitudinal movable bearing has been restricted. When the temporary limiting device of the embodiment of the present application is used, the two first limiting components 30 are respectively arranged in the two spaces 2 of the transverse movable bearing or the longitudinal movable bearing, and the two sides of the first limiting component 30 are respectively abutted against the anchor rod 120 and the upper bearing 10 to limit the transverse movement of the upper bearing 10 of the transverse movable bearing and the longitudinal movement of the upper bearing 10 of the longitudinal movable bearing, so as to ensure the safety of construction, and the first limiting component 30 is not fixedly connected with the upper bearing 10, the lower bearing 11 and the anchor rod 120, and the first limiting component 30 only plays a temporary limiting role. After the bridge construction is completed, the first limiting component 30 can be removed at any time.

[0040] Optional, see Figure 2 As shown, the upper support 10 includes an upper seat body 100, the center of the upper seat body 100 is convex downward and formed with an upper ball pendulum 101, the bottom end of the upper ball pendulum 101 is concave inward to form a concave spherical surface, the top end of the slider 13 is convex upward to form a convex spherical surface adapted to the concave spherical surface, and the upper ball pendulum 101 is connected to the slider 13; see Figure 3 As shown, the first limit assembly 30 includes a first limit baffle 300 and a plurality of screw rods 301. The first limit baffle 300 is provided with a plurality of threaded holes pendulum-piercing the first limit baffle 300. One side of the first limit baffle 300 is abutted against the anchor rod 120. Each screw rod 301 corresponds to a threaded hole, and the screw rod 301 is threadedly connected in the threaded hole, with one end thereof extending out of the threaded hole and abutting against the upper ball pendulum 101.

[0041] Preferably, see Figure 4 As shown, a plurality of mounting grooves 304 are further provided on the first limiting baffle 300 , each mounting groove 304 corresponds to an anchor rod 120 , and the mounting groove 304 is used to be clamped on the nut 1200 of the anchor rod 120 . When the movable spherical support 1 is a transverse movable support, the distance between the screw 301 and the upper ball pendulum 101 is small. If the width of the first limit baffle 300 is designed according to the distance between the screw 301 and the upper ball pendulum 101, the width of the first limit baffle 300 will be too narrow and the strength will be insufficient. Therefore, the first limit baffle 300 is made wider, but this will cause interference between the first limit baffle 300 and the screw 301, and the first limit baffle 300 cannot be placed in the space 2. Therefore, an installation groove 304 is opened on the first limit baffle 300 to enable the first limit baffle 300 to be placed in the space 2, and the width of the installation groove 304 is smaller than the diameter of the nut 1200 of the anchor rod 120, so that the installation groove 304 is clamped on the screw 301, and the first limit baffle 300 will not fall off the anchor rod 120.

[0042] For further information, see Figure 5As shown, both side edges of the upper ball pendulum 101 and the two first limit baffles 300 on the same side are convex outward to form a convex spherical surface 103. When the movable spherical support 1 is a longitudinal movable support, the distance between the screw 301 and the upper ball pendulum 101 is very large. If the width of the first limit baffle 300 is increased, the first limit baffle 300 cannot be directly placed in the space 2. Therefore, the first limit assembly 30 of the embodiment of the present application also includes a second limit baffle 302. The second limit baffle 302 and the first limit baffle 300 can fill the space 2 together, and also The second limit baffle 302 and the first limit baffle 300 can both be placed in the space 2, and the second limit baffle 302 is arranged between the first limit baffle 300 and the upper ball pendulum 101, and the side surface of the second limit baffle 302 in contact with the upper ball pendulum 101 is recessed inward to form a concave spherical surface 303 that matches the convex spherical surface 103, so that the second limit baffle 302 can better support the upper ball pendulum 101; one end of the screw rod 301 extends out of the threaded hole and is pressed on the second limit baffle 302, so that the second limit baffle 302 can support the upper ball pendulum 101. The screw rod 301 presses the second limit baffle 302, and the second limit baffle 302 presses the upper ball pendulum 101, so that the two sides of the baffle formed by the second limit baffle 302 and the first limit baffle 300 are respectively pressed against the upper ball pendulum 101 and the screw rod 301 to limit the movement of the movable spherical support.

[0043] Preferably, see Figure 6 As shown, when the movable spherical support 1 is a bidirectional movable support, the movable support is not provided with a limiting device, and the upper support 10 can move along the longitudinal bridge direction and the transverse bridge direction, and the anchor rod assembly 12 of the movable support is arranged on both sides of the lower support 11 along the transverse bridge direction, and two groups of anchor rod assemblies 12 respectively form two spaces 2 with the upper support 10. When limiting the bidirectional movable support, two first limiting assemblies 30 are respectively arranged in the two spaces 2, and the two sides of the first limiting assemblies 30 are respectively abutted against the anchor rod 120 and the upper support 10 to limit the transverse movement of the upper support 10 of the bidirectional movable support. The temporary limiting device also includes two second limiting assemblies 40, which are arranged on two first limiting baffles 300 and are used to clamp on both sides of the upper seat body 100 to limit the longitudinal movement of the upper seat body 100, thereby limiting the transverse and longitudinal movement of the bidirectional movable support.

[0044] For further information, see Figure 7 As shown, the second limiting assembly 40 includes two extensions 400 and two clamping ends 401. The two extensions 400 are respectively arranged at the two ends of the first limiting baffle 300; the clamping ends 401 are formed by the extensions 400 extending upward; and a clamping space for limiting the movement of the upper seat 100 is formed between all the clamping ends 401. When the temporary limiting device is used, the upper seat 100 is clamped in the clamping space to limit the longitudinal movement of the upper seat 100.

[0045] Furthermore, the extension part 400 of the second position-limiting assembly 40 of the embodiment of the present application can be detachably connected to or integrally formed with the first position-limiting baffle 300. Preferably, the extension part 400 is integrally formed with the first position-limiting baffle 300, and the extension part 400 is formed by extending outward from one end of the first position-limiting baffle 300. When temporarily limiting the bidirectional movable support, only the first position-limiting assembly 30 needs to be installed, and then the second position-limiting assembly 40 can be installed at the same time, which greatly saves construction time and improves construction efficiency.

[0046] See also Figure 1 and Figure 2 As shown, an embodiment of the present application also provides a method for using a temporary limiting device for a movable spherical support, wherein the movable spherical support 1 includes an upper support 10, a lower support 11 and two groups of anchor rod assemblies 12, wherein the upper support 10 is movably disposed on the lower support 11 through a slider 13; the two groups of anchor rod assemblies 12 are disposed on both sides of the lower support 11, and the anchor rod assemblies 12 include a plurality of anchor rods 120 penetrating the lower support 11, and the plurality of anchor rods 120 are arranged at intervals along the length direction of the lower support 11, and form a space 2 between the anchor rods 120 and the upper support 10.

[0047] See also Figure 3 As shown, when the movable spherical bearing 1 is a transverse movable bearing, the movable bearing has a longitudinal limiting device, which includes two limiting plates. The two limiting plates are arranged on both sides of the lower bearing 11 along the longitudinal bridge direction to limit the movement of the upper bearing 10 along the longitudinal bridge direction, so that the movable bearing can only move along the transverse bridge direction, and the anchor rod assembly 12 of the movable bearing is arranged on both sides of the lower bearing 11 along the transverse bridge direction, and two groups of anchor rod assemblies 12 form two spaces 2 between the upper bearing 10 respectively.

[0048] See also Figure 5 As shown, when the movable spherical bearing 1 is a longitudinal movable bearing, the movable bearing has a transverse limiting device, which includes two limiting plates. The two limiting plates are arranged on both sides of the lower bearing 11 along the transverse bridge direction to limit the movement of the upper bearing 10 along the transverse bridge direction, so that the movable bearing can only move along the longitudinal bridge direction, and the anchor rod assembly 12 of the movable bearing is arranged on both sides of the lower bearing 11 along the longitudinal bridge direction, and two groups of anchor rod assemblies 12 form two spaces 2 between the upper bearing 10 respectively.

[0052] S2: After the construction of the bridge and the pier is completed, the first limiting assembly 30 is removed. Since the first limiting assembly 30 is not fixedly connected to the upper support 10, the lower support 11 and the anchor rod 120, the first limiting assembly 30 only plays a temporary limiting role. After the bridge construction is completed, the first limiting assembly 30 can be removed at any time.

[0053] See also Figure 6 As shown, when the movable spherical support 1 is a bidirectional movable support, the first limit assembly 30 includes a first limit baffle 300 and a plurality of screws 301. The first limit baffle 300 is provided with a plurality of threaded holes penetrating the first limit baffle 300. One side of the first limit baffle 300 abuts against the anchor rod 120. Each screw 301 corresponds to a threaded hole, and the screw 301 is screwed into the threaded hole, one end of which extends out of the threaded hole and abuts against the upper ball pendulum 101.
