Description

Technical Field

[0001] This utility model relates to the field of bridge technology, and in particular to a bridge bearing adjustment mechanism. Background Technology

[0002] Bridge bearings are important structural components that connect the superstructure and substructure of a bridge. They are generally erected on piers and abutments, and their top surfaces support the superstructure. Their function is to fix the superstructure to the piers and abutments, bear various forces acting on the superstructure, and reliably transmit them to the piers and abutments. Under the influence of load, temperature, concrete shrinkage and creep, the bearings can adapt to the rotation and displacement of the superstructure, allowing the superstructure to deform freely without generating additional internal forces.

[0003] Each individual beam of a bridge typically has four support points and four bearings. Three points define a plane. When one of the four support points is not on this plane, the bearing at that point becomes detached. This can cause the beam to twist during operation, increase additional structural internal forces, and damage the beam over time, thus shortening the overall service life of the bridge.

[0004] Patent CN206070364U discloses a plate rubber bearing with bidirectional height adjustment, which can quickly and steplessly increase or decrease the height of the plate rubber bearing to avoid detachment. However, the inventors believe that it has a problem with only adjusting the height. That is, sometimes the detachment is not completely equidistant. One side of the plate rubber bearing may be completely detached, while the other side remains in close contact with the bridge, resulting in partial detachment. In this case, the patented device that can only adjust the height cannot solve the problem of partial detachment.

[0005] Therefore, it is necessary to develop a bridge bearing adjustment mechanism to address the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a bridge bearing adjustment mechanism to solve the problem of partial detachment of plate rubber bearings.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses a bridge bearing adjustment mechanism, comprising a height adjustment component and a movable component. The bottom end of the height adjustment component is fixedly connected to the bridge pier; the movable component is movably disposed at the top end of the height adjustment component; the top end of the movable component is in contact with the bottom end of the plate rubber bearing, and the top end of the plate rubber bearing is fixedly connected to the bridge.

[0009] Optionally, the height adjustment component and the movable component are movably connected via a ball joint assembly.

[0010] Optionally, the ball joint assembly includes a spherical groove at the top of the height adjustment component and a spherical protrusion at the bottom of the movable component.

[0012] Optionally, the movable component includes a movable block and a second pad, with the spherical protrusion disposed at the bottom end of the movable block; the second pad is fixed to the top end of the movable block, the top end of the second pad has a planar structure, and the second pad is disposed in contact with the bottom end of the plate rubber support.

[0013] Optionally, the height adjustment assembly includes a lifting block, and the spherical groove is disposed at the top of the lifting block.

[0014] Optionally, the height adjustment assembly further includes a fixing block and a lifting adjustment assembly, wherein the fixing block is used to be fixedly connected to the bridge pier; and the lifting adjustment assembly is disposed between the fixing block and the lifting block.

[0015] Optionally, the lifting adjustment assembly includes a stud and a snap-fit ​​pin, wherein the snap-fit ​​pin is fixed to one end of the stud;

[0016] The snap-fit ​​post is rotatably connected to the fixed block or the lifting block;

[0017] The end of the lifting block or the fixing block near the snap-fit ​​post is threadedly connected to the stud.

[0018] The lifting block or the fixing block has an internal clearance cavity for avoiding the end of the stud that is away from the locking post.

[0019] Optionally, the top periphery of the fixed block is provided with a plurality of first slots, and the bottom periphery of the lifting block is provided with second slots corresponding to the first slots one by one.

Utilizing the movable characteristics of the ball joint component, the movable component can rotate and adjust at a certain angle in the horizontal direction, effectively solving the problem of partial detachment. This allows the plate rubber bearing to evenly bear the load transmitted from the bridge, avoiding torsion and additional structural internal forces caused by partial detachment, and extending the overall service life of the bridge.

[0039] In one specific embodiment of this utility model, such as Figures 1-4 As shown, the height adjustment component includes a lifting block 500, and a spherical groove is provided on the top of the lifting block 500.

[0040] In one specific embodiment of this utility model, such as Figures 1-4 As shown, the height adjustment assembly also includes a fixed block 600 and a lifting adjustment assembly. The fixed block 600 is used to fix it to the bridge pier; the lifting adjustment assembly is disposed between the fixed block 600 and the lifting block 500.

[0041] In one specific embodiment of this utility model, such as Figures 1-4 As shown, the lifting adjustment assembly includes a stud 700 and a snap-fit ​​post 800, with the snap-fit ​​post 800 fixed to one end of the stud 700;

[0042] The snap-fit ​​post 800 is rotatably connected to the fixed block 600 or the lifting block 500; Figures 1 to 3 This is an embodiment where the snap-fit ​​post 800 and the fixing block 600 are rotatably connected. Figure 4 This is an embodiment where the locking post 800 and the lifting block 500 are rotatably connected.

[0043] The snap-fit ​​post 800 has a regular polyhedral prism structure, which facilitates snap-fit ​​with the ratchet wrench.

[0044] A shaft head is fixed to the end of the snap-fit ​​post 800 away from the stud 700. A hole for mounting a bearing is provided on the fixing block 600 or the lifting block 500. The rotating ring of the bearing is fixedly connected to the shaft head. The snap-fit ​​post 800 is rotatably connected to the fixing block 600 or the lifting block 500 through the shaft head and the bearing. The bearing is capable of withstanding axial loads. Alternatively, the shaft head can be fixed to the end of the snap-fit ​​post 800 away from the stud 700, and a blind hole matching the shaft head can be provided on the fixing block 600 or the lifting block 500. The snap-fit ​​post 800 is rotatably connected to the fixing block 600 or the lifting block 500 through the shaft head and the blind hole.

[0045] The end of the lifting block 500 or the fixing block 600 near the snap-fit ​​post 800 is threadedly connected to the stud 700. Figures 1 to 3 This is an embodiment where the stud 700 and the lifting block 500 are threaded together. Figure 4 This is an embodiment of the threaded connection between the stud 700 and the fixing block 600.

[0046] The lifting block 500 or the fixing block 600 has an internal clearance cavity 900 for avoiding the end of the stud 700 away from the locking post 800. Figure 2 and 3 To avoid the cavity 900 being located inside the lifting block 500, the following implementation method is used. Figure 4 This is an embodiment where the clearance cavity 900 is formed inside the fixing block 600. The clearance cavity 900 provides space for the end of the stud 700 away from the locking post 800 during rotation.

[0047] In one specific embodiment of this utility model, such as Figures 1-4 As shown, the top periphery of the fixed block 600 has multiple first slots 1000, and the bottom periphery of the lifting block 500 has second slots 1100 corresponding to the first slots 1000. A guide post 1200 is detachably connected between the first slots 1000 and the second slots 1100. This utility model has four first slots 1000, evenly distributed around the circumference. When adjusting the distance between the fixed block 600 and the lifting block 500, the guide post 1200 is installed. The fixed block 600 and the guide post 1200 limit the lifting block 500, preventing it from rotating. When the locking post 800 drives the stud 700 to rotate, the lifting block 500 can rise or fall.

[0048] In one specific embodiment of this utility model, such as Figures 1-4 As shown, the first slot 1000 has a threaded hole on its side wall near the locking post 800. A bolt is rotatably mounted on the guide post 1200, and the bolt is threadedly connected to the threaded hole. When adjusting the distance between the fixing block 600 and the lifting block 500, the guide post 1200 is installed to prevent the lifting block 500 from rotating along with the stud 700 when it rotates. After adjustment, the guide post 1200 can be removed.

[0049] The working principle of this utility model of a bridge bearing adjustment mechanism is as follows: the bottom end of the height adjustment component is fixedly connected to the bridge pier; the movable component is movably set at the top of the height adjustment component; the top of the movable component is in contact with the bottom end of the plate rubber bearing 100, and the top of the plate rubber bearing 100 is fixedly connected to the bridge. By adjusting the overall height through the height adjustment component, the part of the plate rubber bearing 100 that is not detached remains in close contact with the bridge. At the same time, by utilizing the movable characteristics of the ball joint component, the spherical protrusion at the bottom of the movable block 300 will rotate in the spherical groove at the top of the lifting block 500, so that the movable component can rotate and adjust at a certain angle in the horizontal direction. This makes the second pad 400 at the top of the movable block 300 perpendicular to the axis of the plate rubber bearing 100, thereby effectively solving the problem of partial detachment. This allows the plate rubber bearing 100 to evenly bear the load transmitted from the bridge, avoiding the torsion and additional structural internal forces caused by partial detachment of the bridge, and extending the overall service life of the bridge.

[0050] For height adjustment, install the guide post 1200 and use a ratchet wrench to engage it with the locking post 800. The ratchet wrench drives the locking post 800 to rotate, which in turn drives the stud 700 to rotate. This changes the distance between the fixed block 600 and the lifting block 500, thereby adjusting the height of the plate rubber support 100. After adjustment, the guide post 1200 can be removed.

[0051] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.

[0052] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
